(ii)Any attempt by the Stockholder Group to transfer any Shares or any rights hereunder in violation of this Section 2 shall be null and void ab initio.

(b)Permitted Transfers. Notwithstanding anything to the contrary contained in this Agreement, but subject to Section 2(c) hereof, each member of the Stockholder Group at any time may transfer all or a portion of such member’s Shares:

(i)to a Permitted Transferee, provided that such Permitted Transferee may transfer its Shares only to the Stockholder or a Permitted Transferee;

(ii)to a transferee in a Drag-Along Sale or a Tag-Along Sale pursuant to Section 3 or Section 4 hereof, respectively;

(iii)with the prior written consent of the Sponsor Group; and

(iv)to a member of the Sponsor Group or a member of the Company Group.

(c)Transfers in Compliance with Law; Substitution of Transferee. No transfer by any member of the Stockholder Group that would be permitted by Sections 2(a) and 2(b) hereof may be made pursuant to this Agreement unless (i) the transferee has agreed in writing to be bound by the terms and conditions of this Agreement pursuant to an instrument substantially in the form attached hereto as Annex I (other than if (x) the transfer is conducted pursuant to and in accordance with Section 3 or Section 4 hereof, (y) the transfer is to any member of the Sponsor Group or any member of the Company Group, or (z) the transfer is conducted following the Initial Public Offering pursuant to and in accordance with Rule 144 under the Securities Act), (ii) the transfer complies in all respects with the applicable provisions of this Agreement, (iii) the transfer complies in all respects with applicable federal, state and foreign securities laws, including, without limitation, the Securities Act and (iv) the transfer complies with all applicable Company Group policies and restrictions (including any trading “window periods” or other policies regulating xxxxxxx xxxxxxx).

3.Drag-Along Rights.

(a)If at any time the Sponsor Group receives an offer from a Third Party to effect or otherwise proposes to effect with a Third Party a transaction that, after giving effect to this Section 3, would constitute a Change in Control (a “Drag-Along Sale”), then each member

of the Stockholder Group hereby agrees that, upon the request of the Sponsor Group (and/or Topco, at the direction of the Sponsor Group) pursuant to a written notice (the “Drag-Along Sale Notice”) provided by the Sponsor Group at least twenty (20) Business Days prior to the proposed consummation of such Drag-Along Sale (the “Drag-Along Notice Date”), such member of the Stockholder Group shall sell a number of Shares owned by it to such Third Party in an amount (which amount shall be determined in good faith by the Sponsor Group) up to the product (rounded to the nearest whole number) of (i) the quotient determined by dividing (x) the total number of Company Securities that are proposed to be sold by the Sponsor Group to the Third Party purchaser in the contemplated Drag-Along Sale by (y) the total number of Company Securities owned by the Sponsor Group as of the close of business on the day immediately prior to the Drag-Along Notice Date, and (ii) the total number of Shares owned, or issuable upon exercise of any Stock Equivalents that are exercisable, by such member as of the close of business on the day immediately prior to the Drag-Along Notice Date, at the same price per share of Stock and upon the same economic terms and conditions as the Sponsor Group, including representations, warranties, covenants, and indemnities substantially similar to those to be made by the Sponsor Group and/or Topco (except that, (x) in the case of representations and warranties pertaining specifically to the Sponsor Group and/or Topco, each member of the Stockholder Group shall make comparable representations and warranties pertaining specifically to itself, (y) if the Drag-Along Sale involves any non-cash consideration, any rights or restrictions with respect to the non-cash consideration payable to each member of the Stockholder Group shall be proportionate to the relative size of ownership of such non-cash consideration, but shall not include any demand registration rights or board seats, consent rights, other governance rights or equity rollover rights and (z) if the Drag-Along Sale provides for cash consideration but a member of the Stockholder Group is given the opportunity by the proposed Third Party to receive securities in lieu of such cash consideration in connection with an equity rollover or similar transaction and such member elects to do so, such rollover securities shall be deemed to be the same form of consideration as cash); provided, that (I) all representations, warranties, covenants and indemnities shall be made by the Sponsor Group and/or Topco and the members of the Stockholder Group severally and not jointly, and (II) the maximum liability of a member of the Stockholder Group with respect to such representations and warranties, indemnities or other similar obligations shall not exceed the value (at such time) of the aggregate proceeds received by such member of the Stockholder Group in connection with the Drag-Along Sale; provided, further, that any such liability of such member of the Stockholder Group shall be satisfied first by the return of any cash proceeds received by such member of such Stockholder Group (including the cash proceeds from the sale of any securities or other non-cash consideration received by such member) and second by the return of any non-cash consideration (including securities) received by such member of the Stockholder Group.

(b)The provisions of this Section 3 shall apply regardless of the form of consideration received in the Drag-Along Sale; provided, that, in the event the consideration in a proposed Drag-Along Sale includes any securities (excluding any securities in connection with an equity rollover or similar transaction), and the receipt thereof by a member of the Stockholder Group required to sell Shares pursuant to Section 3(a) hereof would require (as determined by the Sponsor Group, upon the advice of its counsel (which may include in-house counsel)) under applicable law (i) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required by the receipt of such securities by the Sponsor Group and/or Topco, or (ii) the provision to such member of the Stockholder Group of any specified information regarding such securities or the issuer thereof that is not otherwise required to be provided for in connection with the Drag-Along Sale, then, in either case of (i) or (ii), in lieu of receiving such securities (as may be determined by the Sponsor Group, in its sole discretion), such member of

the Stockholder Group may, at the Sponsor Group’s direction, receive cash consideration equal to the fair value of such securities (as determined in good faith by the Sponsor Group).

(c)The members of the Stockholder Group shall cooperate in good faith with the Sponsor Group, in connection with the consummation of the transactions contemplated by Section 3(a) hereof and, in the event that the Drag-Along Sale is (i) a merger or other business combination of the Company or other members of the Company Group with a Third Party or (ii) a purchase of all or substantially all of the assets of the Company or other members of the Company Group, then, upon the request of the Sponsor Group, such members of the Stockholder Group shall be required to vote all Shares they hold (or execute one or more written consents) in favor of (and not otherwise oppose) such merger or business combination or such sale of all or substantially all of such assets and otherwise to take all actions reasonably necessary or appropriate to facilitate the consummation of the proposed transaction, and the members of each Stockholder Group hereby waive and agree to waive any and all dissenters or appraisal rights with respect thereto (provided that no member of the Stockholder Group shall be required to execute a restrictive covenants agreement except to the extent that the Sponsor Group agrees to be bound by such covenant or agrees to enter into such agreement; provided further, that no member of the Stockholder Group shall be required to execute any non-competition agreement or enter into such covenant). Each member of the Stockholder Group hereby grants to each member of the Sponsor Group an irrevocable proxy, coupled with an interest, to vote such member’s Shares (or execute one or more written consents) in accordance with this Section 3(c), which proxy shall be valid and remain in effect until the provisions of this Section 3 expire pursuant to Section 3(g) hereof. Without limiting the foregoing, upon written request by the Sponsor Group, in connection with a Drag-Along Sale, each member of the Stockholder Group will execute and deliver a custody agreement and power of attorney in form and substance reasonably satisfactory to the Sponsor Group with respect to the Shares which are to be sold by such member of the Stockholder Group pursuant hereto, containing customary provisions and providing, among other things, that such member of the Stockholder Group will deliver to and deposit in custody with the custodian and attorney-in-fact named therein a certificate or certificates (if such shares are certificated) representing such Shares (with undated stock powers duly endorsed in blank for transfer by the registered owner or owners thereof) and irrevocably appointing said custodian and attorney-in-fact as such member’s agent and attorney-in-fact with full power and authority to act on such member’s behalf with respect to the matters specified therein (such agreement, a “Custody Agreement and Power of Attorney”).

(e)The Sponsor Group shall, in its sole discretion, decide whether or not to pursue, consummate, postpone or abandon any Drag-Along Sale and the terms and conditions thereof. The Sponsor Group shall have no liability to any member of the Stockholder Group or the Company Group arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any such proposed Drag-Along Sale.

(f)Prior to the date of consummation of the Drag-Along Sale (such date, the “Drag-Along Sale Date”), each member of the Stockholder Group shall deliver a certificate or certificates (if certificated) for the Shares to be sold by such member of the Stockholder Group in connection with the Drag-Along Sale, with undated stock powers duly endorsed in blank for transfer by the registered owner or owners thereof, (x) to the Third Party acquiror in such Drag-Along Sale or (y) (to hold in escrow until the consummation of the Drag-Along Sale) the Company or the Sponsor Group, free and clear of all liens, encumbrances and restrictions, in the manner and at the address indicated in the Drag-Along Sale Notice.

The maximum number of Shares that each Tag-Along Stockholder will be entitled to include in such Tag-Along Sale (such Tag-Along Stockholder’s “Tag-Along Allotment”) shall be equal to the product (rounded to the nearest whole number) of (x) the number of Shares owned, or issuable upon exercise of any Stock Equivalents that are exercisable, by such Tag-Along Stockholder as of the close of business on the day immediately prior to the Tag-Along Notice Date and (y) a fraction, the numerator of which is the number of Company Securities proposed by the Sponsor Group to be transferred pursuant to the Tag-Along Sale and the denominator of which is the total number of Company Securities owned by the Sponsor Group as of the close of business on the day immediately prior to the Tag-Along Notice Date.

(b)The Sponsor Group shall provide each Tag-Along Stockholder with written notice (the “Tag-Along Sale Notice”) at least twenty (20) Business Days prior to the proposed closing date of the Tag-Along Sale (the “Tag-Along Sale Date”). Each Tag-Along Sale Notice shall set forth: (i) the name and address of the proposed Third Party transferee in the Tag-Along Sale; (ii) the number of Company Securities that are proposed to be transferred by the Sponsor Group pursuant to the Tag-Along Sale; (iii) the proposed amount and form of consideration to be paid for such securities and the terms and conditions of payment offered by the proposed Third Party transferee; (iv) the aggregate number of Company Securities held of record by the Sponsor Group as of the close of business on the day immediately prior to the date of the Tag-Along Sale Notice (the “Tag-Along Notice Date”); (v) the Tag-Along Stockholder’s Tag-Along Allotment, assuming the Tag-Along Stockholder elected to sell the maximum number of Shares permissible; and (vi) the anticipated Tag-Along Sale Date.

the Sponsor Group and/or Topco, such Tag-Along Stockholder shall make comparable representations and warranties pertaining specifically to itself, (y) if the Tag-Along Sale involves any non-cash consideration, any rights or restrictions with respect to the non-cash consideration payable to such Tag-Along Stockholder shall be proportionate to the relative size of ownership of such non-cash consideration, but shall not include any demand registration rights or board seats, consent rights, other governance rights or equity rollover rights and (z) if the Tag-Along Sale provides for cash consideration but such Tag-Along Stockholder is given the opportunity by the proposed Third Party transferee to receive securities in lieu of such cash consideration in connection with an equity rollover or similar transaction and such Tag-Along Stockholder elects to do so, such rollover securities shall be deemed to be the same form of consideration as cash); provided, that (A) all representations, warranties, covenants and indemnities shall be made by the Sponsor Group (and/or Topco) and such Tag-Along Stockholder severally and not jointly, and (B) the maximum liability of such Tag-Along Stockholder with respect to such representations and warranties, covenants, indemnities or other similar obligations shall not exceed the value (at such time) of the aggregate proceeds received by such Tag-Along Stockholder in connection with the Tag-Along Sale; provided, further that any such liability of such Tag-Along Stockholder shall be satisfied first by the return of any cash proceeds received by such member (including the cash proceeds from the sale of any securities or other non-cash consideration received by such member) and second by the return of any non-cash consideration (including securities) received by such Tag-Along Stockholder.

(c)Any Tag-Along Stockholder wishing to participate in the Tag-Along Sale shall provide written notice (the “Tag-Along Notice”) to the Sponsor Group and the Company no more than ten (10) days after the Tag-Along Notice Date irrevocably electing to participate in such Tag-Along Sale. The Tag-Along Notice shall set forth the number of Shares that such Tag-Along Stockholder elects to include in the Tag-Along Sale, which may be less than, but which shall not exceed, such Tag-Along Stockholder’s Tag-Along Allotment. The Tag-Along Notice given by any Tag-Along Stockholder shall constitute such Tag-Along Stockholder’s binding agreement to sell the Shares specified in the Tag-Along Notice on the terms and conditions applicable to the Tag-Along Sale; provided, that in the event that there is any material adverse change in the terms and conditions of such Tag-Along Sale applicable to the Tag-Along Stockholder (including, but not limited to, any decrease in the purchase price that occurs other than pursuant to an adjustment mechanism set forth in the agreement relating to the Tag-Along Sale or as a consequence of transaction expenses) after such Tag-Along Stockholder gives its Tag-Along Notice, then the Sponsor Group shall give notice such change to the Tag-Along Stockholder and the Tag-Along Stockholder shall have the right to withdraw from participation in the Tag-Along Sale with respect to all of its Shares affected thereby. If the proposed Third Party transferee is unwilling to purchase all of the Company Securities and Shares proposed to be Transferred by the Sponsor Group and all exercising Tag-Along Stockholders, then the Sponsor Group and each exercising Tag-Along Stockholder shall reduce, ratably among them (based on the number of Company Securities or Shares proposed to be included in such Transfer by the Sponsor Group or a Tag-Along Stockholder, as the case may be, as a percentage of the total number of Company Securities and Shares proposed to be included in such Transfer by the Sponsor Group and all Tag-Along Stockholders), the number of Company Securities and Shares to be transferred in the aggregate to the number of Company Securities and Shares that the proposed Third Party transferee is willing to purchase.

(d)If a Tag-Along Notice from any Tag-Along Stockholder is not received by the Sponsor Group prior to the lapse of the ten (10)-day period specified above, the Sponsor Group shall have the right to consummate the Tag-Along Sale without the participation of such Tag-Along Stockholder, who shall be deemed to have waived such Tag-Along Stockholder’s rights hereunder, but only on terms and conditions which are no more favorable in any material

respect to the Sponsor Group (and, in any event, at no greater a per share purchase price, except as the purchase price may be adjusted pursuant to any agreement relating to the relevant Tag-Along Sale) than as stated in the Tag-Along Sale Notice, and only if such Tag-Along Sale occurs on a date within one hundred and eighty (180) days after the proposed Tag-Along Sale Date. If such Tag-Along Sale does not occur within such one hundred and eighty (180)-day period, the shares or interests that were to be subject to such Tag-Along Sale thereafter shall continue to be subject to all of the restrictions contained in this Section 4.

(e)Prior to the Tag-Along Sale Date, each Tag-Along Stockholder shall deliver a certificate or certificates (if certificated) for the Shares to be sold by such Tag-Along Stockholder in connection with the Tag-Along Sale, with undated stock powers duly endorsed in blank for transfer by the registered owner or owners thereof, (x) to the Third Party transferee in such Tag-Along Sale or (y) (to hold in escrow until the consummation of the Tag-Along Sale) the Company or the Sponsor Group, free and clear of all liens, encumbrances and restrictions, in the manner and at the address indicated in the Tag-Along Sale Notice.

(b)In connection with any proposed Initial Public Offering, without the need for any action or consent of any Person, including any Stockholders, the Sponsor Group, may, in its sole discretion, develop and cause the implementation of an IPO Conversion (as defined below). In connection therewith, the Sponsor Group, in its sole discretion and acting alone, and without the need for any action or consent of any Person, including any member of the Stockholder Group, may take any and all actions to create and implement the Initial Public Offering of the IPO Corporation, including (i) amending this Agreement, including amendments that (1) alter the capital structure of the Company or (2) provide for the conversion of the Company in accordance with Delaware Law to any other entity, whether through the issuance, conversion or exchange of equity securities or otherwise, (ii) merging, converting or consolidating the Company, (iii) forming a Subsidiary holding company that would serve as the IPO Corporation and distributing its equity securities to the equityholders of the Company, (iv) transferring, domesticating or otherwise moving the Company to another jurisdiction within the United States, (v) exchanging Stock and Stock Equivalents for equity securities of the IPO Corporation, and (vi) taking such other steps as it deems necessary, advisable or convenient to create a suitable vehicle for an offering, and in each case for the express purpose of an initial offering of the equity securities of the IPO Corporation for sale to the public in the Initial Public Offering (any such action, an “IPO Conversion”).
