(iii) the exercise of the right of first refusal by the Fund pursuant to subclause (ii) above shall be deemed to be the trade date for the purchase of the VMTP Preferred Shares by the Fund from the Purchaser and the sale shall settle within 30 days of such trade date, or if the 30th day of such trade date is not a Business Day, then the next Business Day after such 30th day;

It is the intent and understanding of the Purchaser that the VMTP Preferred Shares constitute stock of the Fund under the laws of the State of Maryland and that all distributions on or with respect to the VMTP Preferred Shares (whether in the form of dividends, redemption payments, liquidation proceeds or otherwise) shall be subject to the restrictions and limitations applicable to distributions on or with respect to corporate stock under the laws of the State of Maryland. All negotiations between the Purchaser (or any of its affiliates) and the Fund regarding the VMTP Preferred Shares have been consistent with such intent and understanding. The Purchaser agrees to treat the VMTP Preferred Shares as equity of the Fund for all U.S. federal, state, and local income and other tax purposes.

SECTION 5.07. Investment Purpose.

The Purchaser is a QIB and is purchasing the VMTP Preferred Shares for its own account for investment purposes only and not with any view toward a resale or distribution thereof.

SECTION 5.08. Underwriter Status.

The Purchaser has no contract, undertaking, agreement or arrangement with any person to sell, transfer or pledge to such person or anyone else any of the VMTP Preferred Shares, and the Purchaser has no present plans to enter into any such contract, undertaking, agreement or arrangement.

ARTICLE VI

COVENANTS OF THE FUND

The Fund agrees that, so long as there is any amount payable hereunder or the Purchaser owns any outstanding VMTP Preferred Shares at any time prior to the registration of VMTP Preferred Shares pursuant to the Registration Rights Agreement:

SECTION 6.01. Future Agreements.

Unless advised in a legal opinion of nationally recognized counsel that entry into such an agreement would violate Applicable Law or the fiduciary duties of the Board of Directors, the Fund shall promptly enter into an agreement, complying with Applicable Law, of the type specified in Section 12(d)(1)(E)(iii) of the 1940 Act as agreed to by the Fund and the tender option bond trust in their commercially reasonable discretion upon any transfer of the VMTP Preferred Shares to a tender option bond trust.

ARTICLE VII

COVENANTS OF THE PURCHASER

SECTION 7.01. Voting Rights.

As of the Closing Date, and for so long as the Purchaser together with any of its affiliates own at least 20% of the Outstanding VMTP Preferred Shares and the Fund has not failed to pay dividends on the VMTP Preferred Shares for two years, the Purchaser shall enter into and maintain in full force and effect a Voting Trust Agreement in substantially the form attached hereto as Exhibit A and thereby convey into the voting trust, governed by the Voting Trust Agreement, the right to vote all of its VMTP Preferred Shares with respect to:

(a) the election of the two members of the Board of Directors for which Holders of VMTP Preferred Shares are exclusively entitled to vote on under Section 18(a)(2)(C) of the 1940 Act and all other rights given to Holders of VMTP Preferred Shares with respect to the election of Board of Directors of the Fund;

(b) the conversion of the Fund from a closed-end management investment company to an open-end fund, or to change the Fund’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 Articles Supplementary that relates solely to any action or amendment to the Articles Supplementary 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 upon which the Conversion is conditioned upon or subject to;

(c) the deviation from a policy in respect of concentration of investments in any particular industry or group of industries as recited in the Fund’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 Articles Supplementary that relates solely to any action or amendment to the Articles Supplementary 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 upon which the Deviation is conditioned upon or subject to; 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 Fund’s registration statement, pursuant to Section 13(a)(2) of the 1940 Act (and of the foregoing, a “Policy Change”), together with any additional voting or consent right under the Articles Supplementary that relates solely to any action or amendment to the Articles Supplementary 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 upon which the Policy Change is conditioned upon or subject to;

Each voting right set forth in clauses (a) through (d) above a “Voting Right.”

At all times Voting Rights are subject to the Voting Trust Agreement, the Purchaser or its affiliate will be the registered owner of the VMTP Preferred Shares. If any dividend or other distribution in respect of the Subject Shares is paid, such dividend or distribution will be paid directly to the Purchaser; provided, that, any Additional Shares will become part of the Subject Shares covered by the Voting Trust Agreement.

The Voting Rights shall remain subject to the Voting Trust Agreement for so long as the Purchaser and its Affiliates are the Beneficial Owners in the aggregate of 20% or more of the Outstanding VMTP Preferred Shares.

At all times the Voting Rights are subject to the Voting Trust Agreement, the Purchaser shall irrevocably appoint and constitute, and shall cause each of its Affiliates who are Beneficial Owners of any Subject Shares to irrevocably appoint and constitute, the Director as its attorney-in-fact and agrees, and agrees to cause each of such Affiliates, to grant the Director one or more irrevocable proxies with respect to the Voting Rights and further agrees to renew any such proxies that may lapse by their terms while the Subject Shares are still subject to the Voting Trust Agreement.

Notwithstanding the above provisions of this Section 7.01, upon the transfer of VMTP Preferred Shares by the Purchaser to any third party (other than a transfer to an affiliate of the Purchaser in which case such Preferred Shares shall remain subject to the Voting Trust Agreement) such VMTP Preferred Shares shall no longer be subject to the Voting Trust Agreement; provided, however, in connection with an Excluded Transfer:

(i) of the type specified in clause (1) of the definition of Excluded Transfer, the VMTP Preferred Shares shall remain subject to the Voting Trust Agreement until such time as the Fund enters into a voting arrangement of the type specified in Section 12(d)(1)(E)(iii) of the 1940 Act;

(ii) of the type specified in clauses (2) or (3) of the definition of Excluded Transfer, to the extent the Purchaser retains the right to vote or direct voting in connection with such transactions, the VMTP Preferred Shares shall be subject to the Voting Trust Agreement until such time as there is a default by the Purchaser under such repurchase transaction or collateral pledge arrangement; and

(iii) as specified in clauses (2) or (3) of the definition of Excluded Transfer, to the extent the Purchaser does not retain the right to vote or direct voting of such VMTP Preferred Shares in such transactions, such transactions do not permit the removal of the VMTP Preferred Shares’ rights transferred to the Voting Trust from the Voting Trust Agreement within the first 60 days of closing of such transferee becoming the Beneficial Owner of such VMTP Preferred Shares unless there is a default by the Purchaser under such repurchase transaction or collateral pledge arrangement.

Without the prior written consent of the Fund (in its sole discretion), the Purchaser will not agree or consent to any amendment, supplement, modification or repeal of the Voting Trust Agreement, nor waive any provision thereof; provided, that in the case of any proposed amendment, supplement, modification or repeal of the Voting Trust Agreement which is a result of a change in law or regulation, the consent of the Fund shall not be unreasonably withheld or delayed.

SECTION 7.02. Tax Treatment.

The Purchaser agrees to treat the Preferred Shares as equity of the Fund for all U.S. federal, state, and local income and other tax purposes.

SECTION 8.02. No Waivers.

(a) The obligations of the Fund hereunder shall not in any way be modified or limited by reference to any other document, instrument or agreement (including, without limitation, any other Related Document) other than the Articles Supplementary and the VMTP Preferred Shares. The rights of the Purchaser hereunder are separate from and in addition to any rights that any Holder or Beneficial Owner of any VMTP Preferred Shares may have under the terms of such VMTP Preferred Shares or any Related Document or otherwise. In the event of an irreconcilable conflict between the terms hereof and the terms of the Articles Supplementary or the VMTP Preferred Shares, the terms of the Articles Supplementary shall govern.

(b) No failure or delay by the Fund or the Purchaser in exercising any right, power or privilege hereunder or under any other Related documents or the VMTP Preferred Shares shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No failure or delay by the Fund or the Purchaser in exercising any right, power or privilege under or in respect of the VMTP Preferred Shares or any other Related Document shall affect the rights, powers or privileges of the Fund or the Purchaser hereunder or thereunder or shall operate as a limitation or waiver thereof. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

SECTION 8.03. Expenses and Indemnification.

(a) [Reserved].

(b) Except as otherwise provided herein, the Fund agrees to indemnify and hold harmless the Purchaser and each other Indemnified Person of the Purchaser from and against any losses, claims, damages, liabilities or expenses incurred by them (including reasonable fees and disbursements of outside counsel) (“Expenses”), in connection with the defense of any lawsuit, action, claim, threat or demand by any Common Shareholders or their representatives in connection with the Purchaser’s execution and performance of this Agreement.

Notwithstanding anything herein to the contrary, the Fund shall not be liable for, and no Indemnified Person shall be entitled to indemnification or contribution under this Section 8.03 for, (1) any Expenses arising by reason of such Indemnified Person’s (i) willful misfeasance, (ii) bad faith or (iii) gross negligence, (2) any consequential, punitive, special or speculative losses, damages or expenses incurred or suffered by any Indemnified Person as a result of the transactions contemplated by this Agreement, including any opportunity cost of capital, such as the loss of anticipated or disgorgement of previously received dividends, interest, capital gains or any other profit or gain from any investment opportunity or activity foregone by such Indemnified Person as a result of the transactions contemplated by this Agreement or (3) any alleged loss incurred as a result of the Fund’s failure to pay any amount on or with respect to the VMTP Preferred Shares (whether dividends, redemption payments, liquidation proceeds or otherwise) due to the lack of funds legally available therefor or because of any other Applicable Law restrictions on such payments.

(c) The Fund also agrees that if any indemnification sought by an Indemnified Person pursuant to this Agreement is unavailable or insufficient, for any reason, to hold harmless the Indemnified Persons of the other party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), then the Fund, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Expenses in such proportion as is appropriate to reflect (i) the relative benefits received by the Fund on the one hand and the Purchaser on the other hand from the actual or proposed transactions giving rise to or contemplated by this Agreement or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the Fund on the one hand and the Purchaser on the other, giving rise to such Expenses, as well as any other relevant equitable considerations; provided that in any event the aggregate contribution of the Purchaser and its Indemnified Persons to all Expenses with respect to which contributions are available hereunder will not exceed the amount of dividends actually received by the Purchaser from the Fund pursuant to the proposed transactions giving rise to this Agreement. For purposes of determining the relative benefits to the Fund on the one hand, and the Purchaser on the other, under the proposed transactions giving rise to or contemplated by this Agreement, such benefits shall be deemed to be in the same proportion as (i) the total proceeds received or proposed to be received by the Fund pursuant to the transactions, whether or not consummated, for which the Purchaser is purchasing VMTP Preferred Shares bears to (ii) the dividends paid by the Fund or on the Fund’s behalf to the Purchaser in connection with the proposed transactions giving rise to or contemplated by this Agreement. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for such fraudulent misrepresentation. The indemnity, reimbursement and contribution obligations under this Agreement shall be in addition to any rights that any Indemnified Person may have at common law or otherwise.

(d) If an Indemnified Person is named as a defendant in any action, suit, proceeding or investigation as to which the Indemnified Person proposes to demand indemnification hereunder, it shall notify the Fund with reasonable promptness; provided, however, that any failure by such Indemnified Person to notify the Fund shall not relieve the Fund from its obligations hereunder (except to the extent that the Fund is materially prejudiced by such failure to promptly notify). The Fund shall be entitled to assume the defense of any such action, suit, proceeding or investigation, including the employment of counsel reasonably satisfactory to the Indemnified Person. The Indemnified Person shall have the right to counsel of its own choice to represent it, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Fund has failed promptly to assume the defense and employ counsel reasonably satisfactory to the Indemnified Person in accordance with the preceding sentence or (ii) the Indemnified Person shall have been advised by counsel that there exist actual or potential conflicting interests between the Fund and such Indemnified Person, including situations in which one or more legal defenses may be available to such Indemnified Person that are different from or additional to those available to the Fund; provided, however, that the Fund shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations be liable for fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Persons of the other party; and such counsel shall, to the extent consistent with its professional responsibilities, cooperate with the Fund and any counsel designated by the Fund.

Each party further agrees that it will not, without the prior written consent of the other party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not any Indemnified Person is an actual or potential party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of each other Indemnified Person from all liability and obligations arising therefrom. The Fund further agrees that neither the Purchaser, nor any of its affiliates, nor any directors, officers, partners, employees, agents, representatives or control persons of the Purchaser or any of its affiliates shall have any liability to the Fund arising out of or in connection with the proposed transactions giving rise to or contemplated by this Agreement. No party shall be responsible or liable to the other party or any other person for consequential, special or punitive damages which may be alleged as a result of this Agreement.

(e) Nothing in this Section is intended to limit any party’s obligations contained in other parts of this Agreement or the VMTP Preferred Shares.

SECTION 8.04. Amendments and Waivers.

Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Fund and the Purchaser.

SECTION 8.05. Successors and Assigns.

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Neither party hereto may assign or otherwise transfer any of its rights under this Agreement, by operation of law or otherwise, without the prior written consent of the other party. Any assignment without such prior written consent shall be void.

SECTION 8.06. Term of this Agreement.

This Agreement shall terminate on the earlier of (i) the date upon which the Purchaser is the Beneficial Owner of no VMTP Preferred Shares, provided that the Purchaser shall be deemed to be the Beneficial Owner of any VMTP Preferred Shares transferred in connection with clauses (1), (2) or (3) of the definition of Excluded Transfer, (ii) the registration of any Outstanding VMTP Preferred Shares under the Securities Act and (iii) payment in full of all amounts owing to the Purchaser hereunder and under the VMTP Preferred Shares; and notwithstanding any termination of this Agreement, the notice requirement of Section 7.01, Section 8.03, Section 8.07, Section 8.08, Section 8.10, Section 8.11 and Section 8.13 (for a period of one year after the termination of this Agreement) shall remain in full force and effect.

SECTION 8.07. Governing Law.

This Agreement shall be construed in accordance with and governed by the domestic law of the State of New York.

THE PARTIES HERETO HEREBY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF THE FEDERAL AND NEW YORK STATE COURTS LOCATED IN THE CITY OF NEW YORK IN CONNECTION WITH ANY DISPUTE RELATED TO THIS AGREEMENT OR ANY MATTERS CONTEMPLATED HEREBY.

SECTION 8.08. Waiver.

The Fund and the Purchaser hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected with this Agreement.

SECTION 8.09. Counterparts.

This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Any counterpart or other signature delivered by facsimile or by electronic mail shall be deemed for all purposes as being a good and valid execution and delivery of this Agreement by that party.

The exchange of copies of this Agreement and of signature pages that are executed by manual signatures that are scanned, photocopied or faxed or by other electronic signing created on an electronic platform (such as DocuSign) or by digital signing (such as Adobe Sign) that is approved by the parties hereto, shall constitute effective execution and delivery of this Agreement for all purposes. Signatures of the parties hereto that are executed by manual signatures that are scanned, photocopied or faxed or by other electronic signing created on an electronic platform (such as DocuSign) or by digital signing (such as Adobe Sign) that is approved by the parties hereto shall be deemed to be their original signatures for all purposes of this Amendment as to the parties hereto and may be used in lieu of the original.

Anything in this Agreement to the contrary notwithstanding, for the purposes of the transactions contemplated by this Agreement and any document to be signed in connection with this Agreement (including amendments, supplements, waivers, consents and other modifications and issuance and delivery documents) or the transactions contemplated hereby may be signed by manual signatures that are scanned, photocopied or faxed or other electronic signatures created on an electronic platform (such as DocuSign) or by digital signature (such as Adobe Sign) that is approved by the parties hereto, and contract formations on electronic platforms approved by the parties hereto, and the keeping of records in electronic form, are hereby authorized, and each shall be of the same legal effect, validity or enforceability as a manually executed signature in ink or the use of a paper-based recordkeeping system, as the case may be.

SECTION 8.10. Beneficiaries.

This Agreement is not intended and shall not be construed to confer upon any Person other than the parties hereto and their successors and permitted assigns any rights or remedies hereunder.

SECTION 8.11. Entire Agreement.

This Agreement shall constitute the entire agreement and understanding between the parties hereto with respect to the matters set forth herein and shall supersede any and all prior agreements and understandings relating to the subject matter hereof.

SECTION 8.12. Severability.

In case any provision of this Agreement shall be invalid, illegal, or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby so long as the intent of the Parties to this Agreement shall be preserved.

SECTION 8.13. Confidentiality.

All information, whether oral, written, via computer disk or electronic media or otherwise, to which a party is given access or which is made available to it by the other party (including by such other party’s agents and representatives) in connection with the transactions contemplated by this Agreement or any other Related Document is referred to as “Confidential Information”. Confidential Information shall include, without limitation, all technology, processes, trade secrets, contracts, proprietary information, portfolio information, historical and projected financial information, operating data and organizational cost structures, strategic or management plans, customer information and customer lists, whether received before or after the date hereof. Confidential Information shall also include information of or relating to any parent, subsidiary or affiliate of a party.

Each party agrees to hold all Confidential Information in confidence, that it will not disclose any Confidential Information to any Person, other than directors, officers, employees, agents or representatives (including those of a legal nature) or prospective purchasers of VMTP Preferred Shares or interests therein that have agreed to keep such information confidential (collectively, the “Representatives”) who have a need to know such information in connection with the transactions contemplated by this Agreement or any other Related Document (the “Transactions”), and that it will not use any such Confidential Information for purposes other than in connection with the Transactions. Notwithstanding the restrictions listed in the preceding sentence, copies of the Related Documents and the Information Statement prepared in connection with the issuance of the VMTP Preferred Shares (or any updated, amended, or additional information statement subsequently prepared in connection with the VMTP Preferred Shares) may be distributed to prospective investors in tender option bond trusts into which the VMTP Preferred Shares have or may be deposited for the purpose of such investor’s evaluation of an investment in such tender option bond trust. For the avoidance of doubt, any Rating Agency rating the VMTP Preferred Shares at the request of the Fund shall not be deemed to be a Representative for purposes of this Section 8.13 and will not be subject to the obligations of this Section 8.13. Each party agrees to inform its Representatives of the confidential and valuable nature of the Confidential Information and of its obligations under this Section 8.13. Each party shall be responsible and liable for any breach of this Section 8.13 by its Representatives. Each party agrees to use reasonable care and implement reasonable controls, but in all events at least the same degree of care and controls that it uses to protect its own confidential and proprietary information of similar importance, to prevent the unauthorized use, disclosure or availability of Confidential Information.

It is understood and agreed that no information shall be within the protection of this Section 8.13 where such information: (a) is or becomes publicly available through no fault of either party or its Representatives, (b) is authorized to be released by the disclosing party, (c) is rightly obtained from a third party, who, to the receiving party’s knowledge, is not under obligation of confidentiality, (d) is required to be disclosed as a matter of law, regulation or industry best practice or legal process or (e) is made available to any regulatory body.

In the event that either party to this Agreement or any of its Representatives become legally compelled (by deposition, interrogatory, request for documents, subpoena, regulatory request or demand, civil investigative demand or similar process (“Legal Process”)) to disclose any of the Confidential Information, such party may disclose such Confidential Information to the extent legally required; provided, however, that the Purchaser shall, to the extent permitted by law, rule and regulation and reasonably practicable, notify the Fund prior to such disclosure by the Purchaser so that the Fund may seek, at the Fund’s expense, a protective order or other appropriate remedy; provided, further, that the Purchaser will have no liability to the Fund for failure to provide such notice. In the absence of such protective order, other remedy or waiver by the Fund, the Purchaser may disclose such Confidential Information to the extent legally required. Notwithstanding anything to the contrary contained herein, either party and its affiliates may disclose Confidential Information, without notice to the other party, to any governmental agency, regulatory authority or self-regulatory authority (including, without limitation, bank and securities examiners) having or claiming to have authority to regulate or oversee any aspect of the party’s business or that of its affiliates in connection with the exercise of such authority or claimed authority. Nothing herein shall require a party to fail to honor any Legal Process on a timely basis.

In the event that this Agreement is terminated, or at any time upon request, each party agrees to return promptly or destroy all copies of the Confidential Information without retaining any copies thereof and to destroy all copies of any analyses, compilations, studies or other documents prepared by it or for its use containing or reflecting any Confidential Information. Provided however each party will be permitted to retain all or any portion or the Confidential Information to comply with its governing laws, regulations or internal policies. Such Confidential Information shall remain subject to the confidentiality obligations set forth in this Section 8.13.

Inasmuch as any breach of this Section 8.13 may result in immediate and irreparable injury, it is recognized and agreed that each party shall be entitled to equitable relief, including injunctive relief and specific performance, in addition to all other remedies available at law. Further, all obligations, rights and remedies hereunder shall survive any return or destruction of the Confidential Information and any termination of this Agreement; provided, however, that all obligations, rights and remedies hereunder shall survive the termination of this Agreement and remain in full force and effect for one (1) year after the termination of this Agreement.

It is further understood and agreed that no failure or delay by either party in exercising any right, power or privilege under this Section 8.13 shall operate as a waiver hereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege under this Section 8.13.

Notwithstanding any other provision of this Agreement, any party or Representative may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Fund and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment or tax structure; provided that the foregoing does not constitute an authorization to disclose information identifying the Fund or any parties to transactions engaged in by the Fund (except to the extent relating to such tax structure or tax treatment) any non-public commercial or financial information.

SECTION 8.14. General.

Notwithstanding anything expressed or implied in this Agreement to the contrary, nothing in this Agreement shall confer upon the Purchaser any rights to dividends on, or a redemption of, VMTP Preferred Shares (other than the rights provided to Holders under the Articles Supplementary) or any rights which would result in the VMTP Preferred Shares owned or held by the Purchaser having priority over VMTP Preferred Shares owned or held by any other person as to distribution of assets or payment of dividends.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
