Supplement No. 1 dated May 29, 1997
to
Prospectus dated August 1, 1996
for
STATE STREET RESEARCH MONEY MARKET FUND
a series of State Street Research Money Market Trust
The Fund has been advised that the Distributor and its affiliates have
increased their voluntary assumption of some portion of fees or expenses
relating to the Fund, which will have the effect of reducing Total Fund
Operating Expenses for each class of shares to the following levels:
Class B Class C Class D Class E
1.65% 0.65% 1.65% 0.65%
For the fiscal year ended March 31, 1996, Total Fund Operating Expenses
as a percentage of average net assets of Class B, Class C, Class D and Class E
shares, respectively, were 1.75%, 0.75%, 1.75% and 0.75%. Based solely on the
actual expense levels for the fiscal year ended March 31, 1996, this increase in
the assumption of expenses will have the effect of reducing expenses for each
class of shares by 0.10%. See the Table of Expenses on page 2 of the Prospectus
for further information. The Fund expects the subsidization to continue for the
current fiscal year, although it cannot give complete assurance that such
assistance will continue.
The "Example" on page 3 of the Prospectus, showing expenses an investor
would pay under certain assumptions, is supplemented as follows to reflect the
reduced expenses:
"You would pay the following expenses on a $1,000 investment, assuming
(1) 5% annual return and (2) redemption of the entire investment at the end of
each time period:
1 Year 3 Years 5 Years 10 Years
Class B shares (1) $67 $82 $110 $169
Class C shares $ 7 $21 $ 36 $ 81
Class D shares $27 $52 $ 90 $195
Class E shares $ 7 $21 $ 36 $ 81
You would pay the following expenses on the same investment, assuming
no redemption:
1 Year 3 Years 5 Years 10 Years
Class B shares (1) $17 $52 $90 $169
Class D shares $17 $52 $90 $195
_____________________________
(1) Ten-year figures assume conversion of Class B shares to Class E shares at
the end of eight years."
