7.2	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, the New VMTP Shares or any other Related Document). The rights of Banc of America hereunder are separate from and in addition to any rights that any Holder or Designated Owner of any New VMTP Share may have under the terms of such New VMTP Share or any Related Document or otherwise.

(b)

No failure or delay by the Fund or Banc of America in exercising any right, power or privilege hereunder or under the New VMTP 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 Banc of America in exercising any right, power or privilege under or in respect of the New VMTP Shares or any other Related Document shall affect the rights, powers or privileges of the Fund or Banc of America hereunder 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.

7.3	Expenses and Indemnification

(a)

The Fund shall upon demand either, as Banc of America may require, pay in the first instance or reimburse Banc of America (to the extent that payments for the following items are not made under the other provisions hereof) for all reasonable out-of-pocket expenses (including reasonable fees and costs of outside counsel, and reasonable consulting, accounting, appraisal, investment banking, and similar professional fees and charges) incurred by Banc of America in connection with the enforcement of or preservation of rights under this Agreement. 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 Banc of America, unless Banc of America 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 Banc of America and each other Indemnified Person of Banc of America from and against any losses, claims, damages, liabilities and reasonable out-of-pocket expenses incurred by them (including reasonable fees and disbursements of outside counsel which are related to or arise out of (A) any material misstatements or any material statements omitted to be made in the Information Memorandum (including any documents incorporated by reference therein) or (B) any claim by any third party relating to the Exchange of the Old VMTP Shares for the New VMTP Shares by the Fund or the holding of the New VMTP Shares by Banc of America (x) that Banc of America aided and abetted a breach of a fiduciary duty by the Fund or any director or officer of the Fund or (y) arising from any act by the Fund or any director or officer of the Fund (excluding in any such case clauses (A) or (B), claims, losses, liabilities or expenses arising out of or resulting from the gross negligence or willful misconduct of any Indemnified Party as determined 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 of such other party 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 Banc of America 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 Banc of America 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 Banc of America 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 Banc of America 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 Banc of America 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 paid by the Fund to Banc of America 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 Banc of America 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.

ELIGIBLE ASSETS

On the Effective Date and at all times thereafter:

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

Debt obligations

i. “Municipal securities,” defined as obligations 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 1 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 obligations of any of the foregoing types related to 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 the Fund other than those specified in (i) through (viii) above that are “investment grade” and that are “marketable.” For these purposes, an obligation is:

(aa) “marketable” if:

•

it is registered under the Securities Act;

•

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; and

(bb) “investment grade” if:

•

the obligor had adequate capacity to meet financial commitments under the security for the projected life of the asset or exposure, which capacity is presumed if the risk of default by the obligor is low and the full and timely repayment of the principal and interest is expected.

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.

xi. The bonds, notes and other debt securities referenced in (A) above shall be defined as Eligible Assets. 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.

Derivatives

Interest rate derivatives;

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.

Other Assets

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; or

iv.

Taxable fixed-income securities, for the purpose of acquiring control of an Fund whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate that such investment should enable the Fund to better maximize its existing investment in such Fund, provided that the Fund may invest no more than 0.5% of its total assets in such securities.

Other assets, upon written agreement of Banc of America that such assets are eligible for purchase by Banc of America.

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 B to the Agreement.

The Fund will, upon request, provide Banc of America and its internal and external auditors and inspectors as Banc of America 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 B to the Agreement, but only for the purposes of internal and external audit.
