RESOLVED:		That the appropriate officers of the Fund be, and each hereby is, authorized and directed to take and/or ratify all necessary action for the Fund to become a member of ICI Mutual Insurance Company (“ICI Mutual”) and, in conjunction with other investment companies for which affiliates of LMPFA serve as investment adviser and/or administrator, to purchase from ICI Mutual fidelity bond coverage (“Joint Fidelity Bond”) and a Directors and Officers/Errors and Omissions (“D&O/E&O”) liability insurance policy to which the investment adviser, sub-adviser, principal underwriter, administrator, directors and/or officers of such investment companies may also be parties; and further

RESOLVED:		That it is the finding of the Board that the Joint Fidelity Bond covering, among others, officers and employees of the Fund in accordance with the requirements of Rule 17g-1 under the 1940 Act is reasonable in form and amount, after having given due consideration to, among other things, the value of the aggregate assets of the Fund to which any person covered under the Joint Fidelity Bond may have access, the type and terms of the arrangements made for the custody and safekeeping of the Fund’s assets and the nature of the securities in the Fund’s portfolio; and further

RESOLVED:		That the portion of the total premium for the Joint Fidelity Bond to be allocated to the Fund based on its net assets (following the public offering of its Common Stock) be, and hereby is, approved by a vote of a majority of the Board of Directors of the Fund (all Directors voting) and separately by a majority of the “non-interested” Directors, after having given due consideration to, among other things, the number of the other parties named as insureds, the nature of the business activities of such other parties, the amount of the Joint Fidelity Bond, the amount of the premiums for the Fidelity Bond, the ratable allocation of the premiums among all parties named as insureds, and the extent to which the share of the premium allocated to the Fund is less than the premium the Fund would have had to pay if it had provided and maintained a fidelity bond which covers only the Fund as the insured; and further

RESOLVED:		That the Joint Fidelity Bond be, and hereby is, approved by a vote of the Board of Directors (all Directors voting) and separately by the “non-interested” Directors; and further

RESOLVED:		That the officers of the Fund be, and each of them hereby is, authorized and directed to enter into an agreement, in substantially the form used for the Closed-end Funds, as required by paragraph (f) of Rule 17g-1 under the 1940 Act with the other named insureds under the Joint Fidelity Bond providing that in the event any recovery is received under the Bond as a result of a loss sustained by the Fund and also by one or more of the other named insureds, the Fund shall receive an equitable and proportionate share of the recovery, but in no event less than the amount it would have received had it obtained and maintained a single insured bond with the minimum coverage required by paragraph (d) (1) of such Rule 17g-1; and further

RESOLVED:		That the appropriate officers of the Fund be, and each of them hereby is, authorized and directed to prepare, execute and file such amendments and supplements to the aforesaid agreement, and to take such other action as may be necessary or appropriate in order to conform to the provisions of the 1940 Act and the rules and regulations thereunder; and further

RESOLVED:		That the Secretary of the Fund shall file the Joint Fidelity Bond with the Securities and Exchange Commission and give the notices required under paragraph (g) of Rule 17g-1 under the 1940 Act.
