("BANA") and the Issuer (the "Fee Agreement");

WHEREAS, the Purchaser desires to transfer and assign irrevocably to the Trustee, and the Trustee desires to accept such transfer and assignment of, the right to vote and consent for the Purchaser in connection with all of its voting and consent rights and responsibilities, as set forth in Section 1 below, as a Beneficial Owner of (i) VRDP Shares acquired by the Purchaser pursuant to the Fee Agreement (such VRDP Shares, when owned by the Purchaser, the "Subject Shares") and (ii) any additional shares of VRDP Shares or preferred shares of any class or series of the Issuer having voting powers of which an Affiliate of PFC is the Beneficial Owner or that the Purchaser becomes the Beneficial Owner of during the term of this Agreement (any such additional preferred shares of the Issuer having voting powers being "Additional Shares" and when so acquired will become a part of the "Subject Shares" covered by this Agreement);

WHEREAS, the Voting Consultant shall analyze any matters requiring the owner of Subject Shares, to vote or consent in its capacity as an equity holder (whether at a meeting or via a consent solicitation), and shall provide a recommendation to the Trustee of how to vote or consent with respect to such voting or consent matters;

WHEREAS, the Voting Consultant and the Trustee are Independent of the Purchaser; and

WHEREAS, the parties hereto desire to set forth in writing their understandings and agreements.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises hereinafter set forth and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending legally and equitably to be bound, hereby agree as follows:

1. Creation of Trust

The Purchaser hereby irrevocably transfers and assigns to the Trustee, and the Trustee hereby accepts the transfer and assignment of, the right to vote and consent for the Purchaser in connection with all of its voting and consent rights and responsibilities as Beneficial Owner of the Subject Shares with respect to the following matters (collectively, the "Voting Matters"):

(a) the election of the two members of the Board for which Holders of VRDP Shares are exclusively entitled to vote under Section 18(a)(2)(C) of the Investment Company Act of 1940, as amended (the "1940 Act") and all other rights given to Holders of VRDP Shares with respect to the election of the Board of the Issuer;

(b) the conversion of the Issuer from a closed-end management company to an open-end management company, or to change the Issuer's classification from diversified to non-diversified, each pursuant to Section 13(a)(1) of the 1940 Act (any of the foregoing, a "Conversion"), together with any additional voting or consent right under the Statement of Preferences and the Fee Agreement that relates solely to any action or amendment to the Statement of Preferences that is so closely related to the Conversion that it would be impossible to give effect to the Conversion without implicating such additional voting or consent right; provided that any such additional voting or consent right shall not include any voting or consent right related to satisfying any additional term, condition or agreement which the Conversion is conditioned upon or subject to or, for the avoidance of doubt, any voting or consent right relating to any amendment or waiver of Section 6, 7 or 10 of the Statement of Preferences or any definitions relevant to such Section;

(c) the deviation from a policy in respect of concentration of investments in any particular industry or group of industries as recited in the Issuer's registration statement, pursuant to Section 13(a)(3) of the 1940 Act (a "Deviation"), together with any additional voting or consent right under the Statement of Preferences and the Fee Agreement that relates solely to any action or amendment to the Statement of Preferences that is so closely related to the Deviation that it would be impossible to give effect to the Deviation without implicating such additional voting or consent right; provided that any such additional voting or consent right shall not include any voting or consent right related to satisfying any additional term, condition or agreement which the Deviation is conditioned upon or subject to or, for the avoidance of doubt, any voting or consent right relating to any amendment or waiver of Section 6, 7 or 10 of the Statement of Preferences or any definitions relevant to such Section; and

(d) borrowing money, issuing senior securities, underwriting securities issued by other Persons, purchasing or selling real estate or commodities or making loans to other Persons other than in accordance with the recitals of policy with respect thereto in the Issuer's registration statement, pursuant to Section 13(a)(2) of the 1940 Act (any of the foregoing, a "Policy Change"), together with any additional voting or consent right under the Statement of Preferences and the Fee Agreement that relates solely to any action or amendment to the Statement of Preferences that is so closely related to the Policy Change that it would be impossible to give effect to the Policy Change without implicating such additional voting or consent right; provided that any such additional voting or consent right shall not include any voting or consent right related to satisfying any additional term, condition or agreement which the Policy Change is conditioned upon or subject to or, for the avoidance of doubt, any voting or consent right relating to any amendment or waiver of Section 6, 7 or 10 of the Statement of Preferences or any definitions relevant to such Section.

In order to effect the transfer of voting and consent rights with respect to the Voting Matters, PFC hereby irrevocably appoints and constitutes, and will cause each of its Affiliates who are Beneficial Owners of any Subject Shares to irrevocably appoint and constitute, the Trustee as its attorney-in-fact and agrees, and agrees to cause each of such Affiliates, to grant the Trustee one or more irrevocable proxies with respect to the Voting Matters and further agrees to renew any such proxies that may lapse by their terms while the Subject Shares are still subject to this Agreement.

PFC will retain all other voting rights under the Related Documents and PFC, its Affiliates or designee will also be the registered owner of the VRDP Shares. If any dividend or other distribution in respect of the Subject Shares is paid, such dividend or distribution will be paid directly to PFC or its Affiliate or designee owning such Subject Shares; provided, that, any Additional Shares will become part of the Subject Shares covered by this Agreement.

(b) of the type specified in clauses (3) or (4) of the definition of Excluded Transfer, to the extent BANA or any of its Affiliates retains the right to vote or direct voting in connection with such transactions, the Subject Shares shall remain subject to this Agreement until such time as there is a default by BANA or such Affiliate under such repurchase transaction or collateral pledge arrangement; and

(c) of the type specified in clauses (3) or (4) of the definition of Excluded Transfer, to the extent BANA or any of its Affiliates does not retain the right to vote or direct voting of such Subject Shares in such transactions, such transactions do not permit the removal of the Subject Shares' rights transferred to the Voting Trust pursuant to this Agreement within the first 60 days of closing of such transferee becoming the Beneficial Owner of such Subject Shares unless there is a default by BANA or such Affiliate under such repurchase transaction or collateral pledge arrangement.

4. Trustee

(a) Rights And Powers Of Trustee. With respect to Subject Shares where the Purchaser is the Beneficial Owner, the Trustee shall, in person or by nominees, agents, attorneys-in-fact, or proxies, have the right and the obligation to exercise its discretion with respect to all Voting Matters requiring Holders of VRDP Shares to vote or consent with respect to and including voting or consenting to any corporate or shareholder action of any kind whatsoever, subject to the terms of this Agreement. The Trustee shall be obligated to vote any Voting Matter in accordance with the provisions of this Agreement.

(b) Liability Of Trustee. In exercising the rights and powers of the Trustee, the Trustee will exercise any rights and powers in the Trustee's best judgment; provided, however, the Trustee shall not be liable for any action taken by such Trustee or the Trustee's agent, except for liability arising from the Trustee's bad faith, wilful misconduct or gross negligence. The Trustee shall not be required to give any bond or other security for the discharge of the Trustee's duties.

(c) Resignation of and Successor Trustee. The Trustee may at any time resign the Trustee's position as Trustee by delivering a resignation in writing to the Purchaser and the Voting Consultant to become effective 90 days after the date of such delivery, but in any event such notice shall not become effective prior to the acceptance of a successor Trustee. The Trustee shall nominate a successor Trustee acceptable to the Purchaser, who shall have all rights, powers and obligations of the resigning Trustee as set forth in this Agreement, and all rights, powers and obligations of the resigning Trustee hereunder shall immediately terminate upon the acceptance by the successor Trustee of such nomination and the execution of this Agreement by the successor Trustee as "Trustee" hereunder. No such resignation shall become effective until such time as a successor Trustee has been appointed and such appointment has been accepted. The fact that any Trustee has resigned such Trustee's position as a Trustee shall not act, or be construed to act, as a release of any Subject Shares from the terms and provisions of this Agreement.

(d) Removal. The Trustee may be removed by the Purchaser upon 30 days prior written notice upon either (i) a material breach by the Trustee of its obligations hereunder or (ii) any action or inaction of the Trustee which constitutes bad faith, negligence or wilful misconduct in the performance of its obligations hereunder.

(e) Independent. The Trustee represents that it is Independent of PFC.

5. Voting Consultant

(a) Liability Of Voting Consultant. In providing its voting recommendations on Voting Matters hereunder, the Voting Consultant will provide such recommendations in the Voting Consultant's best judgment with respect to the Voting Matters for the VRDP Shares; provided, however, the Voting Consultant shall not be liable for any action taken by such Voting Consultant or the Voting Consultant's agent, except for liability arising from the Voting Consultant's bad faith, wilful misconduct or gross negligence. For the avoidance of doubt, the Voting Consultant's maximum liability shall be limited to an amount not to exceed the total amounts of the fees the Voting Consultant receives from the Purchaser under the Master Agreement (as defined in Section 5(d)) in any one year period for any and all claims made within that one year period; provided that if a breach of Section 5(e) is determined to have occurred, the sole remedy shall be the immediate removal of the Voting Consultant by the Purchaser in the Purchaser's sole discretion and no monetary damages shall be due or payable. In addition, the Voting Consultant shall not be liable for any action taken by the Trustee contrary to the recommendations provided by the Voting Consultant.

(b) Resignation of and Successor Voting Consultant. The Voting Consultant may at any time resign the Voting Consultant's position as Voting Consultant by delivering a resignation in writing to the Purchaser and to the Trustee to become effective 90 days after the date of such delivery. Upon receipt of the Voting Consultant's written resignation, the Purchaser shall use commercially reasonable efforts to appoint a successor Voting Consultant which has been consented to by the Trustee, such consent not to be unreasonably withheld. If the Voting Consultant shall resign but a successor Voting Consultant has not assumed all of the Voting Consultant's duties and obligations within 90 days of such resignation, the Voting Consultant may petition any court of competent jurisdiction for the appointment of a successor Voting Consultant. No such resignation shall become effective until such time as a successor Voting Consultant has been appointed and such appointment has been accepted.

(c) Removal. The Voting Consultant may be removed by the Purchaser upon 30 days prior written notice upon either (i) a material breach by the Voting Consultant of its obligations hereunder or (ii) any action or inaction of the Voting Consultant which constitutes bad faith, gross negligence or wilful misconduct in the performance of its obligations hereunder.

(d) Contract. A separate contract, that certain Master Services Agreement No. (24828001-001) by and between the Voting Consultant and the Purchaser, as may be amended from time to time with the prior written consent of the parties thereto (the "Master Agreement"), sets forth additional details, including fees, pursuant to which the Voting Consultant is providing the services contemplated hereunder.

(e) Independent. The Voting Consultant represents that it is Independent of PFC; provided, however, if the Voting Consultant becomes aware that the Voting Consultant is no longer Independent of the Purchaser, the Voting Consultant shall promptly, and in no event later than two Business Days after becoming aware, notify the Purchaser and shall abstain from making voting recommendations during any period of time during which the Voting Consultant is not Independent of the Purchaser. If the Voting Consultant notifies the Purchaser that it is no longer Independent of the Purchaser, the Purchaser shall use commercially reasonable efforts to identify and appoint a replacement voting consultant.

6. Amount of Subject Shares Notification

On any and each date that the Purchaser sells or otherwise transfers any Subject Shares to another Beneficial Owner, the Purchaser shall promptly notify the Trustee of such occurrence and the number of VRDP Shares that the Purchaser then owns.

7. Voting Communications

The Purchaser shall notify the Trustee and the Voting Consultant as soon as possible, and in any event, not later than five Business Days after receipt of notice that a vote of the holders of VRDP Shares has been requested or permitted on any Voting Matter and the Purchaser shall, within such same time frame, forward any information sent to the Purchaser in connection with such vote to the Trustee and the Voting Consultant by Electronic Means.

The Voting Consultant shall analyze and provide a voting or consent recommendation to the Trustee with respect to each Voting Matter in respect of the Subject Shares. The Trustee is obligated to act in accordance with the voting or consent recommendation made by the Voting Consultant in its voting or consent direction to the Purchaser. In all Voting Matters, the Trustee shall use the proxies granted to it by the Purchaser to vote or consent the Subject Shares in accordance with the voting or consent recommendation made by the Voting Consultant and the Purchaser shall not exercise any voting or consent rights in such matters.

If the Voting Consultant fails to provide a voting or consent recommendation to the Trustee on or prior to the deadline for submission of such vote or consent, the Trustee shall not provide a vote or consent on behalf of the Purchaser on such deadline and shall provide notice of the failure to receive a voting or consent recommendation to the Purchaser and the Voting Consultant. For the avoidance of doubt, the Purchaser shall not retain the right to vote or consent on any Voting Matters for which the Trustee does not provide a vote or consent on behalf of the Purchaser.

8. Indemnification

The Purchaser shall indemnify and hold the Trustee and the Voting Consultant and such Trustee's and such Voting Consultant's agents harmless from and against any and all liabilities, obligations, losses, damages, penalties, taxes, claims, actions, suits, reasonable costs, reasonable expenses or disbursements (including reasonable legal fees and expenses) of any kind and nature whatsoever in connection with or growing out of (i) with respect to the Trustee, the administration of the voting trust created by this Agreement or (ii) with respect to the Trustee and the Voting Consultant, the exercise of any powers or the performance of any duties by the Trustee or the Voting Consultant as herein provided or contemplated, including, without limitation, any action taken or omitted to be taken, except, with respect to the Trustee and the Voting Consultant separately, such as may arise from the bad faith, willful misconduct or gross negligence of the Trustee or the Voting Consultant, respectively.
