NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto, intending to be legally bound, hereby agree as follows:

1. Services. The Springboard Companies and the Managers acknowledge and agree that the Managers, by and through itself and/or its successors, assigns, affiliates, officers, employees and/or representatives and third parties as the Managers in their sole discretion may

In providing services to the Springboard Companies, the Managers and Manager Designees have acted, and will continue to act, as independent contractors and it is expressly understood and agreed that this Agreement is not intended to create, and does not create, any partnership, agency, joint venture or similar relationship and that no party has the right or ability to contract for or on behalf of any other party or to effect any transaction for the account of any other party.

2. Payment of Fees.

(a) At Completion, the Springboard Companies shall, jointly and severally, pay AH, CPPIB and Silver Lake (or their affiliate designees) an aggregate transaction fee of $60,000,000 (the “Transaction Fee”), which will be divided among AH, CPPIB and Silver Lake as separately agreed among them.

(b) Each payment made pursuant to this Section 2 shall be paid by wire transfer of immediately available federal funds to such respective account(s) as the respective Managers may specify to the Springboard Companies in writing prior to such payment.

(c) The fees payable pursuant to this Section 2 may be allocated by the Managers to their affiliates or other designees at the respective Managers’ discretion.

3. Deferral. Any fee or other amount that would have been paid to the Managers (or their designees) pursuant to Section 2 above or Section 5 below absent the restrictions, if any, in any financing or similar agreements (the “Financing Documents”) applicable to the Springboard Companies (the “Deferred Fees”) will remain payable and accrue until the next succeeding period in which such amounts could, consistent with the Financing Documents, be paid, and will be paid, without interest, in such succeeding period (in addition to such other amounts that would otherwise be payable at such time) in the manner set forth in Section 2.

4. Term. This Agreement will continue in full force and effect until December 31, 2021. Notwithstanding the foregoing sentence, this Agreement may be terminated at any time by the Managers upon notice to the Company, and this Agreement shall terminate (a) automatically upon an IPO unless otherwise determined by the Managers and (b) if decided by the board of directors of the Company in connection with any Change of Control. The termination of this Agreement will not relieve a party from liability for any breach of this Agreement on or prior to such termination. In the event of a termination of this Agreement, the Springboard Companies will pay the Managers (or their respective designees), as applicable, any unpaid portion of the Transaction Fee (pursuant to Section 2(a) above), Deferred Fees (pursuant to Section 3 above) and expenses and indemnification claims (pursuant to Section 5(a) below) due with respect to, or made during, the periods prior to the date of termination.

The Springboard Companies, jointly and severally, will indemnify, exonerate and hold each of the Managers, the Manager Designees and each of their respective partners, shareholders, members, affiliates, associated investment funds, directors, officers, fiduciaries, managers, controlling persons, employees and agents and each of the partners, shareholders, members, affiliates, associated investment funds, directors, officers, fiduciaries, managers, controlling persons, employees and agents of each of the foregoing (collectively, the “Indemnitees”), each of whom is an intended third party

3

beneficiary of this Agreement and may specifically enforce the Springboard Companies’ obligations hereunder, free and harmless from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and out-of-pocket expenses in connection therewith (including reasonable attorneys’ and accountants’ fees and expenses) (collectively, the “Liabilities”) incurred by the Indemnitees or any of them before the date of this Agreement (collectively, the “Indemnified Liabilities”), as a result of, arising out of, or in any way relating to (i) this Agreement, any transaction to which any of the Springboard Companies is a party or any other circumstances with respect to any of the Springboard Companies prior to Completion (including but not limited to service as a Manager-designated member of the board of directors or analogous governing body of any of the Springboard Companies, but excluding any such Indemnified Liabilities to the extent such Indemnified Liabilities arise out of any breach of this Agreement, the Shareholders Agreement or the Settlement Agreement by such Indemnitee or its affiliated or associated Indemnitees or other related persons), (ii) operations of, or services provided by the Managers or the Manager Designees to, the Springboard Companies, or any of their respective affiliates (other than to other portfolio companies of a Manager or such Manager’s affiliated investment vehicles) prior to Completion (including but not limited to any indemnification obligations assumed or incurred by any Indemnitee to or on behalf of any of the Springboard Companies or any of their accountants or other representatives, agents or affiliates), (iii) the Indemnitee’s purchase and/or ownership or prospective purchase and/or ownership of any equity securities of the Springboard Companies arising prior to Completion, or (iv) any litigation to which any Indemnitee is made a party in its capacity as a stockholder or owner, or prospective stockholder or owner, of interests in the Springboard Companies (or party related thereto) or a partner, shareholder, member, affiliate, associated investment fund, director, officer, fiduciary, manager, controlling person, employee or agent of any of the foregoing arising prior to Completion; provided that clauses (iii) and (iv) shall not apply in respect of matters arising under the Settlement Agreement; provided that the foregoing indemnification rights will not be available to the extent that any such Indemnified Liabilities arose on account of such Indemnitee’s willful misconduct; and provided, further, that if and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, the Springboard Companies hereby agree to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. For purposes of this Section 5(b), none of the circumstances described in the limitations contained in the two provisos in the immediately preceding sentence will be deemed to apply absent a final non-appealable judgment of a court of competent jurisdiction to such effect, in which case to the extent any such limitation is so determined to apply to any Indemnitee as to any previously advanced indemnity payments made by the Springboard Companies, then such payments will be promptly repaid by such Indemnitee to the Springboard Companies without interest. The rights of any Indemnitee to indemnification hereunder will be in addition to any other rights any such person may have under any other agreement or instrument referenced above or any other agreement or instrument to which such Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under law or regulation. None of the Indemnitees shall in any event be liable to the Springboard Companies for any act or omission suffered or taken by such Indemnitee that does not constitute gross negligence or willful misconduct; provided that this sentence shall not apply to obligations under the Settlement Agreement. If all Indemnitees are similarly situated with respect to their interests in a matter that may be an Indemnified Liability and that is not based on a Third-Party Claim, the Indemnitees may enforce their rights pursuant

4

to this Section 5(b) only with the consent of holders of 50% of the Shares (as defined in the Shareholders Agreement) held by the Indemnitees. A “Third-Party Claim” means any (i) claim brought by a person other than the Springboard Companies or any Indemnitee and (ii) any derivative claim brought in the name of the Springboard Companies that is initiated by a person other than an Indemnitee. The Springboard Companies hereby agree that they are the indemnitors of first resort (i.e., their obligations to any Indemnitee under this Agreement are primary and any obligation of any Manager (or any affiliate thereof other than the Springboard Companies) to provide advancement or indemnification for the same Indemnified Liabilities (including all interest, assessment and other charges paid or payable in connection with or in respect of such Indemnified Liabilities) incurred by Indemnitee are secondary), and if any Manager (or any affiliate thereof other than the Springboard Companies) pays or causes to be paid, for any reason, any amounts otherwise indemnifiable hereunder or under any other indemnification agreement (whether pursuant to contract, bylaws or charter) with any Indemnitee, then (i) such Manager (or such affiliate, as the case may be) shall be fully subrogated to all rights of Indemnitee with respect to such payment and (ii) the Springboard Companies shall reimburse such Manager (or such other affiliate) for the payments actually made. Each of the Springboard Companies hereby unconditionally and irrevocably waives, relinquishes and releases (and covenants and agrees not to exercise, and to cause each affiliate of any of the Springboard Companies not to exercise), any claims or rights that any of the Springboard Companies may now have or hereafter acquire against any Indemnitee (in any capacity) that arise from or relate to the existence, payment, performance or enforcement of one of the Springboard Companies’ obligations under this Agreement or under any indemnification obligation (whether pursuant to any other contract, any organizational document or otherwise), including any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of any Indemnitee against any Indemnitee, whether such claim, remedy or right arises in equity or under contract, statute, common law or otherwise, including any right to claim, take or receive from any Indemnitee, directly or indirectly, in cash or other property or by set-off or in any other manner, any payment or security or other credit support on account of such claim, remedy or right. None of the Indemnitees will be liable to the Springboard Companies or any of their affiliates for any act or omission suffered or taken by such Indemnitee that does not constitute willful misconduct. The foregoing indemnification set forth in this Section 5(b) shall not be available to any Liability that would otherwise be an Indemnified Liability hereunder if it is incurred as a result of, arises out of, or in any way relates to: (1) any dispute where any Manager or Manager Designee or any of their respective affiliated or associated Indemnitees are adverse to the Springboard Companies (other than relating to a breach of this Agreement) or any other Manager, Manager Designee or any of their respective affiliated or associated Indemnitees (provided that impleader claims (but not including cross claims that are not for contribution) or claims for contribution shall not be considered being adverse); (2) any dispute which involves any of AH, CPP or Silver Lake other than in their various capacities as a Manager or Manager Designee, shareholder, director, advisor or prospective shareholder, director or advisor of any of the Springboard Companies; or (3) any dispute between any Manager or Manager Designee on the one hand, and any of its affiliates, shareholders or directors, on the other hand.

(c) Notwithstanding anything to the contrary set forth in Sections 5(a) or 5(b) above or elsewhere in this Agreement, the Managers agree that (i) any amount that could otherwise be claimed from either the Sellers (as defined in the Purchase Agreement) or the

5

Springboard Companies pursuant to the Purchase Agreement (including, without limitation, clause 9 thereof) or from Joltid or its affiliates under the Settlement Agreement shall be claimed thereunder and only in the event of a shortfall any claim may be made under this Agreement; and (ii) (x) all claims not satisfied in full in accordance with the preceding clause (i) shall next be made against the Springboard Companies in accordance with the indemnification provisions set forth above in Section 5(b) of this Agreement and (y) only to the extent not satisfied by the Springboard Companies in accordance therewith, shall any contribution be sought under the contribution provision in the Consortium Agreement among the Managers, dated as of September 1, 2009, as amended on November 5, 2009, and as further amended from time to time.

6. Disclaimer and Limitation of Liability; Opportunities.

(a) Disclaimer; Standard of Care. No Manager or any Manager Designee makes any representations or warranties, express or implied, in respect of the services that have been or to be provided by the Managers or the Manager Designees hereunder. Without limiting any other obligations that it may have to the Springboard Companies or any of their respective affiliates, in no event will the Managers, the Manager Designees or Indemnitees be liable to the Springboard Companies or any of their respective affiliates for any act, alleged act, omission or alleged omission that does not constitute gross negligence or willful misconduct of the Managers, the Manager Designees or Indemnitees as determined by a final, non-appealable determination of a court of competent jurisdiction.

(b) Limitation of Liability. Except to the extent separately agreed with the Springboard Companies, in no event will a Manager, a Manager Designee or any of their respective Indemnitees be liable to the Springboard Companies or any of their affiliates for any punitive, indirect, special, incidental or consequential damages, including, without limitation, lost profits or savings, diminution in value, whether or not such damages are foreseeable, or for any third party claims (whether based in contract, tort or otherwise), relating to the services that have been or to be provided by a Manager or a Manager Designee hereunder.

None of the parties hereto will have the right to assign this Agreement without the prior written consent of each of the other parties; provided, however, that (a) each Manager may assign all or part of its rights and obligations hereunder to any of its respective affiliates, in which event such Manager will no longer be entitled to any fees under Section 2 and reimbursement of expenses under Section 5(a) and will be released of all of its obligations hereunder and (b) the provisions hereof for the benefit of Indemnitees of the Managers will inure to the benefit of such Indemnitees and their successors and assigns and each of such Indemnitees shall be third party beneficiaries entitled to enforce such provisions against the Springboard Companies.

8. Amendments and Waivers. No amendment or waiver of any term, provision or condition of this Agreement will be effective, unless in writing and executed by each of the Managers and the Company; provided that no amendment or waiver of any term, provision or condition of this Agreement that is adverse to the interests of the Other Managers under the Master Management Services Agreement or eBay under the eBay Management Services Agreement will be effective unless it is consented to in writing by, in the case of any amendment

No waiver on any one occasion will extend to or effect or be construed as a waiver of any right or remedy on any future occasion. No course of dealing of any person nor any delay or omission in exercising any right or remedy will constitute an amendment of this Agreement or a waiver of any right or remedy of any party hereto.
