                "Manager" or "Heritage"),  voluntarily  will waive its fees and,
                if  necessary,  reimburse  the Fund to the  extent  that Class A
                annual operating  expenses exceed 1.65% of the average daily net
                assets  and to the  extent  that  Class  B and  Class  C  annual

                EXAMPLES OF THE EFFECT OF FUND EXPENSES:

                    The  impact  of  Fund  operating  expenses  on  earnings  is
                illustrated in the examples below assuming a hypothetical $1,000
                investment and a 5% annual rate of return.

                                                 1 YEAR 3 YEARS

                 Class B shares (assuming sale      
                  of all shares at end of
                  period) ......................    $74       $105

                 Class C shares.................    $24        $75

                    This is an illustration  only and should not be considered a
                representation   of  future   expenses.   Actual   expenses  and
                performance  may be greater or less than that shown  above.  The
                purpose  of  the  above   tables  is  to  assist   investors  in
                understanding  the various costs and expenses that will be borne
                directly or indirectly by shareholders. Due to the imposition of
                Rule 12b-1 fees, it is possible that long-term  shareholders  of
                the Fund may pay more in total sales  charges  than the economic
                equivalent of the maximum  front-end sales load permitted by the
                rules of the National  Association of Securities  Dealers,  Inc.

MONEY BY        
INVESTING IN        Eagle will pursue a flexible   investment  strategy  in  the
THE FUND.       selection  of  equity  securities  of growth  companies.  Growth
                companies frequently are characterized by above-average earnings
                or sales growth and retention of earnings.  In addition,  growth
                companies often command higher price to earnings ratios than the
                securities  of  other  companies.  They are not  limited  to any
                particular investment sector, industry or company size.         
                
                    While Eagle believes that the growth  companies in which the
                Fund   invests   offer   greater   opportunities   for   capital
                appreciation  than that of the market  averages,  investment  in
                growth  companies  entails  significant  risks  that you  should
                consider  before   investing.   The  prices  of  growth  company
                securities  may rise and fall  dramatically  based,  in part, on
                investors' perceptions of the company rather than on fundamental
                analysis of the securities.  Investing in growth  companies also
                may  involve  more  risk  because  these  companies  may have no
                earnings or have experienced losses. In certain cases, Eagle may
                identify a company as a growth  company  based on a belief  that
                actual or  anticipated  products or services will produce future
                earnings.  If the  company  fails to realize  these  products or
                services,  the price of its securities  may decline  sharply and
                become less liquid.

                    The Fund will invest,  under normal  market  conditions,  at
                least 65% of its  total  assets  in  equity  securities.  Equity
                securities in which the Fund may invest  include  common stocks,

                preferred  stocks,  securities  convertible  into either  common
                stock or preferred  stock,  and warrants and rights  exercisable
                for  equity  securities.  The Fund also may  invest in  American
                Depository  Receipts  ("ADRs") and Real Estate Investment Trusts
                ("REITs"). The Fund may invest the remainder of its total assets
                in U.S. Government  securities,  repurchase  agreements or other
                short-term money market instruments.

INVESTING IN        The Fund  will  invest a  majority  of its  assets in equity
SMALL AND       securities of small and medium size companies, although the Fund
MEDIUM SIZE     may  invest a  portion  of its  assets in  securities  of larger
COMPANIES MAY   corporations that it believes have significant growth potential.
INVOLVE SPECIAL While  small  and  medium  size  companies  generally  may  have
OPPORTUNITIES   potential  for rapid  growth,  these  investments  often involve
AND RISKS.      greater  risks  than  investments  in larger,  more  established
                companies  because  small  and  medium  companies  may  lack the
                management    experience,     financial    resources,    product
                diversification and competition strengths of larger companies.

                    The Fund may  invest up to 10% of its net  assets in foreign
                securities (including depository receipts).  The Fund may invest
                in other investment  companies,  including index securities such
                as Standard & Poor's  Depositary  Receipts and Standard & Poor's
                MidCap 400 Depositary  Receipts.  The Fund also may invest up to
                15% of its net  assets  in  illiquid  securities.  The  Fund may
                purchase or sell a security without regard to the length of time
                the  security  will be or has been held.  Although the Fund will
                not  trade  primarily  for  short-term   profits,  it  may  make
                investments with potential for short-term appreciation when such
                action is deemed desirable and in the best interest of the Fund.
                For a discussion of these investments, see the SAI.

                    The Fund's  investment  objective is fundamental and may not
                be changed  without  the vote of a majority  of the  outstanding
                voting  securities  of the Fund,  as defined  in the  Investment
                Company  Act of 1940,  as amended  (the "1940  Act").  Except as
                otherwise  noted,  all  policies of the Fund  described  in this
                Prospectus  may be  changed  by the  Board of  Trustees  without
                shareholder approval. The SAI contains more detailed information
                about the Fund's investment policies and risks.

                    Following is  description  of the  significant  policies and
                risk factors that are applicable to the Fund:

                    AMERICAN DEPOSITORY  RECEIPTS.  The Fund may invest in ADRs,
                which  typically  are issued by a U.S. bank or trust company and
                evidence  ownership  of the  underlying  securities  of  foreign
                issuers. Generally, ADRs are denominated in U.S. dollars and are
                designed for use in the U.S.  securities  markets.  Thus,  these
                securities  are not  denominated  in the  same  currency  as the
                securities into which they may be converted. ADRs are subject to
                many of the risks  inherent in investing in foreign  securities,
                as described below.  For a further  discussion of ADRs and other
                types of depository receipts, see the SAI.

                    CONVERTIBLE  SECURITIES;  RISK OF  INVESTMENT IN LOWER RATED
                CONVERTIBLE  SECURITIES.  The Fund  may  invest  in  convertible
                securities rated investment grade and up to 5% of its net assets
                in  convertible  securities  rated  below  investment  grade.  A
                convertible security is a bond, debenture, note, preferred stock
                or other  security that may be converted into or exchanged for a
                prescribed  amount  of common  stock of the same or a  different
                issue within a particular period of time at a specified price or
                formula.  A convertible  security entitles the holder to receive
                interest paid or accrued on debt or dividends  paid on preferred
                stock  until  the  convertible  stock  matures  or is  redeemed,
                converted  or  exchanged.  Convertible  securities  have  unique
                investment  characteristics  in that they  generally have higher
                yields  than common  stocks,  but lower  yields than  comparable
                nonconvertible  securities,  are less subject to  fluctuation in
                value than the underlying  stock because they have  fixed-income


                                     Page 3
<PAGE>




                characteristics   and   provide   the   potential   for  capital
                appreciation if the market price of the underlying  common stock
                increases.

                    Investment grade securities  include securities rated BBB or
                above by  Standard & Poor's  ("S&P") or Baa by Moody's  Investor
                Services  ("Moody's")  or,  if  unrated,  are  deemed  to  be of
                comparable  quality by the Subadviser.  Securities  rated in the
                lowest  category  of  investment  grade are  considered  to have
                speculative  characteristics  and changes in economic conditions
                are more likely to lead to a weakened  capacity to pay  interest
                and repay  principal  than is the case with higher  grade bonds.
                The Fund may retain a security  that has been  downgraded  below
                investment grade if, in the opinion of the Subadviser,  it is in
                the Fund's best interest.

                    As  described  above,  the Fund may  invest  in  convertible
                securities rated below  investment  grade by S&P or Moody's,  or
                unrated  convertible  securities  deemed to be below  investment
                grade by the  Subadviser.  The price of  lower-rated  securities
                tends to be less  sensitive  to interest  rate  changes than the
                price of higher-rated securities,  but more sensitive to adverse
                economic   changes   or   individual   corporate   developments.
                Securities  rated  below  investment  grade  are  deemed  to  be
                predominantly  speculative with respect to the issuer's capacity
                to pay interest and repay  principal  and may involve major risk
                exposure to adverse conditions.  See the SAI for a discussion of
                the risks  associated  with  investment  grade  and  lower-rated
                securities  and the Appendix to the SAI for a description of S&P
                and Moody's corporate bond ratings.

                    Lower-rated   securities  (commonly  referred  to  as  "junk
                bonds")  generally  offer  a  higher  current  yield  than  that
                available  for   higher-grade   issues.   However,   lower-rated
                securities  involve  higher risks,  in that they are  especially
                subject to adverse changes in general economic conditions and in
                the  industries in which the issuers are engaged,  to changes in
                the financial condition of the issuers and to price fluctuations
                in  response  to changes in interest  rates.  During  periods of
                economic  downturn or rising  interest rates,  highly  leveraged
                issuers  may  experience  financial  stress  that  could  affect
                adversely  their  ability  to  make  payments  of  interest  and
                principal and increase the possibility of default.  In addition,
                the market for lower rated  securities  has expanded  rapidly in
                recent  years,  and  its  growth   paralleled  a  long  economic
                expansion.  The market for lower-rated  securities  generally is
                thinner and less active than that for higher-quality securities,
                which may limit the Fund's  ability to sell such  securities  at
                fair value in response  to changes in the  economy or  financial
                markets. Adverse publicity and investor perceptions,  whether or
                not based on fundamental analysis,  also may decrease the values
                and liquidity of lower-rated securities,  especially in a thinly
                traded market.

                    FOREIGN   SECURITIES.   The  Fund  may   invest  in  foreign
                securities.  Investments  in securities of foreign  issuers,  or
                securities  principally  traded  overseas,  may involve  certain
                special  risks  due to  foreign  economic,  political  and legal
                developments,  including  favorable  or  unfavorable  changes in
                currency   exchange   rates,   exchange   control   regulations,
                expropriation  of  assets  or  nationalization,   imposition  of
                withholding taxes on dividend or interest payments, and possible
                difficulty in obtaining and enforcing  judgments against foreign
                entities. Furthermore, foreign issuers are subject to different,
                often less comprehensive,  accounting,  reporting and disclosure
                requirements  than  domestic  issuers.  The  securities  of some
                foreign companies and foreign securities markets are less liquid
                and at times more  volatile than  securities of comparable  U.S.
                companies  and  U.S.  securities   markets.   Foreign  brokerage
                commissions  and other fees  generally  are  higher  than in the
                United   States.   Foreign   settlement   procedures  and  trade
                regulation  may involve  certain risks (such as delay in payment
                or  delivery  of  securities  or in the  recovery of assets held
                abroad) and expenses not present in the  settlement  of domestic
                investments.  There also are  special  tax  considerations  that
                apply to foreign currency denominated securities.

                    REAL ESTATE INVESTMENT TRUSTS. The Fund may invest in REITs,
                including equity REITs,  which own real estate  properties,  and
                mortgage  REITs,  which  make   construction,   development  and
                long-term  mortgage  loans.  The value of an equity  REIT may be
                affected  by  changes in the value of the  underlying  property,
                while a  mortgage  REIT may be  affected  by the  quality of the
                credit extended.  The performance of both types of REITs depends
                upon conditions in the real estate industry,  management  skills
                and the amount of cash  flow.  The risks  associated  with REITs
                include  defaults  by  borrowers,  self-liquidation,  failure to
                qualify as a  pass-through  entity  under the  Federal  tax law,
                failure to qualify as an exempt  entity  under the 1940 Act, and
                the fact that REITs are not diversified.

                    REPURCHASE  AGREEMENTS.  The Fund may  invest in  repurchase
                agreements.  Repurchase agreements are transactions in which the
                Fund  purchases  securities and commits to resell the securities
                to the  original  seller (a member bank of the  Federal  Reserve
                System or  securities  dealers  who are  members  of a  national
                securities  exchange  or are  market  makers in U.S.  Government
                securities) at an agreed upon date and price reflecting a market
                rate of interest unrelated to the coupon rate or maturity of the
                purchased  securities.   Although  repurchase  agreements  carry
                certain  risks  not   associated   with  direct   investment  in
                securities,  including  possible declines in the market value of
                the  underlying  securities  and delays and costs to the Fund if
                the other party becomes bankrupt, the Fund intends to enter into
                repurchase   agreements   only  with   banks  and   dealers   in
                transactions  believed  by the  Subadviser  to  present  minimal

                    TEMPORARY  DEFENSIVE   PURPOSES.   For  temporary  defensive
                purposes during  anticipated  periods of general market decline,
                the Fund may invest up to 100% of its net assets in money market
                instruments, including securities issued by the U.S. Government,
                its  agencies or  instrumentalities  and  repurchase  agreements
                secured  thereby,  as well as bank  certificates  of deposit and
                banker's  acceptances  issued by banks  having  net assets of at
                least $1 billion as of the end of their most recent fiscal year,
                high-grade commercial paper, and other long- and short-term debt
                instruments that are rated A or higher by S&P or Moody's.  For a
                description  of S&P or Moody's  commercial  paper and  corporate

                NET ASSET VALUE
                ================================================================

THE NET ASSET       The net asset value of the Fund's shares  fluctuates  and is
VALUE OF THE    determined  separately for each class as of the close of regular
FUND'S SHARES   trading  -  normally  4:00 p.m.  Eastern  time - of the New York
IS CALCULATED   Stock Exchange  ("Exchange") each day it is open. The Fund's net
DAILY AS OF     asset value per share is calculated by dividing the value of the
THE CLOSE OF    total  assets,  less  liabilities,  by the total  number of Fund
REGULAR         shares outstanding.  The per share net asset value of each class
TRADING ON THE  of shares may differ as a result of the different  daily expense
NEW YORK STOCK  accruals applicable to that class.                              
EXCHANGE.       
                    The Fund values its  securities  and other  assets  based on
                their  market value based on the last sales price as reported by
                the principal  securities  exchange on which the  securities are
                traded.  If no sale is  reported,  market  value is based on the
                most  recent  quoted  bid  price.  In the  absence  of a readily
                available  market quote, or if the Manager or the Subadviser has
                reason  to  question  the  validity  of  market   quotations  it
                receives,  securities  and other  assets are  valued  using such
                methods as the Board of Trustees  believes  would  reflect  fair
                value.  Short-term  investments  that will  mature in 60 days or
                less are valued at amortized  cost,  which  approximates  market
                value.  Securities that are quoted in a foreign currency will be

                valued daily in U.S.  dollars at the foreign  currency  exchange
                rate  prevailing at the time the Fund  calculates  its net asset
                value per share.

                    Trading in foreign  markets  is usually  completed  each day
                prior to the close of the  Exchange.  However,  events may occur
                that affect the values of such securities and the exchange rates
                between  the time of  valuation  and the close of the  Exchange.
                Should  events  materially  affect the value of such  securities
                during the period,  the securities are priced at fair value,  as
                determined in good faith and pursuant to procedures  approved by
                the Board.

                PERFORMANCE INFORMATION
                ================================================================

                    Total  return  data of each  class  from time to time may be
                included   in   advertisements   about  the  Fund.   Performance
                information is computed  separately for each class in accordance
                with the methods  described  below.  Because  Class B shares and
                Class C shares bear higher Rule 12b-1 fees,  the  performance of
                Class B shares  and  Class C shares of the Fund  likely  will be
                lower than that of Class A shares.

                    Total return with respect to a class for the one-, five- and
                ten-year  periods or, if such periods have not yet elapsed,  the
                period since the  establishment  of that class  through the most
                recent calendar quarter represents the average annual compounded
                rate of return on an  investment  of $1,000 in that class at the
                public  offering  price (in the case of Class A  shares,  giving
                effect to the  maximum  initial  sales load of 4.75% and, in the
                case of Class B shares and Class C shares,  giving effect to the
                deduction of any  contingent  deferred  sales load ("CDSL") that
                would be payable). In addition, the Fund may advertise its total
                return in the same manner,  but without  taking into account the
                initial sales load or CDSL.  The Fund also may  advertise  total
                return  calculated  without  annualizing  the return,  and total
                return may be presented for other  periods.  By not  annualizing
                the returns,  the total return  calculated in this manner simply
                will  reflect the increase in net asset value per Class A share,
                Class B share and Class C share over a period of time,  adjusted
                for dividends and other  distributions.  Class A share,  Class B
                share and Class C share performance may be compared with various
                indices.

                    All data is based on the Fund's past investment  results and
                does not predict  future  performance.  Investment  performance,
                which  will vary,  is based on many  factors,  including  market
                conditions,  the composition of the Fund's investment  portfolio
                and the Fund's operating expenses.  Investment  performance also
                often reflects the risks  associated with the Fund's  investment
                objective and policies.  These factors should be considered when
                comparing the Fund's investment results to those of other mutual
                funds and other investment vehicles.

                CHOOSING A CLASS OF SHARES
                ================================================================

                     The Fund offers  three  classes of shares,  Class A shares,
                Class B shares and Class C shares.  The primary difference among
                these  classes lies in their sales load  structures  and ongoing
                expenses.

                .    CLASS A SHARES.  Class A shares may be purchased at a price
                     equal to their net asset  value per share  next  determined
                     after  receipt  of an order,  plus a maximum  sales load of
                     4.75%  imposed at the time of purchase.  No CDSL is charged
                     for Class A shares.  Ongoing  Rule  12b-1  fees for Class A
                     shares are lower than the ongoing Rule 12b-1 fees for Class
                     B shares and Class C shares.

                .    CLASS B  SHARES.  Class B shares  may be  purchased  at net
                     asset value with no initial sales charge. As a result,  the
                     entire  amount of your  purchase is  invested  immediately.
                     Class B shares  are  subject to higher  ongoing  Rule 12b-1
                     fees  than  Class A  shares.  A  maximum  CDSL of 5% may be
                     imposed on  redemptions  of Class B shares  made within six
                     years  of  purchase.  After  eight  years,  Class B  shares
                     convert to Class A shares,  which have lower  ongoing  Rule

                    If you purchase  sufficient  shares to qualify for a reduced
                sales load,  you may prefer to purchase  Class A shares  because
                similar  reductions  are not  available for purchases of Class B
                shares or Class C shares.  For example,  if you intend to invest
                more than  $1,000,000 in the Fund,  you should  purchase Class A
                shares to take advantage of the sales load waiver.

                    Financial  Advisors may receive  different  compensation for
                sales of Class A shares  than sales of Class B shares or Class C

                     The CDSL  imposed  depends  on the  amount of time you have

                knowingly  permit the  purchase  of Class A shares  through  the
                Systematic  Investment  Plan if you are at the same time  making
                systematic  withdrawals of Class A shares.  The Manager reserves

                transactions  whose sole purpose is to transfer a  shareholder's
                interest in the Fund to his defined  contribution plan, IRA, SEP

                purchase may be delayed until the funds have cleared,  which may
                take up to 15 days.  This delay can be  avoided by wiring  funds

                   the  name  or  names  appear  on  the   certificates   or  an
                   accompanying   stock  power  has  been   attached;   and

                payment  at times  when  the  Exchange  is  closed  (other  than
                customary  weekend or  holiday  closings)  or during  periods of
                emergency or other  periods as permitted by the  Securities  and

HERITAGE        of shares of Heritage  Mutual Funds generally will result in the
MUTUAL FUND.    realization  of a taxable  gain or loss for  Federal  income tax
                purposes. See "Taxes."   

                   For  purposes of  calculating  the  commencement  of the CDSL
                holding period for shares exchanged from the Fund to the Class B
                shares  or Class C shares  of any other  Heritage  Mutual  Fund,
                except the Money Market  Fund,  the  original  purchase  date of
                those shares  exchanged  will be used.  Any time period that the
                exchanged  shares were held in the Money Market Fund will not be
                included in this calculation. As a result, if you redeem Class B
                shares or Class C shares of the Money  Market  Fund  before  the
                expiration  of the CDSL holding  period,  you will be subject to
                the applicable CDSL.

                   If you  exchange  Class A  shares,  Class B shares or Class C
                shares for  corresponding  shares of the Money Market Fund,  you
                may,  at any  time  thereafter,  exchange  such  shares  for the
                corresponding class of shares of any other Heritage Mutual Fund.
                If you  exchange  shares of the Money  Market  Fund  acquired by
                purchase  (rather than exchange) for shares of another  Heritage
                Mutual Fund, you will be subject to the sales load, if any, that
                would be applicable to a purchase of that Heritage Mutual Fund.

                   Class A  shares  of the  Fund may be  exchanged  for  Class A
                shares of the Heritage Cash Trust-Municipal Money Fund, which is
                the only class of shares  offered by that fund.  If you exchange
                shares of the Heritage  Cash  Trust-Municipal  Money Market Fund
                acquired  by  purchase  (rather  than  exchange)  for  shares of
                another  Heritage  Mutual Fund,  you also will be subject to the
                sales load,  if any,  that would be  applicable to a purchase of
                that Heritage Mutual Fund. Class B shares and Class C shares are
                not eligible for exchange into the Heritage Cash Trust-Municipal
                Money Market Fund.

                   Shares acquired  pursuant to a telephone request for exchange
                will be held under the same account  registration  as the shares
                redeemed   through  such  an  exchange.   For  a  discussion  of
                limitation of liability of certain entities,  see "How to Redeem
                Shares-Telephone Request."

                   Telephone exchanges can be effected by calling the Manager at
                (800)  421-4184 or by calling  your  Financial  Advisor.  In the
                event that you or your Financial Advisor are unable to reach the
                Manager by  telephone,  an exchange can be effected by sending a
                telegram  to the  Manager.  Due to the  volume of calls or other
                unusual  circumstances,  telephone exchanges may be difficult to
                implement during certain time periods.

                   Each  Heritage  Mutual Fund  reserves the right to reject any
                order to acquire its shares  through  exchange or  otherwise  to
                restrict or  terminate  the exchange  privilege at any time.  In
                addition,  each Heritage Mutual Fund may terminate this exchange
                privilege upon 60 days' notice. For further  information on this
                exchange  privilege  and for a copy of any Heritage  Mutual Fund

                TRANSFER AGENT
                =============================================================

HERITAGE ASSET     Heritage  Asset  Management,  Inc.  is the Fund's  investment
MANAGEMENT,     adviser, fund accountant,  administrator and transfer agent. The
INC. SERVES AS  Manager is responsible for reviewing and establishing investment
INVESTMENT      policies   for  the   Fund  as   well   as   administering   its
ADVISER TO THE  non-investment affairs. The Manager is a wholly owned subsidiary
FUND.           of Raymond  James  Financial,  Inc.,  which,  together  with its
                subsidiaries,  provides a wide range of  financial  services  to
                retail  and   institutional   clients.   The  Manager   manages,
                supervises and conducts the business and administrative  affairs
                of the Fund and the other Heritage  Mutual Funds with net assets
                totaling approximately $3.8 billion as of April 30, 1998. 

                   The Manager's annual investment  advisory and  administration
                fee for the Fund is 1% of the Fund's average daily net assets on
                the first $50 million and 0.75% on average daily net assets over
                $50 million.  This fee is computed  daily and paid monthly.  The
                Manager  voluntarily  waives  fees  or  reimburses  expenses  as
                explained  under "Total Fund Expenses" and reserves the right to
                discontinue any voluntary  waiver of its fees or  reimbursements
                to  the  Fund  in the  future.  The  Manager  may  recover  fees
                previously  waived.  In addition,  the Manager provides the Fund
                with fund  accounting  and transfer agent services for which the
                Manager receives an additional fee directly from the Fund.

                   The Manager may recommend subadvisers to the Board based upon
                its continuing  quantitative  and qualitative  evaluation of the
                subadvisers'  skills in  managing  Fund  assets  using  specific
                styles and  strategies.  Subject to receiving  approval from the
                SEC,  the Manager may be permitted to enter into new or modified
                subadvisory  agreements with existing or new subadvisers without
                approval  of Fund  shareholders,  but subject to approval of the
                Board. Upon SEC approval of such authority,  the SEC would issue
                an exemptive order that would eliminate the need for shareholder
                approval,  subject to compliance with certain conditions.  These
                conditions generally include the requirement that within 90 days
                of hiring a new  subadviser or  implementing  a material  change
                with  respect to a  subadvisory  contract,  the Fund must send a
                notice to shareholders  containing  information about the change
                that would be included in a proxy statement.

                   Shareholders receive Federal income tax information regarding
                dividends  and other  distributions  after the end of each year.
                The information regarding capital gain distributions  designates
                the portions of those  distributions that are subject to (1) the
                20% maximum  rate of tax (10% for  investors in the 15% marginal
                tax bracket)  enacted by the  Taxpayer  Relief Act of 1997 ("Tax
                Act"),  which applies to  non-corporate  taxpayers'  net capital
                gain on securities  and other capital  assets held for more than
                18 months, and (2) the 28% maximum tax rate,  applicable to such
                gain on capital  assets held for more than one year and up to 18
                months (which, prior to enactment of the Tax Act, applied to all
                such gain on capital assets held for more than one year).

                   The  Fund  is  required  to  withhold  31% of all  dividends,
                capital gain  distributions  and redemption  proceeds payable to
                individuals and certain other non-corporate  shareholders who do
                not  provide  the Fund  with a correct  taxpayer  identification
                number. Withholding at that rate also is required from dividends
                and capital gain distributions  payable to such shareholders who
                otherwise  are subject to backup  withholding.  When you sell or
                exchange  shares of the  Fund,  it  generally  is  considered  a
                taxable event to you.

                   The  foregoing  is only a  summary  of some of the  important
                Federal income tax considerations  generally  affecting the Fund
                and its  shareholders.  See the  SAI for a  further  discussion.
                There may be other  Federal,  state or local tax  considerations
                applicable to a particular investor.  You are therefore urged to
                consult your tax adviser.

INVESTMENT INFORMATION
- ----------------------

      Investment Objective
      --------------------

      The Fund's investment objective is stated in the Prospectus.

      Investment Policies
      -------------------

      The following  information  is in addition to and  supplements  the Fund's
investment policies set forth in the Prospectus.

      AMERICAN  DEPOSITORY  RECEIPTS  ("ADRS"),   EUROPEAN  DEPOSITORY  RECEIPTS
("EDRS"),  GLOBAL  DEPOSITORY  RECEIPTS  ("GDRS") AND  INTERNATIONAL  DEPOSITORY
RECEIPTS ("IDRS").  The Fund may invest in sponsored and unsponsored ADRs. ADRs,
EDRs, GDRs and IDRs are receipts that represent  interests in or are convertible
into,  securities  of  foreign  issuers.  These  receipts  are  not  necessarily
denominated  in the same currency as the underlying  securities  into which they
may be converted.

      ADRs may be purchased through "sponsored" or "unsponsored"  facilities.  A
sponsored  facility  is  established  jointly  by the  issuer of the  underlying
security and a depository,  whereas a depository  may  establish an  unsponsored
facility without participation by the issuer of the depository security. Holders
of  unsponsored  depository  receipts  generally  bear  all  the  costs  of such
facilities and the depository of an unsponsored  facility frequently is under no
obligation to distribute shareholder  communications received from the issuer of
the deposited  security or to pass through  voting rights to the holders of such
receipts of the deposited  securities.  Generally,  ADRs in registered  form are
designed  for use in the U.S.  securities  market  and ADRs in  bearer  form are
designed for use outside the United States.

      The Fund also may invest in sponsored or unsponsored  EDRs,  GDRs, IDRs or
other  similar  securities   representing   interests  in  or  convertible  into
securities  of  foreign  issuers  ("Depository  Receipts").  EDRs  and  IDRs are
receipts  typically  issued  by a  European  bank or  trust  company  evidencing
ownership of the underlying  foreign  securities.  GDRs are issued  globally for
trading  in  non-U.S.  securities  markets  and  evidence  a  similar  ownership
arrangement.  Depository Receipts may not necessarily be denominated in the same
currency as the underlying securities into which they may be converted.  As with
ADRs, the issuers of the securities underlying  unsponsored  Depository Receipts
are not  obligated to disclose  material  information  in the United States and,
therefore,  there may be less information  available  regarding such issuers and
there may not be a correlation  between such information and the market value of
the  Depository  Receipts.  Depository  Receipts also involve the risks of other
investments in foreign  securities,  as discussed below. For purposes of certain
investment  limitations,  the Fund considers  EDRs,  GDRs and IDRs to be foreign
securities.

<PAGE>



      BANKERS'  ACCEPTANCES.  The Fund may  invest in  banker's  acceptances.  A
Banker's acceptance is a short-term credit instrument used to finance commercial
transactions.  Generally,  an  acceptance  is a time draft drawn on a bank by an
exporter or an importer to obtain a stated  amount of funds to pay for  specific
merchandise.   The  draft  is  then  "accepted"  by  a  bank  that,  in  effect,
unconditionally  guarantees  to pay the  face  value  of the  instrument  on its
maturity  date.  The  acceptance  may then be held by the  accepting  bank as an
asset,  or it may be sold in the secondary  market at the going rate of interest
for a specified maturity.  Although maturities for acceptances can be as long as
270 days, most acceptances have maturities of six months or less.

      CERTIFICATES  OF  DEPOSIT.  The Fund may  invest in bank  certificates  of
deposit  ("CDs")  issued by  domestic  institutions  with assets in excess of $1
billion.  The Federal  Deposit  Insurance  Corporation  is an agency of the U.S.
Government  that  insures  the  deposits  of certain  banks and savings and loan
associations  up to $100,000 per deposit.  The interest on such deposits may not
be insured if this limit is exceeded.  Current federal  regulations  also permit
such  institutions  to issue  insured  negotiable  CDs in amounts of $100,000 or
more, without regard to the interest rate ceilings on other deposits.  To remain
fully  insured,  these  investments  currently  must be limited to $100,000  per
insured bank or savings and loan association.

      COMMERCIAL  PAPER. The Fund may invest in commercial paper that is limited
to  obligations  rated  Prime-1 or Prime-2 by Moody's  Investors  Service,  Inc.
("Moody's")  or A-1 or  A-2 by  Standard  &  Poor's  ("S&P").  Commercial  paper
includes  notes,  drafts or  similar  instruments  payable on demand or having a
maturity at the time of issuance not exceeding nine months, exclusive of days of
grace or any renewal  thereof.  See the Appendix for a description of commercial
paper ratings.

      CONVERTIBLE  SECURITIES.  The Fund may invest in  convertible  securities.
While no securities investment is without some risk,  investments in convertible
securities  generally entail less risk than the issuer's common stock,  although
the  extent to which  such risk is reduced  depends  in large  measure  upon the
degree to which the convertible security sells above its value as a fixed income
security.  Convertible securities in which the Fund may invest include corporate
bonds,  notes and  preferred  stock that can be  converted  into  common  stock.
Convertible  securities  combine the fixed-income  characteristics  of bonds and
preferred  stock with the potential for capital  appreciation.  As with all debt
securities,  the  market  value of  convertible  securities  tends to decline as
interest rates increase and, conversely,  to increase as interest rates decline.
While convertible  securities  generally offer lower interest or dividend yields
than  nonconvertible  debt  securities  of similar  quality,  they do enable the
investor to benefit from increases in the market price of the underlying  common
stock.
      
      FOREIGN  SECURITIES.  The Fund may  invest in  foreign  securities.  It is
anticipated  that,  in  most  cases,  the  best  available  market  for  foreign
securities will be on exchanges or in  over-the-counter  markets located outside
the  United  States.   Foreign  stock  markets,  while  growing  in  volume  and
sophistication,  generally  are not as developed as those in the United  States,
and securities of some foreign issuers (particularly those located in developing
countries)  may be less liquid and more volatile  than  securities of comparable
U.S. companies. In addition,  foreign brokerage commissions generally are higher
than commissions on securities traded in the United States. In general, there is
less overall  governmental  supervision and regulation of securities  exchanges,
brokers and listed  companies than in the United States.  Investments in foreign
securities  also involve the risk of possible  adverse  changes in investment or
exchange control regulations, expropriation or confiscatory taxation, limitation
on or delays in the removal of funds or other  assets of the Fund,  political or
financial  instability  or diplomatic and other  developments  that could affect
such investments.  Further, the economies of some countries may differ favorably
or unfavorably from the economy of the United States.


                                      -2-
<PAGE>


      It is the Fund's policy not to invest in foreign securities when there are
currency or trading restrictions in force or when, in the judgment of the Fund's
subadviser,  Eagle  Asset  Management,  Inc.  ("Eagle"  or  "Subadviser"),  such
restrictions are likely to be imposed.  However,  certain  currencies may become
blocked  (I.E.,  not freely  available  for  transfer  from a foreign  country),
resulting in the possible  inability  of the Fund to convert  proceeds  realized
upon sale of portfolio  securities of the affected  foreign  companies into U.S.
currency.

      Because  investments in foreign companies usually will involve  currencies
of foreign  countries  and because the Fund may  temporarily  hold funds in bank
deposits in foreign currencies during the completion of investment programs, the
value  of any of Fund  assets  as  measured  in  U.S.  dollars  may be  affected
favorably  or  unfavorably  by changes in foreign  currency  exchange  rates and
exchange  control  regulations,  and the Fund may incur costs in connection with
conversions  between  various  currencies.  The Fund will  conduct  its  foreign
currency  exchange  transactions  on a spot (I.E.,  cash) basis at the spot rate
prevailing in the foreign  currency  exchange market.  In addition,  in order to
protect against  uncertainty in the level of future exchange rates, as described
below in the discussion of futures, forwards, and hedging transactions, the Fund
may enter into contracts to purchase or sell foreign currencies at a future date
(I.E., a "forward currency contract" or "forward contract").

      ILLIQUID  SECURITIES.  The Fund will not purchase or otherwise acquire any
illiquid security,  including repurchase  agreements maturing in more than seven
days, if, as a result,  more than 15% of its net assets (taken at current value)
would be invested in securities  that are illiquid by virtue of the absence of a
readily available market or legal or contractual restrictions on resale.

      INDEX  SECURITIES.  The Fund may invest in Standard and Poor's  MidCap 400
Depositary  Receipts  ("Mid Cap  SPDR's)  and  other  index  securities  ("Index
Securities").  Index  Securities  represent  interests  in a fixed  portfolio of
common stocks  designed to track the price and dividend  yield  performance of a
broad-based  securities index, such as the Standard & Poor's 500 Composite Stock
Price Index ("S&P 500 Index") or the Standard & Poor's MidCap 400 Index, but are
traded on an exchange like shares of common stock. The value of Index Securities
fluctuates  in relation to changes in the value of the  underlying  portfolio of
securities.  However, the market price of Index Securities may not be equivalent
to the pro rata value of the index it tracks.  Index  Securities  are subject to
the risks of an investment in a broadly based portfolio of common stocks.

      PREFERRED STOCK. The Fund may invest in preferred stock. A preferred stock
is a blend of the  characteristics  of a bond and common stock. It can offer the
higher yield of a bond and has priority  over common stock in equity  ownership,
but does not have the seniority of a bond and its  participation in the issuer's
growth may be limited.  Preferred  stock has preference over common stock in the
receipt of  dividends  and in any  residual  assets  after  payment to creditors
should the issuer be  dissolved.  Although the dividend is set at a fixed annual
rate, in some circumstances it can be changed or omitted by the issuer.

      REPURCHASE AGREEMENTS.  The Fund may invest in repurchase agreements.  The
period of these repurchase  agreements  usually will be short, from overnight to
one week,  and at no time will the Fund invest in repurchase  agreements of more
than one  year.  The  securities  that are  subject  to  repurchase  agreements,
however,  may have maturity  dates in excess of one year from the effective date
of the  repurchase  agreement.  The  Fund  always  will  receive  as  collateral
securities  whose market value,  including  accrued  interest,  will be at least
equal to 100% of the dollar amount invested by the Fund in each  agreement,  and
the Fund will make payment for such  securities  only upon physical  delivery or
evidence of book entry transfer to the account of the Fund's custodian bank.


                                      -3-
<PAGE>


      U.S.  GOVERNMENT  SECURITIES.  The  Fund  may  invest  in U.S.  Government
securities,  including a variety of securities  that are issued or guaranteed by
the U.S. Government, its agencies or instrumentalities and repurchase agreements
secured thereby.  These securities  include  securities issued and guaranteed by
the full  faith  and  credit of the U.S.  Government,  such as  Treasury  bills,
Treasury notes,  and Treasury bonds;  obligations  supported by the right of the
issuer to borrow from the U.S. Treasury,  such as those of the Federal Home Loan
Banks; and obligations supported only by the credit of the issuer, such as those
of the Federal Intermediate Credit Banks.

      WARRANTS. The Fund may purchase rights and warrants, which are instruments
that  permit  the Fund to  acquire,  by  subscription,  the  capital  stock of a
corporation at a set price,  regardless of the market price for such stock.  The
Fund  currently  does not  intend  to invest  more than 5% of its net  assets in
warrants.  Warrants may be either perpetual or of limited  duration.  There is a
greater  risk  that  warrants  might  drop in value at a  faster  rate  than the
underlying stock.

      Industry Classifications
      ------------------------

      For purposes of determining industry classifications, the Fund relies upon
classifications  established  by  Heritage  that are based upon  classifications
contained  in  the  Directory  of  Companies  Filing  Annual  Reports  with  the
Securities  and  Exchange  Commission  ("SEC")  and in  the  Standard  &  Poor's
Corporation Industry Classifications.

INVESTMENT LIMITATIONS
- ----------------------

      Fundamental Investment Policies
      -------------------------------

      In addition to the limits disclosed in "Investment Policies" above and the
investment  limitations described in the Prospectus,  the Fund is subject to the
following  investment  limitations that are fundamental  policies and may not be
changed without the vote of a majority of the outstanding  voting  securities of
the Fund.  Under the 1940 Act, a "vote of a majority of the  outstanding  voting
securities"  of the Fund  means the  affirmative  vote of the lesser of (1) more
than 50% of the outstanding  shares of the Fund or (2) 67% or more of the shares
present at a shareholders meeting if more than 50% of the outstanding shares are
represented at the meeting in person or by proxy.

      DIVERSIFICATION. With respect to 75% of its total assets, the Fund may not
invest more than 5% of its assets  (valued at market value) in securities of any
one issuer other than the U.S. Government or its agencies and instrumentalities,
or purchase more than 10% of the voting  securities of the voting  securities of
any one issuer.

      INDUSTRY  CONCENTRATION.  The Fund may not  purchase  securities  if, as a
result of such purchase, more than 25% of the value of its total assets would be
invested in any one industry;  however,  this restriction does not apply to U.S.
Government securities.

      BORROWING  MONEY.  The Fund may not  borrow  money  except as a  temporary
measure for extraordinary or emergency purposes.  Except that the Fund may enter
into reverse  repurchase  agreements  in an amount up to 33 1/3% of the value of
its  total  assets  in order to meet  redemption  requests  without  immediately
selling  portfolio  securities.  This  latter  practice  is not  for  investment
leverage but solely to  facilitate  management  of the  investment  portfolio by
enabling the Fund to meet redemption  requests when the liquidation of portfolio
instruments would be inconvenient or disadvantageous.  However, the Fund may not
purchase additional portfolio investments once borrowed funds exceed 5% of total
assets.  Interest paid on borrowed  funds will not be available for  investment.


                                      -4-
<PAGE>



The Fund will  liquidate  any such  borrowings  as soon as possible  and may not
purchase any portfolio  instruments while any borrowings are outstanding (except
as described above).

      ISSUING  SENIOR  SECURITIES.  The Fund may not  issue  senior  securities,
except as  permitted  by the  investment  objective,  policies,  and  investment
limitations  of the  Fund,  except  that  the Fund may  engage  in  transactions
involving forward currency contracts, or other financial instruments.

      UNDERWRITING. Subject to the following exceptions, the Fund may underwrite
the securities of other issuers:  (1) the Fund may underwrite  securities to the
extent that, in connection with the disposition of portfolio securities,  it may
be deemed to be an underwriter  under federal  securities laws, and (2) the Fund
may invest not more than 15% of its net assets (taken at cost immediately  after
making such  investment) in securities that are not readily  marketable  without
registration under the 1933 Act.

      INVESTING  IN  COMMODITIES,  MINERALS OR REAL ESTATE.  With the  following
exceptions, the Fund may not invest in commodities,  commodity contracts or real
estate (including real estate limited  partnerships):  the Fund may purchase (1)
securities  issued by companies  that invest in or sponsor such  interests,  (2)
purchase and sell forward currency contracts and other financial instruments.

      LOANS.  The Fund may not make  loans,  except that it may make loans under
the following circumstances: (1) to the extent that the purchase of a portion of
an  issue  of  publicly   distributed  notes,   bonds,  or  other  evidences  of
indebtedness  or deposits  with banks and other  financial  institutions  may be
considered loans and (2) where the Fund may enter into repurchase  agreements as
permitted under its investment policies.

      Non-fundamental Investment Policies
      -----------------------------------

      The Fund has adopted the following additional restrictions which, together
with certain limits described in the Prospectus,  may be changed by the Board of
Trustees  without  shareholder  approval  in  compliance  with  applicable  law,
regulation or regulatory policy.

      INVESTING IN ILLIQUID SECURITIES. The Fund may not invest more than 15% of
its net assets in repurchase  agreements  maturing in more than seven days or in
other illiquid  securities,  including securities that are illiquid by virtue of
the absence of a readily  available market or legal or contractual  restrictions
as to resale.

      SELLING SHORT AND BUYING ON MARGIN.  The Fund may not sell any  securities
short or  purchase  any  securities  on margin  but may obtain  such  short-term
credits as may be necessary for clearance of purchases and sales of  securities;
and, in addition,  the Fund may make margin  deposits in connection with its use
of forward currency contracts and other financial instruments.

      INVESTING IN INVESTMENT  COMPANIES.  The Fund may not invest in securities
issued by other investment companies except as permitted by the 1940 Act, except
in  connection  with  the  merger,  consolidation  or  acquisition  of  all  the
securities or assets of such an issuer.

NET ASSET VALUE
- ---------------

      The net asset value per share of Class A shares,  Class B shares and Class
C shares is determined  separately  daily as of the close of regular  trading on
the New York Stock Exchange (the  "Exchange")  each day the Exchange is open for
business.


                                      -5-
<PAGE>



      A security listed or traded on the Exchange,  or other domestic or foreign
stock exchanges,  is valued at its last sales price on the principal exchange on
which it is  traded  prior to the time when  assets  are  valued.  If no sale is
reported  at that time or the  security  is traded  in the OTC  market  the most
recent  quoted bid price is used.  Securities  and other assets for which market
quotations are not readily available,  or for which market quotes are not deemed
to be  reliable,  are  valued at fair value as  determined  in good faith by the
Board of Trustees.  Securities and other assets in foreign  currency and foreign
currency  contracts will be valued daily in U.S. dollars at the foreign currency
exchange  rates  prevailing at the time the Fund  calculates the daily net asset
value of each class. Short-term investments having a maturity of 60 days or less
are valued at cost with accrued interest or discount earned included in interest
receivable.

      All  securities  and other assets  quoted in foreign  currency and forward
currency  contracts are valued daily in U.S. dollars on the basis of the foreign
currency  exchange rate  prevailing at the time such  valuation is determined by
the Fund's custodian  ("Custodian").  Foreign currency  exchange rates generally
are  determined  prior  to the  close  of  the  Exchange.  Occasionally,  events
affecting the value of foreign  securities and such exchange rates occur between
the time at which  they are  determined  and the  close of the  Exchange,  which
events will not be reflected in a computation of the Fund's net asset value.  If
events  materially  affecting the value of such securities or assets or currency
exchange rates occurred during such time period,  the securities or assets would
be valued at their  fair value as  determined  in good  faith  under  procedures
established by and under the general supervision and responsibility of the Board
of Trustees. The foreign currency exchange transactions of the Fund conducted on
a spot basis are  valued at the spot rate for  purchasing  or  selling  currency
prevailing on the foreign exchange market.

      The Fund is open for  business on days on which the Exchange is open (each
a "Business Day").  Trading in securities on European and Far Eastern securities
exchanges and OTC markets  normally is completed well before the Fund's close of
business on each Business Day. In addition,  European or Far Eastern  securities
trading may not take place on all  Business  Days.  Furthermore,  trading  takes
place in various  foreign capital markets on days that are not Business Days and
on which the Fund's net asset value is not calculated.  Calculation of net asset
value of Class A shares,  Class B shares and Class C shares  does not take place
contemporaneously  with the  determination  of the prices of the majority of the
portfolio  securities  used in such  calculation.  The Fund calculates net asset
value per share and, therefore, effect sales and redemptions, as of the close of
regular  trading  on the  Exchange  each  Business  Day.  If  events  materially
affecting  the value of such  securities  or other assets occur between the time
when their  prices are  determined  (including  their  value in U.S.  dollars by
reference to foreign  currency  exchange rates) and the time when the Fund's net
asset value is  calculated,  such  securities and other assets will be valued at
fair value by methods as  determined  in good faith by or under the direction of
the Board of Trustees.

      The Board of  Trustees  may suspend  the right of  redemption  or postpone
payment  for more than  seven  days at times (1) during  which the  Exchange  is
closed other than for the  customary  weekend and holiday  closings,  (2) during
which trading on the Exchange is restricted as determined by the SEC, (3) during
which an  emergency  exists  as a result  of which  disposal  by the Fund of its
securities is not reasonably  practicable or it is not reasonably  practical for
the Fund fairly to determine the value of its net assets,  or (4) for such other
periods as the SEC may by order  permit  for the  protection  of the  holders of
Class A shares, Class B shares and Class C shares.

PERFORMANCE INFORMATION
- -----------------------

      The Fund's  performance  data quoted in advertising and other  promotional
materials  represents  past  performance  and is not intended to indicate future
performance.  The investment  return and principal  value of an investment  will
fluctuate so that an investor's shares, when redeemed, may be worth more or less


                                      -6-
<PAGE>


than their original cost. Average annual total return quotes for each class used
in the Fund's advertising and promotional  materials are calculated according to
the following formula:

                              P(1+T)[SUPERSCRIPT]n = ERV
          where:  P     =     a hypothetical initial payment of $1,000
                  T     =     average annual total return
                  n     =     number of years
                  ERV   =     ending   redeemable   value  of  a  hypothetical
                              $1,000  payment  made  at the  beginning  of the
                              period at the end of that period

      In calculating the ending redeemable value for Class A shares,  the Fund's
current  maximum sales load of 4.75% is deducted from the initial $1,000 payment
and,  for Class B shares and Class C shares,  the  applicable  CDSL imposed on a
redemption  of Class B shares or Class C shares held for the period is deducted.
All  dividends  and other  distributions  by the Fund are  assumed  to have been
reinvested at net asset value on the reinvestment dates during the period. Based
on this formula,  the total return,  or "T" in the formula above, is computed by
finding the average annual compounded rates of return over the period that would
equate the initial amount invested to the ending redeemable value.

      In  connection  with   communicating   its  total  return  to  current  or
prospective  shareholders,  the  Fund  also may  compare  these  figures  to the
performance  of other mutual funds tracked by mutual fund rating  services or to
other unmanaged indexes that may assume  reinvestment of dividends but generally
do not reflect  deductions for administrative and management costs. In addition,
the Fund may from time to time include in advertising and promotional  materials
total return figures that are not calculated  according to the formula set forth
above for each class of shares.  For example,  in comparing the Fund's aggregate
total  return with data  published  by Lipper  Analytical  Services,  Inc.,  CDA
Investment  Technologies,  Inc.,  or with such  market  indices as the Dow Jones
Industrial  Average,  and the S&P 500 Index,  the Fund calculates its cumulative
total  return for each class for the  specified  periods of time by  assuming an
investment of $10,000 in that class of shares and assuming the  reinvestment  of
each dividend or other distribution at net asset value on the reinvestment date.
Percentage  increases  are  determined by  subtracting  the initial value of the
investment  from the ending value and by dividing the remainder by the beginning
value.  The Fund does not,  for these  purposes,  deduct from the initial  value
invested any amount representing front-end sales loads charged on Class A shares
or CDSLs charged on Class B shares and Class C shares.  By not  annualizing  the
performance  and  excluding  the effect of the  front-end  sales load on Class A
shares  and the CDSL on Class B shares  and  Class C shares,  the  total  return
calculated  in this manner  simply will  reflect the increase in net asset value
per share over a period of time, adjusted for dividends and other distributions.
Calculating  total  return  without  taking into  account the sales load or CDSL
results in a higher  rate of return  than  calculating  total  return net of the
front-end sales load.


INVESTING IN THE FUND
- ---------------------

      Class A shares,  Class B shares  and Class C shares are sold at their next
determined  net asset value on Business  Days.  The  procedures  for  purchasing
shares of the Fund are explained in the Prospectus under "Purchase Procedures."

      Systematic Investment Options
      -----------------------------

      The options below allow you to invest  continually  in the Fund at regular
intervals.


                                      -7-
<PAGE>



      1.    Systematic  Investing  -- You may  authorize  Heritage  to process a
monthly draft from your personal  checking account for investment into the Fund.
The draft is returned by your bank the same way a canceled check is returned.

      2.    Payroll Direct Deposit -- If your employer  participates in a direct
deposit  program  (also known as ACH  Deposits) you may have all or a portion of
your payroll  directed to the Fund.  This will  generate a purchase  transaction
each time you are paid by your  employer.  Your  employer will report to you the
amount sent from each paycheck.

      3.    Government  Direct  Deposit -- If you receive a qualifying  periodic
payment from the U.S.  Government  or other agency that  participates  in Direct
Deposit, you may have all or a part of each check directed to purchase shares of
the Fund. The U.S. Government or agency will report to you all payments made.

      4.    Automatic  Exchange -- If you own shares of another  Heritage mutual
fund advised or administered by Heritage ("Heritage Mutual Fund"), you may elect
to have a  preset  amount  redeemed  from  that  fund  and  exchanged  into  the
corresponding class of shares of the Fund. You will receive a statement from the
other Heritage Mutual Fund confirming the redemption.

      You may change or terminate any of the above options at any time.

      Retirement Plans
      ----------------

      HERITAGE IRA.  Individuals who earn  compensation and who have not reached
age 70 1/2  before  the close of the year  generally  may  establish  a Heritage
Individual   Retirement   Account  ("IRA").   An  individual  may  make  limited
contributions  to a Heritage  IRA  through  the  purchase  of shares of the Fund
and/or  other  Heritage  Mutual  Funds.  The Internal  Revenue Code of 1986,  as
amended (the "Code"), limits the deductibility of IRA contributions to taxpayers
who are not active participants (and whose spouses are not active  participants)
in  employer-provided  retirement  plans or who have adjusted gross income below
certain  levels.  Nevertheless,  the  Code  permits  other  individuals  to make
nondeductible  IRA  contributions  up to  $2,000  per year (or  $4,000,  if such
contributions  also are made  for a  nonworking  spouse  and a joint  return  is
filed). In addition,  individuals  whose earnings  (together with their spouse's
earnings) do not exceed a certain level may establish an "education  IRA" and/or
a "Roth IRA"; although  contributions to these new types of IRAs (established by
the Taxpayer Relief Act of 1997 ("Tax Act")) are nondeductible, withdrawals from
them will not be taxable under certain circumstances. A Heritage IRA also may be
used for certain  "rollovers"  from  qualified  benefit  plans and from  Section
403(b) annuity plans. For more detailed  information on the Heritage IRA, please
contact Heritage.

      Fund shares also may be used as the investment  medium for qualified plans
(defined  benefit or defined  contribution  plans  established by  corporations,
partnerships or sole  proprietorships).  Contributions to qualified plans may be
made   (within   certain   limits)  on  behalf  of  the   employees,   including
owner-employees, of the sponsoring entity.

      OTHER RETIREMENT PLANS.  Multiple participant payroll deduction retirement
plans also may purchase Class A shares of any Heritage  Mutual Fund at a reduced
sales load on a monthly basis during the 13-month period following such a plan's
initial  purchase.  The sales load applicable to an initial  purchase of Class A
shares will be that  normally  applicable  under the schedule of sales loads set
forth in the  Prospectus  to an  investment  13 times  larger  than the  initial
purchase. The sales load applicable to each succeeding monthly purchase of Class
A shares will be that normally applicable,  under the schedule, to an investment
equal to the sum of (1) the total purchase  previously  made during the 13-month


                                      -8-
<PAGE>



period and (2) the current month's  purchase  multiplied by the number of months
(including  the current  month)  remaining in the 13-month  period.  Sales loads
previously  paid during such  period will not be adjusted  retroactively  on the
basis of later purchases.  Multiple  participant  payroll  deduction  retirement
plans may purchase Class C shares at any time.

      Class A Combined Purchase Privilege (Right Of Accumulation)
      -----------------------------------------------------------

      Certain  investors  may  qualify  for the  Class A sales  load  reductions
indicated in the sales load schedule in the Prospectus by combining purchases of
Class A shares into a single  "purchase,"  if the resulting  purchase  totals at
least $25,000. The term "purchase" refers to a single purchase by an individual,
or to concurrent  purchases  that, in the  aggregate,  are at least equal to the
prescribed  amounts,  by an individual,  his spouse and their children under the
age of 21 years purchasing Class A shares for his or their own account; a single
purchase by a trustee or other fiduciary  purchasing Class A shares for a single
trust,  estate or single fiduciary account although more than one beneficiary is
involved;  or a  single  purchase  for the  employee  benefit  plans of a single
employer.  The term  "purchase"  also includes  purchases by a "company," as the
term is  defined in the 1940 Act,  but does not  include  purchases  by any such
company  that has not been in  existence  for at least six months or that has no
purpose other than the purchase of Class A shares or shares of other  registered
investment companies at a discount; provided, however, that it shall not include
purchases by any group of individuals  whose sole  organizational  nexus is that
the participants therein are credit card holders of a company, policy holders of
an insurance company, customers of either a bank or broker-dealer, or clients of
an investment adviser. A "purchase" also may include Class A shares purchased at
the same time through a single selected dealer of any other Heritage Mutual Fund
that distributes its shares subject to a sales load.

      The  applicable  Class A shares  initial  sales  load will be based on the
total of:

            (i)    the investor's current purchase;

            (ii)   the net asset value (at the close of business on the previous
day) of (a) all  Class A shares  of the Fund  held by the  investor  and (b) all
Class A shares of any  other  Heritage  Mutual  Fund  held by the  investor  and
purchased  at a time when  Class A shares of such  other  fund were  distributed
subject to a sales  load  (including  Heritage  Cash Trust  shares  acquired  by
exchange); and

            (iii)  the net  asset  value  of all  Class A  shares  described  in
paragraph  (ii) owned by another  shareholder  eligible to combine his  purchase
with that of the investor into a single "purchase."

      Class A shares  of  Heritage  Income  Trust-Intermediate  Government  Fund
("Intermediate  Government")  purchased  from  February 1, 1992 through July 31,
1992,  without  payment  of a sales  load  will be  deemed  to  fall  under  the
provisions  of  paragraph  (ii) as if they had been  distributed  without  being
subject to a sales load,  unless those shares were acquired  through an exchange
of other shares that were subject to a sales load.

      To qualify for the Combined  Purchase  Privilege  on a purchase  through a
selected  dealer,  the  investor  or  selected  dealer  must  provide the Fund's
distributor,  Raymond James & Associates, Inc. ("Distributor"),  with sufficient
information to verify that each purchase qualifies for the
privilege or discount.

<PAGE>



      Class A Statement Of Intention
      ------------------------------

      Investors  also may obtain the reduced sales loads shown in the Prospectus
by means of a written  Statement of Intention,  which  expresses the  investor's
intention to invest not less than $25,000  within a period of 13 months in Class
A shares of the Fund or any other Heritage Mutual Fund. Each purchase of Class A
shares under a Statement of Intention will be made at the public  offering price
or prices applicable at the time of such purchase to a single transaction of the
dollar amount indicated in the Statement. In addition, if you own Class A shares
of any other Heritage Mutual Fund subject to a sales load, you may include those
shares in computing the amount necessary to qualify for a sales load reduction.

      The Statement of Intention is not a binding  obligation  upon the investor
to purchase the full amount  indicated.  The minimum initial  investment under a
Statement of Intention is 5% of such amount.  Class A shares  purchased with the
first 5% of such amount will be held in escrow  (while  remaining  registered in
the name of the investor) to secure payment of the higher sales load  applicable
to the shares actually  purchased if the full amount indicated is not purchased,
and such  escrowed  Class A shares  will be  redeemed  involuntarily  to pay the
additional  sales load,  if necessary.  When the full amount  indicated has been
purchased, the escrow will be released. To the extent an investor purchases more
than the dollar amount indicated on the Statement of Intention and qualifies for
a further  reduced  sales load,  the sales load will be adjusted  for the entire
amount purchased at the end of the 13-month period. The difference in sales load
will be used to purchase  additional  Class A shares of the Fund  subject to the
rate of sales load  applicable to the actual amount of the aggregate  purchases.
An investor may amend  his/her  Statement of Intention to increase the indicated
dollar amount and begin a new 13-month  period.  In that case,  all  investments
subsequent  to the  amendment  will be made at the sales  load in effect for the
higher amount. The escrow procedures discussed above will apply.

REDEEMING SHARES
- ----------------

      The  methods  of  redemption   are  described  in  the  section  of  the
Prospectus entitled "How to Redeem Shares."

      Systematic Withdrawal Plan
      --------------------------

      Shareholders  may  elect  to make  systematic  withdrawals  from  the Fund
account of a minimum of $50 on a periodic  basis.  The amounts  paid each period
are  obtained  by  redeeming  sufficient  shares  from an account to provide the
withdrawal  amount  specified.  The Systematic  Withdrawal Plan currently is not
available for shares held in an individual  retirement  account,  Section 403(b)
annuity plan, defined  contribution plan,  simplified  employee pension plan, or
other  retirement  plans,  unless  the  shareholder  establishes  to  Heritage's
satisfaction  that  withdrawals  from  such  an  account  may  be  made  without
imposition of a penalty.  Shareholders  may change the amount to be paid without
charge  not more  than  once a year by  written  notice  to the  Distributor  or
Heritage.

      Redemptions  will be made at net asset value determined as of the close of
regular  trading  on  the  Exchange  on a  day  of  each  month  chosen  by  the
shareholders  or a  day  of  the  last  month  of  each  period  chosen  by  the
shareholders, whichever is applicable. Systematic withdrawals of Class C shares,
if made in less than one year of the date of purchase, will be charged a CDSL of
1%. If the  Exchange is not open for  business  on that day,  the shares will be
redeemed at net asset value determined as of the close of regular trading on the
Exchange on the preceding  Business Day, minus any  applicable  CDSL for Class B
shares  and Class C  shares.  If a  shareholder  elects  to  participate  in the
Systematic  Withdrawal Plan,  dividends and other distributions on all shares in
the account must be reinvested  automatically  in Fund shares. A shareholder may
terminate the Systematic  Withdrawal  Plan at any time without charge or penalty


                                      -10-
<PAGE>



by giving  written  notice to Heritage  or the  Distributor.  The Fund,  and the
transfer agent and Distributor also reserve the right to modify or terminate the
Systematic Withdrawal Plan at any time.

      Withdrawal  payments  are  treated  as a sale of shares  rather  than as a
dividend  or a capital  gain  distribution.  These  payments  are taxable to the
extent that the total amount of the payments exceeds the tax basis of the shares
sold.  If  the  periodic  withdrawals  exceed  reinvested  dividends  and  other
distributions,  the amount of the  original  investment  may be  correspondingly
reduced.

      Ordinarily, a shareholder should not purchase additional Class A shares of
the Fund if maintaining a Systematic  Withdrawal  Plan of Class A shares because
the  shareholder may incur tax liabilities in connection with such purchases and
withdrawals.   The  Fund  will  not  knowingly   accept   purchase  orders  from
shareholders  for  additional  Class A  shares  if they  maintain  a  Systematic
Withdrawal  Plan unless the  purchase is equal to at least one year's  scheduled
withdrawals.  In addition,  a shareholder who maintains such a Plan may not make
periodic investments under the Fund's Automatic Investment Plan.

      Telephone Transactions
      ----------------------

      Shareholders may redeem shares by placing a telephone request to the Fund.
The Fund, Heritage, the Distributor and their Trustees,  directors, officers and
employees are not liable for any loss arising out of telephone instructions they
reasonably believe are authentic. In acting upon telephone  instructions,  these
parties  use  procedures  that are  reasonably  designed  to  ensure  that  such
instructions  are genuine,  such as (1)  obtaining  some or all of the following
information:  account number,  name(s) and social security number  registered to
the  account,   and  personal   identification;   (2)  recording  all  telephone
transactions;  and (3) sending written  confirmation of each  transaction to the
registered  owner.  If the Fund,  Heritage,  the Distributor and their Trustees,
directors,  officers and employees do not follow reasonable procedures,  some or
all of them may be liable for any such losses.

      Redemptions In Kind
      -------------------

      The Fund is obligated to redeem shares for any shareholder for cash during
any 90-day period up to $250,000 or 1% of that Fund's net asset value, whichever
is less. Any redemption beyond this amount also will be in cash unless the Board
of Trustees  determine  that further cash payments will have a material  adverse
effect on  remaining  shareholders.  In such a case,  the Fund will pay all or a
portion of the remainder of the redemption in portfolio  instruments,  valued in
the same way the Fund determines net asset value. The portfolio instruments will
be selected in a manner that the Board of Trustees  deem fair and  equitable.  A
redemption  in kind is not as liquid as a cash  redemption.  If a redemption  is
made in kind, a shareholder  receiving portfolio  instruments could receive less
than the redemption value thereof and could incur certain transaction costs.

      Receiving Payment
      -----------------

      If  shares  of  the  Fund  are  redeemed  by  a  shareholder  through  the
Distributor  or a  participating  dealer,  the  redemption  is settled  with the
shareholder as an ordinary transaction.  If a request for redemption is received
before the close of regular trading on the Exchange,  shares will be redeemed at
the net asset value per share  determined on that day, minus any applicable CDSL
for Class B shares and Class C shares.  Requests for  redemption  received after
the close of  regular  trading  on the  Exchange  will be  executed  on the next
trading day.  Payment for shares  redeemed  normally will be made by the Fund to
the  Distributor or a  participating  dealer by the third business day after the
day the redemption request was made,  provided that certificates for shares have
been  delivered in proper form for transfer to the Fund,  or if no  certificates


                                      -11-
<PAGE>



have been issued,  a written request signed by the shareholder has been provided
to the Distributor or a participating dealer prior to settlement date.

      Other  supporting  legal  documents may be required from  corporations  or
other organizations, fiduciaries or persons other than the shareholder of record
making the request for redemption.  Questions  concerning the redemption of Fund
shares can be directed to registered  representatives  of the  Distributor  or a
participating dealer, or to Heritage.

EXCHANGE PRIVILEGE
- ------------------

      An exchange is effected  through the redemption of the shares tendered for
exchange and the purchase of shares being acquired at their respective net asset
values as next  determined  following  receipt by the Heritage Mutual Fund whose
shares  are  being  exchanged  of (1)  proper  instructions  and  all  necessary
supporting documents as described in such fund's Prospectus,  or (2) a telephone
request for such exchange in  accordance  with the  procedures  set forth in the
Prospectus and below. Telephone or telegram requests for an exchange received by
the Fund before the close of regular trading on the Exchange will be effected at
the close of regular  trading on that day.  Requests  for an  exchange  received
after the close of regular  trading  will be  effected  on the  Exchange's  next
trading day.

      Class A shares of Intermediate  Government purchased from February 1, 1992
through July 31, 1992, without payment of an initial sales load may be exchanged
into  Class A shares of the Fund  without  payment  of any sales  load.  Class A
shares of  Intermediate  Government  purchased  after July 31,  1992  without an
initial sales load will be subject to a sales load when  exchanged  into Class A
shares of the Fund,  unless  those shares were  acquired  through an exchange of
other Class A shares that were subject to an initial sales load.

CONVERSION OF CLASS B SHARES
- ----------------------------

      Class B shares of the Fund  automatically  will convert to Class A shares,
based on the relative net asset values per share of the two classes, eight years
after the end of the calendar month in which the shareholder's order to purchase
was accepted.  For the purpose of calculating  the holding  period  required for
conversion of Class B shares,  the date of initial  issuance  shall mean (i) the
date on  which  such  Class B shares  were  issued  or (ii)  for  Class B shares
obtained  through an exchange,  or a series of exchanges,  the date on which the
original  Class B shares were  issued.  For  purposes of  conversion  to Class A
shares, Class B shares purchased through the reinvestment of dividends and other
distributions  paid in  respect  of  Class B shares  will be held in a  separate
sub-account.  Each time any Class B shares in the shareholder's  regular account
(other  than those in the  sub-account)  convert  to Class A shares,  a pro rata
portion of the Class B shares in the  sub-account  will also  convert to Class A
shares. The portion will be determined by the ratio that the shareholder's Class
B shares converting to Class A shares bears to the  shareholder's  total Class B
shares not acquired through dividends and other distributions.

      The  availability  of the conversion  feature is subject to the continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions  paid on Class A shares  and  Class B shares  will not  result  in
"preferential  dividends"  under the Code and the  conversion of shares does not
constitute a taxable event.  If the  conversion  feature ceased to be available,
the Class B shares  would not be converted  and would  continue to be subject to
the higher  ongoing  expenses of the Class B shares  beyond eight years from the
date of purchase.  Heritage has no reason to believe that this condition for the
availability of the conversion feature will not be met.

TAXES
- -----

      GENERAL.  The Fund is treated as a separate corporation for Federal income
tax purposes. In order to qualify for the favorable tax treatment as a regulated
investment company ("RIC") under the Code, the Fund must distribute  annually to
its  shareholders  at  least  90%  of  its  investment  company  taxable  income
(generally  consisting of net investment income, net short-term capital gain and
net  gains  from   certain   foreign   currency   transactions)   ("Distribution
Requirement") and must meet several additional requirements.  These requirements
include the following: (1) the Fund must derive at least 90% of its gross income
each taxable year from dividends,  interest, payments with respect to securities
loans and gains  from the sale or other  disposition  of  securities  or foreign
currencies,  or other income  (including gains from forward currency  contracts)
derived  with  respect to its  business  of  investing  in  securities  or those
currencies  ("Income  Requirement");  (2) at the  close of each  quarter  of the
Fund's  taxable  year,  at least 50% of the value of its  total  assets  must be
represented by cash and cash items, U.S.  Government  securities,  securities of
other RICs and other securities, with those other securities limited, in respect
of any one  issuer,  to an amount  that  does not  exceed 5% of the value of the
Fund's  total assets and that does not  represent  more than 10% of the issuer's
outstanding  voting  securities;  and (3) at the  close of each  quarter  of the
Fund's  taxable year,  not more than 25% of the value of its total assets may be
invested in securities (other than U.S. Government  securities or the securities
of other RICs) of any one issuer.

      The Fund will be subject to a  nondeductible  4% excise tax ("Excise Tax")
to the  extent  it  fails  to  distribute  by  the  end  of  any  calendar  year
substantially  all of its ordinary income for that year and its capital gain net
income for the one-year  period ending on October 31 of that year,  plus certain
other amounts.

      A  redemption  of Fund shares will result in a taxable gain or loss to the
redeeming shareholder,  depending on whether the redemption proceeds are more or
less than the  shareholder's  adjusted  basis  for the  redeemed  shares  (which
normally  includes  any sales load paid on Class A shares).  An exchange of Fund
shares for shares of another  Heritage  Mutual Fund  generally will have similar
tax consequences.  However,  special rules apply when a shareholder  disposes of
Class A shares of the Fund through a redemption or exchange within 90 days after
purchase  thereof  and  subsequently  reacquires  Class A shares  of the Fund or
acquires Class A shares of another  Heritage  Mutual Fund without paying a sales
load due to the 90-day reinstatement or exchange privilege.  In these cases, any
gain on the  disposition  of the original  Class A shares will be increased,  or
loss  decreased,  by the amount of the sales load paid when  those  shares  were
acquired,  and that  amount  will  increase  the  adjusted  basis of the  shares
subsequently  acquired.  In  addition,  if Fund  shares are  purchased  (whether
pursuant to the  reinstatement  privilege or otherwise) within 30 days before or
after redeeming other shares of the Fund (regardless of class) at a loss, all or
a portion of that loss will not be deductible and will increase the basis of the
newly purchased shares.

      If shares of the Fund are sold at a loss  after  being held for six months
or less, the loss will be treated as long-term,  instead of short-term,  capital
loss to the extent of any capital gain  distributions  received on those shares.
Investors  also should be aware that if shares are purchased  shortly before the
record date for a dividend or other distribution,  the shareholder will pay full
price for the shares  and  receive  some  portion of the price back as a taxable
distribution.







                                      -13-
<PAGE>



      INCOME FROM FOREIGN  SECURITIES.  Dividends  and interest  received by the
Fund may be subject to income,  withholding  or other  taxes  imposed by foreign
countries and U.S. possessions  ("foreign taxes") that would reduce the yield on
its securities.  Tax conventions between certain countries and the United States
may reduce or eliminate these foreign taxes, however, and many foreign countries
do not impose  taxes on  capital  gains in  respect  of  investments  by foreign
investors.

      The Fund may invest in the stock of "passive foreign investment companies"
("PFICs").  A PFIC is a foreign  corporation - other than a "controlled  foreign
corporation"  (I.E.,  a foreign  corporation  in which,  on any day  during  its
taxable  year,  more  than 50% of the total  voting  power of all  voting  stock
therein or the total value of all stock therein is owned, directly,  indirectly,
or  constructively,  by  "U.S.  shareholders,"  defined  as  U.S.  persons  that
individually own, directly, indirectly, or constructively,  at least 10% of that
voting  power) as to which the Fund is a U.S.  shareholder  -- that, in general,
meets  either of the  following  tests:  (1) at least 75% of its gross income is
passive or (2) an average of at least 50% of its assets produce, or are held for
the production of, passive income. Under certain circumstances, the Fund will be
subject to Federal income tax on a portion of any "excess distribution" received
on the stock of a PFIC or of any gain on disposition of the stock  (collectively
"PFIC income"),  plus interest  thereon,  even if the Fund  distributes the PFIC
income as a taxable dividend to its shareholders. The balance of the PFIC income
will  be  included  in  the  Fund's  investment   company  taxable  income  and,
accordingly,  will not be taxable to it to the extent that income is distributed
to its shareholders.

      If the Fund invests in a PFIC and elects to treat the PFIC as a "qualified
electing  fund"  ("QEF"),  then  in  lieu  of the  foregoing  tax  and  interest
obligation,  the Fund will be  required  to include in income  each year its pro
rata share of the QEF's  annual  ordinary  earnings  and net  capital  gain (the
excess of net long-term capital gain over net short-term  capital loss) -- which
most likely would have to be distributed by the Fund to satisfy the Distribution
Requirement and avoid imposition of the Excise Tax -- even if those earnings and
gain were not  distributed  to the Fund by the QEF. In most instances it will be
very  difficult,  if not  impossible,  to make this election  because of certain
requirements thereof.

      The  Fund  may   elect  to   "mark-to-market"   its  stock  in  any  PFIC.
"Marking-to-market,"  in this context,  means  including in ordinary income each
taxable year the excess, if any, of the fair market value of a PFIC's stock over
the Fund's  adjusted  basis therein as of the end of that year.  Pursuant to the
election, the Fund also would be allowed to deduct (as an ordinary, not capital,
loss) the  excess,  if any,  of its  adjusted  basis in PFIC stock over the fair
market value thereof as of the taxable  year-end,  but only to the extent of any
net  mark-to-market  gains with  respect to that stock  included by the Fund for
prior taxable years. The Fund's adjusted basis in each PFIC's stock with respect
to which it makes this  election  will be  adjusted  to reflect  the  amounts of
income included and deductions taken under the election. Regulations proposed in
1992  would  provide a similar  election  with  respect  to the stock of certain
PFICs.

      Gains or losses (1) from the  disposition of foreign  currencies,  and (2)
that are  attributable  to fluctuations in exchange rates that occur between the
time the Fund  accrues  dividends,  interest  or other  receivables  or  accrues
expenses or other liabilities denominated in a foreign currency and the time the
Fund actually  collects the receivables or pays the liabilities,  generally will
be treated as ordinary income or loss. These gains or losses,  referred to under
the Code as "section  988" gains or losses,  may increase or decrease the amount
of the  Fund's  investment  company  taxable  income  to be  distributed  to its
shareholders.

      Investors  are advised to consult  their own tax  advisers  regarding  the
status of an investment in the Fund under state and local tax laws.

      *     These  Trustees  are  "interested  persons"  as defined in section
2(a)(19) of the 1940 Act.

      The Trustees and  officers of the Trust,  as a group,  own less than 1% of
each class of the Fund's shares  outstanding.  The Trust's  Declaration of Trust
provides that the Trustees will not be liable for errors of judgment or mistakes
of fact or law.  However,  they are not protected against any liability to which
they would  otherwise  be subject by reason of willful  misfeasance,  bad faith,
gross negligence or reckless  disregard of the duties involved in the conduct of
their office.

      The Trust currently pays Trustees who are not "interested  persons" of the
Trust  $3,333  annually  and $1,250 per  meeting of the Board of  Trustees.  The
Trustees also are  reimbursed for any expenses  incurred in attending  meetings.
Because Heritage performs  substantially  all of the services  necessary for the
Fund;s  operation,  the Fund  requires no  employees.  No  officer,  director or
employee of Heritage  receives  any  compensation  from the Fund for acting as a
director or officer.  The following table shows the compensation  earned by each
Trustee for the Trust's prior fiscal year ended.

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

   (1)  For the fiscal year ended October 31, 1997.

   (2)  The Heritage Mutual Funds consist of six separate registered  investment
        companies, including the Trust.

      No Trustee will receive any benefits upon retirement.  Thus, no pension or
retirement benefits have accrued as part of any of any Trust's expenses.

      Investment Adviser and Administrator; Subadviser
      ------------------------------------------------

      The investment  adviser and  administrator  for the Fund is Heritage Asset
Management,  Inc.  Heritage was organized as a Florida  corporation in 1985. All
the capital stock of Heritage is owned by Raymond James Financial, Inc. ("RJF").
RJF is a holding company that, through its subsidiaries, is engaged primarily in
providing customers with a wide variety of financial services in connection with
securities,  limited  partnerships,  options,  investment  banking  and  related
fields.

      Heritage  is  responsible   for  overseeing  the  Fund's   investment  and
noninvestment  affairs,  subject to the  control and  direction  of the Board of
Trustees.  The Trust, on behalf of the Fund, entered into an Investment Advisory
and  Administration  Agreement  with  Heritage  dated  March  29,  1993 and last
supplemented  on August __, 1998.  The  Investment  Advisory and  Administration
Agreement  requires that Heritage review and establish  investment  policies for
the Fund and administer the Fund's noninvestment affairs.

      Under an  Subadvisory  Agreement,  Eagle,  subject  to the  direction  and
control  of the Board of  Trustees,  provide  investment  advice  and  portfolio
management services to the Fund for a fee payable by Heritage.

      Heritage  also is  obligated  to  furnish  the  Fund  with  office  space,
administrative,  and  certain  other  services  as well as  executive  and other
personnel  necessary for the operation of the Fund.  Heritage and its affiliates


                                      -17-
<PAGE>


also pay all the  compensation  of  Trustees of the Trust who are  employees  of
Heritage and its  affiliates.  The Fund pays all its other expenses that are not
assumed by Heritage.  The Fund also is liable for such nonrecurring  expenses as
may arise,  including litigation to which the Fund may be a party. The Fund also
may have an  obligation  to indemnify  its Trustees and officers with respect to
any such litigation.

      The Advisory Agreement and the Subadvisory Agreement each were approved by
the Board of Trustees  (including  all of the Trustees  who are not  "interested
persons"  of  Heritage  or  Eagle,  as  defined  under the 1940 Act) and by Fund
shareholders  in compliance  with the 1940 Act. Each Agreement  provides that it
will be in force for an initial  two-year  period and it must be  approved  each
year  thereafter  by (1) a vote,  cast in person at a  meeting  called  for that
purpose,  of a majority of those  Trustees who are not  "interested  persons" of
Heritage,  Eagle, or the Trust,  and by (2) the majority vote of either the full
Board of  Trustees or the vote of a majority  of the  outstanding  shares of the
Fund. The Advisory and Subadvisory  Agreements each automatically  terminates on
assignment,  and each is terminable on not more than 60 days' written  notice by
the Trust to either party. In addition, the Advisory Agreement may be terminated
on not  less  than 60  days'  written  notice  by  Heritage  to the Fund and the
Subadvisory Agreement may be terminated on not less than 60 days' written notice
by  Heritage,  or 90 days'  written  notice  by  Eagle.  Under  the terms of the
Advisory   Agreement,   Heritage   automatically   become  responsible  for  the
obligations of Eagle upon termination of the Subadvisory Agreement. In the event
Heritage ceases to be the Fund's investment adviser or the Distributor ceases to
be the  Fund's  principal  distributor,  the  right  of  the  Fund  to  use  the
identifying name of "Heritage" may be withdrawn.

      Heritage and Eagle shall not be liable to the Fund or any  shareholder for
anything  done or omitted by them,  except acts or omissions  involving  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
imposed upon them by their  agreements  with the Fund or for any losses that may
be sustained in the purchase, holding or sale of any security.

      All of the officers of the Trust except for Messrs.  Alexander  and Zutz
are officers or directors of Heritage or its affiliates.  These  relationships
are described under "Management of the Fund."

      ADVISORY AND ADMINISTRATION  FEE. The annual investment  advisory fee paid
monthly by the Fund to Heritage is based on the Fund's  average daily net assets
as  listed  in the  Prospectus.  Heritage  has  voluntarily  agreed to waive its
management  fees to the extent that annual  operating  expenses  attributable to
Class A shares  exceed  1.65% of the  average  daily net assets or to the extent
that annual operating expenses attributable to Class B shares and Class C shares
exceed 2.40% of average daily net assets  attributable to that class during this
fiscal year.

      Heritage has entered into an  agreement  with Eagle to provide  investment
advice and portfolio  management services to the Fund for a fee paid by Heritage
to Eagle with respect to the amount of Fund assets under management equal to 50%
of the fees payable to Heritage by the Fund,  without regard to any reduction in
fees actually paid to Heritage as a result of expense limitations.

      CLASS-SPECIFIC EXPENSES. The Fund may determine to allocate certain of its
expenses  (in  addition to  distribution  fees) to the  specific  classes of the
Fund's shares to which those expenses are attributable.

      Brokerage Practices
      -------------------

      While the Fund generally purchases securities for long-term capital gains,
the Fund may engage in short-term  transactions  under various market conditions
to a greater  extent than certain  other  mutual  funds with similar  investment
objectives. Thus, the turnover rate may vary greatly from year to year or during
periods  within a year.  The  Fund's  portfolio  turnover  rate is  computed  by
dividing the lesser of purchases  or sales of  securities  for the period by the


                                      -18-
<PAGE>


average value of portfolio  securities for that period. The Fund's turnover rate
is expected to be 100%.

      Eagle  is   responsible   for  the  execution  of  the  Fund's   portfolio
transactions  and must  seek the most  favorable  price and  execution  for such
transactions.  Best execution,  however, does not mean that the Fund necessarily
will be paying the lowest commission or spread available.  Rather, the Fund also
will  take  into  account  such  factors  as size of the  order,  difficulty  of
execution, efficiency of the executing broker's facilities, and any risk assumed
by the executing broker.

      It is a common practice in the investment  advisory  business for advisers
of investment  companies and other institutional  investors to receive research,
statistical and quotation  services from  broker-dealers  who execute  portfolio
transactions  for the clients of such  advisers.  Consistent  with the policy of
most favorable price and execution,  Eagle may give  consideration  to research,
statistical  and other  services  furnished by brokers or dealers.  In addition,
Eagle may place  orders with  brokers who provide  supplemental  investment  and
market  research  and  securities  and  economic  analysis  and may pay to these
brokers a higher  brokerage  commission  or spread  than may be charged by other
brokers,  provided that Eagle  determines in good faith that such  commission is
reasonable in relation to the value of brokerage and research services provided.
Such research and analysis may be useful to Eagle in connection with services to
clients other than the Fund.

      The Fund may use the Distributor,  its affiliates or certain affiliates of
Heritage as a broker for agency  transactions  in listed and OTC  securities  at
commission  rates and under  circumstances  consistent  with the  policy of best
execution.  Commissions  paid to the  Distributor,  its  affiliates  or  certain
affiliates  of  Heritage   will  not  exceed  "usual  and  customary   brokerage
commissions."  Rule  l7e-1  under the 1940 Act  defines  "usual  and  customary"
commissions  to include  amounts that are  "reasonable  and fair compared to the
commission,  fee or  other  remuneration  received  or to be  received  by other
brokers in connection with comparable  transactions involving similar securities
being purchased or sold on a securities  exchange during a comparable  period of
time."

      Eagle also may select other brokers to execute portfolio transactions.  In
the OTC market,  the Fund  generally  deals with primary  market makers unless a
more favorable execution can otherwise be obtained.

      The  Fund  may  not  buy  securities  from,  or sell  securities  to,  the
Distributor as principal.  However, the Board of Trustees has adopted procedures
in  conformity  with Rule 10f-3 under the 1940 Act whereby the Fund may purchase
securities  that are  offered in  underwritings  in which the  Distributor  is a
participant. The Board of Trustees will consider the possibilities of seeking to
recapture  for  the  benefit  of  expenses  to the  Fund  of  certain  portfolio
transactions,  such as underwriting  commissions  and tender offer  solicitation
fees, by conducting such portfolio  transactions  through  affiliated  entities,
including  the  Distributor,  but only to the  extent  such  recapture  would be
permissible  under applicable  regulations,  including the rules of the National
Association of Securities Dealers, Inc.
and other self-regulatory organizations.

      Pursuant  to Section  11(a) of the  Securities  Exchange  Act of 1934,  as
amended,  the  Fund  has  expressly  consented  to  the  Distributor   executing
transactions on an exchange on its behalf.

      Distribution of Shares
      ----------------------

      The  Distributor  and  Financial  Advisors with whom the  Distributor  has
entered  into  dealer  agreements  offer  shares of the Fund as agents on a best
efforts  basis and are not obligated to sell any specific  amount of shares.  In
this connection,  the Distributor makes  distribution and servicing  payments to
participating  dealers  in  connection  with the  sale of  shares  of the  Fund.

Pursuant to the Distribution  Agreements with respect to Class A shares, Class B
shares and Class C shares,  the Distributor bears the cost of making information
about the Fund available through advertising,  sales literature and other means,
the  cost  of  printing  and  mailing   prospectuses   to  persons   other  than
shareholders,  and salaries and other expenses relating to selling efforts.  The
Distributor also pays service fees to dealers for providing personal services to
Class A, B and C shareholders and for maintaining shareholder accounts. The Fund
pays the cost of  registering  and qualifying its shares under state and federal
securities   laws  and  typesetting  of  its   prospectuses   and  printing  and
distributing prospectuses to existing shareholders.

      The Fund has adopted a Distribution  Plan for each class of shares (each a
"Plan" and  collectively  the  "Plans").  These Plans permit the Fund to pay the
Distributor  the  monthly  distribution  and  service  fee out of the Fund's net
assets to finance  activity that is intended to result in the sale and retention
of Class A shares,  Class B shares and Class C shares.  The Fund  intends to use
all  Class  A,  Class  B and  Class C 12b-1  fees  to pay the  Distributor.  The
Distributor,  on Class C shares, may retain the first 12 months distribution fee
for  reimbursement of amounts paid to the broker-dealer at the time of purchase.
Each Plan was  approved  by the Board of  Trustees,  including a majority of the
Trustees  who are not  interested  persons of the Trust (as  defined in the 1940
Act) and who have no direct or indirect  financial  interest in the operation of
the  Plan  or  the  Distribution  Agreement  (the  "Independent  Trustees").  In
approving such Plans, the Board determined that there is a reasonable likelihood
that the Fund and its shareholders will benefit from each Plan.

      Each Plan each may be terminated by vote of a majority of the  Independent
Trustees,  or by vote of a majority of the  outstanding  voting  securities of a
class of the Fund. The Board of Trustees  reviews  quarterly a written report of
Plan costs and the purposes for which such costs have been incurred.  A Plan may
be  amended  by vote of the  Board,  including  a  majority  of the  Independent
Trustees,  cast in person at a meeting called for such purpose.  Any change in a
Plan that would increase  materially the  distribution  cost to a class requires
shareholder approval of that class.

      The  Distribution  Agreements  may be  terminated  at any time on 60 days'
written  notice  without  payment of any penalty by either  party.  The Fund may
effect  such  termination  by  vote  of a  majority  of the  outstanding  voting
securities of the Fund or by vote of a majority of the Independent Trustees. For
so long as any Plan is in effect,  selection and  nomination of the  Independent
Trustees shall be committed to the discretion of such disinterested persons.

      The  Distribution  Agreements  and each Plan will  continue  in effect for
successive one-year periods, provided that each such continuance is specifically
approved  (1) by the vote of a majority of the  Independent  Trustees and (2) by
the vote of a  majority  of the  entire  Board of  Trustees  cast in person at a
meeting called for that purpose.

Administration of The Fund
- --------------------------

      ADMINISTRATIVE,  FUND  ACCOUNTING AND TRANSFER AGENT  SERVICES.  Heritage,
subject to the control of the Board of  Trustees,  will  manage,  supervise  and
conduct the  administrative  and business  affairs of the Fund;  furnish  office
space and equipment; oversee the activities of the subadviser and the Custodian;
and pay all  salaries,  fees and  expenses of officers and Trustees of the Trust
who are  affiliated  with  Heritage.  In  addition,  Heritage  provides  certain
shareholder servicing activities for Fund customers.

      Heritage also is the transfer and dividend  reimbursing agent for the Fund
and serves as fund accountant for the Fund. The Fund pays Heritage its cost plus
10% for its services as fund  accountant  and  transfer and dividend  disbursing
agent.

      CUSTODIAN.  State Street Bank and Trust Company,  P.O. Box 1912, Boston,
Massachusetts  02105,  serves as custodian of the Fund's assets. The Custodian
also provides portfolio accounting and certain other services for the Fund.

      LEGAL COUNSEL.  Kirkpatrick & Lockhart LLP, 1800  Massachusetts  Avenue,
NW, 2nd Floor, Washington, D.C. 20036, serves as counsel to the Trust.

      INDEPENDENT   ACCOUNTANTS.   Price  Waterhouse  LLP,  400  North  Ashley
Street,  Suite 2800, Tampa,  Florida 33602, is the independent  accountant for
the Trust.

POTENTIAL LIABILITY

      Under certain circumstances, shareholders may be held personally liable as
partners under  Massachusetts  law for  obligations of the Trust. To protect its
shareholders,  the  Fund has  filed  legal  documents  with  Massachusetts  that
expressly  disclaim the liability of its shareholders for acts or obligations of
the Fund. These documents  require notice of this disclaimer to be given in each
agreement, obligation or instrument the Fund or the Trustees enter into or sign.
In the unlikely  event a shareholder  is held  personally  liable for the Fund's
obligations,  that Fund is required to use its property to protect or compensate
the  shareholder.  On  request,  the Fund will defend any claim made and pay any
judgment against a shareholder for any act or obligation of the Fund. Therefore,
financial loss resulting from liability as a shareholder  will occur only if the
Fund itself  cannot  meet its  obligations  to  indemnify  shareholders  and pay
judgments against them.

COMMERCIAL PAPER RATINGS

The rating services'  descriptions of commercial paper ratings in which the Fund
may invest are:

Description of Moody's Investors Service, Inc. Commercial Paper Debt Ratings
- ----------------------------------------------------------------------------

PRIME-L.  Issuers  (or  supporting  institutions)  rated  PRIME-1  (P-1)  have a
superior  ability for  repayment  of senior  short-term  debt  obligations.  P-1
repayment   ability  will  often  be   evidenced   by  many  of  the   following
characteristics:  leading market positions in well-established  industries; high
rates of return on funds employed;  conservative  capitalization  structure with
moderate reliance on debt and ample asset protection;  broad margins in earnings
coverage  of  fixed  financial   charges  and  high  internal  cash  generation;
well-established  access to a range of financial  markets and assured sources of
alternate liquidity.

PRIME-2.  Issuers (or supporting institutions) rated PRIME-2 (P-2) have a strong
ability for repayment of senior short-term debt obligations.  This will normally
be evidenced by many of the characteristics cited above, but to a lesser degree.
Earnings  trends  and  coverage  ratios,  while  sound,  may be more  subject to
variation. Capitalization characteristics,  while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

Description of Standard & Poor's Commercial Paper Ratings
- ---------------------------------------------------------

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

A-2.   Capacity  for  timely   payment  of  issues  with  this   designation  is
satisfactory.  However,  the  relative  degree  of  safety is not as high as for
issues designated "A-1".

CORPORATE DEBT RATINGS

The rating  services'  descriptions  of corporate debt ratings in which the Fund
may invest are:

Description of Moody's Investors Service, Inc. Corporate Debt Ratings
- ---------------------------------------------------------------------

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

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

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

                                      A-1



<PAGE>


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

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

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

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

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

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

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

Description of Standard & Poor's Corporate Debt Ratings
- -------------------------------------------------------

AAA - Debt  rated AAA has the  highest  rating  assigned  by  Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

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

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

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

BB, B, CCC, CC, C - Debt rated "BB," "B," "CCC,"  "CC," and "C" is regarded,  on
balance,  as predominantly  speculative with respect to capacity to pay interest
and  repay  principal  in  accordance  with the  terms of the  obligation.  "BB"

                                      A-2



<PAGE>


indicates  the  lowest  degree  of  speculation  and "C" the  highest  degree of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures to adverse conditions.

BB - Debt  rated "BB" has less  near-term  vulnerability  to default  than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,   financial,  or  economic  conditions  that  could  lead  to
inadequate  capacity to meet timely  interest and principal  payments.  The "BB"
rating  category  is also  used for debt  subordinated  to  senior  debt that is
assigned an actual or implied "BBB-" rating.

B - Debt rated "B" has a greater  vulnerability to default but currently has the
capacity to meet interest payments and principal  repayments.  Adverse business,
financial,  or economic conditions will likely impair capacity or willingness to
pay interest and repay principal.  The "B" rating category is also used for debt
subordinated  to senior debt that is assigned an actual or implied "BB" or "BB-"
rating.

CCC - Debt rated "CCC" has a currently  identifiable  vulnerability  to default,
and is dependent upon favorable business,  financial, and economic conditions to
meet timely  payment of interest  and  repayment of  principal.  In the event of
adverse business,  financial,  or economic conditions,  it is not likely to have
the capacity to pay interest and repay  principal.  The "CCC" rating category is
also used for debt  subordinated  to senior  debt that is  assigned an actual or
implied "B" or "B-" rating.

CC - The rating "CC" is typically  applied to debt  subordinated  to senior debt
that is assigned an actual or implied "CCC" rating.

C - The rating "C" is typically applied to debt subordinated to senior debt that
is assigned an actual or implied "CCC-" debt rating.  The "C" rating may be used
to cover a  situation  where a  bankruptcy  petition  has been  filed,  but debt
service payments are continued.

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

D - Debt rated "D" is in payment  default.  The "D" rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace period. The "D" rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

PLUS (+) OR MINUS (-) - The  ratings  from "AA" to "CCC" may be  modified by the
addition  of a plus or minus  sign to show  relative  standing  within the major
categories.

NR -  Indicates  that no  public  rating  has  been  requested,  that  there  is
insufficient  information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

Item 27. Indemnification

         Article XI, Section 2 of Heritage  Series Trust's  Declaration of Trust
provides that:

         (a)      Subject to the exceptions and limitations contained in 
paragraph (b) below:

                  (i) every  person who is, or has been, a Trustee or officer of
the Trust (hereinafter  referred to as "Covered Person") shall be indemnified by
the  appropriate  portfolios  to the  fullest  extent  permitted  by law against
liability  and  against  all  expenses  reasonably  incurred  or  paid by him in
connection  with any  claim,  action,  suit or  proceeding  in which he  becomes
involved as a party or otherwise by virtue of his being or having been a Trustee
or  officer  and  against  amounts  paid or  incurred  by him in the  settlement
thereof;

                  (ii) the words  "claim,"  "action,"  "suit,"  or  "proceeding"
shall apply to all claims,  actions,  suits or proceedings  (civil,  criminal or
other,  including appeals),  actual or threatened while in office or thereafter,
and the words  "liability"  and "expenses"  shall include,  without  limitation,


                                      C-5
<PAGE>

attorneys' fees, costs, judgments, amounts paid in settlement,  fines, penalties
and other liabilities.

         (b) No indemnification shall be provided hereunder to a Covered Person:

             (i) who shall have been adjudicated by a court or body before which
the proceeding was brought (A) to be liable to the Trust or its  Shareholders by
reason of willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties  involved in the conduct of his office or (B) not to have acted in
good faith in the reasonable  belief that his action was in the best interest of
the Trust; or

             (ii)  in  the  event  of a  settlement,  unless  there  has  been a
determination   that  such   Trustee  or  officer  did  not  engage  in  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the  conduct of his office (A) by the court or other body  approving
the  settlement;  (B) by at least a majority of those  Trustees  who are neither
interested  persons  of the Trust nor are  parties  to the  matter  based upon a
review of readily available facts (as opposed to a full trial-type inquiry);  or
(C) by  written  opinion of  independent  legal  counsel  based upon a review of
readily  available  facts (as opposed to a full trial-type  inquiry);  provided,
however,  that any Shareholder may, by appropriate legal proceedings,  challenge
any such determination by the Trustees, or by independent counsel.

         (c) The  rights  of  indemnification  herein  provided  may be  insured
against by policies  maintained by the Trust,  shall be severable,  shall not be
exclusive of or affect any other  rights to which any Covered  Person may now or
hereafter be entitled,  shall  continue as to a person who has ceased to be such
Trustee or officer and shall inure to the  benefit of the heirs,  executors  and
administrators  of such a person.  Nothing  contained  herein  shall  affect any
rights to  indemnification  to which Trust  personnel,  other than  Trustees and
officers, and other persons may be entitled by contract or otherwise under law.

         (d) Expenses in connection with the  preparation and  presentation of a
defense to any claim,  action, suit, or proceeding of the character described in
paragraph  (a) of this Section 2 may be paid by the  applicable  Portfolio  from
time to time prior to final  disposition  thereof upon receipt of an undertaking
by or on behalf of such Covered Person that such amount will be paid over by him
to  the  Trust  if it is  ultimately  determined  that  he is  not  entitled  to
indemnification under this Section 2; provided, however, that:

              (i) such Covered Person shall have provided  appropriate  security
for such undertaking;

              (ii) the Trust is insured  against  losses arising out of any such
advance payments; or

              (iii) either a majority of the Trustees who are neither interested
persons of the Trust nor parties to the matter,  or independent legal counsel in
a written  opinion,  shall  have  determined,  based  upon a review  of  readily
available facts (as opposed to a trial-type inquiry or full investigation), that
there is reason to believe  that such Covered  Person will be found  entitled to
indemnification under this Section 2.


                                      C-6

         According to Article XII,  Section 1 of the  Declaration of Trust,  the
Trust is a trust, not a partnership.  Trustees are not liable  personally to any
person  extending  credit to,  contracting  with or having any claim against the
Trust,  a  particular  Portfolio or the  Trustees.  A Trustee,  however,  is not
protected from liability due to willful misfeasance, bad faith, gross negligence
or reckless disregard of the duties involved in the conduct of his office.

         Article XII,  Section 2 provides  that,  subject to the  provisions  of
Section 1 of Article  XII and to Article  XI,  the  Trustees  are not liable for
errors of  judgment  or  mistakes  of fact or law, or for any act or omission in
accordance with advice of counsel or other experts or for failing to follow such
advice.

         Paragraph 8 of the  Investment  Advisory and  Administration  Agreement
("Advisory  Agreement")  between  the  Trust and Eagle  Asset  Management,  Inc.
("Eagle"),  provides that Eagle shall not be liable for any error of judgment or
mistake of law for any loss suffered by the Trust or any Portfolio in connection
with the matters to which the Advisory  Agreement relate except a loss resulting
from  willful  misfeasance,  bad  faith or gross  negligence  on its part in the
performance  of its duties or from reckless  disregard by it of its  obligations
and duties  under the  Advisory  Agreement.  Any  person,  even  though  also an
officer, partner,  employee, or agent of Eagle, who may be or become an officer,
trustee, employee or agent of the Trust shall be deemed, when rendering services
to the  Trust or acting in any  business  of the  Trust,  to be  rendering  such
services  to or acting  solely  for the Trust  and not as an  officer,  partner,
employee,  or agent or one under the control or  direction  of Eagle even though
paid by it.

         Paragraph  9 of the  Subadvisory  Agreement  ("Subadvisory  Agreement")
between  Eagle and Martin  Currie  Inc.  ("Subadviser")  provides  that,  in the
absence of willful misfeasance, bad faith or gross negligence on the part of the
Subadviser,  or  reckless  disregard  of its  obligations  and duties  under the
Subadvisory  Agreement,  the Subadviser shall not be subject to any liability to
Eagle, the Trust, or their directors,  trustees,  officers or shareholders,  for
any act or  omission in the course of, or  connected  with,  rendering  services
under the Subadvisory Agreement.

         Paragraph 7 of the Distribution Agreement between the Trust and Raymond
James & Associates,  Inc.  ("Raymond  James") provides that, the Trust agrees to
indemnify,  defend and hold harmless  Raymond  James,  its several  officers and
directors,  and any person who  controls  Raymond  James  within the  meaning of
Section 15 of the  Securities  Act of 1933, as amended (the "1933 Act") from and
against any and all claims,  demands,  liabilities  and expenses  (including the
cost of investigating  or defending such claims,  demands or liabilities and any
counsel fees incurred in connection therewith) which Raymond James, its officers
or  Trustees,  or any such  controlling  person may incur  under the 1933 Act or
under  common law or otherwise  arising out of or based upon any alleged  untrue
statement of a material fact contained in the Registration Statement, Prospectus
or  Statement  of  Additional  Information  or arising  out of or based upon any
alleged  omission  to state a  material  fact  required  to be  stated in either
thereof or necessary to make the  statements in either  thereof not  misleading,
provided that in no event shall anything contained in the Distribution Agreement
be construed so as to protect  Raymond  James against any liability to the Trust
or its  shareholders to which Raymond James would otherwise be subject by reason
of willful misfeasance, bad faith, or gross negligence in the performance of its

                                      C-7
<PAGE>

duties,  or by reason of its reckless  disregard of its  obligations  and duties
under the Distribution Agreement.

         Paragraph  13 of the Heritage  Funds  Accounting  and Pricing  Services
Agreement  ("Accounting   Agreement")  between  the  Trust  and  Heritage  Asset
Management,  Inc.  ("Heritage")  provides that the Trust agrees to indemnify and
hold  harmless  Heritage  and its  nominees  from all  losses,  damages,  costs,
charges, payments, expenses (including reasonable counsel fees), and liabilities
arising  directly or indirectly  from any action that Heritage  takes or does or
omits to take to do (i) at the request or on the  direction of or in  reasonable
reliance on the written advice of the Trust or (ii) upon Proper Instructions (as
defined in the Accounting Agreement), provided, that neither Heritage nor any of
its nominees shall be  indemnified  against any liability to the Trust or to its
shareholders  (or any  expenses  incident  to  such  liability)  arising  out of
Heritage's own willful  misfeasance,  willful  misconduct,  gross  negligence or
reckless disregard of its duties and obligations  specifically  described in the
Accounting  Agreement  or its failure to meet the  standard of care set forth in
the Accounting Agreement.

Heritage Series Trust
880 Carillon Parkway
St. Petersburg, FL 33716

Ladies and Gentlemen:

         You have  requested  our opinion,  as counsel to Heritage  Series Trust
("Trust"),  as to certain matters regarding the issuance of Shares of the Trust.
As used in this letter,  the term "Shares" means the Class A, Class B, and Class
C shares of beneficial interest of the Heritage Series Trust - Aggressive Growth
Fund, a series of the Trust, during the time that  Post-Effective  Amendment No.
18 to the Trust's  Registration  Statement on Form N-1A ("PEA") is effective and
has not been superseded by another post-effective amendment.

         As such counsel,  we have examined certified or other copies,  believed
by us to be genuine,  of the Trust's  Declaration  of Trust and by-laws and such
resolutions  and minutes of meetings of the Trust's Board of Trustees as we have
deemed relevant to our opinion,  as set forth herein.  Our opinion is limited to
the laws and facts in existence on the date hereof, and it is further limited to
the  laws  (other  than  the  conflict  of law  rules)  in the  Commonwealth  of
Massachusetts that in our experience are normally  applicable to the issuance of
shares by  unincorporated  voluntary  associations  and to the Securities Act of
1933 ("1933  Act"),  the  Investment  Company  Act of 1940 ("1940  Act") and the
regulations of the Securities and Exchange Commission ("SEC") thereunder.

         Based on the foregoing,  we are of the opinion that the issuance of the
Shares has been duly  authorized by the Trust and that,  when sold in accordance
with the terms  contemplated by the PEA,  including receipt by the Trust of full
payment for the Shares and  compliance  with the 1933 Act and the 1940 Act,  the
Shares will have been validly issued, fully paid and non-assessable.

         We note,  however,  that the Trust 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 Trust.  The  Declaration  of Trust states that creditors of,
contractors  with and claimants  against the Trust or any series shall look only
to the  assets of the  Trust or the  appropriate  series  for  payment.  It also
requires that notice of such disclaimer be given in each note,  bond,  contract,
certificate  undertaking  or  instrument  made or issued by the  officers or the
trustees of the Trust on behalf of the Trust.  The  Declaration of Trust further
provides:  (1)  for  indemnification  from  the  assets  of  the  Trust  or  the
appropriate  series for all loss and expense of any shareholder  held personally
liable for the  obligations of the Trust or any series by virtue of ownership of
shares of the Trust or such series;  and (2) for the Trust or appropriate series

to assume  the  defense  of any claim  against  the  shareholder  for any act or
obligation of the Trust or series.  Thus,  the risk of a  shareholder  incurring
financial loss on account of shareholder  liability is limited to  circumstances
in which the Trust or series would be unable to meet its obligations.

         We hereby consent to this opinion accompanying the PEA when it is filed
with the SEC and to the  reference to our firm in the  statement  of  additional
information that is being filed as part of the PEA.

                                        Very truly yours,

                                        KIRKPATRICK & LOCKHART LLP
