THE FUND
     The Fund is an open-end, diversified management investment company commonly
known as a mutual fund. The Fund was formed as a Massachusetts business trust on
October 24, 1986. 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 seeks the highest possible current income exempt from federal
income taxes, while preserving capital.

     Since the Fund considers preservation of capital as well as the level of
tax exempt income as its primary objective, the Fund may realize less income
than a fund willing to expose shareholders' capital to greater risk.

   
     The investment objective of the Fund and the requirement that the Fund
invest, under ordinary circumstances, at least 80% of its assets in federally
tax-exempt obligations are fundamental and neither may be changed without the
vote of a majority of the Fund's outstanding shares as defined in the Investment
Company Act of 1940, as amended ("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 ordinary circumstances, the Fund invests substantially all and at
least 80% of its assets in federally tax-exempt obligations, including municipal
bonds and notes and tax-exempt commercial paper obligations, that are
obligations issued by or on behalf of states, territories and possessions of the
United States ("U.S."), the District of Columbia and their political
subdivisions, agencies and instrumentalities, the interest from which is, in the
opinion of counsel to the issuers of such bonds, exempt from federal income
taxes.  Thus it is possible that up to 20% of the Fund's assets could be
invested in securiteis subject to the alternative minimum tax and/or in taxable
obligations.

     Municipal bonds include debt obligations issued by or on behalf of a
political subdivision of the U.S. or any agency or instrumentality thereof to
obtain funds for various public purposes. In addition, municipal bonds include
certain types of industrial development bonds that have been or may be issued by
or on behalf of public authorities to finance privately operated facilities.
General obligation bonds involve the credit of an issuer possessing taxing power
and are payable from the issuer's general unrestricted revenues. Their payment
may be dependent upon an appropriation by the issuer's legislative body and may
be subject to quantitative limitations on the issuer's taxing power. Limited
obligation or revenue bonds are payable only from the revenues of a particular
facility or class of facilities or, in some cases, from the proceeds of a
specific revenue source, such as the user of the facility.

   
     The Fund invests in municipal bonds only if, at the date of investment,
they are rated within the four highest grades by Standard & Poor's Corporation
("S&P") (AAA, AA, A and BBB), Moody's Investors Service ("Moody's") (Aaa, Aa, A
and BAA) or Fitch Investor Services, Inc. -- Municipal Division ("Fitch") (AAA,
AA, A and BBB) or, if not rated or rated under a different system, are of
comparable quality to obligations so rated as determined by Keystone. Securities
that are in the lowest investment grade (BBB or BAA) may have speculative
characteristics.
    

     While the Fund may invest in securities of any maturity, it is currently
expected that the Fund will not invest in securities with maturities of more
than 30 years or less than 5 years (other than certain money market securities).

   
OTHER ELIGIBLE SECURITIES

    The Fund may invest up to 20% of its assets under ordinary circumstances and
up to 100% of its assets for temporary defensive purposes in the following types
of instruments, which may not be federally tax-exempt: (1) commercial paper,
including master demand notes, that at the date of investment is rated A-1, the
highest grade given by S&P, PRIME-1, the highest grade given by Moody's or, if
not rated by such services, is issued by a company that at the date of
investment has an outstanding issue rated A or better by S&P or Moody's; (2)
obligations, including certificates of deposit and bankers' acceptances, of
banks or savings and loan associations having at least $1 billion in assets that
are members of the Federal Deposit Insurance Corporation, including U.S.
branches of foreign banks and foreign branches of U.S. banks; (3) corporate
obligations (maturing in 13 months or less) that at the date of investment are
rated A or better by S&P or Moody's; (4) obligations issued or guaranteed by the
U.S. government, its agencies or instrumentalities; and (5) qualified "private
activity" industrial development bonds, the income from which, while exempt from
federal income tax under Section 103 of the Internal Revenue Code of 1986, as
amended (the "Code"), is includable in the calculation of the federal
alternative minimum tax. It should be noted that "other eligible investments"
may not be federally tax-exempt. When the Fund is investing for temporary
defensive purposes, it is not pursuing its investment objective.
    

     The Fund may enter into repurchase and reverse repurchase agreements,
purchase and sell securities and currencies on a when issued and delayed
delivery basis, write covered call and put options and purchase call and put
options, including purchasing call or put options to close out existing
positions, and may employ new investment techniques with respect to such
options. The Fund may also engage in currency and other financial futures
contracts and related options transactions for hedging purposes and not for
speculation and may employ new investment techniques with respect to such
futures contracts and related options. In addition, the Fund may invest in
municipal obligations denominated in foreign currencies that are exempt from
federal income tax and may use subsequently developed investment techniques that
are related to any of its investment policies.

     In addition to the options and futures contracts mentioned above, only if
it is consistent with its investment objective, the Fund may also invest in
certain other types of "derivative instruments," including 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 and
the statement of additional information.

INVESTMENT RESTRICTIONS
     The Fund has adopted the fundamental restrictions summarized below, which
may not be changed without the vote of a 1940 Act Majority of the Fund's
outstanding shares. These restrictions and certain other fundamental and
nonfundamental restrictions are contained in the statement of additional
information. Unless otherwise stated, all references to the Fund's assets are in
terms of current market value.
    

     Generally, the Fund may not do the following:

   
         (1) purchase any security (other than U.S. government securities) of
     any issuer if, as a result, more than 5% of its total assets would be
     invested in securities of the issuer, except that up to 25% of its total
     assets may be invested without regard to this limit;
    

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

   
         (3) purchase any security (other than 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; and

         (4) invest more than 10% of its assets in securities with legal or
     contractual restrictions on resale or in securities for which market
     quotations are not readily available, or in repurchase agreements maturing
     in more than seven days.

     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 such securities on
its books, and (2) limiting its holdings of such securities to 15% of net
assets.

RISK FACTORS
    
GENERAL
     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.

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

FUND RISKS
     Investing in the Fund involves the risk common to investing in any
security, that is that the value of the securities held by the Fund will
fluctuate in response to changes in economic conditions or public expectations
about those securities. For example, the market value of fixed income securities
in which the Fund may invest will tend to vary inversely with changes in
prevailing interest rates, decreasing when interest rates rise and increasing
when interest rates fall. In addition, the net asset value of the Fund's shares
will change according to the market's perception of the underlying portfolio
securities of the Fund.

     By itself, the Fund does not constitute a balanced investment program. The
Fund is not designed for investors seeking capital appreciation or maximum
tax-exempt income irrespective of fluctuations in principal or marketability.
Shares of the Fund would not be suitable for tax-exempt institutions and may not
be suitable for certain retirement plans that are unable to benefit from the
Fund's federally tax-exempt dividends. In addition, the Fund may not be an
appropriate investment for entities that are "substantial users" of facilities
financed by industrial development bonds or related persons thereof.

     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.

MUNICIPAL OBLIGATIONS
     The Fund's ability to achieve its objective depends partially on the prompt
payment by issuers of the interest on and principal of the municipal bonds held
by the Fund. A moratorium, default or other nonpayment of interest or principal
when due on any municipal bond, in addition to affecting the market value and
liquidity of that particular security, could affect the market value and
liquidity of other municipal bonds held by the Fund. In addition, the market for
municipal obligations is often thin and can be temporarily affected by large
purchases and sales, including those by the Fund.

     From time to time, proposals have been introduced before the U.S. Congress
for the purpose of restricting or eliminating the federal income tax exemption
for interest on municipal obligations, and similar proposals may well be
introduced in the future. If such a proposal were enacted, the availability of
municipal obligations for investment by the Fund and the value of the Fund's
portfolio could be materially affected. In such an event, the Fund would
reevaluate its investment objective and policies and consider changes in the
structure of the Fund or dissolution.

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 portfolio 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 of the Fund is arrived at by determining the value of the Fund's
assets, subtracting its liabilities, and dividing the result by the number of
its shares outstanding.

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

     (1) municipal obligations are valued on the basis of valuations provided by
a pricing service, approved by the Fund's Board of Trustees, which uses
information with respect to transactions in bonds, quotations from bond dealers,
market transactions in comparable securities and various relationships between
securities in determining value.

   
     (2) short-term investments maturing in sixty days or less when purchased
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.
    

     (3) short-term investments maturing in more than sixty days for which
market quotations are readily available are valued at current market value.

     (4) 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.

     (5) All other investments are valued at market value or, where market
quotations are not readily available, at fair value as determined in good faith
according to procedures established by the Board of Trustees.

DIVIDENDS AND TAXES
     The Fund has qualified and intends to continue to qualify as a regulated
investment company (a "RIC") under 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 substantially all of
its net investment income and net capital gains, if any, to shareholders, it
will be relieved of any federal income tax liability.

     Any taxable distribution declared in October, November or December to
shareholders of record in such a 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 will make distributions from net investment income monthly and net
realized long-term capital gains, if any, at least annually. Shareholders
receive Fund distributions in the form of additional shares of that class of
shares upon which the dividend or distribution is based, or, at the
shareholder's option, in cash. Fund distributions in the form of additional
shares are made at net asset value without the imposition of a sales charge.
There is a possibility that shareholders may lose the tax-exempt status on
accrued income on municipal bonds if shares of the Fund are redeemed before a
dividend has been declared.

     Because Class A shares bear most of the costs of distribution of such
shares through payment of a front-end sales charge, while Class B and Class C
shares bear such expenses through a higher annual distribution fee, expenses
attributable to Class B and Class C shares will generally be higher than those
of Class A shares, and income distributions paid by the Fund with respect to
Class A shares will generally be greater than those paid with respect to Class B
and Class C shares.

     The Fund expects that substantially all of its dividends will be "exempt
interest dividends," which should be treated as excludable from federal gross
income. In order to pay exempt interest dividends, at least 50% of the value of
the Fund's assets must consist of federally tax-exempt obligations at the close
of each quarter. An exempt interest dividend is any dividend or part thereof
(other than a capital gain dividend) paid by the Fund with respect to its net
federally excludable municipal obligation interest and designated as an exempt
interest dividend in a written notice mailed to each shareholder not later than
60 days after the close of its taxable year. The percentage of the total
dividends paid by the Fund with respect to any taxable year that qualifies as
exempt interest dividends will be the same for all shareholders receiving
dividends with respect to such year. If a shareholder receives an exempt
interest dividend with respect to any share and such share is held for six
months or less, any loss on the sale or exchange of such share will be
disallowed to the extent of the exempt interest dividend amount.

     Under particularly unusual circumstances, such as when the Fund is in a
prolonged defensive investment position, it is possible that no portion of the
Fund's distributions of income to its shareholders for a fiscal year would be
exempt from federal income tax; however, the Fund does not presently anticipate
that such unusual circumstances will occur.

     Any shareholder of the Fund who may be a "substantial user" of a facility
financed with an issue of tax-exempt obligations or a "related person" to such
a user should consult his tax adviser concerning his qualification to receive
exempt interest dividends should the Fund hold obligations financing such
facility.

     Under regulations to be promulgated and to the extent attributable to
interest paid on certain "private activity" bonds, the Fund's exempt interest
dividends while otherwise tax exempt, will be treated as a tax preference item
for alternative minimum tax purposes. Corporate shareholders should also be
aware that the receipt of exempt interest dividends could subject them to
alternative minimum tax under the provisions of Section 56(g) of the Code
(relating to "adjusted current earnings").

     Since none of the Fund's income will consist of corporate dividends, no
distributions will qualify for the 70% corporate dividends received deduction.

     The Fund intends to distribute its net capital gains as capital gain
dividends. Shareholders should treat such dividends as long-term capital gains.
Such distributions will be designated as such by a written notice mailed to each
shareholder no later than 60 days after the close of the Fund's taxable year. If
a shareholder receives a capital gain dividend and holds his shares for six
months or less, then any allowable loss on disposition of such shares will be
treated as a long-term capital loss to the extent of such capital gain dividend.

     Interest on indebtedness incurred or continued by shareholders to purchase
or carry shares of the Fund will not be deductible for federal income tax
purposes to the extent of the portion of the interest expense relating to exempt
interest dividends. That portion is determined by multiplying the total amount
of interest paid or accrued on the indebtedness by a fraction, the numerator of
which is the exempt interest dividends received by a shareholder in his taxable
year and the denominator of which is the sum of the exempt interest dividends
and the taxable distributions out of the Fund's investment income and long-term
capital gains received by the shareholder.

     The Fund may acquire an option to "put" specified securities to municipal
bond dealers or issuers from whom the securities are purchased. It is expected
that the Fund will be treated for federal income tax purposes as the owner of
the municipal bonds acquired subject to the put. The interest on the municipal
bonds will be tax exempt to the Fund, and the purchase prices must be allocated
between such securities and the put based upon their respective fair market
values. The IRS has not issued a published ruling on this matter and could reach
a different conclusion.

     Some or all of the Fund's exempt interest dividends may be subject to state
income taxes. The Fund will report to shareholders on a state by state basis the
sources of its exempt interest dividends.

  The foregoing is only a summary of some of the important tax considerations
generally affecting the Fund and its shareholders. No attempt is made to present
a detailed explanation of the federal income tax treatment of the Fund or its
shareholders, and this discussion is not intended as a substitute for careful
tax planning. Accordingly, potential investors in the Fund are urged to consult
their tax advisers with specific reference to their own tax situation.

FUND MANAGEMENT AND EXPENSES
BOARD OF TRUSTEES

     Under Massachusetts law, the Fund's Board of Trustees has absolute and
exclusive control over the management and disposition of all assets of the Fund.
Subject to the authority of the 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 Keystone and First Union 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 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
Management                                                 Value of the Shares
Fee                                                                of the Fund
                                    Income
- ------------------------------------------------------------------------------
   
                                   2.0% 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 Fund's Board of Trustees or by
vote of shareholders of the Fund. In either case, the terms of the Advisory
Agreement and continuance thereof must be approved by the vote of a majority of
the Fund's Independent Trustees (Trustees who are not "interested persons" of
the Fund, as defined in the 1940 Act), cast in person at a meeting called for
the purpose of voting on such approval. The Advisory Agreement may be
terminated, without penalty, on 60 days' written notice by the Fund or Keystone
or 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. (formerly Evergreen Funds Distributor,
Inc.) ("EKD"), a subsidiary of The BISYS Group, Inc. ("BISYS") which is not
affiliated with First Union, is now the Fund's principal underwriter (the
"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 West 55th Street, New York, 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 receives a fee from Keystone at the maximum annual rate of
 .01% of the average daily net assets of the Fund. BISYS is located at 3435
Stelzer Road, Columbus, Ohio 43219.

PORTFOLIO MANAGER
     Daniel A. Rabasco, a Keystone Vice President and Portfolio Manager, has
been responsible for the day-to-day management of the Fund since January, 1996.
Mr. Rabasco joined Keystone as an Analyst in 1990, and has more than 10 years
investment experience.

FUND EXPENSES
     The Fund pays all of its expenses. In addition to the investment advisory
and distribution plan fees discussed in this prospectus, the principal expenses
that the Fund is expected to pay include, but are not limited to, fees and
expenses of its Independent Trustees; transfer, dividend disbursing, and
shareholder servicing agent expenses; custodian expenses; fees of its
independent auditors; fees of legal counsel to the Fund and its Independent
Trustees; fees payable to government agencies, including registration and
qualification fees attributable to the Fund and its shares under federal and
state securities laws; and certain extraordinary expenses. In addition, each
class will pay all of the expenses attributable to it. Such expenses are
currently limited to Distribution Plan expenses. The Fund also pays its
brokerage commissions, interest charges, and taxes.

     For the fiscal year ended November 30, 1996, the Fund paid or accrued to
Keystone Management, Inc., the Fund's former investment manager, investment
management and advisory services fees of $844,486 (0.61% of the Fund's average
daily net asset value on an annualized basis). Of such amount, $717,813 was paid
to Keystone for its services to the Fund.

     For the fiscal year ended November 30, 1996, the Fund paid or accrued
$186,105 to Evergreen Keystone Service Company (formerly Keystone Investor
Resource Center, Inc.) ("EKSC") for services rendered as the Fund's transfer
agent and dividend disbursing agent, and $21,926 to Keystone for certain
accounting services. EKSC, located at 200 Berkeley Street, Boston, Massachusetts
02116-5034, is a wholly-owned subsidiary of Keystone.

     For the fiscal year ended November 30, 1996, including indirectly paid
expenses, the Fund's Class A, Class B and Class C shares paid 1.13%, 1.90% and
1.90%, respectively, of average net assets in expenses.

SECURITIES TRANSACTIONS
     Under policies established by the Board of Trustees, Keystone selects
broker-dealers to execute transactions subject to the receipt of best execution.
When selecting broker-dealers to execute portfolio transactions for the Fund,
Keystone may consider the number of shares of the Fund sold by the
broker-dealer. In addition, broker-dealers executing portfolio transactions may,
from time to time, be affiliated with the Fund, Keystone, the 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 November 30,
1996 and 1995 were 128% and 30%, 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 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 additional information about brokerage and distributions,
see the statement of additional information.
    

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

DISTRIBUTION PLANS AND AGREEMENTS

CLASS A DISTRIBUTION PLAN
     The Fund has adopted a Distribution Plan with respect to its Class A shares
(the "Class A Distribution Plan") that provides for expenditures by the Fund
currently limited to 0.25% annually of the average daily net asset value of
Class A shares, in connection with the distribution of Class A shares. Payments
under the Class A Distribution Plan are currently made to the Principal
Underwriter (which may reallow all or part to others, such as broker-dealers),
as service fees at an annual rate of up to 0.25% of the average daily net asset
value of Class A shares maintained by the recipient and outstanding on the books
of the Fund for specified periods.

   
CLASS B DISTRIBUTION PLANS
     The Fund has adopted Distribution Plans with respect to its Class B shares
(the "Class B Distribution Plans") that provide for expenditures by the Fund at
an annual rate of up to 1.00% of the average daily net asset value of Class B
shares to pay expenses of the distribution of Class B shares. Payments under the
Class B Distribution Plans are currently made to the Principal Underwriter
(which may reallow all or part to others, such as broker-dealers) and to EKIS,
the predecessor to the Principal Underwriter, (1) as commissions for Class B
shares sold, (2) as shareholder service fees and (3) as interest. Amounts paid
or accrued to the Principal Underwriter or EKIS 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 Class B share sold. The
broker-dealer or other party will also receive service fees at an annual rate of
0.25% of the value of Class B shares maintained by the recipient and outstanding
on the books of the Fund for specified periods. See "Distribution Plans
Generally" below.

   
CLASS C DISTRIBUTION PLAN
     The Fund has adopted a Distribution Plan with respect to Class C shares
(the "Class C Distribution Plan") that provides for expenditures by the Fund at
an annual rate of up to 1.00% of the average daily net asset value of Class C
shares to pay expenses of the distribution of Class C shares. Payments under the
Class C Distribution Plan are currently made to the Principal Underwriter (which
may reallow all or part to others, such as broker-dealers) and to EKIS, the
predecessor to the Principal Underwriter, (1) as commissions for Class C shares
sold, (2) as shareholder service fees, and (3) as interest. Amounts paid or
accrued to the Principal Underwriter or EKIS in the aggregate may not exceed the
annual limitation referred to above.
    

     The Principal Underwriter generally reallows to broker-dealers or others a
commission in the amount of 0.75% of the price paid for each Class C share sold,
plus the first year's service fee in advance in the amount of 0.25% of the price
paid for each Class C share sold, and, beginning approximately fifteen months
after purchase, a commission at an annual rate of 0.75% (subject to NASD rules
- -- see "Distribution Plans Generally") plus service fees which are paid at the
annual rate of 0.25%, respectively, of the value of Class C shares maintained by
the recipient and outstanding on the books of the Fund for specified periods.
See "Distribution Plans Generally" below.

DISTRIBUTION PLANS GENERALLY
     As discussed above, the Fund bears some of the costs of selling its shares
under Distribution Plans adopted with respect to its Class A, Class B and Class
C shares pursuant to Rule 12b-1 under the 1940 Act.

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

     In connection with financing its distribution costs, including commission
advances to broker-dealers and others, EKIS, the predecessor to the Principal
Underwriter, sold to a financial institution substantially all of its 12b-1 fee
collection rights and CDSC collection rights in respect of Class B shares sold
during the period beginning approximately June 1, 1995 through November 30,
1996. The Fund has agreed not to reduce the rate of payment of 12b-1 fees in
respect of such Class B shares, unless it terminates such shares' Distribution
Plan completely. If it terminates such Distribution Plan, the Fund may be
subject to adverse distribution consequences.

     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.

     Each of the Distribution Plans may be terminated at any time by vote of the
Independent Trustees or by vote of a majority of the outstanding voting shares
of the respective class. If a Distribution Plan is terminated, the Principal
Underwriter and EKIS will ask the Independent Trustees to take whatever action
they deem appropriate under the circumstances with respect to payment of
Advances (as defined below).

   
     Unpaid distribution costs at November 30, 1996 were: $1,980,732 for Class B
shares purchased prior to June 1, 1995 (7.46% of net class assets for such Class
B shares); $371,085 for Class B shares purchased on or after June 1, 1995 5.71%
of net class assets for such Class B shares); and $2,292,841 for Class C shares
(16.65% of net class assets).
    

     Broker-dealers or others may receive different levels of compensation
depending on which class of shares they sell. Payments pursuant to a
Distribution Plan are included in the operating expenses of the class.

   
DISTRIBUTION AGREEMENTS
     The Fund has entered into principal underwriting agreements with the
Principal Underwriter (each a "Distribution Agreement") with respect to each
class. Pursuant to its Distribution Agreements, the Fund will compensate the
Principal Underwriter for its services as distributor at an annual rate that may
not exceed 0.25 of 1% of the Fund's average daily net assets attributable to
Class A shares, 0.75 of 1% of the Fund's average daily net assets attributable
to the Class B shares, subject to certain restrictions, and 0.75 of 1% of the
Fund's average daily net assets attributable to the Class C shares.

     The Fund may also make payments under its Distribution Plans, in amounts of
up to 0.25 of 1% of its average daily net assets on an annual basis,
attributable to Class A, B and C shares, respectively, to compensate
organizations, which may include, among others, the Principal Underwriter and
Keystone or their respective affiliates, for services rendered to shareholders
and/or the maintenance of shareholder accounts.

     The Fund may not pay any distribution or servicing fees during any fiscal
period in excess of NASD limits. Since the Principal Underwriter's compensation
under the Distribution Agreements is not directly tied to the expenses incurred
by the Principal Underwriter, the amount of compensation received by it under
the Distribution Agreements during any year may, subject to certain conditions,
be more than its actual expenses and may result in a profit to the Principal
Underwriter. Distribution expenses incurred by the Principal Underwriter in one
fiscal year that exceed the level of compensation paid to the Principal
Underwriter for that year may be paid from distribution fees received from the
Fund in subsequent fiscal years.
    

     The Principal Underwriter intends, but is not obligated, to continue to pay
or accrue distribution charges incurred in connection with the Class B
Distribution Plans that exceed current annual payments permitted to be received
by the Principal Underwriter from the Fund ("Advances"). The Principal
Underwriter intends to seek full reimbursement for such Advances from the Fund
(together with annual interest thereon at the prime rate plus 1%) at such time
in the future as, and to the extent that, payment thereof by the Fund would be
within the permitted limits. 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 a Distribution Plan.

   
     In states where the Principal Underwriter is not registered as a
broker-dealer, shares of the Fund will only be sold through other broker-dealers
or other financial institutions that are so registered.
    

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
     The Principal Underwriter may, from time to time, provide promotional
incentives, including reallowance of up to the entire sales charge, to certain
broker-dealers whose representatives have sold or are expected to sell
significant amounts of Fund shares. In addition, broker-dealers may, from time
to time, receive additional cash payments. The Principal Underwriter may also
provide written information to those broker-dealers with whom it has dealer
agreements that relates to sales incentive campaigns conducted by such
broker-dealers for their representatives as well as financial assistance in
connection with pre-approved seminars, conferences and advertising. No such
programs or additional compensation will be offered to the extent they are
prohibited by the laws of any state or any self-regulatory agency such as the
NASD. Broker-dealers to whom substantially the entire sales charge on Class A
shares is reallowed may be deemed to be underwriters as that term is defined
under the 1933 Act.

     The Principal Underwriter may, at its own expense, pay concessions in
addition to those described above to broker-dealers including, from time to
time, to First Union Brokerage Services, Inc., an affiliate of Keystone, 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
may, depending on the broker-dealer's satisfaction of the required conditions,
be periodic and may be up to 1.00% of the value of shares sold by such
broker-dealer.

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

     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 laws.

EFFECTS OF BANKING LAWS
     The Glass-Steagall Act currently limits the ability of depository
institutions (such as a commercial bank or a savings and loan association) to
become an underwriter or distributor of securities. In the event the Glass-
Steagall Act is deemed to prohibit depository institutions from accepting
payments under the arrangement described above, or should Congress relax current
restrictions on depository institutions, the Board of Trustees will consider
what action, if any, is appropriate.

     The Glass-Steagall Act and other banking laws and regulations also
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.

   
     Changes to applicable laws and regulations or future judicial or
administrative decisions could prevent Keystone or its affiliates from
performing the services required under the investment advisory contract or from
acting as agent in connection with the purchase of shares of a fund by its
customers. In such event, it is expected that the Trustees would identify, and
call upon each Fund's shareholders to approve, a new investment adviser. If this
were to occur, it is not anticipated that the shareholders of any Fund would
suffer any adverse financial consequences.

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
shares of the Fund 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 any amount may be made by check, by wiring Federal
funds, by direct deposit or by electronic funds transfer ("EFT").
    

     Orders for the purchase of shares of the Fund will be confirmed at the
public offering price, which is equal to the net asset value per share next
determined after receipt of the order in proper form by the Principal
Underwriter (generally as of the close of the Exchange on that day) plus, in the
case of Class A shares, the applicable sales charge. Orders received by
broker-dealers or other firms prior to the close of the Exchange and received by
the Principal Underwriter prior to the close of its business day will be
confirmed at the offering price effective as of the close of the Exchange on
that day. Broker-dealers and other financial services firms are obligated to
transmit orders promptly.

     Orders for shares received other than as stated above will receive the
public offering price, which is equal to the net asset value per share next
determined (generally, the next business day's offering price) plus, in the case
of Class A shares, the applicable sales charge.

     The Fund reserves the right to determine the net asset value more
frequently than once a day if deemed desirable.

     The initial purchase must be at least $1,000. There is no minimum amount
for subsequent purchases.

     The Fund reserves the right to withdraw all or any part of the offering
made by this prospectus, including the right to suspend sales, and to reject
purchase orders.

     Shareholder inquiries should be directed to EKSC by calling toll free
1-800- 343-2898 or writing to EKSC or to the firm from which you received this
prospectus.

ALTERNATIVE SALES OPTIONS
     This prospectus provides information regarding the Class A, B, and C shares
offered by the Fund:

CLASS A SHARES -- FRONT-END LOAD OPTION
     With certain exceptions, Class A shares are sold with a sales charge at the
time of purchase. Class A shares are not subject to a CDSC when they are
redeemed except as follows: Class A shares purchased after January 1, 1997, in
an amount equal to or exceeding $1 million, without a front-end sales charge,
will be subject to a CDSC during the month of purchase and the 12-month period
following the month of purchase.

CLASS B SHARES -- BACK-END LOAD OPTION
     Class B shares purchased after January 1, 1997, are sold without a sales
charge at the time of purchase, but are, with certain exceptions, subject to a
CDSC if redeemed during the month of purchase and the 72-month period following
the month of purchase. Class B shares purchased after January 1, 1997, that have
been outstanding for seven years after the month of purchase, will automatically
convert to Class A shares without the imposition of a front-end sales charge or
exchange fee.

CLASS C SHARES -- LEVEL LOAD OPTION
     Class C shares purchased after January 1, 1997, are sold without a sales
charge at the time of purchase, but are subject to a CDSC if they are redeemed
during the month of purchase and the 12-month period following the month of
purchase. Class C shares are available only through broker-dealers who have
entered into special distribution agreements with the Principal Underwriter.

     Each class of shares, pursuant to its Distribution Plan, pays an annual
service fee of 0.25% of the Fund's average daily net assets attributable to that
class. In addition to the 0.25% service fee, the Class B and C Distribution
Plans provide for the payment of an annual distribution fee of up to 0.75% of
the average daily net assets attributable to their respective classes. As a
result, income distributions paid by the Fund with respect to Class B and Class
C shares will generally be less than those paid with respect to Class A shares.

     Investors who would rather pay the entire cost of distribution at the time
of investment, rather than spreading such cost over time, might consider Class A
shares. Other investors might consider Class B or Class C shares (in which case,
100% of the purchase price is invested immediately), depending on the amount of
the purchase and the intended length of investment.

     The Fund will not normally accept any purchase of Class B shares in the
amount of $250,000 or more and will not normally accept any purchase of Class C
shares in the amount of $500,000 or more.

                ----------------------------------------------
CLASS A SHARES
     Class A shares are currently offered at the public offering price, which is
equal to net asset value plus an initial sales charge as follows:

     Purchases of the Fund's Class A shares made after January 1, 1997, (i) in
the amount of $1 million or more; (ii) by a corporate or certain other qualified
retirement plan or a non-qualified deferred compensation plan or a Title I tax
sheltered annuity or TSA plan sponsored by an organization having 100 or more
eligible employees (a "Qualifying Plan"), or a TSA plan sponsored by a public
educational entity having 5,000 or more eligible employees (an "Educational TSA
Plan"); or (iii) by (a) institutional investors, which may include bank trust
departments and registered investment advisers; (b) investment advisers,

trusts used to fund these plans, which place trades throught an omnibus account
maintained with the Fund by the broker-dealer; and (e) employees of FUNB and its
affiliates, EKD and any broker-dealer with whom EKD has entered into an
agreement to sell shares of the Fund, and members of the immediate families of
such employees, will each be at net asset value without the imposition of a
front-end sales charge. Certain broker-dealers or other financial institutions
may impose a fee on transactions in shares of the Fund.

     With respect to purchases of the Fund's Class A shares made after January
1, 1997, in the amount of $1 million or more, the Principal Underwriter will pay
broker-dealers or others concessions at the following rate: 1.00% of the
investment amount up to $2,999,999; plus 0.50% of the investment amount between
$3,000,000 and $4,999,999; plus 0.25% of the investment amount over $4,999,999.

   
     With respect to purchases of the Fund's Class A shares made after January
1, 1997, by Qualifying Plans and Educational TSA Plans, the Principal
Underwriter will pay broker-dealers and others concessions at the rate of 0.50%
of the net asset value of the shares purchased. These payments are subject to
reclaim in the event the shares are redeemed within twelve months after
purchase.

     Purchases of the Fund's Class A shares made after January 1, 1997, in the
amount of $1 million or more, are subject to a CDSC of 1.00% upon redemption
during the month of purchase and the 12-month period following the month of
purchase.

     The sales charge is paid to the Principal Underwriter, which in turn
normally reallows a portion to your broker-dealer. In addition, your
broker-dealer currently will be paid periodic service fees at an annual rate of
up to 0.25% of the value of Class A shares maintained by such recipient and
outstanding on the books of the Fund for specified periods.

     Upon written notice to broker-dealers with whom it has dealer agreements,
the Principal Underwriter may reallow up to the full applicable sales charge.

  Initial sales charges may be eliminated for persons purchasing Class A shares
that are offered in connection with certain fee based programs, such as wrap
accounts sponsored or managed by broker-dealers, investment advisers, or others
who have entered into special agreements with the Principal Underwriter. Initial
sales charges may be reduced or eliminated for persons or organizations
purchasing Class A shares of the Fund alone or in combination with Class A
shares of other Keystone America Funds. See Exhibit A to this prospectus.

     Upon prior notification to the Principal Underwriter, Class A shares may be
purchased at net asset value by clients of registered representatives within 30
days after a change in the registered representative's employment when the
amount invested represents redemption proceeds from a registered open-end
management investment company not distributed or managed by Keystone or its
affiliates; and the shareholder either (1) paid a front-end sales charge, or (2)
was at some time subject to, but did not actually pay, a CDSC with respect to
the redemption proceeds.

     Upon prior notification to the Principal Underwriter, Class A shares may be
purchased at net asset value by clients of registered representatives within 30
days after the redemption of shares of any registered open-end investment
company not distributed or managed by Keystone or its affiliates when the amount
invested represents redemption proceeds from such unrelated registered open-end
investment company, and the shareholder either (1) paid a front-end sales
charge, or (2) was at some time subject to, but did not actually pay, a CDSC
with respect to the redemption proceeds. This special net asset value purchase
is currently being offered on a calendar month-by-month basis and may be
modified or terminated in the future.

CLASS B SHARES
     Class B shares are offered at net asset value, without an initial sales
charge. With respect to shares purchased after January 1, 1997, the Fund, with
certain exceptions, imposes a CDSC on Class B shares redeemed as follows:

                                                                         CDSC

  period following the month of purchase ..........................      5.00%
Second twelve-month period following the month

Third twelve-month period following the month
  of purchase .....................................................      3.00%
Fourth twelve-month period following the month
  of purchase .....................................................      3.00%
Fifth twelve-month period following the month
  of purchase .....................................................      2.00%
Sixth twelve-month period following the month
  of purchase .....................................................      1.00%

No CDSC is imposed on amounts redeemed thereafter.

     When imposed, the CDSC is deducted from the redemption proceeds otherwise
payable to you. The CDSC is retained by the Principal Underwriter or its
predecessor. Amounts received by the Principal Underwriter or its predecessor
under the Class B Distribution Plans are reduced by CDSCs retained by the
Principal Underwriter or its predecessor. See "Contingent Deferred Sales Charge
and Waiver of Sales Charges" below.

   
     Class B shares purchased after January 1, 1997, that have been outstanding
for seven years after the month of purchase, will automatically convert to Class
A shares (which are subject to a lower Distribution Plan charge) without
imposition of a front-end sales charge. (Conversion of Class B shares
represented by stock certificates will require the return of the stock
certificates to EKSC.) The Class B shares so converted will no longer be subject
to the higher distribution expenses and other expenses, if any, borne by Class B
shares. Because the net asset value per share of Class A shares may be higher or
lower than that of the Class B shares at the time of conversion, although the
dollar value will be the same, a shareholder may receive more or fewer Class A
shares than the number of Class B shares converted. Under current law, it is the
Fund's opinion that such a conversion will not constitute a taxable event under
federal income tax law. In the event that this ceases to be the case, the Board
of Trustees will consider what action, if any, is appropriate and in the best
interest of such Class B shareholders.
    

CLASS C SHARES
     Class C shares are offered only through broker-dealers who have special
distribution agreements with the Principal Underwriter. Class C shares are
offered at net asset value, without an initial sales charge. With certain
exceptions, the Fund imposes a CDSC of 1.00% on shares redeemed during the month
of purchase and the 12-month period following the month of purchase. No CDSC is
imposed on amounts redeemed thereafter. If imposed, the CDSC is deducted from
the redemption proceeds otherwise payable to you. The CDSC is retained by the
Principal Underwriter or its predecessor. See "Contingent Deferred Sales Charge
and Waiver of Sales Charges" below.

CONTINGENT DEFERRED SALES CHARGE AND WAIVER OF SALES CHARGES
     Any CDSC imposed upon the redemption of Class A, Class B or Class C shares
is a percentage of the lesser of (1) the net asset value of the shares redeemed
or (2) the net asset value at the time of purchase of such shares.

     With respect to shares purchased after January 1, 1997, no CDSC is imposed
when you redeem amounts derived from (1) increases in the value of shares
redeemed above the net cost of such shares; (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; (3)
certain Class A shares held for more than 12 months after the month of purchase;
(4) Class B shares held for more than 72 months after the month of purchase; or
(5) Class C shares held for more than one year after the month of purchase. Upon
request for redemption, shares not subject to the CDSC will be redeemed first.
Thereafter, shares held the longest will be the first to be redeemed.

     With respect to Class C shares purchased by a Qualifying Plan, no CDSC will
be imposed on any redemptions made specifically by an individual participant in
the Qualifying Plan. This waiver is not available in the event a Qualifying Plan
(as a whole) redeems substantially all of its assets.

     In addition, 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 1.0% 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.

   
     The Fund may also sell Class A, Class B or Class C shares at net asset
value without any initial sales charge or a CDSC to certain Directors, Trustees,
officers and employees of the Fund, First Union Keystone, Keystone, the
Principal Underwriter and certain of their affiliates, and to members of the
immediate families of such persons; to registered representatives of firms with
dealer agreements with the Principal Underwriter; and to a bank or trust company
acting as a trustee for a single account. See the statement of additional
information.
    

HOW TO REDEEM SHARES
     You may redeem Fund shares for cash at their net redemption value by
writing to the Fund, c/o EKSC, 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. In
order to redeem by telephone or to engage in telephone transactions generally,
you must complete the authorization in your account application. Proceeds for
shares redeemed on telephone order will be deposited by wire or EFT only to the
bank account designated in your account application.

     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 per share 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. A CDSC may be imposed by the Fund at the time of redemption of
certain shares as explained in "How to Buy Shares." If imposed, the CDSC is
deducted 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 either 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 or the wiring or EFT of redemption
proceeds 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 the 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 (as described
above), 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 or EKSC may waive
this requirement or may require additional documents in certain cases.
Currently, the requirement for a signature guarantee has been waived on
redemptions of $50,000 or less when 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 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 telephone 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 Fund's 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, and written confirmation of
your transaction will be mailed the next business day. Your telephone
instructions will be recorded. Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.

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

SMALL ACCOUNTS
     Due to 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) an emergency exists and the Fund
cannot dispose of its investments or fairly determine their value; or (4) the
Securities and Exchange Commission so orders.

SHAREHOLDER SERVICES
     Details on all shareholder services may be obtained from EKSC by writing or
by calling toll free 1-800-343-2898.

KEYSTONE AUTOMATED RESPONSE LINE
     KARL offers you specific fund account information and price and yield
quotations as well as the ability to do account transactions, including
investments, exchanges and redemptions. You 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 certain other Keystone America Funds and Keystone Liquid
Trust ("KLT") as follows:

     Class A shares may be exchanged for Class A shares of other Keystone
   America Funds and Class A shares of KLT;

     Class B shares may be exchanged for the same type of Class B shares of
   other Keystone America Funds and the same type of Class B shares of KLT; and

     Class C shares may be exchanged for Class C shares of other Keystone
   America Funds and Class C shares of KLT.

     The exchange of Class B shares and Class C shares will not be subject to a
CDSC. However, if the shares being tendered for exchange are

     (1) Class A shares acquired without a front-end sales charge,

   
     (2) Class B shares that have been held for less than 72 months after the
month of purchase, or

     (3) Class C shares that have been held for less than one year after the
month of purchase, and are still subject to a CDSC, such charge will carry over
to the shares being acquired in the exchange transaction.

     You may exchange shares for another Keystone fund by calling or writing to
EKSC or by using KARL. As noted above, if the shares being tendered for exchange
are still subject to a CDSC, 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 a certain class of shares of the Fund for the
corresponding class of shares of KLT will be executed by redeeming the shares of
the Fund and purchasing the corresponding class of shares of KLT at the net
asset value of such shares next 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 day the Fund is open for business will be
executed at the respective net asset values determined as of the close of
business that 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. 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.

AUTOMATIC INVESTMENT PLAN
     With an Automatic Investment Plan, you can automatically transfer
as little as $25 per month or $75 per 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 may take up to 30 days.

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

SYSTEMATIC INCOME PLAN
     Under a Systematic Income Plan, if your account has a value of at least
$10,000, you may arrange for regular monthly or quarterly fixed withdrawal
payments. Each payment must be at least $75 and may be as much as 1.0% per month
or 3.0% per quarter of the total net asset value of the Fund shares in your
account when the Systematic Income Plan was opened. Fixed withdrawal payments
are not subject to a CDSC. Excessive withdrawals may decrease or deplete the
value of your account. Moreover, because of the effect of the applicable sales
charge, a Class A investor should not make continuous purchases of the Fund's
shares while participating in a Systematic Income Plan.

DOLLAR COST AVERAGING
     Through dollar cost averaging you can invest a fixed dollar amount each
month or each quarter in any Keystone America Fund. This results in more shares
being purchased when the selected fund's net asset value is relatively low and
fewer shares being purchased when the fund's net asset value is relatively high
and may result in a lower average cost per share than a less systematic
investment approach.

     Prior to participating in dollar cost averaging, you must establish an
account in a Keystone America Fund or a money market fund managed or advised by
Keystone. You should designate on the application (1) the dollar amount of each
monthly or quarterly investment you wish to make and (2) the fund in which the
investment is to be made. Thereafter, on the first day of the designated month,
an amount equal to the specified monthly or quarterly investment will
automatically be redeemed from your initial account and invested in shares of
the designated fund.

     If you are a Class A investor and paid a sales charge on your initial
purchase, the shares purchased will be eligible for Rights of Accumulation and
the sales charge applicable to the purchase will be determined accordingly. In
addition, the value of shares purchased will be included in the total amount
required to fulfill a Letter of Intent. If a sales charge was not paid on the
initial purchase, a sales charge will be imposed at the time of subsequent
purchases, and the value of shares purchased will become eligible for Rights of
Accumulation and Letters of Intent. See Exhibit A -- "Reduced Sales Charges" at
the back of the prospectus.

TWO DIMENSIONAL INVESTING
     You may elect to have income and capital gains distributions from any class
of Keystone America Fund shares you may own automatically invested to purchase
the same class of shares of any other Keystone America Fund. You may select this
service on your application and indicate the Keystone America Fund(s) into which
distributions are to be invested. The value of shares purchased will be
ineligible for Rights of Accumulation and Letters of Intent. See Exhibit A --
"Reduced Sales Charges" at the back of the prospectus.

OTHER SERVICES
     Under certain circumstances, you may, within 30 days after a redemption,
reinstate your account in the same class of shares that you redeemed at current
net asset value.

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

     Current yield quotations represent the yield on an investment for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum offering price per share on the last day of the
base period. Such yield will include income from sources other than municipal
obligations, if any.
    

     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.

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

     The Fund may also include comparative performance information and general
mutual fund industry information for each class of shares when advertising or
marketing the Fund's shares, such as data from Lipper Analytical Services, Inc.,
Morningstar, Inc., CDS-Weisenberger and Value Line or other financial and
industry publications.

   
FUND SHARES
     The Fund currently issues Class A, B and C shares, which participate in
dividends and distributions and have equal voting, liquidation and other rights
except that (1) expenses related to the distribution of each class of shares or
other expenses that the Board of Trustees may designate as class expenses, from
time to time, are borne solely by each class; (2) each class of shares has
exclusive voting rights with respect to its Distribution Plan; (3) each class
has different exchange privileges; and (4) each class generally has a different
designation. 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. Shares are transferable, redeemable and freely assignable
as collateral. There are no sinking fund provisions. The Fund is authorized to
issue additional series or classes of shares.
    

     Shareholders are entitled to one vote for each full share owned and
fractional votes for fractional shares. Shares of the Fund vote together except
when required by law to vote separately by class. The Fund does not have annual
meetings. The Fund will have special meetings, from time to time, as required
under its Declaration of Trust and under the 1940 Act. As provided in the Fund's
Declaration of Trust, shareholders have the right to remove Trustees by an
affirmative vote of two-thirds of the outstanding shares. A special meeting of
the shareholders will be held when holders of 10% of the outstanding shares
request a meeting. Shareholders may be eligible for shareholder communication
assistance in connection with the special meeting.

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

ADDITIONAL INFORMATION
     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 notice to those shareholders, the Fund intends, when an annual
report or a 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.

CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES
     An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in three years or less will likely receive a note
rating. Notes maturing beyond three years will most likely receive a long-term
debt rating. The following criteria are used in making that assessment:

     1. amortization schedule (the larger the final maturity relative to other
maturities the more likely it will be treated as a note); and

     2. source of payment (the more dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note).

     Note ratings are as follows:

        1. SP-1 -- Strong capacity to pay principal and interest. Those issues
     determined to possess a very strong capacity to pay debt service is given a
     plus (+) designation.

        2. SP-2 -- Satisfactory capacity to pay principal and interest, with
     some vulnerability to adverse financial and economic changes over the terms
     of the notes.

        3. SP-3 -- Speculative capacity to pay principal and interest.

B. TAX EXEMPT DEMAND BONDS
     S&P assigns "dual" ratings to all long-term debt issues that have as part
of their provisions a demand or double feature.

     The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating addresses only the demand feature. The
long-term debt rating symbols are used for bonds to denote the long-term
maturity and the commercial paper rating symbols are used to denote the put
option (for example, "AAA/A-1+"). For the newer "demand notes," S&P note
rating symbols, combined with the commercial paper symbols, are used (for
example, "SP-1+/ A-1+").

C. CORPORATE AND MUNICIPAL BOND RATINGS
     An S&P corporate or municipal 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:

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

     2. nature of and provisions of the obligation; and

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

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

     A provisional rating is sometimes used by S&P. It assumes the successful
completion of the project being financed by the debt being rated and indicates
that payment of debt service requirements is largely or entirely dependent upon
the successful and timely completion of the project. This rating, however, while
addressing credit quality subsequent to completion of the project, makes no
comment on the likelihood of, or the risk of default upon failure of, such
completion.

D. 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.

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

A. MUNICIPAL NOTES
     A Moody's rating for municipal short-term obligations will be designated
Moody's Investment Grade or (MIG). These ratings recognize the difference
between short-term credit risk and long-term risk. Factors affecting the
liquidity of the borrower and the short-term cyclical elements are critical in
short-term ratings.

     A short-term rating may also be assigned on issues with a demand feature --
variable rate demand obligation (VRDO). Such ratings will be designated as VMIG.
Short-term ratings on issues with demand features are differentiated by the use
of the VMIG symbol to reflect such characteristics as payment upon periodic
demand rather than fixed maturity dates and payment relying on the external
liquidity.

     The note ratings are as follows:

     1. MIG1/VMIG1 This designation denotes the best quality. There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broadbased access to the market for refinancing.

     2. MIG2/VMIG2 This designation denotes high quality. Margins of protection
are ample although not so large as in the preceding group.

     3. MIG3/VMIG3 This designation denotes favorable quality. All security
elements are accounted for but there is lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

     4. MIG4/VMIG4 This designation denotes adequate quality. Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

B. CORPORATE AND MUNICIPAL BOND RATINGS
     1. AAA -- Bonds 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 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 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 rated BAA are considered to be 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.

     Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from AA through BAA 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.

     CON. (--) -- Municipal bonds for which the security depends upon the
completion of some act or the fulfillment of some condition are rated
conditionally. These are bonds secured by (1) earnings of projects under
construction, (2) earnings of projects unseasoned in operation experience, (3)
rentals that begin when facilities are completed, or (4) payments to which some
other limiting condition attaches. Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

     Those municipal bonds in the AA, A, and BAA groups that Moody's believes
possess the strongest investment attributes are designated by the symbols AA 1,
A 1, and BAA 1.

FITCH CORPORATE AND MUNICIPAL RATINGS

A. MUNICIPAL NOTES
     Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally three years or less. These
include commercial paper, certificates of deposit, medium-term notes, and
municipal and investment notes. The short-term rating places greater emphasis on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

     The note ratings are as follows:

     1. F-1+ Exceptionally Strong Credit Quality. Issues assigned this rating
are regarded as having the strongest degree of assurance for timely payment.

     2. F-1 Very Strong Credit Quality. Issues assigned this rating reflect an
assurance of timely payment only slightly less in degree than issues rated F-1+.

     3. F-2 Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as great
as for issues assigned the two higher ratings.

     4. F-3 Fair Credit Quality. Issues assigned this rating have
characteristics suggesting that the degree of assurance for timely payment is
adequate, however, near-term adverse changes could cause these securities to be
rated below investment grade.

B. CORPORATE AND MUNICIPAL BOND RATINGS
AAA -- Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.

AA -- Bonds considered to be investment grade and of very high credit quality.
The obligor's ability to pay interest and repay principal is very strong,
although not quite as strong as bonds rated AAA.

A -- Bonds considered to be investment grade and of high credit quality. The
obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB -- Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be adequate. Adverse changes in economic conditions and circumstances,
however, are more likely to have adverse impact on these bonds, and therefore
impair timely payment. The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

PLUS (+) OR MINUS (-) signs are used with a rating symbol to indicate the
relative position of a credit within the rating category. Plus and minus signs,
however, are not used in the AAA category.

A CONDITIONAL rating is premised on the successful completion of a project or
the occurrence of a specific event.

     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 C1 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 bonds, and issues so rated can be regarded as
having extremely poor prospects of ever attaining any real investment standing.
Debt rated BB, B, CCC, CC, and C by Fitch is regarded as 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
represents the highest degree of speculation. Debt rated DDD, DD, and D are in
default on interest and/or principal payments.

DESCRIPTIONS 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.

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 amounts borrowed. The Fund has the right to increase the amount
under the note at any time up to the full amount provided by the note agreement,
or to decrease the amount. The borrower may repay up to the full amount of the
note without penalty. Notes acquired 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 will be deemed to
have a maturity equal to the longer of the period remaining to the next interest
rate adjustment or the demand notice period. Because these types of notes are
direct lending arrangements between the lender and 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 may 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.

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 appropriate regulatory organizations. 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 that the Fund is obligated to repurchase may decline below the
repurchase price.

"WHEN ISSUED" SECURITIES
     The Fund may also purchase and sell securities and currencies on a when
issued and delayed delivery basis. When issued or delayed delivery transactions
arise when securities or currencies are purchased or sold 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
entering into the transaction. When the Fund engages in when issued and delayed
delivery 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 and delayed delivery 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. A
separate account of liquid assets equal to the value of such purchase
commitments will be maintained until payment is made. When issued and delayed
delivery agreements 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 when issued and delayed delivery transactions, it will do so consistent with
its investment objective and policies and not for the purpose of investment
leverage.

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. Each of these uses entails greater risk than if
derivatives were used solely for hedging purposes. The Fund uses futures
contracts and related options 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 judgement, 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 objectives 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 and futures,
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
"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.

     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 a 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. To the extent permitted by its investment policies
and restrictions, 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 which 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. However, the Fund does not expect 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. To the extent permitted by its investment policies and
restrictions, the Fund may purchase put or call options, including purchasing
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 security 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 generally are
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 SEC 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 investment restriction relating to illiquid investments.

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 futures on
securities or currencies 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 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 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. The
Fund may also purchase and sell options related to foreign currencies in
connection with hedging strategies.

     VARIABLE AND 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.

     If permitted by its investment policies, 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.

     INVERSE FLOATING RATE SECURITIES. If permitted by its investment policies,
the Fund may also invest in securities with rates that move inversely to market
rates ("inverse floaters"). An inverse floater bears an interest 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.

     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 generally represent interests
in entities organized and operated solely for the purpose of restructuring the
investment characteristics of debt obligations. 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) 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.

                                                                     EXHIBIT A
                            REDUCED SALES CHARGES

     Initial sales charges may be reduced or eliminated for persons or
organizations purchasing Class A shares of the Fund alone or in combination with
Class A shares of other Keystone America Funds. Only Class A shares subject to
an initial or deferred sales charge are eligible for inclusion in reduced sales
charge programs.

     For purposes of qualifying for reduced sales charges on purchases made
pursuant to Rights of Accumulation or Letters of Intent, the term "Purchaser"
includes the following persons: an individual; an individual, his or her spouse
and children under the age of 21; a trustee or other fiduciary of a single trust
estate or single fiduciary account established for their benefit; an
organization exempt from federal income tax under Section 501 (c)(3) or (13) of
the Internal Revenue Code; a pension, profit-sharing or other employee benefit
plan whether or not qualified under Section 401 of the Internal Revenue Code; or
other organized groups of persons, whether incorporated or not, provided the
organization has been in existence for at least six months and has some purpose
other than the purchase of redeemable securities of a registered investment
company at a discount. In order to qualify for a lower sales charge, all orders
from an organized group will have to be placed through a single investment
dealer or other firm and identified as originating from a qualifying purchaser.

CONCURRENT PURCHASES
     For purposes of qualifying for a reduced sales charge, a Purchaser may
combine concurrent direct purchases of Class A shares of two or more of the
"Eligible Funds," as defined below. For example, if a Purchaser concurrently
invested $75,000 in one of the other "Eligible Funds" and $75,000 in the Fund,
the sales charge would be that applicable to a $150,000 purchase, i.e., 3.75% of
the offering price, as indicated in the Sales Charge Schedule in the prospectus.

RIGHT OF ACCUMULATION
     In calculating the sales charge applicable to current purchases of the
Fund's Class A shares, a Purchaser is entitled to accumulate current purchases
with the current value of previously purchased Class A shares of the Fund and
Class A shares of certain other eligible funds that are still held in (or
exchanged for shares of and are still held in) the same or another eligible fund
("Eligible Fund(s)"). The Eligible Funds are the Keystone America Funds and
Keystone Liquid Trust.

     For example, if a Purchaser held shares valued at $99,999 and purchased an
additional $5,000, the sales charge for the $5,000 purchase would be at the next
lower sales charge of 3.75% of the offering price as indicated in the Sales
Charge schedule. EKSC must be notified at the time of purchase that the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's holdings. The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT
     A Purchaser may qualify for a reduced sales charge on a purchase of Class A
shares of the Fund alone or in combination with purchases of Class A shares of
any of the other Eligible Funds by completing the Letter of Intent section of
the application. By so doing, the Purchaser agrees to invest within a
thirteen-month period a specified amount which, if invested at one time, would
qualify for a reduced sales charge. Each purchase will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application, as described in this prospectus. The Letter of Intent does
not obligate the Purchaser to purchase, nor the Fund to sell, the amount
indicated.

     After the Letter of Intent is received by EKSC, each investment made will
be entitled to the sales charge applicable to the level of investment indicated
on the application. The Letter of Intent may be back-dated up to ninety days so
that any investments made in any of the Eligible Funds during the preceding
ninety-day period, valued at the Purchaser's cost, can be applied toward
fulfillment of the Letter of Intent. However, there will be no refund of sales
charges already paid during the ninety-day period. No retroactive adjustment
will be made if purchases exceed the amount specified in the Letter of Intent.
Income and capital gains distributions taken in additional shares will not apply
toward completion of the Letter of Intent.

     If total purchases made pursuant to the Letter of Intent are less than the
amount specified, the Purchaser will be required to remit an amount equal to the
difference between the sales charge paid and the sales charge applicable to
purchases actually made. Out of the initial purchase (or subsequent purchases,
if necessary) 5% of the dollar amount specified on the application will be held
in escrow by EKSC in the form of shares registered in the Purchaser's name. The
escrowed shares will not be available for redemption, transfer or encumbrance by
the Purchaser until the Letter of Intent is completed or the higher sales charge
paid. All income and capital gains distributions on escrowed shares will be paid
to the Purchaser or his order.

     When the minimum investment specified in the Letter of Intent is completed
(either prior to or by the end of the thirteen-month period), the Purchaser will
be notified and the escrowed shares will be released. If the intended investment
is not completed, the Purchaser will be asked to remit to the Principal
Underwriter any difference between the sales charge on the amount specified and
on the amount actually attained. If the Purchaser does not within 20 days after
written request by the Principal Underwriter or his dealer pay such difference
in sales charge, EKSC will redeem an appropriate number of the escrowed shares
in order to realize such difference. Shares remaining after any such redemption
will be released by EKSC. Any redemptions made by the Purchaser during the
thirteen-month period will be subtracted from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed. In the
event of a total redemption of the account prior to completion of the Letter of
Intent, the additional sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

     By signing the application, the Purchaser irrevocably constitutes and
appoints EKSC his attorney to surrender for redemption any or all escrowed
shares with full power of substitution.

     The Purchaser or his dealer must inform the Principal Underwriter or EKSC
that a Letter of Intent is in effect each time a purchase is made.

                               INVESTMENT POLICIES

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

The Fund invests  primarily in municipal  bonds,  but also may invest in certain
other securities as described below.

MUNICIPAL BONDS

Municipal  bonds include debt  obligations  issued by or on behalf of a state, a
territory  or a  possession  of the United  States  ("U.S."),  the  District  of
Columbia or any political  subdivision,  agency or instrumentality  thereof (for
example,  counties, cities, towns, villages,  districts,  authorities) to obtain
funds for various public purposes, including the construction of a wide range of
public facilities, such as airports, bridges, highways, housing, hospitals, mass
transportation,  schools,  streets  and  water  and sewer  works.  Other  public
purposes  for which  municipal  bonds may be issued  include  the  refunding  of
outstanding  obligations,  obtaining  funds for general  operating  expenses and
obtaining funds to lend to public or private  institutions  for the construction
of facilities such as educational, hospital and housing facilities. In addition,
certain types of industrial  development  bonds have been or may be issued by or
on behalf of public authorities to finance certain privately-operated facilities
and certain local  facilities  for water supply,  gas,  electricity or sewage or
solid waste  disposal.  Such  obligations are included within the term municipal
bonds if the interest paid thereon qualifies as fully exempt from federal income
tax. The income of certain types of industrial development bonds used to finance
certain  privately-operated  facilities  (qualified  "private  activity"  bonds)
issued after August 7, 1986,  while exempt from federal  income tax, is included
for the purposes of the calculation of the alternative  minimum tax. Other types
of  industrial  development  bonds,  the  proceeds  of  which  are  used for the
construction,  equipment, repair or improvement of privately operated industrial
or commercial  facilities,  may constitute municipal bonds, although the current
federal tax laws place substantial limitations on the size of such issues.

The two principal  classifications  of municipal bonds are "general  obligation"
and  limited  obligation  or  "revenue"  bonds.  General  obligation  bonds  are
obligations  involving the credit of an issuer  possessing  taxing power and are
payable  from  the  issuer's  general  unrestricted  revenues  and not  from any
particular  fund or revenue  source.  Their  payment  may be  dependent  upon an
appropriation   by  the  issuer's   legislative  body  and  may  be  subject  to
quantitative  limitations on the issuer's taxing power. The  characteristics and
methods of  enforcement  of general  obligation  bonds vary according to the law
applicable to the  particular  issuer.  Limited  obligation or revenue bonds are
payable  only from the revenues  derived from a particular  facility or class of
facilities  or, in some cases,  from the  proceeds of a special  excise or other
specific  revenue  source,  such  as  the  user  of  the  facility.   Industrial
development bonds that are municipal bonds are, in most cases, revenue bonds and
generally  are not payable  from the  unrestricted  revenues of the issuer.  The
credit  quality of  industrial  development  revenue  bonds is usually  directly
related to the credit  standing  of the owner or user of the  facilities.  There
are, of course,  variations  in the security of municipal  bonds,  both within a
particular  classification  and between  classifications,  depending on numerous
factors.

The yields on municipal  bonds are dependent on a variety of factors,  including
general money market conditions,  the financial condition of the issuer, general
conditions  of the municipal  bond market,  size of a particular  offering,  the
maturity of the  obligation  and rating of the issue.  The ratings of Standard &
Poor's  Corporation  ("S&P"),  Moody's Investors  Service  ("Moody's") and Fitch
Investor Services, Inc. Municipal Division ("Fitch"), as described herein and in
the  prospectus,  represent  their  opinions as to the quality of the  municipal
bonds  that they  undertake  to rate.  It should be  emphasized,  however,  that
ratings are general and are not  absolute  standards  of quality.  Consequently,
municipal  bonds  with the same  maturity,  interest  rate and  rating  may have
different  yields while  municipal  bonds of the same maturity and interest rate
with different ratings may have the same yield. It should also be noted that the
standards of disclosure  applicable to and the amount of information relating to
the  financial  condition  of issuers of  municipal  bonds are not  generally as
extensive as those relating to corporations.

Subsequent  to its purchase by the Fund,  an issue of  municipal  bonds or other
investment  may cease to be rated or its rating may be reduced below the minimum
rating required for purchase by the Fund. Neither event requires the elimination
of such obligation from the Fund's portfolio, but Keystone will consider such an
event in its  determination  of whether  the Fund  should  continue to hold such
obligation in its portfolio.

The ability of the Fund to achieve its  investment  objective is dependent  upon
the continuing  ability of issuers of municipal bonds to meet their  obligations
to pay  interest and  principal  when due.  Obligations  of issuers of municipal
bonds,  including  municipal bonds issued by them, are subject to the provisions
of  bankruptcy,  insolvency  and other laws affecting the rights and remedies of
creditors,  such as the federal  Bankruptcy  Act, and laws,  if any, that may be
enacted by  Congress  or state  legislatures  extending  the time for payment of
principal or interest,  or both, or imposing other  constraints upon enforcement
of such  obligations.  There  is  also  the  possibility  that  as a  result  of
litigation or other conditions,  the power or ability of any one or more issuers
to pay, when due,  principal of and interest on its or their municipal bonds may
be materially  affected.  In addition,  the market for municipal  bonds is often
thin and can be  temporarily  affected by large  purchases  and sales  including
those by the Fund.

From  time to time,  proposals  have been  introduced  before  Congress  for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal bonds, and similar proposals may well be introduced in the
future.   The  enactment  of  such  a  proposal  could  materially   affect  the
availability  of municipal bonds for investment by the Fund and the value of the
Fund's  portfolio.  In which event,  the Fund would  reevaluate  its  investment
objective  and  policies and  consider  changes in the  structure of the Fund or
dissolution.

The Tax Reform Act of 1986 made significant changes in the federal tax status of
certain  obligations  that were  previously  fully  federally  tax exempt.  As a
result,  three  categories of such  obligations  issued after August 7, 1986 now
exist:  (1) "public  purpose" bonds,  the income from which remains fully exempt
from federal income tax; (2) qualified "private activity" industrial development
bonds, the income from which, while exempt from federal income tax under Section
103 of the Internal  Revenue Code,  as amended (the "Code"),  is included in the
calculation of the federal  alternative  minimum tax; and (3) "private activity"
(private purpose) bonds, the income from which is not exempt from federal income
tax. The Fund will not invest in private activity  (private purpose) bonds, and,
except as  described  under  "Other  Eligible  Securities,"  will not  invest in
qualified "private activity"  industrial  development bonds whose  distributions
are subject to the alternative minimum tax.

OTHER ELIGIBLE SECURITIES

The Fund may invest up to 20% of its assets under ordinary  circumstances and up
to 100% of its assets for temporary defensive purposes in the following types of
instruments:  (1) commercial  paper,  including master demand notes, that at the
date of investment  is rated A-1 (the highest grade given by S&P),  Prime-1 (the
highest grade given by Moody's) or, if not rated by such services,  is issued by
a company that at the date of  investment  has an  outstanding  issue rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers' acceptances, of banks or savings and loan associations, having at least
$1 billion in assets as of the date of their most recently  published  financial
statements  that are  members  of the  Federal  Deposit  Insurance  Corporation,
including U.S. branches of foreign banks and foreign branches of U.S. banks; (3)
corporate  obligations  (maturing  in 13  months  or  less)  that at the date of
investment are rated A or better by S&P or Moody's;  (4)  obligations  issued or
guaranteed  by the U.S.  government or by any agency or  instrumentality  of the
U.S.  government;  and (5) qualified "private activity"  industrial  development
bonds, the income from which, while exempt from federal income tax under Section
103 of the Code,  is included  in the  calculation  of the  federal  alternative
minimum  tax.  The Fund will assume a temporary  defensive  position  when,  for
example,  Keystone  determines that market  conditions so warrant.  If a Fund is
investing defensively it is not pursuing its objective.

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

                             INVESTMENT RESTRICTIONS

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


The  investment  restrictions  set forth  below are  fundamental  and may not be
changed  without  the vote of a majority  of the Fund's  outstanding  shares (as
defined in the  Investment  Company Act of 1940,  as amended (the "1940  Act")).
Unless otherwise  stated,  all references to the assets of the Fund are in terms
of current market value. The Fund may not do the following:

         (1) purchase any security  (other than U.S.  government  securities) of
any issuer if as a result more than 5% of its total  assets would be invested in
securities  of the  issuer,  except  that up to 25% of its total  assets  may be
invested without regard to this limit;

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

         (3) 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;

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

         (5) pledge more than 15% of its net assets to secure indebtedness;  the
purchase  or  sale  of  securities  on a  "when  issued"  basis,  or  collateral
arrangement with respect to the writing of options on securities, are not deemed
to be a pledge of assets;

         (6) issue senior  securities;  the purchase or sale of  securities on a
"when  issued" basis or  collateral  arrangement  with respect to the writing of
options on securities, are not deemed to be the issuance of a senior security;

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

         (8) purchase any security  (other than 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;

         (9) invest more than 10% of its total assets in  securities  with legal
or  contractual  restrictions  on  resale  or in  securities  for  which  market
quotations are not readily available,  or in repurchase  agreements  maturing in
more than seven days;

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

         (11) purchase securities of other investment companies,  except as part
of a merger, consolidation, purchase of assets or similar transaction;

         (12)  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 contracts and related options  transactions;
and

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

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.

For the  purpose of  limitations  1, 10 and 13, 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  multi-state  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  1 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.

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

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

                             VALUATION OF SECURITIES

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


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

         (1)  municipal  obligations  are  valued  on the  basis  of  valuations
provided by a pricing  service,  approved by the Fund's Board of Trustees  which
uses  information  with respect to transactions  in bonds,  quotations from bond
dealelrs, market transactions in comparable securities and various relationships
between securities in determining value;

         (2) short-term  investments  with maturities of sixty days or less when
purchased 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;

         (3) short-term  investments maturing in more than sixty days, for which
market quotations are readily available are valued at current market value;

         (4)  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

         (5) all other  investments  are valued at market value or, where market
quotations are not readily available,  at fair value as determined in good faith
according to procedures established by the Board of Trustees.

The Fund  believes  that reliable  market  quotations  are generally 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  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 certain 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
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.  Any securities for which market  quotations are not readily available
or other assets are valued on a consistent  basis at fair value as determined in
good faith using methods prescribed by the 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 analyses 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  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 (as defined below).
Keystone believes that the cost, value and specific application of such research
services are indeterminable and cannot be practically allocated between the Fund
and its other clients who may indirectly  benefit from the  availability of such
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.

Neither the Fund nor Keystone intends on placing  securities  transactions  with
any particular  broker.  The Fund's Board of Trustees has  determined,  however,
that the Fund may  consider  sales of Fund  shares  when  selecting  brokers  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,  the Principal  Underwriter,  or any of their affiliated
persons, as defined in the 1940 Act.

The Board of  Trustees  will,  from time to time,  review the  Fund's  brokerage
policy. Because of the possibility 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 offers three  classes of shares that differ  primarily  with respect to
sales charges and  distribution  fees. As described  below,  depending  upon the
class of shares that you purchase,  the Fund will impose a sales charge when you
purchase  Fund shares,  a contingent  deferred  sales charge (a "CDSC") when you
redeem  Fund  shares  or no sales  charges  at all.  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  Plans").  If imposed,  the Fund deducts CDSCs 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.
(the "NASD"),  paid to the Principal  Underwriter  or its  predecessor.  See the
prospectus for additional information on a particular class.

CLASS DISTINCTIONS

CLASS A SHARES With certain  exceptions,  when you purchase Class A shares after
January 1, 1997,  you will pay a maximum  sales charge of 4.75%,  payable at the
time of purchase.  (The prospectus contains a complete table of applicable sales
charges and a discussion of sales charge reductions or waivers that may apply to
purchases.)  If you purchase Class A shares in the amount of $1 million or more,
without an initial  sales  charge,  the Fund will  charge a CDSC of 1.00% if you
redeem during the month of your purchase and the 12-month  period  following the
month of your purchase.  See  "Calculation of Contingent  Deferred Sales Charge"
below.

CLASS B SHARES
The Fund  offers  Class B shares at net asset value  (without  an initial  sales
charge).  With respect to Class B shares  purchased  after January 1, 1997,  the
Fund charges a CDSC on shares redeemed as follows:

         REDEMPTION TIMING                                        CDSC RATE
         Month of purchase and the first twelve-month
              period following the month of purchase..................5.00%
         Second twelve-month
              period following the month of purchase..................4.00%
         Third twelve-month
              period following the month of purchase..................3.00%
         Fourth twelve-month
              period following the month of purchase..................3.00%
         Fifth twelve-month
              period following the month of purchase..................2.00%
         Sixth twelve-month
              period following the month of purchase..................1.00%
         Thereafter...................................................0.00%

Class B shares  purchased after January 1, 1997, that have been  outstanding for
seven years after the month of purchase,  will automatically  convert to Class A
shares  without  imposition  of  a  front-end  sales  charge  or  exchange  fee.
Conversion of Class B shares  represented by stock certificates will require the
return of the stock certificate to EKSC. See "Calculation of Contingent Deferred
Sales Charge" below.

CLASS C SHARES
Class C shares are available only through  broker-dealers  who have entered into
special distribution  agreements with EKD. The Fund offers Class C shares at net
asset value (without an initial sales charge). With certain exceptions, however,
the Fund will  charge a CDSC of 1.00%,  if you  redeem  shares  purchased  after
January  1, 1997,  during the month of your  purchase  and the  12-month  period
following the month of your purchase.  See  "Calculation of Contingent  Deferred
Sales Charge" below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

Any CDSC imposed upon the  redemption of Class A, Class B or Class C shares is a
percentage  of the lesser of (1) the net asset  value of the shares  redeemed or
(2) the net cost of such  shares.  Upon  request for  redemption,  the Fund will
redeem  shares not  subject to a CDSC  first.  Thereafter,  the Fund will redeem
shares held the longest first.

SHARES THAT ARE NOT SUBJECT TO A SALES CHARGE OR CDSC

EXCHANGES
The Fund does not charge a CDSC when you exchange  your shares for the shares of
the same class of another Keystone  America Fund. (See "Additional  Information"
for descriptions of the Keystone America Funds.) However,  if you are exchanging
shares that are still subject to a CDSC,  the CDSC will carry over to the shares
you acquire by the  exchange.  Moreover,  the Fund will  compute any future CDSC
based  upon the date you  originally  purchased  the  shares  you  tendered  for
exchange.

WAIVER OF SALES CHARGES

The Fund may sell its shares at net asset value  without an initial sales charge
to:

1.       purchasers buying shares in the amount of $1 million or more;

2.       a  corporate  or  certain  other   qualified   retirement   plan  or  a

         eligible  employees (a "Qualifying  Plan") or a TSA plan sponsored by a
         public  educational  entity having 5,000 or more eligible employees (an

         broker-dealer through whom shares are purchased;

6.       institutional  clients  of  broker-dealers,  including  retirement  and

         by the broker-dealer;

7.       employees of First Union National Bank of North  Carolina  ("FUNB") and
         its  affiliates,  EKD and any  broker-dealer  with whom EKD has entered
         into an  agreement  to sell  shares of the  Fund,  and  members  of the
         immediate families of such employees;

8.       certain Directors,  Trustees, officers employees of the Fund, Keystone,

         to this waiver is at least $500,000 and any commission paid at the time
         of such purchase is not more than 1% of the amount invested.

With  respect  to items 8 and 9 above,  the Fund will only sell  shares to these
parties  upon the  purchasers  written  assurance  that he or she is buying  the
shares  for  investment  purposes  only.  Such  purchasers  may not  resell  the
securities except through redemption by the Fund. In addition, the Fund will not
charge a CDSC on redemptions by such purchasers.

WAIVER OF CDSCS

With respect to shares purchased after January 1, 1997, the Fund does not impose
a CDSC when the shares you are redeeming represent:

1.       an increase in the value of the shares you redeem above the net cost of
         such shares;

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

                               DISTRIBUTION PLANS

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

Rule 12b-1 under the 1940 Act permits investment companies, such as the Fund, to
use their assets to bear  expenses of  distributing  their shares if they comply
with various  conditions,  including  adoption of a distribution plan containing
certain provisions set forth in Rule 12b-1 (a "Distribution Plan").

The Fund's Class A, B and C Distribution  Plans have been approved by the Fund's
Board of Trustees,  including a majority of the Trustees who are not  interested
persons  of the Fund,  as  defined  in the 1940  Act,  and who have no direct or
indirect  financial  interest in the Distribution Plans or any agreement related
thereto (the "Independent Trustees").

The NASD limits the amount that the Fund may pay annually in distribution  costs
for sale of its shares and  shareholder  service fees 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
Distribution Plan, plus interest at the prime rate plus 1% on such amounts (less
any CDSCs paid by shareholders to the Principal  Underwriter)  remaining  unpaid
from time to time.

CLASS A DISTRIBUTION PLAN

The Class A Distribution Plan provides that the Fund may expend daily amounts at
an annual rate, which is currently  limited to 0.25% of the Fund's average daily
net asset value  attributable to Class A shares, to finance any activity that is
primarily intended to result in the sale of Class A shares,  including,  without
limitation,  expenditures  consisting of payments to EKD to enable EKD to pay or
to have paid to others who sell  Class A shares a service  or other fee,  at any
such intervals as EKD may determine,  in respect of Class A shares maintained by
any such  recipient  and  outstanding  on the  books  of the Fund for  specified
periods.

Amounts paid by the Fund under the Class A Distribution  Plan are currently used
to pay others,  such as broker-dealers,  service fees at an annual rate of up to
0.25% of the average net asset value of Class A shares maintained by such others
and outstanding on the books of the Fund for specified periods.

CLASS B DISTRIBUTION PLANS

The Class B Distribution Plans provide that the Fund may expend daily amounts at
an annual  rate of up to 1.00% of the  Fund's  average  daily  net  asset  value
attributable  to  Class B shares  to  finance  any  activity  that is  primarily
intended to result in the sale of Class B shares, including, without limitation,
expenditures consisting of payments to EKD and/or its predecessor.  Payments are
made to EKD (1) to enable EKD to pay to others  (broker-dealers)  commissions in
respect of Class B shares sold since  inception of a  Distribution  Plan; (2) to
enable EKD to pay or to have paid to others a service fee, at such  intervals as
EKD may determine, in respect of Class B shares maintained by any such recipient
and  outstanding  on the  books of the Fund for  specified  periods;  and (3) as
interest.

EKD generally  reallows to  broker-dealers or others a commission equal to 4.00%
of the price paid for each Class B share sold. The  broker-dealer or other party
may also receive  service  fees at an annual rate of 0.25% of the average  daily
net  asset  value  of  such  Class  B  share  maintained  by the  recipient  and
outstanding on the books of the Fund for specified periods.

EKD intends,  but is not  obligated,  to continue to pay or accrue  distribution
charges  incurred in connection with the Class B Distribution  Plans that exceed
current  annual  payments  permitted  to  be  received  by  EKD  from  the  Fund
("Advances").  EKD intends to seek full reimbursement for Advances from the Fund
(together with annual  interest  thereon at the prime rate plus 1%) at such time
in the future as, and to the extent that,  payment  thereof by the Fund would be
within the  permitted  limits.  If the  Fund's  Independent  Trustees  authorize
reimbursement  of  Advances,  the  effect  would be to extend the period of time
during which the Fund incurs the maximum  amount of costs allowed by the Class B
Distribution Plans.

In  connection  with  financing its  distribution  costs,  including  commission
advances to broker-dealers  and others,  EKIS, the predecessor to EKD, sold to a
financial  institution  substantially all of its 12b-1 fee collection rights and
CDSC  collection  rights in  respect  of Class B shares  sold  during the period
beginning  approximately  June 1, 1995 through  November 30, 1996.  The Fund has
agreed  not to reduce the rate of payment of 12b-1 fees in respect of such Class
B shares unless it terminates such shares'  Distribution Plan completely.  If it
terminates  such  Distribution  Plans,  the  Fund  may  be  subject  to  adverse
distribution consequences.

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

CLASS C DISTRIBUTION PLAN

The Class C Distribution Plan provides that the Fund may expend daily amounts at
an annual  rate of up to 1.00% of the  Fund's  average  daily  net  asset  value
attributable  to  Class C shares  to  finance  any  activity  that is  primarily
intended to result in the sale of Class C shares, including, without limitation,
expenditures consisting of payments to EKD and/or its predecessor.  Payments are
made to EKD (1) to enable EKD to pay to others  (broker-dealers)  commissions in
respect of Class C shares sold since inception of the Distribution  Plan; (2) to
enable EKD to pay or to have paid to others a service fee, at such  intervals as
EKD may determine, in respect of Class C shares maintained by any such recipient
and  outstanding  on the  books of the Fund for  specified  periods;  and (3) as
interest.

EKD generally reallows to broker-dealers or others a commission in the amount of
0.75% of the  price  paid for each  Class C share  sold  plus the  first  year's
service fee in advance in the amount of 0.25% of the price paid for each Class C
share   sold.   Beginning   approximately   fifteen   months   after   purchase,
broker-dealers  or  others  receive  a  commission  at an  annual  rate of 0.75%
(subject  to NASD  rules)  plus  service  fees  at the  annual  rate  of  0.25%,
respectively,  of the  average  daily  net  asset  value  of each  Class C share
maintained  by the  recipient  and  outstanding  on the  books  of the  Fund for
specified periods.

DISTRIBUTION PLANS - GENERAL

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

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

Any  change  in  a  Distribution   Plan  that  would  materially   increase  the
distribution  expenses of the Fund provided for in a Distribution  Plan requires
shareholder approval.  Otherwise, a 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 each amendment.

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

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

                               INVESTMENT ADVISER

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


Subject to the general supervision of the Fund's Board of Trustees, 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.

On December 11, 1996, the predecessor  corporation to First Union Keystone, Inc.
("Keystone Investments") and indirectly each subsidiary of First Union Keystone,
including  Keystone,  were acquired (the  "Acquisition") by FUNB, a wholly-owned
subsidiary of First Union.  The predecessor  corporation to First Union Keystone
was acquired by FUNB by merger into a  wholly-owned  subsidiary  of FUNB,  which
entity  then  succeeded  to  the  business  of  the   predecessor   corporation.
Contemporaneous  with the  Acquisition,  the Fund entered into a new  investment
advisory  agreement  with Keystone and into a principal  underwriting  agreement
with EKD, an indirectly owned  subsidiary of BISYS. The new investment  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  investment  manager to the Fund,  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.  The
fee  rate  paid by the  Fund  for the  services  provided  by  Keystone  and its
affiliates has not changed as a result of the Acquisition.

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 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 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.

The Fund pays for all  charges  and  expenses,  other  than  those  specifically
referred  to as being  borne by  Keystone,  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 SEC 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;  (14)  charges and expenses of filing
annual  and  other  reports  with the SEC and  other  authorities;  and (15) all
extraordinary charges and expenses of the Fund.

The Fund pays Keystone a fee for its services at the annual rate of:

0.50%    of the first                                      $  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.

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"  as that term is defined in the
1940 Act.

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

                              PRINCIPAL UNDERWRITER

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

The  Fund  has  entered  into  Principal   Underwriting   Agreements   (each  an
"Underwriting Agreement") with EKD with respect to each class. 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  Agreements  provide
that  EKD  will  bear the  expense  of  preparing,  printing,  and  distributing
advertising and sales literature and  prospectuses  used by it. EKD or EKIS, its
predecessor,  may  receive  payments  from  the  Fund  pursuant  to  the  Fund's
Distribution Plans.

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

The Fund has agreed  under the  Underwriting  Agreements  to pay all expenses in
connection  with the  registration  of its shares with the SEC and  auditing and
filing fees in connection with the  registration of its shares under the various
state "blue-sky" laws.

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


Each  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 Fund's  Independent  Trustees,  and (ii) by vote of a majority of the Fund's
Trustees, in each case, cast in person at a meeting called for that purpose.

Each  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 subject to such agreement.  Each Underwriting  Agreement will
terminate  automatically  upon its  "assignment," as that term is defined in the
1940 Act.

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.

                              DECLARATION OF TRUST

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

MASSACHUSETTS BUSINESS TRUST

The Fund is a Massachusetts  business trust  established  under a Declaration of
Trust dated October 24, 1986, (the "Declaration of Trust").  The Fund is similar
in most respects to a business  corporation.  The principal  distinction between
the Fund and a corporation relates to the shareholder liability described below.
A copy of the  Declaration  of Trust  was  filed  as an  exhibit  to the  Fund's
Registration  Statement.  This summary is qualified in its entirety by reference
to the Declaration of Trust.

DESCRIPTION OF SHARES

The  Declaration  of Trust  authorizes  the issuance of an  unlimited  number of
shares of beneficial  interest of classes of shares, each of which represents an
equal  proportionate  interest  in the Fund with each other share of that class.
Shares are entitled upon liquidation of the Fund to a pro-rata share of the Fund
based on the relative net assets of each class.

SHAREHOLDER LIABILITY

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

VOTING RIGHTS

No amendment may be made to the Declaration of Trust that adversely  affects any
class of shares  without the approval of a majority of the shares of that class.
Shares have non-cumulative  voting rights,  which means that the holders of more
than 50% of the shares voting for the election of Trustees can elect 100% of the
Trustees  to be elected at a meeting  and,  in such  event,  the  holders of the
remaining  50% or less of the  shares  voting  will  not be  able to  elect  any
Trustees.

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

Except  as  set  forth  above,  the  Trustees  shall  continue  to  hold  office
indefinitely,  unless  otherwise  required  by law,  and may  appoint  successor
Trustees. A Trustee may be removed from or cease to hold office (as the case may
be) (1) at any time by two-thirds vote of the remaining  Trustees;  (2) when any
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 shall be liable only for his
own willful defaults and, if reasonable care has been exercised in the selection
of officers,  agents,  employees or investment advisers, shall not be liable for
any neglect or wrongdoing of any such person; provided, however, that nothing in
the  Declaration of Trust shall protect a Trustee  against any liability for his
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of his
duties.

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

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

                 STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS

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

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

The annual total  return for Class A shares of the Fund for the one-year  period
ended November 30, 1996 was (1.10%). The average annual total return for Class A
shares of the Fund for the five-year  period ended  November 30, 1996 was 5.30%.
The average annual total return for Class A shares of the Fund for the period of
February 13, 1987  (commencement  of operations) to November 30, 1996 was 6.44%.
All figures include applicable sales charges.

The average  annual total  returns for Class B shares and Class C shares for the
year ended November 30, 1996 were (0.94%) and 2.99%,  respectively.  The average
annual  total  returns for Class B and Class C for the period  from  February 1,
1993 (date of initial public  offering of Class B shares and C shares),  through
November 30, 1996 were 3.85% and 4.52%.

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 standardized yield for Class A, B
and C shares of the Fund for the 30-day  period  ended  November  30,  1996 were
4.62%, 4.10% and 4.10%, respectively.

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 federal tax  equivalent  yields for Class A, Class B and
Class C shares of the Fund for an  investor  in the 31%  federal tax bracket for
the  30-day  period  ended  November  30,  1996,  were  6.70%,  5.94% and 5.94%,
respectively.

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

REDEMPTIONS IN KIND

If conditions  arise that would make it undesirable  for the Fund to pay for all
redemptions  in cash,  the Fund may  authorized  payment to be made in portfolio
securities or other property. The Fund has obligated itself,  however, under the
1940 Act,  to redeem for cash all shares  presented  for  redemption  by any one
shareholder  up to the lesser of  $250,000 or 1% of the Fund's net assets in any
90-day period. Securities delivered in payment of redemptions would be valued at
the same value  assigned to them in computing  the net asset value per share and
would,  to the extent  permitted  by law,  be readily  marketable.  Shareholders
receiving such securities would incur brokerage costs upon the securities' sale.

GENERAL

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

No dealer,  salesman or other person is authorized to give any information or to
make any representation  not contained in the Fund's prospectus,  this statement
of additional information or in supplemental sales literature issued by the Fund
or  the  Principal  Underwriter,  and no  person  is  entitled  to  rely  on any
information or representation not contained therein.

The Fund's prospectus and this statement of additional  information omit certain
information  contained in the  registration  statement filed with the SEC, which
may be obtained from the SEC's principal office in Washington, D.C. upon payment
of the fee prescribed by the rules and regulations promulgated by the SEC.

of the Fund's outstanding Class A, B and C shares. In addition,  on February 28,
1997, Alletta Laird Downs TTEE, Alletta Laird Downs Trust, U/A DTD 03-29-89 P.O.

                                       A-1


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


                                    APPENDIX
- --------------------------------------------------------------------------------


                            MONEY MARKET INSTRUMENTS

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

COMMERCIAL PAPER

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

A.       S&P RATINGS

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

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

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

B.       MOODY'S RATINGS

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

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

         1)       leading market positions in well-established industries;

         2)       high rates of return on funds employed;

         3)       conservative capitalization structures with moderate reliance 
                  on debt and ample asset protection;

         4)       broad margins in earnings coverage of fixed financial charges 
                  and high internal cash generation; and

         5)       well established access to a range of financial markets and
                  assured sources of alternate liquidity.

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

CERTIFICATES OF DEPOSIT

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

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

         The Fund will not acquire time  deposits or  obligations  issued by the
International Bank for  Reconstruction and Development,  (the "World Bank"), the
Asian Development Bank or the Inter-American Development Bank. Additionally, the
Fund does not currently  intend to purchase  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.

U.S. GOVERNMENT SECURITIES

         Securities  issued  or  guaranteed  by the U.S.  government  include  a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities  and  dates of  issuance  and  securities  issued  by the  Government
National Mortgage  Association  ("GNMA").  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. GNMA securities include GNMA mortgage pass-through certificates.  Such
securities are supported by the full faith and credit of the U.S.

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

         Some  obligations of U.S.  government  agencies and  instrumentalities,
such as securities of Federal Home Loan Banks, are supported by the right of the
issuer to borrow from the Treasury.  Others, such as bonds issued by the Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  Because the U.S. government is not obligated by
law to provide support to an instrumentality  it sponsors,  the Fund will invest
in  the  securities  issued  by  such  an  instrumentality  only  when  Keystone
determines under standards  established by the Board of Trustees that the credit
risk with respect to the instrumentality does not make its securities unsuitable
investments. U.S. government securities do not include international agencies or
instrumentalities   in   which   the   U.S.   government,    its   agencies   or
instrumentalities participate, such as the World Bank, Asian Development Bank or
the  Inter-American  Development  Bank, or issues insured by the Federal Deposit
Insurance Corporation or Federal Savings and Loan Insurance Corporation.


                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.       MUNICIPAL NOTES

         An S&P note rating  reflects the  liquidity  concerns and market access
risks  unique to notes.  Notes due in three years or less will likely  receive a
note  rating.  Notes  maturing  beyond  three years will most  likely  receive a
long-term  debt  rating.   The  following  criteria  are  used  in  making  that
assessment:

         a.  Amortization  schedule (the larger the final  maturity  relative to
other maturities the more likely it will be treated as a note), and

         b. Source of payment (the more dependent the issue is on the market for
its refinancing, the more likely it will be treated as a note).

         Note ratings are as follows:

         1. SP-1:  Very strong or strong capacity to pay principal and interest.
Those issues determined to possess  overwhelming safety  characteristics will be
given a plus (+) designation.

         2. SP-2: Satisfactory capacity to pay principal and interest.

         3. SP-3: Speculative capacity to pay principal and interest.

B.       TAX EXEMPT DEMAND BONDS

         S&P assigns  "dual"  ratings to all long-term  debt issues that have as
part of their provisions a demand or double feature.

         The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating  addresses only the demand  feature.  The
long-term  debt  rating  symbols  are used for  bonds to  denote  the  long-term
maturity  and the  commercial  paper  rating  symbols are used to denote the put
option (for example,  "AAA/A-1+"). For the newer "demand notes," S&P note rating
symbols,  combined with the  commercial  paper  symbols,  are used (for example,
"SP-1+/A-1+").

C.       CORPORATE AND MUNICIPAL BOND RATINGS

         An S&P  corporate or municipal  bond rating is a current  assessment of
the credit worthiness 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.

         A  provisional  rating  is  sometimes  used  by  S&P.  It  assumes  the
successful  completion of the project being financed by the debt being rated and
indicates  that  payment of debt  service  requirements  is largely or  entirely
dependent upon the successful and timely completion of the project. This rating,
however,  while  addressing  credit  quality  subsequent  to  completion  of the
project,  makes no comment  on the  likelihood  of, or the risk of default  upon
failure of, such completion.

         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 a 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.

MOODY'S CORPORATE AND MUNICIPAL 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.

         Moody's applies numerical modifiers,  1, 2 and 3 in each generic rating
classification  from AA through BAA 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.

         CON.  (---) - Municipal  bonds for which the security  depends upon the
completion  of  some  act  or  the  fulfillment  of  some  condition  are  rated
conditionally.  These  are bonds  secured  by (a)  earnings  of  projects  under
construction,  (b) earnings of projects unseasoned in operation experience,  (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches.  Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

         Those  municipal  bonds  in the AA,  A,  and BAA  groups  that  Moody's
believes  possess the  strongest  investment  attributes  are  designated by the
symbols AA 1, A 1, and BAA 1.


               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 to 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 doing so,  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 that are related to
currency  and other  financial  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 that specify currencies,  financial instruments or
financially based indexes 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, 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
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
indexes 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 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 futures  are  similar to options on stocks  except that an
option on a 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,  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 currency and other  financial
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 and 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,  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 commodity  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 indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and credit  worthiness  of issuers,  or  identities of
securities  comprising the index and those in the Fund's portfolio.  In addition
futures contract  transactions involve the remote risk that a party be unable to
fulfill its obligations and that the amount of the obligation will be beyond the
ability of the clearing broker to satisfy.  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
that 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 value of a Fund share will be affected by changes in exchange rates.

FORWARD CURRENCY CONTRACTS

         As one way of  managing  exchange  rate  risk,  the Fund may enter into
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 only engage in currency futures contracts for
hedging  purposes,  and not for  speculation.  The Fund may  engage in  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  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
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 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,
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 counter party 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  credit
worthiness  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  counter  party 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 that are advantageous to the company but disclaim those contracts that
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 counter  party  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
payments  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.

                        PRINCIPAL UNDERWRITING AGREEMENT

                          KEYSTONE AMERICA FUND FAMILY

                              CLASS A AND C SHARES


         AGREEMENT  made this 11th day of December,  1996 by and between each of
the parties listed on Exhibit A attached hereto and made a part hereof, each for
itself  and not  jointly  (each a "Fund"),  and  Evergreen  Keystone  Investment
Services, Inc., a Delaware corporation ("Principal Underwriter").

         It is hereby mutually agreed as follows:

         1.  The  Fund  hereby  appoints   Principal   Underwriter  a  principal
underwriter of the Class A and Class C shares of beneficial interest of the Fund
sold prior to December 11, 1996 ("Shares") as an independent contractor upon the
terms and conditions  hereinafter set forth. Except as the Fund may from time to
time  agree,  Principal  Underwriter  will act as agent  for the Fund and not as
principal.

         2. Having assigned all rights to commission payments for Shares sold on
or after  December 1, 1996 but before  December 11, 1996 to  Evergreen  Keystone
Distributor,  Inc., Principal Underwriter will not be entitled to commissions on
such  Shares.  Principal  Underwriter  shall be entitled  to receive  commission
payments  for  sales of the  Class A and C shares  (as set  forth on  Exhibit  B
attached hereto and made a part hereof) with respect to all Class A and C shares
sold prior to December 1, 1996 and  outstanding as of the opening of business on
such date  ("Pre-Acquisition  Shares") and to receive contingent  deferred sales
charges  on  such  Pre-Acquisition  Shares  as set  forth  in the  then  current
prospectus and/or statement of additional  information of the Fund. For purposes
of this Principal Underwriting  Agreement,  Pre-Acquisition Shares shall be such
shares  which are defined in Schedule I attached  hereto as  Distributor  Shares
calculated  as though the  Distributor  Last Sale Cut-Off  Date, as such term is
defined in Schedule I, was November 30, 1996. Principal  Underwriter may reallow
all or a part of such  commissions to such brokers,  dealers or other persons as
Principal Underwriter may determine.

         3. Principal Underwriter shall not make any representations  concerning
the  Shares  except  those  contained  in the  then  current  prospectus  and/or
statement  of  additional   information  covering  the  Shares  and  in  printed
information approved by the Fund as information  supplemental to such prospectus
and statement of additional information.

         4.  Principal  Underwriter  agrees to comply with the Business  Conduct
Rules of the National Association of Securities Dealers, Inc.

         5.  The Fund  agrees  to  indemnify  and hold  harmless  the  Principal
Underwriter,  its officers and Directors  and each person,  if any, who controls
the Principal Underwriter within the meaning of Section 15 of the Securities Act
of 1933 ("1933  Act"),  against any losses,  claims,  damages,  liabilities  and
expenses (including the cost of any legal fees incurred in connection therewith)
which the Principal Underwriter, its officers, Directors or any such controlling
person may incur under the 1933 Act, under any other  statute,  at common law or
otherwise, arising out of or based upon

                  a) any untrue  statement  or  alleged  untrue  statement  of a
         material  fact  contained in the Fund's  registration  statement,  pros
         pectus or statement of additional information (including amendments and
         supplements thereto), or

                  b) any omission or alleged  omission to state a material  fact
         required to be stated in the Fund's registration statement,  prospectus
         or statement of additional information necessary to make the statements
         therein not  misleading,  provided,  however,  that  insofar as losses,
         claims, damages, liabilities or expenses arise out of or are based upon
         any such untrue  statement or omission or alleged  untrue  statement or
         omission made in reliance and in conformity with information  furnished
         to the  Fund  by  the  Principal  Underwriter  for  use  in the  Fund's
         registration   statement,   prospectus   or  statement  of   additional
         information,  such indemnification is not applicable.  In no case shall
         the Fund indemnify the Principal  Underwriter or its controlling person
         as to any amounts  incurred for any  liability  arising out of or based
         upon any action for which the Principal  Underwriter,  its officers and
         Directors  or any  controlling  person  would  otherwise  be subject to
         liability  by  reason  of  willful  misfeasance,  bad  faith  or  gross
         negligence  in  the  performance  of its  duties  or by  reason  of the
         reckless disregard of its obligations and duties under this Agreement.

         6. The Principal  Underwriter agrees to indemnify and hold harmless the
Fund,  its  officers,  Trustees and each  person,  if any, who controls the Fund
within  the  meaning of Section  15 of the 1933 Act  against  any loss,  claims,
damages, liabilities and expenses (including the cost of any legal fees incurred
in connection  therewith)  which the Fund,  its officers,  Directors or any such
controlling  person may incur under the 1933 Act,  under any other  statute,  at
common law or  otherwise  arising  out of the  acquisition  of any Shares by any
person which

                  a) may  be  based  upon  any wrongful  act  by  the  Principal
         Underwriter or any of its employees or representatives, or

                  b) may be based upon any untrue  statement  or alleged  untrue
         statement  of a material  fact  contained  in the  Fund's  registration
         statement, prospectus or statement of additional information (including
         amendments  and  supplements  thereto),  or  any  omission  or  alleged
         omission  to state a material  fact  required  to be stated  therein or
         necessary  to make  the  statements  therein  not  misleading,  if such
         statement or omission was made in reliance upon  information  furnished
         or confirmed in writing to the Fund by the Principal Underwriter.

         7.  To  the  extent  required  by the  Fund's  12b-1  Plans,  Principal
Underwriter  shall  provide to the Board of Trustees  of the Fund in  connection
with such 12b-1 Plan, not less than  quarterly,  a written report of the amounts
expended pursuant to such 12b-1 Plan and the purpose for which such expenditures
were made.

         8. The term of this  Agreement  shall  begin  on the date  hereof  and,
unless sooner terminated or continued as provided below,  shall expire after two
years.  This  Agreement  shall  continue  in  effect  after  such  term  if  its
continuance is  specifically  approved by a majority of the Trustees of the Fund
and a majority of the 12b-1 Trustees  referred to in the 12b-1 Plans of the Fund
("Rule 12b-1  Trustees") at least  annually in accordance  with the 1940 Act and
the rules and regulations thereunder.

                  This Agreement may be terminated at any time,  without payment
of any penalty, by vote of a majority of any Rule 12b-1 Trustees or by a vote of
a  majority  of the Fund's  outstanding  Shares on not more than sixty (60) days
written  notice  to any  other  party  to the  Agreement;  and  shall  terminate
automatically in the event of its assignment (as defined in the 1940 Act).

         9. This  Agreement shall  be  construed in  accordance with the laws of
The Commonwealth of Massachusetts.

         10. The Fund is a  Massachusetts  business  trust  established  under a
Declaration of Trust, as it may be amended from time to time. The obligations of

                        PRINCIPAL UNDERWRITING AGREEMENT
                              FOR CLASS B-1 SHARES
                                       OF
                            KEYSTONE WORLD BOND FUND

          AGREEMENT made this 11th day of December 1996 by and between  Keystone
World Bond  Fund,  a  Massachusetts  business  trust,  ("Fund"),  and  Evergreen
Keystone  Investment  Services,  Inc., a Delaware  corporation  (the  "Principal
Underwriter").

          The  Fund,  individually  and/or  on  behalf  of its  series,  if any,
referred to above in the title of this Agreement,  to which series, if any, this
Agreement shall relate,  as applicable (the "Fund"),  may act as the distributor
of certain securities of which it is the issuer pursuant to Rule 12b-1 under the
Investment  Company  Act of 1940 (the  "1940  Act").  Accordingly,  it is hereby
mutually agreed as follows:

          1. The Fund hereby  appoints  the  Principal  Underwriter  a principal
underwriter  of the Class B-1 shares of  beneficial  interest  of the Fund ("B-1
Shares") as an independent  contractor upon the terms and conditions hereinafter
set forth.  The general term  "Shares" as used herein has the same meaning as is
provided therefor in Schedule I hereto. Except as the Fund may from time to time
agree,  the  Principal  Underwriter  will act as  agent  for the Fund and not as
principal.

          2.  The  Principal  Underwriter  will  use its  best  efforts  to find
purchasers for the B-1 Shares and to promote  distribution of the B-1 Shares and
may obtain orders from brokers, dealers or other persons for sales of B-1 Shares
to them. No such dealer,  broker or other person shall have any authority to act
as agent for the Fund;  such  dealer,  broker or other  person shall act only as
principal in the sale of B-1 Shares.

          3. Sales of B-1 Shares by Principal Underwriter shall be at the public
offering  price  determined  in the  manner set forth in the  prospectus  and/or
statement  of  additional  information  of the Fund  current  at the time of the
Fund's  acceptance  of the order for B-2 Shares.  All orders shall be subject to
acceptance by the Fund and the Fund reserves the right in its sole discretion to
reject any order received. The Fund shall not be liable to anyone for failure to
accept any order.

          4. On all sales of B-1 Shares made prior to December  11,  1996.  Fund
shall pay the Principal Underwriter  Distribution Fees (as defined in Section 14
hereof), as commissions for the sale of B-1 Shares and other Shares, which shall
be paid in conjunction with distribution fees paid to the Principal  Underwriter
by other classes of Shares of the Fund to the extent required in order to comply
with Section 14 hereof,  and shall pay over to the Principal  Underwriter  CDSCs
(as defined in Section 14 hereof) as set forth in the Fund's current  prospectus
and statement of additional  information,  and as required by Section 14 hereof.
The Principal  Underwriter shall also receive payments consisting of shareholder
service fees ("Service Fees") at the rate of .25% per annum of the average daily
net asset value of the Class B-1 Shares  outstanding prior to December 11, 1996.
The Principal  Underwriter may allow all or a part of said Distribution Fees and
CDSCs  received  by it (not  paid to  others as  hereinafter  provided)  to such
persons as Principal  Underwriter may determine.

          5.  Payment to the Fund for B-1 Shares  shall be in New York or Boston
Clearing House funds received by the Principal Underwriter within three business
days after  notice of  acceptance  of the  purchase  order and the amount of the
applicable  public  offering  price  has been  given to the  purchaser.  If such
payment is not received within such period, the Fund reserves the right, without
further notice,  forthwith to cancel its acceptance of any such order.  The Fund
shall pay such issue  taxes as may be  required  by law in  connection  with the
issue of the B-1 Shares.

         6. The Principal  Underwriter shall not make in connection with the B-1
Shares any  representations  concerning the B-1 Shares except those contained in
the then current prospectus and/or statement of additional  information covering
the  Shares  and in  printed  information  approved  by the Fund as  information
supplemental to such prospectus and statement of additional information. [Copies
of the then current  prospectus and statement of additional  information and any
such  printed  supplemental  information  will be  supplied  by the  Fund to the
Principal Underwriter in reasonable quantities upon request.]

          7. The Principal  Underwriter  agrees to comply with the Rules of Fair
Practice of the National Association of Securities Dealers,  Inc. (as defined in
the Purchase and Sale  Agreement,  dated as of December 11, 1996 (the  "Purchase
Agreement"),  between the  Principal  Underwriter,  Citibank,  N.A. and Citicorp
North  America,  Inc.,  as agent (the  "Rules of Fair  Practice")).

          8. The Fund appoints the Principal  Underwriter as its agent to accept
orders for redemptions and repurchases of B-1 Shares at values and in the manner
determined in accordance with the then current  prospectus  and/or  statement of
additional  information  of the Fund.

          9. The Fund  agrees  to  indemnify  and hold  harmless  the  Principal
Underwriter,  its officers and Directors  and each person,  if any, who controls
the Principal Underwriter within the meaning of Section 15 of the Securities Act
of 1933 ("1933  Act"),  against any losses,  claims,  damages,  liabilities  and
expenses (including the cost of any legal fees incurred in connection therewith)
which the Principal Underwriter, its officers, Directors or any such controlling
person may incur under the 1933 Act, under any other  statute,  at common law or
otherwise, arising out of or based upon

          a.  any untrue  statement  or alleged  untrue  statement of a material
              fact contained in the Fund's registration statement, prospectus or
              statement of  additional  information  (including  amendments  and
              supplements thereto) or

          b.  any omission or alleged omission to state a material fact required
              to be stated in the Fund's registration  statement,  prospectus or
              statement  of  additional   information   necessary  to  make  the
              statements therein not misleading, provided, however, that insofar
              as losses, claims,  damages,  liabilities or expenses arise out of
              or are based upon any such untrue statement or omission or alleged
              untrue  statement or omission  made in reliance and in  conformity
              with   information   furnished  to  the  Fund  by  the   Principal
              Underwriter  for  use  in  the  Fund's   registration   statement,
              prospectus   or  statement   of   additional   information,   such
              indemnification  is not  applicable.  In no case  shall  the  Fund
              indemnify the Principal  Underwriter or its controlling  person as
              to any amounts incurred for any liability  arising out of or based
              upon any action for which the Principal Underwriter,  its officers
              and Directors or any controlling person would otherwise be subject
              to liability by reason of willful misfeasance, bad faith, or gross
              negligence  in the  performance  of its duties or by reason of the
              reckless  disregard  of its  obligations  and  duties  under  this
              Agreement.

          10. The  Principal  Underwriter  agrees to indemnify and hold harmless
the Fund,  its officers  and Trustees and each person,  if any, who controls the
Fund within the meaning of Section 15 of the 1933 Act against any loss,  claims,
damages, liabilities and expenses (including the cost of any legal fees incurred
in connection  therewith)  which the Fund,  its officers,  Directors or any such
controlling  person may incur under the 1933 Act,  under any other  statute,  at
common law or  otherwise  arising  out of the  acquisition  of any Shares by any
person which (a) may be based upon any wrongful act by the Principal Underwriter
or any of its employees or representatives,  or (b) may be based upon any untrue
statement or alleged untrue statement of a material fact contained in the Fund's
registration  statement,  prospectus  or  statement  of  additional  information
(including  amendments  and  supplements  thereto),  or any  omission or alleged
omission to state a material fact required to be stated  therein or necessary to
make the statements  therein not  misleading,  if such statement or omission was
made in reliance upon information  furnished or confirmed in writing to the Fund
by the Principal Underwriter.

          11.  The Fund  agrees to execute  such  papers and to do such acts and
things  as shall  from time to time be  reasonably  requested  by the  Principal
Underwriter  for the  purpose  of  qualifying  the B-1 Shares for sale under the
so-called  "blue sky" laws of any state or for  registering B-1 Shares under the
1933 Act or the Fund under the Investment  Company Act of 1940 ("1940 Act"). The
Principal  Underwriter  shall  bear the  expenses  of  preparing,  printing  and
distributing  advertising,  sales  literature,  prospectuses,  and statements of
additional  information.  The Fund shall bear the  expense  of  registering  B-1
Shares under the 1933 Act and the Fund under the 1940 Act, qualifying B-1 Shares
for sale under the so-called  "blue sky" laws of any state,  the preparation and
printing of  prospectuses,  statements  of  additional  information  and reports
required  to be filed with the  Securities  and  Exchange  Commission  and other
authorities,   the  preparation,   printing  and  mailing  of  prospectuses  and
statements of additional  information  to holders of B-1 Shares,  and the direct
expenses of the issue of B-1 Shares.

          The Principal  Underwriter  shall, at the request of the Fund, provide
to the Board of Trustees or Directors  (together  herein called the "Directors")
of the Fund in  connection  not less  than  quarterly  a  written  report of the
amounts  received  from  the Fund  hereunder  and the  purpose  for  which  such
expenditures by the Fund were made.

          The term of this Agreement  shall begin on the date hereof and, unless
sooner  terminated or continued as provided below,  shall expire after one year.
This Agreement  shall  continue in effect after such term if its  continuance is
specifically  approved by a majority of the  outstanding  voting  securities  of
Class  B-1 of the  Fund or by a  majority  of the  Directors  of the  Fund and a
majority of the Directors who are not parties to this  Agreement or  "interested
persons",  as defined in the Investment Company Act of 1940 (the "1940 Act"), of
any such  party and who have no direct or  indirect  financial  interest  in the
operation  of the  Fund's  Rule  12b-1  plan  for  Class  B-1  Shares  or in any
agreements related to the plan at least annually in accordance with the 1940 Act
and the rules and regulations thereunder.

          This Agreement may be terminated at any time,  without  payment of any
penalty,  by vote of a majority of the  Directors of the Fund,  or a majority of
such Directors who are not parties to this Agreement or "interested persons", as
defined in the 1940 Act,  of any such  party and who have no direct or  indirect
financial  interest in the operation of the Fund's Rule 12b-1 plan for Class B-1
Shares or in any agreement related to the plan or by a vote of a majority of the
outstanding  voting  securities of Class B-1 on not more than sixty days written
notice to any other party to the agreement; and shall terminate automatically in
the event of its  assignment  (as  defined  in the 1940  Act),  which  shall not
include  assignment  of the Principal  Underwriter's  (as  hereinafter  defined)
provided for hereunder and/or rights related to such Allocable Portions.

          14.  The  provisions  of this  Section 14 shall be  applicable  to the
extent necessary to enable the Fund to comply with the obligation of the Fund to
pay the Principal Underwriter its Allocable Portion of Distribution Fees paid in
respect of Shares while the Fund is required to do so pursuant to the  Principal
Underwriting  Agreement,  of even date herewith, in respect of Class B-2 Shares,
and shall  remain in effect so long as any  payments  are required to be made by
the Fund  pursuant to the  irrevocable  payment  instruction  (as defined in the
Purchase Agreement (the "Irrevocable Payment Instruction")).

          14.1 The Fund shall pay to the  Principal  Underwriter  the  Principal
Underwriter's   Allocable  Portion  (as  hereinafter  defined)  of  a  fee  (the
"Distribution Fee") at the rate of .75% per annum of the average daily net asset
value of the Fund  Shares  sold  prior to  December  11,  1996,  subject  to the
limitation on the maximum  aggregate amount of such fees under the Rules of Fair
Practice as applicable to such Distribution Fee on the date hereof.

          14.2 The Principal  Underwriter's  Allocable  Portion of  Distribution
Fees paid by the Fund in respect of Shares sold prior to December 11, 1996 shall
be equal to the portion of the Asset Based Sales Charge allocable to Distributor
Shares (as defined in Schedule I hereto to this  Agreement) in  accordance  with
Schedule I hereto.  The Fund agrees to cause its transfer  agent to maintain the
records and  arrange for the  payments on behalf of the Fund at the times and in
the amounts and to the accounts  required by Schedule I hereto,  as the same may
be amended from time to time.  It is  acknowledged  and agreed that by virtue of
the operation of Schedule I hereto the Principal Underwriter's Allocable Portion
of Distribution  Fees paid by the Fund in respect of Shares,  may, to the extent
provided in Schedule I hereto,  take into account  Distribution  Fees payable by
the Fund in respect of other existing  classes  and/or  sub-classes of shares of
the Fund which would be treated as "Shares"  under  Schedule I hereto.  The Fund
will limit amounts paid to any subsequent  principal  underwriters  of Shares to
the portion of the Asset Based Sales  Charge paid in respect of Shares  which is
allocable  to  Post-distributor  Shares  (as  defined  in  Schedule I hereto) in
accordance  with  Schedule  I  hereto.  The  Fund's  payments  to the  Principal
Underwriter in  consideration of its services in connection with the sale of B-1
Shares  made  prior  to  December  11,  1996  shall  be  the  Distribution  Fees
attributable to B-1 Shares sold prior to December 11, 1996 which are Distributor
Shares (as defined in Schedule I hereto) and all other amounts  constituting the
Principal  Underwriter's  Allocable  Portion of  Distribution  Fees shall be the
Distribution  Fees  related to the sale of other  Shares  which are  Distributor
Shares (as defined in Schedule I hereto).

          The Fund shall cause its  transfer  agent and  sub-transfer  agents to
withhold  from  redemption  proceeds  payable to holders of Shares on redemption
thereof the contingent deferred sales charges payable upon redemption thereof as
set  forth  in the  then  current  prospectus  and/or  statement  of  additional
information of the Fund  ("CDSCs") and to pay over to the Principal  Underwriter
The Principal  Underwriter's  Allocable Portion of said CDSCs paid in respect of
Shares  which shall be equal to the portion  thereof  allocable  to  Distributor
Shares (as defined in Schedule I hereto) in accordance with Schedule I hereto.

          14.3 The Principal  Underwriter shall be considered to have completely
earned the right to the payment of its Allocable Portion of the Distribution Fee
and the right to  payment  over to it of its'  Allocable  Portion of the CDSC in
respect of Shares as provided for hereby upon the completion of the sale of each
Commission  Share (as  defined  in  Schedule I hereto)  taken into  account as a
Distributor Share in computing the Principal  Underwriter's Allocable Portion in
accordance with Schedule I hereto.

          14.4  Except  as  provided  in  Section  14.5  hereof  in  respect  of
Distribution Fees only, the Fund's  obligation to pay the Principal  Underwriter
the  Distribution  Fees  and to pay  over  to the  Principal  Underwriter  CDSCs
provided for hereby shall be absolute and unconditional and shall not be subject
to dispute, offset,  counterclaim or any defense whatsoever (it being understood
that nothing in this sentence  shall be deemed a waiver by the Fund of its right
separately  to pursue any claims it may have against the  Principal  Underwriter
and  enforce  such  claims   against  any  assets   (other  than  the  Principal
Underwriter's  right to its Allocable Portion of the Distribution Fees and CDSCs
(the "Collection Rights") of the Principal Underwriter).

          14.5 Notwithstanding  anything in this Agreement to the contrary,  the
Fund  shall  pay  to  the  Principal   Underwriter  its  Allocable   Portion  of
Distribution  Fees  provided  for  hereby  notwithstanding  its  termination  as
Principal  Underwriter  for the Shares or any  termination of this Agreement and
such payment of such  Distribution  Fees, and that  obligation and the method of
computing such payment,  shall not be changed or terminated except to the extent
required by any change in applicable law,  including,  without  limitation,  the
1940 Act,  the Rules  promulgated  thereunder  by the  Securities  and  Exchange
Commission and the Rules of Fair  Practice,  in each case enacted or promulgated
after June 1, 1995, or in connection with a Complete Termination (as hereinafter
defined).  For the purposes of this Section 14.5, "Complete Termination" means a
termination of the Fund's Rule 12b-1 plan for B-2 Shares involving the cessation
of  payments  of the  Distribution  Fees,  and  the  cessation  of  payments  of
distribution  fees pursuant to every other Rule 12b-1 plan of the Fund for every
existing or future  B-Class-of-Shares  (as  hereinafter  defined) and the Fund's
discontinuance of the offering of every existing or future  B-Class-of-  Shares,
which  conditions  shall be deemed  satisfied  when they are first complied with
hereafter and so long  thereafter as they are complied with prior to the earlier
of (i) the date upon which all of the B-2 Shares  which are  Distributor  Shares
pursuant to Schedule I hereto shall have been redeemed or converted or (ii) June
1, 2005.  For purposes of this Section 14.5, the term B-Class-  of-Shares  means
each of the B-1 Class of Shares of the Fund, the B-2 Class of Shares of the Fund
and each  other  class of shares of the Fund  hereafter  issued  which  would be
treated as Shares  under  Schedule I hereto or which has  substantially  similar
economic characteristics to the B-1 or B-2 Classes of Shares taking into account
the  total  sales  charge,  CDSC or other  similar  charges  borne  directly  or
indirectly by the holder of the shares of such class. The parties agree that the
existing  C Class of  Shares  of the Fund  does not have  substantially  similar
economic characteristics to the B-1 or B-2 Classes of Shares taking into account
the  total  sales  charge,  CDSC or other  similar  charges  borne  directly  or
indirectly by the holder of such shares.  For purposes of clarity the parties to
this agreement  hereby state that they intend that a new installment  load class
of shares which may be  authorized  by amendments to Rule 6(c)-10 under the 1940
Act  will  be  considered  to  be  a   B-Class-of-Shares   if  it  has  economic
characteristics  substantially  similar to the economic  characteristics  of the
existing B-1 or B-2 Classes of Shares taking into account the total sale charge,
CDSC or other similar charges borne directly or indirectly by the holder of such
shares and will not be considered to be a  B-Class-of-Shares  if it has economic
characteristics  substantially  similar to the economic  characteristics  of the
existing  C Class of shares of the Fund  taking  into  account  the total  sales
charge, CDSC or other similar charges borne directly or indirectly by the holder
of such shares.

          14.6 The  Principal  Underwriter  may assign any part of its Allocable
Portions  and  obligations  of the Fund related  thereto (but not the  Principal
Underwriter's  obligations  to the Fund  provided for in this  Agreement) to any
person (an "Assignee") and any such assignment shall be effective as to the Fund
upon written  notice to the Fund by the  Principal  Underwriter.  In  connection
therewith  the Fund shall pay all or any  amounts  in  respect of its  Allocable
Portions  directly  to the  Assignee  thereof  as  directed  in a writing by the
Principal Underwriter in the Irrevocable Payment Instruction, as the same may be
amended  from time to time with the  consent of the Fund,  and the Fund shall be
without liability to any person if it pays such amounts when and as so directed,
except for  underpayments of amounts actually due, without any amount payable as
consequential  or other damages due to such  underpayment  and without  interest
except to the  extent  that  delay in  payment  of  Distribution  Fees and CDSCs
results in an increase in the maximum Sales Charge  allowable under the Rules of
Fair  Practice,  which  increases  daily at a rate of prime plus one percent per
annum.

          14.7 The Fund will not, to the extent it may otherwise be empowered to
do so,  change or waive any CDSC with respect to B-1 Shares,  except as provided
in the Fund's  prospectus  or statement of  additional  information  without the
Principal  Underwriter's or Assignee's consent,  as applicable.  Notwithstanding
anything to the contrary in this Agreement or any  termination of this Agreement
or the  Principal  Underwriter  as principal  underwriter  for the Shares of the
Fund,  the  Principal  Underwriter  shall be entitled  to be paid its  Allocable
Portion of the CDSCs whether or not the Fund's Rule 12b-1 plan for B-1 Shares is
terminated and whether or not any such termination is a Complete Termination, as
defined above.

          15. This Agreement  shall be construed in accordance  with the laws of
The Commonwealth of Massachusetts. All sales hereunder are to be made, and title
to the Shares shall pass, in Boston, Massachusetts.

          16. The Fund is a  Massachusetts  business trust  established  under a
Declaration of Trust, as it may be amended from time to time. The obligations of
the Fund are not personally  binding upon, nor shall recourse be had against the
private property of any of the Trustees,  shareholders,  officers,  employees or
agents of the Fund, but only the property of the Fund shall be bound.

records  of which will be kept in  accordance  with this  Schedule  I. Each such

Purchase;  provided,  that  until  the  Sub-transfer  Agent in respect of the ML

foregoing requirements,  such Sub-transfer Agent shall maintain daily records of
Sub-shareholder  Accounts  which  identify  each  Commission  Share of such Fund
reflected in such Sub-shareholder Account by the Date of Original Purchase. Each
such  Commission  Share shall be identified  as either a Distributor  Share or a
Post-distributor  Share  based  upon the  Month  of  Original  Purchase  of such
Commission  Share (or in the case of a  Sub-shareholder  Account  within  the ML
Omnibus Account, based upon the Date of Original Purchase).

          (3) Free Shares.  The Transfer  Agent shall  maintain daily records of
each Shareholder  Account (other than an Omnibus Account) in respect of any Fund
so as to identify each Free Share  (including each Special Free Share) reflected
in such  Shareholder  Account  by the Month of  Original  Purchase  of such Free
Share.  In addition,  the  Transfer  Agent shall  require that each  Shareholder
Account  (other  than an  Omnibus  Account)  have in effect  separate  elections

Dividends  or such  Shareholder  Account  shall  have  elected to have all Other

respect of each Omnibus Account maintain daily records for each  Sub-shareholder
Account in the manner  described  in the  immediately  preceding  paragraph  for
Shareholder  Accounts (other than Omnibus  Accounts);  provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer   Agent  shall  not  be  obligated  to  conform  to  the  foregoing
requirements.  Each  Sub-shareholder  Account shall also have in effect Dividend
reinvestment elections as described in the immediately preceding paragraph.

          The  Transfer  Agent  and each  Sub-transfer  Agent in  respect  of an
Omnibus Account shall identify each Free Share as either a Distributor  Share or
a Post-distributor  Share based upon the Month of Original Purchase of such Free
Share; provided,  that until the Sub-transfer Agent in respect of the ML Omnibus
Account  develops the data  processing  capability  to conform to the  foregoing
requirements,  the  Transfer  Agent shall  require  such  Sub-transfer  Agent to
identify  each  Free  Share  of a given  Fund  in the ML  Omnibus  Account  as a
Distributor Share, or Post-distributor Share, as follows:

                  in connection  with the conversion of such Shares into a class
                  A share of such  Fund)  from  the ML  Omnibus  Account  in any
                  calendar month (or portion thereof) after the Distributor Last
                  Sale  Cut-off  Date  for such  Fund  shall  be  identified  as
                  Post-distributor Shares in a number computed as follows:

                  A  X  (B/C)

                  where:

                  A        =  Free  Shares  of  such  Fund  which  are  redeemed
                           (whether or not in  connection  with an exchange  for
                           Free Shares of another Fund or in connection with the
                           conversion  of such  Shares  into a class A share  of
                           such Fund) from the ML Omnibus  Account  during  such
                           calendar month (or portion thereof)

                  B        = Free Shares of such Fund in the ML Omnibus  Account
                           identified as Post-distributor Shares and outstanding
                           as of the  close of  business  on the last day of the
                           immediately preceding calendar month.

                  C        = Total  number of Free Shares of such Fund in the ML
                           Omnibus  Account and  outstanding  as of the close of
                           business on the last day of the immediately preceding
                           calendar month.

          (4) Appreciation  Amount and Cost  Accumulation  Amount.  The Transfer
Agent shall  maintain on a daily  basis in respect of each  Shareholder  Account
(other than Omnibus Accounts) a Cost Accumulation  Amount representing the total
of the  Original  Purchase  Amounts  paid by such  Shareholder  Account  for all
Commission  Shares  reflected  in such  Shareholder  Account  as of the close of
business on each day. In addition,  the Transfer Agent shall maintain on a daily
basis in respect of each  Shareholder  Account  (other  than  Omnibus  Accounts)
sufficient  records  to enable it to  compute,  as of the date of any  actual or
deemed  redemption  or Free  Exchange of a  Commission  Share  reflected in such
Shareholder  Account an amount (such amount an  "Appreciation  Amount") equal to
the  excess,  if any, of the Net Asset Value as of the close of business on such
day of the Commission  Shares  reflected in such  Shareholder  Account minus the
Cost  Accumulation  Amount as of the close of business on such day. In the event
that a Commission Share (or portion thereof) reflected in a Shareholder  Account
is redeemed or under these rules is deemed to have been  redeemed  (whether in a
Free  Exchange  or  otherwise),  the  Appreciation  Amount for such  Shareholder
Account shall be reduced,  to the extent thereof,  by the Net Asset Value of the
Commission  Share (or portion thereof)  redeemed,  and if the Net Asset Value of
the Commission  Share (or portion  thereof) being redeemed equals or exceeds the
Appreciation  Amount, the Cost Accumulation Amount will be reduced to the extent
thereof, by such excess. If the Appreciation Amount for such Shareholder Account
immediately  prior to any redemption of a Commission  Share (or portion thereof)
is equal to or greater  than the Net Asset  Value of such  Commission  Share (or
portion  thereof) deemed to have been tendered for redemption,  no CDSCs will be
payable in respect of such Commission Share (or portion thereof).

          The  Transfer  Agent  shall  require  that the  Sub-transfer  Agent in
respect of each  Omnibus  Account  maintain  on a daily basis in respect of each
Sub-shareholder  Account  reflected in such Omnibus Account a Cost  Accumulation
Amount and  sufficient  records to enable it to  compute,  as of the date of any
actual or deemed  redemption or Free Exchange of a Commission Share reflected in
such  Sub-shareholder  Account an  Appreciation  Amount in  accordance  with the
preceding paragraph and to apply the same to determine whether a CDSC is payable
(as though such Sub-shareholder Account were a Shareholder Account other than an
Omnibus Account;  provided, that until the Sub- transfer Agent in respect of the
ML Omnibus  Account  develops the data  processing  capability to conform to the
foregoing  requirements,   such  Sub-transfer  Agent  shall  maintain  for  each
Sub-shareholder  Account a  separate  Cost  Accumulation  Amount  and a separate
Appreciation  Amount for each Date of Original  Purchase of any Commission Share
which shall be applied as set forth in the  preceding  paragraph as if each Date
of Original Purchase were a separate Month of Original Purchase.

          (5) NASD Cap. On the date the distribution fees paid in respect of any
class of  Shares  equals  the  maximum  amount  thereon  under the Rules of Fair
Practice, in respect of such class, all outstanding Shares of such class of such
Fund shall be  converted  into Class A shares of such Fund and will be deemed to
have been redeemed for their Net Asset Value for purposes of this Schedule I.

          (6) Identification of Redeemed Shares. If a Shareholder Account (other
than an Omnibus Account) tenders a Share of a Fund for redemption (other than in
connection  with an  exchange  of such Share for a Share of  another  Fund or in
connection with the conversion of such Share pursuant to a Conversion  Feature),
such  tendered  Share  will be deemed  to be a Free  Share if there are any Free
Shares reflected in such Shareholder  Account  immediately prior to such tender.
If there is more  than one Free  Share  reflected  in such  Shareholder  Account
immediately  prior to such tender,  such tendered Share will be deemed to be the
Free Share with the earliest  Month of Original  Purchase.  If there are no Free
Shares reflected in such Shareholder  Account  immediately prior to such tender,
such tendered Share will be deemed to be the Commission  Share with the earliest
Month of Original Purchase reflected in such Shareholder Account.

          If a Sub-shareholder Account reflected in an Omnibus Account tenders a
Share for  redemption  (other than in connection  with an Exchange of such Share
for a Share of another Fund or in connection  with the  conversion of such Share
pursuant to a Conversion  Feature),  the Transfer  Agent shall  require that the
record  owner of each  Omnibus  Account  supply the  Transfer  Agent  sufficient
records  to  enable  the  Transfer  Agent to apply  the  rules of the  preceding
paragraph  to such  Sub-shareholder  Account  (as  though  such  Sub-shareholder
Account were a  Shareholder  Account other than an Omnibus  Account);  provided,
that until the Sub-transfer  Agent in respect of the ML Omnibus Account develops
the data processing  capability to conform to the foregoing  requirements,  such
Sub-transfer  Agent  shall not be  required  to conform to the  foregoing  rules
regarding Free Shares (and the Transfer Agent shall account for such Free Shares
as provided in (3) above) but shall apply the foregoing rules to each Commission
Share with respect to the Date of Original  Purchase of any Commission  Share as
though each such Date were a separate Month of Original Purchase.

          (7)  Identification  of Exchanged Shares.  When a Shareholder  Account
(other  than an  Omnibus  Account)  tenders  Shares of one Fund (the  "Redeeming
Fund")  for  redemption  where  the  proceeds  of  such  redemption  are  to  be
automatically  reinvested  in shares of  another  Fund (the  "Issuing  Fund") to
effect an exchange  (whether or not pursuant to a Free  Exchange) into Shares of
the Issuing Fund: (1) such  Shareholder  Account will be deemed to have tendered
Shares (or portions  thereof) of the Redeeming  Fund with each Month of Original
Purchase  represented  by  Shares  of  the  Redeeming  Fund  reflected  in  such
Shareholder Account immediately prior to such tender in the same proportion that
the number of Shares of the redeeming Fund with such Month of Original  Purchase
reflected in such Shareholder immediately prior to such tender bore to the total
number of Shares of the Redeeming  Fund  reflected in such  Shareholder  Account
immediately  prior to such tender,  and on that basis the tendered Shares of the
Redeeming  Fund will be identified  as  Distributor  Shares or  Post-distributor
Shares; (2) such Shareholder  Account will be deemed to have tendered Commission
Shares (or  portions  thereof)  and Free  Shares (or  portions  thereof)  of the
Redeeming Fund of each category (i.e.,  Distributor  Shares or  Post-distributor
Shares)  in the same  proportion  that the number of  Commission  Shares or Free
Shares (as the case may be) of the Redeeming Fund in such category  reflected in
such  Shareholder  Account bore to the total  number of Shares of the  Redeeming
Fund in such category reflected in such Shareholder Account immediately prior to
such tender,  (3) the Shares (or portions thereof) of the Issuing Fund issued in
connection with such exchange will be deemed to have the same Months of Original
Purchase as the Shares (or portions  thereof) of the Redeeming  Fund so tendered
and  will  be  categorized  as  Distributor  Shares and Post-distributor  Shares
accordingly,  and (4) the Shares (or portions  thereof) of each  Category of the
Issuing  Fund  issued  in  connection  with such  exchange  will be deemed to be
Commission Shares and Free Shares in the same proportion that the Shares of such
Category of the Redeeming Fund were Commission Shares and Free Shares.

          The Transfer  Agent shall require that each record owner of an Omnibus
Account  maintain  records  relating  to each  Sub-shareholder  Account  in such
Omnibus   Account   sufficient  to  apply  the  foregoing  rules  to  each  such
Sub-shareholder   Account  (as  though  such  Sub-shareholder   Account  were  a
Shareholder  Account other than an Omnibus  Account);  provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer  Agent  shall not be  required  to conform to the  foregoing  rules
relating to Free Shares (and the Sub-transfer  Agent shall account for such Free
Shares as provided in (3) above) and shall apply a first-in-first-out  procedure
(based upon the Date of Original  Purchase) to determine which Commission Shares
(or portions  thereof) of a Redeeming  Fund were redeemed in connection  with an
exchange.

          (8)  Identification  of Converted  Shares.  The Transfer Agent records
maintained for each  Shareholder  Account  (other than an Omnibus  Account) will
treat  each  Commission  Share of a Fund as though it were  redeemed  at its Net
Asset Value on the date such  Commission  Share converts into a class A share of
such Fund in  accordance  with an  applicable  Conversion  Feature  applied with
reference  to its Month of Original  Purchase  and will treat each Free Share of
such Fund with a given Month of Original  Purchase as though it were redeemed at
its Net Asset Value when it is  simultaneously  converted  to a class A share at
the time the Commission Shares of such Fund with such Month of Original Purchase
are so converted.

          The Transfer  Agent shall require that each record owner of an Omnibus
Account  maintain  records  relating  to each  Sub-shareholder  Account  in such
Omnibus   Account   sufficient  to  apply  the  foregoing  rules  to  each  such
Sub-shareholder   Account  (as  though  such  Sub-shareholder   Account  were  a
Shareholder  Account other than an Omnibus  Account) ; provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer  Agent shall apply the foregoing  rules to  Commission  Shares with
reference to the Date of Original Issue of each Commission Share (as though each
such date were a separate Month of Original  Issue) and shall not be required to
apply the  foregoing  rules to Free  Shares  (and the  Sub-transfer  Agent shall
account for such Free Shares as provided in (3) above).

          (C)  ALLOCATIONS  OF ASSET BASED SALE  CHARGES AND CDSCS AMONG  DISTRI
BUTOR SHARES AND POST-DISTRIBUTOR SHARES:

          The  Transfer  Agent shall use the  following  rules to  allocate  the
amounts of Asset Based Sales  Charges and CDSCs  payable by each Fund in respect
of Shares between Distributor Shares and Post-distributor Shares:

          (1) Receivables  Constituting CDSCs: CDSCs will be treated as relating
to Distributor  Shares or  Post-distributor  Shares  depending upon the Month of
Original  Purchase of the Commission Share the redemption of which gives rise to
the payment of a CDSC by a Shareholder Account.

          The Transfer  Agent shall cause each  Sub-transfer  Agent to apply the
foregoing rule to each  Sub-shareholder  Account based on the records maintained
by such  Sub-transfer  Agent;  provided,  that until the  Sub-transfer  Agent in
respect of the ML Omnibus  Account  develops the data  processing  capability to
conform to the foregoing  requirements,  such Sub-transfer Agent shall apply the
foregoing  rules  to  each Sub-shareholder  Account  with respect to the Date of
Original  Purchase  of any  Commission  Share as  though  each  such date were a
separate Month of Original Purchase.

          (2) Receivables Constituting Asset Based Sales Charges:

          The Asset Based Sales Charges  accruing in respect of each Shareholder
Account  (other  than an  Omnibus  Account)  shall be  allocated  to each  Share
reflected in such Shareholder Account as of the close of business on such day on
an  equal  per  share  basis.  For  example,   the  Asset  Based  Sales  Charges
attributable to Distributor Shares on any day shall be computed and allocated as
follows:

                  A  X  (B/C)

                  where:

                  A.     = Total amount of Asset Based Sales  Charge  accrued in
                         respect  of such  Shareholder  Account  (other  than an
                         Omnibus Account) on such day.

                  B.     =  Number  of  Distributor  Shares  reflected  in  such
                         Shareholder  Account (other than an Omnibus Account) on
                         the close of business on such day

                  C.     =   Total    number   of    Distributor    Shares   and
                         Post-Distributor  Shares  reflected in such Shareholder
                         Account (other than an Omnibus Account) and outstanding
                         as of the close of business on such day.

The Portion of the Asset Based Sales Charges of such Fund accruing in respect of
such Shareholder Account for such day allocated to Post-distributor  Shares will
be  obtained  using the same  formula  but  substituting  for "B" the  number of
Post-distributor  Shares,  as the case  may be,  reflected  in such  Shareholder
Account and  outstanding  on the close of business  on such day.  The  foregoing
allocation  formula may be adjusted  from time to time by notice to the Fund and
the transfer  agent for the Fund from the Seller and the Program Agent  pursuant
to Section 8.18 of the Purchase Agreement.

          The  Transfer  Agent  shall,  based on the records  maintained  by the
record  owner of such  Omnibus  Account,  allocate  the Asset Based Sales Charge
accruing   in   respect  of  each   Omnibus   Account  on  each  day  among  all
Sub-shareholder Accounts reflected in such Omnibus Account on an equal per share
basis based upon the total  number of  Distributor  Shares and  Post-distributor
Shares  reflected  in  each  such  Sub-shareholder  Account  as  of the close of
business on such day. In addition,  the Transfer Agent shall apply the foregoing
rules to each  Sub-shareholder  Account (as though it were a Shareholder Account
other than an Omnibus  Account),  based on the records  maintained by the record
owner,  to  allocate  the Asset  Based  Sales  Charge so  allocated  to any Sub-
shareholder  Account among the Distributor  Shares and  Post-distributor  Shares
reflected in each such Sub-shareholder  Account in accordance with the rules set
forth in the preceding paragraph; provided, that until the Sub-transfer Agent in
respect of the ML Omnibus Account develops the data processing capacity to apply
the rules of this  Schedule I as applicable to  Sub-shareholder  Accounts  other
than ML Omnibus  Accounts,  the  Transfer  Agent shall  allocate the Asset Based
Sales Charge accruing in respect of Shares of any Fund in the ML Omnibus Account
during any calendar  month (or portion  thereof)  among  Distributor  Shares and
Post-distributor Shares as follows:

         (a)      The  portion of such Asset  Based Sales  Charge  allocable  to
                  Distributor Shares shall be computed as follows:

                  A  X  ((B + C)/2)
                          ((D + E)/2)

                  where:

                  A      = Total  amount of Asset  Based  Sales  Charge  accrued
                         during  such  calendar  month (or  portion  thereof) in
                         respect  of  Shares  of  such  Fund  in the ML  Omnibus
                         Account

                  B      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as Distributor  Shares and outstanding as of
                         the  close  of   business   on  the  last  day  of  the
                         immediately   preceding   calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time

                  C      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as Distributor  Shares and outstanding as of
                         the close of business on the last day of such  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time

                  D      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day of the  immediately  preceding  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time.

                  E      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day  of  such  calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time.

         (b)      The  portion of such Asset  Based Sales  Charge  allocable  to
                  Post-distributor Shares shall be computed s follows:

                  A  X  ((B + C)/2)
                          ((D + E)/2)

                  where:

                  A      = Total  amount of Asset  Based  Sales  Charge  accrued
                         during  such  calendar  month (or  portion  thereof) in
                         respect  of  Shares  of  such  Fund  in the ML  Omnibus
                         Account

                  B      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as  Post-distributor  Shares and outstanding
                         as of the  close  of  business  on the  last day of the
                         immediately   preceding   calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time

                  C      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as  Post-distributor  Shares and outstanding
                         as of the  close  of  business  on the last day of such
                         calendar  month (or portion  thereof),  times Net Asset
                         Value per Share as of such time

                  D      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day of the  immediately  preceding  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time.

                  E      = Total number of Shares of such Fund in the ML Omnibus
                         Account  outstanding as of the close of business on the
                         last day of such calendar month,  times Net Asset Value
                         per Share as of such time.

         (3)  Payments on behalf of each Fund.

On the close of business on each day the Transfer  Agent shall cause  payment to
be made of the amount of the Asset Based Sales Charge and CDSCs accruing on such
day in  respect  of the  Shares  of such Fund  owned of  record  by  Shareholder
Accounts (other than Omnibus Accounts) by two separate wire transfers,  directly
from accounts of such Fund as follows:

                  1. The Asset Based Sales Charge and CDSCs  accruing in respect
                  of  Shareholder  Accounts  other  than  Omnibus  Accounts  and
                  allocable  to  Distributor   Shares  in  accordance  with  the
                  preceding  rules shall be paid to the  Distributor's  Account,
                  unless the  Distributor  otherwise  instructs  the Fund in any
                  irrevocable payment instruction; and

                  2. The Asset Based Sales Charges and CDSCs accruing in respect
                  of  Shareholder  Accounts  other  than  Omnibus  Accounts  and
                  allocable to  Post-distributor  Shares in accordance  with the
                  preceding  rules shall be paid in  accordance  with  direction
                  received from any future  distributor of Shares of the Instant
                  Fund.

          On each Omnibus CDSC Settlement Date, the Transfer Agent for each Fund
shall cause the applicable Sub-transfer Agent to cause payment to be made of the
amount of the CDSCs  accruing  during  the  period to which  such  Omnibus  CDSC
Settlement Date relates in respect of the Shares of such Fund owned of record by
each Omnibus Account by two separate wire transfers directly from the account of
such Fund maintained by such Transfer Agent, as follows:

          1. The CDSCs accruing in respect of such Omnibus Account and allocable
to Distributor  Shares in accordance  with the preceding  rules shall be paid to
the Distributor's  Account,  unless the Distributor otherwise instructs the Fund
in any irrevocable payment instruction; and

          2. The CDSCs accruing in respect of such Omnibus Account and allocable
to Post-distributor  Shares in accordance with the preceding rules shall be paid
in accordance with direction  received from any future  distributor of Shares of
the Instant Fund.

          On each Omnibus Asset Based Sales Charge  Settlement Date the Transfer
Agent for each Fund  shall  cause  payment to be made of the amount of the Asset
Based Sales Charge  accruing  for the period to which such  Omnibus  Asset Based
Sales Charge Settlement Date relates in respect of the Shares of such Fund owned
of record by each Omnibus  Account by two separate wire transfers  directly from
accounts of such Fund as follows:

          1. The Asset Based Sales  Charge  accruing in respect of such  Omnibus
Account and allocable to Distributor  Shares shall be paid to the  Distributor's
Collection Account,  unless the Distributor  otherwise instructs the Fund in any
irrevocable payment instruction; and

          2. The Asset Based Sales  Charge  accruing in respect of such  Omnibus
Account and  allocable to  Post-Distributor  Shares shall be paid in  accordance
with  direction  received from any future  distributor  of Shares of the Instant
Fund.

World Bond  Fund,  a  Massachusetts  business  trust,  ("Fund"),  and  Evergreen
Keystone  Investment  Services,  Inc., a Delaware  corporation  (the  "Principal

as follows:

         1. The Fund  hereby  appoints  the  Principal  Underwriter  a principal
underwriter  of the Class B-2 shares of  beneficial  interest  of the Fund ("B-2
Shares") as an independent  contractor upon the terms and conditions hereinafter

provided therefor in Schedule I hereto. Except as the Fund may from time to time

purchasers for the B-2 Shares and to promote  distribution of the B-2 Shares and

principal in the sale of B-2 Shares.

         3. Sales of B-2 Shares by Principal  Underwriter shall be at the public
offering  price  determined  in the  manner set forth in the  prospectus  and/or
statement  of  additional  information  of the Fund  current  at the time of the
Fund's  acceptance  of the order for B-2 Shares.  All orders shall be subject to
acceptance by the Fund and the Fund reserves the right in its sole discretion to
reject any order received. The Fund shall not be liable to anyone for failure to
accept any order.

         4. On all sales of B-2 Shares made prior to  December  11,  1996.  Fund
shall pay the Principal Underwriter  Distribution Fees (as defined in Section 14
hereof), as commissions for the sale of B-2 Shares and other Shares, which shall
be paid in conjunction with distribution fees paid to the Principal  Underwriter
by other classes of Shares of the Fund to the extent required in order to comply
with Section 14 hereof,  and shall pay over to the Principal  Underwriter  CDSCs
(as defined in Section 14 hereof) as set forth in the Fund's current  prospectus
and statement of additional  information,  and as required by Section 14 hereof.
The Principal  Underwriter shall also receive payments consisting of shareholder
service fees ("Service Fees") at the rate of .25% per annum of the average daily
net asset value of the Class B-2 Shares  outstanding prior to December 11, 1996.
The Principal  Underwriter may allow all or a part of said Distribution Fees and
CDSCs  received  by it (not  paid to  others as  hereinafter  provided)  to such
persons as Principal Underwriter may determine.

         5.  Payment to the Fund for B-2  Shares  shall be in New York or Boston
Clearing House funds received by the Principal Underwriter within three business
days after  notice of  acceptance  of the  purchase  order and the amount of the
applicable  public  offering  price  has been  given to the  purchaser.  If such
payment is not received within such period, the Fund reserves the right, without
further notice,  forthwith to cancel its acceptance of any such order.  The Fund
shall pay such issue  taxes as may be  required  by law in  connection  with the
issue of the B-2 Shares.

         6. The Principal  Underwriter shall not make in connection with the B-2
Shares any  representations  concerning the B-2 Shares except those contained in
the then current prospectus and/or statement of additional  information covering
the  Shares  and in  printed  information  approved  by the Fund as  information
supplemental to such prospectus and statement of additional information. [Copies
of the then current  prospectus and statement of additional  information and any
such  printed  supplemental  information  will be  supplied  by the  Fund to the
Principal Underwriter in reasonable quantities upon request.]

         7. The  Principal  Underwriter  agrees to comply with the Rules of Fair
Practice of the National Association of Securities Dealers,  Inc. (as defined in
the Purchase and Sale  Agreement,  dated as of December 11, 1996 (the  "Purchase
Agreement"),  between the  Principal  Underwriter,  Citibank,  N.A. and Citicorp
North America, Inc., as agent (the "Rules of Fair Practice")).

         8. The Fund appoints the Principal  Underwriter  as its agent to accept
orders for redemptions and repurchases of B-2 Shares at values and in the manner
determined in accordance with the then current  prospectus  and/or  statement of
additional information of the Fund.

         9.  The Fund  agrees  to  indemnify  and hold  harmless  the  Principal
Underwriter,  its officers and Directors  and each person,  if any, who controls

expenses (including the cost of any legal fees incurred in connection therewith)
which the Principal Underwriter, its officers, Directors or any such controlling
person may incur under the 1933 Act, under any other  statute,  at common law or
otherwise, arising out of or based upon

         a.       any untrue statement or alleged untrue statement of a material
                  fact   contained   in  the  Fund's   registration   statement,
                  prospectus or statement of additional  information  (including
                  amendments and supplements thereto) or
         
         b.       any  omission  or alleged  omission  to state a material  fact
                  required  to be stated in the Fund's  registration  statement,
                  prospectus or statement of additional information necessary to
                  make the statements therein not misleading, provided, however,
                  that  insofar  as  losses,  claims,  damages,  liabilities  or
                  expenses  arise  out of or are  based  upon  any  such  untrue
                  statement or omission or alleged untrue  statement or omission
                  made in reliance and in conformity with information  furnished
                  to the Fund by the Principal Underwriter for use in the Fund's
                  registration statement,  prospectus or statement of additional
                  information,  such  indemnification  is not applicable.  In no
                  case shall the Fund indemnify the Principal Underwriter or its
                  controlling   person  as  to  any  amounts  incurred  for  any
                  liability  arising  out of or based  upon any action for which
                  the Principal  Underwriter,  its officers and Directors or any
                  controlling  person would otherwise be subject to liability by
                  reason of willful misfeasance,  bad faith, or gross negligence
                  in the  performance of its duties or by reason of the reckless
                  disregard of its obligations and duties under this Agreement.

         10. The Principal Underwriter agrees to indemnify and hold harmless the
Fund,  its officers and Trustees and each person,  if any, who controls the Fund
within  the  meaning of Section  15 of the 1933 Act  against  any loss,  claims,
damages, liabilities and expenses (including the cost of any legal fees incurred
in connection  therewith)  which the Fund,  its officers,  Directors or any such
controlling  person may incur under the 1933 Act,  under any other  statute,  at
common law or  otherwise  arising  out of the  acquisition  of any Shares by any
person which


         (a)      may  be  based  upon  any  wrongful   act  by  the   Principal
                  Underwriter or any of its employees or representatives, or

         (b)      may be based  upon any  untrue  statement  or  alleged  untrue
                  statement  of  a  material   fact   contained  in  the  Fund's
                  registration statement,  prospectus or statement of additional
                  information (including amendments and supplements thereto), or
                  any  omission  or alleged  omission  to state a material  fact
                  required  to be  stated  therein  or  necessary  to  make  the
                  statements  therein  not  misleading,  if  such  statement  or
                  omission was made in reliance  upon  information  furnished or
                  confirmed in writing to the Fund by the Principal Underwriter.

         11.  The Fund  agrees to  execute  such  papers and to do such acts and
things  as shall  from time to time be  reasonably  requested  by the  Principal
Underwriter  for the  purpose  of  qualifying  the B-2 Shares for sale under the
so-called  "blue sky" laws of any state or for  registering B-2 Shares under the
1933 Act or the Fund under the Investment  Company Act of 1940 ("1940 Act"). The
Principal  Underwriter  shall  bear the  expenses  of  preparing,  printing  and
distributing  advertising,  sales  literature,  prospectuses,  and statements of
additional  information.  The Fund shall bear the  expense  of  registering  B-2
Shares under the 1933 Act and the Fund under the 1940 Act, qualifying B-2 Shares

printing of  prospectuses,  statements  of  additional  information  and reports
required  to be filed with the  Securities  and  Exchange  Commission  and other
authorities,   the  preparation,   printing  and  mailing  of  prospectuses  and
statements of additional  information  to holders of B-2 Shares,  and the direct

         The Principal Underwriter shall, at the request of the Fund, provide to
the Board of Trustees or Directors  (together  herein called the "Directors") of
the Fund in connection  not less than  quarterly a written report of the amounts

the Fund were made.

         The term of this Agreement  shall begin on the date hereof and,  unless

specifically  approved by a majority of the  outstanding  voting  securities  of
Class  B-2 of the  Fund or by a  majority  of the  Directors  of the  Fund and a
majority of the Directors who are not parties to this  Agreement or  "interested
persons",  as defined in the Investment Company Act of 1940 (the "1940 Act"), of
any such  party and who have no direct or  indirect  financial  interest  in the
operation  of the  Fund's  Rule  12B-2  plan  for  Class  B-2  Shares  or in any
agreements related to the plan at least annually in accordance with the 1940 Act
and the rules and regulations thereunder.

         This  Agreement may be terminated at any time,  without  payment of any
penalty,  by vote of a majority of the  Directors of the Fund,  or a majority of
such Directors who are not parties to this Agreement or "interested persons", as
defined in the 1940 Act,  of any such  party and who have no direct or  indirect
financial  interest in the operation of the Fund's Rule 12B-2 plan for Class B-2
Shares or in any agreement related to the plan or by a vote of a majority of the
outstanding  voting  securities of Class B-2 on not more than sixty days written
notice to any other party to the agreement; and shall terminate automatically in
the event of its  assignment  (as  defined  in the 1940  Act),  which  shall not
include  assignment  of the Principal  Underwriter's  (as  hereinafter  defined)
provided for hereunder and/or rights related to such Allocable Portions.

         14. The provisions of this Section 14 shall be applicable to the extent
necessary  to enable the Fund to comply with the  obligation  of the Fund to pay
the Principal  Underwriter its Allocable  Portion of  Distribution  Fees paid in
respect of Shares while the Fund is required to do so pursuant to the  Principal
Underwriting  Agreement,  of even date herewith, in respect of Class B-2 Shares,
and shall  remain in effect so long as any  payments  are required to be made by
the Fund  pursuant to the  irrevocable  payment  instruction  (as defined in the
Purchase Agreement (the "Irrevocable Payment Instruction")).

         14.1 The Fund  shall pay to the  Principal  Underwriter  the  Principal
Underwriter's   Allocable  Portion  (as  hereinafter  defined)  of  a  fee  (the
"Distribution Fee") at the rate of .75% per annum of the average daily net asset
value of the Fund  Shares  sold  prior to  December  11,  1996,  subject  to the
limitation on the maximum  aggregate amount of such fees under the Rules of Fair
Practice as applicable to such Distribution Fee on the date hereof.

         14.2 The Principal Underwriter's Allocable Portion of Distribution Fees
paid by the Fund in respect of Shares sold prior to  December  11, 1996 shall be
equal to the portion of the Asset Based Sales Charge  allocable  to  Distributor
Shares (as defined in Schedule I hereto to this  Agreement) in  accordance  with
Schedule I hereto.  The Fund agrees to cause its transfer  agent to maintain the
records and  arrange for the  payments on behalf of the Fund at the times and in
the amounts and to the accounts  required by Schedule I hereto,  as the same may
be amended from time to time.  It is  acknowledged  and agreed that by virtue of
the operation of Schedule I hereto the Principal Underwriter's Allocable Portion
of Distribution  Fees paid by the Fund in respect of Shares,  may, to the extent
provided in Schedule I hereto,  take into account  Distribution  Fees payable by
the Fund in respect of other existing  classes  and/or  sub-classes of shares of
the Fund which would be treated as "Shares"  under  Schedule I hereto.  The Fund
will limit amounts paid to any subsequent  principal  underwriters  of Shares to
the portion of the Asset Based Sales  Charge paid in respect of Shares  which is
allocable  to  Post-distributor  Shares  (as  defined  in  Schedule I hereto) in
accordance  with  Schedule  I  hereto.  The  Fund's  payments  to the  Principal
Underwriter in  consideration of its services in connection with the sale of B-2
Shares  made  prior  to  December  11,  1996  shall  be  the  Distribution  Fees
attributable to B-2 Shares sold prior to December 11, 1996 which are Distributor
Shares (as defined in Schedule I hereto) and all other amounts  constituting the
Principal  Underwriter's  Allocable  Portion of  Distribution  Fees shall be the
Distribution  Fees  related to the sale of other  Shares  which are  Distributor
Shares (as defined in Schedule I hereto).

         The Fund shall  cause its  transfer  agent and  sub-transfer  agents to
withhold  from  redemption  proceeds  payable to holders of Shares on redemption
thereof the contingent deferred sales charges payable upon redemption thereof as
set  forth  in the  then  current  prospectus  and/or  statement  of  additional
information of the Fund  ("CDSCs") and to pay over to the Principal  Underwriter
The Principal  Underwriter's  Allocable Portion of said CDSCs paid in respect of
Shares  which shall be equal to the portion  thereof  allocable  to  Distributor
Shares (as defined in Schedule I hereto) in accordance with Schedule I hereto.

         14.3 The Principal  Underwriter  shall be considered to have completely
earned the right to the payment of its Allocable Portion of the Distribution Fee
and the right to  payment  over to it of its'  Allocable  Portion of the CDSC in
respect of Shares as provided for hereby upon the completion of the sale of each
Commission  Share (as  defined  in  Schedule I hereto)  taken into  account as a
Distributor Share in computing the Principal  Underwriter's Allocable Portion in
accordance with Schedule I hereto.

         14.4  Except  as  provided  in  Section   14.5  hereof  in  respect  of
Distribution Fees only, the Fund's  obligation to pay the Principal  Underwriter
the  Distribution  Fees  and to pay  over  to the  Principal  Underwriter  CDSCs
provided for hereby shall be absolute and unconditional and shall not be subject
to dispute, offset,  counterclaim or any defense whatsoever (it being understood
that nothing in this sentence  shall be deemed a waiver by the Fund of its right
separately  to pursue any claims it may have against the  Principal  Underwriter
and  enforce  such  claims   against  any  assets   (other  than  the  Principal
Underwriter's  right to its Allocable Portion of the Distribution Fees and CDSCs
(the "Collection Rights") of the Principal Underwriter).

         14.5  Notwithstanding  anything in this Agreement to the contrary,  the
Fund  shall  pay  to  the  Principal   Underwriter  its  Allocable   Portion  of
Distribution  Fees  provided  for  hereby  notwithstanding  its  termination  as
Principal  Underwriter  for the Shares or any  termination of this Agreement and
such payment of such  Distribution  Fees, and that  obligation and the method of
computing such payment,  shall not be changed or terminated except to the extent
required by any change in applicable law,  including,  without  limitation,  the
1940 Act,  the Rules  promulgated  thereunder  by the  Securities  and  Exchange
Commission and the Rules of Fair  Practice,  in each case enacted or promulgated
after June 1, 1995, or in connection with a Complete Termination (as hereinafter
defined).  For the purposes of this Section 14.5, "Complete Termination" means a
termination of the Fund's Rule 12B-2 plan for B-2 Shares involving the cessation
of  payments  of the  Distribution  Fees,  and  the  cessation  of  payments  of
distribution  fees pursuant to every other Rule 12B-2 plan of the Fund for every
existing or future  B-Class-of-Shares  (as  hereinafter  defined) and the Fund's
discontinuance of the offering of every existing or future  B-Class-of-  Shares,
which  conditions  shall be deemed  satisfied  when they are first complied with
hereafter and so long  thereafter as they are complied with prior to the earlier
of (i) the date upon which all of the B-2 Shares  which are  Distributor  Shares
pursuant to Schedule I hereto shall have been redeemed or converted or (ii) June
1, 2005.  For purposes of this Section 14.5, the term B-Class-  of-Shares  means
each of the B-2 Class of Shares of the Fund, the B-2 Class of Shares of the Fund
and each  other  class of shares of the Fund  hereafter  issued  which  would be
treated as Shares  under  Schedule I hereto or which has  substantially  similar
economic characteristics to the B-2 or B-2 Classes of Shares taking into account
the  total  sales  charge,  CDSC or other  similar  charges  borne  directly  or
indirectly by the holder of the shares of such class. The parties agree that the
existing  C Class of  Shares  of the Fund  does not have  substantially  similar
economic characteristics to the B-2 or B-2 Classes of Shares taking into account
the  total  sales  charge,  CDSC or other  similar  charges  borne  directly  or
indirectly by the holder of such shares.  For purposes of clarity the parties to
this agreement  hereby state that they intend that a new installment  load class
of shares which may be  authorized  by amendments to Rule 6(c)-10 under the 1940
Act  will  be  considered  to  be  a   B-Class-of-Shares   if  it  has  economic
characteristics  substantially  similar to the economic  characteristics  of the
existing B-2 or B-2 Classes of Shares taking into account the total sale charge,
CDSC or other similar charges borne directly or indirectly by the holder of such
shares and will not be considered to be a  B-Class-of-Shares  if it has economic
characteristics  substantially  similar to the economic  characteristics  of the
existing  C Class of shares of the Fund  taking  into  account  the total  sales
charge, CDSC or other similar charges borne directly or indirectly by the holder
of such shares.

         14.6 The  Principal  Underwriter  may assign any part of its  Allocable
Portions  and  obligations  of the Fund related  thereto (but not the  Principal
Underwriter's  obligations  to the Fund  provided for in this  Agreement) to any
person (an "Assignee") and any such assignment shall be effective as to the Fund
upon written  notice to the Fund by the  Principal  Underwriter.  In  connection
therewith  the Fund shall pay all or any  amounts  in  respect of its  Allocable
Portions  directly  to the  Assignee  thereof  as  directed  in a writing by the
Principal Underwriter in the Irrevocable Payment Instruction, as the same may be
amended  from time to time with the  consent of the Fund,  and the Fund shall be
without liability to any person if it pays such amounts when and as so directed,
except for  underpayments of amounts actually due, without any amount payable as
consequential  or other damages due to such  underpayment  and without  interest
except to the  extent  that  delay in  payment  of  Distribution  Fees and CDSCs
results in an increase in the maximum Sales Charge  allowable under the Rules of
Fair  Practice,  which  increases  daily at a rate of prime plus one percent per
annum.

         14.7 The Fund will not, to the extent it may  otherwise be empowered to
do so,  change or waive any CDSC with respect to B-2 Shares,  except as provided
in the Fund's  prospectus  or statement of  additional  information  without the
Principal  Underwriter's or Assignee's consent,  as applicable.  Notwithstanding
anything to the contrary in this Agreement or any  termination of this Agreement
or the  Principal  Underwriter  as principal  underwriter  for the Shares of the
Fund,  the  Principal  Underwriter  shall be entitled  to be paid its  Allocable
Portion of the CDSCs whether or not the Fund's Rule 12B-2 plan for B-2 Shares is
terminated and whether or not any such termination is a Complete Termination, as
defined above.

         15. This  Agreement  shall be construed in accordance  with the laws of
The Commonwealth of Massachusetts. All sales hereunder are to be made, and title
to the Shares shall pass, in Boston, Massachusetts.

         16. The Fund is a  Massachusetts  business  trust  established  under a
Declaration of Trust, as it may be amended from time to time. The obligations of
the Fund are not personally  binding upon, nor shall recourse be had against the
private property of any of the Trustees,  shareholders,  officers,  employees or
agents of the Fund, but only the property of the Fund shall be bound.

          (1) Shareholder  Accounts and Sub-shareholder  Accounts.  The Transfer

record  owner of Shares of each  Fund.  Each  Shareholder  Account  (other  than
Omnibus  Accounts)  will  represent a record  owner of Shares of such Fund,  the
records of which will be kept in accordance with this Schedule I. In the case of
an Omnibus  Account,  the Transfer  Agent shall require that the record owner of
the Omnibus Account  maintain a separate account (a  "Sub-shareholder  Account")
for each record owner of Shares which are reflected in the Omnibus Account,  the
records  of which will be kept in  accordance  with this  Schedule  I. Each such
Shareholder Account and Sub-shareholder Account shall relate solely to Shares of
such Fund and shall not relate to any other class of shares of such Fund.

          (2) Commission  Shares.  For each  Shareholder  Account (other than an
Omnibus  Account),  the  Transfer  Agent shall  maintain  daily  records of each
Commission Share of such Fund which records shall identify each Commission Share
of such Fund  reflected  in such  Shareholder  Account by the Month of  Original
Purchase of such Commission Share.

          For each Omnibus  Account,  the Transfer  Agent shall require that the
Sub-  transfer  Agent  in  respect  thereof   maintain  daily  records  of  such
Sub-shareholder  Account which records shall identify each  Commission  Share of
such Fund  reflected in such Sub-  shareholder  Account by the Month of Original
Purchase;  provided,  that  until the Sub-  transfer  Agent in respect of the ML
Omnibus  Account  develops  the data  processing  capability  to  conform to the
foregoing requirements,  such Sub-transfer Agent shall maintain daily records of
Sub-shareholder  Accounts  which  identify  each  Commission  Share of such Fund
reflected in such Sub-shareholder Account by the Date of Original Purchase. Each
such  Commission  Share shall be identified  as either a Distributor  Share or a
Post-distributor  Share  based  upon the  Month  of  Original  Purchase  of such
Commission  Share (or in the case of a  Sub-shareholder  Account  within  the ML
Omnibus Account, based upon the Date of Original Purchase).

          (3) Free Shares.  The Transfer  Agent shall  maintain daily records of
each Shareholder  Account (other than an Omnibus Account) in respect of any Fund
so as to identify each Free Share  (including each Special Free Share) reflected
in such  Shareholder  Account  by the Month of  Original  Purchase  of such Free
Share.  In addition,  the  Transfer  Agent shall  require that each  Shareholder
Account  (other  than an  Omnibus  Account)  have in effect  separate  elections
relating to  reinvestment of Capital Gain Dividends and relating to reinvestment
of Other Dividends in respect of any Fund. Either such Shareholder Account shall
have elected to reinvest all Capital Gain Dividends or such Shareholder  Account
shall have elected to have all Capital Gain  Dividends  distributed.  Similarly,
either  such  Shareholder  Account  shall  have  elected to  reinvest  all Other
Dividends  or such  Shareholder  Account  shall  have  elected to have all Other
Dividends distributed.

          The  Transfer  Agent  shall  require  that the  Sub-transfer  Agent in
respect of each Omnibus Account maintain daily records for each  Sub-shareholder
Account in the manner  described  in the  immediately  preceding  paragraph  for
Shareholder  Accounts (other than Omnibus  Accounts);  provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer   Agent  shall  not  be  obligated  to  conform  to  the  foregoing
requirements.  Each  Sub-shareholder  Account shall also have in effect Dividend
reinvestment elections as described in the immediately preceding paragraph.

          The  Transfer  Agent  and each  Sub-transfer  Agent in  respect  of an
Omnibus Account shall identify each Free Share as either a Distributor  Share or
a Post-distributor  Share based upon the Month of Original Purchase of such Free
Share; provided,  that until the Sub-transfer Agent in respect of the ML Omnibus
Account  develops the data  processing  capability  to conform to the  foregoing
requirements,  the  Transfer  Agent shall  require  such  Sub-transfer  Agent to
identify  each  Free  Share  of a given  Fund  in the ML  Omnibus  Account  as a
Distributor Share, or Post-distributor Share, as follows:

         (a)      Free  Shares  of  such  Fund  which  are  outstanding  on  the

                           as of the  close of  business  on the last day of the
                           immediately preceding calendar month.

                  C        = Total  number of Free Shares of such Fund in the ML
                           Omnibus  Account and  outstanding  as of the close of
                           business on the last day of the immediately preceding
                           calendar month.

          (4) Appreciation  Amount and Cost  Accumulation  Amount.  The Transfer
Agent shall  maintain on a daily  basis in respect of each  Shareholder  Account
(other than Omnibus Accounts) a Cost Accumulation  Amount representing the total
of the  Original  Purchase  Amounts  paid by such  Shareholder  Account  for all
Commission  Shares  reflected  in such  Shareholder  Account  as of the close of
business on each day. In addition,  the Transfer Agent shall maintain on a daily
basis in respect of each  Shareholder  Account  (other  than  Omnibus  Accounts)
sufficient  records  to enable it to  compute,  as of the date of any  actual or
deemed  redemption  or Free  Exchange of a  Commission  Share  reflected in such
Shareholder  Account an amount (such amount an  "Appreciation  Amount") equal to
the  excess,  if any, of the Net Asset Value as of the close of business on such
day of the Commission  Shares  reflected in such  Shareholder  Account minus the
Cost  Accumulation  Amount as of the close of business on such day. In the event
that a Commission Share (or portion thereof) reflected in a Shareholder  Account
is redeemed or under these rules is deemed to have been  redeemed  (whether in a
Free  Exchange  or  otherwise),  the  Appreciation  Amount for such  Shareholder
Account shall be reduced,  to the extent thereof,  by the Net Asset Value of the
Commission  Share (or portion thereof)  redeemed,  and if the Net Asset Value of
the Commission  Share (or portion  thereof) being redeemed equals or exceeds the
Appreciation  Amount, the Cost Accumulation Amount will be reduced to the extent
thereof, by such excess. If the Appreciation Amount for such Shareholder Account
immediately  prior to any redemption of a Commission  Share (or portion thereof)
is equal to or greater  than the Net Asset  Value of such  Commission  Share (or
portion  thereof) deemed to have been tendered for redemption,  no CDSCs will be
payable in respect of such Commission Share (or portion thereof).

          The  Transfer  Agent  shall  require  that the  Sub-transfer  Agent in
respect of each  Omnibus  Account  maintain  on a daily basis in respect of each
Sub-shareholder  Account  reflected in such Omnibus Account a Cost  Accumulation
Amount and  sufficient  records to enable it to  compute,  as of the date of any
actual or deemed  redemption or Free Exchange of a Commission Share reflected in
such  Sub-shareholder  Account an  Appreciation  Amount in  accordance  with the
preceding paragraph and to apply the same to determine whether a CDSC is payable
(as though such Sub-shareholder Account were a Shareholder Account other than an
Omnibus Account;  provided, that until the Sub- transfer Agent in respect of the
ML Omnibus  Account  develops the data  processing  capability to conform to the
foregoing  requirements,   such  Sub-transfer  Agent  shall  maintain  for  each
Sub-shareholder  Account a  separate  Cost  Accumulation  Amount  and a separate
Appreciation  Amount for each Date of Original  Purchase of any Commission Share
which shall be applied as set forth in the  preceding  paragraph as if each Date
of Original Purchase were a separate Month of Original Purchase.

          (5) NASD Cap. On the date the distribution fees paid in respect of any
class of  Shares  equals  the  maximum  amount  thereon  under the Rules of Fair
Practice, in respect of such class, all outstanding Shares of such class of such
Fund shall be  converted  into Class A shares of such Fund and will be deemed to
have been redeemed for their Net Asset Value for purposes of this Schedule I.

          (6) Identification of Redeemed Shares. If a Shareholder Account (other
than an Omnibus Account) tenders a Share of a Fund for redemption (other than in
connection  with an  exchange  of such Share for a Share of  another  Fund or in
connection with the conversion of such Share pursuant to a Conversion  Feature),
such  tendered  Share  will be deemed  to be a Free  Share if there are any Free
Shares reflected in such Shareholder  Account  immediately prior to such tender.
If there is more  than one Free  Share  reflected  in such  Shareholder  Account
immediately  prior to such tender,  such tendered Share will be deemed to be the
Free Share with the earliest  Month of Original  Purchase.  If there are no Free
Shares reflected in such Shareholder  Account  immediately prior to such tender,
such tendered Share will be deemed to be the Commission  Share with the earliest
Month of Original Purchase reflected in such Shareholder Account.

          If a Sub-shareholder Account reflected in an Omnibus Account tenders a
Share for  redemption  (other than in connection  with an Exchange of such Share
for a Share of another Fund or in connection  with the  conversion of such Share
pursuant to a Conversion  Feature),  the Transfer  Agent shall  require that the
record  owner of each  Omnibus  Account  supply the  Transfer  Agent  sufficient
records  to  enable  the  Transfer  Agent to apply  the  rules of the  preceding
paragraph  to such  Sub-shareholder  Account  (as  though  such  Sub-shareholder
Account were a  Shareholder  Account other than an Omnibus  Account);  provided,
that until the Sub-transfer  Agent in respect of the ML Omnibus Account develops
the data processing  capability to conform to the foregoing  requirements,  such
Sub-transfer  Agent  shall not be  required  to conform to the  foregoing  rules
regarding Free Shares (and the Transfer Agent shall account for such Free Shares
as provided in (3) above) but shall apply the foregoing rules to each Commission
Share with respect to the Date of Original  Purchase of any Commission  Share as
though each such Date were a separate Month of Original Purchase.

          (7)  Identification  of Exchanged Shares.  When a Shareholder  Account
(other  than an  Omnibus  Account)  tenders  Shares of one Fund (the  "Redeeming
Fund")  for  redemption  where  the  proceeds  of  such  redemption  are  to  be
automatically  reinvested  in shares of  another  Fund (the  "Issuing  Fund") to
effect an exchange  (whether or not pursuant to a Free  Exchange) into Shares of
the Issuing Fund: (1) such  Shareholder  Account will be deemed to have tendered
Shares (or portions  thereof) of the Redeeming  Fund with each Month of Original
Purchase  represented  by  Shares  of  the  Redeeming  Fund  reflected  in  such
Shareholder Account immediately prior to such tender in the same proportion that
the number of Shares of the redeeming Fund with such Month of Original  Purchase
reflected in such Shareholder immediately prior to such tender bore to the total
number of Shares of the Redeeming  Fund  reflected in such  Shareholder  Account
immediately  prior to such tender,  and on that basis the tendered Shares of the
Redeeming  Fund will be identified  as  Distributor  Shares or  Post-distributor
Shares; (2) such Shareholder  Account will be deemed to have tendered Commission
Shares (or  portions  thereof)  and Free  Shares (or  portions  thereof)  of the
Redeeming Fund of each category (i.e.,  Distributor  Shares or  Post-distributor
Shares)  in the same  proportion  that the number of  Commission  Shares or Free
Shares (as the case may be) of the Redeeming Fund in such category  reflected in
such  Shareholder  Account bore to the total  number of Shares of the  Redeeming
Fund in such category reflected in such Shareholder Account immediately prior to
such tender,  (3) the Shares (or portions thereof) of the Issuing Fund issued in
connection with such exchange will be deemed to have the same Months of Original
Purchase as the Shares (or portions  thereof) of the Redeeming  Fund so tendered
and will be  categorized  as  Distributor  Shares and Post-  distributor  Shares
accordingly,  and (4) the Shares (or portions  thereof) of each  Category of the
Issuing  Fund  issued  in  connection  with such  exchange  will be deemed to be
Commission Shares and Free Shares in the same proportion that the Shares of such
Category of the Redeeming Fund were Commission Shares and Free Shares.

          The Transfer  Agent shall require that each record owner of an Omnibus
Account  maintain  records  relating  to each  Sub-shareholder  Account  in such
Omnibus   Account   sufficient  to  apply  the  foregoing  rules  to  each  such
Sub-shareholder   Account  (as  though  such  Sub-shareholder   Account  were  a
Shareholder  Account other than an Omnibus  Account);  provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer  Agent  shall not be  required  to conform to the  foregoing  rules
relating to Free Shares (and the Sub-transfer  Agent shall account for such Free
Shares as provided in (3) above) and shall apply a first-in-first-out  procedure
(based upon the Date of Original  Purchase) to determine which Commission Shares
(or portions  thereof) of a Redeeming  Fund were redeemed in connection  with an
exchange.

          (8)  Identification  of Converted  Shares.  The Transfer Agent records
maintained for each  Shareholder  Account  (other than an Omnibus  Account) will
treat  each  Commission  Share of a Fund as though it were  redeemed  at its Net
Asset Value on the date such  Commission  Share converts into a class A share of
such Fund in  accordance  with an  applicable  Conversion  Feature  applied with
reference  to its Month of Original  Purchase  and will treat each Free Share of
such Fund with a given Month of Original  Purchase as though it were redeemed at
its Net Asset Value when it is  simultaneously  converted  to a class A share at
the time the Commission Shares of such Fund with such Month of Original Purchase
are so converted.

          The Transfer  Agent shall require that each record owner of an Omnibus
Account  maintain  records  relating  to each  Sub-shareholder  Account  in such
Omnibus   Account   sufficient  to  apply  the  foregoing  rules  to  each  such
Sub-shareholder   Account  (as  though  such  Sub-shareholder   Account  were  a
Shareholder  Account other than an Omnibus  Account) ; provided,  that until the
Sub-transfer  Agent in  respect  of the ML  Omnibus  Account  develops  the data
processing   capability   to  conform  to  the  foregoing   requirements,   such
Sub-transfer  Agent shall apply the foregoing  rules to  Commission  Shares with
reference to the Date of Original Issue of each Commission Share (as though each
such date were a separate Month of Original  Issue) and shall not be required to
apply the  foregoing  rules to Free  Shares  (and the  Sub-transfer  Agent shall
account for such Free Shares as provided in (3) above).

          (C)  ALLOCATIONS  OF ASSET BASED SALE  CHARGES AND CDSCS AMONG  DISTRI
BUTOR SHARES AND POST-DISTRIBUTOR SHARES:

          The  Transfer  Agent shall use the  following  rules to  allocate  the
amounts of Asset Based Sales  Charges and CDSCs  payable by each Fund in respect
of Shares between Distributor Shares and Post-distributor Shares:

          (1) Receivables  Constituting CDSCs: CDSCs will be treated as relating
to Distributor  Shares or  Post-distributor  Shares  depending upon the Month of
Original  Purchase of the Commission Share the redemption of which gives rise to
the payment of a CDSC by a Shareholder Account.

          The Transfer  Agent shall cause each  Sub-transfer  Agent to apply the
foregoing rule to each  Sub-shareholder  Account based on the records maintained
by such  Sub-transfer  Agent;  provided,  that until the  Sub-transfer  Agent in
respect of the ML Omnibus  Account  develops the data  processing  capability to
conform to the foregoing  requirements,  such Sub-transfer Agent shall apply the
foregoing  rules to each Sub-  shareholder  Account  with respect to the Date of
Original  Purchase  of any  Commission  Share as  though  each  such date were a
separate Month of Original Purchase.

          (2) Receivables Constituting Asset Based Sales Charges:

          The Asset Based Sales Charges  accruing in respect of each Shareholder
Account  (other  than an  Omnibus  Account)  shall be  allocated  to each  Share
reflected in such Shareholder Account as of the close of business on such day on
an  equal  per  share  basis.  For  example,   the  Asset  Based  Sales  Charges
attributable to Distributor Shares on any day shall be computed and allocated as
follows:

                  A  X  (B/C)

                  where:

                  A.     = Total amount of Asset Based Sales  Charge  accrued in
                         respect  of such  Shareholder  Account  (other  than an
                         Omnibus Account) on such day.

                  B.     =  Number  of  Distributor  Shares  reflected  in  such
                         Shareholder  Account (other than an Omnibus Account) on
                         the close of business on such day

                  C.     =   Total    number   of    Distributor    Shares   and
                         Post-Distributor  Shares  reflected in such Shareholder
                         Account (other than an Omnibus Account) and outstanding
                         as of the close of business on such day.

The Portion of the Asset Based Sales Charges of such Fund accruing in respect of
such Shareholder Account for such day allocated to Post-distributor  Shares will
be  obtained  using the same  formula  but  substituting  for "B" the  number of
Post-distributor  Shares,  as the case  may be,  reflected  in such  Shareholder
Account and  outstanding  on the close of business  on such day.  The  foregoing
allocation  formula may be adjusted  from time to time by notice to the Fund and
the transfer  agent for the Fund from the Seller and the Program Agent  pursuant
to Section 8.18 of the Purchase Agreement.

          The  Transfer  Agent  shall,  based on the records  maintained  by the
record  owner of such  Omnibus  Account,  allocate  the Asset Based Sales Charge
accruing   in   respect  of  each   Omnibus   Account  on  each  day  among  all
Sub-shareholder Accounts reflected in such Omnibus Account on an equal per share
basis based upon the total  number of  Distributor  Shares and  Post-distributor
Shares  reflected  in each  such  Sub-  shareholder  Account  as of the close of
business on such day. In addition,  the Transfer Agent shall apply the foregoing
rules to each  Sub-shareholder  Account (as though it were a Shareholder Account
other than an Omnibus  Account),  based on the records  maintained by the record
owner,  to  allocate  the Asset  Based  Sales  Charge so  allocated  to any Sub-
shareholder  Account among the Distributor  Shares and  Post-distributor  Shares
reflected in each such Sub-shareholder  Account in accordance with the rules set
forth in the preceding paragraph; provided, that until the Sub-transfer Agent in
respect of the ML Omnibus Account develops the data processing capacity to apply
the rules of this  Schedule I as applicable to  Sub-shareholder  Accounts  other
than ML Omnibus  Accounts,  the  Transfer  Agent shall  allocate the Asset Based
Sales Charge accruing in respect of Shares of any Fund in the ML Omnibus Account
during any calendar  month (or portion  thereof)  among  Distributor  Shares and
Post-distributor Shares as follows:

         (a)      The  portion of such Asset  Based Sales  Charge  allocable  to
                  Distributor Shares shall be computed as follows:

                  A  X  ((B + C)/2)
                          ((D + E)/2)

                  where:

                  A      = Total  amount of Asset  Based  Sales  Charge  accrued
                         during  such  calendar  month (or  portion  thereof) in
                         respect  of  Shares  of  such  Fund  in the ML  Omnibus
                         Account

                  B      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as Distributor  Shares and outstanding as of
                         the  close  of   business   on  the  last  day  of  the
                         immediately   preceding   calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time

                  C      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as Distributor  Shares and outstanding as of
                         the close of business on the last day of such  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time

                  D      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day of the  immediately  preceding  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time.

                  E      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day  of  such  calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time.

         (b)      The  portion of such Asset  Based Sales  Charge  allocable  to
                  Post-distributor Shares shall be computed s follows:

                  A  X  ((B + C)/2)
                          ((D + E)/2)

                  where:

                  A      = Total  amount of Asset  Based  Sales  Charge  accrued
                         during  such  calendar  month (or  portion  thereof) in
                         respect  of  Shares  of  such  Fund  in the ML  Omnibus
                         Account

                  B      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as  Post-distributor  Shares and outstanding
                         as of the  close  of  business  on the  last day of the
                         immediately   preceding   calendar  month  (or  portion
                         thereof),  times Net  Asset  Value per Share as of such
                         time

                  C      = Shares of such  Fund in the ML  Omnibus  Account  and
                         identified as  Post-distributor  Shares and outstanding
                         as of the  close  of  business  on the last day of such
                         calendar  month (or portion  thereof),  times Net Asset
                         Value per Share as of such time

                  D      = Total number of Shares of such Fund in the ML Omnibus
                         Account and  outstanding as of the close of business on
                         the  last  day of the  immediately  preceding  calendar
                         month (or portion  thereof),  times Net Asset Value per
                         Share as of such time.

                  E      = Total number of Shares of such Fund in the ML Omnibus
                         Account  outstanding as of the close of business on the

                         per Share as of such time.

         (3)  Payments on behalf of each Fund.

On the close of business on each day the Transfer  Agent shall cause  payment to
be made of the amount of the Asset Based Sales Charge and CDSCs accruing on such
day in  respect  of the  Shares  of such Fund  owned of  record  by  Shareholder
Accounts (other than Omnibus Accounts) by two separate wire transfers,  directly
from accounts of such Fund as follows:

                  1. The Asset Based Sales Charge and CDSCs  accruing in respect
                  of  Shareholder  Accounts  other  than  Omnibus  Accounts  and
                  allocable  to  Distributor   Shares  in  accordance  with  the
                  preceding  rules shall be paid to the  Distributor's  Account,
                  unless the  Distributor  otherwise  instructs  the Fund in any
                  irrevocable payment instruction; and

                  2. The Asset Based Sales Charges and CDSCs accruing in respect
                  of  Shareholder  Accounts  other  than  Omnibus  Accounts  and
                  allocable to  Post-distributor  Shares in accordance  with the
                  preceding  rules shall be paid in  accordance  with  direction
                  received from any future  distributor of Shares of the Instant
                  Fund.

          On each Omnibus CDSC Settlement Date, the Transfer Agent for each Fund
shall cause the applicable Sub-transfer Agent to cause payment to be made of the
amount of the CDSCs  accruing  during  the  period to which  such  Omnibus  CDSC
Settlement Date relates in respect of the Shares of such Fund owned of record by
each Omnibus Account by two separate wire transfers directly from the account of
such Fund maintained by such Transfer Agent, as follows:

          1. The CDSCs accruing in respect of such Omnibus Account and allocable
to Distributor  Shares in accordance  with the preceding  rules shall be paid to
the Distributor's  Account,  unless the Distributor otherwise instructs the Fund
in any irrevocable payment instruction; and

          2. The CDSCs accruing in respect of such Omnibus Account and allocable
to Post-distributor  Shares in accordance with the preceding rules shall be paid
in accordance with direction  received from any future  distributor of Shares of
the Instant Fund.

          On each Omnibus Asset Based Sales Charge  Settlement Date the Transfer
Agent for each Fund  shall  cause  payment to be made of the amount of the Asset
Based Sales Charge  accruing  for the period to which such  Omnibus  Asset Based
Sales Charge Settlement Date relates in respect of the Shares of such Fund owned
of record by each Omnibus  Account by two separate wire transfers  directly from
accounts of such Fund as follows:

          1. The Asset Based Sales  Charge  accruing in respect of such  Omnibus
Account and allocable to Distributor  Shares shall be paid to the  Distributor's
Collection Account,  unless the Distributor  otherwise instructs the Fund in any
irrevocable payment instruction; and

          2. The Asset Based Sales  Charge  accruing in respect of such  Omnibus
Account and  allocable to  Post-Distributor  Shares shall be paid in  accordance
with  direction  received from any future  distributor  of Shares of the Instant
Fund.
