SECTION 3. General Representations and Warranties. The Borrower represents and warrants that:

(a) It has good and marketable title to all its Collateral, free and clear of any Lien other than Permitted Liens.

(b) It has not performed any acts that would reasonably be likely to prevent the Lender from enforcing any of the provisions of the Credit Documents or that would limit the Lender in any such enforcement. No financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or part of the Collateral owned by the Borrower is on file or of record in any jurisdiction in which such filing or recording would be effective to perfect or record a Lien on such Collateral. After the Closing Date, no Collateral owned by the Borrower will be in the possession or under the Control of any other Person having a claim thereto or security interest therein, other than a Permitted Lien.

(c) The Transaction Liens on all Collateral owned by the Borrower (i) have been validly created, (ii) will attach to each item of such Collateral on the Closing Date (or, if the Borrower first obtains rights thereto on a later date, on such later date) and (iii) when so attached, will secure all the Secured Obligations.

(d) It has delivered a Perfection Certificate to the Lender. The information set forth therein is correct and complete in all material respects as of the Closing Date.

6

(e) When UCC financing statements describing the Collateral as “all personal property” or “all assets” have been filed in the offices specified in such Perfection Certificate, the Transaction Liens will constitute perfected security interests in the Collateral owned by the Borrower to the extent that a security interest therein may be perfected by filing pursuant to the UCC, prior to all Liens and rights of others therein. Except for the filing of such UCC financing statements, no registration, recordation or filing with any governmental body, agency or official is required in connection with the execution or delivery of the Collateral Documents or is necessary for the validity or enforceability thereof or for the perfection or due recordation of the Transaction Liens or for the enforcement of the Transaction Liens.

SECTION 4. Further Assurances; General Covenants. The Borrower covenants as follows:

(a) It will, from time to time, at its own expense, execute, deliver, file and record any statement, assignment, instrument, document, agreement or other paper and take any other action (including any filing of financing or continuation statements under the UCC) that from time to time may be reasonably necessary or desirable, or that the Lender may reasonably request, in order to:

(i) create, preserve, perfect, confirm or validate the Transaction Liens on the Collateral;

(ii) in the case of any Collateral Account, cause the Lender to have Control thereof;

(iii) enable the Lender and the other Secured Parties to obtain the full benefits of the Credit Documents;

(iv) enable the Lender to exercise and enforce any of its rights, powers and remedies with respect to any of the Collateral (including, from time to time, duly execute and deliver to the Lender or the relevant assignee (as directed by the Lender) such Assignment Agreements and other documents and instruments determined by the Lender to be reasonably necessary to effect or evidence any assignment, purchase or other transfer of Bank Loans as the Lender may request).

To the extent permitted by applicable law, the Borrower authorizes the Lender to (A) execute and file such financing statements or continuation statements without the Borrower’s signature appearing thereon and, (B) upon the occurrence and during the continuance of an Event of Default, execute, deliver and complete, and seek required consents in respect of, any Assignment Agreement delivered by the Borrower with respect to any Bank Loan pursuant to Section 7. The Borrower

7

agrees that the Lender may utilize a carbon, photographic, photostatic or other reproduction of this Agreement or of a financing statement as a financing statement. The Borrower constitutes the Lender its attorney-in-fact to (1) execute and file all filings required or so requested for the foregoing purposes and, (2) upon the occurrence and during the continuance of an Event of Default, execute, deliver and complete, and seek required consents in respect of, any Assignment Agreement delivered by the Borrower with respect to any Bank Loan, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Transaction Liens granted by the Borrower terminate pursuant to Section 15. The Borrower will pay the costs of, or incidental to, any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto.

(b) The Borrower will not (i) change its name or corporate structure, (ii) change its location (determined as provided in UCC Section 9-307) or (iii) become bound, as provided in UCC Section 9-203(d) or otherwise, by a security agreement entered into by another Person, unless it shall have given the Lender prior notice thereof and delivered an Opinion of Counsel with respect thereto in accordance with Section 4(c).

(c) At least 30 days before it takes any action contemplated by Section 4(b), the Borrower will, at its own expense, cause to be delivered to the Lender an Opinion of Counsel, in form and substance satisfactory to the Lender, to the effect that (i) all financing statements and amendments or supplements thereto, continuation statements and other documents required to be filed or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from the Borrower after it takes such action (except any continuation statements specified in such Opinion of Counsel that are to be filed more than six months after the date thereof) have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any, payable in connection with such filings or recordations have been paid in full and (iii) except as otherwise agreed by the Lender, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral after it takes such action or the accuracy of the representations and warranties herein relating to such Collateral.

(d) It will notify the Lender as soon as it has knowledge or reasonable belief that the value of any Collateral has been or may be materially impaired (including as a result of a default or event of default occurring with respect to any Collateral).

(e) It will, promptly upon request, provide to the Lender all information and evidence concerning the Collateral that the Lender may reasonably request from time to time to enable it to enforce the provisions of the Collateral Documents.

8

(f) It agrees that any financing statement may contain an indication or description of the Collateral that describes such property in any manner as the Lender may determine, in its sole discretion, is necessary, advisable or prudent to ensure the perfection of the security interest in the Collateral granted to the Lender herein, including describing such property as “all assets, whether now owned or hereafter acquired” or “all personal property, whether now owned or hereafter acquired”.

(b) Perfection as to Security Entitlements. Upon the execution and delivery of the Custodial Agreement by the parties thereto, so long as any Financial Asset owned by the Borrower is credited to the Custodial Account, (i) the Transaction Lien on the Borrower’s Security Entitlement in respect of such Financial Asset will be perfected, subject to no Liens or rights of others (except Permitted Liens), (ii) the Lender will have Control of such Security Entitlement and (iii) no action based on an adverse claim to such Security Entitlement or such Financial Asset, whether framed in conversion, replevin, constructive trust, equitable lien or other theory, may be asserted against the Lender.

SECTION 8. Operation of Collateral Accounts.

(a) If an Event of Default shall have occurred and is continuing, the Lender may (i) instruct the Custodian to retain all cash and investments then held in any Collateral Account, (ii) instruct the Custodian to liquidate any or all investments held therein and/or (iii) withdraw any amounts held therein and apply such amounts as provided in Section 10.

(b) If immediately available cash on deposit in any Collateral Account is not sufficient to make any distribution or withdrawal to be made pursuant hereto, the Lender will cause to be liquidated, as promptly as practicable, such investments held in or credited to such Collateral Account as shall be required to obtain sufficient cash to make such distribution or withdrawal and, notwithstanding any other provision hereof, such distribution or withdrawal shall not be made until such liquidation has taken place.

SECTION 9. Right to Vote. (a) Unless an Event of Default shall have occurred and is continuing, the Borrower will have the right, from time to time, to vote and to give consents, ratifications and waivers with respect to any Pledged Fund Investment or any other Collateral.

(b) If an Event of Default shall have occurred and is continuing, the Lender will have the right to the extent permitted by law to vote, to give consents, ratifications and waivers and to take any other action with respect to the Pledged Fund Investments, with the same force and effect as if the Lender were the absolute and sole owner thereof, and the Borrower will take all such action as the Lender may reasonably request from time to time to give effect to such right.

SECTION 10. Remedies upon Event of Default. (a) If an Event of Default shall have occurred and is continuing (for the avoidance of doubt, upon commencement by the Lender of any of the remedies set forth herein or in any of the other Credit Documents or upon notice by the Lender to the Borrower or the Manager that it intends to promptly commence the exercise of any such remedies, such Event of Default shall be deemed to be continuing, and may not be cured or curable by any subsequent actions or events), the Lender may exercise (or cause its sub-agents to exercise) any or all of the remedies available to it (or to such sub-agents) under the Credit Documents.

(b) Without limiting the generality of the foregoing, if an Event of Default shall have occurred and is continuing, the Lender may exercise all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised) with respect to any Collateral. In addition, the Lender may, without being required to give any notice, except as herein provided or as may be required by mandatory provisions of law, withdraw all cash held in the Collateral Accounts and apply such cash as provided in Section 11 and, if there shall be no such cash or if such cash shall be insufficient

11

to pay all the Secured Obligations in full, sell, lease, license or otherwise dispose of the Collateral or any part thereof at such place or places as the Lender deems best, and for cash, credit or any combination thereof or for future delivery, at public or private sale, without demand of performance to effect any such disposition or of the time or place thereof, and the Lender or any one else may be the purchaser, lessee, assignee or recipient of any or all of the Collateral so disposed of at any public sale (or, to the extent permitted by law, at any private sale) and thereafter hold the same absolutely, free from any claim or right of whatsoever kind, including any right or equity of redemption (statutory or otherwise) of the Borrower, any such demand, right or equity being hereby expressly waived and released. The Borrower hereby agrees that in the case of any Collateral that is a Bank Loan, the Lender may effect any such disposition by selling such Bank Loan in a private sale in which the Lender is the purchaser followed by a sale by the Lender of participations in such Bank Loan to one or more third parties (who may be affiliates of the Lender), and that such manner of disposition shall be deemed to be commercially reasonable. The Borrower shall remain liable to the Lender for any deficiency following any such sale of Collateral. In addition to the foregoing remedies, the Lender may take any action that is necessary in Lender’s sole good faith discretion to protect, preserve or enforce its rights hereunder or to reduce any risk of loss that it may suffer.

(c) The Lender may adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the sale may be so adjourned. Notice of any such sale or other disposition shall be given to the Borrower to the extent required by Section 13 and by applicable law. If so requested by the Lender or by any buyer of the Collateral or any part thereof, the Borrower shall further ratify and confirm any action taken pursuant to the power of attorney granted herein by executing and delivering to the Lender or to such buyer or buyers at the expense of the Borrower all instruments of assignment, conveyance or transfer, releases, instructions and entitlement orders as may be designated in any such request.

(d) The Lender shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any private sale pursuant to this Section 10 conducted in a commercially reasonable manner. The Borrower hereby waives any claims against the Lender arising by reason of the fact that the price at which the Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Lender accepts the first offer received and does not offer the Collateral to more than one offeree.

12

(e) Without limiting the generality of the foregoing, if an Event of Default shall have occurred and is continuing, the Lender may, pursuant hereto and the Management Agreement, terminate (or cause to be terminated) the Management Agreement and replace (or cause to be replaced) the Manager with an institution selected by the Lender in its sole and absolute discretion (which may be Deutsche Bank AG or any of its Affiliates) legally qualified, permitted under applicable law and with the capacity to assume the responsibilities, duties and obligations of the Manager under the Credit Documents and the Management Agreement.

(f) Notwithstanding anything to the contrary contained herein, none of the rights of the Lender specifically identified herein are intended to limit the rights of the Lender under the Credit Documents.

SECTION 11. Application of Proceeds. If an Event of Default shall have occurred and is continuing, the Lender shall apply (i) any Cash held in the Collateral Accounts and (ii) the Proceeds of any sale or other disposition of all or any part of the Collateral, in the following order of priority:

first, to pay the expenses of such sale or other disposition, including reasonable compensation to agents of and counsel for the Lender, and all expenses, liabilities and advances incurred or made by the Lender in connection with the Credit Documents, and any other amounts then due and payable to the Lender pursuant to Section 12 of this Agreement or Section 8.01 of the Credit Agreement;

second, to pay ratably all interest (including Post-Petition Interest) on the Secured Obligations payable under the Credit Agreement, until payment in full of all such interest and fees shall have been made;

third, to pay the unpaid principal of the Secured Obligations ratably, until payment in full of the principal of all Secured Obligations shall have been made (or so provided for);

fourth, to pay all other Secured Obligations ratably, until payment in full of all such other Secured Obligations shall have been made (or so provided for); and

finally, to pay to the Borrower, or as a court of competent jurisdiction may direct, any surplus then remaining from such Cash or the Proceeds of the Collateral;

The Lender may make such distributions hereunder in cash or in kind or, on a ratable basis, in any combination thereof.

13

SECTION 12. Fees and Expenses; Indemnification. (a) The Borrower will forthwith upon demand pay to the Lender:

(i) the amount of any taxes that the Lender may have been required to pay by reason of the Transaction Liens or to free any Collateral from any other Lien thereon;

(ii) the amount of any and all reasonable out-of-pocket expenses, including transfer taxes and reasonable fees and expenses of counsel and other experts, that the Lender may incur in connection with (x) the administration or enforcement of the Credit Documents, including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection, rank or value of any Transaction Lien, (y) the collection, sale or other disposition of any Collateral or (z) the exercise by the Lender of any of its rights or powers under the Credit Documents;

(iii) the amount of any fees that the Borrower shall have agreed in writing to pay to the Lender and that shall have become due and payable in accordance with such written agreement; and

(iv) the amount required to indemnify the Lender for, or hold it harmless and defend it against, any loss, liability or expense (including the reasonable fees and expenses of its counsel and any experts or sub-agents appointed by it hereunder) incurred or suffered by the Lender in connection with the Credit Documents, except to the extent that such loss, liability or expense directly and primarily arises from the Lender’s gross negligence or willful misconduct or a breach of any duty that the Lender has under this Agreement (after giving effect to Section 14).

Any such amount not paid to the Lender on demand will bear interest for each day thereafter until paid at a rate per annum equal to the Weighted Average Rate in effect from time to time plus the Applicable Margin plus 2%.

(b) If any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in the Collateral Documents, the Borrower will pay such tax and provide any required tax stamps to the Lender or as otherwise required by law.

SECTION 13. Authority to Administer Collateral. The Borrower irrevocably appoints the Lender its true and lawful attorney, with full power of substitution, in the name of the Borrower or otherwise, for the sole use and benefit of the Lender, but at the Borrower’s expense, to the extent permitted by law to exercise, at any time and from time to time following the occurrence and continuance of an Event of Default, all or any of the following powers with respect to all or any of the Collateral:

(a) to demand, sue for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof,

14

(b) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto,

(c) to sell, lease, license or otherwise dispose of the same or the proceeds or avails thereof, as fully and effectually as if the Lender were the absolute owner thereof,

(d) to extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto,

provided that, except in the case of Collateral that threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Lender will give the Borrower prior written notice of the time and place of any public sale thereof or the time after which any private sale or other intended disposition thereof will be made (which the parties agree may be less than ten (10) days prior thereto); provided that, if no notice of such action is required under the UCC, then the Borrower agrees that no such notice shall be required hereunder. Any such notice shall (i) contain the information specified in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required to be notified pursuant to UCC Section 9-611(c); provided that, if the Lender fails to comply with this sentence in any respect, its liability for such failure shall be limited to the liability (if any) imposed on it as a matter of law under the UCC.

SECTION 14. Limitation on Duty in Respect of Collateral. Beyond the exercise of reasonable care in the custody and preservation thereof, the Lender will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent or bailee or any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Lender will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission of any sub-agent or bailee selected by the Lender in good faith, except to the extent that such liability arises directly and primarily from the Lender’s gross negligence or willful misconduct.

15

SECTION 15. Termination of Transaction Liens; Release of Collateral.

(a) The Transaction Liens shall terminate when the Lender has determined that all the Release Conditions have been satisfied.

(b) At any time before the Transaction Liens terminate, the Lender may, at the written request of the Borrower, elect to release any Collateral in its sole and absolute discretion.

(c) Upon any sale of a Fund Investment or any other Collateral in accordance with the terms of the Credit Agreement, the Transaction Lien thereon shall automatically terminate, without any action by the Borrower or the Lender.

(d) Upon any termination of a Transaction Lien or release of Collateral, the Lender will, at the Borrower’s expense, execute and deliver to the Borrower such documents as the Borrower shall reasonably request to evidence the termination of such Transaction Lien or the release of such Collateral, as the case may be.

SECTION 16. Notices. Each notice, request or other communication given to any party hereunder shall be given in accordance with Section 8.03 of the Credit Agreement.

SECTION 17. No Implied Waivers; Remedies Not Exclusive. No failure by the Lender to exercise, and no delay in exercising and no course of dealing with respect to, any right or remedy under any Credit Document shall operate as a waiver thereof; nor shall any single or partial exercise by the Lender of any right or remedy under any Credit Document preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies specified in the Credit Documents are cumulative and are not exclusive of any other rights or remedies provided by law.

SECTION 18. Successors and Assigns. This Agreement is for the benefit of the Lender. If all or any part of Lender’s interest in any Secured Obligation is assigned or otherwise transferred in accordance with Section 8.05 of the Credit Agreement, the transferor’s rights hereunder, to the extent applicable to the obligation so transferred, shall be automatically transferred with such obligation. This Agreement shall be binding on the Borrower and its successors and assigns.

SECTION 19. Amendments and Waivers. Neither this Agreement nor any provision hereof may be waived, amended, modified or terminated except pursuant to an agreement or agreements in writing entered into by the Lender. No such waiver, amendment or modification shall be binding upon the Borrower, except with its written consent.
