Item 1.01

Entry into

a Material Definitive Agreement.

On

June 3, 2026, Celcuity Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”)

with Jefferies LLC, J.P. Morgan Securities LLC, TD Securities (USA) LLC and Guggenheim Securities, LLC, as representatives of the several

underwriters named therein (collectively, the “Underwriters”), agreeing, subject to customary conditions, to issue and sell

in a public offering $500,000,000 aggregate principal amount of the Company’s 0.250% Convertible Senior Notes due 2032 (the “Notes”)

to the Underwriters (the “Offering”). In addition, pursuant to the Underwriting Agreement, the Company granted the Underwriters

an option to purchase up to an additional $75,000,000 aggregate principal amount of the Notes, solely to cover over-allotments. On June

4, 2026, the Underwriters exercised such option to purchase an additional $75,000,000 aggregate principal amount of the Notes. The issuance

of $575,000,000 aggregate principal amount of the Notes was completed on June 8, 2026. The Notes were

issued pursuant to, and are governed by, an indenture (the “Base Indenture”), dated as of August 1, 2025, between

the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as supplemented by a second supplemental

indenture (the “Supplemental Indenture,” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”),

dated as of June 8, 2026, between the Company and the Trustee.

The

net proceeds from the Offering, after deducting underwriting discounts and commissions and offering expenses, were approximately $557.0

million, including the proceeds from the Underwriters’ exercise of their over-allotment option in full. The Company intends to

use the net proceeds from the Offering to repay in full all outstanding obligations under the Loan Agreement (defined below) and the

remainder for working capital and general corporate purposes, which may include clinical trial expenditures, commercial launch expenditures,

commercialization expenditures, research and development expenditures, capital expenditures, expansion of business development activities

and other general corporate purposes. The Company may also use a portion of the proceeds for the potential acquisition of businesses,

technologies, and products, although the Company has no current binding understandings, commitments, or agreements to do so.

The

Notes will be general, unsecured, senior obligations of the Company. The Notes will bear interest at a rate of 0.250% per annum, payable

semi-annually in arrears on February 1 and August 1 of each year, beginning on February 1, 2027. In addition, special interest will accrue

on the Notes upon the occurrence of certain events relating to the Company’s failure to file certain reports with the U.S. Securities

and Exchange Commission (the “SEC”) as provided in the Indenture. The Notes will mature on August 1, 2032, unless earlier

repurchased, redeemed or converted. The Notes will be convertible at the option of the holders if certain conditions are met and during

certain periods, at an initial conversion rate of 8.0302 shares of the Company’s common stock, par value $0.001 per share (the

“Common Stock”), per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately

$124.53 per share of Common Stock. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence

of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined

in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. The Company

will settle conversions of the Notes by paying or delivering, as applicable, cash, shares of Common Stock or a combination of cash and

shares of Common Stock, at the Company’s election, based on the applicable conversion rate.

The

Notes will be redeemable, in whole or in part (subject to certain limitations described below), at the Company’s option at any

time, and from time to time, on a redemption date on or after August 6, 2029 and on or before the 31st scheduled trading day immediately

before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid

interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of Common Stock exceeds

130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days

ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading

day immediately before the date the Company sends such notice. However, the Company may not redeem less than all of the outstanding Notes

unless at least $50.0 million aggregate principal amount of Notes are outstanding and not called for redemption as of the time the Company

sends the related redemption notice. In addition, calling any Note for redemption will constitute a Make-Whole Fundamental Change with

respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances

if it is converted after it is called for redemption.

If

certain events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, subject to certain exceptions

as provided in the Indenture, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal

amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase

date.

The

Notes will have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which

include the following: (i) certain payment defaults on the Notes (which, in the case of a default in the payment of interest on the Notes,

will be subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified

periods of time; (iii) the Company’s failure to convert a Note in accordance with the Indenture within a specified period of time;

(iv) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate

with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially

all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (v) a default by the Company in its other

obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given

in accordance with the Indenture; (vi) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness

for borrowed money of at least $60,000,000; (vii) certain events of bankruptcy, insolvency and reorganization involving the Company or

any of its significant subsidiaries; and (viii) certain judgments being rendered against the Company or any of its significant subsidiaries

for the payment of at least $60,000,000.

If

an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect

to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest, if any, on,

all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any

other Event of Default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate

principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued

and unpaid interest, if any, on, all of the Notes then outstanding to become due and payable immediately. Notwithstanding the foregoing,

the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply

with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on

the Notes for up to 365 days, at a rate per annum equal to 0.25% of the principal amount of the Notes for the first 180 days on which

special interest accrues and, thereafter, at a rate per annum equal to 0.50% of the principal amount thereof.

The

above description of the Underwriting Agreement, the Indenture and the Notes is a summary and is not complete. The Underwriting Agreement

contains customary representations, warranties, covenants and indemnification obligations of the Company and the Underwriters, including

for liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and other obligations of the parties.

The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and

as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by such

parties. A copy of the Underwriting Agreement, the Base Indenture, the Supplemental Indenture and the form of the certificate representing

the Notes are filed as Exhibits 1.1, 4.1, 4.2 and 4.3, respectively, to this Current Report on Form 8-K, and the above summary is qualified

in its entirety by reference to the terms of the Underwriting Agreement, the Base Indenture, the Supplemental Indenture and the Notes

set forth in such exhibits.

The

Offering is being made pursuant to a prospectus supplement, dated June 3, 2026, filed with the SEC on June 5, 2026 and an accompanying

base prospectus that forms a part of the Registration Statement. This Current Report on Form 8-K does not constitute an offer to sell

or a solicitation of an offer to buy any of the Notes.

Item 1.02

Termination

of a Material Definitive Agreement

On

June 8, 2026, the Company completed a voluntary prepayment of all outstanding principal, accrued and unpaid interest, fees, costs and

expenses, equal to approximately $[137.5 million] in the aggregate (the “Payoff Amount”), under that certain Amended and

Restated Loan and Security Agreement, dated as of May 30, 2024, by and among the Company, as borrower, Oxford Finance LLC, a Delaware

limited liability company (“Oxford”), as collateral agent and a lender, Innovatus Life Sciences Lending Fund I, LP, a Delaware

limited partnership (“Innovatus” and together with Oxford, the “Lenders”), as a lender, and the other lenders

party thereto (as amended, restated, supplemented or otherwise modified prior to the date hereof, the “Loan Agreement”).

Upon receipt by the Lenders of the Payoff Amount on June 8, 2026, all obligations, covenants, debts and liabilities of the Company under

the Loan Agreement were satisfied and discharged in full, and the Loan Agreement and all other documents entered into in connection with

the Loan Agreement were terminated.

The

Loan Agreement provided for term loans with aggregate maximum commitments of up to $350 million (the “Term Loans”), with

the potential for an additional $150 million in discretionary term loans at the Lenders’ sole discretion. Under the Loan Agreement,

the Company had total borrowings of $100 million as of May 30, 2024, and on September 9, 2025, the Company borrowed an additional $30

million. The Term Loans bore interest at a floating per annum rate equal to the greater of (i) the Prime Rate (as defined in the Loan

Agreement) and (ii) 7.75%, plus 2.85% (the “Basic Rate”). Additionally, 1.00% of the Basic Rate was payable in kind by adding

such amount to the outstanding principal balance on a monthly basis through May 31, 2027. Interest-only payments on the borrowings under

the Loan Agreement were due through May 31, 2027. Interest-only payments on the borrowings under the Loan Agreement were due through

August 1, 2028, or if certain regulatory milestones were met, through March 1, 2029. After the interest-only payment period, borrowings

under the Loan Agreement were due in equal monthly payments of principal and accrued interest until the maturity date of November 1,

2029.

Ladies and Gentlemen:

Introductory.

Celcuity Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named

in Schedule A (the “Underwriters”) $500,000,000 principal amount of 0.250% Convertible Senior Notes due 2032

of the Company (the “Securities”). The $500,000,000 principal amount of Securities to be sold by the Company are called

the “Firm Securities.” In addition, the Company has granted to the Underwriters an option to purchase up to an additional

$75,000,000 principal amount of Securities as provided in Section 2. The additional $75,000,000 principal amount of Securities to be

sold by the Company pursuant to such option are collectively called the “Optional Securities.” The Firm Securities

and, if and to the extent such option is exercised, the Optional Securities are collectively called the “Offered Securities.”

Jefferies LLC (“Jefferies”), J.P. Morgan Securities LLC (“J.P. Morgan”), TD Securities (USA) LLC

(“TD Cowen”) and Guggenheim Securities, LLC (“Guggenheim Securities”) have agreed to act as representatives

of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of

the Offered Securities. The Offered Securities will be convertible into cash, shares (the “Underlying Securities”)

of common stock of the Company, par value $0.001 per share (the “Common Stock”), or a combination of cash and Underlying

Securities, at the Company’s election. The Securities will be issued pursuant to an indenture (the “Base Indenture”),

dated as of August 1, 2025, as supplemented by a supplemental indenture (the Base Indenture, as so supplemented, the “Indenture”),

to be dated as of the First Closing Date (as hereinafter defined), between the Company and U.S. Bank Trust Company, National Association,

as trustee (the “Trustee”). To the extent there are no additional underwriters listed on Schedule A, the term

“Representatives” as used herein shall mean you, as Underwriters, and the term “Underwriters” shall mean either

The

with the public offering and sale of the Offered Securities. Such registration statement, as amended, including the financial statements,

exhibits and schedules thereto, in the form in which it became effective under the Securities Act of 1933, as amended, and the rules

and regulations promulgated thereunder (collectively, the “Securities Act”), including all documents incorporated

or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the time of effectiveness pursuant

to Rule 430B under the Securities Act, is called the “Registration Statement.” The preliminary prospectus supplement

dated June 3, 2026 describing the Offered Securities and the offering thereof (the “Preliminary Prospectus Supplement”),

together with the Base Prospectus, is called the “Preliminary Prospectus,” and the Preliminary Prospectus and any

other prospectus supplement to the Base Prospectus in preliminary form that describes the Offered Securities and the offering thereof

and is used prior to the filing of the Prospectus (as defined below), together with the Base Prospectus, is called a “preliminary

prospectus.” As used herein, the term “Prospectus” shall mean the final prospectus supplement to the Base

Prospectus that describes the Offered Securities and the offering thereof (the “Final Prospectus Supplement”), together

with the Base Prospectus, in the form first used by the Underwriters to confirm sales of the Offered Securities or in the form first

made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act. References

herein to the Preliminary Prospectus, any preliminary prospectus and the Prospectus shall refer to both the prospectus supplement and

the Base Prospectus components of such prospectus. As used herein, “Applicable Time” is 5:45 p.m. (New York City time)

on June 3, 2026. As used herein, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities

Act, and “Time of Sale Prospectus” means the Preliminary Prospectus, as amended or supplemented immediately prior

to the Applicable Time, together with the free writing prospectuses, if any, identified in Schedule B hereto and the pricing term

sheet set forth on Schedule C hereto. As used herein, “Road Show” means a “road show” (as defined

in Rule 433 under the Securities Act) relating to the offering of the Offered Securities contemplated hereby that is a “written

communication” (as defined in Rule 405 under the Securities Act). As used herein, “Section 5(d) Written Communication”

means each written communication (within the meaning of Rule 405 under the Securities Act) that is made in reliance on Section 5(d) of

the Securities Act by the Company or any person authorized to act on behalf of the Company to one or more potential investors that are

qualified institutional buyers (“QIBs”) and/or institutions that are accredited investors (“IAIs”),

as such terms are respectively defined in Rule 144A and Rule 501(a) under the Securities Act, to determine whether such investors might

have an interest in the offering of the Offered Securities; “Section 5(d) Oral Communication” means each oral communication,

if any, made in reliance on Section 5(d) of the Securities Act by the Company or any person authorized to act on behalf of the Company

made to one or more QIBs and/or one or more IAIs to determine whether such investors might have an interest in the offering of the Offered

Securities; “Marketing Materials” means any materials or information provided to investors by, or with the approval

of, the Company in connection with the marketing of the offering of the Offered Securities, including any roadshow or investor presentations

made to investors by the Company (whether in person or electronically); and “Permitted Section 5(d) Communication”

means the Section 5(d) Written Communication(s) and Marketing Materials listed on Schedule C attached hereto.

“Exchange Act”) that is or is deemed to be incorporated by reference in the Registration Statement, the Preliminary

The

Company hereby confirms its agreements with the Underwriters as follows:

Section

1. Representations and Warranties of the Company. The Company hereby represents, warrants and covenants to each Underwriter, as of

the date of this Agreement, as of the First Closing Date (as hereinafter defined) and as of each Option Closing Date (as hereinafter

defined), if any, as follows:

(a)

Compliance with Registration Requirements. The Registration Statement has become effective under the Securities Act. The Company

has complied, to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information,

if any. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have

been instituted or are pending or, to the knowledge of the Company, are contemplated or threatened by the Commission. At the time the

Company’s Annual Report on Form 10-K for the year ended December 31, 2025 was filed with the Commission, or, if later, at the time

the Registration Statement was originally filed with the Commission, as well as at the time the Company or any person acting on its behalf

(within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made any offer relating to the Offered Securities

in reliance on the exemption contained in Rule 163 under the Securities Act, the Company was a “well-known seasoned issuer”

as defined in Rule 405 under the Securities Act, and as of the date hereof, the Company met or meets the then-applicable requirements

for use of Form S-3 under the Securities Act. The Registration Statement is an “automatic shelf registration statement,”

as defined in Rule 405 under the Securities Act, and became effective on January 9, 2026. The Company has not received from the Commission

any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the Company’s use of the automatic shelf registration

form. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Time of Sale Prospectus

and the Prospectus, at the time they were or hereafter are filed with the Commission, or became effective under the Exchange Act, as

the case may be, complied and will comply in all material respects with the requirements of the Exchange Act. As of the date of this

Agreement, the Company is an “experienced issuer” as defined in FINRA Rule 5110(j)(6).

3

(b)

Disclosure. Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities

Act and, if filed by electronic transmission pursuant to EDGAR, was identical (except as may be permitted by Regulation S-T under the

Each of the Registration Statement and any post-effective amendment thereto, at the time it became or becomes effective, complied and

will comply in all material respects with the Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations

of the Commission thereunder (collectively, the “Trust Indenture Act”), and did not and will not contain any untrue

statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein

not misleading. As of the Applicable Time, the Time of Sale Prospectus did not, and at the First Closing Date (as defined in Section

2) and at each applicable Option Closing Date (as defined in Section 2), will not, contain any untrue statement of a material fact or

omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were

made, not misleading. The Prospectus, as of its date, did not, and at the First Closing Date and at each applicable Option Closing Date,

will not, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements

a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not

misleading.

(assuming the maximum increase to such conversion rate for a conversion of Offered Securities in connection with a “make-whole

fundamental change” or a redemption of the Offered Securities) (the “Maximum Number of Underlying Securities”)

have been duly authorized and reserved for issuance by the Company by all necessary corporate action and such Maximum Number of Underlying

Securities, if and when issued upon any conversion of the Offered Securities in accordance with the terms of the Offered Securities and

the Indenture, will be validly issued, fully paid and non-assessable; no holder of such Underlying Securities will be subject to personal

with generally accepted accounting principles as applied in the United States and to maintain accountability for assets; (iii) access

and its principal financial officer by others within the Company, particularly during the periods in which the periodic reports required

under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company for effectiveness as of the end of the

Company’s most recent fiscal quarter; and (iii) are effective in all material respects to perform the functions for which they

internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s

internal control over financial reporting. The Company is not aware of any change in its internal control over financial reporting that

internal control over financial reporting.

in good standing under the laws of the State of Delaware and has the corporate power and authority to own, lease and operate its properties

and to conduct its business as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus and to enter into

and perform its obligations under each of the Transaction Documents. The Company is duly qualified as a foreign corporation to transact

business and is in good standing in the State of Minnesota and is duly qualified in each other jurisdiction in which such qualification

is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to be so

qualified would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Change.

(r)

Subsidiaries. The Company does not own or control, directly or indirectly, any corporation, association or other entity.

(s)

Capitalization and Other Capital Stock Matters. The authorized, issued and outstanding capital stock of the Company is as

pursuant to employee benefit plans, or upon the exercise or conversion of outstanding options, warrants or convertible securities, in

each case described in the Registration Statement, the Time of Sale Prospectus and the Prospectus). The Offered Securities conform in

refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any capital stock

or other equity interest in the Company other than those described in the Registration Statement, the Time of Sale Prospectus and the

Prospectus. The descriptions of the Company’s stock option, stock bonus and other stock plans or any other arrangements, and the

shares of Common Stock are listed on The Nasdaq Capital Market (the “Nasdaq”), and the Company has taken no action

designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the

shares of Common Stock from the Nasdaq, nor has the Company received any notification that the Commission or the Nasdaq is contemplating

terminating such registration or listing. The Company is in compliance with all applicable listing requirements of Nasdaq.

(u)

Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. The Company is not in violation

of its charter or by-laws nor is it in default (or, with the giving of notice or lapse of time, would be in default) (“Default”)

under any indenture, loan, credit agreement, note, lease, license agreement, contract, franchise or other instrument (including, without

limitation, any pledge agreement, security agreement, mortgage or other instrument or agreement evidencing, guaranteeing, securing or

relating to indebtedness) to which the Company is a party or by which it may be bound, or to which its properties or assets are subject

(each, an “Existing Instrument”), except for such Defaults as would not be expected, individually or in the aggregate,

to result in a Material Adverse Change. The Company’s execution, delivery and performance of each of the Transaction Documents,

consummation of the transactions contemplated thereby and by the Registration Statement, the Time of Sale Prospectus and the Prospectus

and the issuance and sale of the Offered Securities, including the issuance and delivery of any Common Stock and the payment of any cash,

in each case, due upon conversion thereof (including the use of proceeds from the sale of the Offered Securities as described in the

Registration Statement, the Time of Sale Prospectus and the Prospectus under the caption “Use of Proceeds”) (i) have been

duly authorized by all necessary corporate action and will not result in any violation of the provisions of the charter or by-laws of

the Company, (ii) will not conflict with or constitute a breach of, or Default or a Debt Repayment Triggering Event (as defined below)

under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant

to, or require the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any law, administrative

regulation or administrative or court decree applicable to the Company. No consent, approval, authorization or other order of, or registration

or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s execution, delivery

and performance of each of the Transaction Documents and consummation of the transactions contemplated thereby and by the Registration

Statement, the Time of Sale Prospectus and the Prospectus, except such as have been obtained or made by the Company and are in full force

and effect, under the Securities Act, including, but not limited to, the registration of the Offered Securities, the qualification of

the Indenture under the Trust Indenture Act and such as may be required under applicable state securities or blue sky laws or the Financial

Industry Regulatory Authority, Inc. (“FINRA”). As used herein, a “Debt Repayment Triggering Event”

means any event or condition which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture

or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption

or repayment of all or a portion of such indebtedness by the Company.

8

(v)

Compliance with Laws. The Company has been and is in compliance with all applicable laws, rules and regulations, except where

failure to be so in compliance would not be expected, individually or in the aggregate, to result in a Material Adverse Change.

(w)

No Material Actions or Proceedings. There is no action, suit, proceeding, inquiry or investigation brought by or before any

legal or governmental entity now pending or, to the knowledge of the Company, threatened, against or affecting the Company, which would

be expected, individually or in the aggregate, to result in a Material Adverse Change. No material labor dispute with the employees of

the Company, or with the employees of any principal supplier, manufacturer, customer or contractor of the Company, exists or, to the

knowledge of the Company, is threatened or imminent.

(x)

Intellectual Property Rights. The Company owns, or has obtained valid and enforceable licenses for, the inventions, patent

applications, patents, trademarks, trade names, service names, copyrights, trade secrets and other intellectual property described in

the Registration Statement, the Time of Sale Prospectus and the Prospectus as being owned or licensed by it or which are necessary for

the conduct of its businesses as currently conducted or as currently proposed to be conducted (collectively, “Intellectual Property”),

and the conduct of its businesses does not and, to the Company’s knowledge, will not, infringe, misappropriate or otherwise conflict

in any material respect with any such rights of others. The Intellectual Property of the Company has not been adjudged by a court of

competent jurisdiction to be invalid or unenforceable, in whole or in part, and the Company is unaware of any facts which would form

a reasonable basis for any such adjudication. To the Company’s knowledge: (i) there are no third parties who have rights to any

Intellectual Property, except for customary reversionary rights of third-party licensors with respect to Intellectual Property that is

disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus as licensed to the Company; and (ii) there is

no infringement by third parties of any Intellectual Property. There is no pending or, to the Company’s knowledge, threatened action,

suit, proceeding or claim by others: (A) challenging the Company’s rights in or to any Intellectual Property, and the Company is

unaware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim; (B) challenging the validity,

enforceability or scope of any Intellectual Property, and the Company is unaware of any facts which would form a reasonable basis for

any such action, suit, proceeding or claim; or (C) asserting that the Company infringes or otherwise violates, or would, upon the commercialization

of any product or service described in the Registration Statement, the Time of Sale Prospectus or the Prospectus as under development,

infringe or violate, any patent, trademark, trade name, service name, copyright, trade secret or other proprietary rights of others,

and the Company is unaware of any facts which would form a reasonable basis for any such action, suit, proceeding or claim. The Company

has complied with the terms of each agreement pursuant to which Intellectual Property has been licensed to the Company, and all such

agreements are in full force and effect. To the Company’s knowledge, there are no material defects in any of the patents or patent

applications included in the Intellectual Property. The Company has taken all reasonable steps to protect, maintain and safeguard its

Intellectual Property, including the execution of appropriate nondisclosure, confidentiality agreements and invention assignment agreements

and invention assignments with their employees, and no employee of the Company is in or has been in violation of any term of any employment

contract, patent disclosure agreement, invention assignment agreement, non-competition agreement, non-solicitation agreement, nondisclosure

agreement, or any restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s

employment with the Company. The duty of candor and good faith as required by the United States Patent and Trademark Office during the

prosecution of the United States patents and patent applications included in the Intellectual Property have been complied with; and in

all foreign offices having similar requirements, all such requirements have been complied with. None of the Company owned Intellectual

Property or technology (including information technology and outsourced arrangements) employed by the Company has been obtained or is

being used by the Company in violation of any contractual obligation binding on the Company or any of its officers, directors or employees

or otherwise in violation of the rights of any persons. The product candidates described in the Registration Statement, the Time of Sale

Prospectus and the Prospectus as under development by the Company fall within the scope of the claims of one or more patents owned by,

or exclusively licensed to, the Company.

9

(y)

All Necessary Permits, etc. The Company possesses such valid and current certificates, authorizations or permits required

by state, federal or foreign regulatory agencies or bodies to conduct its businesses as currently conducted and as described in the Registration

Statement, the Time of Sale Prospectus or the Prospectus (“Permits”), except where the failure to so possess or comply

would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. The Company is not in violation

of, or in default under, any of the Permits nor has it received any notice of proceedings relating to the revocation or modification

of, or non-compliance with, any such certificate, authorization or permit, except where such violation, default, revocation, modification

or non-compliance would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change.

(z)

Title to Properties. The Company has good and marketable title to all of the real and personal property and other assets reflected

as owned in the financial statements referred to in Section 1(n) above (or elsewhere in the Registration Statement, the Time of Sale

Prospectus or the Prospectus), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, adverse

claims and other defects, other than those described in the Registration Statement, the Time of Sale Prospectus or the Prospectus. The

real property, improvements, equipment and personal property held under lease by the Company are held under valid and enforceable leases,

with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property,

improvements, equipment or personal property by the Company.

(aa)

Tax Law Compliance. The Company has (i) filed all tax returns required to be filed by it (or has properly requested extensions

thereof) and (ii) has paid all taxes required to be paid by it and, if due and payable, any related or similar assessment, fine or penalty

levied against it, except as may be being contested in good faith and by appropriate proceedings, except, in each case, where a failure

to file such tax returns or pay such taxes or amounts would not, individually or in the aggregate, reasonably be expected to have a Material

Adverse Change. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in Section

1(n) above in respect of all federal, state and foreign income and franchise taxes for all periods ending on or prior to the dates indicated

therein.

(bb)

Insurance. The Company is insured by recognized, financially sound and reputable institutions with policies in such amounts

and with such deductibles and covering such risks as are generally deemed adequate and customary for its business including, but not

limited to, policies covering real and personal property owned or leased by the Company against theft, damage, destruction, acts of vandalism

and earthquakes and policies covering the Company for product liability claims and clinical trial liability claims. The Company has no

reason to believe that it will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain

comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost

that would not be expected to result in a Material Adverse Change. The Company has not been denied any insurance coverage which it has

sought or for which it has applied, except as would not be expected to result, individually or in the aggregate, in a Material Adverse

Change.

10

(cc)

Compliance with Environmental Laws. Except as would not be expected, individually or in the aggregate, to result in a Material

Adverse Change: (i) the Company is not in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance,

code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative

order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation,

ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations

relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances,

petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution,

use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”);

(ii) the Company has all permits, authorizations and approvals required under any applicable Environmental Laws and is in compliance

with their requirements; (iii) there are no pending or, to the knowledge of the Company, threatened administrative, regulatory or judicial

actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating

to any Environmental Law against the Company; and (iv) there are no events or circumstances that might reasonably be expected to form

the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency,

against or affecting the Company relating to Hazardous Materials or any Environmental Laws.

(dd)

ERISA Compliance. The Company and any “employee benefit plan” (as defined under the Employee Retirement Income

Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”))

established or maintained by the Company or its “ERISA Affiliates” (as defined below) are in compliance in all material respects

with ERISA. “ERISA Affiliate” means, with respect to the Company, any member of any group of organizations described

in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations

thereunder (the “Code”) of which the Company is a member. No “reportable event” (as defined under ERISA)

has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by

the Company or any of its ERISA Affiliates. No “employee benefit plan” established or maintained by the Company or any of

its ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities”

(as defined under ERISA). Neither the Company nor any of its ERISA Affiliates has incurred or reasonably expects to incur any liability

under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections

412, 4971, 4975 or 4980B of the Code. Each employee benefit plan established or maintained by the Company or any of its ERISA Affiliates

that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure

to act, which would cause the loss of such qualification.

(ee)

Company Not an “Investment Company.” The Company is not, and will not be, either after receipt of payment for

the Offered Securities or after the application of the proceeds therefrom as described under “Use of Proceeds” in the Registration

Statement, the Time of Sale Prospectus or the Prospectus, required to register as an “investment company” under the Investment

Company Act of 1940, as amended (the “Investment Company Act”).

11

(ff)

No Price Stabilization or Manipulation; Compliance with Regulation M. The Company has not taken, directly or indirectly, any

action designed to or that might cause or result in stabilization or manipulation of the price of the Offered Securities or of any “reference

security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation M”)) with respect to the

Offered Securities, whether to facilitate the sale or resale of the Offered Securities or otherwise, and has not taken any action which

would directly or indirectly violate Regulation M.

(gg)

Related-Party Transactions. There are no business relationships or related-party transactions involving the Company or any

other person required to be described in the Registration Statement, the Time of Sale Prospectus or the Prospectus that have not been

described as required.

(hh)

FINRA Matters. All of the information provided to the Underwriters or to counsel for the Underwriters by the Company, its

counsel, its officers and directors and the holders of any securities (debt or equity) or options to acquire any securities of the Company

in connection with the offering of the Offered Securities is true, complete, correct and compliant with FINRA’s rules and any letters,

to a purchaser, not misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law. Neither the Representatives’

consent to, nor delivery of, any such amendment or supplement shall constitute a waiver of any of the Company’s obligations under

Section 3(b) or Section 3(c).

Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register

the Offered Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian

provincial securities laws (or other foreign laws) of those jurisdictions designated by the Representatives, shall comply with such laws

and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered

Securities. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general

service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation where it is

not otherwise subject to taxation. The Company will advise the Representatives promptly of the suspension of the qualification or registration

of (or any such exemption relating to) the Offered Securities for offering, sale or trading in any jurisdiction or any initiation or

Act and the rules and regulations of the Commission thereunder, provided that the Company will be deemed to have made generally available

such statement to the extent it is available on EDGAR.

(l)

Continued Compliance with Securities Laws. The Company will comply with the Securities Act and the Exchange Act so as to permit

the completion of the distribution of the Offered Securities as contemplated by the Transaction Documents, the Registration Statement,

the Time of Sale Prospectus, and the Prospectus. Without limiting the generality of the foregoing, the Company will, during the period

when a prospectus relating to the Offered Securities is required by the Securities Act to be delivered (whether physically or through

compliance with Rule 172 under the Securities Act or any similar rule), file on a timely basis with the Commission and the Nasdaq all

reports and documents required to be filed under the Exchange Act.

(m)

The Maximum Number of Underlying Securities. The Company will reserve and keep available at all times, free of preemptive

rights, a number of shares of Common Stock equal to the Maximum Number of Underlying Securities. The Company will use its reasonable

best efforts to effect and maintain the listing of a number of shares of Common Stock issuable upon conversion of the Offered Securities

that will allow investors to store and have continuously ready access to the Prospectus at any future time, without charge to investors

(other than any fee charged for subscription to the Internet as a whole and for on-line time). The Company hereby confirms that it has

included or will include in the Prospectus filed pursuant to EDGAR or otherwise with the Commission and in the Registration Statement

at the time it was declared effective an undertaking that, upon receipt of a request by an investor or his or her representative, the

or similar transaction affecting the outstanding shares of Common Stock; or (ix) publicly announce the intention to do any of the foregoing;

provided, however, that the Company may (A) effect the transactions contemplated the Transaction Documents, (B) issue and sell

acquire other securities or rights ultimately exchangeable or exercisable for, or convertible into, shares of Common Stock.

Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of

notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying

party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission to so notify the indemnifying

party will not relieve the indemnifying party from any liability which it may have to any indemnified party to the extent the indemnifying

party is not materially prejudiced as a proximate result of such failure and shall not in any event relieve the indemnifying party from

any liability that it may have otherwise than on account of this indemnity agreement. In case any such action is brought against any

indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will

be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified,

by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume

the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, that if the defendants

in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded

that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any

such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional

to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume

such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt

of notice from the indemnifying party to such indemnified party of such indemnifying party’s election to so assume the defense

of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party

under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof

unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being

understood, however, that the indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (together

with local counsel), representing the indemnified parties who are parties to such action), which counsel (together with any local counsel)

for the indemnified parties shall be selected by Jefferies, J.P. Morgan, TD Cowen and Guggenheim Securities (in the case of counsel for

the indemnified parties referred to in Section 9(a) above) or by the Company (in the case of counsel for the indemnified parties referred

to in Section 9(b) above) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent

the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized

in writing the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees

and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred.

28

(d)

Settlements. The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected

without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party

agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment.

Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the

indemnified party for fees and expenses of counsel as contemplated by Section 9(c), the indemnifying party shall be liable for any settlement

of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such

indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance

with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified

party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding

in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such

indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all

liability on claims that are the subject matter of such action, suit or proceeding and does not include an admission of fault or culpability

or a failure to act by or on behalf of such indemnified party.

Section

10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to or otherwise insufficient

to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each

indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any

losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative

benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Offered Securities

pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion

as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company,

on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses,

claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the

Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Offered Securities pursuant

to this Agreement shall be deemed to be in the same respective proportions as the total proceeds from the offering of the Offered Securities

pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discounts and commissions

received by the Underwriters, in each case as set forth on the front cover page of the Prospectus, bear to the aggregate initial public

offering price of the Offered Securities as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters,

on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a

material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand,

or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct

or prevent such statement or omission.

The

amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed

to include, subject to the limitations set forth in Section 9(c), any legal or other fees or expenses reasonably incurred by such party

in connection with investigating or defending any action or claim. The provisions set forth in Section 9(c) with respect to notice of

commencement of any action shall apply if a claim for contribution is to be made under this Section 10; provided, however, that

no additional notice shall be required with respect to any action for which notice has been given under Section 9(c) for purposes of

indemnification.

29

The

Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined

by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which

does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding

the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts

and commissions received by such Underwriter in connection with the Offered Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution

from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to

this Section 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective

names on Schedule A. For purposes of this Section 10, each affiliate, director, officer, employee and agent of an Underwriter

and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange Act shall have the same

rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration

Statement, and each person, if any, who controls the Company within the meaning of the Securities Act and the Exchange Act shall have

the same rights to contribution as the Company.

Section

11. Default of One or More of the Several Underwriters. If, on the First Closing Date or any Option Closing Date any one or

more of the several Underwriters shall fail or refuse to purchase Offered Securities that it or they have agreed to purchase hereunder

on such date, and the aggregate principal amount of Offered Securities which such defaulting Underwriter or Underwriters agreed but failed

or refused to purchase does not exceed 10% of the aggregate principal amount of the Offered Securities to be purchased on such date,

the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including

any of the Underwriters, but if no such arrangements are made by such date, the other Underwriters shall be obligated, severally and

not jointly, in the proportions of the principal amount of Firm Securities set forth opposite their respective names on Schedule A

bears to the aggregate principal amount of Firm Securities set forth opposite the names of all such non-defaulting Underwriters, or in

such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the

Offered Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the

First Closing Date or any Option Closing Date any one or more of the Underwriters shall fail or refuse to purchase Offered Securities

and the aggregate principal amount of Offered Securities with respect to which such default occurs exceeds 10% of the aggregate principal

amount of Offered Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the

purchase of such Offered Securities are not made within 48 hours after such default, this Agreement shall terminate without liability

of any party to any other party except that the provisions of Section 4, Section 7, Section 9 and Section 10 shall at all times be effective

and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the First

Closing Date or the applicable Option Closing Date, as the case may be, but in no event for longer than seven days in order that the

required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As

used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting

Underwriter under this Section 11. Any action taken under this Section 11 shall not relieve any defaulting Underwriter from liability

in respect of any default of such Underwriter under this Agreement.

30

Section

12. Termination of this Agreement. Prior to the purchase of the Firm Securities by the Underwriters on the First Closing Date,

this Agreement may be terminated by the Representatives by notice given to the Company if at any time: (i) trading or quotation in any

of the Company’s securities shall have been suspended or limited by the Commission or by the Nasdaq, or trading in securities generally

on either the Nasdaq or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established

on any of such stock exchanges; (ii) a general banking moratorium shall have been declared by any federal or New York authorities or

a material disruption in commercial banking or securities settlement or clearance services in the United States; (iii) there shall have

occurred any outbreak or escalation of national or international hostilities or the declaration of the United States of a national emergency

or war, or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or

development involving a prospective substantial change in United States’ or international political, financial or economic conditions,

as in the judgment of the Representatives is material and adverse and makes it impracticable to market the Offered Securities in the

manner and on the terms described in the Time of Sale Prospectus or the Prospectus or to enforce contracts for the sale of securities;

(iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) the Company shall have sustained

a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may

interfere materially with the conduct of the business and operations of the Company regardless of whether or not such loss shall have

been insured. Any termination pursuant to this Section 12 shall be without liability on the part of (a) the Company to any Underwriter,

except that the Company shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Section

4 or Section 7 hereof or (b) any Underwriter to the Company; provided, however, that the provisions of Section 9 and Section 10

shall at all times be effective and shall survive such termination.

Section

13. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Offered Securities

pursuant to this Agreement, including the determination of the public offering price of the Offered Securities and any related discounts

and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters,

on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter

is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees

or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with

respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is

currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated

hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged

in a broad range of transactions that involve interests that differ from those of the Company, and (e) the Underwriters have not provided

any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own

legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

Section

14. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties

and other statements of the Company, of its officers and of the several Underwriters set forth in or made pursuant to this Agreement

will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of

its or their partners, officers or directors or any controlling person, as the case may be, and, anything herein to the contrary notwithstanding,

will survive delivery of and payment for the Offered Securities sold hereunder and any termination of this Agreement.

Underwriters pursuant to Section 11 hereof, and to the benefit of the affiliates, directors, officers, employees, agents and controlling

persons referred to in Section 9 and Section 10, and in each case their respective successors and personal representatives, and no other

Section

18. Recognition of the U.S. Special Resolution Regimes.

(a)

In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the

transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the

same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and

obligation, were governed by the laws of the United States or a state of the United States.

(b)

In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding

under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted

to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement

were governed by the laws of the United States or a state of the United States.

For

purposes of this Agreement, (A) “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in,

and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); (B) “Covered Entity” means any of the following:

(i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a

“covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered

FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); (C) “Default Right”

has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1,

as applicable; and (D) “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the

regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations

promulgated thereunder.

Section

19. Waiver of Trial by Jury. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders

and affiliates) and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all

right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section

20. Governing Law Provisions. This Agreement shall be governed by and construed in accordance with the internal laws of the

State of New York applicable to agreements made and to be performed in such state. Any legal suit, action or proceeding arising out of

or based upon this Agreement or the transactions contemplated hereby may be instituted in the federal courts of the United States of

America located in the Borough of Manhattan in the City of New York or the courts of the State of New York in each case located in the

Borough of Manhattan in the City of New York (collectively, the “Specified Courts”), and each party irrevocably submits

to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to

which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice

or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other

proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit,

action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such

court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

33

Section

21. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior

written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This

Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures

thereto and hereto were upon the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic

signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act

or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have

been duly and validly delivered and be valid and effective for all purposes. This Agreement may not be amended or modified unless in

writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party

whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect

the construction or interpretation of this Agreement.

Each

of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations

regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 9 and the contribution provisions

of Section 10, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of

Section 9 and Section 10 hereof fairly allocate the risks in light of the ability of the parties to investigate the Company, its affairs

and its business in order to assure that adequate disclosure has been made in the Registration Statement, any preliminary prospectus,

the Time of Sale Prospectus, each free writing prospectus and the Prospectus (and any amendments and supplements to the foregoing), as

contemplated by the Securities Act and the Exchange Act.

34

If

the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof,

whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

If

such make-whole fundamental change effective date or stock price is not set forth in the table above, then:

● if

such stock price is between two stock prices in the table above or the make-whole fundamental

change effective date is between two dates in the table above, then the number of additional

shares will be determined by straight-line interpolation between the numbers of additional

shares set forth for the higher and lower stock prices in the table above or the earlier

and later dates in the table above, based on a 365- or 366-day year, as applicable; and

● if

RE:

Celcuity

Inc. (the “Company”)

Ladies

and Gentlemen:

The

undersigned is an owner of shares of common stock, par value $0.001 per share, of the Company (“Shares”) or of securities

convertible into or exchangeable or exercisable for Shares. The Company proposes to enter into (i) an underwriting agreement (the “Equity

Underwriting Agreement”) with Jefferies LLC (“Jefferies”), J.P. Morgan Securities LLC (“J.P. Morgan”)

TD Securities (USA) LLC (“TD Cowen”) and Guggenheim Securities, LLC (together with Jefferies, J.P. Morgan and TD Cowen,

the “Representatives”), acting as the representatives of the underwriters (the “Underwriters”),

providing for the public offering (the “Equity Offering”) by the several Underwriters of the Shares and (ii) an underwriting

agreement (the “Debt Underwriting Agreement” and together with the Equity Underwriting Agreement, the “Underwriting

Agreements”) with the Representatives, acting as the representatives of the Underwriters, providing for the public offering

(the “Debt Offering” and together with the Equity Offering, the “Offerings”) by the several Underwriters

of convertible senior notes (the “Notes”, and together with the Shares, the “Securities”). The

Notes will be convertible into Shares. In the event that the Company and the Representatives determine to only commence the Equity Offering,

then references herein to the term “Underwriting Agreements,” “Offerings” and “Securities” shall

mean the “Equity Underwriting Agreement,” “Equity Offering” and “Shares,” respectively, while if

such parties determine to only commence the Debt Offering, then references herein to the term “Underwriting Agreements,”

“Offerings” and “Securities” shall mean the “Debt Underwriting Agreement,” “Debt Offering”

and “Notes,” respectively. The undersigned recognizes that the Offerings will benefit each of the Company and the undersigned.

The undersigned acknowledges that the Underwriters are relying on the representations and agreements of the undersigned contained in

this letter agreement in conducting the Offerings and, at a subsequent date, in entering into Underwriting Agreements for the Offerings

and other underwriting arrangements with the Company with respect to the Offerings.

Annex

A sets forth definitions for capitalized terms used in this letter agreement that are not defined in the body of this letter agreement.

Those definitions are a part of this letter agreement.

In

consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,

the undersigned hereby agrees that, during the Lock-up Period, the undersigned will not (and will cause any Family Member not to), without

the prior written consent of the Representatives, which may withhold their consent in their sole discretion:

● Sell

or Offer to Sell any Shares or Related Securities currently or hereafter owned either of

record or beneficially (as defined in Rule 13d-3 under the Exchange Act) by the undersigned

or such Family Member,

● enter

into any Swap,

● make

any demand for, or exercise any right with respect to, the registration under the Securities

Act of the offer and sale of any Shares or Related Securities, or cause to be filed a registration

statement, prospectus or prospectus supplement (or an amendment or supplement thereto) with

respect to any such registration, or

● publicly

announce any intention to do any of the foregoing.

The

foregoing restrictions will not apply to the registration of the offer and sale of the Securities, and the sale of the Securities to

the Underwriters, in each case as contemplated by the Underwriting Agreements. In addition, the foregoing restrictions shall not apply

to the transfer of Shares or Related Securities (i) by gift, (ii) by will or intestate succession, (iii) to a trust whose beneficiaries

consist exclusively of one or more of the undersigned and/or a Family Member, (iv) if the undersigned is a corporation, partnership,

limited liability company, trust or other business entity, (A) to another corporation, partnership, limited liability company, trust

or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933,

as amended) of the undersigned or (B) as distributions of Shares or Related Securities to limited partners, limited liability company

members or stockholders of the undersigned, or (v) if the undersigned is a trust, to the beneficiary of such trust; provided, however,

that in each case set forth in (i) through (v) above, it shall be a condition to such transfer that:

● each

transferee executes and delivers to the Representatives an agreement in form and substance

satisfactory to the Representatives stating that such transferee is receiving and holding

such Shares and/or Related Securities subject to the provisions of this letter agreement

and agrees not to Sell or Offer to Sell such Shares and/or Related Securities, engage in

any Swap or engage in any other activities restricted under this letter agreement except

in accordance with this letter agreement (as if such transferee had been an original signatory

hereto), and

● prior

to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange

Act by any party to the transfer (donor, donee, transferor or transferee) shall be required,

or made voluntarily, reporting a reduction in beneficial ownership of Shares in connection

with such transfer (other than any such disclosure required to be made by applicable law,

provided, however, any such filing will indicate by footnote disclosure otherwise the nature

of the transfer or disposition).

2

In

addition, the foregoing will not apply to (i) the exercise of stock options granted pursuant to the Company’s equity incentive

plans disclosed in the Company’s public filings or the exercise of outstanding warrants disclosed in the Company’s public

filings; provided that such restrictions shall apply to any Shares issued upon such exercise; (ii) the establishment of any contract,

instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange

Act; provided that no sales of Shares or Related Securities will be made pursuant to such a Plan prior to the expiration of the Lock-up

Period, and to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on

behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement

to the effect that no transfer of Shares may be made under such Plan during the Lock-up Period or (iii) sales or transfers made pursuant

to any Plan for the transfer of Shares or Related Securities entered into by the undersigned prior to the date of this letter agreement

and such Plan has been provided to the Representatives prior to the date hereof; provided that, to the extent a public announcement or

filing under the Exchange Act, if any, is required or voluntarily made by or on behalf of the undersigned or the Company regarding any

such sales or transfers, such announcement or filing shall include a statement to the effect that the sale or transfer was made pursuant

to a trading plan established pursuant to Rule 10b5-1.

The

undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar

against the transfer of Shares or Related Securities held by the undersigned and the undersigned’s Family Members, if any, except

in compliance with the foregoing restrictions.

With

respect to the Offerings only, the undersigned waives any registration rights relating to registration under the Securities Act of the

offer and sale of any Securities and/or any Related Securities owned either of record or beneficially by the undersigned, including any

rights to receive notice of the Offerings. The Company shall be a beneficiary of, and entitled to rely upon, the foregoing waiver for

all purposes.

The

undersigned confirms that the undersigned has not, and has no knowledge that any Family Member has, directly or indirectly, taken any

action designed to or that might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security

of the Company to facilitate the sale of the Securities. The undersigned will not, and will cause any Family Member not to take, directly

or indirectly, any such action.

The

undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters

solicited any action from the undersigned with respect to the Offerings and the undersigned has consulted their own legal, accounting,

financial, regulatory and tax advisors to the extent deemed appropriate.

Whether

or not the Offerings occur as currently contemplated or at all depends on market conditions and other factors. The Offerings will only

be made pursuant to the Underwriting Agreements, the terms of which are subject to negotiation between the Company and the Underwriters.

Notwithstanding

anything to the contrary contained herein, this letter agreement will automatically terminate and the undersigned will be released from

all obligations hereunder upon the earliest to occur, if any, of (i) the Company advises the Representatives in writing, prior to the

execution of the Underwriting Agreements, that it has determined not to proceed with the Offerings, (ii) the Underwriting Agreements

are executed but are terminated (other than the provisions thereof which survive termination) prior to payment for and delivery of the

Securities to be sold thereunder, or (iii) the Underwriting Agreements are not executed on or before June 30, 2026.

3

The

undersigned hereby represents and warrants that the undersigned has full power, capacity, and authority to enter into this letter agreement.

This letter agreement is irrevocable and will be binding on the undersigned and the successors, heirs, personal representatives and assigns

of the undersigned. This letter agreement may be delivered via facsimile, electronic mail (including pdf or any electronic signature

complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.com) or other transmission method and any counterpart

so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

This

letter agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very

truly yours,

Section

1.04 Scope of Supplemental Indenture.

This

Supplemental Indenture supplements the provisions of the Base Indenture, to which provisions reference is hereby made. The changes, modifications

and supplements to the Base Indenture effected by this Supplemental Indenture will be applicable only with respect to, and will only

govern the terms of, the Notes, which may be issued from time to time, and will not apply to any other Securities that may be issued

under the Base Indenture unless a supplemental indenture with respect to such other securities specifically incorporates such changes,

modifications and supplements. For all purposes under the Base Indenture, the Notes will constitute a single series of Notes, and with

regard to any matter requiring the consent under the Base Indenture of Holders of multiple Series of Notes voting together as a single

class, the consent of Holders of the Notes voting as a separate class will also be required and the same threshold will apply. The provisions

of this Supplemental Indenture will supersede any conflicting provisions in the Base Indenture.

Article

2. THE NOTES

Section

2.01 Form, Dating and Denominations.

The

Notes and the Trustee’s certificate of authentication will be substantially in the form set forth in Exhibit A. The Notes

will bear the legends required by Section 2.08 and may bear notations, legends or endorsements required by law, stock exchange

rule or usage or the Depositary. Each Note will be dated as of the date of its authentication.

Except

to the extent otherwise provided in a Company Order delivered to the Trustee in connection with the issuance and authentication thereof,

the Notes will be issued initially in the form of one or more Global Notes. Global Notes may be exchanged for Physical Notes only as

provided in Section 2.11 of the Base Indenture; provided, however, that the Company, in its sole discretion, may permit

the exchange of any beneficial interest in a Global Note for one or more Physical Notes at the request of the owner of such beneficial

interest.

The

Notes will be issuable only in registered form without interest coupons and only in Authorized Denominations.

-12-

Each

certificate representing a Note will bear a unique registration number that is not affixed to any other certificate representing another

outstanding Note.

The

terms contained in the Notes constitute part of the Indenture, and, to the extent applicable, the Company and the Trustee, by their execution

and delivery of this Supplemental Indenture, agree to such terms and to be bound thereby; provided, however, that, to the

extent that any provision of any Note conflicts with the provisions of the Indenture, the provisions of the Indenture will control for

purposes of the Indenture and such Note.

Section

2.02 INITIAL NOTES AND ADDITIONAL NOTES.

(A)

Initial Notes. On the Issue Date, there will be originally issued five hundred seventy five million dollars ($575,000,000) aggregate

principal amount of Notes, subject to the provisions of the Indenture (including Section 2.04 of the Base Indenture). Notes issued pursuant

to the Underwriting Agreement, and any Notes issued in exchange therefor or in substitution thereof, are referred to in the Indenture

as the “Initial Notes.”

(B)

Additional Notes. Without the consent of any Holder, the Company may, subject to the provisions of the Indenture (including Section

2.04 of the Base Indenture), originally issue additional Notes with the same terms as the Initial Notes (except, to the extent applicable,

with respect to the date on which interest begins to accrue on such additional Notes and the first Interest Payment Date of such additional

Notes), which additional Notes will, subject to the foregoing, be considered to be part of the same series of, and rank equally and ratably

with all other, Notes issued under this Supplemental Indenture; provided, however, that if any such additional Notes (and

any Notes that are resold after such Notes have been purchased or otherwise acquired by the Company or its Subsidiaries) are not fungible

with other Notes issued under this Supplemental Indenture for U.S. federal income tax purposes, for U.S. federal securities law purposes

or for purposes of the Depositary Procedures, then such additional or resold Notes will be identified by one or more separate CUSIP numbers

or by no CUSIP number. In authenticating additional Notes, the Trustee will receive:

(i)

a copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and form of the Notes were established,

and if the terms and form of such Notes are established by an Officer’s Certificate pursuant to general authorization of the Board

of Directors, such Officer’s Certificate;

(ii)

an executed supplemental indenture, if any; and

(iii)

an Opinion of Counsel which will state:

(1)

that the form and terms of such Notes have been established in conformity with the provisions of the Indenture; and

(2)

that such Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions

specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, enforceable in accordance

with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting

the enforcement of creditors’ rights and to general equity principles.

-13-

Section

2.03 Method of Payment.

(A)

Global Notes. The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity

Date, Redemption on a Redemption Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash

Conversion Consideration for, any Global Note to the Depositary by wire transfer of immediately available funds no later than the time

the same is due as provided in the Indenture.

(B)

Physical Notes. The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity

Date, Redemption on a Redemption Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash

Conversion Consideration for, any Physical Note no later than the time the same is due as provided in the Indenture as follows: (i) if

the principal amount of such Physical Note is at least two million dollars ($2,000,000) (or such lower amount as the Company may choose

in its sole and absolute discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent

or the Trustee, no later than the time set forth in the immediately following sentence, a written request that the Company make such

payment by wire transfer to an account of such Holder within the United States specified in such request, by wire transfer of immediately

available funds to such account; and (ii) in all other cases, by check mailed to the address of the Holder of such Physical Note entitled

to such payment as set forth in the Register. To be timely, such written request must be so delivered no later than the Close of Business

on the following date: (x) with respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular

Record Date; (y) with respect to any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other payment,

the date that is fifteen (15) calendar days immediately before the date such payment is due.

Section

2.04 Accrual of Interest; Defaulted Amounts; When Payment Date is Not a BUSINESS DAY.

(A)

Accrual of Interest. Each Note will accrue interest at a rate per annum equal to 0.250% (the “Stated Interest”),

plus any Special Interest that may accrue pursuant to Section 7.03. Stated Interest on each Note will (i) accrue from, and including,

the most recent date to which Stated Interest has been paid or duly provided for (or, if no Stated Interest has theretofore been paid

or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest

will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Section

4.02(D), Section 4.03(E) and Section 5.02(D) (but without duplication of any payment of interest), payable semi-annually

in arrears on each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such

Note, to the Holder of such Note as of the Close of Business on the immediately preceding Regular Record Date. Stated Interest, and,

if applicable, Special Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(B)

Defaulted Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before

the due date therefor as provided in the Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such

Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise entitled to such payment; (ii) to the extent

lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per

annum at which Stated Interest accrues, from, and including, such due date to, but excluding, the date of payment of such Defaulted Amount

and Default Interest; and (iii) such Defaulted Amount and Default Interest will be paid, at the Company’s election, as provided

in clause (i) or (ii) below.

-14-

(i)

Payment of Default Amounts on a Special Payment Date. The Company will have the right to pay such Defaulted Amount and Default

Interest on a payment date selected by the Company to the Holder of such Note as of the Close of Business on a special record date selected

by the Company, provided that (1) such special record date is no more than fifteen (15), nor less than ten (10), calendar days

before such payment date; and (2) at least fifteen (15) calendar days before such special record date, the Company sends notice to the

Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest

to be paid on such payment date.

(ii)

Payment of Default Amount in Any Other Lawful Manner. If not paid in accordance with Section 2.04(B)(i), such Defaulted

Amount and Default Interest will be paid by the Company 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, if, after notice given by the Company to the Trustee of the proposed payment pursuant

to this Section 2.04(B)(ii), such manner of payment will be deemed practicable by the Trustee.

(C)

Delay of Payment When Payment Date Is Not a Business Day. If the due date for a payment on a Note as provided in the Indenture

is not a Business Day, then, notwithstanding anything to the contrary in the Indenture or the Notes, such payment may be made on the

immediately following Business Day with the same force and effect as if such payment were made on such due date (and, for the avoidance

of doubt, no interest will accrue on such payment as a result of the related delay). Solely for purposes of the immediately preceding

sentence, a day on which the applicable place of payment is authorized or required by law or executive order to close or be closed will

be deemed not to be a “Business Day.”

(D)

Special Provision for Global Notes. If the first date on which any Special Interest begins to accrue on a Global Note is on or

after the fifth (5th) Business Day before a Regular Record Date and before the next Interest Payment Date, then, notwithstanding anything

to the contrary in the Indenture or the Notes, the amount thereof accruing in respect of the period from, and including, such first date

to, but excluding, such Interest Payment Date will not be payable on such Interest Payment Date but will instead be deemed to accrue

(without duplication) entirely on such Interest Payment Date and be payable on the immediately succeeding Interest Payment Date (and,

for the avoidance of doubt, no interest will accrue as a result of the related delay).

Section

2.05 Registrar, Paying Agent and Conversion Agent.

This

Section 2.05 will apply to the Notes in lieu of Section 4.02 of the Base Indenture, which will be deemed to be replaced with this

Section 2.05, mutatis mutandis.

(A)

Generally. The Company will maintain (i) an office or agency in the continental United States where Notes may be presented for

registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States

where Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental United

States where Notes may be presented for Conversion (the “Conversion Agent”). If the Company fails to maintain a Registrar,

Paying Agent or Conversion Agent, then the Trustee will act as such and will receive compensation therefor in accordance with the Indenture

and any other agreement between the Trustee and the Company. For the avoidance of doubt, the Company or any of its Subsidiaries may act

as Registrar, Paying Agent or Conversion Agent, without prior notice to Holders. Notwithstanding anything to the contrary in this Section

2.05(A), each of the Registrar, Paying Agent and Conversion Agent with respect to any Global Note must at all times be a Person that

is eligible to act in that capacity under the Depositary Procedures.

-15-

(B)

Duties of the Registrar. The Registrar will keep a record (the “Register”) of the names and addresses of the

Holders, the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and Conversion of Notes. Absent manifest error,

the entries in the Register will be conclusive and the Company and the Trustee may treat each Person whose name is recorded as a Holder

in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted into written

form reasonably promptly.

(C)

Co-Agents; Company’s Right to Appoint Successor Registrars, Paying Agents and Conversion Agents. The Company may appoint

one or more co-Registrars, co-Paying Agents and co-Conversion Agents, each of whom will be deemed to be a Registrar, Paying Agent or

Conversion Agent, as applicable, under the Indenture. Subject to Section 2.05(A), the Company may change any Registrar, Paying

Agent or Conversion Agent (including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any Holder.

The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to

the Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions

of the Indenture that relate to such Note Agent.

(D)

Initial Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar and the initial Conversion

Agent and designates the office of the Trustee at U.S. Bank Trust Company, National Association, West Side Flats St Paul, 60 Livingston

Ave, Saint Paul, MN 55107 | EP-MN-S3MC, Attention: Q. DePompolo (Celcuity Inc. Administrator) as the office for the same (or such other

address as the Trustee or applicable Note Agent may designate from time to time by notice to the Holders and the Company).

Section

2.06 Paying Agent and Conversion Agent to Hold Property in Trust.

This

Section 2.06 will apply to the Notes in lieu of Section 4.03 of the Base Indenture, which will be deemed to be replaced with this

Section 2.06 , mutatis mutandis.

The

Company will require each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent will (A)

hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery

due on the Notes; and (B) notify the Trustee of any default by the Company in making any such payment or delivery. The Company, at any

time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable,

all money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent (if not the Company

or any of its Subsidiaries) will have no further liability for such money or property. If the Company or any of its Subsidiaries acts

as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund for the benefit of the Holders or the

Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in the Indenture or the Notes

to the Paying Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to the Paying Agent

or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed

to refer to cash or other property so segregated and held separately, or to the segregation and separate holding of such cash or other

property, respectively. Upon the occurrence of any event pursuant to clause (viii) or (ix) of Section 7.01(A) with

respect to the Company (or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will

serve as the Paying Agent or Conversion Agent, as applicable, for the Notes.

-16-

Section

2.07 Holder Lists.

If

the Trustee is not the Registrar, then the Company will furnish to the Trustee, no later than seven (7) Business Days before each Interest

Payment Date, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may

reasonably require, of the names and addresses of the Holders.

Section

2.08 Legends.

(A)

Global Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with the Indenture,

required by the Depositary for such Global Note).

(B)

Non-Affiliate Legend. Each Note will bear the Non-Affiliate Legend.

(C)

Other Legends. A Note may bear any other legend or text, not inconsistent with the Indenture, as may be required by applicable

law or by any securities exchange or automated quotation system on which such Note is traded or quoted.

(D)

Acknowledgment and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend required by this Section

2.08 will constitute such Holder’s acknowledgment of, and agreement to comply with, the restrictions set forth in such legend.

Section

2.09 Certain Transfer Restrictions on Notes Subject to Conversion, Redemption or Repurchase.

Notwithstanding

anything to the contrary in the Indenture or the Notes, the Company, the Trustee and the Registrar will not be required to register

the transfer of or exchange any Note that (i) has been surrendered for Conversion, except to the extent that any portion of such

Note is not subject to Conversion; (ii) has been selected for Redemption pursuant to a Redemption Notice, except to the

extent that any portion of such Note is not subject to Redemption or the Company fails to pay the applicable Redemption Price when

due; or (iii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section

4.02(F), except to the extent that any portion of such Note is not subject to such notice or the Company fails to pay the

applicable Fundamental Change Repurchase Price when due.

Section

2.10 Exchange and Cancellation of Notes to Be Converted, Redeemed or Repurchased.

(A)

Partial Conversions of Physical Notes and Partial Redemptions or Repurchases of Physical Notes. If only a portion of a Physical

Note of a Holder is to be Converted pursuant to Article 5, redeemed pursuant to a Redemption or repurchased pursuant to a Repurchase

Upon Fundamental Change or, then, as soon as reasonably practicable after such Physical Note is surrendered for such Conversion, redemption

or repurchase, as applicable, the Company will cause such Physical Note to be exchanged, pursuant and subject to Section 2.05 of the

Base Indenture, for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal

to the principal amount of such Physical Note that is not to be so Converted, redeemed or repurchased, as applicable, and deliver such

Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so Converted,

redeemed or repurchased, as applicable, which Physical Note will be Converted, redeemed or repurchased, as applicable, pursuant to the

terms of the Indenture; provided, however, that the Physical Note referred to in this clause (ii) need not be issued at any time

after which such principal amount subject to such Conversion or repurchase, as applicable, is deemed to cease to be outstanding pursuant

to Section 2.13.

-17-

(B)

Cancellation of Notes that Are Converted, Redeemed Pursuant to a Redemption and Notes that Are Repurchased Pursuant to a Repurchase

Upon Fundamental Change.

(i)

Physical Notes. If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to Section 2.10(A))

of a Holder is to be Converted pursuant to Article 5, redeemed pursuant to a Redemption or repurchased pursuant to a Repurchase

Upon Fundamental Change, then, promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding

pursuant to Section 2.13 and the time such Physical Note is surrendered for such Conversion, redemption or repurchase, as applicable,

(1) such Physical Note will be cancelled pursuant to Section 2.08 of the Base Indenture; and (2) in the case of a partial Conversion,

redemption or repurchase, as applicable, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate,

in each case in accordance with Section 2.04 of the Base Indenture, one or more Physical Notes that (x) are in Authorized Denominations

and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so Converted, redeemed or

repurchased, as applicable; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by Section 2.08.

(ii)

Global Notes. If a Global Note (or any portion thereof) is to be Converted pursuant to Article 5, redeemed pursuant to

a Redemption or repurchased pursuant to a Repurchase Upon Fundamental Change, then, promptly after the time such Note (or such portion)

is deemed to cease to be outstanding pursuant to Section 2.13, the Trustee will reflect a decrease of the principal amount of

such Global Note in an amount equal to the principal amount of such Global Note to be so Converted, redeemed or repurchased, as applicable,

by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if the

principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.08 of the Base Indenture).

Section

2.11 Registered holders; certain rights with respect to global notes.

Except

to the extent rights hereunder are expressly granted to owners of beneficial interests of Notes, only the Holder of a Note will have

rights under the Indenture as the owner of such Note. Without limiting the generality of the foregoing, Depositary Participants will

have no rights as such under the Indenture with respect to any Global Note held on their behalf by the Depositary or its nominee, or

by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and their respective agents, may treat the Depositary

as the absolute owner of such Global Note for all purposes whatsoever; provided, however, that (A) the Holder of any Global

Note may grant proxies and otherwise authorize any Person, including Depositary Participants and Persons that hold interests in Notes

through Depositary Participants, to take any action that such Holder is entitled to take with respect to such Global Note under the Indenture

or the Notes; and (B) the Company and the Trustee, and their respective agents, may give effect to any written certification, proxy or

other authorization furnished by the Depositary.

Section

2.12 Notes Held by the Company or its Affiliates.

Without

limiting the generality of Section 2.13, in determining whether the Holders of the required aggregate principal amount of Notes

have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates will be deemed not to be outstanding;

provided, however, that, for purposes of determining whether the Trustee is protected in relying on any such direction,

waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned will be so disregarded.

-18-

Section

2.13 Outstanding Notes.

(A)

Generally. The Notes that are outstanding at any time will be deemed to be those Notes that, at such time, have been duly executed

and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to

the Trustee for cancellation in accordance with Section 2.08 of the Base Indenture; (ii) assigned a principal amount of zero by notation

on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such Note;

(iii) paid in full (including upon Conversion) in accordance with the Indenture; or (iv) deemed to cease to be outstanding to the extent

provided in, and subject to, clause (B), (C) or (D) of this Section 2.13.

(B)

Replaced Notes. If a Note is replaced pursuant to Section 2.07 of the Base Indenture, then such Note will cease to be outstanding

at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held

by a “bona fide purchaser” under applicable law.

(C)

Maturing Notes and Notes Called for Redemption or Subject to Repurchase. If, on a Redemption Date, a Fundamental Change Repurchase

Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Redemption Price, Fundamental Change Repurchase

Price or principal amount, respectively, together, in each case, with the aggregate interest (if any), in each case due on such date,

then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be redeemed or repurchased,

or that mature, on such date will be deemed, as of such date, to cease to be outstanding, except to the extent provided in Section

4.02(D), 4.03(E) or 5.02(D); and (ii) the rights of the Holders of such Notes (or such portions thereof), as such,

will terminate with respect to such Notes (or such portions thereof), other than the right to receive the Redemption Price, Fundamental

Change Repurchase Price or principal amount, as applicable, of, and accrued and unpaid interest on, such Notes (or such portions thereof),

in each case as provided in the Indenture.

(D)

Notes to Be Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof) to be Converted,

such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant

to Section 5.03(B) or Section 5.02(D), upon such Conversion) be deemed to cease to be outstanding, except to the extent

provided in Section 5.02(D) or Section 5.08.

(E)

Cessation of Accrual of Interest. Except as provided in Section 4.02(D), 4.03(E) or 5.02(D), interest will

cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.13, to cease to

be outstanding, unless there occurs a default in the payment or delivery of any cash or other property due on such Note.

Section

2.14 Repurchases by the Company.

Without

limiting the generality of Section 2.08 of the Base Indenture, the Company may, from time to time, repurchase Notes in open market purchases

or in negotiated transactions without delivering prior notice to Holders. Notes that the Company or any of its Subsidiaries have purchased

or otherwise acquired will be deemed to remain outstanding (except to the extent provided in Section 2.12) until such time as

such Notes are delivered to the Trustee for cancellation.

Section

2.15 Cusip and isin Numbers.

This

Section 2.15 will apply to the Notes in lieu of Section 2.12 of the Base Indenture, which will be deemed to be replaced with this

Section 2.15, mutatis mutandis.

-19-

The

Company may use one or more CUSIP or ISIN numbers to identify any of the Notes, and, if so, the Company and the Trustee will use such

CUSIP or ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as to the

correctness or accuracy of any such CUSIP or ISIN number; and (ii) the effectiveness of any such notice will not be affected by any defect

in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s)

identifying any Notes.

Trustee’s Disclaimer. The Trustee need not determine whether the Company has filed any material via the EDGAR system (or

such successor). The sending or filing of reports, information and documents to the Trustee pursuant to Section 3.02(A) is for

informational purposes only and the receipt of such reports and documents will not constitute actual or constructive notice to the Trustee

of any information contained, or determinable from information contained, therein, including the Company’s compliance with any

of its covenants under the Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

The Trustee will not be obligated to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with the

Section

4.02 Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change.

(A)

Right of Holders to Require the Company to Repurchase Notes Upon a Fundamental Change. Subject to the other terms of this Section

4.02, if a Fundamental Change occurs, then each Holder will have the right (the “Fundamental Change Repurchase Right”)

to require the Company to repurchase such Holder’s Notes (or any portion thereof in an Authorized Denomination) on the Fundamental

Change Repurchase Date for such Fundamental Change for a cash purchase price equal to the Fundamental Change Repurchase Price.

(B)

Repurchase Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration

has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including as a result

of the payment of the related Fundamental Change Repurchase Price, and any related interest pursuant to the proviso to the first sentence

of Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to

this Section 4.02; and (ii) the Company will cause any Notes theretofore surrendered for such Repurchase Upon Fundamental Change

to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer

to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary

Procedures).

(C)

Fundamental Change Repurchase Date. The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of

the Company’s choosing that is no more than thirty-five (35), nor less than twenty (20), Business Days after the date the Company

sends the related Fundamental Change Notice pursuant to Section 4.02(E).

(D)

Fundamental Change Repurchase Price. The Fundamental Change Repurchase Price for any Note to be repurchased upon a Repurchase

Upon Fundamental Change following a Fundamental Change is an amount in cash equal to the principal amount of such Note plus accrued and

unpaid interest on such Note to, but excluding, the Fundamental Change Repurchase Date for such Fundamental Change; provided,

however, that if a such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment

Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Repurchase

Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that

would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained

outstanding through such Interest Payment Date, if such Fundamental Change Repurchase Date is before such Interest Payment Date); and

(ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental

Change Repurchase Date. For the avoidance of doubt, if an Interest Payment Date is not a Business Day within the meaning of Section

2.04(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then

(x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.04(C),

on the next Business Day to Holders as of the Close of Business on the immediately preceding Regular Record Date; and (y) the Fundamental

Change Repurchase Price will include interest on the Notes to be repurchased from, and including, such Interest Payment Date.

(E)

Fundamental Change Notice. On or before the twentieth (20th) calendar day after the effective date of a Fundamental Change, the

Company will send to each Holder, the Trustee, the Conversion Agent (if other than the Trustee) and the Paying Agent a notice of such

Fundamental Change (a “Fundamental Change Notice”).

-22-

Such

Fundamental Change Notice must state:

(i)

briefly, the events causing such Fundamental Change;

(ii)

the effective date of such Fundamental Change;

(iii)

the procedures that a Holder must follow to require the Company to repurchase its Notes pursuant to this Section 4.02, including

the deadline for exercising the Fundamental Change Repurchase Right and the procedures for submitting and withdrawing a Fundamental Change

Repurchase Notice;

(iv)

the Fundamental Change Repurchase Date for such Fundamental Change;

(v)

the Fundamental Change Repurchase Price per $1,000 principal amount of Notes for such Fundamental Change (and, if such Fundamental Change

Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, the amount, manner and timing of the

interest payment payable pursuant to the proviso to the first sentence of Section 4.02(D));

(vi)

the name and address of the Paying Agent and the Conversion Agent;

(vii)

the Conversion Rate in effect on the date of such Fundamental Change Notice and a description and quantification of any adjustments to

the Conversion Rate that may result from such Fundamental Change (including pursuant to Section 5.07);

(viii)

that Notes for which a Fundamental Change Repurchase Notice has been duly tendered and not duly withdrawn must be delivered to the Paying

Agent for the Holder thereof to be entitled to receive the Fundamental Change Repurchase Price;

(ix)

that Notes (or any portion thereof) that are subject to a Fundamental Change Repurchase Notice that has been duly tendered may be Converted

only if such Fundamental Change Repurchase Notice is withdrawn in accordance with the Indenture; and

(x)

the CUSIP and ISIN numbers, if any, of the Notes.

Neither

the failure to deliver a Fundamental Change Notice nor any defect in a Fundamental Change Notice will limit the Fundamental Change Repurchase

Right of any Holder or otherwise affect the validity of any proceedings relating to any Repurchase Upon Fundamental Change.

(F)

Procedures to Exercise the Fundamental Change Repurchase Right.

(i)

Delivery of Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its Fundamental Change Repurchase Right

for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent:

(1)

before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or such later time

as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and

(2)

such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer (if such Note is a Global Note).

-23-

(3)

The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase Notice that it receives.

(ii)

Contents of Fundamental Change Repurchase Notices. Each Fundamental Change Repurchase Notice with respect to a Note must state:

(1)

if such Note is a Physical Note, the certificate number of such Note;

(2)

the principal amount of such Note to be repurchased, which must be an Authorized Denomination; and

(3)

that such Holder is exercising its Fundamental Change Repurchase Right with respect to such principal amount of such Note; provided,

however, that if such Note is a Global Note, then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures

(and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the

requirements of this Section 4.02(F)).

(iii)

Withdrawal of Fundamental Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect

to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at

any time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or, if the

Company fails to pay the related Fundamental Change Repurchase Price for such Note when due, at any time before such Fundamental Change

Repurchase Price is paid in full). Such withdrawal notice must state:

(1)

if such Note is a Physical Note, the certificate number of such Note;

(2)

the principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and

(3)

the principal amount of such Note, if any, that remains subject to such Fundamental Change Repurchase Notice, which must be an Authorized

Denomination;

(4)

provided, however, that if such Note is a Global Note, then such withdrawal notice must comply with the Depositary Procedures

(and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of

this Section 4.02(F)).

Upon

receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly deliver a copy

of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof

in accordance with Section 2.10, treating such Note as having been then surrendered for partial repurchase in the amount set forth

in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to

any Global Note, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial

interest in such Note in accordance with the Depositary Procedures).

-24-

(G)

Payment of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to deposit the Fundamental

Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase

Price for a Note (or portion thereof) to be repurchased pursuant to a Repurchase Upon Fundamental Change to be paid to the Holder thereof

on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to the

Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying

Agent, of such Holder’s beneficial interest in such Note to be repurchased are complied with (in the case of a Global Note). For

the avoidance of doubt, interest payable pursuant to the proviso to the first sentence of Section 4.02(D) on any Note to be repurchased

pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to such proviso regardless of whether such Note is delivered or

such Depositary Procedures are complied with pursuant to the first sentence of this Section 4.02(G).

(H)

Third Party May Conduct Repurchase Offer In Lieu of the Company. Notwithstanding anything to the contrary in this Section 4.02,

the Company will be deemed to satisfy its obligations under this Section 4.02 if (i) one or more third parties conduct any Repurchase

Upon Fundamental Change and related offer to repurchase Notes otherwise required by this Section 4.02 in a manner that would have

satisfied the requirements of this Section 4.02 if conducted directly by the Company; and (ii) an owner of a beneficial interest

in any Note repurchased by such third party or parties will not receive a lesser amount (including as a result of withholding or other

similar taxes) than such owner would have received had the Company repurchased such Note.

(I)

No Requirement to Conduct an Offer to Repurchase Notes if the Fundamental Change Results in the Notes Becoming Convertible into an

Amount of Cash Exceeding the Fundamental Change Repurchase Price. Notwithstanding anything to the contrary in this Section 4.02,

the Company will not be required to send a Fundamental Change Notice pursuant to Section 4.02(E), or offer to repurchase or repurchase

any Notes pursuant to this Section 4.02, in connection with a Common Stock Change Event that constitutes a Fundamental Change

pursuant to clause (B)(ii) of the definition thereof (regardless of whether such Common Stock Change Event also constitutes a

Fundamental Change pursuant to any other clause of such definition), if (i) the Reference Property of such Common Stock Change Event

consists entirely of cash in U.S. dollars; (ii) immediately after such Fundamental Change, the Notes become Convertible, pursuant to

Section 5.09(A) and, if applicable, Section 5.07, into consideration that consists solely of U.S. dollars in an amount

per $1,000 aggregate principal amount of Notes that equals or exceeds the Fundamental Change Repurchase Price per $1,000 aggregate principal

amount of Notes (calculated (x) assuming that such Fundamental Change Repurchase Price includes accrued and unpaid interest to, but excluding,

the latest possible Fundamental Change Repurchase Date for such Fundamental Change; and (y) without regard to the proviso to the first

sentence of Section 4.02(D)); and (iii) the Company timely sends the notice relating to such Fundamental Change and Common Stock

Change Event required pursuant to Section 5.09(B), and includes, in such notice, the information set forth in clauses (i),

(ii), (vi), (vii) and (x) of Section 4.02(E) and a statement that the Company is relying on this Section 4.02(I).

(J)

Compliance with Applicable Securities Laws. To the extent applicable, the Company will comply, in all material respects, with

all federal and state securities laws in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and

14e-1 under the Exchange Act and filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase

Upon Fundamental Change in the manner set forth in the Indenture; provided, however, that, to the extent that the Company’s

obligations pursuant to this Section 4.02 conflict with any law or regulation that is applicable to the Company and enacted after

the Issue Date, the Company’s compliance with such law or regulation will not be considered to be a Default of such obligations;

rather, the Company will be deemed to be in compliance with such obligations if the Company complies with its obligation to effect Repurchases

Upon a Fundamental Change in accordance with this Section 4.02, modified as necessary by the Company in good faith to permit compliance

with such law or regulation.

-25-

(K)

Repurchase in Part. Subject to the terms of this Section 4.02, Notes may be repurchased pursuant to a Repurchase Upon Fundamental

Change in part, but only in Authorized Denominations. Provisions of this Section 4.02 applying to the repurchase of a Note in

whole will equally apply to the repurchase of a permitted portion of a Note.

Section

4.03 Right of the Company to Redeem the Notes.

(A)

No Right to Redeem Before August 6, 2029. The Company may not redeem the Notes at its option at any time before August 6, 2029.

(B)

Right to Redeem the Notes on or After August 6, 2029. Subject to the terms of this Section 4.03, the Company has the right,

at its election, to redeem all, or any portion (subject to the Partial Redemption Limitation described below) in an Authorized Denomination,

of the Notes, at any time, and from time to time, on a Redemption Date on or after August 6, 2029 and on or before the thirty-first (31st)

Scheduled Trading Day immediately before the Maturity Date, for a cash purchase price equal to the Redemption Price, but only if the

Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price on (x) each

of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including,

the Trading Day immediately before such Redemption Notice Date; and (y) the Trading Day immediately before such Redemption Notice Date;

provided, however, that the Company will not call less than all of the outstanding Notes for Redemption unless the excess

of the principal amount of Notes outstanding as of the time the Company sends the related Redemption Notice over the aggregate principal

amount of Notes set forth in such Redemption Notice as being subject to such Redemption is at least fifty million dollars ($50,000,000)

(such limitation, the “Partial Redemption Limitation”). For the avoidance of doubt, the calling (or the deemed calling,

as provided in Section 4.03(I)) of any Notes for Redemption will constitute a Make-Whole Fundamental Change with respect to such

Notes called (or deemed called) for Redemption (and not with respect to any other Notes) pursuant to clause (B) of the definition

thereof.

(C)

Redemption Prohibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration

has not been rescinded on or before the Redemption Date (including as a result of the payment of the related Redemption Price, and any

related interest pursuant to the proviso to the first sentence of Section 4.03(E), on such Redemption Date), then (i) the Company

may not call for Redemption or otherwise redeem any Notes pursuant to this Section 4.03; and (ii) the Company will cause any Notes

theretofore surrendered for such Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel

any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such

Notes in accordance with the Depositary Procedures).

(D)

Redemption Date. The Redemption Date for any Redemption will be a Business Day of the Company’s choosing that is no more

than fifty-five (55), nor less than thirty-five (35), Scheduled Trading Days after the Redemption Notice Date for such Redemption.

(E)

Redemption Price. The Redemption Price for any Note called for Redemption is an amount in cash equal to the principal amount of

such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided,

however, that if such Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, then (i)

the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive,

on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to,

but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest

Payment Date, if such Redemption Date is before such Interest Payment Date); and (ii) the Redemption Price will not include accrued and

unpaid interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt, if an Interest Payment Date is not

a Business Day within the meaning of Section 2.04(C) and such Redemption Date occurs on the Business Day immediately after such

Interest Payment Date, then (x) accrued and unpaid interest on Notes to, but excluding, such Interest Payment Date will be paid, in accordance

with Section 2.04(C), on the next Business Day to Holders as of the Close of Business on the immediately preceding Regular Record

Date; and (y) the Redemption Price will include interest on Notes to be redeemed from, and including, such Interest Payment Date.

-26-

(F)

Redemption Notice. To call any Notes for Redemption, the Company must send to each Holder of such Notes a written notice of such

Redemption (a “Redemption Notice”).

Such

Redemption Notice must state:

(i)

that such Notes have been called for Redemption, briefly describing the Company’s Redemption right under the Indenture;

(ii)

the Redemption Date for such Redemption;

(iii)

the Redemption Price per $1,000 principal amount of Notes for such Redemption (and, if the Redemption Date is after a Regular Record

Date and on or before the next Interest Payment Date, the amount, manner and timing of the interest payment payable pursuant to the proviso

to the first sentence of Section 4.03(E));

(iv)

the name and address of the Paying Agent and the Conversion Agent;

(v)

that Notes called for Redemption may be Converted at any time before the Close of Business on the Business Day immediately before the

Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time

as the Company pays such Redemption Price in full);

(vi)

the Conversion Rate in effect on the Redemption Notice Date for such Redemption and a description and quantification of any adjustments

to the Conversion Rate that may result from such Redemption (including pursuant to Section 5.07);

(vii)

the Settlement Method that will apply to all Conversions of Notes with a Conversion Date that occurs on or after such Redemption Notice

Date and on or before the second (2nd) Business Day before such Redemption Date;

(viii)

if applicable, that Conversions of Notes will be settled in the manner set forth in clause (1) of the proviso in Section 5.03(C);

(ix)

that Notes called for Redemption must be delivered to the Paying Agent (in the case of Physical Notes) or the Depositary Procedures must

be complied with (in the case of Global Notes) for the Holder thereof to be entitled to receive the Redemption Price; and

(x)

the CUSIP and ISIN numbers, if any, of the Notes.

On

or before the Redemption Notice Date, the Company will send a copy of such Redemption Notice to the Trustee, the Conversion Agent (if

other than the Trustee) and the Paying Agent (if other than the Trustee).

-27-

(G)

Selection and Conversion of Notes to Be Redeemed in Part.

(i)

If fewer than all Notes then outstanding are called for Redemption, then the Notes to be redeemed will be selected by the Trustee as

follows: (1) in the case of Global Notes, in accordance with the Depositary Procedures; and (2) in the case of Physical Notes, pro rata,

by lot.

(ii)

If only a portion of a Note is subject to Redemption and such Note is Converted in part, then the Converted portion of such Note will

be deemed to be from the portion of such Note that was subject to Redemption, subject, in the case of any Global Note, to the Depositary

Procedures.

(H)

Payment of the Redemption Price. Without limiting the Company’s obligation to deposit the Redemption Price by the time proscribed

by Section 3.01(B), the Company will cause the Redemption Price for a Note (or portion thereof) subject to Redemption to be paid

to the Holder thereof on or before the applicable Redemption Date. For the avoidance of doubt, interest payable pursuant to the proviso

to the first sentence of Section 4.03(E) on any Note (or portion thereof) subject to Redemption must be paid pursuant to such

proviso.

(I)

Special Provisions for Partial Calls. If the Company elects to redeem fewer than all of the outstanding Notes pursuant to this

Section 4.03, and the Holder of any Note, or any owner of a beneficial interest in any Global Note, is reasonably not able to

determine, before the Close of Business on the thirty-second (32nd) Scheduled Trading Day immediately before the Redemption Date for

such Redemption, whether such Note or beneficial interest, as applicable, is to be redeemed pursuant to such Redemption, then such Holder

or owner, as applicable, will be entitled to Convert such Note or beneficial interest, as applicable, at any time before the Close of

Business on the Business Day immediately before such Redemption Date, and each such Conversion will be deemed to be of a Note called

for Redemption for purposes of this Section 4.03 and Section 5.07, and the definition of Make-Whole Fundamental Change.

(J)

Repurchases or Other Acquisitions Other Than by Redemption Not Affected. For the avoidance of doubt, nothing in this Section

4.03 will limit or otherwise apply to any repurchase or other acquisition, by the Company or its Affiliates, or any other Person,

of any Notes not effected by Redemption pursuant to this Section 4.03 (including in open market transactions, private or public

tender or exchange offers or otherwise).

Article

5. THE CONVERSION OF NOTES

Section

5.01 Right to Convert.

(A)

Generally. Subject to the provisions of this Article 5, each Holder may, at its option, Convert such Holder’s Notes

into Conversion Consideration.

(B)

Conversions in Part. Subject to the terms of the Indenture, Notes may be Converted in part, but only in Authorized Denominations.

Provisions of this Article 5 applying to the Conversion of a Note in whole will equally apply to Conversions of a permitted portion

of a Note.

-28-

(C)

When Notes May Be Converted.

(i)

Generally. Subject to Section 5.01(C)(ii), a Note may be Converted only in the following circumstances:

(1)

Conversion Upon Satisfaction of Common Stock Sale Price Condition. A Holder may Convert its Notes during any calendar quarter

(and only during such calendar quarter) commencing after the calendar quarter ending on September 30, 2026, if the Last Reported Sale

Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price for each of at least twenty (20)

Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last Trading

Day of the immediately preceding calendar quarter.

(2) Conversion

Upon Satisfaction of Note Trading Price Condition. A Holder may Convert its Notes during the five (5) consecutive Business Days

immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading Day period, the

“Measurement Period”) if the Trading Price per $1,000 principal amount of Notes, as determined following a

request by a Holder or Holders in accordance with the procedures set forth below, for each Trading Day of the Measurement Period was

less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day

and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is referred to in this Supplemental

Indenture as the “Trading Price Condition.”

The

Trading Price will be determined by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the definition of “Trading

Price.” The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless

the Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids itself)

unless a Holder or Holders provide(s) the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes

would be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the Conversion

Rate. If a Holder or Holders provide(s) such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct

the Bid Solicitation Agent to, determine the Trading Price of the Notes 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 ninety eight percent (98%) of the product

of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. If the Trading

Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and the Conversion Agent (if other

than the Trustee) of the same. If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading

Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported

Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the

Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the same.

(3)

Conversion Upon Specified Corporate Events.

(a)

Certain Distributions. If, before May 1, 2032, the Company elects to:

(I)

distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to

a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence

of a triggering event, except that such rights will be deemed to be distributed under this clause (I) upon their separation from

the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than sixty (60) calendar days

after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than

the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including,

the Trading Day immediately before the date such distribution is announced (determined in the manner set forth in the third paragraph

of Section 5.05(A)(ii)); or

-29-

(II)

distribute, to all or substantially all holders of Common Stock, assets or securities of the Company or rights to purchase the Company’s

securities, which distribution per share of Common Stock has a value, as reasonably determined by the Board of Directors, exceeding ten

percent (10%) of the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before the date such distribution

is announced,

then, in either case, (x) the Company will send written notice of such distribution, and of the related right to Convert

Notes, to Holders, the Trustee and the Conversion Agent (if other than the Trustee) at least thirty-five (35) Scheduled Trading Days

before the Ex-Dividend Date for such distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder

rights plan or the occurrence of any such triggering event under a stockholder rights plan, as soon as reasonably practicable after the

Company becomes aware that such separation or triggering event has occurred or will occur); and (y) once the Company has sent such notice,

Holders may Convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend

Date and the Company’s announcement that such distribution will not take place; provided, however, that the Notes

will not become Convertible pursuant to clause (y) above (but the Company will be required to send notice of such distribution

pursuant to clause (x) above) on account of such distribution if each Holder participates, at the same time and on the same terms

as holders of Common Stock, and solely by virtue of being a Holder, in such distribution without having to Convert such Holder’s

Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the

record date for such distribution; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such

record date.

(b)

Certain Corporate Events. If a Fundamental Change, Make-Whole Fundamental Change (other than a Make-Whole Fundamental Change pursuant

to clause (B) of the definition thereof) or Common Stock Change Event occurs (other than a merger or other business

combination transaction that is effected solely to change the Company’s jurisdiction of incorporation and that does not constitute

a Fundamental Change or a Make-Whole Fundamental Change), then, in each case, Holders may Convert their Notes at any time from, and including,

the effective date of such transaction or event to, and including, the thirty-fifth (35th) Trading Day after such effective date (or,

if such transaction or event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), to, but excluding, the

related Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred

to in the immediately following sentence by the second (2nd) Business Day after such effective date, then the last day on which the Notes

are Convertible pursuant to this sentence will be extended by the number of Business Days from, and including, the second (2nd) Business

Day after the effective date to, but excluding, the date the Company provides such notice. No later than the second (2nd) Business Day

after the effective date, the Company will send written notice to the Holders, the Trustee and the Conversion Agent (if other than the

Trustee) of such transaction or event, such effective date and the related right to Convert Notes.

-30-

(4)

Conversion Upon Redemption. If the Company calls any Note for Redemption, then the Holder of such Note may Convert such Note at

any time before the Close of Business on the Business Day immediately before the related Redemption Date (or, if the Company fails to

pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in

full).

(5)

Conversions During Free Convertibility Period. A Holder may Convert its Notes at any time from, and including, May 1, 2032 until

the Close of Business on the Scheduled Trading Day immediately before the Maturity Date.

For

the avoidance of doubt, the Notes may become Convertible pursuant to any one or more of the preceding sub-paragraphs of this Section

5.01(C)(i) and the Notes ceasing to be Convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will

not preclude the Notes from being Convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i).

(ii)

Limitations and Closed Periods. Notwithstanding anything to the contrary in the Indenture or the Notes:

(1)

Notes may be surrendered for Conversion during a period where the Notes are Convertible pursuant to Section 5.01(C)(i) only after

the Open of Business and before the Close of Business on a day that is a Business Day;

(2)

in no event may any Note be Converted after the Close of Business on the Scheduled Trading Day immediately before the Maturity Date;

(3)

if the Company calls any Note for Redemption pursuant to Section 4.03, then the Holder of such Note may not Convert such Note

after the Close of Business on the Business Day immediately before the applicable Redemption Date, except to the extent the Company fails

to pay the Redemption Price for such Note in accordance with this Supplemental Indenture; and

(4)

if a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.02(F) with respect to any Note, then such

Note may not be Converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in accordance

with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with

this Supplemental Indenture (or a third party fails to make such payment in lieu of the Company in accordance with Section 4.02(H)).

Section

5.02 Conversion Procedures.

(A)

Generally.

(i)

Global Notes. To Convert a beneficial interest in a Global Note that is Convertible pursuant to Section 5.01(C)(i), the

owner of such beneficial interest must (1) comply with the Depositary Procedures for Converting such beneficial interest (at which time

such Conversion will become irrevocable); and (2) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E).

-31-

(ii)

Physical Notes. To Convert all or a portion of a Physical Note that is Convertible pursuant to Section 5.01(C)(i), the

Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the Conversion Notice attached to such Physical

Note or a facsimile of such Conversion Notice; (2) deliver such Physical Note to the Conversion Agent (at which time such Conversion

will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion Agent may require; and

(4) pay any amounts due pursuant to Section 5.02(D) or Section 5.02(E).

(B)

Effect of Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof) to be Converted,

such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest, if any,

due, pursuant to Section 5.03(B)) or 5.02(D), upon such Conversion) be deemed to cease to be outstanding (and, for the

avoidance of doubt, no Person will be deemed to be a Holder of such Note (or such portion thereof) as of the Close of Business on such

Conversion Date), except to the extent provided in Section 5.02(D).

(C)

Holder of Record of Conversion Shares. The Person in whose name any share of Common Stock is issuable upon Conversion of any Note

will be deemed to become the holder of record of such share as of the Close of Business on (i) the Conversion Date for such Conversion,

in the case of Physical Settlement; or (ii) the last VWAP Trading Day of the Observation Period for such Conversion, in the case of Combination

Settlement.

(D)

Interest Payable Upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a Regular Record Date and

before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be

entitled, notwithstanding such Conversion (and, for the avoidance of doubt, notwithstanding anything set forth in the proviso to this

sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have

accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding

through such Interest Payment Date); and (ii) the Holder surrendering such Note for Conversion must deliver to the Conversion Agent,

at the time of such surrender, an amount of cash equal to the amount of such interest referred to in clause (i) above; provided,

however, that the Holder surrendering such Note for Conversion need not deliver such cash (v) with respect to any Note called

for Redemption, if the Company has specified a Redemption Date that is after such Regular Record Date and on or before the Business Day

immediately after such Interest Payment Date; (w) if such Conversion Date occurs after the Regular Record Date immediately before the

Maturity Date; (x) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or

before the Business Day immediately after such Interest Payment Date; or (y) to the extent of any overdue interest or interest that has

accrued on any overdue interest. For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if

a Note is Converted with a Conversion Date that is after the Regular Record Date immediately before the Maturity Date, then the Company

will pay, as provided above, interest that would have accrued on such Note to, but excluding, the Maturity Date (or, if the Maturity

Date is not a Business Day, the next Business Day) as if such Note had not been Converted. For the avoidance of doubt, if the Conversion

Date of a Note to be Converted is on an Interest Payment Date, then the Holder of such Note at the Close of Business on the Regular Record

Date immediately before such Interest Payment Date will be entitled to receive, on such Interest Payment Date, the unpaid interest that

has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when surrendered for Conversion, need not be accompanied

by any cash amount pursuant to the first sentence of this Section 5.02(D).

-32-

(E)

Taxes and Duties. If a Holder Converts a Note, the Company will pay or cause to be paid any documentary, stamp or similar issue

or transfer tax or duty due on the issue or delivery of any shares of Common Stock upon such Conversion; provided, however,

that if any tax or duty is due because such Holder requested such shares to be registered in a name other than such Holder’s name,

then such Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent

may refuse to deliver any such shares to be issued in a name other than that of such Holder.

(F)

Conversion Agent to Notify Company of Conversions. If any Note is submitted for Conversion to the Conversion Agent or the Conversion

Agent receives any notice of Conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee

(if other than the Conversion Agent) of such occurrence, together with any other information reasonably requested by the Company, and

will cooperate with the Company to determine the Conversion Date for such Note.

Section

5.03 Settlement Upon Conversion.

(A)

Settlement Method. Upon the Conversion of any Note, the Company will settle such Conversion by paying or delivering, as applicable

and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional

shares, as provided in Section 5.03(B)(i)(1) (a “Physical Settlement”); (y) solely cash as provided in Section

5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable,

with cash in lieu of fractional shares, as provided in Section 5.03(B)(i)(3) (a “Combination Settlement”).

(i)

The Company’s Right to Elect Settlement Method. The Company will have the right to elect the Settlement Method applicable

to any Conversion of a Note; provided, however, that:

(1)

subject to clause (3) below, all Conversions of Notes with a Conversion Date that occurs on or after May 1, 2032 will be settled

using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders, the Trustee and the Conversion

Agent (if other than the Trustee) no later than the Open of Business on May 1, 2032;

(2)

subject to clause (3) below, if the Company elects a Settlement Method with respect to the Conversion of any Note whose Conversion

Date occurs before May 1, 2032, then the Company will send notice of such Settlement Method to the Holder of such Note, the Trustee and

the Conversion Agent (if other than the Trustee) no later than the Close of Business on the Business Day immediately after such Conversion

Date;

(3)

if any Notes are called for Redemption, then (a) the Company will specify, in the related Redemption Notice (and, in the case of a Redemption

of fewer than all outstanding Notes, in a notice simultaneously sent to all Holders of Notes not called for Redemption) sent pursuant

to Section 4.03(F), the Settlement Method that will apply to all Conversions of Notes with a Conversion Date that occurs on or

after the related Redemption Notice Date and on or before the Business Day immediately before the related Redemption Date; and (b) if

such Redemption Date occurs on or after May 1, 2032, then such Settlement Method must be the same Settlement Method that, pursuant to

clause (1) above, applies to all Conversions of Notes with a Conversion Date that occurs on or after May 1, 2032;

(4)

the Company will use the same Settlement Method for all Conversions of Notes with the same Conversion Date (and, for the avoidance of

doubt, the Company will not be obligated to use the same Settlement Method with respect to Conversions of Notes with different Conversion

Dates, except as provided in clause (1) or (3) above);

-33-

(5)

if the Company does not timely elect a Settlement Method with respect to the Conversion of a Note, then the Company will be deemed to

have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute

a Default or Event of Default); and

(6)

if the Company timely elects Combination Settlement with respect to the Conversion of a Note but does not timely notify the Holder of

such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such Conversion will be deemed to be $1,000

per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such notification will not constitute

a Default or Event of Default).

At or before the time the Company sends any notice referred to in this Section 5.03(A)(i), the

Company will send a copy of such notice to the Trustee and the Conversion Agent (if other than the Trustee), but the failure to timely

send such copy will not affect the validity of any Settlement Method election.

(ii)

The Company’s Right to Irrevocably Fix or Eliminate Settlement Methods. The Company will have the right, exercisable at

its election by sending notice of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent (if other than the

Trustee)), to (1) irrevocably fix the Settlement Method that will apply to all Conversions of Notes with a Conversion Date that occurs

on or after the date such notice is sent to Holders; or (2) irrevocably eliminate any one or more (but not all) Settlement Methods (including

eliminating Combination Settlement with a particular Specified Dollar Amount or range of Specified Dollar Amounts) with respect to all

Conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders, provided, in each

case, that (w) the Settlement Method so elected pursuant to clause (1) above, or the Settlement Method(s) remaining after any

elimination pursuant to clause (2) above, as applicable, must be a Settlement Method or Settlement Method(s), as applicable, that

the Company is then permitted to elect (for the avoidance of doubt, including pursuant to, and subject to, the other provisions of this

Section 5.03(A)); (x) no such irrevocable election or Default Settlement Method change will affect any Settlement Method theretofore

elected (or deemed to be elected) with respect to any Note pursuant to the Indenture (including pursuant to Section 8.01(G) or

this Section 5.03(A)); (y) upon any such irrevocable election pursuant to clause (1) above, the Default Settlement Method

will automatically be deemed to be set to the Settlement Method so fixed; and (z) upon any such irrevocable election pursuant to clause

(2) above, the Company will, if needed, simultaneously change the Default Settlement Method to a Settlement Method that is consistent

with such irrevocable election. Such notice, if sent, must set forth the applicable Settlement Method(s) so elected or eliminated, as

applicable, and the Default Settlement Method applicable immediately after such election, and expressly state that the election is irrevocable

and applicable to all Conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders. For

the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the Indenture or the Notes,

including pursuant to Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an

amendment at its option).

(iii)

Requirement to Publicly Disclose the Fixed or Default Settlement Method. If the Company changes the Default Settlement Method

pursuant to clause (x) of the proviso to the definition of such term or irrevocably fixes the Settlement Method(s) pursuant to

Section 5.03(A)(ii), then the Company will, substantially concurrently, either post the Default Settlement Method or fixed Settlement

Method(s), as applicable, on its website or disclose the same in a Current Report on Form 8-K (or any successor form) that is filed with,

or furnished to, the SEC.

-34-

(B)

Conversion Consideration.

(i)

Generally. Subject to Sections 5.03(B)(ii), 5.03(B)(iii) and 5.09(A)(2), the type and amount of consideration

(the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be Converted will be

as follows:

(1)

if Physical Settlement applies to such Conversion, subject to Section 5.03(B)(ii), a number of shares of Common Stock equal to

the Conversion Rate in effect on the Conversion Date for such Conversion;

(2)

if Cash Settlement applies to such Conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading

Day in the Observation Period for such Conversion; or

(3)

if Combination Settlement applies to such Conversion, consideration consisting, subject to Section 5.03(B)(ii), of (a) a number

of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such Conversion;

and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

(ii)

Cash in Lieu of Fractional Shares. If Physical Settlement or Combination Settlement applies to the Conversion of any Note and

the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such Conversion is not a whole number, then

such number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other consideration due

upon such Conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) (x)

the Daily VWAP on the Conversion Date for such Conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding

VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the last VWAP Trading Day of the Observation Period for

such Conversion, in the case of Combination Settlement.

(iii)

Conversion of Multiple Notes by a Single Holder. If a Holder Converts more than one (1) Note on a single Conversion Date, then

the Conversion Consideration due in respect of such Conversion will (in the case of any Global Note, to the extent permitted by, and

practicable under, the Depositary Procedures) be computed based on the total principal amount of Notes Converted on such Conversion Date

by such Holder.

(iv)

Notice of Calculation of Conversion Consideration. If Cash Settlement or Combination Settlement applies to the Conversion of any

Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the

applicable Observation Period and will promptly thereafter send notice to the Trustee and the Conversion Agent of the same and the calculation

thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination.

(C)

Delivery of the Conversion Consideration. Except as set forth in Sections 5.05(D) and 5.09, the Company will pay

or deliver, as applicable, the Conversion Consideration due upon the Conversion of any Note to the Holder as follows: (i) if Cash Settlement

or Combination Settlement applies to such Conversion, on or before the second (2nd) Business Day immediately after the last VWAP Trading

Day of the Observation Period for such Conversion; and (ii) if Physical Settlement applies to such Conversion, on or before the second

(2nd) Business Day immediately after the Conversion Date for such Conversion; provided, however, that if (1) any Note is

Converted with a Conversion Date occurring after the Regular Record Date immediately preceding the Maturity Date; and (2) Physical Settlement

applies to such Conversion, then (x) the Company will settle such Conversion on the Maturity Date (or, if the Maturity Date is not a

Business Day, the next Business Day), as applicable; and (y) the Conversion Date will instead be deemed to be the Scheduled Trading Day

immediately before the Maturity Date.

-35-

(D)

Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a Holder Converts a Note,

then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided

in Section 5.02(D), the Company’s delivery of the Conversion Consideration due in respect of such Conversion will be deemed

to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest on, such Note

to, but excluding the relevant Conversion Date. As a result, except as provided in Section 5.02(D), any accrued and unpaid interest

on a Converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. In addition, subject to Section

5.02(D), upon Conversion, accrued and unpaid interest is first paid by any cash paid upon such Conversion (other than cash paid in

lieu of a fractional share) and thereafter by shares of Common Stock.

Section

5.04 Reserve and Status of Common Stock Issued Upon Conversion.

(A)

Stock Reserve. At all times when any Notes are outstanding, the Company will reserve (out of its authorized and not outstanding

shares of Common Stock that are not reserved for other purposes) a number of shares of Common Stock equal to the product of (i) the aggregate

principal amount (expressed in thousands) of all then-outstanding Notes; and (ii) the Conversion Rate then in effect (assuming, for these

purposes, that Physical Settlement will apply to such Conversion and the Conversion Rate is increased by the maximum amount pursuant

to which the Conversion Rate may be increased pursuant to Section 5.07). To the extent the Company delivers shares of Common Stock

held in its treasury in settlement of the Conversion of any Notes, each reference in the Indenture or the Notes to the issuance of shares

of Common Stock in connection therewith will be deemed to include such delivery, mutatis mutandis.

(B)

Status of Conversion Shares; Listing. Each Conversion Share, if any, delivered upon Conversion of any Note will be a newly issued

or treasury share (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need

not be a newly issued or treasury share) and will be duly authorized, validly issued, fully paid, non-assessable, free from preemptive

rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of

the Holder of such Note or the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities

exchange, or quoted on any inter-dealer quotation system, then the Company will use commercially reasonable efforts to cause each Conversion

Share, when delivered upon Conversion of any Note, to be admitted for listing on such exchange or quotation on such system.

Section

5.05 Adjustments to the Conversion Rate.

(A)

Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from time to time as follows:

(i)

Stock Dividends, Splits and Combinations. If the Company issues solely shares of Common Stock as a dividend or distribution on

all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock

(in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply), then

the Conversion Rate will be adjusted based on the following formula:

-36-

where:

CR0

=

the

Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately

before the Open of Business on the Effective Date of such stock split or stock combination, as applicable;

CR1

=

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 before the Open of Business on such Ex-Dividend Date or Effective Date, as

applicable, without giving effect to such dividend, distribution, stock split or stock combination; and

OS1

=

the

number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.

If

any dividend, distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is declared or announced,

but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not

to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in

effect had such dividend, distribution, stock split or stock combination not been declared or announced.

(ii)

Rights, Options and Warrants. If the Company distributes, to all or substantially all holders of Common Stock, rights, options

or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which Sections 5.05(A)(iii)(1)

and 5.05(F) will apply) entitling such holders, for a period of not more than sixty (60) calendar days after the record date

of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last

Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately

before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:

-37-

where:

CR0

=

the

Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

CR1

=

the

Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

OS

=

the

number of shares of Common Stock outstanding immediately before 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

=

a

number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants

by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on,

and including, the Trading Day immediately before the date such distribution is announced.

To

the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that

would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of only the rights, options

or warrants, if any, actually distributed. In addition, to the extent that shares of Common Stock are not delivered after the expiration

of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate

will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution

been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, options

or warrants.

For

purposes of this Section 5.05(A)(ii), in determining whether any rights, options or warrants entitle holders of Common Stock to

subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices

per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the

date the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such

rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants

and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Company in good

faith and in a commercially reasonable manner.

(iii)

Spin-Offs and Other Distributed Property.

(1)

Distributions Other than Spin-Offs. If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other

assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all

or substantially all holders of the Common Stock, excluding:

(a)

dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required (or would be required

without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i)) or 5.05(A)(ii);

(b)

dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required (or would be required

without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv);

-38-

(c)

rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(F);

(d)

Spin-Offs for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C))

pursuant to Section 5.05(A)(iii)(2);

(e)

a distribution solely pursuant to a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will

apply; and

(f)

a distribution solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply,

then

the Conversion Rate will be increased based on the following formula:

where:

CR0

=

the

Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

CR1

=

the

Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

SP

=

the

average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including,

the Trading Day immediately before such Ex-Dividend Date; and

FMV

=

the

fair market value (as determined by the Company in good faith and in a commercially reasonable manner), as of such Ex-Dividend Date,

of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed per share of Common

Stock pursuant to such distribution;

provided,

however, that if FMV is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion

Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution,

at the same time and on the same terms as holders of Common Stock, and without having to Convert its Notes, the amount and kind of shares

of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received in such

distribution if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect

on such record date.

To

the extent such distribution is not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be

in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid.

-39-

(2)

Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interests,

of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common

Stock (other than solely pursuant to (x) a Common Stock Change Event, as to which Section 5.09 will apply; or (y) a tender offer

or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), and such Capital Stock or equity interests

are listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a

“Spin-Off”), then the Conversion Rate will be increased based on the following formula:

where:

CR0

=

the

Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Spin-Off Valuation Period for such

Spin-Off;

CR1

=

the

Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Spin-Off Valuation Period;

FMV

=

the

product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests distributed

in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off Valuation Period”) beginning on,

and including, the Ex-Dividend Date for such Spin-Off (such average to be determined as if references to Common Stock in the definitions

of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such Capital Stock or equity interests);

and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off;

and

SP

=

the

average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.

Notwithstanding

anything to the contrary in this Section 5.05(A)(iii)(2), (i) if any VWAP Trading Day of the Observation Period for a Note whose

Conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs during the Spin-Off Valuation Period for such

Spin-Off, then, solely for purposes of determining the Conversion Rate for such VWAP Trading Day for such Conversion, such Spin-Off Valuation

Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off

to, and including, such VWAP Trading Day; and (ii) if the Conversion Date for a Note whose Conversion will be settled pursuant to Physical

Settlement occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Consideration

due in respect of such Conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the period

from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such Conversion Date.

To

the extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid,

the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis

of only the dividend or distribution, if any, actually made or paid.

-40-

(iv)

Cash Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common Stock,

then the Conversion Rate will be increased based on the following formula:

where:

CR0

= the

Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution;

CR1

= the

Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date for such dividend or distribution;

SP

= the

Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend

Date for such dividend or distribution; and

D

=

the

cash amount distributed per share of Common Stock in such dividend or distribution;

provided,

however, that if D is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate,

each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution,

at the same time and on the same terms as holders of Common Stock, and without having to Convert its Notes, the amount of cash that such

Holder would have received in such dividend or distribution if such Holder had owned, on such record date, a number of shares of Common

Stock equal to the Conversion Rate in effect on such record date.

To

the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate

that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or

paid.

(v)

Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange

offer for shares of Common Stock (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange

Act), and the value (determined as of the Expiration Time by the Company in good faith and in a commercially reasonable manner) of the

cash and other consideration paid or payable per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale

Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which

tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased

based on the following formula:

-41-

where:

CR0

=

the

Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period

for such tender or exchange offer;

CR1

=

the

Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period;

AC

=

the

aggregate value (determined as of the time (the “Expiration Time”) such tender or exchange offer expires by the

Company in good faith and in a commercially reasonable manner) of all cash and other consideration paid or payable for shares of Common

Stock purchased or exchanged in such tender or exchange offer;

OS0

=

the

number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted

for purchase or exchange in such tender or exchange offer);

OS1

=

the

number of shares of Common Stock outstanding immediately after the Expiration Time (excluding 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 per share of Common Stock over the ten (10) consecutive Trading Day period (the “Tender/Exchange

Offer Valuation Period”) beginning on, and including, the Trading Day immediately after the Expiration Date;

provided,

however, that the Conversion Rate will in no event be adjusted down pursuant to this Section 5.05(A)(v), except to the

extent provided in the immediately following paragraph. Notwithstanding anything to the contrary in this Section 5.05(A)(v), if

(i) any VWAP Trading Day of the Observation Period for a Note whose Conversion will be settled pursuant to Cash Settlement or Combination

Settlement occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of determining

the Conversion Rate for such VWAP Trading Day for such Conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist

of the Trading Days occurring in the period from, and including, the Trading Day immediately after the Expiration Date for such tender

or exchange offer to, and including, such VWAP Trading Day and (ii) if the Conversion Date for a Note whose Conversion will be settled

pursuant to Physical Settlement occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely

for purposes of determining the Conversion Consideration due in respect of such Conversion, such Tender/Exchange Offer Valuation Period

will be deemed to consist of the Trading Days occurring in the period from, and including, the Trading Day immediately after the Expiration

Date to, and including, such Conversion Date.

To

the extent such tender or exchange offer is announced but not consummated (including as a result of being precluded from consummating

such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange

offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been

made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender

or exchange offer.

-42-

(B)

No Adjustments in Certain Cases.

(i)

Where Holders Participate in the Transaction or Event Without Conversion. Notwithstanding anything to the contrary in Section

5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring

an adjustment pursuant to Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i)

or a tender or exchange offer of the type set forth in Section 5.05(A)(v)) if each Holder participates, at the same time and

on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having

to Convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion

Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder

on such date.

(ii)

Certain Events. The Company will not be required to adjust the Conversion Rate except as provided in Section 5.05 or Section

5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account of:

(1)

except as otherwise provided in Section 5.05, the sale of shares of Common Stock for a purchase price that is less than the market

price per share of Common Stock or less than the Conversion Price;

(2)

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 such

plan;

(3)

the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future

employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries;

(4)

the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the Company

outstanding as of the Issue Date;

(5)

solely a change in the par value of the Common Stock; or

(6)

accrued and unpaid interest on the Notes.

(C)

Adjustment Deferral. If an adjustment to the Conversion Rate otherwise required by this Article 5 would result in a change

of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company

may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately

upon the earliest of the following: (i) when all such deferred adjustments would, had they not been so deferred and carried forward,

result in a change of at least one percent (1%) to the Conversion Rate; (ii) the Conversion Date of any Note (in the case of Physical

Settlement), or each VWAP Trading Day of an Observation Period for any Note (in the case of Cash Settlement or Combination Settlement);

(iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; (iv) the date the Company calls any Notes for Redemption;

and (v) May 1, 2032.

(D)

Adjustments Not Yet Effective. Notwithstanding anything to the contrary in the Indenture or the Notes, if:

(i)

a Note is to be Converted and Physical Settlement or Combination Settlement applies to such Conversion;

-43-

(ii)

the record date, Effective Date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to Section

5.05(A) has occurred on or before the Conversion Date for such Conversion (in the case of Physical Settlement) or on or before any

VWAP Trading Day in the Observation Period for such Conversion (in the case of Combination Settlement), but an adjustment to the Conversion

Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

(iii)

the Conversion Consideration due upon such Conversion includes whole shares of Common Stock (in the case of Physical Settlement) or due

in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement);

and

(iv)

such shares are not entitled to participate in such event (because they were not held on the related record date or otherwise), then,

solely for purposes of such Conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date

(in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which

the Company is otherwise required to deliver the consideration due upon such Conversion is before the first date on which the amount

of such adjustment can be determined, then the Company will delay the settlement of such Conversion until the second (2nd) Business Day

after such first date.

(E)

Conversion Rate Adjustments Where Converting Holders Participate in the Relevant Transaction or Event. Notwithstanding anything

to the contrary in the Indenture or the Notes, if:

(i)

a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A);

(ii)

a Note is to be Converted pursuant to Physical Settlement or Combination Settlement;

(iii)

the Conversion Date for such Conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation Period for such

Conversion (in the case of Combination Settlement) occurs on or after such Ex-Dividend Date and on or before the related record date;

(iv)

the Conversion Consideration due upon such Conversion includes any whole shares of Common Stock (in the case of Physical Settlement)

or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement),

in each case based on a Conversion Rate that is adjusted for such dividend or distribution; and

(v)

such shares would be entitled to participate in such dividend or distribution (including pursuant to Section 5.02(C)),

then:

(x)

in the case of Physical Settlement, such Conversion Rate adjustment will not be given effect for such Conversion and the shares of Common

Stock issuable upon such Conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or

distribution, but there will be added, to the Conversion Consideration otherwise due upon such Conversion, the same kind and amount of

consideration that would have been delivered in such dividend or distribution with respect to such shares of Common Stock had such shares

been entitled to participate in such dividend or distribution; and

-44-

(y)

in the case of Combination Settlement, the Conversion Rate adjustment relating to such Ex-Dividend Date will be made for such Conversion

in respect of such VWAP Trading Day, but the shares of Common Stock issuable with respect to such VWAP Trading Day based on such adjusted

Conversion Rate will not be entitled to participate in such dividend or distribution.

(F)

Stockholder Rights Plans. If any shares of Common Stock are to be issued upon Conversion of any Note and, at the time of such

Conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition

to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under the Indenture upon such Conversion, the

rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case,

and only in such case, the Conversion Rate will be adjusted pursuant to Section 5.05(A)(iii)(1) on account of such separation

as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of

the Common Stock, subject to potential readjustment in accordance with the last paragraph of Section 5.05(A)(iii)(1).

(G)

Limitation on Effecting Transactions Resulting in Certain Adjustments. The Company will not engage in or be a party to any transaction

or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07 to an amount

that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock.

(H)

Equitable Adjustments to Prices. Whenever any provision of the Indenture requires the Company to calculate the average of the

Last Reported Sale Prices, or any function thereof, the Daily VWAPs, the Daily Conversion Values, the Daily Cash Amounts or the Daily

Share Amounts over a period of multiple days (including over an Observation Period, to calculate an adjustment to the Conversion Rate

and the period, if any, for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Company will, acting in

good faith and in a commercially reasonable manner, make appropriate adjustments, if any, to those calculations 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 applicable, of the event occurs, at any time during such period or Observation Period, as applicable.

(I)

Calculation of Number of Outstanding Shares of Common Stock. For purposes of Section 5.05(A), the number of shares of Common

Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares

of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or

makes any distribution on shares of Common Stock held in its treasury).

(J)

Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th

of a share of Common Stock (with 5/100,000ths rounded upward) or to the nearest cent (with 0.5 of a cent rounded upward), as applicable.

(K)

Notice of Conversion Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section

5.05(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent (if other than the Trustee) containing

(i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate in effect

immediately after such adjustment; and (iii) the effective time of such adjustment.

-45-

Section

5.06 Voluntary Adjustments.

(A)

Generally. To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not

required to) increase the Conversion Rate by any amount if (x)the Board of Directors determines that such increase is either (x) in the

best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock or rights to purchase

Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event;

(ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such

period.

(B)

Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to Section 5.06(A),

then, no later than the first Business Day of the related twenty (20) or more Business Day period referred to in Section 5.06(A),

the Company will send notice to each Holder, the Trustee and the Conversion Agent of such increase, the amount thereof and the period

during which such increase will be in effect.

Section

5.07 Adjustments to the Conversion Rate in Connection with a Make-Whole Fundamental Change.

(A)

Generally. If a Make-Whole Fundamental Change occurs and the Conversion Date for the Conversion of a Note occurs during the related

Make-Whole Fundamental Change Conversion Period, then, subject to this Section 5.07, the Conversion Rate applicable to such Conversion

will be increased by a number of shares (the “Additional Shares”) set forth in the table below corresponding (after

interpolation as provided in, and subject to, the provisions below) to the Make-Whole Fundamental Change Effective Date and the Stock

Price of such Make-Whole Fundamental Change:

If

such Make-Whole Fundamental Change Effective Date or Stock Price is not set forth in the table above, then:

(i)

if such Stock Price is between two Stock Prices in the table above or the Make-Whole Fundamental Change Effective Date is between two

dates in the table above, then the number of Additional Shares will be determined by straight-line interpolation between the numbers

of Additional Shares set forth for the higher and lower Stock Prices in the table above or the earlier and later dates in the table above,

based on a 365- or 366-day year, as applicable; and

(ii)

if the Stock Price is greater than $825.00 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings

of the table above are adjusted pursuant to Section 5.07(B)), or less than $88.95 (subject to adjustment in the same manner),

per share of Common Stock, then no Additional Shares of Common Stock will be added to the Conversion Rate.

-46-

Notwithstanding

anything to the contrary in the Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 11.2422

shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the

same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to Section 5.05(A).

For

the avoidance of doubt, but subject to Section 4.03(I), (x) the sending of a Redemption Notice will constitute a Make-Whole Fundamental

Change only with respect to the Notes called (or deemed called) for Redemption pursuant to such Redemption Notice, and not with respect

to any other Notes; and (y) the Conversion Rate applicable to the Notes not so called (or deemed called) for Redemption will not be subject

to increase pursuant to this Section 5.07 on account of such Redemption Notice.

(B)

Adjustment of Stock Prices and Number of Additional Shares. The Stock Prices in the first row (i.e., the column headers)

of the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the same events

for which, the Conversion Price is adjusted as a result of the operation of Section 5.05(A). The adjusted Stock Prices will equal

the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately

prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted.

The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the

same time and for the same events for which, the Conversion Rate is adjusted pursuant to Section 5.05(A).

(C)

Notice of the Occurrence of a Make-Whole Fundamental Change. If a Make-Whole Fundamental Change occurs pursuant to clause (A)

of the definition thereof, then, promptly and in no event later than the second Business Day immediately after the Make-Whole Fundamental

Change Effective Date of such Make-Whole Fundamental Change, the Company will notify the Holders of the occurrence of such Make-Whole

Fundamental Change and of such Make-Whole Fundamental Change Effective Date, briefly stating the circumstances under which the Conversion

Rate will be increased pursuant to this Section 5.07 in connection with such Make-Whole Fundamental Change. The Company will notify

the Holders of each Make-Whole Fundamental Change occurring pursuant to clause (B) of the definition thereof in the related Optional

Redemption Notice in accordance with Section 4.03(F) (with a copy to the Trustee and the Conversion Agent, if other than the Trustee).

(D)

Settlement of Cash Make-Whole Fundamental Changes. For the avoidance of doubt, if holders of Common Stock receive solely cash

in a Make-Whole Fundamental Change, then, pursuant to Section 5.09, Conversions of Notes will thereafter be settled no later than

the second (2nd) Business Day after the relevant Conversion Date.

Section

5.08 Exchange in Lieu of Conversion.

Notwithstanding

anything to the contrary in this Article 5, and subject to the terms of this Section 5.08, if a Note is submitted for Conversion,

the Company may elect to arrange to have such Note exchanged in lieu of Conversion by a financial institution designated by the Company.

To make such election, the Company must send notice of such election to the Holder of such Note, the Trustee and the Conversion Agent

(if other than the Trustee) before the Close of Business on the Business Day immediately following the Conversion Date for such Note.

If the Company has made such election, then:

(A)

no later than the Business Day immediately following such Conversion Date, the Company must deliver (or cause the Conversion Agent to

deliver) such Note, together with delivery instructions for the Conversion Consideration due upon such Conversion (including wire instructions,

if applicable), to a financial institution designated by the Company that has agreed to deliver such Conversion Consideration in the

manner and at the time the Company would have had to deliver the same pursuant to this Article 5;

-47-

(B)

if such Note is a Global Note, then (i) such designated institution will send written confirmation to the Conversion Agent promptly after

wiring the cash Conversion Consideration, if any, and delivering any other Conversion Consideration, due upon such Conversion to the

Holder of such Note; and (ii) the Conversion Agent will as soon as reasonably practicable thereafter contact such Holder’s custodian

with the Depositary to confirm receipt of the same; and

(C)

such Note will not cease to be outstanding by reason of such exchange in lieu of Conversion;

provided, however, that if

such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration, then the Company will

be responsible for delivering such Conversion Consideration in the manner and at the time provided in this Article 5 as if the

Company had not elected to make an exchange in lieu of Conversion.

Section

5.09 Effect of Common Stock Change Event.

(A)

Generally. If there occurs any:

(i)

recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or combination

of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value and (z) stock splits

and stock combinations that do not involve the issuance of any other series or class of securities);

(ii)

consolidation, merger, combination or binding or statutory share exchange involving the Company;

(iii)

sale, lease or other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any

Person; or

(iv)

other similar event,

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right

to receive, other securities, cash or other property, or any combination of the foregoing (such an event, a “Common Stock Change

Event,” and such other securities, cash or property, the “Reference Property,” and the amount and kind of

Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change

Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a “Reference

Property Unit”), then, notwithstanding anything to the contrary in the Indenture or the Notes,

(1)

from and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon Conversion of any Note,

and the conditions to any such Conversion, will be determined in the same manner as if each reference to any number of shares of Common

Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of Reference Property Units;

(II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in such Section (or in any related definitions)

will instead be deemed to be a reference to the same number of Reference Property Units; and (III) for purposes of the definitions of

“Fundamental Change” and “Make-Whole Fundamental Change,” references to “Common Stock” and the Company’s

“Common Equity” will be deemed to refer to the Common Equity (including depositary receipts representing Common Equity),

if any, forming part of such Reference Property;

-48-

(2)

if such Reference Property Unit consists entirely of cash, then (I) each Conversion of any Note with a Conversion Date that occurs on

or after the effective date of such Common Stock Change Event will be settled entirely in cash in an amount, per $1,000 principal amount

of such Note being Converted, equal to the product of (x) the Conversion Rate in effect on such Conversion Date (including, for the avoidance

of doubt, any increase to such Conversion Rate pursuant to Section 5.07, if applicable); and (y) the amount of cash constituting

such Reference Property Unit; and (II) the Company will settle each such Conversion no later than the second (2nd) Business Day after

the relevant Conversion Date; and

(3)

for these purposes, (I) the Daily VWAP of any Reference Property Unit or portion thereof that consists of a class of Common Equity securities

will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg page for such

class of securities in such definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof that does not consist

of a class of Common Equity securities, and the Last Reported Sale Price of any Reference Property Unit or portion thereof that does

not consist of a class of securities, will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined

in good faith and in a commercially reasonable manner by the Company (or, in the case of cash denominated in U.S. dollars, the face amount

thereof).

If

the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder

election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration

actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify Holders, the Trustee and the Conversion

Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

At

or before the effective time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not

the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a

supplemental indenture pursuant to Section 8.01(F), which supplemental indenture will (x) provide for subsequent Conversions of

Notes in the manner set forth in this Section 5.09; (y) provide for subsequent adjustments to the Conversion Rate pursuant to

Section 5.05(A) in a manner consistent with this Section 5.09; and (z) contain such other provisions, if any, that the

Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions

of this Section 5.09(A). If the Reference Property includes shares of stock or other securities or assets (other than cash) of

a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental

indenture will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve the economic

interests of the Holders.

(B)

Notice of Common Stock Change Events. The Company will provide notice of each Common Stock Change Event to Holders, the Trustee

and the Conversion Agent (if other than the Trustee) no later than the second (2nd) Business Day after the effective date of such Common

Stock Change Event, including a brief description of such Common Stock Change Event, its effective date and a brief description of the

anticipated change in the Conversion right of the Notes.

(C)

Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent with

this Section 5.09.

the effective time of any Business Combination Event that complies with Section 6.01, the Successor Entity (if not the Company)

will succeed to, and may exercise every right and power of, the Company under the Indenture and the Notes with the same effect as if

such Successor Entity had been named as the Company in the Indenture and the Notes, and, except in the case of a lease, the predecessor

Company will be discharged from its obligations under the Indenture and the Notes.

Section

7.01 Events of Default.

(A)

Definition of Events of Default. “Event of Default” means the occurrence of any of the following:

(i)

a default in the payment when due (whether at maturity, upon Redemption or Repurchase Upon Fundamental Change or otherwise) of the principal

of, or the Redemption Price or Fundamental Change Repurchase Price for, any Note;

(ii)

a default for thirty (30) consecutive days in the payment when due of interest on any Note;

(iii)

the Company’s failure to deliver, when required by the Indenture, a Fundamental Change Notice, or a notice pursuant to Section

5.01(C)(i)(3), if (in the case of any notice other than a notice pursuant to Section 5.01(C)(i)(3)(a)), such failure is not

cured within three (3) Business Days after its occurrence (or, in the case of a notice pursuant to Section 5.01(C)(i)(3)(a), when

due);

(iv)

a default in the Company’s obligation to Convert a Note in accordance with Article 5 upon the exercise of the Conversion

right with respect thereto, if such default is not cured within three (3) Business Days after its occurrence;

(v)

a default in the Company’s obligations under Article 6;

(vi)

a default in any of the Company’s obligations or agreements under the Indenture or the Notes (other than a default set forth in

clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where such default is not cured

or waived within sixty (60) days after notice to the Company by the Trustee, or to the Company and the Trustee by Holders of at least

twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand

that it be remedied and state that such notice is a “Notice of Default”;

(vii)

a default by the Company or any of the Company’s Significant Subsidiaries with respect to any one or more mortgages, agreements

or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed

of at least sixty million dollars ($60,000,000) (or its foreign currency equivalent) in the aggregate of the Company or any of the Company’s

Significant Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default:

(1)

constitutes a failure to pay the principal of such indebtedness when due and payable at its stated maturity, upon required repurchase,

upon declaration of acceleration or otherwise, in each case after the expiration of any applicable grace period; or

(2)

results in such indebtedness becoming or being declared due and payable before its stated maturity,

in each case where such default is

not cured or waived within thirty (30) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of

at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding;

(viii)

a final judgment being rendered against the Company or any of its Significant Subsidiaries for the payment of at least sixty million

dollars ($60,000,000) (or its foreign currency equivalent) (excluding any amounts covered by insurance), where such judgment is not discharged

or stayed within sixty (60) days after (i) the date on which the right to appeal the same has expired, if no such appeal has commenced;

or (ii) the date on which all rights to appeal have been extinguished;

-51-

(ix)

the Company or any of its Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either:

(1)

commences a voluntary case or proceeding;

(2)

consents to the entry of an order for relief against it in an involuntary case or proceeding;

(3)

consents to the appointment of a custodian of it or for any substantial part of its property;

(4)

makes a general assignment for the benefit of its creditors;

(5)

takes any comparable action under any foreign Bankruptcy Law; or

(6)

generally is not paying its debts as they become due; or

(x)

a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that either:

(1)

is for relief against the Company or any of its Significant Subsidiaries in an involuntary case or proceeding;

(2)

appoints a custodian of the Company or any of its Significant Subsidiaries, or for any substantial part of the property of the Company

or any of its Significant Subsidiaries;

(3)

orders the winding up or liquidation of the Company or any of its Significant Subsidiaries; or

(4)

grants any similar relief under any foreign Bankruptcy Law,

and,

in each case under this Section 7.01(A)(x), such order or decree remains unstayed and in effect for at least sixty (60) days.

For

the avoidance of doubt, any failure by the Company to provide any notice under the Indenture other than as set forth in Section 7.01(A)(iii)

above shall be subject to Section 7.01(A)(vi) above (including the 60-day cure period contained therein).

(B)

Cause Irrelevant. Each of the events set forth in Section 7.01(A) will constitute an Event of Default regardless of the

cause thereof or whether voluntary or involuntary or 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.

Section

7.02 Acceleration.

(A)

Automatic Acceleration in Certain Circumstances. If an Event of Default set forth in Section

7.01(A)(ix) or 7.01(A)(x) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the

Company), then the principal amount of, and all accrued and unpaid interest, if any, on, all of the Notes then outstanding will immediately

become due and payable without any further action or notice by any Person.

-52-

(B)

Optional Acceleration. Subject to Section 7.03, if an Event of Default (other than an Event of Default set forth in Section

7.01(A)(ix) or 7.01(A)(x) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company)

occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate

principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued

and unpaid interest, if any, on, all of the Notes then outstanding to become due and payable immediately. For the avoidance of doubt,

if such Event of Default is not continuing at the time such notice is provided (that is, such Event of Default has been cured or waived

as of such time), then such notice will not be effective to cause such amounts to become due and payable immediately.

(C)

Rescission of Acceleration. Notwithstanding anything to the contrary in the Indenture or the Notes, the Holders of a majority

in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders,

rescind any acceleration of the Notes and its consequences if (i) such rescission would not conflict with any judgment or decree of a

court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest, if any,

on, the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect any

subsequent Default or impair any right consequent thereto.

Section

7.03 Sole Remedy for a Failure to Report.

(A)

Generally. Notwithstanding anything to the contrary in the Indenture or the Notes, the Company may elect that the sole remedy

for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the

Company’s failure to comply with Section 3.02 (including the Company’s obligations under Section 314(a)(1) of the

Trust Indenture Act) will, for each of the first three hundred and sixty five (365) calendar days on which such Reporting Event of Default

has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an

election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant Reporting Event

of Default from, and including, the three hundred and sixty-sixth (366th) calendar day on which such Reporting Event of Default has occurred

and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease

to accrue on any Notes from, and including, such three hundred sixty-sixth (366th) calendar day (it being understood that interest on

any defaulted Special Interest will nonetheless accrue pursuant to Section 2.04(B)).

(B)

Amount and Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to Section 7.03(A) will accrue

at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first one hundred and eighty

(180) days on which such Reporting Event of Default is continuing and Special Interest accrues and, thereafter, at a rate per annum equal

to one half of one percent (0.50%) of the principal amount thereof, to, and including, the three hundred and sixty-fifth (365th) calendar

day on which such Reporting Event of Default is continuing and Special Interest accrues. For the avoidance of doubt, any Special Interest

that accrues on a Note will be in addition to the Stated Interest that accrues on such Note.

(C)

Notice of Election. To make the election set forth in Section 7.03(A), the Company must send to the Holders, the Trustee

and the Paying Agent (if other than the Trustee), before the date on which each Reporting Event of Default first occurs, a notice that

(i) briefly describes the report(s) that the Company failed to file with the SEC; (ii) states that the Company is electing that the sole

remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the periods during

which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account

of such Reporting Event of Default.

-53-

(D)

Notice to Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest accrues on any Note, then, no later than five

(5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s Certificate

to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Special Interest on such Note on such date of payment;

and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee will have no duty to determine whether

any Special Interest is payable or the amount thereof.

(E)

No Effect on Other Events of Default. No election pursuant to this Section 7.03 with respect to a Reporting Event of Default

will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event

of Default.

Section

7.04 Other Remedies.

(A)

Trustee May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue any available remedy

to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of the Indenture or

the Notes.

(B)

Procedural Matters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any

of them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of

Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of Default. All remedies will be

cumulative to the extent permitted by law.

Section

7.05 Waiver of Past Defaults.

An

Event of Default pursuant to clause (i), (ii), (iv) or (vi) of Section 7.01(A) (that, in the case

of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder),

and a Default that could lead to such an Event of Default, can be waived only with the consent of each affected Holder. Each other Default

or Event of Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal amount of the Notes

then outstanding. If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed

to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent

or other Default or Event of Default or impair any right arising therefrom.

Section

7.06 Cure of Defaults; Ability to Cure or Waive Before Event of Default Occurs.

For

the avoidance of doubt, and without limiting the manner in which any Default can be cured, (A) a Default or Event of Default consisting

of a failure to send a notice in accordance with the Indenture will be cured upon the sending of such notice; (B) a Default or Event

of Default in making any payment on (or delivering any other consideration in respect of) any Note will be cured upon the delivery, in

accordance with the Indenture, of such payment (or other consideration) together, if applicable, with Default Interest thereon; and (C)

a Default or Event of Default that is (or, after notice, passage of time or both, would be) a Reporting Event of Default will be cured

upon the filing of the relevant report(s) giving rise to such Reporting Event of Default; provided that (i) 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 (ii) the cure of any Reporting Event of Default shall not affect the Company’s

obligation to pay any Special Interest that accrues prior to the time of such cure. In addition, for the avoidance of doubt, if a Default

that is not an Event of Default is cured or waived before such Default would have constituted an Event of Default, then no Event of Default

will result from such Default.

-54-

Section

7.07 Control by Majority.

Holders

of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding

for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse

to follow any direction that conflicts with law, the Indenture or the Notes, or that, subject to Section 7.01 of the Base Indenture,

the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee

is offered (and, if requested, provided with) security and indemnity satisfactory to the Trustee against any loss, liability or expense

to the Trustee that may result from the Trustee’s following such direction.

Section

7.08 Limitation on Suits.

No

Holder may pursue any remedy with respect to the Indenture or the Notes (except to enforce (x) its rights to receive the principal of,

or the Fundamental Change Repurchase Price or Redemption Price for, or interest on, any Notes; or (y) the Company’s obligations

to Convert any Notes pursuant to Article 5), unless:

(A)

such Holder has previously delivered to the Trustee notice that an Event of Default is continuing;

(B)

Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a written request to

the Trustee to pursue such remedy;

(C)

such Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to the Trustee against any

loss, liability or expense to the Trustee that may result from the Trustee’s following such request;

(D)

the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and such offer of security

or indemnity; and

(E)

during such sixty (60) calendar day period, Holders of a majority in aggregate principal amount of the Notes then outstanding do not

deliver to the Trustee a direction that is inconsistent with such request.

A

Holder of a Note may not use the Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another

Holder. The Trustee will have no duty to determine whether any Holder’s use of the Indenture complies with the preceding sentence.

Section

7.09 Absolute Right of Holders to Institute Suit for the Enforcement of the Right to Receive Payment

and Conversion Consideration.

Notwithstanding

anything to the contrary in the Indenture or the Notes (but without limiting Section 8.01), the right of each Holder of a Note

to receive payment or delivery, as applicable, of the principal of, or the Fundamental Change Repurchase Price or Redemption Price for,

or any interest on, or the Conversion Consideration due pursuant to Article 5 upon Conversion of, such Note on or after the respective

due dates therefor provided in the Indenture and the Notes, or to bring suit for the enforcement of any such payment or delivery on or

after such respective due dates, will not be impaired or affected without the consent of such Holder.

-55-

Section

7.10 Collection Suit by Trustee.

The

Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to clause (i), (ii) or

(iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for

the total unpaid or undelivered principal of, or Fundamental Change Repurchase Price or Redemption Price for, or any interest on, or

Conversion Consideration due pursuant to Article 5 upon Conversion of, the Notes, as applicable, and, to the extent lawful, any

Default Interest on any Defaulted Amounts, and such further amounts sufficient to cover the costs and expenses of collection, including

all amounts owed to it under Section 7.06 of the Base Indenture.

Section

7.11 Trustee May File Proofs of Claim.

The

Trustee has the right to (A) file such proofs of claim and other papers or documents as may be necessary or advisable in order to have

the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the

Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable or deliverable on any

such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents

to the making of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation,

expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant

to Section 7.06 of the Base Indenture. To the extent that the payment of any such compensation, expenses, disbursements, advances and

other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured by a lien on, and will

be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive

in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise). Nothing in the Indenture

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

arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect

of the claim of any Holder in any such proceeding.

Section

7.12 Priorities.

The

Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7:

First:

to the Trustee and its agents and attorneys for amounts due hereunder, including payment of all fees and compensation of, and all expenses

and liabilities incurred, and all advances made, by, the Trustee (in each of its capacities under the Indenture, including as Note Agent)

and the costs and expenses of collection;

Second:

to Holders for unpaid amounts or other property due on the Notes, including the principal of, or the Fundamental Change Repurchase Price

or Redemption Price for, or any interest on, or any Conversion Consideration due upon Conversion of, the Notes, ratably, and without

preference or priority of any kind, according to such amounts or other property due and payable on all of the Notes; and

Third:

to the Company or such other Person as a court of competent jurisdiction directs.

-56-

The

Trustee may fix a record date and payment date for any payment or delivery to the Holders pursuant to this Section 7.12, in which

case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record

date, to each Holder and the Trustee a notice stating such record date, such payment date and the amount of such payment or nature of

such delivery, as applicable.

Section

7.13 Undertaking for Costs.

In

any suit for the enforcement of any right or remedy under the Indenture or the Notes or in any suit against the Trustee for any action

taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking

to pay the costs of such suit; and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party

in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided,

however, that this Section 7.13 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section

7.09 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

Section

7.14 Notice of Defaults.

This

Section 7.14 will apply to the Notes in lieu of Section 7.14 of the Base Indenture, which will be deemed to be replaced with this

Section 7.14, mutatis mutandis.

If

a Default or Event of Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, then the Trustee

will send Holders a notice of such Default or Event of Default within ninety (90) days after it occurs or, if it is not actually known

to a Responsible Officer of the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes actually

known to a Responsible Officer of the Trustee; provided, however, that, except in the case of a Default or Event of Default

in the payment of the principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as it in good faith

determines that withholding such notice is in the interests of the Holders. For the avoidance of doubt, the Trustee will not be required

to deliver such notice at any time after such Default or Event of Default is cured or waived.

Article

8. AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section

8.01 and Section 8.02 will apply to the Notes in lieu of Section 9.01 and Section 9.02, respectively, of the Base Indenture,

(L)

comply with any requirement of the SEC in connection with effecting or maintaining the qualification of the Indenture or any supplemental

“Description of Notes” section and pricing term sheet referred to in Section 8.01(I).

Section

8.02 With the Consent of Holders.

(A)

Generally. Subject to Sections 8.01, 7.05 and 7.09 and the immediately following sentence, the Company and

the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or

supplement the Indenture or the Notes or waive compliance with any provision of the Indenture or the Notes. Notwithstanding anything

to the contrary in the foregoing sentence, but subject to Section 8.01, without the consent of each affected Holder, no amendment

or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may:

(i)

reduce the principal, or change the stated maturity, of any Note;

-58-

(ii)

reduce the Redemption Price or Fundamental Change Repurchase Price for any Note or change the times at which, or the circumstances under

which, the Notes may or will be redeemed or repurchased by the Company;

(iii)

reduce the rate, or extend the time for the payment, of interest on any Note;

For

the avoidance of doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this Section 8.02(A), no

amendment or supplement to the Indenture or the Notes, or waiver of any provision of the Indenture or the Notes, may change the amount

or type of consideration due on any Note (whether on an Interest Payment Date, Redemption Date, Fundamental Change Repurchase Date or

the Maturity Date or upon Conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable,

without the consent of each affected Holder.

(B)

Holders Need Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant to this Section 8.02 need

approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver.

Section

8.03 Notice of Amendments, Supplements and Waivers.

As

soon as reasonably practicable after any amendment, supplement or waiver pursuant to Section 8.01

or 8.02 becomes effective, the Company will send to the Holders

and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states the

effective date thereof. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of

such amendment, supplement or waiver.

Section

8.04 Revocation, Effect and Solicitation of Consents; Special Record Dates; ETC.

(A)

Revocation and Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver will bind (and constitute

the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting

Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited pursuant to Section 8.04(B)) any

such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or

waiver becomes effective.

-59-

(B)

Special Record Dates. The Company may, but is not required to, fix a record date for the purpose of determining the Holders entitled

to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record

date is fixed, then, notwithstanding anything to the contrary in Section 8.04(A), only Persons who are Holders as of such record

date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any

such action, regardless of whether such Persons continue to be Holders after such record date; provided, however, that

no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date.

(C)

Solicitation of Consents. For the avoidance of doubt, each reference in the Indenture or the Notes to the consent of a Holder

will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes.

(D)

Effectiveness and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8 will become effective

in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every

Holder of such Note (or such portion).

Section

8.05 Notations and Exchanges.

If

any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the

Holder of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company

on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such Note, issue,

execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.04 of the Base Indenture, a new Note

that reflects the changed terms. The failure to make any appropriate notation or issue a new Note pursuant to this Section 8.05 will

not impair or affect the validity of such amendment, supplement or waiver.

Section

8.06 Trustee to Execute Supplemental Indentures.

The

Trustee will execute and deliver any amendment or supplemental indenture authorized pursuant to this Article 8; provided,

however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental

indenture that adversely affects the Trustee’s rights, duties, liabilities or immunities. In executing any amendment or supplemental

indenture, the Trustee will be entitled to receive, and will be fully protected in relying on, an Officer’s Certificate and an

Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted

by the Indenture; and (B) in the case of the Opinion of Counsel, such amendment or supplemental indenture is valid, binding and enforceable

against the Company in accordance with its terms.

Article

9. SATISFACTION AND DISCHARGE

This

Article 9 will apply to the Notes in lieu of Article 11 of the Base Indenture, which will be deemed to be replaced with this Article

9, mutatis mutandis.

Section

9.01 Termination of Company’s Obligations.

The

Company’s obligations with respect to the Notes under the Indenture will be discharged, and the Indenture will cease to be of further

effect as to all Notes issued under the Indenture, when:

(A)

all Notes then outstanding (other than Notes replaced pursuant to Section 2.07 of the Base Indenture) have (i) been delivered to the

Trustee for cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity

Date, upon Conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;

-60-

(B)

the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion Consideration,

the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash

(or, with respect to Notes to be Converted, Conversion Consideration) sufficient to satisfy all amounts or other property due on all

Notes then outstanding (other than Notes replaced pursuant to Section 2.07 of the Base Indenture);

(C)

the Company has paid all other amounts payable by it under the Indenture; and

(D)

the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions precedent

to the discharge of the Indenture have been satisfied;

provided,

however, that Article 7 of the Base Indenture and Section 10.01 will survive such discharge and, until no Notes remain

outstanding, Section 2.08 of the Base Indenture and the obligations of the Trustee, the Paying Agent and the Conversion Agent with respect

to money or other property deposited with them will survive such discharge.

At

the Company’s request, the Trustee will acknowledge the satisfaction and discharge of the Indenture.

Section

9.02 Repayment to Company.

Subject

to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there

exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held

by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such payment or delivery

was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to

any Holder with respect to such cash, Conversion Consideration or other property, and Holders entitled to the payment or delivery of

such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company.

Section

9.03 Reinstatement.

If

the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to Section

9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains

or otherwise prohibits such application, then the discharge of the Indenture pursuant to Section 9.01 will be rescinded; provided,

however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then

the Company will be subrogated to the rights of such Holders to receive such cash or other property from the cash or other property,

if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.

Notwithstanding

anything to the contrary in the preceding paragraph, notices to the Trustee or any Note Agent must be in writing and will be deemed to

have been given upon actual receipt by the Trustee or such Note Agent, as applicable.

The

Company or the Trustee, by notice to the other, may designate additional or different addresses (including facsimile numbers and electronic

addresses) for subsequent notices or communications.

-62-

The

Trustee will not have any duty to confirm that the person sending any notice, instruction or other communication by electronic transmission

(including by e-mail, facsimile transmission, web portal or other electronic methods) is, in fact, a person authorized to do so. Electronic

signatures believed by the Trustee to comply with the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten

signatures and digital signatures provided by DocuSign, Orbit, Adobe Sign or any other digital signature provider acceptable to the Trustee)

will be deemed original signatures for all purposes. Any person that uses electronic signatures or electronic methods to send communications

to the Trustee assumes all risks arising out of such use, including the risk of the Trustee acting on an unauthorized communication and

the risk of interception or misuse by third parties. Notwithstanding anything to the contrary in this paragraph, the Trustee may, in

any instance and in its sole discretion, require that an original document bearing a manual signature be delivered to the Trustee in

lieu of, or in addition to, any such electronic communication.

All

notices and communications (other than those sent to Holders) will be deemed to have been duly given: (A) at the time delivered by hand,

if personally delivered; (B) five (5) Business Days after being deposited in the mail, postage prepaid, if mailed; (C) when receipt is

acknowledged, if transmitted by facsimile, electronic transmission or other similar means of unsecured electronic communication; and

(D) the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

All

notices or communications required to be made to a Holder pursuant to the Indenture must be made in writing and will be deemed to be

duly sent or given in writing if mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier

guaranteeing next day delivery, to its address shown on the Register; provided, however, that a notice or communication

to a Holder of a Global Note will instead be sent pursuant to the Depositary Procedures (in which case, such notice will be deemed to

be duly sent or given in writing). The failure to send a notice or communication to a Holder, or any defect in such notice or communication,

will not affect its sufficiency with respect to any other Holder.

If

the Trustee is then acting as the Depositary’s custodian for the Notes, then, at the reasonable request of the Company to the Trustee,

the Trustee will cause any notice prepared by the Company to be sent to any Holder(s) pursuant to the Depositary Procedures, provided

such request is evidenced in a Company Order delivered, together with the text of such notice, to the Trustee at least two (2) Business

Days before the date such notice is to be so sent. For the avoidance of doubt, such Company Order need not be accompanied by an Officer’s

Certificate or Opinion of Counsel. The Trustee will not have any liability relating to the contents of any notice that it sends to any

Holder pursuant to any such Company Order.

If

a notice or communication is mailed or sent in the manner provided above within the time prescribed, it will be deemed to have been duly

given, whether or not the addressee receives it.

Notwithstanding

anything to the contrary in the Indenture or the Notes, (A) whenever any provision of the Indenture requires a party to send notice to

another party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities

(and, for purposes of the interpretation of the Indenture, such notice will be deemed to have been duly sent at the time otherwise required

by the Indenture); and (B) whenever any provision of the Indenture requires a party to send notice to more than one receiving party,

and each receiving party is the same Person acting in different capacities, then only one such notice need be sent to such Person.

Section

10.02 Rules by the Trustee, the Registrar, the Paying Agent and the Conversion Agent.

The

Trustee may make reasonable rules for action by or at a meeting of Holders. Each of the Registrar, the Paying Agent and the Conversion

Agent may make reasonable rules and set reasonable requirements for its functions.

-63-

Section

10.03 No Personal Liability of Directors,

Officers, Employees and Stockholders.

No

past, present or future director, officer, employee, incorporator or stockholder of the Company, as such, will have any liability for

any obligations of the Company under the Indenture or the Notes or for any claim based on, in respect of, or by reason of, such obligations

or their creation. By accepting any Note, each Holder waives and releases all such liability. Such waiver and release are part of the

consideration for the issuance of the Notes.

Section

10.04 Governing law; waiver of jury trial.

This

Section 10.04 will, with respect to the Notes, supersede Section 13.05 of the Base Indenture in its entirety.

THE

INDENTURE AND THE NOTES, AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THE INDENTURE OR THE NOTES, WILL BE GOVERNED

BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EACH OF THE COMPANY AND THE TRUSTEE IRREVOCABLY WAIVES, TO THE

FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO

THE INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED BY THE INDENTURE OR THE NOTES.

Section

10.05 Submission to Jurisdiction.

Any

legal suit, action or proceeding arising out of or based upon the Indenture or the transactions contemplated by the Indenture may be

instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York,

in each case located in the City of New York (collectively, the “Specified Courts”), and each party irrevocably submits

to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document

by mail (to the extent allowed under any applicable statute or rule of court) to such party’s address set forth in Section 10.01

will be effective service of process for any such suit, action or proceeding brought in any such court. Each of the Company, the Trustee

and each Holder (by its acceptance of any Note) irrevocably and unconditionally waives any objection to the laying of venue of any suit,

action or other proceeding in the Specified Courts and irrevocably and unconditionally waives and agrees not to plead or claim any such

suit, action or other proceeding has been brought in an inconvenient forum.

Section

10.06 No Adverse Interpretation of Other Agreements.

Neither

the Indenture nor the Notes may be used to interpret any other indenture, note, loan or debt agreement of the Company or its Subsidiaries

or of any other Person, and no such indenture, note, loan or debt agreement may be used to interpret the Indenture or the Notes.

Section

10.07 Successors.

All

agreements of the Company in the Indenture and the Notes will bind its successors. All agreements of the Trustee in the Indenture will

bind its successors.

Any

organization or entity into which the Trustee may be merged or converted or with which it may be consolidated, or any organization or

entity resulting from any merger, conversion or consolidation to which the Trustee is a party, or any organization or entity succeeding

to all or substantially all of the corporate trust business of the Trustee, will be the successor of the Trustee under the Indenture,

without the need for the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that

such organization or entity is otherwise qualified and eligible under Section 7.09 of the Base Indenture and Section 310 of the Trust

Indenture Act.

-64-

Section

10.08 Force Majeure.

The

Trustee and each Note Agent will not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility

under the Indenture or the Notes by reason of any occurrence beyond its control (including any act or provision of any present or future

law or regulation or governmental authority, act of God or war, civil unrest, local or national disturbance or disaster, act of terrorism

or unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility).

Section

10.09 U.S.A. Patriot Act.

The

Company acknowledges that, in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial institutions, in

order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies

each person or legal entity that establishes a relationship or opens an account with the Trustee. The Company agrees to provide the Trustee

with such information as it may request to enable the Trustee to comply with the U.S.A. PATRIOT Act.

Section

10.10 Calculations.

Except

as otherwise provided in the Indenture, the Company will be responsible for making all calculations called for under the Indenture or

the Notes, including determinations of the Stock Price, Last Reported Sale Price, the Daily Conversion Value, the Daily Cash Amount,

the Daily Share Amount, the Daily VWAP, the Trading Price, accrued interest on the Notes, including any Special Interest, the Redemption

Price, the Fundamental Change Repurchase Price and the Conversion Rate (including adjustments to the Conversion Rate).

The

Company will make all calculations in good faith, and, absent manifest error, its calculations will be final and binding on all Holders.

The Company will provide a schedule of its calculations to the Trustee and the Conversion Agent, and each of the Trustee and the Conversion

Agent may rely conclusively on the accuracy of the Company’s calculations without independent verification. The Trustee will promptly

forward a copy of each such schedule to a Holder upon its written request therefor. For the avoidance of doubt, the Trustee will not

be obligated to make or confirm any calculations or other amounts called for under the Indenture or the Notes.

Section

10.11 Severability.

If

any provision of the Indenture or the Notes is invalid, illegal or unenforceable, then the validity, legality and enforceability of the

remaining provisions of the Indenture or the Notes will not in any way be affected or impaired thereby.

Section

10.12 Counterparts.

The

parties may sign any number of copies of this Supplemental Indenture. Each signed copy will be an original, and all of them together

represent the same agreement. Delivery of an executed counterpart of this Supplemental Indenture by facsimile, electronically in portable

document format or in any other format will be effective as delivery of a manually or electronically executed counterpart.

-65-

Section

10.13 Table of Contents, Headings, Etc.

The

table of contents and the headings of the Articles and Sections of this Supplemental Indenture have been inserted for convenience of

reference only, are not to be considered a part of the Indenture and will in no way modify or restrict any of the terms or provisions

of the Indenture.

Section

10.14 Withholding Taxes.

Each

Holder of a Note agrees, and each beneficial owner of an interest in a Note, by its acquisition of such interest, is deemed to agree,

that if the Company or other applicable withholding agent pays withholding taxes or backup withholding on behalf of such Holder or beneficial

owner as a result of an adjustment or the non-occurrence of an adjustment to the Conversion Rate, then the Company or such withholding

agent, as applicable, may, at its option, set off such payments against payments of cash or the delivery of other Conversion Consideration

on such Note, any payments on the Common Stock or sales proceeds received by, or other funds or assets of, such Holder or the beneficial

owner of such Note.

Section

10.15 Trust Indenture Act Controls.

If

any provision of the Indenture limits, qualifies or conflicts with another provision that is required or deemed to be included in the

Indenture by the Trust Indenture Act, such required or deemed provision of the Trust Indenture Act will control.

Ladies

and Gentlemen:

We

connection with the issuance and sale by the Company of $575,000,000 aggregate principal amount of 0.250% Convertible Senior Notes due

2032 (the “Notes”), convertible, at the Company’s election, into cash, common stock, par value $0.001 per share, of

the Company (the “Common Stock”) or a combination of cash and Common Stock. The Notes are being offered pursuant to the Registration

Statement on Form S-3 (File No. 333-292646) filed by the Company with the Securities and Exchange Commission (the “Commission”)

under the Securities Act of 1933, as amended (the “Act”), on January 9, 2026 (as so filed, the “Registration Statement”),

the base prospectus, dated January 9, 2026, included in the Registration Statement (the “Base Prospectus”), the preliminary

prospectus supplement, dated June 3, 2026, filed with the Commission pursuant to Rule 424(b) under the Act (together with the Base Prospectus,

the “Preliminary Prospectus Supplement”) and the final prospectus supplement, dated June 3, 2026, filed with the Commission

pursuant to Rule 424(b) under the Act (together with the Base Prospectus, the “Prospectus”). The Notes are being issued pursuant

to, and are governed by, an indenture (the “Base Indenture”), dated as of August 1, 2025, between the Company and U.S. Bank

Trust Company, National Association, as trustee (the “Trustee”), as supplemented by a second supplemental indenture (the

“Supplemental Indenture,” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”),

dated as of June 8, 2026, between the Company and the Trustee, and are being sold pursuant to an underwriting agreement, dated June 3,

2026, by and among Jefferies LLC, J.P. Morgan Securities LLC, TD Securities (USA) LLC and Guggenheim Securities, LLC as the representatives

of the several underwriters listed on Schedule A thereto, and the Company (the “Underwriting

Agreement”).

This

opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K.

In

rendering the opinions expressed herein, we have examined or are otherwise familiar with the Certificate

of Incorporation of the Company, as amended to the date hereof, and the Bylaws of the Company,

and we have reviewed originals, or copies certified or otherwise authenticated to our satisfaction, of (i)

the Registration Statement, (ii) the Preliminary Prospectus Supplement, (iii) the Prospectus, (iv) the Underwriting Agreement, (v) the

Indenture, (vi) executed copies of the global notes evidencing the Notes and (vii) the corporate actions taken by the Company in connection

with the authorization of the Underwriting Agreement, the Notes, the Indenture and the shares of Common Stock issuable upon conversion

of the Notes. We have also examined originals, or copies certified or otherwise authenticated to our satisfaction, of such corporate

records of the Company and other instruments, certificates of public officials and representatives of the Company, and other documents

as we have deemed necessary as a basis for the opinions hereinafter expressed and have made such examination of statutes and decisions

and reviewed such questions of law as we have considered necessary or appropriate for the purposes of this opinion letter.

June 8, 2026

Page 2

Based

on and subject to the foregoing and to the other assumptions, qualifications and limitations set forth herein, we are of the opinion

that:

1)

The

Notes have been duly authorized by all necessary corporate action on the part of the Company and have been duly executed by the Company

and, when authenticated by the Trustee in accordance with the provisions of the Indenture, and delivered to and paid for by the Underwriters

pursuant to the terms of the Underwriting Agreement, the Notes will constitute valid and legally binding obligations of the Company,

enforceable against the Company in accordance with their terms, except as the same may be limited by the effect of bankruptcy, insolvency,

receivership, voidable transactions, fraudulent conveyance, fraudulent transfer, reorganization, moratorium, assignment for the benefit

of creditors and other similar laws now or hereafter in effect relating to or affecting creditors’ rights generally and equitable

principles of general applicability (regardless of whether enforceability is considered in a proceeding in equity or at law) and

except further as enforcement thereof may be limited by any governmental authority that limits, delays or prohibits the making of

payments outside the United States.

2)

All

necessary action on the part of the Company has been taken to authorize the issuance of the shares of Common Stock of the Company

initially issuable upon conversion of the Notes (the “Underlying Shares”), and, (i) when any Underlying Shares are issued

by the Company upon due and proper conversion of the Notes by the applicable holder thereof in accordance with the terms of the Notes

and the Indenture, and (ii) upon the due registration

of issuance and constructive delivery through book entry of such Underlying Shares by the transfer agent and registrar therefor,

then, upon the happening of such events, such Underlying Shares will be validly issued, fully

paid and non-assessable.

We

have relied, as to certain relevant facts, upon representations made by the Company in the Underwriting Agreement, the Indenture and

the Notes, upon the assumptions set forth herein, and upon certificates of public officials and officers of the Company reasonably believed

by us to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification

thereof or other investigation. We have also relied, without investigation, upon the following assumptions: (i) natural persons acting

on behalf of the Company have sufficient legal capacity to enter into and perform, on behalf of the Company, the transaction in question

and to carry out their role in the transaction; (ii) each party to agreements or instruments relevant hereto (other than the Company)

has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreements or instruments enforceable

against it; (iii) each party to or having rights under agreements or instruments relevant hereto (other than the Company) has complied

with all legal requirements pertaining to its status (such as legal investment laws, foreign qualification statutes and business activity

reporting requirements) as such status relates to its rights to enforce such agreements or instruments against the Company; (iv) each

document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document

that is a copy conforms to an authentic original and all signatures on each such document, including electronic signatures, are genuine;

(v) all statutes, judicial and administrative decisions and rules and regulations of governmental agencies, constituting the law of the

opining jurisdictions, are publicly available to lawyers practicing in the relevant jurisdiction; (vi) all relevant statutes, rules,

regulations or agency actions are constitutional and valid unless a reported decision in the relevant jurisdiction has specifically addressed

but not resolved, or has established, its unconstitutionality or invalidity; (vii) there are no agreements or understandings among the

parties, written or oral, and there is no usage of trade or course of dealing among the parties that would, in either case, define, supplement

or qualify the agreements or instruments relevant hereto; and (viii) the

Company will comply with all applicable notice requirements regarding uncertificated shares provided in the General Corporation Law of

the State of Delaware.

Without

limiting any other qualifications set forth herein, the opinion expressed herein regarding the enforceability of the Notes is subject

to the effect of generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change

of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the enforcement

of provisions of instruments or agreements that purport to require waiver of the obligations of good faith, fair dealing, diligence and

reasonableness; (iii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iv) limit

the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of or contribution to

a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful

misconduct or unlawful conduct or insofar as such provisions otherwise contravene public policy; (v) may, where less than all of an instrument

or agreement may be unenforceable, limit the enforceability of the balance of the instrument or agreement to circumstances in which the

unenforceable portion is not an essential part of the agreed exchange; (vi) govern and afford judicial discretion regarding the determination

of damages and entitlement to attorneys’ fees and other costs; (vii) may permit a party who has materially failed to render or

offer performance required by an instrument or agreement to cure that failure unless either permitting a cure would unreasonably hinder

the aggrieved party from making substitute arrangements for performance or it is important under the circumstances to the aggrieved party

that performance occur by the date stated in the instrument or agreement; (viii) may limit the enforceability of provisions for the payment

of premiums upon mandatory prepayment to the extent any such payment constitutes, or is deemed to constitute, a penalty or forfeiture;

(ix) may require mitigation of damages; (x) provide a time limitation after which a remedy may not be enforced (i.e., statutes of limitation);

and (xi) may require that a claim with respect to any debt securities that are payable other than in U.S. dollars (or a foreign currency

judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable

law.

June 8, 2026

Page 3

We

express no opinion as to the enforceability or effect in the Notes of (i) any agreement to submit to the jurisdiction of any particular

court or other governmental authority (either as to personal jurisdiction or subject matter jurisdiction) (except to the extent such

agreement would be enforceable based on Section 5-1402 of the General Obligations Law of the State of New York), any provision restricting

access to courts (including without limitation agreements to arbitrate disputes), any waivers of the right to jury trial, any waivers

of service of process requirements that would otherwise be applicable, any provision relating to evidentiary standards, any agreement

that a judgment rendered by a court in one jurisdiction may be enforced in another jurisdiction or any provision otherwise affecting

the jurisdiction or venue of courts; (ii) any provision waiving or otherwise modifying legal, statutory or equitable defenses or other

procedural, judicial or substantive rights; or (iii) any provision that authorizes one party to act as attorney-in-fact for another party.

With

respect to our opinion regarding the Underlying Shares, we express no opinion to the extent that, notwithstanding the Company’s

current reservation of the maximum number of Underlying Shares as of the date hereof, future issuances of securities of the Company,

including the Underlying Shares, and/or antidilution adjustments to outstanding securities of the Company, including the Notes, may cause

the Notes to be convertible for more shares of Common Stock than the number that then remain authorized but unissued.

Our

opinions set forth herein are limited to the laws of the State of New York and the General Corporation Law of the State of Delaware,

and we express no opinion as to the effect on the matters covered by our opinions of any other law.

This

opinion letter is rendered as of the date first written above, and we assume no responsibility for updating this opinion letter or the

opinions set forth herein to take into account any event, action, interpretation or change in law or facts occurring subsequent to the

date hereof that may affect the validity of such opinions. This opinion letter is expressly limited to the matters set forth above, and

we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company, the Notes or the Underlying

Shares.

We

hereby consent to the filing of this opinion letter as an exhibit to the Current Report on Form 8-K of the Company filed with the Commission

on the date hereof and thereby incorporated by reference into the Registration Statement and to being named in the Prospectus included

therein under the caption “Legal Matters” with respect to matters stated therein. In giving such consent, we do not thereby

admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the

Commission thereunder with respect to any part of the

Registration Statement, including this opinion letter.

Very truly yours,

ABOUT

CELCUITY

Celcuity

is a clinical-stage biotechnology company focused on the development of targeted therapies for the treatment of multiple solid tumor

indications. The Company’s lead therapeutic candidate is gedatolisib, a kinase inhibitor of the PI3K/AKT/mTOR (“PAM”)

pathway that binds to all class I PI3K isoforms and the mTOR complexes, mTORC1 and mTORC2. By targeting all class I PI3K isoforms and

mTORC1/2, gedatolisib induces comprehensive inhibition of the PAM pathway. Its mechanism of action and pharmacokinetic properties are

differentiated from other currently approved and investigational therapies that target PI3Kα, AKT, or mTORC1 alone or together.

The Company’s Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib

in patients with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”)

locally advanced or metastatic breast cancer (“ABC”), has reported detailed results for both Study 1, which evaluated patients

with PIK3CA wild-type (“WT”) tumors, and Study 2, which evaluated patients with PIK3CA mutant-type (“MT”)

tumors. The Company’s Phase 3 clinical trial, VIKTORIA-2, is ongoing and incorporates two independent studies, Study 1 and Study

Celcuity

Inc. Announces Pricing of Upsized Public Offering of

0.250% Convertible Senior Notes Due 2032

MINNEAPOLIS,

June 3, 2026 – Celcuity Inc. (Nasdaq: CELC) (“Celcuity” or the “Company”), a clinical-stage biotechnology

company focused on the development of targeted therapies for the treatment of multiple solid tumor indications, today announced the pricing

of its upsized underwritten public offering of $500,000,000 aggregate principal amount of its 0.250% convertible senior notes due 2032

(the “Convertible Notes”). The aggregate principal amount of the offering was increased from the previously announced offering

size of $400,000,000.

The

Company has granted the underwriters of the offering a 30-day option to purchase up to an additional $75,000,000 aggregate principal

amount of the Convertible Notes, solely to cover over-allotments. The offering is expected to close on June 8, 2026, subject to satisfaction

of customary closing conditions.

The

Convertible Notes will be general, unsecured, senior obligations of the Company. The Convertible Notes will accrue interest payable semi-annually

in arrears on February 1 and August 1 of each year, beginning on February 1, 2027, at a rate equal to 0.250% per year. The Convertible

Notes will mature on August 1, 2032, unless earlier converted, redeemed or repurchased by the Company. The Convertible Notes will be

convertible at the option of the holders if certain conditions are met and during certain periods, based on an initial conversion rate

of 8.0302 shares of the Company’s common stock (the “Common Stock”) per $1,000 principal amount of the Convertible

Notes, which is equivalent to an initial conversion price of approximately $124.53 per share of Common Stock and represents a conversion

premium of approximately 40.0% above the last reported sale price of the Common Stock on June 3, 2026. The Company will settle conversions

of the Convertible Notes by paying or delivering, as applicable, cash, common stock or a combination of cash and shares of Common Stock,

at the Company’s election, based on the applicable conversion rate. If a “make-whole fundamental change” (as defined

in the indenture that will govern the Convertible Notes) occurs, then the Company will in certain circumstances increase the conversion

rate for a specified period of time.

The

Convertible Notes will be redeemable, in whole or in part (subject to certain limitations), at the Company’s option at any time,

and from time to time, on a redemption date on or after August 6, 2029 and on or before the 31st scheduled trading day immediately before

the maturity date, at a cash redemption price equal to the principal amount of the Convertible Notes to be redeemed, plus accrued and

unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Common Stock

exceeds 130% of the conversion price for the Convertible Notes on (1) each of at least 20 trading days, whether or not consecutive, during

the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption

notice; and (2) the trading day immediately before the date the Company sends such notice. In addition, calling any note for redemption

will constitute a make-whole fundamental change with respect to that note, in which case the conversion rate applicable to the conversion

of that note will be increased in certain circumstances if it is converted after it is called for redemption.

If

a “fundamental change” (as defined in the indenture that will govern the Convertible Notes) occurs, then, subject to certain

exceptions, noteholders may require the Company to repurchase their Convertible Notes at a cash repurchase price equal to the principal

amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change

repurchase date.

The

Company estimates that the net proceeds from the offering will be approximately $484.3 million (or approximately $557.0 million if the

underwriters of the offering exercise their over-allotment option in full), after deducting underwriting discounts and commissions and

the Company’s estimated offering expenses. The Company intends to use the net proceeds from the offering to repay in full all outstanding

obligations under its amended and restated loan agreement with Oxford Finance, LLC, as collateral agent, and the lenders party thereto,

and the remainder for working capital and general corporate purposes. General corporate purposes may include clinical trial expenditures,

commercial launch expenditures, commercialization expenditures, research and development expenditures, capital expenditures, expansion

of business development activities and other general corporate purposes. The Company may also use a portion of the proceeds for the potential

acquisition of businesses, technologies, and products, although it has no current binding understandings, commitments, or agreements

to do so.

ABOUT

CELCUITY

Celcuity

is a clinical-stage biotechnology company focused on the development of targeted therapies for the treatment of multiple solid tumor

indications. The Company’s lead therapeutic candidate is gedatolisib, a kinase inhibitor of the PI3K/AKT/mTOR (“PAM”)

pathway that binds to all class I PI3K isoforms and the mTOR complexes, mTORC1 and mTORC2. By targeting all class I PI3K isoforms and

mTORC1/2, gedatolisib induces comprehensive inhibition of the PAM pathway. Its mechanism of action and pharmacokinetic properties are

differentiated from other currently approved and investigational therapies that target PI3Kα, AKT, or mTORC1 alone or together.

The Company’s Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib

in patients with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”)

locally advanced or metastatic breast cancer (“ABC”), has reported detailed results for both Study 1, which evaluated patients

with PIK3CA wild-type (“WT”) tumors, and Study 2, which evaluated patients with PIK3CA mutant-type (“MT”)

tumors. The Company’s Phase 3 clinical trial, VIKTORIA-2, is ongoing and incorporates two independent studies, Study 1 and Study

2, evaluating two separate cohorts of patients with ABC who are treatment-naive in the advanced setting. Study 1 is evaluating gedatolisib

combined with palbociclib and fulvestrant as first-line treatment for patients with endocrine-resistant HR+/HER2- ABC. Study 2 is evaluating

gedatolisib combined with palbociclib and letrozole as first-line treatment for patients with endocrine-sensitive HR+/HER2- ABC. The

Company’s Phase 1b/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic

castration-resistant prostate cancer, is ongoing. The Company is headquartered in Minneapolis, Minnesota.
