NEW YORK, Oct 02, 2008 (BUSINESS WIRE) -- The Boards of Directors/Trustees for the UBS U.S. Money Market Funds
named below (the "Funds")
on October 1, 2008, approved the participation of those money market
funds in the U.S. Treasury's Temporary
Guarantee Program. All of these Funds will apply to be covered under the
program.

"We recognize the U.S. Treasury's
actions to address what are believed to be temporary dislocations in the
credit markets," said Kai Sotorp, Head
Americas, UBS Global Asset Management. "While
the UBS money market funds have maintained their $1 net asset value
throughout the recent unprecedented turmoil and continued to meet their
stated goals of capital preservation, liquidity and income, we are
pleased to have the Funds participate in the U.S. Treasury's
Temporary Guarantee Program to provide an added level of protection for
covered shareholders." The Funds continue to
operate normally, and maintain a stable net asset value of $1 per share.

Through this program, the U.S. Treasury will guarantee the share price
of any eligible money market mutual fund--whether
retail or institutional--that applies for and
pays a fee to participate in the program. Eligible funds are those that
are regulated pursuant to Rule 2a-7 under the Investment Company Act of
1940, have maintained a stable share price of $1, and are publicly
offered and registered with the Securities and Exchange Commission.
Shareholders will be covered for the value of shares they held in
accounts in the participating money market funds as of the close of
business on September 19, 2008.

Following is a list of the money market funds that will apply to be
insured under the program:
