This letter (this “Letter Agreement”) is being delivered to you in connection with the Business Combination Agreement (together with the exhibits and schedules thereto, as amended, supplemented, otherwise modified, the “Business Combination Agreement”), dated as of the date hereof, by and among GS Acquisition Holdings Corp II, a Delaware corporation (the “SPAC”), Mirion Technologies (TopCo), Ltd., a Jersey private company (the “Company”), CCP IX LP No. 1, CCP IX LP No. 2, CCP IX Co-Investment LP and CCP IX Co-Investment No. 2 LP (collectively, the “Charterhouse Parties”), each of the other persons set forth on Annex I thereto and the other holders of Existing Company Shares from time to time becoming a party thereto by executing a Joinder Agreement in the form of Exhibit H thereto (collectively, together with each Charterhouse Party, the “Sellers”), and hereby amends and restates in its entirety that certain letter, dated June 29, 2020, from GS Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and the other undersigned persons (each such other undersigned person, an “Insider” and collectively, the “Insiders”) to the SPAC (the “Prior Letter Agreement”). Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Business Combination Agreement. Certain capitalized terms used herein are defined in paragraph 9 hereof.

In order to induce the Company, the Sellers and the SPAC to enter into the Business Combination Agreement and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Sponsor and each of the Insiders hereby severally (and not jointly and severally) agrees with the SPAC, and at all times prior to any valid termination of the Business Combination Agreement, the Company and the Charterhouse Parties, as follows:

1. The Sponsor and each Insider hereby unconditionally and irrevocably agrees: (i) that at any duly called meeting of the stockholders of the SPAC (or any adjournment or postponement thereof), and in any action by written consent of the stockholders of the SPAC requested by the SPAC’s board of directors or to be undertaken as contemplated by the Transactions, the Sponsor and each such Insider shall, if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause all of its Shares to be counted as present thereat for purposes of establishing a quorum, and it shall vote or consent (or cause to be voted or consented), in person, in writing or by proxy, all of its Shares (a) in favor of the adoption of the Business Combination Agreement and approval of the Transactions and all other Transaction Proposals (and any actions required in furtherance thereof), (b) against any action, proposal, transaction or agreement that would result in a breach of any representation, warranty, covenant, obligation or agreement of the SPAC contained in the Business Combination Agreement, (c) in favor of any other proposals set forth in the SPAC’s proxy statement to be filed by the SPAC with the U.S. Securities and Exchange Commission (the “Commission”) relating to the Transactions (including any proxy supplements thereto, the “Proxy Statement”), (d) for any proposal to adjourn or postpone the applicable stockholder meeting to a later date if (and only if) (1) there are not

sufficient votes for approval of the Business Combination Agreement and any other proposals related thereto, as set forth in the Proxy Statement, on the dates on which such meetings are held or (2) the Closing condition in Section 11.03(d) of the Business Combination Agreement has not been satisfied, and (e) against the following actions or proposals: (1) any Business Combination Proposal or any other proposal in opposition to approval of the Business Combination Agreement or in competition with the Business Combination Agreement; and (2) (A) any change in the present capitalization of the SPAC or any amendment of the SPAC’s Charter (as defined below), except to the extent expressly contemplated by the Business Combination Agreement, (B) any liquidation, dissolution or other change in the SPAC’s corporate structure or business, (C) any action, proposal, transaction or agreement that would result in a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of the Sponsor or such Insider under this Letter Agreement, and (D) any other action or proposal involving the SPAC or any of its subsidiaries that is intended or would reasonably be expected to prevent, delay or impede the timely consummation of the Transactions and (ii) not to redeem, elect to redeem or tender or submit for redemption, or knowingly cause any other Person to do any such thing on its behalf, any Shares owned by it in connection with such stockholder approval or proposed Business Combination, or in connection with any vote to amend the SPAC’s Charter or otherwise in connection with the Transactions. Prior to any valid termination of the Business Combination Agreement, the Sponsor and each Insider shall be bound by and comply with Sections 8.08 (Exclusivity) and 8.06 (Public Announcements) of the Business Combination Agreement (and any relevant definitions contained in any such Sections), which Sections apply mutatis mutandis, as if such Person were a signatory to the Business Combination Agreement with respect to such provisions. The obligations of the Sponsor and the Insiders specified in this paragraph 1 shall apply whether or not the Transactions or any action described above is recommended by the SPAC’s board of directors or any such recommendation changes while this Letter Agreement remains in force.

The Sponsor and each Insider hereby agrees that in the event that the SPAC fails to consummate a Business Combination by June 29, 2022, or such later period approved by the SPAC’s stockholders in accordance with the SPAC’s amended and restated certificate of incorporation (the “Charter”), the Sponsor and each Insider shall take all reasonable steps to cause the SPAC to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten (10) Business Days thereafter, subject to lawfully available funds therefor, redeem 100% of the Class A Common Shares sold as part of the Units in the IPO (the “Offering Shares”), at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable) and less up to $100,000 of interest to pay dissolution expenses, divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the SPAC’s remaining stockholders and the SPAC’s board of directors, dissolve and liquidate, subject in each case to the SPAC’s obligations under Delaware law to provide for claims of creditors and the other requirements of applicable law. The Sponsor and each Insider agrees to not propose any amendment to the SPAC’s Charter that would modify the substance or timing of the SPAC’s obligation to redeem 100% of the Offering Shares if the SPAC does not complete a Business Combination within the required time periods set forth in the Charter, or with respect to any other material provisions relating to stockholders’ rights or pre-

initial Business Combination activity, unless the SPAC provides its Public Stockholders with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Offering Shares.

The Sponsor and each Insider agrees and acknowledges that, with respect to the Founder Shares held by it, it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the SPAC as a result of any liquidation of the SPAC. The Sponsor and each Insider hereby further waives, with respect to any Shares held by it, any redemption rights, if any, it may have in connection with (x) the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or in the context of a tender offer made by the SPAC to purchase Class A Common Shares and (y) a stockholder vote to approve an amendment to the Charter (A) to modify the substance or timing of the SPAC’s obligation to allow redemptions in connection with the SPAC’s initial Business Combination or to redeem 100% of the Offering Shares if the SPAC has not consummated its initial Business Combination within 24 months from the closing of the IPO or (B) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity (although the Sponsor and the Insiders and their respective Affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the SPAC fails to consummate a Business Combination within the time period set forth in the Charter).

2. Without limiting their obligations under paragraph 5 below, during the period commencing on the date hereof and ending on the earlier of (a) the valid termination of the Business Combination Agreement or (b) the Closing, the Sponsor and each Insider shall not, without the prior written consent of the SPAC, Transfer any Units, Shares, warrants to purchase Class A Common Shares (“Warrants”) or any securities convertible into, or exercisable, or exchangeable for, Class A Common Shares owned by it. In the event that (i) any Class A Common Shares, Warrants or other equity securities of the SPAC are issued to the Sponsor or any Insider after the date hereof pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of Shares or Warrants, on or affecting the Shares or Warrants owned by the Sponsor or any Insider or otherwise, (ii) the Sponsor or any Insider purchases or otherwise acquires beneficial ownership of any Shares, Warrants or other equity securities of the SPAC after the date hereof or (iii) the Sponsor or any Insider acquires the right to vote, direct the voting of or share in the voting of any Shares, Warrants or other equity securities of the SPAC after the date hereof (such Shares, Warrants or other equity securities of the SPAC described in clauses (i), (ii) and (iii), the “New Shares”), then such New Shares acquired or purchased by the Sponsor or any Insider shall be subject to the terms of this paragraph 2 and paragraph 1 above to the same extent as if they constituted the Shares or Warrants owned by the Sponsor or any Insider as of the date hereof.

3. In the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other stockholders, members or managers of the Sponsor or any other Insider) agrees to indemnify and hold harmless the SPAC against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any

litigation, whether pending or threatened, or any claim whatsoever) to which the SPAC may become subject as a result of any claim by (i) any third party (other than the SPAC’s independent registered public accounting firm) for services rendered or products sold to the SPAC or (ii) a prospective target business with which the SPAC has entered into a letter of intent, confidentiality or similar agreement for a Business Combination (a “Target”); provided, however, that such indemnification of the SPAC by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the SPAC’s independent registered public accounting firm) or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per Offering Share or (ii) such lesser amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amounts of interest which may be withdrawn to pay taxes. For the avoidance of doubt, the Sponsor shall not be required to indemnify the SPAC pursuant to this paragraph 3 in the event of (i) any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account, and (ii) any claims under the SPAC’s indemnity of Goldman Sachs & Co. LLC and Citigroup Global Markets Inc., as the representatives of the several underwriters (each an “Underwriter” and collectively, the “Underwriters”) named in the underwriting agreement between the SPAC and the Underwriters dated as of June 29, 2020, against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the SPAC if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the SPAC in writing that it shall undertake such defense. For the avoidance of doubt, none of the SPAC’s officers or directors will indemnify the SPAC for claims by third parties, including, without limitation, claims by third party vendors and Targets.

4. The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters, the SPAC, and, prior to any valid termination of the Business Combination Agreement, the Company and the Charterhouse Parties, would be irreparably injured in the event of a breach by such Sponsor or Insider of its obligations under this Letter Agreement (with respect to the Underwriters, only such provisions as were contained in the Prior Letter Agreement) (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to seek injunctive relief, including to prevent breaches or threatened breaches of this Letter Agreement and to specifically enforce its terms, in addition to any other remedy that such party may have in law or in equity in the event of such breach.

5. (a) In the event that the Closing does not occur for any reason (including, without limitation, as a result of the valid termination of the Business Combination Agreement), the Sponsor and each Insider agrees that it shall not Transfer any Founder Shares (or Class A Common Shares issuable upon conversion thereof) until the earlier of (A) one year after the completion of the SPAC’s initial Business Combination and (B) subsequent to the completion of the SPAC’s initial Business Combination, (x) the date on which the SPAC completes a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Public Stockholders having the right to exchange their Class A Common Shares for cash, securities or other property or (y) if the last reported sale price of the Class A Common Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-day trading period commencing at least 150 days after the SPAC’s initial Business Combination (the “Standalone Founder Shares Lock-up Period”).

(b) In the event that the Closing does occur, the Sponsor and each Insider agrees that it shall not Transfer, or knowingly cause any other Person to Transfer on its behalf (A) any Founder Shares it owns or otherwise has a beneficial interest in or controls as at the time immediately prior to Closing until the earlier of (i) the one year anniversary of the Closing Date and (ii) the day following the trading date when the last reported sale price of the Class A Common Shares first equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-day trading period commencing at least 150 days after the Closing Date, subject to the clear market provisions in the Registration Rights Agreement and (B) any shares issued pursuant to the Sponsor PIPE Commitment if retained by the Sponsor or its Affiliates (but, for the avoidance of doubt, not if distributed to its employees and investment partners) for a period of 180 days after the Closing Date, subject to the clear market provisions in the Registration Rights Agreement, (such periods, the “Business Combination Agreement Lock-Up Periods” and, together with the Standalone Founder Shares Lock-Up Period, the “Lock-Up Periods”).

(c) Notwithstanding the provisions set forth in paragraphs 2 and 5(a) and (b), but subject to the provisions set forth in paragraph 5(d), upon the valid termination of the Business Combination Agreement, the following Transfers of the Founder Shares that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 5(c)), are permitted (a) to the SPAC’s officers or directors, any affiliates or family members of any of the SPAC’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor or any employee or partner of any such affiliate, (b) in the case of an individual, transfers by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of the SPAC’s Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the event of the SPAC’s liquidation prior to the SPAC’s completion of an initial Business Combination; (g) transfers by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement, as amended, upon dissolution of the Sponsor; (h) in the event of the SPAC’s completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of the Public Stockholders having the right to exchange their Class A Common Shares for cash, securities or other property subsequent to the SPAC’s completion of an initial Business Combination; or (i) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (a) through (h) above; provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter into a written agreement with the SPAC agreeing to be bound by the transfer restrictions and other applicable restrictions in this Letter Agreement.

(d) Vesting Provisions. The Sponsor and GS Acquisition Holdings II Employee Participation LLC agree that all of the Founder Shares as of the Closing (the “Vesting Shares”) shall be subject to the vesting and forfeiture provisions set forth in this paragraph 5(d). The Sponsor and GS Acquisition Holdings II Employee Participation LLC each agrees that it shall not Transfer, or knowingly cause any other Person to Transfer on its behalf, any unvested Founder Shares prior to the later of (x) the expiration of the Business Combination Agreement Lock-up Period and (y) the date such Founder Shares become vested pursuant to this paragraph 5(d).

(i) Vesting of Founder Shares.

(1) 33-1/3% of the Founder Shares shall vest at such time as a Stock Price Level equal to $12.00 (the “First Vesting Price”) is achieved on or before the date that is five years after the Closing Date.

(2) 33-1/3% of the Founder Shares shall vest at such time as a Stock Price Level equal to $14.00 (the “Second Vesting Price”) is achieved on or before the date that is five years after the Closing Date.

(3) 33-1/3% of the Founder Shares shall vest at such time as a Stock Price Level equal to $16.00 (the “Third Vesting Price”) is achieved on or before the date that is five years after the Closing Date.

(4) Founder Shares that do not vest in accordance with this paragraph 5(d)(i) on or before the date that is five years after the Closing Date will be forfeited immediately following the five-year anniversary of the Closing Date.

(ii) Acceleration of Vesting upon a Sale. In the event of a Sale prior to the fifth anniversary of the Closing Date or the vesting of unvested Founder Shares, vesting shall be accelerated or the unvested Founder Shares will be forfeited, as follows:

(1) With respect to the unvested Founder Shares that were eligible to vest pursuant to paragraph 5(d)(i)(1), as the case may be, if such Sale occurs on or before the date that is five years after the Closing Date, then (i) such Founder Shares will fully vest as of immediately prior to the closing of such Sale only if the per share price of the Class A Common Shares paid or implied in such Sale equals or exceeds the First Vesting Price and (ii) no portion of such Founder Shares or Class A Common Shares will vest in connection with such Sale if the per share price of the Class A Common Shares paid or implied in such Sale is less than the First Vesting Price.

(2) With respect to the unvested Founder Shares that were eligible to vest pursuant to paragraph 5(d)(i)(2), as the case may be, if such Sale occurs on or before the date that is five years after the Closing Date, then (i) such Founder Shares will fully vest as of immediately prior to the closing of such Sale only if the per share price of the Class A Common Shares paid or implied in such Sale equals or exceeds the Second Vesting Price and (ii) no portion of such Founder Shares or Class A Common Shares will vest in connection with such Sale if the per share price of the Class A Common Shares paid or implied in such Sale is less than the Second Vesting Price.

(3) With respect to the unvested Founder Shares that were eligible to vest pursuant to paragraph 5(d)(i)(3), as the case may be, if such Sale occurs on or before the date that is five years after the Closing Date, then (i) such Founder Shares will fully vest as of immediately prior to the closing of such Sale only if the per share price of the Class A Common Shares paid or implied in such Sale equals or exceeds the Third Vesting Price and (ii) no portion of such Founder Shares or Class A Common Shares will vest in connection with such Sale if the per share price of the Class A Common Shares paid or implied in such Sale is less than the Third Vesting Price.

(4) Unvested Founder Shares that do not vest in accordance with this paragraph 5(d)(ii) upon the occurrence of a Sale will be forfeited immediately prior to the closing of such Sale and in accordance with paragraph 5(d)(iii).

(5) For purposes of this paragraph 5(d)(ii), “Sale” means (A) a purchase, sale, exchange, business combination or other transaction (including a merger or consolidation of SPAC with or into any other corporation or other entity) in which the equity securities of SPAC, its successor or the surviving entity of such business combination or other transaction are not registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or listed or quoted for trading on a national securities exchange or (B) a sale, lease, exchange or other transfer in one transaction or a series of related transactions of all or substantially all of SPAC’s assets. For avoidance of doubt, following a transaction or business combination that is not a “Sale” hereunder, including a transaction or business combination in which the equity securities of the surviving entity of such business combination or other transaction are registered under the Exchange Act and listed or quoted for trading on a national securities exchange, the equitable adjustment provisions of paragraph 20 shall apply, including, without limitation, to performance vesting criteria.

(iii) Voting. Holders of Founder Shares subject to the vesting provisions of this paragraph 5(d) shall be entitled to vote such Founder Shares and receive dividends and other distributions with respect to such Founder Shares prior to vesting; provided, that dividends and other distributions with respect to Founder Shares that are subject to vesting pursuant to paragraph 5(d)(i) shall be set aside by the SPAC and shall only be paid to such holders upon the vesting of such Founder Shares; for the avoidance of doubt, (i) such dividends and other distributions shall be paid only on the portion of the unvested Founder Shares that vest and (ii) if any dividends or other distributions with respect to Founder Shares that are subject to vesting pursuant to paragraph 5(d)(i) are set aside and such Founder Shares are subsequently forfeited, such set aside dividends or distributions shall become the property of the SPAC; provided further, that (i) the amount of any dividends and other distributions with respect to the unvested Founder Shares and set aside by SPAC pursuant to this paragraph 5(d)(iii) shall not be reported as taxable income (on IRS Form 1099 or otherwise) to the holders of Founder Shares unless and until such dividends are paid in cash or in kind (which, for the avoidance of doubt, for purposes of this Letter Agreement, shall not include any transaction subject to paragraph 20 hereof), as the case may be and (ii) the parties to this Letter Agreement shall not take any position inconsistent with such reporting except to the extent otherwise required by a “determination” as defined in Section 1313 of the Code. References in this paragraph 5(d)(iii) to the Code shall include references to any similar or analogous provisions of state or local law.

(iv) Forfeiture. Founder Shares or Class A Common Shares that are forfeited pursuant to paragraph 5(d)(i) or 5(d)(ii) shall be promptly transferred by Sponsor to the SPAC, without any consideration for such Transfer, and cancelled.

(v) Stock Price Level. For purposes of this paragraph 5(d), the applicable “Stock Price Level” will be considered achieved only when the volume weighted average price per share of Class A Common Shares on the New York Stock Exchange, or such other securities exchange where the Class A Common Shares are listed or quoted, equals or exceeds the applicable threshold for any 20 trading days during a 30 consecutive trading day period. The Stock Price Levels (and the share price levels in a Sale in paragraph 5(d)(ii)) will be equitably adjusted on account of any stock split, reverse stock split or similar equity restructuring transaction.

(e) Waiver of Conversion Ratio Adjustment.

(1) (A) Section 4.3(b)(i) of the Charter provides that each share of Class B Common Stock (as defined therein) shall automatically convert into one Class A Common Share (the “Initial Conversion Ratio”) at the time of closing of the SPAC’s initial Business Combination, and (B) Section 4.3(b)(ii) of the Charter provides that the Initial Conversion Ratio shall be adjusted (the “Adjustment”) in the event that additional Class A Common Shares or equity-linked securities (as defined therein) are issued or deemed issued in excess of the amounts offered in the IPO and in relation to the closing of the initial Business Combination, such that the Sponsor and the Insiders shall continue to own 20% of the issued and outstanding Shares after giving effect to such issuance.

(2) As of, and conditioned upon the Closing, the Sponsor and each Insider hereby irrevocably relinquishes and waives any and all rights the Sponsor and each Insider has or will have under Section 4.3(b)(ii) of the Charter to receive Class A Common Shares in excess of the number issuable at the Initial Conversion Ratio upon conversion of the existing Founder Shares held by it in connection with the Closing as a result of any Adjustment, and, as a result, the Founder Shares shall convert into Class A Common Shares (or such equivalent security) at Closing on a one-for-one basis.

6. The Sponsor and each Insider represents and warrants that it has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider represents that such Insider’s biographical information furnished to the SPAC, if any (including any such information included in the Prospectus), is true and accurate in all respects and does not omit any material information with respect to such Insider’s background. The Sponsor and each Insider’s questionnaire furnished to the SPAC, if any, is true and accurate in all respects.

7. Except as disclosed on Schedule 5.17 (Brokers’ Fees) of the Business Combination Agreement, neither the Sponsor nor any Insider nor any Affiliate of the Sponsor or any Insider, nor any director or officer of the SPAC, shall receive from the SPAC any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the SPAC’s initial Business Combination (regardless of the type of transaction that it is).

8.
