All payments of any sums due hereunder shall be made in the amounts required hereunder without any reduction or setoff, notwithstanding the availability of any right of recoupment or setoff or of any counterclaim by the Fund, each of which is hereby waived.

6.6 Compliance With Law

All information, reports and other papers, documentation and data with respect to the Fund furnished to the Purchaser pursuant to this Section 6.9 shall be, at the time the same are so furnished, complete and correct in all material respects and, when considered with all other material delivered to the Purchaser under this Agreement or made available pursuant to the Due Diligence Request, will not contain untrue statements of material facts or omit to state material facts necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading.

6.12 [Reserved]

6.13 Other Portfolio Investment Covenants

If and for so long as the Fund fails to provide the information required under Sections 6.1(o) and 6.1(p), the Purchaser may, in its sole discretion, calculate, for purposes of Section 2.2(c) of the Variable Rate Mode Supplement, the Effective Leverage Ratio using the most recently received information required to be delivered pursuant to Sections 6.1(o) and 6.1(p) and the Market Values of portfolio investments determined by reference to current market prices at the time of calculation and any information made publicly available by the Fund relevant to the calculation of the Effective Leverage Ratio. The Effective Leverage Ratio as and if so calculated by the Purchaser in such instances shall be binding on the Fund. If required based on such calculations, the Fund shall restore the Effective Leverage Ratio as provided in Section 2.3(c)(ii) of the Variable Rate Mode Supplement.

In connection with calculating the Effective Leverage Ratio, the Fund’s total assets and accrued liabilities shall reflect the positive or negative net obligations of the Fund under each Derivative Contract determined in accordance with the Fund’s valuation policies.

Except as provided below, unless the Fund receives the prior written consent of the Purchaser, the Fund shall not (x) deposit assets of the Fund into a new tender option bond trust or deposit additional assets of the Fund into an existing tender option bond trust, in each case providing for the issuance of floating rate trust certificates and regardless of (i) whether the sponsor/trustor for the tender option bond trust is the Fund or any affiliate thereof or any unaffiliated entity, (ii) the identity of the holder of the associated residual floating rate trust certificates issued by any such tender option bond trust or (iii) whether such deposit is effected indirectly through the use of a custodial arrangement pursuant to which the Fund’s assets are represented by custodial receipts deposited into such tender option bond trust or (y) acquire residual floating rate trust certificates issued by any tender option bond trust (each of clauses (x) and (y), a “TOB Increase Event”), if, after giving effect to any such deposit and the issuance of the floating rate trust certificates and associated residual floating rate trust certificates by such tender option bond trust or any such acquisition of residual floating rate trust certificates, the Effective Leverage Ratio of the Fund would exceed 35% as of the date of issuance of such trust certificates or the date of acquisition of such residual floating rate trust certificates, provided that, the Fund may consummate a TOB Increase Event without the prior written consent of the Purchaser notwithstanding that after giving effect to the deposit of assets and the issuance of floating rate trust certificates and associated residual floating rate trust certificates or the acquisition of residual floating rate trust certificates, in each case, in connection with such TOB Increase Event, the Effective Leverage Ratio of the Fund would exceed 35% (so long as it would not exceed 37% ), if, as of the close of business on the third Business Day after the trade date for the TOB Increase Event, the numerator of the Effective Leverage Ratio of the Fund is equal to or less than the numerator of the Effective Leverage Ratio of the Fund as of the close of business on the Business Day immediately preceding the trade date for the TOB Increase Event. For the avoidance of doubt, the numerator of the Effective Leverage Ratio is paragraph (i) of the definition of Effective Leverage Ratio.

The Fund agrees that, notwithstanding anything to the contrary in the definition of Liquidity Account Investments, to the extent that any securities or investments rated below BBB- or the equivalent rating are to be considered Liquidity Account Investments, the Fund shall have first allocated as Liquidity Account Investments all securities and investments rated at or above BBB- or the equivalent rating.

6.14 Tender and Paying Agent

The Fund shall use its commercially reasonable best efforts to engage at all times a Tender and Paying Agent to perform the duties to be performed by the Tender and Paying Agent specified herein and in the Variable Rate Mode Supplement.

6.15 Cooperation in the Sale of the MFP Shares

The Fund will comply with reasonable due diligence requests from the Purchaser in connection with any proposed sale by the Purchaser of the MFP Shares in a transaction exempt from registration under the Securities Act and otherwise permitted by this Agreement, provided that (i) the Fund need not comply with any such request more than twice in any period of twelve consecutive months, and (ii) any prospective purchaser of the MFP Shares from the Purchaser (including an affiliate of the Purchaser) shall execute a confidentiality agreement substantially to the effect of Section 7.13 hereof prior to receiving any due diligence materials provided pursuant to such due diligence request.

All information, reports and other papers, documentation and data with respect to the Fund furnished to the Purchaser pursuant to this Section 6.15 shall be, at the time the same are so furnished, complete and correct in all material respects and, when considered with all other material delivered to the Purchaser under this Agreement or made available pursuant to the Due Diligence Request, will not contain untrue statements of material facts or omit to state material facts necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading.

6.16 Use of Proceeds

The Fund shall use the net proceeds from the sale of the Additional MFP Shares for the purposes set forth in the Pricing Supplement.

6.17 Securities Depository

The Fund agrees to use its best efforts to maintain settlement of the MFP Shares in global book entry form through the Securities Depository or such other clearance system acceptable to the Purchaser.

6.18 Future Agreements

The Fund shall promptly, at the request of the Purchaser, enter into an agreement, on terms mutually satisfactory to the Fund and the Purchaser, of the type specified in Section 12(d)(1)(E)(iii) of the 1940 Act, so as to permit the Purchaser or any transferee satisfying the requirements set forth in Section 2.1 to rely on the provisions of Section 12(d)(1)(E)(iii) of the 1940 Act.

(b)

No failure or delay by the Fund or the Purchaser in exercising any right, power or privilege hereunder or under the MFP 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.

7.3 Expenses and Indemnification

	(a)	The Fund shall upon demand either, as the Purchaser may require, pay in the first instance or reimburse the Purchaser (to the extent that payments for the following items are not made under the other provisions hereof) for all reasonable documented out-of-pocket expenses (including reasonable documented fees and costs of outside counsel, and reasonable documented consulting, accounting, appraisal, investment banking, and similar professional fees and charges) incurred by the Purchaser in connection with the enforcement of or preservation of rights under this Agreement and the other Related Documents. The Fund shall not be responsible under this Section 7.3(a) for the fees and costs of more than one law firm in any one jurisdiction with respect to any one proceeding or set of related proceedings for the Purchaser, unless the Purchaser shall have reasonably concluded that there are legal defenses available to it that are different from or additional to those available to the Fund.

	(b)	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 and expenses incurred by them (including reasonable fees and disbursements of outside counsel) which (i) are related to or arise out of (A) any untrue statements or alleged untrue statements made or any statements omitted or alleged to have been omitted to be made in the Memorandum (including any documents incorporated by reference therein), (B) actions taken or omitted to be taken by the Fund in connection with the transactions contemplated by this Agreement and the Variable Rate Mode Supplement, (C) actions taken or omitted to be taken by the Purchaser or another Indemnified Person of the Purchaser at the indemnifying party’s direction or with the indemnifying party’s consent or (ii) are otherwise related to or arise out of or in connection with, the proposed transactions giving rise to or contemplated by this Agreement (including, without limitation, pursuant to the other Related Documents), including modifications or future additions to this Agreement and the other Related Documents, or other related activities, including the acquisition by the Purchaser of Additional MFP Shares that are subject to prior liens, security interests or claims of any Person other than the Purchaser, except for consensual liens or other security interests as may be created by the Purchaser (and the Purchaser agrees that the rights of the Fund shall be subrogated to the rights of the Purchaser in respect of any payments made in respect of any such prior liens, security interests or claims to the extent of any indemnification payments made by the Fund), and to promptly reimburse any Indemnified Person of the Purchaser for all expenses (including reasonable fees and disbursements of outside counsel) as incurred by such Indemnified Person in connection with investigating, preparing or defending any such action or claim, whether or not in connection with pending or threatened litigation in which any such Indemnified Person is a party. The indemnifying party will not, however, be responsible for any losses, claims, damages, liabilities or expenses of any such Indemnified Person to the extent the same resulted pursuant to clause (ii) of the preceding sentence to the extent the same resulted from the gross negligence, bad faith or willful misconduct of such Indemnified Person, as determined in a non-appealable final judgment by a court of competent jurisdiction.

	(c)	The indemnifying party 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 in respect of any losses, claims, damages or liabilities (or actions in respect thereof), then the indemnifying party, 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 losses, claims, liabilities, damages and expenses (or actions in respect thereof) 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, in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages, liabilities or expenses (or actions in respect thereof), 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 losses, claims, damages, liabilities and 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 value received or proposed to be received by the Fund pursuant to the transactions, whether or not consummated bears to (ii) the dividends and Optional Redemption Premium, if any, paid by the Fund to the Purchaser in connection with the proposed transactions giving rise to or contemplated by this Agreement. The relative fault of the parties shall be determined by reference to, among other things, whether the actions taken or omitted to be taken in connection with the proposed transactions contemplated by this Agreement (including any misstatement of a material fact or the omission to state a material fact) relates to information supplied by the Fund on the one hand, or the Purchaser on the other, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, misstatement or alleged omission, and any other equitable considerations appropriate in the circumstances. 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 any action, suit, proceeding or investigation is commenced, as to which an Indemnified Person proposes to demand indemnification, it shall notify the indemnifying party with reasonable promptness; provided, however, that any failure by such Indemnified Person to notify the indemnifying party shall not relieve the indemnifying party from its obligations hereunder (except to the extent that the indemnifying party is materially prejudiced by such failure to promptly notify). The indemnifying party 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 indemnifying party 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 indemnifying party 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 indemnifying party; provided, however, that the indemnifying party 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 such other party; and such counsel shall, to the extent consistent with its professional responsibilities, cooperate with the indemnifying party and any counsel designated by the indemnifying party.

Each party further agrees that it will not, without the prior written consent of the other party (the consent of a party shall not be required to the extent such party is neither requesting indemnification nor being requested to provide indemnification), 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 the Fund (if such settlement, compromise or consent is agreed to by the Purchaser or another Indemnified Person) or the Purchaser and each other Indemnified Person (if such settlement, compromise or consent is agreed to by the Fund) from all liability and obligations arising therefrom. The Fund further agrees that neither the Purchaser, nor any of its affiliates, or 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 except for such liability for losses, claims, damages, liabilities or expenses to the extent they have resulted from the Purchaser’s or its affiliates’ gross negligence or willful misconduct. No Indemnified Person shall be responsible or liable to the indemnifying party or any other person for consequential, special or punitive damages which may be alleged as a result of this Agreement.

Nothing in this Section 7.3 is intended to limit either party’s obligations contained in other parts of this Agreement or the MFP Shares.

ELIGIBLE ASSETS

On the Effective Date and at all times thereafter:

1.	All assets in the Fund consist and will consist of “Eligible Assets,” defined to consist only of the following as of the time of investment:

A. Debt obligations

i. “Municipal securities,” defined as obligations (whether documented as securities or as loans) of a State, the District of Columbia, a U.S. territory, or a political subdivision thereof and including general obligations, limited obligation bonds, revenue bonds, and obligations that satisfy the requirements of section 142(b)(1) of the Internal Revenue Code of 1986 issued by or on behalf of any State, the District of Columbia, any U.S. territory or any political subdivision thereof, including any municipal corporate instrumentality of one or more States, or any public agency or authority of any State, the District of Columbia, any U.S. territory or any political subdivision thereof, including, for example, where otherwise consistent with the securities described in this paragraph, securities financing a 501(c)(3) organization. The purchase of any municipal security will be based upon the Investment Adviser’s assessment of an asset’s relative value in terms of current yield, price, credit quality, and future prospects; and the Investment Adviser will monitor the creditworthiness of the Fund’s portfolio investments and analyze economic, political and demographic trends affecting the markets for such assets.

Eligible Assets shall include any municipal securities that at the time of purchase are paying scheduled principal and interest or if at the time of purchase are in payment default, then in the sole judgment of the Investment Adviser are expected to produce payments of principal and interest whose present value exceeds the purchase price.

ii. Debt obligations of the United States.

iii. Debt obligations issued, insured, or guaranteed by a department or an agency of the U.S. Government, if the obligation, insurance, or guarantee commits the full faith and credit of the United States for the repayment of the obligation.

iv. Debt obligations of the Washington Metropolitan Area Transit Authority guaranteed by the Secretary of Transportation under Section 9 of the National Capital Transportation Act of 1969.

v. Debt obligations of the Federal Home Loan Banks.

vi. Debt obligations, participations or other instruments of or issued by the Federal National Mortgage Association or the Government National Mortgage Association.

vii. Debt obligations which are or ever have been sold by the Federal Home Loan Mortgage Corporation pursuant to sections 305 or 306 of the Federal Home Loan Mortgage Corporation Act.

viii. Debt obligations of any agency named in 12 U.S.C. § 24(Seventh) as eligible to issue obligations that a national bank may underwrite, deal in, purchase and sell for the bank’s own account, including qualified Canadian government obligations.

ix. Debt obligations of issuers other than those specified in (i) through (viii) above where the Fund and its advisers have reasonably determined that the issuer of the security has an adequate capacity to meet financial commitments under the security for the projected life of the asset or exposure. An issuer has an adequate capacity to meet financial commitments if the risk of default by the obligor is low and the full and timely repayment of principal and interest is expected. In addition, such debt obligations must be rated in one of the three highest rating categories by two or more NRSROs, or by one NRSRO if the security has been rated by only one NRSRO, or otherwise of equivalent quality based on the Fund’s internal credit due diligence, and must be “marketable.” For these purposes, an obligation is “marketable” if:

	·	it is registered under the Securities Act;
	·	is a municipal revenue bond exempt from registration under the Securities Act of 1933, 15 U.S.C. 77c(a)(2);
	·	it is offered and sold pursuant to Securities and Exchange Commission Rule 144A; 17 CFR 230.144A; or
	·	it can be sold with reasonable promptness at a price that corresponds reasonably to its fair value.

x. Certificates or other securities evidencing ownership interests in a municipal bond trust structure (generally referred to as a tender option bond structure) that invests in (a) debt obligations of the types described in (i) above or (b) depository receipts reflecting ownership interests in accounts holding debt obligations of the types described in (i) above.

An asset shall not lose its status as an Eligible Asset solely by virtue of the fact that:

	·	it provides for repayment of principal and interest in any form including fixed and floating rate, zero interest, capital appreciation, discount, leases, and payment in kind; or

	·	it is for long-term or short-term financing purposes.

B. Derivatives

	i.	Interest rate derivatives held for hedging purposes;

	ii.	Swaps, futures, forwards, structured notes, options and swaptions related to Eligible Assets or on an index related to Eligible Assets; or

	iii.	Credit default swaps held for hedging purposes.

	iv.	The Fund will not invest, trade or underwrite any equity-related derivatives or commodity-related derivatives.

C. Other Assets

	i.	Shares of other investment companies (open- or closed-end funds and ETFs) the assets of which consist entirely of Eligible Assets based on the Investment Adviser’s assessment of the assets of each such investment company taking into account the investment company’s most recent publicly available schedule of investments and publicly disclosed investment policies.

	ii.	Cash.

	iii.	Repurchase agreements on assets described in A above.

	iv.	Assets not otherwise covered in A, B or C above that the Investment Adviser or the Sub-Adviser may determine are in the best interest of shareholders of the Fund to acquire in pursuing a workout arrangement with issuers (of the types described in A above) of defaulted obligations, including, but not limited to, loans to the defaulted issuer or another party pursuant to the workout arrangement, or a debt, equity or other interest in the defaulted issuer or other party.

D. Other assets, upon written agreement of the Purchaser that such assets are eligible for purchase by the Purchaser.

2.	The Investment Adviser has instituted policies and procedures that it believes are sufficient to ensure that the Fund and it comply with the representations, warranties and covenants contained in this Exhibit to the Agreement.

3.	The Fund will, upon request, provide the Purchaser and its internal and external auditors and inspectors as the Purchaser may from time to time designate, with all reasonable assistance and access to information and records of the Fund relevant to the Fund’s compliance with and performance of the representations, warranties and covenants contained in this Exhibit to the Agreement, but only for the purposes of internal and external audit.

4.	In the event that any of the foregoing cease to be eligible investments for purposes of 12 U.S.C. 24(7) and 12 C.F.R. Part 1 (“National Bank Law”), as and to the extent permitted by National Bank Law, following written notice to the Fund from the Purchaser: (a) the Fund and the Purchaser shall promptly consult with each other to amend this Exhibit to address the changes in National Bank Law, during which time, commencing promptly following receipt of such notice, the Fund shall no longer purchase any securities that are no longer eligible investments under such National Bank Law as specified in such notice; and (b) the Fund shall use its reasonable efforts to bring the Fund’s existing investments in any securities, if any, that no longer are Eligible Assets into conformity with Eligible Assets, as that term is modified by such notice and is then in effect, consistent with the Fund’s investment objectives, policies and the Fund’s or the Fund’s Investment Adviser’s determination of the best interests of the Fund and its shareholders.]
