(a) The Company Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and their respective officers, directors, employees and selling agents (including any affiliate of an Underwriter involved on behalf of the Underwriter in the distribution process for the Shares) 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, the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” (in the case of either an Issuer Free Writing Prospectus or such “issuer information,” taken together with the Pricing Prospectus) filed or required to be filed pursuant to Rule 433(d) under the Act or any road show as defined in Rule 433(h) of the Act (a “Road Show”), 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 the case of the Basic Prospectus, the Preliminary Prospectus, the Pricing Prospectus, the Prospectus, or any amendment or supplement thereto, and any Issuer Free Writing Prospectus, in the light of the circumstances under which they were made), 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 the Company Parties shall not be liable to any Underwriter 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 written information furnished to the Company by any Underwriter through the Representative expressly for use therein.

(b) Each Selling Stockholder, severally and not jointly, will indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and their respective officers, directors, employees and selling agents (including any affiliate of an Underwriter involved on behalf of the Underwriter in the distribution process for the Shares) against any losses, claims, damages or liabilities 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 (taken together with the Pricing Prospectus) or any Road Show, 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 the case of the Basic Prospectus, the Preliminary Prospectus, the Pricing Prospectus, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in the light of the circumstances under which they were made), 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, any Issuer Free Writing Prospectus or any Road Show, in reliance upon and in conformity with the Selling Stockholder Information relating to such Selling Stockholder; and will reimburse each Underwriter for any

24

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, any Issuer Free Writing Prospectus or any Road Show, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use therein; provided, further, that the liability of a Selling Stockholder pursuant to this subsection (b) shall not exceed the product of (i) the number of Shares sold by such Selling Stockholder and (ii) the per share net proceeds to the Selling Stockholder (after deducting underwriting discounts and commissions but before any other applicable expenses) as forth in the Pricing Prospectus.

(c) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company Parties, each Selling Stockholder and each person, if any, who controls any Company Party or such Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and their respective officers, directors and employees against any losses, claims, damages or liabilities to which the Company Parties 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, any Issuer Free Writing Prospectus (taken together with the Pricing Prospectus) or any Road Show, 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 the case of the Basic Prospectus, the Preliminary Prospectus, the Pricing Prospectus, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in the light of the circumstances under which they were made), 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, any Issuer Free Writing Prospectus or any Road Show, in reliance upon and in conformity with written information furnished to the Company Parties by such Underwriter through the Representative expressly for use therein; and will reimburse the Company Parties and any Selling Stockholder for any legal or other expenses reasonably incurred by the Company Parties or such Selling Stockholder or such in connection with investigating or defending any such action or claim as such expenses are incurred. The Company Parties and each of the Selling Stockholders acknowledge that the following statements constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion 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 or any Road Show (the “Underwriter Information”): the names of the Underwriters and the statements in the fourth, seventh, thirteenth, fourteenth, fifteenth and seventeenth paragraphs under the heading “Underwriting” contained in the Pricing Prospectus.

25

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) of this Section 11 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; but the omission so to notify the indemnifying party shall not relieve it from any liability hereunder to the extent it is not materially prejudiced (through the forfeiture of substantive rights and defenses) as a result thereof and in any event shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. 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. To the extent that an indemnifying party does not assume the defense of any such action, it is understood that the indemnifying party or parties shall not, in connection with any one action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties (except to the extent that local counsel (in addition to any regular counsel) is required to effectively defend against any such action or proceeding); provided that the fees and expenses of such separate firm of attorneys and any local counsel shall be reasonably incurred. 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. No indemnifying party shall be liable for any settlement of any action effected without its prior written consent.

(e) If the indemnification provided for in this Section 11 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 Parties and the Selling Stockholders on the one hand and the Underwriters 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 or if the indemnified party failed to give the notice required under subsection (d) above, 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 respective relative fault of the Company

26

Parties, Selling Stockholders, and the Underwriters 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 Selling Stockholders and the Underwriters from the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering (before deducting expenses) received by the Selling Stockholders from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover 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 Parties, the Selling Stockholders, or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company Parties, the Selling Stockholders 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). 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.

The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint; provided, further, that the liability of any Selling Stockholder pursuant to this subsection (e) shall not exceed the product of (i) the number of Shares sold by such Selling Stockholder and (ii) the per share net proceeds to such Selling Stockholder (after deducting underwriting discounts and commissions) as set forth in the Pricing Prospectus.

(f) The obligations of the Company Parties and the Selling Stockholders under this Section 11 shall be in addition to any liability which the Company Parties and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 11 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of any Company Party and to each person, if any, who controls any Company Party or any Selling Stockholder within the meaning of the Act.

27

12. If any Underwriter shall default in its obligation to purchase the Shares that it has agreed to purchase hereunder at a Time of Delivery, then this Agreement (or with respect to a Second Time of Delivery, the obligations of the Underwriters to purchase and of the Selling Stockholders to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, any Selling Stockholder or any Company Party, except for the expenses to be borne by the Company Parties, the Underwriters and the Selling Stockholders as provided in Section 9 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

13. The respective indemnities, agreements, representations, warranties and other statements of the Company Parties, the Selling Stockholders and the several Underwriters, 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 any Underwriter or any controlling person of any Underwriter, Company Party or Selling Stockholder or any officer or director or controlling person of such Company Party or Selling Stockholder, and shall survive delivery of and payment for the Shares.

14. If this Agreement shall be terminated pursuant to Section 12 hereof, neither the Company Parties nor any Selling Stockholder shall be under any liability to any Underwriter except as provided in Sections 9 and 11 hereof; but, if for any other reason any Shares are not delivered by or on behalf of any Selling Stockholder as provided herein, (x) the Company Parties, jointly and severally, or (y) if such failure to deliver any Shares arises from the breach of a representation, warranty or covenant by any Selling Stockholder, such Selling Stockholder or Selling Stockholders pro rata (based on the number of Shares to be sold by such Selling Stockholder or Selling Stockholders hereunder) will reimburse the Underwriters through the Representative for all out-of-pocket expenses approved in writing by the Representative, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but neither any Company Party nor any Selling Stockholder shall then be under any further liability to any Underwriter except as provided in Sections 9 and 11 hereof.

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

16. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail or facsimile transmission to the Representative in care of Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Registration Department; if to the Company Parties shall be delivered or sent by email to the address of the Company set forth on the cover of the Registration Statement, Attention: Mark G. Whittenburg, General Counsel and Secretary (email: ***@***), copy to Paul M. Rodel (email: ***@***) and if to any Selling Stockholder or any other stockholder that has

28

delivered a lock-up letter described in Section 10(j) hereof, shall be delivered or sent by mail or facsimile transmission to counsel therefor at its address as set forth in Schedule II hereto or such other address provided in writing to the Company thereby; provided, however, that any notice to an Underwriter pursuant to Section 11(d) hereof shall be delivered or sent by mail facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, which address will be supplied to the Company and the Selling Stockholders by the Representative on request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

17. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company Parties and the Selling Stockholders and, to the extent provided in Sections 11 and 13 hereof, the officers and directors of each of the Company Parties and each person who controls any Company Party, Selling Stockholder or 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 any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

18. 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.

19. Each of the Company Parties and each of the Selling Stockholders acknowledges and agrees 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 several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each 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 Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice or solicitation of any action by the Underwriters with respect to any entity or natural person. The Company and each Selling Stockholder agrees that it will not claim that the Underwriters, 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. Moreover, each Selling Stockholder acknowledges and agrees that, although the Representative may be required or choose to provide certain Selling Stockholders with certain Regulation Best Interest and Form CRS disclosures in connection with the offering, the Representative and the other Underwriters are not making a recommendation to any Selling Stockholder to participate in the offering, enter into a “lock-up” letter, or sell any Shares at the price determined in the offering, and nothing set forth in such disclosures is intended to suggest that the Representative or any Underwriter is making such a recommendation.

29

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

21. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

22. Each Company Party, Selling Stockholder and 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.

23. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

(c) As used in this Section 23:

(i) “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

(ii) “Covered Entity” means any of the following:

(iii) “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.

(iv) “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd- Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

30

24. 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 respective counterparts shall together constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature 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., www.docusign.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.

Ladies and Gentlemen:

The undersigned understands that you, as Representative of the several Underwriters, propose to enter into an underwriting agreement (the “Underwriting Agreement”) with Core & Main, Inc., a Delaware corporation (the “Company”), Core & Main Holdings, LP, a Delaware limited partnership, and the Selling Stockholders listed on Schedule II to the Underwriting Agreement, providing for the public offering (the “Public Offering”), by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of Class A common stock, par value $0.01 per share (the “Class A Common Stock”) of the Company pursuant to a Registration Statement on Form S-3 filed with the U.S. Securities and Exchange Commission (the “SEC”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to offer and sell the Class A Common Stock, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representative on behalf of the Underwriters, the undersigned will not, and will not cause any direct or indirect affiliate to, in each case subject to the exceptions set forth in this letter agreement (this “Letter Agreement”), during the period beginning on the date of this Letter Agreement and ending at the close of business 60 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities

which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) owned by the undersigned as of the date hereof (collectively with the Common Stock, “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Lock-Up Securities, in cash or otherwise, (3) make any demand for or exercise any right with respect to the registration of any Lock-Up Securities, or (4) publicly disclose the intention to do any of the foregoing, provided that, for the avoidance of doubt, to the extent that the undersigned has demand and/or piggyback registration rights, the foregoing shall not prohibit the undersigned from notifying the Company privately that it is or will be exercising its demand and/or piggyback registration rights in respect of a registration to become effective following the expiration of the Restricted Period and undertaking preparations related thereto (which, for the avoidance of doubt, shall not include any filing with the SEC). The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions or arrangements (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) designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition or transfer (whether by the undersigned or any other person) of any economic consequences of ownership, in whole or in part, directly or indirectly, of any Lock-Up Securities, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Lock-Up Securities, in cash or otherwise.

Notwithstanding the foregoing, the undersigned may:

(a) transfer the undersigned’s Lock-Up Securities, without the prior written consent of the Representative,

(i) as a bona fide gift or gifts, or for bona fide estate planning purposes,

(ii) by will, other testamentary document or intestacy,

(iii) to any member of the undersigned’s immediate family or to any trust or other legal entity for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, or if the undersigned is a trust, to a trustor or beneficiary of the trust or to the estate of a beneficiary of such trust (for purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, current or former marriage, domestic partnership or adoption, not more remote than first cousin),

(iv)(1) to a partnership, limited liability company or other entity of which the undersigned and/or the immediate family of the undersigned are the legal and beneficial owners of all of the outstanding equity securities or similar interests; (2) to a corporation, member, partner, partnership, limited liability company, trust or other entity that is an affiliate (as defined in Rule 405 as promulgated by the SEC under the Securities Act of 1933, as amended) of the undersigned; or (3) to any investment fund or other entity controlling, controlled or managed by, or under common control with the undersigned or affiliates of the undersigned (including where the undersigned is a partnership, to a successor partnership or fund, or any other funds managed by such partnership),

(v) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iv) above,

(vi) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity, as part of a distribution to members, stockholders, partners or equityholders of the undersigned or its affiliates (including a fund managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by, or under common control with such manager or managing member or general partner or management company as the undersigned or who shares a common investment advisor with the undersigned),

(vii) by operation of law, pursuant to a qualified domestic order, divorce settlement, divorce decree or separation agreement or other final order of a court or regulatory agency,

(viii) to the Company from an employee (or “associate”) of the Company upon death, disability or termination of employment, in each case, of such employee (or “associate”),

(ix) as part of a sale of the undersigned’s Lock-Up Securities acquired in the Public Offering or in open market transactions on or after the date of the Prospectus,

(x) to the Company in connection with the vesting, settlement, or exercise of any profit units, appreciation rights, restricted stock units, options, warrants or other rights to purchase shares of Common Stock (including, in each case, by way of “net” or “cashless” exercise), including for the payment of exercise price and tax withholding and remittance payments due as a result of the vesting, settlement, or exercise of such profit units, appreciation rights, restricted stock units, options, warrants or rights, provided that any such shares of Common Stock received upon such exercise, vesting or settlement shall be subject to the terms of this Letter Agreement, and provided further that any such profit units, appreciation rights, restricted stock units, options, warrants or rights are held by the undersigned pursuant to an agreement or equity award granted under a stock incentive plan or other equity award plan that is described in the Registration Statement, the Pricing Disclosure Package and the Prospectus,
