     Keystone High Income Bond Fund (B-4) (the "Fund") is a mutual fund whose
investment objective is generous income. The generous income sought by the Fund
is ordinarily associated with high yield, high risk bonds and similar securities
in the lower rating categories of the recognized rating agencies or with
securities that are unrated.

     Your purchase payment is fully invested. There is no sales charge when you
buy the Fund's shares. With certain exceptions, the Fund imposes a deferred
sales charge, which declines from 4.00% to 1.00%, if you redeem your shares
within four years of purchase.

     The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under the
Investment Company Act of 1940 (the "1940 Act") under which it bears some of the
costs of selling its shares to the public.

     This prospectus sets forth concisely the 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 November 29, 1996, as supplemented from time to
time, 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
listed above.

     SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK, AND SHARES ARE NOT INSURED OR OTHERWISE PROTECTED BY THE
U.S. GOVERNMENT, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE
BOARD, OR ANY OTHER GOVERNMENT AGENCY AND INVOLVE RISK, INCLUDING THE POSSIBLE
LOSS OF PRINCIPAL.

FUND DESCRIPTION
- ------------------------------------------------------------------------------

  The Fund is an open-end, diversified management investment company, commonly
known as a mutual fund. The Fund was created under Pennsylvania law as a common
law trust and has been offering its shares continuously since September 11,
1935. The Fund is one of more than thirty funds advised and managed by Keystone
Investment Management Company ("Keystone"), the Fund's investment
adviser.

- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------

INVESTMENT OBJECTIVE
  The Fund's investment objective is to provide shareholders with generous
income.

  The Fund's investment objective is fundamental and cannot be changed without
the approval of a majority of the Fund's outstanding shares (as defined in the
1940 Act), 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 (a "1940 Act Majority").

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

PRINCIPAL INVESTMENTS
  Under normal circumstances, the Fund will invest at least 65% of its total
assets in bonds, debentures, and other income obligations. The Fund's portfolio
ordinarily includes a substantial number of bonds, debentures, and other income
obligations that are rated by Standard & Poor's Corporation ("S&P") or Moody's
Investors Service ("Moody's") as below investment grade, i.e., S&P rating below
BBB and Moody's rating below BAA.

  While growth of capital is not a Fund objective, the Fund may purchase
securities that offer the possibility of capital appreciation in addition to
income, provided the acquisition of such securities does not conflict with the
Fund's objective of generous income.

  The Fund may purchase securities with any rating or may purchase unrated
securities, which are not necessarily of lower quality than rated securities,
but may not be as attractive to as many buyers. While Keystone performs its own
credit analyses of the Fund's investments and does not rely on ratings assigned
by rating services, bonds rated below-investment grade generally involve greater
volatility of price and risk of principal and income than bonds in the higher
rating categories and are, on balance, considered predominantly speculative.

  In addition to its other investment options, the Fund may invest in limited
partnerships, including master limited partnerships, and may invest up to 25% of
its assets in foreign securities. The Fund may also invest in participations in
bank loans.

OTHER ELIGIBLE INVESTMENTS
  When market conditions warrant, the Fund may invest up to 100% of its assets
for temporary or defensive purposes in short-term investments. Such investments,
which must mature within one year of their purchase, consist of United States
("U.S.") government securities; instruments, including certificates of deposit,
demand and time deposits and bankers' acceptances, of banks that are members of
the Federal Deposit Insurance Corporation and have assets of at least $1
billion, including U.S. branches of foreign banks and foreign branches of U.S.
banks; prime commercial paper, including master demand notes; and repurchase
agreements secured by U.S. government securities. When the Fund invests for
defensive purposes, it seeks to limit the loss of principal and is not pursuing
its investment objective.

  The Fund's investments may include fixed and adjustable rate or stripped
bonds, including zero coupon bonds and payment-in-kind securities ("PIKs"),
debentures, notes, equipment trust certificates, U.S. government securities, and
debt securities convertible into or exchangeable for preferred or common stock.
The Fund may continue to hold preferred or common stock received in connection
with convertible or exchangeable securities. The Fund may also invest in units
consisting of debt securities with stock or warrants to buy stock attached.

  The Fund may also invest in preferred stock, including convertible preferred
stock and adjustable rate preferred stock; warrants, which may be used to create
other permissible investments; and common stock of issuers that are objects of
acquisition attempts, are undergoing reorganization through bankruptcy or
otherwise, or are in the process of refinancing. Investments in common stocks of
such issuers are expected to provide the Fund with the opportunity to receive
high-yielding, fixed-income securities. Investments in common stocks will be
limited to those stocks that Keystone believes will assist the Fund in achieving
its investment objective.

  The Fund intends to follow 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 the investment on its books
and (2) limiting its holdings of such securities to 15% of net assets.

  The Fund may invest in restricted securities, including securities eligible
for resale pursuant to Rule 144A under the Securities Act of 1933 (the "1933
Act"). Generally, Rule 144A establishes a safe harbor from the registration
requirements of the 1933 Act for resale by large institutional investors of
securities not publicly traded in the U.S. The Fund may purchase Rule 144A
securities when such securities present an attractive investment opportunity and
otherwise meet the Fund's selection criteria. The Board of Trustees has adopted
guidelines and procedures pursuant to which the liquidity of the Fund's Rule
144A securities is determined by Keystone, and the Board of Trustees monitors
Keystone's implementation of such guidelines and procedures.

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

  The Fund may (i) write covered call and put options; (ii) purchase call and
put options, including call and put options to close out existing positions; and
(iii) employ new investment techniques with respect to such options. The Fund
currently does not intend to invest more than 5% of its assets in options
transactions.

  The Fund may enter into reverse repurchase agreements and firm commitment and
when-issued transactions for securities and currencies. In addition, the Fund
may enter into currency and other financial futures contracts and related
options transactions for hedging purposes and not for speculation. The Fund may
also employ new investment techniques with respect to such futures contracts and
related options transactions. The Fund will supplement its prospectus if
appropriate in the event it employs any such new techniques.

  In addition to the options, futures contracts, and forwards mentioned above,
the Fund may also invest in certain other types of derivative instruments,
including collateralized mortgage obligations, structured notes, interest rate
swaps, index swaps, currency swaps, and caps and floors. These basic vehicles
can also be combined to create more complex products called hybrid derivatives
or structured securities.

  For further information about the types of investments and investment
techniques available to the Fund, including the associated risks, see the "Risk
Factors" and "Additional Investment Information" sections of this prospectus as
well as the statement of additional 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
nonfundamental restrictions are set forth in detail in the statement of
additional information.

  The Fund may not do the following: (1) with respect to 75% of its total
assets, invest more than 5% of its total assets, computed at market value at the
time of purchase, in the securities of any one issuer, or invest in more than
10% of the outstanding voting securities of any one issuer; provided that these
limitations do not apply to investments in securities issued or guaranteed by
the U.S. government and (2) borrow money, except that the Fund may borrow money
from banks for temporary or emergency purposes in aggregate amounts up to 10% of
the value of the Fund's net assets (computed at cost), or enter into reverse
repurchase agreements (bank borrowings and reverse repurchase agreements, in the
aggregate, shall not exceed 10% of the value of the Fund's net assets).

  In addition, the Fund may, notwithstanding any other investment policy or
restriction, invest all of its assets in the securities of a single open-end
management investment company with substantially the same fundamental investment
objective, policies, and restrictions as the Fund. The Fund does not currently
intend to implement this policy and would do so only if the Board of Trustees
were to determine such action to be in the best interest of the Fund and its
shareholders. In the event of such implementation, the Fund will comply with
such requirements as to written notice to shareholders as are then in effect.

- ------------------------------------------------------------------------------
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. YOU CAN LOSE MONEY BY
INVESTING IN THE FUND. YOUR INVESTMENT IS NOT GUARANTEED. A DECREASE IN THE
VALUE OF THE FUND'S PORTFOLIO SECURITIES CAN RESULT IN A DECREASE IN THE VALUE
OF YOUR INVESTMENT.

  Certain risks related to the Fund are discussed below. To the extent not
discussed in this section, specific risks attendant to individual securities or
investment practices are discussed in detail in "Additional Investment
Information" and the statement of additional information.

  By itself, the Fund does not constitute a balanced investment plan. The Fund
seeks generous income ordinarily from high yield, high risk bonds, commonly
known as "junk bonds." This investment approach involves risks greater than a
more conservative approach. You should take into account your own investment
objectives as well as your other investments when considering an investment in
the Fund.

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

BELOW-INVESTMENT GRADE BONDS
  Since 1935, the Fund has had continuous experience investing in bonds selling
at a substantial discount from par, convertible bonds, below- investment grade
bonds, and other securities that as a class may be considered high yield, high
risk securities.

  Prior to the 1980's, corporate bonds were primarily issued to finance growth
and development. Below-investment grade bonds were predominantly bonds that
often traded at discounts from par because the company's credit ratings had been
downgraded. The rapid growth of the below-investment grade sector of the bond
market during the 1980's was largely attributable to the issuance of such bonds
to finance corporate reorganizations. An economic downturn could severely
disrupt the market for high yield, high risk bonds and adversely affect the
value of outstanding bonds and the ability of issuers to repay principal and
interest.

  Although the change in the size and characteristics of the market may result
in higher risks associated with individual bonds, Keystone believes that an
effective program of broad diversification can, over time, enable the Fund to
successfully achieve its investment objective while reducing the risk of
investing in individual below-investment grade bonds.

  The generous income sought by the Fund is ordinarily associated with
securities in the lower rating categories of the recognized rating agencies or
with securities that are unrated. Such securities are generally rated BB or
lower by S&P or Ba or lower by Moody's. The Fund may invest in securities that
are rated as low as D by S&P and C- by Moody's. It is possible for securities
rated D or C-, respectively, to have defaulted on payments of principal and/or
interest at the time of investment. The section of this prospectus entitled
"Additional Investment Information" describes these rating categories. The Fund
intends to invest in D rated debt only in cases when, in Keystone's judgment,
there is a distinct prospect of improvement in the issuer's financial position
as a result of the completion of reorganization or otherwise. The Fund may also
invest in unrated securities that, in Keystone's judgment, offer comparable
yields and risks to those of securities that are rated, as well as in
below-investment quality zero coupon bonds or PIKs.

  Keystone considers the ratings of Moody's and S&P assigned to various
securities, but does not rely solely on those ratings because (1) Moody's and
S&P assigned ratings are based largely on historical financial data and may not
accurately reflect the current financial outlook of companies, and (2) there can
be large differences among the current financial conditions of issuers within
the same rating category.

  While an investment in the Fund provides opportunities to maximize return over
time, investors should be aware of the following risks associated with
below-investment grade bonds:

  (1) Securities rated BB or lower by S&P or Ba or lower by Moody's are
considered predominantly speculative with respect to the ability of the issuer
to meet principal and interest payments.

  (2) The lower ratings of certain securities held by the Fund reflect a greater
possibility that adverse changes in the financial condition of the issuer or in
general economic conditions, or both, or an unanticipated rise in interest rates
may impair the ability of the issuer to make payments of interest and principal,
especially if the issuer is highly leveraged. Such issuer's ability to meet its
debt obligations may also be adversely affected by specific corporate
developments, the issuer's inability to meet specific projected business
forecasts, or the unavailability of additional financing. Also, an economic
downturn or an increase in interest rates may increase the potential for default
by the issuers of these securities.

  (3) Their values are more sensitive to real or perceived adverse economic,
company or industry conditions and publicity than is the case for higher quality
securities.

  (4) Their value, like those of other fixed income securities, fluctuates in
response to changes in interest rates; generally rising when interest rates
decline and falling when interest rates rise. For example, if interest rates
increase after a fixed-income security is purchased, the security, if sold prior
to maturity, may return less than its cost. The prices of below- investment
grade bonds, however, are generally less sensitive to interest rate changes than
the prices of higher-rated bonds.

  (5) The secondary market for certain securities held by the Fund may be less
liquid at certain times than the secondary market for higher quality debt
securities, which may adversely effect (i) the market price of the security,
(ii) the Fund's ability to dispose of particular issues and (iii) the Fund's
ability to obtain accurate market quotations for purposes of valuing its assets.

  (6) Zero coupon bonds and PIKs involve additional special considerations. Zero
coupon bonds do not require the periodic payment of interest. PIK bonds are debt
obligations that provide that the issuer may, at its option, pay interest on
such bonds in cash or in the form of additional debt obligations. Such
investments may experience greater fluctuation in value due to changes in
interest rates than debt obligations that pay interest currently. Even though
these investments do not pay current interest in cash, the Fund is nonetheless
required by tax laws to accrue interest income on such investments and to
distribute such amounts at least annually to shareholders. Thus, the Fund could
be required at times to liquidate investments in order to fulfill its intention
to distribute substantially all of its net income as dividends.

  The following table shows the weighted average percentages of the Fund's
assets invested at the end of each month during the last fiscal year in
securities assigned to the various rating categories by S&P and in unrated
securities determined by Keystone to be of comparable quality. Since the
percentages in this table are based on month-end averages throughout the Fund's
fiscal year, they do not reflect the Fund's holdings at any one point in time.
The percentages in each category may be higher or lower on any day than those
shown in the table.

  Since the Fund takes an aggressive approach to investing, Keystone attempts to
maximize the return by controlling risk through diversification, credit
analysis, review of sector and industry trends, interest rate forecasts, and
economic analysis. Keystone's analysis of securities focuses on values based on
factors such as interest or dividend coverage, asset values, earnings prospects,
and the quality of management of the company. In making investment
recommendations, Keystone also considers current income, potential for capital
appreciation, maturity structure, quality guidelines, coupon structure, average
yield, percentage of zeros and PIKs, percentage of non-accruing items, and yield
to maturity.

  Income and yields on high yield, high risk securities, as on all securities,
will fluctuate over time.

FOREIGN RISK
  The Fund may invest up to 25% of its assets in securities that are principally
traded in securities markets outside the U.S. While investing in foreign
securities is intended to reduce risk by providing further diversification, such
investments do involve the following risks: publicly available information on
issuers and securities may be scarce; many foreign countries do not follow the
same accounting, auditing, and financial reporting standards as are used in the
U.S.; market trading volumes may be smaller, resulting in less liquidity and
more price volatility compared to U.S. securities of comparable quality; there
may be less regulation of securities trading and its participants; the
possibility may exist for expropriation, confiscatory taxation, nationalization,
establishment of exchange controls, political or social instability or negative
diplomatic developments; and dividend or interest withholding may be imposed at
the source.

  Fluctuations in foreign exchange rates impose an additional level of risk,
possibly affecting the value of the Fund's foreign investments and earnings, as
well as gains and losses realized through trades, and the unrealized
appreciation or depreciation of investments. The Fund may also incur costs when
it shifts assets from one country to another.

DERIVATIVE SECURITIES
  With respect to derivative or structured securities, the market value of such
securities may vary depending on the manner in which such securities have been
structured. As a result, the value of such investments may change at a more
rapid rate than that of traditional fixed income securities.

  For more detailed information on derivatives, see "Additional Investment
Information" and the statement of additional information.

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

  The Fund computes its net asset value as of the close of trading (currently
4:00 p.m. eastern time) on each day that the New York Stock Exchange (the
"Exchange") is open. However, the Fund does not compute its net asset value on
days when changes in the value of the Fund's securities do not affect the
current net asset value of its shares. The Exchange currently is 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 is arrived at by determining the value of all of the Fund's
assets, subtracting all liabilities and dividing the result by the number of
shares outstanding.

  Current values for the Fund's portfolio securities are determined as follows:

  (1) short-term investments with remaining 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;

  (2) short-term investments with greater than sixty days to maturity are
valued at market value; and

  (3) all other investments are valued at market value or, when market
quotations are not readily available, at fair value, as determined in good faith
by the Board of Trustees.

  The Fund believes that reliable market quotations are generally not readily
available for purposes of valuing certain fixed income securities. As a result,
it is likely that most of the valuations for such securities 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 income securities and
certain other securities.

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

  The Fund has qualified and intends to continue to qualify as a regulated
investment company (a "RIC") 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 RIC 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 RIC 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 will declare dividends from its net investment income daily and will
pay such dividends monthly. The Fund will distribute its net capital gains, if
any, at least annually. Shareholders receive Fund distributions in the form of
additional shares of the Fund or, at the shareholder's election (which must be
made before the record date for the distribution), in cash. Fund distributions
in the form of additional shares are made at net asset value without the
imposition of a sales charge.

  Dividends and distributions are taxable whether they are received in cash or
in shares. Income dividends and net short-term gains distributions are taxable
as ordinary income. Net long-term gains distributions are taxable as capital
gains regardless of how long the Fund's shares are held. If Fund shares held for
less than six months are sold at a loss, however, such loss will be treated for
tax purposes as a long-term capital loss to the extent of any long-term capital
gains dividends received. Any taxable dividend declared in October, November, or
December to shareholders of record in such month and paid by the following
January 31, will be includable in the taxable income of the shareholder as if
paid on December 31 of the year in which the dividend was declared.

  The Fund advises its shareholders annually as to the federal tax status of all
distributions made during the year. Dividends and distributions also may be
subject to state and local taxes.

- ------------------------------------------------------------------------------
FUND MANAGEMENT AND EXPENSES
- ------------------------------------------------------------------------------

FUND MANAGEMENT
  The Fund's Board of Trustees has absolute and exclusive control over the
management and disposition of all assets of the Fund. Subject to the authority
of the Fund's Board of Trustees, Keystone provides investment advice, management
and administrative services to the Fund.

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 First Union Keystone, Inc. ("First Union Keystone"). First Union
Keystone provides accounting, bookkeeping, legal, personnel and general
corporate services to Keystone, its affiliates and the Keystone Families of
Funds. Both First Union Keystone and Keystone are located at 200 Berkeley
Street, Boston, Massachusetts 02116-5034.

  On December 11, 1996, First Union Keystone succeeded to the business of a
corporation under different ownership. First Union Keystone is a wholly-owned
subsidiary of First Union National Bank of North Carolina ("FUNB"). FUNB is a
subsidiary of First Union Corporation ("First Union"), the sixth largest bank
holding company in the U.S. based on total assets as of December 31, 1996.

  First Union is headquartered in Charlotte, North Carolina, and had $140
billion in consolidated assets as of December 31, 1996. First Union and its
subsidiaries provide a broad range of financial services to individuals and
businesses throughout the U.S. The Capital Management Group of FUNB, together
with Lieber & Company and Evergreen Asset Management Corp., wholly-owned
subsidiaries of FUNB, manage or otherwise oversee the investment of over $60
billion in assets as of December 31, 1996 belonging to a wide range of clients,
including the Evergreen Family of Funds.

  Pursuant to its Investment Advisory and Management Agreement with the Fund
(the "Advisory Agreement"), Keystone manages the investment and reinvestment of
the Fund's assets, supervises the operation of the Fund and provides all
necessary office space, facilities and equipment.

  The Fund pays Keystone a fee for its services at the annual rate set forth
below:
                                                     AGGREGATE NET ASSET VALUE
MANAGEMENT                                                       OF THE SHARES
FEE                                 INCOME                         OF THE FUND
- ------------------------------------------------------------------------------
                                    2% of
                              gross dividend and
                               interest income
                                     plus
0.50% of the first                                          $100,000,000, plus
0.45% of the next                                           $100,000,000, plus
0.40% of the next                                           $100,000,000, plus
0.35% of the next                                           $100,000,000, plus
0.30% of the next                                           $100,000,000, plus
0.25% of amounts over                                       $500,000,000;

Keystone's fee is computed as of the close of business each business day and
payable monthly.

  The Advisory Agreement continues in effect for two years from its effective
date and, thereafter, from year to year only so long as such continuance is
specifically approved at least annually by the Board of Trustees or by the vote
of shareholders of the Fund. In addition, the terms and annual continuance of
the Advisory Agreement must be approved 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 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 may be terminated
by a vote of shareholders of the Fund. The Advisory Agreement will terminate
automatically upon its "assignment," as defined in the 1940 Act.

PRINCIPAL UNDERWRITER
  Evergreen Keystone Distributor, Inc. ("EKD" or the "Principal Underwriter"), a
subsidiary of The BISYS Group, Inc., ("BISYS") which is not affiliated with
First Union, is the Fund's principal underwriter. EKD replaced Evergreen
Keystone Investment Services, Inc. (formerly Keystone Investment Distributors
Company) ("EKIS") as the Fund's principal underwriter. EKIS may no longer act as
principal underwriter of the Fund due to regulatory restrictions imposed by the
Glass-Steagall Act upon national banks such as FUNB and their affiliates, that
prohibit such entities from acting as the underwriters or distributors of mutual
fund shares. While EKIS may no longer act as principal underwriter of the Fund
as discussed above, EKIS may continue to receive compensation from the Fund or
the Principal Underwriter in respect of underwriting and distribution services
performed prior to the termination of EKIS as principal underwriter. In
addition, EKIS may also be compensated by the Principal Underwriter for the
provision of certain marketing support services to the Principal Underwriter at
an annual rate of up to 0.75% of the average daily net assets of the Fund,
subject to certain restrictions. EKD is located at 125 W. 55th Street, New York
10019.

SUB-ADMINISTRATOR
  BISYS, or an affiliate, provides officers and certain administrative services
to the Fund pursuant to a sub-administrator agreement. For its services under
that agreement, BISYS, or an affiliate, receives a fee from Keystone at the
maximum annual rate of 0.01% of the average daily net assets of the Fund. BISYS
is located at 3435 Stelzer Road, Columbus, Ohio 43219.

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

PORTFOLIO MANAGER
  Prescott B. Crocker, a Senior Vice President and Portfolio Manager, is manager
of the Fund's portfolio. Prior to joining Keystone in February, 1997, Mr.
Crocker was president and chief investment officer of Boston Security
Counsellors, a private accounts investment management firm and a subsidiary of
Advest Co. Inc. He has more than 20 years of fixed-income investment experience.

FUND EXPENSES
  The Fund will pay all of its expenses. In addition to the investment advisory
and management fees discussed above, the principal expenses that the Fund is
expected to pay include, but are not limited to, expenses of its transfer agent,
its custodian, its independent auditors; expenses of legal counsel for the Fund
and for its Trustees in connection with legal matters relating to the Fund;
expenses under its Distribution Plan; fees and expenses of its Independent
Trustees (Trustees who are not interested persons, as defined in the 1940 Act,
of the Fund); expenses of shareholders' and Trustees' meetings; 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 certain extraordinary expenses. In addition to such expenses, the Fund pays
its brokerage commissions, interest charges, and taxes. For the fiscal year
ended July 31, 1996, the Fund paid 1.94% of its average net assets in expenses.

  During the fiscal year ended July 31, 1996, the Fund paid or accrued to
Keystone Management, Inc., the Fund's former investment manager, investment
management and advisory fees of $3,788,171 (0.56% of the Fund's average daily
net assets). Of such amount, $3,219,945 was paid to Keystone for investment
advisory services to the Fund. During the same period, the Fund paid or accrued
$18,334 to Keystone for certain accounting services and $1,927,228 to Evergreen
Keystone Service Company, (formerly Keystone Investor Resource Center, Inc.)
("EKSC"), for services rendered as the Fund's transfer and dividend disbursing
agent. EKSC, a wholly-owned subsidiary of Keystone, is located at 200 Berkeley
Street, Boston, Massachusetts 02116-5034.

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 such
broker-dealers. In addition, broker-dealers executing portfolio transactions
may, from time to time, be affiliated with the Fund, First Union Keystone,
Keystone, the Fund's principal underwriter, 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 July 31, 1996
and 1995 were 116% and 82%, respectively. High portfolio turnover may involve
correspondingly greater brokerage commissions and other transaction costs, which
would be borne directly by the Fund, as well as additional realized gains and/or
losses to shareholders. For further information on the tax consequences of such
realized gains and/or losses, see the "Dividends and Taxes" section of this
prospectus. For further information about brokerage and distributions, see the
statement of additional information.


- ------------------------------------------------------------------------------
DISTRIBUTION PLAN
- ------------------------------------------------------------------------------

  The Fund bears some of the costs of selling its shares under the Distribution
Plan. The Fund's Distribution Plan provides that the Fund may expend up to
0.3125% quarterly (1.25% annually) of the average daily net asset value of its
shares to pay distribution costs for sales of its shares and to pay shareholder
service fees. The NASD currently limits such 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 Fund's Distribution Plan, plus interest at the prime rate plus 1.00% on such
amounts (less any contingent deferred sales charge (a "CDSC") paid by
shareholders to the Principal Underwriter) remaining unpaid from time to time.

  Payments under the Distribution Plan are currently made to the Principal
Underwriter or its predecessor, EKIS, (which may reallow all or part to others,
such as broker-dealers) (1) as commissions for Fund shares sold; (2) as
shareholder service fees in respect of shares maintained by the recipients and
outstanding on the Fund's books for specified periods; and (3) interest. Amounts
paid or accrued to the Principal Underwriter and its predecessor in the
aggregate may not exceed the annual limitation referred to above.

  The Principal Underwriter generally reallows to broker-dealers or others a
commission equal to 4.00% of the price paid for each Fund share sold. In
addition, the Principal Underwriter generally reallows to broker-dealers or
others a shareholder service fee at a rate of 0.25% per annum of the net asset
value of shares maintained by such recipients and outstanding on the books of
the Fund for specified periods. See also "Arrangements with Broker-Dealers and
Others" below.

  The financing of payments made by the Principal Underwriter to compensate
broker-dealers or other persons for distributing shares of the Fund will be
provided by FUNB or its affiliates.

  If the Fund is unable to pay the Principal Underwriter a commission on a new
sale because the annual maximum (0.75% of average daily net assets) has been
reached, the Principal Underwriter intends, but is not obligated, to continue to
accept new orders for the purchase of Fund shares and to pay or accrue
commissions and service fees to broker-dealers in excess of the amount it
currently receives from the Fund ("Advances"). While the Fund is under no
contractual obligation to reimburse the Principal Underwriter or its predecessor
for Advances, the Principal Underwriter and its predecessor intend to seek full
payment of such Advances from the Fund (together with interest at the rate of
prime plus 1.00%) at such time in the future as, and to the extent that, payment
thereof by the Fund would be within permitted limits. EKIS currently intends to
seek payment of interest only on such Advances paid or accrued by the Principal
Underwriter subsequent to July 7, 1992. If the Fund's Independent Trustees
authorize such payments, the effect will be to extend the period of time during
which the Fund incurs the maximum amount of costs allowed by the Distribution
Plan.

  As of July 31, 1996, the maximum uncollected amounts for which EKIS, the
predecessor to the Principal Underwriter, may seek payment from the Fund under
its Distribution Plan is $5,597,863 (0.94% of the Fund's net asset value).

  The amounts and purposes of expenditures under the Distribution Plan must be
reported to the Independent Trustees quarterly. The Independent Trustees may
require or approve changes in the operation of the Distribution Plan and may
require that total expenditures by the Fund under the Distribution Plan be kept
within limits lower than the maximum amount permitted by the Distribution Plan
as stated above. Unless limited by the Independent Trustees, such costs could,
for some period of time, be higher than such costs permitted by most other plans
presently adopted by other investment companies.

  The Distribution Plan may be terminated at any time by vote of the Fund's
Independent Trustees or by vote of a majority of the outstanding voting shares
of the Fund. If the Distribution Plan is terminated, the Principal Underwriter
will ask the Independent Trustees to take whatever action they deem appropriate
under the circumstances with respect to payment of Advances.

  Any change in the Distribution Plan that would materially increase the
distribution expenses of the Fund provided for in the Distribution Plan requires
shareholder approval. Otherwise, the Distribution Plan may be amended by votes
of the majority of both (1) the Fund's Trustees and (2) the Independent Trustees
cast in person at a meeting called for the purpose of voting on such amendment.

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

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
  Upon written notice to broker-dealers, the Principal Underwriter may, at its
own expense, periodically sponsor programs that offer additional compensation in
connection with sales of Fund shares. Participation in such programs may be
available to all broker-dealers or to selected broker-dealers who have sold or
are expected to sell significant amounts of shares. Additional compensation may
also include financial assistance to broker-dealers in connection with
preapproved 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 NASD.

  The Principal Underwriter 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 the Principal Underwriter. These conditions
relate to increasing sales of shares of the Keystone funds over specified
periods and certain other factors. Such payments depending on the
broker-dealer's satisfaction of the required conditions, may be periodic and may
be up to 1.00% of the value of shares sold by such broker-dealer.

  The Principal Underwriter also may pay banks and other financial services
firms that facilitate transactions in shares of the Fund for their clients a
transaction fee up to the level of the payments made allowable to broker-dealers
for the sale of such shares as described above.

  The Glass-Steagall Act and other banking laws and regulations presently
prohibit member banks of the Federal Reserve System ("Member Banks") or their
non-bank affiliates from sponsoring, organizing, controlling or distributing the
shares of registered open-end investment companies such as the Fund. Such laws
and regulations also prohibit banks from issuing, underwriting or distributing
securities in general. However, under the Glass-Steagall Act and such other laws
and regulations, a Member Bank or an affiliate thereof may act as investment
adviser, transfer agent or custodian to a registered open-end investment company
and may also act as agent in connection with the purchase of shares of such an
investment company upon the order of its customer. Keystone and its affiliates,
since they are direct or indirect subsidiaries of FUNB, are subject to and in
compliance with the aforementioned laws and regulations. In the event the
Glass-Steagall Act is deemed to prohibit depository institutions from accepting
certain payments from the Fund, 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.

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

  You may purchase shares of the Fund from any broker-dealer that has a selling
agreement with the Principal Underwriter.

  In addition, you may purchase Fund shares by mailing to the Fund, c/o
Evergreen Keystone Service Company, P.O. Box 2121, Boston, Massachusetts
02106-2121, a completed account application and a check payable to the Fund. You
may also telephone 1-800-343-2898 to obtain the number of an account to which
you can wire or electronically transfer funds and then send in a completed
account application. Subsequent investments in the Fund's shares in any amount
may be made by check, by wiring Federal funds, by direct deposit or by
electronic funds transfer ("EFT").

  The Fund's shares are sold at the public offering price, which is equal to the
net asset value per share next computed after the Fund receives the purchase
order. The initial purchase must be at least $1,000, except for purchases by
participants in certain retirement plans for which the minimum is waived. There
is no minimum for subsequent purchases. Purchase payments are fully invested at
net asset value. There are no sales charges on purchases of Fund shares at the
time of purchase.


CONTINGENT DEFERRED SALES CHARGE
  With certain exceptions, when shares of the Fund are redeemed within four
calendar years after their purchase, the Fund may charge a CDSC as follows:
During the calendar year of purchase ................................... 4.00%
During the first calendar year after the year of purchase .............. 3.00%
During the second calendar year after the year of purchase ............. 2.00%
During the third calendar year after the year of purchase .............. 1.00%
Thereafter ............................................................. 0.00%

  If imposed, the CDSC is deducted from the redemption proceeds otherwise
payable to you. CDSCs are, to the extent permitted by the NASD, paid to the
Principal Underwriter or its predecessor.

  The CDSC is a declining percentage of the lesser of (1) the net asset value of
the shares redeemed or (2) the total cost of such shares. With respect to shares
purchased after January 1, 1997, no CDSC is imposed when a shareholder redeems
amounts derived from (1) increases in the value of the shares redeemed account
above the total cost of such shares due to increases in the net asset value per
share of the Fund; (2) certain shares with respect to which the Fund did not pay
a commission on issuance, including shares acquired through reinvestment of
dividend income and capital gains distributions; or (3) shares held in all or
part of more than four consecutive calendar years.

  Upon request for redemption, shares not subject to a CDSC will be redeemed
first. Thereafter, shares held the longest will be the first to be redeemed. No
CDSC is payable on permitted exchanges of shares between the funds in the
Keystone Classic Fund Family that have adopted distribution plans pursuant to
Rule 12b-1 under the 1940 Act. For purposes of computing CDSCs, when shares of
one fund are exchanged for shares of another fund, the date of purchase of the
shares being acquired by exchange is deemed to be the date the shares being
tendered for exchange were originally purchased.

WAIVER OF DEFERRED SALES CHARGE
  No CDSC is imposed on a redemption of shares of the Fund in the event of (1)
death or disability of the shareholder; (2) a lump-sum distribution from a 401
(k) plan or other benefit plan qualified under the Employee Retirement Income
Security Act of 1974 ("ERISA"); (3) automatic withdrawals from ERISA plans if
the shareholder is at least 59 1/2 years old; (4) involuntary redemptions of
accounts having an aggregate net asset value of less than $1,000; (5) automatic
withdrawals under a Systematic Income Plan of up to 1% per month of the
shareholder's initial account balance; (6) withdrawals consisting of loan
proceeds to a retirement plan participant; (7) financial hardship withdrawals
made by a retirement plan participant; or (8) withdrawals consisting of returns
of excess contributions or excess deferral amounts made to a retirement plan
participant.

  Shares also may be sold, to the extent permitted by applicable law, at net
asset value without the payment of commissions or the imposition of a CDSC to
(1) certain Directors, Trustees, officers, and employees of the Fund, First
Union Keystone, Keystone, and certain of their affiliates; (2) registered
representatives of firms with dealer agreements with the Principal Underwriter;
and (3) a bank or trust company acting as a trustee for a single account. For
more details, see the statement of additional information.

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

    You may redeem Fund shares for cash at the redemption value by writing to
the Fund, c/o Evergreen Keystone Service Company, Box 2121, Boston,
Massachusetts 02106-2121, and presenting a properly endorsed share certificate
(if certificates have been issued) to the Fund. Your signature(s) on the written
order and certificates must be guaranteed, as described below.

  You may also redeem your shares through your broker-dealer. The Principal
Underwriter, acting as agent for the Fund, stands ready to repurchase Fund
shares upon orders from broker-dealers and will calculate the net asset value on
the same terms as those orders for the purchase of shares received from
broker-dealers and described under "How to Buy Shares." If the Principal
Underwriter has received proper documentation, it will pay the redemption
proceeds, less any applicable CDSC, to the broker-dealer placing the order
within seven days thereafter. The Principal Underwriter charges no fee for this
service. Your broker-dealer, however, may charge a service fee.

  The redemption value equals the net asset value adjusted for fractions of a
cent and may be more or less than your cost depending upon changes in the value
of the Fund's portfolio securities between purchase and redemption. The Fund may
impose a CDSC at the time of redemption of certain shares as explained in "How
to Buy Shares." If imposed, the Fund deducts the CDSC from the redemption
proceeds otherwise payable to you.

REDEMPTION OF SHARES IN GENERAL
  At various times, the Fund may be requested to redeem shares for which it has
not yet received good payment. In such a case, the Fund will mail the redemption
proceeds upon clearance of the purchase check, which may take up to 15 days. Any
delay may be avoided by purchasing shares with a certified check, by Federal
Reserve or bank wire of funds, by direct deposit or by EFT. Although the mailing
of a redemption check may be delayed, the redemption value will be determined
and the redemption processed in the ordinary course of business upon receipt of
proper documentation. In such a case, after redemption and prior to the release
of the proceeds, no appreciation or depreciation will occur in the value of the
redeemed shares, and no interest will be paid on the redemption proceeds. If the
payment of a redemption has been delayed, the check will be mailed or the
proceeds wired or sent EFT promptly after good payment has been collected.

  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
of the amount due on redemption, less any applicable CDSC, will be made within
seven days thereafter, except as discussed herein.

  For your protection, SIGNATURES ON CERTIFICATES, STOCK POWERS AND ALL WRITTEN
ORDERS OR AUTHORIZATIONS MUST BE 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 EKSC'S POLICIES. The Fund and EKSC may waive this
requirement or require additional documents in certain cases. Currently, the
requirement for a signature guarantee has been waived on redemptions of $50,000
or less where the account address of record has been the same for a minimum
period of 30 days. The Fund and EKSC reserve the right to withdraw this waiver
at any time.

  If the Fund receives a redemption or repurchase order, but you have not
clearly indicated the amount of money or number of shares involved, the Fund
cannot execute the order. In such cases, the Fund will request the missing
information from you and process the order on the day such information is
received.

TELEPHONE REDEMPTIONS
  Under ordinary circumstances, you may redeem up to $50,000 from your account
by calling toll free 1-800-343-2898. As mentioned above, to engage in telephone
transactions generally, you must complete the appropriate sections of the
application.

  In order to insure that instructions received by EKSC are genuine when you
initiate a telephone transaction, you will be asked to verify certain criteria
specific to your account. At the conclusion of the transaction, you will be
given a transaction number confirming your request. Written confirmation of your
transaction will be mailed the next business day. Your telephone instructions
will be recorded. Redemptions by telephone are allowed only if the address and
bank account of record have been the same for a minimum period of 30 days.

  If you cannot reach the Fund by telephone, you should follow the procedures
for redeeming by mail or through a broker-dealer as set forth above.

SMALL ACCOUNTS
  Because of the high cost of maintaining small accounts, the Fund reserves the
right to redeem your account if its value has fallen below $1,000, the current
minimum investment level, as a result of your redemptions (but not as a result
of market action). You will be notified in writing and allowed 60 days to
increase the value of your account to the minimum investment level. No CDSCs are
applied to such redemptions.

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, and to impose fees.

  Except as otherwise noted, neither the Fund, EKSC, nor the Principal
Underwriter assumes responsibility for the authenticity of any instructions
received by any of them from a shareholder over the Keystone Automated Response
Line ("KARL"), or by telephone. EKSC will employ reasonable procedures to
confirm that instructions received over KARL or by telephone are genuine.
Neither the Fund, EKSC, nor the Principal Underwriter will be liable when
following instructions received over KARL or by telephone that EKSC reasonably
believes to be genuine.

  The Fund may temporarily suspend the right to redeem its shares when (1) the
Exchange is closed, other than customary weekend and holiday closings; (2)
trading on the Exchange is restricted; (3) 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 EKSC by writing or by
calling toll free 1-800-343-2898.

KEYSTONE AUTOMATED RESPONSE LINE
  KARL offers shareholders specific fund account information and price and yield
quotations as well as the ability to effect account transactions, including
investments, exchanges, and redemptions. Shareholders may access KARL by dialing
toll free 1-800-346-3858 on any touch-tone telephone, 24 hours a day, seven days
a week.

EXCHANGES
  If you have obtained the appropriate prospectus, you may exchange shares of
the Fund for shares of any of the other funds in the Keystone Classic Fund
Family, on the basis of their respective net asset values, by calling toll free
1-800-343-2898 or by writing to Evergreen Keystone Service Company at P.O. Box
2121, Boston, Massachusetts 02106-2121. (See "How to Redeem Shares" for
additional information with respect to telephone transactions.)

  Fund shares purchased by check may be exchanged for shares of any of the funds
in the Keystone Classic Fund Family, other than Keystone Precious Metals
Holdings, Inc. ("KPMH"). In order to exchange Fund shares for shares of KPMH, a
shareholder must have held Fund shares for a period of at least six months. All
exchanges may be made without a fee. If the shares being tendered for exchange
have been held for less than four years and are still subject to a deferred
sales charge, such charge will carry over to the shares being acquired in the
exchange transaction. The Fund reserves the right to terminate this exchange
offer or to change its terms, including the right to charge for any exchange,
upon notice to shareholders pursuant to applicable law.

  Orders to exchange shares of the Fund for shares of Keystone Liquid Trust
("KLT") will be executed by redeeming the shares of the Fund and purchasing
shares of KLT at the net asset value of KLT shares determined after the proceeds
from such redemption become available, which may be up to seven days after such
redemption. In all other cases, orders for exchanges received by the Fund prior
to 4:00 p.m. (eastern time) on any business day will be executed at the
respective net asset values determined as of the close of the next business day.
Orders for exchanges received after 4:00 p.m. (eastern time) on any business day
will be executed at the respective net asset values determined at the close of
the next business day.

  An excessive number of exchanges may be disadvantageous to the Fund.
Therefore, the Fund, in addition to its right to reject any exchange, reserves
the right to terminate the exchange privilege of any shareholder who makes more
than five exchanges of shares of the funds in a year or three in a calendar
quarter.

  An exchange order must comply with the requirements for a redemption or
repurchase order and must specify the dollar value or number of shares to be
exchanged. Exchanges are subject to the minimum initial purchase requirements of
the fund being acquired. An exchange constitutes a sale for federal income tax
purposes.

  The exchange privilege is available only in states where shares of the fund
being acquired may legally be sold.

RETIREMENT PLANS
  The Fund has various retirement plans available to investors, including
Individual Retirement Accounts (IRAs); Rollover IRAs; Simplified Employee
Pension Plans (SEPs); Salary Reduction Plans (SARSEPs); Tax Sheltered Annuity
Plans (TSAs); 403(b)(7) Plans; 401(k) Plans; Keogh Plans; Corporate Profit-
Sharing Plans; and Money Purchase Pension Plans. For details, including fees and
application forms, call EKSC toll free at 1-800-247-4075 or write to KIRC at
P.O. Box 2121, Boston, Massachusetts 02106-2121.

AUTOMATIC INVESTMENT PLAN
  With an Automatic Investment Plan, you can automatically transfer as little as
$100 per month or quarter from your bank account or KLT to the Keystone fund of
your choice. Your bank account will be debited for each transfer. You will
receive confirmation with your next account statement.

  To establish or terminate an Automatic Investment Plan or to change the amount
or schedule of your automatic investments, you may write to or call EKSC. Please
include your account numbers. Termination of an Automatic Investment Plan may
take up to 30 days.

SYSTEMATIC INCOME PLAN
  Under a Systematic Income Plan, shareholders may arrange for regular monthly
or quarterly fixed withdrawal payments. Each payment must be at least $100 and
may be as much as 1% per month or 3% per quarter of the total net asset value of
the Fund shares in the shareholder's account when the Systematic Income Plan is
opened. Fixed withdrawal payments are not subject to a CDSC. Excessive
withdrawals may decrease or deplete the value of a shareholder's account.

OTHER SERVICES
  Under certain circumstances shareholders may, within 30 days after a
redemption, reinstate their accounts at current net asset value.

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

  From time to time, the Fund may advertise "total return" and "current yield."
BOTH FIGURES ARE BASED ON HISTORICAL EARNINGS. PAST PERFORMANCE SHOULD NOT BE
CONSIDERED REPRESENTATIVE OF RESULTS FOR ANY FUTURE PERIOD OF TIME. Total return
refers to the Fund's average annual compounded rates of return over specified
periods determined by comparing the initial amount invested 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. The deduction of the contingent deferred
sales charge is reflected in the applicable years.

  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.

  The Fund may include comparative performance information in advertising or
marketing the Fund's shares, such as data from Lipper Analytical Services, Inc.,
Morningstar, Inc., Standard & Poor's Corporation, Ibbotson Associates or
other industry publications.

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

  The Fund currently issues one class of shares, which participate equally in
dividends and distributions and have equal voting, liquidation and other rights.
When issued and paid for, the shares will be fully paid and nonassessable by the
Fund. Shares may be exchanged as explained under "Shareholder Services," but
will have no other preference, conversion, exchange, or preemptive rights.
Shareholders are entitled to one vote for each full share owned and fractional
votes for fractional shares. Shares are redeemable, transferable, and freely
assignable as collateral. There are no sinking fund provisions. The Fund may
establish additional classes or series of shares.

  The Fund does not have annual meetings. The Fund will have special meetings
from time to time as required under its Restatement of Trust Agreement (the
"Trust Agreement") and under the 1940 Act. As provided in the Fund's Trust
Agreement, 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 for
the purpose of removing a Trustee. The Fund is prepared to assist shareholders
in communications with one another for the purpose of convening such a meeting
as prescribed by Section 16(c) of the 1940 Act.

- ------------------------------------------------------------------------------
ADDITIONAL INFORMATION
- ------------------------------------------------------------------------------

  When the Fund determines from its records that more than one account in the
Fund is registered in the name of a shareholder or shareholders having the same
address, upon written notice to those shareholders, the Fund intends, when an
annual report or semi-annual report of the Fund is required to be furnished, to
mail one copy of such report to that address.

  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
- ------------------------------------------------------------------------------

                 DESCRIPTION OF CERTAIN TYPES OF INVESTMENTS
               AND INVESTMENT TECHNIQUES AVAILABLE TO THE FUND

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

CORPORATE BOND RATINGS
  Higher yields are usually available on securities that are lower rated or that
are unrated. Bonds rated Baa by Moody's are considered as medium grade
obligations, which are neither highly protected nor poorly secured. Debt rated
BBB by S&P is regarded as having an adequate capacity to pay interest and repay
principal, although adverse economic conditions are more likely to lead to a
weakened capacity to pay interest and repay principal for debt in this category
than in higher rated categories. Lower rated securities are usually defined as
Baa or lower by Moody's or BBB or lower by S&P. The Fund may purchase unrated
securities, which are not necessarily of lower quality than rated securities but
may not be attractive to as many buyers. Debt rated BB, B, CCC, CC and C by S&P
is regarded, on balance, as predominantly speculative with respect to capacity
to pay interest and repay principal in accordance with the terms of the
obligation. BB indicates the lowest degree of speculation and C the highest
degree of speculation. While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions. Debt rated CI by S&P is debt (income
bonds) on which no interest is being paid. Debt rated D by S&P is in default and
payment of interest and/or repayment of principal is in arrears. The Fund
intends to invest in D-rated debt only in cases where, in Keystone's judgment,
there is a distinct prospect of improvement in the issuer's financial position
as a result of the completion of reorganization or otherwise. Bonds that are
rated Caa by Moody's are of poor standing. Such issues may be in default or
there may be present elements of danger with respect to principal or interest.
Bonds that are rated Ca by Moody's represent obligations that are speculative in
a high degree. Such issues are often in default or have other market
shortcomings. Bonds that are rated C by Moody's are the lowest rated class of
bonds, and issues so rated can be regarded as having extremely poor prospects of
ever attaining any real investment standing.

ZERO COUPON BONDS
  A zero coupon "stripped" bond represents ownership in serially maturing
interest payments or principal payments on specific underlying notes and bonds,
including coupons relating to such notes and bonds. The interest and principal
payments are direct obligations of the issuer. Coupon zero coupon bonds of any
series mature periodically from the date of issue of such series through the
maturity date of the securities related to such series. Principal zero coupon
bonds mature on the date specified therein, which is the final maturity date of
the related securities. Each zero coupon bond entitles the holder to receive a
single payment at maturity. There are no periodic interest payments on a zero
coupon bond. Zero coupon bonds are offered at discounts from their face amounts.

  In general, owners of zero coupon bonds have substantially all the rights and
privileges of owners of the underlying coupon obligations or principal
obligations. Owners of zero coupon bonds have the right upon default on the
underlying coupon obligations or principal obligations to proceed directly and
individually against the issuer and are not required to act in concert with
other holders of zero coupon bonds.

  For federal income tax purposes, a purchaser of principal zero coupon bonds or
coupon zero coupon bonds (either initially or in the secondary market) is
treated as if the buyer had purchased a corporate obligation issued on the
purchase date with an original issue discount equal to the excess of the amount
payable at maturity over the purchase price. The purchaser is required to take
into income each year as ordinary income an allocable portion of such discounts
determined on a "constant yield" method. Any such income increases the holder's
tax basis for the zero coupon bond, and any gain or loss on a sale of the zero
coupon bonds relative to the holder's basis, as so adjusted, is a capital gain
or loss. If the holder owns both principal zero coupon bonds and coupon zero
coupon bonds representing interest in the same underlying issue of securities, a
special basis allocation rule (requiring the aggregate basis to be allocated
among the items sold and retained based on their relative fair market value at
the time of sale) may apply to determine the gain or loss on a sale of any such
zero coupon bonds.

PAYMENT-IN-KIND SECURITIES
  Payment-in-kind securities pay interest in either cash or additional
securities, at the issuer's option, for a specified period. The issuer's option
to pay in additional securities typically ranges from one to six years, compared
to an average maturity for all PIK securities of eleven years. Call protection
and sinking fund features are comparable to those offered on traditional debt
issues.

  PIKs, like zero coupon bonds, are designed to give an issuer flexibility in
managing cash flow. Several PIKs are senior debt. In other cases, where PIKs are
subordinated, most senior lenders view them as equity equivalents.

  An advantage of PIKs for the issuer -- as with zero coupon securities -- is
that interest payments are automatically compounded (reinvested) at the stated
coupon rate, which is not the case with cash-paying securities. However, PIKs
are gaining popularity over zeros since interest payments in additional
securities can be monetized and are more tangible than accretion of a discount.

  As a group, PIK bonds trade flat (i.e., without accrued interest). Their price
is expected to reflect an amount representing accreted interest since the last
payment. PIKs generally trade at higher yields than comparable cash- paying
securities of the same issuer. Their premium yield is the result of the lesser
desirability of non-cash interest, the more limited audience for non-cash paying
securities, and the fact that many PIKs have been issued to equity investors who
do not normally own or hold such securities.

  Calculating the true yield on a PIK security requires a discounted cash flow
analysis if the security (ex interest) is trading at a premium or a discount
because the realizable value of additional payments is equal to the current
market value of the underlying security, not par.

  Regardless of whether PIK securities are senior or deeply subordinated,
issuers are highly motivated to retire them because they are usually their most
costly form of capital.

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

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

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

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 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.

"WHEN ISSUED" AND "FORWARD COMMITMENT" TRANSACTIONS
  The Fund may also purchase securities on a when issued or delayed delivery
basis and may purchase or sell securities on a forward commitment basis. When
issued and delayed delivery transactions arise when securities are purchased by
the Fund with payment and delivery taking place in the future in order to secure
what is considered to be an advantageous price and yield to the Fund at the time
of purchase. A forward commitment transaction is an agreement by the Fund to
purchase or sell securities at a specified future date. The Fund may also enter
into foreign currency forward contracts which are described in more detail in
the section of this Exhibit entitled "Foreign Currency Transactions." When the
Fund engages in these transactions, the Fund relies on the buyer or seller, as
the case may be, to consummate the sale. Failure to do so may result in the Fund
missing the opportunity to obtain a price or yield considered to be
advantageous. When issued, delayed delivery and forward commitment transactions
may be expected to occur a month or more before delivery is due. However, no
payment or delivery is made by the Fund until it receives payment or delivery
from the other party to the transaction. The Securities and Exchange Commission
has established certain requirements to assure that a Fund is able to meet its
obligations under these contracts, for example a separate account of liquid
assets equal to the value of such purchase commitments may be maintained until
payment is made. When issued, delayed delivery and firm commitment transactions
are subject to risks from changes in value based upon changes in the level of
interest rates, currency rates and other market factors, both before and after
delivery. The Fund does not accrue any income on such securities or currencies
prior to their delivery. To the extent the Fund engages in any of these
transactions, it will do so for the purpose of acquiring portfolio securities or
currencies consistent with its investment objective and policies and not for the
purpose of investment leverage. The Fund currently does not intend to invest
more than 5% of its assets in when issued or delayed delivery transactions.

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

DERIVATIVES
  The Fund may use derivatives in furtherance of its investment objective.
Derivatives are financial contracts whose value depends on, or is derived from,
the value of an underlying asset, reference rate or index. These assets, rates,
and indices may include bonds, stocks, mortgages, commodities, interest rates,
currency exchange rates, bond indices, and stock indices. Derivatives can be
used to earn income or protect against risk, or both. For example, one party
with unwanted risk may agree to pass that risk to another party who is willing
to accept the risk, the second party being motivated, for example, by the desire
either to earn income in the form of a fee or premium from the first party, or
to reduce its own unwanted risk by attempting to pass all or part of that risk
to the first party.

  Derivatives can be used by investors, such as the Fund, to earn income and
enhance returns, to hedge or adjust the risk profile of the portfolio, and
either in place of more traditional direct investments or to obtain exposure to
otherwise inaccessible markets. The Fund is permitted to use derivatives for one
or more of these purposes. The use of derivatives for non-hedging purposes
entails greater risks than if derivatives were used solely for hedging purposes.
The Fund uses futures contracts and related options as well as forwards for
hedging purposes. Derivatives are a valuable tool, which, when used properly,
can provide significant benefit to Fund shareholders. Keystone is not an
aggressive user of derivatives with respect to the Fund. However, the Fund may
take positions in those derivatives that are within its investment policies if,
in Keystone's judgment, this represents an effective response to current or
anticipated market conditions. Keystone's use of derivatives is subject to
continuous risk assessment and control from the standpoint of the Fund's
investment objective and policies.

  Derivatives may be (1) standardized, exchange-traded contracts or (2)
customized, privately negotiated contracts. Exchange-traded derivatives tend to
be more liquid and subject to less credit risk than those that are privately
negotiated.

  There are four principal types of derivative instruments--options, futures,
forwards, and swaps--from which virtually any type of derivative transaction can
be created. Further information regarding options, futures, forwards, and swaps,
is provided later in this section and is provided in the Fund's statement of
additional information.

  Debt instruments that incorporate one or more of these building blocks for the
purpose of determining the principal amount of and/or rate of interest payable
on the debt instruments are often referred to as "structured securities." An
example of this type of structured security is indexed commercial paper. The
term is also used to describe certain securities issued in connection with the
restructuring of certain foreign obligations. See "Indexed Commercial Paper" and
"Structured Securities" below. The term "derivative" is also sometimes used to
describe securities involving rights to a portion of the cash flows from an
underlying pool of mortgages or other assets from which payments are passed
through to the owner of, or that collateralize, the securities. See "Mortgage
Related Securities," "Collateralized Mortgage Obligations," "Adjustable Rate
Mortgage Securities," "Stripped Mortgage Securities," "Mortgage Securities -
Special Considerations," and "Other Asset-Backed Securities" and the Fund's
statement of additional information.

  While the judicious use of derivatives by experienced investment managers,
such as Keystone, can be beneficial, derivatives also involve risks different
from, and, in certain cases, greater than, the risks presented by more
traditional investments. Following is a general discussion of important risk
factors and issues concerning the use of derivatives that investors should
understand before investing in the Fund.

o Market Risk -- This is the general risk attendant to all investments that the
  value of a particular investment will decline or otherwise change in a way
  detrimental to the Fund's interest.

o Management Risk -- Derivative products are highly specialized instruments that
  require investment techniques and risk analyses different from those
  associated with stocks and bonds. The use of a derivative requires an
  understanding not only of the underlying instrument, but also of the
  derivative itself, without the benefit of observing the performance of the
  derivative under all possible market conditions. In particular, the use and
  complexity of derivatives require the maintenance of adequate controls to
  monitor the transactions entered into, the ability to assess the risk that a
  derivative adds to the Fund's portfolio and the ability to forecast price,
  interest rate or currency exchange rate movements correctly.

o Credit Risk -- This is the risk that a loss may be sustained by the Fund as a
  result of the failure of another party to a derivative (usually referred to as
  a "counterparty") to comply with the terms of the derivative contract. The
  credit risk for exchange-traded derivatives is generally less than for
  privately negotiated derivatives, since the clearing house, which is the
  issuer or counterparty to each exchange-traded derivative, provides a
  guarantee of performance. This guarantee is supported by a daily payment
  system (i.e., margin requirements) operated by the clearing house in order to
  reduce overall credit risk. For privately negotiated derivatives, there is no
  similar clearing agency guarantee. Therefore, the Fund considers the
  creditworthiness of each counterparty to a privately negotiated derivative in
  evaluating potential credit risk.

o Liquidity Risk -- Liquidity risk exists when a particular instrument is
  difficult to purchase or sell. If a derivative transaction is particularly
  large or if the relevant market is illiquid (as is the case with many
  privately negotiated derivatives), it may not be possible to initiate a
  transaction or liquidate a position at an advantageous price.

o Leverage Risk -- Since many derivatives have a leverage component, adverse
  changes in the value or level of the underlying asset, rate or index can
  result in a loss substantially greater than the amount invested in the
  derivative itself. In the case of swaps, the risk of loss generally is related
  to a notional principal amount, even if the parties have not made any initial
  investment. Certain derivatives have the potential for unlimited loss,
  regardless of the size of the initial investment.

o Other Risks -- Other risks in using derivatives include the risk of mispricing
  or improper valuation and the inability of derivatives to correlate perfectly
  with underlying assets, rates, and indices. Many derivatives, in particular
  privately negotiated derivatives, are complex and often valued subjectively.
  Improper valuations can result in increased cash payment requirements to
  counterparties or a loss of value to the Fund. Derivatives do not always
  perfectly or even highly correlate or track the value of the assets, rates or
  indices they are designed to closely track. Consequently, the Fund's use of
  derivatives may not always be an effective means of, and sometimes could be
  counterproductive to, furthering the Fund's investment objective.

OPTIONS TRANSACTIONS
  WRITING COVERED OPTIONS. The Fund may write (i.e., sell) covered call and put
options. By writing a call option, the Fund becomes obligated during the term of
the option to deliver the securities underlying the option upon payment of the
exercise price. By writing a put option, the Fund becomes obligated during the
term of the option to purchase the securities underlying the option at the
exercise price if the option is exercised. The Fund also may write straddles
(combinations of covered puts and calls on the same underlying security).

  The Fund may only write "covered" options. This means that so long as the Fund
is obligated as the writer of a call option it will own the underlying
securities subject to the option or, in the case of call options on U.S.
Treasury bills, the Fund might own substantially similar U.S. Treasury bills. If
the Fund has written options against all of its securities that are available
for writing options, the Fund may be unable to write additional options unless
it sells a portion of its portfolio holdings to obtain new securities against
which it can write options. If this were to occur, higher portfolio turnover and
correspondingly greater brokerage commissions and other transaction costs may
result. The Fund does not expect, however, that this will occur.

  The Fund will be considered "covered" with respect to a put option it writes
if, so long as it is obligated as the writer of the put option, it deposits and
maintains with its custodian in a segregated account liquid assets having a
value equal to or greater than the exercise price of the option.

  The principal reason for writing call or put options is to obtain, through a
receipt of premiums, a greater current return than would be realized on the
underlying securities alone. The Fund receives a premium from writing a call or
put option, which it retains whether or not the option is exercised. By writing
a call option, the Fund might lose the potential for gain on the underlying
security while the option is open, and, by writing a put option, the Fund might
become obligated to purchase the underlying security for more than its current
market price upon exercise.

  PURCHASING OPTIONS. The Fund may purchase put or call options, including put
or call options for the purpose of offsetting previously written put or call
options of the same series.

  If the Fund is unable to effect a closing purchase transaction with respect to
covered options it has written, the Fund will not be able to sell the underlying
securities or dispose of assets held in a segregated account until the options
expire or are exercised.

  An option position may be closed out only in a secondary market for an option
of the same series. Although the Fund generally will write only those options
for which there appears to be an active secondary market, there is no assurance
that a liquid secondary market will exist for any particular option at any
particular time, and, for some options, no secondary market may exist. In such
event, it might not be possible to effect a closing transaction in a particular
option.

  Options on some securities are relatively new, and it is impossible to predict
the amount of trading interest that will exist in such options. There can be no
assurance that viable markets will develop or continue. The failure of such
markets to develop or continue could significantly impair the Fund's ability to
use such options to achieve its investment objective.

OPTIONS TRADING MARKETS. Options in which the Fund will trade are generally
listed on national securities exchanges. Exchanges on which such options
currently are traded include the Chicago Board Options Exchange and the New
York, American, Pacific, and Philadelphia Stock Exchanges. Options on some
securities may not be listed on any exchange, but traded in the over-the-counter
market. Options traded in the over-the-counter market involve the additional
risk that securities dealers participating in such transactions could fail to
meet their obligations to the Fund. The use of options traded in the
over-the-counter market may be subject to limitations imposed by certain state
securities authorities. In addition to the limits on its use of options
discussed herein, the Fund is subject to the investment restrictions described
in this prospectus and in the statement of additional information.

  The staff of the Securities and Exchange Commission is of the view that the
premiums that the Fund pays for the purchase of unlisted options and the value
of securities used to cover unlisted options written by the Fund are considered
to be invested in illiquid securities or assets for the purpose of calculating
whether the Fund is in compliance with its policies on illiquid securities.

FUTURES TRANSACTIONS
  The Fund may enter into currency and other financial futures contracts and
write options on such contracts. The Fund intends to enter into such contracts
and related options for hedging purposes. The Fund will enter into securities,
currency or index-based futures contracts in order to hedge against changes in
interest or exchange rates or securities prices. A futures contract on
securities or currencies is an agreement to buy or sell securities or currencies
at a specified price during a designated month. A futures contract on a
securities index does not involve the actual delivery of securities, but merely
requires the payment of a cash settlement based on changes in the securities
index. The Fund does not make payment or deliver securities upon entering into a
futures contract. Instead, it puts down a margin deposit, which is adjusted to
reflect changes in the value of the contract and which continues until the
contract is terminated.

  The Fund may sell or purchase futures contracts. When a futures contract is
sold by the Fund, the value of the contract will tend to rise when the value of
the underlying securities or currencies declines and to fall when the value of
such securities or currencies increases. Thus, the Fund sells futures contracts
in order to offset a possible decline in the value of its securities or
currencies. If a futures contract is purchased by the Fund, the value of the
contract will tend to rise when the value of the underlying securities or
currencies increases and to fall when the value of such securities or currencies
declines. The Fund intends to purchase futures contracts in order to establish
what is believed by Keystone to be a favorable price and rate of return for
securities or favorable exchange rate for currencies the Fund intends to
purchase.

  The Fund also intends to purchase put and call options on futures contracts
for hedging purposes. A put option purchased by the Fund would give it the right
to assume a position as the seller of a futures contract. A call option
purchased by the Fund would give it the right to assume a position as the
purchaser of a futures contract. The purchase of an option on a futures contract
requires the Fund to pay a premium. In exchange for the premium, the Fund
becomes entitled to exercise the benefits, if any, provided by the futures
contract, but is not required to take any action under the contract. If the
option cannot be exercised profitably before it expires, the Fund's loss will be
limited to the amount of the premium and any transaction costs.

  The Fund may enter into closing purchase and sale transactions in order to
terminate a futures contract and may sell put and call options for the purpose
of closing out its options positions. The Fund's ability to enter into closing
transactions depends on the development and maintenance of a liquid secondary
market. There is no assurance that a liquid secondary market will exist for any
particular contract or at any particular time. As a result, there can be no
assurance that the Fund will be able to enter into an offsetting transaction
with respect to a particular contract at a particular time. If the Fund is not
able to enter into an offsetting transaction, the Fund will continue to be
required to maintain the margin deposits on the contract and to complete the
contract according to its terms, in which case, it would continue to bear market
risk on the transaction.

  Although futures and related options transactions are intended to enable the
Fund to manage market, interest rate or exchange rate risk, unanticipated
changes in interest rates, exchange rates or market prices could result in
poorer performance than if it had not entered into these transactions. Even if
Keystone correctly predicts interest or exchange rate movements, a hedge could
be unsuccessful if changes in the value of the Fund's futures position did not
correspond to changes in the value of its investments. This lack of correlation
between the Fund's futures and securities or currencies positions may be caused
by differences between the futures and securities or currencies markets or by
differences between the securities or currencies underlying the Fund's futures
position and the securities or currencies held by or to be purchased for the
Fund. Keystone will attempt to minimize these risks through careful selection
and monitoring of the Fund's futures and options positions.

  The Fund does not intend to use futures transactions for speculation or
leverage. The Fund has the ability to write options on futures, but intends to
write such options only to close out options purchased by the Fund. The Fund
will not change these policies without supplementing the information in its
prospectus and statement of additional information.

FOREIGN CURRENCY TRANSACTIONS
  As discussed above, the Fund may invest in securities of foreign issuers. When
the Fund invests in foreign securities, they usually will be denominated in
foreign currencies, and the Fund temporarily may hold funds in foreign
currencies. Thus, the value of Fund shares will be affected by changes in
exchange rates.

  As one way of managing exchange rate risk, in addition to entering into
currency futures contracts, the Fund may enter into forward currency exchange
contracts (agreements to purchase or sell currencies at a specified price and
date). The exchange rate for the transaction (the amount of currency the Fund
will deliver or receive when the contract is completed) is fixed when the Fund
enters into the contract. The Fund usually will enter into these contracts to
stabilize the U.S. dollar value of a security it has agreed to buy or sell. The
Fund intends to use these contracts to hedge the U.S. dollar value of a security
it already owns, particularly if the Fund expects a decrease in the value of the
currency in which the foreign security is denominated. Although the Fund will
attempt to benefit from using forward contracts, the success of its hedging
strategy will depend on Keystone's ability to predict accurately the future
exchange rates between foreign currencies and the U.S. dollar. The value of the
Fund's investments denominated in foreign currencies will depend on the relative
strength of those currencies and the U.S. dollar, and the Fund may be affected
favorably or unfavorably by changes in the exchange rates or exchange control
regulations between foreign currencies and the U.S. dollar. Changes in foreign
currency exchange rates also may affect the value of dividends and interest
earned, gains and losses realized on the sale of securities and net investment
income and gains, if any, to be distributed to shareholders by the Fund.
Although the Fund does not currently intend to do so, the Fund may also purchase
and sell options related to foreign currencies. The Fund does not intend to
enter into foreign currency transactions for speculation or leverage.

INTEREST RATE TRANSACTIONS (SWAPS, CAPS, AND FLOORS). If the Fund enters into
interest rate swap, cap or floor transactions, it expects to do so primarily for
hedging purposes, which may include preserving a return or spread on a
particular investment or portion of its portfolio or protecting against an
increase in the price of securities the Fund anticipates purchasing at a later
date. The Fund does not currently intend to use these transactions in a
speculative manner.

  Interest rate swaps involve the exchange by the Fund with another party of
their respective commitments to pay or receive interest (e.g., an exchange of
floating rate payments for fixed rate payments). Interest rate caps and floors
are similar to options in that the purchase of an interest rate cap or floor
entitles the purchaser, to the extent that a specified index exceeds (in the
case of a cap) or falls below (in the case of a floor) a predetermined interest
rate, to receive payments of interest on a contractually-based principal
("notional") amount from the party selling the interest rate cap or floor. The
Fund may enter into interest rate swaps, caps, and floors on either an
asset-based or liability-based basis, depending upon whether it is hedging its
assets or liabilities, and will usually enter into interest rate swaps on a net
basis (i.e., the two payment streams are netted out, with the Fund receiving or
paying, as the case may be, only the net amount of the two payments).

  The swap market has grown substantially in recent years, with a large number
of banks and investment banking firms acting as principals and as agents
utilizing standardized swap documentation. As a result, the swap market has
become more established and relatively liquid. Caps and floors are less liquid
than swaps. These transactions also involve the delivery of securities or other
underlying assets and principal. Accordingly, the risk of loss to the Fund from
interest rate transactions is limited to the net amount of interest payments
that the Fund is contractually obligated to make.

INDEXED COMMERCIAL PAPER. Indexed commercial paper may have its principal linked
to changes in foreign currency exchange rates whereby its principal amount is
adjusted upwards or downwards (but not below zero) at maturity to reflect
changes in the referenced exchange rate. If permitted by its investment
policies, the Fund will purchase such commercial paper with the currency in
which it is denominated and, at maturity, will receive interest and principal
payments thereon in that currency, but the amount of principal payable by the
issuer at maturity will change in proportion to the change (if any) in the
exchange rate between the two specified currencies between the date the
instrument is issued and the date the instrument matures. While such commercial
paper entails the risk of loss of principal, the potential for realizing gains
as a result of changes in foreign currency exchange rates enables the Fund to
hedge (or cross-hedge) against a decline in the U.S. dollar value of investments
denominated in foreign currencies while providing an attractive money market
rate of return.

MORTGAGE-RELATED SECURITIES. The mortgage-related securities in which the Fund
may invest typically are securities representing interests in pools of mortgage
loans made to home owners. Mortgage-related securities bear interest at either a
fixed rate or an adjustable rate determined by reference to an index rate. The
mortgage loan pools may be assembled for sale to investors (such as the Fund) by
governmental or private organizations. Mortgage-related securities issued by the
Government National Mortgage Association ("GNMA") are backed by the full faith
and credit of the U.S. government; those issued by Federal National Mortgage
Associated ("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC") are not
so backed.

  Securities representing interests in pools created by private issuers
generally offer a higher rate of interest than securities representing interests
in pools created by governmental issuers because there are no direct or indirect
governmental guarantees of the underlying mortgage payments. However, private
issuers sometimes obtain committed loan facilities, lines of credit, letters of
credit, surety bonds or other forms of liquidity and credit enhancement to
support the timely payment of interest and principal with respect to their
securities if the borrowers on the underlying mortgages fail to make their
mortgage payments. The ratings of such non-governmental securities are generally
dependent upon the ratings of the providers of such liquidity and credit support
and would be adversely affected if the rating of such an enhancer were
downgraded. The Fund may buy mortgage-related securities without credit
enhancement if the securities meet the Fund's investment standards. Although the
market for mortgage-related securities is becoming increasingly liquid, those of
certain private organizations may not be readily marketable.

  One type of mortgage-related security is of the "pass-through" variety. The
holder of a pass-through security is considered to own an undivided beneficial
interest in the underlying pool of mortgage loans and receives a pro rata share
of the monthly payments made by the borrowers on their mortgage loans, net of
any fees paid to the issuer or guarantor of the securities. Prepayments of
mortgages resulting from the sale, refinancing or foreclosure of the underlying
properties are also paid to the holders of these securities. Some
mortgage-related securities, such as securities issued by GNMA, are referred to
as "modified pass-through" securities. The holders of these securities are
entitled to the full and timely payment of principal and interest, net of
certain fees, regardless of whether payments are actually made on the underlying
mortgages. Another form of mortgage-related security is a "pay- through"
security, which is a debt obligation of the issuer secured by a pool of mortgage
loans pledged as collateral that is legally required to be paid by the issuer
regardless of whether payments are actually made on the underlying mortgages.

COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS"). CMOs are the predominant type of
"pay-through" mortgage-related security. CMOs are designed to reduce the risk of
prepayment for investors by issuing multiple classes of securities, each having
different maturities, interest rates and payment schedules, and with the
principal and interest on the underlying mortgages allocated among the several
classes in various ways. The collateral securing the CMOs may consist of a pool
of mortgages, but may also consist of mortgage-backed bonds or pass-through
securities. CMOs may be issued by a U.S. government instrumentality or agency,
or by a private issuer. Although payment of the principal of, and interest on,
the underlying collateral securing privately issued CMOs may be guaranteed by
GNMA, FNMA or FHLMC, these CMOs represent obligations solely of the private
issuer and are not insured or guaranteed by GNMA, FNMA, FHLMC, any other
governmental agency, or any other person or entity.

INVERSE FLOATING RATE COLLATERALIZED MORTGAGE OBLIGATIONS. In addition to
investing in fixed rate and adjustable rate CMOs, the Fund may also invest in
CMOs with rates that move inversely to market rates ("inverse floaters").

  An inverse floater bears an interst rate that resets in the opposite direction
of the change in a specified interest rate index. As market interest rates rise,
the interest rate on the inverse floater goes down, and vice versa. Inverse
floaters tend to exhibit greater price volatility than fixed-rate bonds of
similar maturity and credit quality. The interest rates on inverse floaters may
be significantly reduced, even to zero, if interest rates rise. Moreover, the
secondary market for inverse floaters may be limited in rising interest rate
environments.

ADJUSTABLE RATE MORTGAGE SECURITIES. Another type of mortgage-related security,
known as adjustable-rate mortgage securities ("ARMS"), bears interest at a rate
determined by reference to a predetermined interest rate or index. There are two
main categories of rates or indices: (1) rates based on the yield on U.S.
Treasury securities and (2) indices derived from a calculated measure such as a
cost of funds index or a moving average of mortgage rates. Some rates and
indices closely mirror changes in market interest rate levels, while others tend
to lag changes in market rate levels and tend to be somewhat less volatile.

  ARMS may be secured by adjustable-rate mortgages or fixed-rate mortgages. ARMS
secured by fixed-rate mortgages generally have lifetime caps on the coupon rates
of the securities. To the extent that general interest rates increase faster
than the interest rates on the ARMS, these ARMS will decline in value. The
adjustable-rate mortgages that secure ARMS will frequently have caps that limit
the maximum amount by which the interest rate or the monthly principal and
interest payments on the mortgages may increase. These payment caps can result
in negative amortization (i.e., an increase in the balance of the mortgage
loan). Furthermore, since many adjustable-rate mortgages only reset on an annual
basis, the values of ARMS tend to fluctuate to the extent that changes in
prevailing interest rates are not immediately reflected in the interest rates
payable on the underlying adjustable-rate mortgages.

STRIPPED MORTGAGE SECURITIES. Stripped mortgage-related securities ("SMRS") are
mortgage-related securities that are usually structured with two classes of
securities collateralized by a pool of mortgages or a pool of mortgaged-backed
bonds or pass-through securities, with each class receiving different
proportions of the principal and interest payments from the underlying assets. A
common type of SMRS has one class of interest-only securities ("IOs") receiving
all of the interest payments from the underlying assets, while the other class
of securities, principal-only securities ("POs"), receives all of the principal
payments from the underlying assets. IOs and POs are extremely sensitive to
interest rate changes and are more volatile than mortgage-related securities
that are not stripped. IOs tend to decrease in value as interest rates decrease,
while POs generally increase in value as interest rates decrease. If prepayments
of the underlying mortgages are greater than anticipated, the amount of interest
earned on the overall pool will decrease due to the decreasing principal balance
of the assets. Changes in the values of IOs and POs can be substantial and occur
quickly, such as occurred in the first half of 1994 when the value of many POs
dropped precipitously due to an increase in interest rates. For this reason, the
Fund does not rely on IOs and POs as the principal means of furthering its
investment objective.

MORTGAGE-RELATED SECURITIES -- SPECIAL CONSIDERATIONS. The value of
mortgage-related securities is affected by a number of factors. Unlike
traditional debt securities, which have fixed maturity dates, mortgage-related
securities may be paid earlier than expected as a result of prepayment of the
underlying mortgages. If property owners make unscheduled prepayments of their
mortgage loans, these prepayments will result in the early payment of the
applicable mortgage-related securities. In that event, the Fund may be unable to
invest the proceeds from the early payment of the mortgage-related securities in
an investment that provides as high a yield as the mortgage-related securities.
Consequently, early payment associated with mortgage-related securities causes
these securities to experience significantly greater price and yield volatility
than experienced by traditional fixed-income securities. The occurrence of
mortgage prepayments is affected by the level of general interest rates, general
economic conditions, and other social and demographic factors. During periods of
falling interest rates, the rate of mortgage prepayments tends to increase,
thereby tending to decrease the life of mortgage-related securities. During
periods of rising interest rates, the rate of mortgage prepayments usually
decreases, thereby tending to increase the life of mortgage-related securities.
If the life of a mortgage-related security is inaccurately predicted, the Fund
may not be able to realize the rate of return it expected.

  As with fixed-income securities generally, the value of mortgage-related
securities can also be adversely affected by increases in general interest rates
relative to the yield provided by such securities. Such adverse effect is
especially possible with fixed-rate mortgage securities. If the yield available
on other investments rises above the yield of the fixed-rate mortgage securities
as a result of general increases in interest rate levels, the value of the
mortgage-related securities will decline. Although the negative effect could be
lessened if the mortgage-related securities were to be paid earlier (thus
permitting the Fund to reinvest the prepayment proceeds in investments yielding
the higher current interest rate), as described above the rate of mortgage
prepayments and earlier payment of mortgage-related securities generally tends
to decline during a period of rising interest rates.

  Although the value of ARMS may not be affected by rising interest rates as
much as the value of fixed-rate mortgage securities is affected by rising
interest rates, ARMS may still decline in value as a result of rising interest
rates. Although, as described above, the yield on ARMS varies with changes in
the applicable interest rate or index, there is often a lag between increases in
general interest rates and increases in the yield on ARMS as a result of
relatively infrequent interest rate reset dates. In addition, adjustable-rate
mortgages and ARMS often have interest rate or payment caps that limit the
ability of the adjustable-rate mortgages or ARMS to fully reflect increases in
the general level of interest rates.

OTHER ASSET-BACKED SECURITIES. The securitization techniques used to develop
mortgage-related securities are being applied to a broad range of financial
assets. Through the use of trusts and special purpose corporations, various
types of assets, including automobile loans and leases, credit card receivables,
home equity loans, equipment leases, and trade receivables, are being
securitized in structures similar to the structures used in mortgage
securitizations. These asset-backed securities are subject to risks associated
with changes in interest rates and prepayment of underlying obligations similar
to the risks of investment in mortgage-related securities discussed above.

  Each type of asset-backed security also entails unique risks depending on the
type of assets involved and the legal structure used. For example, credit card
receivables are generally unsecured obligations of the credit card holder and
the debtors are entitled to the protection of a number of state and federal
consumer credit laws, many of which give such debtors the right to set off
certain amounts owed on the credit cards, thereby reducing the balance due.
There have also been proposals to cap the interest rate that a credit card
issuer may charge. In some transactions, the value of the asset-backed security
is dependent on the performance of a third party acting as credit enhancer or
servicer. Furthermore, in some transactions (such as those involving the
securitization of vehicle loans or leases) it may be administratively burdensome
to perfect the interest of the security issuer in the underlying collateral and
the underlying collateral may become damaged or stolen.

VARIABLE, FLOATING, AND LEVERAGED INVERSE FLOATING RATE INSTRUMENTS. Fixed-
income securities may have fixed, variable or floating rates of interest.
Variable and floating rate securities pay interest at rates that are adjusted
periodically, according to a specified formula. A "variable" interest rate
adjusts at predetermined intervals (e.g., daily, weekly or monthly), while a
"floating" interest rate adjusts whenever a specified benchmark rate (such as
the bank prime lending rate) changes.

  The Fund may invest in fixed-income securities that pay interest at a coupon
rate equal to a base rate, plus additional interest for a certain period of time
if short-term interest rates rise above a predetermined level or "cap." The
amount of such an additional interest payment typically is calculated under a
formula based on a short-term interest rate index multiplied by a designated
factor.

  An inverse floater may be considered to be leveraged to the extent that its
interest rate varies by a magnitude that exceeds the magnitude of the change in
the index rate of interest. The higher degree of leverage inherent in inverse
floaters is associated with greater volatility in market value. 

STRUCTURED SECURITIES. Structured securities represent interests in entities
organized and operated solely for the purpose of restructuring the investment
characteristics of sovereign debt obligations or foreign government securities.
This type of restructuring involves the deposit with or purchase by an entity,
such as a corporation or trust, of specified instruments (such as commercial
bank loans or Brady Bonds) and the issuance by that entity of one or more
classes of structured securities backed by, or representing interests in, the
underlying instruments. The cash flow on the underlying instruments may be
apportioned among the newly issued structured securities to create securities
with different investment characteristics such as varying maturities, payment
priorities and interest rate provisions, and the extent of the payments made
with respect to structured securities is dependent on the extent of the cash
flow on the underlying instruments. Because structured securities typically
involve no credit enhancement, their credit risk generally will be equivalent to
that of the underlying instruments. Structured securities of a given class may
be either subordinated or unsubordinated to the right of payment of another
class. Subordinated structured securities typically have higher yields and
present greater risks than unsubordinated structured securities.

BRADY BONDS. Brady Bonds are created through the exchange of existing commercial
bank loans to foreign entities for new obligations in connection with debt
restructurings under a plan introduced by former U.S. Secretary of the Treasury,
Nicholas F. Brady (the "Brady Plan"). Brady Bonds have been issued only
recently, and, accordingly, do not have a long payment history. They may be
collateralized or uncollateralized and issued in various currencies (although
most are U.S. dollar-denominated) and they are actively traded in the
over-the-counter secondary market.

  U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed-rate
par bonds or floating rate discount bonds, are generally collateralized in full
as to principal due at maturity by U.S. Treasury zero coupon obligations that
have the same maturity as the Brady Bonds. Interest payments on these Brady
Bonds generally are collateralized by cash or securities in an amount that, in
the case of fixed rate bonds, is equal to at least one year of rolling interest
payments based on the applicable interest rate at that time and is adjusted at
regular intervals thereafter. Certain Brady Bonds are entitled to "value
recovery payments" in certain circumstances, which in effect constitute
supplemental interest payments, but generally are not collateralized. Brady
Bonds are often viewed as having up to four valuation components: (1)
collateralized repayment of principal at final maturity, (2) collateralized
interest payments, (3) uncollateralized interest payments, and (4) any
uncollateralized repayment of principal at maturity (these uncollateralized
amounts constitute the "residual risk"). In the event of a default with respect
to collateralized Brady Bonds as a result of which the payment obligations of
the issuer are accelerated, the U.S. Treasury zero coupon obligations held as
collateral for the payment of principal will not be distributed to investors,
nor will such obligations be sold and the proceeds distributed. The collateral
will be held by the collateral agent to the scheduled maturity of the defaulted
Brady Bonds, which will continue to be outstanding, at which time the face
amount of the collateral will equal the principal payments that would have then
been due on the Brady Bonds in the normal course. In addition, in light of the
residual risk of Brady Bonds and, among other factors, the history of defaults
with respect to commercial bank loans by public and private entities of
countries issuing Brady Bonds, investments in Brady Bonds are to be viewed as
speculative.

                             INVESTMENT RESTRICTIONS


         None of the  restrictions  enumerated in this  paragraph may be changed
without a vote of the holders of a majority of the Fund's  outstanding 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. The Fund shall not do the following:

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

         (2) make short sales of securities or maintain a short position, unless
at all  times  when a short  position  is open 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;

         (3) borrow money,  except that the Fund may (a) borrow money from banks
for emergency or extraordinary  purposes in aggregate amounts up to one-third of
its net assets, and (b) enter into reverse repurchase agreements;

         (4)  pledge,  mortgage  or  hypothecate  its  assets  except  to secure
indebtedness  permitted by subparagraph (3) above,  with pledged assets to be no
more than 15% of its total assets;

         (5) purchase any security other than United States ("U.S.")  government
securities  of any issuer if as a result more than 25% of its total assets would
be invested in a single industry,  including  industrial  development bonds from
the same  facility  or  similar  types of  facilities;  governmental  issuers of
municipal  bonds are not  regarded  as members of an  industry  and the Fund may
invest more than 25% of its assets in industrial development bonds;

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

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

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

         (9) 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 currency
or other financial futures and related options transactions;

         (10) act as an  underwriter  except to the extent that,  in  connection
with the  disposition  of its portfolio  investments,  it may be deemed to be an
underwriter under federal securities laws; or purchase  securities which are not
readily marketable except for repurchase agreements;

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

         (12) purchase  securities of any issuer if the person  responsible  for
payment,  together  with any  predecessor,  has been in operation  for less than
three years if, as a result,  the aggregate of such investments  would exceed 5%
of the Fund's total assets;  provided,  however, that this restriction shall not
apply to U.S.  government  securities or to any  obligation the payment of which
involves the credit and taxing power of any person authorized to issue municipal
bonds;

         (13) invest in interests in oil, gas or other mineral exploration or
development programs;

         (14)  make  loans,  except  to the  extent  that the  purchase  of debt
instruments  or  repurchase  agreements  may be deemed  to be loans;  repurchase
agreements  maturing  in more than  seven days will not exceed 10% of the Fund's
total assets; and

         (15) purchase securities of foreign issuers.

         The  foregoing  percentage  restrictions  will apply at the time of the
purchase of a security and shall not be considered  violated unless an excess or
deficiency  occurs or exists  immediately after and as a result of a purchase of
such security. For the purpose of Investment  Restrictions (5) and (6), the Fund
will treat each state,  territory and  possession  of the U.S.,  the District of
Columbia  and, if its assets and revenues are separate  from those of the entity
or entities creating it, each political subdivision,  agency and instrumentality
of any one (or more, as in the case of a multistate  authority or agency) of the
foregoing as an issuer of all securities that are backed primarily by its assets
or  revenues;  each  company  as an issuer  of all  securities  that are  backed
primarily by its assets or revenues;  and each of the  foregoing  entities as an
issuer of all securities  that it guarantees;  provided,  however,  that for the
purpose  of  limitation  (6) no  entity  shall be  deemed  to be an  issuer of a
security  that it  guarantees  so long as no more than 10% of the  Fund's  total
assets  (taken at current  value) are invested in  securities  guaranteed by the
entity and securities of which it is otherwise deemed to be an issuer.

         The Fund does not presently intend to invest more than 25% of its total
assets in (1) municipal bonds of a single state and its  subdivisions,  agencies
and  instrumentalities;  of a single territory or possession of the U.S. and its
subdivisions, agencies or instrumentalities;  or of the District of Columbia and
any subdivision,  agency or instrumentality  thereof; or (2) municipal bonds the
payment of which depends on revenues  derived from a single  facility or similar
types of facilities.  Since certain municipal bonds may be related in such a way
that an economic, business or political development or change affecting one such
security could  likewise  affect the other  securities,  a change in this policy
could  result  in  increased   investment  risk,  but  no  change  is  presently
contemplated.  The  Fund  may  invest  more  than  25% of its  total  assets  in
industrial development bonds.

         In  addition,  the Fund will not  issue  senior  securities,  except as
appropriate  to  evidence  indebtedness  which  the Fund is  permitted  to incur
pursuant  to  Investment  Restriction  (3) above and  except  for  shares of any
additional series or portfolios which may be established by the Trustees.

         Notwithstanding the eighth investment  restriction  enumerated above or
any of the other limitations above, the Fund may invest all of its assets in the
securities of a single open-end management investment company with substantially
the same fundamental  investment  objectives,  policies, and restrictions as the
Fund. See "Investment Objective and Policies" in the prospectus.


                             VALUATION OF SECURITIES


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

         Non-tax  exempt  securities  for which  market  quotations  are readily
available  are valued on a consistent  basis at that price  quoted that,  in the
opinion of the Fund's Board of Trustees or the person designated by the Board of
Trustees to make the  determination,  most nearly represents the market value of
the particular security.

         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;  short-term investments maturing in more
than sixty days for which market  quotations are readily available are valued at
current  market value;  and 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 and which,  in any case,  reflects fair
value as determined by the Fund's Board of Trustees.

         Any  securities for which market  quotations are not readily  available
are valued on a consistent basis at fair value as determined in good faith using
methods prescribed by the Fund's Board of Trustees.



                                                     BROKERAGE


Selection of Brokers

         In  effecting  transactions  in  portfolio  securities  for  the  Fund,
Keystone  seeks  the best  execution  of orders  at the most  favorable  prices.
Keystone  determines  whether a broker has provided the Fund with best execution
and price in the  execution of a securities  transaction  by  evaluating,  among
other things:
         1.       overall direct net economic result to the Fund;

         2.       the efficiency with which the transaction is effected;

         3.       the broker's ability to effect the transaction where a large
                  block is involved;

         4.       the broker's readiness to execute potentially difficult
                  transactions in the future;

         5.       the financial strength and stability of the broker; and

         6.       the receipt of research services,  such as analyes and reports
                  concerning issuers, industries,  securities,  economic factors
                  and  trends  and other  statistical  and  factual  information
                  ("research services.")

         The Fund's  management  weighs these  considerations in determining the
overall reasonableness of the brokerage commissions paid.

         Should the Fund or Keystone  receive  research  services from a broker,
the Fund would  consider such services to be in addition to, and not in lieu of,
the  services  Keystone  is required to perform  under the  Advisory  Agreement.
Keystone  believes  that the cost,  value and specific  application  of research
services are indeterminable and cannot be practically allocated between the Fund
and its other  clients  who may  indirectly  benefit  from the  availability  of
research services.  Similarly,  the Fund may indirectly benefit from information
made  available  as a result  of  transactions  effected  for  Keystone's  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
follows such a practice,  it will do so on a basis that is fair and equitable to
the Fund.

         The Fund's Board of Trustees has determined  that the Fund may consider
sales of Fund  shares as a factor  when  selecting  brokers-dealers  to  execute
portfolio transactions,  subject to the requirements of best execution described
above.

Brokerage Commissions

The Fund  expects that  purchases  and sales of  municipal  bonds and  temporary
instruments  usually  will  be  principal  transactions.   Municipal  bonds  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.

General Brokerage Policies

         In order  to take  advantage  of the  availability  of  lower  purchase
prices, the Fund may participate,  if and when practicable, in group bidding for
the direct purchase from an issuer of certain securities.

         Keystone makes  investment  decisions for the Fund  independently  from
those of its other clients.  It may frequently develop,  however,  that Keystone
will make the same  investment  decision for more than one client.  Simultaneous
transactions  are  inevitable  when  the  same  security  is  suitable  for  the
investment  objective of more than one account.  When two or more of its clients
are engaged in the purchase or sale of the same security, Keystone will allocate
the  transactions  according  to a  formula  that  is  equitable  to each of its
clients. Although, in some cases, this system could have a detrimental effect on
the price or volume of the Fund's  securities,  the Fund  believes that in other
cases its ability to  participate  in volume  transactions  will produce  better
executions.

         The Fund does not purchase portfolio  securities from or sell portfolio
securities to Keystone,  EKD or any of their affiliated  persons,  as defined in
the 1940 Act.

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



                                  SALES CHARGES


         The Fund may charge a contingent  deferred sales charge (a "CDSC") when
you redeem  certain of its shares within four calendar  years after you purchase
the shares. The Fund charges a CDSC as reimbursement for certain expenses,  such
as commissions or shareholder servicing fees, that it has incurred in connection
with the sale of its shares (see  "Distribution  Plan").  If  imposed,  the Fund
deducts the CDSC from the redemption proceeds you would otherwise receive. CDSCs
attributable  to your  shares  are,  to the  extent  permitted  by the  National
Association  of  Securities  Dealers,   Inc.  ("NASD"),   paid  to  EKD  or  its
predecessor.

Calculating the CDSC

         The CDSC is a declining  percentage  of the lesser of (1) the net asset
value of the shares you redeemed, or (2) the total cost of such shares. The CDSC
is calculated according to the following schedule:

         Redemption Timing                                          CDSC

         During the calendar year of purchase......................4.00%
         During the calendar year after the
           year of purchase........................................3.00%
         During the second calendar
           year after the year of purchase.........................2.00%
         During the third calendar year
           after the year of purchase..............................1.00%
         Thereafter................................................0.00%

         In  determining  whether a CDSC is payable  and, if so, the  percentage
charge applicable, the Fund assumes that you have redeemed shares not subject to
a CDSC first and then it will redeem shares you have held the longest first.

         CDSC  Waivers.  The Fund does not impose a CDSC when the amount you are
redeeming represents:

         1.       an  increase  in the value of the  shares  redeemed  above the
                  total cost of such  shares due to  increases  in the net asset
                  value per share of the Fund;

         2.       certain  shares for which the Fund did not pay a commission on
                  issuance,  including shares acquired  through  reinvestment of
                  dividend income and capital gains distributions;

         3.       shares  you  have  held  for all or part  of  more  than  four
                  consecutive calendar years;

         4.       shares that are held in the accounts of a shareholder  who has
                  died or become disabled;

         5.       a lump-sum  distribution  from a 401(k) plan or other  benefit
                  plan qualified under the Employee  Retirement  Income Security
                  Act of 1974 ("ERISA");

         6.       automatic withdrawals from the ERISA plan of a shareholder who
                  is a least 59 1/2 years old;

         7.       shares in an  account  that the Fund has  closed  because  the
                  account has an aggregate net asset value of less than $1,000;

         8.       automatic withdrawals under a Systematic Withdrawal Plan of up
                  to 1.00% per month of your initial account balance;

         9.       withdrawals  consisting of loan proceeds to a retirement  plan
                  participant;

         10.      financial  hardship  withdrawals  made  by a  retirement  plan
                  participant;

         11.      withdrawals  consisting of returns of excess  contributions or
                  excess deferral amounts made to a retirement plan;

         12.      shares  purchased  by a bank  or  trust  company  in a  single
                  account  in the name of such bank or trust  company as trustee
                  if the  initial  investment  in shares of the Fund,  any other
                  Keystone Classic fund, and/or any Evergreen  Keystone fund, is
                  at least $500,000 and any commission paid by the Fund and such
                  other fund at the time of such purchase is not more than 1% of
                  the amount invested;

         13.      shares purchased by any Director,  Trustee, officer, full-time
                  employee or sales representative of the Fund, Keystone,  First
                  Union  Keystone,  EKD or their  affiliates,  who has held such
                  position for at least ninety days; or

         14.      shares   purchased   by  pension  and   profit-sharing   plans
                  established  by such companies and their  affiliates,  for the
                  benefit  of their  Directors,  Trustees,  officers,  full-time
                  employees and sales representatives.

         Exchanges.  The Fund  does not  charge a CDSC on  exchanges  of  shares
between Keystone Classic funds that have adopted  distribution plans pursuant to
Rule 12b-1 under the 1940 Act.  If you do  exchange  shares of one such fund for
shares  of  another  such  fund,  the Fund will  deem the  calendar  year of the
exchange,  for purposes of any future CDSC,  to be the year the shares  tendered
for exchange were originally purchased.

                                DISTRIBUTION PLAN

- --------------------------------------------------------------------------------


         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund to use their assets to bear the 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 bears some of
the costs of selling its shares  under a  Distribution  Plan  adopted on June 1,
1983 pursuant to Rule 12b-1 (the "Distribution Plan").


         The Fund's  Distribution  Plan  provides that the Fund may expend up to
0.3125%  quarterly  (1.25% annually) of the average daily net asset value of its
shares to pay distribution  costs for sales of its shares and to pay shareholder
service fees. The NASD currently  limits such annual  expenditures  to 1.00%, 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 Fund's  Distribution  Plan plus interest at the prime rate plus
1% on  unpaid  amounts  thereof  (less  any  CDSC  paid by  shareholders  to the
Principal Underwriter).

         Payments  under  the  Distribution  Plan  are  currently  made  to  the
Principal  Underwriter  (which  may  reallow  all or  part  to  others,  such as
broker-dealers)  (1) as  commissions  for Fund shares sold,  (2) as  shareholder
service fees in respect to shares maintained by the recipient and outstanding on
the Fund's  books for  specified  periods and (3) as  interest.  Amounts paid or
accrued to the Principal  Underwriter  and its  predecessor in the aggregate may
not exceed the annual limitations  referred to above. The Principal  Underwriter
generally  reallows to  broker-dealers  or others a commission equal to 4.00% of
the price paid for each Fund share sold as well as a shareholder  service fee at
a rate of 0.25% per annum of the net asset  value of shares  maintained  by such
recipient and outstanding on the books of the Fund for specified periods.

         If the Fund is unable to pay the Principal  Underwriter a commission on
a new sale because the annual  maximum  (0.75% of average  daily net assets) has
been reached,  the  Principal  Underwriter  intends,  but is not  obligated,  to
continue  to accept  new orders for the  purchase  of Fund  shares and to pay or
accrue commissions and service fees to broker-dealers in excess of the amount it
currently  receives  from  the  Fund  ("Advances").  While  the Fund is under no
contractual obligation to reimburse the Principal Underwriter or its predecessor
for Advances,  the Principal Underwriter and its predecessor intend to seek full
payment for such  Advances  from the Fund  (together  with interest at the prime
rate plus 1.00%) at such time in the future as, and to the extent that,  payment
thereof by the Fund would be within permitted limits.  EKIS currently intends to
seek  payment  of  interest  only  on such  Advances  paid  or  accrued  by EKIS
subsequent to July 7, 1992. If the Fund's  Independent  Trustees  authorize such
payments, the effect would be to extend the period of time during which the Fund
incurs the maximum amount of costs allowed by the Distribution Plan.

         The  Distribution  Plan  may be  terminated  at any  time  by vote of a
majority of the Independent Trustees or by vote of a majority of the outstanding
voting shares of the Fund. If the Distribution Plan is terminated,  EKD will ask
the Independent Trustees to take whatever action they deem appropriate under the
circumstances with respect to payment of such Advances.

         The total amounts paid by the Fund under the foregoing arrangements may
not exceed the maximum Distribution Plan limit specified above. In addition, the
amounts  and  purposes  of  expenditures  under  the  Distribution  Plan must be
reported to the Fund's Independent  Trustees  quarterly.  The Fund's Independent
Trustees may require or approve  changes in the  implementation  or operation of
the Distribution  Plan, and may also require that total expenditures by the Fund
under the Distribution  Plan be kept within limits lower than the maximum amount
permitted  by the  Distribution  Plan as  stated  above.  If such  costs are not
limited by the Independent Trustees,  such costs could, for some period of time,
be higher than such costs  permitted  by most other plans  presently  adopted by
other investment companies.

         The  Distribution  Plan  may be  terminated  at any time by vote of the
Independent  Trustees  or by  vote  of a  majority  of  the  outstanding  voting
securities  of  the  Fund.  Any  change  in the  Distribution  Plan  that  would
materially  increase the  distribution  expenses of the Fund provided for in the
Distribution Plan requires  shareholder  approval.  Otherwise,  the Distribution
Plan may be amended by the votes of the majority of both (1) the Fund's Board of
Trustees and (2) the  Independent  Trustees,  cast in person at a meeting called
for the purpose of voting on such amendment.

         While the 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.

         Whether any  expenditure  under the  Distribution  Plan is subject to a
state expense limit will depend upon the nature of the expenditure and the terms
of the state law,  regulation  or order  imposing  the  limit.  A portion of the
Fund's  Distribution  Plan  expenses  may  be  includable  in the  Fund's  total
operating  expenses for purposes of  determining  compliance  with state expense
limits.

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

* This Trustee may be considered an  "interested  person" of the Fund within the
meaning of the 1940 Act.

         For the fiscal year ended December 31, 1996,  none of the affiliated or
Independent  Trustees and officers of the Fund received any direct  remuneration
from the Fund. For the year ending  December 31, 1996,  fees paid to Independent
Trustees on a fund complex wide basis (which  included  approximately  60 mutual
funds) were approximately $846,350. On March 29, 1996, the Trustees and officers
of the Fund,  as a group,  beneficially  owned less than 1% of the  Fund's  then
outstanding shares.

         Except as set forth above,  the address of all the Fund's  Trustees and
officers is 200 Berkeley Street, Boston, Massachusetts 02116-5034.

         Set forth below for each of the Trustees receiving in excess of $60,000
for the fiscal  period of  January  1, 1996  through  December  31,  1996 is the

                                   INVESTMENT ADVISER


         Subject to the general  supervision  of the Fund's  Board of  Trustees,
Keystone provides investment advice,  management and administrative  services to
the Fund.

         On  December  11,  1996,  the  predecessor  corporation  to First Union
Keystone,  Keystone  Investments,  Inc. ("Keystone  Investments") and indirectly
each subsidiary of Keystone Investments,  including Keystone, were acquired (the
"Acquisition")  by First  Union  National  Bank of North  Carolina  ("FUNB"),  a
wholly-owned  subsidiary of First Union  Corporation  ("First Union").  Keystone
Investments  was acquired by FUNB by merger into a  wholly-owned  subsidiary  of
FUNB,  which  entity  then  assumed the name "First  Union  Keystone,  Inc." and
succeeded to the business of the predecessor corporation. Contemporaneously with
the Acquisition,  the Fund entered into a new investment advisory agreement with
Keystone and into a principal  underwriting  agreement  with EKD, a wholly-owned
subsidiary of The BISYS Group,  Inc. The new investment  management and advisory
agreement (the "Advisory  Agreement")  was approved by the  shareholders  of the
Fund on December 9, 1996, and became effective on December 11, 1996. As a result
of the above transactions,  Keystone Management,  Inc. ("Keystone  Management"),
which,  prior to the Acquisition,  acted as the Fund's  investment  manager,  no
longer acts as such to the Fund.  Keystone  currently provides the Fund with all
the services that may previously have been provided by Keystone Management.

         First Union Keystone and each of its subsidiaries,  including Keystone,
are now  indirectly  owned by First  Union.  First  Union  is  headquartered  in
Charlotte,  North Carolina,  and had $140 billion in  consolidated  assets as of
December 31,  1996.  First Union and its  subsidiaries  provide a broad range of
financial  services to individuals and businesses  throughout the United States.
The Capital  Management  Group of FUNB,  Keystone and Evergreen Asset Management
Corp.,  a  wholly-owned  subsidiary  of FUNB,  manage or  otherwise  oversee the
investment of over $60 billion in assets as of December 31, 1996, belonging to a
wide range of clients, including the Evergreen Keystone Family of Funds.

         Pursuant to the Advisory  Agreement and subject to the  supervision  of
the  Fund's  Board  of  Trustees,  Keystone  furnishes  to the  Fund  investment
advisory,   management  and  administrative  services,  office  facilities,  and
equipment in  connection  with its services  for  managing  the  investment  and
reinvestment  of the  Fund's  assets.  Keystone  pays  for  all of the  expenses
incurred in connection with the provision of its services.

         All charges and expenses,  other than those specifically referred to as
being borne by Keystone,  will be paid by the Fund,  including,  but not limited
to, (1) custodian  charges and expenses;  (2) bookkeeping and auditors'  charges
and expenses;  (3) transfer agent charges and expenses; (4) fees and expenses of
Independent Trustees; (5) brokerage commissions, brokers' fees and expenses; (6)
issue and transfer taxes;  (7) costs and expenses under the  Distribution  Plan;
(8) taxes and trust fees payable to governmental agencies; (9) the cost of share
certificates;  (10) fees and expenses of the registration  and  qualification of
the Fund and its  shares  with  the  Securities  and  Exchange  Commission  (the
"Commission")  or  under  state or  other  securities  laws;  (11)  expenses  of
preparing,   printing  and  mailing   prospectuses,   statements  of  additional
information,  notices,  reports and proxy materials to shareholders of the Fund;
(12) expenses of shareholders' and Trustees' meetings; (13) charges and expenses
of legal  counsel for the Fund and for the  Independent  Trustees of the Fund on
matters relating to the Fund; and (14) charges and expenses of filing annual and
other reports with the Commission and other  authorities,  and all extraordinary
charges and expenses of the Fund.

         The Fund pays  Keystone a fee at the end of each month for its services
consisting of (i) an amount calculated as set forth below:
                                                             Aggregate Net Asset

- --------------------------------------------------------------------------------


0.50% of the next            2.0% of Gross Dividend          $ 100,000,000, plus
0.45% of the next            and Interest Income Plus        $ 100,000,000, plus
0.40% of the next                                            $ 100,000,000, plus
0.35% of the next                                            $ 100,000,000, plus
0.30% of the next                                            $ 100,000,000, plus
0.25% of amounts over                                        $ 500,000.000;

and (ii) an amount equal to the amount of the reimbursable  expenses of Keystone
accrued during such calendar month.

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

         The  Advisory  Agreement  continues  in effect  for two years  from its
effective  date and,  thereafter,  from year to year only if  approved  at least
annually  by the Board of Trustees of the Fund or by a vote of a majority of the
Fund's  outstanding  shares (as defined in the 1940 Act).  In either  case,  the
terms of the Advisory Agreement and continuance  thereof must be approved 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.  The  Advisory
Agreement will terminate automatically upon its assignment.

                              PRINCIPAL UNDERWRITER

- --------------------------------------------------------------------------------


         The Fund has  entered  into a  Principal  Underwriting  Agreement  (the
"Underwriting  Agreement")  with EKD. EKD,  which is not  affiliated  with First
Union, replaces EKIS as the Fund's principal underwriter. EKIS may no longer act
as principal  underwriter of the Fund due to regulatory  restrictions imposed by
the  Glass-Steagall  Act upon national banks such as FUNB and their  affiliates,
that  prohibit  such  entities  from acting as the  underwriters  of mutual fund
shares.  While EKIS may no longer act as  principal  underwriter  of the Fund as
discussed above, EKIS may continue to receive  compensation from the Fund or EKD
in respect of  underwriting  and  distribution  services  performed prior to the
termination  of EKIS as principal  underwriter.  In  addition,  EKIS may also be
compensated by EKD for the provision of certain  marketing  support  services to
EKD at an annual  rate of up to 0.75% of the  average  daily  net  assets of the
Fund, subject to certain restrictions.

         EKD, as agent,  has agreed to use its best  efforts to find  purchasers
for  the  shares.   EKD  may  retain  and  employ   representatives  to  promote
distribution  of the shares  and may  obtain  orders  from  broker-dealers,  and
others,  acting as  principals,  for sales of shares to them.  The  Underwriting
Agreement  provides that EKD will bear the expense of preparing,  printing,  and
distributing  advertising and sales literature and  prospectuses  used by it. In
its capacity as principal underwriter, EKD or EKIS, its predecessor, may receive
payments from the Fund pursuant to the Fund's Distribution Plan.

         The  Underwriting  Agreement  provides that it will remain in effect as
long as its terms  and  continuance  are  approved  annually  (i) by a vote of a
majority  of the  Independent  Trustees,  and (ii) by vote of a majority  of the
Trustees, in each case, cast in person at a meeting called for that purpose.

         The Underwriting  Agreement may be terminated,  without penalty,  on 60
days'  written  notice by the Board of  Trustees  or by a vote of a majority  of
outstanding shares. The Underwriting Agreement will terminate automatically upon
its assignment.

         From time to time, if, in EKD's judgment, it could benefit the sales of
Fund shares, EKD may provide to selected  broker-dealers  promotional  materials
and selling aids,  including,  but not limited to, personal  computers,  related
software and Fund data files.

                                SUB-ADMINISTRATOR

- --------------------------------------------------------------------------------


         BISYS provides  personel to serve as officers of the Fund, and provides
certain  administrative  services to the Fund  pursuant  to a  sub-administrator
agreement. For its services under that agreement, BISYS receives from Keystone a
fee based on the aggregate  average daily net assets of the Fund at a rate based
on the total  assets of all mutual  funds  administered  by BISYS for which FUNB
affiliates  also  serve as  investment  adviser.  The  sub-administrator  fee is
calculated in accordance with the following schedule:

                              Aggregate Average Daily Net Assets Of Mutual Funds
Sub-Administrator               Administered By BISYS For Which Any Affiliate Of
Fee                                            FUNB Serves As Investment Adviser
- --------------------------------------------------------------------------------

0.0040%                                      on assets in excess of $25 billion



         The total  assets of the mutual  funds for which FUNB  affiliates  also
serve as investment advisers were approximately $29.2 billion as of February 28,
1997.

- --------------------------------------------------------------------------------


                              DECLARATION OF TRUST

- --------------------------------------------------------------------------------


         The Fund is a Massachusetts business trust originally established under
a Declaration of Trust dated April 12, 1977, as amended and restated on July 27,
1993 (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. 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 and the creation of  additional  series and/or
classes of series of Fund shares.  Each share represents an equal  proportionate
interest  in the Fund with each other  share of that  class.  Upon  liquidation,
shares are entitled to a pro rata share in the net assets of their class of Fund
shares.  Shareholders shall have no preemptive or conversion rights.  Shares are
transferable. The Fund currently intends to issue only one class of shares.

Shareholder Liability

         Pursuant to court decisions or other theories of law, shareholders of a
Massachusetts  business  trust  could  possibly  be held  personally  liable  as
partners for the obligations of the Fund. The  possibility of Fund  shareholders
incurring  financial loss for that reason appears remote,  however,  because the
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 Fund's Board of 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. There shall be no cumulative
voting in the election of Trustees.

         After the initial meeting as described  above,  no further  meetings of
shareholders for the purpose of electing  Trustees will be held, unless required
by law or 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 shareholder's meeting for the 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 cease to hold office or may be removed  from office (as
the case may be) (1) at any time by a 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 outstanding  shares.
Any  Trustee  may  voluntarily  resign  from  office.  Limitation  of  Trustees'
Liability

         The Declaration of Trust provides that a Trustee will not be liable for
errors of judgment or mistakes of fact or law, but nothing in the Declaration of
Trust  protects a Trustee  against any liability to which he would  otherwise be
subject by any reason of willful  misfeasance,  bad faith,  gross  negligence or
reckless disregard of his duties involved in the conduct of his office.

                 STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS

- --------------------------------------------------------------------------------


         Total  return  quotations  for the Fund as they may appear from time to
time in  advertisements  are calculated by finding the average annual compounded
rates of return  over the one-,  five- and  ten-year  periods on a  hypothetical
$1,000  investment  that would equate the initial amount  invested 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 one,
five or ten year periods.

         The  annual  total  return  of the Fund for the one year  period  ended
December 31, 1996,  including  applicable  sales charge,  was 0.21%. The average
annual  returns for the five- and ten-years  ended  December 31, 1996 were 5.91%
and 6.64%, respectively (including CDSCs).

         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  yield for the
30-day period ended December 31, 1996 was 5.09%.

         Tax  equivalent  yield is, in general,  the current  yield divided by a
factor  equal to one minus a stated  income  tax rate and  reflects  the yield a
taxable investment would have to achieve in order to equal on an after tax-basis
a tax exempt yield.  The tax equivalent yield for an investor in the 31% federal
tax bracket for the 30-day period ended December 31, 1996 was 7.38%.

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

                             CORPORATE BOND RATINGS

A.  S&P Corporate Bond Ratings

         A  S&P   corporate   bond  rating  is  a  current   assessment  of  the
creditworthiness  of an  obligor,  including  obligors  outside  the U.S.,  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:

         a.  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;

         b.       Nature of and provisions of the obligation; and

         c.  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 AA to BBB may be modified  by the  addition of a plus or
minus sign to show relative standing within the major rating categories.

         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.

         3. A - Debt rated A has a strong  capacity  to pay  interest  and repay
principal  although it is somewhat more  susceptible  to the adverse  effects of
changes in  circumstances  and  economic  conditions  than debt in higher  rated
categories.

         4. BBB - Debt rated BBB is regarded  as having an adequate  capacity to
pay  interest  and  repay  principal.  Whereas  it  normally  exhibits  adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened  capacity to pay interest and repay  principal
for debt in this category than in higher rated categories.

         5. BB, B, CCC, CC and C - Debt rated BB, B, CCC, CC and C is  regarded,
on  balance,  as  predominantly  speculative  with  respect to  capacity  to pay
interest and repay principal in accordance with the terms of the obligation.  BB
indicates  the  lowest  degree  of  speculation  and C  the  highest  degree  of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures to adverse conditions.

         6. CI - The rating CI is reserved for income bonds on which no interest
is being paid.

         7. D - Debt  rated D is in  default,  and  payment of  interest  and/or
repayment of principal is in arrears.

B.  Moody's Corporate Bond Ratings

         Moody's ratings 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 the 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.

         3. A -  Bonds  that  are  rated A  possess  many  favorable  investment
attributes and are to be considered as upper medium grade  obligations.  Factors
giving  security to principal and interest are considered  adequate but elements
may be present  that  suggest a  susceptibility  to  impairment  sometime in the
future.

         4. Baa - Bonds  that are  rated  Baa are  considered  as  medium  grade
obligations,  i.e.,  they are  neither  highly  protected  nor  poorly  secured.
Interest  payments and principal  security  appear  adequate for the present but
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

         5. Ba -  Bonds  that  are  rated  Ba are  judged  to  have  speculative
elements.  Their  future  cannot  be  considered  as  well  assured.  Often  the
protection of interest and  principal  payments may be very moderate and thereby
not well safeguarded during both good and bad times over the future.
Uncertainty of position characterizes bonds in this class.

         6. B - Bonds that are rated B  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

         7. Caa - Bonds that are rated Caa are of poor standing. Such issues may
be in  default  or there may be  present  elements  of danger  with  respect  to
principal or interest.

         8. Ca - Bonds  that  are  rated  Ca  represent  obligations  which  are
speculative  in a high  degree.  Such  issues are often in default or have other
market shortcomings.

         9. C - Bonds  that are rated as C are the lowest  rated  class of bonds
and issues so rated can be regarded as having  extremely  poor prospects of ever
attaining any real investment standing.

         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.


                          ZERO COUPON "STRIPPED" BONDS

         A zero coupon "stripped" bond represents ownership in serially maturing
interest payments or principal payments on specific  underlying notes and bonds,
including  coupons  relating to such notes and bonds. The interest and principal
payments are direct  obligations of the issuer.  Coupon zero coupon bonds of any
series  mature  periodically  from the date of issue of such series  through the
maturity date of the  securities  related to such series.  Principal zero coupon
bonds mature on the date specified therein,  which is the final maturity date of
the related  securities.  Each zero coupon bond entitles the holder to receive a
single payment at maturity.  There are no periodic  interest  payments on a zero
coupon bond.
Zero coupon bonds are offered at discounts from their face amounts.

         In general,  owners of zero  coupon  bonds have  substantially  all the
rights  and  privileges  of  owners  of the  underlying  coupon  obligations  or
principal  obligations.  Owners of zero coupon bonds have the right upon default
on the  underlying  coupon  obligations  or  principal  obligations  to  proceed
directly  and  individually  against  the issuer and are not  required to act in
concert with other holders of zero coupon bonds.

         For federal  income tax purposes,  a purchaser of principal zero coupon
bonds or coupon zero coupon bonds (either  initially or in the secondary market)
is treated as if the buyer had  purchased a corporate  obligation  issued on the
purchase date with an original  issue discount equal to the excess of the amount
payable at maturity over the purchase  price.  The purchaser is required to take
into income each year as ordinary income an allocable  portion of such discounts
determined on a "constant yield" method.  Any such income increases the holder's
tax basis for the zero coupon  bond,  and any gain or loss on a sale of the zero
coupon bonds relative to the holder's basis,  as so adjusted,  is a capital gain
or loss.  If the holder owns both  principal  zero coupon  bonds and coupon zero
coupon bonds representing interest in the same underlying issue of securities, a
special basis  allocation  rule  (requiring the aggregate  basis to be allocated
among the items sold and retained  based on their relative fair market values at
the time of sale) may apply to determine  the gain or loss on a sale of any such
zero coupon bonds items.


                           PAYMENT-IN-KIND SECURITIES

         Payment-in-kind  ("PIK")  securities  pay  interest  in either  cash or
additional  securities,  at the issuer's  option,  for a specified  period.  The
issuer's option to pay in additional securities typically ranges from one to six
years,  compared to an average  maturity for all PIK securities of eleven years.
Call  protection  and sinking fund  features are  comparable to those offered on
traditional debt issues.

         PIKs,  like  zero  coupon  bonds,  are  designated  to give  an  issuer
flexibility in managing cash flow. Several PIKs are senior debt. In other cases,
where  PIKs  are   subordinated,   most  senior  lenders  view  them  as  equity
equivalents.

         An advantage of PIKs for the issuer - as with zero coupon  securities -
is that  interest  payments are  automatically  compounded  (reinvested)  at the
stated coupon rate, which is not the case with cashpaying  securities.  However,
PIKs are gaining  popularity  over zeros since  interest  payments in additional
securities can be monetized and are more tangible than accretion of a discount.

         As a group,  PIK bonds trade flat  (i.e.,  without  accrued  interest).
Their  price is  expected to reflect an amount  representing  accreted  interest
since the last payment.  PIKs generally  trade at higher yields than  comparable
cash-paying  securities of the same issuer. Their premium yield is the result of
the lesser  desirability  of non-cash  interest,  the more limited  audience for
non-cash  paying  securities,  and the fact that  many PIKs have been  issued to
equity investors who do not normally own or hold such securities.

         Calculating the true yield on a PIK security requires a discounted cash
flow  analysis  if the  security  (ex  interest)  is  trading  at a premium or a
discount,  because the realizable  value of additional  payments is equal to the
current market value of the underlying security, not par.

         Regardless of whether PIK securities are senior or deeply subordinated,
issuers are highly  motivated to retire them because they are usually their most
costly form of capital.  Sixty-eight  percent of the PIK debentures issued prior
to 1987  have  already  been  redeemed,  and  approximately  35% of the over $10
billion PIK debentures issued through year-end 1988 have been retired.


                          EQUIPMENT TRUST CERTIFICATES

         Equipment Trust Certificates are a mechanism for financing the purchase
of  transportation  equipment,  such as railroad cars and  locomotives,  trucks,
airplanes and oil tankers.

         Under an  equipment  trust  certificate,  the  equipment is used as the
security  for the debt and title to the  equipment  is vested in a trustee.  The
trustee leases the equipment to the user, i.e., the railroad,  airline, trucking
or oil company.  At the same time equipment  trust  certificates in an aggregate
amount equal to a certain percentage of the equipment's  purchase price are sold
to lenders.  The trustee pays the proceeds from the sale of  certificates to the
manufacturer.  In addition,  the company  using the  equipment  makes an initial
payment of rent equal to their  balance of the  purchase  price to the  trustee,
which the trustee  then pays to the  manufacturer.  The trustee  collects  lease
payments from the company and uses the payments to pay interest and principal on
the  certificates.  At maturity,  the  certificates  are redeemed and paid,  the
equipment is sold to the company and the lease is terminated.

         Generally,  these  certificates  are  regarded  as  obligations  of the
company  that is  leasing  the  equipment  and are shown as  liabilities  on its
balance  sheet.  However,  the company does not own the equipment  until all the
certificates  are redeemed and paid. In the event the company defaults under its
lease,  the trustee  terminates the lease.  If another lessee is available,  the
trustee  leases  the  equipment  to  another  user  and  makes  payments  on the
certificates from new lease rentals.


                              LIMITED PARTNERSHIPS

         The Fund may  invest in  limited  and master  limited  partnerships.  A
limited partnership is a partnership consisting of one or more general partners,
jointly and severally responsible as ordinary partners, and by whom the business
is conducted, and one or more limited partners who contribute cash as capital to
the  partnership  and  who  generally  are  not  liable  for  the  debts  of the
partnership beyond the amounts contributed. Limited partners are not involved in
the day-to-day management of the partnership. They receive income, capital gains
and other tax benefits  associated  with the  partnership  project in accordance
with  terms   established  in  the   partnership   agreement.   Typical  limited
partnerships  are in real estate,  oil and gas and equipment  leasing,  but they
also finance movies, research and development and other projects.

         For an  organization  classified  as a  partnership  under the Internal
Revenue Code, each item of income, gain, loss, deduction and credit is not taxed
at the  partnership  level but flows  through to the  holder of the  partnership
unit.  This allows the  partnership to avoid taxation and to pass through income
to the holder of the partnership unit at lower individual rates.

         A master limited partnership is a publicly traded limited  partnership.
The partnership units are registered with the Securities and Exchange Commission
and are freely  exchanged  on a securities  exchange or in the  over-the-counter
market.


                         MOODY'S PREFERRED STOCK RATINGS

         Preferred stock ratings and their definitions are as follows:

         1. aaa: An issue that is rated aaa is  considered  to be a  top-quality
preferred stock.  This rating indicates good asset protection and the least risk
of dividend impairment within the universe of preferred stocks.

         2. aa: An issue that is rated aa is  considered a high-grade  preferred
stock. This rating indicates that there is a reasonable  assurance that earnings
and asset  protection will remain  relatively well maintained in the foreseeable
future.

         3. a: An issue  that is  rated a is  considered  to be an  upper-medium
grade preferred stock. While risks are judged to be somewhat greater then in the
aaa and aa  classification,  earnings and asset  protection  are,  nevertheless,
expected to be maintained at adequate levels.

         4. baa: An issue that is rated baa is considered  to be a  medium-grade
preferred stock, neither highly protected nor poorly secured. Earnings and asset
protection  appear  adequate at present but may be  questionable  over any great
length of time.

         5. ba:  An issue  that is rated ba is  considered  to have  speculative
elements and its future  cannot be considered  well assured.  Earnings and asset
protection may be very moderate and not well safeguarded during adverse periods.
Uncertainty of position characterizes preferred stocks in this class.

         Moody's  applies  numerical  modifiers  1,  2  and  3  in  each  rating
classification.  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.


                            MONEY MARKET INSTRUMENTS

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

Commercial Paper Ratings

         Commercial  paper  rated A-1 by  Standard  & Poor's  has the  following
characteristics:  Liquidity ratios are adequate to meet cash  requirements.  The
issuer's long-term senior debt is rated A or better,  although in some cases BBB
credits  may be  allowed.  The  issuer  has  access to at least  two  additional
channels of  borrowing.  Basic  earnings and cash flow have an upward trend with
allowance made for unusual  circumstances.  Typically,  the issuer's industry is
well established and the issuer has a strong position within the industry.

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

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

United States Government Securities

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

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

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

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 which are members of the Federal  Reserve System
or the Federal  Deposit  Insurance  Corporation  and have at least $1 billion in
deposits as of the date of their most recently published financial statements.

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

Bankers' Acceptances

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


                              OPTIONS TRANSACTIONS

Writing Covered Options

         The Fund writes only covered options.  Options written by the Fund will
normally  have  expiration  dates of not more  than  nine  months  from the date
written.  The exercise price of the options may be below, equal to, or above the
current market values of the underlying  securities at the times the options are
written.

         Unless the option has been exercised,  the Fund may close out an option
it has written by effecting a closing purchase transaction, whereby it purchases
an option  covering the same  underlying  security and having the same  exercise
price and expiration  date ("of the same series") as the one it has written.  If
the Fund  desires to sell a  particular  security on which it has written a call
option,  it will effect a closing purchase  transaction prior to or concurrently
with the sale of the  security.  If the  Fund is able to  enter  into a  closing
purchase transaction, the Fund will realize a profit (or loss) from such
transaction  if the cost of such  transaction is less (or more) than the premium
received from the writing of the option.

         An option position may be closed out only in a secondary  market for an
option of the same  series.  Although the Fund will  generally  write only those
options for which there appears to be an active  secondary  market,  there is no
assurance that a liquid secondary market will exist for any particular option at
any particular time, and for some options no secondary market may exist. In such
event it might not be possible to effect a closing  transaction  in a particular
option.  If the Fund as a  covered  call  option  writer  is  unable to effect a
closing  purchase  transaction,  it will  not be able  to  sell  the  underlying
securities  until the option  expires or it delivers the  underlying  securities
upon exercise.

         Because the Fund intends to qualify as a regulated  investment  company
under the Internal  Revenue Code, the extent to which the Fund may write covered
call options and enter into so-called "straddle"  transactions involving put and
call options may be limited.

         Many options are traded on  registered  securities  exchanges.  Options
traded on such exchanges are issued by the Options Clearing Corporation (OCC), a
clearing corporation which assumes  responsibility for the completion of options
transactions.

Purchasing Put and Call Options

         The Fund can close out a put or call option it has written by effecting
a closing  purchase  transaction;  for example,  the Fund may close out a put or
call  option it has  written  by buying  an option  identical  to the one it has
written.  If,  however,  a  secondary  market  does not exist at a time the Fund
wishes to effect a closing sale transaction,  the Fund will have to exercise the
option to realize any profit.  If a covered call option  writer  cannot effect a
closing transaction,  it cannot sell the underlying  securities until the option
expires or is exercised.  In addition,  in a transaction  in which the Fund does
not own the security underlying a put option it has purchased, the Fund would be
required,  in the absence of a secondary  market,  to  purchase  the  underlying
security  before it could  exercise  the option,  thereby  incurring  additional
transaction costs.

         The  Fund  will not  purchase  a put  option  if,  as a result  of such
purchase,  more than 10% of its total  assets  would be invested in premiums for
such options. The Fund's ability to purchase put and call options may be limited
by the Internal  Revenue Code's  requirements  for  qualification as a regulated
investment company.

Option Writing and Related Risks

         The Fund may write  covered call and put  options.  A call option gives
the  purchaser of the option the right to buy, and the writer the  obligation to
sell,  the  underlying  security at the exercise price during the option period.
Conversely,  a put option gives the purchaser the right to sell,  and the writer
the obligation to buy, the underlying  security at the exercise price during the
option period.

         So long as the  obligation of the writer  continues,  the writer may be
assigned an exercise  notice by the  broker-dealer  through  whom the option was
sold. The exercise notice would require the writer to deliver,  in the case of a
call, or take delivery of, in the case of a put, the underlying security against
payment of the exercise price. This obligation terminates upon expiration of the
option,  or at such  earlier  time as the  writer  effects  a  closing  purchase
transaction  by  purchasing  an option of the same series as the one  previously
sold.  Once an option has been  exercised,  the writer may not execute a closing
purchase  transaction.  For  options  traded on  national  securities  exchanges
(Exchanges),  to secure the obligation to deliver the underlying security in the
case of a call option, the writer of the option is required to deposit in escrow
the underlying security or other assets in accordance with the rules of the OCC,
an  institution  created to  interpose  itself  between  buyers  and  sellers of
options.  Technically, the OCC assumes the order side of every purchase and sale
transaction  on an  Exchange  and  by  doing  so,  gives  its  guarantee  to the
transaction.

         The principal  reason for writing options on a securities  portfolio is
to attempt to realize,  through the receipt of premiums,  a greater  return than
would be realized on the underlying securities alone. In return for the premium,
the covered call option  writer has given up the  opportunity  for profit from a
price  increase in the  underlying  security above the exercise price so long as
the option  remains  open,  but retains the risk of loss should the price of the
security decline.  Conversely, the put option writer gains a profit, in the form
of a premium,  so long as the price of the underlying security remains above the
exercise  price,  but assumes an obligation to purchase the underlying  security
from the buyer of the put option at the exercise price, even though the price of
the security may fall below the  exercise  price,  at any time during the option
period.  If an option  expires,  the writer realizes a gain in the amount of the
premium.  Such a gain may, in the case of a covered call option,  be offset by a
decline in the market value of the underlying security during the option period.
If a call option is exercised,  the writer realizes a gain or loss from the sale
of the  underlying  security.  If a put option is  exercised,  the  writer  must
fulfill his  obligation  to purchase  the  underlying  security at the  exercise
price,  which  will  usually  exceed  the then  market  value of the  underlying
security.  In addition,  the premium paid for the put effectively  increases the
cost of the underlying  security,  thus reducing the yield  otherwise  available
from such securities.

         Because  the Fund can write only  covered  options,  it may at times be
unable to write  additional  options  unless it sells a portion of its portfolio
holdings to obtain new debt securities against which it can write options.  This
may result in higher portfolio  turnover and  correspondingly  greater brokerage
commissions and other transaction costs.

         To the extent that a secondary  market is available the covered  option
writer  may close out  options  it has  written  prior to the  assignment  of an
exercise notice by purchasing,  in a closing purchase transaction,  an option of
the same series as the option previously  written. If the cost of such a closing
purchase,  plus  transaction  costs,  is greater than the premium  received upon
writing the original option, the writer will incur a loss on the transaction.

Options Trading Markets

         Options  which the Fund will trade are  generally  listed on Exchanges.
Exchanges  on which such  options  currently  are traded are the  Chicago  Board
Options Exchange and the American,  New York,  Pacific,  and Philadelphia  Stock
Exchanges.  Options on some  securities  may not be listed on any  Exchange  but
traded in the  over-the-counter  market.  Options traded in the over-the-counter
market involve the additional risk that securities dealers participating in such
transactions  would  fail to meet  their  obligations  to the  Fund.  The use of
options  traded in the  over-the-counter  market may be  subject to  limitations
imposed by certain state  securities  authorities.  In addition to the limits on
its use of options  discussed  herein,  the Fund is  subject  to the  investment
restrictions  described  in the  prospectus  and  the  statement  of  additional
information.

         The staff of the  Commission is of the view that the premiums which the
Fund pays for the purchase of unlisted options, and the value of securities used
to cover unlisted  options  written by the Fund are considered to be invested in
illiquid securities or assets for the purpose of calculating whether the Fund is
in compliance with its fundamental  investment  restriction  prohibiting it from
investing  more than 10% of its total  assets  (taken at  current  value) in any
combination of illiquid assets and securities.  The Fund intends to request that
the  Commission  staff  reconsider  its view. It is the intention of the Fund to
comply   with  the   staff's   current   position   and  the   outcome  of  such
reconsideration.

Special Considerations Applicable to Options

         On Treasury Bonds and Notes.  Because trading interest in U.S. Treasury
bonds and  notes  tends to center on the most  recently  auctioned  issues,  new
series of options with  expirations  to replace  expiring  options on particular
issues will not be introduced indefinitely.  Instead, the expirations introduced
at the  commencement of options trading on a particular issue will be allowed to
run  their  course,  with the  possible  addition  of a  limited  number  of new
expirations as the original ones expire. Options trading on each series of bonds
or notes will thus be phased out as new  options  are listed on the more  recent
issues,  and a full range of expiration  dates will not  ordinarily be available
for every series on which options are traded.

         On Treasury Bills.  Because the deliverable U.S.  Treasury bill changes
from week to week,  writers of U.S. Treasury bill call options cannot provide in
advance for their  potential  exercise  settlement  obligations by acquiring and
holding the underlying  security.  However, if the Fund holds a long position in
U.S. Treasury bills with a principal amount corresponding to the option contract
size, the Fund may be hedged from a risk standpoint.  In addition, the Fund will
maintain in a segregated  account with its Custodian  liquid assets  maturing no
later than those which would be  deliverable in the event of an assignment of an
exercise notice to ensure that it can meet its open option obligations.

          On GNMA  Certificates.  Options on GNMA certificates are not currently
traded on any Exchange. However, the Fund may purchase and write such options in
the over-the-counter market or, should they commence trading, on any Exchange.

         Since the remaining  principal  balance of GNMA  certificates  declines
each month as a result of mortgage payments,  the Fund, as a writer of a covered
GNMA  call  holding  GNMA  certificates  as  "cover"  to  satisfy  its  delivery
obligation in the event of assignment of an exercise  notice,  may find that its
GNMA  certificates no longer have a sufficient  remaining  principal balance for
this  purpose.  Should this occur,  the Fund will enter into a closing  purchase
transaction or will purchase additional GNMA certificates from the same pool (if
obtainable)  or  replacement  GNMA  certificates  in the cash market in order to
remain covered.

         A GNMA  certificate held by the Fund to cover an option position in any
but the nearest  expiration  month may cease to present  cover for the option in
the event of a decline in the GNMA coupon rate at which new pools are originated
under the FHA/VA loan  ceiling in effect at any given  time.  Should this occur,
the Fund will no longer  be  covered,  and the Fund  will  either  enter  into a
closing purchase  transaction or replace the GNMA certificate with a certificate
which represents  cover.  When the Fund closes its position or replaces the GNMA
certificate, it may realize an unanticipated loss and incur transaction costs.

         Risks  Pertaining to the Secondary  Market.  An option  position may be
closed out only in a secondary market for an option of the same series. Although
the Fund will  generally  purchase  or write only those  options for which there
appears to be an active  secondary  market,  there is no assurance that a liquid
secondary  market will exist for any particular  option at any particular  time,
and for some options no secondary  market may exist. In such event, it might not
be possible to effect  closing  transactions  in  particular  options,  with the
result that the Fund would have to exercise  its options in order to realize any
profit and might incur transaction costs in connection therewith. If the Fund as
a covered call option writer is unable to effect a closing purchase  transaction
in a secondary market, it will not be able to sell the underlying security until
the option expires or it delivers the underlying security upon exercise.

         Reasons  for the  absence  of a liquid  secondary  market  include  the
following:   (i)  insufficient   trading  interest  in  certain  options;   (ii)
restrictions imposed on transactions;  (iii) trading halts, suspensions or other
restrictions  imposed with respect to particular classes or series of options or
underlying securities; (iv) interruption of the normal operations on an Exchange
or by a broker;  (v) inadequacy of the  facilities of an Exchange,  the OCC or a
broker  handle  current  trading  volume;  or  (vi) a  decision  by one or  more
Exchanges  or a broker to  discontinue  the trading of options (or a  particular
class or series of options),  in which event the secondary  market in that class
or series of options would cease to exist, although outstanding options that had
been issued as a result of trades would generally  continue to be exercisable in
accordance with their terms.

         The hours of trading for options on U.S. government  securities may not
conform to the hours during which the underlying  securities are traded.  To the
extent that the option  markets  close  before the  markets  for the  underlying
securities,  significant  price  and  rate  movements  can  take  place  in  the
underlying markets that cannot be reflected in the option markets.


               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

         The Fund  intends to enter into  currency and other  financial  futures
contracts  as a hedge  against  changes  in  prevailing  levels of  interest  or
currency exchange rates to seek relative stability of principal and to establish
more  definitely  the  effective  return on  securities  held or  intended to be
acquired by the Fund or as a hedge  against  changes in the prices of securities
or currencies held by the Fund or to be acquired by the Fund. The Fund's hedging
may  include  sales of  futures  as an offset  against  the  effect of  expected
increases  in interest  or  currency  exchange  rates or  securities  prices and
purchases  of futures as an offset  against the effect of  expected  declines in
interest or currency exchange rates.

         For example,  when the Fund anticipates a significant  market or market
sector  advance,  it will  purchase a stock  index  futures  contract as a hedge
against not  participating  in such advance at a time when the Fund is not fully
invested.  The purchase of a futures  contract serves as a temporary  substitute
for the  purchase of  individual  securities  which may then be  purchased in an
orderly fashion. As such purchases are made, an equivalent amount of index based
futures contracts would be terminated by offsetting sales. In contrast, the Fund
would sell stock index  futures  contracts  in  anticipation  of or in a general
market or market sector  decline that may  adversely  affect the market value of
the Fund's  portfolio.  To the extent that the Fund's portfolio changes in value
in correlation with a given index,  the sale of futures  contracts on that index
would  substantially  reduce the risk to the  portfolio  of a market  decline or
change in  interest  rates,  and,  by so doing,  provide an  alternative  to the
liquidation  of the Fund's  securities  positions and the resulting  transaction
costs.

         The Fund intends to engage in options transactions which are related to
commodity  futures  contracts for hedging  purposes and in  connection  with the
hedging strategies described above.

         Although techniques other than sales and purchases of futures contracts
and related options  transactions could be used to reduce the Fund's exposure to
interest  rate  and/or  market  fluctuations,  the Fund may be able to hedge its
exposure  more  effectively  and perhaps at a lower cost through  using  futures
contracts and related  options  transactions.  While the Fund does not intend to
take delivery of the instruments underlying futures contracts it holds, the Fund
does not intend to engage in such futures contracts for speculation.

Futures Contracts

         Futures  contracts are  transactions in the commodities  markets rather
than in the securities  markets. A futures contract creates an obligation by the
seller to deliver to the buyer the  commodity  specified  in the  contract  at a
specified  future time for a specified  price.  The futures  contract creates an
obligation  by the buyer to accept  delivery  from the  seller of the  commodity
specified at the specified future time for the specified  price. In contrast,  a
spot transaction  creates an immediate  obligation for the seller to deliver and
the buyer to accept delivery of and pay for an identified commodity. In general,
futures contracts involve  transactions in fungible goods such as wheat,  coffee
and  soybeans.  However,  in the last  decade an  increasing  number of  futures
contracts have been developed which specify currencies, financial instruments or
financially based indices as the underlying commodity.

         U.S. futures  contracts are traded only on national  futures  exchanges
and are  standardized as to maturity date and underlying  financial  instrument.
The principal  financial futures exchanges in the United States are The Board of
Trade of the City of Chicago, the Chicago Mercantile Exchange, the International
Monetary Market (a division of the Chicago  Mercantile  Exchange),  the New York
Futures  Exchange and the Kansas City Board of Trade.  Each exchange  guarantees
performance  under  contract  provisions  through  a  clearing  corporation,   a
nonprofit  organization  managed  by the  exchange  membership,  which  is  also
responsible for handling daily  accounting of deposits or withdrawals of margin.
A futures commission  merchant ("Broker") effects each transaction in connection
with futures  contracts  for a  commission.  Futures  exchanges  and trading are
regulated  under the  Commodity  Exchange Act by the Commodity  Futures  Trading
Commission ("CFTC") and National Futures Association ("NFA").

Interest Rate Futures Contracts

         The sale of an interest rate futures  contract creates an obligation by
the Fund, as seller,  to deliver the type of financial  instrument  specified in
the contract at a specified  future time for a specified  price. The purchase of
an  interest  rate  futures  contract  creates  an  obligation  by the Fund,  as
purchaser, to accept delivery of the type of financial instrument specified at a
specified future time for a specified price. The specific  securities  delivered
or accepted,  respectively,  at settlement  date, are not determined until at or
near  that  date.  The  determination  is in  accordance  with the  rules of the
exchange on which the futures contract sale or purchase was made.

         Currently  interest rate futures  contracts can be purchased or sold on
90-day U.S.  Treasury  bills,  U.S.  Treasury  bonds,  U.S.  Treasury notes with
maturities between 6 1/2 and 10 years,  Government National Mortgage Association
("GNMA")  certificates,  90-day domestic bank  certificates of deposit,  90- day
commercial paper, and 90-day Eurodollar  certificates of deposit. It is expected
that futures  contracts  trading in  additional  financial  instruments  will be
authorized. The standard contract size is $100,000 for futures contracts in U.S.
Treasury bonds,  U.S. Treasury notes and GNMA  certificates,  and $1,000,000 for
the other designated  contracts.  While U.S. Treasury bonds, U.S. Treasury bills
and U.S.  Treasury  notes are  backed by the full  faith and  credit of the U.S.
government and GNMA certificates are guaranteed by a U.S. government agency, the
futures contracts in U.S. government  securities are not obligations of the U.S.
Treasury.

Index Based Futures Contracts

Stock Index Futures Contracts

         A stock index assigns  relative values to the common stocks included in
the index.  The index fluctuates with changes in the market values of the common
stocks so included.  A stock index futures contract is a bilateral  agreement by
which two parties agree to take or make delivery of an amount of cash equal to a
specified  dollar amount times the  difference  between the closing value of the
stock index on the  expiration  date of the  contract and the price at which the
futures  contract is  originally  made. No physical  delivery of the  underlying
stocks in the index is made.

         Currently,  stock index  futures  contracts can be purchased or sold on
the Standard and Poor's  Corporation  ("S&P") Index of 500 Stocks, the S&P Index
of 100 Stocks, the New York Stock Exchange Composite Index, the Value Line Index
and the Major Market  Index.  It is expected that futures  contracts  trading in
additional stock indices will be authorized.  The standard contract size is $500
times the value of the index.

         The Fund does not  believe  that  differences  between  existing  stock
indices will create any  differences  in the price  movements of the stock index
futures  contracts in relation to the movements in such indices.  However,  such
differences  in the  indices may result in  differences  in  correlation  of the
futures with movements in the value of the securities being hedged.

Other Index Based Futures Contracts

         It is  expected  that  bond  index and other  financially  based  index
futures  contracts will be developed in the future.  It is anticipated that such
index based futures  contracts will be structured in the same way as stock index
futures  contracts  but will be measured by changes in interest  rates,  related
indices or other  measures,  such as the consumer price index. In the event that
such futures  contracts are developed the Fund will sell interest rate index and
other index based futures  contracts to hedge against changes which are expected
to affect the Fund's portfolio.

         The purchase or sale of a futures contract differs from the purchase or
sale of a security, in that no price or premium is paid or received. Instead, to
initiate trading an amount of cash, cash equivalents,  money market instruments,
or U.S.  Treasury bills equal to approximately 1 1/2% (up to 5%) of the contract
amount must be  deposited  by the Fund with the Broker.  This amount is known as
initial  margin.  The  nature of  initial  margin  in  futures  transactions  is
different from that of margin in security transactions.  Futures contract margin
does not  involve  the  borrowing  of  funds  by the  customer  to  finance  the
transactions.

         Rather,  the initial  margin is in the nature of a performance  bond or
good  faith  deposit  on  the  contract  which  is  returned  to the  Fund  upon
termination of the futures  contract  assuming all contractual  obligations have
been satisfied.  The margin required for a particular futures contract is set by
the exchange on which the contract is traded, and may be significantly  modified
from time to time by the exchange during the term of the contract.

         Subsequent  payments,  called variation  margin, to the Broker and from
the Broker, are made on a daily basis as the value of the underlying  instrument
or index fluctuates  making the long and short positions in the futures contract
more or less valuable, a process known as mark-to-market.  For example, when the
Fund has purchased a futures contract and the price of the underlying  financial
instrument or index has risen,  that  position will have  increased in value and
the Fund will receive from the Broker a variation  margin  payment equal to that
increase in value.  Conversely,  where the Fund has purchased a futures contract
and the price of the underlying financial instrument or index has declined,  the
position  would be less  valuable  and the  Fund  would  be  required  to make a
variation  margin payment to the Broker.  At any time prior to expiration of the
futures  contract,   the  Fund  may  elect  to  close  the  position.   A  final
determination of variation  margin is then made,  additional cash is required to
be paid to or released by the Broker, and the Fund realizes a loss or gain.

         The Fund intends to enter into arrangements with its custodian and with
Brokers to enable its initial  margin and any  variation  margin to be held in a
segregated account by its custodian on behalf of the Broker.

         Although interest rate futures contracts by their terms call for actual
delivery  or  acceptance  of  financial  instruments,  and index  based  futures
contracts call for the delivery of cash equal to a specified dollar amount times
the difference  between the closing value of the index on the expiration date of
the contract and the price at which the futures  contract is originally made, in
most cases such  futures  contracts  are closed out before the  settlement  date
without the making or taking of delivery. Closing out a futures contract sale is
effected by an  offsetting  transaction  in which the Fund enters into a futures
contract  purchase  for  the  same  aggregate  amount  of the  specific  type of
financial  instrument or index and same delivery  date. If the price in the sale
exceeds the price in the  offsetting  purchase,  the Fund is paid the difference
and thus  realizes a gain.  If the  offsetting  purchase  price exceeds the sale
price, the Fund pays the difference and realizes a loss. Similarly,  the closing
out of a futures contract  purchase is effected by an offsetting  transaction in
which the Fund enters into a futures contract sale. If the offsetting sale price
exceeds the purchase  price,  the Fund  realizes a gain.  If the purchase  price
exceeds the  offsetting  sale price the Fund realizes a loss.  The amount of the
Fund's gain or loss on any transaction is reduced or increased, respectively, by
the amount of any transaction costs incurred by the Fund.

         As an example of an offsetting transaction, the contractual obligations
arising  from the sale of one contract of September  U.S.  Treasury  bills on an
exchange  may be  fulfilled  at any time  before  delivery  of the  contract  is
required (i.e., on a specified date in September,  the "delivery  month") by the
purchase of one contract of September U.S.  Treasury bills on the same exchange.
In such instance the difference  between the price at which the futures contract
was sold and the price paid for the  offsetting  purchase  after  allowance  for
transaction costs represents the profit or loss to the Fund.

         There can be no assurance, however, that the Fund will be able to enter
into an  offsetting  transaction  with  respect to a  particular  contract  at a
particular  time.  If  the  Fund  is  not  able  to  enter  into  an  offsetting
transaction,  the Fund will  continue  to be  required  to  maintain  the margin
deposits on the contract and to complete the contract according to its terms.

Options on Currency and Other Financial Futures

         The Fund intends to purchase call and put options on currency and other
financial  futures  contracts  and sell such  options to  terminate  an existing
position.  Options on currency and other financial futures contracts are similar
to options on stocks  except  that an option on a  currency  or other  financial
futures  contract gives the purchaser the right, in return for the premium paid,
to assume a position in a futures  contract (a long  position if the option is a
call and a short  position  if the option is a put)  rather  than to purchase or
sell stock,  currency or other  financial  instruments  at a specified  exercise
price at any time during the period of the option.  Upon exercise of the option,
the  delivery of the futures  position by the writer of the option to the holder
of the option will be accompanied by delivery of the accumulated  balance in the
writer's futures margin account.  This amount represents the amount by which the
market price of the futures contract at exercise exceeds, in the case of a call,
or is less than,  in the case of a put, the exercise  price of the option on the
futures  contract.  If an option is exercised  the last trading day prior to the
expiration  date of the option,  the  settlement  will be made  entirely in cash
equal to the  difference  between the exercise  price of the option and value of
the futures contract.

         The Fund intends to use options on currency and other financial futures
contracts in connection with hedging strategies.  In the future the Fund may use
such options for other purposes.

Purchase of Put Options on Futures Contracts

         The purchase of protective put options on commodity futures
contracts is analogous to the purchase of protective puts on individual  stocks,
where an  absolute  level of  protection  is sought  below  which no  additional
economic  loss would be incurred by the Fund.  Put options may be  purchased  to
hedge a  portfolio  of stocks or debt  instruments  or a position in the futures
contract upon which the put option is based.

Purchase of Call Options on Futures Contracts

         The purchase of a call option on a currency or other financial  futures
contract   represents  a  means  of  obtaining   temporary  exposure  to  market
appreciation  at limited  risk. It is analogous to the purchase of a call option
on an individual  stock which can be used as a substitute  for a position in the
stock  itself.  Depending  on the  pricing of the option  compared to either the
futures  contract  upon which it is based,  or upon the price of the  underlying
financial  instrument or index itself, the purchase of a call option may be less
risky than the ownership of the interest rate or index based futures contract or
the underlying  securities.  Call options on currency or other financial futures
contracts  may be  purchased  to hedge  against an interest  rate  increase or a
market advance when the Fund is not fully invested.

Use of New Investment Techniques Involving Currency and Other Financial Futures
Contracts or Related Options

         The Fund may employ new investment  techniques  involving  currency and
other financial futures contracts and related options.  The Fund intends to take
advantage of new  techniques in these areas which may be developed  from time to
time and which are consistent  with the Fund's  investment  objective.  The Fund
believes that no additional  techniques  have been  identified for employment by
the Fund in the foreseeable future other than those described above.

Limitations on Purchase and Sale of Futures Contracts and Related Options on
Such Futures Contracts

         The  Fund  will not  enter  into a  futures  contract  if,  as a result
thereof,  more than 5% of the Fund's total assets  (taken at market value at the
time of entering  into the  contract)  would be committed to margin  deposits on
such futures contracts.

         The Fund  intends  that  its  futures  contracts  and  related  options
transactions  will be entered into for traditional  hedging  purposes.  That is,
futures  contracts  will be sold to  protect  against a decline  in the price of
securities that the Fund owns or futures  contracts will be purchased to protect
the Fund against an increase in the price of  securities it intends to purchase.
The Fund does not intend to enter into futures contracts for speculation.

         In instances  involving the purchase of futures  contracts by the Fund,
an amount of cash and cash equivalents, equal to the market value of the futures
contracts  will be deposited in a segregated  account with the Fund's  Custodian
and/or in a margin  account  with a Broker to  collateralize  the  position  and
thereby insure that the use of such futures is unleveraged.

Federal Income Tax Treatment

         For federal  income tax purposes,  the Fund is required to recognize as
income  for each  taxable  year its net  unrealized  gains and losses on futures
contracts as of the end of the year as well as those  actually  realized  during
the year.  Any gain or loss  recognized  with  respect to a futures  contract is
considered to be 60% long term and 40% short term, without regard to the holding
period of the  contract.  In the case of a futures  transaction  classified as a
"mixed  straddle," the  recognition of losses may be deferred to a later taxable
year. The federal income tax treatment of gains or losses from  transactions  in
options on futures is unclear.

         In order for the Fund to continue  to qualify  for  federal  income tax
treatment as a regulated  investment  company,  at least 90% of its gross income
for a taxable year must be derived from qualifying income. Any net gain realized
from the closing out of futures contracts,  for purposes of the 90% requirement,
will be  qualifying  income.  In addition,  gains  realized on the sale or other
disposition  of  securities  held for less than three  months must be limited to
less  than 30% of the  Fund's  annual  gross  income.  The 1986 Tax Act  added a
provision   which   effectively   treats  both  positions  in  certain   hedging
transactions as a single transaction for the purpose of the 30% requirement. The
provision  provides that, in the case of any "designated  hedge,"  increases and
decreases  in the value of  positions  of the  hedge  are to be  netted  for the
purposes of the 30% requirement.  However,  in certain  situations,  in order to
avoid realizing a gain within a three month period,  the Fund may be required to
defer the closing out of a contract  beyond the time when it would  otherwise be
advantageous to do so.

Risks of Futures Contracts

         Currency and other financial  futures contracts prices are volatile and
are  influenced,  among  other  things,  by  changes  in  stock  prices,  market
conditions,  prevailing  interest rates and anticipation of future stock prices,
market movements or interest rate changes,  all of which in turn are affected by
economic  conditions,  such as  government  fiscal  and  monetary  policies  and
actions, and national and international political and economic events.

         At best, the correlation between changes in prices of futures contracts
and of the  securities  being  hedged  can be only  approximate.  The  degree of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indices underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and  creditworthiness  of issuers,  or  identities  of
securities comprising the index and those in the Fund's portfolio. A decision of
whether, when and how to hedge involves the exercise of skill and judgment,  and
even a well-conceived hedge may be unsuccessful to some degree because of market
behavior or unexpected interest rate trends.

         Because of the low margin deposits  required,  futures trading involves
an extremely  high degree of  leverage.  As a result,  a relatively  small price
movement in a futures contract may result in immediate and substantial  loss, as
well as gain, to the investor.  For example, if at the time of purchase,  10% of
the value of the futures  contract is deposited as margin, a 10% decrease in the
value  of the  futures  contract  would  result  in a total  loss of the  margin
deposit,  before any deduction for the  transaction  costs,  if the account were
then closed out, and a 15% decrease  would result in a loss equal to 150% of the
original  margin  deposit.  Thus,  a purchase or sale of a futures  contract may
result  in losses in excess of the  amount  invested  in the  futures  contract.
However,  the Fund would presumably have sustained comparable losses if, instead
of  entering  into the  futures  contract,  it had  invested  in the  underlying
financial  instrument.  Furthermore,  in order to be  certain  that the Fund has
sufficient assets to satisfy its obligations under a futures contract,  the Fund
will  establish a segregated  account in connection  with its futures  contracts
which will hold cash or cash equivalents  equal in value to the current value of
the underlying instruments or indices less the margins on deposit.

         Most U.S. futures  exchanges limit the amount of fluctuation  permitted
in  futures  contract  prices  during a single  trading  day.  The  daily  limit
establishes  the maximum  amount that the price of a futures  contract  may vary
either  up or down  from the  previous  day's  settlement  price at the end of a
trading  session.  Once the daily limit has been reached in a particular type of
contract,  no trades may be made on that day at a price  beyond that limit.  The
daily limit  governs only price  movement  during a  particular  trading day and
therefore  does not limit  potential  losses  because  the limit may prevent the
liquidation of unfavorable positions.  Futures contract prices have occasionally
moved to the daily limit for several  consecutive trading days with little or no
trading,   thereby  preventing  prompt  liquidation  of  futures  positions  and
subjecting some futures traders to substantial losses.

Risks of Options on Futures Contracts

         In  addition  to the  risks  described  above  for  currency  and other
financial futures contracts, there are several special risks relating to options
on futures  contracts.  The ability to establish and close out positions on such
options will be subject to the development and maintenance of a liquid secondary
market.  There is no assurance that a liquid secondary market will exist for any
particular  contract  or at any  particular  time.  The Fund  will not  purchase
options on any futures contract unless and until it believes that the market for
such options has developed  sufficiently  that the risks in connection with such
options are not greater than the risks in connection with the futures contracts.
Compared  to the use of  futures  contracts,  the  purchase  of  options on such
futures  involves less  potential risk to the Fund because the maximum amount at
risk is the premium  paid for the options  (plus  transaction  costs).  However,
there may be circumstances when the use of an option on a futures contract would
result in a loss to the Fund,  even though the use of a futures  contract  would
not, such as when there is no movement in the level of the futures contract.


                          FOREIGN CURRENCY TRANSACTIONS

         The Fund may invest in  securities  of foreign  issuers.  When the Fund
invests  in foreign  securities  they  usually  will be  denominated  in foreign
currencies and the Fund temporarily may hold funds in foreign currencies.  Thus,
the Fund's share value will be affected by changes in exchange rates.

Forward Currency Contracts

         As one way of  managing  exchange  rate  risk,  the Fund may  engage in
forward currency exchange  contracts  (agreements to purchase or sell currencies
at a specified  price and date).  Under the contract,  the exchange rate for the
transaction  (the amount of currency  the Fund will  deliver or receive when the
contract is completed) is fixed when the Fund enters into the contract. The Fund
usually will enter into these  contracts to stabilize the U.S. dollar value of a
security it has agreed to buy or sell. The Fund also may use these  contracts to
hedge the U.S.  dollar value of a security it already owns,  particularly if the
Fund  expects a  decrease  in the  value of the  currency  in which the  foreign
security is  denominated.  Although  the Fund will attempt to benefit from using
forward contracts, the success of its hedging strategy will depend on Keystone's
ability  to  predict   accurately  the  future  exchange  rate  between  foreign
currencies and the U.S. dollar. The value of the Fund's investments  denominated
in foreign  currencies will depend on the relative  strength of those currencies
and the U.S.  dollar,  and the Fund may be affected  favorably or unfavorably by
changes in the exchange rate or exchange  control  regulations  between  foreign
currencies and the dollar.  Changes in foreign currency  exchange rates also may
affect the value of dividends and interest earned,  gains and losses realized on
the sale of  securities  and net  investment  income  and gains,  if any,  to be
distributed to shareholders by the Fund.

Currency Futures Contracts

         Currency  futures  contracts are bilateral  agreements  under which two
parties agree to take or make delivery of a specified  amount of a currency at a
specified  future  time for a  specified  price.  Trading  of  currency  futures
contracts in the United States is regulated under the Commodity  Exchange Act by
the  CFTC and  NFA.  Currently,  the only  national  futures  exchange  on which
currency futures are traded is the International  Monetary Market of the Chicago
Mercantile  Exchange.  Foreign currency futures trading is conducted in the same
manner and subject to the same regulations as trading in interest rate and index
based futures. The Fund intends to engage in currency futures contracts only for
hedging  purposes,  and not for  speculation.  The Fund may enter into  currency
futures  contracts for other  purposes if authorized to do so by the Board.  The
hedging  strategies  which will be used by the Fund in  connection  with foreign
currency  futures  contracts  are similar to those  described  above for forward
foreign currency exchange contracts.

         Currently,  currency futures  contracts for the British pound sterling,
Canadian dollar, Dutch guilder, Deutsche mark, Japanese yen, Mexican peso, Swiss
franc and French  franc can be purchased  or sold for U.S.  dollars  through the
International  Monetary Market. It is expected that futures contracts trading in
additional  currencies  will be  authorized.  The  standard  contract  sizes are
L125,000  for the  pound,  125,000  for the  guilder,  mark and Swiss and French
francs,  C$100,000  for  the  Canadian  dollar,  Y12,500,000  for the  yen,  and
1,000,000 for the peso. In contrast to Forward Currency Exchange Contracts which
can be traded at any time,  only four value  dates per year are  available,  the
third Wednesday of March, June, September and December.

Foreign Currency Options Transactions

         Foreign  currency  options  (as  opposed  to  futures)  are traded in a
variety of currencies in both the United States and Europe.  On the Philadelphia
Stock Exchange,  for example,  contracts for half the size of the  corresponding
futures  contracts on the Chicago Board  Options  Exchange are traded with up to
nine months maturity in marks, sterling, yen, Swiss francs and Canadian dollars.
Options  can be  exercised  at any time during the  contract  life and require a
deposit subject to normal margin requirements.  Since a futures contract must be
exercised,  the Fund must continually make up the margin balance. As a result, a
wrong  price  move  could  result  in the Fund  losing  more  than the  original
investment as it cannot walk away from the futures  contract as it can an option
contract.

         The Fund will  purchase  call and put options and sell such  options to
terminate  an  existing  position.  Options on foreign  currency  are similar to
options on stocks  except that an option on an interest  rate and/or index based
futures  contract gives the purchaser the right, in return for the premium paid,
to purchase or sell foreign currency,  rather than to purchase or sell stock, at
a specified exercise price at any time during the period of the option.

         The  Fund  intends  to use  foreign  currency  option  transactions  in
connection with hedging strategies.

Purchase of Put Options on Foreign Currencies

         The  purchase  of  protective  put  options  on a foreign  currency  is
analagous to the purchase of  protective  puts on  individual  stocks,  where an
absolute  level of protection is sought below which no additional  economic loss
would be incurred by the Fund. Put options may be purchased to hedge a portfolio
of foreign  stocks or foreign  debt  instruments  or a position  in the  foreign
currency upon which the put option is based.

Purchase of Call Options on Foreign Currencies

         The purchase of a call option on foreign currency represents a means of
obtaining  temporary  exposure to market  appreciation  at limited  risk.  It is
analogous to the purchase of a call option on an  individual  stock which can be
used as a  substitute  for a  position  in the stock  itself.  Depending  on the
pricing of the option  compared to either the foreign  currency upon which it is
based, or upon the price of the foreign stock or foreign debt  instruments,  the
purchase  of a call option may be less risky than the  ownership  of the foreign
currency or the foreign  securities.  The Fund would purchase a call option on a
foreign  currency to hedge  against an  increase  in the  foreign  currency or a
foreign market advance when the Fund is not fully invested.

         The Fund may employ new investment techniques involving forward foreign
currency exchange  contracts,  foreign currency futures contracts and options on
foreign  currencies in order to take  advantage of new techniques in these areas
which may be  developed  from time to time and  which  are  consistent  with the
Fund's  investment  objective.  The Fund believes that no additional  techniques
have been identified for employment by the Fund in the foreseeable  future other
than those described above.

Currency Trading Risks

         Currency exchange trading may involve significant risks. The four major
types of risk the Fund faces are exchange rate risk,  interest rate risk, credit
risk and country risk.

Exchange Rate Risk

         Exchange  rate risk  results  from the  movement up and down of foreign
currency values in response to shifting market supply and demand.  When the Fund
buys or sells a  foreign  currency,  an  exposure  called  an open  position  is
created.  Until the time that  position can be "covered" by selling or buying an
equivalent amount of the same currency, the Fund is exposed to the risk that the
exchange  rate might move  against it. Since  exchange  rate changes can readily
move in one  direction,  a position  carried  overnight or over a number of days
involves  greater risk than one carried a few minutes or hours.  Techniques such
as  foreign  currency  forward  and  futures  contracts  and  options on foreign
currency are intended to be used by the Fund to reduce exchange rate risk.

Maturity Gaps and Interest Rate Risk

         Interest rate risk arises  whenever there are mismatches or gaps in the
maturity  structure of the Fund's foreign exchange currency  holdings,  which is
the total of its outstanding spot and forward or futures contracts.

         Foreign currency  transactions  often involve  borrowing short term and
lending longer term to benefit from the normal  tendency of interest rates to be
higher for longer  maturities.  However in foreign exchange  trading,  while the
maturity  pattern of interest  rates for one  currency is  important,  it is the
differential between interest rates for two currencies that is decisive.

Credit Risk

         Whenever the Fund enters into a foreign exchange  contract,  it faces a
risk,  however small, that the counterparty will not perform under the contract.
As a result  there is a credit  risk,  although  no  extension  of  "credit"  is
intended.   To  limit   credit   risk,   the  Fund   intends  to  evaluate   the
creditworthiness  of each  other  party.  The Fund does not intend to trade more
than 5% of its net assets under foreign exchange contracts with one party.

         Credit risk exists  because  the Fund's  counterparty  may be unable or
unwilling to fulfill its  contractual  obligations  as a result of bankruptcy or
insolvency or when foreign exchange controls  prohibit  payment.  In any foreign
exchange transaction,  each party agrees to deliver a certain amount of currency
to the other on a particular  date. In establishing  its hedges a Fund relies on
each contract being completed. If the contract is not performed, then the Fund's
hedge is  eliminated,  and the Fund is exposed to any changes in exchange  rates
since the contract was  originated.  To put itself in the same position it would
have  been in had the  contract  been  performed,  the Fund  must  arrange a new
transaction.  However, the new transaction may have to be arranged at an adverse
exchange  rate.  The trustee for a bankrupt  company may elect to perform  those
contracts  which are  advantageous  to the company but disclaim those  contracts
which are disadvantageous, resulting in losses to the Fund.

         Another  form of  credit  risk  stems  from the time  zone  differences
between the U.S. and foreign  nations.  If the Fund sells  sterling it generally
must pay pounds to a  counterparty  earlier in the day than it will be  credited
with  dollars  in New  York.  In the  intervening  hours,  the buyer can go into
bankruptcy or can be declared insolvent. Thus, the dollars may never be credited
to the Fund.

Country Risk

         At one time or another,  virtually  every country has  interfered  with
international  transactions in its currency.  Interference has taken the form of
regulation of the local exchange market,  restrictions on foreign  investment by
residents or limits on inflows of investment funds from abroad. Governments take
such measures for example,  to improve control over the domestic  banking system
or to  influence  the pattern of receipts  and payments  between  residents  and
foreigners.   In  those  cases,  restrictions  on  the  exchange  market  or  on
international  transactions  are intended to affect the level or movement of the
exchange rate.  Occasionally  a serious  foreign  exchange  shortage may lead to
payment  interruptions or debt servicing  delays, as well as interference in the
exchange market.  It has become  increasingly  difficult to distinguish  foreign
exchange or credit risk from country risk.

         Changes in  regulations  or  restrictions  usually do have an important
exchange  market impact.  Most  disruptive are changes in rules which  interfere
with the normal  payments  mechanism.  If  government  regulations  change and a
counterparty  is either  forbidden  to perform or is  required  to do  something
extra,  then the Fund  might be left  with an  unintended  open  position  or an
unintended  maturity  mismatch.  Dealing  with  such  unintended  long or  short
positions could result in unanticipated costs to the Fund.

         Other   changes  in  official   regulations   influence   international
investment  transactions.  If one of the factors affecting the buying or selling
of a currency changes,  the exchange rate is likely to respond.  Changes in such
controls  often are  unpredictable  and can create a  significant  exchange rate
response.

         Many major countries have moved toward  liberalization  of exchange and
payments   restrictions   in  recent  years  or  accepted  the  principle   that
restrictions  should be relaxed.  A few  industrial  countries have moved in the
other direction.  Important liberalizations were carried out by Switzerland, the
United Kingdom and Japan.  They  dismantled  mechanisms for  restricting  either
foreign exchange inflows  (Switzerland),  outflows (Britain) or elements of both
(Japan). By contrast, France and Mexico have recently tightened foreign exchange
controls.

         Overall,  many exchange markets are still heavily  restricted.  Several
countries limit access to the forward market to companies  financing  documented
export or import  transactions  in an effort to insulate  the market from purely
speculative  activities.  Some of these countries  permit local traders to enter
into forward contracts with residents but prohibit certain forward  transactions
with  nonresidents.  By  comparison,  other  countries  have strict  controls on
exchange  transactions  by  residents,  but permit  free  exchange  transactions
between local traders and non-residents. A few countries have established tiered
markets,  funneling  commercial  transactions  through one market and  financial
transactions through another. Outside the major industrial countries, relatively
free  foreign  exchange  markets  are  rare and  controls  on  foreign  currency
transactions are extensive.

         Another aspect of country risk has to do with the possibility  that the
Fund may be  dealing  with a  foreign  trader  whose  home  country  is facing a
payments  problem.  Even  though the  foreign  trader  intends to perform on its
foreign exchange contracts, the contracts are tied to other external liabilities
the country has incurred. As a result performance may be delayed, and can result
in  unanticipated  cost to the  Fund.  This  aspect of  country  risk is a major
element in the Fund's  credit  judgment as to with whom it will deal and in what
amounts.
