    Colonial Investment Grade Bond Fund is a diversified, closed-end management
investment company that seeks, as its primary investment objective, to provide
high current income. The Fund's secondary investment objective is to seek total
return. Under normal circumstances, the Fund will invest at least 80% of its
assets in investment grade debt securities (debt securities that are rated at
least Baa/BBB or their equivalent by a rating agency or are determined by
Colonial Management Associates, Inc., the Fund's investment advisor (the
"Advisor"), to be of comparable quality). The Fund generally expects to maintain
an intermediate to long duration (approximately 3-7 years). The Fund may
leverage its portfolio, through certain derivative instruments, or otherwise,
when the Advisor believes it would benefit the Fund. The use of leverage
involves certain special risks. (See "Summary -- Special Risk
Considerations -- Leverage Risk.") No assurance can be given that the Fund's
investment objectives will be achieved. An investment in the Fund is not
appropriate for all investors.

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

(1) The shares are continuously offered on a best efforts basis at a price equal
    to the net asset value per share next determined after receipt of a properly
    completed purchase order, plus in the case of Class A shares, an initial
    sales charge if any. It is expected that the initial net asset value per
    share of the Fund will be $12.00. The minimum initial investment is $2,500,
    and the minimum subsequent investment is $50.



(2) The maximum initial sales charge on Class A shares is 3.5%. Class B and C
    shares are not subject to an initial sales charge but are subject to an
    early withdrawal charge. Class A, B and C shares are subject to a
    distribution fee and a service fee. The Distributor will pay all sales
    commissions to authorized dealers from its own assets.



(3) Assumes the sale of all shares registered hereby, and the exclusion of
    approximately $271,020 of organizational and initial offering expenses
    payable by the Advisor.



    PERIODIC TENDER OFFERS.  To provide liquidity to shareholders, the Fund will
make quarterly repurchase offers, generally for 5% to 25% of its outstanding
shares. The time between the notification to shareholders of a tender offer and
the deadline for shareholders to provide their repurchase requests (the
"Repurchase Request Deadline") may vary from three to six weeks. The repurchase
of the shares will be the net asset value as of the close of regular trading on
the New York Stock Exchange ("NYSE") on the date on which the repurchase price
is determined (the "Repurchase Pricing Date"). The Repurchase Pricing Date
normally will be the same date as the Repurchase Request Deadline. Repurchase
proceeds generally will be paid to shareholders in cash within seven days after
each Repurchase Pricing Date. It is anticipated that the initial Repurchase
Request Deadline will be on July 17, 2000. (See "Periodic Tender Offers.")



    NOT EXCHANGE LISTED.  The Fund does not intend to list the shares on any
national securities exchange. Shares of the Fund have no history of public
trading and there is not expected to be any secondary trading market in the
shares. An investment in the shares should be considered illiquid. The shares of
closed-end investment companies often trade at a discount from their net asset
values and, in the unlikely event that a secondary market for the shares were to
develop, the Fund's shares likewise may trade at a discount from net asset
value. (See "Special Risk Considerations.")

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


    This prospectus applies to the offering of shares of beneficial interest of
the Fund, which may be continuously issued and sold from time to time by the
Fund through the Distributor, as distributor and principal underwriter, and
through your financial advisor. (See "How to Buy Shares.")



    The Fund's Class A shares are subject to a front-end sales charge and to a
distribution fee and other expenses. The Fund's Class B shares will not be
subject to a front-end sales charge, but will be subject to a declining early
withdrawal charge (EWC) over a six-year period and a distribution fee, as well
as other expenses. Class B shares will convert automatically to Class A shares
eight years from the date of purchase. The Fund's Class C shares will not be
subject to a front-end sales charge, but will be subject to an EWC of 1% during
the first year a shareholder owns Class C shares and a distribution fee, as well
as other expenses. The Fund may add additional classes of shares in the future.

                               PROSPECTUS SUMMARY

     This summary highlights selected information from this Prospectus. It may
not contain all of the information that is important to you. You should read
this entire Prospectus carefully, including the risk factors. This summary is
qualified in its entirety by reference to the detailed information included in
this Prospectus and the Statement of Additional Information.


THE FUND......................   Colonial Investment Grade Bond Fund is a newly
                                 organized, diversified, closed-end management
                                 investment company. See "The Fund." The Fund
                                 was organized as a Massachusetts business trust
                                 on November 16, 1999 and has registered under
                                 the Investment Company Act of 1940.



                                 The Fund intends to offer its shares
                                 continuously through the Distributor, as
                                 principal underwriter, and through financial
                                 advisors at a price equal to the next
                                 determined net asset value per share plus, in
                                 the case of class A shares, the applicable
                                 sales charge per share. The minimum initial
                                 investment is $2,500 and the minimum subsequent
                                 investment is $50. The Fund reserves the right
                                 to change the investment minimums and to refuse
                                 a purchase order for any reason.



CLASSES OF SHARES.............   The Fund offers three classes of shares in this
                                 prospectus, with each class having its own
                                 sales charge and expense structure. Each class
                                 has distinct advantages and disadvantages for
                                 different investors. (See "Multiple Pricing
                                 System.")



INVESTMENT OBJECTIVES.........   The Fund's primary investment objective is to
                                 provide high current income. The Fund's
                                 secondary objective is to seek total return.



INVESTMENT STRATEGIES.........   The Fund seeks to achieve its investment goals
                                 by investing in:



                                      - Debt securities issued by the U.S.
                                        government or U.S. corporations
                                        (including mortgage- and other
                                        asset-backed securities); and


                                      - Debt securities issued by foreign
                                        governments or corporations.


                                 The Fund has wide flexibility to vary its
                                 allocation of investments among debt securities
                                 at any given time based on the Advisor's
                                 estimate of the expected performance and risk
                                 of each type of investment.



                                 The Fund may also invest to a lesser extent in
                                 common and preferred stocks to pursue its goal
                                 of total return.



                                 The Fund may, to the extent permitted by the
                                 Investment Company Act of 1940, "leverage" its
                                 portfolio by investing borrowed money when the
                                 Advisor believes it would benefit the Fund. The
                                 Fund has no current intention to leverage its
                                 portfolio through bank borrowings. The Fund may
                                 also, and currently expects to, leverage its
                                 portfolio through the use of reverse repurchase
                                 agreements, short sales and certain derivative
                                 instruments.

                                 Although the Fund normally invests at least 80%
                                 of its assets in investment grade debt
                                 securities, it may invest the remainder of its
                                 assets in lower-rated debt securities.
                                 Lower-rated securities are:



                                      - rated below BBB by Standard & Poor's
                                        Rating Services, a division of The
                                        McGraw-Hill Companies, Inc. ("Standard &
                                        Poor's");



                                      - rated below BBB by Moody's Investor
                                        Services, Inc.;



                                      - assigned a comparable rating by another
                                        nationally recognized rating service; or


                                      - unrated and believed by the Advisor to
                                        be comparable in quality to a
                                        lower-rated debt security.


                                 The Fund may invest up to 35% of its assets in
                                 securities issued or guaranteed by foreign
                                 governments or foreign companies, including
                                 securities issued in emerging market countries.



                                 The Fund has adopted certain fundamental
                                 investment restrictions set forth in the
                                 Statement of Additional Information which may
                                 not be changed without approval by the Fund's
                                 shareholders. Except for such restrictions and
                                 as otherwise specified, approval by the Fund's
                                 shareholders is not required to modify or
                                 change the Fund's goals or investment
                                 strategies.



SPECIAL RISK CONSIDERATIONS...   The primary risks of investing in the Fund are
                                 described below. There are many circumstances
                                 (that are not described here) which could cause
                                 you to lose money by investing in the Fund or
                                 prevent the Fund from achieving its goals.



                                 No operating history.  The Fund is a newly
                                 organized, closed-end investment company with
                                 no history of operations.



                                 Interest rate risk is the risk of a change in
                                 the price of a bond when interest rates change.
                                 In general, if interest rates rise, bond prices
                                 fall and if interest rates fall, bond prices
                                 rise. Changes in the values of bonds usually
                                 will not affect the amount of income the Fund
                                 receives from them but will affect the value of
                                 the Fund's shares. Interest rate risk is
                                 generally greater for bonds with longer
                                 maturities.



                                 Market risk is the risk that the price of a
                                 security held by the Fund will fall due to
                                 changing economic, political or market
                                 conditions, or due to the financial condition
                                 of the issuer of the security. Because stocks
                                 purchased by the Fund pay dividends only after
                                 payments are made to bond holders, the value of
                                 stocks usually will react more strongly than
                                 bonds to actual or perceived changes in the
                                 issuers' financial condition.



                                 Leverage risk.  The use of leverage through the
                                 purchase of certain derivative instruments or
                                 the use of reverse repurchase agreement or
                                 short sale transactions will create an
                                 opportunity for increased net income, but will
                                 also create special risks. The Fund intends to
                                 use leverage to provide the holders of the
                                 shares with a potentially higher return, but
                                 its leveraging strategy may


                                        2

                                 not be successful. If the income from the
                                 securities purchased with leverage proceeds is
                                 not sufficient to cover the cost of leverage,
                                 the Fund's return will be lower than if
                                 leverage had not been used. Leverage creates
                                 risks for holders of the shares, including the
                                 likelihood of greater volatility of the net
                                 asset value and market price of the shares.



                                 Foreign securities are subject to special
                                 risks. Foreign stock markets can be extremely
                                 volatile. The liquidity of foreign securities
                                 may be more limited than domestic securities,
                                 which means that the Fund may, at times, be
                                 unable to sell foreign securities at desirable
                                 prices. Fluctuations in currency exchange rates
                                 may impact the value of foreign securities.
                                 Brokerage commissions, custodial fees and other
                                 fees are generally higher for foreign
                                 investments. In addition, foreign governments
                                 may impose withholding taxes which would reduce
                                 the amount of income available to distribute to
                                 shareholders. Other risks include the
                                 following: possible delays in the settlement of
                                 transactions; less publicly available
                                 information about companies; the impact of
                                 political, social or diplomatic events; and
                                 possible seizure, expropriation or
                                 nationalization of the company or its assets.
                                 The risks of foreign investments are typically
                                 increased in less developed and developing
                                 countries, which are sometimes referred to as
                                 emerging markets. For example, political and
                                 economic structures in these countries may be
                                 new and developing rapidly, which may cause
                                 instability. These countries are also more
                                 likely to experience high levels of inflation
                                 or currency devaluations, which could hurt
                                 their economies and securities markets.



                                 Structure risk is the risk that an event will
                                 occur (such as a security being prepaid or
                                 called) that alters the security's cashflows.
                                 Prepayment risk is a particular type of
                                 structure risk that is present in the Fund
                                 because of its investments in mortgage- and
                                 other asset-backed securities. Prepayment risk
                                 is the possibility that, as interest rates
                                 fall, homeowners (or other borrowers) are more
                                 likely to refinance their home mortgages (or
                                 other debt). When mortgages are refinanced, the
                                 principal on mortgage-backed securities is paid
                                 earlier than expected. In an environment of
                                 declining interest rates, mortgage- and other
                                 asset-backed securities may offer less
                                 potential for gain than any other debt
                                 securities. During periods of rising interest
                                 rates, mortgage- and other asset-backed
                                 securities have a high risk of declining in
                                 price because the declining prepayment rates
                                 effectively increase the maturity of
                                 securities. In addition, the potential impact
                                 of prepayment on the price of a mortgage- or
                                 other asset-backed security may be difficult to
                                 predict and result in greater volatility.



                                 Issuer risk is the possibility that changes in
                                 the financial condition of the issuer of a
                                 security, changes in general economic
                                 conditions or changes in economic conditions
                                 that affect the issuer's industry may impact
                                 the issuer's ability to make timely payment of
                                 interest or principal. Because the Fund may
                                 invest in fixed income securities issued by
                                 private entities, including


                                        3
<PAGE>   7


                                 certain types of corporate bonds, the Fund is
                                 subject to issuer risk. This could result in
                                 decreases in the price of the security. Lower
                                 rated securities have increased risk that the
                                 issuer of the security may default and not make
                                 payments of interest or principal.



                                 Management risk, which exists in varying
                                 amounts in most mutual funds, refers to the
                                 possibility that the Advisor may fail to
                                 anticipate market movements and the risks
                                 described herein, or to execute the Fund's
                                 strategy effectively.



                                 Closed-End Fund Risk.  The Fund is a closed-end
                                 investment company designed primarily for
                                 long-term investors and not as a trading
                                 vehicle. The Fund does not intend to list its
                                 shares for trading on any national securities
                                 exchange. There is not expected to be any
                                 secondary trading market in the shares and the
                                 shares should be considered illiquid (i.e. not
                                 readily marketable). The shares of closed-end
                                 investment companies often trade at a discount
                                 from their net asset values and, in the
                                 unlikely event that a secondary market for the
                                 Fund's shares were to develop, the shares
                                 likewise may trade at a discount from net asset
                                 value.



INVESTMENT ADVISOR............   Colonial Management Associates, Inc., an
                                 investment adviser registered under the
                                 Investment Advisers Act of 1940, has served as
                                 the Fund's Advisor since the Fund's inception.
                                 The Advisor is a wholly-owned subsidiary of
                                 Liberty Financial Companies, Inc., which is an
                                 indirect, majority-owned subsidiary of Liberty
                                 Mutual Insurance Company.



DISTRIBUTIONS.................   Income dividends are normally declared each
                                 business day, paid monthly, and confirmed at
                                 least quarterly. Capital gains, if any, are
                                 distributed at least annually, usually in
                                 December. Income dividends and capital gains
                                 distributions may be received in cash or
                                 reinvested in additional full and fractional
                                 shares of the Fund.



PERIODIC TENDER OFFERS........   The Fund has adopted a fundamental policy to
                                 offer each calendar quarter to repurchase a
                                 specified percentage (generally between 5% and
                                 25%) of the shares then outstanding at net
                                 asset value. Such repurchase offers are
                                 referred to as Tender Offers. Tender Offers are
                                 scheduled to occur on the 15th day (or the next
                                 business day if the 15th is not a business day)
                                 in the months of January, April, July and
                                 October. The Fund anticipates that its first
                                 Tender Offer will be in July, 2000.

                                 (See "Periodic Tender Offers.")

(1) Financial advisors may independently charge additional fees for shareholder
    transactions or for advisory services. Please see their materials for
    details.


(2) Class B shares will automatically convert to Class A shares eight years
    after purchase.


(3) The maximum EWC on Class B shares applies for repurchases during the first
    year. The charge is 3.25% for shares submitted and accepted for repurchase
    during the first year after each purchase, 3.00% during the second year,
    2.00% during the third year, 1.50% during the fourth year, and 1.00% during
    the fifth year. There is no EWC on Class B shares thereafter. The EWC on
    Class C shares is 1% within the first year from each purchase. There is no
    EWC on Class C shares thereafter.


(4) Management fees includes both the management fee and the administrative fee
    charged to the Fund.



(5) Colonial Management Associates, Inc. has contractually undertaken to waive
    its management fee and/or reimburse the Fund for its operating expenses to
    the extent that such expenses exceed the annual rates of 0.90% for Class A
    shares, 1.35% for Class B shares, and 1.50% for Class C shares,
    respectively, through December 31, 2000. In addition, Colonial Management
    Associates, Inc. has undertaken to waive its management fee and/or reimburse
    the Fund for its operating expenses to the extent that such expenses exceed
    the annual rates of 0.65% for Class A shares, 1.10% for Class B shares and
    1.25% for Class C shares, respectively, through April 30, 2000. Any such
    reimbursement will lower the particular class's overall expense ratio and
    increase its overall return to investors.



(6) Class A shares bought without an initial sales charge in accounts
    aggregating $1 million to $5 million are subject to a 1.00% EWC if the
    shares are sold within 18 months of the time of each purchase. The 18-month
    period begins on the first day of the month following each purchase.

EXAMPLE.  This Example helps you compare the cost of investing in the Fund to
the cost of investing in other mutual funds. The Example assumes that (i) you

                                    THE FUND



     The Fund is a closed-end, diversified management investment company. The
Fund's primary investment objective is to provide high current income. The
Fund's secondary investment objective is to seek total return. No assurance can
be given that the Fund's investment objectives will be achieved. The Fund was
organized as a Massachusetts business trust under the laws of the Commonwealth
of Massachusetts on November 16, 1999, and is registered under the Investment
Company Act of 1940. The Fund's principal office is located at One Financial
Center, Boston, Massachusetts 02111, and its telephone number is 800-422-3737.


                                USE OF PROCEEDS


     The net proceeds from the sale of the shares offered hereby will be
invested in accordance with the Fund's investment objectives and policies. It is
presently anticipated that the Fund will be able to invest substantially all of
the net proceeds in securities that meet the Fund's investment objectives at or
shortly after it commences operations. To the extent that all of the proceeds
cannot be so invested, pending such investment, the Fund will invest such
proceeds initially in high-quality, short-term money market securities.



                     OTHER INVESTMENT STRATEGIES AND RISKS



USE OF LEVERAGE AND RELATED RISKS



     The Fund's use of reverse repurchase agreements, short-sales and other
derivative instruments to leverage its portfolio creates special risks not
associated with unleveraged funds having similar investment objectives and
policies, including a higher volatility of the net asset value of the shares and
potentially more volatility in the market value of the shares. Any investment
income or gains earned by the Fund on amounts effectively borrowed that is in
excess of what the Fund effectively pays as interest will cause the value of and
dividends, if any, on the Fund's shares to rise more quickly than would
otherwise be the case. Conversely, if the investment performance by the Fund on
leverage fails to cover the interest on such leverage, the value of the shares
may decrease more quickly than would otherwise be the case and dividends thereon
will be reduced or eliminated. This is the speculative effect of "leverage."



     If the Fund's current investment income were not sufficient to meet
interest payments on the leverage, it could be necessary for the Fund to
liquidate certain of its investments, thereby reducing the net asset value
attributable to the shares. In addition, a decline in the net asset value of the
Fund's investments may affect the ability of the Fund to make dividend payments
on its shares and such failure to


                                        6
<PAGE>   10


pay dividends or make distributions may result in the Fund ceasing to qualify as
a regulated investment company under the Internal Revenue Code of 1986, as
amended, (the "Code").



     Successful use of a leveraging strategy may depend on the Advisor's ability
to correctly predict interest rates and market movements, and there is no
assurance that a leveraging strategy will be successful during any period in
which it is employed.


HEDGING STRATEGIES


     The Fund may enter into a number of hedging strategies, including futures
and options, to gain or reduce exposure to particular securities or markets.
These strategies, which are commonly referred to as derivatives, involve the use
of financial instruments whose value derives from the future, not current,
performance of an underlying security, index or currency. The Fund will use
these strategies for hedging purposes (attempting to offset a potential loss in
one position by establishing an interest in an opposite position) in connection
with the Fund's bond holdings or to adjust the duration of the Fund's bond
holdings. Hedging strategies involve the risk that they may exaggerate a loss,
potentially losing more money than the actual cost of the security, or limit a
potential gain. Also, with some hedging strategies there is the risk that the
other party to the transaction may fail to honor its contract terms, causing a
loss to the Fund.


WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS


     When-issued securities and forward commitments are securities which are
purchased prior to the date they are actually issued or delivered. These
securities involve the risk that they may fall in value by the time they are
actually issued or that the other party may fail to honor the contract terms. In
a dollar roll, the Fund sells a mortgage-backed security and simultaneously
enters into a commitment to purchase a similar security at a later date.


SHORT SALES


     A short sale is effected by selling a security that the Fund does not own,
or, if the Fund does own such security, it is not to be delivered upon
consummation of the sale. A short sale is "against the box" to the extent that
the Fund contemporaneously owns or has the right to obtain securities identical
to those sold short without payment. If the price of the security sold short
increases between the time of the short sale and the time the Fund replaces the
borrowed security, the Fund will incur a loss; conversely, if the price
declines, the Fund will realize a gain. Because the Fund's loss on a short sale
arises from increases in the value of the security sold short, such loss, like
the price of the security sold short, is theoretically unlimited.


REVERSE REPURCHASE AGREEMENTS


     The Fund may enter into reverse repurchase agreements by selling securities
and simultaneously agreeing to buy them back at a later date at a price equal to
the price paid to the Fund, together with an amount representing interest on
such amounts. Reverse repurchase agreements involve the risk that the market
value of the securities sold by the Fund may decline below the repurchase price
of the securities and, if the proceeds from the reverse repurchase agreement are
invested in securities, that the value of the securities bought may decline at
the same time there is a decline in the securities sold (and required to be
repurchased.)


ZERO COUPON BONDS


     The Fund may invest in zero coupon bonds. Zero coupon bonds are issued at
less than their face value and do not make any payments of interest. As a
result, these bonds include greater credit risk and are subject to greater
volatility than bonds that pay cash interest on a current basis.


                                        7
<PAGE>   11

TEMPORARY DEFENSIVE STRATEGIES


     The Advisor may determine that adverse market conditions make it desirable
to temporarily suspend the Fund's normal investment activities. During such
times, the Fund may invest in cash, high-quality, short-term debt securities, or
any other securities without limit. Taking a temporary defensive position may
prevent the Fund from achieving its goals.



     In seeking to achieve its goals, the Fund may invest in various types of
securities and engage in various investment techniques which are not the
principal focus of the Fund and therefore are not described in this prospectus.
These types of securities and investment practices are identified and discussed
in the SAI, which you may obtain by contacting the Distributor at
1-800-422-3737.



                             MANAGEMENT OF THE FUND



TRUSTEES AND OFFICERS



     The Board of Trustees is responsible for the general supervision of the
Fund, including general supervision of the duties performed by the Advisor under
its Management Agreement with the Fund. There are twelve Trustees of the Fund,
one of whom is an "interested person" (as defined in the Investment Company Act
of 1940) of the Fund, the Advisor or the Distributor. The names and addresses of
the trustees and officers of the Fund and their principal occupations and other
affiliations during the past five years are set forth under "Management of the
Fund" in the Statement of Additional Information.


THE ADVISOR


     The Advisor is Colonial Management Associates, Inc., a Massachusetts
corporation having its principal offices at One Financial Center, Boston,
Massachusetts 02111. The Advisor is a wholly-owned subsidiary of Liberty
Financial Companies, Inc. ("LFC") and both LFC and the Advisor are indirect,
majority-owned subsidiaries of Liberty Mutual Insurance Co., an underwriter of
workers' compensation insurance and a property and casualty insurer in the
United States. The Advisor has been an investment adviser since 1931. As of the
date of this Prospectus, the Advisor serves as investment adviser or sub-
adviser for 38 open-end and 8 closed-end management investment companies and
manages over $15 billion in assets.



     The Advisor's investment advisory business is managed together with the
mutual funds and institutional investment advisory business of its affiliate,
Stein Roe & Farnham Incorporated ("Stein Roe"). The Advisor is part of a larger
business unit that includes several separate legal entities known collectively
as Liberty Funds Group ("LFG"). The Advisor, Stein Roe and other LFG entities
also share personnel, facilities and systems that may be used in providing
administrative services to the Fund. Stein Roe is a registered investment
adviser. The Advisor, Stein Roe and the other entities that make up LFG are
subsidiaries of LFC.



     Leslie W. Finnemore, and Michael Bissonnette, each a senior vice president
of the Advisor, will co-manage the Fund. Since 1987, Ms. Finnemore has served as
a manager or co-manager of various other taxable income funds that the Advisor
manages.



     Mr. Bissonnette is a co-manager for other taxable income funds that the
Advisor manages. Prior to joining the Advisor, Mr. Bissonnette was a portfolio
manager for APAM Inc. from June, 1998 to June, 1999 and a portfolio manager at
Caxton Corporation from July, 1996 to June, 1998. From June, 1993 to June, 1996
Mr. Bissonnette served as a portfolio manager of fixed-income funds and a vice
president of the Advisor.



MANAGEMENT AGREEMENT



     The Management Agreement between the Advisor and the Fund (the "Management
Agreement") provides that, subject to the direction of the Board of Trustees of
the Fund and the applicable provisions of the Investment Company Act of 1940,
the Advisor is responsible for the actual management of the Fund's portfolio.
The responsibility for making decisions to buy, sell or hold a particular
investment rests with the Advisor, subject to review by the Board of Trustees of
the Fund and compliance with the applicable provisions of the Investment Company
Act of 1940 (the "1940 Act").


                                        8
<PAGE>   12


     The Advisor provides the Fund with accounting, bookkeeping and pricing
services and other services and office facilities (the expenses of which are
borne by the Fund as specified below), except to the extent these services are
provided by an administrator or an accounting firm hired by the Fund.



     Under the Management Agreement with the Fund, the Advisor receives a
monthly advisory fee at the annual rate of 0.50% of the average weekly net
assets of the Fund, including amounts borrowed from banks for investment
purposes. There are no current plans to utilize leverage through bank
borrowings. The Fund will not borrow from banks unless the Fund's Board of
Trustees approves the terms of the borrowing.



     The Advisor places all orders for the purchase and sale of portfolio
securities. In selecting broker-dealers, the Advisor may consider research and
brokerage services furnished by such broker-dealers to the Advisor and its
affiliates. In recognition of the research and brokerage services provided, the
Advisor may cause the Fund to pay the selected broker-dealer a higher commission
than would have been charged by another broker-dealer not providing such
services. Subject to seeking best execution, the Advisor may consider sales of
shares of certain funds distributed by affiliates of the Advisor in selecting
broker-dealers for portfolio security transactions.



     In addition to the fee of the Advisor, the Fund pays all other costs and
expenses of its operations, including compensation of its trustees (other than
those affiliated with the Advisor), custodian, transfer and dividend disbursing
expenses, legal fees, expenses of independent auditors, expenses of repurchasing
shares, shareholder reports, expenses of preparing, printing and distributing
notices, proxy statements and reports to governmental agencies, and taxes, if
any.


                        DETERMINATION OF NET ASSET VALUE


     The net asset value of the Fund's shares will be determined as of the close
of regular trading on the NYSE (generally 4:00 p.m. Eastern time). The net asset
value of the Fund equals the value of the Fund's assets less the Fund's
liabilities divided by the total number of outstanding shares. Portfolio
securities for which market quotations are readily available are valued at
current market value. Short-term investments maturing in 60 days or less are
valued at amortized cost when the Advisor determines, pursuant to procedures
adopted by the Board of Trustees, that such cost approximates current market
value. All other securities and assets are valued at their fair value following
procedures adopted by the Board of Trustees.



     In determining the value of securities for which market quotations are not
readily available, the Fund's custodian utilizes the valuations furnished by a
pricing service approved by the Board of Trustees. The pricing service uses
methods which include consideration of the following: yields or prices of
securities of comparable quality, type of issue, coupon, maturity and rating;
indications as to value from dealers; and general market conditions. The pricing
service may employ electronic data processing techniques or a matrix system, or
both, to determine valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Trustees.



     The Fund translates prices for its investments quoted in foreign currencies
into U.S. dollars at current exchange rates. As a result, changes in the value
of those currencies in relation to the U.S. dollar may affect the Fund's net
asset value. If events materially affecting the values of the Fund's foreign
investments occur between the close of foreign markets and the close of regular
trading on the NYSE, these investments may be valued at their fair value.


                     ORGANIZATION AND DESCRIPTION OF SHARES


     The Fund is a Massachusetts business trust organized under an Agreement and
Declaration of Trust ("Declaration of Trust") dated November 16, 1999, as
amended which provides that each shareholder shall be deemed to have agreed to
be bound by the terms thereof. The Declaration of Trust may be


                                        9
<PAGE>   13


amended by a vote of either the Fund's shareholders or its Trustees. The Fund
offers four classes of shares: Class A, Class B, Class C and Class Z.



     Under Massachusetts law, shareholders of a Massachusetts business trust
such as the Fund could, in some circumstances, be held personally liable for
unsatisfied obligations of the Fund. However, the Declaration of Trust provides
that persons extending credit to, contracting with, or having any claim against
the Fund shall look only to its assets for payment under such credit, contract
or claim, and that the shareholders, trustees and officers of the Fund shall
have no personal liability therefor. The Declaration of Trust requires that
notice of such disclaimer of liability be given in each contract, instrument or
undertaking executed or made on behalf of the Fund. Further, the Declaration of
Trust provides for indemnification of any shareholder against any loss and
expense arising from personal liability solely by reason of being or having been
a shareholder. Thus, the risk of a shareholder incurring financial loss on
account of shareholder liability is believed to be remote, because it would be
limited to circumstances in which the disclaimer was inoperative and the Fund
was unable to meet its obligations.



     The shares are not, and are not expected to be, listed for trading on any
national securities exchange nor, to the Fund's knowledge, is there, or is there
expected to be, any secondary trading market in the shares.



     STATUS OF SHARES.  The Fund is authorized to issue an unlimited number of
shares. The Board of Trustees may classify or reclassify any issued or unissued
shares of the Fund into shares of any class by redesignating such shares or by
setting or changing in any one or more respects, from time to time, prior to the
issuance of such shares, the preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications, or terms or
conditions or repurchase of such shares. Any such classification or
reclassification will comply with the provisions of the 1940 Act. As of January
14, 2000, the following shares of the Fund were outstanding:

                            MULTIPLE PRICING SYSTEM


     CHOOSING A SHARE CLASS.  The Fund offers three classes of shares in this
prospectus: Class A, B and C. Each share class has its own sales charge and
expense structure. Determining which share class is best for you depends on the
dollar amount you are investing and the number of years for which you are
willing to invest. Purchases of $1 million or more are automatically invested in
Class A shares. Based on your personal situation, your financial advisor can
help you decide which class of shares makes the most sense for you. The Fund
also offers Class Z shares, which are available only to institutional and other
investors through a separate prospectus.



     SALES CHARGES.  You may be subject to an initial sales charge when you
purchase or an early withdrawal charge ("EWC") when you tender shares of the

sales charges are waived, as described below and in the SAI.


     CLASS A SHARES.  Your purchases of Class A shares generally are at the
public offering price. This price includes a sales charge that is based on the
amount of your initial investment when you open your

account. The sales charge you pay on additional investments is based on the
amount of your additional purchase, plus the current value of your account. The
amount of the sales charge differs depending on the amount you invest as shown
in the table below. The table below also shows the commission paid to the
financial advisor firm on sales of Class A shares.

* Class A shares bought without an initial sales charge in accounts aggregating
  $1 million to $5 million are subject to a 1.00% EWC if the shares are sold
  within 18 months of the time of each purchase. Shareholders who purchase in
  accounts aggregating over $5 million are subject to a 1.00% EWC only to the
  extent that sales of shares within 18 months of a purchase cause the value of
  the accounts to fall below the $5 million level. The 18-month period begins on
  the first day of the month following each purchase.


     CLASS A SHARES.  For Class A share purchases of $1 million or more,
financial advisors receive a commission from the Distributor as follows:

     REDUCED SALES CHARGES FOR LARGER INVESTMENTS.  There are two ways for you
to pay a lower sales charge when purchasing Class A shares. The first is through
Rights of Accumulation. If the combined value of the Fund accounts maintained by
you, your spouse or your minor children reaches a discount level (according to
the chart on the previous page), your next purchase will receive the lower sales
charge. The second is by signing a Statement of Intent within 90 days of your
purchase. By doing so, you would be able to pay the lower sales charge on all
purchases by agreeing to invest a total of at least $100,000 within 13 months.
If your Statement of Intent purchases are not completed within 13 months, you
will be charged the applicable sales charge. In addition, certain investors may
purchase Class A shares at a reduced sales charge or net asset value, which is
the value of a Fund share excluding any sales charges. See the SAI for a
description of these situations.



     CLASS B SHARES.  Your purchases of Class B shares are at the Fund's net
asset value. Class B shares have no front-end sales charge, but carry an EWC
that is imposed only on shares sold prior to the completion of the periods shown
in the chart below. The Distributor pays the financial advisor firm an up-front
commission of 3.25% on sales of Class B shares.

     The EWC generally declines each year and eventually disappears. Class B
shares automatically convert to Class A shares after eight years and after that
date, Class B shares will no longer be subject to the distribution fees
applicable to Class B shares. Conversion will be on the basis of the relative
net asset values per share, without the imposition of any sales charge, fee or
other charge. The purpose of the conversion feature is to relieve the holders of
Class B shares from asset-based distribution expenses applicable to such shares
at such time as the Class B shares have been outstanding long enough for the
Distributor to have been substantially compensated for distribution-related
expenses incurred in connection with those shares. Class C shares do not convert
to Class A shares.



     CLASS C SHARES.  Similar to Class B shares, your purchases of Class C
shares are at the Fund's net asset value. Although Class C shares have no
front-end sales charge, they carry an EWC of 1.00% that is applied to shares
sold within the first year after they are purchased. After holding shares for
one year, you may tender them without paying an EWC. Class C shares do not
convert into Class A shares. Therefore, holders of Class C shares will continue
to bear the asset-based distribution fees applicable to Class C shares for as
long as they hold such shares. The Distributor pays the financial advisor firm
an up-front commission of 1.00% on sales of Class C shares.



     EARLY WITHDRAWAL CHARGES ("EWC").  Certain investments in Class A, B and C
shares are subject to an EWC. You will pay the EWC only on shares you tender
within a certain amount of time after purchase. The EWC generally declines each
year until there is no charge for tendering shares. The EWC is applied to the
net asset value at the time of purchase or repurchase, whichever is lower. For
purposes of calculating the EWC, the start of the holding period is the first
day of the month following each purchase. Shares you purchase with reinvested
dividends or capital gains are not subject to an EWC. When shares are
repurchased, the Fund will automatically repurchase those shares not subject to
an EWC and then those you have held the longest. This policy helps reduce and
possibly eliminate the potential impact of the EWC. In certain circumstances,
EWCs may be waived, as described in the SAI.



     DISTRIBUTION AND SERVICE FEES.  In addition to an EWC, each class of shares
is authorized under a distribution plan (Plan) to use the assets attributable to
a class to finance certain activities relating to the distribution of shares to
investors. These include marketing and other activities to support the
distribution of the Class A, B, and C shares and the services provided to you by
your financial advisor. The Plan was approved and reviewed in a manner
consistent with Rule 12b-1 under the 1940 Act, which regulates the manner in
which an open-end investment company may directly or indirectly bear the
expenses of distributing its shares. Although the Fund is not an open-end
investment company, it has undertaken to comply with the terms of Rule 12b-1 as
a condition of an exemptive order under the 1940 Act to permit it to have a
multi-class structure, EWCs, and distribution fees.



     Under the Plan, the Fund pays the Distributor monthly distribution and
service fees at an annual rate of up to 0.25% of average daily net assets
attributable to Class A shares, 0.70% of average daily net assets attributable
to Class B shares, and 0.85% of average daily net assets attributable to Class C
shares, respectively. Since the distribution and service fees are payable
regardless of the Distributor's expenses, the Distributor may realize a profit
from the fees. The Plan authorizes any other payments by the Fund to the
Distributor and its affiliates to the extent that such payments might be
construed to be indirect financing of the distribution of Fund shares.



     The Trustees believe that the Plan could be a significant factor in the
growth and retention of Fund assets, resulting in a more advantageous expense
ratio and increased investment flexibility which could benefit each class of
Fund shareholders. The Plan will continue in effect from year to year so long as
its continuance is specifically approved at least annually by a vote of the
Trustees, including the Trustees who are not interested persons of the Fund and
who have no direct or indirect financial interest in the operation of the Plan
or in any agreements related to the Plan ("Independent Trustees"), cast in
person at a meeting called for the purpose of voting on the Plan. The Plan may
not be amended to increase the fee materially without approval by a vote of a
majority of the outstanding voting securities of the relevant class of shares
and all material amendments of the Plan must be approved by the Trustees in the
manner provided in the foregoing sentence. The Plan may be terminated at any
time by a vote of a majority of the


                                       13
<PAGE>   17


Independent Trustees or by a vote of a majority of the outstanding voting
securities of the relevant class of shares. The continuance of the Plan will
only be effective if the selection and nomination of the Independent Trustees is
effected by such Independent Trustees.



     HOW TO EXCHANGE SHARES.  Shareholders of the Fund whose shares are
repurchased during a Tender Offer may exchange those shares for shares of the
same class of a Fund distributed by the Distributor at net asset value. Fund
shareholders will not be able to participate in this exchange privilege at any
time other than in connection with a Tender Offer. If your shares are subject to
an EWC, you will not be charged an EWC upon the exchange. However, when you sell
the shares acquired through the exchange, the shares sold may be subject to a
CDSC (a CDSC is the deferred sales charge applicable to the open-end funds) or
EWC, depending upon when you originally purchased the shares you exchanged. For
purposes of computing the CDSC or EWC, the length of time you have owned your
shares will be computed from the date of your original purchase and the
applicable CDSC or EWC will be the EWC of the Fund or for Fund shares purchased
by exchange, the original Liberty fund.



     Unless your account is part of a tax-deferred retirement plan, an exchange
is a taxable event. Therefore, you may realize a gain or a loss for tax
purposes. The Fund may terminate your exchange privilege if the Advisor
determines that your exchange activity is likely to adversely impact its ability
to manage the Fund.


                             PERIODIC TENDER OFFERS


     The Board has adopted share repurchase policies as fundamental policies.
Those policies, which may not be changed without the vote of the holders of a
majority of the Fund's outstanding voting securities, provide that each calendar
quarter, the Fund will make a Tender Offer to repurchase a portion of the
outstanding shares from shareholders who request repurchase.



     REPURCHASE PROCEDURE.  At the beginning of each Tender Offer, shareholders
will be notified in writing about the Tender Offer, how they may request that
the Fund repurchase their shares and the deadline for shareholders to provide
their repurchase requests to the Distributor (the "Repurchase Request
Deadline"), which is the date the Tender Offer ends. The time between the
notification of the shareholders and the Repurchase Request Deadline may vary
from no more than six weeks to no less than three weeks. For each Tender Offer,
it is anticipated that each Repurchase Request Deadline will be on the 15th day
in each of the months of January, April, July and October, or, if the 15th day
is not a business day, the next business day. The repurchase price of the shares
will be the net asset value as of the close of regular trading on the NYSE on
the date on which the repurchase price of shares will be determined (the
"Repurchase Pricing Date"). It is anticipated that normally the Repurchase
Pricing Date will be the same date as the Repurchase Request Deadline, and if
so, the Repurchase Request Deadline will be set for a time no later than the
close of regular trading on the NYSE on such date. The Fund has determined that
the Repurchase Pricing Date may occur no later than the 14th day after the
Repurchase Request Deadline or the next business day if the 14th day is not a
business day.


     The Board may establish other policies for repurchases of shares that are
consistent with the 1940 Act and other pertinent laws. Shares tendered by
shareholders by any Repurchase Request Deadline will be repurchased subject to
the aggregate repurchase amounts established for that Repurchase Request
Deadline. Repurchase proceeds will be paid to shareholders in cash within seven
days after each Repurchase Pricing Date. The end of the seven days is referred
to as the "Repurchase Payment Deadline."


     Repurchase offers and the need to fund repurchase obligations may affect
the ability of the Fund to be fully invested, which may reduce returns.
Moreover, diminution in the size of the Fund through repurchases without
offsetting new sales may result in untimely sales of portfolio securities and a
higher expense ratio, and may limit the ability of the Fund to participate in
new investment opportunities. The Fund may borrow to meet repurchase
obligations, which entails certain risks and costs. The Fund may also sell
portfolio securities to meet repurchase obligations which, in certain
circumstances, may adversely affect the market for portfolio securities and
reduce the Fund's value.


                                       14
<PAGE>   18


     REPURCHASE AMOUNTS.  The Board, in its sole discretion, will determine the
number of shares that the Fund will offer to repurchase (the "Tender Offer
Amount") for a given Repurchase Request Deadline. However, the Tender Offer
Amount will generally be at least 5% and no more than 25% of the total number of
shares outstanding on the Repurchase Request Deadline.



     If shareholders tender more than the Tender Offer Amount for a given Tender
Offer, the Fund may repurchase an additional amount of shares of up to 2% of the
shares outstanding on the Repurchase Request Deadline. If the Fund determines
not to repurchase more than the Tender Offer Amount, or if the Fund determines
to repurchase the additional 2% of the shares outstanding, but Fund shareholders
tender shares in excess of that amount, the Fund will repurchase the shares on a
pro rata basis and shareholders would be unable to sell in the Tender Offer all
or a portion of their shares tendered. The Fund may, however, accept all shares
tendered by shareholders who own less than 100 shares and who tender all their
shares, before accepting on a pro rata basis shares tendered by other
shareholders.



     NOTICES TO SHAREHOLDERS.  Notice of each quarterly Tender Offer (and any
additional discretionary repurchase offers) will be given to each beneficial
owner of shares between 21 and 42 days before each Repurchase Request Deadline.
The notice will contain information shareholders should consider in deciding
whether or not to tender their shares. The notice will also include detailed
instructions on how to tender shares. The notice will state the Tender Offer
Amount. The notice will also identify the dates of the Repurchase Request
Deadline, scheduled Repurchase Pricing Date, and scheduled Repurchase Payment
Deadline. The notice will describe the risk of fluctuation in the net asset
value between the Repurchase Request Deadline and the Repurchase Pricing Date,
if such dates do not coincide, and the possibility that the Fund may use an
earlier Repurchase Pricing Date than the scheduled Repurchase Pricing Date under
certain circumstances (if the scheduled Repurchase Pricing Date is not the
Repurchase Request Deadline). The notice will describe (i) the procedures for
shareholders to tender their shares, (ii) the procedures for the Fund to
repurchase shares on a pro rata basis, (iii) the circumstances in which the Fund
may suspend or postpone a Tender Offer, and (iv) the procedures that will enable
shareholders to withdraw or modify their tenders of shares until the Repurchase
Request Deadline. The notice will set forth the net asset value of the shares to
be repurchased no more than seven days before the date of notification, and how
shareholders may ascertain the net asset value after the notification date.


     REPURCHASE PRICE.  The notice of the Tender Offer will also provide
information concerning the net asset value per share, such as the net asset
value as of a recent date or a sampling of recent net asset values, and a
toll-free number for information regarding the Tender Offer.


     SUSPENSION OR POSTPONEMENT OF REPURCHASE OFFER.  The Fund may, with the
approval of a majority of the Trustees who are not "interested persons" (as
defined in the 1940 Act) of the Fund, suspend or postpone a repurchase offer
only: (A) if making or effecting the repurchase offer would cause the Fund to
lose its status as a regulated investment company under the Internal Revenue
Code; (B) for any period during which the NYSE or any market on which the
securities owned by the Fund are principally traded is closed, other than
customary weekend and holiday closings, or during which trading in such market
is restricted; (C) for any period during which an emergency exists as a result
of which disposal by the Fund of securities owned by it is not reasonably
practicable, or during which it is not reasonably practicable for the Fund
fairly to determine the value of its net assets; or (D) for such other periods
as the Securities and Exchange Commission may by order permit for the protection
of shareholders of the Fund.



     LIQUIDITY REQUIREMENTS.  The Fund must maintain liquid assets equal to the
Tender Offer Amount from the time that the notice is sent to shareholders until
the Repurchase Pricing Date. The Fund will ensure that a percentage of its net
assets equal to at least 100% of the Tender Offer Amount consists of assets (a)
that can be sold or disposed of in the ordinary course of business at
approximately the price at which the Fund has valued the investment within the
time period between the Repurchase Request Deadline and the Repurchase Payment
Deadline; or (b) that mature by the Repurchase Payment Deadline.



     The Board of Trustees has adopted procedures that are reasonably designed
to ensure that the Fund's assets are sufficiently liquid so that it can comply
with the Tender Offer and the liquidity requirements

                                       15
<PAGE>   19


described in the previous paragraph. If, at any time, the Fund falls out of
compliance with these liquidity requirements, the Board will take whatever
action it deems appropriate to ensure compliance.


                                  TAX MATTERS


     The following federal tax discussion reflects provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), existing Treasury regulations,
rulings published by the Internal Revenue Service, and other applicable
authority, as of the date of this Prospectus. These authorities are subject to
change by legislative or administrative action. The following discussion is only
a summary of some of the important federal tax considerations generally
applicable to investments in the Fund. There may be other tax considerations
applicable to particular investors. In addition, income earned through an
investment in the Fund may be subject to foreign, state and local taxes.
Prospective shareholders are therefore urged to consult their tax advisors with
respect to the tax consequences to them of an investment in the Fund. For more
information on federal income tax considerations, see "Tax Matters" in the
Statement of Additional Information.



FEDERAL TAXATION OF THE FUND



     The Fund intends to qualify each year for taxation as a regulated
investment company under Subchapter M of the Code. If the Fund so qualifies, the
Fund will not be subject to federal income tax on income distributed in a timely
manner to Fund shareholders in the form of dividends or capital gain
distributions. The Fund intends to distribute all its net investment income and
all its net capital gains to shareholders at least annually. If the Fund is
determined not to have distributed all of its net investment income, it could
owe tax at the corporate level, and, in certain circumstances, lose its
eligibility to be treated as a regulated investment company. For more
information on the requirements the Fund must satisfy in order to qualify as a
regulated investment company, see "Tax Matters -- Federal Taxation of the Fund"
in the Statement of Additional Information.



     The Fund's investments and hedging activities are subject to special
federal tax rules. Federal rules governing the Fund's hedging transactions
(including hedging transactions in futures and options) may alter the character
of distributions to shareholders. The Fund's investments in securities issued at
a discount will (and investments in securities purchased at a discount may)
require the Fund to accrue and distribute income not yet received. Therefore, in
order to generate sufficient cash to make the requisite distributions, the Fund
may be required to sell securities in its portfolio that it otherwise would have
continued to hold.


FEDERAL TAXATION OF SHAREHOLDERS


     DIVIDENDS AND OTHER DISTRIBUTIONS.  Distributions of net investment income
(including the excess, if any, of net short-term capital gain over net long-term
capital loss), will be taxable to shareholders as ordinary income, and will not
qualify for the corporate dividends-received reduction. Distributions of net
capital gain will be taxable to shareholders as long-term capital gain
(generally, at a 20% rate for noncorporate shareholders), without regard to how
long a shareholder has held shares of the Fund, and will not qualify for the
corporate dividends-received deduction.



     Distributions of income and capital gain are taxable whether received in
cash or reinvested in additional shares. If a dividend or distribution is made
shortly after a shareholder purchases shares of the Fund, while in effect a
return of capital to the shareholder, the dividend or distribution is taxable,
as described above. This is called "buying a dividend" and should be avoided, if
possible.



     The Fund's net investment income calculated for accounting purposes and
distributed to shareholders may in certain circumstances exceed or be less than
the Fund's net tax-exempt and taxable income for federal tax purposes. If the
Fund distributes amounts in excess of the Fund's "earnings and profits" (which
provides the measure of the Fund's dividend-paying capacity for tax purposes),
such distributions to shareholders will be treated as a return of capital to the
extent of a shareholder's basis in his or her shares,


                                       16
<PAGE>   20


and thereafter as gain from the sale or exchange of a capital asset. A return of
capital is not taxable to a shareholder and has the effect of reducing a
shareholder's basis in the relevant shares, which basis reduction would cause
shareholders to realize gain if their shares were sold for an amount equal to
the purchase price.



     Any dividend paid by the Fund during January of a given year generally is
deemed to have been received by shareholders on December 31 of the preceding
year, provided that the dividend actually was declared by the Fund in October,
November or December of such preceding year and payable to shareholders of
record on a date in such a month.



     The Fund will notify shareholders each year of the amount and tax status of
dividends and other distributions, including the amount of any distribution of
net capital gain.



     SALE OR REDEMPTION OF SHARES.  In some circumstances, the sale or exchange
of shares in the Fund may give rise to gain or loss. In general, any gain or
loss realized upon a taxable disposition of shares in the Fund by a shareholder
will be treated as long-term capital gain or loss if the shares have been held
for more than twelve months, and otherwise as short-term capital gain or loss.
However, if a shareholder buys shares in the Fund and sells them at a loss
within six months, any loss will be disallowed for federal income tax purposes
to the extent of any exempt-interest dividends received on such shares. In
addition, any loss (not already disallowed as provided in the preceding
sentence) realized upon a taxable disposition of shares in the Fund held for six
months or less will be treated as long-term, rather than short-term, capital
loss to the extent of any net capital gain distributions received by the
shareholder with respect to those shares. All or a portion of any loss realized
upon a taxable disposition of shares in the Fund will be disallowed if other
shares in the Fund are purchased within 30 days before or after the disposition.
In such a case, the basis of the newly purchased shares in the Fund will be
adjusted to reflect the disallowed loss.



     Gain or loss, if any, resulting from a redemption of shares in the Fund
generally will be treated as gain or loss from the sale or exchange of a capital
asset under Section 302 of the Code, rather than as a dividend, but only if the
redemption distribution (i) is deemed not to be essentially equivalent to a
dividend, (ii) is in complete redemption of an owner's interest in the Fund,
(iii) is substantially disproportionate with respect to the owner, or (iv) with
respect to non-corporate owners, is in partial liquidation of the Fund.


       CUSTODIAN, TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR


     The Fund's securities and cash are held by The Chase Manhattan Bank, whose
principal business address is 270 Park Avenue, New York, New York 10017-2070, as
custodian under a custodian contract.



     Liberty Funds Services, Inc., P.O. Box 1722, Boston, Massachusetts 02105, a
wholly-owned subsidiary of LFG, is the agent of the Fund for the transfer of
shares, disbursement of dividends and maintenance of shareholder account
records.



                            REPORTS TO SHAREHOLDERS



     The Fund will send unaudited semiannual and audited annual reports to its
shareholders, including, as currently required by regulations of the Securities
and Exchange Commission (the "SEC"), a list of investments held.

    Colonial Investment Grade Bond Fund is a diversified, closed-end management
investment company that seeks, as its primary investment objective, to provide
high current income. The Fund's secondary investment objective is to seek total
return. Under normal circumstances, the Fund will invest at least 80% of its
assets in investment grade debt securities (debt securities that are rated at
least Baa/BBB or their equivalent by a rating agency or are determined by
Colonial Management Associates, Inc., the Fund's investment advisor (the
"Advisor"), to be of comparable quality). The Fund generally expects to maintain
an intermediate to long duration (approximately 3-7 years). The Fund may
leverage its portfolio, through certain derivative instruments, or otherwise,
when the Advisor believes it would benefit the Fund. The use of leverage
involves certain special risks. (See "Summary -- Special Risk Considerations --
Leverage Risk.") No assurance can be given that the Fund's investment objectives
will be achieved. An investment in the Fund is not appropriate for all
investors.

(1) The shares are continuously offered on a best efforts basis at a price equal
    to the net asset value per share next determined after receipt of a properly
    completed purchase order. It is expected that the initial net asset value
    per share of the Fund will be $12.00. The minimum initial investment is $1
    million, and the minimum subsequent investment is $50.



(2) Assumes the sale of all shares registered hereby, and the exclusion of
    approximately $271,020 of organizational and initial offering expenses
    payable by the Advisor.



    PERIODIC TENDER OFFERS.  To provide liquidity to shareholders, the Fund will
make quarterly repurchase offers, generally for 5% to 25% of its outstanding
shares. The time between the notification to shareholders of a tender offer and
the deadline for shareholders to provide their repurchase requests (the
"Repurchase Request Deadline") may vary from three to six weeks. The repurchase
price of the shares will be net asset value as of the close of regular trading
on the New York Stock Exchange ("NYSE") on the date on which the repurchase
price is determined (the "Repurchase Pricing Date"). The Repurchase Pricing Date
normally will be the same date as the Repurchase Request Deadline. Repurchase
proceeds generally will be paid to shareholders in cash within seven days after
each Repurchase Pricing Date. It is anticipated that the initial Repurchase
Request Deadline will be on July 17, 2000. (See "Periodic Tender Offers.")



    NOT EXCHANGE LISTED.  The Fund does not intend to list the shares on any
national securities exchange. Shares of the Fund have no history of public
trading and there is not expected to be any secondary trading market in the
shares. An investment in the shares should be considered illiquid. The shares of
closed-end investment companies often trade at a discount from their net asset
values and, in the unlikely event that a secondary market were to develop, the
Fund's shares likewise may trade at a discount from net asset value. (See
"Special Risk Considerations.")

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


    This prospectus applies to the offering of shares of beneficial interest of
the Fund, which may be continuously issued and sold from time to time by the
Fund through the Distributor, as distributor and principal underwriter, and
through your financial advisor. (See "How to Buy Shares.")



        The following eligible institutional investors may purchase Class Z
shares: (i) any retirement plan with aggregate assets of at least $5 million at
the time of purchase of Class Z shares and which purchases shares directly from
the Fund's distributor; (ii) any registered investment adviser purchasing shares
for its clients; (iii) any insurance company, fund company, investment company
or foundation; and (iv) any Trustee of the Fund, any employee of Colonial
Management Associates, Inc., or any of its affiliates, or any member of the
immediate family of any such Trustee or employee.

                               PROSPECTUS SUMMARY

     This summary highlights selected information from this Prospectus. It may
not contain all of the information that is important to you. You should read
this entire Prospectus carefully, including the risk factors. This summary is
qualified in its entirety by reference to the detailed information included in
this Prospectus and the Statement of Additional Information.


THE FUND......................   Colonial Investment Grade Bond Fund is a newly
                                 organized, diversified, closed-end management
                                 investment company. See "The Fund." The Fund
                                 was organized as a Massachusetts business trust
                                 on November 16, 1999 and has registered under
                                 the Investment Company Act of 1940.



                                 The Fund intends to offer its shares
                                 continuously through the Distributor, as
                                 principal underwriter, and through financial
                                 advisors at a price equal to the next
                                 determined net asset value per share. The
                                 minimum initial investment is $1 million and
                                 the minimum subsequent investment is $50. The
                                 Fund reserves the right to change the
                                 investment minimums and to refuse a purchase
                                 order for any reason.



CLASSES OF SHARES.............   The Fund offers Class Z shares in this
                                 prospectus.



INVESTMENT OBJECTIVES.........   The Fund's primary investment objective is to
                                 provide high current income. The Fund's
                                 secondary objective is to seek total return.



INVESTMENT STRATEGIES.........   The Fund seeks to achieve its investment goals
                                 by investing in:



                                      - Debt securities issued by the U.S.
                                        government or U.S. corporations
                                        (including mortgage- and other asset-
                                        backed securities); and


                                      - Debt securities issued by foreign
                                        governments or corporations.


                                 The Fund has wide flexibility to vary its
                                 allocation of investments among debt securities
                                 at any given time based on the Advisor's
                                 estimate of the expected performance and risk
                                 of each type of investment.



                                 The Fund may also invest to a lesser extent in
                                 common and preferred stocks to pursue its goal
                                 of total return.





                                 The Fund may, to the extent permitted by the
                                 Investment Company Act of 1940, "leverage" its
                                 portfolio by investing borrowed money when the
                                 Advisor believes it would benefit the Fund. The
                                 Fund has no current intention to leverage its
                                 portfolio through bank borrowings. The Fund may
                                 also, and currently expects to, leverage its
                                 portfolio through the use of reverse repurchase
                                 agreements, short sales and certain derivative
                                 instruments.



                                 Although the Fund normally invests at least 80%
                                 of its assets in investment grade debt
                                 securities, it may invest the remainder of


                                        1
<PAGE>   25

                                 its assets in lower-rated corporate debt
                                 securities. Lower-rated securities are:


                                      - rated below BBB by Standard & Poor's
                                        Rating Services, a division of The
                                        McGraw-Hill Companies, Inc. ("Standard &
                                        Poor's");



                                      - rated below BBB by Moody's Investor
                                        Services, Inc.;



                                      - assigned a comparable rating by another
                                        nationally recognized rating service; or



                                      - unrated and believed by the Advisor to
                                        be comparable in quality to a
                                        lower-rated debt security.



                                 The Fund may invest up to 35% of its assets in
                                 securities issued or guaranteed by foreign
                                 governments or foreign companies, including
                                 securities issued in emerging market countries.



                                 The Fund has adopted certain fundamental
                                 investment restrictions set forth in the
                                 Statement of Additional Information which may
                                 not be changed without approval by the Fund's
                                 shareholders. Except for such restrictions, and
                                 as otherwise specified, approval by the Fund's
                                 shareholders is not required to modify or
                                 change the Fund's goals or investment
                                 strategies.



SPECIAL RISK CONSIDERATIONS...   The primary risks of investing in the Fund are
                                 described below. There are many circumstances
                                 (that are not described here) which could cause
                                 you to lose money by investing in the Fund or
                                 prevent the Fund from achieving its goals.



                                 No operating history.  The Fund is a newly
                                 organized, closed-end investment company with
                                 no history of operations.



                                 Interest rate risk is the risk of a change in
                                 the price of a bond when interest rates change.
                                 In general, if interest rates rise, bond prices
                                 fall and if interest rates fall, bond prices
                                 rise. Changes in the values of bonds usually
                                 will not affect the amount of income the Fund
                                 receives from them but will affect the value of
                                 the Fund's shares. Interest rate risk is
                                 generally greater for bonds with longer
                                 maturities.



                                 Market risk is the risk that the price of a
                                 security held by the Fund will fall due to
                                 changing economic, political or market
                                 conditions, or due to the financial condition
                                 of the issuer of the security. Because stocks
                                 purchased by the Fund pay dividends only after
                                 payments are made to bond holders, the value of
                                 stocks usually will react more strongly than
                                 bonds to actual or perceived changes in the
                                 issuers' financial condition.



                                 Leverage risk.  The use of leverage through the
                                 purchase of certain derivative instruments or
                                 the use of reverse repurchase agreement or
                                 short sale transactions will create an
                                 opportunity for increased net income, but will
                                 also create special risks. The Fund intends to
                                 use leverage to provide the holders of the
                                 shares with a potentially higher return, but
                                 its leveraging strategy may not be successful.
                                 If the income from the securities purchased
                                 with leverage proceeds is not sufficient to
                                 cover the cost of


                                        2

                                 leverage, the Fund's return will be lower than
                                 if leverage had not been used. Leverage creates
                                 risks for holders of the shares, including the
                                 likelihood of greater volatility of the net
                                 asset value and market price of the shares.



                                 Foreign securities are subject to special
                                 risks. Foreign stock markets can be extremely
                                 volatile. The liquidity of foreign securities
                                 may be more limited than domestic securities,
                                 which means that the Fund may, at times, be
                                 unable to sell foreign securities at desirable
                                 prices. Fluctuations in currency exchange rates
                                 may impact the value of foreign securities.
                                 Brokerage commissions, custodial fees and other
                                 fees are generally higher for foreign
                                 investments. In addition, foreign governments
                                 may impose withholding taxes which would reduce
                                 the amount of income available to distribute to
                                 shareholders. Other risks include the
                                 following: possible delays in the settlement of
                                 transactions; less publicly available
                                 information about companies; the impact of
                                 political, social or diplomatic events; and
                                 possible seizure, expropriation or
                                 nationalization of the company or its assets.
                                 The risks of foreign investments are typically
                                 increased in less developed and developing
                                 countries, which are sometimes referred to as
                                 emerging markets. For example, political and
                                 economic structures in these countries may be
                                 new and developing rapidly, which may cause
                                 instability. These countries are also more
                                 likely to experience high levels of inflation
                                 or currency devaluations, which could hurt
                                 their economies and securities markets.



                                 Structure risk is the risk that an event will
                                 occur (such as a security being prepaid or
                                 called) that alters the security's cashflows.
                                 Prepayment risk is a particular type of
                                 structure risk that is present in the Fund
                                 because of its investments in mortgage- and
                                 other asset-backed securities. Prepayment risk
                                 is the possibility that, as interest rates
                                 fall, homeowners (or other borrowers) are more
                                 likely to refinance their home mortgages (or
                                 other debt). When mortgages are refinanced, the
                                 principal on mortgage-backed securities is paid
                                 earlier than expected. In an environment of
                                 declining interest rates, mortgage- and other
                                 asset-backed securities may offer less
                                 potential for gain than any other debt
                                 securities. During periods of rising interest
                                 rates, mortgage- and other asset-backed
                                 securities have a high risk of declining in
                                 price because the declining prepayment rates
                                 effectively increase the maturity of
                                 securities. In addition, the potential impact
                                 of prepayment on the price of a mortgage- or
                                 other asset-backed security may be difficult to
                                 predict and result in greater volatility.



                                 Issuer risk is the possibility that changes in
                                 the financial condition of the issuer of a
                                 security, changes in general economic
                                 conditions or changes in economic conditions
                                 that affect the issuer's industry may impact
                                 the issuer's ability to make timely payment of
                                 interest or principal. Because the Fund may
                                 invest in fixed income securities issued by
                                 private entities, including certain types of
                                 corporate bonds, the Fund is subject to issuer


                                        3

                                 risk. This could result in decreases in the
                                 price of the security. Lower rated securities
                                 have increased risk that the issuer of the
                                 security may default and not make payments of
                                 interest or principal.



                                 Management risk, which exists in varying
                                 amounts in most mutual funds, refers to the
                                 possibility that the Advisor may fail to
                                 anticipate market movements and the risks
                                 described herein, or to execute the Fund's
                                 strategy effectively.



                                 Closed-End Fund Risks.  The Fund is a
                                 closed-end investment company designed
                                 primarily for long-term investors and not as a
                                 trading vehicle. The Fund does not intend to
                                 list its shares for trading on any national
                                 securities exchange. There is not expected to
                                 be any secondary trading market in the shares
                                 and the shares should be considered illiquid
                                 (i.e. not readily marketable). The shares of
                                 closed-end investment companies often trade at
                                 a discount from their net asset values and, in
                                 the unlikely event that a secondary market for
                                 the Fund's shares were to develop, the shares
                                 likewise may trade at a discount from net asset
                                 value.



INVESTMENT ADVISOR............   Colonial Management Associates, Inc., an
                                 investment adviser registered under the
                                 Investment Advisers Act of 1940, has served as
                                 the Fund's Advisor since the Fund's inception.
                                 The Advisor is a wholly-owned subsidiary of
                                 Liberty Financial Companies, Inc., which is an
                                 indirect, majority-owned subsidiary of Liberty
                                 Mutual Insurance Company.


DISTRIBUTIONS.................   Income dividends are normally declared each
                                 business day, paid monthly, and confirmed at
                                 least quarterly. Capital gains, if any, are
                                 distributed at least annually, usually in
                                 December.


                                 Income dividends and capital gains
                                 distributions may be received in cash or
                                 reinvested in additional full and fractional
                                 shares of the Fund.



PERIODIC TENDER OFFERS........   The Fund has adopted a fundamental policy to
                                 offer each calendar quarter to repurchase a
                                 specified percentage (generally between 5% and
                                 25%) of the shares then outstanding at net
                                 asset value. Such repurchase offers are
                                 referred to as Tender Offers. Tender Offers are
                                 scheduled to occur on the 15th day (or the next
                                 business day if the 15th is not a business day)
                                 in the months of January, April, July and
                                 October. The Fund anticipates that its first
                                 Tender Offer will be in July, 2000. (See
                                 "Periodic Tender Offers.")

     The following tables are intended to assist investors in understanding the
various costs and expenses directly or indirectly associated with investing in
the Fund. Because the Fund does not yet have any operating history, this
information is based on estimated fees, expenses and net assets for the fiscal
year ending December 31, 2000.

(1) Colonial Management Associates, Inc. has contractually undertaken to waive
    its management fees and/or reimburse the Fund for its operating expenses to
    the extent that such expenses exceed 0.65% for Class Z shares through
    December 31, 2000. In addition, Colonial Management Associates, Inc. has
    undertaken to waive its management fee and/or reimburse the Fund for its
    operating expenses to the extent such expenses exceed the annual rate of
    .40% through April 30, 2000. Any such reimbursement will lower the class's
    overall expense ratio and increase its overall return to investors.



EXAMPLE.  This Example helps you compare the cost of investing in the Fund to
the cost of investing in other mutual funds. The Example assumes that (i) you
invest $1,000 in the Fund, (ii) your investment has a 5% return each year, (iii)
operating expenses remain the same, (iv) all income dividends and capital gains
distributions are reinvested in additional shares, and (v) expense
reimbursements are in effect for the first year in the periods below:

                                    THE FUND



     The Fund is a closed-end, diversified management investment company. The
Fund's primary investment objective is to provide high current income. The
Fund's secondary investment objective is to seek total return. No assurance can
be given that the Fund's investment objectives will be achieved. The Fund was
organized as a Massachusetts business trust under the laws of the Commonwealth
of Massachusetts on November 16, 1999, and is registered under the Investment
Company Act of 1940. The Fund's principal office is located at One Financial
Center, Boston, Massachusetts 02111, and its telephone number is 800-422-3737.


                                USE OF PROCEEDS


     The net proceeds from the sale of the shares offered hereby will be
invested in accordance with the Fund's investment objectives and policies. It is
presently anticipated that the Fund will be able to invest substantially all of
the net proceeds in securities that meet the Fund's investment objectives at or
shortly after it commences operations. To the extent that all of the proceeds
cannot be so invested, pending such investment, the Fund will invest such
proceeds initially in high-quality, short-term money market securities.



                     OTHER INVESTMENT STRATEGIES AND RISKS



USE OF LEVERAGE AND RELATED RISKS



     The Fund's use of reverse repurchase agreements, short-sales and other
derivative instruments to leverage its portfolio creates special risks not
associated with unleveraged funds having similar investment


                                        5
<PAGE>   29


objectives and policies, including a higher volatility of the net asset value of
the shares and potentially more volatility in the market value of the shares.
Any investment income or gains earned by the Fund on amounts effectively
borrowed that is in excess of what the Fund effectively pays as interest will
cause the value of and dividends, if any, on the Fund's shares to rise more
quickly than would otherwise be the case. Conversely, if the investment
performance by the Fund on leverage fails to cover the interest on such
leverage, the value of the shares may decrease more quickly than would otherwise
be the case and dividends thereon will be reduced or eliminated. This is the
speculative effect of "leverage."



     If the Fund's current investment income were not sufficient to meet
interest payments on the leverage, it could be necessary for the Fund to
liquidate certain of its investments, thereby reducing the net asset value
attributable to the shares. In addition, a decline in the net asset value of the
Fund's investments may affect the ability of the Fund to make dividend payments
on its shares and such failure to pay dividends or make distributions may result
in the Fund ceasing to qualify as a regulated investment company under the
Internal Revenue Code of 1986, as amended ("the Code").



     Successful use of a leveraging strategy may depend on the Advisor's ability
to correctly predict interest rates and market movements, and there is no
assurance that a leveraging strategy will be successful during any period in
which it is employed.


HEDGING STRATEGIES


     The Fund may enter into a number of hedging strategies, including futures
and options, to gain or reduce exposure to particular securities or markets.
These strategies, which are commonly referred to as derivatives, involve the use
of financial instruments whose value derives from the future, not current,
performance of an underlying security, index or currency. The Fund will use
these strategies for hedging purposes (attempting to offset a potential loss in
one position by establishing an interest in an opposite position) in connection
with the Fund's bond holdings or to adjust the duration of the Fund's bond
holdings. Hedging strategies involve the risk that they may exaggerate a loss,
potentially losing more money than the actual cost of the security, or limit a
potential gain. Also, with some hedging strategies there is the risk that the
other party to the transaction may fail to honor its contract terms, causing a
loss to the Fund.


WHEN-ISSUED SECURITIES, FORWARD COMMITMENTS AND DOLLAR ROLLS


     When-issued securities and forward commitments are securities which are
purchased prior to the date they are actually issued or delivered. These
securities involve the risk that they may fall in value by the time they are
actually issued or that the other party may fail to honor the contract terms. In
a dollar roll, the Fund sells a mortgage-backed security and simultaneously
enters into a commitment to purchase a similar security at a later date.


SHORT SALES


     A short sale is effected by selling a security that the Fund does not own,
or, if the Fund does own such security, it is not to be delivered upon
consummation of the sale. A short sale is "against the box" to the extent that
the Fund contemporaneously owns or has the right to obtain securities identical
to those sold short without payment. If the price of the security sold short
increases between the time of the short sale and the time the Fund replaces the
borrowed security, the Fund will incur a loss; conversely, if the price
declines, the Fund will realize a gain. Because the Fund's loss on a short sale
arises from increases in the value of the security sold short, such loss, like
the price of the security sold short, is theoretically unlimited.


REVERSE REPURCHASE AGREEMENTS


     The Fund may enter into reverse repurchase agreements by selling securities
and simultaneously agreeing to buy them back at a later date at a price equal to
the price paid to the Fund, together with an amount representing interest on
such amounts. Reverse repurchase agreements involve the risk that the

                                        6
<PAGE>   30


market value of the securities sold by the Fund may decline below the repurchase
price of the securities and, if the proceeds from the reverse repurchase
agreement are invested in securities, that the value of the securities bought
may decline at the same time there is a decline in the securities sold (and
required to be repurchased).


ZERO COUPON BONDS


     The Fund may invest in zero coupon bonds. Zero coupon bonds are issued at
less than their face value and do not make any payments of interest. As a
result, these bonds include greater credit risk and are subject to greater
volatility than bonds that pay cash interest on a current basis.


TEMPORARY DEFENSIVE STRATEGIES


     The Advisor may determine that adverse market conditions make it desirable
to temporarily suspend the Fund's normal investment activities. During such
times, the Fund may invest in cash, high-quality, short-term debt securities, or
any other securities without limit. Taking a temporary defensive position may
prevent the Fund from achieving its goals.



     In seeking to achieve its goals, the Fund may invest in various types of
securities and engage in various investment techniques which are not the
principal focus of the Fund and therefore are not described in this prospectus.
These types of securities and investment practices are identified and discussed
in the SAI, which you may obtain by contacting the Distributor at
1-800-422-3737.



                             MANAGEMENT OF THE FUND


TRUSTEES AND OFFICERS


     The Board of Trustees is responsible for the general supervision of the
Fund, including general supervision of the duties performed by the Advisor under
its Management Agreement with the Fund. There are twelve Trustees of the Fund,
one of whom is an "interested person" (as defined in the Investment Company Act
of 1940) of the Fund, the Advisor or the Distributor. The names and addresses of
the trustees and officers of the Fund and their principal occupations and other
affiliations during the past five years are set forth under "Management of the
Fund" in the Statement of Additional Information.


THE ADVISOR


     The Advisor is Colonial Management Associates, Inc., a Massachusetts

MANAGEMENT AGREEMENT


     The Management Agreement between the Advisor and the Fund (the "Management
Agreement") provides that, subject to the direction of the Board of Trustees of
the Fund and the applicable provisions of the Investment Company Act of 1940,
the Advisor is responsible for the actual management of the Fund's portfolio.
The responsibility for making decisions to buy, sell or hold a particular
investment rests with the Advisor, subject to review by the Board of Trustees of
the Fund and compliance with the applicable provisions of the Investment Company
Act of 1940 (the "1940 Act").



     The Advisor provides the Fund with accounting, bookkeeping and pricing
services and other services and office facilities (the expenses of which are
borne by the Fund as specified below), except to the extent these services are
provided by an administrator or an accounting firm hired by the Fund.



     Under the Management Agreement with the Fund, the Advisor receives a
monthly advisory fee at the annual rate of 0.50% of the average weekly net
assets of the Fund, including amounts borrowed from banks for investment
purposes. There are no current plans to utilize leverage through bank
borrowings. The Fund will not borrow from banks unless the Fund's Board of
Trustees approves the terms of the borrowing.



     The Advisor places all orders for the purchase and sale of portfolio
securities. In selecting broker-dealers, the Advisor may consider research and
brokerage services furnished by such broker-dealers to the Advisor and its
affiliates. In recognition of the research and brokerage services provided, the
Advisor may cause the Fund to pay the selected broker-dealer a higher commission
than would have been charged by another broker-dealer not providing such
services. Subject to seeking best execution, the Advisor may consider sales of
shares of certain funds distributed by affiliates of the Advisor in selecting
broker-dealers for portfolio security transactions.



     In addition to the fee of the Advisor, the Fund pays all other costs and
expenses of its operations, including compensation of its trustees (other than
those affiliated with the Advisor), custodian, transfer and dividend disbursing
expenses, legal fees, expenses of independent auditors, expenses of repurchasing
shares, shareholder reports, expenses of preparing, printing and distributing
notices, proxy statements and reports to governmental agencies, and taxes, if
any.


                        DETERMINATION OF NET ASSET VALUE


     The net asset value of the Fund's shares will be determined as of the close
of regular trading on the NYSE (generally 4:00 p.m. Eastern time). The net asset
value of the Fund equals the value of the Fund's assets less the Fund's
liabilities divided by the total number of outstanding shares. Portfolio
securities for which market quotations are readily available are valued at
current market value. Short-term investments maturing in 60 days or less are
valued at amortized cost when the Advisor determines, pursuant to procedures
adopted by the Board of Trustees, that such cost approximates current market
value. All other securities and assets are valued at their fair value following
procedures adopted by the Board of Trustees.



     In determining the value of securities for which market quotations are not
readily available, the Fund's custodian utilizes the valuations furnished by a
pricing service approved by the Board of Trustees. The pricing service uses
methods which include consideration of the following: yields or prices of
securities of comparable quality, type of issue, coupon, maturity and rating;
indications as to value from dealers; and general market conditions. The pricing
service may employ electronic data processing techniques or a matrix system, or
both, to determine valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Trustees.


                                        8
<PAGE>   32


     The Fund translates prices for its investments quoted in foreign currencies
into U.S. dollars at current exchange rates. As a result, changes in the value
of those currencies in relation to the U.S. dollar may affect the Fund's net
asset value. If events materially affecting the values of the Fund's foreign
investments occur between the close of foreign markets and the close of regular
trading on the NYSE, these investments may be valued at their fair value.


                     ORGANIZATION AND DESCRIPTION OF SHARES


     The Fund is a Massachusetts business trust organized under an Agreement and
Declaration of Trust ("Declaration of Trust") dated November 16, 1999, as
amended, which provides that each shareholder shall be deemed to have agreed to
be bound by the terms thereof. The Declaration of Trust may be amended by a vote
of either the Fund's shareholders or its Trustees. The Fund offers four classes
of shares: Class A, Class B, Class C and Class Z.



     Under Massachusetts law, shareholders of a Massachusetts business trust
such as the Fund could, in some circumstances, be held personally liable for
unsatisfied obligations of the Fund. However, the Declaration of Trust provides
that persons extending credit to, contracting with, or having any claim against
the Fund shall look only to its assets for payment under such credit, contract
or claim, and that the shareholders, Trustees and officers of the Fund shall
have no personal liability therefor. The Declaration of Trust requires that
notice of such disclaimer of liability be given in each contract, instrument or
undertaking executed or made on behalf of the Fund. Further, the Declaration of
Trust provides for indemnification of any shareholder against any loss and
expense arising from personal liability solely by reason of being or having been
a shareholder. Thus, the risk of a shareholder incurring financial loss on
account of shareholder liability is believed to be remote, because it would be
limited to circumstances in which the disclaimer was inoperative and the Fund
was unable to meet its obligations.



     The shares are not, and are not expected to be, listed for trading on any
national securities exchange nor, to the Fund's knowledge, is there, or is there
expected to be, any secondary trading market in the shares.



     Status of Shares.  The Fund is authorized to issue an unlimited number of
shares. The Board of Trustees may classify or reclassify any issued or unissued
shares of the Fund into shares of any class by redesignating such shares or by
setting or changing in any one or more respects, from time to time, prior to the
issuance of such shares, the preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications, or terms or
conditions or repurchase of such shares. Any such classification or
reclassification will comply with the provisions of the 1940 Act. As of January
14, 2000, the following shares of the Fund were outstanding:

<PAGE>   34


     The Fund reserves the right to change the investment minimums. The Fund
also reserves the right to refuse a purchase order for any reason, including if
it believes that doing so would be in the best interest of the Fund and its
shareholders.



                            MULTIPLE PRICING SYSTEM



     CHOOSING A SHARE CLASS.  The Fund offers one class of shares in this
prospectus -- Class Z shares, which are available to certain institutional and
other investors at net asset value without a sales charge or early withdrawal
charge. The Fund also offers Classes A, B and C shares through a separate
prospectus.



     HOW TO EXCHANGE SHARES.  Shareholders of the Fund whose shares are
repurchased during a Tender Offer may exchange those shares for shares of the
same class of a fund distributed by the Distributor at net asset value. Fund
shareholders will not be able to participate in this exchange privilege at any
time other than in connection with a Tender Offer. If your shares are subject to
an EWC, you will not be charged an EWC upon the exchange. However, when you sell
the shares acquired through the exchange, the shares sold may be subject to a
CDSC (a CDSC is the deferred sales charge applicable to the open-end funds) or
EWC, depending upon when you originally purchased the shares you exchanged. For
purposes of computing the CDSC or EWC, the length of time you have owned your
shares will be computed from the date of your original purchase and the
applicable CDSC or EWC will be the EWC of the Fund or, for Fund shares purchased
by exchange, the original Liberty fund.



     Unless your account is part of a tax-deferred retirement plan, an exchange
is a taxable event. Therefore, you may realize a gain or a loss for tax
purposes. The Fund may terminate your exchange privilege if the Advisor
determines that your exchange activity is likely to adversely impact its ability
to manage the Fund.


                             PERIODIC TENDER OFFERS


     The Board has adopted share repurchase policies as fundamental policies.
Those policies, which may not be changed without the vote of the holders of a
majority of the Fund's outstanding voting securities, provide that each calendar
quarter, the Fund will make a Tender Offer to repurchase a portion of the
outstanding shares from shareholders who request repurchase.



     REPURCHASE PROCEDURE.  At the beginning of each Tender Offer, shareholders
will be notified in writing about the Tender Offer, how they may request that
the Fund repurchase their shares and the deadline for shareholders to provide
their repurchase requests to the Distributor (the "Repurchase Request
Deadline"), which is the date the Tender Offer ends. The time between the
notification of the shareholders and the Repurchase Request Deadline may vary
from no more than six weeks to no less than three weeks. For each Tender Offer,
it is anticipated that each Repurchase Request Deadline will be on the 15th day
in each of the months of January, April, July and October, or, if the 15th day
is not a business day, the next business day. The repurchase price of the shares
will be the net asset value as of the close of regular trading on the NYSE on
the date on which the repurchase price of shares will be determined (the
"Repurchase Pricing Date"). It is anticipated that normally the Repurchase
Pricing Date will be the same date as the Repurchase Request Deadline, and if
so, the Repurchase Request Deadline will be set for a time no later than the
close of regular trading on the NYSE on such date. The Fund has determined that
the Repurchase Pricing Date may occur no later than the 14th day after the
Repurchase Request Deadline or the next business day if the 14th day is not a
business day.


     The Board may establish other policies for repurchases of shares that are
consistent with the 1940 Act and other pertinent laws. Shares tendered by
shareholders by any Repurchase Request Deadline will be repurchased subject to
the aggregate repurchase amounts established for that Repurchase Request
Deadline. Repurchase proceeds will be paid to shareholders in cash within seven
days after each Repurchase Pricing Date. The end of the seven days is referred
to as the "Repurchase Payment Deadline."

                                       11
<PAGE>   35


     Repurchase offers and the need to fund repurchase obligations may affect
the ability of the Fund to be fully invested, which may reduce returns.
Moreover, diminution in the size of the Fund through repurchases without
offsetting new sales may result in untimely sales of portfolio securities and a
higher expense ratio, and may limit the ability of the Fund to participate in
new investment opportunities. The Fund may borrow to meet repurchase
obligations, which entails certain risks and costs. The Fund may also sell
portfolio securities to meet repurchase obligations which, in certain
circumstances, may adversely affect the market for portfolio securities and
reduce the Fund's value.



     REPURCHASE AMOUNTS.  The Board, in its sole discretion, will determine the
number of shares that the Fund will offer to repurchase (the "Tender Offer
Amount") for a given Repurchase Request Deadline. However, the Tender Offer
Amount will generally be at least 5% and no more than 25% of the total number of
shares outstanding on the Repurchase Request Deadline.



     If shareholders tender more than the Tender Offer Amount for a given Tender
Offer, the Fund may repurchase an additional amount of shares of up to 2% of the
shares outstanding on the Repurchase Request Deadline. If the Fund determines
not to repurchase more than the Tender Offer Amount, or if the Fund determines
to repurchase the additional 2% of the shares outstanding, but Fund shareholders
tender shares in excess of that amount, the Fund will repurchase the shares on a
pro rata basis and shareholders would be unable to sell in the Tender Offer all
or a portion of their shares tendered. The Fund may, however, accept all shares
tendered by shareholders who own less than 100 shares and who tender all their
shares, before accepting on a pro rata basis shares tendered by other
shareholders.



     NOTICES TO SHAREHOLDERS.  Notice of each quarterly Tender Offer (and any
additional discretionary repurchase offers) will be given to each beneficial
owner of shares between 21 and 42 days before each Repurchase Request Deadline.
The notice will contain information shareholders should consider in deciding
whether or not to tender their shares. The notice will also include detailed
instructions on how to tender shares. The notice will state the Tender Offer
Amount. The notice will also identify the dates of the Repurchase Request
Deadline, scheduled Repurchase Pricing Date, and scheduled Repurchase Payment
Deadline. The notice will describe the risk of fluctuation in the net asset
value between the Repurchase Request Deadline and the Repurchase Pricing Date,
if such dates do not coincide, and the possibility that the Fund may use an
earlier Repurchase Pricing Date than the scheduled Repurchase Pricing Date under
certain circumstances (if the scheduled Repurchase Pricing Date is not the
Repurchase Request Deadline). The notice will describe (i) the procedures for
shareholders to tender their shares, (ii) the procedures for the Fund to
repurchase shares on a pro rata basis, (iii) the circumstances in which the Fund
may suspend or postpone a Tender Offer, and (iv) the procedures that will enable
shareholders to withdraw or modify their tenders of shares until the Repurchase
Request Deadline. The notice will set forth the net asset value of the shares to
be repurchased no more than seven days before the date of notification, and how
shareholders may ascertain the net asset value after the notification date.


     REPURCHASE PRICE.  The notice of the Tender Offer will also provide
information concerning the net asset value per share, such as the net asset
value as of a recent date or a sampling of recent net asset values, and a
toll-free number for information regarding the Tender Offer.


     SUSPENSION OR POSTPONEMENT OF REPURCHASE OFFER.  The Fund may, with the
approval of a majority of the Trustees who are not "interested persons" (as
defined in the 1940 Act) of the Fund suspend or postpone a repurchase offer
only: (A) if making or effecting the repurchase offer would cause the Fund to
lose its status as a regulated investment company under the Internal Revenue
Code; (B) for any period during which the NYSE or any market on which the
securities owned by the Fund are principally traded is closed, other than
customary weekend and holiday closings, or during which trading in such market
is restricted; (C) for any period during which an emergency exists as a result
of which disposal by the Fund of securities owned by it is not reasonably
practicable, or during which it is not reasonably practicable for the Fund
fairly to determine the value of its net assets; or (D) for such other periods
as the Securities and Exchange Commission may by order permit for the protection
of shareholders of the Fund.



     LIQUIDITY REQUIREMENTS.  The Fund must maintain liquid assets equal to the
Tender Offer Amount from the time that the notice is sent to shareholders until
the Repurchase Pricing Date. The Fund will

                                       12
<PAGE>   36


ensure that a percentage of its net assets equal to at least 100% of the Tender
Offer Amount consists of assets (a) that can be sold or disposed of in the
ordinary course of business at approximately the price at which the Fund has
valued the investment within the time period between the Repurchase Request
Deadline and the Repurchase Payment Deadline; or (b) that mature by the
Repurchase Payment Deadline.



     The Board of Trustees has adopted procedures that are reasonably designed
to ensure that the Fund's assets are sufficiently liquid so that it can comply
with the Tender Offer and the liquidity requirements described in the previous
paragraph. If, at any time, the Fund falls out of compliance with these
liquidity requirements, the Board will take whatever action it deems appropriate
to ensure compliance.


                                  TAX MATTERS


     The following federal tax discussion reflects provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), existing Treasury regulations,
rulings published by the Internal Revenue Service, and other applicable
authority, as of the date of this Prospectus. These authorities are subject to
change by legislative or administrative action. The following discussion is only
a summary of some of the important federal tax considerations generally
applicable to investments in the Fund. There may be other tax considerations
applicable to particular investors. In addition, income earned through an
investment in the Fund may be subject to foreign, state and local taxes.
Prospective shareholders are therefore urged to consult their tax advisors with
respect to the tax consequences to them of an investment in the Fund. For more
information on federal income tax considerations, see "Tax Matters" in the
Statement of Additional Information.



FEDERAL TAXATION OF THE FUND



     The Fund intends to qualify each year for taxation as a regulated
investment company under Subchapter M of the Code. If the Fund so qualifies, the
Fund will not be subject to federal income tax on income distributed in a timely
manner to Fund shareholders in the form of dividends or capital gain
distributions. The Fund intends to distribute all its net investment income and
all its net capital gains to shareholders at least annually. If the Fund is
determined not to have distributed all of its net investment income, it could
owe tax at the corporate level, and, in certain circumstances, lose its
eligibility to be treated as a regulated investment company. For more
information on the requirements the Fund must satisfy in order to qualify as a
regulated investment company, see "Tax Matters -- Federal Taxation of the Fund"
in the Statement of Additional Information.



     The Fund's investments and hedging activities are subject to special
federal tax rules. Federal rules governing the Fund's hedging transactions
(including hedging transactions in futures and options) may alter the character
of distributions to shareholders. The Fund's investments in securities issued at
a discount will (and investments in securities purchased at a discount may)
require the Fund to accrue and distribute income not yet received. Therefore, in
order to generate sufficient cash to make the requisite distributions, the Fund
may be required to sell securities in its portfolio that it otherwise would have
continued to hold.


FEDERAL TAXATION OF SHAREHOLDERS


     DIVIDENDS AND OTHER DISTRIBUTIONS.  Distributions of net investment income
(including the excess, if any, of net short-term capital gain over net long-term
capital loss), will be taxable to shareholders as ordinary income, and will not
qualify for the corporate dividends-received reduction. Distributions of net
capital gain will be taxable to shareholders as long-term capital gain
(generally, at a 20% rate for noncorporate shareholders), without regard to how
long a shareholder has held shares of the Fund, and will not qualify for the
corporate dividends-received deduction.



     Distributions of income and capital gains are taxable whether received in
cash or reinvested in additional shares. If a dividend or distribution is made
shortly after a shareholder purchases shares of the


                                       13
<PAGE>   37


Fund, while in effect a return of capital to the shareholder, the dividend or
distribution is taxable, as described above. This is called "buying a dividend"
and should be avoided, if possible.



     The Fund's net investment income calculated for accounting purposes and
distributed to shareholders may in certain circumstances exceed or be less than
the Fund's net tax-exempt and taxable income for federal tax purposes. If the
Fund distributes amounts in excess of the Fund's "earnings and profits" (which
provides the measure of the Fund's dividend-paying capacity for tax purposes),
such distributions to shareholders will be treated as a return of capital to the
extent of a shareholder's basis in his or her shares, and thereafter as gain
from the sale or exchange of a capital asset. A return of capital is not taxable
to a shareholder and has the effect of reducing a shareholder's basis in the
relevant shares, which basis reduction would cause shareholders to realize gain
if their shares were sold for an amount equal to the purchase price.



     Any dividend paid by the Fund during January of a given year generally is
deemed to have been received by shareholders on December 31 of the preceding
year, provided that the dividend actually was declared by the Fund in October,
November or December of such preceding year and payable to shareholders of
record on a date in such a month.



     The Fund will notify shareholders each year of the amount and tax status of
dividends and other distributions, including the amount of any distribution of
net capital gain.



     SALE OR REDEMPTION OF SHARES.  In some circumstances, the sale or exchange
of shares in the Fund may give rise to gain or loss. In general, any gain or
loss realized upon a taxable disposition of shares in the Fund by a shareholder
will be treated as long-term capital gain or loss if the shares have been held
for more than twelve months, and otherwise as short-term capital gain or loss.
However, if a shareholder buys shares in the Fund and sells them at a loss
within six months, any loss will be disallowed for federal income tax purposes
to the extent of any exempt-interest dividends received on such shares. In
addition, any loss (not already disallowed as provided in the preceding
sentence) realized upon a taxable disposition of shares in the Fund held for six
months or less will be treated as long-term, rather than short-term, capital
loss to the extent of any net capital gain distributions received by the
shareholder with respect to those shares. All or a portion of any loss realized
upon a taxable disposition of shares in the Fund will be disallowed if other
shares in the Fund are purchased within 30 days before or after the disposition.
In such a case, the basis of the newly purchased shares in the Fund will be
adjusted to reflect the disallowed loss.



     Gain or loss, if any, resulting from a redemption of shares in the Fund
generally will be treated as gain or loss from the sale or exchange of a capital
asset under Section 302 of the Code, rather than as a dividend, but only if the
redemption distribution (i) is deemed not to be essentially equivalent to a
dividend, (ii) is in complete redemption of an owner's interest in the Fund,
(iii) is substantially disproportionate with respect to the owner, or (iv) with
respect to non-corporate owners, is in partial liquidation of the Fund.



       CUSTODIAN, TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR



     The Fund's securities and cash are held by The Chase Manhattan Bank, whose
principal business address is 270 Park Avenue, New York, New York 10017-2070, as
custodian under a custodian contract.



     Liberty Funds Services, Inc., P.O. Box 1722, Boston, Massachusetts 02105, a
wholly-owned subsidiary of LFG, is the agent of the Fund for the transfer of
shares, disbursement of dividends and maintenance of shareholder account
records.


                            REPORTS TO SHAREHOLDERS


     The Fund will send unaudited semiannual and audited annual reports to its
shareholders, including, as currently required by regulations of the Securities
and Exchange Commission (the "SEC"), a list of investments held.

                       INVESTMENT OBJECTIVES AND POLICIES

      The Fund's Prospectus describes its investment objectives and investment
policies. This SAI includes additional information concerning, among other
things, the investment policies of the Fund and information about certain
securities and investment techniques that are described or referred to in the
Prospectus or in which the Fund expects to engage. Except as indicated under
"Fundamental Investment Policies," the Fund's investment policies are not
fundamental and the Trustees may change the policies without shareholder
approval.

FUNDAMENTAL INVESTMENT POLICIES

      The following fundamental restrictions are for the protection of the
Fund's shareholders and cannot be changed without the approval of the holders
of a "majority of the outstanding" shares, voting together as a single class. A
"majority of the outstanding" shares means the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented or (ii) more than 50% of the outstanding shares, as defined in the
Investment Company Act of 1940, as amended (the "1940 Act").

      The Fund may:

      1.    issue senior securities or borrow money to the extent permitted by
            the 1940 Act;

      2.    only own real estate acquired as a result of owning securities;

      3.    purchase and sell futures contracts and related options;

      4.    underwrite securities issued by others only when disposing of
            portfolio securities;

      5.    make loans through lending of securities, through the purchase of
            debt instruments or similar evidences of indebtedness typically sold
            to financial institutions and through repurchase agreements;


      6.    not concentrate more than 25% of its total assets in any one
            industry, or with respect to 75% of total assets purchase any
            security (other than obligations of the U.S. Government and cash
            items including receivables) if as a result more than 5% of its
            total assets would then be invested in securities of a single
            issuer or purchase the voting securities of an issuer if, as a
            result of such purchase, the Fund would own more than 10% of the
            outstanding voting shares of such issuer  (The Fund will treat
            each state and each separate political subdivision, agency,
            authority or instrumentality of such state, each multi-state agency
            or authority, and each guarantor, if any, as separate issuers.  In
            the utilities category, gas, electric, water and telephone
            companies will be considered as separate industries.); and


      7.    not purchase or sell commodities or commodities contracts, except
            that, consistent with its investment policies, the Fund may
            purchase and sell financial futures contracts and options and may
            enter into swap agreements, foreign exchange contracts and other
            financial transactions not requiring the delivery of physical
            commodities.

      The restrictions and other limitations set forth above will apply only at
the time of purchase of securities and will not be considered violated unless an
excess or deficiency occurs or exists immediately after and as a result of an
acquisition of securities.



                                      B-2

OTHER INVESTMENT POLICIES

      As non-fundamental investment policies which may be changed by the Fund
without a shareholder vote, the Fund may not:

      1. purchase securities on margin, but it may receive short-term credit to
         clear securities transactions and may make initial or maintenance
         margin deposits in connection with futures transactions; and

      2. invest in interests in oil, gas or other mineral exploration or
         development programs, including leases.



                          FUND CHARGES AND EXPENSES


     Under the Fund's Management Agreement with the Advisor, the Fund pays the
Advisor a monthly fee based on the average weekly net assets of the Fund,
including the proceeds of bank borrowings for investment purposes, if any, for
such month at the annual rate of 0.50% of average weekly net assets.






                         TENDER OFFER FUNDAMENTAL POLICY

      The Board has adopted a resolution setting forth the Fund's fundamental
policy that it will conduct quarterly Tender Offers (the "Tender Offer
Fundamental Policy").

      The Tender Offer Fundamental Policy sets the interval between each
Repurchase Offer at one quarter and provides that the Fund shall conduct a
Tender Offer each quarter (unless suspended or postponed in accordance with
regulatory requirements). The Repurchase Request Deadline will be established by
the Fund and will be based on factors such as market conditions, liquidity of
the Fund's assets and shareholder servicing conditions. The Tender Offer
Fundamental Policy also provides that the repurchase pricing shall occur not
later than fourteenth day after the Repurchase Request Deadline or the next
business day if the fourteenth day is not a business day.

      The Tender Offer Fundamental Policy may be changed only by a majority vote
of the outstanding voting securities. For more information, please refer to the
Prospectus under the caption "Periodic Tender Offers."

Investment Company Act of 1940, as amended (the "1940 Act")) of the Fund or

of $8,000 for each regular joint meeting and $1,000 for each special joint
meeting. Committee chairs and the lead Trustee receive an annual retainer of
$1,000 and Committee chairs receive $1,000 for each special meeting attended on
a day other than a regular joint meeting day. Committee members receive an

INVESTMENT ADVISOR


      Colonial Management Associates, Inc. (the "Advisor") has rendered
investment advisory services to investment company, institutional and other
clients since 1931. The Advisor currently serves as investment advisor,
sub-advisor or administrator for 38 open-end and 8 closed-end management
investment company portfolios. Trustees and officers of the Fund, who are also
officers of the Advisor or its affiliates, will benefit from the advisory fees,
sales commissions and agency fees paid or allowed by the Fund. More than 30,000
financial advisors have recommended the fund to over 800,000 clients worldwide,
representing more than $15 billion in assets.

      The Advisor is a subsidiary of Liberty Funds Group LLC ("LFG"). One
Financial Center, Boston, MA 02111. LFG is an indirect wholly-owned subsidiary
of Liberty Financial Companies, Inc. ("Liberty Financial"), which in turn is a

turn is a direct wholly-owned subsidiary of Liberty Mutual Equity Corporation,
which in turn is a direct wholly-owned subsidiary of Liberty Mutual Insurance
Company ("Liberty Mutual"). Liberty Mutual is an underwriter of workers'
compensation insurance and a property and casualty insurer in the United States.
Liberty Financial's address is 600 Atlantic Avenue, Boston, Ma 02210. Liberty
Mutual's address is 175 Berkeley Street, Boston, MA 02117.


      Under a Management Agreement (the "Agreement"), the Advisor has contracted
to furnish the Fund with investment research and recommendations or fund
management, respectively, and accounting and administrative personnel and
services, and with office space, equipment and other facilities. For these
services and facilities, the Fund pays a monthly fee based on the average
weekly net assets of the Fund for such month. Under the Agreement, any
liability of the Advisor to the Fund and/or its shareholders is limited to
situations involving the Advisor's own willful misfeasance, bad faith, gross
negligence or reckless disregard of its duties.

      The Agreement may be terminated with respect to the Fund at any time on
60 days' written notice by the Advisor or by the Trustees of the Fund or by a
vote of a majority of the outstanding voting securities of the Fund. The
Agreement will automatically terminate upon any assignment thereof and shall
continue in effect from year to year only so long a such continuance is approved
at least annually (i) by the Trustees of the Fund or by a vote of a majority of
the outstanding voting securities of the Fund and (ii) by vote of a majority of
the Trustees who are not interested persons (as such term is defined in the 1940
Act) of the Advisor of the Fund, cast in person at a meeting called for the
purpose of voting on such approval.

      The Advisor pays all salaries of officers of the Fund. The Fund pays all
expenses not assumed by the Advisor, including, but not limited to, auditing,
legal, custodial, investor servicing and shareholder reporting expenses. The
Fund pays the cost of printing and mailing any Prospectuses sent to
shareholders.


      The Advisor also provides the Fund with bookkeeping and pricing services,
and for these services, the Fund pays the Advisor a monthly fee of $25,000 plus
 .0025 of 1% of average net assets over $50 million.

DISTRIBUTOR

      Shares of the Fund are distributed by Liberty Funds Distributor, Inc.
("Distributor"), One Financial Center, Boston, MA 02111, under a Distribution
Agreement (the "Agreement"). The Distributor is a subsidiary of the Advisor,
which is an indirect subsidiary of LFG. The Agreement continues in effect from
year to year, provided such continuance is approved annually (1) by a majority
of the Board or by a majority of the outstanding voting securities of the Fund,
and (2) by a majority of the trustees who are not parties to the Agreement or
interested persons of any such party. The Fund has agreed to pay all expenses
in connection with registration of its shares with the Securities and Exchange
Commission and auditing and filing fees in connection with registration of its
shares under the various state blue sky laws and assumes the cost of preparation
of the prospectus and other expenses.

DISTRIBUTION AND SERVICE FEES. In addition to an early withdrawal charge, each
of Class A, B, and C of shares is authorized under a distribution plan ("Plan")
to use the assets attributable to a class to finance certain activities relating
to the distribution of shares to investors. These include marketing and other
activities to support the distribution of the Class A, B, and C shares and the
services provided to you by your financial advisor. The Plan was approved and
reviewed in a manner consistent with Rule 12b-1 under the 1940 Act, which
regulates the manner in which an open-end investment company may directly or
indirectly bear the expenses of distributing its shares. Although the Fund is
not an open-end investment company, it has undertaken to comply with the terms
of Rule 12b-1 as a condition of an exemptive order under the 1940 Act to permit
it to have a multi-class structure, early withdrawal charges, and distribution
fees.

      Under the Plan, distribution and service fees paid by the Fund to the
Distributor may equal up to an annual rate of 0.25% of average daily net assets
attributable to Class A shares, 0.70% of average daily net assets attributable
to Class B shares, and 0.85% of average daily net assets attributable to Class C
shares, respectively. Since the distribution and service fees are payable
regardless of the Distributor's expenses, the Distributor may realize a profit
from the fees. The Plan authorizes any other payments by the Fund to the
Distributor and its affiliates to the extent that such payments might be
construed to be indirect financing of the distribution of Fund shares.

      The Trustees believe that the Plan could be a significant factor in the
growth and retention of Fund assets resulting in a more advantageous expense
ratio and increased flexibility which could benefit each class of Fund
shareholders. The Plan will continue in effect from year to year so long as
continuance is specifically approved at least annually by a vote of the
trustees, including the trustees who are not interested persons of the Fund and
who have no direct or indirect financial interest in the operation of the Plan
or in any agreements related to the Plan ("Independent Trustees"), cast in
person at a meeting called for the purpose of voting on the Plan. The Plan may
not be amended to increase the fee materially without approval by a vote of a
majority of the outstanding voting securities of the relevant class of shares
and all material amendments of the Plan must be approved by the trustees in the
manner provided in the foregoing sentence. The Plan may be terminated at any
time by a vote of a majority of the Independent Trustees or by a vote of a
majority of the outstanding voting securities of the relevant class of shares.
The continuance of the Plan will only be effective if the selection and
nomination of the Independent Trustees is effected by such Independent Trustees.

      EARLY WITHDRAWAL CHARGES (EWCs). Certain investments in Class A, B and C
shares are subject to an EWC. You will pay the EWC only on shares you submit for
repurchase within a certain amount of time after purchase. The EWC generally
declines each year until there is no charge for repurchased shares. The EWC is
applied to the net asset value at the time of purchase or repurchase, whichever
is lower. For purposes of calculating the EWC, the start of the holding period
is the first day of the month following each purchase, shares you purchase with
reinvested dividends or capital gains are not subject to an EWC. When shares are
repurchased, the Fund will automatically repurchase those shares not subject to
an EWC and then those you have held the longest. This policy helps reduce and
possibly eliminate the potential impact of the EWC. In certain circumstances,
EWCs may be waived, as described in this Statement of Additional Information.

      CONVERSION FEATURE. Class B shares will automatically convert to Class A
shares after eight years and after that date, Class B shares will no longer be
subject to the distribution fees applicable to Class B shares. Conversion will
be on the basis of the relative net asset values per share, without the
imposition of any sales charge, fee or other charge. The purpose of the
conversion feature is to relieve the holders of Class B shares from asset-based
distribution expenses applicable to such shares at such time as the Class B
shares have been outstanding long enough for the Distributor to have been
substantially compensated for distribution-related expenses incurred in
connection with those shares. Class C shares do not convert to Class A shares.
Therefore, holders of Class C shares will continue to bear the asset-based
distribution fees on the Class C shares for as long as they hold such shares.




                             PORTFOLIO TRANSACTIONS

      The Advisor is responsible for decisions to buy and sell securities and
other portfolio holdings for the Fund, the selection of brokers and dealers to
effect the transactions and the negotiation of brokerage commissions, if any.
Fixed-income securities are generally traded on a "net" basis with dealers
acting as principals for their own accounts without a stated commission,
although the price of the security will likely include a profit to the dealer.
In underwritten offerings, securities are usually purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.


      In placing orders for portfolio securities of the Fund, the Advisor is
required to give primary consideration to obtaining the most favorable price and
efficient execution. This means that the Advisor will seek to execute each
transaction at a price and commission, if any, which provides the most favorable
total cost or proceeds reasonably attainable under the circumstances. In seeking
the most favorable price and execution, the Advisor, having in mind the Fund's
best interest, will consider all factors it deems relevant, including, by way of
illustration, price, the size of the transaction, the nature of the market for
the security, the amount of commission, the timing of the transaction taking
into account market prices and trends, the reputation, experience and financial
stability of the broker-dealer involved and the quality of service rendered by
the broker-dealer in other transactions. Though the Advisor generally seeks
reasonably competitive spreads or commissions, the Fund will not necessarily be
paying the lowest spread or commission available. Within the framework of the
policy of obtaining the most favorable price and efficient execution, the
Advisor will consider research and investment services provided by brokers and
dealers who effect or are parties to portfolio transactions with the Fund, the
Advisor or the Advisor's other clients. Such research and investment services
are those which brokerage houses customarily provide to institutional investors
and include statistical and economic data and research reports on particular
issuers and industries. Such services are used by the Advisor in connection with
all of its investment activities, including managing other investment accounts.
Conversely, brokers furnishing such services may be selected for the execution
of transactions for such other accounts, and the services furnished by such
brokers may be used by the Advisor in providing investment management for the
Fund. Commission rates are established pursuant to negotiations based on the
quality and quantity of execution services provided by the broker or dealer in
light of generally prevailing rates. The management fee paid by the Fund will
not be reduced because the Advisor and/or other clients receive such services.
The allocation of orders and the commission rates paid by the Fund will be
reviewed periodically by the Board of Trustees.



      As permitted by Section 28(e) of the Securities Exchange Act of 1934, as
amended (the "1934 Act"), the Advisor may cause the Fund to pay a broker-dealer
which provides "brokerage and research services" (as defined in


                                      B-10

<PAGE>   49
the 1934 Act) to the Advisor, an amount of disclosed commission for effecting a
securities transaction for the Fund in excess of the commission which another
broker-dealer would have charged for effecting that transaction.


      The Fund recently commenced operations and has not paid any brokerage
commissions for the execution of portfolio transactions.



                              DESCRIPTION OF SHARES

      The descriptions of the shares contained in the Prospectus and this
Statement of Additional Information do not purport to be complete and are
subject to and qualified in their entireties by reference to the Declaration of
the Fund (the "Declaration") and the By-Laws of the Fund (the "By-Laws"), as
each from time to time is amended. Copies of the Declaration and the form of the
By-Laws are filed as exhibits to the Registration Statement of which the
Prospectus and this Statement of Additional Information are a part and may be
inspected, and copies thereof may be obtained, as described under "Table of
Contents Statement of Additional Information -- For More Information" in the
Prospectus.

      The Declaration authorizes the issuance of an unlimited number of shares
without par value. All shares have equal rights as to the payment of dividends
and the distribution of assets upon liquidation. Shares will, when issued, be
fully paid and, subject to matters discussed in "Shareholder Liability,"
non-assessable, and will have no pre-emptive or conversion rights or rights to
cumulative voting.

                               HOW TO BUY SHARES

The Prospectus contains a general description of how investors may buy shares of
the Fund and tables of charges. This SAI contains additional information which
may be of interest to investors.

The Fund will accept unconditional orders for shares to be executed at the
public offering price based on the net asset value ("NAV") per share next
determined after the order is placed in good order. The public offering price is
the NAV plus the applicable sales charge, if any. In the case of orders for
purchase of shares placed through Financial Service Firms (singularly, a "FSF"),
the public offering price will be determined on the day the order is placed in
good order, but only if the FSF receives the order prior to the time at which
shares are valued and transmits it to the Fund before the Fund processes that
day's transactions. If the FSF fails to transmit before the Fund processes that
day's transactions, the customer's entitlement to that day's closing price must
be settled between the customer and the FSF. If the FSF receives the order after
the time at which the Fund values its shares, the price will be based on the NAV
determined as of the close of the Exchange on the next day it is open. If funds
for the purchase of shares are sent directly to Liberty Financial Services, Inc.
("LFS"), they will be invested at the public offering price next determined
after receipt in good order. Payment for shares of the Fund must be in U.S.
dollars; if made by check, the check must be drawn on a U.S. bank.

The Fund receives the entire NAV of shares sold. For shares subject to an
initial sales charge, Liberty Financial Distributor, Inc.'s commission is
the sales charge shown in the Fund's Prospectus less any applicable FSF
discount. The FSF discount is the same for all FSFs, except that LFD retains the
entire sales charge on any sales made to a shareholder who does not specify a
FSF on the Investment Account Application ("Application"). Liberty Financial
Distributor, Inc. ("LFD") generally retains 100% of any asset-based sales charge
(distribution fee) or contingent deferred sales charge. Such charges generally
reimburse LFD for any up-front and/or ongoing commissions paid to FSFs.

Checks presented for the purchase of shares of the Fund which are returned by
the purchaser's bank or checkwriting privilege checks for which there are
insufficient funds in a shareholder's account to cover redemption will subject
such purchaser or shareholder to a $15 service fee for each check returned.
Checks must be drawn on a U.S. bank and must be payable in U.S. dollars.



                                      B-11

<PAGE>   50


LFS acts as the shareholder's agent whenever it receives instructions to carry
out a transaction on the shareholder's account. Upon receipt of instructions
that shares are to be purchased for a shareholder's account, the designated FSF
will receive the applicable sales commission. Shareholders may change FSFs at
any time by written notice to LFS, provided the new FSF has a sales agreement
with LFD.

Shares credited to an account are transferable upon written instructions in good
order to LFS and may be redeemed as described under "How to Sell Shares" in the
Prospectus. Certificates will not be issued for Class A shares unless
specifically requested and no certificates will be issued for Class B, C or Z
shares. Shareholders may send any certificates which have been previously
acquired to LFS for deposit to their account.

LFD may, at its expense, provide special sales incentives (such as cash payments
in addition to the commissions specified in the Fund's SAI) to FSFs that agree
to promote the sale of shares of the Fund or other funds that LFD distributes.
At its discretion, the Distributor may offer special sales incentives only to
selected FSFs or to FSFs who have previously sold or expect to sell significant
amounts of the Fund's shares.

                  SPECIAL PURCHASE PROGRAMS/INVESTOR SERVICES

The following special purchase programs/investor services may be changed or
eliminated at any time.

AUTOMATIC INVESTMENT PLANS. As a convenience to investors, shares of most funds
advised by Colonial, Newport Fund Management, Inc., Crabbe Huson Group, Inc. and
Stein Roe & Farnham Incorporated may be purchased through the Automatic
Investment Plans. Preauthorized monthly bank drafts or electronic funds
transfers for a fixed amount of at least $50 are used to purchase a Fund's
shares at the public offering price next determined after LFD receives the
proceeds from the draft (normally the 5th or the 20th of each month, or the next
business day thereafter). If your Automatic purchase is by electronic funds
transfer, you may request the Automatic purchase for any day. Further
information and application forms are available from FSFs or from LFD.

AUTOMATED DOLLAR COST AVERAGING (Classes A, B and C). The Automated Dollar Cost
Averaging program allows you to exchange $100 or more on a monthly basis from
any mutual fund advised by Colonial, Newport Fund Management, Inc., Crabbe Huson
Group, Inc. and Stein Roe & Farnham Incorporated in which you have a current
balance of at least $5,000 into the same class of shares of up to four other
funds. Complete the Automated Dollar Cost Averaging section of the Application.
The designated amount will be exchanged on the third Tuesday of each month.
There is no charge for exchanges made pursuant to the Automated Dollar Cost
Averaging program. Exchanges will continue so long as your fund balance is
sufficient to complete the transfers. Your normal rights and privileges as a
shareholder remain in full force and effect. Thus you can buy any fund, exchange
between the same Class of shares of funds by written instruction or by telephone
exchange if you have so elected and withdraw amounts from any fund, subject to
the imposition of any applicable CDSC.

Any additional payments or exchanges into your fund will extend the time of the
Automated Dollar Cost Averaging program.

An exchange is generally a capital sale transaction for federal income tax
purposes.

You may terminate your program, change the amount of the exchange (subject to
the $100 minimum), or change your selection of funds, by telephone or in
writing; if in writing by mailing your instructions to Liberty Funds Services,
Inc. P.O. Box 1722, Boston, MA 02105-1722.

You should consult your FSF or investment advisor to determine whether or not
the Automated Dollar Cost Averaging program is appropriate for you.

LFD offers several plans by which an investor may obtain reduced sales charges.
These plans may be altered or discontinued at any time. See "Programs For
Reducing or Eliminating Sales Charges" for more information.

TAX-SHELTERED RETIREMENT PLANS. LFD offers prototype tax-qualified plans,
including Individual Retirement Accounts (IRAs), and Pension and Profit-Sharing
Plans for individuals, corporations, employees and the self-employed. The
minimum initial Retirement Plan investment is $25. Investors Bank & Fund
Company is the Trustee of LFD prototype plans and charges a $15 annual fee.
Detailed information concerning these Retirement Plans and copies of the
Retirement Plans are available from LFD.

Participants in non-LFD prototype Retirement Plans (other than IRAs) also are
charged a $10 annual fee unless the plan maintains an omnibus account with LFS.
Participants in LFD prototype Plans (other than IRAs) who liquidate the total
value of their account will also be charged a $15 close-out processing fee
payable to LFS. The fee is in addition to any applicable CDSC. The fee will not
apply if the participant uses the proceeds to open a LFD IRA Rollover account in
any fund, or if the Plan maintains an omnibus account.

Consultation with a competent financial and tax advisor regarding these Plans
and consideration of the suitability of fund shares as an investment under the
Employee Retirement Income Security Act of 1974 or otherwise is recommended.

TELEPHONE ADDRESS CHANGE SERVICES. By calling LFS, shareholders or their FSF of
record may change an address on a recorded telephone line. Confirmations of
address change will be sent to both the old and the new addresses. Telephone
redemption privileges are suspended for 30 days after an address change is
effected.

CASH CONNECTION. Dividends and any other distributions may be automatically
deposited to a shareholder's bank account via electronic funds transfer.
Shareholders wishing to avail themselves of this electronic transfer procedure
should complete the appropriate sections of the Application.

AUTOMATIC DIVIDEND DIVERSIFICATION. The automatic dividend diversification
reinvestment program (ADD) generally allows shareholders to have all
distributions from a fund automatically invested in the same class of shares of
another fund. An ADD account must be in the same name as the shareholder's
existing open account with the particular fund.  Call LFS for more information
at 1-800-422-3737.

PROGRAMS FOR REDUCING OR ELIMINATING SALES CHARGES
RIGHT OF ACCUMULATION AND STATEMENT OF INTENT (Class A shares only) Reduced
sales charges on Class A shares can be effected by combining a current purchase
with prior purchases of Class A, B, C and Z shares of the funds distributed by
LFD. The applicable sales charge is based on the combined total of:


1.       the current purchase; and

2.       the value at the public offering price at the close of business on the
         previous day of all funds' Class A shares held by the shareholder
         (except shares of any money market fund, unless such shares were
         acquired by exchange from Class A shares of another fund other than a
         money market fund and Class B, C, and Z shares).



                                      B-13

<PAGE>   52


LFD must be promptly notified of each purchase which entitles a shareholder to a
reduced sales charge. Such reduced sales charge will be applied upon
confirmation of the shareholder's holdings by LFS. A fund may terminate or amend
this Right of Accumulation.

Any person may qualify for reduced sales charges on purchases of Class A shares
made within a thirteen-month period pursuant to a Statement of Intent
("Statement"). A shareholder may include, as an accumulation credit toward the
completion of such Statement, the value of all Class A, B, C and Z shares held
by the shareholder on the date of the Statement in funds distributed by LFD
(except shares of any money market fund, unless such shares were acquired by
exchange from Class A shares of another non-money market fund). The value is
determined at the public offering price on the date of the Statement. Purchases
made through reinvestment of distributions do not count toward satisfaction of
the Statement.

During the term of a Statement, LFS will hold shares in escrow to secure payment
of the higher sales charge applicable to Class A shares actually purchased.
Dividends and capital gains will be paid on all escrowed shares and these shares
will be released when the amount indicated has been purchased. A Statement does
not obligate the investor to buy or a fund to sell the amount of the Statement.

If a shareholder exceeds the amount of the Statement and reaches an amount which
would qualify for a further quantity discount, a retroactive price adjustment
will be made at the time of expiration of the Statement. The resulting
difference in offering price will purchase additional shares for the
shareholder's account at the applicable offering price. As a part of this
adjustment, the FSF shall return to LFD the excess commission previously paid
during the thirteen-month period.

If the amount of the Statement is not purchased, the shareholder shall remit to
LFD an amount equal to the difference between the sales charge paid and the
sales charge that should have been paid. If the shareholder fails within twenty
days after a written request to pay such difference in sales charge, LFS will
redeem that number of escrowed Class A shares to equal such difference. The
additional amount of FSF discount from the applicable offering price shall be
remitted to the shareholder's FSF of record.

Additional information about and the terms of Statements of Intent are available
from your FSF, or from LFS at 1-800-345-6611.

REINSTATEMENT PRIVILEGE. An investor who has redeemed Class A, B, or C shares
may, upon request, reinstate within one year a portion or all of the proceeds of
such sale in shares of the same Class of any fund at the NAV next determined
after LFS receives a written reinstatement request and payment. Any EWC paid at
the time of the redemption will be credited to the shareholder upon
reinstatement. The period between the redemption and the reinstatement will not
be counted in aging the reinstated shares for purposes of calculating any EWC
or conversion date. Investors who desire to exercise this privilege should
contact their FSF or LFS. Shareholders may exercise this Privilege an unlimited
number of times. Exercise of this privilege does not alter the Federal income
tax treatment of any capital gains realized on the prior sale of fund shares,
but to the extent any such shares were sold at a loss, some or all of the loss
may be disallowed for tax purposes. Consult your tax advisor.

PRIVILEGES OF COLONIAL EMPLOYEES OR FINANCIAL SERVICE FIRMS. Class A shares of
certain funds may be sold at NAV to the following individuals whether currently
employed or retired: Trustees of funds advised or administered by the Advisor;
directors, officers and employees of the Advisor, LFD and other companies
affiliated with the Advisor; registered representatives and employees of FSFs
(including their affiliates) that are parties to dealer agreements or other
sales arrangements with LFD; and such persons' families and their beneficial
accounts.



                                      B-14
<PAGE>   53


SPONSORED ARRANGEMENTS. Class A shares of certain funds may be purchased at a
reduced or no sales charge pursuant to sponsored arrangements, which include
programs under which an organization makes recommendations to, or permits group
solicitation of, its employees, members or participants in connection with the
purchase of shares of the fund on an individual basis. The amount of the sales
charge reduction will reflect the anticipated reduction in sales expense
associated with sponsored arrangements. The reduction in sales expense, and
therefore the reduction in sales charge, will vary depending on factors such as
the size and stability of the organization's group, the term of the
organization's existence and certain characteristics of the members of its
group. The funds reserve the right to revise the terms of or to suspend or
discontinue sales pursuant to sponsored plans at any time.

Class A shares of certain funds may also be purchased at reduced or no sales
charge by clients of dealers, brokers or registered investment advisors that
have entered into agreements with LFD pursuant to which the funds are included
as investment options in programs involving fee-based compensation arrangements,
and by participants in certain retirement plans.

WAIVER OF EARLY WITHDRAWAL CHARGES (EWCs) (Classes A, B and C) EWCs may be
waived on redemptions in the following situations with the proper documentation:


1.       Death. EWCs may be waived on redemptions within one year following the
         death of (i) the sole shareholder on an individual account, (ii) a
         joint tenant where the surviving joint tenant is the deceased's spouse,
         or (iii) the beneficiary of a Uniform Gifts to Minors Act ("UGMA"),
         Uniform Transfers to Minors Act ("UTMA") or other custodial account.
         If, upon the occurrence of one of the foregoing, the account is
         transferred to an account registered in the name of the deceased's
         estate, the EWCs will be waived on any redemption from the estate
         account occurring within one year after the death. If the Class B
         shares are not redeemed within one year of the death, they will remain
         subject to the applicable EWC, when redeemed from the transferee's
         account. If the account is transferred to a new registration and then a
         redemption is requested, the applicable EWC will be charged.

2.       Disability. EWCs may be waived on redemptions occurring within one year
         after the sole shareholder on an individual account or a joint tenant
         on a spousal joint tenant account becomes disabled (as defined in
         Section 72(m)(7) of the Internal Revenue Code). To be eligible for such
         waiver, (i) the disability must arise AFTER the purchase of shares AND
         (ii) the disabled shareholder must have been under age 65 at the time
         of the initial determination of disability. If the account is
         transferred to a new registration and then a redemption is requested,
         the applicable EWC will be charged.

3.       Death of a trustee. EWCs may be waived on redemptions occurring upon
         dissolution of a revocable living or grantor fund following the death
         of the sole trustee where (i) the grantor of the fund is the sole
         trustee and the sole life beneficiary, (ii) death occurs following the
         purchase AND (iii) the fund document provides for dissolution of the
         fund upon the trustee's death. If the account is transferred to a new
         registration (including that of a successor trustee), the applicable
         EWC will be charged upon any subsequent redemption.

4.       Returns of excess contributions. EWCs may be waived on redemptions
         required to return excess contributions made to retirement plans or
         individual retirement accounts, so long as the FSF agrees to return the
         applicable portion of any commission paid by Colonial.

5.       Qualified Retirement Plans. EWCs may be waived on redemptions required
         to make distributions from qualified retirement plans following normal
         retirement (as stated in the Plan document).

The EWC also may be waived where the FSF agrees to return all or an agreed upon
portion of the commission earned on the sale of the shares being redeemed.

<PAGE>   54
                       MISCELLANEOUS INVESTMENT PRACTICES

SHORT-TERM TRADING

      In seeking the Fund's investment objective, the Advisor will buy or sell
portfolio securities whenever it deems appropriate. The Advisor's decision will
not generally be influenced by how long the Fund may have owned the security.
From time to time the Fund will buy securities intending to seek short-term
trading profits. A change in the securities held by the Fund is known as
"portfolio turnover" and generally involves some expense to the Fund. These
expenses may include brokerage commissions or dealer mark-ups and other
transaction costs on both the sale of securities and the reinvestment of the
proceeds in other securities. If sales of portfolio securities cause the Fund
to realize net short-term capital gains, such gains will be taxable as ordinary
income. As a result of the Fund's investment policies, under certain market
conditions the Fund's portfolio turnover rate may be higher than that of other
mutual Funds. The Fund's portfolio turnover rate for a fiscal year is the
ratio of the lesser of purchases or sales of portfolio securities to the monthly
average of the value of portfolio securities, excluding securities whose
maturities at acquisition were one year or less. The Fund's portfolio turnover
rate is not a limiting factor when the Advisor considers a change in the Fund's
portfolio. The rate of portfolio turnover for the fund is expected to be
approximately 50%.


LOWER RATED BONDS


      Lower rated bonds are those rated lower than Baa by Moody's Investor
Service, Inc., ("Moody's"), BBB by Standard & Poor's Rating division of The
McGraw-Hill Companies, Inc. ("Standard & Poor's"), or comparable unrated debt
securities. Relative to debt securities of higher quality,


 1.  an economic downturn or increased interest rates may have a more
     significant effect on the yield, price and potential for default for lower
     rated bonds;

 2.  the secondary market for lower rated bonds may at times become less liquid
     or respond to adverse publicity or investor perceptions, increasing the
     difficulty in valuing or disposing of the bonds;

 3.  the Advisor's credit analysis of lower rated bonds may have a greater
     impact on the Fund's achievement of its investment objective and


 4.  lower rated bonds may be less sensitive to interest rate changes, but are
     more sensitive to adverse economic developments.


     In addition, certain lower rated bonds do not pay interest in cash on a
current basis. However, the Fund will accrue and distribute this interest on a
current basis, and may have to sell securities to generate cash for
distributions.

SMALL COMPANIES

     Smaller, less well-established companies may offer greater opportunities
for capital appreciation than larger, better established companies, but may also
involve certain special risks related to limited product lines, markets, or
financial resources and dependence on a small management group. Their securities
may trade less frequently, in smaller volumes, and fluctuate more sharply in
value than securities of larger companies.


FOREIGN SECURITIES


      The Fund may invest in securities traded in markets outside the United
States. Foreign investments can be affected favorably or unfavorably by changes
in currency rates and in exchange control regulations. There may be less
publicly available information about a foreign company than about a U.S.
company, and foreign companies may not be subject to accounting, auditing and
financial reporting standards comparable to those applicable to U.S. companies.
Securities of some foreign companies are less liquid or more volatile than
securities of U.S. companies, and foreign brokerage


                                      B-16

<PAGE>   55

commissions and custodian fees may be higher than in the United States.
Investments in foreign securities can involve other risks different from those
affecting U.S. investments, including local political or economic developments,
expropriation or nationalization of assets and imposition of withholding taxes
on dividend or interest payments. Foreign securities, like other assets of the
Fund, will be held by the Fund's custodian or by a subcustodian or depository.
See also "Foreign Currency Transactions" below.



     The Fund may invest in certain passive foreign investment companies
(PFICs) which may be subject to U.S. federal income tax on a portion of any
"excess distribution" or gain (PFIC tax) related to the investment. The PFIC tax
is the highest ordinary income rate, and it could be increased by an interest
charge on the deemed tax deferral.


     The Fund may elect to include in its income its pro rata share of the
ordinary earnings and net capital gain of PFICs. This election requires certain
annual information from the PFICs which in many cases may be difficult to
obtain. An alternative election would permit the Fund to recognize as income
any appreciation (but not depreciation) on its holdings of PFICs as of the end
of its fiscal year. See "Taxation" below.

STRIPPED SECURITIES (STRIPS)

     The Fund may invest in stripped securities (e.g. zero coupon securities)
which are securities issued at a significant discount from face value and pay
interest only at maturity rather than at intervals during the life of the
security and in certificates representing undivided interests in the interest or
principal of mortgage-backed securities (interest only/principal only), which
tend to be more volatile than other types of securities. The Fund will accrue
and distribute income from stripped securities and certificates on a current
basis and may have to sell securities to generate cash for distributions.

STEP COUPON BONDS (STEPS)

     The Fund may invest in debt securities which do not pay interest for a
stated period of time and then pay interest at a series of different rates for a
series of periods. In addition to the risks associated with the credit rating of
the issuers, these securities are subject to the volatility risk of stripped
securities for the period when no interest is paid.

PAY-IN-KIND (PIK) SECURITIES

     The Fund may invest in securities which pay interest either in cash or
additional securities at the issuer's option. These securities are generally
high yield securities and in addition to the other risks associated with
investing in high yield securities are subject to the risks that the interest
payments which consist of additional securities are also subject to the risks of
high yield securities.

MONEY MARKET INSTRUMENTS


     GOVERNMENT OBLIGATIONS are issued by the U.S. or foreign governments, their
subdivisions, agencies and instrumentalities. Supranational obligations are
issued by supranational entities and are generally designed to promote economic
improvements. CERTIFICATES OF DEPOSITS are issued against deposits in a
commercial bank with a defined return and maturity. BANKER'S ACCEPTANCES are
used to finance the import, export or storage of goods and are "accepted" when
guaranteed at maturity by a bank. COMMERCIAL PAPER is promissory notes issued by
businesses to finance short-term needs (including those with floating or
variable interest rates, or including a frequent interval put feature).
SHORT-TERM CORPORATE OBLIGATIONS are bonds and notes (with one year or less to
maturity at the time of purchase) issued by businesses to finance long-term
needs. PARTICIPATION INTERESTS include the underlying securities and any related
guaranty, letter of credit, or collateralization arrangement which the Fund
would be allowed to invest in directly.

SECURITIES LOANS

     The Fund may make secured loans of its portfolio securities. The risks in
lending portfolio securities, as with other extensions of credit, consist of
possible delay in recovery of the securities or possible loss of rights in the
collateral should the borrower fail financially. As a matter of policy,
securities loans are made to banks and broker-dealers pursuant to agreements
requiring that loans be continuously secured by collateral in cash or short-term
debt obligations at least equal at all times to the value of the securities on
loan. The borrower pays to the Fund an amount equal to any dividends or
interest received on securities lent. The Fund retains all or a portion of the
interest received on investment of the cash collateral or receives a fee from
the borrower. Although voting rights, or rights to consent, with respect to the
loaned securities pass to the borrower, the Fund retains the right to call the
loans at any time on reasonable notice, and it will do so in order that the
securities may be voted by the Fund if the holders of such securities are asked
to vote upon or consent to matters materially affecting the investment. The
Fund may also call such loans in order to sell the securities involved.

FORWARD COMMITMENTS ("WHEN-ISSUED" AND "DELAYED DELIVERY" SECURITIES)


     The Fund may enter into contracts to purchase securities for a fixed price
at a future date beyond customary settlement time ("forward commitments" and
"when issued securities") if the Fund holds until the settlement date, in a
segregated account, cash or liquid securities in an amount sufficient to meet
the purchase price, or if the Fund enters into offsetting contracts for the
forward sale of other securities it owns. Forward commitments may be considered
securities in themselves, and involve a risk of loss if the value of the
security to be purchased declines prior to the settlement date. Where such
purchases are made through dealers, the Fund relies on the dealer to consummate
the sale. The dealer's failure to do so may result in the loss to the Fund of
an advantageous yield or price. Although the Fund will generally enter into
forward commitments with the intention of acquiring securities for its portfolio
or for delivery pursuant to options contracts it has entered into, the Fund may
dispose of a commitment prior to settlement if the Advisor deems it appropriate
to do so. The Fund may realize short-term profits or losses upon the sale of
forward commitments.


MORTGAGE DOLLAR ROLLS

     In a mortgage dollar roll, the Fund sells a mortgage-backed security and
simultaneously enters into a commitment to purchase a similar security at a
later date. The Fund either will be paid a fee by the counterparty upon
entering into the transaction or will be entitled to purchase the similar
security at a discount. As with any forward commitment, mortgage dollar rolls
involve the risk that the counterparty will fail to deliver the new security on
the settlement date, which may deprive the Fund of obtaining a beneficial
investment. In addition, the security to be delivered in the future may turn out
to be inferior to the security sold upon entering into the transaction. Also,
the transaction costs may exceed the return earned by the Fund from the
transaction.

REPURCHASE AGREEMENTS

     The Fund may enter into repurchase agreements. A repurchase agreement is a
contract under which the Fund acquires a security for a relatively short period
(usually not more than one week) subject to the obligation of the seller to
repurchase and the Fund to resell such security at a fixed time and price
(representing the Fund's cost plus interest). It is the Fund's present
intention to enter into repurchase agreements only with commercial banks and
registered broker-dealers and only with respect to obligations of the U.S.
government or its agencies or instrumentalities. Repurchase agreements may also
be viewed as loans made by the Fund which are collateralized by the securities
subject to repurchase. The Advisor will monitor such transactions to determine
that the value of the underlying securities is at least equal at all times to
the total amount of the repurchase obligation, including the interest factor. If
the seller defaults, the Fund could realize a loss on the sale of the
underlying security to the extent that the proceeds of sale including accrued
interest are less than the resale price provided in the agreement including
interest. In addition, if the seller should be involved in bankruptcy or
insolvency proceedings, the Fund may incur delay and costs in selling the
underlying security or may suffer a loss of


                                      B-18

<PAGE>   57
principal and interest if the Fund is treated as an unsecured creditor and
required to return the underlying collateral to the seller's estate.

REVERSE REPURCHASE AGREEMENTS


     In a reverse repurchase agreement, the Fund sells a security and agrees to
repurchase the same security at a mutually agreed upon date and price. A reverse
repurchase agreement may also be viewed as the borrowing of money by the Fund
and, therefore, as a form of leverage. The Fund will invest the proceeds of
borrowings under reverse repurchase agreements. In addition, the Fund will
enter into a reverse repurchase agreement only when the interest income expected
to be earned from the investment of the proceeds is greater than the interest
expense of the transaction. The Fund may not enter into reverse repurchase
agreements exceeding in the aggregate one-third of the market value of its total
assets, less liabilities other than the obligations created by reverse
repurchase agreements. The Fund will establish and maintain with its custodian
a separate account with a segregated portfolio of securities in an amount at
least equal to its purchase obligations under its reverse repurchase agreements.


OPTIONS ON SECURITIES

        WRITING COVERED OPTIONS. The Fund may write covered call options and
covered put options on securities held in its portfolio when, in the opinion of
the Advisor, such transactions are consistent with the Fund's investment
objective and policies. Call options written by the Fund give the purchaser the
right to buy the underlying securities from the Fund at a stated exercise
price; put options give the purchaser the right to sell the underlying
securities to the Fund at a stated price. The Fund may write only covered
options, which 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
comparable securities satisfying the cover requirements of securities
exchanges). In the case of put options, the Fund will hold cash liquid assets
equal to the price to be paid if the option is exercised. In addition, the Fund
will be considered to have covered a put or call option if and to the extent
that it holds an option that offsets some or all of the risk of the option it
has written. The Fund may write combinations of covered puts and calls on the
same underlying security.

       The Fund will receive a premium from writing a put or call option, which
increases the Fund's return on the underlying security if the option expires
unexercised or is closed out at a profit. The amount of the premium reflects,
among other things, the relationship between the exercise price and the current
market value of the underlying security, the volatility of the underlying
security, the amount of time remaining until expiration, current interest rates,
and the effect of supply and demand in the options market and in the market for
the underlying security. By writing a call option, the Fund limits its
opportunity to profit from any increase in the market value of the underlying
security above the exercise price of the option but continues to bear the risk
of a decline in the value of the underlying security. By writing a put option,
the Fund assumes the risk that it may be required to purchase the underlying
security for an exercise price higher than its then-current market value,
resulting in a potential capital loss unless the security subsequently
appreciates in value.

       The Fund may terminate an option that it has written prior to its
expiration by entering into a closing purchase transaction in which it purchases
an offsetting option. The Fund realizes a profit or loss from a closing
transaction if the cost of the transaction (option premium plus transaction
costs) is less or more than the premium received from writing the option.
Because increases in the market price of a call option generally reflect
increases in the market price of the security underlying the option, any loss
resulting from a closing purchase transaction may be offset in whole or in part
by unrealized appreciation of the underlying security.


                                      B-19

<PAGE>   58
       If the Fund writes a call option but does not own the underlying
security, and when it writes a put option, the Fund may be required to deposit
cash or securities with its broker as "margin" or collateral for its obligation
to buy or sell the underlying security. As the value of the underlying security
varies, the Fund may have to deposit additional margin with the broker. Margin
requirements are complex and are fixed by individual brokers, subject to minimum
requirements currently imposed by the Federal Reserve Board and by stock
exchanges and other self-regulatory organizations.

PURCHASING PUT OPTIONS

       The Fund may purchase put options to protect its portfolio holdings in
an underlying security against a decline in market value. Such hedge protection
is provided during the life of the put option since the Fund, as holder of the
put option, is able to sell the underlying security at the put exercise price
regardless of any decline in the underlying security's market price. For a put
option to be profitable, the market price of the underlying security must
decline sufficiently below the exercise price to cover the premium and
transaction costs. By using put options in this manner, the Fund will reduce
any profit it might otherwise have realized from appreciation of the underlying
security by the premium paid for the put option and by transaction costs.

PURCHASING CALL OPTIONS

       The Fund may purchase call options to hedge against an increase in the
price of securities that the Fund wants ultimately to buy. Such hedge
protection is provided during the life of the call option since the Fund, as
holder of the call option, is able to buy the underlying security at the
exercise price regardless of any increase in the underlying security's market
price. In order for a call option to be profitable, the market price of the
underlying security must rise sufficiently above the exercise price to cover the
premium and transaction costs. These costs will reduce any profit the Fund
might have realized had it bought the underlying security at the time it
purchased the call option.

OVER-THE-COUNTER (OTC) OPTIONS


       The Staff of the Division of Investment Management of the Securities and
Exchange Commission, (the "SEC") has taken the position that OTC options
purchased by the Fund and assets held to cover OTC options written by the Fund
are illiquid securities. Although the Staff has indicated that it is continuing
to evaluate this issue, pending further developments, the Fund intends to enter
into OTC options transactions only with primary dealers in U.S. Government
Securities and, in the case of OTC options written by the Fund, only pursuant
to agreements that will assure that the Fund will at all times have the right
to repurchase the option written by it from the dealer at a specified formula
price. The Fund will treat the amount by which such formula price exceeds the
amount, if any, by which the option may be "in-the-money" as an illiquid
investment.


RISK FACTORS IN OPTIONS TRANSACTIONS

       The successful use of the Fund's options strategies depends on the
ability of the Advisor to forecast interest rate and market movements correctly.

       When it purchases an option, the Fund runs the risk that it will lose
its entire investment in the option in a relatively short period of time, unless
the Fund exercises the option or enters into a closing sale transaction with
respect to the option during the life of the option. If the price of the
underlying security does not rise (in the case of a call) or fall (in the case
of a put) to an extent sufficient to cover the option premium and transaction
costs, the Fund will lose part or all of its investment in the option. This
contrasts with an investment by the Fund in the underlying securities, since
the Fund may continue to hold its investment in those securities
notwithstanding the lack of a change in price of those securities.


                                      B-20

<PAGE>   59
       The effective use of options also depends on the Fund's ability to
terminate option positions at times when the Advisor deems it desirable to do
so. Although the Fund will take an option position only if the Advisor believes
there is a liquid secondary market for the option, there is no assurance that
the Fund will be able to effect closing transactions at any particular time or
at an acceptable price.

       If a secondary trading market in options were to become unavailable, the
Fund could no longer engage in closing transactions. Lack of investor interest
might adversely affect the liquidity of the market for particular options or
series of options. A marketplace may discontinue trading of a particular option
or options generally. In addition, a market could become temporarily unavailable
if unusual events -- such as volume in excess of trading or clearing capability
- -- were to interrupt normal market operations.

        A marketplace may at times find it necessary to impose restrictions on
particular types of options transactions, which may limit the Fund's ability to
realize its profits or limit its losses.

       Disruptions in the markets for the securities underlying options
purchased or sold by the Fund could result in losses on the options. If trading
is interrupted in an underlying security, the trading of options on that
security is normally halted as well. As a result, the Fund as purchaser or
writer of an option will be unable to close out its positions until options
trading resumes, and it may be faced with losses if trading in the security
reopens at a substantially different price. In addition, the Options Clearing
Corporation (OCC) or other options markets may impose exercise restrictions. If
a prohibition on exercise is imposed at the time when trading in the option has
also been halted, the Fund as purchaser or writer of an option will be locked
into its position until one of the two restrictions has been lifted. If a
prohibition on exercise remains in effect until an option owned by the Fund has
expired, the Fund could lose the entire value of its option.

       Special risks are presented by internationally-traded options. Because of
time differences between the United States and various foreign countries, and
because different holidays are observed in different countries, foreign options
markets may be open for trading during hours or on days when U.S. markets are
closed. As a result, option premiums may not reflect the current prices of the
underlying interest in the United States.

FUTURES CONTRACTS AND RELATED OPTIONS


       Upon entering into futures contracts, in compliance with the SEC
requirements, cash or liquid securities, equal in value to the amount of the
Fund's obligation under the contract (less any applicable margin deposits and
any assets that constitute "cover" for such obligation), will be segregated with
the Fund's custodian.


       A futures contract sale creates an obligation by the seller to deliver
the type of instrument called for in the contract in a specified delivery month
for a stated price. A futures contract purchase creates an obligation by the
purchaser to take delivery of the type of instrument called for in the contract
in a specified delivery month at a stated price. The specific instruments
delivered or taken at settlement date are not determined until on or near that
date. The determination is made in accordance with the rules of the exchanges on
which the futures contract was made. Futures contracts are traded in the United
States only on commodity exchange or boards of trade -- known as "contract
markets" -- approved for such trading by the Commodity Futures Trading
Commission (CFTC), and must be executed through a futures commission merchant or
brokerage firm which is a member of the relevant contract market.

       Although futures contracts by their terms call for actual delivery or
acceptance of commodities or securities, the contracts usually are closed out
before the settlement date without the making or taking of delivery. Closing out
a futures contract sale is effected by purchasing a futures contract for the
same aggregate amount of the specific type of financial instrument or commodity
with the same delivery date. If the price of the initial sale of the futures
contract exceeds the price of the offsetting purchase, the seller is paid the
difference and realizes a gain. Conversely, if the price of the offsetting
purchase exceeds the price of the initial sale, the seller realizes a loss.
Similarly, the closing out of a futures


                                      B-21

<PAGE>   60
contract purchase is effected by the purchaser's entering into a futures
contract sale. If the offsetting sale price exceeds the purchase price, the
purchaser realizes a gain, and if the purchase price exceeds the offsetting sale
price, the purchaser realizes a loss.

       Unlike when the Fund purchases or sells a security, no price is paid or
received by the Fund upon the purchase or sale of a futures contract, although
the Fund is required to deposit with its custodian in a segregated account in
the name of the futures broker an amount of cash and/or U.S. government
securities. This amount is known as "initial margin." The nature of initial
margin in futures transactions is different from that of margin in security
transactions in that futures contract margin does not involve the borrowing of
Funds by the Fund to finance the transactions. Rather, initial margin is in
the nature of a performance bond or good faith deposit on the contract that is
returned to the Fund upon termination of the futures contract, assuming all
contractual obligations have been satisfied. Futures contracts also involve
brokerage costs.

       Subsequent payments, called "variation margin," to and from the broker
(or the custodian) are made on a daily basis as the price of the underlying
security or commodity fluctuates, making the long and short positions in the
futures contract more or less valuable, a process known as "marking to market."

       The Fund may elect to close some or all of its futures positions at any
time prior to their expiration. The purpose of making such a move would be to
reduce or eliminate the hedge position then currently held by the Fund. The
Fund may close its positions by taking opposite positions which will operate to
terminate the Fund's position in the futures contracts. Final determinations of
variation margin are then made, additional cash is required to be paid by or
released to the Fund, and the Fund realizes a loss or a gain. Such closing
transactions involve additional commission costs.

OPTIONS ON FUTURES CONTRACTS

            The Fund will enter into written options on futures contracts only
when, in compliance with the SEC's requirements, cash or liquid securities equal
in value to the commodity value (less any applicable margin deposits) have been
deposited in a segregated account of the Fund's custodian. The Fund may
purchase and write call and put options on futures contracts it may buy or sell
and enter into closing transactions with respect to such options to terminate
existing positions. The Fund may use such options on futures contracts in lieu
of writing options directly on the underlying securities or purchasing and
selling the underlying futures contracts. Such options generally operate in the
same manner as options purchased or written directly on the underlying
investments.

            As with options on securities, the holder or writer of an option may
terminate his position by selling or purchasing an offsetting option. There is
no guarantee that such closing transactions can be effected.

            The Fund will be required to deposit initial margin and maintenance
margin with respect to put and call options on futures contracts written by it
pursuant to brokers' requirements similar to those described above.

RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS

            Successful use of futures contracts by the Fund is subject to the
Advisor's ability to predict correctly movements in the direction of interest
rates and other factors affecting securities markets.

            Compared to the purchase or sale of futures contracts, the purchase
of call or put options on futures contracts 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 purchase
of a call or put option on a futures contract would result in a loss to the
Fund when the purchase or sale of a futures contract would not, such as when
there is no movement in the prices of the hedged investments. The writing of an
option on a futures contract involves risks similar to those risks relating to
the sale of futures contracts.


                                      B-22

<PAGE>   61
            There is no assurance that higher than anticipated trading activity
or other unforeseen events might not, at times, render certain market clearing
facilities inadequate, and thereby result in the institution, by exchanges, of
special procedures which may interfere with the timely execution of customer
orders.

            To reduce or eliminate a hedge position held by the Fund, the Fund
may seek to close out a position. The ability to establish and close out
positions will be subject to the development and maintenance of a liquid
secondary market. It is not certain that this market will develop or continue to
exist for a particular futures contract. Reasons for the absence of a liquid
secondary market on an exchange include the following: (i) there may be
insufficient trading interest in certain contracts or options; (ii) restrictions
may be imposed by an exchange on opening transactions or closing transactions or
both; (iii) trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of contracts or options, or underlying
securities; (iv) unusual or unforeseen circumstances may interrupt normal
operations on an exchange; (v) the facilities of an exchange or a clearing
corporation may not at all times be adequate to handle current trading volume;
or (vi) one or more exchanges could, for economic or other reasons, decide or be
compelled at some future date to discontinue the trading of contracts or options
(or a particular class or series of contracts or options), in which event the
secondary market on that exchange (or in the class or series of contracts or
options) would cease to exist, although outstanding contracts or options on the
exchange that had been issued by a clearing corporation as a result of trades on
that exchange would continue to be exercisable in accordance with their terms.

INDEX FUTURES CONTRACTS

            An index futures contract is a contract to buy or sell units of an
index at a specified future date at a price agreed upon when the contract is
made. Entering into a contract to buy units of an index is commonly referred to
as buying or purchasing a contract or holding a long position in the index.
Entering into a contract to sell units of an index is commonly referred to as
selling a contract or holding a short position. A unit is the current value of
the index. The Fund may enter into stock index futures contracts, debt index
futures contracts, or other index futures contracts appropriate to its
objective(s). The Fund may also purchase and sell options on index futures
contracts.

            There are several risks in connection with the use by the Fund of
index futures as a hedging device. One risk arises because of the imperfect
correlation between movements in the prices of the index futures and movements
in the prices of securities which are the subject of the hedge. The Advisor will
attempt to reduce this risk by selling, to the extent possible, futures on
indices the movements of which will, in its judgment, have a significant
correlation with movements in the prices of the Fund's portfolio securities
sought to be hedged.


     Successful use of index futures by the Fund for hedging purposes is also
subject to the Advisor's ability to predict correctly movements in the direction
of the market. It is possible that, where the Fund has sold futures to hedge
its portfolio against a decline in the market, the index on which the futures
are written may advance and the value of securities held in the Fund's
portfolio may decline. If this occurs, the Fund would lose money on the futures
and also experience a decline in the value in its portfolio securities. It is
also possible that, if the Fund has hedged against the possibility of a decline
in the market adversely affecting securities held in its portfolio and
securities prices increase instead, the Fund will lose part or all of the
benefit of the increased values of those securities that it has hedged because
it will have offsetting losses in its futures positions. In addition, in such
situations, if the Fund has insufficient cash, it may have to sell securities
to meet daily variation margin requirements.



                                      B-23

<PAGE>   62
      In addition to the possibility that there may be an imperfect correlation,
or no correlation at all, between movements in the index futures and the
securities of the portfolio being hedged, the prices of index futures may not
correlate perfectly with movements in the underlying index due to certain market
distortions. First, all participants in the futures markets are subject to
margin deposit and maintenance requirements. Rather than meeting additional
margin deposit requirements, investors may close futures contracts through
offsetting transactions which would distort the normal relationship between the
index and futures markets. Second, margin requirements in the futures market are
less onerous than margin requirements in the securities market, and as a result
the futures market may attract more speculators than the securities market.
Increased participation by speculators in the futures market may also cause
temporary price distortions. Due to the possibility of price distortions in the
futures market and also because of the imperfect correlation between movements
in the index and movements in the prices of index futures, even a correct
forecast of general market trends by the Advisor may still not result in a
successful hedging transaction.

OPTIONS ON INDEX FUTURES

      Options on index futures are similar to options on securities except that
options on index futures give the purchaser the right, in return for the premium
paid, to assume a position in an index futures contract (a long position if the
option is a call and a short position if the option is a put), 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 which represents the amount by which the
market price of the index 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 index future. If an option is exercised on 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 the closing
level of the index on which the future is based on the expiration date.
Purchasers of options who fail to exercise their options prior to the exercise
date suffer a loss of the premium paid.

OPTIONS ON INDICES

      As an alternative to purchasing call and put options on index futures, the
Fund may purchase call and put options on the underlying indices themselves.
Such options could be used in a manner identical to the use of options on index
futures.

FOREIGN CURRENCY TRANSACTIONS

      The Fund may engage in currency exchange transactions to protect against
uncertainty in the level of future currency exchange rates.


      The Fund may engage in both "transaction hedging" and "position hedging."
When it engages in transaction hedging, the Fund enters into foreign currency
transactions with respect to specific receivables or payables of the Fund
generally arising in connection with the purchase or sale of its portfolio
securities. The Fund will engage in transaction hedging when it desires to
"lock in" the U.S. dollar price of a security it has agreed to purchase or sell,
or the U.S. dollar equivalent of a dividend or interest payment in a foreign
currency. By transaction hedging the Fund attempts to protect itself against a
possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the applicable foreign currency during the period between the
date on which the security is purchased or sold, or on which the dividend or
interest payment is declared, and the date on which such payments are made or
received.


      The Fund may purchase or sell a foreign currency on a spot (or cash)
basis at the prevailing spot rate in connection with the settlement of
transactions in portfolio securities denominated in that foreign currency. The
Fund


                                      B-24

<PAGE>   63
may also enter into contracts to purchase or sell foreign currencies at a future
date ("forward contracts") and purchase and sell foreign currency futures
contracts.

      For transaction hedging purposes the Fund may also purchase
exchange-listed and over-the-counter call and put options on foreign currency
futures contracts and on foreign currencies. Over-the-counter options are
considered to be illiquid by the SEC staff. A put option on a futures contract
gives the Fund the right to assume a short position in the futures contract
until expiration of the option. A put option on currency gives the Fund the
right to sell a currency at an exercise price until the expiration of the
option. A call option on a futures contract gives the Fund the right to assume
a long position in the futures contract until the expiration of the option. A
call option on currency gives the Fund the right to purchase a currency at the
exercise price until the expiration of the option.

      When it engages in position hedging, the Fund enters into foreign
currency exchange transactions to protect against a decline in the values of the
foreign currencies in which its portfolio securities are denominated (or an
increase in the value of currency for securities which the Fund expects to
purchase, when the Fund holds cash or short-term investments). In connection
with position hedging, the Fund may purchase put or call options on foreign
currency and foreign currency futures contracts and buy or sell forward
contracts and foreign currency futures contracts. The Fund may also purchase or
sell foreign currency on a spot basis.

      The precise matching of the amounts of foreign currency exchange
transactions and the value of the portfolio securities involved will not
generally be possible since the future value of such securities in foreign
currencies will change as a consequence of market movements in the value of
those securities between the dates the currency exchange transactions are
entered into and the dates they mature.

      It is impossible to forecast with precision the market value of portfolio
securities at the expiration or maturity of a forward or futures contract.
Accordingly, it may be necessary for the Fund to purchase additional foreign
currency on the spot market (and bear the expense of such purchase) if the
market value of the security or securities being hedged is less than the amount
of foreign currency the Fund is obligated to deliver and if a decision is made
to sell the security or securities and make delivery of the foreign currency.
Conversely, it may be necessary to sell on the spot market some of the foreign
currency received upon the sale of the portfolio security or securities if the
market value of such security or securities exceeds the amount of foreign
currency the Fund is obligated to deliver.

      Transaction and position hedging do not eliminate fluctuations in the
underlying prices of the securities which the Fund owns or intends to purchase
or sell. They simply establish a rate of exchange which one can achieve at some
future point in time. Additionally, although these techniques tend to minimize
the risk of loss due to a decline in the value of the hedged currency, they tend
to limit any potential gain which might result from the increase in value of
such currency.

CURRENCY FORWARD AND FUTURES CONTRACTS

      Upon entering into such contracts, in compliance with the SEC's
requirements, cash or liquid securities, equal in value to the amount of the
Fund's obligation under the contract (less any applicable margin deposits and
any assets that constitute "cover" for such obligation), will be segregated with
the Fund's custodian.

      A forward currency contract involves an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract as agreed by the parties, at a price set at the time of
the contract. In the case of a cancelable contract, the holder has the
unilateral right to cancel the contract at maturity by paying a specified fee.
The contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. A
contract generally has no deposit requirement, and no commissions are charged at
any stage for trades. A currency futures contract is a standardized contract for
the future


                                      B-25

<PAGE>   64
delivery of a specified amount of a foreign currency at a future date at a price
set at the time of the contract. Currency futures contracts traded in the United
States are designed and traded on exchanges regulated by the CFTC, such as the
New York Mercantile Exchange.

      Forward currency contracts differ from currency futures contracts in
certain respects. For example, the maturity date of a forward contract may be
any fixed number of days from the date of the contract agreed upon by the
parties, rather than a predetermined date in a given month. Forward contracts
may be in any amounts agreed upon by the parties rather than predetermined
amounts. Also, forward contracts are traded directly between currency traders so
that no intermediary is required. A forward contract generally requires no
margin or other deposit. At the maturity of a forward or futures contract, the
Fund may either accept or make delivery of the currency specified in the
contract, or at or prior to maturity enter into a closing transaction involving
the purchase or sale of an offsetting contract. Closing transactions with
respect to forward contracts are usually effected with the currency trader who
is a party to the original forward contract. Closing transactions with respect
to futures contracts are effected on a commodities exchange; a clearing
corporation associated with the exchange assumes responsibility for closing out
such contracts.

      Positions in currency futures contracts may be closed out only on an
exchange or board of trade which provides a secondary market in such contracts.
Although the Fund intends to purchase or sell currency futures contracts only
on exchanges or boards of trade where there appears to be an active secondary
market, there is no assurance that a secondary market on an exchange or board of
trade will exist for any particular contract or at any particular time. In such
event, it may not be possible to close a futures position and, in the event of
adverse price movements, the Fund would continue to be required to make daily
cash payments of variation margin.

CURRENCY OPTIONS

      In general, options on currencies operate similarly to options on
securities and are subject to many similar risks. Currency options are traded
primarily in the over-the-counter market, although options on currencies have
recently been listed on several exchanges. Options are traded not only on the
currencies of individual nations, but also on the European Currency Unit
("ECU"). The ECU is composed of amounts of a number of currencies, and is the
official medium of exchange of the European Economic Community's European
Monetary System.

      The Fund will only purchase or write currency options when the Advisor
believes that a liquid secondary market exists for such options. There can be no
assurance that a liquid secondary market will exist for a particular option at
any specified time. Currency options are affected by all of those factors which
influence exchange rates and investments generally. To the extent that these
options are traded over the counter, they are considered to be illiquid by the
SEC staff.

      The value of any currency, including the U.S. dollars, may be affected by
complex political and economic factors applicable to the issuing country. In
addition, the exchange rates of currencies (and therefore the values of currency
options) may be significantly affected, fixed, or supported directly or
indirectly by government actions. Government intervention may increase risks
involved in purchasing or selling currency options, since exchange rates may not
be free to fluctuate in respect to other market forces.

      The value of a currency option reflects the value of an exchange rate,
which in turn reflects relative values of two currencies, the U.S. dollar and
the foreign currency in question. Because currency transactions occurring in the
interbank market involve substantially larger amounts than those that may be
involved in the exercise of currency options, investors may be disadvantaged by
having to deal in an odd lot market for the underlying currencies in connection
with options at prices that are less favorable than for round lots. Foreign
governmental restrictions or taxes could result in adverse changes in the cost
of acquiring or disposing of currencies.


                                      B-26

<PAGE>   65
      There is no systematic reporting of last sale information for currencies
and there is no regulatory requirement that quotations available through dealers
or other market sources be firm or revised on a timely basis. Available
quotation information is generally representative of very large round-lot
transactions in the interbank market and thus may not reflect exchange rates for
smaller odd-lot transactions (less than $1 million) where rates may be less
favorable. The interbank market in currencies is a global, around-the-clock
market. To the extent that options markets are closed while the markets for the
underlying currencies remain open, significant price and rate movements may take
place in the underlying markets that cannot be reflected in the options markets.

SETTLEMENT PROCEDURES

      Settlement procedures relating to the Fund's investments in foreign
securities and to the Fund's foreign currency exchange transactions may be more
complex than settlements with respect to investments in debt or equity
securities of U.S. issuers, and may involve certain risks not present in the
Fund's domestic investments, including foreign currency risks and local custom
and usage. Foreign currency transactions may also involve the risk that an
entity involved in the settlement may not meet its obligations.

FOREIGN CURRENCY CONVERSION


      Although foreign exchange dealers do not charge a fee for currency
conversion, they do realize a profit based on the difference (spread) between
prices at which they are buying and selling various currencies. Thus, a dealer
may offer to sell a foreign currency to the Fund at one rate, while offering a
lesser rate of exchange should the Fund desire to resell that currency to the
dealer. Foreign currency transactions may also involve the risk that an entity
involved in the settlement may not meet its obligation.


INVERSE FLOATERS

      Inverse floaters are derivative securities whose interest rates vary
inversely to changes in short-term interest rates and whose values fluctuate
inversely to changes in long-term interest rates. The value of certain inverse
floaters will fluctuate substantially more in response to a given change in
long-term rates than would a traditional debt security. These securities have
investment characteristics similar to leverage, in that interest rate changes
have a magnified effect on the value of inverse floaters.

RULE 144A SECURITIES

      The Fund may purchase securities that have been privately placed but that
are eligible for purchase and sale under Rule 144A under the Securities Act of
1933 (the "1933 Act"). That Rule permits certain qualified institutional buyers,
such as the Fund, to trade in privately placed securities that have not been
registered for sale under the 1933 Act. The Advisor, under the supervision of
the Board of Trustees, will consider whether securities purchased under Rule
144A are illiquid and thus subject to the Fund's investment restriction on
illiquid securities. A determination of whether a Rule 144A security is liquid
or not is a question of fact. In making this determination, the Advisor will
consider the trading markets for the specific security, taking into account the
unregistered nature of a Rule 144A security. In addition, the Advisor could
consider the (1) frequency of trades and quotes, (2) number of dealers and
potential purchasers, (3) dealer undertakings to make a market, and (4) nature
of the security and of marketplace trades (e.g., the time needed to dispose of
the security, the method of soliciting offers, and the mechanics of transfer).

                                   TAX MATTERS

FEDERAL INCOME TAX MATTERS

   Federal Taxation of the Fund

The ability of the Fund to qualify for taxation as a regulated investment
company under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code") requires, among other things, that the Fund distribute to its
shareholders with respect to each year at least 90% of the sum of (1) its net
tax-exempt interest income and (2) its taxable net investment income (including,
generally, taxable interest, dividends and certain other income, less certain
expenses, and the excess, if any, of net short-term capital gain over net
long-term capital loss) (the "Distribution Requirement").

In addition to satisfying the Distribution Requirement for each taxable year, a
regulated investment company must derive at least 90% of its gross income from
dividends, interest, certain payments with respect to securities loans, gains
from the sale or other disposition of stock or securities or foreign currencies
(to the extent such currency gains are directly related to the regulated
investment company's principal business of investing in stock or securities, or
options and futures with respect to stock or securities) and other income
(including but not limited to gains from options, futures or forward contracts)
derived with respect to its business of investing in such stock, securities or
currencies (the "Income Requirement").

Further, the Fund must satisfy an asset diversification test in order to
qualify as a regulated investment company. Under this test, at the close of each
quarter of the Fund's taxable year, at least 50% of the value of the Fund's
assets must consist of cash and cash items (including receivables), U.S.
Government securities, securities of other regulated investment companies, and
securities of other issuers (as to which the Fund has not invested more than 5%
of the value of the Fund's total assets in securities of such issuer and as to
which the Fund does not hold more than 10% of the outstanding voting securities
of such issuer), and no more than 25% of the value of its total assets may be
invested in the securities of any one issuer (other than U.S. Government
securities and securities of other regulated investment companies), or in two or
more issuers which the Fund controls and which are engaged in the same or
similar trades or businesses or related trades or businesses.

A 4% non-deductible excise tax is imposed on a regulated investment company that
fails to distribute in each calendar year an amount at least equal to the sum of
98% of ordinary taxable income for the calendar year and 98% of capital gain net
income for the one-year period ended on October 31 of such calendar year (or, at
the election of a regulated investment company having a taxable year ending
November 30 or December 31, for its taxable year), plus 100% of any
undistributed income from the preceding year. For the foregoing purposes, a
regulated investment company is treated as having distributed any amount on
which it is subject to income tax for any taxable year ending in such calendar
year.

The Fund generally intends to make sufficient distributions or deemed
distributions of its ordinary taxable income and capital gain net income prior
to the end of each calendar year to avoid liability for the excise tax. However,
investors should note that the Fund may in certain circumstances be required to
liquidate portfolio investments to make sufficient distributions to avoid excise
tax liability. In addition, the Fund may elect to pay the excise tax liability
if it determines that the costs of making an excise tax distribution are greater
than the excise tax liability that would be due upon the failure to make such
excise tax distribution.



                                      B-28

<PAGE>   67

If the Fund does not qualify for taxation as a regulated investment company for
any taxable year, the Fund's income will be taxed subject to corporate income
taxes imposed at the Fund level, and all distributions from earnings and
profits, including distributions of net exempt-interest income and net capital
gain (i.e., the excess, if any, of net long-term capital gain over net
short-term capital loss), will be taxable to shareholders as ordinary income. In
addition, in order to requalify for taxation as a regulated investment company,
the Fund may be required to recognize unrealized gains, pay substantial taxes
and interest, and make certain distributions.


Federal Taxation of Shareholders


Shareholders will be subject to federal income taxes on distributions, whether
received in cash or additional shares. Distributions of net income and
short-term capital gains, if any, will be taxable to shareholders as ordinary
income. Distributions designated by the Fund as deriving from net gains on
securities held for more than one year will be taxable to shareholders as
long-term capital gain (generally taxed at a rate of 20% to noncorporate
shareholders), without regard to how long a shareholder has held shares in the
Fund.


Dividends and distributions on the Fund's shares are generally subject to
federal income tax as described herein to the extent they do not exceed the
Fund's realized income and gains, even though such dividends and distributions
may economically represent a return of a particular shareholder's investment.
Such distributions are likely to occur in respect of shares purchased at a time
when the Fund's net asset value reflects gains that are either unrealized, or
realized but not distributed. Such realized gains may be required to be
distributed even when the Fund's net asset value also reflects unrealized
losses.


SALES OR REDEMPTIONS OF SHARES. From time to time the Fund may make a tender or
repurchase offer for its shares. It is expected that the terms of any such offer
will require a tendering shareholder to tender all shares, held or considered
under Code rules to be held by such shareholder. Shareholders who tender all
shares held, or considered held, by them will be treated as having sold such
shares and generally will realize a capital gain or loss. If, however, a
shareholder tenders fewer than all of its shares, such shareholder may be
treated as having received a taxable dividend upon the tender of its shares. In
such a case, there is a remote risk that non-tendering shareholders will be
treated as having received taxable distributions from the Fund.


BACKUP WITHHOLDING. The Fund generally is required to withhold and remit to the
U.S. Treasury 31% of the taxable dividends and other distributions paid to
non-corporate shareholders who fail to furnish the Fund with a


                                      B-29

<PAGE>   68
correct taxpayer identification number, who have under reported dividends or
interest income, or who fail to certify to the Fund that they are not subject
to such withholding. An individual's taxpayer identification number is his or
her social security number.

FOREIGN INVESTORS. Non-resident alien individuals, foreign corporations and
certain other foreign entities generally will be subject to a U.S. withholding
tax at a rate of 30% on the Fund's distributions from its ordinary income and
the excess of its net short-term capital gain over its net long-term capital
loss, unless the tax is reduced or eliminated by an applicable tax treaty.
Distributions from the excess of the Fund's net capital gain received by such
shareholders and any gain from the sale or other disposition of shares of the
Fund generally will not be subject to U.S. Federal income taxation, provided
that non-resident alien status has been certified by the shareholder. Different
U.S. tax consequences may result if the shareholder is engaged in a trade or
business in the United States, is present in the United States for a sufficient
period of time during a taxable year to be treated as a U.S. resident, or fails
to provide any required certifications regarding status as a non-resident alien
investor. Foreign shareholders should consult their tax advisors regarding the
U.S. and foreign tax consequences of an investment in the Fund.

The Internal Revenue Service recently revised its regulations affecting the
application to foreign investors of the back-up withholding and withholding tax
rules described above. The new regulations will generally be effective for
payments made after December 31, 2000. In some circumstances, the new rules will
increase the certification and filing requirements imposed on foreign investors
in order to qualify for exemption from the 31% back-up withholding tax and for
reduced withholding tax rates under income tax treaties. Foreign investors in
the Fund should consult their tax advisors with respect to the potential
application of these new regulations.

The foregoing is a general, abbreviated summary of the provisions of the Code
and regulations thereunder presently in effect as they directly govern the
taxation of the Fund and shareholders. These provisions are subject to change
by legislative or administrative action, and any such change may be retroactive
with respect to Fund transactions.


                              SHAREHOLDER LIABILITY

      Under Massachusetts law, shareholders could, under certain circumstances,
be held personally liable for the obligations of the Fund. However, the
Declaration disclaims shareholder liability for acts or obligations of the Fund
and requires that a notice of such disclaimer be given in each agreement,
obligation or instrument entered into or executed by the Fund or the Trustees.
The Declaration provides for indemnification out of Fund property for all loss
and expense of any shareholder held personally liable for the obligations of the
Fund. Thus, the risk of a


                                      B-30

<PAGE>   69
shareholder's incurring financial loss on account of shareholder liability is
limited to circumstances (which are considered remote) in which the Fund would
be unable to meet its obligations and the disclaimer was inoperative.



                                    CUSTODIAN

      The Chase Manhattan Bank, located at 270 Park Avenue, New York, New York
10017-2070, is the Fund's custodian. The custodian is responsible for
safeguarding the Fund's cash and securities, receiving and delivering
securities and collecting the Fund's interest and dividends.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the financial position of the Colonial Investment Grade
Bond Fund, at January 13, 2000 in conformity with generally accepted accounting
principles.

Item 29.  Indemnification.

          The Agreement and Declaration of Trust, as amended, filed as Exhibit
          (a)(1) and (a)(2) to this Registration Statement provides for
          indemnification to each of the Registrant's Trustees and officers
          against all liabilities and expenses incurred in acting


                                       C-2
<PAGE>   74


               as Trustee or officer, except in the case of wilful misfeasance,
               bad faith, gross negligence or reckless disregard of the duties
               involved in the conduct of such Trustees and officers.

               Insofar as indemnification for liability arising under the
               Securities Act of 1933 may be permitted to trustees, officers
               and controlling persons of the Registrant pursuant to the
               foregoing provisions, or otherwise, the Registrant has been
               advised that in the opinion of the Securities and Exchange
               Commission such indemnification is against public policy as
               expressed in the Act and is, therefore, unenforceable. In the
               event that a claim for indemnification against such liabilities
               (other than the payment by the Registrant of expenses incurred
               or paid by a trustee, officer or controlling person of the
               Registrant in the successful defense of any action, suit or
               proceeding) is asserted by such trustee, officer or controlling
               person in connection with the securities being registered, the
               Registrant will, unless in the opinion of its counsel the matter
               has been settled by controlling precedent, submit to a court of
               appropriate jurisdiction the question whether such
               indemnification by it is against public policy as expressed in
               the Act and will be governed by the final adjudication of such
               issue.


               The Registrant, its advisor, Colonial Management Associates, Inc.
               and their respective trustees, directors and officers are insured
               by a directors and officers/errors and omissions liability
               policy.

                                   ARTICLE II

                                     PURPOSE

         The purpose of the Trust is to provide investors a managed investment
primarily in securities, commodities and debt instruments and other securities
and rights of a financial character.

                                   ARTICLE III

                                     SHARES

Division of Beneficial Interest

         Section 1. The Trustees may, without Shareholder approval, authorize
one or more classes of Shares (which classes may be divided into two or more
series), Shares of each such class or series having such preferences, voting
powers, terms of redemption, if any, and special or relative rights or
privileges (including conversion rights, if any) as the Trustees may determine
and as shall be set forth in the By-Laws. The number of Shares of each class or
series authorized shall be unlimited, except as the By-Laws may otherwise
provide, and the Shares so authorized may be represented in part by fractional
shares. The Trustees may from time to time divide or combine the Shares of any
class or series into a greater or lesser number without thereby changing the
proportionate beneficial interest in the class or series.

Ownership of Shares

         Section 2. The ownership of Shares shall be recorded on the books of
the Trust or its transfer or similar agent. No certificates certifying the
ownership of Shares shall be issued except as the Trustees may otherwise
determine from time to time. The Trustees may make such rules as they consider
appropriate for the issuance of Share certificates, the transfer of Shares and
similar matters. The record books of the Trust as kept by the Trust or any
transfer or similar agent of the Trust, as the case may be, shall be conclusive
as to who are the Shareholders of each class or series and as to the number of
Shares of each class or series held from time to time by each Shareholder.

Investments in the Trust

         Section 3. The Trustees shall accept investments in the Trust from such
persons and on such terms and, subject to any requirements of law, for such
consideration, which may consist of cash or tangible or intangible property or a
combination thereof, as they or the ByLaws from time to time authorize.

<PAGE>   5
No Preemptive Rights

         Section 4. Shareholders shall have no preemptive or other right to
receive, purchase or subscribe for any additional Shares or other securities
issued by the Trust.

Status of Shares and Limitation of Personal Liability

         Section 5. Shares shall be deemed to be personal property giving only
the rights provided in this Declaration of Trust or the By-Laws. Every
Shareholder by virtue of having become a Shareholder shall be held to have
expressly assented and agreed to the terms of this Declaration of Trust and the
By-Laws and to have become a party hereto and thereto. The death of a
Shareholder during the continuance of the Trust shall not operate to terminate
the same nor entitle the representative of any deceased Shareholder to an
accounting or to take any action in court or elsewhere against the Trust or the
Trustees, but only to the rights of said decedent under this Trust. Ownership of
Shares shall not entitle the Shareholder to any title in or to the whole or any
part of the Trust property or right to call for a partition or division of the
same or for an accounting, nor shall the ownership of Shares constitute the
Shareholders partners. Neither the Trust nor the Trustees, nor any officer,
employee or agent of the Trust, shall have any power to bind personally any
Shareholder, nor except as specifically provided herein to call upon any
Shareholder for the payment of any sum of money or assessment whatsoever other
than such as the Shareholder may at any time personally agree to pay.

                                   ARTICLE IV

                                  THE TRUSTEES

Number of Trustees and Term of Office

         Section 1. Subject to the voting powers of one or more classes or
series of Shares as set forth in the By-Laws, the number of Trustees shall be
such number as shall be fixed from time to time by a written instrument signed
by a majority of the Trustees, provided, however, that the number of Trustees
shall in no event be less than three (3). No reduction in the number of Trustees
shall have the effect of removing any Trustee from office prior to the
expiration of his or her term unless the Trustee is specifically removed
pursuant to Section 2 of this Article at the time of the decrease. The Board of
Trustees shall be divided into three classes. The number of Trustees in each
class shall be determined by resolution of the Board of Trustees. The initial
Trustees, each of whom shall serve until the first meeting of Shareholders at
which Trustees are elected and until his or her successor is elected and
qualified, or until he or she sooner dies, resigns or is removed, shall be John
V. Carberry and such other persons as the Trustee or Trustees then in office
shall, prior to any sale of Shares pursuant to a public offering, appoint. The
term of office of all of the initial Trustees shall expire on the date of the
first annual meeting of Shareholders or special meeting in lieu thereof, which
annual or special meeting shall be called to be held not more than fifteen


                                       -5-
<PAGE>   6
months after Shares are first sold pursuant to a public offering. The term of
office of the first class shall expire on the date of the second annual meeting
of Shareholders or any special meeting in lieu thereof. The term of office of
the second class shall expire on the date of the third annual meeting of
Shareholders or any special meeting in lieu thereof. The term of office of the
third class shall expire on the date of the fourth annual meeting of
Shareholders or any special meeting in lieu thereof. Upon expiration of the term
of office of each class as set forth above, the number of Trustees in such
class, as determined by the Board of Trustees, shall be elected for a term
expiring on the date of the third annual meeting of Shareholders or any special
meeting in lieu thereof following such expiration to succeed the Trustees whose
terms of office expire. The Trustees shall be elected at an annual meeting of
the Shareholders or a special meeting in lieu thereof, except as provided in
Section 2 of this Article.

Vacancies; Removal

         Section 2. Subject to the voting powers of one or more classes or
series of Shares as set forth in the By-Laws, any vacancies occurring in the
Board of Trustees may be filled by the Trustees if, immediately after filling
any such vacancy, at least two-thirds of the Trustees then holding office shall
have been elected to such office by the Shareholders. In the event that at any
time less than a majority of the Trustees then holding office were elected to
such office by the Shareholders, the Trustees shall call a meeting of
Shareholders for the purpose of electing Trustees. At any meeting called for
such purpose and subject to the voting powers of one or more classes or series
of Shares as set forth in the By-Laws, a Trustee may be removed, with or without
cause, by vote of seventy-five percent (75%) of the outstanding Shares of the
classes or series entitled to vote for the election of such Trustee. By vote of
seventy-five percent (75%) of the Trustees then in office, the Trustees may
remove a Trustee with or without cause.

Effect of Death, Resignation, etc. of a Trustee

         Section 3. The death, declination, resignation, retirement, removal, or
incapacity of the Trustees, or any one of them, shall not operate to annul the
Trust or to revoke any existing agency created pursuant to the terms of this
Declaration of Trust.

Powers

         Section 4. Subject to the provisions of this Declaration of Trust, the
business of the Trust shall be managed by the Trustees, and they shall have all
powers necessary or convenient to carry out that responsibility. Without
limiting the foregoing, the Trustees may adopt ByLaws not inconsistent with this
Declaration of Trust providing for the conduct of the business of the Trust and
may amend and repeal them to the extent that such By-Laws do not reserve that
right to the Shareholders of one or more classes or series. Subject to the
voting power of one or more classes or series of shares as set forth in the
By-Laws, the Trustees may fill vacancies in or add to their number, including
vacancies resulting from increases in their


                                       -6-

number, and may elect and remove such officers and appoint and terminate such
agents as they consider appropriate; they may appoint from their own number, and
terminate, any one or more committees consisting of two or more Trustees,
including an executive committee which may, when the Trustees are not in
session, exercise some or all of the power and authority of the Trustees as the
Trustees may determine; they may appoint an advisory board, the members of which
shall not be Trustees and need not be Shareholders, they may employ one or more
custodians of the assets of the Trust and may authorize such custodians to
employ subcustodians and to deposit all or any part of such assets in a system
or systems for the central handling of securities, retain a transfer agent or a
Shareholder services agent, or both, provide for the distribution of Shares by
the Trust, through one or more principal underwriters or otherwise, set record
dates for the determination of Shareholders with respect to various matters, and
in general delegate such authority as they consider desirable to any officer of
the Trust, to any committee of the Trustees and to any agent or employee of the
Trust or to any such custodian or underwriter.

         Without limiting the foregoing, the Trustees shall have power and

         otherwise;

                  (f) To the extent necessary or appropriate to give effect to
         the preferences, special or relative rights and privileges of any
         classes or series of Shares, to allocate assets, liabilities, income
         and expenses of the Trust to a particular class or classes or series of
         Shares or to apportion the same among two or more classes or series;

                  (g) To consent to or participate in any plan for the
         reorganization, consolidation or merger of any corporation or issuer,

         held in the Trust; to consent to any contract, lease, mortgage,

         committee, depositary, voting trustee or otherwise, and in that
         connection to deposit any security with, or transfer any security to,
         any such committee, depositary or trustee, and to delegate to them such
         power and authority with relation to any security (whether or not so
         deposited or transferred) as the Trustees shall deem proper, and to

         proper;

                  (i) To compromise, arbitrate or otherwise adjust claims in

         distributions and principal on its portfolio investments, and insurance
         policies insuring the Shareholders, Trustees, officers, employees,
         agents, investment advisors or managers, principal underwriters or
         independent contractors of the Trust individually against all claims
         and liabilities of every nature arising by reason of holding, being or
         having held any such office or position, or by reason of any action
         alleged to have been taken or omitted by any such person as
         Shareholder, Trustee, officer, employee, agent, investment adviser or
         manager, principal underwriter or independent contractor, including any

         such person against such liability; and

                  (n) To pay pensions for faithful service, as deemed
         appropriate by the Trustees, and to adopt, establish and carry out

                                       -8-
<PAGE>   9
         and provisions, including the purchasing of life insurance and annuity
         contracts as a means of providing such retirement and other benefits,
         for any or all of the Trustees, officers, employees and agents of the
         Trust.

                  (o) To purchase or otherwise acquire Shares.

         The Trustees shall not in any way be bound or limited by any present or
future law or custom in regard to investments by Trustees. Except as otherwise
provided herein or from time to time in the By-Laws, any action to be taken by
the Trustees may be taken by a majority of the Trustees present at a meeting of
the Trustees (a quorum being present), within or without Massachusetts. Except
as otherwise provided herein or from time to time in the ByLaws, any action to
be taken by the Trustees may be taken at a meeting held by means of a conference
telephone or other communications equipment by means of which all persons
participating in the meeting can hear each other at the same time and
participation by such means shall constitute a presence in person at a meeting,
or by written consents of a majority of the Trustees then in office (or such
greater number as may be required by this Declaration of Trust or otherwise).

Payment of Expense by Trust

         Section 5. The Trustees are authorized to pay, or to cause to be paid
out of the principal or income of the Trust, or partly out of principal and
partly out of income, as they deem fair, all expenses, fees, charges, taxes and
liabilities incurred or arising in connection with the Trust, or in connection
with the management thereof, including, but not limited to, the Trustees'
compensation and such expenses and charges for the services of the Trust's
officers, employees, investment adviser, or manager, principal underwriter,
auditor, counsel, custodian, transfer agent, Shareholder servicing agent, and
such other agents or independent contractors and such other expenses and charges
as the Trustees may deem necessary or proper to incur.

Ownership of Assets of the Trust

         Section 6. Title to all of the assets of the Trust shall at all times
be considered as vested in the Trustees.

Advisory, Management and Distribution

         Section 7. Subject to a favorable Majority Shareholder Vote, the
Trustees may, at any time and from time to time, contract for exclusive or
nonexclusive advisory and/or management services with any corporation, trust,
association or other organization (the "Adviser"), every such contract to comply
with such requirements and restrictions as may be set forth in the By-Laws; and
any such contract may contain such other terms interpretive of or in addition to
said requirements and restrictions as the Trustees may determine, including,
without limitation, authority to determine from time to time what investments
shall be


                                       -9-
<PAGE>   10
purchased, held, sold or exchanged and what portion, if any, of the assets of
the Trust shall be held uninvested and to make changes in the Trust's
investments. The Trustees may also, at any time and from time to time, contract
with the Adviser or any other corporation, trust, association or other
organization, appointing it exclusive or nonexclusive distributor or principal
underwriter for the Shares, every such contract to comply with such requirements
and restrictions as may be set forth in the By-Laws; and any such contract may
contain such other terms interpretive of or in addition to said requirements and
restrictions as the Trustees may determine.

         The fact that:

                           (i) any of the Shareholders, Trustees or officers of
                  the Trust is a shareholder, director, officer, partner,
                  trustee, employee, manager, adviser, principal underwriter or
                  distributor or agent of or for any corporation, trust,
                  association or other organization, or of or for any parent or
                  affiliate of any organization, with which an advisory or
                  management contract, or principal underwriter's or
                  distributor's contract, or transfer, Shareholder services or
                  other agency contract may have been or may hereafter be made
                  or that any such organization, or any parent or affiliate
                  thereof, is a Shareholder or has an interest in the Trust, or
                  that

                           (ii) any corporation, trust, association or other
                  organization with which an advisory or management contract or
                  principal underwriter's or distributor's contract or transfer,
                  Shareholder services or other agency contract may have been or
                  may hereafter be made also has an advisory or management
                  contract, or principal underwriter's or distributor's contract
                  or transfer, Shareholder services or other agency contract
                  with one or more other corporations, trusts, associations or
                  other organizations, or has other business or interests

shall not affect the validity of any such contract or disqualify any
Shareholder, Trustee or officer of the Trust from voting upon or executing the
same or create any liability or accountability to the Trust or its Shareholders.

                                    ARTICLE V

                    SHAREHOLDERS' VOTING POWERS AND MEETINGS

Voting Powers

         Section 1. Subject to the voting powers of one or more classes or
series of Shares as set forth in the By-Laws, the Shareholders shall have power
to vote only (i) for the election or removal of Trustees as provided in Article
IV, Section 1 or Section 2, (ii) with respect to


                                      -10-
<PAGE>   11
any Adviser as provided in Article IV, Section 7, (iii) with respect to any
termination of this Trust to the extent and as provided in Article IX, Section
4,(iv) with respect to any amendment of this Declaration of Trust to the extent
and as provided in Article IX, Section 7, (v) to the same extent as the
stockholders of a Massachusetts business corporation as to whether or not a
court action, proceeding or claim should or should not be brought or maintained
derivatively or as a class action on behalf of the Trust or the Shareholders,
and (vi) with respect to such additional matters relating to the Trust as may be
required by law, this Declaration of Trust, the By-Laws or any registration of
the Trust with the Securities and Exchange Commission (or any successor agency)
or any state, or as the Trustees may consider necessary or desirable. Each whole
Share shall be entitled to one vote as to any matter on which it is entitled to
vote and each fractional Share shall be entitled to a proportionate fractional
vote, except as otherwise provided in the By-Laws. Notwithstanding any other
provision of this Declaration of Trust, on any matter submitted to a vote of
Shareholders, all Shares of the Trust then entitled to vote shall, except as
otherwise provided in the By-Laws or required by law, be voted in the aggregate
as a single class without regard to classes or series of Shares. There shall be
no cumulative voting in the election of Trustees. Shares may be voted in person
or by proxy. A proxy with respect to Shares held in the name of two or more
persons shall be valid if executed by any one of them unless at or prior to
exercise of the proxy the Trust receives a specific written notice to the
contrary from any one of them. A proxy purporting to be executed by or on behalf
of a Shareholder shall be deemed valid unless challenged at or prior to its
exercise and the burden of proving invalidity shall rest on the challenger.
Until Shares of a particular class or series are issued, the Trustees may
exercise all rights of Shareholders and may take any action required by law,
this Declaration of Trust or the By-Laws to be taken by Shareholders as to such
class or series.

Voting Power and Meetings

         Section 2. There shall be an annual meeting of the Shareholders on the
date fixed in the By-Laws at the office of the Trust in Boston, Massachusetts,
or at such other place as may be designated in the call thereof, which call
shall be made by the Trustees. In the event that such meeting is not held in any
year on the date fixed in the By-Laws, whether the omission be by oversight or
otherwise, a subsequent special meeting may be called by the Trustees and held
in lieu of the annual meeting with the same effect as though held on such date.
Special meetings of Shareholders of any or all classes or series may also be
called by the Trustees from time to time for the purpose of taking action upon
any matter requiring the vote or authority of the Shareholders of such class or
series as herein provided or upon any other matter deemed by the Trustees to be
necessary or desirable. Written notice of any meeting of Shareholders shall be
given or caused to be given by the Trustees by mailing such notice at least
seven days before such meeting, postage prepaid, stating the time, place and
purpose of the meeting, to each Shareholder entitled to vote at such meeting at
the Shareholder's address as it appears on the records of the Trust. If the
Trustees shall fail to call or give notice of any meeting of Shareholders for a
period of 30 days after written application by Shareholders holding at least 10%
of the Shares then outstanding of all classes and series entitled to vote at
such meeting


                                      -11-
<PAGE>   12
requesting a meeting to be called for a purpose requiring action by the
Shareholders as provided herein or in the By-Laws, then Shareholders holding at
least 10% of the Shares then outstanding of all classes and series entitled to
vote at such meeting may call and give notice of such meeting, and thereupon the
meeting shall be held in the manner provided for herein in case of call thereof
by the Trustees. Notice of a meeting need not be given to any Shareholder if a
written waiver of notice, executed by him or her before or after the meeting, is
filed with the records of the meeting, or to any Shareholder who attends the
meeting without protesting prior thereto or at its commencement the lack of
notice to him or her.

Quorum and Required Vote

         Section 3. Thirty percent (30%) of the Shares entitled to vote on a
particular matter shall be a quorum for the transaction of business at a
Shareholders' meeting, except that where the By-Laws require that holders of any
class or series shall vote as an individual class or series, then thirty percent
(30%) of the aggregate number of Shares of that class or series entitled to vote
shall be necessary to constitute a quorum for the transaction of business by
that class or series. Any lesser number, however, shall be sufficient for
adjournments. Any adjourned session or sessions may be held within a reasonable
time after the date set for the original meeting without the necessity of
further notice. Except when a different vote is required by any provision of
this Declaration of Trust or the By-Laws, a majority of the Shares voted shall
decide any questions and a plurality shall elect a Trustee, provided that where
the By-Laws require that the holders of any class or series shall vote as an
individual class or series a majority of the Shares of that class or series
voted on the matter (or a plurality with respect to the election of a Trustee)
shall decide that matter insofar as that class or series is concerned.

Conversion

         Section 4. Notwithstanding any other provision of this Declaration of
Trust, the conversion of the Trust from a "closed-end company" to an "open-end
company," as those terms are defined in Sections 5(a)(2) and 5(a)(1),
respectively, of the 1940 Act as in effect on August 1, 1999, together with any
necessary amendments to the Declaration of Trust to permit such a conversion,
shall require the affirmative vote or consent of the holders of at least 66 2/3%
of the Shares of each class entitled to vote. Such affirmative vote or consent
shall be in addition to the vote or consent of the holders of the Shares
otherwise required by law or by any agreement between the Trust and any national
securities exchange.

Action by Written Consent

         Section 5. Any action taken by Shareholders may be taken without a
meeting if a majority of Shareholders entitled to vote on the matter (or such
larger proportion thereof as shall be required by any express provision of this
Declaration of Trust or the By-Laws) consent to the action in writing and such
written consents are filed with the records of the meetings of


                                      -12-
<PAGE>   13
Shareholders. Such consent shall be treated for all purposes as a vote taken at
a meeting of Shareholders.

Additional Provisions

         Section 6. The By-Laws may include further provisions, not inconsistent
with this Declaration of Trust, regarding Shareholders' voting powers, the
conduct of meetings and related matters.

                                   ARTICLE VI

               DISTRIBUTIONS AND DETERMINATION OF NET ASSET VALUE

Distributions

         Section 1. The Trustees may, but need not, each year distribute to the
Shareholders of any or all classes or series such income and gains, accrued or
realized, as the Trustees may determine, after providing for actual and accrued
expenses and liabilities (including such reserves as the Trustees may establish)
determined in accordance with good accounting practices and subject to the
preferences, special or relative rights and privileges of the various classes or
series of Shares. The Trustees shall have full discretion to determine which
items shall be treated as income and which items as capital and their
determination shall be binding upon the Shareholders. Distributions of each
year's income, if any be made, may be made in one or more payments, which shall
be in Shares, in cash or otherwise and on a date or dates and as of a record
date or dates determined by the Trustees. At any time and from time to time in
their discretion, the Trustees may distribute to the Shareholders as of a record
date or dates determined by the Trustees, in Shares, in cash or otherwise, all
or part of any gains realized on the sale or disposition of property or
otherwise, or all or part of any other principal of the Trust. Each distribution
pursuant to this Section 1 to the Shareholders of a particular class or series
shall be made ratably according to the number of Shares of such class or series
held by the several Shareholders on the applicable record date thereof, provided
that no distribution need be made on Shares purchased pursuant to orders
received, or for which payment is made, after such time or times as the Trustees
may determine. Any such distribution paid in Shares will be paid at the net
asset value thereof as determined in accordance with Section 2 of this Article
VI, or at such other value as may be specified by the By-Laws or as the Trustees
may from time to time determine, subject to applicable laws and regulations then
in effect.

Determination of Net Asset Value

         Section 2. At such times as the Trust shall have outstanding only one
class or series of Shares, the term "net asset value" of the Shares shall mean:
(i) the value of all the assets of the Trust; (ii) less the total liabilities of
the Trust; (iii) divided by the number of Shares outstanding, in each case at
the time of each determination. Any fractions involved in the


                                      -13-
<PAGE>   14
computation of net asset value per share shall be adjusted to the nearer cent
unless the Trustees shall determine to adjust such fractions to a fraction of a
cent. At such times as the Trust shall have outstanding more than one class or
series of Shares, the term "net asset value" of the Shares shall have such
meaning, with respect to the Shares of any particular class or series of Shares,
as shall from time to time be specified in the By-Laws.

         The Trustees, or any officer or officers or agent of the Trust
designated for the purpose by the Trustees, shall determine the net asset value
of the Shares, and the Trustees shall fix the times as of which the net asset
value of the Shares shall be determined and shall fix the periods during which
any such net asset value shall be effective as to sales and other transactions
in the Shares, except as such times and periods for any such transaction may be
fixed by other provisions of this Declaration of Trust or by the By-Laws.

         In valuing the portfolio investments for determination of net asset
value per share, securities for which market quotations are readily available
shall be valued at prices which, in the opinion of the Trustees, or any officer
or officers or agent of the Trust designated for the purpose by the Trustees,
most nearly represent the market value of such securities, which may, but need
not, be the most recent bid price obtained from one or more of the market makers
for such securities; other securities and assets shall be valued at fair value
as determined by or pursuant to the direction of the Trustees. Notwithstanding
the foregoing, short-term debt obligations, commercial paper and repurchase
agreements may be, but need not be, valued on the basis of quoted yields for
securities of comparable maturity, quality and type, or on the basis of
amortized cost. In determination of net asset value, dividends receivable and
accounts receivable for investments sold and for Shares sold shall be stated at
the amounts to be received therefor; and income receivable accrued daily on
bonds and notes owned shall be stated at the amount to be received. Any other
assets shall be stated at fair value as determined by the Trustees or such
officer, officers or agent pursuant to the Trustees' authority, except that no
value shall be assigned to goodwill, furniture, lists, reports, statistics or
other noncurrent assets other than real estate. Liabilities for accounts payable
for investments purchased shall be stated at the amounts payable therefor. In
determining net asset value of the Trust, the person or persons making such
determination on behalf of the Trust may include in liabilities such reserves,
estimated accrued expenses and contingencies as such person or persons may in
its, his, her or their best judgment deem fair and reasonable under the
circumstances. Any income, dividends and gains distributions payable by the
Trust shall be deducted as of such time or times on the record date therefor as
the Trustees shall determine.

         The manner of determining the net assets of the Trust or of determining
the net asset value of the Shares may from time to time be altered as necessary
or desirable in the judgment of the Trustees to conform to any other method
prescribed or permitted by any applicable law or regulation.

         Determinations under this Section 2 made in good faith and in
accordance with the provisions of the 1940 Act shall be binding on all parties
concerned.

                                   ARTICLE VII

                           COMPENSATION AND LIMITATION
                            OF LIABILITY OF TRUSTEES

Compensation

         Section 1. The Trustees as such shall be entitled to reasonable
compensation from the Trust; they may fix the amount of their compensation.
Nothing herein shall in any way prevent the employment of any Trustee for
advisory, management, legal, accounting, investment banking or other services
and payment for the same by the Trust.

Limitation of Liability

         Section 2. The Trustees shall not be responsible or liable in any event
for any neglect or wrongdoing of any officer, agent, employee, adviser or
principal underwriter of the Trust, nor shall any Trustee be responsible for the
act or omission of any other Trustee, but nothing herein contained shall protect
any Trustee against any liability to which he or she would otherwise be subject
by reason of wilful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of his or her office.

         Every note, bond, contract, instrument, certificate, Share or
undertaking and every other act or thing whatsoever executed or done by or on
behalf of the Trust or the Trustees or any of them in connection with the Trust
shall be conclusively deemed to have been executed or done only in or with
respect to their or his or her capacity as Trustees or Trustee, and such
Trustees or Trustee shall not be personally liable thereon.

                                  ARTICLE VIII

                                 INDEMNIFICATION

Trustees, Officers etc.

         Section 1. The Trust shall indemnify each of its Trustees and officers
(including persons who serve at the Trust's request as directors, officers or
trustees of another organization in which the Trust has any interest as a
shareholder, creditor or otherwise) (hereinafter referred to as a "Covered
Person") against all liabilities and expenses, including but not limited to
amounts paid in satisfaction of judgments, in compromise or as fines and
penalties, and counsel fees reasonably incurred by any Covered Person in
connection with the defense or disposition of any action, suit or other
proceeding, whether civil or criminal, before any court or administrative or
legislative body, in which such Covered Person may be or may have been involved
as a party or otherwise or with which such person may be or may have been
threatened, while in office or thereafter, by reason of being or having been
such a


                                      -15-
<PAGE>   16
Covered Person, except with respect to any matter as to which such Covered
Person shall have been finally adjudicated in a decision on the merits in any
such action, suit or other proceeding not to have acted in good faith in the
reasonable belief that such Covered Person's action was in the best interests of
the Trust and except that no Covered Person shall be indemnified against any
liability to the Trust or its Shareholders to which such Covered Person would
otherwise be subject by reason of wilful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office. Expenses, including counsel fees so incurred by any
such Covered Person (but excluding amounts paid in satisfaction of judgments, in
compromise or as fines or penalties), may be paid from time to time by the Trust
in advance of the final disposition of any such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such Covered Person to repay
amounts so paid to the Trust if it is ultimately determined that indemnification
of such expenses is not authorized under this Article, provided, that (a) such
Covered Person shall provide security for his or her undertaking, (b) the Trust
shall be insured against losses arising by reason of such Covered Person's
failure to fulfil his or her undertaking, or (c) a majority of the Trustees who
are disinterested persons and who are not Interested Persons (provided that a
majority of such Trustees then in office act on the matter), or independent
legal counsel in a written opinion shall determine, based on a review of readily
available facts (but not a full trial-type inquiry), that there is reason to
believe such Covered Person ultimately will be entitled to indemnification.

Compromise Payment

         Section 2. As to any matter disposed of (whether by a compromise
payment, pursuant to a consent decree or otherwise) without an adjudication in a
decision on the merits by a court, or by any other body before which the
proceeding was brought, that such Covered Person either (a) did not act in good
faith in the reasonable belief that such Covered Person's action was in the best
interests of the Trust or (b) is liable to the Trust or its Shareholders by
reason of wilful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of such Covered Person's office,
indemnification shall be provided if (a) approved as in the best interest of the
Trust, after notice that it involves such indemnification, by at least a
majority of the Trustees who are disinterested persons and are not Interested
Persons (provided that a majority of such Trustees then in office act on the
matter), upon a determination, based upon a review of readily available facts
(but not a full trial-type inquiry) that such Covered Person acted in good faith
in the reasonable belief that such Covered Person's action was in the best
interests of the Trust and is not liable to the Trust or its Shareholders by
reason of wilful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of such Covered Person's office, or (b)
there has been obtained an opinion in writing of independent legal counsel,
based upon a review of readily available facts (but not a full trial-type
inquiry), to the effect that such Covered Person appears to have acted in good
faith in the reasonable belief that such Covered Person's action was in the best
interests of the Trust and that such indemnification would not protect such
Covered Person against any liability to the Trust to which such Covered Person
would


                                      -16-
<PAGE>   17
otherwise be subject by reason of wilful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his or
her office. Any approval pursuant to this Section shall not prevent the recovery
from any Covered Person of any amount paid to such Covered Person in accordance
with this Section as indemnification if such Covered Person is subsequently
adjudicated by a court of competent jurisdiction not to have acted in good faith
in the reasonable belief that such Covered Person's action was in the best
interests of the Trust or to have been liable to the Trust or its Shareholders
by reason of wilful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such Covered Person's office.

Indemnification Not Exclusive

         Section 3. The right of indemnification hereby provided shall not be
exclusive of or affect any other rights to which any such Covered Person may be
entitled. As used in this Article VIII, the term "Covered Person" shall include
such person's heirs, executors and administrators, and a "disinterested person"
is a person against whom none of the actions, suits or other proceedings in
question or another action, suit or other proceeding on the same or similar
grounds is then or has been pending. Nothing contained in this Article shall
affect any rights to indemnification to which personnel of the Trust, other than
Trustees and officers, and other persons may be entitled by contract or
otherwise under law, nor the power of the Trust to purchase and maintain
liability insurance on behalf of such person.

Shareholders

         Section 4. In case any Shareholder or former Shareholder shall be held
to be personally liable solely by reason of his or her being or having been a
Shareholder and not because of his or her acts or omissions or for some other
reason, the Shareholder or former Shareholder (or his or her heirs, executors,
administrators or other legal representatives or, in the case of a corporation
or other entity, its corporate or other general successor) shall be entitled to
be held harmless from and indemnified against all loss and expense arising from
such liability.

                                   ARTICLE IX

                                  MISCELLANEOUS

Trustees, Shareholders etc. Not Personally Liable; Notice

         Section 1. All persons extending credit to, contracting with or having
any claim against the Trust shall look only to the assets of the Trust for
payment under such credit, contract or claim; and neither the Shareholders nor
the Trustees, nor any of the Trust's officers, employees or agents, whether
past, present or future, shall be personally liable therefor. Nothing in this
Declaration of Trust shall protect any Trustee against any liability to


                                      -17-
<PAGE>   18
which such Trustee would otherwise be subject by reason of wilful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of the office of Trustee.

         Every note, bond, contract, instrument, certificate or undertaking made
or issued by the Trustees or by any officers or officer shall give notice that
this Declaration of Trust is on file with the Secretary of State of The
Commonwealth of Massachusetts and shall recite that the same was executed or
made by or on behalf of the Trust or by them as Trustees or Trustee or as
officers or officer and not individually and that the obligations of such
instrument are not binding upon any of them or the Shareholders individually but
are binding only upon the assets and property of the Trust, and may contain such
further recital as he or she or they may deem appropriate, but the omission
thereof shall not operate to bind any Trustee or officers or officer or
Shareholders or Shareholder individually.

Trustee's Good Faith Action, Expert Advice, No Bond or Surety

         Section 2. The exercise by the Trustees of their powers and discretions
hereunder shall be binding upon everyone interested. A Trustee shall be liable
for his or her own wilful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of the office of Trustee, and
for nothing else, and shall not be liable for errors of judgment or mistakes of
fact or law. The Trustees may take advice of counsel or other experts with
respect to the meaning and operation of this Declaration of Trust, and shall be
under no liability for any act or omission in accordance with such advice or for
failing to follow such advice. The Trustees shall not be required to give any
bond as such, nor any surety if a bond is required.

Liability of Third Persons Dealing with Trustees

         Section 3. No person dealing with the Trustees shall be bound to make
any inquiry concerning the validity of any transaction made or to be made by the
Trustees or to see to the application of any payments made or property
transferred to the Trust or upon its order.

Duration and Termination of Trust

         Section 4. Unless terminated as provided herein, the Trust shall
continue without limitation of time. Subject to the voting powers of one or more
classes or series of Shares as set forth in the By-Laws, the Trust may be
terminated at any time by vote of Shareholders holding at least 66 2/3% of the
Shares entitled to vote or by the Trustees by written notice to the
Shareholders.

         Upon termination of the Trust, after paying or otherwise providing for
all charges, taxes, expenses and liabilities, whether due or accrued or
anticipated as may be determined by the Trustees, the Trust shall in accordance
with such procedures as the Trustees consider


                                      -18-
<PAGE>   19
appropriate reduce the remaining assets to distributable form in cash or shares
or other securities, or any combination thereof, and distribute the proceeds to
the Shareholders, ratably according to the number of Shares held by the several
Shareholders on the date of termination, except to the extent otherwise required
or permitted by the preferences and special or relative rights and privileges of
any classes or series of Shares.

Filing of Copies, References, Headings

         Section 5. The original or a copy of this instrument and of each
amendment hereto shall be kept at the office of the Trust, where it may be
inspected by any Shareholder. A copy of this instrument and of each amendment
hereto shall be filed by the Trust with the Secretary of The Commonwealth of
Massachusetts and with the Clerk of the City of Boston, as well as any other
governmental office where such filing may from time to time be required. Anyone
dealing with the Trust may rely on a certificate by an officer of the Trust as
to whether or not any such amendments have been made and as to any matters in
connection with the Trust hereunder; and, with the same effect as if it were the
original, may rely on a copy certified by an officer of the Trust to be a copy
of this instrument or of any such amendments. In this instrument and in any such
amendment, references to this instrument, and all expressions like "herein",
"hereof" and "hereunder", shall be deemed to refer to this instrument as amended
or affected by any such amendments. Headings are placed herein for convenience
of reference only and shall not be taken as a part hereof or control or affect
the meaning, construction or effect of this instrument. This instrument may be
executed in any number of counterparts, each of which shall be deemed an
original.

Applicable Law

         Section 6. This Declaration of Trust is made in The Commonwealth of
Massachusetts, and it is created under and is to be governed by and construed
and administered according to the laws of said Commonwealth. The Trust shall be
of the type commonly called a Massachusetts business trust, and without limiting
the provisions hereof, the Trust may exercise all powers which are ordinarily
exercised by such a trust.

Amendments

         Section 7. (a) Except to the extent that the By-Laws or applicable law
may require a higher vote or the separate vote of one or more classes or series
of Shares, and except as provided in paragraph (b) of this Section 7, this
Declaration of Trust may be amended at any time by an instrument in writing
signed by a majority of the then Trustees (1) when authorized so to do by a vote
of Shareholders holding a majority of the Shares entitled to vote or (2) without
Shareholder approval as may be necessary or desirable in order to authorize one
or more classes or series of Shares as in Section 1 of Article III. Amendments
having the purpose of changing the name of the Trust or of supplying any
omission, curing any ambiguity or


                                      -19-
<PAGE>   20
curing, correcting or supplementing any defective or inconsistent provision
contained herein shall not require authorization by Shareholder vote.

          (b) Except to the extent that the By-Laws or applicable law may
require a higher vote or the separate vote of one or more classes or series of
Shares, no amendment may be made under this Section 7 which shall amend, alter,
change or repeal any of the provisions of Article IV, Section 1, Article V,
Section 4 or this paragraph (b) unless the amendment effecting such amendment,
alteration, change or repeal shall receive the affirmative vote or consent of at
least 66 2/3% of the Shares entitled to vote. Such affirmative vote or consent
shall be in addition to the vote or consent of the holders of Shares otherwise
required by law or by the terms of any agreement between the Trust and any
national securities exchange.

(Declaration of Trust) dated November 16, 1999 of the Colonial Investment Grade
Interval Trust (Trust), a copy of which is on file in the Office of the

                  business of the Trust under that name or any other name as
                  they may from time to time determine.

         The foregoing Amendment shall become effective as of December 15, 1999.

             Agreement and Declaration of Trust and Principal Office

1.1 Agreement and  Declaration  of Trust.  These By-Laws shall be subject to the
Agreement  and  Declaration  of  Trust,  as from  time to  time in  effect  (the
"Declaration  of  Trust"),  of Colonial  Investment  Grade  Bond Fund (the
"Trust"), a Massachusetts business trust established by the Declaration of Trust
of the Trust.

1.2 Principal  Office of the Trust.  The principal  office of the Trust shall be

1.3 Shareholder  Meetings.  The annual meeting of the  shareholders of the Trust
shall be held between  April 1 and May 31 in each year,  beginning in 2000, on a
date and at a time within that period set by the Trustees.  A special meeting of
the shareholders of the Trust may be called at any time by the Trustees,  by the
president or, if the Trustees and the  president  shall fail to call any meeting
of shareholders for a period of 30 days after written application of one or more
shareholders who hold at least 10% of all outstanding  shares of the Trust, then
such shareholders may call such meeting.  Each call of a meeting shall state the
place, date, hour and purposes of the meeting.

principal office of the Trust, or, to the extent permitted by the Declaration of
Trust,  at such other place within the United  States as shall be  designated by
the Trustees or the president of the Trust.

1.5  Notice of  Meetings.  A written  notice of each  meeting  of  shareholders,

given by the secretary or an assistant  secretary or by an officer designated by
the  Trustees.  No  notice of any  meeting  of  shareholders  need be given to a

the proceedings of the meeting before being voted. Unless otherwise specifically
limited by their terms,  such proxies shall entitle the holders  thereof to vote
at any  adjournment  of such  meeting  but  shall  not be valid  after the final
adjournment  of such  meeting.  The placing of a  shareholder=s  name on a proxy
pursuant to  telephonic  or  electronically  transmitted  instructions  obtained
pursuant to procedures reasonably designed to verify that such instructions have
been authorized by such shareholder shall constitute  execution of such proxy by
or on behalf of such shareholder.

                                    Trustees

the Trustees  regarding the  investments  and other  affairs of the Trust.  Each
member of the advisory  board shall hold office  until the first  meeting of the
Trustees  following the next meeting of the shareholders and until his successor
is elected and  qualified,  or until he sooner  dies,  resigns,  is removed,  or
becomes  disqualified,  or until the advisory  board is sooner  abolished by the
Trustees.

         In addition,  the Trustees may appoint a dividend committee of not less
than three persons, at least one of whom shall be a Trustee of the Trust.

1.10 Special Meetings.  Special meetings of the Trustees may be held at any time
and at any  place  designated  in the call of the  meeting,  when  called by the
president or the treasurer or by two or more Trustees, sufficient notice thereof
being given to each Trustee by the secretary or an assistant secretary or by the
officer or one of the Trustees calling the meeting.

1.11 Notice.  It shall be sufficient notice of a special meeting to a Trustee to
send notice by mail at least  forty-eight  hours or by telegram or telecopier at

stating  the  number  of  shares  owned by him or her,  in such form as shall be
prescribed from time to time by the Trustees.  Such certificate  shall be signed

transfer agent may either issue receipts  therefor or may keep accounts upon the
books of the Trust for the record  holders of such  shares,  who shall in either
case be deemed,  for all purposes  hereunder,  to be the holders of certificates
for such shares as if they had accepted such  certificates  and shall be held to
have expressly assented and agreed to the terms hereof.

1.21 Loss of Certificates. In the case of the alleged loss or destruction or the
mutilation  of a share  certificate,  a duplicate  certificate  may be issued in

discontinue  the issuance of share  certificates  and may, be written  notice to
each shareholder,  require the surrender of share  certificates to the Trust for
cancellation.  Such surrender and cancellation shall not affect the ownership of
shares in the Trust.

<PAGE>   6


         The Trustees may fix in advance a time, which shall not be more than 90
days before the date of any meeting of  shareholders or the date for the payment
of any  dividend or making of any other  distribution  to  shareholders,  as the
record date for determining the  shareholders  having the right to notice and to
vote at such  meeting and any  adjournment  thereof or the right to receive such
dividend or distribution,  and in such case only  shareholders of record on such
record date shall have such right, notwithstanding any transfer of shares on the
books of the Trust after the record date; or without fixing such record date the
Trustees may for any of such  purposes  close the transfer  books for all or any
part of such period.

                                    Section 9

         The seal of the Trust shall,  subject to  alteration  by the  Trustees,
consist of a flat-faced circular die with the word "Massachusetts" together with
the name of the Trust and the year of its organization, cut or engraved thereon;
but, unless otherwise required by the Trustees,  the seal shall not be necessary
to be placed on, and its absence shall not impair the validity of, any document,
instrument or other paper executed and delivered by or on behalf of the Trust.

                                   Section 10
                               Execution of Papers

         Except as the Trustees may generally or in particular  cases  authorize
the  execution  thereof in some other  manner,  all  deeds,  leases,  transfers,
contracts,  bonds, notes, checks, drafts and other obligations made, accepted or
endorsed by the Trust shall be signed, and all transfers of securities  standing
in the name of the Trust shall be  executed,  by the  president or by one of the
vice  presidents or by the  treasurer or by whomsoever  else shall be designated
for that  purpose by the vote of the  Trustees and need not bear the seal of the
Trust.

                                   Section 11
                                   Fiscal Year


         Except as from time to time  otherwise  provided by the  Trustees,  the
fiscal year of the Trust shall end on December 31.



                                   Section 12
                                   Amendments

                              MANAGEMENT AGREEMENT

AGREEMENT dated as of January 18, 2000 between  Colonial  INVESTMENT  GRADE BOND
FUND, a Massachusetts business trust (Fund), and COLONIAL MANAGEMENT ASSOCIATES,
INC., a Massachusetts corporation (Advisor).

In  consideration  of the promises and  covenants  herein,  the parties agree as
follows:

1.      The  Advisor  will  manage the  investment  of the assets of the Fund in
        accordance  with its  investment  policies  and will  perform  the other
        services  herein set forth,  subject to the  supervision of the Board of
        Trustees of the Fund.

2. In carrying out its investment management obligations, the Advisor shall:

        (a) evaluate such economic,  statistical  and financial  information and
        undertake such investment  research as it shall believe  advisable;  (b)
        purchase  and sell  securities  and  other  investments  for the Fund in
        accordance  with the procedures  approved by the Board of Trustees;  and
        (c) report results to the Board of Trustees.

3. The Advisor shall furnish at its expense the following:

        (a) office space, supplies,  facilities and equipment; (b) executive and
        other  personnel  for  managing  the  affairs  of  the  Fund  (including
        preparing financial  information of the Fund and reports and tax returns
        required to be filed with public  authorities,  but  exclusive  of those
        related to  custodial,  transfer,  dividend  and plan  agency  services,
        determination  of net asset value and maintenance of records required by
        Section 31(a) of the Investment Company Act of 1940, as amended, and the
        rules  thereunder  (1940 Act)); and (c) compensation of Trustees who are
        directors,  officers,  partners  or  employees  of  the  Advisor  or its
        affiliated persons (other than a registered investment company).

4.      The Advisor shall be free to render  similar  services to others so long
        as its services hereunder are not impaired thereby.

5.       The Fund shall pay the Advisor monthly a fee at the annual rate of
         0.50% of the Average [Weekly] Managed Assets of the Fund.

       "Average  [Weekly]  Managed  Assets" of the Fund  shall mean the  average
       [weekly]  value  of  the  total  assets  of the  Fund  less  all  accrued
       liabilities  of  the  Fund  (other  than  the  aggregate  amount  of  any
       outstanding borrowings constituting financial leverage).

6.      If the  operating  expenses  of the Fund for any fiscal  year exceed the
        most restrictive  applicable  expense  limitation for any state in which
        shares are sold,  the  Advisor's  fee shall be reduced by the excess but
        not to less than zero.

        Operating  expenses  shall  not  include  brokerage,   interest,  taxes,
        deferred organization  expenses and extraordinary  expenses, if any. The
        Advisor may waive its  compensation  (and, bear expenses of the Fund) to
        the extent that expenses of the Fund exceed any expense  limitation  the
        Advisor declares to be effective.

7.      This Agreement shall become effective as of the date of its execution,
        and

        (a) unless otherwise terminated, shall continue until two years from its
        date of execution  and from year to year  thereafter so long as approved
        annually in accordance with the 1940 Act; (b) may be terminated  without
        penalty on sixty days' written  notice to the Advisor  either by vote of
        the  Board  of  Trustees  of the  Fund or by vote of a  majority  of the
        outstanding  voting  securities  of the Fund;  (c)  shall  automatically
        terminate  in the  event of its  assignment;  and (d) may be  terminated
        without  penalty by the  Advisor on sixty  days'  written  notice to the
        Fund.

8. This Agreement may be amended in accordance with the 1940 Act.

9.      For the purpose of the  Agreement,  the terms "vote of a majority of the
        outstanding  voting  securities",  "affiliated  person" and "assignment"
        shall  have  their  respective  meanings  defined  in the  1940  Act and
        exemptions  and  interpretations  issued by the  Securities and Exchange
        Commission under the 1940 Act.

10.     In the absence of willful misfeasance,  bad faith or gross negligence on
        the part of the Advisor,  or reckless  disregard of its  obligations and
        duties  hereunder,  the Advisor shall not be subject to any liability to
        the Fund, to any shareholder of the Fund or to any other person, firm or

         1.  Appointment.  The Fund  appoints  Distributor  to act as  principal

Shares for each series or class of the Fund set forth on Schedule A hereto.

         2. Delivery of Fund Documents.  The Fund has furnished Distributor with
properly certified or authenticated copies of each of the following in effect on

         (a)      Agreement and Declaration of Trust;

         (b)      By-Laws;

         (c)      Resolutions of the Board of Trustees of the Fund  (hereinafter
                  referred  to  as  the  "Board")   selecting   Distributor   as
                  distributor   and   approving   this  form  of  agreement  and
                  authorizing its execution.

deem necessary or appropriate in the proper performance of its duties.

         3.  Distribution of Shares.

         (a)      Subject to the  provisions  of Paragraphs 6, 7, 10, 11, 12, 13
                  and  14  hereof,  and  to  such  minimum  purchase  and  other
                  requirements  as may  from  time to time be  indicated  in the
                  Fund's  Prospectus,  Distributor,  acting as principal for its
                  own  account  and not as agent  for the Fund,  shall  have the
                  right to purchase Shares from the Fund. Distributor shall sell

                  printing and supplying the currently effective  Prospectus and
                  SAI  to  shareholders,   other  than  those   necessitated  by
                  Distributor's  activities or rules and regulations  related to
                  Distributor's  activities where such amendments or supplements
                  result in  expenses  which the Fund would not  otherwise  have
                  incurred.

         (c)      The  Distributor  (or its  affiliates)  shall pay the costs of
                  printing and  supplying all copies of the  Prospectus  and SAI
                  that it may reasonably  request for use in connection with the
                  distribution  of  Shares.  The  Distributor  will also pay the
                  expenses  of  the  preparation,   excluding  legal  fees,  and
                  printing  of all  amendments  and  supplements  to the  Fund's
                  Prospectus and SAI if the amendment or supplement  arises from
                  Distributor's  activities or rules and regulations  related to
                  Distributor's   activities   and  those   expenses  would  not
                  otherwise have been incurred by the Fund. Distributor will pay
                  all expenses incurred by Distributor in advertising, promoting
                  and selling Fund Shares.

         (d)      Prior  to  the   continuous   offering  of  any  Fund  Shares,
                  commencing  on  a  date  agreed  upon  by  the  Fund  and  the
                  Distributor,  it is  contemplated  that  the  Distributor  may
                  solicit  subscriptions  for such Shares during a  subscription
                  period  which shall last for such period as may be agreed upon
                  by the  parties  hereto.  The  subscriptions  will be  payable
                  within  three  business  days  after  the  termination  of the
                  subscription  period,  at which  time the Fund  will  commence
                  operations.

         4.  Selling  Agreements.   Distributor  is  authorized  to  enter  into
agreements  with  other   broker-dealers   providing  for  the  solicitation  of
unconditional  orders for purchases of the Fund's Shares authorized for issuance
and registered under SA-33 and fix therein the portion of the sales charge which
may be  reallowed  to the  selected  dealers,  as  permitted  under that  Fund's
prospectus.  All such  agreements  shall  be  either  in the  form of  agreement
attached  hereto or in such other form as may be approved by the officers of the
Fund ("Selling  Agreement").  Within the United States,  the  Distributor  shall
offer and sell Shares to such  selected  dealers as are members in good standing
of the NASD;  "banks" as such term is defined in Section 3(a)(6) of the Exchange
Act or a "bank  holding  company"  as such term is defined  in the Bank  Holding
Company Act of 1956, as amended,  duly organized,  validly  existing and in good
standing under the laws of the jurisdiction in which it was organized;  and such
other entities or purchasers as otherwise mutually agreed in writing.

         5. Conduct of Business. Other than as set forth in the Fund's currently
effective  prospectus,  Distributor  will not  distribute  any sales material or
statements  except  literature or advertising which conforms to the requirements
of federal  and state  securities  laws and  regulations  which have been filed,
where necessary,  with the appropriate regulatory  authorities.  Upon the Fund's
request,  Distributor  will  furnish the Fund with copies of all such  materials
prior to their use. Any sales  material or statements  the substance of which is
not included in the Prospectus or SAI shall be submitted for advance approval by
the Fund.

         6.  Solicitation  of Orders to  Purchase  Shares  by Fund.  The  rights
granted to the Distributor  shall be non-exclusive in that the Fund reserves the
right to solicit purchases from, and sell its Shares to, investors. Further, the
Fund  reserves  the  right to issue  Shares  in  connection  with the  merger or
consolidation of any other investment company, trust or personal holding company
with the Fund, or the Fund's acquisition,  by the purchase or otherwise,  of all
or substantially all of the assets of an investment  company,  trust or personal
holding company,  or substantially all of the outstanding Shares or interests of
any such entity. Any right granted to Distributor to solicit purchases of Shares
will not apply to Shares  that may be  offered  by the Fund to  shareholders  by
virtue of their being shareholders of the Fund.

         7. Shares  Covered by this  Agreement.  This  Agreement  relates to the
solicitation  of  orders  to  purchase  Shares  that  are  duly  authorized  and
registered and available for sale by the Fund, including redeemed or repurchased
Shares if and to the extent  that they may be legally  sold and if, but only if,
the Fund authorizes the Distributor to sell them.

         8. Public  Offering  Price.  The public  offering  price for the Fund's
Shares will be the net asset value per Share next  determined  by the Fund after
the  Distributor or its appointed agent receives the order plus any sales charge
as set forth in the Fund's  Prospectus.  The net asset  value per Share shall be
determined in the manner  provided in the Fund's  Agreement and  Declaration  of
Trust as now in effect or as they may be amended, and as reflected in the Fund's
then current Prospectus and SAI.

         9.  Compensation.

         (a)      Sales Charge.  Distributor shall be entitled to charge a sales
                  charge on the sale or redemption,  as appropriate,  of
                  each  series and class of each Fund's  Shares as set forth in
                  the Fund's then  current  Prospectus.  Distributor  may
                  allow any dealers with which it has signed selling  agreements
                  such  commissions or discounts from and not exceeding
                  the total sales charge as  Distributor  shall deem  advisable,
                  so long as any such  commissions or discounts are set
                  forth in the Fund's current  Prospectus to the extent required
                  by the applicable  federal and state  securities laws.
                  Distributor  may  also  make  payments  to  dealers  from
                  Distributor's  own  resources,  subject  to the  following
                  conditions:  (a) any such payments  shall not create any
                  obligation  for or recourse  against the Fund or any series
                  or class,  and (b) the terms and  conditions  of any such
                  payments are  consistent  with the Fund's  Prospectus  and
                  applicable  federal and state  securities laws and are
                  disclosed in the Prospectus or SAI to the extent such laws may
                  require.
<PAGE>   4

         (b)      Distribution  Plans.  Distributor  shall also be  entitled  to
                  compensation  for its services as provided in any Distribution
                  Plan  adopted as to any series and class of any Fund's  Shares
                  pursuant to Rule 12b-1 under the ICA-40.

         10.  Suspension  of Sales.  If and  whenever the  determination  of the
Fund's net asset value is suspended and until such suspension is terminated, the
Distributor shall not accept orders for Shares except for  unconditional  orders
placed  before the  suspension.  In  addition,  the Fund  reserves  the right to
suspend  sales of Shares if, in the judgment of the Board of the Fund,  it is in
the best  interest of the Fund to do so, such  suspension  to continue  for such
period as may be determined by the Board of the Fund; and in that event,  (i) at
the direction of the Fund,  Distributor  shall suspend receipt and acceptance of
orders to purchase Shares of the Fund until otherwise instructed by the Fund and
(ii) the  Distributor  shall not accept  orders to  purchase  Shares  while such
suspension remains in effect unless otherwise directed by the Board.

         11. Orders and Payment for Shares.

         (a)      Distributor  shall direct orders for the purchase of Shares of
                  any series to the Fund's  transfer  agent.  At or prior to the
                  time of  delivery  of any Shares the  Distributor  will pay or
                  cause to be paid to the  custodian of the Fund's  assets,  for
                  the  account  of such  series,  an amount in cash equal to the
                  purchase  price  of such  Shares.  The  Fund's  custodian  and
                  transfer agent shall be identified in its Prospectus.

         (b)      The Fund,  or any agent of the Fund  designated  in writing by
                  the Fund, shall be promptly advised of all purchase orders for
                  Fund  Shares  received  by the  Distributor.  Any order may be
                  rejected by the Fund;  provided,  however,  that the Fund will
                  not arbitrarily or without  reasonable  cause refuse to accept
                  or  confirm  orders  for  the  purchase  of Fund  Shares  from
                  eligible investors.

         12. Repurchase or Redemption of Shares by the Fund.

         (a)      Any of the outstanding  Fund Shares may be tendered to the
                  transfer agent for redemption at any time, other than when
                  the Fund suspends  redemptions as permitted by the Prospectus
                  or applicable law, and the Fund agrees to repurchase or
                  redeem the Shares so tendered in accordance  with its
                  obligations  as set forth in its Agreement and  Declaration of
                  Trust,  as amended from time to time, and in accordance
                  with the  applicable  provisions set forth in the Prospectus
                  and SAI. The price to be paid to redeem or  repurchase  the
                  Shares  shall be equal to the net asset value  calculated
                  in  accordance  with the  provisions of the Fund's  Prospectus
                  and SAI, less any  contingent  deferred  sales charge
                  ("CDSC"),  redemption  fee or other  charge(s),  if any, set
                  forth in the Prospectus or SAI of the Fund. All payments
                  by the Fund hereunder shall be made in the manner set forth
                  below.

         (b)      If Shares are tendered to the transfer agent for redemption or
                  repurchase  by the  Fund  within  seven  business  days  after
                  Distributor's  acceptance of the original  purchase  order for
                  such Shares,  Distributor will immediately  refund to the Fund
                  the full sales  commission  (net of  allowances  to dealers or
                  brokers) allowed to Distributor on the original sale, and will
                  promptly,  upon receipt  thereof,  pay to the Fund any refunds
                  from  dealers or brokers of the  balance of sales  commissions
                  reallowed  by  Distributor.  The  transfer  agent shall notify
                  Distributor of such tender for  redemption  within ten days of
                  the day on which  notice  of such  tender  for  redemption  is
                  received by the transfer agent.

         (c)      The  transfer   agent  shall  pay  the  total  amount  of  the
                  redemption  price as  defined  in the above  paragraph  12(a),
                  pursuant to the  instructions  of the  Distributor  in Federal
                  Funds on or before the seventh  business day subsequent to its
                  having received the notice of redemption in proper form except
                  as otherwise  provided in the  Prospectus  or SAI of the Fund.
                  The proceeds of any  redemption of Shares shall be paid by the
                  transfer agent as follows:  (i) any  applicable  CDSC shall be
                  paid to the Distributor, and (ii) the balance shall be paid to
                  or for  the  account  of the  shareholder,  in  each  case  in
                  accordance with the applicable provision of the Prospectus and
                  SAI.

<PAGE>   5

         13. Purchases for your own Account. Distributor may purchase Shares for
its own  investment  account  upon  Distributor's  written  assurance  that  the
purchase  is for  investment  purposes  and that the  Shares  will not be resold
except through redemption by the Fund.

         14. Stein Roe & Farnham Incorporated Investment Programs. In connection
with any  program  under which  Stein Roe & Farnham  Incorporated  or one of its
affiliates  offers  investment  advice  to  shareholders,   the  Distributor  is
authorized to offer and sell Shares of the Fund, as principal,  to  participants
in such  program.  The  terms  of this  Agreement  shall  apply  to such  sales,
including  terms as to the offering price of Shares,  the proceeds to be paid to
the  Fund,  the  duties  of  the  Distributor,   the  payment  of  expenses  and
indemnification obligations of the Fund and the Distributor.

         15.   Authorized   Representations.   No  Fund  is  authorized  by  the
Distributor to give on behalf of the  Distributor any information or to make any
representations other than the information and representations  contained in the
Fund's registration statement filed with the SEC under SA-33 and/or ICA-40 as it
may be amended from time to time.

         16.  Registration  of  Additional  Shares.  The Fund  hereby  agrees to
register an indefinite  number of Shares pursuant to Rule 24f-2 under ICA-40, as
amended. The Fund will, in cooperation with the Distributor, take such action as
may be  necessary  from time to time to qualify  the Shares  (so  registered  or
otherwise  qualified for sale under SA-33),  in any state mutually  agreeable to
the  Distributor  and the Fund,  and to maintain such  qualification;  provided,
however,  that  nothing  herein  shall  be  deemed  to  prevent  the  Fund  from
registering its Shares without approval of the Distributor in any state it deems
appropriate.

         17. Conformity With Law.  Distributor  agrees that in soliciting orders
to purchase Shares it shall duly conform in all respects with applicable federal
and state laws and the rules and regulations of the NASD.  Distributor  will use
its best efforts to maintain its  registrations in good standing during the term
of this  Agreement  and will  promptly  notify the Fund and Colonial  Management
Associates,  Inc. in the event of the  suspension or  termination  of any of the
registrations.

         18.  Independent  Contractor.   Distributor  shall  be  an  independent
contractor  and neither the  Distributor,  nor any of its  officers,  directors,
employees,  or  representatives  is or shall be an  employee  of the Fund in the
performance of Distributor's duties hereunder.  Distributor shall be responsible
for its own conduct and the employment,  control,  and conduct of its agents and
employees  and for injury to such agents or employees  or to others  through its
agents  and  employees  and  agrees  to  pay  all  employee  taxes   thereunder.
Distributor may appoint sub-agents or distribute through dealers or otherwise as
Distributor  may determine from time to time,  but this  Agreement  shall not be
construed as authorizing any dealer or other person to accept orders for sale or
repurchase  on the Fund's  behalf or  otherwise  act as the Fund's agent for any
purpose.

         19. Indemnification.  Distributor agrees to indemnify and hold harmless
the Fund and each of the members of its Board and its  officers,  employees  and
representatives  and each  person,  if any,  who  controls  the Fund  within the
meaning of Section 15 of SA-33 against any and all losses, liabilities, damages,
claims  and  expenses  (including  the  reasonable  costs  of  investigating  or
defending any alleged loss,  liability,  damage, claim or expense and reasonable
legal counsel fees  incurred in connection  therewith) to which the Fund or such
of the members of its Board and of its officers, employees,  representatives, or
controlling  person or persons may become  subject under SA-33,  under any other
statute,  at common  law,  or  otherwise,  arising  out of or based upon (i) any
violation  of  an  applicable  law,  rule  or  regulation  or  wrongful  act  by
Distributor  or  any  of  Distributor's   directors,   officers,   employees  or
representatives,  or (ii) any untrue  statement or alleged untrue statement of a
material  fact  contained  in  a  registration   statement,   Prospectus,   SAI,
shareholder  report or other  information  covering  Shares of the Fund filed or
made public by the Fund or any amendment  thereof or  supplement  thereto or the
omission or alleged  omission to state  therein 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 to
the Fund by Distributor in writing. In no case (i) is Distributor's indemnity in
favor of the Fund, or any person  indemnified,  to be deemed to protect the Fund
or such  indemnified  person  against  any  liability  to which the Fund or such
person would otherwise be subject by reason of willful  misfeasance,  bad faith,
or negligence in the performance of its or his duties or by reason of its or his
reckless  disregard of its or his obligations and duties under this Agreement or
(ii) is Distributor to be liable under its indemnity agreement contained in this
paragraph  with  respect  to any  claim  made  against  the  Fund or any  person
indemnified  unless  the Fund or such  person,  as the case may be,  shall  have
notified  Distributor in writing of the claim within a reasonable time after the
summons, or other first written  notification,  giving information of the nature
of the claim served upon the Fund or upon such person (or after the Fund or such
person  shall have  received  notice of such service on any  designated  agent).
However,  failure  to notify  Distributor  of any such claim  shall not  relieve
Distributor  from any liability  which  Distributor  may have to the Fund or any
person  against  whom such  action  is  brought  otherwise  than on  account  of
Distributor's indemnity agreement contained in this Paragraph.

<PAGE>   6

         Distributor  shall be entitled to participate,  at its own expense,  in
the defense,  or, if  Distributor  so elects,  to assume the defense of any suit
brought to  enforce  any such claim  but,  if  Distributor  elects to assume the
defense,  such defense shall be conducted by legal counsel chosen by Distributor
and  satisfactory to the persons  indemnified who are defendants in the suit. In
the event that  Distributor  elects to assume  the  defense of any such suit and
retain such legal counsel,  persons  indemnified  who are defendants in the suit
shall bear the fees and expenses of any  additional  legal  counsel  retained by
them.  If  Distributor  does not elect to assume  the  defense of any such suit,
Distributor will reimburse  persons  indemnified who are defendants in such suit
for  the  reasonable  fees  of any  legal  counsel  retained  by  them  in  such
litigation.

         The Fund agrees to indemnify and hold harmless  Distributor and each of
its directors, officers, employees, and representatives and each person, if any,
who controls  Distributor  within the meaning of Section 15 of SA-33 against any
and all losses, liabilities,  damages, claims or expenses (including the damage,
claim or expense and  reasonable  legal  counsel  fees  incurred  in  connection
therewith) to which Distributor or such of its directors,  officers,  employees,
representatives or controlling person or persons may become subject under SA-33,
under any other  statute,  at common law, or  otherwise  arising out of or based
upon (i) any violation of applicable  law, rule or regulation or wrongful act by
the Fund or any of the  members of the  Fund's  Board,  or the Fund's  officers,
employees  or  representatives  other  than  Distributor,  or  (ii)  any  untrue
statement  or  alleged  untrue  statement  of a  material  fact  contained  in a
registration statement, Prospectus, SAI, shareholder report or other information
covering  Shares  filed or made public by the Fund or any  amendment  thereof or
supplement  thereto,  or the  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading  unless such  statement or omission was made in reliance
upon  information  furnished by  Distributor  to the Fund. In no case (i) is the
Fund's  indemnity in favor of the  Distributor  or any person  indemnified to be
deemed to  protect  the  Distributor  or such  indemnified  person  against  any
liability to which  Distributor or such  indemnified  person would  otherwise be
subject  by reason of  willful  misfeasance,  bad faith,  or  negligence  in the
performance  of its or his duties or by reason of its or his reckless  disregard
of its or his obligations  and duties under this Agreement,  or (ii) is the Fund
to be liable under its  indemnity  agreement  contained in this  Paragraph  with
respect to any claim made against  Distributor or any person  indemnified unless
Distributor, or such person, as the case may be, shall have notified the Fund in
writing of the claim within a reasonable time after the summons,  or other first
written notification,  giving information of the nature of the claim served upon
Distributor or upon such person (or after  Distributor or such person shall have
received notice of such service on any designated  agent).  However,  failure to
notify a Fund of any such claim shall not  relieve  the Fund from any  liability
which the Fund may have to Distributor or any person against whom such action is
brought otherwise than on account of the Fund's indemnity agreement contained in
this Paragraph.

         The Fund shall be entitled to participate,  at its own expense,  in the
defense or, if the Fund so elects,  to assume the defense of any suit brought to
enforce such claim but, if the Fund elects to assume the  defense,  such defense
shall be conducted by legal counsel chosen by the Fund and  satisfactory  to the
persons  indemnified  who are defendants in the suit. In the event that the Fund
elects to assume the defense of any such suit and retain such legal counsel, the
persons  indemnified  who are  defendants  in the suit  shall  bear the fees and
expenses of any additional  legal counsel retained by them. If the Fund does not
elect to assume  the  defense  of any such  suit,  the Fund will  reimburse  the
persons  indemnified who are defendants in such suit for the reasonable fees and
expenses of any legal counsel retained by them in such litigation.

         20.  Duration and  Termination of this  Agreement.  With respect to the
Fund  and the  Distributor,  this  Agreement  shall  become  effective  upon its
execution  ("Effective  Date") and unless  terminated as provided herein,  shall
remain in effect  through June 30, 2001, and from year to year  thereafter,  but
only so long as such continuance is specifically  approved at least annually (a)
by a vote of  majority  of the  members  of the  Board  of the  Fund who are not
interested  persons  of the  Distributor  or of the Fund,  voting in person at a
meeting called for the purpose of voting on such  approval,  and (b) by the vote
of either the Board of the Fund or a majority of the  outstanding  Shares of the
Fund.  This  Agreement may be  terminated by and between an individual  Fund and
Distributor  at any time,  without  the  payment of any  penalty (a) on 60 days'
written  notice,  by the  Board  of the Fund or by a vote of a  majority  of the
outstanding  Shares of the  Fund,  or by  Distributor,  or (b)  immediately,  on
written  notice  by the  Board  of the  Fund,  in the  event of  termination  or
suspension  of any of  the  Registrations.  This  Agreement  will  automatically
terminate in the event of its assignment. In interpreting the provisions of this
Paragraph 20 the definitions  contained in Section 2(a) of ICA-40  (particularly
the  definitions  of  "interested  person",  "assignment",  and "majority of the
outstanding Shares") shall be applied.

         21. Amendment of this Agreement.  No provision of this Agreement may be
changed, waived,  discharged, or terminated orally, but only by an instrument in
writing signed by each party against which  enforcement  of the change,  waiver,
discharge,  or  termination  is sought.  If the Fund  should at any time deem it
necessary or advisable in the best  interests of the Fund that any  amendment of
this  Agreement  be  made  in  order  to  comply  with  the  recommendations  or
requirements  of the SEC or any other  governmental  authority  or to obtain any
advantage  under state or Federal tax laws and notifies  Distributor of the form
of such amendment,  and the reasons therefor,  and if Distributor should decline
to assent to such amendment, the Fund may terminate this Agreement forthwith. If
Distributor  should  at any time  request  that a change  be made in the  Fund's
Agreement  and  Declaration  of  Trust or  By-Laws  or in its  methods  of doing
business, in order to comply with any requirements of Federal law or regulations
of the SEC, or of a national  securities  association of which Distributor is or
may be a member,  relating  to the sale of Shares,  and the Fund should not make
such necessary changes within a reasonable time,  Distributor may terminate this
Agreement forthwith.

         22. Liability.  It is understood and expressly  stipulated that neither
the  shareholders  of the Fund nor the members of the Board of the Fund shall be
personally  liable  hereunder.  The  obligations  of the Fund are not personally
binding upon, nor shall resort to the private property of, any of the members of
the Board of the Fund, nor of the shareholders, officers, employees or agents of
the Fund, but only the Fund's property shall be bound. A copy of the Declaration
of Trust and of each  amendment  thereto  has been  filed by the Trust  with the
Secretary of State of The  Commonwealth of  Massachusetts  and with the Clerk of
the City of Boston, as well as any other  governmental  office where such filing
may from time to time be required.

         23.  Miscellaneous.  The  captions in this  Agreement  are included for
convenience  or  reference  only,  and  in no way  define  or  limit  any of the
provisions  hereof or  otherwise  affect  their  construction  or  effect.  This
Agreement may be executed  simultaneously in two or more  counterparts,  each of

                            LIBERTY FUNDS TRUST I-IX
             LIBERTY-STEIN ROE ADVISOR FLOATING RATE ADVANTAGE FUND
                      COLONIAL INVESTMENT GRADE BOND FUND
   Plan pursuant to Rule 18f-3(d) under the Investment Company Act of 1940

                          Effective April 22, 1996(1)
                            Amended November 1, 1999

Each series ("Fund") of Liberty Funds Trusts I-IX (the "Trusts") may from time
to time issue one or more of the following classes of shares: Class A shares,
Class B shares, Class C shares, Class E shares, Class F shares, Class G shares,
Class H shares, Class I shares, Class J shares, Class T shares, Class S shares
and Class Z shares. Each class is subject to such investment minimums  and
other conditions of eligibility as set forth in the Funds' prospectuses as from
time to time in effect. The differences in expenses among these classes of
shares, and the conversion and exchange features of each class of shares, are
set forth below in this Plan, which is subject to change, to the extent
permitted by law and by the Declaration of Trust and By-laws of each Trust, by
action of the Board of Trustees of each Trust.

Class A shares

Class A shares are offered at net asset value ("NAV") plus the initial sales
charges described in the Funds' prospectuses as from time to time in effect.
Initial sales charges may not exceed 6.50%, and may be reduced or waived as
permitted by Rule 22d-1 under the Investment Company Act of 1940 (the "1940
Act") and as described in the Funds' prospectuses from time to time in effect.

Purchases of $1 million to $5 million of Class A shares that are redeemed
within 18 months form purchase are subject to a contingent deferred sales
charge ("CDSC") of 1% of either the purchase price or the NAV of the shares
redeemed, whichever is less. Class A shares are not otherwise subject to a
CDSC. The CDSC may be reduced or waived as permitted by Rule 6c-10 under the
1940 Act and as described in the Funds' prospectuses as from time to time in
effect.

Class A shares pay service fees pursuant to plans adopted pursuant to Rule
12b-1 under the 1940 Act ("12b-1 Plans") as described in the Funds'
prospectuses in effect from time to time. Such fees may not exceed 0.25% per
annum of the average daily net assets attributable to such class. Class A
shares generally do not pay distribution fees, except that Colonial Strategic
Balanced Fund pays a distribution fee of 0.30% per annum of average daily net
assets attributable to its Class A shares.

Class A shares of any Fund may be exchanged, at the holder's option, for Class
A shares of another Fund without the payment of a sales charge, except that if
shares of any other non-money market fund are exchanged within five months
after purchase for shares of a Fund with a higher sales charge, then the
difference in sales charges must be paid on the exchange.

Class B shares

Class B shares are offered at NAV, without an initial sales charge, Class B
shares that are redeemed within the period of time after purchase (not more
than 6 years) specified in each Fund's prospectus as from time to time in
effect are subject to a CDSC of up to 5% of either the purchase price or the
NAV of the shares redeemed, whichever is less; such percentage may be lower
for certain Funds and declines the longer the shares are held, all as described
in the Funds' prospectuses as from time to time in effect. Class B shares
purchased with reinvested distributions are not subject to a CDSC. The CDSC is
subject to
<PAGE>   2
reduction, or waiver in certain circumstances, as permitted by Rule 6c-10 under
the 1940 Act and as described in the Funds' prospectuses as from time to time in
effect.

Class B shares pay distribution and service fees pursuant to 12b-1 Plans as
described in the Funds' prospectuses in effect from time to time. Such fees may
be in amounts up to but may not exceed, respectively, 0.75% and 0.25% per annum
of the average daily net assets attributable to such class.

Class B shares automatically convert to Class A shares of the same Fund eight
years after purchase, except that Class B shares purchased through the
reinvestment of dividends and other distributions on Class B shares convert
proportionally to the amount of Class B shares otherwise being converted.

Class B shares of any Fund may be exchanged, at the holder's option, for Class B
shares of another Fund, without the payment of a CDSC. The holding period for
determining the CDSC and the conversion to Class A shares will include the
holding period of the shares exchanged. If the Class B shares received in the
exchange are subsequently redeemed, the amount of the CDSC, if any, will be
determined by the schedule of the Fund in which the original investment was
made.

Class C shares

Class C shares are offered at NAV without an initial sales charge. Class C
shares that are redeemed within one year from purchase may be subject to a CDSC
of 1% of either the purchase price or the NAV of the shares redeemed, whichever
is less. Class C shares purchased with reinvested dividends or capital gain
distributions are not subject to a CDSC. The CDSC may be reduced or waived in
certain circumstances as permitted by Rule 6c-10 under the 1940 Act and as
described in the Funds' prospectuses as from time to time in effect.

Class C shares pay distribution and service fees pursuant to 12b-1 Plans, as
described in the Funds' prospectuses in effect from time to time. Such fees may
be in amounts up to but may not exceed, respectively, 0.75% and 0.25% per annum
of the average daily net assets attributable to such class.

Class C shares of any Fund may be exchanged for Class C shares of any other Fund
that offers Class C shares. The holding period for determining whether a CDSC
will be charged will include the holding period of the shares exchanged. Only
one exchange of any Fund's Class C shares may be made in any three month period.
For this purpose, an exchange into any Fund and a prior or subsequent exchange
out of the Fund constitutes "one exchange."

Class E shares

Class E shares are offered at NAV plus the initial sales charges described in
the Fund's prospectus as from time to time in effect. Initial sales charges may
not exceed 5.00%, and may be reduced or waived as permitted by Rule 22d-1 under
the 1940 Act and as described in the Fund's prospectus from time to time in
effect.

Purchases of $1 million to $5 million of Class E shares that are redeemed within
18 months from purchase are subject to the same CDSC on the same basis as Class
A shares. Class E shares are not otherwise subject to a CDSC. The CDSC may be
reduced or waived as permitted by Rule 6c-10 under the 1940 Act and as described

                            [ROPES & GRAY LETTERHEAD]



                                                                January 13, 2000




Colonial Investment Grade Bond Fund
One Financial Center
Boston, Massachusetts 02111

Ladies and Gentlemen:

         We have acted as counsel to Colonial Investment Grade Bond Fund (the
"Fund") in connection with the Registration Statement of the Fund on Form N-2
(File Nos. 333-91385 and 811-9701) (the "Registration Statement") under the
Securities Act of 1933 and the Investment Company Act of 1940, each as amended
(the "Acts"), relating to the proposed sale of the Fund's Class A shares, Class
B shares, Class C shares and Class Z shares (the "Shares").

         We have examined the Fund's Agreement and Declaration of Trust on file
in the office of the Secretary of State of the Commonwealth of Massachusetts, as
amended (the "Declaration of Trust"), and the Fund's By-Laws (the "By-Laws"),
and are familiar with the actions taken by the Trustees of the Fund in
connection with the issuance and sale of the Shares. We have also examined such
other documents and records as we have deemed necessary for the purposes of this
opinion.

         Based upon the foregoing, we are of the opinion that:

         1.       The Fund is a duly organized and validly existing
                  unincorporated association under the laws of the Commonwealth
                  of Massachusetts.


         2.       An unlimited number of the Fund's Shares has been duly
                  authorized and, when such authorized but unissued Shares are
                  issued and paid for in accordance with the Underwriting
                  Agreement filed as an exhibit to the Registration Statement,
                  they will be validly issued, fully paid and nonassessable by
                  the Fund.



         The Fund is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Fund.
However, the Declaration of Trust disclaims shareholder liability for acts or
obligations of the Fund and requires that a notice of such disclaimer be given
in each note, bond, contract, instrument, certificate or undertaking entered
into or executed by the Fund or its Trustees. The Declaration of Trust provides
for indemnification out of the property of each series of the Fund for all loss
and expense of any shareholder of


<PAGE>   2

Colonial Investment Grade Bond Fund       -2-                  January 13, 2000

such series of the Fund held personally liable solely by reason of the
shareholder's being or having been a shareholder. Thus, the risk of a
shareholder incurring financial loss on account of being a shareholder is
limited to circumstances in which the series of the Fund itself would be unable
to meet its obligations.

         We understand that this opinion is to be used in connection with the
registration of the Shares for offering and sale pursuant to the Acts. We
consent to the filing of this opinion with and as part of the Registration
Statement.


                                             Very truly yours,


                                             /s/ ROPES & GRAY

               CONSENT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



We consent to the reference to our firm under the caption "Independent Auditors"
in the Statement of Additional Information and to the use of our report dated
January 13, 2000, with respect to the financial statement of the Colonial
Investment Grade Bond Fund included in this Pre-Effective Amendment No. 1 to the
Registration Statement (Form N-2, Registration No. 333-91385).
