Exhibit 10.1
TIGO ENERGY, INC. EMPLOYEE STOCK PURCHASE PLAN
Section 1.
Purpose. This Tigo Energy, Inc. Employee Stock Purchase Plan (the “Plan”) is intended to provide Eligible
Employees of the Company and the Participating Companies with an opportunity to acquire a proprietary interest in the Company
through the purchase of Shares. The Plan has two components: (a) one component (the “423 Component”) is intended
to qualify as an “employee stock purchase plan” under Section 423(b) of the Code, and the Plan will be interpreted in a
manner that is consistent with that intent, and (b) the other component (the “Non-423 Component”), which is not
intended to qualify as an “employee stock purchase plan” under Section 423 of the Code, authorizes the grant of options
pursuant to rules, procedures or sub-plans adopted by the Committee that are designed to achieve tax, securities laws or other
objectives for Eligible Employees. Rights granted under the Non-423 Component shall be granted pursuant to separate Offerings
containing such sub-plans, appendices, rules or procedures as may be adopted by the Committee and designed to achieve tax,
securities laws or other objectives for Eligible Employees and Participating Companies but shall not be intended to qualify as an
“employee stock purchase plan” under Section 423 of the Code. Except as otherwise provided herein or as may be
determined by the Committee, the Non-423 Component will operate and be administered in the same manner as the 423 Component.
Offerings intended to be made under the Non-423 Component will be designated as such by the Committee at or prior to the time of
such Offering.
For purposes of the Plan, the Committee may designate
separate Offerings under the Plan in which Eligible Employees will participate. The terms of these Offerings need not be identical, even
if the dates of the applicable Offering Period(s) in each such Offering are identical, provided that the terms of participation are the
same within each separate Offering under the 423 Component (as determined under Section 423 of the Code). Solely by way of example and
without limiting the foregoing, the Company could, but shall not be required to, provide for simultaneous Offerings under the 423 Component
and the Non-423 Component of the Plan.

amend and rescind rules relating to the Plan’s administration and take any other actions necessary or desirable for the
administration of the Plan including, without limitation, adopting sub-plans applicable to particular Participating Companies or
locations, which sub-plans may be designed to be outside the scope of Section 423 of the Code and under the Non-423 Component. With
respect to the Non-423 Component, the rules of such sub-plans may take precedence over other provisions of the Plan, with the
exception of Section 13 hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of the Plan shall
govern the operation of such sub-plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency or

Section 4. Eligibility.
In order to participate in an Offering, an Eligible Employee must deliver a completed Enrollment Form to the Company at least five (5)
business days prior to the Offering Date (unless a different time is set by the Committee for all Eligible Employees with respect to
such Offering) and must elect his or her payroll deduction rate as described in Section 6. Notwithstanding any provision of the
Plan to the contrary, no Eligible Employee shall be granted an option under the Plan if (i) immediately after the grant of the option,
such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the
Code) would own capital stock of the Company or hold outstanding options to purchase stock possessing 5% or more of the total combined
voting power or value of all classes of stock of the Company or any Subsidiary or (ii) such option would permit his or her rights to
purchase stock under all employee stock purchase plans (described in Section 423 of the Code) of the Company and its Subsidiaries to
accrue at a rate that exceeds $25,000 of the Fair Market Value of such stock (determined at the time the option is granted) for each
calendar year in which such option is outstanding at any time, in accordance with the provisions of Section 423(b)(8) of the Code.
Section 5. Offering Periods.
The Plan shall be implemented by a series of Offering Periods, each of which shall be six (6) months in duration, with new Offering Periods
commencing on or about March 1 and September 1 of each year (or such other times as determined by the Committee). The Committee shall
have, prior to the commencement of a particular Offering Period, the authority to change the duration, frequency, start and end dates
of Offering Periods (subject to a maximum Offering Period of twenty-seven (27) months).
Section 6. Participation.
(a) Enrollment; Payroll
Deductions. An Eligible Employee may elect to participate in the Plan by properly completing an Enrollment Form, which may be
electronic, and submitting it to the Company, in accordance with the enrollment procedures established by the Committee.
Participation in the Plan is entirely voluntary. By submitting an Enrollment Form, which may be electronic, the Eligible Employee
authorizes payroll deductions from his or her pay check in an amount equal to at least one percent (1%), but not more than twenty
percent (20%) of his or her Compensation on each pay day occurring during an Offering Period (or such other maximum percentage as
the Committee may establish from time to time before an Offering Period begins). Payroll deductions shall commence as soon as
practicable following the Offering Date and end on the latest practicable payroll date on or before the Purchase Date. The Company
shall maintain records of all payroll deductions but shall have no obligation to pay interest on payroll deductions or to hold such
amounts in a trust or in any segregated account. Unless expressly permitted by the Committee, a Participant may not make any
separate contributions or payments to the Plan.
5
(b) Election Changes. During
an Offering Period, a Participant may decrease or increase his or her rate of payroll deductions applicable to such Offering Period only
once. To make such a change, the Participant must submit a new Enrollment Form authorizing the new rate of payroll deductions at least
fifteen (15) days before the Purchase Date. A Participant may decrease or increase his or her rate of payroll deductions for future Offering
Periods by submitting a new Enrollment Form authorizing the new rate of payroll deductions at least fifteen days before the start of the
next Offering Period.
(c) Automatic Re-enrollment.
The deduction rate selected in the Enrollment Form shall remain in effect for subsequent Offering Periods unless the Participant (i) submits
a new Enrollment Form authorizing a new level of payroll deductions in accordance with this Section 6, (ii) withdraws from the Plan
in accordance with Section 10, or (iii) terminates employment or otherwise becomes ineligible to participate in the Plan.
(d) Non-U.S. Employees. In
order to facilitate participation in the Plan, the Committee may provide for such special terms applicable to Participants who are citizens
or residents of a non-U.S. jurisdiction, or who are employed by a Participating Company outside of the United States, as the Committee
may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Except as permitted by Section 423
of the Code, with respect to the 423 Component, such special terms may not be more favorable than the terms of rights granted under the
423 Component to Eligible Employees who are residents of the United States. Such special terms may be set forth in an addendum to the
Plan in the form of an appendix or sub-plan (which appendix or sub-plan may be designed to govern Offerings under the 423 Component or
the Non-423 Component, as determined by the Committee). With respect to the Non-423 Component only, to the extent that the terms and conditions
set forth in an appendix or sub-plan conflict with any provisions of the Plan, the provisions of the appendix or sub-plan shall govern.
Without limiting the foregoing, the Committee is specifically authorized to adopt rules and procedures, with respect to Participants who
are non-U.S. nationals or employed in non-U.S. jurisdictions, regarding the exclusion of particular Subsidiaries from participation in
the Plan, eligibility to participate, the definition of Compensation, handling of payroll deductions or other contributions by Participants,
payment of interest, conversion of local currency, data privacy security, payroll tax, withholding procedures, establishment of bank or
trust accounts to hold payroll deductions or contributions.
Section 7. Grant of Option.
On each Offering Date, each Participant in the applicable Offering Period shall be granted an option to purchase, on the Purchase Date,
a number of Shares determined by dividing the Participant’s accumulated payroll deductions by the applicable Purchase Price; provided,
that the maximum number of Shares that may be purchased by each Participant during an Offering Period shall not exceed 25,000 Shares
(subject to adjustment in accordance with Section 18 and the limitations set forth in Section 4 and Section 13 of the
Plan) (the “Offering Period Limit”).
6
Section 8. Exercise of
Option/Purchase of Shares. A Participant’s option to purchase Shares will be exercised automatically on the Purchase Date of
each Offering Period. The Participant’s accumulated payroll deductions will be used to purchase the maximum number of whole Shares
that can be purchased with the amounts in the Participant’s notional account, subject to the Offering Period Limit and the limitations
set forth in Section 4 and Section 13 of the Plan. No fractional Shares may be purchased, but contributions unused in a given
Offering Period due to being less than the cost of a Share will be carried forward to the next Offering Period, subject to earlier withdrawal
by the Participant in accordance with Section 10 or termination of employment or change in employment status in accordance with Section
11. During a Participant’s lifetime, the Participant’s option to purchase Shares under the Plan is exercisable only by the
Participant.
Section 9. Transfer of
Shares. As soon as administratively practicable after each Purchase Date, the Company will arrange for the delivery to each Participant
of the Shares purchased upon exercise of his or her option. The Committee may permit or require that the Shares be deposited directly
into an ESPP Share Account established in the name of the Participant with a Designated Broker and may require that the Shares be retained
with such Designated Broker for a specified period of time. Participants will not have any voting, dividend or other rights of a shareholder
with respect to the Shares subject to any option granted hereunder until such Shares have been delivered pursuant to this Section
9.
Section 10. Withdrawal.
(a) Withdrawal
Procedure. A Participant may withdraw from an Offering by submitting to the Company a revised Enrollment Form indicating his or her
election to withdraw at least fifteen (15) days before the Purchase Date. The accumulated payroll deductions held on behalf of a
Participant in his or her notional account (that have not been used to purchase Shares) shall be paid to the Participant promptly
following receipt of the Participant’s Enrollment Form indicating his or her election to withdraw and the Participant’s
option shall be automatically terminated. If a Participant withdraws from an Offering Period, no payroll deductions will be made
during any succeeding Offering Period, unless the Participant re-enrolls in accordance with Section 6(a) of the Plan.
(b) Effect on Succeeding Offering
Periods. A Participant’s election to withdraw from an Offering Period will not have any effect upon his or her eligibility to participate
in succeeding Offering Periods that commence following the completion of the Offering Period from which the Participant withdraws.
Section 11. Termination
of Employment; Change in Employment Status.
(a) Notwithstanding
Section 10, upon termination of a Participant’s employment for any reason prior to the Purchase Date, including death,
disability or retirement, or a change in the Participant’s employment status following which the Participant is no longer an
Eligible Employee, the Participant will be deemed to have withdrawn from an Offering in accordance with Section 10 and the
payroll deductions in the Participant’s notional account (that have not been used to purchase Shares) shall be returned to the
Participant, or in the case of the Participant’s death, to the person(s) entitled to such amounts by will or the laws of
descent and distribution, and the Participant’s option to purchase Shares shall be automatically terminated. If the
Participant’s termination of employment or change in status occurs within ten (10) days before a Purchase Date, the
accumulated payroll deductions shall be used to purchase Shares on the Purchase Date.
7
(b) Unless otherwise determined
by the Committee, a Participant whose employment transfers or whose employment terminates with an immediate rehire (with no break in service)
by or between the Company or a Participating Company will not be treated as having terminated employment for purposes of participating
in the Plan or an Offering; however, if a Participant transfers from an Offering under the 423 Component to an Offering under the Non-423
Component, the exercise of the Participant’s option to purchase Shares will be qualified under the 423 Component only to the extent
that such exercise complies with Section 423 of the Code. If a Participant transfers from an Offering under the Non-423 Component to an
Offering under the 423 Component, the exercise of the Participant’s option to purchase Shares will remain non-qualified under the
Non-423 Component.
Section 12. Interest.
No interest shall accrue on or be payable with respect to the payroll deductions of a Participant in the Plan.
Section 13. Shares Reserved
for Plan.
(a) Number of Shares. The
maximum number of Shares available for issuance under the Plan shall initially not exceed in the aggregate 1,000,000 Shares, subject to
adjustment as provided in Section 18. The Shares may be newly issued Shares, treasury Shares or Shares acquired on the open market.
If any purchase of Shares pursuant to an option under the Plan is not consummated, the Shares not purchased under such option will again
become available for issuance under the Plan.
(b) Over-subscribed Offerings.
The number of Shares which a Participant may purchase in an Offering under the Plan may be reduced if the Offering is over-subscribed.
No option granted under the Plan shall permit a Participant to purchase Shares which, if added together with the total number of Shares
purchased by all other Participants in such Offering would exceed the total number of Shares remaining available under the Plan. If the
Committee determines that, on a particular Purchase Date, the number of Shares with respect to which options are to be exercised exceeds
the number of Shares then available under the Plan, the Company shall make a pro rata allocation of the Shares remaining available for
purchase in as uniform a manner as practicable and as the Committee determines to be equitable.
Section 14. Transferability.
No payroll deductions credited to a Participant, nor any rights with respect to the exercise of an option or any rights to receive Shares
hereunder may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution,
or as provided in Section 17) by the Participant. Any attempt to assign, transfer, pledge or otherwise dispose of such rights or
amounts shall be without effect.
Section 15. Application
of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose
to the extent permitted by Applicable Law, and the Company shall not be required to segregate such payroll deductions or contributions.
8
Section 16. Statements.
Participants will be provided with statements at least annually which shall set forth the contributions made by the Participant to the
Plan, the Purchase Price of any Shares purchased with accumulated funds, the number of Shares purchased, and any payroll deduction amounts
remaining in the Participant’s notional account.
Section 17. Designation
of Beneficiary. If permitted by the Committee, a Participant may file, on forms supplied by the Committee, a written designation of
beneficiary who, in the event of the Participant’s death, is to receive any Shares from the Participant’s ESPP Share Account
or any payroll deduction amounts remaining in the Participant’s notional account.
Section 18. Adjustments
Upon Changes in Capitalization; Dissolution or Liquidation; Corporate Transactions.
(a) Adjustments. In the event
that any dividend or other distribution (whether in the form of cash, Shares, or other property), recapitalization, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities
of the Company, or other change in the Company’s structure affecting the Shares occurs, then in order to prevent dilution or enlargement
of the benefits or potential benefits intended to be made available under the Plan, the Committee will, in such manner as it deems equitable,
adjust the number of Shares and class of Shares that may be delivered under the Plan, the Purchase Price per Share and the number of Shares
covered by each outstanding option under the Plan, and the numerical limits of Section 7 and Section 13.
(b) Dissolution or Liquidation.
Unless otherwise determined by the Committee, in the event of a proposed dissolution or liquidation of the Company, any Offering Period
then in progress will be shortened by setting a new Purchase Date and the Offering Period will end immediately prior to the proposed dissolution
or liquidation. The new Purchase Date will be before the date of the Company’s proposed dissolution or liquidation. Before the new
Purchase Date, the Committee will provide each Participant with written notice, which may be electronic, of the new Purchase Date and
that the Participant’s option will be exercised automatically on such date, unless before such time, the Participant has withdrawn
from the Offering in accordance with Section 10 (or deemed to have withdrawn in accordance with Section 11).
Section 19. Corporate Transaction.
In the event of a Corporate Transaction, each outstanding option will be assumed or an equivalent option substituted by the successor
corporation or a parent or Subsidiary of such successor corporation. If the successor corporation refuses to assume or substitute the
option, the Offering Period with respect to which the option relates will be shortened by setting a new Purchase Date on which the Offering
Period will end. The new Purchase Date will occur before the date of the Corporate Transaction. Prior to the new Purchase Date, the Committee
will provide each Participant with written notice, which may be electronic, of the new Purchase Date and that the Participant’s
option will be exercised automatically on such date, unless before such date, the Participant has withdrawn (or, pursuant to Section
11, been deemed to have withdrawn) from the Offering in accordance with Section 10. Notwithstanding the foregoing, in the event of
a Corporate Transaction, the Committee may also elect to terminate all outstanding Offering Periods in accordance with Section 20(i).
9
Section 20. General Provisions.
(a) Equal Rights and Privileges.
Notwithstanding any provision of the Plan to the contrary and in accordance with Section 423 of the Code, all Eligible Employees who are
granted options under the Plan shall have the same rights and privileges.
(b) No Right to Continued
Service. Neither the Plan nor any compensation paid hereunder will confer on any Participant the right to continue as an Employee or in
any other capacity.
(c) Rights as Shareholder.
A Participant will become a shareholder with respect to the Shares that are purchased pursuant to options granted under the Plan when
the Shares are transferred to the Participant or, if applicable, to the Participant’s ESPP Share Account. A Participant will have
no rights as a shareholder with respect to Shares for which an election to participate in an Offering Period has been made until such
Participant becomes a shareholder as provided herein.
(d) Successors and Assigns.
The Plan shall be binding on the Company and its successors and assigns.
(e) Entire Plan. The Plan
constitutes the entire plan with respect to the subject matter hereof and supersedes all prior plans with respect to the subject matter
hereof.
(f) Compliance with Law. The
obligations of the Company with respect to payments under the Plan are subject to compliance with all Applicable Laws and regulations.
Shares shall not be issued with respect to an option granted under the Plan unless the exercise of such option and the issuance and delivery
of the Shares pursuant thereto shall comply with all Applicable Laws, including, without limitation, the Securities Act, the Exchange
Act, and the requirements of any stock exchange upon which the Shares may then be listed.
(g) Disqualifying Dispositions.
Each Participant shall give the Company prompt written notice of any disposition or other transfer of Shares acquired pursuant to the
exercise of an option acquired under the Plan, if such disposition or transfer is made within two years after the Offering Date or within
one year after the Purchase Date. Notwithstanding the foregoing, Participants shall not transfer Shares acquired pursuant to the exercise
of an option acquired under the Plan to a broker other than the Designated Broker within two years after the Offering Date or within one
year after the Purchase Date.
(h) Term of Plan. The Plan
shall become effective on the Effective Date and, unless terminated earlier pursuant to Section 20(i), shall have a term of ten (10) years.
(i) Amendment or Termination.
The Committee may, in its sole discretion, amend, suspend or terminate the Plan at any time and for any reason. If the Plan is terminated,
the Committee may elect to terminate all outstanding Offering Periods either immediately or once Shares have been purchased on the next
Purchase Date (which may, in the discretion of the Committee, be accelerated) or permit Offering Periods to expire in accordance with
their terms (and subject to any adjustment in accordance with Section 18). If any Offering Period is terminated before its scheduled
expiration, all amounts that have not been used to purchase Shares will be returned to Participants (without interest, except as otherwise
required by law) as soon as administratively practicable.
10
(j) Governing Law. The Plan
and any agreements hereunder shall be administered, interpreted and enforced in accordance with the laws of the State of Delaware, disregarding
any state’s choice of law principles requiring the application of a jurisdiction’s laws other than the State of Delaware.
The competent courts located in Delaware shall have exclusive jurisdiction over any dispute arising out of or in connection with the Plan
and any award granted hereunder.
(k) Shareholder Approval.
The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is
adopted by the Board.
(l) Section 423. The Plan
(other than the Non-423 Component) is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code.
Any provision of the Plan (other than the Non-423 Component) that is inconsistent with Section 423 of the Code shall be reformed to comply
with Section 423 of the Code.
(m) Section 409A; Limitation
of Liability. The Plan and all options are intended to be exempt from Section 409A of the Code as “statutory stock options”
within the meaning of Treasury Regulation §1.409A-1(b)(5)(ii), and the Plan and the options will be interpreted and administered
accordingly. Notwithstanding anything to the contrary in the Plan, neither the Company nor the Committee, nor any person acting on behalf
of the Company or the Committee, will be liable to any Participant or other person by reason of any acceleration of income, any additional
tax, or any other tax or liability asserted by reason of the failure of the Plan or any option to be exempt from or satisfy the requirements
of Section 409A of the Code.
(n) Foreign Exchange Considerations.
If any Contributions under the Plan are made in any currency other than U.S. dollars, such Contributions will be converted to U.S. dollars
on or prior to the Purchase Date using a prevailing exchange rate in effect at the time such conversion is performed, as determined by
the Administrator. Neither the Company nor any U.S. or non-U.S. Affiliate shall be liable for any foreign exchange rate fluctuation between
local currency and the U.S. dollar that may affect the value of the options granted to under the Plan, or of any amounts due under the
Plan or as a result of the subsequent sale of any Shares acquired under the Plan. By their participation in the Plan, all Participants
acknowledge and agree that they may be responsible for reporting inbound transactions or fund transfers that exceed a certain amount.
Participants are advised to seek appropriate professional advice as to how the exchange control regulations apply to their participation
in the Plan and their specific situation; understanding that the relevant laws and regulations can change frequently and occasionally
on a retroactive basis.
(o) Withholding. To the
extent required by applicable Federal, state or local law, a Participant must make arrangements satisfactory to the Company for the
payment of any withholding or similar tax obligations that arise in connection with the Plan. At any time, the Company or any
Subsidiary may, but will not be obligated to, withhold from a Participant’s compensation the amount necessary for the Company
or any Subsidiary to meet applicable withholding obligations, including any withholding required to make available to the Company or
any Subsidiary any tax deductions or benefits attributable to the sale or early disposition of Shares by such Participant. In
addition, the Company or any Subsidiary may, but will not be obligated to, withhold from the proceeds of the sale of Shares or any
other method of withholding that the Company or any Subsidiary deems appropriate to the extent permitted by, where applicable,
Treasury Regulation Section 1.423-2(f). The Company will not be required to issue any Shares under the Plan until such obligations
are satisfied.
11
(p) Severability. If any provision
of the Plan shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not affect any other
provision hereof, and the Plan shall be construed as if such invalid or unenforceable provision were omitted.
(q) Headings. The headings
of sections herein are included solely for convenience and shall not affect the meaning of any of the provisions of the Plan.
(r) Participating Company.
A Participating Company may withdraw from the Plan as of any Offering Date by giving written notice to the Board, which notice must be
received by at least thirty (30) days prior to such Offering Date.
(s) Paperless Administration.
If the Company establishes, for itself or using the services of a third party, an automated system for the documentation and administration
of the Plan, such as a system using an internet website or interactive voice response, then the paperless documentation may be permitted
through the use of such an automated system.
(t) Data Privacy. As a condition
to participating in the Plan, each Participant explicitly and unambiguously consents to the collection, use and transfer, in electronic
or other form, of personal data as described in this Section 20(t) by and among the Company and its Subsidiaries and Affiliates exclusively
for implementing, administering and managing the Participant’s participation in the Plan. The Company and its Subsidiaries and Affiliates
may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate;
social security, insurance number or other identification number; salary; nationality; job title(s); any Shares held in the Company or
its Subsidiaries and Affiliates; and Share details, to implement, manage and administer the Plan and Shares (the “Data”).
The Company and its Subsidiaries and Affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage
a Participant’s participation in the Plan, and the Company and its Subsidiaries and Affiliates may transfer the Data to third parties
assisting the Company with Plan implementation, administration and management. These recipients may be located in the Participant’s
country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the recipients’
country. By participating in the Plan, each Participant authorizes the recipients to receive, possess, use, retain and transfer the Data,
in electronic or other form, to implement, administer and manage the Participant’s participation in the Plan, including any required
Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit any Shares. The Data related
to a Participant will be held only as long as necessary to implement, administer, and manage the Participant’s participation in
the Plan. A Participant may, at any time, view the Data that the Company holds regarding the Participant, request additional information
about the storage and processing of the Data regarding the Participant, recommend any necessary corrections to the Data regarding the
Participant or refuse or withdraw the consents in this Section 20(t) in writing, without cost, by contacting the local human resources
representative. The Company may cancel Participant’s ability to participate in the Plan and, in the Committee’s discretion,
the Participant may forfeit any outstanding Shares if the Participant refuses or withdraws the consents in this Section 20(t).
