9.(a) The Company will indemnify and hold harmless [the/each] Underwriter, against any losses, claims, damages or liabilities, joint or several, to which [the/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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “roadshow” as defined in Rule 433(h) under the Act conducted in connection with the offering of the Shares hereunder (a “roadshow”), any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the Act in connection with the offering of the Shares hereunder 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, and will reimburse [the/each] Underwriter for any legal or other expenses reasonably incurred by [the/such] Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any Testing-the-Waters Communication, in reliance upon and in conformity with the Underwriter Information.

(b)The Selling Stockholder will indemnify and hold harmless [the/each] Underwriter, against any losses, claims, damages or liabilities, joint or several, to which [the/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, 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 the Selling Stockholder Information; and will reimburse [the/each] Underwriter for any legal or other expenses reasonably incurred by [the/such] Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the 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, 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; provided, further, that the aggregate liability of the Selling Stockholder pursuant to this subsection (b) shall be limited to an amount equal to the proceeds (net of underwriting discounts and commissions but without deducting expenses) received by the Selling Stockholder for the Shares sold under this Agreement.

(c)[The/Each] Underwriter[, severally and not jointly,] will indemnify and hold harmless the Company and the Selling Stockholder against any losses, claims, damages or liabilities to which the Company or the 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, 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, 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 the Selling Stockholder for any legal or other expenses reasonably incurred by the Company or the 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 through the Representative[s] expressly for use therein; it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the sixth paragraph under the caption “Underwriting”, and the information contained in the fourteenth, fifteenth and sixteenth paragraphs under the caption “Underwriting”.

(d)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 reasonably 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.

(e)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 Stockholder on the one hand and the Underwriter[s] 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 Stockholder on the one hand and the Underwriter[s] 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 Stockholder on the one hand and the Underwriter[s] 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 Stockholder bear to the total underwriting discounts and commissions received by the Underwriter[s], 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 Stockholder on the one hand or the Underwriter[s] on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. [The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e).] [To include if multiple Underwriters.] 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) (i) 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 and (ii) the aggregate amount the Selling Stockholder may be required to contribute pursuant to this subsection (b) shall be limited to the amount, if any by which the proceeds (net of underwriting discounts and

commissions but without deducting expenses) received by the Selling Stockholder for the Shares sold under this Agreement exceeds the amount of any damages which the Selling Stockholder 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. [The Underwriters' obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint]. [To include if multiple Underwriters.]

(f)The obligations of the Company and the Selling Stockholder under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of [the/each] Underwriter and each person, if any, who controls [the/any] Underwriter within the meaning of the Act and each broker-dealer or other affiliate of [the/any] Underwriter; and the obligations of the Underwriter[s] under this Section 9 shall be in addition to any liability which the respective Underwriter[s] may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and the Selling Stockholder and to each person, if any, who controls the Company or the Selling Stockholder within the meaning of the Act.

10.[(a) If any Underwriter shall default in its obligation to purchase the Shares that it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties reasonably satisfactory to the Company and the Selling Stockholder to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of all of such Shares, then the Company and the Selling Stockholder shall be entitled to a further period of thirty-six hours within which to procure another party or other parties mutually and reasonably agreeable to them and satisfactory to you to purchase any such Shares that remain on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Stockholder that you have so arranged for the purchase of such Shares, or the Company and the Selling Stockholder notify you that they have so arranged for the purchase of such Shares, you or the Company or the Selling Stockholder shall have the right to postpone such 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] as provided in subsection [(a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Selling Stockholder shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder)

of the Shares of such defaulting Underwriter [or Underwriters] for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter [or Underwriters] 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 to be purchased at such Time of Delivery, or if the Selling Stockholder shall not exercise the right described in subsection (b) above to require non-defaulting Underwriter[s] to purchase Shares of a defaulting Underwriter [or Underwriters], then this Agreement (or, with respect to a Second Time of Delivery, the obligations of the Underwriter[s] to purchase and of the Selling Stockholder to sell the Optional Shares shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except for the expenses to be borne by the Company, the Selling Stockholder and the Underwriter[s] 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.] [To include if multiple Underwriters.]

11.The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholder and the [several] Underwriter[s], 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/any] Underwriter or any controlling person of [the/any] Underwriter, or the Company, or the Selling Stockholder, or any officer or director or controlling person of the Company, or any controlling person of the 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 Stockholder shall then be under any liability to [the/any] 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 Stockholder as provided herein, or the Underwriter[s] decline to purchase the Shares for any reason permitted under this Agreement, the Selling Stockholder will reimburse the Underwriter[s] through you for all out-of-pocket expenses approved in writing by you, including reasonably incurred and documented fees and disbursements of counsel, reasonably incurred and documented by the Underwriter[s] in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Stockholder shall then be under no further liability to [the/any] Underwriter except as provided in Sections 7 and 9 hereof.

13.In all dealings hereunder, the Representative[s] shall act on behalf of [each of] the Underwriter[s], and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of [the/any] Underwriter made or given by the Representative[s] [jointly].

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[s] are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Stockholder, which information may include the name and address of their respective clients, as

well as other information that will allow the Underwriter[s] to properly identify their respective clients.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriter[s] shall be delivered or sent by mail, electronic mail, telex or facsimile transmission to [Name of Underwriter[s]], [Address[es]], Attention: [Underwriter Contact[s]]; if to the Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission to [▇▇▇▇▇▇▇▇ US Holding, LLC's Contact[s]]; if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth on the cover of the Registration Statement, Attention: Executive Vice President, General Counsel and Secretary; and if to any stockholder that has delivered a lock-up letter described in Section 8(k) hereof shall be delivered or sent by mail to his or her respective address provided in Schedule III 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 [Underwriter’s/Underwriters'] Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company or the Selling Stockholder by you on request; provided further that notices under subsection 5(d) shall be in writing, and if to the Underwriter[s] shall be delivered or sent by mail, telex or facsimile transmission to you as you at [Name of Underwriter[s]], [Address[es]], Attention: [Underwriter Contact[s]]. 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[s], the Company and the Selling Stockholder 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, the Selling Stockholder or [the/any] 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/any] 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 Stockholder 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 Stockholder, on the one hand, and the [several] Underwriter[s], on the other, (ii) in connection therewith and with the process leading to such transaction [the/each] Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Selling Stockholder, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether [the/such] Underwriter has advised or is currently advising the Company or the Selling Stockholder on other matters) or any other obligation to the Company or the Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) the Company and the Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company and the Selling Stockholder agree that it will not claim that the Underwriter[s][, or any of them,] has rendered advisory services of any nature or respect, or

owes a fiduciary or similar duty to the Company or the 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 Stockholder and the Underwriter[s], 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 the 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 the Selling Stockholder agree to submit to the jurisdiction of, and to venue in, such courts.

19.The Company, the Selling Stockholder and [each of] the Underwriter[s] 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.

20.This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

21.Counterparts may be delivered via facsimile, electronic mail (including any electronic signature complying with the New York Electronic Signatures and Records Act (N.Y. State Tech. §§ 301-309), as amended from time to time, or covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., ▇▇▇.▇▇▇▇▇▇▇▇.▇▇▇) 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.

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.

23.Recognition of the U.S. Special Resolution Regimes.

Re: ▇▇▇▇▇▇▇▇ DRS, Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned, a stockholder and/or an officer and/or a director, as applicable, of ▇▇▇▇▇▇▇▇ DRS, Inc., a Delaware corporation (the “Company”), understands that [Name[s] of Underwriter[s]] as representative[s] (the “Representative[s]”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the [several] Underwriter[s] named in Schedule I to such agreement ([collectively,] the “Underwriter[s]”), with the Company and ▇▇▇▇▇▇▇▇ US Holding, LLC (the “Selling Stockholder[s]”), providing for a follow-on public offering (“Public Offering”) of shares of the common stock, par value $0.01 per share, of the Company (the “Shares”), pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriter[s] to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 90 days after the date (the “Public Offering Date”) set forth on the final prospectus used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any Shares of the Company, or any options or warrants to purchase any Shares of the Company, or any securities convertible into, exchangeable for or that represent the right to receive Shares of the Company (such options, warrants or other securities, collectively, “Derivative Instruments”), including without limitation any such Shares or Derivative Instruments now owned or hereafter acquired by the undersigned (collectively, the “Undersigned’s Shares”), (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any Undersigned’s Shares, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Shares or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or

Annex II-1

directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of doubt, the undersigned agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Shares the undersigned may purchase in the Public Offering.

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended), other than a natural person, entity or “group” (as described above) that has executed a Lock-Up Agreement in substantially the same form as this Lock-Up Agreement=, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.

Notwithstanding the foregoing, the undersigned may (a) Transfer or otherwise dispose of the Undersigned’s Shares:

(i)as a bona fide gift or gifts or as a charitable contribution; provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein; and provided further that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(ii)to any immediate family member (as defined below) of the undersigned or to any trust for the direct or indirect benefit of the undersigned or of any member of the immediate family of the undersigned; provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(iii)to any beneficiary of or estate of a beneficiary of the undersigned pursuant to a trust, will, other testamentary document or intestate succession or applicable laws of descent, provided that the beneficiary or the estate of a beneficiary thereof agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transaction shall not involve a disposition for value and that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(iv)to a partnership, limited liability company or other entity of which the undersigned and the immediate family of the undersigned are the legal and beneficial owner of all the outstanding equity securities or similar interests, provided that such partnership, limited liability company or other entity agrees to be bound in writing by the restrictions set forth herein, and provided further that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in

Annex II-2

beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(v)by operation of law, pursuant to a qualified domestic order of a court (including a divorce settlement, divorce decree or separation agreement), provided that the transferee or transferees thereof agree to be bound in writing by the restrictions set forth herein, and provided further that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(vi)in transactions relating to shares of Common Stock in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of such shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period;

(vii)by (A) transfers of shares of Common Stock to the Company upon the “net” or “cashless” exercise of stock options or other equity awards granted pursuant to equity incentive plans described in the Registration Statement or (B) forfeitures of shares of Common Stock to the Company to satisfy tax withholding requirements of the undersigned or the Company upon the vesting, during the Lock-Up Period, of equity based awards granted under equity incentive plans or pursuant to other stock purchase arrangements, in each case described in the Registration Statement; provided that the underlying shares of Common Stock shall continue to be subject to the restrictions on transfer set forth in this Lock Up Agreement, and provided further that, if required, any public report or filing under Section 16(a) of the Exchange Act shall indicate in the footnotes thereto the nature of the transaction;

(viii)pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s capital stock after the consummation of the Public Offering, involving a change of control of the Company, or group of persons, shall become, after the closing of the transaction, the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of total voting power of the voting securities of the Company), provided that in the event that such tender offer, merger, consolidation or other such transaction is not completed, the undersigned’s shares of Common Stock shall remain subject to the provisions of this Lock-Up Agreement;

(ix)to the Company in connection with the repurchase by the Company from the undersigned of shares of Common Stock of the Company or Derivative Instruments pursuant to a repurchase right arising upon the termination of the undersigned’s employment with the Company; provided that such repurchase right is pursuant to contractual agreements with the Company; and provided further that, if required, any public report or filing under Section 16(a) of the Exchange Act shall indicate in the footnotes thereto the nature of the transaction;

(x)if the undersigned is a corporation, partnership, limited liability company or other business entity, by (A) distribution of shares of Common Stock or any Derivative

Annex II-3

Instrument to limited partners, general partners, members, stockholders, holders of similar interests of the undersigned (or in each case its nominee or custodian) or to any investment holding company controlled or managed by the undersigned or (B) transfers of shares of Common Stock or any Derivative Instrument to affiliates (as defined in Rule 405 of the Securities Act of 1933, as amended) or other entities controlled or managed by the undersigned or any of its affiliates (other than the Company and its subsidiaries); provided that each distributee and transferee agrees to be bound in writing by the restrictions set forth herein, and provided further that no filing under Section 16(a) of the Exchange Act (other than a Form 5, which shall not be filed on or prior to the date that is 90 days after the date set forth on the final prospectus used to sell the Shares), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Lock-Up Period; or

(xi)with the prior written consent of [the/each of the [Number]] Representative[s] on behalf of the Underwriter[s].

(b)enter into a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act relating to the transfer, sale or other disposition of securities of the undersigned, if then permitted by the Company, provided that (i) the securities subject to the plan may not be sold during the Lock-Up Period (except to the extent otherwise allowed pursuant to clause (a) above) and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Shares may be made under such plan during the Lock-Up Period.

For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin, and “change of control” shall mean any bona fide third-party tender offer, merger, consolidation or other similar transaction approved by the board of directors of the Company the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company, shall become, after the closing of the transaction, the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of total voting power of the voting stock of the Company. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the capital stock of the Company to any wholly-owned subsidiary of such corporation or of another corporation that wholly owns the undersigned; provided, however, that in any such case, it shall be a condition to the Transfer that the transferee execute an agreement stating that the transferee is receiving and holding such capital stock subject to the provisions of this Agreement and there shall be no further Transfer of such capital stock except in accordance with this Agreement, and provided further that any such transfer shall not involve a disposition for value. The undersigned now has, and, except as contemplated above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. [In addition, the undersigned agrees that, without the prior written consent of the Representative[s] on behalf of the Underwriter[s], it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of its Shares or any security convertible into or exercisable or exchangeable for Shares, provided that it may, without the prior written consent of [any of] the Representative[s] on behalf of the Underwriter[s], make any demand for the sale of, or request to sell, all or part of its remaining Shares pursuant to the Registration Rights Agreement, dated as of November 28, 2022, between the Company and the Selling Stockholder as long as no public announcement of any such demand, request or

Annex II-4

proposed offering and sale of Shares is made and no registration statement is filed with the Commission.]1 The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the Transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

The undersigned acknowledges and agrees that the Underwriter[s] [has/have] not provided any recommendation or investment advice nor [has/have] the Underwriter[s] solicited any action from the undersigned with respect to the Public Offering of the Shares and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriter[s] may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the Public Offering, the Underwriter[s] [is/are] not making a recommendation to you to participate in the Public Offering or sell any Shares at the price determined in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that [any/the] Underwriter is making such a recommendation.

The undersigned understands that the Company and the Underwriter[s] are relying upon this Lock-Up Agreement in proceeding toward consummation of the Public Offering.

The undersigned agrees that this Lock-Up Agreement may be signed electronically.

This Lock-Up Agreement and any claim, controversy or dispute arising under or related to this Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York.

It is understood that this Lock-Up Agreement shall immediately be terminated and the undersigned shall be released from all obligations under this Lock-Up Agreement if (i) the Company notifies the Representatives, in writing, prior to the execution of the Underwriting Agreement, that it has determined not to proceed with the Public Offering, (ii) the Company files an application with the SEC to withdraw the registration statement related to the Public Offering, (iii) the Underwriting Agreement is executed but is then terminated (other than the provisions thereof which survive termination) prior to payment for and delivery of the shares to be sold thereunder, or (iv) the Public Offering shall not have been completed by [Date], in the event the Underwriting Agreement has not been executed by such date.
