Certain terms used herein are defined in Section 20 hereof.

1. Representations and Warranties.

(i) The Company represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1.

(a) The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatic shelf registration statement (file number 333-190700) on Form S-3, including a related Base Prospectus, for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Securities, each of which has previously been furnished to you. The Company will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the rules thereunder, and, except to the extent the Representative shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

(b) On each Effective Date, the Registration Statement did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date (as defined herein) and on any date on which Option Securities are purchased, if such date is not the Closing Date (a “settlement date”), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or

warranties as to the information contained in or omitted from the Registration Statement, or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof.

(c) (i) The Disclosure Package and the price to the public, the number of Underwritten Securities and the number of Option Securities to be included on the cover page of the Final Prospectus, when taken as a whole and (ii) each electronic road show when taken together as a whole with the Disclosure Package and the price to the public, the number of Underwritten Securities and the number of Option Securities to be included on the cover page of the Final Prospectus, does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof.

(d) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(e) (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

The Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representative with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representative of such timely filing.

The Company will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Company will (i) notify promptly the Representative so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

This indemnity agreement will be in addition to any liability which the Company may otherwise have.

The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable and documented fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate

counsel at the expense of the indemnifying party. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all persons to be indemnified, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by Citigroup Global Markets Inc. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(e) In the event that the indemnity provided in paragraph (a), (b), or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Selling Shareholders and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company, one or more of the Selling Shareholders and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, by the Selling Shareholders and by the Underwriters from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Selling Shareholders and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, the Selling Shareholders and the Underwriters in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company and the Selling Shareholders shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, the Selling Shareholders or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (e), 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. For purposes of this Section 8, (i) each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an

Underwriter shall have the same rights to contribution as such Underwriter and (ii) each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (e).

(f) The liability of each Selling Shareholder under any claim relating to such Selling Shareholder’s representations and warranties contained in Section 1 hereof and under the indemnity and contribution agreements contained in this Section 8 shall be limited to an amount equal to the aggregate Purchase Price of the Securities sold by such Selling Shareholder to the Underwriters under this Agreement (less underwriting discounts and commissions). The Company and the Selling Shareholders may agree, as among themselves and without limiting the rights of the Underwriters under this Agreement, as to the respective amounts of such liability for which they each shall be responsible.

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter, the Selling Shareholders or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, the Selling Shareholders and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Company’s Class A Common Stock shall have been suspended by the Commission or the NASDAQ Global Market or trading in securities generally on the New York Stock Exchange and the NASDAQ Global Market shall have been suspended or limited or minimum prices shall have been established on either of such exchanges, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers, of each Selling Shareholder and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any Selling Shareholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representative, will be mailed, delivered or telefaxed to the Citigroup Global Markets Inc. General Counsel (fax no.: (▇▇▇) ▇▇▇-▇▇▇▇) and confirmed to the General Counsel, Citigroup Global Markets Inc., at ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇▇▇, Attention: General Counsel; if sent to the Company, will be mailed, delivered or telefaxed to Zillow, Inc., Chief Executive Officer, (fax no.: (▇▇▇) ▇▇▇-▇▇▇▇) and confirmed to the General Counsel at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, attention of the General Counsel; or if sent to any Selling Shareholder, will be mailed, delivered or telefaxed and confirmed to it at the address set forth above for the Company.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. No Fiduciary Duty. The Company and the Selling Shareholders hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Selling Shareholders, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company or the Selling Shareholders and (c) the engagement of the Underwriters by the Company and Selling Shareholders in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company and the Selling Shareholders agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company or the Selling Shareholders on related or other matters). The Company and the Selling Shareholders agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to them, in connection with such transaction or the process leading thereto.

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

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Waiver of Jury Trial. The Company and the Selling Shareholders hereby irrevocably waive, 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.

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Re:

Zillow, Inc. – Lock-Up Agreement

Ladies and Gentlemen:

This letter agreement (this “Agreement”) is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”), between Zillow, Inc., a Washington corporation (the “Company”), and a group of Underwriters named therein (collectively, the “Underwriters”), relating to an underwritten public offering of Common Stock, $0.0001 par value (the “Shares”), of the Company (the “Public Offering”).

In order to induce you and the other Underwriters to enter into the Underwriting Agreement, the undersigned will not, without the prior written consent of Citigroup Global Markets Inc., offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly (or enter into any transaction which is designed to, or might reasonably be expected to, result in such disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the undersigned), including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission (the “SEC”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder with respect to, any shares of capital stock of the Company or any securities convertible into, or exercisable or exchangeable for capital stock of the Company (collectively, the “Restricted Securities”), or publicly announce an intention to effect any such transaction, for a period of 45 days (the “Lock-Up Period”) after the date of the Underwriting Agreement (the “Public Offering Date”), other than:

(a) Restricted Securities disposed of by bona fide gift, will or intestacy or through transfer to an immediate family member or a trust formed for the benefit of an immediate family member;

(b) Restricted Securities acquired in open market transactions after the Public Offering Date;

(c) if the undersigned is a business entity, distributions of Restricted Securities to (1) members, partners, stockholders or other equity owners of the undersigned or (2) wholly-owned subsidiaries or affiliated funds of the undersigned, which means with respect to a limited liability company or a limited partnership, a fund or entity managed by the same manager or managing member or general partner or management company;

(d) if the undersigned is a trust, transfers of Restricted Securities to a trustor or beneficiary of the trust;

(e) in connection with the conversion of any shares of the Company’s Class B common stock pursuant to the terms of the Company’s articles of incorporation into other shares of capital stock of the Company; provided that any such shares of capital stock received upon any such conversion shall be subject to the terms of this Agreement;

(f) dispositions of Restricted Securities pursuant to a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act, relating to the sale of Restricted Securities, provided that such plan was established prior to the execution of this Agreement by the undersigned;

(g) in connection with the exercise of options to purchase Restricted Securities pursuant to employee benefit plans on the terms of such plans as described in the preliminary prospectus used in the road show and final prospectus relating to the Public Offering or as filed, or incorporated by reference, as exhibits to the registration statement on Form S-3 of which such prospectuses are a part; provided that no more than 25% of the shares of Common Stock of the Company subject to options held by the undersigned as of the date of this Agreement may be exercised through cashless exercise unless such option or options would expire during the Lock-Up Period, in which case all of such option or options that would so expire may be exercised on a cashless basis (there shall be no limit with respect to cash exercises); and provided, further, that any such shares of Common Stock of the Company received upon any such exercise shall be subject to the terms of this Agreement; and

(h) dispositions of Restricted Securities pursuant to the Underwriting Agreement in connection with the Public Offering;

provided that in the case of any transfer or distribution pursuant to clause (a), (c) or (d), above, each donee, transferee or distributee shall execute and deliver to Citigroup Global Markets Inc., a lock-up letter agreement in the form of this Agreement and there shall be no disposition for value and no filing by any party under the Exchange Act reporting a reduction in beneficial ownership of the Shares (other than a filing on a Form 5 made after the expiration of the Lock-Up Period); provided, further, that in the case of any transaction pursuant to clause (b), above, no filing by any party under the Exchange Act or other public announcement shall be required or shall be made voluntarily in connection with subsequent sales of Restricted Securities acquired in such open market transactions; and provided, further, that in the case of any transaction pursuant to clause (e), Citigroup Global Markets Inc. shall receive notice from the undersigned of any filing by any party under the Exchange Act or other public announcement related to any such conversions at least one (1) business day prior to such filing or announcement. For purposes of this Agreement, “immediate family” means any relationship by blood, marriage, domestic partnership or adoption, no more remote than a first cousin. Any request by the undersigned for a release or waiver by Citigroup Global Markets Inc. of the restrictions set forth herein must be made in writing and delivered by the undersigned to both Citigroup Global Markets Inc. and the Company.

In the event that Citigroup Global Markets Inc. releases, in full or in part (a “Release”), any officer, director or Selling Shareholder (a “Triggering Shareholder”) from the restrictions of any lock-up agreement similar to this Agreement signed by such Triggering Shareholder for the benefit of the Underwriters in connection with the Underwriting Agreement (a “Triggering Release”), then the undersigned shall be automatically released (subject, in the case of directors and officers of the Company, to any required notice and announcement procedures provided for herein) to the same extent with respect to the same percentage of Restricted Securities of the undersigned as the percentage of Restricted Securities being released in the Triggering Release represent with respect to the Restricted Securities held by the Triggering Shareholder at the time of the request of the Triggering Release. In the event of a Triggering Release, the Company shall use reasonable best efforts to notify the undersigned within five (5) business days of the occurrence of such Triggering Release, which notification obligation may be satisfied by the issuance of a press release through a major news service announcing such Triggering Release; provided that the failure to by the Company to give such notice shall not give rise to any claim or liability against the Company or the Underwriters except, in respect of the Company, in the case of bad faith on the part of the Company.

Notwithstanding the foregoing, if a Release is in response to a request from the Company’s management team to release a shareholder of the Company from the foregoing restrictions for a number of Restricted Securities whose aggregate value (measured as the closing price on the day before the release occurs) is not more than $500,000 and such release is requested in response to a financial hardship for which such shareholder has no other reasonably available sources of liquidity, then such Release shall not be deemed to be a Triggering Release.

If the undersigned is an officer or director of the Company, (i) Citigroup Global Markets Inc. agrees that, at least three (3) business days before the effective date of any release or waiver of the foregoing restrictions with respect to Restricted Securities of the undersigned Citigroup Global Markets Inc. will notify the Company of the impending release or waiver, and (ii) the proposed Underwriting Agreement will provide that Company agrees to announce the impending release or waiver by press release through a major news service at least two (2) business days before the effective date of the release or waiver. Any release or waiver granted by Citigroup Global Markets Inc. hereunder to any such officer or director shall only be effective two (2) business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

If (i) the Company issues an earnings release or material news, or a material event relating to the Company occurs, during the last 17- day period of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the Lock-Up Period will be extended, and the restrictions imposed by this Agreement shall

continue to apply, until the expiration of the 18-day period beginning on (and including) the issuance of the earnings release or material news or the occurrence of the material event, unless Citigroup Global Markets Inc. waives, in writing, such extension or deferral. The undersigned hereby acknowledges that the Company has agreed in the Underwriting Agreement to provide written notice of any event that would result in an extension of the Lock-Up Period and agrees that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned.

This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

This Agreement shall automatically terminate and be of no further effect upon the earliest to occur, if any, of: (i) either Citigroup Global Markets Inc. or the Company advising the other in writing, prior to execution of the Underwriting Agreement, that it has determined not to proceed with the Public Offering, or (ii) the termination of the Underwriting Agreement prior to payment for and delivery of the Shares to be sold pursuant thereto.

Unless this Agreement is terminated pursuant to the immediately preceding sentence, this Agreement shall supersede and replace any prior market stand-off or lock-up agreements of the undersigned for the benefit of any underwriters in connection with the Public Offering, including, without limitation, any such agreements for which any such underwriters are intended third party beneficiaries.
