applicable tax withholding amounts (as determined pursuant to Paragraph 16 of this Agreement and Section 15 of the Plan) for such exercise.

7. Manner of Exercise. The Performance Stock Option shall be exercised by giving written notice of exercise in accordance with the manner prescribed by the Committee. Such notice shall be deemed to have been given when hand-delivered, e-mailed or mailed, first class postage prepaid, and shall be irrevocable once given.

8. Restrictions on Sale of Shares. Notwithstanding anything to the contrary in this Agreement or the Plan, any Shares delivered to the Grantee pursuant to the exercise of Earned Options shall not, unless otherwise determined in the sole discretion of the Committee, be sold, transferred, assigned, alienated, disposed, hypothecated, conveyed, pledged or encumbered in any manner whatsoever (other than in order to satisfy withholding taxes) by Grantee (or, if applicable, the Grantee's estate or beneficiaries) prior to the first anniversary of the date that the Performance Stock Option becomes earned and vested.

9. Nontransferability of Performance Stock Option. The Performance Stock Option may not be transferred or assigned by the Grantee otherwise than by will or the laws of descent and distribution or be exercised during his life other than by the Grantee or for his benefit by his attorney-in-fact or guardian. Any attempt at assignment, transfer, pledge or disposition of the Performance Stock Option contrary to the provisions hereof or the levy of any execution, attachment or similar process upon the Performance Stock Option shall be null and void and without effect. Any exercise of the Performance Stock Option by a person other than the Grantee shall be accompanied by appropriate proofs of the right of such person to exercise the Performance Stock Option.

10. Securities Laws. The Committee may from time to time impose any conditions on the exercise of the Performance Stock Option as it deems necessary or appropriate to comply with the then-existing requirements of the 1933 Act or the 1934 Act, including Rule 16b-3 (or any similar rule) of the Securities and Exchange Commission. If the listing, registration or qualification of Shares issuable on the exercise of the Performance Stock Option upon any securities exchange or under any federal or state law, or the consent or approval of any governmental regulatory body is necessary as a condition of or in connection with the purchase of such Shares, the Company shall not be obligated to issue or deliver the certificates representing the Shares otherwise issuable on the exercise of the Performance Stock Option unless and until such listing, registration, qualification, consent or approval shall have been effected or obtained. If registration is considered unnecessary by the Company or its counsel, the Company may cause a legend to be placed on such Shares calling attention to the fact that they have been acquired for investment and have not been registered.

11. Repayment. Notwithstanding anything to the contrary contained herein, the Performance Stock Option shall be subject to any clawback or recoupment arrangements or policies the Company has in place from time to time (including, without limitation, the Mirion Technologies, Inc. Clawback Policy), and the Committee may, to the extent permitted or shall, to the extent required, by applicable law and stock exchange rules or by any applicable Company policy or arrangement, (i) cancel or require reimbursement of any Shares issued or cash received

upon the exercise of the Performance Stock Option or sale of Shares underlying such option and (ii) effect the cancellation of Earned Options or unvested Performance Stock Options.

12. Rights Prior to Exercise. The Grantee shall not have any right as a stockholder with respect to any Shares subject to his Performance Stock Options until the Performance Stock Option shall have been exercised in accordance with the terms of the Plan and this Agreement and the Company shall have delivered the Shares. In the event that the Grantee's Termination of Service is for Cause, upon a determination by the Committee, the Grantee shall automatically forfeit all Shares otherwise subject to delivery upon exercise of an Performance Stock Option but for which the Company has not yet delivered the Shares.

13. Status of Performance Stock Option; Interpretation. The Performance Stock Option is intended to be a non-qualified stock option. Accordingly, it is intended that the transfer of property pursuant to the exercise of the Performance Stock Option be subject to federal income tax in accordance with Section 83 of the Code. The Performance Stock Option is not intended to qualify as an incentive stock option within the meaning of Section 422 of the Code. The interpretation and construction of any provision of this Performance Stock Option or the Plan made by the Committee shall be final and conclusive and, insofar as possible, shall be consistent with the intention expressed in this Paragraph 13.

14. Performance Stock Option Not to Affect Service. The Performance Stock Option granted hereunder shall not confer upon the Grantee any right to continue in service as an employee, officer or director of the Company or any subsidiary of the Company.

15. Miscellaneous.

(a) The address for the Grantee to which notice, demands and other communications to be given or delivered under or by reason of the provisions hereof shall be the Grantee's address contained in the Company's personnel records, or such other address as the Grantee may provide to the Company by written notice.

(b) This Agreement may be executed in one or more counterparts all of which taken together will constitute one and the same instrument.

(c) The validity, performance, construction and effect of this Agreement shall be governed by the laws of the State of Delaware, without giving effect to principles of conflicts of law.

(d) No amendment or modification of any provision of this Agreement that has a material adverse effect on Grantee shall be effective unless signed in writing by or on behalf of the Company and Grantee; provided that the Company may amend or modify this Agreement without Grantee's consent in accordance with the provisions of the Plan or as otherwise set forth in this Agreement. No waiver of any breach or condition of this Agreement shall be deemed to be a waiver of any other or subsequent breach or condition, whether of like or different nature. Any amendment or modification of or to any provision of this Agreement, or

any waiver of any provision of this Agreement, shall be effective only in the specific instance and for the specific purpose for which such amendment, modification or waiver is made or given.

(e) This Agreement and the Plan and any other agreements, schedules, exhibits and other documents referred to herein or therein constitute the entire agreement and understanding between the parties in respect of the subject matter hereof and supersede all prior and contemporaneous arrangements, agreements and understandings, both oral and written, whether in term sheets, presentations or otherwise, between the parties with respect to the subject matter hereof, including without limitation, the Employment Agreement (and any vesting provisions thereunder). For the avoidance of doubt, any provisions in the Employment Agreement that provide for vesting of outstanding equity awards will have no application to the Options granted hereunder.

(f) This Agreement shall inure to the benefit of and be binding upon the Company and Grantee and their respective heirs, successors, legal representatives and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the Company and Grantee, and their respective heirs, successors, legal representatives and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

(g) If any term or provision of this Agreement is held to be invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect any other term or provision hereof and this Agreement shall continue in full force and effect as if such invalid or unenforceable term or provision (to the extent of the invalidity or unenforceability) had not been contained herein.
