ATTACHMENT B

ELIGIBLE ASSETS

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:

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 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 issuers other than those specified in (i) through (viii) above that are “investment grade” and that are “marketable.” For these purposes, an obligation is:

(a) “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

(b) “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 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.

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.

B. Derivatives

i. 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.

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.
