Ladies and Gentlemen:

This letter agreement sets forth the commitment of AlpInvest Partners Co-Investments 2009 C.V. and AlpInvest Partners Co-Investments 2010 II C.V. (each, an “Investor” and collectively, the “Investors”), subject to the terms and conditions contained herein, to purchase, or cause the purchase of, shares of common stock of Global Generations International Inc., a Delaware corporation (“Parent”). It is contemplated that, (i) pursuant to that certain Agreement and Plan of Merger (as amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among Parent, Global Generations Merger Sub Inc. a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and Xxxxxxxx.xxx Inc., a Delaware corporation (the “Company”), Merger Sub will merge with and into the Company with the Company surviving the merger as a wholly owned subsidiary of Parent (the “Merger”) and (ii) in connection with the transactions contemplated by the Merger and concurrently herewith, Parent, the Investors and each of the other parties providing the Other Equity Commitments (as defined below), are entering into an Interim Investors Agreement (the “Interim Investors Agreement”), which sets forth the agreements of such parties with respect to, among other things, certain matters set forth herein. Capitalized terms used but not defined herein have the meanings ascribed to them in the Merger Agreement.

1. Commitment. Each Investor hereby commits, subject to the terms and conditions set forth herein, that at or prior to the Closing, such Investor shall purchase, or cause the purchase of, the percentage amount of the total shares of common stock of Parent set forth opposite such Investor’s name in column 2 (Percentage) of Schedule A attached hereto for the amount of cash set forth opposite its name in column 3 (Total Commitment) of Schedule A attached hereto (the aggregate amount paid by each Investor, the “Commitment”, and the aggregate amount paid by all the Investors, the “Commitments”), which amount shall be used by Parent, together with the cash funds provided pursuant to the other equity commitment letters (the “Cash Commitments”, and the shares of Common Stock, Company Options and Company RSU Awards to be contributed to Parent by the Rollover Investors pursuant to the Rollover Contribution Agreements, the “Company Equity Commitments”) contemplated by the Merger Agreement and executed concurrently herewith (such other Cash Commitments and Company Equity Commitments, the “Other Equity Commitments”), solely for the purpose of allowing Parent to fund, to the extent necessary, a portion of the amounts payable by Parent at the Closing pursuant to, and in accordance with, the Merger Agreement, on the terms and subject to the conditions of the Merger Agreement, and related costs and expenses of Parent; provided, that no Investor shall, under any circumstances, be obligated to contribute to Parent at any time more than the amount of the Commitment set forth opposite its name in column 3 (Total Commitment)

of Schedule A attached hereto; provided, further, that the aggregate amount of liability of the Investors under this letter agreement shall at no time exceed the aggregate amount set forth opposite the names of the Investors in column 3 (Total Commitment) in Schedule A attached hereto. Each Investor may effect the purchase of shares of common stock of Parent directly or indirectly through one or more affiliated entities; provided, that no such action shall reduce the amount of such Investor’s Commitment or otherwise affect the obligations of such Investor under this letter agreement. The amount of the Commitments to be funded under this letter agreement may be reduced solely to the extent that Parent does not require all of the Commitments and the Other Equity Commitments to pay the amounts payable by Parent at the Closing pursuant to, and in accordance with, the Merger Agreement (and any related costs and expenses of Parent) by reason of Parent having obtained funds from other sources; provided, that if Parent does not require all of the Commitments and the Other Equity Commitments in order to pay the amounts payable by Parent at the Closing pursuant to, and in accordance with, the Merger Agreement (and any related costs and expenses), any such reduction in equity financing shall be applied pro rata among the Commitments and the Other Equity Commitments based on the amount of each respective commitment prior to giving effect to any such reduction; and provided, further, that the amount of the Commitment to be funded by each Investor shall not be reduced by more than 5% without such Investor’s consent. For the avoidance of doubt, the Commitment is payable only at the Closing upon written notice from Parent to the Investors of the satisfaction of the conditions set forth in Section 2(a) hereof (such conditions, the “Conditions,” and such notice the “Parent Notice”) and only for the uses described above, and the Commitment shall not be payable at any other time, under any other circumstance or for any other purpose. Parent may direct the Investors to pay the Commitment to a parent entity of Parent; provided that such parent entity has agreed in writing that it will pay the Commitment to Parent immediately upon the receipt of such payment (which agreement shall be reasonably satisfactory to the Company and shall not be amended without the approval of the Company). Parent hereby agrees to deliver the Parent Notice promptly (and in any event within one (1) calendar day) following the satisfaction of the Conditions.

2. Conditions. The obligation of the Investors to fund or cause the funding of the Commitment shall be subject to (a) the satisfaction in full, or waiver by Parent, of each of the conditions to Parent’s obligations to consummate the transactions as set forth in Sections 6.1 and 6.3 of the Merger Agreement (other than those conditions (i) that by their nature are to be satisfied at Closing or (ii) the failure of which to be satisfied is attributable to a breach by Parent or Merger Sub of their representations, warranties, covenants or agreements contained in the Merger Agreement), (b) Parent having received (simultaneously with, or prior to, the Closing), the proceeds of the Debt Financing, (c) (i) the concurrent funding of the other Cash Commitments and (ii) the contribution to Parent of the Company Equity Commitments, (d) (i) the substantially concurrent consummation of the Merger in accordance with the terms of the Merger Agreement or (ii) the Company having irrevocably confirmed in writing that if an order of specific performance is granted that would require Parent to consummate the Merger and the Debt Financing, the financing contemplated by this letter agreement and the financing contemplated by the Other Equity Commitments are funded, the Closing will occur and (e) the provision to the Investors or not less than seven (7) Amsterdam business days prior written notice of the Closing Date under the Merger Agreement. Parent hereby agrees to deliver to the Investors the prior written notice required under clause (e) upon the commencement of the Marketing Period under the Merger Agreement.

Subject to the terms and conditions of this letter agreement, the Company or the Sponsor, as applicable, shall have the right to enforce the Commitments directly against the Investors in such party’s own name irrespective of whether Parent pursues such injunction, specific performance or other equitable remedies. In no event shall this letter agreement or the Commitments herein be enforced by any Person unless each of the unfunded Other Equity Commitments is being concurrently enforced by such Person.

4. No Modification; Entire Agreement. This letter agreement may not be amended or otherwise modified without the prior written consent of the Company, Parent and each Investor.

Any transfer in violation of the preceding sentence shall be null and void.

5. Assignment. This letter agreement and each Investor’s Commitment hereunder shall not be assignable to any other Person without the prior written consent of the other parties hereto and the Company, and any attempted assignment without such consent shall be null and void and of no force and effect, except that each Investor may assign all or a portion of its obligations to fund the Commitment to one or more of its Affiliates (other than Parent or any subsidiary thereof); provided, however, that no such assignment shall relieve such Investor from any of its obligations hereunder. Each Investor acknowledges that the Company has entered into the Merger Agreement in reliance upon, among other things, the Commitments set forth herein.
