(2)Each of the Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any roadshow or any Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus, or any roadshow or any Testing-the-Waters Communication, in reliance upon and in conformity with written information furnished to the Company by such Selling Stockholder pursuant to Item 7 of Form S-3 expressly for use therein (the “Selling Stockholder Information”); and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that such Selling Stockholder shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus in reliance upon and in conformity with the Underwriter Information.

(3)The Underwriter will indemnify and hold harmless the Company and each Selling Stockholder against any losses, claims, damages or liabilities to which the Company or such Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow, or any Testing-the-Waters Communication, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any roadshow, or any Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information; and will reimburse the Company and each Selling Stockholder for any legal or other expenses reasonably incurred by the Company or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred. As used in this Agreement with respect to an Underwriter and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such Underwriter expressly for use therein; it being understood and agreed upon that the only such information furnished by the Underwriter consists of the following information in the Prospectus: the concession and reallowance figures appearing in the fourth paragraph under the caption “Underwriting”, and the information contained in the twelfth paragraph under the caption “Underwriting”.

(4)Promptly after receipt by an indemnified party under subsection (a), (b), or (c) of this Section 9 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 9. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(5)If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders on the one hand or the Underwriter on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, each of the Selling Stockholders and the

Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(6)The obligations of the Company and the Selling Stockholders under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of each Underwriter and each person, if any, who controls the Underwriter within the meaning of the Act and each broker-dealer or other affiliate of the Underwriter; and the obligations of the Underwriter under this Section 9 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Act.

10.(a) If the Underwriter shall default in its obligation to purchase the Shares that it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by the Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Stockholders that you have so arranged for the purchase of such Shares, or the Company or a Selling Stockholder notifies you that it has so arranged for the purchase of such Shares, you or the Company or the Selling Stockholders shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders, except for the expenses to be borne by the Company, the Selling Stockholders and the Underwriter as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11.The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, the Selling Stockholders and the Underwriter, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter or any director, officer, employee, affiliate or controlling person of the Underwriter, or the Company, or any of the Selling Stockholders, or any officer or director or controlling person of the Company, or any controlling person of any Selling Stockholder, and shall survive delivery of and payment for the Shares.

12.If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Selling Stockholders shall then be under any liability to the Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Selling Stockholders as provided herein, or the Underwriter declines to purchase the Shares for any reason permitted under this Agreement: (x) if because of any failure or refusal on the part of any of the Selling Stockholders to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any of the Selling Stockholders shall be unable to perform its obligations under this Agreement, each of the Selling Stockholders pro rata (based on the number of Shares to be sold by such Selling Stockholder) hereunder will reimburse the Underwriter for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Shares not so delivered (the “Termination Expenses”); or (y) otherwise, the Company will reimburse the Underwriter for the Termination Expenses; but, in each case, the Company and the Selling Stockholders shall then be under no further liability to the Underwriter except as provided in Sections 7 and 9 hereof.

13.In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriter is required to obtain, verify and record information that identifies their clients, including the Company and the Selling Stockholders, which information may include the name and address of their clients, as well as other information that will allow the Underwriter to properly identify their clients.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriter shall be delivered or sent by mail, telex or facsimile transmission to Citigroup Global Markets Inc., 388 Greenwich Street, New York, NY 10013, Attention: General Counsel, Fax: 646 ###-###-####; if to any Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission to The Charterhouse Holders, 6th Floor, Belgrave House, 76 Buckingham Palace Road, London, SW1W 9TQ, United Kingdom, Attention: Christopher Warren, Thomas Patrick, E-mail: chris.warren@charterhouse.co.uk; tom.patrick@charterhouse.co.uk, with a copy (which shall not constitute notice) to Freshfields Bruckhaus Deringer US LLP, 601 Lexington Avenue, 31st Floor, New York, New York 10019, Attention: Valerie Ford Jacob, E-mail: valerie.jacob@freshfields.com; if to the Company shall be delivered or sent by mail to Mirion Technologies, Inc., 1218 Menlo Drive, Atlanta, Georgia 30318, Attention: Brian Schopfer and Emmanuelle Lee, and if to any stockholder that has delivered a lock-up letter described in Section 8(j) hereof shall be delivered or sent by mail to his or her respective address provided in Schedule IV hereto or such other address as such stockholder provides in writing to the Company; provided, however, that any notice to an Underwriter pursuant to Section 9(d) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters' Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company or the Selling Stockholders by you on request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14.This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriter, the Company and the Selling Stockholders and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company, any Selling Stockholder or the Underwriter, or any director, officer, employee, or affiliate of the Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from the Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15.Time shall be of the essence of this Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

16.The Company and the Selling Stockholders acknowledge and agree that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm's-length commercial transaction between the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other, (ii) in connection therewith and with the process leading to such transaction the Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or any Selling Stockholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or any Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or any Selling Stockholder on other matters) or any other obligation to the Company or any Selling Stockholder except the obligations expressly set forth in this Agreement, (iv) the Company and each Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate, and

(v) none of the activities of the Underwriter in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriter with respect to any entity or natural person. The Company and each Selling Stockholder agrees that it will not claim that the Underwriter, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or any Selling Stockholder, in connection with such transaction or the process leading thereto.

17.This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Selling Stockholders and the Underwriter, or any of them, with respect to the subject matter hereof.

18.This Agreement and any transaction contemplated by this Agreement and any claim, controversy or dispute arising under or related thereto shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflict of laws that would result in the application of any other law than the laws of the State of New York. The Company and each Selling Stockholder agree that any suit or proceeding arising in respect of this Agreement or any transaction contemplated by this Agreement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company and each Selling Stockholder agree to submit to the jurisdiction of, and to venue in, such courts.

19.The Company, each Selling Stockholder and the Underwriter hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, "tax structure" is limited to any facts that may be relevant to that treatment.

(18)in the case of a proposed Transfer of Lock-Up Securities pursuant to clause (j) above, prior to any such Transfer, the undersigned shall have received written consent to the Transfer from the Chief Legal Officer of the Company; provided further, that such consent shall be withheld by such person (and the Company shall ensure that such consent is withheld) to the extent (but only to the extent) that the Transfer would result in more than 50,000 Lock-Up Securities (in aggregate, when considering all prior Transfers pursuant to such provision) being Transferred pursuant to such provision during the Lock-Up Period.

Notwithstanding any other provision hereof, the undersigned may not, within the Lock-Up Period, make any demand for or exercise any right with respect to the registration of any Lock-Up Securities that is publicly disclosed (or required to be publicly disclosed), including, without limitation, any right which he, she or it may have, either individually or collectively with one or more other persons, pursuant to that certain Amended and Restated Registration Rights Agreement, dated as of October 20, 2021 and as it may be further amended, restated or otherwise modified, by and among the Company and the other parties thereto (the “Registration Rights Agreement”).

The undersigned further agrees that the foregoing provisions shall be equally applicable to any Shares the undersigned may purchase in the Public Offering.

    The undersigned acknowledges and agrees that the Underwriter has not made any recommendation or provided any investment or other advice to the undersigned with respect to this Lock-Up Agreement or the subject matter hereof, and the undersigned has consulted its own legal, accounting, financial, regulatory, tax and other advisors with respect to this Lock-Up Agreement and the subject matter hereof to the extent the undersigned has deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriter may have provided or hereafter provide to the undersigned in connection with the Public Offering a Form CRS and/or certain other disclosures as contemplated by Regulation Best Interest, the Underwriter has not made and is not making a recommendation to the undersigned to enter into this Lock-Up Agreement or to transfer, sell or dispose of, or to refrain from transferring, selling or disposing of, any shares of Common Stock or any Paired Interests, and nothing set forth in such disclosures or herein is intended to suggest that the Underwriter is making such a recommendation.

    This Lock-Up Agreement shall automatically terminate and the undersigned shall be released from all of his, her or its obligations hereunder upon the earlier of (a) the date on which the Underwriting Agreement is terminated for any reason (other than the provisions thereof that survive termination) prior to payment for and delivery of the Shares to be sold thereunder (other than pursuant to the Underwriter‘s option thereunder, if any, to purchase additional Shares), (b) the date on which the Charterhouse Holders (as defined in the Registration Rights Agreement) or the Company notifies the Underwriter in writing, and prior to the execution of the Underwriting Agreement, that it does not intend to proceed with the Public Offering, and (c) the date which is 30 days after the date hereof, in the event that the Underwriting Agreement has not been executed by such date.

    In the event that, during the Lock-Up Period, the Underwriter releases or waives, in full or in part, any prohibition set forth in this Lock-Up Agreement in respect of Lock-Up Securities held by any other Company securities holder (a “Triggering Release”), the same percentage of Lock-Up Securities of the undersigned subject to this Lock-up Agreement as the percentage of Lock-Up Securities being released in the Triggering Release represents with respect to the Lock-Up Securities held directly or indirectly by such other Company securities holder (calculated as a percentage of the total outstanding Lock-Up Securities subject to this Lock-Up Agreement held directly or indirectly by such holder) at the time of effectiveness of the Triggering Release shall be automatically and concurrently released from this Lock-Up Agreement to the same extent; provided, however, that if such Triggering Release is effected in connection with an underwritten public offering that is wholly or partially a secondary offering of Class A Common Stock (an “Underwritten Offering”), such Lock-Up Securities shall only be

released to the extent necessary to permit the offer, transfer and sale of such Lock-Up Securities in the Underwritten Offering (including the execution and delivery of the underwriting agreement with respect thereto), and any Lock-Up Securities subject to this Lock-Up Agreement that are not actually sold in the Underwritten Offering will not be deemed released from the restrictions set forth in this Lock-Up Agreement. Notwithstanding the foregoing, the provisions of this paragraph will not apply (1) if the release or waiver is effected solely to permit a transfer not involving a disposition for value and the transferee agrees in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of transfer, or (2) if the release or waiver is granted by the Underwriter in its sole judgment that a record or beneficial owner of any Lock-Up Securities should be granted an early release from a lock-up agreement due to circumstances of an emergency or hardship.

The undersigned understands that the Company and the Underwriter are relying upon this Lock-Up Agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. The undersigned hereby represents and warrants that the undersigned has legal capacity and full power and authority to enter into this Lock-Up Agreement. This Lock-Up Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflict of laws that would result in the application of any law other than the laws of the State of New York. This Lock-Up Agreement may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com or www.echosign.com) or other transmission method, and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

Very truly yours,
