ANNEX A - INDEMNIFICATION AGREEMENT

As part of the consideration for the agreement of AEA to furnish its services under this Agreement, the Company and GYP III hereby agree to indemnify and hold harmless AEA and its affiliates and the respective managing directors, officers, directors, investors, shareholders, members, partners, employees and agents of, and persons controlling, AEA or any of its affiliates within the meaning of either Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as amended, and each of their respective successors and assigns (collectively, the “Indemnified Persons”) from and against all claims, liabilities, expenses, losses or damages (or actions in respect thereof) related to or arising out of actions taken (or omitted to be taken) by AEA or its affiliates pursuant to the terms of this Agreement and/or in connection with the acquisition or operation of the Business (as defined in the Purchase Agreement), or AEA’s or any of its affiliates’ role in connection therewith; provided, however, that the Company and GYP III shall not be responsible for any claims, liabilities, expenses, losses and damages to the extent that it is finally judicially determined that they result primarily from actions taken or omitted to be taken by AEA or its affiliates in bad faith or due to AEA’s or such affiliate’s gross negligence or willful misconduct.  If for any reason (other than the bad faith, gross negligence or willful misconduct of AEA or its affiliates as provided above) the foregoing indemnity is unavailable to the Indemnified Persons or insufficient to hold the Indemnified Persons harmless, then the Company and GYP III shall contribute to the amount paid or payable by the Indemnified Persons as a result of such claim, liability, expense, loss or damage in such proportion as is appropriate to reflect not only the relative benefits received by the Company and GYP III on the one hand and AEA on the other hand, but also the relative fault of the Company, GYP III and AEA, as well as any relevant equitable considerations, subject to the limitation that in any event AEA’s aggregate contribution to all claims, liabilities, expenses, losses and damages (except to the extent judicially determined to have been primarily caused by the bad faith, gross negligence or willful misconduct of AEA or its affiliates) shall not exceed the amount of fees actually received by AEA pursuant to this Agreement.

Promptly after receipt by AEA of notice of any complaint or the commencement of any action or proceeding with respect to which indemnification may be sought against the Company and/or GYP III, AEA will notify the Company and GYP III in writing of the receipt or commencement thereof, but failure to notify the Company and GYP III will relieve the Company and GYP III and from any liability which they may have hereunder only if, and to the extent that, such failure results in the forfeiture of substantial rights and defenses, and will not in any event relieve the Company and GYP III from any other obligation to any Indemnified Person other than under this Indemnification Agreement.  The Company and/or GYP III shall assume the defense of such action (including payment of fees and disbursements of counsel) insofar as such action shall relate to any alleged liability in respect of which indemnity may be sought

A-1

against the Company and/or GYP III.  AEA shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and disbursements of such counsel shall be at the expense of AEA unless employment of such counsel has been specifically authorized by the Company and GYP III in writing.  The Company and GYP III shall pay the fees and expenses of one separate counsel for AEA and any other Indemnified Persons if the named parties to any such action (including any impleaded parties) include the Company and/or GYP III (or any of the directors of the Company and/or GYP III) and AEA and (i) in the good faith judgment of AEA the use of joint counsel would present such counsel with an actual or potential conflict of interest or (ii) AEA shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company and/or GYP III (or the director(s)).  The Company and GYP III shall not be liable to indemnify any person for any settlement of any claim or action effected without written consent of the Company and GYP III, which consent shall not be unreasonably withheld.  In addition, the Company and GYP III hereby agree to reimburse AEA and each other Indemnified Person for all expenses (including reasonable fees and disbursements of counsel if the Company and/or GYP III does not assume the defense of such action) as they are incurred by AEA or any Indemnified Person in connection with investigating, preparing for or defending any such action or claim.  AEA shall have no liability to the Company and GYP III, any of their respective subsidiaries or affiliates or any of their respective directors, officers or employees in connection with the services which AEA renders pursuant to this Agreement, except for AEA’s bad faith, gross negligence or willful misconduct judicially determined as aforesaid.

In addition to the foregoing, the Company and GYP III hereby acknowledge that certain of the Indemnified Persons may have rights to indemnification, advancement of expenses and/or insurance provided by certain of their respective affiliates (collectively, the “Fund Indemnitors”).  The Company and GYP III hereby agree that (i) they are the indemnitor of first resort (i.e., their obligations to the Indemnified Persons are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same payment of expenses or liabilities incurred by any Indemnified Person are secondary), and (ii) no payment by the Fund Indemnitors on behalf of any Indemnified Person with respect to any claim for which such Indemnified Person has sought indemnification from the Company and/or GYP III hereunder shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or subrogation to the extent of payment to all of the rights of recovery of such Indemnified Person against the Company and/or GYP III.  The Company, GYP III and the Indemnified Persons agree that the Fund Indemnitors are express and intended third party beneficiaries of this paragraph.

The indemnification, contribution and expense reimbursement obligations the Company and GYP III have pursuant to this Annex A shall be in addition to any liability the Company and GYP III may otherwise have.  Any right to trial by jury with respect to any action or proceeding arising in connection with or as a result of either

A-2

AEA’s engagement or any matter referred to in this Agreement is hereby waived by the parties hereto.  The provisions of this Annex A shall survive any termination or completion of the engagement provided by this Agreement.
