<P ALIGN="CENTER">CAPITAL SUPPORT AGREEMENT</P>

<P>	THIS CAPITAL SUPPORT AGREEMENT (this "Agreement") is made as of the 30th day of June, 2008, by and among Legg Mason, Inc., a Maryland corporation ("Legg Mason"), LM Capital Support V, LLC, a Maryland limited liability company ("LMSub" and, together with Legg Mason, the "Support Providers"), and Western Asset Money Market Fund, a series of Legg Mason Partners Money Market Trust (the "Fund").</P>

<P>WITNESSETH:</P>

<P>	WHEREAS, Legg Mason Partners Money Market Trust is an investment company registered with the Securities and Exchange Commission in accordance with the Investment Company Act of 1940 (as amended, the "1940 Act");</P>

<P>	WHEREAS, the Fund is a money market fund that seeks to maintain a stable net asset value using the Amortized Cost Method as defined in and in accordance with Rule 2a-7 promulgated under the 1940 Act (as amended, "Rule 2a-7");</P>

<P>	WHEREAS, the Fund holds notes and other instruments (the "Notes") issued by structured investment vehicles listed in Schedule A attached hereto (each, an "Issuer");</P>

<P>	WHEREAS, Rule 2a-7(c)(6)(ii) requires a money market fund to "dispose of [a portfolio] security as soon as practicable consistent with achieving an orderly disposition of the security, . . ., absent a finding by the board of directors that disposal of the portfolio security would not be in the best interests of the money market fund (which determination may take into account, among other factors, market conditions that could affect the orderly disposition of the portfolio security)" upon the occurrence of certain events;</P>

<P>	WHEREAS, one or more of the events specified in Rule 2a-7(c)(6)(ii) have occurred with respect to the Notes;</P>

<P>	WHEREAS, a sale of the Notes under current market conditions is unlikely to result in the full recovery of the Fund's investments, and may cause the Fund to realize losses;</P>

<P>	WHEREAS, Legg Mason is the sole stockholder of the Fund's manager and LMSub is a subsidiary of Legg Mason;</P>

<P>		(d) The obligations of the Support Providers to make Capital Contributions hereunder shall be joint and several.
