(c) Without limiting the foregoing, in the event that any Proceeding is initiated by an Indemnitee or any member of the Company Group to enforce or interpret this Agreement or any rights of such Indemnitee to indemnification or advancement of expenses (or related Obligations of such Indemnitee) under any member of the Company Group’s certificate of incorporation or bylaws (or similar organizational documents), any other agreement to which such Indemnitee and any member of the Company Group are party, any vote of directors of any member of the Company Group, the law of incorporation or formation of any member of the Company Group or any other applicable law or any liability insurance policy, the Indemnifying Parties shall indemnify such Indemnitee against all costs and Expenses incurred by such Indemnitee or on such Indemnitee’s behalf in connection with such Proceeding, whether or not such Indemnitee is successful in such Proceeding, except to the extent that the court presiding over such Proceeding determines that material assertions made by such Indemnitee in such proceeding were in bad faith.

(d) (i) Each of the Company Entities acknowledges and agrees that the obligations of the Indemnifying Parties under this Agreement, any Related Document or any Company Director Indemnity to indemnify or advance expenses to any Investor Director for the matters covered thereby shall be the primary source of indemnification and advancement of such Investor Director in connection therewith, and any obligation on the part of any Investor Indemnitor under any Investor Indemnification Agreement to indemnify or advance expenses to such Investor Director shall be secondary to the Indemnifying Party’s obligation and shall be reduced by any amount that the Investor Director may collect as indemnification or advancement from the Indemnifying Party. In the event that the Indemnifying Party fails to indemnify or advance expenses to an Investor Director as required or contemplated by this Agreement, any Related Document or any Company Director Indemnity, and any Investor Indemnitor makes any payment to such Investor Director in respect of indemnification or advancement of expenses under any Investor Indemnification Agreement on account of such Unpaid Director Indemnity Amounts, such Investor Indemnitor shall be subrogated to the rights of such Investor Director under this Agreement, any Related Document or any Company Director Indemnity, as the case may be, in respect of such Unpaid Director Indemnity Amounts.

Director under this Agreement, any Related Documents or any Company Director Indemnity.

(e) The rights, indemnities and remedies herein provided are cumulative and are not exclusive of any rights, indemnities or remedies that any party or other Indemnitee may otherwise have by contract, at law or in equity or otherwise, provided that (i) to the extent that any Indemnitee is entitled to be indemnified by any Company Entity and by any other Indemnitee or any insurer under a policy procured by any Indemnitee, the obligations of the Company Entity hereunder shall be primary and the obligations of such other Indemnitee or insurer secondary, and (ii) none of the Company Entities shall be entitled to contribution or indemnification from or subrogation against such other Indemnitee or insurer.

3. Contribution.

(a) If for any reason the indemnity provided for in Section 2(a) is unavailable or is insufficient to hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then the Indemnifying Parties, jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such proportion as is appropriate to reflect (i) the relative fault of each member of the Company Group and their Agents, on the one hand, and such Indemnitee, on the other, in connection with the state of facts giving rise to such Obligation, (ii) if such Obligation results from, arises out of, is based upon or relates to any Transaction or any Securities Offering, the relative benefits received by each member of the Company Group and their Agents, on the one hand, and such Indemnitee, on the other, from such Transaction or Securities Offering and (iii) if required by applicable law, any other relevant equitable considerations.

(b) If for any reason the indemnity specifically provided for in Section 2(b) is unavailable or is insufficient to hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then the Indemnifying Parties, jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such proportion as is appropriate to reflect (i) the relative fault of each of the members of the Company Group and their Agents, on the one hand, and such Indemnitee, on the other, in connection with the information contained in or omitted from any Related Document, which inclusion or omission resulted in the inaccuracy or breach of or default under any representation, warranty, covenant or agreement therein, or which information is or is alleged to be untrue, required to be stated therein or necessary to make the statements therein not misleading, (ii) the relative benefits received by the members of the Company Group and their Agents, on the one hand, and such Indemnitee, on the other, from such Transaction or Securities Offering and (iii) if required by applicable law, any other relevant equitable considerations.

(c) For purposes of Section 3(a), the relative fault of each member of the Company Group and their Agents, on the one hand, and of an Indemnitee, on the other,

shall be determined by reference to, among other things, their respective relative intent, knowledge, access to information and opportunity to correct the state of facts giving rise to such Obligation. For purposes of Section 3(b), the relative fault of each of the members of the Company Group and their Agents, on the one hand, and of an Indemnitee, on the other, shall be determined by reference to, among other things, (i) whether the included or omitted information relates to information supplied by the members of the Company Group and their Agents, on the one hand, or by such Indemnitee, on the other, (ii) their respective relative intent, knowledge, access to information and opportunity to correct such inaccuracy, breach, default, untrue or alleged untrue statement, or omission or alleged omission, and (iii) applicable law. For purposes of Section 3(a) or 3(b), the relative benefits received by each member of the Company Group and their Agents, on the one hand, and an Indemnitee, on the other, shall be determined by weighing the direct monetary proceeds to the Company Group, on the one hand, and such Indemnitee, on the other, from such Transaction or Securities Offering.

(d) The parties hereto acknowledge and agree that it would not be just and equitable if contributions pursuant to Section 3(a) or 3(b) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in such respective Section. No Indemnifying Party shall be liable under Section 3(a) or 3(b), as applicable, for contribution to the amount paid or payable by any Indemnitee except to the extent and under such circumstances such Indemnifying Party would have been liable to indemnify, defend and hold harmless such Indemnitee under the corresponding Section 2(a) or 2(b), as applicable, if such indemnity were enforceable under applicable law. No Indemnitee shall be entitled to contribution from any Indemnifying Party with respect to any Obligation covered by the indemnity specifically provided for in Section 2(b) in the event that such Indemnitee is finally determined to be guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such Obligation and the Indemnifying Parties are not guilty of such fraudulent misrepresentation.

4. Indemnification Procedures.

(a) Whenever any Indemnitee shall have actual knowledge of the assertion of a Claim against it, such Indemnitee shall notify the appropriate member of the Company Group in writing of the Claim (the “Notice of Claim”) with reasonable promptness after such Indemnitee has such knowledge relating to such Claim; provided the failure or delay of such Indemnitee to give such Notice of Claim shall not relieve any Indemnifying Party of its indemnification obligations under this Agreement except to the extent that such omission results in a failure of actual notice to it and it is materially injured as a result of the failure to give such Notice of Claim. The Notice of Claim shall specify all material facts known to such Indemnitee relating to such Claim and the monetary amount or an estimate of the monetary amount of the Obligation involved if such Indemnitee has knowledge of such amount or a reasonable basis for making such an estimate. The Indemnifying Parties shall, at their expense, undertake the defense of such Claim with

attorneys of their own choosing reasonably satisfactory in all respects to such Indemnitee, subject to the right of such Indemnitee to undertake such defense as hereinafter provided. An Indemnitee may participate in such defense with counsel of such Indemnitee’s choosing at the expense of the Indemnifying Parties. In the event that the Indemnifying Parties do not undertake the defense of the Claim within a reasonable time after such Indemnitee has given the Notice of Claim, or in the event that such Indemnitee shall in good faith determine that the defense of any claim by the Indemnifying Parties is inadequate or may conflict with the interest of any Indemnitee (including Claims brought by or on behalf of any member of the Company Group), such Indemnitee may, at the expense of the Indemnifying Parties and after giving notice to the Indemnifying Parties of such action, undertake the defense of the Claim and compromise or settle the Claim, all for the account of and at the risk of the Indemnifying Parties. In the defense of any Claim against an Indemnitee, no Indemnifying Party shall, except with the prior written consent of such Indemnitee, consent to entry of any judgment or enter into any settlement that includes any injunctive or other non-monetary relief or any payment of money by such Indemnitee, or that does not include as an unconditional term thereof the giving by the Person or Persons asserting such Claim to such Indemnitee of an unconditional release from all liability on any of the matters that are the subject of such Claim and an acknowledgement that such Indemnitee denies all wrongdoing in connection with such matters. The Indemnifying Parties shall not be obligated to indemnify an Indemnitee against amounts paid in settlement of a Claim if such settlement is effected by such Indemnitee without the prior written consent of Parent (on behalf of all Indemnifying Parties), which shall not be unreasonably withheld. In each case, each Indemnitee seeking indemnification hereunder will cooperate with the Indemnifying Parties, so long as an Indemnifying Party is conducting the defense of the Claim, in the preparation for and the prosecution of the defense of such Claim, including making available evidence within the control of such Indemnitee, as the case may be, and persons needed as witnesses who are employed by such Indemnitee, as the case may be, in each case as reasonably needed for such defense and at cost, which cost, to the extent reasonably incurred, shall be paid by the Indemnifying Parties.

(b) An Indemnitee shall notify the Indemnifying Parties in writing of the amount requested for advances (“Notice of Advances”). The Indemnifying Parties hereby agree to advance reasonable costs and Expenses incurred by any Indemnitee in connection with any Claim (but not for any Claim initiated or brought voluntarily by an Indemnitee other than a Proceeding pursuant to Section 2(c)) in advance of the final disposition of such Claim without regard to whether such Indemnitee will ultimately be entitled to be indemnified for such costs and expenses upon receipt of an undertaking by or on behalf of such Indemnitee to repay amounts so advanced if it shall ultimately be determined in a decision of a court of competent jurisdiction from which no appeal can be taken that such Indemnitee is not entitled to be indemnified by the Indemnifying Parties as authorized by this Agreement. The Indemnifying Parties shall make payment of such advances no later than 10 days after the receipt of the Notice of Advances.

(c) An Indemnitee shall notify the Indemnifying Parties in writing of the amount of any Claim actually paid by such Indemnitee (the “Notice of Payment”). The amount of any Claim actually paid by such Indemnitee shall bear simple interest at the rate equal to the JPMorgan Chase Bank, N.A. prime rate as of the date of such payment plus 2% per annum, from the date the Indemnifying Parties receive the Notice of Payment to the date on which any Indemnifying Party shall repay the amount of such Claim plus interest thereon to such Indemnitee. The Indemnifying Parties shall make indemnification payments to such Indemnitee no later than 30 days after receipt of the Notice of Payment.

(d) Independent Legal Counsel. If there has not been a Change in Control, independent legal counsel shall be selected by the board of directors of Parent and approved by such Indemnitee (which approval shall not be unreasonably withheld or delayed). If there has been a Change in Control, independent legal counsel shall be selected by such Indemnitee and approved by Parent (which approval shall not be unreasonably withheld or delayed). The Indemnifying Parties shall pay the fees and expenses of such independent legal counsel and indemnify such independent legal counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to its engagement.

5. Certain Covenants.

(a) The rights of each Indemnitee to be indemnified under any other agreement, document, certificate or instrument or applicable law are independent of and in addition to any rights of such Indemnitee to be indemnified under this Agreement and, to the extent applicable, subject to Section 2(d). The rights of each Indemnitee and the obligations of the Indemnifying Parties hereunder shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnitee. Following the Transactions, each of the Company Entities, and each of their corporate successors, shall implement and maintain in full force and effect any and all corporate charter and by-law (or similar organizational document) provisions that may be necessary or appropriate to enable it to carry out its obligations hereunder to the fullest extent permitted by applicable law, including a provision of its certificate of incorporation (or similar organizational document) eliminating liability of a director for breach of fiduciary duty to the fullest extent permitted by applicable law, as amended from time to time. So long as Parent or any other member of the Company Group maintains liability insurance for any directors, officers, employees or agents of any such Person, the Indemnifying Parties shall ensure that each Indemnitee serving in such capacity is covered by such insurance in such a manner as to provide such Indemnitee the same rights and benefits as are accorded to the most favorably insured of Parent’s and the Company Group’s then current directors and officers.

(b) Each of Aggregator LP, Parent and the Company hereby agrees that it will not amend (and will cause each other member of the Company Group not to amend) any

Company Director Indemnity as in effect on the date hereof to alter the rights of any Investor Director in any manner that would alter any Investor Director’s rights with respect to conduct pre-dating the date of any such amendment without the consent of the Manager.

7. Governing Law; Jurisdiction, Waiver of Jury Trial. This Agreement shall be governed in all respects, including validity, interpretation and effect, by the law of the State of New York, regardless of the law that might be applied under principles of conflict of laws to the extent such principles would require or permit the application of the laws of another jurisdiction. Each of the parties hereto irrevocably and unconditionally (a) agrees that any legal suit, action or proceeding brought by any party hereto arising out of or based upon this Agreement or the transactions contemplated hereby may be brought in any court of the State of New York or Federal District Court for the Southern District of New York located in the City, County and State of New York (each, a “New York Court”), (b) waives, to the fullest extent that it may effectively do so, any objection that it may now or hereafter have to the laying of venue of any such proceeding brought in a New York Court, and any claim that any such action or proceeding brought in a New York Court has been brought in an inconvenient forum, (c) submits to the non-exclusive jurisdiction of any New York Court in any suit, action or proceeding and (d) ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE HEREBY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT. With respect to clause (d) of the immediately preceding sentence, each of the parties hereto acknowledges and certifies that (i) no representative, agent or attorney of any other party has represented, expressly or

otherwise, that such other party would not, in the event of litigation, seek to enforce the waiver contained therein, (ii) it understands and has considered the implications of such waiver, (iii) it makes such waiver voluntarily and (iv) it has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications contained in this Section 7. No Indemnifying Party shall seek any order of a court or other governmental authority that would prohibit or otherwise interfere with the performance of any of the Indemnifying Parties’ advancement, indemnification and other obligations under this Agreement.

8. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby.

9. Successors; Binding Effect. Each Indemnifying Party will require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business and assets of such Indemnifying Party, by agreement in form and substance satisfactory to the Manager and its counsel, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that such Indemnifying Party would be required to perform if no such succession had taken place. This Agreement shall be binding upon and inure to the benefit of each party hereto and its successors and permitted assigns, and each other Indemnitee, but neither this Agreement nor any right, interest or obligation hereunder shall be assigned, whether by operation of law or otherwise, by Parent, Aggregator LP or the Company without the prior written consent of the Manager.

10. Miscellaneous. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. This Agreement is not intended to confer any right or remedy hereunder upon any Person other than (i) each of the parties hereto and their respective successors and permitted assigns and (ii) each other Indemnitee and, with respect to the provisions of Section 5(b), the Investor Directors, all of whom are intended to be third party beneficiaries thereof. No amendment, modification, supplement or discharge of this Agreement, and no waiver hereunder shall be valid and binding unless set forth in writing and duly executed by the party or other Indemnitee against whom enforcement of the amendment, modification, supplement or discharge is sought. Neither the waiver by any of the parties hereto or any other Indemnitee of a breach of or a default under any of the provisions of this Agreement, nor the failure by any party hereto or any other Indemnitee on one or more occasions, to enforce any of the provisions of this Agreement or to exercise any right, powers or privilege hereunder, shall be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any provisions hereof, or any rights, powers or privileges hereunder. Subject to Section 2(d) hereof, the rights, indemnities and remedies herein provided are cumulative and are not exclusive of any rights, indemnities or remedies that any party or other Indemnitee may otherwise have by contract, at law or in equity or otherwise. This Agreement may be executed in several

counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument. Whenever the words “include”, “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.”

11. Information. Each of Aggregator LP, Parent and the Company hereby consents to the Investor Directors sharing any information such Investor Directors receive from any member of the Company Group with officers, directors, members, employees and representatives of the Manager and its Affiliates (other than other portfolio companies) and to the internal use by the Manager and its Affiliates of any information received from any member of the Company Group, subject, however, to the Manager maintaining adequate procedures to prevent such information from being used in connection with the purchase or sale of securities of any member of the Company Group in violation of applicable law.
