Item 1.01. Entry into a Material Definitive Agreement.

On May 18, 2026, Advanced Energy Industries, Inc. (the “Company”)

completed its previously announced private unregistered offering of $1.15 billion aggregate principal amount of its 0% Convertible Senior

Notes due 2031 (the “Notes”), which amount includes the full exercise of the initial purchasers’ option to purchase

up to $150.0 million aggregate principal amount of additional Notes.

Indenture and Notes

The Notes were issued under an Indenture (the “Indenture”),

dated as of May 18, 2026, by and between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”).

The Indenture provides, among other things, that the Notes will not bear regular interest, and the principal amount of the notes will

not accrete. The Notes will mature on May 15, 2031, unless earlier repurchased or redeemed by the Company or converted pursuant to

their terms.

The Company received net proceeds from the offering of the Notes of

approximately $1,128.1 million, after deducting the initial purchasers’ discounts and after deducting offering expenses payable

by the Company. The Company used $69.0 million of the net proceeds from the offering to pay the cost of the Capped Call Confirmations

entered into in connection with the offering, as described below. In addition, the Company paid approximately $442.4 million of the net

proceeds from the offering and issued approximately 1.98 million shares of the Company’s common stock, par value $0.001 per share

(“Common Stock”), collectively, in exchange for approximately $438.3 million aggregate principal amount of its previously

issued 2.50% Convertible Senior Notes due 2028 (the “2028 Convertible Notes”), as described below. The Company intends to

use the remainder of the net proceeds from the offering for general corporate purposes.

The Company may not redeem the Notes prior to May 21, 2029, except

in the event of a cleanup redemption as described below. The Company may redeem for cash all or any portion of the Notes, at the Company’s

option at any time and from time to time, on or after May 21, 2029 if the last reported sale price of the Common Stock has been at

least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any consecutive 30

trading-day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the

date on which the Company provides the related notice of optional redemption (an “Optional Redemption”). In addition, the

Company may redeem for cash, all but not less than all, of the Notes at any time if the amount of the Notes that remains outstanding is

less than 25% of the aggregate principal amount of the Notes initially issued under the Indenture (a “Cleanup Redemption”).

The redemption price for any Optional Redemption or Cleanup Redemption will be 100% of the principal amount of the Notes to be redeemed,

plus accrued and unpaid special interest, if any, to, but excluding, the relevant redemption date. No sinking fund is provided

for the Notes.

Prior to the close of business on the business day immediately preceding

February 15, 2031, holders of the Notes may convert their Notes at their option only under the following circumstances: (i) during

the 30 trading day period beginning on, and including, the 21st trading day of any fiscal quarter commencing after the fiscal quarter

ending on June 30, 2026, if the last reported sale price per share of the Common Stock exceeds 130% of the conversion price for each

of at least five trading days (whether or not consecutive) during the first 20 trading days of such fiscal quarter (ii) during the

five-business day period after any five-consecutive trading day period (the “measurement period”) in which the trading price

(as defined below) per $1,000 principal amount of the Notes for each trading day of the measurement period was less than 98% of the product

of the last reported sale price of the Common Stock and the conversion rate on each such trading day; (iii) if the Company calls

any or all of the Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding

the redemption date; or (iv) upon the occurrence of specified corporate events. On or after February 15, 2031, until the close

of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their Notes at any time,

regardless of the foregoing circumstances.

Upon conversion, the Company will pay cash up to the aggregate principal

amount of the Notes to be converted and pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and

Common Stock at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess

of the aggregate principal amount of the Notes being converted. The initial conversion rate is 1.9655 shares of Common Stock per $1,000

principal amount of Notes (which is equivalent to an initial conversion price of approximately $508.78 per share). The conversion rate

is subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture. In addition, following certain

corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption, the Company will increase, in

certain circumstances, the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or notice

of redemption. The maximum number of shares of Common Stock issuable in connection with the conversion of the Notes is 3,390,430.

Upon the occurrence of a fundamental change (as defined in the Indenture),

subject to certain conditions, holders of the Notes may require the Company to repurchase all or a portion of the Notes for cash at a

price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any, to,

but excluding, the repurchase date.

The Indenture contains customary events of default. In the event of

certain events of bankruptcy, insolvency or reorganization involving the Company or any of its significant subsidiaries, 100% of the principal

of the Notes plus accrued and unpaid special interest, if any, may be declared immediately due and payable, subject to certain

conditions in the Indenture. In the case of any other event of default, the Trustee or the holders of at least 25% in aggregate principal

amount of the then-outstanding Notes may declare the Notes to be due and payable immediately.

The initial purchasers and their respective affiliates have in the

past performed commercial banking, investment banking and advisory services for the Company from time to time for which they have received

customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for the Company

in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses.

The foregoing descriptions of the Indenture and the Notes are qualified

in their entirety by reference to the full text of the Indenture and the Form of Global 0% Convertible Senior Note due 2031, copies

of which are filed as Exhibits 4.1 and 4.2, respectively, to this Current Report on Form 8-K (this “Current Report”)

and are incorporated herein by reference.

Capped Call Transactions

In connection with the pricing of the Notes on May 13, 2026 and

the exercise of the initial purchasers’ option to purchase additional Notes on May 14, 2026, the Company entered into privately

negotiated capped call transactions (collectively, the “Capped Call Confirmations”) with certain of the initial purchasers

or their respective affiliates and other financial institutions (the “Counterparties”). The Capped Call Confirmations cover,

subject to anti-dilution adjustments substantially similar to those applicable to the Notes, the number of shares of Common Stock initially

underlying the Notes, and are expected generally to reduce potential dilution to the Common Stock upon any conversion of Notes and/or

offset any cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be, with

such reduction and/or offset subject to a cap.

The Capped Call Confirmations are expected generally to reduce potential

dilution to the Common Stock upon any conversion of the Notes and/or offset any cash payments the Company is required to make in excess

of the principal amount of the converted Notes, as the case may be, in the event that the market price per share of the Common Stock,

as measured under the terms of the Capped Call Confirmations, is greater than the strike price of the Capped Call Confirmations, which

initially corresponds to the conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those

applicable to the conversion rate of the Notes. The Capped Call Confirmations are separate transactions entered into by the Company with

the Counterparties and are not part of the terms of the Notes. Holders of the Notes do not have any rights with respect to the Capped

Call Confirmations. A copy of the form of Capped Call Confirmation is filed as Exhibit 10.1 to this Current Report and is incorporated

by reference herein. The foregoing description of the terms of the Capped Call Confirmations does not purport to be complete and is qualified

in its entirety by reference to such exhibit.

The Exchange Agreements

On May 13, 2026, the Company entered into privately negotiated

exchange agreements (the “Exchange Agreements”) with certain holders of its outstanding 2028 Convertible Notes pursuant to

which such holders exchanged an aggregate of approximately $438.3 million principal amount of 2028 Convertible Notes for aggregate consideration

consisting of approximately $442.4 million in cash and approximately 1.98 million shares of Common Stock (such transactions, the “Exchange

Transactions”), in each case, pursuant to exemptions from registration under the Securities Act of 1933, as amended (the “Securities

Act”), and the rules and regulations thereunder. The 2028 Convertible Notes were previously issued pursuant to an indenture,

dated as of September 12, 2023 (the “2028 Convertible Notes Indenture”), between the Company and U.S. Bank Trust Company,

National Association, as trustee. Following the closing of the Exchange Transactions, approximately $136.7 million in aggregate principal

amount of 2028 Convertible Notes remain outstanding with terms unchanged. The 2028 Convertible Notes exchanged in the Exchange Transactions

have been surrendered to the trustee for cancellation in accordance with the terms of the 2028 Convertible Notes Indenture.

A copy of the form of exchange agreement, substantially in the form

entered into on May 13, 2026 with the exchanging holders in the Exchange Transactions, is filed as Exhibit 10.2 to this Current

Report and is incorporated herein by reference. The foregoing description of the Exchange Agreements does not purport to be complete and

is qualified in its entirety by reference to such exhibit.

Unwind of Existing Call Spread Transactions

In connection with the issuance of the 2028 Convertible Notes, the

Company entered into convertible note hedge transactions (the “Existing Hedge Transactions”) and separate warrant transactions

(the “Existing Warrant Transactions” and, together with the Existing Hedge Transactions, the “Existing Call Spread Transactions”)

with certain financial institutions (the “Existing Counterparties”). In connection with the Exchange Transactions, the Company

entered into agreements with the Existing Counterparties to partially unwind (i) the Existing Hedge Transactions in a notional amount

corresponding to the principal amount of 2028 Convertible Notes exchanged (the “Bond Hedge Unwind Agreements”) and (ii) the

Existing Warrant Transactions with respect to a number of shares equal to the notional shares underlying such 2028 Convertible Notes exchanged

(the “Warrant Unwind Agreements” and, together with the Bond Hedge Unwind Agreements, the “Unwind Agreements”).

In connection with such partial unwind, the Company received on a net basis from the Existing Counterparties an aggregate of approximately

$44.6 million.

Copies of the form of Bond Hedge Unwind Agreement and the form of Warrant

Unwind Agreement are filed as Exhibits 10.3 and 10.4, respectively, to this Current Report and are incorporated herein by reference. The

foregoing descriptions of the Unwind Agreements do not purport to be complete and are qualified in their entirety by reference to such

exhibits.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation

under an Off-Balance Sheet Arrangement of a Registrant.

The disclosures set forth in Item 1.01 of this Current Report are incorporated

herein by reference.

Item 3.02. Unregistered Sales of Equity Securities.

The disclosures set forth in Item 1.01 of this Current Report are incorporated

herein by reference.

The offer and sale of the Notes to the initial purchasers were made

in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act, and for resale by the initial

purchasers to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities

Act. The Company relied on these exemptions from registration based in part on representations made by the initial purchasers in the purchase

agreement pursuant to which the Company sold the Notes to the initial purchasers. Any shares of Common Stock issuable upon conversion

of the Notes will be issued in transactions anticipated to be exempt from registration under the Securities Act pursuant to Section 3(a)(9) thereof.

The shares of Common Stock issued in the Exchange Transactions were

issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. The Company relied

on this exemption from registration based in part on representations made by the exchanging holders in the Exchange Agreements.

listed or, if the Common Stock (or such other security) is not then listed on a U.S. national or regional securities exchange, on the

principal other market on which the Common Stock (or such other security) is then traded and (ii) a Last Reported Sale Price for

the Common Stock (or closing sale price for such other security) is available on such securities exchange or market; provided

that if the Common Stock (or such other security) is not so listed or traded, “Trading Day” means a Business Day;

reasonably be obtained by the Bid Solicitation Agent but two such bids are obtained, then the average of the two bids shall be used,

and if only one such bid can reasonably be obtained by the Bid Solicitation Agent, that one bid shall be used. If the Bid Solicitation

Agent cannot reasonably obtain at least one bid for $5,000,000 principal amount of Notes from a nationally recognized securities dealer

date.

and Amount. The Notes shall be designated as the “0% Convertible Senior Notes due 2031.” The aggregate principal amount

of Notes that may be authenticated and delivered under this Indenture is initially limited to $1,150,000,000, subject to ‎Section 2.10

and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes to the

extent expressly permitted hereunder.

Section 2.02. Form of

Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective

forms set forth in Exhibit A, the terms and provisions of which shall constitute part of, and are hereby expressly incorporated

in and made a part of, this Indenture. To the extent applicable, the Company and the Trustee, by their execution and delivery of this

Indenture, expressly agree to such terms and provisions and to be bound thereby. In the case of any conflict between this Indenture and

a Note, the provisions of this Indenture shall govern and control.

Any Global Note may be endorsed

with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture

as may be required by the Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation thereunder

or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or

traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions

to which any particular Notes are subject.

Any of the Notes may have

such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officer executing the same

may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture,

or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation

of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to

usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

Each Global Note shall represent

such principal amount of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate

principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes

represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, cancellations, conversions, transfers

or exchanges of Notes permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount

of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner

and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including the Redemption

Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest on, a Global Note shall

be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive

payment is provided for herein.

Section 2.03. Date

and Denomination of Notes; No Regular Interest; Special Interest and Defaulted Amounts. (a) The Notes shall be issuable in registered

form without coupons in minimum denominations of $1,000 principal amount and integral multiples thereof. Each Note shall be dated the

date of its authentication and shall not bear regular interest, and the principal amount of the Notes shall not accrete. Special Interest

on the Notes, if any, shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the

basis of the number of days actually elapsed in a 30-day month.

(b)            The

Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Special Interest

Record Date with respect to any Special Interest Payment Date shall be entitled to receive any Special Interest payable on such Special

Interest Payment Date. The principal amount of any Note (x) in the case of any Physical Note, shall be payable at the office or

agency of the Company maintained by the Company for such purposes in the contiguous United States of America, which shall initially be

the Corporate Trust Office and (y) in the case of any Global Note, shall be payable by wire transfer of immediately available funds

to the account of the Depositary or its nominee. The Company shall pay (or cause the Paying Agent to pay) any Special Interest (i) on

any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $5,000,000 or less, by check mailed

to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical Notes having

an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon written application by such a Holder

to the Note Registrar not later than the relevant Special Interest Record Date, by wire transfer in immediately available funds to that

Holder’s U.S. dollar account within the United States (if such Holder has provided the Company, the Trustee or the Paying Agent

with the requisite information necessary to make such wire transfer), which application shall remain in effect until the Holder notifies,

in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the

account of the Depositary or its nominee.

Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date and shall not accrue interest unless

Special Interest was payable pursuant to this Indenture on the relevant payment date, in which case such Defaulted Amounts shall accrue

interest per annum at the then-applicable Special Interest rate borne by the Notes, subject to the enforceability thereof under applicable

law, from, and including, such relevant payment date, and such Defaulted Amounts together with any such interest thereon shall be paid

by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i)            The

Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes)

are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the

following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each

Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless

the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal

to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such

deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons

entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment

of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and

not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee

in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed

payment of such Defaulted Amounts and the special record date therefor to be delivered to each Holder not less than 10 days prior to

such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so

delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered

at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this

‎Section 2.03‎(c).

(ii)            The

Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities

exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required

by such exchange or automated quotation system and the Depositary, if, after written notice given by the Company to the Trustee of the

proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

(iii)            The

Trustee shall not be under any duty or responsibility to any Holders to determine the Defaulted Amounts, or with respect to the nature,

extent or calculation of the Defaulted Amounts owed, or with respect to the method employed in such calculation of the Defaulted Amounts.

Section 2.04. Execution,

Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile

signature of its Chief Executive Officer, President, Chief Financial Officer, Treasurer, Secretary or any of its Executive or Senior

Vice Presidents.

At any time and from time

to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for

authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such

Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder.

Only such Notes as shall

bear thereon a certificate of authentication substantially in the form set forth on the Form of Note attached as Exhibit A

hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided

by ‎Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate

by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so

authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the

Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated

and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of

as though the person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of

the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the

date of the execution of this Indenture any such person was not such an Officer.

Section 2.05. Exchange

and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate

Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to

‎Section 4.02, the “Note Register”) in which, subject to such reasonable regulations as it may prescribe,

the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form

capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “Note

Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more

co-Note Registrars in accordance with ‎Section 4.02.

Upon surrender for registration

of transfer of any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth

in this ‎Section 2.05, the Company shall execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver,

in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate

principal amount and bearing such restrictive legends as may be required by this Indenture.

Notes may be exchanged for

other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at

any such office or agency maintained by the Company pursuant to ‎Section 4.02. Whenever any Notes are so surrendered for exchange,

the Company shall execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, the Notes that the Holder

making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

All Notes presented or surrendered

for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar

or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory

to the Note Registrar and the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be

imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of

transfer of Notes, but the Company or the Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar

issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or

registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the

Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered

for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, (ii) any

Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with ‎Article 15 or (iii) any

Notes selected for an Optional Redemption or Cleanup Redemption in accordance with ‎Article 16, except the unredeemed portion

of any Note being redeemed in part pursuant to an Optional Redemption.

All Notes issued upon any

registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing

the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or

exchange.

(b)            So

long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth

paragraph from the end of ‎Section 2.05(c) all Notes shall be represented by one or more Notes in global form (each, a

“Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange

of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary

(but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and

the procedures of the Depositary therefor. None of the Trustee, the Paying Agent nor the Conversion Agent shall have any responsibility

or liability for any act or omission of Depositary.

Note that bears or is required under this ‎Section 2.05(c) to bear the legend set forth in this ‎Section 2.05(c) (together

with any Common Stock issued upon conversion of the Notes that is required to bear the legend set forth in ‎Section 2.05(d),

collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this ‎Section 2.05(c) (including

the legend set forth below), unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company,

and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions

on transfer. As used in this ‎Section 2.05(c) and ‎Section 2.05(d), the term “transfer” encompasses

any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “Resale

Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance

of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later

date, if any, as may be required by applicable law, any certificate evidencing such Note (and all securities issued in exchange therefor

or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in ‎Section 2.05(d),

if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration

statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such

transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under

the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

THIS SECURITY AND THE COMMON

STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED

(THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH

THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

(1)            REPRESENTS

THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER

THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

(2)            AGREES

FOR THE BENEFIT OF ADVANCED ENERGY INDUSTRIES, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE

TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL

ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO

AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A)            TO

THE COMPANY OR ANY SUBSIDIARY THEREOF, OR

(B)            PURSUANT

TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

A PERSON REASONABLY BELIEVED TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

(D)            PURSUANT

TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION

REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION

OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF

SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER

IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY

OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

No transfer of any Note prior

to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment

and Transfer has been checked.

Any Note (or security issued

in exchange or substitution therefor) (i) as to which such restrictions on transfer shall have expired in accordance with their

terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective

under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to

the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon

surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this ‎Section 2.05, be exchanged

for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this ‎Section 2.05(c) and

shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the Custodian in writing to so surrender any

Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have

been satisfied, and, upon such instruction, the Custodian shall so surrender such Global Note for exchange; and any new Global Note so

exchanged therefor shall not bear the restrictive legend specified in this ‎Section 2.05(c) and shall not be assigned a

restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale Restriction Termination

Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the

Notes has been declared effective under the Securities Act.

Notwithstanding any other

provisions of this Indenture (other than the provisions set forth in this ‎Section 2.05(c)), a Global Note may not be transferred

as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary

or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor

Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second

immediately succeeding paragraph.

The Depositary shall be a

clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with

respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the name of Cede &

Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

If (i) the Depositary

notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor

depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange

Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred

and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the

Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate, an Opinion of Counsel and a Company Order for

the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such

beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial

interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or

a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such

Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in

exchange for all or a part of the Global Note pursuant to this ‎Section 2.05(c) shall be registered in such names and in

such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or,

in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee in

writing. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical

Notes are so registered.

At such time as all interests

in a Global Note have been converted, canceled, repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof,

canceled by the Trustee in accordance with the applicable procedures and existing instructions between the Depositary and the Custodian.

At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased,

redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part

of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing

between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made

on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

None of the Company, the

Trustee or any agent of the Company or the Trustee shall have any responsibility or liability to any beneficial owner of a Global Note,

a member of, or a participant in, the Depositary or any other Person for any aspect of the records relating to or payments made on account

of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership

interests. All notices and communications to be given to the Holders and all payments made to the Holders in respect of the Notes shall

be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case

of a Global Note), in the manner set forth in ‎Section 17.03. The Trustee may rely and shall be fully protected in relying upon

information furnished by the Depositary with respect to its members, participants and any beneficial owners.

(d)            Until

the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Note shall bear

a legend in substantially the following form (unless such Common Stock has been transferred pursuant to a registration statement that

has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant

to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or such

Common Stock has been issued upon conversion of a Note that has transferred pursuant to a registration statement that has become or been

declared effective under the Securities Act and that continues to be effective at the time of such transfer, or pursuant to the exemption

from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed

by the Company with written notice thereof to the Trustee and any transfer agent for the Common Stock):

Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Company (or

any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by such Affiliate

(or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration

requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a

“restricted security” (as defined under Rule 144). The Company shall cause any Note that is repurchased or owned by

it to be surrendered to the Trustee for cancellation in accordance with ‎Section 2.08.

(f)            The

Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed

under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between

or among members or, or participants in, the Depositary or beneficial owners of interests in any Global Note) other than to require delivery

of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by

the terms of, this Indenture, and to examine the same to determine substantial compliance to form with respect to the express requirements

hereof.

(g)            Notwithstanding

anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for ascertaining whether any

transfer complies with the registration provisions of, or exemptions from, the Securities Act, applicable state securities laws or other

applicable law.

(h)            In

connection with any proposed exchange of Physical Notes for a Global Note, the Company shall be required to provide or cause to be provided

to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without

limitation any cost basis reporting obligations under Section 6045 of the Code.

(i)            The

Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

Section 2.06. Mutilated,

Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion

may execute, and upon receipt of a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and

deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated

Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note

shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required

by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in

every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such

authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating

agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee,

the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee,

the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company or the Trustee

may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection

therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note

that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered

for required repurchase or is about to be converted in accordance with ‎Article 14 shall become mutilated or be destroyed, lost

or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert

or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the

applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent

such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by

or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee

and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note

and of the ownership thereof.

Every substitute Note issued

pursuant to the provisions of this ‎Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute

an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and

shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately

with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express

condition that the foregoing provisions are exclusive with respect to the replacement, payment, redemption, conversion or repurchase

of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute

existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, conversion or repurchase of negotiable

instruments or other securities without their surrender.

Section 2.07. Temporary

Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by

the Trustee shall, upon receipt of a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes

shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions

and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be

executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the

same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the

Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than

any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to ‎Section 4.02

and, upon receipt of a Company Order, the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary

Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without

any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the

same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08. Cancellation

of Notes Paid, Converted, Etc. The Company shall cause all Notes surrendered for the purpose of payment, repurchase, redemption,

registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s

agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled

promptly by it in accordance with its customary procedures. Except for any Notes surrendered for registration of transfer or exchange,

or as otherwise expressly permitted by any of the provisions of this Indenture, no Notes shall be authenticated in exchange for any Notes

surrendered to the Trustee for cancellation. The Trustee shall dispose of canceled Notes in accordance with its customary procedures

and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in

a Company Order.

Section 2.09. CUSIP

Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee

shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that the Trustee

shall have no liability for any defect in the CUSIP numbers as they appear on any Note, notice or elsewhere and any such notice may state

that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance

may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing

of any change in the “CUSIP” numbers.

Section 2.10. Additional

Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding ‎Section 2.01, reopen this Indenture

and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue

date, the issue price and Special Interest, if any, accrued prior to the issue date of such additional Notes) in an unlimited aggregate

principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S.

federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes,

the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s

Certificate and Opinion of Counsel to cover such matters, in addition to those required by ‎Section 17.05, as the Trustee shall

reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such

Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or

through a private offer or public tender or exchange offer or through counterparties to private agreements, including by cash-settled

swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps

or other derivatives) to be surrendered to the Trustee for cancellation in accordance with ‎Section 2.08 and such Notes shall

no longer be considered outstanding under this Indenture upon their surrender.

Article 3

Satisfaction and Discharge

Section 3.01. Satisfaction

and Discharge. This Indenture and the Notes shall upon request of the Company contained in an Officer’s Certificate cease to

be of further effect, and the Trustee, at the expense of the Company, shall execute such instruments reasonably requested by the Company

acknowledging satisfaction and discharge of this Indenture and the Notes, when (a) (i) all Notes theretofore authenticated

and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided

in ‎Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee

or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Redemption Date,

any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash and shares of Common Stock, if any (solely to satisfy

the Company’s Conversion Obligation), if applicable, sufficient to pay all of the outstanding Notes and all other sums due and

payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and

an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this

Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture and the Notes, the obligations of

the Company to the Trustee under ‎Section 7.06 shall survive.

Article 4

Particular Covenants of the Company

Section 4.01. Payment

of Principal and Special Interest. The Company covenants and agrees that it will cause to be paid the principal (including the Redemption

Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest on, each of the Notes

at the places, at the respective times and in the manner provided herein and in the Notes.

Section 4.02. Maintenance

of Office or Agency. The Company will maintain in the contiguous United States of America an office or agency where the Notes may

be surrendered for registration of transfer or for exchange or for presentation for payment or repurchase (“Paying Agent”)

or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes

and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location,

of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish

the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust

Office or the office or agency of the Trustee in the contiguous United States of America.

The Company may also from

time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for

any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission

shall in any manner relieve the Company of its obligation to maintain an office or agency in the contiguous United States of America

for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change

in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent”

include any such additional or other offices or agencies, as applicable.

The Company hereby initially

designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office

or agency in the contiguous United States of America where Notes may be surrendered for registration of transfer or exchange or for presentation

for payment or repurchase or for conversion and where notices and demands to or upon the Company in respect of the Notes and this Indenture

may be served; provided, however, that the Trustee shall not be deemed an agent of the Company for service of legal process.

Section 4.03. Appointments

to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of the Trustee,

will appoint, in the manner provided in ‎Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04. Provisions

as to Paying Agent. (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying

Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions

of this ‎Section 4.04:

(i)            that

it will hold all sums held by it as such agent for the payment of the principal (including the Redemption Price and the Fundamental Change

Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest or interest payable pursuant to Section 2.03(c) on,

the Notes in trust for the benefit of the Holders of the Notes;

(ii)            that

it will give the Trustee prompt written notice of any failure by the Company to make any payment of the principal (including the Redemption

Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest on, the Notes when

the same shall be due and payable; and

(iii)            that

at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums

so held in trust.

The Company shall, on or

before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of,

or any accrued and unpaid Special Interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including

the Redemption Price and the Fundamental Change Repurchase Price, if applicable) or any such accrued and unpaid Special Interest, and

(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided

that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on

such date.

(b)            If

the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and

the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid Special Interest on, the Notes, set aside, segregate

and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price

and the Fundamental Change Repurchase Price, if applicable) and any such accrued and unpaid Special Interest so becoming due and will

promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the

principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or any accrued and unpaid Special

Interest on, the Notes when the same shall become due and payable.

in this ‎Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction

and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in

trust by the Company or any Paying Agent hereunder as required by this ‎Section 4.04, such sums or amounts to be held by the

Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company

or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

(d)            Subject

to applicable escheatment laws, any money and shares of Common Stock deposited with the Trustee or any Paying Agent, or then held by

the Company, in trust for the payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if

applicable) of, any accrued and unpaid Special Interest or interest payable pursuant to Section 2.03(c) on and the consideration

due upon conversion of any Note and remaining unclaimed for two years after such principal (including the Redemption Price and the Fundamental

Change Repurchase Price, if applicable), Special Interest or interest payable pursuant to Section 2.03(c), if any, or consideration

due upon conversion has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s

Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an

unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with

respect to such trust money and shares of Common Stock, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 4.05. Existence.

Subject to ‎Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and

effect its corporate existence.

Section 4.06. Rule 144A

Information Requirement and Annual Reports. (a) At any time the Company is not subject to Section 13 or 15(d) of the

Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at

such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly

provide to the Trustee and, upon written request, any Holder, beneficial owner or prospective purchaser of such Notes or any shares of

Common Stock issuable upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under

the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A. The Company shall take

such further action as any Holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time

to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A,

as such rule may be amended from time to time.

(b)            The

Company shall furnish to the Trustee, within 15 days after the same are required to be filed with the Commission (after giving effect

to any grace period provided by Rule 12b-25 (or any successor rule), which grace period, for the avoidance of doubt, shall be deemed

applicable whether or not the Company checks the box in the relevant Rule 12b-25 filing indicating that the Company expects to file

such report within the applicable Rule 12b-25 grace period), copies of any documents or reports that the Company is required to

file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (excluding any such information, documents or

reports or portions thereof subject to confidential treatment and any correspondence with the Commission). Any such document or report

that the Company files with the Commission via the Commission’s EDGAR system (or any successor system) shall be deemed to be delivered

to the Trustee for purposes of this ‎Section 4.06(b) at the time such documents are filed via the EDGAR system (or any

successor system), it being understood that the Trustee shall not be responsible for determining whether such filings have been made.

Trustee shall have no duty to review or analyze reports described in subsection ‎(b) above delivered to it. Delivery of the

reports and documents described in subsection ‎(b) above to the Trustee is for informational purposes only, and the Trustee’s

receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein, or determinable

from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee

is entitled to rely exclusively on an Officer’s Certificate). The Trustee shall have no duty to monitor or confirm, on a continuing

basis or otherwise, the Company’s or any other Person’s compliance with any of the covenants hereunder to determine whether

any such reports, information or documents are available on the Commission’s website, the Company’s website or otherwise,

to examine such reports, information, documents and other reports to ensure compliance with the provisions herein, to ascertain the correctness

or otherwise of the information or the statements contained therein or to participate in any conference calls. Notwithstanding anything

to the contrary herein, the Trustee shall have no duty to search for or obtain any electronic or other filings that the Company makes

with the Commission, regardless of whether such filings are periodic, supplemental or otherwise.

(d)            If,

at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance

of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13

or 15(d) of the Exchange Act, as applicable (other than reports on Form 8-K and after giving effect to all applicable grace

periods thereunder including any grace period provided by Rule 12b-25 (or any successor rule), which grace period, for the avoidance

of doubt, shall be deemed applicable whether or not the Company checks the box in the relevant Rule 12b-25 filing indicating that

the Company expects to file such report within the applicable Rule 12b-25 grace period), or the Notes are not otherwise freely tradable

pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at

any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of

this Indenture or the Notes), the Company shall pay Special Interest on the Notes. Such Special Interest shall accrue on the Notes at

the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s

failure to file has occurred and is continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other

than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately

preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes. As used in this Section 4.06(d),

documents or reports that the Company is required to “file” with the Commission pursuant to Section 13 or 15(d) of

the Exchange Act do not include documents or reports that the Company furnishes to the Commission pursuant to Section 13 or 15(d) of

the Exchange Act.

(e)            If,

and for so long as, the restrictive legend on the Notes specified in ‎Section 2.05(c) has not been removed, the Notes are

assigned a restricted CUSIP number or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the

Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding

(without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the De-Legending Deadline Date

for such Notes, the Company shall pay Special Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes

outstanding for each day from, and including, such De-Legending Deadline Date until the restrictive legend on the Notes has been removed

in accordance with ‎Section 2.05(c), the Notes are assigned an unrestricted CUSIP number and the Notes are freely tradable pursuant

to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time

during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or

the Notes; provided, however, that no such Special Interest shall accrue or be owed until the fifth Business Day following written

notification to the Company by the Trustee or any Holder or beneficial owner of the Notes (with a copy to the Trustee) requesting that

the Company complies with its obligations described in this clause (e) (which notice may be given at any time after the 330th day

after the last date of original issuance of the Notes), it being understood and agreed that in no event shall such Special Interest accrue

or be owed for any period prior to the De-Legending Deadline Date for such Notes.

(f)            Special

Interest will be payable in arrears on each Special Interest Payment Date following accrual as set forth in Section 2.03(b); provided

that if Special Interest begins to accrue pursuant to ‎Section 4.06(d) after the close of business on a Special Interest

Record Date and prior to the open of business on the corresponding Special Interest Payment Date, the Special Interest that accrues during

such period shall be due on the Special Interest Payment Date next succeeding such corresponding Special Interest Payment Date, and no

Special Interest shall accrue in respect of such delay.

(g)            The

Special Interest that is payable in accordance with Section 4.06‎(d) or Section 4.06‎(e) shall be in addition

to, and not in lieu of, any Special Interest that may be payable as a result of the Company’s election pursuant to ‎Section 6.03;

provided that in no event shall any Special Interest that may accrue pursuant to ‎Section 4.06(d) as a result of

the Company’s failure to timely file any document or report that the Company is required to file with the Commission pursuant to

Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and

other than reports on Form 8-K), together with any Special Interest payable at the Company’s election pursuant to ‎Section 6.03

as a remedy for a Reporting Event of Default, accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of

the number of events or circumstances giving rise to the requirement to pay such Special Interest.

(h)            If

Special Interest is payable by the Company pursuant to Section 4.06‎(d) or Section 4.06‎(e), the Company shall

deliver to the Trustee an Officer’s Certificate to that effect stating (i) the amount of such Special Interest that is payable

and (ii) the date on which such Special Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the

Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Special Interest is payable. If the Company

has paid Special Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate

setting forth the particulars of such payment.

Section 4.07. Stay,

Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon,

plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would

prohibit or forgive the Company from paying all or any portion of the principal of or any Special Interest or interest payable pursuant

to Section 2.03(c) on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may

affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives

all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution

of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been

enacted.

Section 4.08. Compliance

Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year

of the Company (beginning with the fiscal year ending on December 31, 2026) an Officer’s Certificate stating whether the signers

thereof have knowledge of any Event of Default hereunder and, if so, specifying each such Event of Default and the nature thereof.

addition, the Company shall deliver to the Trustee, as soon as possible, and in any event within 30 days after the occurrence of any

Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status

and the action that the Company is taking or proposing to take in respect thereof; provided,

however, that the Company shall not be required to deliver such Officer’s Certificate if such Event of Default or Default, as applicable,

has been cured or waived within the applicable grace period, if any, as set forth herein.

Section 4.09. Further

Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further

acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

Article 5

Lists of Holders and Reports by the Company and the Trustee

Section 5.01. Lists

of Holders. The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually, not more

than 15 days after each May 1 and November 1 in each year beginning with November 1, 2026, and at such other times as

the Trustee may request in writing, within 30 days after receipt by the Company of any such request (or such lesser time as the Trustee

may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the

Trustee may reasonably require of the names and addresses of the Holders as of a date not more than 15 days (or such other date as the

Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that

no such list need be furnished so long as the Trustee is acting as Note Registrar.

Section 5.02. Preservation

and Disclosure of Lists. The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the

names and addresses of the Holders contained in the most recent list furnished to it as provided in ‎Section 5.01 or maintained

by the Trustee in its capacity as Note Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in ‎Section 5.01

upon receipt of a new list so furnished.

Article 6

Defaults and Remedies

Section 6.01. Events

of Default. Each of the following events shall be an “Event of Default” with respect to the Notes:

of the Notes then outstanding to the Company and the Trustee has been received by the Company to comply with any of its other agreements

contained in the Notes or this Indenture;

(g)            default

by the Company or any Significant Subsidiary with respect to any mortgage, agreement or other instrument under which there may be outstanding,

or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $75,000,000 (or its foreign currency

equivalent) in the aggregate of the Company and/or any such Significant Subsidiary, whether such indebtedness now exists or shall hereafter

be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity date or (ii) constituting

a failure to pay the principal or interest of any such debt when due and payable (after the expiration of all applicable grace periods)

at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and in the cases of clauses (i) and

(ii), such acceleration shall not have been rescinded or annulled or such failure to pay or default shall not have been cured or waived,

or such indebtedness is not paid or discharged, as the case may be, within 30 days after written notice to the Company by the Trustee

or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined

in accordance with ‎Section 8.04;

(h)            the

Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other

relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar

law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of

the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the

appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make

a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due; or

(i)            an

involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation, reorganization

or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar

law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of

the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case or other proceeding shall

remain undismissed and unstayed for a period of 30 consecutive days.

Section 6.02. Acceleration;

Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event

of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or

order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such

case (other than an Event of Default specified in ‎Section 6.01(h) or ‎Section 6.01(i) with respect to the

Company or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable,

either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance

with ‎Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal

of, and accrued and unpaid Special Interest, if any, on, all the Notes to be due and payable immediately, and upon any such declaration

the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to

the contrary notwithstanding. If an Event of Default specified in ‎Section 6.01(h) or ‎Section 6.01(i) with

respect to the Company or any of its Significant Subsidiaries occurs and is continuing, 100% of the principal of, and accrued and unpaid

Special Interest, if any, on, all Notes shall become and shall automatically be immediately due and payable.

The

immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have

been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered

as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and

unpaid Special Interest, if any, upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration

(with no interest accruing on such overdue principal or installments of accrued and unpaid Special Interest unless Special Interest

was payable pursuant to this Indenture on the required payment date, in which case such overdue amounts shall accrue interest per annum

at the then-applicable Special Interest rate borne by the Notes, to the extent that payment of such interest is enforceable under applicable

law, from, and including such required payment date) and amounts due to the Trustee pursuant to ‎Section 7.06, and if (1) rescission

would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default

under this Indenture, other than the nonpayment of the principal of and accrued and unpaid Special Interest, if any, on Notes that shall

have become due solely by such acceleration, shall have been cured or waived pursuant to ‎Section 6.09, then and in every such

case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes

then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the

Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising

therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall

extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything

to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting

from (i) the nonpayment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable)

of, or accrued and unpaid Special Interest, if any, on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a

failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

For the avoidance of doubt,

and without limiting the manner in which any Default or Event of Default can be cured, (a) a failure by the Company to send a notice

in accordance with this Indenture and any related Default (or Event of Default) shall be deemed cured and shall cease to continue upon

delivery of such notice to the applicable recipient; (b) if the Company fails to make any payment of principal of or Special Interest,

if any, on the Notes (or delivery of any other consideration in respect thereof) when due, such Default (or Event of Default) shall be

deemed cured and shall cease to continue upon the making of such payment or delivery, as applicable, together with any accrued Special

Interest thereon, if applicable; and (c) a Reporting Event of Default shall be deemed cured and shall cease to continue at such

time as the Company files the applicable report or reports that gave rise to such Reporting Event of Default (it being understood that

any report that the Company files with the Commission through the EDGAR system (or any successor thereto) shall be deemed to be filed

with the Trustee at the time such report is so filed via the EDGAR system (or such successor)); provided that, for the avoidance

of doubt, (x) the cure of any Event of Default shall not invalidate any acceleration of the Notes on account of such Event of Default

that was properly effected prior to such time as such Event of Default was cured and (y) the cure of any Reporting Event of Default

shall not affect the Company’s obligation to pay any Special Interest that accrued prior to the time of such cure. If an Event

of Default is cured or waived before any related notice of acceleration is delivered, such Event of Default shall be deemed cured and

the Notes shall not be subject to acceleration on account of such Event of Default. For the avoidance of doubt, nothing in the immediately

preceding two sentences shall constitute a waiver of, or in any way limit the Trustee’s or any Holder’s right to institute

suit for, any damages incurred as a result of the Company’s breach of any covenant under this Indenture, even if such breach is

subsequently cured.

Section 6.03.

Special Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects,

the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in ‎Section 4.06(b) (a

“Reporting Event of Default”) shall (i) for the first 90 days after the occurrence of such an Event of Default

(which, for the avoidance of doubt, shall not commence until the notice described in ‎Section 6.01(f) above

has been given, and the related 60-day period described in ‎Section 6.01(f) above

has passed) consist exclusively of the right to receive Special Interest on the Notes at a rate equal to 0.25% per annum of the principal

amount of the Notes outstanding for each day during such 90-day period on which such an Event of Default is continuing and (ii) for

the period from, and including, the 91st day after the occurrence of such an Event of Default to, and including, the 270th day after

the occurrence of such an Event of Default, consist exclusively of the right to receive Special Interest on the Notes at a rate equal

to 0.50% per annum of the principal amount of the Notes outstanding for each day during such additional 180-day period on which such

an Event of Default is continuing. Special Interest payable pursuant to this ‎Section 6.03 shall be in addition to, not in lieu

of, any Special Interest payable pursuant to ‎Section 4.06(d) or ‎Section 4.06(e) (subject to the last paragraph

of this ‎Section 6.03). If the Company so elects, such Special Interest shall be payable as set forth in Section 2.03(b).

On the 271st day after a Reporting Event of Default (if the Reporting Event of Default is not cured or waived prior to such 271st day),

the Notes shall be immediately subject to acceleration as provided in ‎Section 6.02. The provisions of this Section 6.03

will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than a Reporting Event of

Default. In the event the Company does not elect to pay Special Interest following a Reporting Event of Default in accordance with this

‎Section 6.03 or the Company elected to make such payment but does not pay the Special Interest when due, the Notes shall be

immediately subject to acceleration as provided in ‎Section 6.02.

order to elect to pay Special Interest as the sole remedy during the first 270 days after the occurrence of any Reporting Event of Default

in accordance with the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying

Agent of such election prior to the beginning of such 270-day period (which, for the avoidance of doubt, shall not commence until

the notice described in ‎Section 6.01(f) above has been given, and the related 60-day

period described in ‎Section 6.01(f) above has passed). Upon the failure to timely

give such notice, the Notes shall be immediately subject to acceleration as provided in ‎Section 6.02.

In no event shall Special

Interest payable at the Company’s election as a remedy for a Reporting Event of Default as set forth in this Section 6.03,

together with any Special Interest that may accrue as a result of the Company’s failure to timely file any document or report that

the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after

giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), pursuant to Section 4.06(d),

accrue at a rate in excess of 0.50% per annum pursuant to this Indenture, regardless of the number of events or circumstances giving

rise to the requirement to pay such Special Interest.

Section 6.04.

Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause ‎(a) or ‎(b) of ‎Section 6.01

shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes,

the whole amount then due and payable on the Notes for principal and Special Interest, if any (with no interest accruing on any

overdue principal or Special Interest unless Special Interest was payable pursuant to this Indenture on the required payment date, in

which case such overdue amounts shall accrue interest per annum at the then-applicable Special Interest rate borne by the Notes, subject

to the enforceability thereof under applicable law, from, and including, such required payment date) and, in addition thereto, such further

amount as shall be sufficient to cover any amounts due to the Trustee under ‎Section 7.06. If the Company shall fail to pay

such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding

for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same

against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided

by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall

be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of

the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator,

sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property

of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor

upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal

of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee

shall have made any demand pursuant to the provisions of this ‎Section 6.04, shall be entitled and empowered, by intervention

in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid Special

Interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or

documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including

any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders

allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their

property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same

after the deduction of any amounts due to the Trustee under ‎Section 7.06; and any receiver, assignee or trustee in bankruptcy

or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the

Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the

Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents

and counsel fees, and including any other amounts due to the Trustee under ‎Section 7.06, incurred by it up to the date of such

distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any

such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and

all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such

proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

Nothing herein contained

shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,

arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote

in respect of the claim of any Holder in any such proceeding.

All rights of action and

of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of

the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by

the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for

the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable

benefit of the Holders of the Notes.

In any proceedings brought

by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be

a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the

Notes parties to any such proceedings.

In case the Trustee shall

have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any

waiver pursuant to ‎Section 6.09 or any rescission and annulment pursuant to ‎Section 6.02 or for any other reason

or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject

to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies

and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.05. Application

of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this ‎Article 6 with respect to the Notes

shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation

of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First,

to the payment of all amounts due the Trustee, including its agents and counsel, under ‎Section 7.06;

Second,

in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any Special Interest on, and

any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such Special Interest and cash

due upon conversion, as the case may be, with interest (to the extent that any such interest is payable on such Notes and has been collected

by the Trustee) upon such overdue payments at the rate of Special Interest then payable on such Notes, if any, such payments to be made

ratably to the Persons entitled thereto;

Third,

in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the

whole amount (including, if applicable, the payment of the Redemption Price, the Fundamental Change Repurchase Price and any cash due

upon conversion) then owing and unpaid upon the Notes for principal and Special Interest, if any, with interest (to the extent that any

such interest is payable on such Notes and has been collected by the Trustee) on the overdue principal and Special Interest, if any,

at the rate of Special Interest then payable on such Notes, if any, and in case such monies shall be insufficient to pay in full the

whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Redemption Price,

the Fundamental Change Repurchase Price and any cash due upon conversion) and such Special Interest, if any, and such interest on overdue

principal and Special Interest, if any, without preference or priority of principal over any such interest, or of any such interest over

principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the

aggregate of such principal (including, if applicable, the Redemption Price, the Fundamental Change Repurchase Price and any cash due

upon conversion) and any accrued and unpaid interest; and

Fourth,

to the payment of the remainder, if any, to the Company.

Section 6.06. Proceedings

by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price and the Fundamental

Change Repurchase Price) or any Special Interest when due, or the right to receive payment or delivery of the consideration due upon

conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any

suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver,

trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a)           such

Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b)           Holders

of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute

such action, suit or proceeding in its own name as Trustee hereunder;

Holders shall have offered to the Trustee such security or indemnity satisfactory to it against any loss, liability or expense to be

incurred therein or thereby;

(d)           the

Trustee for 60 days after its receipt of such notice, request and offer of such security or indemnity, shall have neglected or refused

to institute any such action, suit or proceeding; and

(e)           no

direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the

Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to ‎Section 6.09,

it being understood and intended, and being expressly

covenanted by the taker and Holder of every Note with every other taker and Holder that no one or more Holders shall have any right in

any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any

other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this

Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided

herein). For the protection and enforcement of this ‎Section 6.06, each and every Holder and the Trustee shall be entitled to

such relief as can be given either at law or in equity.

Notwithstanding any other

provision of this Indenture and any provision of any Note, each Holder shall have the right to receive payment or delivery, as the case

may be, of (x) the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued

and unpaid Special Interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective

due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or

delivery, as the case may be.

Section 6.07. Proceedings

by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in

it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit

in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement

contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable

right vested in the Trustee by this Indenture or by law. The Trustee may maintain a proceeding even if it does not possess the Notes

or does not produce the Notes in a proceeding.

Section 6.08. Remedies

Cumulative and Continuing. Except as provided in the last paragraph of ‎Section 2.06, all powers and remedies given by this

‎Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of

any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise,

to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the

Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair

any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and,

subject to the provisions of ‎Section 6.06, every power and remedy given by this ‎Article 6 or by law to the Trustee

or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.09. Direction

of Proceedings and Waiver of Defaults by Majority of Holders. The Holders of a majority of the aggregate principal amount of the

Notes at the time outstanding determined in accordance with ‎Section 8.04 shall have the right to direct the time, method and

place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee

with respect to the Notes; provided, however, that (a) such direction shall not be in conflict with any rule of

law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent

with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other

Holder or that would involve the Trustee in personal liability; provided that the Trustee shall not have an affirmative duty to

determine whether any such direction is prejudicial to any other Holder. The Holders of a majority in aggregate principal amount of the

Notes at the time outstanding determined in accordance with ‎Section 8.04 may on behalf of the Holders of all of the Notes waive

any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid Special

Interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of, the Notes when

due that has not been cured pursuant to the provisions of ‎Section 6.01, (ii) a failure by the Company to pay or deliver,

as the case may be, the consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision

hereof which under ‎Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected.

Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder;

but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever

any Default or Event of Default hereunder shall have been waived as permitted by this ‎Section 6.09, said Default or Event of

Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver

shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10. Notice

of Defaults. If a Default occurs and is continuing and a Responsible Officer of the Trustee is notified in writing or has actual

knowledge of such Default, in each case as provided in Section 7.02(l) hereof, the Trustee shall deliver to each Holder notice

of the Default within 90 days after a Responsible Officer of the Trustee receives such written notice or obtains actual knowledge thereof,

unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a

Default in the payment of the principal of (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable),

or any accrued and unpaid Special Interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon

conversion, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee in good

faith determines that the withholding of such notice is in the interests of the Holders.

Section 6.11. Undertaking

to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have

agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture,

or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of

an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable

attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims

or defenses made by such party litigant; provided that the provisions of this ‎Section 6.11 (to the extent permitted

by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in

the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with ‎Section 8.04,

or to any suit instituted by any Holder for the enforcement of the payment of the principal of or any accrued and unpaid Special Interest

or interest payable pursuant to Section 2.03(c) on any Note (including, but not limited to, the Redemption Price and the Fundamental

Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement

of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of ‎Article 14.

Article 7

Concerning the Trustee

Section 7.01. Duties

and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all

Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this

Indenture. In the event an Event of Default has occurred and is continuing of which a Responsible Officer has written notice or actual

knowledge, in each case as provided in Section 7.02(l) hereof, the Trustee shall exercise such of the rights and powers vested

in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the

circumstances in the conduct of such person’s own affairs. The Trustee will be under no obligation to exercise any of the rights

or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity

or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or

direction.

No provision of this Indenture

shall be construed to relieve the Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act

or its own willful misconduct, except that:

(a)           prior

to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

(i)            the

duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not

be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants

or obligations shall be read into this Indenture against the Trustee; and

(ii)           in

the absence of gross negligence or willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth

of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and

conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof

are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether

or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations

or other facts stated therein);

(b)           the

Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless

it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction

of the Holders of not less than a majority of the aggregate principal amount of the Notes at the time outstanding determined as provided

in ‎Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee,

or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d)           whether

or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection

to, the Trustee shall be subject to the provisions of this Section and ‎Section 7.02;

(e)           the

Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating

to payment) or notice effected by the Company or any Paying Agent or any records maintained by any co-Note Registrar with respect to

the Notes;

(f)            if

any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to

the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred;

(g)           in

the absence of written investment direction from the Company, all cash received by the Trustee shall be placed in a non-interest bearing

trust account, and shall be held uninvested; and

(h)           in

the event that the Trustee is also acting as Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer

agent hereunder, the rights and protections afforded to the Trustee pursuant to this ‎Article 7 shall also be afforded to such

Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or transfer agent; provided that during an Event

of Default, only the Trustee and not any of the Custodian, Note Registrar, Paying Agent, Conversion Agent, Bid Solicitation Agent or

transfer agent, shall be subject to the prudent person standard.

None of the provisions contained

in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance

of any of its duties or in the exercise of any of its rights or powers.

Section 7.02. Reliance

on Documents, Opinions, Etc. Except as otherwise provided in ‎Section 7.01:

Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,

personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or

investigation;

Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder; and

be liable for any consequential loss or damage of any special, indirect, punitive, incidental or kind whatsoever (including but not limited

to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

The Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either (1) a

Responsible Officer shall have actual knowledge of such Default or Event of Default or (2) written notice of such Default or Event

of Default shall have been given to a Responsible Officer of the Trustee by the Company or by any Holder at the Corporate Trust Office

and such notice references the Notes, the Company and this Indenture and states that it is a notice of Default or Event of Default.

Section 7.03. No

Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication)

shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee

Paying Agents, Conversion Agents, Bid Solicitation Agent or Note Registrar May Own Notes. The Trustee, any Paying Agent, any

Conversion Agent, Custodian, Bid Solicitation Agent (if other than the Company or any Affiliate thereof) or Note Registrar, in its individual

Agent, Conversion Agent, Custodian, Bid Solicitation Agent or Note Registrar.

Section 7.05. Monies

and Shares of Common Stock to Be Held in Trust. All monies and shares of Common Stock received by the Trustee shall, until used or

applied as herein provided, be held in trust for the purposes for which they were received. Money and shares of Common Stock held by

the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under

no liability for interest on any money or shares of Common Stock received by it hereunder except as may be agreed from time to time by

the Company and the Trustee.

Section 7.06. Compensation

and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled

to, receive such compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision

of law in regard to the compensation of a trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company,

and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably

incurred or made by the Trustee in accordance with any of the provisions of this Indenture in any capacity hereunder (including the reasonable

compensation and the expenses and disbursements of its agents and counsel and of all Persons not regularly in its employ) except any

such expense, disbursement or advance as shall have been caused by its gross negligence or willful misconduct (as adjudicated in a final

non-appealable decision by a court of competent jurisdiction). The Company also covenants and agrees to indemnify, defend and protect

the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith and its agents

and any authenticating agent for, and to hold them harmless against, any loss, claim, damage, liability or expense, including taxes (other

than taxes based upon, measured by, or determined by the income of the Trustee) and attorneys’ fees, incurred without gross negligence

or willful misconduct on the part of the Trustee, its officers, directors, agents or employees, or such agent or authenticating agent,

as the case may be (as adjudicated in a final non-appealable decision by a court of competent jurisdiction), and arising out of or in

connection with the acceptance or administration of this Indenture and the enforcement of this Indenture (including this ‎Section 7.06)

or in any other capacity hereunder, including the costs and expenses (including attorneys’ fees) of defending themselves against

any claim of liability in the premises or enforcing the Company’s obligations hereunder (whether asserted by the Company, a Holder

or any other Person). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee

to so notify the Company shall not relieve the Company of its obligations hereunder. The Trustee may have one separate counsel, and the

Company shall pay the reasonable fees and expenses of such counsel for the Trustee. The obligations of the Company under this ‎Section 7.06

to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured

by a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by the Trustee, except, subject

to the effect of ‎Section 6.05, funds held in trust herewith for the benefit of the Holders of particular Notes. The Trustee’s

right to receive payment of any amounts due under this ‎Section 7.06 shall not be subordinate to any other liability or indebtedness

of the Company and to secure the Company’s payment obligations under this ‎Section 7.06, the Trustee shall have a lien

prior to the Notes on all money or property held or collected by the Trustee, in its capacity as the Trustee, other than money or property

held in trust to pay principal and Special Interest, if any, or interest pursuant to Section 2.03(c) on the Notes. The obligation

of the Company under this ‎Section 7.06 shall survive the satisfaction and discharge of this Indenture, final payment on the

Notes and the earlier resignation or removal of the Trustee. The Company need not pay for any settlement made without its consent, which

consent shall not be unreasonably withheld. The indemnification provided in this ‎Section 7.06 shall extend to the officers,

directors, agents and employees of the Trustee.

Without prejudice to any

other rights available to the Trustee under applicable law, when the Trustee and its agents and any authenticating agent incur expenses

or render services after an Event of Default specified in ‎Section 6.01(h) or ‎Section 6.01(i) occurs, the

expenses and the compensation for the services are intended to constitute expenses of administration for purposes of priority under any

bankruptcy, insolvency or similar laws.

Section 7.07. Officer’s

Certificate as Evidence. Except as otherwise provided in ‎Section 7.01, whenever in the administration of the provisions

of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting

any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively

proved and established by an Officer’s Certificate delivered to the Trustee, and such Officer’s Certificate shall be full

warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 7.08. Eligibility

of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust Indenture

Act (as if the Trust Indenture Act were applicable hereto) to act as such and has a combined capital and surplus of at least $50,000,000.

If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining

authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined

capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible

in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified

in this Article.

Section 7.09. Resignation

or Removal of Trustee. (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and

by delivering notice thereof to the Holders. Upon receiving such notice of resignation, the Company shall promptly appoint a successor

trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered

to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted

appointment within 30 days after the giving of such notice of resignation to the Holders, the resigning Trustee may, at the Company’s

expense, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment

of a successor trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months (or since the date of

this Indenture) may, subject to the provisions of ‎Section 6.11, on behalf of himself or herself and all others similarly situated,

petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem

proper and prescribe, appoint a successor trustee. At any time at which no Event of Default has occurred and is continuing, the Company

may by a Board Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of

the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee.

(b)           In

case at any time any of the following shall occur:

(i)            the

Trustee shall cease to be eligible in accordance with the provisions of ‎Section 7.08 and shall fail to resign after written

request therefor by the Company or by any such Holder, or

(ii)           the

Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property

shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of

rehabilitation, conservation or liquidation,

then, in either case, the Company may by a Board

Resolution remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of

Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject

to the provisions of ‎Section 6.11, any Holder who has been a bona fide holder of a Note or Notes for at least six months (or

since the date of this Indenture) may, on behalf of himself or herself and all others similarly situated, petition any court of competent

jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice,

if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

Holders of a majority in aggregate principal amount of the Notes at the time outstanding, as determined in accordance with ‎Section 8.04,

may at any time, upon 30 days’ prior written notice to the Trustee and the Company, remove the Trustee and nominate a successor

trustee that shall be deemed appointed as successor trustee unless within ten days after notice to the Company of such nomination the

Company objects thereto, in which case the Trustee so removed (at the Company’s expense) or any Holder, upon the terms and conditions

and otherwise as in ‎Section 7.09(a) provided, may petition any court of competent jurisdiction for an appointment of a

successor trustee.

(d)           Any

resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this ‎Section 7.09

shall become effective upon (i) payment of all fees and expenses owing to the Trustee and (ii) acceptance of appointment by

the successor trustee as provided in ‎Section 7.10.

Section 7.10. Acceptance

by Successor Trustee. Any successor trustee appointed as provided in ‎Section 7.09 shall execute, acknowledge and deliver

to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal

of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become

vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee

herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon

payment of any amounts then due it pursuant to the provisions of ‎Section 7.06, execute and deliver an instrument transferring

to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the

Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee

all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made

subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders

of particular Notes, to secure any amounts then due it pursuant to the provisions of ‎Section 7.06.

No successor trustee shall

accept appointment as provided in this ‎Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible

under the provisions of ‎Section 7.08.

Upon acceptance of appointment

by a successor trustee as provided in this ‎Section 7.10, each of the Company and the successor trustee, at the written direction

and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders.

If the Company fails to deliver such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee

shall cause such notice to be delivered at the expense of the Company.

Section 7.11. Succession

by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with which it may be consolidated,

or any corporation or other entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any

corporation or other entity succeeding to all or substantially all of the corporate trust business of the Trustee (including the administration

of this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on

the part of any of the parties hereto; provided that in the case of any corporation or other entity succeeding to all or substantially

all of the corporate trust business of the Trustee such corporation or other entity shall be eligible under the provisions of ‎Section 7.08.

In case at the time such

successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not

delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating

agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall

not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate

such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such

certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee

shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor trustee or

to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or

consolidation.

Section 7.12. Trustee’s

Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than

with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes

under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee

under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall

not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after

the date specified in such application (which date shall not be less than three Business Days after the date any Officer that the Company

has indicated to the Trustee should receive such application actually receives such application, unless any such Officer shall have consented

in writing to any earlier date), unless, prior to taking any such action (or the effective date in the case of any omission), the Trustee

shall have received written instructions in accordance with this Indenture in response to such application specifying the action to be

taken or omitted.

Article 8

Concerning the Holders

Section 8.01. Action

by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage of the aggregate principal amount

of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking

of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein

may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or

proxy appointed in writing, or (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and

held in accordance with the provisions of ‎Article 9, or (c) by a combination of such instrument or instruments and any

such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the

Notes, the Company or the Trustee may, but shall not be required to, fix in advance of such solicitation, a date as the record date for

determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen days prior to the

date of commencement of solicitation of such action.

Section 8.02. Proof

of Execution by Holders. Subject to the provisions of ‎Section 7.01, ‎Section 7.02 and ‎Section 9.05,

proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable

rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding

of Notes shall be proved by the Note Register or by a certificate of the Note Registrar. The record of any Holders’ meeting shall

be proved in the manner provided in ‎Section 9.06.

Section 8.03. Who

Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note

Registrar may deem the Person in whose name a Note shall be registered upon the Note Register to be, and may treat it as, the absolute

owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon

made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal

(including any Redemption Price and any Fundamental Change Repurchase Price) of and (subject to ‎Section 2.03) any accrued and

unpaid Special Interest or interest payable pursuant to Section 2.03(c) on such Note, for conversion of such Note and for all

other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor any Note Registrar shall be

affected by any notice to the contrary. The sole registered holder of a Global Note shall be the Depositary or its nominee. All such

payments or deliveries so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sums or

shares of Common Stock so paid or delivered, effectual to satisfy and discharge the liability for monies payable or shares deliverable

upon any such Note. Notwithstanding anything to the contrary in this Indenture or the Notes following an Event of Default, any holder

of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization

or any other action of the Depositary or any other Person, such holder’s right to exchange such beneficial interest for a Note

in certificated form in accordance with the provisions of this Indenture.

Section 8.04. Company-Owned

Notes Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any

direction, consent, waiver or other action under this Indenture, Notes that are owned by the Company, by any Subsidiary thereof or by

any Affiliate of the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such

determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction,

consent, waiver or other action only Notes that a Responsible Officer actually knows are so owned shall be so disregarded. Notes so owned

that have been pledged in good faith may be regarded as outstanding for the purposes of this ‎Section 8.04 if the pledgee shall

establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not

the Company, a Subsidiary thereof or an Affiliate of the Company or a Subsidiary thereof. In the case of a dispute as to such right,

any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the

Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the

Company to be owned or held by or for the account of any of the above described Persons; and, subject to ‎Section 7.01, the

Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the

fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation

of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in ‎Section 8.01,

of the taking of any action by the Holders of the percentage of the aggregate principal amount of the Notes specified in this Indenture

in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have

consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided

in ‎Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder

of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued

in exchange or substitution therefor or upon registration of transfer thereof, irrespective of whether any notation in regard thereto

is made upon such Note or any Note issued in exchange or substitution therefor or upon registration of transfer thereof.

Such notices shall be delivered not less than 20 nor more than 90 days prior to the date fixed for the meeting.

notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the

place for such meeting and may call such meeting to take any action authorized in ‎Section 9.01, by delivering notice thereof

as provided in ‎Section 9.02.

the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating

it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of ‎Section 9.02

or ‎Section 9.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Notes

the latter to have attached thereto the ballots voted at the meeting.

Any record so signed and

at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto for one

or more of the following purposes:

(a)           to

cure any ambiguity, omission, defect or inconsistency;

secure the Notes;

(e)           to

add to the covenants or Events of Default of the Company for the benefit of the Holders or surrender any right or power conferred upon

(f)            to

make any change that does not adversely affect the rights of any Holder in any material respect;

(g)           to

(i)            to

provide for the issuance of additional Notes in accordance this Indenture;

(j)            in

connection with any Share Exchange Event, to provide that the Notes are convertible into Reference Property, subject to the provisions

of ‎Section 14.02, and make such related changes to the terms of the Notes to the extent expressly required by ‎Section 14.07;

(k)           to

conform the provisions of this Indenture or the Notes to the “Description of Notes” section of the Offering Memorandum.

Upon the written request

of the Company, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make

any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to, but may

in its discretion, enter into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this

Indenture or otherwise.

Any supplemental indenture

authorized by the provisions of this ‎Section 10.01 may be executed by the Company and the Trustee without the consent of the

Holders of any of the Notes at the time outstanding, notwithstanding any of the provisions of ‎Section 10.02.

Section 10.02. Supplemental

Indentures with Consent of Holders. With the consent (evidenced as provided in ‎Article 8) of the Holders of at least a

majority of the aggregate principal amount of the Notes then outstanding (determined in accordance with ‎Article 8 and including,

without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when

authorized by the resolutions of the Board of Directors, and the Trustee, at the Company’s expense, may from time to time and at

any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner

or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the

Holders; provided, however, that, without the consent of each Holder of an outstanding Note affected, no such supplemental

indenture shall:

(a)           reduce

the amount of Notes whose Holders must consent to an amendment;

(b)           reduce

the rate of or extend the stated time for payment of Special Interest or interest payable pursuant to Section 2.03(c) on any

Note;

(d)           make

any change that adversely affects the conversion rights of any Notes;

(e)           reduce

Company’s obligation to make such payments, whether through an amendment or waiver of provisions in the covenants, definitions

or otherwise;

(f)            make

any Note payable in a currency, or at a place of payment, other than that stated in the Note;

(g)           change

the ranking of the Notes; or

(h)           make

any change in this ‎Article 10 that requires each Holder’s consent or in the waiver provisions in ‎Section 6.02

or ‎Section 6.09.

Upon the written request

of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to ‎Section 10.05,

the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the

Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,

but shall not be obligated to, enter into such supplemental indenture.

Holders do not need under

this ‎Section 10.02 to approve the particular form of any proposed supplemental indenture. It shall be sufficient if such Holders

approve the substance thereof. After any such supplemental indenture becomes effective, the Company shall deliver to the Holders (with

a copy to the Trustee) a notice briefly describing such supplemental indenture. However, the failure to give such notice to all the Holders,

or any defect in the notice, will not impair or affect the validity of the supplemental indenture.

Section 10.03. Effect

of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this ‎Article 10,

this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights,

obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised

and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such supplemental

indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 10.04. Notation

on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this

‎Article 10 may, at the Company’s expense, bear a notation as to any matter provided for in such supplemental indenture.

If the Company or the Trustee shall so determine, new Notes so modified as to conform to any modification of this Indenture contained

in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the

Trustee (or an authenticating agent duly appointed by the Trustee pursuant to ‎Section 17.10) and delivered in exchange for

the Notes then outstanding, upon surrender of such Notes then outstanding.

Section 10.05. Evidence

of Compliance of Supplemental Indenture to Be Furnished Trustee. In addition to the documents required by ‎Section 17.05,

the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture

executed pursuant hereto complies with the requirements of this ‎Article 10 and is permitted or authorized by this Indenture.

Article 11

Consolidation, Merger, Sale, Conveyance and Lease

Section 11.01. Company

May Consolidate, Etc. on Certain Terms. Subject to the provisions of ‎Section 11.02, the Company shall not consolidate

with, merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person

(each, a “Business Combination Event”), unless:

(a)           the

resulting, surviving or transferee Person, if not the Company, shall be a Qualified Successor Entity (such Qualified Successor Entity,

the “Successor Entity”) organized and existing under the laws of the United States of America, any State thereof or

the District of Columbia, and the Successor Entity (if not the Company) shall expressly assume, by supplemental indenture all of the

obligations of the Company under the Notes and this Indenture;

(b)           immediately

after giving effect to such Business Combination Event, no Default or Event of Default shall have occurred and be continuing under this

Indenture; and

Company has delivered to the Trustee an Officer’s Certificate and Opinion of Counsel stating that all conditions precedent to such

Business Combination Event and such supplemental indenture (if any) have been complied with and that such Business Combination Event

and such supplemental indenture (if any) complies with the provisions of this Indenture.

For purposes of this ‎Section 11.01,

the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company

to another Person, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially

all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease

of all or substantially all of the properties and assets of the Company to another Person.

Section 11.02. Successor

Corporation to Be Substituted. In case of any Business Combination Event and upon the assumption by the Successor Entity, by supplemental

indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal

of and Special Interest, if any, on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration

due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be

performed by the Company, such Successor Entity (if not the Company) shall succeed to and, except in the case of a lease of all or substantially

all of the Company’s properties and assets, shall be substituted for the Company, with the same effect as if it had been named

herein as the party of the first part. Such Successor Entity thereupon may cause to be signed, and may issue either in its own name or

in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and

delivered to the Trustee; and, upon the order of such Successor Entity instead of the Company and subject to all the terms, conditions

and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered,

any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and

any Notes that such Successor Entity thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes

so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued

in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the

event of any Business Combination Event (but not in the case of a lease), upon compliance with this ‎Article 11 the Person named

as the “Company” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the

manner prescribed in this ‎Article 11) may be dissolved, wound up and liquidated at any time thereafter and, except in the case

of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this

Indenture and the Notes.

In case of any Business Combination

Event, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 11.03. Opinion

of Counsel to Be Given to Trustee. No Business Combination Event shall be effective unless the Trustee shall receive an Officer’s

Certificate and an Opinion of Counsel as set forth in ‎Section 11.01(c).

Article 12

Immunity of Incorporators, Stockholders, Officers and Directors

Section 12.01. Indenture

and Notes Solely Corporate Obligations. No recourse for the payment of the principal of or any accrued and unpaid Special Interest

on any Note, nor for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant

or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, nor because of the creation of any indebtedness

represented thereby, shall be had against any incorporator, stockholder, employee, agent, Officer or director or Subsidiary, as such,

past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation,

whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise;

it being expressly understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration

for, the execution of this Indenture and the issue of the Notes.

Article 13

[Intentionally Omitted]

Article 14

Conversion of Notes

Section 14.01. Conversion

Privilege. (a) Subject to and upon compliance with the provisions of this ‎Article 14, each Holder shall have the right,

at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral

multiple thereof) of such Note (i) subject to satisfaction of the conditions described in ‎Section 14.01(b), at any time

prior to the close of business on the Business Day immediately preceding February 15, 2031 under the circumstances and during the

periods set forth in ‎Section 14.01(b), and (ii) regardless of the conditions described in ‎Section 14.01(b),

on or after February 15, 2031 and prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity

Date, in each case, at an initial conversion rate of 1.9655 shares of Common Stock (subject to adjustment as provided in this ‎Article 14,

the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions

of ‎Section 14.02, the “Conversion Obligation”).

(b)           (i) Prior

to the close of business on the Business Day immediately preceding February 15, 2031, a Holder may surrender all or any portion

of its Notes (that is at least $1,000 aggregate principal amount or an integral multiple of $1,000 in excess thereof) for conversion

at any time during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement

Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in

accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported

Sale Price of the Common Stock on each such Trading Day and the Conversion Rate on each such Trading Day. The Trading Prices shall be

determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this

Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three independent

nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate

contact information for each, and the Company shall direct those securities dealers to provide bids to the Bid Solicitation Agent in

accordance with the definition of “Trading Price.” The Bid Solicitation Agent (if other than the Company) shall have no obligation

to solicit the Trading Price per $1,000 principal amount of Notes unless the Company has requested such solicitation in writing, and

the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall

have no obligation to determine the Trading Price per $1,000 principal amount of Notes) unless a Holder of at least $1,000,000 aggregate

principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on

any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the

Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent (if other than the Company)

in writing to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000

principal amount of Notes in accordance with the bids solicited by the Bid Solicitation Agent beginning on the next Trading Day and on

each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product

of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If (x) the Company is not acting as Bid Solicitation

Agent, and the Company does not instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000 principal amount

of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent in writing to obtain

bids and the Bid Solicitation Agent fails to make such determination, or (y) the Company is acting as Bid Solicitation Agent and

the Company fails to make such determination when obligated as provided in the preceding sentence, then, in either case, the Trading

Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the

Common Stock and the Conversion Rate on each Trading Day of such failure. Any such determination shall be conclusive absent manifest

error. If the Trading Price condition set forth above has been met, the Company shall so notify the Holders, the Trustee and the Conversion

Agent (if other than the Trustee) in writing and, for the avoidance of doubt, thereafter, neither the Company nor the Bid Solicitation

Agent (if other than the Company) shall be required to solicit bids again until another request by a Holder in accordance with this subsection

(b)(i) is submitted. If, at any time after the Trading Price condition set forth above has been met, the Trading Price per $1,000

principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the

Conversion Rate for such date, the Company shall so notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than

the Trustee) in writing. Neither the Company nor the Bid Solicitation Agent (if other than the Company) shall have any liability or responsibility

for any Trading Price or related information or the accuracy thereof.

(ii)           If,

prior to the close of business on the Business Day immediately preceding February 15, 2031, the Company elects to:

(A)           issue

to all or substantially all holders of the Common Stock any rights, options or warrants (other than in connection with a stockholder

rights plan prior to separation of such rights from the Common Stock) entitling them, for a period of not more than 45 calendar days

after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less

than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including,

the Trading Day immediately preceding the date of announcement of such issuance; or

(B)           distribute

to all or substantially all holders of the Common Stock the Company’s assets, securities or rights to purchase securities of the

Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported

Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution,

then, in either case, the Company shall notify

in writing the Trustee, the Conversion Agent (if other than the Trustee) and all Holders of the Notes at least 55 Scheduled Trading Days

prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice to a Holder, such Holder may

surrender all or any portion of its Notes (that is at least $1,000 aggregate principal amount or an integral multiple of $1,000 in excess

thereof) for conversion at any time until the earlier of (1) the close of business on the Business Day immediately preceding the

Ex-Dividend Date for such issuance or distribution and (2) the Company’s announcement that such issuance or distribution will

not take place, in each case, even if the Notes are not otherwise convertible at such time. A Holder of the Notes may not exercise its

conversion right under this Section 14.01(b)(ii) if such Holder participates, at the same time and upon the same terms as holders

of the Common Stock and solely as a result of holding the Notes, in any such issuance or distribution without having to convert its Notes

as if such Holder held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed

in thousands) of Notes held by such Holder.

(iii)           If

a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business

on the Business Day immediately preceding February 15, 2031, regardless of whether a Holder has the right to require the Company

to repurchase the Notes pursuant to ‎Section 15.02, or if the Company is a party to a Share Exchange Event that occurs prior

to the close of business on the Business Day immediately preceding February 15, 2031, all or any portion of a Holder’s Notes

may be surrendered for conversion at any time from or after the date that is 55 Scheduled Trading Days prior to the anticipated effective

date of the transaction (or, if later, the earlier of (x) the Business Day after the Company gives notice of such transaction and

(y) the actual effective date of such transaction) until 35 Trading Days after the actual effective date of such transaction or,

if such transaction also constitutes a Fundamental Change (other than an Exempted Fundamental Change), until the related Fundamental

Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than

the earlier of (x) the Business Day following the date the Company publicly announces such transaction and (y) the actual effective

date of such transaction.

(iv)           Prior

to the close of business on the Business Day immediately preceding February 15, 2031, a Holder may surrender all or any portion

of its Notes (that is at least $1,000 aggregate principal amount or an integral multiple of $1,000 in excess thereof) for conversion

at any time during the 30 Trading Day period beginning on, and including, the 21st Trading Day of any fiscal quarter commencing after

the fiscal quarter ending on June 30, 2026, if the Last Reported Sale Price per share of the Common Stock exceeds 130% of the Conversion

Price for each of at least five Trading Days (whether or not consecutive) during the first 20 Trading Days of such fiscal quarter. The

Company shall determine at the beginning of each fiscal quarter commencing after June 30, 2026 whether the Notes may be surrendered

for conversion in accordance with this clause ‎(iv) and shall notify the Holders, the Trustee and the Conversion Agent (if other

than the Trustee) in writing if the Notes become convertible in accordance with this clause (iv).

(v)           If

the Company calls any or all of the Notes for an Optional Redemption or calls all of the Notes for a Cleanup Redemption pursuant to ‎Article 16,

then a Holder may surrender all or any portion of its Notes for conversion at any time prior to the close of business on the Scheduled

Trading Day prior to the applicable Redemption Date, even if the Notes are not otherwise convertible at such time. After that time, the

right to convert such Notes on account of the Company’s delivery of the relevant Redemption Notice shall expire, unless the Company

defaults in the payment of the Redemption Price, in which case a Holder may convert its Notes until the Redemption Price has been paid

or duly provided for.

Section 14.02. Conversion

Procedure; Settlement Upon Conversion.

(a)           Except

as provided in ‎Section 14.03(b) and ‎Section 14.07(a), upon conversion of any Note, on the second Business Day

immediately following the last Trading Day of the relevant Observation Period, the Company shall pay or deliver, as the case may be,

to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a “Settlement Amount”

equal to the sum of the Daily Settlement Amounts for each of the 40 Trading Days during the relevant Observation Period for such Note,

together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection ‎(j) of

this ‎Section 14.02.

(i)            All

conversions of Notes for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect

to the Notes and prior to the related Redemption Date, and all conversions of Notes for which the relevant Conversion Date occurs on

or after February 15, 2031, shall be settled using the same forms and amounts of consideration. Except for any conversions of Notes

for which the relevant Conversion Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes but

prior to the related Redemption Date, and any conversions of Notes for which the relevant Conversion Date occurs on or after February 15,

2031, the Company shall use the same forms and amounts of consideration for all conversions of Notes with the same Conversion Date, but

the Company shall not have any obligation to use the same forms and amounts of consideration with respect to conversions of Notes with

different Conversion Dates. If, in respect of any Conversion Date (or one of the periods described in the third immediately succeeding

set of parentheses, as the case may be), the Company elects to settle all or a portion of its Conversion Obligation in excess of the

principal portion of the Notes being converted in cash in respect of such Conversion Date (or such period, as the case may be), the Company

shall inform converting Holders of such election (the “Settlement Notice”) no later than the close of business on

the Trading Day immediately following the related Conversion Date (or, in the case of any conversions of Notes for which the relevant

Conversion Date occurs (x) after the date of issuance of a Redemption Notice with respect to the Notes and prior to the related

Redemption Date, in such Redemption Notice, or (y) on or after February 15, 2031, no later than February 15, 2031) and

the Company shall indicate in such Settlement Notice the percentage of the consideration due upon conversion in excess of the principal

portion of the Notes being converted that will be paid in cash (the “Cash Percentage”). If the Company does not elect

a Cash Percentage prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to

elect a Cash Percentage and the Company shall be deemed to have elected to settle, and the Company shall settle, its Conversion Obligation

by paying cash in respect of the principal portion of the converted Notes and delivering shares of Common Stock in respect of the remainder

(other than cash in lieu of any fractional share), if any, of its Conversion Obligation in excess of the aggregate principal portion

of the Notes being converted as set forth herein. The Company shall separately provide to the Trustee and the Conversion Agent (if other

than the Trustee) in writing any notice contemplated by this clause (i).

(ii)           The

Daily Settlement Amounts (if applicable), the Daily Net Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable)

shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the

Daily Settlement Amounts, the Daily Net Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash

payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if

other than the Trustee) in writing of the Daily Settlement Amounts, the Daily Net Settlement Amounts or the Daily Conversion Values,

as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion

Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b)           Subject

to ‎Section 14.02(e), before any Holder shall be entitled to convert a Note as set forth above, such Holder shall (i) in

the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to any

Special Interest payable on the next Special Interest Payment

Date to which such Holder is not entitled as set forth in ‎Section 14.02(h) and such conversion shall be irrevocable after

such Holder has complied with the procedures of the Depositary in effect at such time unless the Company, in its sole and absolute discretion,

agrees to permit such Holder to withdraw such conversion and such withdrawal is reasonably feasible pursuant to the procedures of the

Depositary in effect at such time and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable

notice (unless the Company, in its sole and absolute discretion, agrees to permit such Holder to withdraw such notice) to the Conversion

Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) at

the Corporate Trust Office or at the office of the Conversion Agent (if other than the Trustee) and state in writing therein the principal

amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for

any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes,

duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the Corporate Trust

Office or at the office of the Conversion Agent (if other than the Trustee), (3) if required, furnish appropriate endorsements and

transfer documents and (4) if required, pay funds equal to any Special Interest payable

on the next Special Interest Payment Date to which such Holder is not entitled as set forth

in ‎Section 14.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant

to this ‎Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered

by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes

and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with ‎Section 15.03.

more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such

Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted

thereby) so surrendered.

Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”)

that the Holder has complied with the requirements set forth in subsection ‎(b) above. If any shares of Common Stock are due

to a converting Holder, the Company shall issue or cause to be issued, and deliver (if applicable) to the converting Holder, or such

Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format

through the Depositary, in satisfaction of the Company’s Conversion Obligation.

(d)           In

case any Note shall be surrendered for partial conversion in $1,000 aggregate principal amount or an integral multiple of $1,000 in excess

thereof, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note

so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the

surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment

of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or

that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being

different from the name of the Holder of the old Notes surrendered for such conversion.

(e)           If

a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue

of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other

than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates

representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient

to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f)            Except

as provided in ‎Section 14.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion

of any Note as provided in this Article 14.

(g)           Upon

the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation

on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing

of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(h)           Upon

conversion, a Holder shall not receive any separate cash payment for accrued and unpaid Special Interest,

if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full

its obligation to pay the principal amount of the Note and accrued and unpaid Special Interest,

if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid Special Interest, if any, to, but not including,

the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of

Notes, any accrued and unpaid Special Interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding

the foregoing, if Notes are converted after the close of business on a Special Interest Record Date, Holders of such Notes as of the

close of business on such Special Interest Record Date will receive the full amount of any Special Interest payable

on such Notes on the corresponding Special Interest Payment Date notwithstanding the conversion.

Notes surrendered for conversion during the period from the close of business on any Special Interest Record Date to the open of business

on the immediately following Special Interest Payment Date must be accompanied by funds

equal to the amount of any Special Interest payable on the Notes so converted; provided that no such payment shall be required

(1) for conversions of Notes following May 1, 2031, if Special Interest is payable

on the Maturity Date; (2) if the Company has specified a Redemption Date that is after

a Special Interest Record Date and on or prior to the Business Day immediately following the corresponding Special Interest Payment

Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Special Interest Record Date and on

or prior to the Business Day immediately following the corresponding Special Interest Payment Date; or (4) to the extent of any

Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance

of doubt, all Holders of record on May 1, 2031 (if and to the extent Special Interest is payable on the Maturity Date) and the Special

Interest Record Date immediately preceding any Redemption Date or Fundamental Change Repurchase Date described in clause (2) and

(3) of the immediately preceding sentence shall receive the full Special Interest payment

due on the Maturity Date or other applicable Special Interest Payment Date in cash regardless of whether their Notes have been converted

following May 1, 2031 or such Special Interest Record Date.

(i)            The

Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as of the

close of business on the last Trading Day of the related Observation Period. Upon a conversion of Notes, such Person shall no longer

be a Holder of such Notes surrendered for conversion.

(j)            The

Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering

any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the last Trading Day of the relevant Observation

Period. For each Note surrendered for conversion, the full number of shares that shall be issued upon conversion thereof shall be computed

on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after

such computation shall be paid in cash.

Section 14.03. Increased

Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes or Redemption Notice. (a) If

(x) the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date or (y) the Company gives a Redemption

Notice with respect to any or all of the Notes in accordance with ‎Section 16.02 and, in each case, a Holder elects to convert

its Notes in connection with such Make-Whole Fundamental Change or Redemption Notice, as the case may be, the Company shall, under the

circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares

of Common Stock (the “Additional Shares”), as described below. A conversion of Notes shall be deemed for these purposes

to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion

Agent from, and including, the open of business on the Effective Date of the Make-Whole Fundamental Change up to, and including, the

close of business on the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of an Exempted

Fundamental Change or a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause

(b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change)

(such period, the “Make-Whole Fundamental Change Period”). A conversion of Notes shall be deemed for these purposes

to be “in connection with” a Redemption Notice if the relevant Notice of Conversion is received by the Conversion Agent from,

and including, the open of business on the date of the Redemption Notice until the close of business on the Scheduled Trading Day immediately

preceding the related Redemption Date.

(b)           Upon

surrender of Notes for conversion in connection with a Make-Whole Fundamental Change or Redemption Notice, the Company shall satisfy

the related Conversion Obligation in accordance with ‎Section 14.02 based on the Conversion Rate as increased to reflect the

Additional Shares pursuant to the table below; provided, however, that if, at the effective time of a Make-Whole Fundamental

Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental

Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change,

the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount

of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment for Additional Shares),

multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the second Business

Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent (if other than

the Trustee) in writing of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective

Date.

number of Additional Shares, if any, by which the Conversion Rate shall be increased pursuant to this Section 14.03 shall be determined

by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective or the date

of the Redemption Notice, as the case may be, (in each case, the “Effective Date”) and the price (the “Stock

Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change or with respect to an

Optional Redemption or a Cleanup Redemption, as the case may be. If the holders of the Common Stock receive in exchange for their Common

Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price

shall be the cash amount paid per share. In all other cases, the Stock Price shall be the average of the Last Reported Sale Prices of

the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date

of the Make-Whole Fundamental Change or the date of the Redemption Notice, as the case may be. The Board of Directors shall make appropriate

adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective,

or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in ‎Section 14.04)

or expiration date of the event occurs during such five consecutive Trading Day period.

(d)           The

Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the

Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment,

multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the

Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth

in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in ‎Section 14.04.

(e)           The

following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000

principal amount of Notes pursuant to this ‎Section 14.03 for each Stock Price and Effective Date set forth below:

The exact Stock Price and

Effective Date may not be set forth in the table above, in which case:

(i)             if

the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table, the

number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for

the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

(ii)           if

the Stock Price is greater than $3,000.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column

headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii)           if

the Stock Price is less than $339.19 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column

headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall

the Conversion Rate per $1,000 principal amount of Notes exceed 2.9482 shares of Common Stock, subject to adjustment in the same manner

as the Conversion Rate pursuant to ‎Section 14.04.

(f)           Nothing

in this ‎Section 14.03 shall prevent an adjustment to the Conversion Rate pursuant to ‎Section 14.04 in respect of

a Make-Whole Fundamental Change.

Section 14.04. Adjustment

of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs,

except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the

case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms

as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this ‎Section 14.04,

without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied

by the principal amount (expressed in thousands) of Notes held by such Holder.

(a)           If

the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Company

effects a share split or share combination in respect of the Common Stock, the Conversion Rate shall be adjusted based on the following

formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the open of business

on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business

on the Effective Date of such share split or share combination, as applicable;

CR' =

the Conversion Rate in effect immediately after the open

of business on such Ex-Dividend Date or Effective Date, as applicable;

OS0 =

the number of shares of Common Stock outstanding

immediately prior to the open of business on such Ex-Dividend Date or Effective Date, as

applicable (before giving effect to any such dividend, distribution, share split or share

combination, as the case may be); and

OS' =

the number of shares of Common Stock outstanding

immediately after giving effect to such dividend, distribution, share split or share combination,

as the case may be.

Any adjustment made under this ‎Section 14.04(a) shall

become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after

the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution

of the type described in this ‎Section 14.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately

readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate

that would then be in effect if such dividend or distribution had not been declared.

(b)           If

the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a

stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance,

to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale

Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding

the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the open of business

on the Ex-Dividend Date for such issuance;

CR' =

the Conversion Rate in effect immediately after the open

of business on such Ex-Dividend Date;

OS0 =

the number of shares of Common Stock outstanding

immediately prior to the open of business on such Ex-Dividend Date;

X =

the total number of shares of Common Stock issuable pursuant to such rights,

options or warrants; and

Y =

the number of shares of Common Stock equal to the aggregate price payable

to exercise such rights, options or warrants, divided by the average of the Last Reported Sale Prices

of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day

immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this ‎Section 14.04(b) shall

be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of

business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration

of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the

increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares

of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to

the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this ‎Section 14.04(b) and

for the purpose of ‎Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders of the

Common Stock to subscribe for or purchase shares of the Common Stock at a price per share that is less than such average of the Last

Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately

preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock,

there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable

on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights,

options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding

(i) dividends, distributions or issuances (including share splits) as to which an adjustment was effected (or would have been effected

but for the 1% Exception) pursuant to ‎Section 14.04(a) or ‎Section 14.04(b), (ii) dividends or distributions

paid exclusively in cash as to which the provisions set forth in ‎Section 14.04(d) shall apply, (iii) distributions

of Reference Property issued in exchange for, or upon conversion of, the Common Stock as set forth in ‎Section 14.07, and (iv) Spin-Offs

as to which the provisions set forth below in this ‎Section 14.04(c) shall apply (any of such shares of Capital Stock,

evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the

“Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the open of business

on the Ex-Dividend Date for such distribution;

CR' =

the Conversion Rate in effect immediately after the open

of business on such Ex-Dividend Date;

SP0 =

the average of the Last Reported Sale Prices

of the Common Stock over the 10 consecutive Trading Day period ending on, and including,

the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV =

the fair market value (as determined by the Board of Directors) of the

Distributed Property with respect to each outstanding share of the Common Stock on the Ex-Dividend Date

for such distribution.

Any increase made under the

portion of this ‎Section 14.04(c) above shall become effective immediately after the open of business on the Ex-Dividend

Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate

that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined

above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder shall

receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock

receive the Distributed Property, without having to convert its Notes, the amount and kind of Distributed Property such Holder would

have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date

for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes

of this ‎Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing

so consider the prices in such market over the same period used in computing the Last Reported Sale Prices of the Common Stock over the

10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment

pursuant to this ‎Section 14.04(c) where there has been a payment of a dividend or other distribution on the Common Stock

of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit

of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),

the Conversion Rate shall be increased based on the following formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the close of business

on the last Trading Day of the Valuation Period;

CR' =

the Conversion Rate in effect immediately after the close

of business on the last Trading Day of the Valuation Period;

FMV0 =

the average of the Last Reported Sale Prices

of the Capital Stock or similar equity interest distributed to holders of the Common Stock

applicable to one share of the Common Stock (determined by reference to the definition of

Last Reported Sale Price as set forth in ‎Section 1.01 as if references therein

to Common Stock were to such Capital Stock or similar equity interest) over the first 10

consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off

(the “Valuation Period”); and

MP0 =

the average of the Last Reported Sale Prices of the Common Stock over the

Valuation Period.

The increase to the Conversion

Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided

that in respect of any conversion of Notes, for any Trading Day that falls within the relevant Observation Period for such conversion

and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser

number of Trading Days as have elapsed from, and including, the Ex-Dividend Date of such Spin-Off to, and including, such Trading Day

in determining the Conversion Rate as of such Trading Day of such Observation Period.

If such Spin-Off does not

occur, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been

declared, effective as of the date on which the Board of Directors determines not to consummate the Spin-Off.

For purposes of this ‎Section 14.04(c) (and

subject in all respects to ‎Section 14.11), rights, options or warrants distributed by the Company to all holders of the Common

Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially

or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger

Event”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are

also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this ‎Section 14.04(c) (and

no adjustment to the Conversion Rate under this ‎Section 14.04(c) will be required) until the occurrence of the earliest

Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if

any is required) to the Conversion Rate shall be made under this ‎Section 14.04(c). If any such right, option or warrant, including

any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence

of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets,

then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect

to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate

and expire on such date without exercise by any of the holders of the Common Stock thereof). In addition, in the event of any distribution

(or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately

preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to

the Conversion Rate under this ‎Section 14.04(c) was made, (1) in the case of any such rights, options or warrants

that shall all have been redeemed or purchased without exercise by any holders of the Common Stock thereof, upon such final redemption

or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the

Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case

may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of

Common Stock with respect to such rights, options or warrants (assuming such holder of the Common Stock had retained such rights, options

or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights,

options or warrants that shall have expired or been terminated without exercise by any holders of the Common Stock thereof, the Conversion

Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of ‎Section 14.04(a),

‎Section 14.04(b) and this ‎Section 14.04(c), if any dividend or distribution to which this ‎Section 14.04(c) is

applicable also includes one or both of:

(A)          a

dividend or distribution of shares of Common Stock to which ‎Section 14.04(a) is applicable (the “Clause A Distribution”);

(B)           a

dividend or distribution of rights, options or warrants to which ‎Section 14.04(b) is applicable (the “Clause

B Distribution”),

then, in either case, (1) such dividend

or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution

to which this ‎Section 14.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate

adjustment required by this ‎Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the

Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate

adjustment required by ‎Section 14.04(a) and ‎Section 14.04(b) with respect thereto shall then be made, except

that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution

shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause

A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such

Ex-Dividend Date or Effective Date” within the meaning of ‎Section 14.04(a) or “outstanding immediately prior

to the open of business on such Ex-Dividend Date” within the meaning of ‎Section 14.04(b).

(d)           If

any cash dividend or distribution is made to all or substantially all holders of the Common Stock, other than a regular, quarterly cash

dividend that does not exceed $0.10 per share (the “Initial Dividend Threshold”), the Conversion Rate shall be adjusted

based on the following formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the open of business

on the Ex-Dividend Date for such dividend or distribution;

CR' =

the Conversion Rate in effect immediately after the open

of business on the Ex-Dividend Date for such dividend or distribution;

SP0 =

the Last Reported Sale Price of the Common

Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or

distribution;

T =

the Initial Dividend Threshold; provided

that if the dividend or distribution is not a regular, quarterly cash dividend, the Initial

Dividend Threshold shall be deemed to be zero; and

C =

the aggregate amount in cash per share the

Company distributes to all or substantially all holders of the Common Stock.

The Initial Dividend Threshold shall be subject

to adjustment in a manner inversely proportional to adjustments to the Conversion Rate; provided that no adjustment shall be made

to the Initial Dividend Threshold for any adjustment to the Conversion Rate pursuant to this ‎Section 14.04(d).

Any increase pursuant to this ‎Section 14.04(d) shall

become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or

distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to

make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had

not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0”

(as defined above), in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes it holds,

at the same time and upon the same terms as holders of the Common Stock, without having to convert its Notes, the amount of cash that

such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the

Ex-Dividend Date for such cash dividend or distribution.

(e)           If

the Company or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Common Stock that is subject to

the then applicable tender offer rules under the Exchange Act (other than an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under

the Exchange Act or any successor rule), to the extent that the cash and value of any other consideration included in the payment per

share of the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day

period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant

to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

where,

CR0 =

the Conversion Rate in effect immediately prior to the close of business

on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date

such tender or exchange offer expires (the date such tender or exchange offer expires, the “Expiration

Date”);

CR' =

the Conversion Rate in effect immediately after the close

of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding

Expiration Date;

AC =

the aggregate value of all cash and any other

consideration (as determined by the Board of Directors) paid or payable for the shares of

Common Stock purchased in such tender or exchange offer;

OS0 =

the number of shares of Common Stock outstanding immediately prior to the

Expiration Date (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase

or exchange in such tender or exchange offer);

OS' =

the number of shares of Common Stock outstanding

immediately after the Expiration Date (after giving effect to the purchase of all shares

of Common Stock accepted for purchase or exchange in such tender or exchange offer); and

SP' =

the average of the Last Reported Sale Prices

of the Common Stock over the 10 consecutive Trading Day period commencing on, and including,

the Trading Day next succeeding Expiration Date.

The increase to the Conversion

Rate under this ‎Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and

including, the Trading Day next succeeding the relevant Expiration Date; provided that in respect of any conversion of Notes,

for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately

following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10”

or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed from,

and including, the Trading Day next succeeding the relevant Expiration Date to, and including, such Trading Day in determining the Conversion

Rate as of such Trading Day of such Observation Period.

In the event that the Company

or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the

Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded,

then the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange

offer had not been made or had been made only in respect of the purchases that have been effected.

(f)            [Reserved].

(g)            Except

as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of the Common Stock or any securities convertible

into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable

securities.

(h)            In

addition to those adjustments required by clauses ‎(a), ‎(b), ‎(c), ‎(d) and ‎(e) of this ‎Section 14.04,

and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s

securities are then listed, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business

Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent

permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are

then listed, the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common

Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire

shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences,

the Company shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the increased Conversion

Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i)            Notwithstanding

anything to the contrary in this ‎Article 14, the Conversion Rate shall not be adjusted:

(i)            upon

the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest

payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii)           upon

the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director

or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

(iii)          upon

the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security

not described in clause ‎(ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv)          upon

the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is

not a tender offer or exchange offer of the nature described in Section 14.04(e) above;

(v)           for

a tender offer by any party other than a tender offer by the Company or one or more of its Subsidiaries as described in Section 14.04(e);

(vi)          solely

for a change in the par value of the Common Stock; or

(vii)         for

accrued and unpaid Special Interest, if any.

(j)            All

calculations and other determinations under this ‎Article 14 shall be made by the Company and shall be made to the nearest one-ten

thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment to the Conversion Rate pursuant to this ‎Section 14.04

unless the adjustment would require a change of at least 1% in the Conversion Rate; provided that the Company shall carry forward

any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments, regardless of whether the aggregate

adjustment is at least 1%, (1) on the Effective Date for any Make-Whole Fundamental Change and/or the effective date of any Fundamental

Change, (2) on any date the Company delivers a Redemption Notice, (3) prior to the close of business on the Conversion Date

in respect of any conversion following a replacement of the Common Stock by Reference Property consisting solely of cash, (4) prior

to the open of business on each Trading Day of any Observation Period in respect of the conversion of any Note (other than as described

in clause (3)), (5) on the date on which all such deferred adjustments would result in an aggregate change to the Conversion Rate

of at least 1% and (6) on February 15, 2031.

(k)            Whenever

the Conversion Rate is adjusted as herein provided, the Company shall promptly furnish to the Trustee (and the Conversion Agent if not

the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement

of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s

Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry

that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall

prepare a written notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each

adjustment becomes effective and shall deliver such notice of such adjustment of the Conversion Rate to each Holder (with a copy to the

Trustee). Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l)            For

purposes of this ‎Section 14.04, the number of shares of Common Stock at any time outstanding shall not include shares of Common

Stock held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common

Stock held in the treasury of the Company, but shall include shares of Common Stock issuable in respect of scrip certificates issued in

lieu of fractions of shares of Common Stock.

Section 14.05. Adjustments

of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs,

the Daily Conversion Values, the Daily Net Settlement Amounts or the Daily Settlement Amounts over a span of multiple days (including,

without limitation, an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change,

Optional Redemption or Cleanup Redemption), the Company shall, in good faith, make appropriate adjustments to each to account for any

adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend

Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported

Sale Prices, the Daily VWAPs, the Daily Conversion Values, the Daily Net Settlement Amounts or the Daily Settlement Amounts are to be

calculated.

Section 14.06.

Shares to Be Fully Paid. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares

held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented

for conversion (assuming delivery of the maximum number of shares of Common Stock that may be due upon conversion, the addition of the

maximum number of Additional Shares to the Conversion Rate pursuant to Section 14.03 and that at the time of computation of such

number of shares, all such Notes would be converted by a single Holder).

Section 14.07. Effect

of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a)            In

the case of:

(i)            any

recapitalization, reclassification or change of the Common Stock (other than changes in par value or changes resulting from a subdivision

or combination),

(ii)           any

consolidation, merger, combination or similar transaction involving the Company,

(iii)          any

sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially

as an entirety, or

(iv)          any

statutory share exchange,

in each case, as a result of which the Common

Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination

thereof) (any such event, a “Share Exchange Event”), then, at and after the effective time of such Share Exchange Event,

the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into

the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that

a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Share Exchange Event would have

owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property”

meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange

Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or purchasing Person, as the case

may be, shall execute with the Trustee a supplemental indenture permitted under ‎Section 10.01(g) providing for such change

in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after the effective time of

the Share Exchange Event, the Conversion Obligation shall be calculated and settlement in accordance with ‎Section 14.02 such

that (A) the amount otherwise payable in cash upon conversion of the Notes as set forth under ‎Section 14.02 shall continue

to be payable in cash, (B) the Company shall continue to have the right to elect to determine the form of consideration to be paid

or delivered, as the case may be, in respect of the remainder, if any, of the Conversion Obligation in excess of the principal amount

of the Notes being converted as set forth under ‎Section 14.02, (C) the number of shares of Common Stock, if any, otherwise

deliverable upon conversion of the Notes in accordance with ‎Section 14.02 shall instead be deliverable in the amount and type

of Reference Property that a holder of that number of shares of Common Stock would have received in such Share Exchange Event and (D) the

Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Share Exchange Event

causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined

based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall

be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the

unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause

(i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than

the Trustee) in writing of such weighted average as soon as practicable after such determination is made. If the holders of the Common

Stock receive only cash in such Share Exchange Event, then for all conversions of Notes for which the relevant Conversion Date occurs

after the effective date of such Share Exchange Event (A) the consideration due upon conversion of each $1,000 principal amount of

Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional

Shares pursuant to ‎Section 14.03), multiplied by the price paid per share of Common Stock in such Share Exchange Event

and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately

following the relevant Conversion Date.

Such supplemental indenture

described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly

equivalent as is possible to the adjustments provided for in this ‎Article 14. If, in the case of any Share Exchange Event, the

Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person

other than the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such supplemental indenture

shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the

Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for

the purchase rights set forth in ‎Article 15.

(b)            When

the Company executes a supplemental indenture pursuant to subsection ‎(a) of this ‎Section 14.07, the Company shall

promptly furnish to the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities

or property or asset that will comprise a unit of Reference Property after any such Share Exchange Event, any adjustment to be made with

respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The

Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 days after execution

thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

Company shall not become a party to any Share Exchange Event unless its terms are consistent with this ‎Section 14.07. None of

the foregoing provisions shall affect the right of a Holder to convert its Notes into cash and shares of Common Stock, if any, as set

forth in ‎Section 14.01 and ‎Section 14.02 prior to the effective date of such Share Exchange Event.

(d)            The

above provisions of this Section shall similarly apply to successive Share Exchange Events.

(e)            In

connection with any Share Exchange Event, the Initial Dividend Threshold shall be subject to adjustment as described in clause (i), clause

(ii) or clause (iii) below, as the case may be.

(i)            In

the case of a Share Exchange Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above

and excluding any dissenters’ appraisal rights) is composed entirely of shares of common stock or American depositary receipts (or

other interests) in respect thereof (the “Share Exchange Common Stock”), the Initial Dividend Threshold at and after

the effective time of such Share Exchange Event will be equal to (x) the Initial Dividend Threshold immediately prior to the effective

time of such Share Exchange Event, divided by (y) the number of shares of Share Exchange Common Stock that a holder of one

share of Common Stock would receive in such Share Exchange Event (such quotient rounded down to the nearest cent).

(ii)           In

the case of a Share Exchange Event in which the Reference Property (determined, as appropriate, pursuant to subsection (a) above

and excluding any dissenters’ appraisal rights) is composed in part of shares of Share Exchange Common Stock, the Initial Dividend

Threshold at and after the effective time of such Share Exchange Event will be equal to (x) the Initial Dividend Threshold immediately

prior to the effective time of such Share Exchange Event, multiplied by (y) the Share Exchange Valuation Percentage for such

Share Exchange Event (such product rounded down to the nearest cent).

(iii)          For

the avoidance of doubt, in the case of a Share Exchange Event in which the Reference Property (determined, as appropriate, pursuant to

subsection (a) above and excluding any dissenters’ appraisal rights) is composed entirely of consideration other than shares

of common stock or American depositary receipts (or other interests) in respect thereof, the Initial Dividend Threshold at and after the

effective time of such Share Exchange will be equal to zero.

Section 14.08. Certain

Covenants. (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable

by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(b)            The

Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration

with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued

upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration

or approval, as the case may be.

Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation

system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system,

any Common Stock issuable upon conversion of the Notes.

Section 14.09.

Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to

any Holder to determine, or verify the Company’s determination of, the Conversion Rate (or any adjustment thereto) or whether

any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent

or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided

to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or

value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or

delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto.

Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares

of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion

or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality

of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions

contained in any supplemental indenture entered into pursuant to ‎Section 14.07 relating either to the kind or amount of shares

of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred

to in such ‎Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of ‎Section 7.01,

may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected

in conclusively relying upon, the Officer’s Certificate (which the Company shall be obligated to furnish to the Trustee prior to

the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible

for determining whether any event contemplated by ‎Section 14.01(b) has occurred that makes the Notes eligible for conversion

or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in ‎Section 14.01(b) with

respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively

rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such

event or at such other times as shall be provided for in ‎Section 14.01(b). The parties hereto agree that all notices to the

Trustee or the Conversion Agent under this ‎Article 14 shall be in writing or as otherwise provided herein. Neither the Trustee

nor any agent acting under this Indenture (other than the Company, if acting in such capacity) shall have any obligation to make any calculation

or determine whether Notes may be surrendered for conversion pursuant to this Indenture, or to notify the Company or the Depositary or

any Holders of the Notes that the Notes have become convertible pursuant to the terms of this Indenture.

Section 14.10. [Reserved].

Section 14.11. Stockholder

Rights Plans. If the Company has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if

any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing

the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such

stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have

separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Conversion

Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock

Distributed Property as provided in ‎Section 14.04(c), subject to readjustment in the event of the expiration, termination or

redemption of such rights.

Section 14.12. Exchange

in lieu of conversion. (a) When a Holder surrenders its Notes for conversion, the Company may, at its election (an “Exchange

Election”), direct the surrender, on or prior to the Trading Day immediately following the Conversion Date, of such Notes to

one or more financial institutions designated by the Company (each, a “Designated Financial Institution”) for exchange

in lieu of conversion. In order to accept any Notes surrendered for conversion, the Designated Financial Institution(s) must agree

to timely pay and deliver, as the case may be, in exchange for such Notes, cash up to the aggregate principal amount of such Notes, and

cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, in respect of the remainder

if any, of the Company’s Conversion Obligation in excess of the aggregate principal amount of such Notes that would otherwise be

due upon conversion pursuant to ‎Section 14.02 (the “Conversion Consideration”). If the Company makes an Exchange

Election, the Company shall, before the close of business on the Trading Day immediately following the relevant Conversion Date, notify

in writing the Trustee, the Conversion Agent (if other than the Trustee) and the Holder surrendering its Notes for conversion that the

Company has made the Exchange Election, and the Company shall notify the Designated Financial Institution(s) of the relevant deadline

for delivery of the Conversion Consideration and the type of Conversion Consideration to be paid and delivered, as the case may be.

(b)            Notwithstanding

the surrender, any Notes delivered to the Designated Financial Institution(s) shall remain outstanding, subject to applicable procedures

of the Depositary. If the Designated Financial Institution(s) agree(s) to accept any Notes for exchange but does not timely

pay and deliver, as the case may be, the related Conversion Consideration, or if such Designated Financial Institution does not accept

the Notes for exchange, the Company shall pay and deliver, as the case may be, the relevant Conversion Consideration as, and at the time,

required pursuant to this Indenture as if the Company had not made the Exchange Election.

Company’s designation of any Designated Financial Institution(s) to which the Notes may be submitted for exchange does not

require such Designated Financial Institution(s) to accept any Notes. The Company, the Conversion Agent and the Holders surrendering

their Notes for conversion will cooperate to cause such Notes to be delivered to the Designated Financial Institution and the Conversion

Agent shall be entitled to conclusively rely on the Company’s instructions in connection with effecting any Exchange Election and

shall have no liability for any such Exchange Election made outside of its control.

Article 15

Repurchase of Notes at Option of Holders

Section 15.01. [Intentionally Omitted]

Section 15.02. Repurchase

at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change (other than an Exempted Fundamental Change) occurs

at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such

Holder’s Notes, or any portion thereof that is equal to $1,000 or an integral multiple of $1,000, on the date (the “Fundamental

Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following

the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus any

accrued and unpaid Special Interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change

Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Special Interest Record Date but on or prior

to the Special Interest Payment Date to which such Special Interest Record Date relates, in which case the Company shall instead pay the

full amount of accrued and unpaid Special Interest to Holders of record as of such Special Interest Record Date, and the Fundamental Change

Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this ‎Article 15.

(b)            Repurchases

of Notes under this ‎Section 15.02 shall be made, at the option of the Holder thereof, upon:

(i)            delivery

to the applicable Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”)

in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or

in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each

case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii)           delivery

of the Notes, if the Notes are Physical Notes, to the applicable Paying Agent at any time after delivery of the Fundamental Change Repurchase

Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry transfer

of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition

to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

The Fundamental Change Repurchase

Notice in respect of any Notes to be repurchased shall state:

(iii)          in

the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(iv)          the

portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

(v)           that

the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided,

however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein

to the contrary, any Holder delivering to the applicable Paying Agent the Fundamental Change Repurchase Notice contemplated by this ‎Section 15.02

shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business

on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the

applicable Paying Agent in accordance with ‎Section 15.03.

The applicable Paying Agent

shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

The Company may appoint a

tender agent in connection with any such repurchase, in which case such tender agent shall be the Paying Agent in connection with such

repurchase.

or before the twentieth calendar day after the occurrence of the effective date of a Fundamental Change (other than an Exempted Fundamental

Change), the Company shall provide to all Holders of Notes, the Trustee, the Conversion Agent (if other than the Trustee) and the applicable

Paying Agent (in the case of any applicable Paying Agent other than the Trustee) a written notice (the “Fundamental Change Company

Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the

Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global

Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with the Company’s

providing such notice, the Company shall publish the information on the Company’s website or through such other public medium as

the Company may use at that time. Each Fundamental Change Company Notice shall specify:

(i)            the

events causing the Fundamental Change;

(ii)           the

effective date of the Fundamental Change;

(iii)          the

last date on which a Holder may exercise the repurchase right pursuant to this ‎Article 15;

(iv)          the

Fundamental Change Repurchase Price;

(v)           the

Fundamental Change Repurchase Date;

(vi)          the

name and address of the applicable Paying Agent and the Conversion Agent, if applicable;

(vii)         if

applicable, the Conversion Rate and any adjustments to the Conversion Rate;

(viii)         that

the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder

withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

(ix)          the

procedures that Holders must follow to require the Company to repurchase their Notes.

No failure of the Company

to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings

for the repurchase of the Notes pursuant to this ‎Section 15.02.

At the Company’s written

request, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided, however,

that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. In such a case, the Company shall

deliver such notice to the Trustee at least three Business Days prior to the date that the notice is required to be given to the Holders

(unless a shorter period is agreed to by the Trustee), together with an Officer’s Certificate requesting that the Trustee give such

notice.

(d)            Notwithstanding

the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal

amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of

an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such

Notes). The applicable Paying Agent will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration

of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase

Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary

shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice

with respect thereto shall be deemed to have been withdrawn.

(e)            Notwithstanding

anything to the contrary in this Article 15, the Company shall not be required to send a Fundamental Change Company Notice, nor offer

to repurchase or repurchase any Notes, in each case, as described in this Section 15.02, in connection with any Exempted Fundamental

Change.

Section 15.03. Withdrawal

of Fundamental Change Repurchase Notice. (a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by

means of a written notice of withdrawal delivered to the office of the applicable Paying Agent in accordance with this ‎Section 15.03

at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

(i)            the

principal amount of the Notes with respect to which such notice of withdrawal is being submitted, which portion must be in principal amounts

of $1,000 or an integral multiple of $1,000 in excess thereof,

(ii)           if

Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted,

Date”) and it or, at its written request in an Officer’s Certificate received by the Trustee not less than five Business

Days prior to the date such Optional Redemption Notice or Cleanup Redemption Notice is to be sent (or such shorter period of time as may

be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be delivered a

(b)            The

Redemption Notice, if delivered in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not

the Holder receives such notice. In any case, failure to give such Redemption Notice by mail or any defect in the Redemption Notice to

the Holder of any Note designated for Optional Redemption (as a whole or in part) or for Cleanup Redemption, as the case may be, shall

not affect the validity of the proceedings for the redemption of any other Note.

shall be issued.

A Redemption Notice shall be irrevocable.

(d)            In

connection with an Optional Redemption, if fewer than all of the outstanding Notes are to be redeemed, in the case of a Global Note, the

Notes or portions thereof to be redeemed (in principal amounts of $1,000 or multiples thereof) shall be selected according to the applicable

procedures of the Depositary, or, in the case of Physical Notes, the Notes to be redeemed (in principal amounts of at least $1,000 or

$1,000 multiples in excess thereof) shall be selected by the Trustee on a pro rata basis or by another method the Trustee considers

to be fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the

portion of the Note submitted for conversion shall be deemed (so far as may be possible) to be the portion selected for Optional Redemption.

Section 16.03.

Payment of Notes Called for Redemption. (a) If any Redemption Notice has been given in respect of the Notes in accordance

with ‎Section 16.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption

Price of all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes

[FORM OF REVERSE OF NOTE]

ADVANCED ENERGY INDUSTRIES, INC.

0% Convertible Senior Note due 2031

This Note is one of a duly

authorized issue of Notes of the Company, designated as its 0% Convertible Senior Notes due 2031 (the “Notes”), limited

to the aggregate principal amount of $1,150,000,000 all issued or to be issued under and pursuant to an Indenture dated as of May 18,

2026 (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”),

to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights,

obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued

in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used in this Note

and not defined in this Note shall have the respective meanings set forth in the Indenture.

In case certain Events of

Default shall have occurred and be continuing, the principal of, and Special Interest, if any, on, all Notes may be declared, by either

the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become,

due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions

of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental

Change Repurchase Date, the Redemption Price on any Redemption Date and the principal amount on the Maturity Date, as the case may be,

to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts

in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions

permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other

circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding,

evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described

therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount

of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under

the Indenture and its consequences.

Each Holder shall have the

right to receive payment or delivery, as the case may be, of (x) the principal (including the Redemption Price and the Fundamental

Change Repurchase Price, if applicable) of, (y) accrued and unpaid Special Interest, if any, on, and (z) the consideration due

upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money or shares of Common Stock, as

the case may be, herein prescribed.

The Notes are issuable in

registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of

the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged

for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required

by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith

as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder

of the old Notes surrendered for such exchange.

Except in the case of a Cleanup

Redemption, the Notes shall not be redeemable by the Company prior to May 21, 2029. The Notes shall be redeemable at the Company’s

option on or after May 21, 2029 in accordance with the terms and subject to the conditions specified in the Indenture. No sinking

fund is provided for the Notes.

Upon the occurrence of a Fundamental

Change (other than an Exempted Fundamental Change), the Holder has the right, at such Holder’s option, to require the Company to

repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof)

on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

Subject to the provisions

of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions

specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date,

to convert this Notes or a portion hereof that is $1,000 or an integral multiple thereof, into cash and shares of Common Stock, if any,

at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

1. This

Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this

Confirmation relates. This Confirmation shall supplement, form a part of, and be subject to an agreement in the form of the ISDA 2002

Master Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form on the Trade

Date (but without any Schedule except for (i) the election of the laws of the State of New York as the governing law (without reference

to choice of law doctrine other than Sections 5-1401 and 5-1402 of the General Obligations Law); [(ii) the election of an executed

Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of

the Exchange Act (as defined below) and the rules and regulations thereunder, in respect of any election (or any deemed election)

of a settlement method with respect to the Convertible Notes.

Valuation

Time:

At the close of trading of the regular

trading session on the Exchange; provided that if the principal trading session is extended, the Calculation Agent shall determine

the Valuation Time in good faith and in its commercially reasonable discretion.

Market

Disruption Event:

A “Market Disruption Event” as defined

in the Indenture.

Settlement Terms.

Settlement Method:

For any Option, Net Share Settlement;

provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement

Method for such Option shall be such Relevant Settlement Method, but only if Counterparty (or any agent authorized by Counterparty

and previously identified to Dealer by Counterparty in writing) shall have notified Dealer of the Relevant Settlement Method in the

Notice of Final Settlement Method for such Option. If any such agent on behalf of Counterparty provides any such notice, Dealer shall

be entitled to rely on the accuracy of such notice without any independent investigation, and the contents of such notice shall be

binding on Counterparty.

Relevant Settlement Method:

In respect of any Option:

(i) if Counterparty has not elected to settle

all or any portion of its conversion obligations in respect of the related Convertible Note in excess of the principal amount thereof

in cash either by specifying a Cash Percentage of 0% or not timely specifying a Cash Percentage, in each case, pursuant to Section

14.02(a)(i) of the Indenture, then the Relevant Settlement Method for such Option shall be Net Share Settlement;

(ii) if Counterparty has elected to settle its conversion obligations in

respect of the related Convertible Note in excess of the principal amount thereof in a combination of cash and Shares by specifying

a Cash Percentage less than 100% but greater than 0% pursuant to Section 14.02(a)(i) of the Indenture, then the Relevant

Settlement Method for such Option shall be Combination Settlement; and

(iii) if Counterparty has elected to settle its conversion obligations in

respect of the related Convertible Note in excess of the principal amount thereof entirely in cash by specifying a Cash Percentage

of 100% pursuant to Section 14.02(a)(i) of the Indenture, then the Relevant Settlement Method for such Option shall be

Cash Settlement.

Net Share Settlement:

If Net Share Settlement is applicable

to any Option exercised or deemed exercised hereunder, Dealer will deliver to Counterparty, on the relevant Settlement Date for each

such Option, a number of Shares (the “Net Share Settlement Amount”) equal to the sum, for each Valid Day during

the Settlement Averaging Period for each such Option, of (i) (a) the Daily Option Value for such Valid Day, divided by (b)

the Relevant Price on such Valid Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided

that in no event shall the Net Share Settlement Amount for any Option exceed a number of Shares equal to the Applicable Limit for

such Option divided by the Applicable Limit Price on the settlement date for the conversion of the relevant Convertible Note(s).

Dealer will pay cash in lieu of delivering any

fractional Shares to be delivered with respect to any Net Share Settlement Amount valued at the Relevant Price for the last Valid

Day of the Settlement Averaging Period.

Combination Settlement:

If Combination Settlement is applicable to any

Option exercised or deemed exercised hereunder, Dealer will pay or deliver, as the case may be, to Counterparty, on the relevant

Settlement Date for each such Option:

(i) cash (the “Combination

Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement

Averaging Period for such Option, of (A) an amount (the “Daily Combination

Settlement Cash Amount”) equal to the product of (1) the Cash Percentage and

(2) the Daily Option Value, divided by (B) the number of Valid Days in the

Settlement Averaging Period; provided that if the calculation in clause (A) above

results in zero or a negative number for any Valid Day, the Daily Combination Settlement

Cash Amount for such Valid Day shall be deemed to be zero; and

(ii) Shares (the “Combination

Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement

Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily

Combination Settlement Share Amount”) equal to (A) (1) the Daily Option

Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such

Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by

(B) the number of Valid Days in the Settlement Averaging Period; provided that

if the calculation in sub-clause (A)(1) above results in zero or a negative number for

any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be

deemed to be zero;

provided that in

no event shall the sum of (x) the Combination Settlement Cash Amount for any Option

and (y) the Combination Settlement Share Amount for such Option multiplied by

the Applicable Limit Price on the settlement date for the conversion of the relevant Convertible

Note(s), exceed the Applicable Limit for such Option.

Dealer will pay cash in lieu of delivering any fractional Shares to be

delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the

last Valid Day of the Settlement Averaging Period.

Cash Settlement:

If Cash Settlement is applicable to

any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty,

on the relevant Settlement Date for each such Option, an amount of cash (the “Cash Settlement Amount”) equal to

the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (i) the Daily Option Value for such Valid

Day, divided by (ii) the number of Valid Days in the Settlement Averaging Period; provided that in no event shall the

Cash Settlement Amount for any Option exceed the Applicable Limit for such Option.

Daily Option Value:

For any Valid Day, an amount equal to (i) the

Option Entitlement on such Valid Day, multiplied by (ii) (A) the lesser of the Relevant Price on such Valid Day and the Cap

Price, less (B) the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above

results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero. In no event will the Daily Option

Value be less than zero.

Applicable Limit:

For any Option, an amount of cash equal to the

Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash paid to the “Holder”

(as such term is defined in the Indenture) of the related Convertible Note upon conversion of such Convertible Note and (B) the number

of Shares, if any, delivered to the “Holder” (as such term is defined in the Indenture) of the related Convertible Note

upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the settlement date for the conversion

of the relevant Convertible Note(s), over (ii) USD 1,000.

Applicable Limit Price:

On any day, the opening price as displayed under

the heading “Op” on Bloomberg page AEIS <equity> (or any successor thereto).

Valid Day:

A “Trading Day” for purposes of determining

the amounts due upon conversion of the Convertible Notes as defined in the Indenture.

Scheduled Valid Day:

A “Scheduled Trading Day” as defined

in the Indenture.

Business Day:

Indenture.

Relevant Price:

On any Valid Day, the per Share volume-weighted

average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page AEIS <equity> AQR (or its equivalent

successor if such page is not available) in respect of the period from the scheduled open of trading on the Exchange to the Scheduled

Closing Time of the Exchange on such Valid Day (or if such volume-weighted average price is unavailable at such time, the market

value of one Share on such Valid Day, as determined by the Calculation Agent in good faith and in a commercially reasonable manner

using, if practicable, a volume-weighted average method). The Relevant Price will be determined without regard to after-hours trading

or any other trading outside of the regular trading session trading hours.

Settlement

Averaging Period:

For any Option, the 40 consecutive

Valid Days commencing on, and including, the 41st Scheduled Valid Day immediately prior to the Expiration Date.

Settlement

Date:

For any Option, the second Business Day immediately

following the final Valid Day of the Settlement Averaging Period for such Option.

Other

Applicable Provisions:

The provisions of Sections 9.1(c), 9.8, 9.9 and

9.11 of the Equity Definitions will be applicable, except that all references in such provisions to “Physically-settled”

shall be read as references to “Share Settled”. “Share Settled” in relation to any Option means that Net

Share Settlement or Combination Settlement is applicable to that Option.

Representation

and Agreement:

Notwithstanding anything to the contrary in the

Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to

Counterparty shall be, upon delivery, subject to restrictions and limitations arising from Counterparty’s status as issuer

of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated

form in lieu of delivery through the Clearance System, (iii) any Shares delivered to Counterparty may be “restricted securities”

(as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)) and (iv) the Representation

and Agreement contained in Section 9.11 of the Equity Definitions shall be deemed modified accordingly.

3. Additional

Terms applicable to the Transaction.

Adjustments applicable to the Transaction:

Potential Adjustment

Events:

Notwithstanding Section 11.2(e) of the Equity Definitions,

a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in any Dilution Adjustment

Provision, that requires an adjustment under the Indenture to the “Conversion Rate” or the composition of a “unit

of Reference Property” or to any “Last Reported Sale Price,” “Daily VWAP,” “Daily Conversion

Value,” “Daily Net Settlement Amount” or “Daily Settlement Amount” (each as defined in the Indenture).

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to

the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders

of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes

are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately

preceding sentence (including, without limitation, pursuant to the fourth sentence of Section 14.04(c) of the Indenture

or the fifth sentence of Section 14.04(d) of the Indenture).

Method of Adjustment:

Calculation Agent Adjustment, which shall not have the meaning set

forth in Section 11.2(c) of the Equity Definitions and instead shall mean that, upon any Potential Adjustment Event, the

Calculation Agent shall (A) make adjustments in good faith and in a commercially reasonable manner to any one or more of the

Strike Price, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction (other

than the Cap Price and Number of Options) that correspond to the adjustments to the Convertible Notes under the Indenture, and (B) make

a proportionate adjustment to the Cap Price to the extent any adjustment is made to the Strike Price pursuant to clause (A) above

(which adjustment, for the avoidance of doubt, shall not prohibit the Calculation Agent from making any further adjustment to the

Cap Price in accordance with, and subject in all respects to, the provisions of “Consequences of Announcement Events”

below and Section 9(y) hereof) (provided that in no event shall the Strike Price be greater than the Cap Price).

Notwithstanding the foregoing and “Consequences of Merger Events / Tender

Offers” below, if the Calculation Agent in good faith disagrees with any adjustment to the Convertible Notes determined pursuant

to the Indenture that is the basis of any adjustment hereunder and that involves an exercise of discretion by Counterparty or its

board of directors (including, without limitation, pursuant to Section 14.05 of the Indenture, Section 14.07 of the Indenture

or any supplemental indenture entered into thereunder or in connection with any proportional adjustment or the determination of the

fair value of any securities, property, rights or other assets), then in each such case, the Calculation Agent will (A) determine

the adjustment to be made to any one or more of the Strike Price, Option Entitlement and any other variable relevant to the exercise,

settlement or payment for the Transaction (other than the Cap Price and Number of Options), using, if applicable, the methodology

set forth in the Indenture for any such adjustment, in good faith and in a commercially reasonable manner, taking into account the

relevant provisions of the Indenture, and (B) make a proportionate adjustment to the Cap Price to the extent any adjustment

is made to the Strike Price pursuant to clause (A) above (which adjustment, for the avoidance of doubt, shall not prohibit the

Calculation Agent from making any further adjustments to the Cap Price in accordance with, and subject in all respects to, the provisions

of “Consequences of Announcement Events” below and Section 9(y) hereof) (provided that in no event shall

the Strike Price be greater than the Cap Price).

Notwithstanding anything contained herein to the contrary, (i) in

connection with any Potential Adjustment Event as a result of an event or condition set forth in Section 14.04(b) of the

Indenture or Section 14.04(c) of the Indenture where, in either case, the period for determining “Y” (as such

term is used in Section 14.04(b) of the Indenture) or “SP0” (as such term is used in Section 14.04(c) of

the Indenture), as the case may be, begins before Counterparty has publicly announced the event or condition giving rise to such

Potential Adjustment Event, then the Calculation Agent shall, acting in good faith and in a commercially reasonable manner, have

the right to adjust the Cap Price as appropriate (but in no case to a number lower than the Strike Price) to reflect the commercially

reasonable costs (including, but not limited to, hedging mismatches and market losses) and commercially reasonable and documented

out-of-pocket expenses incurred by Dealer in connection with its hedging activities, with such adjustments made assuming that Dealer

maintains commercially reasonable hedge positions, as a result of such event or condition not having been publicly announced prior

to the beginning of such period and (ii) if any Potential Adjustment Event is declared and (a) the event or condition giving

rise to such Potential Adjustment Event is subsequently amended, modified, cancelled or abandoned, (b) the “Conversion

Rate” (as defined in the Indenture) is otherwise not adjusted at the time or in the manner contemplated by the relevant Dilution

Adjustment Provision based on such declaration or (c) the “Conversion Rate” (as defined in the Indenture) is adjusted

as a result of such Potential Adjustment Event and subsequently re-adjusted (each of clauses (a), (b) and (c), a “Potential

Adjustment Event Change”) then, in each case, the Calculation Agent shall have the right to adjust the Cap Price (but in

no case to a number lower than the Strike Price) as appropriate to reflect the commercially reasonable costs (including, but not

limited to, hedging mismatches and market losses) and commercially reasonable and documented out-of-pocket expenses incurred by Dealer

in connection with its commercially reasonable hedging activities as a result of such Potential Adjustment Event Change, with such

adjustments made assuming that Dealer maintains commercially reasonable hedge positions.

Dilution Adjustment Provisions:

Sections 14.04(a), (b), (c), (d) and (e) and Section 14.05 of

the Indenture.

Extraordinary Events applicable to

the Transaction:

Merger Events:

Applicable; provided that notwithstanding Section 12.1(b) of

the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in the definition of

“Share Exchange Event” in Section 14.07(a) of the Indenture.

Tender Offers:

Applicable; provided that “Tender Offer” shall not have the

meaning set forth in Section 12.1(d) of the Equity Definitions and instead shall mean the occurrence of any event or condition

set forth in Section 14.04(e) of the Indenture.

Consequences of Merger Events/ Tender

Offers:

Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions,

upon the occurrence of a Merger Event or a Tender Offer, the Calculation Agent shall (A) make a corresponding adjustment in

respect of any adjustment under the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike

Price, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction (other than

the Cap Price and Number of Options) to the extent an analogous adjustment would be required to be made pursuant to the Indenture

in connection with such Merger Event or Tender Offer, subject to the second paragraph under “Method of Adjustment” and

(B) make a proportionate adjustment to the Cap Price to the extent any adjustment is made to the Strike Price pursuant to clause

(A) above (which adjustment, for the avoidance of doubt, shall not prohibit the Calculation Agent from making any further adjustment

to the Cap Price in accordance with, and subject in all respects to, the provisions of “Consequences of Announcement Events”

below and Section 9(y) hereof) (provided that in no event shall the Strike Price be greater than the Cap Price);

provided, however, that such adjustment shall be made without regard to any adjustment to the “Conversion Rate”

(as such term is defined in the Indenture) pursuant to any Excluded Provision; provided, further, that if, with respect

to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes (or, at the option of a holder of Shares,

may include) shares of an entity or person that is not a corporation or is not organized under the laws of the United States, any

State thereof or the District of Columbia or (ii) the Counterparty to the Transaction following such Merger Event or Tender

Offer will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia, then,

in either case, Cancellation and Payment (Calculation Agent Determination) shall apply if (A) Dealer determines in good faith

and a commercially reasonable manner at any time following the occurrence of such Merger Event or Tender Offer that (x) such

Merger Event or Tender Offer has had or will have an adverse effect on Dealer’s rights and obligations under the Transaction

or (y) Dealer will incur or has incurred an increased (as compared with circumstances existing on the Trade Date) amount of

tax, duty, expense or fee to (1) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or

asset(s) constituting a commercially reasonable hedge position in respect of the economic risk of entering into and performing

its obligations with respect to the Transaction or (2) realize, recover or remit the proceeds of any transaction(s) or

asset(s) constituting a commercially reasonable hedge position in respect of the economic risk of entering into and performing

its obligations with respect to the Transaction or (B) Dealer determines, in its good faith and reasonable judgment, that it

will not be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures,

applicable to Dealer (so long as such policies or procedures have been adopted by Dealer in good faith and are generally applicable

in similar situations and applied in a non-discriminatory manner and consistently to transactions similar to the Transaction); provided,

further, that, for the avoidance of doubt, adjustments shall be made pursuant to the provisions set forth above regardless

of whether any Merger Event or Tender Offer gives rise to an Early Conversion.

Consequences of Announcement

Events:

Modified Calculation Agent Adjustment as set forth in Section 12.3(d) of

the Equity Definitions; provided that, in respect of an Announcement Event, (x) references to “Tender Offer”

shall be replaced by references to “Announcement Event” and references to “Tender Offer Date” shall be replaced

by references to “date of such Announcement Event”, (y) the phrase “exercise, settlement, payment or any other

terms of the Transaction (including, without limitation, the spread)” shall be replaced with the phrase “Cap Price (provided

that in no event shall the Cap Price be less than the Strike Price)” and the words “whether within a commercially reasonable

(as determined by the Calculation Agent) period of time prior to or after the Announcement Event,” shall be inserted prior

to the word “which” in the seventh line, and (z) for the avoidance of doubt, the Calculation Agent shall determine

whether the relevant Announcement Event has had a material economic effect on the Transaction (and, if so, shall, acting in good

faith and in a commercially reasonable manner, adjust the Cap Price accordingly) on one or more occasions on or after the date of

the Announcement Event up to, and including, the Expiration Date, any Early Termination Date and/or any other date of cancellation,

it being understood that (1) any adjustment in respect of an Announcement Event shall take into account any earlier adjustment

relating to the same Announcement Event and (2) such adjustment shall be made without duplication of any other adjustment hereunder.

An Announcement Event shall be an “Extraordinary Event” for purposes of the Equity Definitions, to which Article 12

of the Equity Definitions, as modified in this paragraph, is applicable.

Announcement Event:

(i) The public announcement by the Issuer, any subsidiary or

agent of the Issuer or any Valid Third Party Entity of (x) any transaction or event that, if completed, would constitute a Merger

Event or Tender Offer, (y) any potential acquisition or disposition by Issuer and/or its subsidiaries where the aggregate consideration

exceeds 35% of the market capitalization of Issuer as of the date of such announcement (an “Acquisition Transaction”)

or (z) the intention to enter into a Merger Event or Tender Offer or an Acquisition Transaction, (ii) the public announcement

by Issuer of an intention to solicit or enter into, or to explore strategic alternatives or other similar undertaking that may include,

a Merger Event or Tender Offer or an Acquisition Transaction or (iii) any subsequent public announcement by any entity described

in clause (i) above of a change to a transaction or intention that is the subject of an announcement of the type described in

clause (i) or (ii) of this sentence (including, without limitation, a new announcement, whether or not by the same party,

relating to such a transaction or intention or the announcement of a withdrawal from, or the abandonment or discontinuation of, such

a transaction or intention), as determined by the Calculation Agent in good faith and a commercially reasonable manner. For the avoidance

of doubt, the occurrence of an Announcement Event with respect to any transaction or intention shall not preclude the occurrence

of a later Announcement Event with respect to such transaction or intention. For purposes of this definition of “Announcement

Event,” (A) “Merger Event” shall mean such term as defined under Section 12.1(b) of the Equity Definitions

(but, for the avoidance of doubt, the remainder of the definition of “Merger Event” in Section 12.1(b) of the

Equity Definitions following the definition of “Reverse Merger” therein shall be disregarded), (B) “Tender

Offer” shall mean such term as defined under Section 12.1(d) of the Equity Definitions, except that Section 12.1(d) of

the Equity Definitions is hereby amended by replacing “10%” with “25%” in the third line thereof, and (C) all

references to “voting shares” in Sections 12.1(d), 12.1(e) and 12.1(l) of the Equity Definitions shall be deemed

to be references to “Shares”.

Valid Third Party Entity:

In respect of any transaction, any third party that has a bona fide intent to

enter into or consummate such transaction, as determined by the Calculation Agent in good faith and a commercially reasonable manner

(it being understood and agreed that in determining whether such third party has such a bona fide intent, the Calculation Agent may

take into consideration the effect of the relevant announcement by such third party on the Shares and/or options relating to the

Shares).

Nationalization, Insolvency

or Delisting:

Cancellation and Payment (Calculation Agent Determination); provided

that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting

if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the

New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq Global Market (or their respective successors); if the Shares

are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The Nasdaq Global Select Market or The Nasdaq

Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.

“provided that in the case of clause (Y) hereof, the

consequence of such law, regulation or interpretation is applied consistently by Dealer to all similar transactions in a non-discriminatory

manner;” after the semi-colon in the last line thereof; and

provided, further, that no event or set of events shall constitute a Change in Law for the purposes of Section 12.9(a)(ii)(Y)

to the extent such event or events resulted solely from the deterioration of the creditworthiness of the Hedging Party; and provided,

further, that in the case of any Change in Law described in clause (Y) of Section 12.9(a)(ii) of the Equity Definitions, the

consequences provided with respect to “Increased Cost of Hedging”

of Delaware).

(g) [Counterparty has received, read and understands

the OTC Options Risk Disclosure Statement and a copy of the most recent disclosure pamphlet

prepared by The Options Clearing Corporation entitled “Characteristics and Risks of

9. Other

Provisions.

(a) Opinions. Counterparty shall

deliver to Dealer an opinion of counsel, dated as of the Premium Payment Date, with respect

to the matters set forth in Section 3(a) of the Agreement and Section 8(a) of

this Confirmation, subject to customary assumptions, limitations, exceptions and qualifications.

Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of

the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of

the Agreement.

19 Include for applicable Dealers.

(b) Repurchase Notices. Counterparty

shall, no later than one Exchange Business Day following the day on which Counterparty effects any repurchase of Shares, give Dealer

a written notice (which, for the avoidance of doubt, may be by email) of such repurchase (a “Repurchase Notice”) if

following such repurchase, the number of outstanding Shares as determined on such day is (i) less than [__]20

million (in the case of the first such notice) or (ii) thereafter more than [__]21

million less than the number of Shares included in the immediately preceding Repurchase Notice; provided that, with respect to

any repurchase of Shares pursuant to a plan under Rule 10b5-1 under the Exchange Act, Counterparty may elect to satisfy such requirement

by giving Dealer written notice of the entry into such plan on the date of such entry, the maximum number of Shares that may be repurchased

thereunder and the approximate dates or periods during which such repurchases may occur (with such maximum number of Shares deemed repurchased

on the date of such notice for purposes of this Section 9(b)), in each case so long as such written notice shall not contain any

material non-public information with respect to the Issuer or the Shares. Counterparty agrees to indemnify and hold harmless Dealer and

its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified

Person”) from and against any and all commercially reasonable losses (including losses relating to Dealer’s commercially

reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including

without limitation, any forbearance from hedging activities or cessation of hedging activities and any commercially reasonable losses

in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and commercially reasonable expenses

(including reasonable and documented out-of-pocket attorney’s fees of one outside counsel in each relevant jurisdiction), joint

or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase

Notice when and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified

Persons for any commercially reasonable and documented out-of-pocket legal or other expenses incurred in connection with investigating,

preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding

(including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person

as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified

Person shall, within a commercially reasonable period of time, notify Counterparty in writing, and Counterparty, upon request of the

Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any

others Counterparty may designate in such proceeding and shall pay the commercially reasonable and documented out-of-pocket fees and

expenses of such counsel related to such proceeding. Counterparty shall be relieved from liability to the extent that any Indemnified

Person fails to notify Counterparty within a commercially reasonable period of time of any action commenced against it in respect of

which indemnity may be sought hereunder (it being understood that any such notice delivered within 30 calendar days of the commencement

of any such action shall be deemed to have been delivered promptly for such purpose), if and to the extent Counterparty is materially

prejudiced as a result thereof. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph

that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty

agrees to indemnify any Indemnified Person from and against any commercially reasonable loss or liability by reason of such settlement

or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending

or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party

and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of

such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory

to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient

in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such

Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses,

claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights

or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements

contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction. Counterparty

will not be liable under this indemnity provision to the extent any loss, claim, damage, liability or expense is conclusively found in

a final and non-appealable judgment by a court of competent jurisdiction to have resulted from Dealer’s gross negligence or willful

misconduct.

20 Insert the number of Shares outstanding

that would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares underlying

any additional transaction if the greenshoe is exercised in full) to increase by 0.5%. To be determined based on Dealer with highest

Applicable Percentage, taking into account any existing call spreads.

21 Insert the number of Shares that,

if repurchased, would cause Dealer’s current position in the Shares underlying the Transaction (including the number of Shares

underlying any additional transaction if the greenshoe is exercised in full) to increase by a further 0.5% from the threshold for the

first Repurchase Notice. To be determined based on Dealer with highest Applicable Percentage, taking into account any existing call spreads.

is not on the Trade Date engaged in a distribution, as such term is used in Regulation M

under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),

of any securities of Counterparty, other than a distribution meeting the requirements of

the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M.

Counterparty shall not, until the second Scheduled Trading Day immediately following the

Effective Date, engage in any such distribution.

(d) No Manipulation. Counterparty

is not entering into the Transaction to create actual or apparent trading activity in the

Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress

or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable

for the Shares) in violation of the Exchange Act.

(e) Transfer or Assignment.

(i) Counterparty shall have the right to transfer

or assign its rights and obligations hereunder with respect to all, but not less than all,

of the Options hereunder (such Options, the “Transfer Options”); provided

that such transfer or assignment shall be subject to reasonable conditions that Dealer may

impose, including but not limited to, the following conditions:

(A) With respect to any Transfer Options,

Counterparty shall not be released from its notice and indemnification obligations pursuant

to Section ‎9(b) of this Confirmation or any obligations under Section ‎9(n) or

‎9(s) of this Confirmation;

(B) Any Transfer Options shall only be transferred

or assigned to a third party that is a United States person (as defined in Section 7701(a)(30)

of the Internal Revenue Code of 1986, as amended (the “Code”));

on terms, including any reasonable undertakings by such third party (including, but not limited

to, an undertaking with respect to compliance with applicable securities laws in a manner

that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under

applicable securities laws) and execution of any documentation and delivery of legal opinions

with respect to securities laws and other matters by such third party and Counterparty, as

are reasonably requested by and reasonably satisfactory to Dealer;

(D) Dealer will not, as a result of such transfer

or assignment, (1) be required to pay or deliver to the transferee or assignee on any

payment date or delivery date, as applicable, an amount under Section 2(d)(i)(4) of

the Agreement greater than an amount that Dealer would have been required to pay or deliver

to Counterparty in the absence of such transfer or assignment or (2) receive from the

transferee or assignee on any payment date or delivery date, as applicable, an amount (after

taking into account amounts required to be paid or delivered by the transferee or assignee

under Section 2(d)(i)(4) of the Agreement, as well as any amounts withheld) that

is less than the amount that Dealer would have received from Counterparty in the absence

of such transfer or assignment;

(E) No Event of Default, Potential Event of

Default or Termination Event will occur as a result of such transfer or assignment;

(F) Without limiting the generality of clause

‎(B), Counterparty shall cause the transferee or assignee to make such Payee Tax Representations

and to provide such tax documentation as may be reasonably requested by Dealer to permit

Dealer to determine that the results described in clause ‎(D) and, if applicable,

clause ‎(E) will not occur upon or after such transfer or assignment; and

(G) Counterparty shall be responsible for

all commercially reasonable costs and expenses, including commercially reasonable counsel

fees, incurred by Dealer in connection with such transfer or assignment.

(ii) Dealer may transfer or assign all or any

part of its rights or obligations under the Transaction (A) without Counterparty’s

consent, to any affiliate of Dealer (1) that has a long-term issuer rating that is equal

to or better than Dealer’s credit rating at the time of such transfer or assignment,

or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary

guarantee in a form used by Dealer or Dealer’s ultimate parent, as applicable, generally

for similar transactions, by Dealer or Dealer’s ultimate parent or (B) with Counterparty’s

prior written consent (such consent not to be unreasonably withheld), to any other recognized

dealer in transactions of the same type as the Transaction with a long-term issuer rating

equal to or better than the lesser of (1) the credit rating of Dealer at the time of

the transfer or assignment and (2) A- by Standard & Poor’s Financial

Services LLC or its successor (“S&P”), or A3 by Moody’s Investors

Service, Inc. (“Moody’s”) or, if either S&P or Moody’s

ceases to rate such debt, at least an equivalent rating or better by a substitute rating

agency mutually agreed by Counterparty and Dealer; provided, however, Dealer

may transfer or assign pursuant to this paragraph only if (A) the transferee or assignee

is a “dealer in securities” within the meaning of Section 475(c)(1) of

the Code or such transfer or assignment does not constitute a “deemed exchange”

by Counterparty within the meaning of Section 1001 of the Code, (B) Counterparty

shall be entitled to a payment or a delivery, as applicable, on any payment date or delivery

date, that is not less than the payment or delivery Counterparty would have received in the

absence of such transfer or assignment, taking into account any deduction or withholding

as well as amounts payable by such transferee under Section 2(d)(i) of the Agreement,

except to the extent such deduction or withholding results from a Change in Tax Law occurring

after the date of such transfer or assignment, (C) no Event of Default, Potential Event

of Default or Termination Event will occur as a result of such transfer or assignment, (D) Counterparty

would not, at the time and as a result of such transfer or assignment, reasonably be expected

to become subject to any law, regulation or similar requirement to which it would not otherwise

have been subject absent such transfer or assignment, (E) Dealer shall have provided

prompt written notice to Counterparty of such transfer, (F) any side letters or other

agreements modifying the Transaction shall simultaneously be transferred or assigned to the

transferee and (G) Dealer shall cause the transferee or assignee to provide Counterparty

with a duly executed and properly completed and accurate U.S. Internal Revenue Service Form W-9

or appropriate W-8 (or successor form), as applicable, to make such Payee Tax Representations,

and provide such other tax documentation as may be reasonably requested by Counterparty to

permit Counterparty to confirm the satisfaction of the conditions in clauses (A) and

(B) of this proviso. If at any time at which (A) the Section 16 Percentage

exceeds 8.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share

Amount exceeds the Applicable Share Limit (if any applies) (any such condition described

in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer

is unable after using its commercially reasonable efforts to effect a transfer or assignment

of Options to a third party in accordance with the preceding sentence on pricing terms reasonably

acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no

Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as

an Early Termination Date with respect to a portion of the Transaction (the “Terminated

Portion”), such that following such partial termination no Excess Ownership Position

exists. In the event that Dealer so designates an Early Termination Date with respect to

a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement

as if (1) an Early Termination Date had been designated in respect of a Transaction

having terms identical to the Transaction and a Number of Options equal to the number of

Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party

with respect to such partial termination and (3) the Terminated Portion were the sole

Affected Transaction (and, for the avoidance of doubt, the provisions of Section ‎9(l) of

this Confirmation shall apply to any amount that is payable by Dealer to Counterparty pursuant

to this sentence as if Counterparty was not the Affected Party). Dealer shall notify Counterparty

of an Excess Ownership Position with respect to which it intends to seek a transfer or assignment

as soon as reasonably practicable after becoming aware of such an Excess Ownership Position.

The “Section 16 Percentage” as of any day is the fraction, expressed

as a percentage, (A) the numerator of which is the number of Shares that Dealer and

any of its affiliates or any other person subject to aggregation with Dealer for purposes

of the “beneficial ownership” test under Section 13 of the Exchange Act,

or any “group” (within the meaning of Section 13 of the Exchange Act) of

which Dealer is or may be deemed to be a part beneficially owns (within the meaning of Section 13

of the Exchange Act), without duplication, on such day (or, to the extent that for any reason

the equivalent calculation under Section 16 of the Exchange Act and the rules and

regulations thereunder results in a higher number, such higher number) and (B) the denominator

of which is the number of Shares outstanding on such day. The “Option Equity Percentage”

as of any day is the fraction, expressed as a percentage, (A) the numerator of which

is the sum of (1) the product of the Number of Options and the Option Entitlement and

(2) the aggregate number of Shares underlying any other call option transaction sold

by Dealer to Counterparty, and (B) the denominator of which is the number of Shares

outstanding. The “Share Amount” as of any day is the number of Shares

that Dealer and any person whose ownership position would be aggregated with that of Dealer

(Dealer or any such person, a “Dealer Person”) under any law, rule, regulation,

regulatory order or organizational documents or contracts of Counterparty that are, in each

case, applicable to ownership of Shares (excluding those arising under Section 13 or

16 of the Exchange Act, in each case, as in effect on the Trade Date, the “Applicable

Restrictions”), owns, beneficially owns, constructively owns, controls, holds the

power to vote or otherwise meets a relevant definition of ownership under any Applicable

Restriction, as determined by Dealer in its reasonable discretion. The “Applicable

Share Limit” means a number of Shares equal to (A) the minimum number of Shares

that, in Dealer’s reasonable judgment based on advice of counsel, could give rise to

reporting or registration obligations (except for filings on Form 13F, Schedule 13D

or Schedule 13G under the Exchange Act, in each case, as in effect on the Trade Date) or

other requirements (including obtaining prior approval from any person or entity, but excluding

any such requirements that can be satisfied without administrative or operational burden

or cost to Dealer) of a Dealer Person, or could result in an adverse effect on a Dealer Person,

under any Applicable Restriction, as determined by Dealer in its reasonable discretion, and

based on advice of counsel with respect to any legal obligations or legal requirements, minus

(B) 1% of the number of Shares outstanding. Dealer shall provide Counterparty with written

notice of any transfer or assignment on the date of or as promptly as practicable after the

date of such transfer or assignment.

(iii) Notwithstanding any other provision in

this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive

or deliver any Shares or other securities, or make or receive any payment in cash, to or

from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive

or deliver such Shares or other securities, or to make or receive such payment in cash, and

otherwise to perform Dealer’s obligations in respect of the Transaction and any such

designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty

to the extent of any such performance.

(f) Staggered Settlement. If

upon advice of counsel with respect to applicable legal and regulatory requirements, including

any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably

determines that it would not be practicable or advisable to deliver, or to acquire Shares

to deliver, any or all of the Shares to be delivered by Dealer on any Settlement Date for

the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date

(a “Nominal Settlement Date”), elect to deliver any Shares due to be delivered

on two or more dates (each, a “Staggered Settlement Date”) or at two or

more times on the Nominal Settlement Date as follows:

(i) in such notice, Dealer will specify to Counterparty

the related Staggered Settlement Dates (each of which will be on or prior to such Nominal

Settlement Date and in no event shall any Staggered Settlement Date be a date later than

the final Expiration Date) or delivery times and how it will allocate the Shares it is required

to deliver hereunder on the Settlement Date among the Staggered Settlement Dates or delivery

times; and

(ii) the aggregate number of Shares that Dealer

will deliver to Counterparty hereunder on all such Staggered Settlement Dates and at all

such delivery times will equal the number of Shares that Dealer would otherwise be required

to deliver on such Nominal Settlement Date.

(g) Dividends. If, at any time

during the period from, and including, the Effective Date to, but excluding, the Expiration

Date, (i) an ex-dividend date (an “Ex-Dividend Date”) for a regular

quarterly cash dividend occurs with respect to the Shares, and that dividend is less than

the Regular Dividend on a per Share basis or (ii) no Ex-Dividend Date for a regular

quarterly cash dividend occurs with respect to the Shares in any quarterly dividend period

of Counterparty, then the Calculation Agent will adjust the Cap Price to preserve the fair

value of the Options to Dealer after taking into account such dividend or lack thereof. “Regular

Dividend” shall mean USD 0.10 per Share per quarter. Upon any adjustment to the

“Initial Dividend Threshold” (as defined in the Indenture) for the Convertible

Notes pursuant to the Indenture, the Calculation Agent will make a corresponding adjustment

to the Regular Dividend for the Transaction.

(h) [Conduct Rules. Each party

acknowledges and agrees to be bound by the Conduct Rules of the Financial Industry Regulatory

Authority applicable to transactions in options, and further agrees not to violate the position

and exercise limits set forth therein.]22[Reserved.]

(i) Additional Termination Events.

(i) Notwithstanding anything to the contrary

in this Confirmation, upon any Early Conversion in respect of which a “Notice of Conversion”

(as such term is defined in the Indenture) that is effective as to Counterparty has been

delivered by the relevant converting “Holder” (as such term is defined in the

Indenture):

(A) Counterparty shall, within five Scheduled

Trading Days of the Conversion Date for such Early Conversion, provide written notice (an

“Early Conversion Notice”) to Dealer specifying the number of Convertible

Notes surrendered for conversion on such Conversion Date (such Convertible Notes, the “Affected

Convertible Notes”) and the settlement date for the conversion of such Affected

Convertible Notes[; provided that, any “Early Conversion Notice” delivered

to Dealer pursuant to the Base Call Option Confirmation shall deemed to be an Early Conversion

Notice pursuant to this Confirmation and the terms of such Early Conversion Notice shall

apply, mutatis mutandis, to this Confirmation]23;

provided that, notwithstanding the foregoing, in the case of any Early Conversion

with a Conversion Date occurring on or after the date that Counterparty issues a “Redemption

Notice” (as such term is defined in the Indenture) and prior to 5:00 p.m. (New

York City time) on the Scheduled Valid Day immediately preceding the related “Redemption

Date” (as such term is defined in the Indenture) (any such period, a “Redemption

Period”, and any such conversion, a “Redemption Conversion”),

Counterparty shall deliver such Early Conversion Notice no later than five Scheduled Trading

Days after the last day of such Redemption Period and such Early Conversion Notice shall

instead specify the aggregate number of Convertible Notes surrendered for conversion during

the Redemption Period[; provided further that any “Early Conversion Notice”

delivered to Dealer pursuant to the Base Call Option Confirmation shall deemed to be an Early

Conversion Notice pursuant to this Confirmation and the terms of such Early Conversion Notice

shall apply, mutatis mutandis, to this Confirmation]24;

22 Include for applicable Dealers.

23 Insert for Additional Call Option Confirmation.

24 Insert for Additional Call Option Confirmation.

(B) the giving of an Early Conversion Notice

pursuant to subclause (A) above shall constitute an Additional Termination Event as

provided in this Section 9(i)‎(i);

Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which

Exchange Business Day shall be on or as promptly as reasonably practicable after the settlement

date for the conversion of the Affected Convertible Notes (or, in the case of a Redemption

Conversion, the later of (x) the settlement date for the conversion of the Affected

Convertible Notes and (y) the Scheduled Trading Day immediately following the date of

the relevant Early Conversion Notice)) with respect to the portion of the Transaction corresponding

to a number of Options (the “Affected Number of Options”) equal to the

lesser of (x) the number of Affected Convertible Notes [minus the “Affected

Number of Options” (as defined in the Base Call Option Confirmation), if any, that

relate to such Affected Convertible Notes (and for the purposes of determining whether any

Options under this Confirmation or under the Base Call Option Confirmation will be among

the Affected Number of Options hereunder or under, and as defined in, the Base Call Option

Confirmation, the Affected Convertible Notes specified in such Early Conversion Notice shall

be allocated first to the Base Call Option Confirmation until all Options thereunder are

exercised or terminated)]25 and (y) the

Number of Options as of the Conversion Date for such Early Conversion (or, in the case of

a Redemption Conversion, as of the last day of the relevant Redemption Period);

(D) any payment hereunder with respect to

such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an

Early Termination Date had been designated in respect of a Transaction having terms identical

to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty

were the sole Affected Party with respect to such Additional Termination Event and (z) the

terminated portion of the Transaction were the sole Affected Transaction (and, for the avoidance

of doubt, the provisions of Section 9(l) of this Confirmation shall apply to any

amount that is payable by Dealer to Counterparty pursuant to this Section 9(h)(i)(D) as

if, solely for the purpose of electing the settlement method, Counterparty were not the Affected

Party); provided that the amount payable with respect to such termination shall not

be greater than (1) the Applicable Percentage, multiplied by (2) the Affected

Number of Options, multiplied by (3) (x) the sum of (i) the amount

of cash paid to the “Holder” (as such term is defined in the Indenture) of an

Affected Convertible Note upon conversion of such Affected Convertible Note and (ii) the

number of Shares delivered (if any) to the “Holder” (as such term is defined

in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible

Note, multiplied by the Applicable Limit Price on the relevant date of payment, minus

(y) the Synthetic Instrument Adjusted Issue Price per Convertible Note, as determined

by the Calculation Agent in good faith and in a commercially reasonable manner. “Synthetic

Instrument Adjusted Issue Price per Convertible Note” shall mean the amount determined

by the Calculation Agent utilizing the numbers in the table set forth below based on the

date of payment of the amount due with respect to the relevant Affected Number of Options

(the “Affected Unwind Date”). If the Affected Unwind Date is not listed

below, the amount in the preceding sentence shall be determined by the Calculation Agent

utilizing the numbers in the table below using a linear interpolation between the lower and

higher Synthetic Instrument Adjusted Issue Prices per Convertible Note for the dates immediately

preceding and immediately following the Affected Unwind Date. For the avoidance of doubt,

any payment pursuant to this paragraph shall be subject to Section 9(l) of this

Confirmation;

(E) for the avoidance of doubt, in determining

the amount payable in respect of such Affected Transaction pursuant to Section 6 of

the Agreement, the Calculation Agent shall assume that (x) the relevant Early Conversion

and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or

on behalf of Counterparty leading thereto had not occurred, (y) no adjustments to the

“Conversion Rate” (as such term is defined in the Indenture) have occurred pursuant

to any Excluded Provision and (z) the corresponding Convertible Notes remain outstanding;

and

(F) the Transaction shall remain in full force

and effect, except that, as of the Conversion Date for such Early Conversion, the Number

of Options shall be reduced by the Affected Number of Options.

(ii) Notwithstanding anything to the contrary

in this Confirmation, if an event of default with respect to Counterparty occurs under the

terms of the Convertible Notes as set forth in Section 6.01 of the Indenture and the

Convertible Notes are declared due and payable as a result thereof, then such event of default

shall constitute an Additional Termination Event applicable to the Transaction and, with

respect to such Additional Termination Event, (A) Counterparty shall be deemed to be

the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction

and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant

to Section 6(b) of the Agreement.

(iii) Notwithstanding anything to the contrary

in this Confirmation, the occurrence of an Amendment Event shall constitute an Additional

Termination Event applicable to the Transaction and, with respect to such Additional Termination

Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the

Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party

entitled to designate an Early Termination Date pursuant to Section 6(b) of the

Agreement. “Amendment Event” means that Counterparty amends, modifies,

supplements, waives or obtains a waiver in respect of any term of the Indenture or the Convertible

Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty,

redemption right of Counterparty, any term relating to conversion of the Convertible Notes

(including changes to the conversion rate, conversion rate adjustment provisions, conversion

settlement dates or conversion conditions), or any term that would require consent of the

holders of not less than 100% of the principal amount of the Convertible Notes to amend (other

than, in each case, any amendment or supplement (x) pursuant to Section 10.01(k) of

the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the

description of Convertible Notes in the Offering Memorandum or (y) pursuant to Section 10.01(a) or 14.07

of the Indenture), in each case, without the consent of Dealer.

(iv) Within five Scheduled Trading Days following

any Repayment Event (as defined below) (or, in the case of a Repayment Event as described in the following clause (i)(y) or (i)(z),

on the date of such Repayment Event), Counterparty (i) shall (solely to the extent that such Repayment Event results directly from

(x) a “Fundamental Change” (as such term is defined in the Indenture), (y) a “Cleanup Redemption” (as

defined in the Indenture) or (z) an “Optional Redemption” (as such term is defined in the Indenture)), and (ii) otherwise

may, but shall not be obligated to, notify Dealer of such Repayment Event and the aggregate principal amount of Convertible Notes subject

to such Repayment Event (any such notice, a “Repayment Notice”); provided that (1) in the case of clause

(i)(y) or (i)(z) only, such Repayment Notice shall contain the representation and warranty that Counterparty is not giving

such notification on the basis of material non-public information with respect to Counterparty or the Shares and (2) in the case

of clause (ii) only, such Repayment Notice shall contain the representation and warranty that Counterparty is not, on the date thereof,

aware of any material non-public information with respect to Counterparty or the Shares[; provided, further, that any “Repayment

Notice” delivered to Dealer pursuant to the Base Call Option Confirmation shall deemed to be a Repayment Notice pursuant to this

Confirmation and the terms of such Repayment Notice shall apply, mutatis mutandis, to this Confirmation]26.

The receipt by Dealer from Counterparty of any Repayment Notice, within the applicable time period (or on the applicable date) set forth

in the preceding sentence, shall constitute an Additional Termination Event as provided in this paragraph, it being understood that no

Repayment Event shall constitute an Additional Termination Event hereunder unless Dealer has so received such Repayment Notice. Upon

receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of such Repayment Notice (which

in no event shall be earlier than the date on which the relevant Repayment Event occurs or is consummated and which shall be on or as

soon as reasonably practicable after the settlement date for the relevant Repurchase Event) as an Early Termination Date with respect

to the portion of the Transaction corresponding to a number of Options (the “Repayment Options”) equal to the lesser

of (A) [(x)] the aggregate principal amount of such Convertible Notes specified in such Repayment Notice, divided by USD

1,000, [minus (y) the number of “Repayment Options” (as defined in the Base Call Option Confirmation), if any,

that relate to such Convertible Notes (and for the purposes of determining whether any Options under this Confirmation or under the Base

Call Option Confirmation will be among the Repayment Options hereunder or under, and as defined in, the Base Call Option Confirmation,

the Convertible Notes specified in such Repayment Notice shall be allocated first to the Base Call Option Confirmation until all Options

thereunder are exercised or terminated),]27 and (B) the Number of Options as of

the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of

Repayment Options. Any payment hereunder with respect to such termination (the “Repayment Unwind Payment”) shall be

calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction

having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were

the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were

the sole Affected Transaction; provided that, in the event of a Repayment Event resulting from a “Fundamental Change”

(as such term is defined in the Indenture), a “Cleanup Redemption” (as defined in the Indenture) or an “Optional Redemption”

(as such term is defined in the Indenture), the Repayment Unwind Payment shall not be greater than (1) the number of Repayment Options

multiplied by (2) the product of (A) the Applicable Percentage and (B) (x) the amount paid by Counterparty

per Convertible Note in connection with the relevant Repayment Event pursuant to the relevant sections of the Indenture minus

(y) the Synthetic Instrument Adjusted Issue Price per Convertible Note, as determined by the Calculation Agent in good faith and

in a commercially reasonable manner, as set forth in Section 9(i)(i)(D) above based on the date of payment of the relevant

Repayment Unwind Payment (the “Repayment Date”) as if such Repayment Date were the Affected Unwind Date (including

for purposes of the second to last sentence of such Section 9(i)(i)(D)). For the avoidance of doubt, solely for purposes of calculating

the amount payable pursuant to Section 6 of the Agreement pursuant to the immediately preceding sentence, Dealer shall assume that

the relevant Repayment Event (and, if applicable, the related Fundamental Change) had not occurred. “Repayment Event”

means that (i) any Convertible Notes are repurchased and cancelled in accordance with the Indenture (whether in connection with

or as a result of a Fundamental Change, upon redemption or for any other reason) by Counterparty or any of its subsidiaries, (ii) any

Convertible Notes are delivered to Counterparty or any of its subsidiaries in exchange for delivery of any property or assets of such

party (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the

Convertible Notes (for any reason other than as a result of an acceleration of the Convertible Notes that results in an Additional Termination

Event pursuant to the preceding Section 9(i)(ii)), or (iv) any Convertible Notes are exchanged by or for the benefit of the

holders thereof for any other securities of Counterparty or any of its subsidiaries (or any other property, or any combination thereof)

pursuant to any exchange offer or similar transaction. For the avoidance of doubt, any conversion of Convertible Notes (whether into

cash, Shares, reference property or any combination thereof) pursuant to the terms of the Indenture shall not constitute a Repayment

Event. In addition, Counterparty acknowledges, based on advice of outside counsel, its responsibilities under applicable securities laws,

including, in particular, Sections 9 and 10(b) of the Exchange Act and the rules and regulations thereunder in respect of the

Repayment Event, including, without limitation, the delivery of a Repayment Notice hereunder.

(j) Amendments to Equity Definitions;

Agreement.

(i) Section 11.2(e)(vii) of the Equity

Definitions is hereby amended by deleting the words “that may have a diluting or concentrative

effect on the theoretical value of the relevant Shares” and replacing them with the

words “that is the result of a corporate event involving the Issuer or its securities

that has, in the commercially reasonable judgment of the Calculation Agent, a material economic

effect on the Shares or the Options; provided that such corporate event involving

the Issuer is not based on (a) an observable market, other than the market for Issuer’s

own stock or (b) an observable index, other than an index calculated and measured solely

by reference to Issuer’s own operations.”

(ii) Section 12.9(b)(i) of the Equity

Definitions is hereby amended by inserting the phrase “; provided that Counterparty

may only elect to terminate the Transaction upon the occurrence of a Change in Law or Insolvency

Filing if concurrently with electing to terminate the Transaction, Counterparty represents

and warrants to Dealer in writing that (i) it is not aware of any material nonpublic

information with respect to Counterparty or the Shares and (ii) it is not making such

election as part of a plan or scheme to evade compliance with the U.S. federal securities

laws” at the end thereof.

(iii) Section 12.9(b)(vi) of the Equity

Definitions is hereby amended by (1) adding the word “or” immediately before

subsection (B), (2) deleting the comma at the end of subsection (A), (3) deleting

(iv) Section 12(a) of the Agreement

is hereby amended by (1) deleting the phrase “or email” in the third line

thereof and (2) deleting the phrase “or that communication is delivered (or attempted)

or received, as applicable, after the close of business on a Local Business Day” in

the final clause thereof.

(k) No Netting and Setoff. The

provisions of Section 2(c) of the Agreement shall not apply to the Transaction.

Notwithstanding any provision of the Agreement and this Confirmation (including without limitation

this Section 9(k)) or any other agreement between the parties to the contrary, each

party waives any and all rights it may have to set off obligations arising under the Agreement

and the Transaction against other obligations between the parties, whether arising under

any other agreement, applicable law or otherwise.

(l) Alternative Calculations and Payment

on Early Termination and on Certain Extraordinary Events. If (a) an Early Termination

Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated

with respect to the Transaction or (b) the Transaction is cancelled or terminated upon

the occurrence of an Extraordinary Event (except as a result of (i) a Nationalization, Insolvency

or Merger Event in which the consideration to be paid to all holders of Shares consists solely

of cash, (ii) an Announcement Event, Merger Event or Tender Offer that is within Counterparty’s

control, or (iii) an Event of Default in which Counterparty is the Defaulting Party

or a Termination Event in which Counterparty is the sole Affected Party other than an Event

of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of

the Agreement or a Termination Event of the type described in Section 5(b) of the

Agreement, in each case that resulted from an event or events outside Counterparty’s

control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of

the Agreement or any Cancellation Amount pursuant to Article 12 of the Equity Definitions

(any such amount, a “Payment Obligation”), then Dealer shall satisfy the

Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty

gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled

Trading Day, no later than 12:00 p.m. (New York City time) on the date of the Announcement

Event, Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency

or Delisting), Early Termination Date or date of cancellation, as applicable, of its election

that the Share Termination Alternative shall not apply, and (b) Counterparty acknowledges,

as of the date of such election, its responsibilities under applicable securities laws, and

in particular Section 9 and Section 10(b) of the Exchange Act and the rules and

regulations thereunder, with respect to such election, in which case the provisions of Section 12.7

or Section 12.9 of the Equity Definitions, or the provisions of Section 6(d)(ii) of

the Agreement, as the case may be, shall apply.

Termination Alternative:

If applicable, Dealer shall deliver

to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when

the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii)

and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty

free of payment.

Termination Delivery Property:

A number of Share Termination Delivery Units,

as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price. The Calculation

Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount

of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

Termination Delivery Unit:

One Share or, if the Shares have changed into

cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger

Event (any such cash or other property, the “Exchange Property”), a unit consisting of the type and amount of

such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration

in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation

Agent.

Termination Unit Price:

The value of property contained in

one Share Termination Delivery Unit, as determined by the Calculation Agent by commercially reasonable means and notified by the

Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree

that in determining the Share Termination Unit Price the Calculation Agent may consider the purchase price paid in connection with

the purchase of Share Termination Delivery Property that was purchased in connection with the delivery of the Share Termination Delivery

Units.

Failure

to Deliver:

Applicable

Other

Applicable Provisions:

If Share Termination Alternative is applicable,

the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite

the caption “Representation and Agreement” in Section 2 of this Confirmation will be applicable, except that all references

in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and

all references to “Shares” shall be read as references to “Share Termination Delivery Units”. “Share

Termination Settled” in relation to the Transaction means that Share Termination Alternative is applicable to the Transaction.

(m) Waiver of Jury Trial. Each

party waives, to the fullest extent permitted by applicable law, any right it may have to

a trial by jury in respect of any suit, action or proceeding relating to the Transaction.

Each party (i) certifies that no representative, agent or attorney of either party has

represented, expressly or otherwise, that such other party would not, in the event of such

a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges

that it and the other party have been induced to enter into the Transaction, as applicable,

by, among other things, the mutual waivers and certifications provided herein.

(n) Registration. Counterparty

hereby agrees that if, in the good faith reasonable judgment of Dealer, based on the advice

of counsel, the Shares acquired and held by Dealer for the purpose of effecting a commercially

reasonable hedge of its obligations pursuant to the Transaction (“Hedge Shares”)

cannot be sold in the public market by Dealer without registration under the Securities Act

(other than any such Hedge Shares that were, at the time of acquisition by Dealer, “restricted

securities” (as defined in Rule 144 under the Securities Act)), Counterparty shall,

at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered

offering, make available to Dealer an effective registration statement under the Securities

Act and enter into an agreement, in form and substance commercially reasonably satisfactory

to Dealer, substantially in the form of an underwriting agreement for a registered secondary

offering of substantially similar size and in a similar industry (provided, however,

that if Dealer, in its reasonable discretion, is not satisfied with access to due diligence

materials, the results of its due diligence investigation, or the procedures and documentation

for the registered offering referred to above, then clause (ii) or clause (iii) of

this paragraph shall apply at the election of Counterparty), (ii) in order to allow

Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement

substantially similar to private placement purchase agreements customary for private placements

of equity securities of similar size and industry, in form and substance commercially reasonably

satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to

the terms of the Transaction that are necessary, in its commercially reasonable judgment,

to compensate Dealer for any commercially reasonable discount from the public market price

of the Shares incurred on the sale of Hedge Shares in a private placement) or (iii) purchase

the Hedge Shares from Dealer at the then-current market price on such Exchange Business Days,

and in the amounts and at such time(s), requested by Dealer.

(o) Tax Disclosure. Effective

from the date of commencement of discussions concerning the Transaction, Counterparty and

each of its employees, representatives, or other agents may disclose to any and all persons,

without limitation of any kind, the tax treatment and tax structure of the Transaction and

all materials of any kind (including opinions or other tax analyses) that are provided to

Counterparty relating to such tax treatment and tax structure.

(p) Right to Extend. Dealer

may postpone or add, in whole or in part, any Valid Day or Valid Days during the Settlement

Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect

to some or all of the Options hereunder, to the extent Dealer reasonably determines (and

in the case of clause (ii) below, based on the advice of counsel), that such action

is reasonably necessary or appropriate (i) to preserve Dealer’s commercially reasonable

hedging or hedge unwind activity hereunder in light of existing liquidity conditions (but

only if there is a material decrease in liquidity relative to Dealer’s expectations

on the Trade Date) or (ii) to enable Dealer to effect purchases of Shares in connection

with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in

a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty,

be in compliance with applicable legal, regulatory or self-regulatory requirements, or with

related policies and procedures applicable to Dealer (so long as such policies or procedures

are consistently applied to transactions similar to the Transaction); provided that

no such Valid Day or other date of valuation, payment or delivery may be postponed or added

more than 60 Valid Days after the original Valid Day or other date of valuation, payment

or delivery, as the case may be.

(q) Status of Claims in Bankruptcy.

Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer

rights against Counterparty with respect to the Transaction that are senior to the claims

of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty;

provided that nothing herein shall limit or shall be deemed to limit Dealer’s

right to pursue remedies in the event of a breach by Counterparty of its obligations and

agreements with respect to the Transaction; provided, further, that nothing

herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions

other than the Transaction.

(r) Securities Contract; Swap Agreement.

The parties hereto intend for (i) the Transaction to be a “securities contract”

and a “swap agreement” as defined in the Bankruptcy Code, and the parties hereto

to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6),

362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party’s

right to liquidate the Transaction and to exercise any other remedies upon the occurrence

of any Event of Default under the Agreement with respect to the other party to constitute

a “contractual right” as described in the Bankruptcy Code, and (iii) each

payment and delivery of cash, securities or other property hereunder to constitute a “margin

payment” or “settlement payment” and a “transfer” as defined

in the Bankruptcy Code.

(s) Notice of Certain Other Events.

Counterparty covenants and agrees that:

(i) promptly following the public announcement

of the results of any election by the holders of Shares with respect to the consideration

due upon consummation of any Merger Event, Counterparty shall give Dealer written notice

of the types and amounts of consideration actually received by holders of Shares pursuant

to such Merger Event (the date of such notification, the “Consideration Notification

Date”); provided that in no event shall the Consideration Notification Date

be later than the date on which such Merger Event is consummated; and

(ii) (A) Counterparty shall give Dealer

commercially reasonable advance (but in no event less than one Exchange Business Day) written

notice of the section or sections of the Indenture and, if applicable, the formula therein,

pursuant to which any adjustment will be made to the Convertible Notes in connection with

any Potential Adjustment Event, Merger Event or Tender Offer and (B) promptly following

any such adjustment, Counterparty shall give Dealer written notice of the details of such

adjustment.

(t) Wall Street Transparency and Accountability

Act. In connection with Section 739 of the Wall Street Transparency and Accountability

Act of 2010 (“WSTAA”), the parties hereby agree that neither the enactment

of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment

made by WSTAA, shall limit or otherwise impair either party’s otherwise applicable

rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement,

as applicable, arising from a termination event, force majeure, illegality, increased costs,

regulatory change or similar event under this Confirmation, the Equity Definitions incorporated

herein, or the Agreement (including, but not limited to, rights arising from Change in Law,

Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality

(as defined in the Agreement)).

(u) Agreements and Acknowledgements

Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at

any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares

or other securities or buy or sell options or futures contracts or enter into swaps or other

derivative securities in order to adjust its hedge position with respect to the Transaction;

(B) Dealer and its affiliates also may be active in the market for Shares other than

in connection with hedging activities in relation to the Transaction; (C) Dealer shall

make its own determination as to whether, when or in what manner any hedging or market activities

in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate

to hedge its price and market risk with respect to the Relevant Prices; and (D) any

market activities of Dealer and its affiliates with respect to Shares may affect the market

price and volatility of Shares, as well as the Relevant Prices, each in a manner that may

be adverse to Counterparty.

(v) Early Unwind. In the event

the sale of the [“Firm Securities”]28[“Option

Securities”]29 (as defined in the Purchase

Agreement) is not consummated with the Initial Purchaser for any reason, or Counterparty

fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a) of

this Confirmation, in each case by 5:00 p.m. (New York City time) on the Premium Payment

Date, or such later date as agreed upon by the parties (the Premium Payment Date or such

later date, the “Early Unwind Date”), the Transaction shall automatically

terminate (the “Early Unwind”) on the Early Unwind Date and (i) the

Transaction and all of the respective rights and obligations of Dealer and Counterparty under

the Transaction shall be cancelled and terminated and (ii) each party shall be released

and discharged by the other party from and agrees not to make any claim against the other

party with respect to any obligations or liabilities of the other party arising out of and

to be performed in connection with the Transaction either prior to or after the Early Unwind

Date. Each of Dealer and Counterparty represents and acknowledges to the other that upon

an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and

finally discharged.

(w) Tax Matters.

(i) Withholding Tax imposed on

payments to non-U.S. counterparties under the United States Foreign Account Tax Compliance provisions of the HIRE Act. The parties

hereto agree that for the Transaction the term “Indemnifiable Tax” as defined in Section 14 of the Agreement, shall

not include (i) any Tax imposed pursuant to Sections 1471 through 1474 of the Code, as amended, any current or future regulations

or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory

legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation

of such Sections of the Code (a “FATCA Withholding Tax”) or (ii) any Tax imposed on amounts treated as dividends

from sources within the United States under Section 871(m) of the Code (or any Treasury regulations or other guidance issued

thereunder) (a “Section 871(m) Tax”). For the avoidance of doubt, a FATCA Withholding Tax and a Section 871(m) Tax

are each a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d)(i) of the

Agreement.

(ii) Tax Documentation. For

purposes of Section 4(a)(i) and (ii) of the Agreement, (i) Counterparty agrees to deliver to Dealer one duly executed

and completed United States Internal Revenue Service Form W-9 (or successor thereto) and (ii) Dealer agrees to deliver to Counterparty

one duly executed and completed United States Internal Revenue Service Form [__] (or successor thereto), in each case, (A) on

or before the date of execution of this Confirmation, (B) promptly upon learning that any such tax form previously provided by it

has become obsolete or incorrect and (C) promptly upon the reasonable request of the other party. Additionally, each party shall,

promptly upon request by the other party, provide such other tax forms and documents reasonably requested by the other party.

(iii) Payee Tax Representations.

For the purpose of Section 3(f) of the Agreement, the parties make the following representations: Counterparty is a corporation

for U.S. federal income tax purposes and is organized under the laws of the State of Delaware. Counterparty is a “U.S. person”

(as that term is used in section 1.1441-4(a)(3)(ii) of United States Treasury Regulations) for U.S. federal income tax purposes

and an exempt recipient under Treasury Regulation Section 1.6049-4(c)(1)(ii). [Dealer is [_________].]30

(x) Payment by Counterparty.

In the event that, following payment of the Premium, (i) an Early Termination Date occurs

or is designated with respect to the Transaction as a result of a Termination Event or an

Event of Default (other than an Event of Default arising under Section 5(a)(ii) or

5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated

under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer,

pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated

under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.

(y) Other Adjustments Pursuant to the

Equity Definitions. Notwithstanding anything to the contrary in the Agreement, the

Equity Definitions or this Confirmation, upon the occurrence of a Merger Date, the occurrence

of a Tender Offer Date, or declaration by Counterparty of the terms of any Potential Adjustment

Event, the Calculation Agent shall determine in good faith and in a commercially reasonable

manner whether such occurrence or declaration, as applicable, has had a material economic

effect on the Transaction, and if so, shall, in its good faith and commercially reasonable

discretion, adjust the Cap Price to account for the economic effect on the Transaction of

such occurrence or declaration (provided that in no event shall the Cap Price be less

than the Strike Price; and provided, further, that any adjustment to the Cap

Price made pursuant to this section shall be made without duplication of any other adjustment

hereunder). Solely for purposes of this Section 9(y): (x) the terms “Potential

Adjustment Event,” “Merger Event,” and “Tender Offer” shall

each have the meanings assigned to each such term in the Equity Definitions (in the case

of the definition of “Potential Adjustment Event”, as amended by Section ‎9(j)(i),

and in the case of the definition of “Tender Offer”, as amended by the provisions

opposite the caption “Announcement Event” in Section 3) and (y) “Extraordinary

Dividend” means any cash dividend on the Shares other than a regular quarterly cash

dividend in an amount per Share that is less than or equal to the Regular Dividend.

(z) Counterparts. This Confirmation

Exhibit 10.2

Exchange Agreement

May __, 2026

Advanced Energy Industries, Inc.

2.50% Convertible

Senior Notes due 2028

The entity listed under “UNDERSIGNED”

on the signature page hereto (the “Undersigned” or the “Investor”), for itself and on behalf

of the beneficial owners listed on Exhibit A hereto (“Accounts”) for whom the Undersigned holds contractual

and investment authority (each, including the Undersigned if it is a party exchanging Notes (as defined below) hereunder, an “Exchanging

Investor”), hereby agrees to exchange with Advanced Energy Industries, Inc., a Delaware corporation (the “Company”),

certain of the Company’s 2.50% Convertible Senior Notes due 2028, CUSIP 007973 AE0 (the “Notes”) for the Aggregate

Exchange Consideration (as defined below) pursuant to this exchange agreement (this “Agreement”). The Investor acknowledges

and understands that the exchange (the “Exchange”) is being made without registration of the offer or sale of the Aggregate

Shares (as defined below) under the Securities Act of 1933, as amended (the “Securities Act”), or any securities laws

of any state of the United States or of any other jurisdiction pursuant to a private placement exemption from registration under Section 4(a)(2) of

the Securities Act and that each Exchanging Investor participating in the Exchange is required to be an institutional “accredited

investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is

also a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act. Capitalized terms used

but not defined in this Agreement have the respective meanings set forth in the indenture, dated as of September 12, 2023 (the “Indenture”),

between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”).

1.            On

the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set forth,

the Undersigned hereby agrees to exchange, and to cause each other Exchanging Investors, if any, to exchange, each $1,000 principal amount

of Notes (each an “Exchanged Note”) included in the aggregate principal amount of Notes set forth opposite its name

on Exhibit A hereto (collectively, the “Exchanged Notes”), free and clear of any Liens (as defined below)

(together with any documents of conveyance or transfer that the Company may deem necessary or desirable to transfer to and confirm in

the Company all right, title and interest in and to each Exchanged Notes free and clear of any Liens), in exchange for:

(a)            $[•]

interest on the Exchanged Notes as described below (the “Aggregate Cash”); and

(b)            [•]

shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”), (the “Aggregate

Shares” and, together with the Aggregate Cash, the “Aggregate Exchange Consideration”).

Upon Exchange, included in the Aggregate Exchange Consideration, the Undersigned will receive from the Company payment for any accrued

and unpaid interest on such Exchanged Notes to, but excluding, the Closing Date (as defined below).

Each of the Company, the Undersigned and each

Exchanging Investor agrees that no Exchanging Investor shall deliver a Conversion Notice with respect to any Exchanged Notes and each

Exchanging Investor shall hold the Exchanged Notes until the Closing (as defined below). In consideration for the performance of its obligations

hereunder (including as described in the immediately preceding sentence), the Company agrees to deliver the Aggregate Exchange Consideration

on the Closing Date to each Exchanging Investor in exchange for the applicable principal amount of Exchanged Notes as set forth on Exhibit A.

The Exchange shall occur in accordance with the

procedures set forth in Exhibit B hereto (the “Exchange Procedures”); provided that each of the

Company, the Undersigned and the Exchanging Investors acknowledge that the delivery of the Aggregate Shares to any Exchanging Investor

may be delayed due to procedures and mechanics within the system of Equiniti Trust Company LLC (the “Transfer Agent”),

The Depositary Trust Company (“DTC”) or The Nasdaq Stock Market LLC (“Nasdaq”) (including the procedures

and mechanics regarding the listing of the Aggregate Shares on Nasdaq) or other events beyond the Company’s control and that any

such a delay shall not be a default under this Agreement so long as (i) the Company is using its commercially reasonable efforts

to effect such delivery, or (ii) such delay arises due to a failure by an Exchanging Investor to deliver settlement instructions

or other information reasonably requested by the Company, the Transfer Agent, DTC, Nasdaq or any regulatory authority; provided,

further, that no delivery of the Aggregate Shares will be made until the Exchanged Notes have been properly submitted for exchange

in accordance with the Exchange Procedures and no interest will be payable by reason of any delay in making such delivery.

The closing of the Exchange (the “Closing”)

shall take place remotely via the exchange of documents and signatures at 10:00 a.m., New York City time, on May [•], 2026 (the

“Closing Date”), or at such other time and place as the Company and the Undersigned may mutually agree in writing.

All questions as to the form of all documents and the validity and acceptance of the Exchanged Notes and the Aggregate Exchange Consideration

will be determined by the Company, in its sole discretion, which determination shall be final and binding. Subject to the terms and conditions

of this Agreement, the Undersigned hereby, for itself and on behalf of the Exchanging Investors, effective as of the Closing, (a) waives

any and all other rights with respect to such Exchanged Notes other than the right to receive the Aggregate Exchange Consideration and

(b) releases and discharges the Company from any and all claims the undersigned and the Exchanging Investors may now have, or may

have in the future, arising out of, or related to, such Exchanged Notes.

the Company of the transactions contemplated hereby, except as may be required under any state or federal securities laws or that may

be obtained after the Closing without penalty or such that would not, individually or in the aggregate, reasonably be expected to have

Agreement has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding obligation of the

Company, enforceable against the Company in accordance with its terms, except that such enforcement may be subject to (a) bankruptcy,

insolvency, fraudulent transfer, reorganization, moratorium or other similar laws affecting or relating to enforcement of creditors’

rights generally and (b) general principles of equity, whether such enforceability is considered in a proceeding at law or in equity

certificate of incorporation, bylaws or other organizational documents of the Company, (b) any agreement or instrument to which the

Company is a party or by which the Company or any of its assets are bound, or (c) any laws, regulations or governmental or judicial

decrees, injunctions or orders applicable to the Company, except in the case of clauses (b) or (c), where such violations, conflicts,

breaches or defaults would not affect the Company’s ability to consummate the Exchange contemplated hereby.

(e)            When

delivered to the applicable Exchanging Investor pursuant to the Exchange in accordance with the terms of this Agreement, the Aggregate

Shares will (i) be validly issued, fully paid and non-assessable, (ii) be free and clear of any Liens (as defined in Section 3(c) below),

other agreements, and (iii) will not be subject to any preemptive, participation, rights of first refusal or other similar rights

(other than any such rights that will be waived prior to the Closing). Assuming the truth and accuracy of the representations and warranties

and compliance with the covenants of the Investor and each Exchanging Investor herein, the Aggregate Shares (A) will be issued in

the Exchange exempt from the registration requirements of the Securities Act pursuant to 4(a)(2) of the Securities Act, (B) will

the Closing, a notice for the listing of additional shares covering the Aggregate Shares shall have been submitted to Nasdaq, and the

Company has taken no action designed to, or likely to have the effect of, delisting the Common Stock from Nasdaq nor has the Company received

any notification that the Nasdaq is contemplating terminating such listing.

(g)            For

the twelve months prior to the date hereof, the Company has timely filed all reports required to be filed by it with the Securities and

Exchange Commission (the “SEC”) pursuant to the reporting requirements under Section 13 or 15(d) of the Securities

required interactive data file required to be submitted to the SEC.

(h)            At

or prior to 9:00 a.m., New York City time, on the first business day after the date hereof, the Company shall file with the Commission

a current report on Form 8-K announcing the Exchange, which current report the Company acknowledges and agrees will disclose all

confidential information (as described in the Wall Cross Email (defined in Section 3(y) below)) to the extent the Company

believes such confidential information constitutes material non-public information, if any, with respect to the Exchange or otherwise

communicated by the Company to the Investor in connection with the Exchange.

(i)            There

is no action, lawsuit, arbitration, claim or proceeding pending or, to the knowledge of the Company, threatened, against the Company that

would reasonably be expected to impede the consummation of the Exchange.

(j)            No

statement or printed material which is contrary to the publicly available filings and submissions made by the Company with the SEC under

the Exchange Act, or any other documents and agreements used in connection with the Exchange, has been made or given to the Investor by

Investor has all requisite corporate (or other applicable entity) power and authority to carry out and perform its obligations under the

terms hereof and the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Undersigned

(d)            The

law or any rule, regulation, judgment, decision, order or decree of any court or any governmental body or agency having jurisdiction over

the Undersigned or any of the Exchanging Investors.

(e)            The

Undersigned and each Exchanging Investor will comply with all applicable laws and regulations in effect necessary for each Exchanging

Investor to consummate the transactions contemplated hereby and obtain any consent, approval or permission required for the transactions

contemplated hereby and the laws and regulations of any jurisdiction to which the Undersigned and each such Exchanging Investor is subject,

and the Company shall have no responsibility therefor.

(f)            The

Undersigned and each Exchanging Investor acknowledges that (i) no person has been authorized to give any information or to make any

representation or warranty concerning the Company or the Exchange other than the information set forth herein in connection with the Undersigned’s

and each Exchanging Investor’s examination of the Company and the terms of the Exchange and the Aggregate Shares, and the Company

does not take, and Wells Fargo Securities, LLC (the “Advisor”) does not take, any responsibility for, and neither the

Company nor the Advisor can provide any assurance as to the reliability of, any other information that others may provide to the Undersigned

or any Exchanging Investor and (ii) the Advisor shall have no liability or obligation (including without limitation, for or with

respect to any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred

by it or any other person or entity), whether in contract, tort or otherwise, to the Undersigned or any Exchange Investor, as the case

may be, or to any person claiming through the Undersigned or an Exchange Investor, as the case may be, in respect of the Exchange.

(g)            The

Undersigned and each Exchanging Investor has such knowledge, skill and experience in business, financial and investment matters so that

it is capable of evaluating the merits and risks with respect to the Exchange and an investment in the Aggregate Shares. With the assistance

of each Exchanging Investor’s own professional advisors, to the extent that the Exchanging Investor has deemed appropriate, such

Exchanging Investor has made its own legal, tax, accounting and financial evaluation of the merits and risks of an investment in the Aggregate

Shares and the consequences of the Exchange and this Agreement and the Exchanging Investor has made its own independent decision that

the investment in the Aggregate Shares is suitable and appropriate for the Exchanging Investor. Each Exchanging Investor has considered

the suitability of the Aggregate Shares as an investment in light of such Exchanging Investor’s circumstances and financial condition

and is able to bear the risks associated with an investment in the Aggregate Shares.

(h)            The

Undersigned and each Exchanging Investor confirms that it and each Exchanging Investor is not relying on any communication (written or

oral) of the Company, the Advisor or any of their respective affiliates or representatives as investment advice or as a recommendation

to exchange its Notes and acquire the Aggregate Shares or the Aggregate Cash Amount in the Exchange. It is understood that information

provided by the Company, the Advisor or any of their respective affiliates and representatives shall not be considered investment advice

or a recommendation to participate in the Exchange, and that none of the Company, the Advisor or any of their respective affiliates or

representatives is acting or has acted as an advisor to the Undersigned or any Exchanging Investor in deciding to participate in the Exchange.

(i)            The

Undersigned and each Exchanging Investor confirms that neither the Company nor the Advisor has (i) given any guarantee, representation

or warranty as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise)

of an investment in the Aggregate Shares or (ii) made any representation or warranty to the Undersigned or any Exchanging Investor

regarding the legality of an investment in the Aggregate Shares under applicable legal investment or similar laws or regulations. In deciding

to participate in the Exchange, the Undersigned and each Exchanging Investor is not relying on the advice or recommendations of the Company

or the Advisor and the Undersigned and each Exchanging Investor has made its own independent decision that the investment in the Aggregate

Shares is suitable and appropriate for it.

(j)            The

Undersigned and each Exchanging Investor is familiar with the business and financial condition and operations of the Company and the Undersigned

and each Exchanging Investor has had the opportunity to conduct its own investigation of the Company and the Aggregate Shares. The Undersigned

and each Exchanging Investor has had access to the SEC filings of the Company and such other information concerning the Company and the

Aggregate Shares as it deems necessary to enable it to make an informed investment decision concerning the Exchange. The Undersigned and

each Exchanging Investor has been offered the opportunity to ask such questions of the Company and its representatives and received answers

thereto, as it deems necessary to enable it to make an informed investment decision concerning the Exchange.

(k)            The

Undersigned and each Exchanging Investor is an institutional “accredited investor” as defined in Rule 501(a)(1), (2),

(3) or (7) under the Securities Act and it and any account (including for purposes of this Section 3(k), the Accounts)

for which it is acting (for which it has sole investment discretion) is a “qualified institutional buyer” as defined in Rule 144A

under the Securities Act. The Undersigned and each Exchanging Investor agrees to furnish any additional information reasonably requested

by the Company or any of its affiliates to assure compliance with applicable U.S. federal and state securities laws in connection with

the Exchange.

(l)            The

Undersigned and each Exchanging Investor is not, and has not been during the consecutive three month period preceding the date hereof

and as of the Closing, will not be, a director, officer or “affiliate” within the meaning of Rule 144 promulgated under

the Securities Act (an “Affiliate”) of the Company. To its knowledge, the applicable Exchanging Investor did not acquire

any of the Exchanged Notes, directly or indirectly, from an Affiliate of the Company. Each Exchanging Investor beneficially owns and will

beneficially own as of the Closing Date (but without giving effect to the Exchange) (a) less than 5% of the outstanding Common Stock

of the Company (the “Units”) and (b) less than 5% of the aggregate number of votes that may be cast by holders

of those outstanding securities of the Company that entitle the holders thereof to vote generally on all matters submitted to the Company’s

stockholders for a vote. No Exchanging Investor is a subsidiary, Affiliate or, to its knowledge, otherwise closely-related to any director

or officer of the Company (each such director or officer, a “Related Party”). To its knowledge, no Related Party beneficially

owns 5% or more of the outstanding voting equity, or votes entitled to be cast by the outstanding voting equity, of the applicable Exchanging

Investor.

(m)            Neither

the Undersigned nor any Exchanging Investor is directly, or indirectly through one or more intermediaries, controlling or controlled by,

or under direct or indirect common control with, the Company.

(n)            Each

Exchanging Investor (including the Undersigned, if applicable) is acquiring the Aggregate Shares solely for its own beneficial account

(or for any account (including for purposes of this Section 3(n), the Accounts) for which it has sole investment discretion),

for investment purposes, and not with a view to, or for resale in connection with, any distribution of the Aggregate Shares in a manner

that would violate any securities laws. The Undersigned and each Exchanging Investor understands that the offer and sale of the Aggregate

Shares have not been registered under the Securities Act or any state securities laws and are being issued without registration under

the Securities Act by reason of specific exemption(s) under the provisions thereof which depend in part upon the investment intent

of the Exchanging Investors and the accuracy of the other representations and warranties made by the Undersigned and each Exchanging Investor

in this Agreement. The Undersigned and the Exchanging Investors understand that the Company and Advisor are each relying upon the representations,

warranties and agreements contained in this Agreement (and any supplemental information provided to the Company and Advisor by the Undersigned

or the Exchanging Investors) for the purpose of determining whether this transaction meets the requirements for such exemption(s) and

to issue the Aggregate Shares without legends as set forth herein.

(o)            The

Undersigned and each Exchanging Investor acknowledges and agrees that the terms of the Exchange have been mutually negotiated between

the Undersigned (on behalf of the Exchanging Investors) and the Company. The Undersigned and each Exchanging Investor was given a meaningful

opportunity to negotiate the terms of the Exchange.

(p)            The

Undersigned and each Exchanging Investor acknowledges and agrees that it had a sufficient amount of time to consider whether to participate

in the Exchange and that neither the Company nor the Advisor has placed any pressure on the Undersigned or any Exchanging Investor to

respond to the opportunity to participate in the Exchange. The Undersigned and each Exchanging Investor acknowledges and agrees that it

did not become aware of the Exchange through any form of general solicitation or advertising within the meaning of Rule 502(c) of

Regulation D under the Securities Act or otherwise through a “public offering” within the meaning of Section 4(a)(2) of

the Securities Act, nor did it receive any such general solicitation, advertising or public offering with respect to the Exchange, the

Notes, the Aggregate Shares or the Company.

(q)            No

broker, investment banker, finder or other person has been retained by or authorized to act on behalf of the Undersigned or any Exchanging

Investor in connection with the transactions contemplated hereby, and no commission or other remuneration has been paid or given directly

or indirectly by or on behalf of the Investor in connection therewith.

(r)            The

Undersigned will, upon request, execute and deliver, for itself and on behalf of any Exchanging Investor, any additional documents deemed

by the Company and the Trustee or the transfer agent to be reasonably necessary to complete the transactions contemplated by this Agreement.

(s)            No

later than one (1) business day after the date hereof, the Undersigned shall deliver in writing to the Company settlement instructions

substantially in the form of Exhibit B attached to this Agreement for each of the Exchanging Investors.

(t)            The

Undersigned and each Exchanging Investor acknowledges that the Company may issue appropriate stop-transfer instructions to its transfer

agent, if any, and may make appropriate notations to the same effect in its books and records to ensure compliance with the provisions

of this Section 3.

(u)            The

Undersigned and each Exchanging Investor acknowledges and agrees that the Advisor has not acted as a financial advisor or fiduciary to

the Undersigned or any Exchanging Investor and that the Advisor and its respective directors, officers, employees, representatives and

controlling persons have no responsibility for making, and have not made, any independent investigation of the information contained herein

or in the Company’s SEC filings and make no representation or warranty to the Undersigned or any Exchanging Investor, express or

implied, with respect to the Company, the Exchanged Notes or the Aggregate Shares or the accuracy, completeness or adequacy of the information

provided to the Undersigned or any Exchanging Investor (if any) or any other publicly available information, nor shall any of the foregoing

persons be liable for any loss or damages of any kind resulting from the use of the information contained therein or otherwise supplied

to the Undersigned or any Exchanging Investor.

(v)            By

entering into this Agreement, each Exchanging Investor (or Account(s) of such Exchanging Investor, if applicable) that delivers an

IRS Form W-8 (and applicable attachments) pursuant to Section 19 of this Agreement that does not properly establish an exemption

from U.S. federal withholding under the “interest” provision of a tax treaty with the United States hereby makes the representations

set forth in (A) Exhibit C-1, with respect to an Exchanging Investor (or Account(s) of such Exchanging Investor, if applicable)

that is not classified as a partnership for U.S. federal income tax purposes or (B) Exhibit C-2, with respect to an Exchanging

Investor (or Account(s) of such Exchanging Investor, if applicable) that is classified as a partnership for U.S. federal income tax

purposes. Notwithstanding the preceding sentence or Section 19 of this Agreement, the Company and its agents shall be entitled to

deduct and withhold from any consideration payable pursuant to this Agreement such amounts as may be required to be deducted or withheld

under applicable law, and shall be provided with a Form W-9 or the appropriate series of Form W-8 (and applicable attachments),

in order to establish whether any Exchanging Investor is entitled to an exemption from (or reduction in the rate of) withholding. To the

extent any such amounts are withheld and remitted to the appropriate taxing authority, such amounts shall be treated for all purposes

as having been paid to the Exchanging Investor to whom such amounts otherwise would have been paid.

(w)            The

Undersigned and each Exchanging Investor acknowledges and understands that no federal, state, local or foreign agency has passed upon

the merits or risks of an investment in the Aggregate Shares or made any finding or determination concerning the fairness or advisability

of this investment.

(x)            The

operations of the Undersigned and each Exchanging Investor have been conducted in material compliance with the applicable rules and

regulations administered or conducted by the U.S. Department of Treasury Office of Foreign Assets Control (“OFAC”),

the applicable rules and regulations of the Foreign Corrupt Practices Act (“FCPA”) and the applicable Anti-Money

Laundering (“AML”) rules in the Bank Secrecy Act. The Undersigned has performed due diligence necessary to reasonably

determine that each Exchanging Investor is not named on the lists of denied parties or blocked persons administered by OFAC, resident

in or organized under the laws of a country that is the subject of comprehensive economic sanctions and embargoes administered or conducted

by OFAC (“Sanctions”), are not otherwise the subject of Sanctions and have not been found to be in violation or under

suspicion of violating OFAC, FCPA or AML rules and regulations.

(y)            The

Undersigned and each Exchanging Investor acknowledges and agrees that it has not disclosed, and will not disclose, to any third party

any information regarding the Company or the Exchange, and that it has not transacted, and will not transact, in any securities of the

Company, including, but not limited to, any hedging transactions, from the time the Undersigned was first contacted by the Company or

the Advisor with respect to the Transactions until after the confidential information (as described in the confirmatory email received

by the Undersigned from the Advisor (the “Wall Cross Email”)) is made public.

(z)            If

the Undersigned is exchanging any Exchanged Notes and acquiring the Aggregate Shares as a fiduciary or agent for one or more accounts

(including for purposes of this Section ‎3(z), the Accounts which are Exchanging Investors), it represents that (i) it

has sole investment discretion with respect to each such account, (ii) it has full power to make the foregoing representations, warranties

and covenants on behalf of such account and (iii) it has contractual authority with respect to each such account.

(aa)      The

Undersigned and each Exchanging Investor understands and agrees that the Company, the Advisor and others will rely upon the truth and

accuracy of the foregoing representations, warranties and covenants and agrees that if any of the representations and warranties deemed

to have been made by it or the Exchanging Investors by their participation in the transactions contemplated by this Agreement and acquisition

of the Aggregate Shares are no longer accurate, the Undersigned and the applicable Exchanging Investor shall promptly notify the Company

and the Advisor. The Undersigned and each Exchanging Investor understands and agrees that, unless and except to the extent the Undersigned

or an Exchanging Investor notifies the Company in writing to the contrary before the Closing, each of the Undersigned’s and Exchanging

Investors’ representations and warranties contained in this Agreement will be deemed to have been reaffirmed and confirmed as of

the Closing.

Investor under this Agreement are subject to the satisfaction at or prior to the Closing of the following conditions precedent: (a) the
