2026 LONG-TERM INCENTIVE PLAN

Adopted by the Board of Directors

On March 11, 2026

Approved by the Shareholders

On May 5, 2026

1. ADMINISTRATION

Subject to the express provisions of the Plan,

the Administrator has the authority to interpret the Plan; determine eligibility for and grant Awards; determine, modify or waive the

terms and conditions of any Award; prescribe forms, rules and procedures (which it may modify or waive); and otherwise do all things necessary

to implement the Plan. Once an Award has been communicated in writing to a Participant, the Administrator may not, without the Participant’s

consent, alter the terms of the Award so as to materially affect adversely the Participant’s rights under the Award, unless the

Administrator has expressly reserved the right to do so or pursuant to Section 9 of this Plan. To the extent permitted by applicable law,

including under Sections 152(b) and 157(c) of the Delaware General Corporation Law, the Administrator may delegate some or all of its

authority under the Plan, including the authority to grant or administer Awards (except that such delegation shall not be applicable to

any Award for a person then covered by Section 16 of the Securities Exchange Act of 1934, as amended), to such persons or groups of persons

as it deems necessary, appropriate or advisable under conditions or limitations that the Administrator may set at the time of the delegation.

2. LIMITS ON AWARDS UNDER THE PLAN

(a)       NUMBER

OF SHARES. Subject to adjustments as provided in Section ‎2(b)‎5(b),

the total number of shares of Stock subject to Awards delivered under the Plan, in the aggregate, may not exceed 4,825,000 (the “Fungible

Pool Limit”). Each share of Stock issued or to be issued in connection with any Full-Value Award shall be counted against the Fungible

Pool Limit as 2.0 Fungible Pool Units. Stock Options, SARs and other Awards that were granted on or after the Effective Date and that

expire no more than ten (10) years from the date of grant, shall be counted against the Fungible Pool Limit as one (1.0) Fungible Pool

Unit. (For these purposes, the number of shares of Stock taken into account with respect to a SAR shall be the number of shares of Stock

underlying the SAR at grant (i.e., not the final number of shares of Stock delivered upon exercise of the SAR)). For purposes of the second

sentence of this Section ‎2(a), shares that

have been forfeited or cancelled in accordance with the terms of the applicable Award shall not be considered to have been delivered under

the Plan; however, shares held back in satisfaction of the exercise price or tax withholding requirements from shares that would otherwise

have been delivered pursuant to an Award will be considered to have been delivered under the Plan and will not be added back to the pool

of available shares. In addition, shares of Stock that have been repurchased by the Company with proceeds obtained in connection with

the exercise of outstanding Awards shall not be added into the pool of available shares. Any shares of Stock that again become available

for grant pursuant to this Section ‎2(a) shall

be added back to the pool of available shares.

For purposes of clarity, in calculating the number

of shares of Stock remaining under the Fungible Pool Limit, the Administrator will not increase the number of available Fungible Pool

Units for shares of Stock delivered under an Award (i.e., previously acquired Shares tendered by the Participant in payment of the exercise

price or of withholding taxes). The Administrator shall determine the appropriate methodology for calculating the number of shares of

Stock issued pursuant to the Plan.

(b)       TYPE

OF SHARES. Stock delivered by the Company under the Plan may be authorized but unissued Stock or previously issued Stock acquired

by the Company and held in treasury. No fractional shares of Stock will be delivered under the Plan.

(c)       NON-EMPLOYEE

DIRECTOR LIMIT. A Participant who is a non-employee member of the Board may not receive compensation for any calendar year

(including the calendar year in which the non-employee member is first elected or appointed to the Board) in excess of $750,000 in the

aggregate, including cash payments and Awards. For purposes of applying the limitation in this Section ‎2(c),

Awards will be considered compensation in the calendar year in which the date of grant occurs and the value of such Award shall be its

grant date fair value for financial reporting purposes.

(d)       ISO

SHARE LIMIT. Subject to adjustments as provided in Section ‎5(b),

the maximum number of shares of Stock available for issuance with respect to ISOs under the Plan shall be 4,825,000.

3. ELIGIBILITY AND PARTICIPATION

The Administrator will select Participants from

among those key Employees, directors and other individuals or entities providing services to the Company or its Affiliates who, in the

opinion of the Administrator, are in a position to make a significant contribution to the success of the Company and its Affiliates. Eligibility

for ISOs is further limited to those individuals whose employment status would qualify them for the tax treatment described in Sections

421 and 422 of the Code.

4. RULES APPLICABLE TO AWARDS

(a)       ALL

AWARDS

(1)       TERMS

OF AWARDS. All Awards of Stock Options and SARs granted hereunder shall have a term of not to exceed ten (10) years from the date of grant.

The Administrator shall determine all other terms of all Awards subject to the limitations provided herein.

(2)       PERFORMANCE

CRITERIA. Where rights under an Award depend in whole or in part on satisfaction of Performance Criteria, actions by the Company that

have an effect, however material, on such Performance Criteria or on the likelihood that they will be satisfied will not be deemed an

amendment or alteration of the Award.

2

(3)       ALTERNATIVE

SETTLEMENT. The Company may at any time extinguish rights under an Award in exchange for payment in cash, Stock (subject to the limitations

of Section ‎2) or other property on such terms as the Administrator

determines, PROVIDED the holder of the Award consents to such exchange, PROVIDED FURTHER, no such exchange will be made where the cash,

Stock or property to be received has a fair market value greater than the Award being extinguished, or where any such exchange would violate

Section ‎4(a)(8) of this Plan.

(4)       TRANSFERABILITY

OF AWARDS. Awards may not be transferred other than by will or by the laws of descent and distribution and during a Participant’s

lifetime an Award requiring exercise may be exercised only by the Participant (or in the event of the Participant’s incapacity,

the person or persons legally appointed to act on the Participant’s behalf).

(5)       VESTING,

ETC. Without limiting the generality of Section ‎1, the Administrator

may determine the time or times at which an Award will vest (i.e., become free of forfeiture restrictions) or become exercisable and the

terms on which an Award requiring exercise will remain exercisable. Notwithstanding anything contained herein to the contrary, and subject

to Section ‎5, Awards shall vest over a period of not less

than one year following the date of grant (the “Minimum Vesting Requirements”); PROVIDED, however, that the Administrator

may, in its sole discretion, (a) accelerate the vesting of Awards or otherwise lapse or waive the Minimum Vesting Requirements upon (x)

the Participant’s death or Disability or (y) a Change in Control (subject to the requirements of Section ‎13)

and (b) grant Awards that are not subject to the Minimum Vesting Requirements with respect to 5% or less of the number of shares reserved

for issuance under the Plan.

Unless otherwise provided by Section ‎4(d)

with respect to Performance Awards or if the Administrator expressly provides otherwise:

(A)       immediately

upon the cessation of a Participant’s employment or other service relationship with the Company and its Affiliates, all Awards (other

than Stock Options and SARs) held by the Participant (or by a permitted transferee under Section ‎4(a)(4))

immediately prior to such cessation of employment or other service relationship will be forfeited if not then vested and, where exercisability

is relevant, will cease to be exercisable;

(B)       except

as provided in clauses ‎(C) and ‎(D)

below, all Stock Options and SARs held by a Participant (or by a permitted transferee under Section ‎4(a)(4))

immediately prior to the cessation of the Participant’s employment or other service relationship for reasons other than Disability

or death, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of three months or (ii) the period ending

on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section ‎4(a)(v),

and shall thereupon terminate;

3

(C)       all

Stock Options and SARs held by a Participant (or by a permitted transferee under Section ‎4(a)(4))

immediately prior to the Participant’s Disability or death, to the extent then exercisable, will remain exercisable for the lesser

of (i) the one-year period ending with the first anniversary of the Participant’s Disability or death or (ii) the period ending

on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section ‎4(a)(5)(C),

and shall thereupon terminate; and

(D)       all

Stock Options and SARs held by a Participant (or by a permitted transferee of the Participant under Section ‎4(a)(4))

whose cessation of employment or other service relationship is determined by the Administrator in its sole discretion to result from reasons

which cast such discredit on the Participant as to justify immediate termination of the Award shall immediately terminate upon such cessation.

Unless the Administrator expressly provides otherwise,

a Participant’s “employment or other service relationship with the Company and its Affiliates” will be deemed to have

ceased, in the case of an employee Participant, upon termination of the Participant’s employment with the Company and its Affiliates

(whether or not the Participant continues in the service of the Company or its Affiliates in some capacity other than that of an employee

of the Company or its Affiliates), and in the case of any other Participant, when the service relationship in respect of which the Award

was granted terminates (whether or not the Participant continues in the service of the Company or its Affiliates in some other capacity).

(6)       TAXES.

The Administrator will make such provision for the withholding of taxes as it deems necessary. The Administrator may authorize the Company

to withhold from any Award granted or any payment due or transfer made under any Award or under the Plan, or from any compensation or

other amount owing to the Participant, the amount (in cash, shares of Stock, other Awards, other property, net settlement, or any combination

thereof) of applicable withholding taxes due in respect of an Award, its exercise or settlement, or any payment or transfer under such

Award or under the Plan and to take such other action (including providing for elective payment of such amounts in cash or Shares by such

Participant) as may be necessary to satisfy all obligations for the payment of such taxes and, unless otherwise determined by the Administrator

in its discretion, to the extent such withholding would not result in liability classification of such Award (or any portion thereof)

pursuant to FASB ASC Subtopic 718-10. For the avoidance of doubt, Stock may be tendered or held back by the Company in excess of the minimum

amount required to be withheld for Federal, state, and local taxes.

As provided in Section ‎2(a)

of this Plan, in the event shares of Stock are held back from an Award in satisfaction of tax withholding requirements, such shares will

nonetheless be considered to have been delivered under the Plan and will not be added back to the pool of available shares.

4

(7)       DIVIDEND

EQUIVALENTS, ETC. The Administrator may provide for the payment of amounts in lieu of cash dividends or other cash distributions with

respect to Stock subject to any Full Value Award if and in such manner as it deems appropriate. Notwithstanding anything contained herein

to the contrary, and without limiting the generality of Section ‎4(d)(6)4(d)(6)(10),

in no event shall an Award provide for any dividend or dividend equivalents to be payable to the Participant in respect of such Award

prior to the time at which such Award (or the applicable portion thereof) vests (and, in the case of a Performance Award, the applicable

performance condition is achieved).

(8)       RIGHTS

LIMITED. Nothing in the Plan shall be construed as giving any person the right to continued employment or service with the Company or

its Affiliates, or any rights as a shareholder except as to shares of Stock actually issued under the Plan. The loss of existing or potential

profit in Awards will not constitute an element of damages in the event of termination of employment or service for any reason, even if

the termination is in violation of an obligation of the Company or Affiliate to the Participant. No Participant or other person shall

have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants under the

Plan. The terms and conditions of Awards need not be the same with respect to each recipient. Any Award granted under the Plan shall be

a one-time Award that does not constitute a promise of future grants. Any Award granted under the Plan shall not be a part of a Participant’s

base salary or wages and will not be taken into account in determining any other employment-related rights such Participant may have,

such as rights to pension or severance pay. The Company, in its sole discretion, maintains the right to make available future grants under

the Plan. Unless stated herein, no Participant or other person shall acquire any rights, remedies, benefits or obligations. Nothing contained

in the Plan shall prevent the Company from adopting or continuing in effect other or additional compensation arrangements, and such arrangements

may be either generally applicable or applicable only in specific cases. Neither the Plan nor any Award shall create or be construed to

create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other person. To

the extent that any person acquires a right to receive payments from the Company pursuant to an Award, such right shall be no greater

than the right of any unsecured general creditor of the Company.

(9)       OPTION

AND SAR REPRICING. Notwithstanding anything in the Plan to the contrary, except as provided in Section ‎5(b),

no action (including the repurchase of Options, SARs or similar Awards (in each case, that are “out of the money”) for cash

and/or other property) shall directly or indirectly, through cancellation and grant or regrant of any Award, repurchase or any other method,

reduce, or have the effect of reducing, the exercise or hurdle price of any Award established at the time of grant thereof without approval

of the stockholders of the Company.

(10)       FORFEITURE/CLAWBACK.

The Committee may determine that any Award under this Plan shall be subject to provisions for the forfeiture and/or reimbursement of all

amounts received in connection with an Award in the event of breach of noncompetition, nonsolicitation or confidentiality agreements.

All Awards

5

granted under this Plan are subject to recoupment,

to the extent applicable, under the Company’s Financial Statement Compensation Recoupment Policy, as may be revised from time to

time, and/or any other recoupment, clawback or similar policy that may be approved by the Board or any committee thereof. Notwithstanding

any other provision of this Plan, a Participant shall be required to reimburse the Company amounts received in connection with an Award

to the extent required under Section 304 of the Sarbanes-Oxley Act of 2002 and Section 954 of the Dodd-Frank Wall Street Reform and Consumer

Protection Act of 2010, and any rules promulgated thereunder and any other regulatory regimes, including Rule 10D-1 of the Securities

Exchange Act of 1934, as amended, and Rule 303A.14 of the New York Stock Exchange Listed Company Manual.

(11)       STOCK

OWNERSHIP GUIDELINES/HOLDING PERIODS. The Committee may require that any Stock acquired by a Participant in connection with an Award granted

under this Plan shall be subject to stock ownership guidelines, a minimum holding period or similar requirement under which a Participant

shall not be permitted to transfer, sell, pledge, hedge, hypothecate or otherwise dispose of any such Stock.

(b)       AWARDS

REQUIRING EXERCISE

(1)       TIME

AND MANNER OF EXERCISE. Unless the Administrator expressly provides otherwise, (a) an Award requiring exercise by the holder will not

be deemed to have been exercised until the Administrator receives a written notice of exercise (in a form acceptable to the Administrator)

signed by the appropriate person and accompanied by any payment required under the Award or adequate provision therefore, as set forth

in Section ‎4(b)(3); and (b) if the Award is exercised by any

person other than the Participant, the Administrator may require satisfactory evidence that the person exercising the Award has the right

to do so.

(2)       EXERCISE

PRICE. The Administrator shall determine the exercise price of each Stock Option and SAR; PROVIDED, that each Stock Option and SAR must

have an exercise price that is not less than the fair market value of the Stock subject to the Stock Option and SAR, determined as of

the date of grant. An ISO granted to an Employee described in Section 422(b)(6) of the Code must have an exercise price that is not less

than 110% of such fair market value.

(3)       PAYMENT

OF EXERCISE PRICE, IF ANY. Where the exercise of an Award is to be accompanied by payment, the Administrator may determine the required

or permitted forms of payment, subject to the following: (a) all payments will be by cash or check acceptable to the Administrator, or,

if so permitted by the Administrator (with the consent of the optionee of an ISO if permitted after the grant), (i) through the delivery

of shares of Stock which have been outstanding for at least six months (unless the Administrator approves a shorter period) and which

have a fair market value equal to the exercise price, (ii) by delivery of a promissory note of the person exercising the Award to the

Company, payable on such terms as are specified by the Administrator, (iii) if the Stock is publicly traded, by delivery of an unconditional

and irrevocable undertaking by a broker to deliver promptly to the Company sufficient funds to pay the exercise price (i.e., by

broker-assisted cashless exercise), (iv) by net settlement, (v) by

6

any combination of the foregoing permissible forms

of payment; and (b) where shares of Stock issued under an Award are part of an original issue of shares, the Award shall require an exercise

price equal to at least the par value of such shares.

(4)       GRANT

OF STOCK OPTIONS. Each Stock Option awarded under the Plan shall be deemed to have been awarded as a non-ISO (and to have been so designated

by its terms) unless the Administrator expressly provides for ISO treatment that the Stock Option is to be treated as an ISO.

(c)       AWARDS

NOT REQUIRING EXERCISE

Awards of Restricted Stock and Unrestricted Stock

may be made in return for either (1) services determined by the Administrator to have a value not less than the par value of the Awarded

shares of Stock, or (2) cash or other property having a value not less than the par value of the Awarded shares of Stock plus such additional

amounts (if any) as the Administrator may determine payable in such combination and type of cash, other property (of any kind) or services

as the Administrator may determine.

(d)       PERFORMANCE

AWARDS

Performance Awards may be granted to Participants

as follows:

(1)       Prior

to the grant of any Performance Award, the Administrator shall establish for each such award (i) performance levels at which 100% of the

award shall be earned and a range (which need not be the same for all awards) within which greater and lesser percentages shall be earned

and (ii) a performance period (which shall not be less than 12 months) which shall be determined at time of grant.

(2)       With

respect to the performance levels to be established pursuant to Section ‎4(d)(1),

the specific measures for each grant shall be established by the Administrator at the time of such grant. In creating these measures,

the Administrator may establish the specific goals based upon or relating to any Performance Criteria (as defined below).

(3)       The

percentage of each Performance Award to be distributed to an employee shall be determined by the Administrator on the basis of the performance

levels established for such award and on the basis of individual performance in satisfaction of the Performance Award during such period.

Any Performance Award as determined and adjusted pursuant to this Section is herein referred to as a “Final Award”.

(4)       All

Final Awards which have vested in accordance with the provisions of Sections ‎4(d)(5)

and ‎4(d)(6) shall be granted as soon as practicable following

the end of the related vesting period. Final awards shall be granted in the form of Restricted Stock, unrestricted Stock, Deferred Stock,

Cash Performance Awards, or cash or any combination thereof, as the Administrator shall determine.

(5)       Performance

Awards that have become Final Awards may be subject to a vesting schedule established by the Administrator. Except as otherwise

7

provided in this Plan, no Final Award (or portion

thereof) subject to a vesting schedule shall be paid prior to vesting. The Administrator shall have the authority to modify a vesting

schedule as may be necessary or appropriate in order to implement the purposes of this Plan.

(6)       No holder

of a Performance Award shall have any rights to dividends or interest or other rights of a stockholder with respect to a Performance Award

prior to such Performance Award’s becoming a Final Award.

5. EFFECT OF CERTAIN TRANSACTIONS

(a)       MERGERS,

ETC. Other than in connection with Awards that are denominated and subject to settlement in cash, Awards shall not vest

in connection with a Change in Control unless such Change in Control is accompanied by a “double trigger event”. For this

purpose, a “double trigger event” occurs in connection with a Change in Control if (1) the Award is not appropriately assumed

nor an equivalent award substituted by the surviving, continuing, successor or purchasing company or other business entity or parent thereof,

as the case may be, and (2) at the time of, or within 12 months following the Change in Control, the Participant incurs a termination

of employment without Cause or for Good Reason.

Upon a Change in Control “double trigger

event”: (i) in the case of a Stock Option or SAR, the Stock Option or SAR shall become fully vested and exercisable immediately

upon the occurrence of the double trigger event; (ii) in the case of Restricted Stock, Deferred Stock or restricted stock units (in each

case other than an award of Restricted Stock, award of Deferred Stock or award of restricted stock units that is a Performance Award),

the restriction period shall lapse and the Restricted Stock, Deferred Stock or restricted stock unit (as applicable) shall fully vest

immediately upon the occurrence of the double trigger event; and (iii) in the case of a Performance Award, payment under the Award shall

be made on a pro rata basis, based on the number of completed months during the performance period, unless specifically noted otherwise

in the applicable award agreement.

(b)       CHANGES

IN AND DISTRIBUTIONS WITH RESPECT TO THE STOCK

(1)       BASIC

ADJUSTMENT PROVISIONS. In the event of a stock dividend, stock split or combination of shares, recapitalization or other change in the

Company’s capital structure, the Administrator will make appropriate adjustments to the maximum number of shares that may be delivered

under the Plan under Section ‎2(a), and will also make appropriate

adjustments to the number and kind of shares of stock or securities subject to Awards then outstanding or subsequently granted, any exercise

prices relating to Awards and any other provision of Awards affected by such change.

(2)       CERTAIN

OTHER ADJUSTMENTS. The Administrator may also make adjustments of the type described in paragraph (1) above to take into account distributions

to common stockholders other than those provided for in Section ‎5(a)

and

8

‎5(b)(1),

or any other event, if the Administrator determines that adjustments are appropriate to avoid distortion in the operation of the Plan

and to preserve the value of Awards made hereunder; PROVIDED, that no change shall be made to ISOs except to the extent consistent with

their continued qualification under Section 422 of the Code.

(3)       CONTINUING

APPLICATION OF PLAN TERMS. References in the Plan to shares of Stock shall be construed to include any stock or securities resulting from

an adjustment pursuant to Section ‎5(b)(1) or ‎5(b)(2)

above.

6. LEGAL CONDITIONS ON DELIVERY OF STOCK

The Company will not be obligated to deliver any

shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock previously delivered under the Plan until the Company’s

counsel has approved all legal matters in connection with the issuance and delivery of such shares; if the outstanding Stock is at the

time of delivery listed on any stock exchange or national market system, the shares to be delivered have been listed or authorized to

be listed on such exchange or system upon official notice of issuance; and all conditions of the Award have been satisfied or waived.

If the sale of Stock has not been registered under the Securities Act of 1933, as amended, the Company may require, as a condition to

exercise of the Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of such

Act. The Company may require that certificates evidencing Stock issued under the Plan bear an appropriate legend reflecting any restriction

on transfer applicable to such Stock.

7. AMENDMENT AND TERMINATION

The Administrator may at any time or times amend

the Plan or any outstanding Award for any purpose which may at the time be permitted by law, or may at any time terminate the Plan as

to any further grants of Awards; PROVIDED, that (except to the extent expressly required or permitted by the Plan) no such amendment will,

without the approval of the stockholders of the Company, effectuate a change for which stockholder approval is required under the rules

of the New York Stock Exchange (which includes any “material revision” as defined under the rules of the New York Stock Exchange)

or in order for the Plan to continue to qualify under Section 422 of the Code and to have an Award comply with, or avoid adverse consequences

under, Section 409A of the Code.

8. NON-LIMITATION OF THE COMPANY’S RIGHTS

The existence of the Plan or the grant of any Award

shall not in any way affect the Company’s right to award a person bonuses or other compensation in addition to Awards under the

Plan.

9. COMPLIANCE WITH APPLICABLE LAW

If any provision of the Plan or any applicable

award agreement is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction, or as to any person or Award,

or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed

amended to conform to

9

applicable laws, or if it cannot be so construed

or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the applicable award agreement,

such provision shall be stricken as to such jurisdiction, person or Award, and the remainder of the Plan and any such applicable award

agreement shall remain in full force and effect.

1. Purpose

The Board of Directors (the “Board”)

of Charles River Laboratories international Inc. (the “Company”) has established the 2026 Long-Term Incentive Plan

(the “Plan”) for the benefit of certain employees and/or corporate officers of the Company including those (i.e. Employees

As specifically authorized by the Plan, the Administrator

intends to establish a French Sub-Plan of the Plan for the purpose of granting Restricted Stock Units and Performance Stock Units, as

The Shares acquired must be existing or newly issued

securities representing the capital with random return. In the case of existing shares, the Company must hold those no later than the

(ii)       The

grant of RSU/PSU would not result if subsequently vested in the holding by such French Participant of ten percent (10%) or more of the

Share Capital of the Company as at the Grant Date.

These limits are assessed at the time of the grant

decision by the Board of Directors.

Outstanding unvested RSU/PSU shall be taken into

account to determine the present limit of 10%, within the limit that only Shares directly held by a French Participant for less than seven

5. Restriction Period

The RSU and PSU granted to French Participants

may be subject to restriction period and forfeiture conditions. The terms of the Award will be set forth in a Award Agreement.

5.1. Vesting Period

5.1.1 General

No Award Agreement shall provide for vesting of

the Award thereunder earlier than the 1st anniversary of the applicable Grant Date (“Vesting Period”).

During the Vesting Period, the ownership of the

Shares cannot be transferred to the French Participant who only holds a conditional right and is not entitled to any shareholder’s

right during the Vesting Period (no dividends rights, no voting rights).

5.1.2 Presence-based conditions

The RSU/PSU vesting may be conditional upon the

fulfilment of a presence-based condition imposed on the Participant by the Administrator.

21

The Award Agreement shall specify whether vesting

may be subject to any such condition in order, for the Participant, to be informed about such condition before the beginning of a vesting

period.

5.1.3 Performance-based conditions

The RSU/PSU vesting may be conditional upon the

fulfilment of objective performance-based conditions imposed on the Participant by the Administrator.

The Award Agreement shall specify whether vesting

may be subject to any such condition in order, for the Participant, to be informed about such condition before the beginning of a vesting

period.

5.2. Holding Period

To the extent that the RSU/PSU vest less than two

(2) years after the Grant Date, the Shares acquired on Vesting Date shall be subject to a holding period (“Holding Period”),

so that there is a minimum two-year (2-year) period between the Grant Date and the date of free disposal of the Shares by the French Participant,

as required by Article L.225-197-1 of the French Commercial Code.

When an Award is subject to a Holding Period, the

Shares may be delivered to the French Participant in settlement of the RSU and/or PSU, provided the French Participant shall agree not

to sell, transfer, assign, mortgage, charge or otherwise dispose of the Shares during the Holding Period.

5.3. Delivery

As a general rule, the Participant may receive

delivery of the Shares after the RSU/PSU have become vested.

Provided that the Participant has complied with

its obligations set forth in Section 5.1, the Company shall arrange the transfer or issue of relevant Share to the Participant.

5.4.         Share

issued following RSU/PSU Vesting Date shall be issued in the name of the Participant, except in cases where RSU/PSU are inherited

under the laws of inheritance. Cessation of employment contract / Corporate Officer mandate

In the event of termination of employment contract

or cessation of corporate office mandate prior to the Vesting Date, all unvested RSUs/PSUs shall automatically and irrevocably lapse as

of the date of such termination or cessation.

Except as otherwise expressly decided by the Administrator

at its sole discretion, the Plan shall not result in the acceleration of the Vesting Period nor in the waiver of any applicable Holding

Period, where such acceleration or waiver would result in a period of less than two (2) years between the Grant Date and the date on which

the Shares may be freely disposed of by the French Participant, except in the strictly permitted circumstances set out below:

22

5.4.1 Death

In case of French Participant’s death before

the RSU/PSU have vested, her/his heir(s), as determined under applicable law, may request, within six (6) months as from the date of death,

the immediate vesting and delivery of the RSU/PSU, as provided by Article L.255-197-3 of the French Commercial Code.

In case of French Participant’s death after

the RSU/PSU have vested and before the expiry of any applicable Holding Period, his /her Shares shall cease to be subject to the Holding

Period.

5.4.2 Disability

In case of French Participant’s Disability

before the RSU/PSU have vested, the RSU/PSU shall vest immediately, in such proportion as determined by the Administrator in its absolute

discretion, in relation to the fulfillment of the performance-based conditions and regarding any other condition as at the time of cessation

of employment, and such other factors as the Administrator may consider relevant.

In case of French Participant’s Disability

after the RSU/PSU have vested and before the expiry of any applicable Holding Period, his /her Shares shall cease immediately to be subject

to the Holding Period.

5.5. Share sale restrictions

5.5.1 Closed Period

In accordance with the Article L22-10-59 of the

French Commercial Code, Shares vested and acquired by a French participant must not be sold during the following periods:

(i)       Within

30 calendar days before the announcement of an interim financial report or an end-of-year report which the granting Company is required

to make public;

(ii)       By

the members of the “Conseil d’Administration”   (Board of Directors) or “Conseil de Surveillance”

(Supervisory Board), by the members of the “Directoire”   (Executive Board) or exercising the powers “Directeur

Général”   (Managing Director) or “Directeur Général Délégué”

(Delegated Managing Director), and by employees having knowledge of any inside information, within the meaning of article 7 of EU Regulation

n°596/2014 which has not been made public.

Strict compliance with the above periods may not

be required when the local legislation applicable to the Company provides for periods of share sale restrictions that, while not corresponding

exactly to the above periods, offer equivalent guarantees.

23

5.5.2 Specific share sale restriction for Corporate Officers

A specific share sale restriction for Corporate

Officers, fully or partially until the termination of their duties, is provided by the Article L225-197-1 II of the French Commercial

Code but shall not apply to Corporate Officers of the Company’s French Subsidiary.

6. Rights in connection to Shares

6.1. Rights

Until the Vesting Date, the property of the Shares

is not transferred to the French Participant. No right to vote or to receive dividends or any other rights as a Company’s shareholder

shall exist with respect to the Share.

6.2. Dividends equivalents

No Dividend Equivalents shall be paid with respect

to RSU and PSU.

6.3. Alternative settlement

No adjustment shall be made for a dividend or other

right for which the record date is prior to the date the Share ownership is transferred to the French Participant.

7. Employment rights

Neither the French Sub-Plan nor any RSU/PSU grant

shall confer upon any French Participant any right with respect to continuing the French Participant’s relationship as an Employee

of the Company, nor shall be construed as part of any employment contracts that a French Subsidiary has with its Employees.

8. Adjustment and certain other events change

In accordance with article L.225-197-1, III of

the French Commercial Code, in the event of an exchange of shares for non-cash consideration resulting from a merger or a demerger occurring

during the Vesting Period or Holding Period and in the event of such share exchange resulting from a public offer, a subdivision or consolidation

of shares, the provisions of the French Sub-Plan shall remain applicable (including the vesting and holding requirements) as those applying

to the original RSU and/or PSU.

In the event of another transformation, reorganization

or any other corporate event or of equity restructuring occurring after the grant of the RSU and/or PSU, the Administrator shall take

all necessary actions, while the event is in progress, in order to determine the impact of this operation on the Awards and, as far as

possible, in order to maintain the rights of the French Participants and the neutrality of the operation.

Nevertheless, the Administrator, at its discretion,

may determine to make adjustments in the case of a transaction for which adjustments are not authorized under

24

French law, in which case the RSU/PSU may no longer

qualify as “qualified” RSU/PSU (as admitted under French law).

In any case, no cash payment shall be made, in

particular to compensate for any fractional shares, and the beneficiary must expressly waive any compensation that could be granted to

them in connection with the adjustment.

9. Amendment and termination

9.1.       With

the exception of provisions falling within the exclusive competence of the Company’s Extraordinary General Meeting and approved

by said meeting, the Administrator may amend or depart from the provisions of this French Sub-Plan in the best interests of the Company.

However, such amendments shall have no effect on the rights and conditions of any Awards granted or fully vested prior to such amendment.

9.2.       No

amendment may be made to this French Sub-Plan that would affect the acquired rights of the French Participants without their prior written

consent, unless such amendment results from a newly enacted legislative or regulatory provision or from any other provision having binding

legal effect on the Company or on Company’s Subsidiary and entailing legal, tax or social consequences. In such a case, the amendments

made to this French Sub-Plan shall not give rise to any right to compensation for the French Participants, even if such amendments affect

their rights, whether generally or in view of their personal situation.

9.3.       This

French Sub-Plan shall automatically be binding upon the respective successors, heirs and assigns of each French Participant (including

any minor or legally incapacitated heirs of the French Participant and, where applicable, the French Participant’s executor).

10. Taxes

The Company or its French Subsidiaries shall have

the right to require payment from a French Participant to cover any applicable withholding or other employment taxes due with respect

to Awards granted hereunder or shall have the right to deduct any applicable withholding or employment taxes due from other compensation

income paid to the French Participants.

No shares underlying an Award may be withheld/net-shared

under the French Sub-Plan. In addition, no shares underlying an Award may be sold prior to the second anniversary of the Grant Date to

satisfy any social security or tax withholding due for Awards granted further to the French Sub-Plan for French Participants.

11. Validity

The fact that any provision of this French Sub-Plan

becomes null and void, unenforceable or obsolete shall not affect the validity or enforceability of the other provisions of this French

Sub-Plan, which shall continue to remain in full force and effect.

25

12. Interpretation and Applicable Regulations

12.1.       It

is intended that RSU/PSU granted under this French Sub-Plan shall qualify for the specific tax and social security treatment applicable

to RSU/PSU granted under Sections L. 225-197-1 to L. 225-197-5 of the French Commercial Code, as amended, and in accordance with the relevant

provisions set forth by French tax and social security laws. The terms of this French Sub-Plan shall be interpreted accordingly and in

accordance with the relevant guidelines published by French tax and social security administrations and subject to the fulfilment of certain

legal, tax and reporting obligations, if applicable.

12.2.       Although

this French Sub-Plan is aimed at addressing and complying with the requirements of applicable tax law and circulars, each French Participant

is advised to consult with his/her counsel about his/her tax status and tax treatment of RSU and PSU granted under this French Sub-Plan.

12.3.       Unless

the context otherwise requires, words in the singular shall include the plural and vice versa, and words importing the masculine gender

shall include the feminine and vice versa.

12.4.       The

French Sub-Plan provisions shall be governed by and construed in accordance with French laws.

13. Effective Date

This French Sub-Plan was approved by the Company’s

shareholders at the annual shareholders meeting held on May 5, 2026 with authorization to the Administrator of the Company to grant RSU

and PSU thereunder on May 5, 2026, as required under French law. It is applicable as of May 5, 2026. The authorization may be used by

the Administrator under the French Sub-Plan until the termination of the Plan, subject to applicable French law.
