THE FUND
- ------------------------------------------------------------------------------

  The Fund is an open-end,  diversified management investment company,  commonly
known as a mutual fund. The Fund has been operating continuously since September
22,  1975,  when  it was  created  under  Massachusetts  law as a  Massachusetts
business  trust.  The Fund is one of  twenty-nine  funds  managed  or advised by
Keystone Investment Management Company (formerly Keystone Custodian Funds, Inc.)
("Keystone"), the Fund's investment adviser.
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------

  The Fund's  investment  objective  is to  provide  shareholders  with  maximum
current  income  while  preserving  capital.  To meet this  objective,  the Fund
currently offers only the Portfolio.

  The Fund is designed for  institutional  and other  substantial  investors who
wish to keep temporary cash balances invested in money market instruments. Since
the Portfolio is fully  diversified  among many securities,  investors may incur
less risk by investing in the  Portfolio  than by investing  directly in a small
number of  instruments.  Investors also achieve  liquidity since the Portfolio's
shares may be redeemed at any time.  Furthermore,  investors are relieved of the
administrative  tasks of  collecting  income and  reinvesting  the  proceeds  of
matured securities and receive detailed records of their accounts.

  The  Portfolio  invests in money market  instruments  maturing in 397 calendar
days or less and/or U.S. government  securities maturing in 762 calendar days or
less and maintains an average dollar-weighted maturity of 90 days or less.

  The Portfolio  limits its investments,  including  repurchase  agreements,  to
those U.S.  dollar-denominated  instruments  that  Keystone  determines  present
minimal  credit  risks and are at the time of  acquisition  eligible  securities
("Eligible Securities") as defined under Rule 2a-7 of the Investment Company Act
of 1940 (the "1940 Act").  Eligible  Securities  include (1) securities rated by
the  requisite  rating  agencies  at the  date of  investment  in one of the two
highest short-term rating  categories;  (2) securities of issuers receiving such
rating with respect to other  short-term  debt  securities;  (3) and  comparable
unrated  securities.  Requisite rating agencies means any two agencies that have
issued a rating with  respect to a security or class of debt  obligations  of an
issuer or one rating  agency if only one agency has issued a rating with respect
to such  security or issuer.  If the  Portfolio  purchases  securities  that are
unrated or that have been rated by a single rating agency,  the purchase must be
approved or ratified by the Fund's Board of Trustees.

  The short-term  ratings are as follows:  A-1 and A-2, the two highest  ratings
given by Standard & Poor's  Corporation  ("S&P");  Prime-1 and Prime-2,  the two
highest ratings given by Moody's Investors Service,  Inc.  ("Moody's");  and F-1
and F-2, the two highest ratings given by Fitch Investors Service, Inc.
("Fitch").


  While the Portfolio may purchase single rated or unrated securities,  the Fund
anticipates  that at least 95% of the  Portfolio's  assets  will be  invested in
instruments  that  at the  date of  investment  are  rated  or  deemed  to be of
comparable  quality  to  securities  rated  in  the  highest  short-term  rating
categories by any two rating  agencies.  The Portfolio will not invest more than
5% of its assets in securities  issued by any one issuer,  except for securities
issued or guaranteed by the U.S. government,  its agencies or instrumentalities,
nor will it invest more than 1% of its assets in securities  rated in the second
highest  short-term rating category issued by any one issuer. The Portfolio will
not invest more than 5% of its assets in securities  rated in the second highest
short-term rating category.

  The Fund is  presently  authorized  by the  Board of  Trustees  to  invest  in
short-term municipal  obligations.  The Portfolio will only invest in short-term
municipal  obligations  when  such  investment  is  consistent  with the  Fund's
investment objective and the Portfolio's investment policies. The Board has also
authorized  the purchase by the Fund of U.S.  dollar-denominated  obligations of
foreign  branches of foreign banks when such investments  otherwise  satisfy the
investment criteria of the Fund.

  The Portfolio  invests in the following types of  instruments:  (1) commercial
paper,  including  master demand notes and loan  participation  agreements;  (2)
obligations  issued or  guaranteed  by the U.S.  government  or by any agency or
instrumentality of the U.S. government;  (3) obligations (including U.S., Yankee
and Eurodollar  certificates of deposit, time deposits and bankers' acceptances)
of domestic and foreign banks or savings and loan associations provided that (a)
at the time of investment,  the depository  institution or guarantor bank has at
least $1  billion  in  assets  (as of the date of its  most  recently  published
financial statements),  or (b) the principal amount of the instrument is insured
in full by the Federal Deposit  Insurance  Corporation;  (4) obligations that at
the date of investment are rated AA or better by S&P or Aa or better by Moody's;
and (5) repurchase agreements for any security listed above.

  To the extent permitted by its investment  policies,  the Portfolio may invest
in restricted  securities,  including securities eligible for resale pursuant to
Rule 144A under the  Securities  Act of 1933 (the "1933 Act").  Generally,  Rule
144A  establishes a safe harbor from the  registration  requirements of the 1933
Act for resales by large  institutional  investors  of  securities  not publicly
traded in the U.S. The  Portfolio may purchase  Rule 144A  securities  when such
securities present an attractive  investment  opportunity and otherwise meet the
Portfolio's  selection  criteria.  Keystone  determines  the  liquidity  of  the
Portfolio's  Rule 144A securities in accordance  with guidelines  adopted by the
Board of Trustees.


  At the present time, the Fund cannot accurately predict exactly how the market
for Rule 144A  securities  will  develop.  A Rule 144A security that was readily
marketable upon purchase may subsequently become illiquid. In such an event, the
Board of Trustees will consider what action, if any, is appropriate.


  Because  interest rates on money market  instruments  fluctuate in response to
economic factors, the rates on short-term  investments made by the Portfolio and
the  daily  dividend  paid to  investors  will  vary,  rising  or  falling  with
short-term  rates  generally.   Also,  yields  from  short-term  securities  may
frequently be lower than yields from longer term  securities.  In addition,  the
value of the  Portfolio's  securities  will  fluctuate  inversely  with interest
rates, the amount of outstanding debt and other factors.


  For a  further  explanation  about  the types of  investments  and  investment
techniques  available to the Portfolio,  including the associated risks,  please
refer to the description of such  investments  and investment  techniques at the
back of this prospectus as well as the statement of additional information.
  Of course, there can be no assurance that the Fund will achieve its investment
objective since there is uncertainty in every investment.

- ------------------------------------------------------------------------------
INVESTMENT RESTRICTIONS
- ------------------------------------------------------------------------------

  The Fund has adopted the fundamental  restrictions summarized below, which may
not be changed without the vote of a majority of the Fund's outstanding  shares.
These  restrictions and certain other fundamental  restrictions are set forth in
detail in the statement of additional information.  Unless otherwise stated, all
references to the Fund's assets are in terms of current market value.

  Generally,  the Fund will not do the following: (1) invest more than 5% of its
assets in the securities of other single issuers;  (2) borrow money, except that
the Fund may borrow money from banks for extraordinary or emergency  purposes in
amounts up to one-third  (normally less than 5%) of its total assets,  including
the  amount  borrowed,  and such  borrowings  will be repaid  before  additional
investments  are made;  (3) pledge  more than 15% of its total  assets to secure
borrowings;   and  (4)  purchase  any  security,   other  than  U.S.  government
securities,  if as a result more than 25% of the Fund's  total  assets  would be
invested in a single industry, except that the Fund may invest up to 100% of its
assets in finance  companies as a group,  banks and bank holding  companies as a
group and utility companies as a group.


  Notwithstanding  the more flexible limits set forth above, the Fund deems each
of its  fundamental  investment  restrictions to apply to the investments of the
Portfolio.  Moreover,  notwithstanding  the  freedom  reserved  by the  Fund  to
concentrate  all of  its  assets  in  finance  companies,  banks,  bank  holding
companies and utilities, the Portfolio (if permitted by its investment policies)
may invest up to 100% of its assets only in (1) securities  issued or guaranteed
by the U.S. government,  its agencies or instrumentalities;  and (2) instruments
issued by a domestic  bank  (including a foreign  branch of a domestic  bank for
which the investment risk  associated with the securities  issued by such branch
is the same as the investment risk associated with the securities  issued by its
domestic  parent as well as a U.S.  branch of a foreign  bank that is subject to
the same regulation as U.S. banks).

  In addition, the Fund has a policy that the Portfolio will not invest more
than 10% of its  total  assets  in  illiquid  securities,  including  repurchase
agreements maturing in more than seven days.


- ------------------------------------------------------------------------------
PRICING SHARES
- ------------------------------------------------------------------------------


  Transactions  in the  money  market  instruments  in which  the  Fund  invests
normally require immediate settlement in federal funds. The Portfolio intends to
be as fully invested as is reasonably practicable in order to maximize the yield
on its portfolio assets.  Accordingly,  all payments must be in federal funds or
other funds  available  to the Fund that day. If  notification  of the  purchase
order is received by 12:00 Noon (eastern time) and federal  funds or other funds
available  to the Fund that day are  received by wire on a day on which banks in
both Boston and New York City are open for business,  the purchase order will be
accepted that day. The shares purchased will be entitled to that day's dividend.
Other orders will be accepted and will become entitled to dividends  declared on
the next bank business day after receipt of payment.

  The net asset value per share of the  Portfolio is computed as of the close of
trading on the New York Stock  Exchange (the  "Exchange")  (currently  4:00 p.m.
eastern time for purposes of pricing  Portfolio shares) on each day on which the
Exchange is open,  except on days when  changes in the value of the  Portfolio's
securities  do not affect the net asset  value of its  shares.  The  Exchange is
currently  closed on weekends,  New Year's Day,  Presidents'  Day,  Good Friday,
Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day and Christmas Day.
The net asset value per share of the Portfolio is determined by adding the value
of all  securities  and  other  assets  held  by the  Portfolio,  deducting  the
liabilities  chargeable  to the  Portfolio,  including  its share of the general
liabilities  of the Fund, and dividing the result by the number of shares of the
Portfolio outstanding.

  Since the net income of the  Portfolio is declared as a dividend each time net
income is determined,  the net asset value per share of the Portfolio is rounded
to the  nearest  penny  daily  and is  expected  to  remain  at $1.00  per share
immediately after each dividend declaration. The Fund expects to have net income
at the  time of each  dividend  determination  for the  Portfolio.  If,  for any
reason,  there is a net loss in the  Portfolio,  the Fund will first offset such
amount pro rata against  dividends  accrued during the month in each shareholder
account.  To the extent that such a net loss would exceed such accrued dividends
for the  Portfolio,  the Fund will  reduce the number of  outstanding  shares by
having each  shareholder  of the Portfolio  contribute to the Fund's capital his
pro rata portion of the total number of shares required to be cancelled in order
to maintain a net asset value of $1.00 for the Portfolio.  Each shareholder will
be deemed to have agreed to such a contribution  in these  circumstances  by his
investment in the Portfolio.

  Securities  purchased  with  maturities  of sixty  days or less are  valued at
amortized cost (original  purchase cost as adjusted for  amortization of premium
or  accretion  of  discount),   which,  when  combined  with  accrued  interest,
approximates  market;  securities  maturing  in more than  sixty  days for which
market  quotations are readily available are valued at current market value; and
securities maturing in more than sixty days when purchased, that are held on the
sixtieth day prior to maturity,  are valued at amortized  cost (market  value on
the sixtieth day adjusted for amortization of premium or accretion of discount),
which,  when combined with accrued  interest,  approximates  market; in any case
reflecting  fair  value as  determined  by the  Board  of  Trustees.  All  other
investments  are valued at market  value or,  where  market  quotations  are not
readily  available,  at fair value as  determined  in good faith by the Board of
Trustees.

- ------------------------------------------------------------------------------
DIVIDENDS AND TAXES
- ------------------------------------------------------------------------------

  The  Portfolio  has  qualified  and  intends  to  qualify  in the  future as a
regulated  investment  company under the Internal  Revenue  Code.  The Portfolio
qualifies if, among other things,  it distributes to its  shareholders  at least
90% of its net investment income for its fiscal year. The Portfolio also intends
to make timely  distributions,  if necessary,  sufficient in amount to avoid the
nondeductible  4% excise tax  imposed on a regulated  investment  company to the
extent that it fails to distribute, with respect to each calendar year, at least
98% of its  ordinary  income for such  calendar  year and 98% of its net capital
gains for the one-year  period ending on October 31 of such calendar  year.  Any
taxable  distribution would be (1) declared in October,  November or December to
shareholders  of record in such a month,  (2) paid by the following  January 31,
and (3) includable in the taxable income of  shareholders  for the year in which
such  distributions  were  declared.  If  the  Portfolio  qualifies  and  if  it
distributes  all of its net investment  income and net capital gains, if any, to
shareholders,  it will be  relieved  of any federal  income tax  liability.  The
Portfolio  will  make  distributions  from  its  net  investment  income  to its
shareholders  by the 15th day of each month and net  capital  gains,  if any, at
least annually.

  Dividends  distributed  by the  Portfolio  will be  automatically  invested in
additional shares of the Portfolio unless the shareholder elects to receive them
in cash.  Dividends  are  taxable as  ordinary  income to  shareholders  who are
subject  to  federal  income  taxes and may also be  subject  to state and local
taxes. The Fund does not expect to realize any capital gains or losses. The Fund
advises  its  shareholders  annually  as  to  the  federal  tax  status  of  all
distributions made during the year.

PORTFOLIO MANAGEMENT AND EXPENSES
- ------------------------------------------------------------------------------

BOARD OF TRUSTEES
  Under  Massachusetts  law,  the Fund's  Board of  Trustees  has  absolute  and
exclusive control over the management and disposition of all assets of the Fund.
Subject to the authority of the Board of Trustees, Keystone serves as the Fund's
investment  adviser and, in general,  supervises  the  management and investment
program of the Portfolio.

INVESTMENT ADVISER
  Keystone,  located at 200 Berkeley Street, Boston,  Massachusetts  02116-5034,
has provided investment advisory and management services to investment companies
and private accounts since it was organized in 1932.  Keystone is a wholly-owned
subsidiary of Keystone Investments, Inc. ("Keystone Investments"),  200 Berkeley
Street, Boston, Massachusetts 02116-5034.

  Keystone  Investments  is a  corporation  predominantly  owned by  former  and
current  members of  management  of Keystone and its  affiliates.  The shares of
Keystone Investments common stock beneficially owned by management are held in a
number of voting trusts, the trustees of which are George S. Bissell,  Albert H.
Elfner, III, Edward F. Godfrey and Ralph J. Spuehler,  Jr. Keystone  Investments
provides  accounting,   bookkeeping,  legal,  personnel  and  general  corporate
services to Keystone  Management,  Inc.,  Keystone,  their  affilitates  and the
Keystone Investments Family of Funds.

  Pursuant to its  Investment  Advisory  Agreement  with the Fund (the "Advisory
Agreement")  ,  Keystone  provides  investment   management  and  administrative
services to the  Portfolio.  Such services  include  managing the investment and
reinvestment of the  Portfolio's  assets as well as providing the Portfolio with
office space, facilities, equipment and personnel.

  Under the terms of the Advisory Agreement, Keystone is generally entitled to a
management fee,  payable  quarterly,  equal to (1) 5% of the gross income of the
Portfolio,  less (2) the  amount  of the net  expenses  of the  Fund  (excluding
Keystone's  compensation,  interest,  taxes, brokerage commissions,  fees of the
Fund's independent Trustees and extraordinary expenses).

PORTFOLIO EXPENSES
  On October 1, 1990,  Keystone  voluntarily  limited its  management fee for an
indefinite  period to a maximum annual rate of 0.20% of the Portfolio's  average
daily  net  assets.  Keystone  may,  after  notice  to  shareholders,  change or
eliminate this voluntary fee limitation.  In addition,  commencing  December 28,
1992,  Keystone  voluntarily  limited  its  advisory  fee  with  respect  to the
Portfolio  to an annual  rate of 0.09% of the  Portfolio's  average  net assets.
Keystone  expects to maintain  this  voluntary  limitation  until the end of the
Fund's  fiscal year, at which time, a  determination  of whether to continue the
limitation and, if so, at what rate will be made.  Keystone continues to pay the
Fund's normal operating expenses,  excluding Keystone's compensation,  interest,
taxes, brokerage commissions and extraordinary expenses.

  During the year ended  December  31, 1994,  the Fund,  in  aggregate,  paid or
accrued  to  Keystone  investment  management  and  advisory  services  fees  of
$148,293,  which amount  includes  amounts paid with respect to portfolios  that
became inactive during such period. Of such amount paid to Keystone, $49,118 was
paid to Keystone  for services to Money  Market  Portfolio I, which  represented
0.09% of the Portfolio's average daily net assets.

PORTFOLIO MANAGER

  Barbara A.  McCue is the  Fund's  portfolio  manager.  She is a Keystone  Vice
President  and Senior  Portfolio  Manager with more than 19 years of  investment
experience.

SECURITIES TRANSACTIONS

  Under  policies  established  by  the  Board  of  Trustees,  Keystone  selects
broker-dealers  to execute  portfolio  transactions for the Portfolio subject to
receipt of best execution. When selecting broker-dealers,  Keystone may consider
as a factor the number of shares of the Portfolio  sold by such  broker-dealers.
In addition,  broker-dealers  executing Portfolio transactions may, from time to
time, be affiliated with the Fund, Keystone,  Fiduciary Investment Company, Inc.
("FICO"), the Fund's principal underwriter ("Principal  Underwriter"),  or their
affiliates.  FICO, a  wholly-owned  subsidiary  of  Keystone,  is located at 200
Berkeley Street, Boston, Massachusetts 02116-5034.

  Subject to the  requirement  of receipt  of best  execution,  the Fund may pay
higher commissions to broker-dealers  that provide research  services.  Keystone
may use these  services  in advising  the Fund as well as in advising  its other
clients.

  The   Glass-Steagall   Act  presently  limits  the  ability  of  a  depository
institution  (such as a commercial  bank or a savings and loan  association)  to
become an underwriter  or  distributor  of  securities.  In the event the Glass-
Steagall  Act is deemed  to  prohibit  depository  institutions  from  accepting
payments in connection  with the sale of  securities,  or should  Congress relax
current  restrictions  on  depository  institutions,  the Board of Trustees will
consider what action, if any, is appropriate.

  In  addition,  state  securities  laws on  this  issue  may  differ  from  the
interpretations   of  federal  law   expressed   herein;   banks  and  financial
institutions  may be  required  to  register  as dealers  pursuant to state law.

PORTFOLIO TURNOVER

  The Fund  will not trade in  securities  for  short-term  profits,  but,  when
circumstances  warrant,  securities  may be sold without regard to the length of
time held.

- ------------------------------------------------------------------------------
HOW TO BUY SHARES
- ------------------------------------------------------------------------------

  Money Market Portfolio I is available to any investor making a minimum initial
purchase aggregating $250,000.

  There is no minimum amount required for subsequent purchases.

  Shares of the Portfolio are sold without a sales charge at the net asset value
per share,  normally  $1.00,  on each day on which  banks in both Boston and New
York City are open for business.  The Fund and its Principal Underwriter reserve
the right o reject any order for the purchase of Fund shares.


OPENING AN ACCOUNT
  First,  telephone Keystone Investor Resource Center, Inc. ("KIRC"), the Fund's
transfer and dividend  disbursing  agent, toll free at 1-800-343-2898 to open an
account and to obtain an account or wire identification number.

  Second,  arrange with your bank to wire  federal  funds to KIRC's agent at the
following address (please include your account number):

  State Street Bank and Trust Company
  For credit to MRT
  Account or wire identification
    number -------------------------------------------------------------------

  Third, complete and sign the Account Application and mail it to:

  Keystone Investor Resource Center, Inc.
  P.O. Box 2121
  Boston, Massachusetts 02106-2121

  If KIRC deems it  appropriate,  additional  documentation  or  verification of
authority may be required.

  Information  on how to wire federal funds is available at any national bank or
any state  bank that is a member of the  Federal  Reserve  System.  The bank may
charge for these  services.  Presently,  there is no fee for  receipt by KIRC of
federal funds wired, but the right to charge for this service is reserved.

  Additional  purchases  for an existing  account may be made by wiring  federal
funds,  or other funds  available to the Fund that day, to State Street Bank and
Trust Company as described above.

- ------------------------------------------------------------------------------
HOW TO REDEEM SHARES
- ------------------------------------------------------------------------------

  Shareholders may redeem shares of the Fund at net asset value,  normally $1.00
per share, by mail or by using the telephone.

MAIL REDEMPTIONS
  A  shareholder  may redeem shares on each day on which the Exchange is open by
mailing a written request to KIRC at the following address:

  Keystone Investor Resource Center, Inc.
  P.O. Box 2121
  Boston, Massachusetts 02106-2121

  The signatures on the written request must be PROPERLY GUARANTEED by a bank or
other persons eligible to guarantee signatures under the Securities Exchange Act
of 1934 and KIRC policies when the  circumstances of such  redemptions  indicate
that guaranteed signatures are appropriate, in the judgment of the Fund or KIRC,
for the protection of the Fund, its shareholders and KIRC.

TELEPHONE REDEMPTIONS
  A shareholder  may redeem shares on each day on which banks in both Boston and
New York City are open for business by calling  (toll free  1-800-343-2138).  To
engage in telephone  transactions  generally,  you must complete the appropriate
sections of the Fund's application.

  In order to insure that  instructions  received  by KIRC are genuine  when you
initiate a telephone  transaction,  you will be asked to verify certain criteria
specific to your  account.  At the  conclusion of the  transaction,  you will be
given a transaction number confirming your request,  and written confirmation of
your   transaction  will  be  mailed  the  next  business  day.  Your  telephone
instructions will be recorded.  Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.  If you  cannot  reach  the  Fund by  telephone,  you  should  follow  the
procedures for redeeming by mail as set forth above.

  The  proceeds of all  redemptions  will be wired in federal  funds only to the
commercial  bank (and  account  number)  designated  by the  shareholder  on the
Account  Application form.  CONSEQUENTLY,  SHAREHOLDERS MUST COMPLETE AN ACCOUNT
APPLICATION,   INCLUDING  THE  REDEMPTION   AUTHORIZATION.   If  KIRC  deems  it
appropriate,  additional documentation may be required.  Although at present the
Fund pays the wire costs involved,  it reserves the right at any time to require
the shareholder to pay such costs.

  Under normal circumstances, if the request for redemption is received by 12:00
Noon (eastern time) on a day on which banks in both Boston and New York City are
open for  business,  the proceeds of such  redemption  will be wired on the same
day, but the shareholder will not receive that day's dividend. If the request is
received  after 12:00 Noon or on a day when such banks are not open,  that day's
dividend will be received,  and the  redemption  proceeds will be wired the next
bank  business  day.  In order to permit the most  effective  management  of its
investments,  however, the Fund strongly urges shareholders  intending to redeem
amounts  over  $1,000,000  to notify the Fund at least one day in advance of the
redemption.  The  Fund  reserves  the  right  to take up to  seven  days to wire
redemption proceeds if, in the judgment of management,  the number and amount of
redemption requests received on any day prior to 12:00 Noon is unusual or if the
Fund could otherwise be adversely affected by making any payment.

  Payment  will be made  promptly  and, in any event,  within seven days after a
properly completed redemption request is received,  subject to suspension of the
right of  redemption  or extension of the date for payment when (1) the Exchange
is closed, other than customary weekend and holiday closings; (2) trading on the
Exchange is restricted;  (3) an emergency  exists and the Fund cannot dispose of
its  investments  or fairly  determine  their value;  or (4) the  Securities and
Exchange Commission so orders.

  Any change in the bank account designated to receive redemption  proceeds must
be  made  in  another  Account  Application  signed  by  the  shareholder  (WITH
SIGNATURES  PROPERLY  GUARANTEED IN THE MANNER DESCRIBED ABOVE) and delivered to
KIRC at the above address.

  The Fund reserves the right, at any time, to terminate,  suspend or change the
terms of any redemption  method described in this prospectus,  except redemption
by mail, and to impose fees.

  Except  as  otherwise   noted,   neither  the  Fund,  KIRC  nor  FICO  assumes
responsibility for the authenticity of any instructions  received by any of them
from a  shareholder  in writing or by  telephone.  KIRC will  employ  reasonable
procedures to confirm that instructions received over the telephone are genuine.
Neither  the  Fund,  KIRC nor FICO will be liable  when  following  instructions
received by telephone that KIRC reasonably  believes to be genuine.

  If a shareholder  redeems all the shares in an account,  the shareholder  will
receive, in addition to the value thereof, all declared but unpaid distributions
thereon.

  The Fund has made no  arrangements  with brokers for the repurchase of shares.
Redemptions  placed through  brokers,  who may charge for their  services,  must
comply with the redemption procedures and requirements described above.


SMALL ACCOUNTS

  The Fund reserves the right to redeem shares in any account in which the value
of shares of the  Portfolio  is less than such  minimum  amount as the  Trustees
prescribe.  Such redemption  proceeds will be promptly paid to the  shareholder.
Shareholders will be notified if their accounts are less than the minimum amount
and  given  30 days  to  bring  the  account  up to the  minimum  amount  before
redemption.

- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------

  Details on all shareholder  services may be obtained from KIRC by calling toll
free 1-800-343-2138 or from FICO by writing FICO at 200 Berkeley Street, Boston,
Massachusetts 02116-5034.

KEYSTONE AUTOMATED RESPONSE LINE
  The Keystone  Automated  Response Line ("KARL") offers  shareholders  specific
fund account  information;  price,  total return and yield  quotations;  and the
ability to effect account  transactions,  including  investments,  exchanges and
redemptions. Shareholders may access KARL by dialing toll free 1-800-346-3858 on
any  touch-tone  telephone,  24  hours a day,  seven  days a  week.

SHAREHOLDER ACCOUNTS
  Each investor will  automatically  have  established an account under which he
will receive a statement  showing  details of all  transactions,  including  the
current balance of full and fractional shares owned by such investor.
Certificates will not be issued.


SUBACCOUNTS
  Special   processing   has  been  arranged  with  KIRC  for  banks  and  other
institutions  that  wish  to  open  multiple  accounts  (a  master  account  and
subaccounts).  An  investor  wishing to avail  himself  of KIRC's  subaccounting
facilities will be required to enter into a separate agreement, with the charges
to be  determined  on the  basis of the level of  services  to be  rendered.  An
investor may open a subaccount  with his initial  investment  or at a later date
and may register the subaccount either by name or by number.

- ------------------------------------------------------------------------------
PERFORMANCE DATA
- ------------------------------------------------------------------------------

  From time to time, the Fund may advertise "yield" and "effective  yield." BOTH
YIELD FIGURES ARE BASED ON HISTORICAL  EARNINGS AND ARE NOT INTENDED TO INDICATE
FUTURE PERFORMANCE.  The "yield" of the Portfolio refers to the income generated
by an investment in the Portfolio over a seven-day  period (which period will be
stated in the advertisement). This income is then "annualized," i.e., the amount
of  income  generated  by the  investment  during  that  week is  assumed  to be
generated  each week over a 52-week  period and is shown as a percentage  of the
investment. The "effective yield" is calculated similarly, but, when annualized,
the income earned by an investment in the Portfolio is assumed to be reinvested.
The "effective  yield" will be slightly  higher than the "yield"  because of the
compounding effect of this assumed reinvestment.


  The Fund may also include comparative  performance  information in advertising
or marketing the Fund's shares,  such as data from Lipper  Analytical  Services,
Inc.,  Morningstar,  Inc.,  CDA-Weisenberger  and Value  Line or other  industry
publications.

  Any given  yield  quotation  should not be  considered  representative  of the
Portfolio's yield for any future period.

- ------------------------------------------------------------------------------
FUND SHARES
- ------------------------------------------------------------------------------

  The Fund may issue an unlimited  number of shares of the Portfolio.  Shares of
the Portfolio  participate equally in dividends and distributions and have equal
voting,  liquidation and other rights. When issued and paid for, the shares will
be  fully  paid  and  nonassessable  by the  Fund.  Shares  have no  preference,
conversion,  exchange or preemptive rights. Shares are redeemable,  transferable
and freely assignable as collateral. There are no sinking fund provisions.

  Shareholders are entitled to one vote for each full share owned and fractional
votes  for  fractional  shares.  Shares of the Fund vote  together  except  when
required by law to vote  separately by portfolio.  The Fund does not have annual
meetings.  The Fund will have special  meetings,  from time to time, as required
under its Declaration of Trust and under the 1940 Act. As provided in the Fund's
Declaration  of Trust,  shareholders  have the right to  remove  Trustees  by an
affirmative  vote of two-thirds of the outstanding  shares. A special meeting of
the  shareholders  will be held  when 10% of the  outstanding  shares  request a
meeting for the  purpose of  removing a Trustee.  The Fund is prepared to assist
shareholders  in  communications  with one another for the purpose of  convening
such meeting as prescribed by Section 16(c) of the 1940 Act.


  Under  Massachusetts  law, it is possible that a Fund  shareholder may be held
personally liable for the Fund's  obligations.  The Fund's  Declaration of Trust
provides,  however,  that  shareholders  shall not be  subject  to any  personal
liability  for the Fund's  obligations  and provides  indemnification  from Fund
assets for any shareholder  held personally  liable for the Fund's  obligations.
Disclaimers of such liability are included in each Fund agreement.

OBLIGATIONS OF FOREIGN BRANCHES OF UNITED STATES BANKS ("EURODOLLAR CERTIFICATES
OF DEPOSIT")

  The obligations of foreign  branches of U.S. banks may be general  obligations
of the parent bank in addition to the issuing  branch,  or may be limited by the
terms of a specific obligation and by government regulation. Payment of interest
and principal upon these obligations may also be affected by governmental action
in the  country of domicile of the branch  (generally  referred to as  sovereign
risk).  In addition,  evidences of  ownership  of such  obligations  may be held
outside  of the U.S.  and the Fund may,  consequently,  be  subject to the risks
associated with the holding of such property overseas.  Examples of governmental
actions would be the  imposition  of currency  controls,  interest  limitations,
withholding taxes, seizure of assets or the declaration of a moratorium. Various
provisions  of federal law governing  domestic  branches do not apply to foreign
branches of domestic  banks.

OBLIGATIONS OF U.S. BRANCHES OF FOREIGN BANKS ("YANKEE CERTIFICATES OF DEPOSIT")

  Obligations of U.S. branches of foreign banks may be general obligations of
the parent bank in addition to the issuing branch, or may be limited by the
terms of a specific obligation and by federal and state regulation as well as
by governmental action in the country in which the foreign bank has its head
office. In addition, there may be less publicly available information about a
U.S. branch of a foreign bank than about a domestic bank.

MASTER DEMAND NOTES


  Master demand notes are unsecured  obligations  that permit the  investment of
fluctuating  amounts by the Portfolio at varying  rates of interest  pursuant to
direct arrangements between the Portfolio as lender, and the issuer as borrower.
The  Portfolio  has the right to increase the amount under a note at any time up
to the full amount  provided by the note  agreement,  or to decrease the amount,
and the borrower  may repay up to the full amount of the note  without  penalty.
Notes  purchased by the Portfolio  permit it to demand  payment of principal and
accrued  interest  at any time (on not more  than  seven  days'  notice).  Notes
acquired by the  Portfolio may have  maturities of more than one year,  provided
(1) the Portfolio is entitled to payment of principal and accrued  interest upon
not more than seven days' notice,  and (2) the rate of interest on such notes is
adjusted automatically at periodic intervals,  which normally will not exceed 31
days, but may extend up to one year. The notes will be deemed to have a maturity
equal to the longer of the period remaining to the next interest rate adjustment
or the demand notice  period.  Because  these types of notes are direct  lending
arrangements  between  the lender and the  borrower,  such  instruments  are not
normally traded, and there is no secondary market for these notes, although they
are  redeemable  and thus  repayable  by the borrower at face value plus accrued
interest  at any  time.  Accordingly,  the right of the  Portfolio  to redeem is
dependent  on the  ability of the  borrower  to pay  principal  and  interest on
demand.  In  connection  with master  demand notes,  Keystone  considers,  under
standards  established by the Board of Trustees,  earning  power,  cash flow and
other  liquidity  ratios of the  borrower  and will  monitor  the ability of the
borrower to pay principal and interest on demand.  These notes are not typically
rated by credit rating agencies. Unless rated, the Portfolio will invest in them
only  if the  issuer  meets  the  criteria  established  for  commercial  paper.


CERTIFICATES OF DEPOSIT

  Certificates of deposit are receipts issued by a domestic or foreign bank or a
savings and loan  association  in exchange for the deposit of funds.  The issuer
agrees to pay the amount deposited plus interest to the bearer of the receipt on
the date specified on the certificate.  The certificate usually can be traded in
the secondary market prior to maturity.

  Certificates   of  deposit   will  be   limited  to  U.S.   dollar-denominated
certificates of domestic or foreign banks and/or a savings and loan  association
provided  that (1) at the  time of  investment  the  depository  institution  or
guarantor  bank has at least $1 billion in deposits  (as of the date of its most
recently  published  financial  statements)  or (2) the principal  amount of the
instrument  is  insured in full by the  Federal  Deposit  Insurance  Corporation
("FDIC").

  The  Fund  will  not  acquire  time  deposits  or  obligations  issued  by the
International  Bank for  Reconstruction  and Development;  the Asian Development
Bank or the  Inter-American  Development  Bank. See also "Obligations of Foreign
Branches of United States Banks,"  "Obligations  of Foreign  Branches of Foreign
Banks," and "Obligations of U.S. Branches of Foreign Banks."


BANKERS' ACCEPTANCES
  Bankers'  acceptances  typically  arise from  short-term  credit  arrangements
designed  to  enable   businesses   to  obtain   funds  to  finance   commercial
transactions.  Generally,  an  acceptance  is a time draft drawn on a bank by an
exporter or an importer to obtain a stated  amount of funds to pay for  specific
merchandise.  The  draft  is  then  "accepted"  by the  bank  that,  in  effect,
unconditionally  guarantees  to pay the  face  value  of the  instrument  on its
maturity  date.  The  acceptance  may then be held by the  accepting  bank as an
earning  asset or it may be sold in the  secondary  market at the going  rate of
discount for a specific maturity.  Although maturities for acceptances can be as
long as 270  days,  most  acceptances  have  maturities  of six  months or less.
Bankers'  acceptances  acquired  by the  Portfolio  must have been  accepted  by
domestic or foreign commercial banks or savings and loan associations and (1) at
the time of investment the depository institution or guarantor bank has at least
$1  billion  in  deposits  (as of the  date of  their  most  recently  published
financial  statements) or (2) the principal  amount of the instrument is insured
in full by the FDIC.

 LOAN PARTICIPATION NOTES
  A loan  participation  note represents  participation in a corporate loan of a
commercial  bank with a remaining  maturity of one year or less. Such loans must
be  to  corporations  in  whose  obligations  the  Portfolio  may  invest.   Any
participation  purchased by the  Portfolio  must be issued by a bank in the U.S.
with assets exceeding $1 billion.  Since the issuing bank does not guarantee the
participations  in any way,  they are  subject  to the  credit  risks  generally
associated with the underlying corporate borrower.  In addition,  because it may
be  necessary  under the terms of the loan  participation  for the  Portfolio to
assert  through the issuing bank such rights as may exist  against the corporate
borrower,  in the event the underlying corporate borrower fails to pay principal
and interest  when due,  the  Portfolio  may be subject to delays,  expenses and
risks that are greater than those that would have been involved if the Portfolio
had purchased a direct  obligation (such as commercial  paper) of such borrower.
Moreover,  under  the  terms  of the loan  participation  the  Portfolio  may be
regarded as a creditor of the issuing bank (rather than the underlying corporate
borrower),  so that the  Portfolio  may  also be  subject  to the risk  that the
issuing  bank may become  insolvent.  The  secondary  market,  if any,  for loan
participations is extremely limited and any such participations purchased by the
Portfolio may be regarded as illiquid.

REPURCHASE AGREEMENTS
  To earn additional income, the Portfolio may enter into repurchase  agreements
with member banks of the Federal Reserve System that have at least $1 billion in
assets,  primary  dealers  in U.S.  government  securities  or  other  financial
institutions believed by Keystone to be creditworthy.  Such persons are required
to be registered as U.S.  government  securities dealers with the Securities and
Exchange Commission and/or the regulatory organization routinely responsible for
their  regulation.  Under such  agreements,  the bank,  primary  dealer or other
financial  institution  agrees to repurchase  the security at a mutually  agreed
upon  time and  price,  thereby  determining  the yield  during  the term of the
agreement.  This  results  in a  fixed  rate of  return  insulated  from  market
fluctuations during such period. Under a repurchase  agreement,  the seller must
maintain the value of the  securities  subject to the agreement at not less than
the repurchase  price,  and such value is determined on a daily basis by marking
the  underlying  securities  to their market  values.  Although  the  securities
subject to the repurchase  agreement might bear maturities exceeding a year, the
Portfolio  only  intends to enter into  repurchase  agreements  that provide for
settlement  within a year and usually within seven days.  Securities  subject to
repurchase  agreements  will be held by the Fund's  custodian  or in the Federal
Reserve book entry system.  The Portfolio does not bear the risk of a decline in
the value of the  underlying  security  unless  the  seller  defaults  under its
repurchase obligation. In the event of a bankruptcy or other default of a seller
of a  repurchase  agreement,  the  Portfolio  could  experience  both  delays in
liquidating the underlying securities and losses including (1) possible declines
in the value of the underlying  securities during the period while the Portfolio
seeks to enforce its rights thereto; (2) possible subnormal levels of income and
lack of access to income  during this period;  and (3) expenses of enforcing its
rights. The Board of Trustees of the Fund has established procedures to evaluate
the  creditworthiness  of  each  party  with  whom  the  Portfolio  enters  into
repurchase agreements by setting guidelines and standards of review for Keystone
and monitoring Keystone's actions with regard to repurchase agreements.

LOANS OF SECURITIES TO BROKER-DEALERS
  To earn  additional  income,  the Portfolio may lend securities to brokers and
dealers pursuant to agreements  requiring that the loans be continuously secured
by cash or securities of the U.S. government, its agencies or instrumentalities,
or any combination of cash and such securities, as collateral equal at all times
in value to at least the market value of the securities loaned.  Such securities
loans  will not be made with  respect  to the  Portfolio  if,  as a result,  the
aggregate of all  outstanding  securities  loans exceeds 15% of the value of the
Portfolio's  total assets taken at their current value. The Portfolio  continues
to receive  interest or dividends on the  securities  loaned and  simultaneously
earns  interest on the investment of the cash loan  collateral in U.S.  Treasury
notes,  certificates  of deposit,  other high grade,  short term  obligations or
interest  bearing  cash   equivalents.   Although  voting  rights  attendant  to
securities loaned pass to the borrower, such loans may be called at any time and
will be called so that the  securities  may be voted by the Portfolio if, in the
opinion of the Fund, a material  event  affecting  the  investment  is to occur.
There may be risks of delay in receiving additional  collateral or in recovering
the  securities  loaned  or even loss of rights  in the  collateral  should  the
borrower of the securities fail financially. Loans may only be made, however, to
borrowers deemed to be of good standing,  under standards  approved by the Board
of Trustees,  when the income to be earned from the loan justifies the attendant
risks.

                          FUND OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------


         The Fund's investment objective is to provide shareholders with maximum
current  income  while  preserving  capital.  To meet this  objective,  the Fund
currently offers only one portfolio, Money Market Portfolio I (the "Portfolio").
This statement of additional  information provides information about and relates
solely to the Fund and the Portfolio.  Keystone  Investment  Management  Company
(formerly  Keystone  Custodian Funds,  Inc.)  ("Keystone")  serves as the Fund's
investment adviser.

         Subject  to the  availability  of master  notes  and to the  conditions
described in the next  sentence,  it is the Fund's  present  intention  that any
investments  the Portfolio may make in  instruments  maturing in one day or less
shall be made in master notes payable on demand.  The  Portfolio  will invest in
demand master notes only at such times as the yields available on such notes, to
Keystone's  knowledge,  are comparable to or exceed the yields then available on
securities  (otherwise  appropriate  for  investment  by the  Portfolio) of like
maturity  issued or guaranteed by the United States  ("U.S.")  government or any
agency or instrumentality thereof.

         The Portfolio will be diversified among issuers.  The Fund's investment
restrictions  permit the Fund to  concentrate up to 100% of its assets in one or
more of the  following  industries:  finance  companies,  banks and bank holding
companies and utility  companies.  Notwithstanding  the freedom  reserved by the
Fund to so  concentrate  assets,  the Portfolio (if permitted by its  investment
policies) may concentrate its assets only in (1) securities issued or guaranteed
by the U.S. government,  its agencies or instrumentalities;  and (2) instruments
issued by a domestic bank (including (a) a foreign branch of a domestic bank for
which the investment risk  associated with the securities  issued by such branch
is the same as the investment risk associated with the securities  issued by its
domestic  parent and (b) a U.S.  branch of a foreign bank that is subject to the
same regulation as U.S.  banks).  If permitted by its investment  policies,  the
Portfolio  will invest in excess of 25% of its assets in domestic  banks only at
such times as (1) the yields then  available on such  securities,  to Keystone's
knowledge, exceed the yields then available on securities (otherwise appropriate
for investment by the Portfolio) issued or guaranteed by the U.S.  government or
any agency or instrumentality thereof; and (2) in the opinion of management, the
relative  return  from  such  investments,  compared  with  the  relative  risk,
marketability   and  quality  of  such  securities,   appears  to  warrant  such
concentration.

         The Fund  intends  to  manage  the  maturities  of  instruments  in the
Portfolio so that  reasonably  anticipated  liquidity needs can be met from then
available  cash  rather  than from the sale of  portfolio  instruments  prior to
maturity.

- --------------------------------------------------------------------------------
                            INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
         The investment restrictions set forth below are fundamental and may not
be changed without the vote of a majority,  as defined in the Investment Company
Act of 1940 (the "1940 Act"), of the Fund's outstanding shares. The Fund may not
do the following:

         (1)  purchase  securities  on  margin,  but the  Fund may  obtain  such
short-term  credits as may be necessary for the clearance of purchases and sales
of securities;

         (2) make short sales of securities or maintain a short position, unless
at all times when a short  position  is open,  the Fund owns an equal  amount of
such  securities  or  of  securities  which,  without  payment  of  any  further
consideration,  are convertible  into or exchangeable for securities of the same
issue as the securities sold short;

         (3) borrow money, except from banks as a temporary measure in an amount
not to exceed  one-third of its total assets to  facilitate  redemptions  or for
extraordinary  or  emergency  purposes;  a loan  limitation  in  excess of 5% is
generally  associated  with a  leveraged  fund,  but since the Fund  anticipates
ordinarily  having to pay interest on borrowed money at rates  comparable to its
yield,  the Fund has no  intention of  attempting  to increase its net income by
borrowing,  and  any  such  borrowings  will be  repaid  before  any  additional
investments are made;

         (4) pledge assets except to secure indebtedness  permitted by the third
investment  restriction enumerated above, with pledged assets to be no more than
15% of its total assets;

         (5) purchase any security, other than U.S. government securities, if as
a result more than 25% of the Fund's  total assets would be invested in a single
industry,  except  that the Fund may  invest up to 100% of its assets in finance
companies  as a group,  banks and  bankholding  companies as a group and utility
companies as a group when, in the opinion of management, yield differentials and
money market conditions make such investments desirable and suitable investments
are available;

         (6) purchase any security,  other than U.S. government securities,  if,
as a result,  (a) more than 5% of the Fund's  total  assets would be invested in
securities of the issuer, or (b) the Fund would hold more than 10% of the voting
securities of the issuer;

         (7) invest for the purpose of exercising  control over or management of
any company;

         (8) invest in securities of other investment companies,  except as part
of a merger,  consolidation,  purchase of assets or similar transaction approved
by the Fund's shareholders;

         (9)  make  investments  in  commodities,  commodity  contracts  or real
estate; although the Fund has no present intention of doing so, it may invest in
securities  secured by real estate or interests  therein or issued by companies,
including real estate investment trusts,  which deal in real estate or interests
therein;

         (10) act as an underwriter or purchase  securities that are not readily
marketable, except for repurchase agreements;

         (11) purchase or retain securities of an issuer if, to the knowledge of
the  Fund,  an  officer,  Trustee  or  Director  of the  Fund or  Keystone  owns
beneficially  more than 1/2 of 1% of the shares or securities of such issuer and
all such  officers,  Trustees and  Directors  owning more than 1/2 of 1% of such
shares or securities together own more than 5% of such shares or securities;

         (12) purchase securities of any company that has, with predecessors,  a
record of less than three years' continuing operations, if as a result more than
5% of the total assets of the Fund would be invested in such securities;

         (13) purchase puts, calls, straddles,  spreads or combinations thereof,
except that in connection  with the purchase of  fixed-income  securities it may
acquire  warrants or other  rights to  subscribe  for  securities  of  companies
issuing such fixed-income securities or securities of parents or subsidiaries of
such companies,  although the fixed-income  securities would be purchased on the
basis of their  investment  characteristics  exclusive of such warrants or other
rights; and

         (14) invest in interests in oil, gas or other  mineral  exploration  or
development programs.


         Notwithstanding  the more flexible limits above, the Fund deems each of
its  fundamental  investment  restrictions  to apply to the  investments  of the
Portfolio.  For a clarification of how the  concentration  policies set forth in
the fifth investment restriction above specifically apply to the Portfolio,  see
"Fund Objective and Policies."

         With  respect to the  Portfolio,  the Fund has no present  intention of
investing more than 5% of the  Portfolio's  assets in short sales of securities,
securities  secured by real estate or interests  therein,  securities  issued by
companies that deal in real estate or interests therein, or warrants.

         The  Fund  may  make  loans,  but only  through  the  purchase  of debt
instruments  or repurchase  agreements  and through the lending of its portfolio
securities. The Fund has a policy that no portfolio will invest more than 10% of
its assets in illiquid securities,  including repurchase  agreements maturing in
more than seven days.


         The foregoing  percentages  will apply at the time of the purchase of a
security and shall not be  considered  violated  unless an excess or  deficiency
occurs  or  exists  immediately  after  and as a result  of a  purchase  of such
security.  In the event that any common  stock  should be  acquired  through the
exercise of  warrants,  it is  expected  that such stock would be sold as market
conditions permit in the exercise of prudent investment judgment.


         The Fund  understands  that the securities  laws of one state would not
permit the Fund to sell the Portfolio's shares in that state if it should pledge
in  excess  of 10% of the  Portfolio's  net  assets.  The  Fund  has no  present
intention of exceeding this limit,  although this limit is more restrictive than
the fourth investment restriction enumerated above.


- --------------------------------------------------------------------------------
                     VALUATION AND REDEMPTION OF SECURITIES
- --------------------------------------------------------------------------------
         Current  value for the Fund's  portfolio  securities  is  determined as
follows:  securities  purchased with maturities of sixty days or less are valued
at  amortized  cost  (original  purchase  cost as adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates  market;  securities  maturing  in more than  sixty  days for which
market  quotations are readily available are valued at current market value; and
securities  maturing in more than sixty days when purchased that are held on the
sixtieth day prior to maturity are valued at amortized cost (market value on the
sixtieth  day adjusted for  amortization  of premium or accretion of  discount),
which,  when combined with accrued  interest,  approximates  market, in any case
reflecting fair value as determined by the Board of Trustees. Any securities for
which market  quotations are not readily available or other assets are valued on
a  consistent  basis at fair value as  determined  in good faith  using  methods
prescribed by the Board of Trustees.


         The Fund  computes  the net  asset  value  per  share of the  Portfolio
rounded to the nearest one cent on a net asset value of $1.00. Accordingly,  the
net asset value will not reflect net realized or  unrealized  gains or losses on
portfolio  securities  that  amount to less than  one-half  cent per  share.  By
adhering to  restrictions  on the quality and  maturity of its  investments,  by
valuing certain securities at amortized cost, and by declaring all net income of
the Portfolio as a dividend  each time it is  determined,  the Fund  anticipates
that,  under  usual and  ordinary  circumstances,  it will be able to maintain a
constant net asset value,  so rounded,  of $1.00 per share for the Portfolio and
will use its best efforts to do so.

         The Fund has obligated itself under the 1940 Act to redeem for cash all
shares  presented for redemption by any one  shareholder in any 90 day period up
to the lesser of $250,000 or 1% of the Fund's  assets at the  beginning  of such
period.

- --------------------------------------------------------------------------------
                              DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------

         The net income of the Portfolio is determined as of the normal close of
trading on the New York Stock  Exchange (the  "Exchange")  (currently  4:00 p.m.
eastern  time) for purposes of pricing Fund shares on each business day on which
the Exchange is open.  All net income of the Portfolio so determined is declared
as a dividend to shareholders of record of the Portfolio as of that time.

         For this purpose, the net income of the Portfolio, from the time of the
immediately  preceding  determination  thereof,  shall  consist of all  interest
income accrued on the assets of the Portfolio, less all expenses and liabilities
of the  Portfolio  chargeable  against  income.  Interest  income shall  include
discount earned,  including both original issue and market discount, on discount
paper  accrued  ratably  to  the  date  of  maturity.  Expenses,  including  the
compensation payable to Keystone, are accrued each day.

         Any net realized  short-term capital gains of the Fund in excess of any
capital loss  carryover will be  distributed  to  shareholders  of the Portfolio
realizing  the  gain  from  time to  time as  management  deems  appropriate  in
maintaining the Portfolio's net asset value at $1.00 per share.

- --------------------------------------------------------------------------------
                                YIELD QUOTATIONS
- --------------------------------------------------------------------------------


         The current  yield of the  Portfolio as it may appear from time to time
in  advertisements,  is calculated by  determining  the net change  exclusive of
capital changes (all realized and unrealized gains and losses) in the value of a
hypothetical pre-existing account having a balance of one share at the beginning
of the period,  subtracting a hypothetical  charge  reflecting  deductions  from
shareholder accounts,  and dividing the net change in account value by the value
of the  account at the  beginning  of the base  period to obtain the base period
return,  multiplying  the base period return by 365/7 and carrying the resulting
current yield figure to the nearest hundredth of one percent.  The determination
of net change in account value reflects the value of additional shares purchased
with the dividends  from the original  share and dividends  declared on both the
original  share  and  any  such  additional  shares  and  all  fees  charged  to
shareholder  accounts  in  proportion  to the length of the base  period and the
Portfolio's average account size.

         In addition to the current yield,  the Portfolio's  effective yield may
appear from time to time in advertisements. The Portfolio's effective yield will
be calculated by compounding  the  unannualized  base period  return,  adding 1,
raising the sum to a power equal to 365 divided by 7, and subtracting 1 from the
result  and  carrying  the  resulting  effective  yield  figure  to the  nearest
hundredth of one percent.


         The current and effective  yields as quoted in any such  advertisements
will not be based on  information  as of a date more than fourteen days prior to
the  date  of  its  publication.  Each  yield  will  vary  depending  on  market
conditions,  and  principal  is not  insured.  Each  yield  also  depends on the
quality,  maturity and type of  instruments  held in the Portfolio and operating
expenses.  The advertisements  will include,  among other things, the length and
the date of the last day in the base period used in computing the quotation.

         The Fund does not currently  advertise or intend to advertise any yield
figures.

         During the fiscal year ended  December 31, 1994,  no Trustee or officer
received any direct remuneration from the Fund. During this same year, the Fund,
in aggregate,  paid or accrued $8,796 in retainers and fees to its nonaffiliated
Trustees for their  services to the Portfolio  and other  portfolios of the Fund
that have since become  inactive.  For the year ending  December 31, 1994,  fees
paid to  Independent  Trustees on a fund complex  wide basis were  approximately
$585,990.  As of March 31, 1995, the Fund's  Trustees and officers,  as a group,
beneficially owned less than one percent of the Fund's outstanding shares.

         The address of all the Fund's  Trustees  and  officers is 200  Berkeley
Street, Boston, Massachusetts 02116-5034.


- --------------------------------------------------------------------------------
                              DECLARATION OF TRUST
- --------------------------------------------------------------------------------
         The  Fund  is  a  Massachusetts  business  trust  established  under  a
Declaration of Trust dated  September 22, 1975, as amended and restated July 27,
1993  ("Declaration  of  Trust").  The Fund is  similar  in most  respects  to a
business  corporation.   The  principal  distinction  between  the  Fund  and  a
corporation relates to the shareholder  liability described below. A copy of the
Declaration  of  Trust  was  filed  as an  exhibit  to the  Fund's  Registration
Statement.  This summary is qualified in its entirety by reference to the Fund's
Declaration of Trust.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of beneficial  interest of one or more series and classes.  Each share
of a series or class represents an equal proportionate  interest with each other
share of the series or class. Upon liquidation shares are entitled to a pro rata
share in the net assets of the  portfolio of securities  underlying  the series.
Shareholders have no preemptive or conversion  rights.  Shares are transferable,
redeemable  and  fully  assignable  as  collateral.  There are no  sinking  fund
provisions.

SHAREHOLDER LIABILITY

         Pursuant to court decisions or other theories of law, shareholders of a
Massachusetts business trust may be held personally liable on the obligations of
the Fund. The  possibility of shareholders  incurring  financial loss under such
circumstances  appears  remote  because  the  Fund's  Declaration  of Trust  (1)
contains an express  disclaimer of shareholder  liability for obligations of the
Fund;  (2) requires that notice of such  disclaimer be given in each  agreement,
obligation or  instrument  entered into or executed by the Fund or the Trustees;
and  (3)  provides  for  indemnification  out  of  the  Fund  property  for  any
shareholder held personally liable for the obligations of the Fund.


VOTING RIGHTS

         Under the Declaration of Trust, the Fund does not hold annual meetings.
Shares are  entitled,  however,  to vote at meetings  called for the election of
Trustees  or to  consider  other  matters.  No  amendment  may  be  made  to the
Declaration  of Trust  without  the  approval of the  shareholders  of the Fund.
Shares have non-cumulative  voting rights,  which means that the holders of more
than 50% of the shares voting for the election of Trustees can elect 100% of the
Trustees  to be elected at a meeting,  and,  in such  event,  the holders of the
remaining  percentage  of shares  voting will not be able to elect any Trustees.
Shares of all of the Fund's  portfolios  vote together  irrespective of class on
all matters  except (1) when the 1940 Act requires that shares shall be voted by
an individual  portfolio,  and (2) when the Trustees of the Fund have determined
that a matter  does not  affect any  interest  of one or more  portfolios,  only
holders of shares of the other portfolio(s) shall be entitled to vote thereon.

         The  Trustees  shall  continue  to  hold  office  indefinitely,  unless
otherwise required by law, and may appoint successor  Trustees.  Trustees may be
removed from office (1) at any time by two-thirds vote of the Trustees; (2) when
any Trustee becomes  mentally or physically  incapacitated;  or (3) at a special
meeting of  shareholders by a two-thirds  vote of the  outstanding  shares.  Any
Trustee may also  voluntarily  resign from office.

LIMITATION OF TRUSTEES' LIABILITY

         The  Declaration  of Trust provides that a Trustee shall be liable only
for his own willful  defaults.  If  reasonable  care has been  exercised  in the
selection of officers, agents, employees or investment advisers, a Trustee shall
not be liable  for any  neglect  or  wrongdoing  of any such  person;  provided,
however,  that  nothing  in the  Declaration  of Trust  shall  protect a Trustee
against any liability for his willful  misfeasance,  bad faith, gross negligence
or reckless disregard of his duties.

         The Trustees have absolute and  exclusive  control over the  management
and  disposition of all assets of the Fund and may perform such acts as in their
sole  judgment  and  discretion  are  necessary  and proper for  conducting  the
business and affairs of the Fund or promoting  the interests of the Fund and the
shareholders.

- --------------------------------------------------------------------------------
                               INVESTMENT ADVISER
- --------------------------------------------------------------------------------
         Subject to the general  supervision  of the Fund's  Board of  Trustees,
Keystone  serves as investment  adviser to the Fund and is  responsible  for the
overall management of the Fund's business and affairs.


         Keystone,  located  at  200  Berkeley  Street,  Boston,   Massachusetts
02116-5034,   has  provided  investment  advisory  and  management  services  to
investment  companies  and  private  accounts  since it was  organized  in 1932.
Keystone is a  wholly-owned  subsidiary  of Keystone  Investments,  200 Berkeley
Street, Boston, Massachusetts 02116-5034.

         Keystone  Investments is a corporation  predominantly  owned by current
and former members of management of Keystone and its  affiliates.  The shares of
Keystone Investments common stock beneficially owned by management are held in a
number of voting trusts, the trustees of which are George S. Bissell,  Albert H.
Elfner, III, Edward F. Godfrey, and Ralph J. Spuehler,  Jr. Keystone Investments
provides  accounting,   bookkeeping,  legal,  personnel  and  general  corporate
services to Keystone  Management,  Keystone,  their  affiliates and the Keystone
Investments Family of Mutual Funds.

         Pursuant to its Investment  Advisory and Management  Agreement with the
Fund (the  "Advisory  Agreement")  and subject to the  supervision of the Fund's
Board of Trustees,  Keystone is required to provide all necessary administrative
services,  office  space,  equipment  and  clerical  personnel  for handling the
affairs of the  Portfolio.  The Advisory  Agreement  also  requires  Keystone to
furnish the Portfolio investment management services,  subject to the control of
the Trustees of the Fund; provided,  however,  that Keystone, at its own expense
may  contract  with one or more  firms to  provide  such  investment  management
services.  At the request and subject to the  direction  of the  Trustees of the
Fund,  Keystone  is also  required  to  provide or cause to be  provided  to the
Portfolio custodial, auditing, valuation, bookkeeping, legal, stock transfer and
dividend   disbursing   services;   services   related  to  and  preparation  of
shareholders' reports,  trustees' and shareholders' meetings; and maintenance of
registration  with the Securities and Exchange  Commission and various states as
well as  insurance  and  membership  in trade  associations  and related  items.
Keystone  pays all  charges  and  expenses  relating  to these  items as further
described  below.  Keystone  provides  certain of these items itself and obtains
others from other  organizations,  in each case subject to the  direction of the
Trustees.


         In addition to  Keystone's  compensation,  the Fund pays its  brokerage
commissions,  interest  charges,  taxes,  fees (other than the registration fees
referred to above) payable to government agencies,  any fees of its unaffiliated
Trustees for services to the Fund, and extraordinary expenses. Keystone pays the
compensation of any officers and affiliated Trustees of the Fund.


         As  compensation  for the services and facilities  provided to the Fund
pursuant to the Advisory Agreement, Keystone is generally entitled to receive at
the end of each fiscal  quarter an amount equal to (1) 5% of the gross income of
the  Portfolio,  less  (2) the  amount  of the net  expenses  borne  by the Fund
(excluding Keystone's compensation,  interest, taxes, brokerage commissions, and
extraordinary  expenses) for such  quarter;  but in no event shall the amount of
such  compensation  be less than  zero.  "Gross  income"  means the total of all
interest income calculated on an accrual basis and includes accrued discounts on
debt securities.

         Commencing December 28, 1992, Keystone, voluntarily limited its fee for
the Portfolio to an annual rate of 0.09% of the Portfolio's  average net assets.
Keystone  expects to maintain  this  voluntary  limitation  until the end of the
Fund's  fiscal year; at which time, a  determination  of whether to continue the
limitation and, if so, at what rate will be made.  Keystone continues to pay the
Fund's normal operating expenses,  excluding Keystone's compensation,  interest,
taxes,  brokerage  commissions,  fees of the Fund's  Independent  Trustees,  and
extraordinary expenses.

         The Advisory Agreement also provides that if the annual expenses of the
Fund exceed the limits on investment  company expenses imposed by any statute or
any  regulatory  authority of any  jurisdiction  in which shares of the Fund are
qualified  for offer and sale,  Keystone  will bear the amount of such excess to
the extent  required  thereunder.  Keystone  will not be  required  to bear such
excess, however, (1) to an extent greater than the compensation due Keystone for
the period for which such  expense  limitation  is  required  to be  calculated,
unless such  statute or  regulatory  authority  shall so require;  and (2) to an
extent  that would  result in the  Fund's  inability  to qualify as a  regulated
investment  company  under  provisions of the Internal  Revenue  Code.  The term
"expenses"  is  defined in such laws or  regulations  and,  generally  speaking,
excludes brokerage commissions,  taxes, interest and extraordinary  expenses. It
is  believed  that the lowest  such  annual  limitation,  as of the date of this
statement  of  additional  information,  was 2.5% of the  first  $30,000,000  of
average  month-end  net  assets,  2.0% of the next  $70,000,000  and 1.5% of any
excess over $100,000,000.

         For the fiscal years ended  December  31, 1992 and 1993,  the Fund paid
Keystone  $1,517,357  and  $510,844,  respectively,  for  investment  management
services.  For the year ended December 31, 1994, the Fund paid Keystone $148,293
for such services. Of such amount,  $49,118 was paid to Keystone for services to
Money  Market  Portfolio  I, which  represented  0.09% of its average  daily net
assets.


         Under the Advisory  Agreement,  any liability of Keystone in connection
with  rendering  services  thereunder  is limited to  situations  involving  its
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of its
obligations and duties.

         The  Advisory  Agreement  continues in effect from year to year only so
long as such continuance is specifically  approved at least annually by the vote
of a majority of the  Trustees who are not  "interested  persons" (as defined in
the 1940 Act) of the Fund or Keystone cast in person at a meeting called for the
purpose of voting on such  approval.  The Advisory  Agreement may be terminated,
without penalty, on 60 days' written notice by the vote of the Board of Trustees
or by the vote of a majority of the outstanding  voting  securities of the Fund.
Keystone may terminate the Advisory  Agreement on 90 days' written notice to the
Fund. The Advisory Agreement will terminate automatically upon its assignment.


         
- --------------------------------------------------------------------------------
                                  DISTRIBUTOR
- --------------------------------------------------------------------------------
         The Fund has entered into a Distribution  Agreement (the  "Distribution
Agreement") with FICO, a wholly-owned subsidiary of Keystone.


         The Fund has  appointed  FICO to act as  principal  underwriter  of the
Fund's shares in such states as the Fund may, from time to time, designate. FICO
will act as agent for the Fund and not as principal. FICO will have the right to
obtain  subscriptions  for and to sell  shares as agent of the Fund  and,  in so
doing,  may retain and employ  representatives  to promote  distribution  of the
shares  and may  obtain  orders  from  brokers or dealers or others for sales of
shares  to  them.  No such  representative,  dealer  or  broker  shall  have any
authority to act as agent for the Fund. The Distribution Agreement provides that
FICO will bear the expenses of preparing,  printing and distributing advertising
and sales literature and prospectuses used by it.

         All subscriptions and sales of shares by FICO are at the offering price
of the shares in accordance  with the  provisions of the Fund's  Declaration  of
Trust, By-Laws, current prospectus and statement of additional information.  All
orders are subject to acceptance by the Fund, and the Fund reserves the right in
its sole  discretion  to reject  any  order  received.  Under  the  Distribution
Agreement, the Fund is not liable to anyone for failure to accept any order.

         FICO has agreed that it will,  in all  respects,  duly conform with all
state and federal laws  applicable to the sale of the shares and will  indemnify
and hold harmless the Fund, and each person who has been, is or may be a Trustee
or officer of the Fund, against expenses  reasonably  incurred by any of them in
connection with any claim or in connection  with any action,  suit or proceeding
to which any of them may be a party,  that  arises out of or is alleged to arise
out of any misrepresentation or omission to state a material fact on the part of
FICO or any other person for whose acts FICO is  responsible or is alleged to be
responsible, unless such misrepresentation or omission was made in reliance upon
written information furnished by the Fund.

         The  Distribution  Agreement  continues in effect only if its terms and
its  continuance  are  approved at least  annually at a meeting  called for that
purpose by a majority of the Trustees  who are not parties to such  agreement or
"interested  persons"  of any such party and if its  continuance  is approved by
vote of a majority  of the  Trustees  or a majority  of the  outstanding  voting
shares of the Fund.  Under the Distribution  Agreement,  the Fund is responsible
for all  expenses in  connection  with the  registration  of its shares with the
Securities and Exchange Commission,  auditing and filing fees in connection with
the  registration of its shares under the various state  "blue-sky" laws and the
cost of  preparation  of  prospectuses  and other  expenses.  Keystone pays such
expenses on the Fund's behalf.

         The Distribution  Agreement may be terminated,  without penalty,  on 60
days'  written  notice by the Fund or on 90 days'  written  notice by FICO.  The
Distribution  Agreement will terminate  automatically  upon its  "assignment" as
that term is defined in the 1940 Act.

- --------------------------------------------------------------------------------
                                   BROKERAGE
- --------------------------------------------------------------------------------
         It is the policy of the Fund,  in effecting  transactions  in portfolio
securities,  to seek best execution of orders at the most favorable prices.  The
determination  of what may constitute  best execution and price in the execution
of a securities  transaction  by a broker  involves a number of  considerations,
including,  without  limitation,  the overall direct net economic  result to the
Fund,  involving both price paid or received and any commissions and other costs
paid, the  efficiency  with which the  transaction  is effected,  the ability to
effect the transaction at all where a large block is involved,  the availability
of the broker to stand ready to execute  potentially  difficult  transactions in
the  future  and the  financial  strength  and  stability  of the  broker.  Such
considerations   are  weighed  by   management   in   determining   the  overall
reasonableness of brokerage commissions paid.

          Subject to the foregoing,  a factor in the selection of brokers is the
receipt of research services,  such as analyses and reports concerning  issuers,
industries,  securities,  economic factors and trends and other  statistical and
factual  information.  Any such  research  and  other  statistical  and  factual
information  provided by brokers to the Fund or Keystone is  considered to be in
addition to and not in lieu of services  required  to be  performed  by Keystone
under the Advisory Agreement.  The cost, value and specific  application of such
information  are  indeterminable  and cannot be practicably  allocated among the
Fund  and  other  clients  of  Keystone  who may  indirectly  benefit  from  the
availability of such  information.  Similarly,  the Fund may indirectly  benefit
from  information  made  available  as a result of  transactions  for such other
clients.

         The Fund's securities transactions are generally principal transactions
with the issuer of the security or with major underwriters and dealers for money
market  instruments.  Accordingly,  the Fund does not pay significant  brokerage
commissions.  The cost of securities  purchased  from  underwriters  includes an
underwriting  commission or concession,  and the prices at which  securities are
purchased  from and sold to  dealers  include a dealer's  mark-up or  mark-down.
Purchases  from  underwriters  will  include  the  underwriting   commission  or
concession and purchases from dealers  serving as market makers will include the
spread  between the bid and asked  prices.  Where  transactions  are made in the
over-the-counter  market,  the Fund will deal with primary  market makers unless
more favorable prices are otherwise obtainable.

         The Fund may participate, if and when practicable, in group bidding for
the  purchase  directly  from an issuer of  certain  securities  for the  Fund's
portfolio in order to take advantage of the lower  purchase  price  available to
members of such a group.

         The  Board of  Trustees  of the Fund has  determined  that the Fund may
follow a policy of  considering  sales of shares as a factor in the selection of
broker-dealers to execute portfolio transactions, subject to the requirements of
best execution, including best price, described above.

         Investment  decisions for the Fund are made independently from those of
the other funds and investment  accounts managed by Keystone.  It may frequently
develop  that the same  investment  decision  is made  for more  than one  fund.
Simultaneous  transactions are inevitable when the same security is suitable for
the  investment  objective of more than one  account.  When two or more funds or
accounts  are  engaged  in the  purchase  or  sale  of the  same  security,  the
transactions  are  allocated as to amount in  accordance  with a formula that is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Fund is concerned.  In other cases,  however, it is believed that the
ability of the Fund to  participate in volume  transactions  will produce better
executions  for the Fund. It is the opinion of the Board of Trustees of the Fund
that the  desirability of retaining  Keystone as investment  adviser to the Fund
outweighs  any  disadvantages  that may result  from  exposure  to  simultaneous
transactions.

         The  policy  of the  Fund  with  respect  to  brokerage  is and will be
reviewed by the Board of Trustees from time to time.  Because of the possibility
of further  regulatory  developments  affecting  the  securities  exchanges  and
brokerage practices generally, the foregoing practices may be changed,  modified
or eliminated.

         In no  instance  are  portfolio  securities  purchased  from or sold to
Keystone,  FICO or any of their affiliated  persons,  as defined in the 1940 Act
and rules and regulations issued thereunder.


         During the fiscal years ended  December 31,  1992,  1993 and 1994,  the
Fund did not pay any brokerage commissions.

                            MONEY MARKET INSTRUMENTS

         The Fund's  investments in commercial  paper are limited to those rated
A-1 by  Standard & Poor's  Corporation  ("S&P"),  Prime-1  by Moody's  Investors
Service,   Inc.   ("Moody's")  or  F-1  by  Fitch's  Investors  Services,   Inc.
("Fitch's").  These  ratings and other money market  instruments  are  described
below.

COMMERCIAL PAPER RATINGS

         Commercial  paper rated A-1 by S&P has the  following  characteristics:
(1) liquidity  ratios are adequate to meet cash  requirements;  (2) the issuer's
long-term  senior  debt is rated "A" or better,  although  in some  cases  "BBB"
credits  may be  allowed;  (3) the issuer has access to at least two  additional
channels of  borrowing;  (4) basic  earnings  and cash flow have an upward trend
with allowance made for unusual circumstances;  and (5) typically,  the issuer's
industry is well  established,  and the issuer has a strong  position within the
industry.

         The rating Prime-1 is the highest  commercial  paper rating assigned by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type  risks that may be inherent in certain areas; (3) evaluation of
the issuer's  products in relation to competition and customer  acceptance;  (4)
liquidity;  (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten  years;  (7)  financial  strength  of a parent  company  and the
relationships  that exist with the issuer; and (8) recognition by the management
of  obligations  that  may be  present  or  may  arise  as a  result  of  public
preparations  to meet such  obligations.  Relative  strength  or weakness of the
above  factors  determines  how the  issuer's  commercial  paper is rated within
various categories.

         The rating F-1 is the highest  rating  assigned  by Fitch's.  Among the
factors  considered by Fitch's in assigning this rating are the  following:  (1)
the issuer's  liquidity;  (2) its standing in the industry;  (3) the size of its
debt; (4) its ability to service its debt; (5) its profitability; (6) its return
on equity;  (7) its  alternative  sources of  financing;  and (8) its ability to
access the capital  markets.  Analysis of the  relative  strength or weakness of
these  factors and others  determines  whether an issuer's  commercial  paper is
rated F-1.

MASTER DEMAND NOTES

         Master  demand  notes  are  unsecured   obligations   that  permit  the
investment  of  fluctuating  amounts  by the Fund at varying  rates of  interest
pursuant to direct arrangements  between the Fund, as lender, and the issuer, as
borrower. Master demand notes may permit daily fluctuations in the interest rate
and daily  changes in the amounts  borrowed.  The Fund has the right to increase
the amount under the note at any time up to the full amount provided by the note
agreement or to decrease  the amount under the note,  and the borrower may repay
up to the full amount of the note without  penalty.  Notes purchased by the Fund
must permit the Fund to demand payment of principal and accrued  interest at any
time (on not more than seven days'  notice) or to resell the note at any time to
a third party.  Master demand notes purchased by the Fund may have maturities of
more than one year,  provided  they  specify  that (1) the Fund be  entitled  to
payment of principal and accrued interest upon not more than seven days' notice,
and (2) the rate of interest on such notes be adjusted automatically at periodic
intervals  which normally will not exceed 31 days but may extend up to one year.
Because these types of notes are direct lending  arrangements between the lender
and  borrower,  such  instruments  are not  normally  traded,  and  there  is no
secondary  market  for  these  notes,  although  they  are  redeemable  and thus
repayable  by the  borrower  at face value plus  accrued  interest  at any time.
Accordingly,  the  Fund's  right to redeem is  dependent  on the  ability of the
borrower to pay  principal  and interest on demand.  In  connection  with master
demand note arrangements,  Keystone Investment  Management Company  ("Keystone")
considers,  under standards established by the Board of Trustees, earning power,
cash flow, and other liquidity  ratios of the borrower and continually  monitors
the  ability of the  borrower to pay  principal  and  interest on demand.  These
notes, as such, are not typically rated by credit rating  agencies.  Unless they
are so rated,  the Fund may invest in them only if at the time of an  investment
the issuer meets the criteria set forth above for  commercial  paper.  The notes
will be deemed to have a maturity equal to the longer of the period remaining to
the next interest rate adjustment or the demand notice period.

U.S. GOVERNMENT SECURITIES

         Securities  issued  or  guaranteed  by the U.S.  government  include  a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities and dates of issuance.  Treasury bills have maturities of one year or
less.  Treasury  notes have  maturities  of one to ten years and Treasury  bonds
generally have maturities of greater than ten years at the date of issuance.

         Securities issued or guaranteed by the U.S.  government or its agencies
or  instrumentalities  include  direct  obligations  of the  U.S.  Treasury  and
securities issued or guaranteed by the Federal Housing  Administration,  Farmers
Home  Administration,  Export-Import  Bank of the United States,  Small Business
Administration,  Government  National  Mortgage  Association,  General  Services
Administration,  Central Bank for Cooperatives, Federal Home Loan Banks, Federal
Loan Mortgage  Corporation,  Federal  Intermediate  Credit  Banks,  Federal Land
Banks,  Maritime  Administration,  The Tennessee Valley  Authority,  District of
Columbia Armory Board and Federal National Mortgage Association.

         Some  obligations of U.S.  government  agencies and  instrumentalities,
such as Treasury bills and Government National Mortgage Association pass-through
certificates, are supported by the full faith and credit of the U.S. government.
Others,  such as  securities  of Federal Home Loan Banks,  are  supported by the
right of the issuer to borrow from the  Treasury.  Still  others,  such as bonds
issued by the Federal National Mortgage Association, a private corporation,  are
supported only by the credit of the instrumentality. Because the U.S. government
is not obligated by law to provide  support to an  instrumentality  it sponsors,
the Fund will invest in the securities  issued by such an  instrumentality  only
when   Keystone   determines   that  the  credit   risk  with   respect  to  the
instrumentality  does not  make  its  securities  unsuitable  investments.  U.S.
government   securities   will   not   include    international    agencies   or
instrumentalities   in   which   the   U.S.   government,    its   agencies   or
instrumentalities participate, such as the International Bank for Reconstruction
and  Development  (the  "World  Bank"),   the  Asian  Development  Bank  or  the
Inter-American  Development  Bank,  or issues  insured  by the  Federal  Deposit
Insurance Corporation.

CERTIFICATES OF DEPOSITS

         Certificates  of deposit are receipts  issued by a bank in exchange for
the  deposit  of funds.  The  issuer  agrees to pay the  amount  deposited  plus
interest to the bearer of the receipt on the date specified on the  certificate.
The certificate usually can be traded in the secondary market prior to maturity.

         Certificates  of deposit  will be limited  to U.S.  dollar  denominated
certificates  of  U.S.  banks  (including  their  branches  abroad)  and of U.S.
branches of foreign banks that are members of the Federal  Reserve System or the
Federal Deposit Insurance Corporation,  and have at least $1 billion in deposits
as of the date of their most recently published financial statements.

         The Fund will not acquire time  deposits or  obligations  issued by the
World Bank, the Asian Development Bank or the  Inter-American  Development Bank.
Additionally,  the Fund does not  currently  intend  to  purchase  such  foreign
securities  (except  to the  extent  that  certificates  of  deposit  of foreign
branches  of  U.S.  banks  may  be  deemed   foreign   securities)  or  purchase
certificates  of deposit,  bankers'  acceptances  or other  similar  obligations
issued by foreign banks.

BANKERS' ACCEPTANCES

         Bankers'   acceptances   typically   arise   from   short-term   credit
arrangements designed to enable businesses to obtain funds to finance commercial
transactions.  Generally,  an  acceptance  is a time draft drawn on a bank by an
exporter or an importer to obtain a stated  amount of funds to pay for  specific
merchandise.  The  draft  is  then  "accepted"  by the  bank  that,  in  effect,
unconditionally  guarantees  to pay the  face  value  of the  instrument  on its
maturity  date.  The  acceptance  may then be held by the  accepting  bank as an
earning  asset or it may be sold in the  secondary  market at the going  rate of
discount for a specific maturity.  Although maturities for acceptances can be as
long as 270  days,  most  acceptances  have  maturities  of six  months or less.
Bankers'  acceptances  acquired  by the Fund  must have  been  accepted  by U.S.
commercial banks,  including foreign branches of U.S.  commercial banks,  having
total  deposits  at the time of  purchase  in excess of $1  billion  and must be
payable in U.S. dollars.

REPURCHASE AGREEMENTS

         The Fund may enter into repurchase  agreements.  Repurchase  agreements
may be entered into only with a member bank of the Federal  Reserve System which
has at  least  $1  billion  in  assets,  a  primary  dealer  in U.S.  government
securities  or  other   financial   institution   believed  by  Keystone  to  be
creditworthy.  At this time such  persons are not required to be  registered  as
U.S. government securities dealers with any regulatory organization.  Under such
agreements, the bank, primary dealer or other financial institution agrees, upon
entering into the contract, to repurchase the security at a mutually agreed upon
date and price,  thereby determining the yield during the term of the agreement.
This results in a fixed rate of return insulated from market fluctuations during
such  period.  The seller  under a  repurchase  agreement  will be  required  to
maintain the value of the  securities  subject to the agreement at not less than
the  repurchase  price,  and such value will be  determined  on a daily basis by
marking the underlying securities to their market value. Although the securities
subject to the repurchase  agreement might bear maturities exceeding a year, the
Fund  only  intends  to  enter  into  repurchase  agreements  that  provide  for
settlement  within a year and usually within seven days.  Securities  subject to
repurchase  agreements  will be held by the Fund's  custodian  or in the Federal
Reserve Book Entry System. The Fund does not bear the risk of a decline in value
of the  underlying  security  unless the seller  defaults  under its  repurchase
obligation.  In the  event of a  bankruptcy  or other  default  of a seller of a
repurchase  agreement,  the Fund could experience both delays in liquidating the
underlying  securities and losses,  including (1) possible declines in the value
of the underlying  securities  during the period while the Fund seeks to enforce
its rights thereto;  (2) possible  subnormal levels of income and lack of access
to income  during this period;  and (3) expenses of  enforcing  its rights.  The
Board of  Trustees  of the Fund  has  established  procedures  to  evaluate  the
creditworthiness  of each  party  with  whom the  Fund  enters  into  repurchase
agreements  by setting  guidelines  and  standards  of review for  Keystone  and
monitoring Keystone's actions with regard to repurchase agreements.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1994

         (1) SIGNIFICANT ACCOUNTING POLICIES
         Master Reserves Trust (the "Fund"), a Massachusetts  business trust, is
an  open-end  management  investment  company  registered  under the  Investment
Company Act of 1940. Keystone Management, Inc. ("KMI") is the Investment Manager
and Keystone  Custodian Funds,  Inc.  ("Keystone"),  is the Investment  Adviser.
Keystone  is a  wholly-owned  subsidiary  of Keystone  Group,  Inc.  ("KGI"),  a
Delaware corporation.  KGI is privately owned by an investor group consisting of
members of current  management of Keystone.  Keystone  Investor Resource Center,
Inc.  ("KIRC"),  a wholly-owned  subsidiary of Keystone,  is the Fund's transfer
agent.

   The Fund began offering shares of its existing  portfolio,  Money Market I on
May 4, 1976.

On May 27,1994,  all of the outstanding shares of the U.S. Treasury Money Market
Portfolio were  redeemed.  On July 29, 1994,  all of the  outstanding  shares of
Money  Market  Portfolio  XI were  redeemed.  On  August  16,  1994,  all of the
outstanding  shares of the Robert Van U.S.  Government  Securities  Money Market
Portfolio were redeemed.

         The  following  is  a  summary  of  significant   accounting   policies
consistently  followed by the Fund in preparation  of its financial  statements.
The policies are in conformity with generally accepted accounting principles.

         A. Portfolio  securities  which are purchased with  maturities of sixty
days or less are valued at amortized  cost  (original  purchase cost as adjusted
for amortization of premium or accretion of discount) which,  when combined with
accrued interest,  approximates  market.  Portfolio  securities maturing in more
than sixty days for which market  quotations are readily available are valued at
current market value. Portfolio securities maturing in more than sixty days when
purchased,  which are held on the sixtieth day prior to maturity,  are valued at
amortized  cost (market value on the sixtieth day adjusted for  amortization  of
premium or accretion  of discount)  which when  combined  with accrued  interest
approximates  market.  All other  securities and other assets are valued at fair
value as  determined  in good faith  using  methods  prescribed  by the Board of
Trustees.

         B.  Securities  transactions  are  accounted  for  on the  trade  date.
Interest income is recorded on the accrual basis. Realized gains and losses from
securities  transactions are determined using the identified cost basis for both
financial reporting and federal income tax purposes. Any net realized short-term
capital  gains of the Fund will be  distributed  from  time to time as  Keystone
deems appropriate to maintain a portfolio's net asset value at $1.00 per share.

         C. The Fund has qualified,  and intends to qualify in the future,  as a
regulated  investment company under the Internal Revenue Code of 1986 as amended
(Internal  Revenue  Code).  Thus,  the Fund (each  portfolio) is relieved of any
federal income tax liability by  distributing  all of its net investment  income
and net capital gains,  if any, to its  shareholders.  The Fund intends to avoid
excise tax  liability  by making the required  distributions  under the Internal
Revenue Code.

         D. When the Fund  enters  into a  repurchase  agreement  (a purchase of
securities  whereby the seller agrees to repurchase the securities at a mutually
agreed  upon  date  and  price)  the  repurchase  price of the  securities  will
generally equal the amount paid by the Fund plus a negotiated  interest  amount.
The seller under the repurchase agreement will be required to provide securities
("collateral")  to the Fund whose value will be maintained at an amount not less
than the repurchase price, and which generally will be maintained at 101% of the
repurchase  price.  The Fund  monitors the value of collateral on a daily basis,
and if the value of the collateral falls below required levels, the Fund intends
to seek  additional  collateral  from the  seller or  terminate  the  repurchase
agreement.  If the seller  defaults,  the Fund would suffer a loss to the extent
that the proceeds from the sale of the underlying  securities were less than the
repurchase  price.  Any such loss would be  increased  by any cost  incurred  on
disposing of such securities.  If bankruptcy  proceedings are commenced  against
the seller under the repurchase agreement, the realization on the collateral may
be delayed or limited.  Repurchase  agreements  entered into by the Fund will be
limited to  transactions  with  dealers or  domestic  banks  believed to present
minimal  credit  risks,  and the Fund  will  take  constructive  receipt  of all
securities underlying repurchase agreements until such agreements expire.
<PAGE>
         E. Each portfolio  declares dividends from net investment income daily,
pays dividends monthly and automatically  reinvests such dividends in additional
shares at net asset value, unless shareholders request payment in cash.

         F.  Unaffiliated  Trustees are paid an annual  retainer of $1,000 and a
meeting  attendance  fee of $30. Any  compensation  of officers  and  affiliated
Trustees of the Fund is paid by the Investment Manager.

         (2) MANAGEMENT FEES
         Under the terms of the current management  contract,  Keystone provides
investment  management  and  administrative  services  as well as office  space,
equipment  and clerical  personnel  for handling the affairs of the Fund. At the
request and subject to the  discretion of the Trustees of the Fund,  Keystone is
required  at its own  expense to provide or cause to be provided to the Fund the
following  additional  operating services,  facilities and supplies:  custodial,
auditing, valuation,  bookkeeping, legal, stock transfer and dividend disbursing
services,  shareholders'  reports, and shareholders' meetings and maintenance of
registration with the Securities and Exchange  Commission and various states, as
well as insurance and membership in trade  associations  and related  items.  In
return, Keystone is entitled to a fee, payable quarterly, computed at the annual
rate of 0.09% of average daily net assets of each  portfolio  except as follows:
Money  Market  Portfolio XI pays  quarterly 4% of gross income on an  annualized
basis; the Robert Van U.S. Government Securities Money Market Portfolio, accrues
an annual fee of 0.20% of average daily net assets, payable quarterly.

         During the year ended December 31, 1994, the Fund, in aggregate, paid a
management fee of $148,293 to Keystone.

         (3) SHARES OF BENEFICIAL INTEREST
         The Fund is authorized to issue an unlimited  number of shares,  no par
value,  for each  portfolio.  All capital  share  transactions  included in each
portfolio's  Statement  of Changes in Net Assets were made at net asset value of
$1.00 per share.

         (4) INVESTMENT TRANSACTIONS
         The  aggregate  cost of  purchases  and the  proceeds  from the sale of
investment  securities for the year ended December 31, 1994,  (except as noted),
were as follows:

                          INDEPENDENT AUDITORS' REPORT


The Trustees and Shareholders
Master Reserves Trust



We have audited the financial statements, including the schedule of investments,
and the financial  highlights  for the portfolios of Master  Reserves Trust (the
"Portfolios") as listed in the accompanying index to financial statements. These
financial  statements  and financial  highlights are the  responsibility  of the
Portfolios'  management.  Our  responsibility  is to express an opinion on these
financial statements and financial highlights based on our audits.


We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free from material misstatement.  An audit includes examining, on
a test basis,  evidence  supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1994 by correspondence  with the custodian.  An audit includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion,  the  financial  statements  and  financial  highlights  present
fairly, in all material  respects,  the financial  position of the portfolios of
Master Reserves Trust as of December 31, 1994, the results of their  operations,
the  changes  in their net  assets  and  financial  highlights  for the  periods
specified in the index to financial  statements  in  conformity  with  generally
accepted accounting principles.
