KEYSTONE INSTITUTIONAL
ADJUSTABLE RATE FUND
PROSPECTUS DECEMBER 10, 1996

  Keystone Institutional Adjustable Rate Fund (the "Fund") is a diversified,
open-end management investment company, commonly known as a mutual fund, that
seeks a high level of current income, consistent with low volatility of
principal, by investing under ordinary circumstances at least 65% of its assets
in adjustable rate securities. Such securities include adjustable rate mortgage
securities that are issued or guaranteed by the United States ("U.S.")
government, its agencies or instrumentalities. The Fund does not attempt to
maintain a constant price per share. The Fund does, however, follow a strategy
that seeks to minimize changes in its net asset value per share by investing
primarily in adjustable rate securities whose interest rates are periodically
reset when market rates change.

  The Fund is designed for institutional investors and seeks to provide a
relatively stable net asset value while providing high current income relative
to high-quality, short-term investment alternatives.

  The Fund offers Class Y and Z shares. Information on share classes and their
fee and sales charge structures may be found in the "Fee Table," "How to Buy
Shares," "Alternative Sales Options," "Distribution Plan" and "Fund Shares"
sections of this prospectus.

  This prospectus concisely states information about the Fund that you should
know before investing. Please read it and retain it for future reference.

  Additional information about the Fund is contained in a statement of
additional information dated December 10, 1996, which has been filed with the
Securities and Exchange Commission and is incorporated by reference into this
prospectus. For a free copy, or for other information about the Fund, write to
the address or call the telephone number provided on this page.

THE FUND
  The Fund was formed as a Massachusetts business trust on June 19, 1991. The
Fund is one of more than thirty funds advised by Keystone Investment Management
Company ("Keystone"), the Fund's investment adviser.

INVESTMENT OBJECTIVE AND POLICIES

INVESTMENT OBJECTIVE
  The Fund seeks a high level of current income consistent with low volatility
of principal. The investment objective of the Fund is fundamental and may not be
changed without approval of the holders of a majority (as defined in the
Investment Company Act of 1940 ("1940 Act") of the Fund's outstanding shares
(which means the lesser of (1) 67% of the shares represented at a meeting at
which more than 50% of the outstanding shares are represented or (2) more than
50% of the outstanding shares).

  Any investment involves risk, and there is no assurance that the Fund will
achieve its investment objective.

PERMITTED INVESTMENTS
   Under ordinary circumstances, the Fund invests at least 65% of its assets in
mortgage securities or other securities collateralized by or representing an
interest in a pool of mortgages (collectively, "Mortgage Securities"), which
securities have interest rates that reset at periodic intervals and are issued
or guaranteed by the U.S. government, its agencies or instrumentalities.

  The Fund does not attempt to maintain a constant price per share. However, the
Fund does follow a strategy that seeks to minimize changes in its net asset
value per share by investing primarily in adjustable rate securities, whose
interest rates are periodically reset when market rates change. The average
dollar weighted reset period of adjustable rate securities held by the Fund will
not exceed one year. The Fund seeks to provide a relatively stable net asset
value while providing high current income relative to high-quality, short-term
investment alternatives.

INVESTMENT POLICIES AND APPROACH
  Keystone believes that, by investing primarily in Mortgage Securities with
adjustable rates of interest, the Fund will achieve a less volatile net asset
value per share than is characteristic of mutual funds that invest primarily in
U.S. government securities paying a fixed rate of interest.
    

  Unlike fixed rate mortgages and loans that generally decline in value during
periods of rising interest rates, adjustable rate Mortgage Securities ("ARMS")
allow the Fund to participate in increases in interest rates through periodic
adjustments in the coupons of the underlying mortgages or loans, resulting in
both higher current yields and lower price fluctuations in the Fund's net asset
value per share. The Fund is also affected by decreases in interest rates
through periodic decreases in the coupons of the underlying mortgages or loans
resulting in lower income to the Fund. This downward adjustment results in lower
price fluctuations in the net asset value per share in a decreasing interest
rate environment. As the interest rates on the mortgages or loans underlying the
Fund's investments are reset periodically, coupons of portfolio securities will
gradually align themselves to reflect changes in market rates and should cause
the net asset value per share of the Fund to fluctuate less dramatically than it
would if the Fund invested in more traditional long-term, fixed rate mortgages.

  The portion of the Fund that is not invested in ARMS, if any, is intended to
increase the Fund's total return from changes in market rates while not
materially increasing the volatility of the net asset value per share.

  The Fund intends to follow the policies of the Securities and Exchange
Commission as they are adopted from time to time with respect to illiquid
securities, including, at this time, (1) treating as illiquid, securities that
may not be sold or disposed of in the ordinary course of business within seven
days at approximately the value at which the Fund has valued such securities on
its books and (2) limiting its holdings of such securities to 15% of net assets.

   
PERMITTED  INVESTMENTS
  The Fund invests in Mortgage Securities that are issued or guaranteed by the
U.S. government, one of its agencies or instrumentalities, such as the
Government National Mortgage Association ("GNMA"), the Federal National Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC").
Securities issued by GNMA, but not those issued by FNMA or FHLMC, are backed by
the full faith and credit of the U.S. government.

  The Fund invests in mortgage pass-through securities representing
participation interests in pools of residential mortgage loans originated by
U.S. governmental lenders and guaranteed, to the extent provided in such
securities, by the U.S. government, its agencies or instrumentalities. Such
securities, which are ownership interests in the underlying mortgage loans,
differ from conventional debt securities, which provide for periodic payment of
interest in fixed amounts (usually semiannually) and principal payments at
maturity or on specified call dates. Mortgage pass-through securities provide
for monthly payments that are a "pass-through" of the monthly interest and
principal payments (including any prepayments) made by the individual borrowers
on the pooled mortgage loans, net of any fees paid to the guarantor of such
securities and the servicer of the underlying mortgage loans.
    

  The guaranteed mortgage pass-through securities in which the Fund invests
include those issued or guaranteed by GNMA, FNMA and FHLMC. GNMA certificates
are direct obligations of the U.S. government and, as such, are backed by the
full faith and credit of the U.S. government. FNMA is a federally chartered,
privately owned corporation. FHLMC is a corporate instrumentality of the U.S.
government. FNMA and FHLMC certificates are not backed by the full faith and
credit of the U.S. government and are supported only by the credit of FNMA and
FHLMC, which have the right to borrow to meet their obligations from an
existing line of credit with the U.S. Treasury. Although their close
relationship with the U.S. government is believed to make them high quality
securities with minimal credit risks, the U.S. government is not obligated by
law to support either FNMA or FHLMC. Historically, however, there have been no
defaults in any FNMA or FHLMC issues.

  Certificates for Mortgage Securities evidence an interest in a specific pool
of mortgages. These certificates are, in most cases, "modified pass-through"
instruments, wherein the issuing agency guarantees the payment of principal and
interest on mortgages underlying the certificates, whether or not such amounts
are collected by the issuer on the underlying mortgages.

  Adjustable rate mortgages are an important form of residential financing.
Generally, adjustable rate mortgages are mortgages that have a specified
maturity date and amortize in a manner similar to that of a fixed rate mortgage.
As a result, in periods of declining interest rates there is a reasonable
likelihood that adjustable rate mortgages will behave like fixed rate mortgages
in that current levels of prepayments of principal on the underlying mortgages
could accelerate. However, one difference between adjustable rate mortgages and
fixed rate mortgages is that for certain types of adjustable rate mortgages the
rate of amortization of principal, as well as interest payments, can and does
change in accordance with movements in a particular, pre-specified, published
interest rate index. The amount of interest due a holder of an adjustable rate
mortgage is calculated by adding a specified additional amount (margin) to the
index, subject to limitations or "caps" on the maximum and minimum interest rate
that is charged to the mortgagor during the life of the mortgage or to maximum
and minimum changes in that interest rate during a given period. It is these
special characteristics, unique to the adjustable rate mortgages underlying the
ARMS in which the Fund invests, that are believed to make ARMS attractive
investments for seeking to accomplish the Fund's objective. For further
information, see "Prepayments" in the section on "Risk Factors."

   
OTHER PERMITTED INVESTMENTS
  The Fund may invest in collateralized mortgage obligations ("CMOs") issued
or guaranteed by the U.S. government, its agencies or instrumentalities. The
Fund intends to invest only in CMOs that, in Keystone's opinion, are suitable
in light of the Fund's investment objective and policies. For further
information, see "Additional Investment Information."
    

  In addition, the Fund may enter into repurchase agreements and reverse
repurchase agreements for eligible securities and U.S. government obligations.
For further information, see "Additional Investment Information."

  The Fund may also invest up to 35% of its assets under ordinary circumstances
and up to 100% of its assets for temporary defensive purposes in obligations of
the U.S. government, its agencies or instrumentalities, such as the Federal Home
Loan Banks, FNMA, GNMA, FHLMC or the Federal Farm Credit Banks.

  The Fund may assume a temporary defensive position, for example, upon
Keystone's determination that market conditions so warrant. The Fund may not be
pursuing its investment objective when it assumes a temporary defensive
position.

  The Fund will not invest in derivative Mortgage Securities other than the CMOs
described in "Additional Investment Information."

   
INVESTMENT RESTRICTIONS
  The Fund has adopted the fundamental restrictions summarized below, which may
not be changed without the approval of a 1940 Act majority of the Fund's
outstanding shares. These restrictions and certain other fundamental and
non-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 may not do the following: (1) with respect to 75% of its
total assets, invest more than 5% of the value of its total assets in the
securities of any one issuer; this limitation does not apply to investments in
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities; and (2) borrow money or enter into reverse repurchase
agreements, except that the Fund may (a) enter into reverse repurchase
agreements or (b) borrow money from banks for temporary or emergency purposes in
aggregate amounts of up to one-third of the value of the Fund's net assets;
provided that, while borrowings exceed 5% of the Fund's net assets, any such
borrowings will be repaid before additional investments are made.

RISK FACTORS
  Like any investment, your investment in the Fund involves an element of risk.
Before you buy shares of the Fund, you should carefully evaluate your ability to
assume the risks your investment in the Fund poses.

  By itself, the Fund does not constitute a balanced investment program.
Investors should take into account their investment objectives as well as other
investments when considering the purchase of shares of any investment company.

  Certain risks related to the Fund are discussed below. In addition to the
risks discussed in this section, specific risks attendant to individual
securities or investment practices are discussed in "Additional Investment
Information" and the statement of additional information.

  Should the Fund need to raise cash to meet a large number of redemptions the
Fund might have to sell portfolio securities at a time when it would be
disadvantageous to do so.

INTEREST RATE RISK
  The values of fixed-rate securities fluctuate in response to changes in
interest rates; generally rising when interest rates decline, and falling, when
interest rates rise. As a result, if interest rates increase after a security is
purchased, the security, if sold prior to maturity, may return less than its
cost. The corresponding increase or decrease in the value of fixed-rate
securities generally becomes more significant for instruments with longer
remaining maturities or longer expected remaining lives. Moreover, investment
yields on relatively short-term investments are subject to substantial and rapid
fluctuation.

PREPAYMENTS
  The Mortgage Securities in which the Fund principally invests differ from
conventional bonds in that principal is repaid over the life of the investment
rather than at maturity. As a result, the holder of the investment (i.e., the
Fund) receives monthly scheduled payments of principal and interest and may
receive unscheduled principal payments representing prepayments on the
underlying mortgages or loans. When the holder reinvests the payments and any
unscheduled prepayments of principal it receives, it may receive a rate of
interest that is higher or lower than the rate on the existing investment.

RESETS
  The Fund invests in ARMS and adjustable rate CMOs that hold securities whose
interest rates are readjusted at intervals of up to three years (generally one
year or less) to an increment over some predetermined interest rate index.
    

  There are three main categories of indices: (1) those based on U.S. Treasury
securities; (2) those derived from a calculated measure, such as a cost of funds
index; or (3) a moving average of mortgage rates. Commonly utilized indices
include the one-year, three-year and five-year constant maturity Treasury rates,
the three-month Treasury Bill rate, the 180-day Treasury Bill rate, rates on
longer-term Treasury securities, the 11th District Federal Home Loan Bank Cost
of Funds, the National Median Cost of Funds, the one-month, three-month,
six-month or one-year London Interbank Offered Rate ("LIBOR"), the prime rate of
a specific bank and commercial paper rates. Some indices, such as the one-year
constant maturity Treasury rate, closely mirror changes in market interest rate
levels. Others, such as the 11th District Home Loan Bank Cost of Funds Index,
tend to lag behind changes in market rate levels and tend to be somewhat less
volatile.

   
  The Fund's net asset value per share could vary to the extent that current
interest rates on Mortgage Securities are different than market interest rates
during periods between coupon reset dates. During periods of rising or falling
interest rates, changes in the coupon rate lag behind changes in the market rate
possibly resulting in a net asset value per share that is slightly lower or
higher, as the case may be, until the coupon resets to market rates.
Shareholders could lose some of their principal loss if they sold their shares
of the Fund during periods of rising interest rates before the interest rates on
the underlying mortgages or loans were adjusted to reflect current market rates.
During periods of fluctuations in interest rates, the Fund's net asset value per
share will fluctuate as well.

CAPS AND FLOORS
  The Fund invests in ARMS and CMOs whose underlying securities will frequently
have "caps" and "floors" that limit the maximum amount by which the loan rate to
the borrower may change up or down per reset or adjustment interval and over the
life of the loan.

  The Fund will not benefit from increases in interest rates to the extent that
interest rates rise to the point where they cause the current coupon of loans or
mortgages held as investments to reach their maximum allowable annual or
lifetime reset limits (cap rates). An increase in interest rates above the cap
rates would cause such mortgages or loans to "cap out" and to behave more like
long-term fixed rate debt securities. Conversely, the Fund will not benefit from
decreases in interest rates to the extent that prepayments increase. In
addition, when interest rates decline, the Fund's income will be reduced when
the interest rates on underlying adjustable rate mortgages are reduced.

ADDITIONAL FACTORS
  In an environment where interest rates on short-term fixed-rate debt
securities are rising faster than interest rates on long-term fixed-rate debt
securities, the market value of Mortgage Securities will typically underperform
other fixed-rate debt securities. In addition, because of the user risk
described above, the Fund's investments may not perform as expected.

  ARMS are less effective as a means of "locking in" long-term interest rates
than fixed-rate debt securities, since their market values will generally vary
inversely with changes in market interest rates, (i.e., declining when interest
rates rise and rising when interest rates decline). However, the market value of
ARMS is less likely to decline than fixed-rate debt securities of comparable
maturities during periods of rapidly rising rates. In addition, ARMS have less
potential than fixed-rate debt securities for capital appreciation due to their
adjustable rate features and the likelihood of increased prepayments of
mortgages as interest rates decline.

  If ARMS are purchased at a premium, unscheduled principal prepayments may
result in some loss of the holder's principal investment to the extent of the
premium paid over the face value of the security. On the other hand, if ARMS are
purchased at a discount, both a scheduled payment of principal and an
unscheduled prepayment of principal will increase current and total returns and
will accelerate the recognition of income, which, when distributed to
shareholders, will be taxable as ordinary income.

  While the Fund may invest in securities that are issued or guaranteed by the
U.S. government, its agencies or instrumentalities, the market value of such
securities is not guaranteed.

  For further information about the risks associated with the Fund's investments
and investment techniques, see the section of this prospectus entitled
"Additional Investment Information" and the statement of additional information.

PRICING SHARES
  The net asset value of a Fund share is computed each day on which the New York
Stock Exchange (the "Exchange") is open as of the close of trading on the
Exchange (currently 4:00 p.m. eastern time for purposes of pricing Fund shares)
except on days when changes in the value of the Fund's portfolio securities do
not affect the current 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 Fund is arrived at by determining the value of the Fund's
assets, subtracting its liabilities and dividing the result by the number of its
shares outstanding.
    

  The Fund values most of its securities at the mean of the bid and asked price
at the time of valuation and values other securities at fair value according to
procedures established by the Board of Trustees, including valuing certain of
its fixed rate Mortgage Securities on the basis of valuations provided by a
pricing service approved by the Fund's Board of Trustees, which uses information
with respect to transactions in Mortgage Securities, quotations from dealers,
market transactions in comparable securities and various relationships between
securities in determining value.

   
  The Fund values securities (1) with maturities of sixty days or less at
amortized cost (original purchase cost as adjusted for amortization of premium
or accretion of discount), which, when combined with accrued interest,
approximates market; (2) securities with remaining maturities of 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; (3) all other investments are valued at
market value or, where market quotations are not readily available, at fair
value as determined in good faith in accordance with procedures established by
the Board of Trustees.

DIVIDENDS AND TAXES
  The Fund has qualified, and intends to continue to qualify, as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code"). The Fund qualifies if, among other things, it distributes to its
shareholders at least 90% of its net investment income for its fiscal year. The
Fund also intends to make timely distributions, if necessary, sufficient in
amount to avoid the nondeductible 4% excise tax imposed on a regulated
investment company when 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.

  If the Fund qualifies as a regulated investment company, 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 Fund intends to declare dividends from net investment income daily and
distribute to its shareholders such dividends monthly and declare and distribute
all net realized capital gains if any, annually. Shareholders receive Fund
distributions in the form of additional shares of that class of shares upon
which the distribution is based or, at the shareholder's option, in cash.

  Because Class Y shares bear most of the costs of distribution of such shares
through an annual distribution fee, expenses attributable to Class Y shares will
generally be higher than those of Class Z shares, and income distributions paid
by the Fund with respect to Class Z shares will generally be greater than those
paid with respect to Class Y shares.

  Dividends and distributions other than capital gains 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 advises its shareholders
annually as to the federal tax status of all distributions made during the year.

  Any such distribution declared in October, November or December to
shareholders of record in such month and paid by the following January 31 would
be includable in the taxable income of shareholders as if paid on December 31 of
the year in which the distribution was declared.

  The Fund intends to distribute its net long-term capital gains as capital gain
dividends; such dividends are treated by shareholders as long-term capital
gains. Such distributions will be designated as long-term capital gain dividends
by a written notice mailed to each shareholder no later than 60 days after the
close of the Fund's fiscal year. If a shareholder receives a capital gain
dividend, then any allowable loss on disposition of Fund shares will be treated
as a long-term capital loss to the extent of such capital gain dividend, if such
shares have been held for six months or less.
    

  Since none of the Fund's income will consist of corporate dividends, no
distributions will qualify for the corporate dividends received deduction.

   
FUND 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 general supervision of the Fund's Board of Trustees, Keystone is
responsible for the overall management of the Fund's business and affairs.

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

  Keystone Investments is a private 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, Ralph J. Spuehler, Jr. and Rosemary D. Van
Antwerp. Keystone Investments provides accounting, bookkeeping, legal,
personnel and general corporate services to Keystone, its affiliates and the
Keystone Investments Family of Funds.
    

  Pursuant to its Investment Advisory and Management Agreement with the Fund
(the "Advisory Agreement"), Keystone provides investment advisory and management
services to the Fund. The Fund pays Keystone a fee for its services at the
annual rate of 0.30% of the average daily net asset value of the shares of the
Fund. A pro-rata portion of the fee is payable in arrears at the end of each day
or calendar month as Keystone may, from time to time, specify to the Fund.

   
  The Advisory Agreement continues in effect from year to year only so long as
such continuance is specifically approved at least annually by (i) the Fund's
Board of Trustees or by vote of a majority of the outstanding shares of the Fund
and (ii) by the vote of a majority of the Independent Trustees (Trustees who are
not interested persons, as defined in the 1940 Act of the Fund, as defined in
the 1940 Act) 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 Fund or Keystone, or by a vote of shareholders of
the Fund. The Advisory Agreement will terminate automatically upon its
assignment.

  Keystone Investments has recently entered into an Agreement and Plan of
Acquisition and Merger with First Union Corporation ("First Union"), pursuant to
which Keystone Investments will be merged with and into a wholly-owned
subsidiary of First Union National Bank of North Carolina ("FUNB-NC") (the
"Merger"). The surviving corporation will assume the name of "Keystone
Investments, Inc." Subject to a number of conditions being met, it is currently
anticipated that the Merger will take place on or around December 11, 1996.
Thereafter, Keystone Investments, Inc. would be a subsidiary of FUNB-NC.

  If consummated, the proposed Merger will be deemed to cause an assignment,
within the meaning of the 1940 Act, of the Advisory Agreement. Consequently, the
completion of the Merger is contingent upon, among other things, the approval of
the Fund's shareholders of a new investment advisory and management agreement
between the Fund and Keystone (the "New Advisory Agreement"). The Fund's
Trustees have approved the terms of the New Advisory Agreement, subject to the
approval of shareholders and the completion of the Merger, and have called a
special meeting of shareholders to obtain their approval of, among other things,
the New Advisory Agreement. The meeting is expected to be held in December 1996.
The proposed New Advisory Agreement has terms, including fees payable
thereunder, that are substantively identical to those in the current agreement.

   In addition to an assignment of the Fund's Advisory Agreement, the Merger, if
consummated, will also be deemed to cause an assignment, as defined by the 1940
Act, of the Principal Underwriting Agreement between the Fund and Fiduciary
Investment Company, the Fund's Principal Underwriter ("FICO"). As a result, the
Fund's Trustees have approved the following agreements, subject to the Merger's
completion: (i) a principal underwriting agreement between Evergreen Funds
Distributor, Inc. ("EFD") and the Fund; (ii) a marketing services agreement
between Keystone Investment Distributors Company ("KIDC") and EFD with respect
to the Fund; and (iii) a subadministration agreement between Keystone and Furman
Selz LLC with respect to the Fund. EFD is a wholly-owned subsidiary of Furman
Selz LLC. KIDC is a wholly owned subsidiary of Keystone. It is currently
anticipated that on or about January 2, 1997, Furman Selz LLC will transfer EFD
and Furman Selz LLC's related services to BISYS Group, Inc. ("BISYS") (the
"Transfer"). The Fund's Trustees have also approved, subject to completion of
the Transfer, (i) a new principal underwriting agreement between KIDC and EFD
with respect to the Fund; (ii) a new marketing services agreement between EFD
with respect to the Fund; and (iii) a subadministration agreement between
Keystone and BISYS with respect to the Fund. The terms of such agreements will
be substantively identical to the terms of the agreements to be executed upon
completion of the Merger.

  The Fund has adopted a Code of Ethics incorporating policies on personal
securities trading as recommended by the Investment Company Institute.

PORTFOLIO MANAGER
  Christopher P. Conkey has been the Fund's portfolio manager since 1991. Mr.
Conkey is a Keystone Senior Vice President and Group Leader for the high grade
fixed income area. Mr. Conkey joined Keystone as a fixed income portfolio
manager in January, 1988.

FUND EXPENSES
  Pursuant to the Advisory Agreement, Keystone has agreed to pay certain of the
Fund's expenses, including expenses of the Fund's transfer agent, custodian and
auditors; fees payable to government agencies, including registration and
qualification fees of the Fund and its shares under federal and state securities
laws; expenses of preparing, printing and mailing Fund prospectuses, notices,
reports and proxy material; and expenses of shareholders' and Trustees'
meetings. In addition to the investment advisory and management fee discussed
above, the principal expenses that the Fund is expected to pay include expenses
of its Independent Trustees; brokerage commissions, interest charges and taxes;
legal fees and certain extraordinary expenses. Each class will pay all of the
expenses attributable to it. Such expenses are currently limited to Distribution
Plan expenses.

  During the fiscal year ended September 30, 1996, Keystone voluntarily limited
the expenses of the Fund's Class Y and Class Z shares to .55% and .30%,
respectively, of average net class assets annually. Keystone reserves the right
at any time, however, to make a redetermination of whether to continue these
expense limits and, if so, at what rates.

  For the fiscal year ended September 30, 1996, the Fund paid or accrued to
Keystone investment management and advisory services fees of $121,105 which
represented 0.30% of the Fund's average net assets. For the fiscal year ended
September 30, 1996, the Fund paid .55% and .30% of the average annual net assets
of the Class Y and Class Z shares, respectively, in expenses.

SECURITIES TRANSACTIONS
  Under policies established by the Board of Trustees, Keystone selects
broker-dealers to execute transactions subject to the receipt of best execution.
When selecting broker-dealers to execute portfolio transactions for the Fund,
Keystone may consider the number of shares of the Fund sold by the
broker-dealer. In addition, broker-dealers executing portfolio transactions,
from time to time, may be affiliated with the Fund, Keystone, FICO, or their
affiliates.

  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.

PORTFOLIO TURNOVER
  The Fund's portfolio turnover rates for the fiscal years ended September 30,
1996 and 1995 were 85% and 56%, respectively.

HOW TO BUY SHARES
   Shares of the Fund are sold through FICO. FICO, a wholly-owned subsidiary of
Keystone, is located at 200 Berkeley Street, Boston, Massachusetts 02116-5034.
Shares are sold without a sales charge at the public offering price, which is
equal to the net asset value per share next computed after the Fund receives the
purchase order on each day on which the Exchange is open for business.
    

  Shares are held in "open accounts," i.e., they are credited to the
shareholder's account on the Fund's books. No certificates are issued. All
orders for the purchase of shares are subject to acceptance by the Fund, which
has the right to reject any order.

  Shares become entitled to income distributions declared on the first business
day following receipt by the Fund's transfer agent of payment for the shares.

   
OPENING AN ACCOUNT
  First, telephone Keystone Investor Resource Center, Inc. ("KIRC"), the Fund's
transfer agent and dividend disbursing agent, toll free at 1-800-633-2700 to
open an account and 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
  Boston, Massachusetts
  ABA 011000028 Attn: Mutual Fund Division
  For incoming wire A/C 0127-654-2
  For credit to KIARF
  Client Name and/or
  Account 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 appropriate, KIRC may require additional documentation or verification of
authority.

  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.
    

ALTERNATIVE SALES OPTIONS 
  The Fund offers two classes of shares.

CLASS Y SHARES
  Class Y shares are sold without a sales charge at the time of purchase and are
not subject to a sales charge when they are redeemed. Class Y shares are
available to any investor making a minimum initial purchase aggregating
$1,000,000 or more. There is no minimum amount required for subsequent
purchases.

   
  The Fund has adopted a Distribution Plan with respect to its Class Y shares
("Class Y Distribution Plan"), that provides for payments at an annual rate of
up to 0.35% of the average daily net asset value of Class Y shares, to pay
expenses of the distribution of Class Y shares. Payments are expected to be at a
rate of 0.25% of the average daily net assets of Class Y shares. Amounts paid by
the Fund under the Class Y Distribution Plan are generally used to pay FICO and
others' service fees. The Fund may also make payments to FICO, dealers and
others for activities that are primarily intended to result in sales of Class Y
shares, including, but not limited to, mail promotions and advertising,
including the use of member name and address lists of affinity groups,
professional associations, trade groups, industry associations or other
associations (e.g., credit union trade groups), for which use royalty payments
may be made. As a result, income distributions paid by the Fund with respect to
Class Y shares will generally be less than those paid with respect to Class Z
shares. See "Distribution Plan" below.

CLASS Z SHARES
  Class Z shares are sold without a sales charge at the time of purchase and are
not subject to a sales charge when they are redeemed. Class Z shares are
available to the following investors making a minimum initial purchase
aggregating $1,000,000 or more: officers, directors or trustees, and employees
of the Fund, Keystone, FICO, or any of their affiliates, and members of the
immediate families of such persons, or any trust, pension, profit-sharing, or
other retirement or benefit plan for the benefit of such persons; present
shareholders of Class Z shares of the Fund; and existing investment advisory
clients of Keystone Institutional Company, Inc., FICO, or any of their
affiliates. There is no minimum amount required for subsequent purchases.

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
  From time to time, FICO may provide promotional incentives to certain dealers
whose representatives have sold or are expected to sell significant amounts of
the Fund. In addition, from time to time, broker-dealers may receive additional
cash payments. FICO may provide written information to broker-dealers with whom
it has dealer agreements that relates to sales incentive campaigns conducted by
such broker-dealers for their representatives as well as financial assistance in
connection with pre-approved seminars, conferences and advertising. No such
programs or additional compensation will be offered to the extent they are
prohibited by the laws of any state or any self-regulatory agency, such as the
National Association of Securities Dealers ("NASD").

  FICO may, at its own expense, pay concessions in addition to those described
above to broker-dealers that satisfy certain criteria established from time to
time by FICO. These conditions relate to increasing sales of shares of the
Keystone funds over specified periods and certain other factors. Such payments
may, depending on the broker-dealer's satisfaction of the required conditions,
be periodic and may be up to 0.25% of the value of shares sold by such
broker-dealer.

  FICO may also pay a transaction fee (up to the level of the payments allowed
to broker-dealers for the sale of such shares, as described above) to banks and
other financial services firms that facilitate transactions in shares of the
Fund.
    

  The Glass-Steagall Act currently 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 under the arrangement described above, 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, and banks and financial
institutions may be required to register as broker-dealers pursuant to state
law.
    

DISTRIBUTION PLAN
  As discussed above, the Fund bears some of the costs of selling its Class Y
shares under a Distribution Plan adopted with respect to its Class Y shares
pursuant to Rule 12b-1 under the 1940 Act. Payments under the Class Y
Distribution Plan are limited to up to 0.35% annually of the average daily net
asset value of Class Y shares.

   
  The NASD limits the amount that the Fund may pay annually in distribution
costs for the sale of its shares and shareholder service fees. The NASD
currently limits annual expenditures to 1% of the aggregate average daily net
asset value of its shares, of which 0.75% may be used to pay such distribution
costs and 0.25% may be used to pay shareholder service fees. The NASD also
limits the aggregate amount that the Fund may pay for such distribution costs to
6.25% of gross share sales since the inception of the 12b-1 Distribution Plan,
plus interest at the prime rate plus 1% on such amounts remaining unpaid from
time to time.
    

  The Class Y Distribution Plan may be terminated at any time by vote of the
Independent Trustees or by vote of a majority of the outstanding voting shares
of Class Y.

   
  Payments pursuant to the Class Y Distribution Plan are included in the
operating expenses of that class.

HOW TO REDEEM SHARES
  You may redeem shares of the Fund at net asset value by mail or by using the
telephone or telecommunication redemption privilege.
    

MAIL REDEMPTIONS
  Shares may be redeemed 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 U.S.
stock exchange member, a bank or other persons eligible to guarantee signatures
under the Securities Exchange Act of 1934 and KIRC's 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. The Fund and KIRC may waive this requirement or
may require additional documentation in certain cases.

TELEPHONE OR TELECOMMUNICATION  REDEMPTIONS
  You may redeem shares on each day on which the Exchange is open for business
by telephone (toll free 1-800-633-2700), mailgram, fax or other request not
bearing a signature and a signature guarantee to KIRC.
    

  Shareholders must complete and sign the Account Application, including the
Redemption Authorization Section.

   
  Redemption proceeds will be wired in federal funds only to the commercial bank
(and account number) designated by the shareholder on the Account Application.
If KIRC deems it appropriate, additional documentation may be required. Although
at present KIRC pays the wire costs involved, it reserves the right at any time
to require the shareholder to pay such costs.
    

  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.

   
  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 address above.
    

  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.

   
REDEMPTION OF SHARES IN GENERAL
  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.

  The Fund computes the amount due you at the close of the Exchange at the end
of the day on which it has received all proper documentation from you. Payment
will be made within seven days after a properly completed redemption request is
received.

  The Fund may temporarily suspend the right to redeem or may extend 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.
    

SHAREHOLDER SERVICES

   
  Details on all shareholder services may be obtained from KIRC by calling toll
free 1-800-633-2700 or from FICO by writing to FICO at 200 Berkeley Street,
Boston, Massachusetts 02116-5034.

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 or herself 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. Subaccounts may be opened with the initial investment or at a later
date and may be established by an investor with registration either by name or
by number.

PERFORMANCE DATA
  From time to time, the Fund may advertise "total return" and "current yield."
ALL DATA IS BASED ON HISTORICAL RESULTS. PAST PERFORMANCE SHOULD NOT BE
CONSIDERED REPRESENTATIVE OF RESULTS FOR ANY FUTURE PERIOD OF TIME. Total return
and current yield are computed separately for each class of shares of the Fund.
Total return refers to the Fund's average annual compounded rates of return over
specified periods determined by comparing the initial amount invested in a
particular class to the ending redeemable value of that amount. The resulting
equation assumes reinvestment of all dividends and distributions and deduction
of all recurring charges, if any, applicable to all shareholder accounts.
    

  Current yield quotations represent the yield on an investment for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum offering price per share on the last day of the
base period.

   
FUND SHARES
  The Fund currently issues Class Y and Z shares, which participate in dividends
and distributions and have equal voting, liquidation and other rights except
that (1) expenses related to the distribution of each class of shares or other
expenses that the Board of Trustees may designate as class expenses, from time
to time, are borne solely by each class; (2) each class of shares has exclusive
voting rights with respect to its Distribution Plan, if any; and (3) each class
has a different designation. When issued and paid for, the shares will be fully
paid and nonassessable by the Fund. Shares will have no preference, conversion,
exchange or preemptive rights. Shares are transferable, redeemable and freely
assignable as collateral. There are no sinking fund provisions. The Fund is
authorized to issue additional classes or series of shares.

  Shareholders are entitled to one vote for each full share owned and fractional
votes for fractional shares on all matters subject to Fund vote. Shares of the
Fund vote together except when required by law to vote separately by series or
class. 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 Declaration of Trust of the Fund,
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 holders of 10% of the outstanding shares request a meeting. As
prescribed by Section 16(c) of the 1940 Act, shareholders may be eligible for
shareholder communication assistance in connection with the special meeting.

  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.

ADDITIONAL INFORMATION
  Except as otherwise stated in this prospectus or required by law, the Fund
reserves the right to change the terms of the offer stated in this prospectus
without shareholder approval, including the right to impose or change fees for
services provided.

- --------------------------------------------------------------------------------
                      ADDITIONAL INVESTMENT INFORMATION
- ------------------------------------------------------------------------------

  The Fund may engage in the following investment practices to the extent
described in the prospectus and the statement of additional information.

REPURCHASE AGREEMENTS
  The Fund may enter into repurchase agreements with member banks of the Federal
Reserve System having 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 must be registered as U.S. government securities
dealers with an appropriate 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. Under a repurchase agreement, the seller must maintain the value of the
securities subject to the agreement at not less than the repurchase price, such
value being 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 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 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.

REVERSE REPURCHASE AGREEMENTS
  Under a reverse repurchase agreement, the Fund would sell securities and agree
to repurchase them at a mutually agreed upon date and price. The Fund intends to
enter into reverse repurchase agreements to avoid otherwise having to sell
securities during unfavorable market conditions in order to meet redemptions. At
the time the Fund enters into a reverse repurchase agreement, it will establish
a segregated account with the Fund's custodian containing liquid assets such as
U.S. government securities or other high grade debt securities having a value
not less than the repurchase price (including accrued interest) and will
subsequently monitor the account to ensure such value is maintained. Reverse
repurchase agreements involve the risk that the market value of the securities
the Fund is obligated to repurchase may decline below the repurchase price.

   
COLLATERALIZED MORTGAGE OBLIGATIONS
    
  The Fund will invest only in CMOs issued or guaranteed by the U.S. government,
its agencies or instrumentalities. The Fund intends to invest only in CMOs that,
in Keystone's opinion, are suitable in light of the Fund's investment objective
and policies. The Fund may purchase any class of CMO other than the residual
(final) class or a class whose average life would extend or is shortened by more
than 6 years under modeling scenarios where mortgage commitment rates
immediately rise or fall 300 basis points.

  CMOs are debt obligations collateralized by Mortgage Securities and may be
issued by and guaranteed as to principal and interest by the U.S. government,
its agencies or instrumentalities or by private originators of, or investors in,
mortgage loans, including savings and loan associations, mortgage banks,
commercial banks, investment banks and special purpose subsidiaries of the
foregoing. The principal governmental issuer of CMOs is FNMA. In addition, FHLMC
issues a significant number of CMOs. The secondary market for CMOs is actively
traded.

  CMOs are structured by redirecting the total payment of principal and interest
on the underlying Mortgage Securities used as collateral to create classes with
different interest rates, maturities and payment schedules. Instead of interest
and principal payments on the underlying Mortgage Securities being passed
through or paid pro-rata to all holders of interests in the underlying Mortgage
Securities, each class of a CMO is paid from and secured by a separate priority
payment of the cash flow generated by the pledged Mortgage Securities.

  Most CMO issues have at least four classes. Classes with earlier maturities
receive priority on payments to assure the early maturity. After the first class
is redeemed, excess cash flow not necessary to pay interest on the remaining
classes is directed to the repayment of the next maturing class until that class
is fully redeemed. This process continues until all classes of the CMO issue
have been paid in full. Among the CMO classes available are floating
(adjustable) rate classes, which have characteristics similar to ARMS and
inverse floating rate classes whose coupons vary inversely with the rate of some
market index.

                                    THE FUND


         The Fund is an open-end,  diversified  management  investment  company,
commonly known as a mutual fund. The Fund was formed as a Massachusetts business
trust on June 19,  1991.  The Fund is one of more than thirty  funds  advised by
Keystone Investment Management Company ("Keystone"), the Fund's investment
adviser.

         Certain information about the Fund is contained in its prospectus. This
statement of additional  information  provides additional  information about the
Fund.

                             INVESTMENT RESTRICTIONS

         The Fund has adopted the fundamental investment  restrictions set forth
below  which may not be changed  without  the vote of a  majority  of the Fund's
outstanding voting shares (as defined in the Investment Company Act of 1940 (the
"1940 Act") as the lesser of (1) 67% of the shares  represented  at a meeting at
which more than 50% of the  outstanding  shares are represented or (2) more than
50% of the outstanding  shares).  Unless otherwise stated, all references to the
assets of the Fund are in terms of current market value.

         The Fund may not do the following:

         (1) with respect to 75% of its total assets, invest more than 5% of the
value of its total assets in the securities of any one issuer;  this  limitation
does not apply to  investments  in  securities  issued or guaranteed by the U.S.
government, its agencies or instrumentalities;

         (2)  invest  more than 5% of its  total  assets  in  securities  of any
company  having a record,  together  with its  predecessors,  of less than three
years of continuous operations;

         (3) pledge more than 15% of its net assets to secure indebtedness;  the
purchase  or sale of  securities  on a when  issued  basis is not deemed to be a
pledge of assets;

         (4) borrow money or enter into reverse  repurchase  agreements,  except
that the Fund may enter into reverse repurchase  agreements or borrow money from
banks for temporary or emergency  purposes in aggregate  amounts up to one-third
of the value of the Fund's net assets; provided that while borrowings from banks
(not  including  reverse  repurchase  agreements)  exceed 5% of the  Fund's  net
assets, any such excess borrowings will be repaid before additional  investments
are made;

         (5)  make  loans,  except  that  the Fund  may  purchase  or hold  debt
securities consistent with its investment  objective,  lend portfolio securities
valued  at not  more  than 15% of its  total  assets  to  brokers,  dealers  and
financial institutions, and enter into repurchase agreements;

         (6) make short sales of securities or maintain a short position, unless
at all  times  when a short  position  is open it 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, and
equal in amount to, the securities sold short;

         (7) issue senior  securities;  the purchase or sale of  securities on a
when issued basis is not deemed to be the issuance of a senior security;

         (8)  purchase  securities  on margin,  except  that it may obtain  such
short-term  credit as may be necessary  for the clearance of purchases and sales
of securities;

         (9) purchase more than 3% of the total outstanding voting securities of
any one investment  company,  invest more than 5% of its total assets in any one
investment  company or invest  more than 10% of its total  assets in  investment
companies  in general,  except as part of a merger,  consolidation,  purchase of
assets or similar transaction;

         (10)  purchase  or sell  commodities  or  commodity  contracts  or real
estate,  except that it may purchase and sell securities  secured by real estate
and  securities  of  companies  which  invest in real  estate  and may engage in
financial futures contracts and related options transactions; and

         (11) underwrite  securities of other issuers,  except that the Fund may
purchase  securities from the issuer or others and dispose of such securities in
a manner consistent with its investment objective.

         If a  percentage  limit  is  satisfied  at the  time of  investment  or
borrowing,  a later increase or decrease  resulting from a change in asset value
of a security or a decrease in Fund assets is not a violation of the limit.


                             DISTRIBUTIONS AND TAXES


         The Fund intends to distribute its net investment  income daily and its
net capital gains, if any, annually.  You will receive  distributions as shares,
unless you elect,  before the payable  date for income  dividends  or the record
date for capital gains  distributions,  to receive them as cash. Unless the Fund
receives  instructions to the contrary,  it will assume that you wish to receive
that  distribution  and future gains and income  distributions  in shares.  Your
instructions  continue in effect until changed in writing. If you have not opted
to receive  cash,  the Fund will  determine the number of shares that you should
receive  based on its net  asset  value per  share as  computed  at the close of
business on the ex-dividend date after adjustment for the distribution.
        
         Capital  gains  distributions  that  reduce the net asset value of your
shares  below your cost are,  to the extent of the  reduction,  a return of your
investment.  Since  distributions  of capital gains depend upon profits realized
from the sale of the Fund's portfolio securities, they may or may not occur.

         Distributions   are  taxable  whether  you  receive  them  in  cash  or
additional  shares.  Long-term  capital gains  distributions are taxable as such
regardless  of how long you have  held the  shares.  If,  however,  you hold the
Fund's  shares  for less than six months  and  redeem  them at a loss,  you will
recognize a long-term  capital loss to the extent of the long-term  capital gain
distribution received in connection with such shares.

         The Fund intends to  distribute  only such net capital gains and income
as it has predetermined,  to the best of its ability,  to be taxable as ordinary
income.  The Fund distributes its net investment  income on a federal income tax
basis, not based on distributable income as computed on our books. The Fund does
not expect its income dividends to qualify for the corporate  dividends received
deduction.

         The Fund will advise you  annually as to the federal  income tax status
of your distributions.  These comments relating to the taxation of dividends and
distributions  paid  on the  Fund's  shares  relate  solely  to  federal  income
taxation.  Your  dividends  and  distributions  may also be subject to state and
local taxes.


                             VALUATION OF SECURITIES


         Current  values for the Fund's  portfolio  securities are determined in
the following manner:

         (1)  securities for which market  quotations are readily  available are
valued  at  market  value,  which is  deemed to be the mean of the bid and asked
prices at the time of valuation;

         (2) (a) short-term  investments  that 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;

             (b)  short-term  investments  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;

           (c) short-term instruments having maturities of more than sixty days,
for which market quotations are readily available,  are valued at current market
value; and

         (3)  securities,  including  restricted  securities,  for which  market
quotations  are not  readily  available,  and other  assets are valued at prices
deemed in good faith to be fair under procedures established by the Fund's Board
of Trustees.

         The Fund  believes that reliable  market  quotations  are generally not
readily  available  for  purposes of valuing  certain  securities.  As a result,
depending on the particular securities owned by the Fund, it is likely that most
of the  valuations  for such  obligations  will be based  upon  their fair value
determined  under  procedures  that have been approved by the Board of Trustees.
The Board of Trustees has authorized  the use of a pricing  service to determine
the fair value of the Fund's fixed rate mortgage securities.


                                    BROKERAGE


         It is the policy of Keystone,  in effecting  transactions in the Fund's
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
broker's  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 judgmental and 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 is considered to be in addition to,
and not in lieu of,  services  required to be  performed  by Keystone  under its
Investment  Advisory  and  Management  Agreement  with the Fund  (the  "Advisory
Agreement").  The cost,  value and specific  application of such information are
indeterminable  and  cannot be  practically  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 effected for such other clients. Under the
Advisory  Agreement,  Keystone is permitted to pay higher brokerage  commissions
for  brokerage  and research  services in  accordance  with Section 28(e) of the
Securities  Exchange  Act of 1934.  In the event  Keystone  does  follow  such a
practice, it will do so on a basis that is fair and equitable to the Fund.

         The  Fund  expects  that  purchases  and  sales of its  securities  and
temporary  instruments usually will be principal  transactions.  Adjustable rate
and fixed rate  securities  and  temporary  instruments  are normally  purchased
directly  from  the  issuer  or from an  underwriter  or  market  maker  for the
securities.  There usually will be no brokerage commissions paid by the Fund for
such  purchases.  Purchases  from  underwriters  will  include the  underwriting
commission or concession,  and purchases  from dealers  serving as market makers
will  include  a  dealer's  mark-up  or  reflect  a  dealer's  mark-down.  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  direct  purchase  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.

         Neither Keystone nor the Fund intends to place securities  transactions
with  any  particular  broker-dealer  or  group  thereof.  The  Fund's  Board of
Trustees,  however,  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.

         The Fund's Board of Trustees  periodically reviews the Fund's brokerage
policy.  In the event of further  regulatory  development  affecting  securities
exchanges and brokerage practices  generally,  the Board of Trustees may change,
modify or eliminate any of the foregoing practices.

         Investment  decisions for the Fund are made  independently  by Keystone
from those of the other funds and investment  accounts  managed by Keystone.  It
may frequently develop,  however,  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.

         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.


                                DISTRIBUTION PLAN

GENERAL

         The  Fund  offers  Class Y and Z  shares.  Class Y shares  are  offered
without an initial  sales charge and are not subject to a sales charge when they
are redeemed. Class Y shares make payments under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act (the "Class Y Distribution Plan").

         Class Z shares are also  offered  without a sales charge at the time of
purchase and are not subject to a sales charge when they are redeemed.  There is
no  distribution  plan  with  respect  to Class Z  shares.  Class Z  shares  are
available  only  to  certain  investors.   The  prospectus  contains  a  general
description of how investors may buy shares of the Fund.

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund, to use their assets to bear expenses of distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing  certain  provisions  set forth in Rule  12b-1.  The  Fund's  Class Y
Distribution Plan has been approved by the Fund's Board of Trustees, including a
majority of the Independent Trustees (Trustees who are not interested persons of
the  Fund,  as  defined  in the 1940 Act,  and who have no  direct  or  indirect
financial  interest in the Fund's  Distribution  Plan or any  agreement  related
thereto).

         The National  Association of Securities  Dealers,  Inc. ("NASD") limits
the amount that the Fund may pay annually in distribution  costs for sale of its
shares and  shareholder  service fees.  The NASD limits annual  expenditures  to
1.00% of the  aggregate  average  daily net asset value of its shares,  of which
0.75%  may be used to pay such  distribution  costs and 0.25% may be used to pay
shareholder  service fees.  The NASD also limits the  aggregate  amount that the
Fund may pay for such distribution costs to 6.25% of gross share sales since the
inception of the Class Y Distribution Plan, plus interest at the prime rate plus
1.00% on such amounts remaining unpaid from time to time.

CLASS Y DISTRIBUTION  PLAN. The Class Y Distribution Plan provides that the Fund
may expend  daily  amounts at an annual  rate up to 0.35% of the Fund's  average
daily net asset value  attributable  to Class Y shares to finance  any  activity
that is  primarily  intended to result in the sale of Class Y shares,  including
without  limitation,  expenditures  consisting of the payment of service fees to
FICO or  others.  Such  payments  are  expected  to be at a rate of 0.25% of the
average daily net assets of Class Y shares.

         Amounts  paid by the  Fund  under  the  Class Y  Distribution  Plan are
currently used to pay FICO and others,  such as broker-dealers,  service fees at
an annual  rate of up to 0.25% of the  average  daily net asset value of Class Y
shares  maintained by FICO and such others and  outstanding  on the books of the
Fund  for  specified  periods.   The  Fund  may  also  make  payments  to  FICO,
broker-dealers  and others for activities that are primarily  intended to result
in sales of the Fund's  Class Y shares,  including,  but not  limited  to,  mail
promotions and  advertising,  including the use of member name and address lists
of  affinity  groups,   professional   associations,   trade  groups,   industry
associations, or other associations, for which use royalty payments may be made.

         The Class Y Distribution  Plan may be terminated,  at any time, by vote
of the Independent  Trustees or by vote of a majority of the outstanding  voting
shares of the Fund's Class Y shares. Any change in the Class Y Distribution Plan
that would materially  increase the distribution  expenses of the Fund's Class Y
shares  provided  for in the  Class Y  Distribution  Plan  requires  shareholder
approval.  Otherwise,  the  Class Y  Distribution  Plan  may be  amended  by the
Trustees, including the Independent Trustees.

         The total amounts paid by the Fund under the foregoing arrangements may
not exceed the maximum Class Y Distribution  Plan limit specified above, and the
amounts and purposes of expenditures under the Class Y Distribution Plan must be
reported to the Independent  Trustees  quarterly.  The Independent  Trustees may
require or approve  changes in the  implementation  or  operation of the Class Y
Distribution Plan and may also require that total expenditures by the Fund under
the Class Y  Distribution  Plan be kept  within  limits  lower than the  maximum
amount permitted by the Distribution Plan as stated above.

         While  the Class Y  Distribution  Plan is in  effect,  the Fund will be
required to commit the selection and  nomination of candidates  for  Independent
Trustees to the discretion of the Independent Trustees.

         The Independent  Trustees of the Fund have determined that the sales of
the Fund's Class Y shares resulting from payments under the Class Y Distribution
Plan have benefit the Fund.

                               INVESTMENT ADVISER


         Subject to the general  supervision  of the Fund's  Board of  Trustees,
Keystone is responsible  for the overall  management of the Fund's  business and
affairs.  Keystone has provided  investment  advisory and management services to
investment companies and private accounts since 1932. Keystone is a wholly-owned
subsidiary of Keystone Investments, Inc. ("Keystone Investments"). Both Keystone
and  Keystone   Investments  are  located  at  200  Berkeley   Street,   Boston,
Massachusetts 02116-5034.

         Keystone  Investments is a private  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, Ralph J. Spuehler, Jr. and Rosemary D.
Van Antwerp.  Keystone  Investments  provides  accounting,  bookkeeping,  legal,
personnel and general corporate services to Keystone Management, Inc. ("Keystone
Management"),  Keystone, their affiliates and the Keystone Investments Family of
Funds.

         Pursuant to the Advisory  Agreement,  Keystone  manages and administers
the Fund's  operation and manages the investment and  reinvestment of the Fund's
assets in conformity with the Fund's investment objective and restrictions.

         The  Advisory  Agreement  stipulates  that  Keystone  shall (i) provide
office space and all  necessary  office  facilities,  equipment and personnel in
connection with its services under the Advisory Agreement; (ii) pay or reimburse
the Fund for the  compensation  of  officers  and  Trustees  of the Fund who are
affiliated  with  Keystone  and (iii) pay all  expenses of Keystone  incurred in
connection  with the  provision  of its  services.  In addition,  Keystone  also
assumes and pays or reimburses  the Fund for (i) all charges and expenses of any
custodian or depository  appointed by the Fund for the  safekeeping of its cash,
securities and other property; (ii) all charges and expenses for bookkeeping and
auditors;  (iii) all charges and expenses of any transfer  agents and registrars
appointed by the Fund; (iv) all costs of certificates representing shares of the
Fund;  (v) all  fees  and  expenses  involved  in  registering  and  maintaining
registrations  of the Fund and of its shares with the  Securities  and  Exchange
Commission  (the  "Commission")  and  registering or qualifying its shares under
state or other securities laws, including,  without limitation,  the preparation
and  printing  of  registration  statements,   prospectuses  and  statements  of
additional  information  for filing with the Commission  and other  authorities;
(vi) expenses of preparing,  printing and mailing prospectuses and statements of
additional  information  to  shareholders  of the Fund;  (vii) all  expenses  of
shareholders'  and  Trustees'  meetings and of  preparing,  printing and mailing
notices, reports and proxy materials to shareholders of the Fund; and (viii) all
charges and expenses of filing annual and other reports with the  Commission and
other authorities.

         The Fund  assumes and pays all other  expenses of the Fund,  including,
without  limitation,  (i)  fees of the  Fund's  Independent  Trustees;  (ii) all
brokers' fees,  expenses and commissions and issue and transfer taxes chargeable
to the Fund in  connection  with  transactions  involving  securities  and other
property  to  which  the  Fund is a party;  (iii)  all  costs  and  expenses  of
distribution of its Class Y shares incurred pursuant to its Class Y Distribution
Plan  adopted  pursuant to Rule 12b-1  under the 1940 Act;  (iv) all charges and
expenses of legal counsel for the Fund and for the Fund's  Independent  Trustees
on routine legal matters relating to the Fund,  including,  without  limitation,
legal services rendered in connection with the Fund's existence,  business trust
and financial  structure and relations with its shareholders,  registrations and
qualifications of securities under federal,  state and other laws, and issues of
securities;  (v) all  taxes  and  business  trust  fees  payable  by the Fund to
federal,  state or other governmental  agencies;  (vi) all interest costs of the
Fund; and (vii) all  extraordinary  expenses and charges of the Fund,  including
all  charges  and  expenses  of legal  counsel  to the Fund in  connection  with
extraordinary matters,  including,  without limitation, any litigation involving
the Fund,  its Trustees,  officers,  employees or agents.  In the event Keystone
provides  any of these  services  or pays any of these  expenses,  the Fund will
promptly reimburse Keystone therefor.

         The Fund pays Keystone a fee for its services to the Fund at the annual
rate of 0.30% of the average  daily net asset value of the shares of the Fund. A
pro rata  portion  of the fee is  payable  in  arrears at the end of each day or
calendar month as Keystone may, from time to time, specify to the Fund.

         Currently,  Keystone has voluntarily limited the annual expenses of the
Fund to no more than  0.55%  and 0.30% of Class Y and Class Z average  daily net
assets,  respectively.  Keystone  intends  to  continue  the  foregoing  expense
limitations  on a calendar  month-by-month  basis.  Keystone  will  periodically
evaluate the foregoing  expense  limitations and may modify or terminate them in
the  future.Keystone  will not be required to reimburse  the Fund for amounts in
excess of an  expense  limit if such  reimbursement  would  result in the Fund's
inability to qualify as a regulated  investment  company under provisions of the
Internal Revenue Code of 1986, as amended (the "Code").

         The  Advisory  Agreement  continues in effect only if approved at least
annually  (i) by the Board of Trustees of the Fund or by a vote of a majority of
the  outstanding  shares,  and (ii) by the vote of a majority of the Independent
Trustees  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 Fund's  Board of  Trustees  or by a vote of a majority of
outstanding   shares  of  the  Fund.  The  Advisory   Agreement  will  terminate
automatically upon its "assignment" as that term is defined in the 1940 Act.

         Keystone Investments has recently entered into an Agreement and Plan of
Acquisition and Merger with First Union Corporation ("First Union"), pursuant to
which  Keystone  Investments  will  be  merged  with  and  into  a  wholly-owned
subsidiary  of  First  Union  National  Bank of North  Carolina  ("FUNB-NC")(the
"Merger").  The surviving  corporation  assume the name  "Keystone  Investments,
Inc." Subject to a number of conditions  being met, it is currently  anticipated
that the Merger  will take place on or around  December  11,  1996.  Thereafter,
Keystone Investments, Inc. would be a subsidiary of FUNB-NC.

         If  consummated,  the  proposed  merger  may  be  deemed  to  cause  an
assignment,  within  the  meaning  of the 1940 Act,  of the  Advisory  Agreement
between the Adviser and the Fund. Consequently,  the completion of the Merger is
contingent upon, among other things, the approval of the Fund's  shareholders of
a new investment advisory and management agreement between the Fund and Keystone
(the "New Advisory" Agreement").  The Funds' Trustees have approved the terms of
the New  Advisory  Agreement,  subject to the approval of  shareholders  and the
completion of the Merger,  and have called a special  meeting of shareholders to
obtain their approval of, among other things,  such  agreements.  The meeting is
expected to be held in December  1996.  The proposed New Advisory  Agreement has
terms,   including  investment  advisory  fees  payable  thereunder,   that  are
substantively identical to those in the current agreement.



                                   DISTRIBUTOR


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

         FICO, as agent, currently has the right to obtain subscriptions for and
to  sell  shares  of  the  Fund.   In  so  doing  FICO  may  retain  and  employ
representatives to promote distribution of the shares and may obtain orders from
brokers-dealers or others for sales of shares to them. No such representative or
broker-dealer  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.  FICO  may  receive  payments  from  the  Fund  pursuant  to the  Class Y
Distribution Plan.

         All  subscriptions  and  sales  of  shares  by FICO  are at the  public
offering price of the shares, as determined 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.  FICO has also
agreed that it 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, 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  provides that it will remain in effect for
two years and from year to year  thereafter as long as its terms and continuance
are approved by a majority of the Fund's Independent  Trustees at least annually
at a  meeting  called  for that  purpose,  and if its  continuance  is  approved
annually  by vote of a majority  of  Trustees,  or by vote of a majority  of the
outstanding shares of the Fund.

         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.

         The proposed transaction may also be deemed to cause an assignment,  as
defined by the 1940 Act,  of the  Distribution  Agreement  between  the Fund and
FICO. As a result,  the Fund's Trustees have approved the following  agreements,
subject to the completion of the Merger: (i) a principal  underwriting agreement
between Evergreen Funds Distributor, Inc. ("EFD") and the Fund; (ii) a marketing
services  agreement  between KIDC and EFD with respect to the Fund;  and (iii) a
subadministration agreement between the Adviser and Furman Selz LLC with respect
to the Fund.  EFD is a  wholly-owned  subsidiary  of Furman Selz LLC.  KIDC is a
wholly-owned  subsidiary of Keystone. It is expected that on or about January 2,
1997, Furman Selz LLC will transfer EFD, and Furman Selz LLC's related services,
to BISYS Group, Inc.  ("BISYS") (the "Transfer").  The Fund's Trustees have also
approved,   subject  to  completion  of  the  Transfer:   (i)  a  new  principal
underwriting  agreement between EFD and the Fund; (ii) a new marketing  services
agreement   between   KIDC  and  EFD  with   respect   to  Fund;   and  (iii)  a
subadministration  agreement  between the Adviser and BISYS with  respect to the
Fund. The terms of such agreements are  substantively  identical to the terms of
the agreements to be executed upon completion of the Merger.


                              DECLARATION OF TRUST


MASSACHUSETTS BUSINESS TRUST

         The  Fund  is  a  Massachusetts  business  trust  established  under  a
Declaration  of Trust  dated June 19,  1991,  as amended  (the  "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 is on
file as an  exhibit  to the  Fund's  Registration  Statement.  This  summary  is
qualified in its entirety by reference to the Declaration of Trust.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of  beneficial  interest of classes of shares.  Each share of the Fund
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  or  class.
Shareholders have no preemptive or conversion rights.  Shares are redeemable and
transferable.  The Fund offers Class Y and Z but may issue additional classes or
series of shares.

SHAREHOLDER LIABILITY

         Pursuant to certain decisions of the Massachusetts courts, shareholders
of a  Massachusetts  business  trust may, under certain  circumstances,  be held
personally  liable  for the  obligations  of the Fund.  The  possibility  of the
shareholders incurring financial loss for that reason 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 Fund property for any shareholder held personally  liable for the obligations
of the Fund.

VOTING RIGHTS

         Under the  terms of the  Declaration  of Trust,  the Fund does not hold
annual  meetings.  At meetings called for the initial election of Trustees or to
consider  other  matters  shares  are  entitled  to one vote per  share.  Shares
generally vote together as one class on all matters. No amendment may be made to
the Declaration of Trust that adversely  affects any class of shares without the
approval of a majority of the shares of that class.  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 50% or less of the
shares voting will not be able to elect any Trustees.

         After the initial meeting  electing  Trustees,  no further  meetings of
shareholders  for the purpose of electing  Trustees will be held unless required
by law or unless  and until such time as less than a  majority  of the  Trustees
holding  office have been  elected by  shareholders,  at which time the Trustees
then in office will call a shareholders' meeting for election of Trustees.

         Except as set forth above,  the Trustees  shall continue to hold office
indefinitely,  unless  otherwise  required  by law,  and may  appoint  successor
Trustees. A Trustee may be removed from or cease to hold office (as the case may
be) (1) at any time by two-thirds vote of the remaining Trustees;  (2) when such
Trustee  becomes  mentally  or  physically  incapacitated;  or (3) at a  special
meeting of shareholders by a two-thirds vote of the Fund's  outstanding  shares.
Any Trustee may 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 and, if reasonable  care has been exercised in the
selection of officers,  agents,  employees or investment advisers,  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.

DISTRIBUTION PLAN EXPENSES

During the fiscal year ended  September 30,, 1996, the Fund paid $23,210 to FICO
under its Distribution Plan. For more information, see "Distribution Plans."

BROKERAGE COMMISSIONS

The Fund paid no brokerage  commissions for the fiscal years ended September 30,
1994, 1995 and 1996. For more information, see "Brokerage."

                 STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS

         Total return  quotations  for a class of shares of the Fund as they may
appear from time to time in advertisements are calculated by finding the average
annual  compounded  rates of return over one, five and ten year periods,  or the
time  periods for which such class of shares has been  effective,  whichever  is
relevant,  on a  hypothetical  $1,000  investment  that would equate the initial
amount  invested  in the class to the ending  redeemable  value.  To the initial
investment  all dividends and  distributions  are added,  and all recurring fees
charged to all shareholder  accounts are deducted.  The ending  redeemable value
assumes a complete redemption at the end of the relevant periods.

         The annual  total  return for Class Y shares for the fiscal  year ended
September 30, 1996,  was 6.60%.  Average  annual total return for Class Y shares
for the period May 23, 1994  (commencement  of  operations),  through the fiscal
period ended September 30, 1996, was 5.77%.

         The annual total return for Class Z for the fiscal year ended September
30, 1996, was 6.86%.  The average annual total return for Class Z for the period
October 1, 1991  (commencement of operations),  through  September 30, 1996, was
5.20%.

         Current  yield  quotations  as they may appear,  from time to time,  in
advertisements will consist of a quotation based on a 30-day period ended on the
date of the most recent balance sheet of the Fund,  computed by dividing the net
investment  income per share  earned  during the period by the maximum  offering
price per share on the last day of the base period. The current yields for Class
Y and Class Z for the 30-day  period  ended  September  30,  1996 were 6.07% and
6.36%, respectively.

         Any given  yield or total  return  quotation  should not be  considered
representative of the Fund's yield or total return for any future period.

                              FINANCIAL STATEMENTS

         The  following  financial  statements of the Fund are  incorporated  by

                             ADDITIONAL INFORMATION


SMALL ACCOUNTS

         The Fund  reserves  the right to redeem  shares in any account in which
the value of  shares  is less  than  $1,000.  The  redemption  proceeds  will be
promptly  paid to the  shareholder.  Shareholders  will  be  notified  if  their
accounts  are less than such amount and given 60 days to bring the account up to
such amount before the redemption is made.

REDEMPTIONS IN KIND

         If conditions  arise that would make it undesirable for the Fund to pay
for all  redemptions  in  cash,  the Fund may  authorize  payment  to be made in
portfolio securities or other property.  The Fund has obligated itself under the
1940 Act, however, 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 net  assets.  Securities  delivered  in payment of  redemptions  would be
valued at the same value  assigned to them in computing  the net asset value per
share  and  would,  to the  extent  permitted  by law,  be  readily  marketable.
Shareholders  receiving such  securities  would incur brokerage costs when these
securities are sold.

                           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.  Government
National  Mortgage   Association   ("GNMA")  securities  include  GNMA  mortgage
pass-through  certificates.  Such securities are supported by the full faith and
credit of the U.S. government.

     Securities   issued  or   guaranteed   by  U.S.   government   agencies  or
instrumentalities include securities issued or guaranteed by the Federal Housing
Administration,  Farmers Home  Administration,  Export-Import  Bank of the U.S.,
Small Business Administration, 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
securities of Federal Home Loan Banks,  are supported by the right of the issuer
to  borrow  from the  Treasury.  Others,  such as bonds  issued  by the  Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  The U.S.  government is not obligated by law to
provide support to an instrumentality it sponsors.  U.S.  government  securities
held by the Fund do not include  international  agencies or instrumentalities in
which the U.S. government, its agencies or instrumentalities  participate,  such
as the World Bank,  Asian  Development  Bank or the  Inter-American  Development
Bank, or issues insured by the Federal Deposit Insurance Corporation.

                             CORPORATE BOND RATINGS

S&P RATINGS

     A Standard & Poor's Corporation  ("S&P") corporate bond rating is a current
assessment of the creditworthiness of an obligor, including obligors outside the
United States, with respect to a specific  obligation.  This assessment may take
into consideration obligors such as guarantors, insurers, or lessees. Ratings of
foreign  obligors  do not  take  into  account  currency  exchange  and  related
uncertainties.  The ratings are based on current  information  furnished  by the
issuer or obtained by S&P from other sources it considers reliable.

     The ratings are based, in varying degrees, on the following considerations:

     1.  likelihood of default - capacity and  willingness  of the obligor as to
the timely payment of interest and repayment of principal in accordance with the
terms of the obligation;

     2. nature of and provisions of the obligation; and

     3.  protection  afforded by and relative  position of the obligation in the
event of  bankruptcy,  reorganization  or other  arrangement  under  the laws of
bankruptcy and other laws affecting creditors' rights.

         PLUS (+) OR MINUS (-): To provide more detailed  indications  of credit
quality,  ratings  from AAto Amay be modified by the addition of a plus or minus
sign to show relative standing within the major rating categories.

         Eligible bond ratings are as follows:

     1. AAA - Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.

     2. AA - Debt rated AA has a very strong capacity to pay interest and
repay principal and differs from the higher rated issues only in small degree.

Moody's Ratings

     Eligible  ratings of Moody's  Investors  Service,  Inc.  ("Moody's") are as
follows:

     1. Aaa - Bonds  that are  rated Aaa are  judged to be of the best  quality.
They carry the smallest degree of investment risk and are generally  referred to
as  "gilt-edge."   Interest   payments  are  protected  by  a  large  or  by  an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair fundamentally strong position of such issues.

     2. Aa - Bonds  that are rated Aa are  judged to be of high  quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present that
make the long term risks appear somewhat larger than in Aaa securities.

     Moody's  applies  numerical  modifiers  1, 2 and 3 in each  generic  rating
classification  from Aa  through B in its  corporate  bond  rating  system.  The
modifier 1 indicates  that the  security  ranks in the higher end of its generic
rating category;  the modifier 2 indicates a mid-range ranking; and the modifier
3  indicates  that  the  issue  ranks in the  lower  end of its  generic  rating
category.

                       ADJUSTABLE RATE SECURITIES RATINGS

S&P RATINGS

     An S&P rating of an issue  secured by a pool of  mortgages  is a measure of
the  likelihood  that cash flow from the  mortgages  is  sufficient  for  timely
payment of interest and principal on the rated  security.  Each rating  category
generally  defines  an  adverse  economic  climate  that is likely to impact the
performance  of the  mortgages  in the pool over time.  The rating  process  for
commercial mortgages, like all asset-backed financings, involves a credit, legal
structure and cash flow analysis.

     The  credit  analysis  involves  an  analysis  of  the  originator  and  an
evaluation  of the credit  quality of the loans and their risk  characteristics,
such as property types, geographic locations, loan maturity dates, loan-to-value
ratios, lien status and loan seasoning.

     The legal structure analysis involves a review of legal documents to
determine the documents  accurately reflect the specifics of the financing and a
review of flow of funds  and  investment  restrictions  of any  reserve  fund or
credit enhancement.

     The cash flow  analysis  involves  identification  of the type of  security
created out of the cash flow from the pool of commercial mortgages and the
payment terms of the security.  Once these items are identified,  the individual
loan and pool  analysis are applied to  determine  cash flow  scenarios  for the
pool.

     Eligible ratings are as follows:

     1. AAA - Securities  rated AAA have the highest rating  assigned by S&P and
reflect certainty that the issuer at all times will have pledged collateral such
that  scheduled  cash  flow and  assumed  reinvestment  income  thereon  will be
sufficient  to pay annual  interest on the  securities  and redeem  principal at
maturity.

     2. AA - Securities rated AA reflect  certainty that amounts  available from
distributions  on the mortgage loans and from reserves will be sufficient to pay
monthly interest and return principal.

MOODY'S RATINGS

     Moody's rating  provides a system of gradation by which the relative credit
risks of  investments  in  adjustable  rate  securities  can be judged.  Moody's
factors  into its ratings  the  frequency,  serverity  and timing of defaults in
order to provide an  assessment  of the  appropriate  risk premium for taking on
credit risk. In rating adjustable rate securities,  Moody's uses the same letter
system as that for corporate  bonds.  In assessing  risk, on average,  the risks
associated  with  Aaa and Aa  rated  Moody's  corporate  bonds  would  apply  to
adjustable securities rated Aaa or Aa by Moody's. See the description of Moody's
corporate bond ratings set forth above.

                            MONEY MARKET INSTRUMENTS

     Money market  securities are instruments  with remaining  maturities of one
year  or less  such  as bank  certificates  of  deposit,  bankers'  acceptances,
commercial  paper  (including  master  demand notes) and  obligations  issued or
guaranteed by the U.S. government,  its agencies or  instrumentalities,  some of
which may be subject to repurchase agreements.

COMMERCIAL PAPER

     Commercial  paper will  consist of issues rated at the time of purchase A-1
by S&P, Prime-1 by Moody's, or F-1 by Fitch Investors Service, Inc. ("Fitch's");
or, if not rated,  will be issued by  companies  that have an  outstanding  debt
issue rated at the time of purchase Aaa, Aa or A by Moody's,  or AAA, AA or A by
S&P, or will be determined by Keystone to be of comparable quality.

S&P RATINGS

     An S&P commercial paper rating is a current assessment of the likelihood of
timely  payment of debt  having an  original  maturity of no more than 365 days.
Ratings  are  graded  into four  categories,  ranging  from "A" for the  highest
quality obligations to "D" for the lowest. The top category is as follows:

     1. A:  Issues  assigned  this  highest  rating are  regarded  as having the
greatest  capacity for timely  payment.  Issues in this category are  delineated
with the numbers 1, 2 and 3 to indicate the relative degree of safety.

     2. A-1:  This  designation  indicates  that the degree of safety  regarding
timely payment is either overwhelming or very strong. Those issues determined to
possess  overwhelming  safety  characteristics  are denoted with a plus (+) sign
designation.

MOODY'S RATINGS

     The term "commercial paper" as used by Moody's means promissory obligations
not having an original  maturity in excess of nine  months.  Moody's  commercial
paper  ratings  are  opinions  of the  ability of  issuers  to repay  punctually
promissory obligations not having an original maturity in excess of nine months.
Moody's  employs the following  designation,  judged to be investment  grade, to
indicate the relative repayment capacity of rated issuers.

     The rating  Prime-1 is the  highest  commercial  paper  rating  assigned by
Moody's.  Issuers rated Prime-1 (or related supporting  institutions) are deemed
to have a superior capacity for repayment of short term promissory  obligations.
Repayment  capacity of Prime-1  issuers is normally  evidenced by the  following
characteristics:

         1. leading market positions in well-established industries;
         2. high rates of return on funds employed;
         3. conservative capitalization structures with moderate
             reliance on debt and ample asset protection;
         4. broad margins in earnings coverage of fixed financial
            charges and high internal cash generation; and
         5. well established access to a range of financial markets and
            assured sources of alternate liquidity.

     In assigning  ratings to issuers whose  commercial  paper  obligations  are
supported by the credit of another  entity or entities,  Moody's  evaluates  the
financial strength of the affiliated  corporations,  commercial banks, insurance
companies,  foreign governments or other entities, but only as one factor in the
total rating assessment.

CERTIFICATES OF DEPOSIT

     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 United States 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
assets as of the date of their most recently published financial statements,  or
of savings and loan  associations  that are  members of the Federal  Savings and
Loan  Insurance  Corporation,  and have at least $1  billion in assets as of the
date of their most recently published financial statements.

     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.  Additionally,  the Fund does not
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,
uncondition-ally  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 assets at the time of purchase in excess of $1 billion and must be payable
in U.S. dollars.
