6. Representations and Warranties of Buyer.

     Each Buyer, severally and not jointly, hereby represents and warrants to Seller, as of the date of this Purchase Agreement, as follows:

     (a) Authorization. Such Buyer is an entity duly organized and validly existing in good standing under the laws of its jurisdiction of organization. Such Buyer has the requisite power and authority to enter into, execute and deliver this Purchase Agreement and each of the Additional Buyers’ Documents and to perform all of the obligations to be performed by it hereunder and thereunder. This Purchase Agreement and the transactions contemplated hereby have been, and each of the Additional Buyers’ Documents will have been at the Closing, duly authorized, executed and delivered by it, and this Purchase Agreement constitutes, and each of the Additional Buyers’ Documents will constitute at the Closing, its valid and binding obligation, enforceable against it in accordance with its respective terms, subject to applicable bankruptcy,

insolvency, reorganization and moratorium laws and other laws of general application affecting enforcement of creditors’ rights generally.

     (b) No Conflicts. Neither the execution and delivery of this Purchase Agreement or the Additional Buyers’ Documents nor the performance or consummation of the transactions contemplated hereby or thereby by such Buyer will conflict with, result in the breach of, constitute a default under or accelerate the performance required by the terms of: (i) any law, rule or regulation of any government or governmental or regulatory agency; (ii) any judgment, order, writ, decree, permit or license of any court or governmental or regulatory agency to which such Buyer may be subject; (iii) any contract, agreement, commitment or instrument to which such Buyer is a party or by which it or any of its assets is bound; or (iv) such Buyer’s constituent documents or other governing instruments (or constitute an event which, with the passage of time or action by a third party, would result in any of the foregoing). The execution and delivery of this Purchase Agreement by such Buyer and the performance and consummation of the transactions contemplated hereby do not require any registration, filing, qualification, consent or approval under any such law, rule, regulation, judgment, order, writ, decree, permit or license to which such Buyer may be subject.

     (c) Valuation. Such Buyer understands that, by reason of certain of Seller’s relationships or those of its Affiliates, Seller may have information that is material to the valuation of the Interests and that has not been disclosed to such Buyer. Such Buyer acknowledges that Seller has no obligation to disclose such information to such Buyer, such Buyer is a sophisticated investor and has knowledge and experience in financial and business matters and expertise in assessing interests such as the Interests. Such Buyer understands that the valuation of interests such as the Interests is complex and subject to differences of opinion. Such Buyer has relied exclusively on its own sources of information, and has not relied on Purchaser or any of its Affiliates in order to evaluate the value of the Interests, and such Buyer believes that the purchase price to be paid by it in consideration for the transfer of the portion of the Interests it is purchasing pursuant to this Agreement is fair and that such purchase price together with the assumption of obligations by such Buyer provided for in this Purchase Agreement constitutes reasonably equivalent value for the portion of the Interests being purchased by it. Such Buyer understands that the Purchase Price for the Interests is the result of negotiations between Seller and the Buyers (with each taking into account such factors as it deems appropriate), and that the Purchase Price is not reflective of any valuation of the Interests (or any portion thereof) by any Affiliate of Seller, which Affiliate may value the Interests (or any portion thereof) at higher or lower amount depending on the purpose and context of such valuations.

     (d) Acknowledgments. Such Buyer is acquiring the portion of the Interests being purchased by it for such Buyer’s own account, for investment and not with a view to the distribution or resale thereof, except in compliance with the Act and applicable state securities laws. Such Buyer has evaluated the merits and risks of purchasing the portion of the Interests to be purchased by it on the terms set forth in this Purchase Agreement on its own and without reliance upon Seller except as set forth herein, and has such knowledge and experience in financial and business matters and in making investments of this type that it is capable of evaluating the merits and risks of such purchase. Such Buyer is an “accredited investor,” as that term is defined in Rule 501(a) of Regulation D under the Act, and a “qualified purchaser,” as that

term is defined in Section 2(a)(51) of the Investment Company Act of 1940.

     (e) Sufficient Funds. Such Buyer has available funds in cash sufficient for the payment of the Purchase Price on the Closing Date.

     (f) Brokers. Such Buyer has not, directly or indirectly, dealt with anyone acting in the capacity of a finder or broker and has not incurred any obligations for any finder’s or broker’s fee or commission in connection with the transactions contemplated by this Purchase Agreement.

     (g) Litigation. There is no action, suit, claim, proceeding, arbitration, governmental inquiry or investigation pending or, to such Buyer’s knowledge, threatened against such Buyer, at law or in equity, before or by any court, governmental or regulatory department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, if adversely determined, would question the validity of, or prevent the consummation of, the transactions contemplated by this Purchase Agreement or materially and adversely affect such Buyer’s ability to acquire the portion of the Interests to be purchased by it hereunder. There is no action or suit by such Buyer pending or threatened against any other person or entity relating to the Interests, the Feeder LLC, the General Partner, the Partnership or any GCP Fund.

     (h) Compliance with Law. Such Buyer’s acquisition and holding of the Interests will in all material respects be in compliance with all applicable laws, rules, regulations and other requirements of all governmental authorities or agencies having jurisdiction over such Buyer. The monies used to fund Buyer’s acquisition and funding of the Interests were such Buyer’s own monies and were not derived from or related in any way to any illegal activity. Neither such Buyer nor any Affiliate thereof nor, to such Buyer’s knowledge, any director or officer of either such Buyer or any Affiliate, (i) is, or is owned or controlled by an individual or entity that is, (A) currently named on the List of Specially Designated Nationals and Blocked Persons maintained by OFAC or otherwise the subject of any sanctions administered by OFAC or (B) located, organized or resident in a country or territory that is currently the subject of OFAC-administered sanctions, (ii) has been convicted of or charged with a felony relating to money laundering or other illegal activity, or (iii) is under investigation by any governmental authority for money laundering or any other illegal activity.

Notwithstanding anything in Paragraph 11(b) to the contrary, (A) no Buyer shall be obligated to provide indemnification for Losses in respect of claims made by Seller for indemnification under Paragraph 11(b)(i) and 11(b)(ii) above unless the total of all Losses in respect of claims made by Seller for indemnification against such Buyer shall exceed the Threshold in the aggregate, whereupon the total amount of such Losses from the Threshold shall be recoverable by Seller in accordance with the terms hereof and (B) the maximum amount payable by such Buyer to Seller for Losses in respect of claims made by Seller for

indemnification with respect to the breach of any representations or warranties hereunder with respect to the Interests shall not exceed 100% of the purchase price actually paid by such Buyer to Seller in respect to the portion of the Interests purchased by such Buyer hereunder; provided, however, that Seller shall not be subject to any limitation pursuant to this Paragraph 11(c)(ii) or otherwise, and shall be entitled to full recovery from such Buyer for Losses in connection with (x) fraud, intentional misrepresentation or a deliberate or willful breach by such Buyer of any of its representations and warranties under this Purchase Agreement and (y) liabilities assumed by such Buyer pursuant to Paragraph 3(e) of this Purchase Agreement.

     (d) Procedure for Third Party Claims.

          (i) If a Person entitled to assert a claim for indemnification under this Purchase Agreement shall receive written notice of the assertion by any Person not a party to this Purchase Agreement of any claim or of the commencement of any action or proceeding (a “Third Party Claim”) with respect to which either Seller or any Buyer is obligated to provide indemnification, the indemnified party (the “Indemnitee”) shall give the indemnifying party (the “Indemnitor”) prompt written notice after becoming aware of such Third Party Claim. The failure of the Indemnitee to give notice as provided in this paragraph shall not relieve the Indemnitor of its obligations for indemnification under this Purchase Agreement, except to the extent that the failure has materially and adversely affected the rights of the Indemnitor. The notice from the Indemnitee shall describe the Third Party Claim in reasonable detail.

          (ii) An Indemnitor may elect to compromise or defend, at the Indemnitor’s own expense and by the Indemnitor’s own counsel, any Third Party Claim. If an Indemnitor elects to compromise or defend a Third Party Claim, it shall, within thirty (30) days (or sooner, if the nature of the Third Party Claim so requires), notify the Indemnitee in writing of its intent to do so, and the Indemnitee shall cooperate in the compromise of, or defense against, the Third Party Claim. The Indemnitor shall pay the Indemnitee’s actual out-of-pocket expenses incurred in connection with its cooperation. After notice from an Indemnitor to an Indemnitee of its election to assume the defense of a Third Party Claim, the Indemnitor shall not be liable to the Indemnitee under this Purchase Agreement for any legal expenses subsequently incurred by the Indemnitee in connection with defense of the Third Party Claim; provided that Indemnitee shall have the right to employ one counsel to represent Indemnitee if, in the Indemnitee’s reasonable judgment, a conflict of interest between the Indemnitee and the Indemnitor exists in respect of such Third Party Claim, and in that event the fees and expenses of such separate counsel shall be paid by the Indemnitor. If an Indemnitor elects not to defend against a Third Party Claim, or fails to notify an Indemnitee of its election as provided in this paragraph, the Indemnitee may pay, compromise or defend such Third Party Claim on behalf of, and for the account and risk of, the Indemnitor (and the costs so incurred shall constitute indemnifiable Losses under Paragraphs 11(a) and 11(b), as applicable), provided that no Indemnitee shall consent to entry of any judgment or enter into any settlement, except with the written consent of the Indemnitor (which consent shall not be unreasonably withheld or delayed). No Indemnitor shall consent to entry of any judgment or enter into any settlement, except with the written consent of each affected Indemnitee (which consent shall not be unreasonably withheld or delayed), if such judgment or settlement provides for anything other than money damages or other money payments for which the Indemnitee is entitled to indemnification under this Purchase Agreement or which does not contain as an unconditional term thereof the giving by the claimant or plaintiff

to the Indemnitee of a release from all liability in respect of the Third Party Claim. Any indemnification payment shall be treated for tax purposes as an adjustment to the applicable portion of the Purchase Price, to the extent permitted under applicable law.

          (iii) If there is a reasonable likelihood that a Third Party Claim may materially and adversely affect an Indemnitee, other than as a result of money damages or other money payments for which the Indemnitee is entitled to indemnification hereunder, the Indemnitee will have the right, after consultation with the Indemnitor and at the cost and expense of the Indemnitor, to assume the defense of the Third Party Claim in lieu of the Indemnitor with counsel reasonably acceptable to the Indemnitor. No Indemnitee shall consent to entry of any judgment or enter into any settlement, except with the written consent of each Indemnitor (which consent shall not be unreasonably withheld or delayed).

     (e) Procedure for Non-Third Party Claims. With respect to any claim for indemnification hereunder which does not result from a Third Party Claim, the Indemnitor shall have a period of thirty (30) days after receipt of notice from the Indemnitee within which to respond to the Indemnitee. If the Indemnitor does not respond within the thirty (30) day period, the Indemnitor shall be deemed to have accepted responsibility to make payment and shall have no further right to contest the validity of such claim. If the Indemnitor does respond within the thirty (30) day period and rejects the claim in whole or in part, the Indemnitee shall be free to pursue such remedies as may be available to the Indemnitee under this Purchase Agreement or applicable law.

     (f) Reduction of Claim or Loss. If the amount of any Claim or Loss shall, at any time subsequent to payment pursuant to this Paragraph 11, be reduced by recovery, settlement or otherwise, the amount of such reduction, less any expenses incurred in connection therewith, shall promptly be repaid by the Indemnitee to the related Indemnitor.

     (g) Certain Damages Excluded. Neither any Buyer nor Seller shall be liable to each other for punitive damages or Losses that are indirect, remote, speculative or not reasonably foreseeeable in connection with its indemnification obligations under this Paragraph 11.

     (h) Remedies Exclusive. Subject to the other provisions of this Purchase Agreement, the remedies provided in this Paragraph 11 shall be the sole and exclusive remedy against a party for Losses, provided however, that notwithstanding the foregoing, nothing in this Paragraph 11(h) shall limit in any way any remedy at law or equity to which a party may be entitled as a result of fraud or intentional misrepresentation or deliberate and willful breach by the other party of any of their representations and warranties under this Purchase Agreement, the Schedules to it, the Additional Seller’s Documents or the Additional Buyers’ Documents, as appropriate.

     (i) Any amount paid by Seller or any Buyer pursuant to Paragraph 11(a) or 11(b) shall be treated as an adjustment to the Purchase Price for all tax purposes.

12. Confidentiality.

     (a) Except (i) as required or expressly permitted by this Agreement, (ii) as may be necessary in order to give the notices to obtain any prior regulatory approval or the Approvals,

(iii) as necessary to consult with attorneys, accountants, employees, or other advisors retained in connection with the transactions contemplated hereby (which persons shall be notified of the confidential nature of such information prior to such disclosure), (iv) as required by court order or otherwise mandated by law or regulation, (v) is required to be disclosed in any document to be filed with any federal, state, municipal or other governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, or in connection with any litigation, or (vi) in connection with disclosure documents prepared by Seller or any of its Affiliates, no party to this Agreement shall issue any news release or other public notice or communication or otherwise make any disclosure to third parties concerning this Agreement or the transactions contemplated hereby, without the prior written consent of the other party (which consent shall not be unreasonably withheld or delayed). Even in cases where such prior consent is not required, Buyers and Seller shall, to the extent permitted by law or regulation, promptly notify the other party of such release in advance in order to provide a reasonable opportunity to the other party to prepare a corresponding or other similar release or other action on a timely basis. Without the consent of the other, neither any Buyer nor Seller shall disclose the Purchase Price to any Person, except that such disclosure may be made (i) to officers, directors, members, partners and their investors, members, advisors and employees of any Buyer or Seller and as necessary to consult with attorneys, accountants, employees or other advisors retained in connection with the transactions contemplated hereby (which persons shall be notified of the confidential nature of such information prior to such disclosure) and (ii) as required by law or by the Interest Agreements (including without limitation in connection with rights of first refusal or other similar rights). Notwithstanding the foregoing provisions of this Paragraph 12(a), from and after the Closing, Seller and each Buyer may make disclosure concerning this Agreement and the transactions consummated at the Closing to its Affiliates, partners, members, officers, directors, employees, agents, accountants, attorneys and other parties who have a need to know such information (which persons shall be notified of the confidential nature of such information prior to such disclosure).

     (b) Notwithstanding anything else contained in this Purchase Agreement, each Buyer and Seller (and their respective member, partners, employees, representatives or other agents) may disclose to any and all Persons, without limitation of any kind, the tax treatment and tax structure (as such terms are used in Sections 6011, 6111 and 6112 of the Code and the U.S. Treasury Regulations promulgated thereunder) of this Purchase Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to such Buyer or Seller relating to such tax treatment and tax structure; provided, that none of the foregoing or their members, partners, employees, representatives or agents shall disclose any information for which nondisclosure is reasonably necessary in order to comply with U.S. securities laws; and provided further that this authorization is not intended to permit disclosure of any term or detail (including but not limited to the Purchase Price or the name or other identifying information of any Buyer or Seller) not relevant to the tax treatment or the tax structure of this Agreement.

13. Termination.

     (a) By Mutual Consent. This Purchase Agreement may be terminated and the transactions contemplated by it abandoned for any reason pursuant to the mutual written consent of Buyers and Seller and, thereupon, Buyers shall have no further obligation to purchase and Seller shall have no further obligations to sell, any of the Interests.

     (b) By Buyers or Seller. This Purchase Agreement may be terminated and the transactions contemplated by it abandoned by written notice from Buyers to Seller, or from Seller to Buyers, (i) in the event of a material breach by Seller or any Buyer, respectively, of any representation, warranty, covenant or agreement contained in this Purchase Agreement which cannot be or is not cured within ten (10) business days (a “Cure Period”) after written notice of the breach is given to the party committing the breach; or (ii) if the Closing does not occur on or before the Closing Deadline (or such later date as may be agreed upon in writing by Buyers and Seller); provided, however, that the right to terminate this Purchase Agreement under the foregoing clause (ii) shall not be available to a party if such party’s breach of this Purchase Agreement has been the cause of or resulted in the failure of the Closing to occur on or before the Closing Deadline, it being understood and agreed that a failure to satisfy any of the conditions set forth in Paragraphs 8(c) and 9(c) shall not be deemed a “breach or failure to fulfill any obligation” by any party.

     (c) Survival. If this Purchase Agreement is terminated, no party to this Purchase Agreement will have any liability or further obligation to the other party pursuant to this Purchase Agreement; provided, however, that (i) nothing herein shall relieve a party for a breach of this Purchase Agreement occurring prior to such termination; (ii) the agreements of Seller and Buyers contained in Paragraphs 12 and 15(a) shall survive such termination; and (iii) if termination results from the bad faith or willful breach by a party, such party will remain liable for any and all costs, expenses, damages incurred or suffered by the other party as a direct result of such failure or breach.

14. Post Closing Covenants.

     (a) Notices; Distributions. From and after the Closing, Seller shall promptly forward to Buyers any correspondence, notices or distributions (in cash or otherwise) received by Seller or any affiliated entity that relate to the Interests. Seller shall remit any distributions in cash, securities or other property pursuant to the preceding sentence to Buyers within fifteen (15) business days after receipt by Seller. If Seller fails to remit any distributions pursuant to the preceding sentence to Buyers within such time period, in addition to any other rights and remedies Buyer may have, Buyer may assess interest (at the Prime Rate as reported in The Wall Street Journal) on the unpaid amount commencing on such fifteenth business day after receipt.

     (b) Tax Information. In the event either the Feeder LLC, the Partnership or the General Partner is an “electing investment partnership” under Section 743(e)(6) of the Code for the taxable year that includes the Closing Date, Seller agrees to furnish to each Buyer all information with respect to such entity reasonably necessary to enable such Buyer to compute the amount of its losses (if any) disallowed under Section 743(e) of the Code. Such information shall be furnished in compliance with the requirements of IRS Notice 2005-32 or superseding

guidance issued by the Internal Revenue Service.

15. General Provisions.

     (a) Expenses. Except as provided in Paragraph 7(b)(iii) and in the following sentence, all fees and expenses incurred in connection with this Purchase Agreement (and the transactions contemplated hereunder), including all fees of counsel and accountants, shall be borne by the party incurring the same. All attorneys’ and accountants’ fees of the Feeder LLC or Manager payable as a result of the transfer of the Interests or any part thereof, including any accounting, tax preparation or other administrative expenses incurred by the Feeder LLC and charged to a Buyer or Seller in connection with the transfer of such Interests, shall be borne in equal shares by the applicable Buyer, on the one hand, and Seller, on the other hand.

     (b) Notices. All notices, requests, demands and other communications required or permitted under this Purchase Agreement shall be in writing and shall be deemed to have been duly given and received when delivered by hand or courier, when received by electronic mail or facsimile transmission, or three (3) days after the date when posted by U.S. mail, with postage prepaid, addressed as follows:

	(i)		If to Seller, to:
			Greenhill Capital Partners, LLC 300 Park Avenue New York, NY 10022 Attn: General Counsel ***@*** Facsimile: (212)  ###-###-####

or to such other person or address as Seller shall furnish to Buyers in writing.

	(ii)		If to a Buyer, to such Buyer:
			c/o J.P. Morgan Investment Management Inc. 245 Park Avenue New York, NY 10167 Attn: Mr. Jarrod Fong           Mr. Julian Shles ***@*** ***@*** Facsimile: (212)  ###-###-####

or to such other person or address as any Buyer shall furnish to Seller in writing.

     (c) Assignment. This Purchase Agreement and all of its provisions shall be binding upon and inure to the benefit of the parties and their respective successors and assigns. This Purchase Agreement may not be assigned without the prior written consent of each of the parties hereto.

     (d) Governing Law and Jurisdiction. This Purchase Agreement and the legal relations among the parties shall be governed by and construed in accordance with the laws of the State of New York without reference to the conflicts of laws principles thereof. Any dispute, controversy or claim arising out of or in connection with this Purchase Agreement or the breach, termination or invalidity thereof, may be brought in the United States District Court for the Southern District of New York or any New York state court sitting in New York County and, by execution and delivery of this Purchase Agreement, each of the parties hereto accepts the exclusive jurisdiction of such court, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Purchase Agreement.

     (e) Counterparts. This Purchase Agreement may be executed in two or more identical counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile or portable document format (PDF) copies of this Purchase Agreement shall have the same force and effect as an original.

     (f) Interpretation. The headings of the paragraphs and subparagraphs of this Purchase Agreement are inserted for convenience only and shall not constitute a part of or affect in any way the meaning or interpretation of this Purchase Agreement. The words “include,” “includes” and “including” when used in this Purchase Agreement shall be deemed in each case to be followed by the words “without limitation.” Defined terms used in this Purchase Agreement shall have the same meaning whether defined or used herein in the singular or the plural, as the case may be.

     (g) Entire Agreement. This Purchase Agreement, including the Schedules to this Purchase Agreement, and the other documents and certificates delivered pursuant to the terms of this Purchase Agreement set forth the entire agreement and understanding of the parties with respect to the subject matter of this Purchase Agreement and supersede all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of any party.

     (h) Amendment; Waiver. This Purchase Agreement may be amended only by a written instrument executed by Seller and Buyers. Any failure of any Buyer to comply with any obligation, agreement or condition under this Purchase Agreement may only be waived in writing by Seller, and any such failure by Seller may only be waived in writing by Buyers, but any such waiver shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. No failure by a party to take any action against any breach of this Purchase Agreement or default by the other party shall constitute a waiver of such party’s right to enforce any provision of this Purchase Agreement or to take any such action.

     (i) Third Parties. Except as specifically set forth or referred to in this Purchase Agreement, nothing in this Purchase Agreement, expressed or implied, is intended, or shall be construed, to confer upon or give to any Person other than the parties and their successors or assigns, any rights or remedies under or by reason of this Purchase Agreement.

     (j) Additional Documents and Acts. Each of the parties agrees to execute and deliver such additional documents, certificates and instruments, and to perform such additional acts, as may be reasonably requested and as may be necessary or appropriate to carry out the provisions

of this Purchase Agreement and to consummate the transactions contemplated by this Purchase Agreement.

     (k) Specific Performance. Buyers, on the one hand, and Seller, on the other hand, hereby acknowledge and agree that money damages would not be a sufficient remedy for any breach of any covenant or agreement provided in this Purchase Agreement. In such event, each party agrees that the other party shall have the right, in addition to any other rights it may have (whether in law or in equity) to specific performance and/or injunctive or other equitable relief as a remedy for such breach of this Purchase Agreement without the necessity of posting any bond and without the necessity of establishing that monetary relief would not provide an adequate remedy. No failure or delay by any party hereto in exercising any right, power or privilege hereunder will operate as a waiver thereof, nor will any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

     (l) Severability. If any term, provision, agreement, covenant or restriction of this Purchase Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, or unenforceable, the remainder of the terms, provisions, agreements, covenants and restrictions of this Purchase Agreement shall remain in full force and effect and shall in no way be affected, impaired, or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such a determination, the parties shall negotiate in good faith to modify this Purchase Agreement so as to effect the original intent of the parties as closely as possible in a reasonably acceptable manner in order that the transactions contemplated hereby may be consummated as originally contemplated to the fullest extent possible.

     (m) Waiver of Jury Trial. EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION AS BETWEEN THE PARTIES DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS PURCHASE AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR DISPUTES RELATING THERETO.
