Any attempt to transfer any Shares or any rights thereunder in violation of the preceding sentence shall be null and void ab initio.

No Stockholder shall avoid the provisions of this Agreement by making one or more transfers to one or more Permitted Transferees and then disposing of all or any portion of such party’s interest in any such Permitted Transferee, and any transfer or attempted transfer in violation of this covenant shall be null and void ab initio.

2.6 Exception. Notwithstanding anything to the contrary set forth in this Agreement (including this Article 2 and Article 3), any Stockholder may at any time transfer its Shares pursuant to a Sale Transaction approved by the Board of Directors.

3. Right of First Offer.

3.1 Proposed Voluntary Transfers.

(a) Offering Notice. If at any time after June 30, 2008 but prior to the IPO Effectiveness Date, any Stockholder (a “Selling Stockholder”) wishes to transfer in a bona fide transaction all or any portion of its or his Shares to any Person (other than pursuant to Sections 2.2 and 2.6) (a “Third Party Purchaser”), such Selling Stockholder shall offer such Shares first to the Company, by sending written notice (an “Offering Notice”) to the Company, which shall state (i) the number of Shares proposed to be transferred (the “Offered Securities”); (ii) the proposed purchase price per Share for the Offered Securities, which shall not be greater than the fair market value thereof, determined in the manner set forth in the penultimate sentence of this Section 3.1(a) (the “Offer Price”); and (iii) the terms and conditions of such sale. The Offering Notice shall also include a determination by a nationally recognized investment banking firm or other nationally recognized expert experienced in the valuation of companies engaged in the business conducted by the Company (and selected by the Selling Stockholders) of the fair market value of the Offered Securities, which fair market value shall be determined by such firm or expert without regard to any “minority” or “illiquidity” discount or “control” premium. Upon delivery of the Offering Notice, such offer shall be irrevocable unless and until the right of first offer provided for herein shall have been waived or shall have expired.

(b) Company Option; Exercise. For a period of thirty (30) days after the giving of the Offering Notice pursuant to Section 3.1(a) (the “Company Option Period”), the Company or its designee(s) shall have the right (the “Company Option”) but not the obligation to purchase all, but not less than all, of the Offered Securities at a purchase price equal to the Offer Price of the Offered Securities and upon the terms and conditions set forth in the Offering Notice. The right of the Company and/or its designee(s) to purchase all of the Offered Securities under this Section 3.1(b) shall be exercisable by delivering written notice of the exercise thereof, prior to the expiration of the Company Option Period, to the Selling Stockholder, which notice shall state the number of Offered Securities proposed to be purchased by the Company or its designee(s). The failure of the Company and/or its designee(s) to respond within the Company Option Period shall be deemed to be an irrevocable waiver of the Company Option; provided that, the Company may waive its rights under this Section 3.1(b) prior to the expiration of the Company Option Period by giving written notice to the Selling Stockholder.

(c) Closing. The closing of the purchase of the Offered Securities purchased by the Company or its designee(s) under Section 3.1(b) shall be held at the executive office of the Company at 11:00 a.m., local time, on the fiftieth (50th) day after the giving of the Offering Notice pursuant to Section 3.1(a) or at such other time and place as the parties to the transaction may agree. At such closing, the Selling Stockholder shall deliver certificates representing the Offered Securities, duly endorsed for transfer and accompanied by all requisite transfer taxes, if any, and such Offered Securities shall be free and clear of any Liens (other than those arising hereunder and those attributable to actions by the purchasers thereof) and the Selling Stockholder shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and record owner of such Offered Securities, that the transfer has been duly authorized by the Selling Stockholder and that the transfer does not conflict with the Selling Stockholder’s organizational documents, if applicable, material contracts or any laws, rules or regulations applicable to such Selling Stockholder or any of its properties or assets. The Selling Stockholder shall not be required to make any additional representations and warranties. The Company and/or its designee(s), as the case may be, purchasing Offered Securities shall deliver at the closing payment in full in immediately available funds for the Offered Securities purchased by it or him. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate.

(d) Sale to a Third Party Purchaser. Unless the Company or its designee(s) elects to purchase all, but not less than all, of the Offered Securities pursuant to Section 3.1(b), the Selling Stockholder may sell all, but not less than all, of the Offered Securities to a Third Party Purchaser in a bona fide transaction at a price per Share that is not less than the Offer Price; provided, however, that such sale is made pursuant to an agreement entered into within 90 days after (x) the expiration of the

Company Option Period or (y) the waiver by the Company of its option to purchase the Offered Securities (the “Contract Date”). If such sale is not consummated within ninety (90) days after the Contract Date for any reason, then the restrictions provided for herein shall again become effective, and no transfer of such Offered Securities may be made thereafter by the Selling Stockholder without again offering the same to the Company in accordance with this Section 3.1. Notwithstanding any other provision of this Agreement, no transfer may be made pursuant to this Section 3.1 except in accordance with Section 2.4.

4.2 Preemptive Rights; Exercise.

(a) Subject to the Standstill Ceiling set forth in Section 6, for a period of twenty (20) days after the giving of the New Issuance Notice pursuant to Section 4.1(a) and for a period of ten (10) days after the giving of any Additional Preemptive Rights Notice pursuant to Section 4.1(b), each of the Preemptive Rightholders shall have the right to purchase the number of the New Securities set forth in the New Issuance Notice and the Additional Preemptive Rights Notice, as the case may be, at a purchase price equal to the Proposed Price and upon the same terms and conditions set forth in the New Issuance Notice and the Additional Preemptive Rights Notice, as the case may be. Any of the General Atlantic Stockholders may assign to any of its Affiliates all or any portion of its rights as a Preemptive Rightholder pursuant to this Section 4.2.

The failure of a Preemptive Rightholder to respond within such 20-day period or 10-day period, as the case may be, shall be deemed to be a waiver of such Preemptive Rightholder’s rights under Section 4.2(a); provided that, each Preemptive Rightholder may waive its rights under Section 4.2(a) prior to the expiration of such 20-day period or 10-day period, as the case may be, by giving written notice to the Company.

4.3 Closing. The closing of the purchase of New Securities subscribed for by the Preemptive Rightholders under Section 4.2 shall be held at the executive office of the Company at 11:00 a.m., local time, on (a) the date of the closing of the sale to the Subject Purchaser made pursuant to Section 4.4 or (b) at such other time and place as the parties to the transaction may agree. At such closing, the Company shall

deliver certificates representing the New Securities, and such New Securities shall be issued free and clear of all Liens (other than those arising hereunder, arising under the Registration Rights Agreement, the Certificate of Incorporation, the Bylaws, securities laws and those attributable to actions by the purchasers thereof) and the Company shall so represent and warrant, and further represent and warrant that such New Securities shall be, upon issuance thereof to the Preemptive Rightholders and after payment therefor, duly authorized, validly issued, fully paid and nonassessable. In addition, the Company shall make the same additional representations and warranties to the Preemptive Rightholders such as the Company shall have agreed to make to the Subject Purchaser. Each Preemptive Rightholder purchasing the New Securities shall deliver at the closing payment in full in immediately available funds for the New Securities purchased by him or it. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate.

4.4 Sale to Subject Purchaser. The Company may sell to the Subject Purchaser all of the New Securities not purchased by the Preemptive Rightholders pursuant to Sections 4.2 and 4.3 on terms and conditions that are no more favorable to the Subject Purchaser than those set forth in the New Issuance Notice; provided, however, that, such sale is bona fide and made pursuant to a contract entered into within ninety (90) days following the earlier to occur of (i) the waiver by the Preemptive Rightholders of their option to purchase New Securities pursuant to Section 4.2, and (ii) the expiration of the 20-day period or the 10-day period, as the case may be, referred to in Section 4.2. If such sale is not consummated within 90 days after such contract has been entered into for any reason, then the restrictions provided for herein shall again become effective, and no issuance and sale of New Securities may be made thereafter by the Company without again offering the same in accordance with this Section 4. The closing of any issuance and purchase pursuant to this Section 4.4 shall be held at a time and place as the parties to the transaction may agree within such 90-day period.

4.5 Initial Public Offering.

(a) Subject to applicable Requirements of Law and the Standstill Ceiling, in connection with the Company’s Initial Public Offering (provided that, the initial filing of the registration statement to register the Company’s securities (the “IPO Filing”) with the Commission occurs at least twelve (12) months after the date of this Agreement), the Company shall offer to each of the stockholders of the Company (including the General Atlantic Stockholders) and, in the Company’s sole discretion, other Persons (the “IPO Participants”) the right to purchase its IPO Participation Allotment (as hereinafter defined) at the final price per share (after deduction of such underwriters, broker or dealers fees, discounts and commissions) set forth on the front cover of the final prospectus included in the Registration Statement filed under the Securities Act for the Initial Public Offering by sending written notice (the “IPO Notice”) to the IPO Participants at such time as is reasonably determined by the Company and the managing underwriter of the Initial Public Offering. The IPO Notice shall state (i) that each IPO Participant has the right to purchase up to its IPO Participation Allotment, (ii)

the date by which each IPO Participant must make its election to purchase all or a portion of its IPO Participation Allotment and (iii) such other terms and conditions applicable to the purchase of the IPO Shares as may be reasonably required by the managing underwriter of the Initial Public Offering. For purposes hereof, “IPO Participation Allotment” means, (i) with respect to each stockholder of the Company, the excess of (1) the product of (x) 5% of the total number of shares of Common Stock offered in the Initial Public Offering (such 5% of the number of shares being offered referred to as the “IPO Shares”) multiplied by (y) a fraction, the numerator of which is the total number of shares of Common Stock owned by such stockholder and the denominator of which is the total number of shares of Common Stock owned by all stockholders of the Company (on a fully diluted basis) minus (2) such stockholder’s pro rata share (calculated based on the same fraction set forth in the immediately preceding clause (y)) of the total number of IPO Shares that the Company elects to offer to Persons other than the stockholders of the Company, and (ii) with respect to each Person other than the stockholders of the Company, the number of IPO Shares that the Company elects to offer to such Person. Any of the General Atlantic Stockholders may assign to any of its Affiliates all or any portion of its rights pursuant to this Section 4.5(a).

(b) Each IPO Participant’s purchase of IPO Shares shall occur simultaneously with the closing of the purchase and sale of the other shares distributed in such Initial Public Offering. It is the intent of the parties, subject to Section 4.5(c) below, that the IPO Shares issued to each of the IPO Participants shall be fully registered shares, offered and sold in such Initial Public Offering.

(c) In the event that the IPO Filing occurs prior to twelve (12) months of the date of this Agreement or the Company shall otherwise reasonably determine that making such IPO Participation Allotment available to the IPO Participants is inconsistent with applicable laws and regulatory restrictions, then each IPO Participant’s right to purchase its IPO Participation Allotment shall terminate and the Company shall in lieu thereof make a concurrent private placement to the IPO Participants of their IPO Participation Allotment which private placement shall be otherwise on the same terms as the initial public offering.

5. After-Acquired Securities. All of the provisions of this Agreement shall apply to all of the Shares and Common Stock Equivalents of the Company now owned or that may be issued or transferred hereafter to a Stockholder in consequence of any additional issuance, purchase, exchange or reclassification of any of such Shares or Common Stock Equivalents, corporate reorganization, or any other form of recapitalization, consolidation, merger, share split or share dividend, or that are acquired by a Stockholder in any other manner.

(b) shall at any time prior to the Standstill Expiration Date, propose (or publicly announce or otherwise disclose an intention to propose), any tender or exchange offer, merger, consolidation, share exchange, business combination, restructuring, recapitalization or similar transaction involving the Company that would constitute a Sale Transaction;

(c) shall at any time prior to the Standstill Expiration Date, propose or otherwise seek or solicit stockholders of the Company to nominate or attempt to nominate any Person for election as a Director (except in accordance with Section 7 and except as set forth in Article Fourth, Section (b) of the Certificate of Incorporation) or seek the removal or resignation of any Director (except in accordance with Section 7 and except as set forth in Article Fourth, Section (b) of the Certificate of Incorporation);

(d) shall at any time prior to the Standstill Expiration Date, otherwise seek to control the Board of Directors or the management of the Company or the Exchange (each of subsections (a) through (d), a “Restricted Action” and together, the “Restricted Actions”); or

(e) shall at any time prior to the Standstill Expiration Date (other than with respect to subsection (a) which applies before and after the Standstill Expiration Date), form, join or in any way participate in a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) or otherwise act in concert with any Person in connection with any of the Restricted Actions;

provided, however, that, notwithstanding the foregoing, any General Atlantic Stockholder may propose to take or take any of the actions set forth in subclauses (b), (c), (d) or (e) above at any time with the prior written consent of the Board of Directors; provided, further, that, notwithstanding the foregoing (v) the General Atlantic Director may, in his or her sole discretion, take any action or omit to take any action in his or her capacity as a Director, (w) each of the General Atlantic Stockholders may vote its shares of Capital Stock of the Company at any Stockholders Meeting or in a Written Consent in any manner it, in its sole discretion, determines, (x) each of the General Atlantic Stockholders may consent to or approve, or withhold consent to or approval of, any of the Major Actions, (y) any representative of General Atlantic or any of any of its Affiliates who

serves as a director of any other portfolio company of General Atlantic or its Affiliates may take any action or omit to take any action, in his or her sole discretion, in his or her capacity as a director of such portfolio company and (z) the General Atlantic Stockholders may collectively act as a “group” for the purpose of acquiring, holding, voting or disposing of any shares of Capital Stock of the Company or Common Stock Equivalents of the Company, but in such event may not undertake any Restricted Action.
