                                  INTRODUCTION
 
   
     Many people recognize the desirability of accumulating an investment
portfolio through a planned long-range investment program, but find it difficult
to save the necessary money to make periodic stock purchases. AIM Summit
Investors Plans I (Plans) is designed to provide you an effective and convenient
method to create an investment fund for your future capital or income needs by
systematically investing a modest sum each month in shares of a mutual fund.
    
 
   
     Every Plan represents an agreement between yourself and State Street Bank
and Trust Company (Custodian) under which investments (after deduction of the
sales charge and custodian fees) are used to purchase shares of AIM Summit Fund,
Inc. (the Fund) at their net asset value. AIM Distributors, Inc. (AIM
Distributors or Sponsor) is the sponsor and principal underwriter of the Plans.
A Plan calls for fixed monthly investments for 15 years (180 investments). You
have the option to make additional monthly investments for up to a total of 25
years (300 investments). The front-end load (the Creation and Sales Charge) on
15 year Plans range from 8.50% on $9,000 Plans ($50.00 per month) to 1.00% on
$1,080,000 Plans ($6,000 per month) and from 9.61% to 1.01% of the net amount
invested, respectively. Total deductions (Creation and Sales Charges and
custodian fees) range from 13.00% (on $9,000 Plans) to 1.04% (on $1,080,000
Plans) of the net amount invested. These shares should be considered a long-term
investment and are not suitable if you are seeking quick profits or you might
not be able to complete a Plan. Since a major portion of the entire Creation and
Sales Charge is deducted from the first year's payment, withdrawal or
termination of an investment in the early years of a Plan will probably result
in a loss. For example, on a $9,000 Plan ($50 per month) deductions amount to
11.50% of the investments made if you complete the Plan. However, even after the
application of the refund privilege described on page 12, total deductions would
amount to 18% of total investments if you terminated the Plan at any time
between two months and 18 months. Moreover, if you continued the Plan for 19
months, total deductions would amount to 36.62% of total payments; they would
amount to 30.77% if you continued the Plan for two years. A detailed description
of all deductions appears on pages 5 and 6.
    
 
   
     Investments made through a Plan will not result in direct ownership of
Class I Shares of the Fund (Class I Shares). Your Plan represents an interest in
a trust which has direct ownership of the Class I Shares. You have a beneficial
interest in the underlying shares of the Fund. PLAN CERTIFICATES, ISSUED UNDER
PRIOR PROSPECTUSES, ARE NO LONGER PROVIDED. ALL PLANS ESTABLISHED ON OR AFTER
MARCH 1, 1995 ARE GOVERNED SOLELY BY THE RULES, RIGHTS, PRIVILEGES AND BENEFITS
SET FORTH IN THIS PROSPECTUS AS AMENDED FROM TIME TO TIME. YOU SHOULD RETAIN
THIS PROSPECTUS FOR FUTURE REFERENCE. All Plans established prior to March 1,
1995 are governed by the rules, rights, privileges and benefits set forth in the
applicable Plan Certificate.
    
 
   
     YOU HAVE THE RIGHT TO A 45 DAY REFUND OF YOUR INVESTMENT, AS WELL AS
CERTAIN OTHER LIMITED REFUND RIGHTS FOR CERTAIN PERIODS OF TIME AND UNDER THE
CONDITIONS DESCRIBED IN MORE DETAIL UNDER THE HEADING "CANCELLATION AND REFUND
RIGHTS" ON PAGE 12.
    
 
   
     The value of the Class I Shares will change when the values of the
securities in the Fund's portfolio change. A Plan calls for monthly investments
at regular intervals regardless of the value of the Class I Shares. You should
therefore consider your financial ability to continue a Plan. A Plan offers no
assurance against loss in a declining market. Terminating a Plan at a time when
the value of the Class I Shares then held is less than their cost will result in
a loss. Prepayment of all or part of the first year's investments in a Plan
increases the possible loss in the event of early termination. CLASS I SHARES OF
THE FUND ARE OFFERED TO THE GENERAL PUBLIC ONLY THROUGH AIM SUMMIT INVESTORS
PLANS I.

     As described in the attached Prospectus of the Fund, the Fund is an
open-end, diversified investment company whose objective is capital growth.
Although the Fund may purchase income-producing securities, income will
generally not be a consideration in the selection of securities for the Fund's
portfolio. Ownership of Class I Shares through a Plan provides you with several
advantages:
    
 
          (1) Diversification -- By pooling the money invested by many
     investors, the Fund will be able to reduce (but not eliminate) risk by
     diversifying its holdings among many securities in order to minimize the
     portfolio impact of any single investment.
 
          (2) Economics of Size -- Purchases and sales of securities often
     entail disproportionately large unit costs on small transactions. The size
     and volume of the Fund's portfolio transactions should enable it to effect
     such transactions at better net unit prices than an individual could
     achieve.
 
   
          (3) Professional Management -- Investors may benefit from the
     full-time skill and attention of professional managers.
    
 
   
     The Plans contain a Creation and Sales Charge equal to as much as 50% of
the first 12 investments and lesser amounts of subsequent investments. In
addition to the Creation and Sales Charge, you must pay custodian fees and
incidental service fees to the Custodian and service charges to the Sponsor. See
"Custodian and Sponsor Charges."
    
 
   
     For Plans established after May 1, 1993, a Plan may be terminated by the
Custodian or Sponsor if you fail to make investments under your Plan for a
period of 6 months. For Plans established prior to May 1, 1993, a Plan may be
terminated by the Custodian or Sponsor if you fail to make investments under
your Plan for a period of 12 months. Both types of Plans may be terminated if
Class I Shares are not available and a substitution is not made. See
"Termination of a Plan" at page 20.

  (B) The 25-year investment schedule reflects the charges applicable to a
      15-year Plan which is continued under the Extended Investment Option. The
      Custodian fee may be increased as set forth on page 11.
    
 
   
     Dividends and distributions received on Class I Shares during the periods
shown above have not been included or reflected in any way in the amounts shown
in the table. Amounts available for dividends and distributions take into
account expenses of the Fund.
    
 
   
     After the first twelve payments, the Creation and Sales Charge deducted
from any investment will not exceed 5.86% of the net investment in Class I
Shares (before deduction of Custodian fee).
    
 
     The amounts shown are also subject to an additional Custodian Charge of
$2.50 (plus transfer taxes, if any) if the Plan is terminated prior to
completion of all Plan investments.

                              HOW TO START A PLAN
    
 
   
     To start a Plan, you must complete an application and mail it to AIM
Distributors, together with a check. Your check should be in the amount of your
initial monthly investment unit and payable to State Street Bank and Trust
Company, Custodian. After your application has been accepted, you will be issued
a Plan and receive a statement showing the number of Class I Shares purchased
for your account. You will then send regular monthly investments, made payable
to the Custodian, directly to the Custodian's administrative service agent,
Boston Financial Data Services, Inc. (BFDS), P.O. Box 8300, Boston,
Massachusetts 02266-8300. Investments, after applicable deductions, will be
applied toward the purchase of Class I Shares at their net asset value.
    
 
                      RIGHTS AND PRIVILEGES OF PLANHOLDERS
 
   
     All Plans are registered in your name at the time of issuance and
constitute an individual agreement among you, the Sponsor and the Custodian.
Although the Sponsor and Custodian may make amendments to the Custodian
Agreement which do not adversely affect you, no agent or other person can
otherwise change the terms of your Plan, or bind the Sponsor, BFDS, the
Custodian or the issuer of the Class I Shares by any statement, written or oral,
not contained in this Prospectus. Under the terms of the Plan, you enjoy certain
rights, privileges and options which are described as follows:
    
 
1. REINVESTMENT OF INCOME DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
 
   
     Unless otherwise directed by you, all income dividends and capital gains
distributions, in whatever form received and after applicable deductions, are
automatically used to purchase additional Class I Shares at net asset value. No
sales charge is made on any such reinvestment. You may instruct BFDS by written
notice, received at least seven days prior to the record date of an income
dividend or capital gains distribution, to remit the net amount of such dividend
or distribution to you. You may change these directions at any time. You must
reinvest dividends and distributions for qualified retirement plans, including
Individual Retirement Accounts ("IRAs"), unless you are age 59 1/2 or older.
    
 
   
     You need to report dividends and distributions paid by the Fund for income
tax purposes, whether they are invested in additional Fund shares or paid in
cash. (Qualified retirement plans, including IRAs, may be entitled to defer
taxes until some later date.)
    
 
2. RIGHTS OF ACCUMULATION
 
   
     Any person may combine the face amounts of two or more Plans purchased at
one time to take advantage of the lower Creation and Sales Charges available on
larger sized investments. The term "any person" includes an individual, his or
her spouse and children under the age of 21, and a trustee or other fiduciary of
a single trust estate or a single fiduciary account (including a pension,
profit-sharing or other employee benefit trust created pursuant to a plan) even
though more than one beneficiary is involved. The term any person does not
include a group of individuals whose funds are combined, directly or indirectly,
for the purchase of redeemable securities of a registered investment company
whether jointly or through a trustee, agent, custodian or other representative
for such a group of individuals.
    
 
                                        8
<PAGE>   11
 
   
     To qualify for the reduced Creation and Sales Charges, you must submit all
of the applications for the Plans involved at the same time and include a letter
from you (or your dealer) requesting that the face amounts of your Plans be
aggregated for the purpose of determining the applicable Creation and Sales
Charges. If you discontinue investments under one or more of your Plans, the
remaining Creation and Sales Charges will be changed to reflect the charges
applicable to the Plans that remain in effect.
    
 
     When purchasing any new Plan(s), any person (as defined above) may
qualify for a reduced Creation and Sales Charge by combining the face amount of
any existing Plan(s) on which investments are current with the face amount of
the new purchase. When increasing the face amount of any existing Plan(s) on
which investments are current, "any person" (as defined above) may qualify for a
reduced Creation and Sales Charge applicable to the value of the changed Plan.
For rights of accumulation, a Plan is considered to be current if: (a) it has
been completed and not redeemed; (b) it has not been completed but has at least
as many investments recorded as there are months elapsed since establishment or
since being increased; or (c) it is a qualified retirement plan, including an
IRA. The reduced Creation and Sales Charges apply to payments made after the
Sponsor has been notified of the eligibility of such Plans for reduced Creation
and Sales Charges and has received the information necessary to confirm such
eligibility. In the case of existing IRA Plans at the $166.66 per month level,
the reduced Creation and Sales Charges will apply to payments made on both the
existing Plan and the new Plan.
 
3. FEDERAL INCOME TAX WITHHOLDING
 
   
     As an additional service, BFDS may withhold 28% of any income dividend or
capital gains distribution by the Fund and send that amount to the Internal
Revenue Service as a credit against your tax liability, if any. The amount
withheld may or may not be equal to the additional taxes you may owe due to the
dividend or distribution. The withholding service, however, is only available to
you if you reinvest your distributions in full. If you elect to authorize this
withholding, the number of Class I Shares purchased with the remainder of the
income dividend or capital gains distribution will be less than would have
otherwise been the case.
    
 
   
     This service is available with respect to all Plans except qualified
retirement plans, including IRAs. You may initiate this option upon written
request to BFDS. Once initiated, the withholding remains in effect until you
notify BFDS in writing to terminate the withholding.
    
 
4. VOTING RIGHTS
 
   
     You will receive a notice and related proxy statement for each meeting of
the Fund's shareholders. The Custodian will vote the shares held in your account
as you instruct on the voting instructions card which will accompany the notice
and proxy statement. If the voting instructions card is validly executed and
returned without specification of a choice, the shares will be voted in favor of
the proposals of the Fund's management. The Custodian will vote shares for which
no valid voting instructions have been received in the same proportion as it
votes shares for which it has received instructions. You may attend any such
meetings, and if you desire to vote in person the shares held in your account,
you may make a written request to the Custodian prior to the meeting for a proxy
which will permit the shares to be voted in person.
    
 
                                        9
<PAGE>   12
 
5. STATEMENTS, REPORTS AND NOTICES
 
   
     BFDS will mail to you a statement for each investment stating the price per
Class I Shares purchased after applicable deductions and the total number of
Class I Shares held for your account. A notice of the next investment due is
also included. You will also receive at least annually a current Fund prospectus
and audited financial statements of the Fund, including a complete list of all
securities held in the Fund's portfolio, and copies of all other reports sent by
the Fund to its shareholders. You will also be sent notices of all income
dividends and capital gains distributions made with respect to Class I Shares,
together with tax reporting information relating to such dividends and
distributions. Any notices, reports or documents required or authorized to be
given or sent to you under this Prospectus will be conclusively deemed to have
been given or sent upon mailing to your address of record, and the date of such
mailing will be deemed the date of the giving of such notice.
    
 
6. RETIREMENT PLANS
 
   
     You may use a Plan to establish tax-deferred qualified retirement plans
such as IRAs, IRA-SEPs, Profit Sharing Plans and Money Purchase Plans. Detailed
information concerning such plans is available from the Sponsor. The information
sets forth the additional service fees charged for such retirement plans. The
annual maintenance fee charged by the Custodian for plans offered by the Sponsor
is $10.00. The $10.00 fee will be deducted from plan shares unless it is paid in
advance. In addition, IRA rollover or transfer contributions can be accepted
into a Plan for qualified individuals. However, a tax-deferred qualified
retirement plan may not be established by changing the registration of an
existing plan.
    
 
7. PRE-AUTHORIZED CHECK INVESTMENT PROGRAM
 
   
     If you wish to have investments in your Plan made automatically without
having to write a check each month, you may request that investments be made by
means of pre-authorized checks. Under this program, each month BFDS will draft
your bank account in the amount of the monthly payment. In addition, for U.S.
military personnel, you may choose to have investments in your Plan made
automatically through a government allotment. The proceeds of the draft (less
applicable Creation and Sales Charges and other applicable fees and charges)
will be invested in your account.
    
 
   
     To initiate a Pre-Authorized Check Investment Program, or government
allotment you should complete the appropriate forms and forward them to BFDS.
You may terminate a Pre-Authorized Check Investment Program at any time by
written notice to BFDS at least five days prior to the date of the next
scheduled draft.
    
 
8. TRANSFER OR ASSIGNMENT
 
   
     To secure a loan, you may assign your right, title and interest in a Plan
to a bank or other lending institution. (Qualified retirement plans, including
IRAs, are required by federal tax law to be non-assignable.) The bank or other
lending institution, however, will not be entitled to exercise the right of
partial withdrawal or partial liquidation. During the term of the assignment,
you will be entitled to all dividends and distributions on Class I Shares. In
addition, you may:
    
 
   
          (a) transfer your right, title and interest to another person whose
     only right shall be the privilege of complete withdrawal from the Plan; or
    
                                       10
<PAGE>   13
 
   
          (b) transfer your right, title and interest to another person, trustee
     or custodian acceptable to the Sponsor, who has made application to the
     Sponsor for a similar Plan.
    
 
     A charge of $2.50 is made for each such transaction plus transfer taxes,
where applicable.
 
   
     The Custodian will, at the request of the assignee, record an assignment
until such time as the assignee notifies BFDS that the assignment has been
released. No such assignment will be binding on the Custodian until it is
recorded. Until the Custodian and the Sponsor have permitted such assignment to
be recorded, they may treat you as the sole and absolute owner of the Plan and
the related Class I Shares.
    
 
9. ACCELERATION OF INVESTMENTS
 
   
     You may complete a Plan ahead of schedule by making investments in advance
of their due dates; but you may make no more than 24 investments in one calendar
year including any monthly investments. In addition to these advance
investments, you may make an additional 24 investments which may be made
initially or at any one time during the life of the Plan. You may accrue and pay
investments in a lump sum. These preinvestments provision may be waived only
(a) to make a Plan that is in arrears current, (b) for a transfer of assets from
a tax-sheltered retirement plan to a Fund tax-sheltered retirement plan, or (c)
if the Planholder dies, to allow the Plan to be completed at one time by the
estate or beneficiary. The Creation and Sales Charges are not reduced for
accelerated investments. However, on multiple investments, the Custodian fee
cannot exceed $5.00. See "Custodian Fees."
    
 
10. CHANGING THE FACE AMOUNT OF A PLAN
 
   
     You may increase the amount of your Plan at any time. In addition, prior to
making the sixth investment under a Plan, you may decrease the amount of your
Plan by as much as 50% of the face amount. You should send requests for changes
in the face amount of your Plan and a completed Plan application for the new
face amount to AIM Distributors. The new Plan must be in one of the
denominations listed on page 5. An increase in a Plan amount does not create new
cancellation and refund rights that are created when a new Plan is issued. The
Creation and Sales Charges already paid on the existing Plan will be recomputed
and applied as a credit to the Creation and Sales Charges due on the new Plan at
the time that it is established. Any additional Creation and Sales Charges due
on the new Plan will be obtained from a liquidation of Class I Shares. The
Custodian will charge $2.50 for any change in a Plan denomination and for any
applicable transfer taxes. For a period of twelve months following a face change
increase, you may decrease the increased Plan to a smaller plan size, but not
smaller than the original Plan prior to the increase. Investments already made
will be credited to the new Plan.
    
 
11. EXTENDED INVESTMENT OPTION
 
   
     You may continue making monthly investments pursuant to the Extended
Investment Option after completing all scheduled investments under your Plan.
Investments under this option are subject to the same deductions as applied to
the last scheduled investment (except that the Custodian may increase the
Custodian fee applicable during this period to the rate then being charged for
new Plans of the same denomination, but not greater than 75% higher than the
Custodian fees detailed in this Prospectus). You may stop all future investments
under this option
    
                                       11
<PAGE>   14
 
   
by notifying BFDS in writing, after which no additional investments will be
permitted and the Plan will be deemed completed. If you fail to make regularly
scheduled investments, under this option, for six consecutive months after being
credited for any advance investments made under the option, you forfeit the
right to make additional investments, and for Plans established after May 1,
1993 the Plan may be terminated by the Sponsor or the Custodian. For Plans
established prior to May 1, 1993, the Plan may be terminated if you fail to make
regularly scheduled investments for 12 consecutive months. The Sponsor and
Custodian will not require termination of an Extended Investment Option until
you make the 300th payment under your Plan even if such payment is more than 25
years from the issuance date.
    
 
   
     When the Extended Investment Option expires either through failure to make
required monthly investments or upon written notice of termination to BFDS or
for any other reason, the Custodian may increase its fee to the rate then
currently being charged for new Plans of the same denomination. In no case,
however, will this new rate be more than 75% higher than the current annual rate
of the Custodian fees.
    
 
12. SYSTEMATIC WITHDRAWAL PROGRAM
 
   
     When you complete all regularly scheduled investments, you may choose to
establish a Systematic Withdrawal Program. If you are holding Plans in IRAs,
Keogh plans, or other retirement plans you may choose to establish a Systematic
Withdrawal Program by notifying the Sponsor that you do not intend to make any
further Plan payments. Under this program, you may choose to receive monthly or
quarterly checks in any amount of $50 or more. To provide funds for these
payments, the Custodian, as your agent, will on the first business day of each
month or quarter redeem shares held in your account at the net asset value of
the Fund in effect at the time of each such redemption. You may change the
amount of payments made to you under a Systematic Withdrawal Program or
discontinue a Systematic Withdrawal Program at any time.
    
 
   
     While a Systematic Withdrawal Program is in effect, you may not elect to
receive dividends and distributions, in cash, on Class I Shares held in your
account. You may not simultaneously maintain an uncompleted Plan and a
Systematic Withdrawal Program.
    
 
   
     The IRS considers payments you receive under a Systematic Withdrawal
Program as a taxable transaction. Since such payments are funded by the
redemption of shares of the Fund, they will be treated for tax purposes as a
sale or exchange of a capital asset, resulting in the recognition of a capital
gain or loss, rather than as ordinary income.
    
 
   
     A charge of $1.00 per check will be made for each payment under a
Systematic Withdrawal Program. This charge is collected by redeeming the
necessary fractional shares. For any payment made ten years after the issuance
of a Plan, the charge may be increased to the amount specified in the then
current Prospectus. However, this charge may not exceed $1.75. The Sponsor may
(upon 90 days' notice to you) discontinue offering Systematic Withdrawal
Programs.
    
 
13. CANCELLATION AND REFUND RIGHTS
 
   
     You have certain rights of cancellation. Within 60 days after issuance of
the Plan, the Sponsor will send to you a notice regarding your cancellation
rights. If you elect to cancel your Plan, you must submit a written request to
BFDS so that it is received within 45 days after the mailing of that notice. You
will receive a cash refund equal to the sum of (1) the total current net asset
    
   
value of the
    
                                       12
<PAGE>   15
 
   
Class I Shares credited to your Plan account on the date that the cancellation
request is received by BFDS and (2) an amount equal to the difference between
the total investments made under the Plan and the net amount invested in Class I
Shares.
    
 
   
     In addition, you may submit a written request to BFDS at any time within an
18-month period beginning on the date of the issuance of the Plan and receive
from the Sponsor a cash payment equal to the sum of (1) the total current net
asset value of the Class I Shares credited to the account on the date of
redemption and (2) the amount by which the Creation and Sales Charges deducted
from the Planholder's total investments exceed 15% of the investments made up to
the date of redemption. Custodian fees and service charges are not refundable.
    
 
   
     In order to receive the above refunds, your request should be sent in
writing, with the signature guaranteed, as required by the Custodian, to Boston
Financial Data Services, Inc., P.O. Box 8300, Boston, Massachusetts 02266-8300.
    
 
   
     For Plans established after May 1, 1993, the Sponsor will send you a
written notice of the 18-month right of cancellation if either of the following
occurs: (a) if during the first 15 months after the date of issuance of the
Plan, you have missed three investments or more; or (b) if following the first
15 months after the date of issuance of the Plan (but prior to 18 months after
such date), you have missed one investment or more. If the Sponsor has
previously sent a notice in connection with event (a) above, a second notice
will not be sent even if additional investments are missed. These notices will
inform you of your Plan cancellation rights as set forth above, and also will
include the value of the account and the amount you would be entitled to receive
upon cancellation, as of the date of the notice.
    
 
   
     For Plans established prior to May 1, 1993, the Sponsor will send you a
notice within 30 days following the expiration of 15 months after the date of
the issuance of the Plan Certificate if you have missed three investments or
more. The Sponsor will also send you a notice (described above) if you have
missed one investment or more after the expiration of the 15 month period but
prior to the expiration of the 18 month period. These notices will inform you of
your rights of cancellation as set forth above, of the value of your account at
the time the notice is sent and of the amount to which you are entitled if you
choose to redeem your Plan.
    
 
14. PARTIAL WITHDRAWAL OR PARTIAL LIQUIDATION WITHOUT TERMINATION
 
   
     If you wish to withdraw part of your investment in your Plan without
terminating your Plan, you may do so either by written instruction to the
Custodian, or by calling BFDS at (617) 483-5000, subject to the restrictions
specified below.
    
 
   
     If you wish to receive cash instead of Class I Shares, you may direct the
Custodian, acting as your agent, to withdraw and then redeem (liquidate) part of
your shares and remit the net proceeds to you, again subject to the restrictions
specified below. When a partial liquidation has been effected through the
redemption of Class I Shares by the Custodian, you may, but are not required to,
restore the value of your Plan by remitting to BFDS an amount equal to the cash
withdrawal, which amount will be used to purchase Class I Shares for your
account at the next determined net asset value of the Class I Shares. This
restoration cannot be made earlier than 90 days (45 days for Individual
Retirement Accounts) following a partial liquidation. All reinvestments must be
at least 25% of the amount withdrawn or $2,000, whichever is less. There may be
federal income tax consequences upon a partial liquidation of Class I Shares.
Restoration of a partial liquidation of IRA shares must be
    
                                       13
<PAGE>   16
 
   
made within 60 days in order to avoid tax consequences, including early
withdrawal penalties. See "Taxes." You may, however, make a partial withdrawal
and reinvestment in a manner which complies with the Internal Revenue Code rules
relating to IRA rollovers.
    
 
   
     The partial liquidation and restoration privilege is intended to enable you
to use funds invested in a Plan for temporary or emergency purposes. The Sponsor
may limit you to exercising the partial liquidation and restoration privilege
once during the period of a calendar year, although the Sponsor currently does
not enforce this limit. The Sponsor may also impose such additional restrictions
as, in its judgment, are necessary to conform to the requirements of Section
2830 of the National Association of Securities Dealers' Conduct Rules.
    
 
   
     A partial withdrawal or liquidation will only be allowed if you have owned
your Plan for at least 45 days. The number of Class I Shares involved cannot
exceed 90% of the shares in your account and the amount involved must be at
least $100. A charge of $2.50 will be made by the Custodian for each partial
withdrawal, liquidation or restoration, and you will be liable for any transfer
taxes that may be required. Restorations of amounts you withdraw as a partial
liquidation should be clearly identified as such, in order to distinguish them
from additional payments. A partial withdrawal or liquidation will not affect
the total number of Plan investments, the period in which such investments are
to be made, or the unpaid balance of Plan investments under your Plan.
    
 
   
     You may also request partial withdrawals or partial liquidations by
telephone by calling BFDS at (617) 483-5000. If you do not wish to allow
withdrawals by telephone by any person in your account, you should decline that
option on the account application. You may use the telephone withdrawal or
liquidation feature only if: (a) the proceeds are made payable to the planholder
of record and mailed to the address of record; (b) there has been no change of
address of record on the account within the preceding 30 days; (c) you can
provide proper identification information; and (d) the proceeds of the
withdrawal do not exceed $50,000. The Cancellation and Refund Rights set forth
on page 12 or Complete Withdrawal or Termination on page 15 of this Prospectus
may not be exercised by telephone.
    
 
   
     Shares held in retirement plans (such as IRA and IRA/SEP) or 403(b) plans
are not eligible for the telephone withdrawal option. AIM Distributors has made
arrangements with certain dealers to accept telephone instructions for the
withdrawal of shares. AIM Distributors may impose conditions on these dealers,
including the condition that they enter into agreements (which contain
additional conditions with respect to the withdrawal of shares) with AIM
Distributors. The Fund, AIM Distributors, the Custodian, and BFDS will not be
liable for any loss, expense or cost arising out of any telephone withdrawal
request effected in accordance with the authorization set forth at that item of
the account application if they reasonably believe such request to be genuine,
but may in certain cases be liable for losses due to unauthorized or fraudulent
transactions if they do not follow reasonable procedures for verification of
telephone transactions. Such reasonable procedures may include recording of
telephone transactions, requests for confirmation of the Planholder's Social
Security Number and current address, and mailings of confirmations promptly
after the transaction.
    
 
   
     Shares withdrawn by telephone are redeemed at their net asset value next
determined after a request for withdrawal in proper form is received by BFDS.
Orders for the withdrawal of shares received in proper form prior to the New
York Stock Exchange ("NYSE") close on any business day of the Fund will be
confirmed at the price determined as of the close of that day. Any loss
resulting from the dealer's failure to submit a request for withdrawal within
the prescribed time
    
 
                                       14
<PAGE>   17
 
   
frame will be borne by that dealer. Telephone withdrawal requests must be made
by NYSE close on any business day of the Fund and will be confirmed at the price
determined as of the close of that day. No telephone withdrawal request will be
accepted which specifies a particular date for withdrawal or which specifies any
special conditions.
    
 
     See "Complete Withdrawal or Termination" below for information concerning
the method of providing written instructions to the Custodian to effect a
partial withdrawal or liquidation and the circumstances under which the
redemption of shares may be delayed.
 
15. COMPLETE WITHDRAWAL OR TERMINATION
 
   
     You may terminate your Plan at any time upon written request to BFDS. In
terminating your Plan you may request the Custodian to deliver to you in
certificate form the Class I Shares you have accumulated (properly registered in
your name) or you may direct the Custodian, as your agent, to withdraw your
shares, redeem (liquidate) them and send you the proceeds. A charge of $2.50
will be made by the Custodian for a complete withdrawal, and you will be liable
for any transfer taxes that may be required. If you direct the delivery of your
Class I Shares, sufficient shares will be redeemed to pay authorized deductions
and transfer taxes and leave no fractional shares, with any net balance to be
paid in cash. The redemption of Class I Shares is a taxable event. See "Taxes."
    
 
   
     Instructions in writing for both partial or full liquidation of Class I
shares held in a Plan must be in the form of a letter signed by you with your
signature guaranteed, as required by the Custodian. A signature guarantee is
designed to protect you, the Plan, the Sponsor and the Custodian. Acceptable
guarantors are banks, broker-dealers, savings and loan associations, credit
unions, national securities exchanges and any other "eligible guarantor
institution" as defined in rules adopted by the Securities and Exchange
Commission (the "SEC"). A notary public is not an acceptable guarantor. The
Sponsor currently does not require signature guarantees for liquidation requests
of $50,000 or less unless the proceeds are to be paid to a person other than the
record owner or are to be sent to an address other than the one of record. Upon
notice to you, this policy may be changed. Currently, in addition to these
requirements, if you have invested in the Plan to establish an IRA, you should
include the following information along with your written request for either
partial or full liquidation of Class I Shares: (a) a statement as to whether or
not you have attained age 59 1/2; (b) a statement as to whether or not you are
legally disabled; (c) a statement as to whether or not you elect to have federal
income tax withheld from the proceeds of the liquidation; and (d) your Social
Security number along with the following statement: "I certify under penalties
of perjury that the Social Security number provided is correct and that I am not
subject to backup withholding either because I am exempt from backup
withholding, I have not been notified by the Internal Revenue Service that I am
subject to backup withholding, or the Internal Revenue Service has notified me
that I am no longer subject to backup withholding." If you have been notified by
the Internal Revenue Service that you are currently subject to backup
withholding, then you should modify the preceding statement accordingly. Even if
you elect not to have federal income tax withheld, you are liable for federal
income tax on the taxable portion of the liquidation. You may also be subject to
tax penalties under the estimated tax payment rules if your payments of
estimated tax and withholding, if any, are not adequate. All documents must be
in proper order before any liquidation can be executed. You should send
liquidation requests to BFDS. The redemption price will be the net asset value
of Class I Shares next determined after AIM Distributors or BFDS receives such
documents in proper order.
    
 
                                       15

     Except as set forth below, you will be sent the proceeds of a partial or
complete liquidation within seven days after BFDS receives all necessary
documents in proper order. However, BFDS will not mail redemption proceeds to
you until checks received for any shares purchased by you have cleared. The
payment period may be extended if the Custodian's right to redeem shares of the
Fund has been suspended or restricted because: (a) trading on the NYSE is
restricted, as determined by the applicable rules and regulations of the SEC;
(b) the NYSE is closed for other than customary weekend and holiday closings;
(c) the SEC has by order permitted such suspension; or (d) an emergency as
determined by the SEC exists making disposition of portfolio securities or the
valuation of the net assets of the Fund not reasonably practicable.
    
 
16. PLAN REINSTATEMENT PRIVILEGE
 
   
     You may, within 90 days after you have completely terminated your Plan as
described in paragraph 15 above, by written request to BFDS, reinstate your Plan
without any sales charge, subject to certain restrictions:
    
 
   
          A. By including with the request an amount which is 10% or more of the
     redemption proceeds, if no refunded sales charges were provided in the
     termination.
    
 
   
          B. By including with the request the full amount of all refunded sales
     charges, plus an amount equal to 10% or more of the shares redeemed, if the
     termination was done under the privileges described in paragraph 13, page
     12.
    
 
   
     You may not reinstate a terminated plan if you have ever exercised the
privilege previously. If you exercise the Plan Reinstatement Privilege, neither
the total number of monthly investments to be made nor the unpaid balance of
monthly Plan investments under the Plan will be affected.
    
 
   
     The complete termination of your Plan will normally result in the
realization of gain or loss for federal income tax purposes depending upon your
basis for your terminated Plan. Any gain will be recognized and subject to the
applicable capital gains tax; however, if a loss were realized, reinstatement of
your Plan, within 30 days after termination, could effect a "wash sale," in
which event the loss will not be recognized for tax purposes. The amount of the
non-recognized loss will however, be added to the cost of the reinstated Plan to
determine your basis for tax purposes.
    
 
   
     In addition to the Plan Reinstatement Privilege described above, the
Sponsor may from time to time permit planholders who have previously terminated
their Plans to establish new Plans on the following terms:
    
 
          1. The Planholder must open the new Plan with an investment equal to
     or less than the amount of the redemption proceeds received upon
     liquidation of the former Plan. No Creation and Sales Charges or Custodian
     fees will be subtracted from the initial investment.
 
          2. The number of the next payment due on the new Plan will be the
     number of the next payment due on the former Plan at the time it was
     terminated.
 
          3. Creation and Sales Charges on the new Plan will be the Creation and
     Sales Charges that would currently be applicable to the former Plan.
 
     The ability to establish such new Plans will not be generally available,
but will be available only during such limited time periods as may be specified
by the Sponsor from time to time.
 
                                       16
<PAGE>   19
 
17. CONTINUATION OF CUSTODIANSHIP
 
   
     If, after you have completed your Plan investments, you do not elect a
complete or partial withdrawal of your investment in your Plan or termination of
your Plan, then the Custodian will retain custody of the Class I Shares
(provided there is no substitution of Class I Shares, as discussed below) and
will continue to perform all of its services until after the 300th payment under
your Plan has been made. You may, however, elect to continue the Custodianship
after the 300th payment under the Plan, subject to the right of the Sponsor or
Custodian to terminate the Plan.
    
 
                         CUSTODIAN AND SPONSOR CHARGES
 
CREATION AND SALES CHARGES
 
   
     The Sponsor receives the Creation and Sales Charges as compensation for its
services and costs in creating the Plans and arranging for their administration,
for making the Class I Shares available to you at their net asset value and for
all selling expenses and commissions with respect to the Plans. These charges
are deducted from each investment you make and are larger on the first year's
investments than on subsequent investments. For example, on a $50 per month
Plan, $25.00 is deducted from each of the first 12 investments you make during
the first year. After the first year, the charge drops to $2.77 per investment.
    
 
   
     During the fiscal years ended October 31, 1998, 1997 and 1996, total
investments made by all planholders amounted to $216,452,620, $123,758,764 and
$118,046,016, respectively. The amount of Creation and Sales Charges deducted
from these investments was $8,074,777, $7,565,209 and $7,099,870, respectively,
of which amount $597,753, $572,877 and $542,980, respectively, was retained by
the Sponsor and $7,477,024, $6,992,332 and $6,556,890, respectively, was paid to
investment dealers who participated in the sale of Plans.
    
 
     Plans may be purchased directly from the Sponsor and investments may be
made thereunder without deduction of Creation and Sales Charges by directors,
officers and full-time employees of the Fund and the Sponsor and its affiliates.
The Sponsor foregoes the Creation and Sales Charges on Plans purchased by such
persons because any expenses incurred by it in connection with such purchases
are expected to be minimal.
 
CUSTODIAN FEES AND SERVICE CHARGES
 
   
     For its services under your Plan, the Custodian deducts $1.50 per
investment you make as a service fee. This fee is deducted from Plan investments
prior to the purchase of Class I Shares. The Custodian fee charged at any one
time may not exceed $5.00. Thus, if you submit four or more investments at one
time, the aggregate Custodian fee deducted from all such investments will be
$5.00.
    
 
   
     After the completion of all Plan investments, or, if investments have been
made in advance, after the expiration of 15 years from the date of the Plan
(provided you have not exercised the Extended Investment Option), the Custodian
receives for its services an annual fee of $12.00. The Custodian also deducts
this fee on Plans on which no investment has been made for a 12-month period.
This fee will normally be deducted from the first combined income dividend and
capital gains distribution in each year, but the Custodian may to collect these
fees from the proceeds of the sale of Class I Shares held for your account, if
necessary.
    
                                       17
<PAGE>   20
 
   
     The aggregate amount of Custodian fees deducted by the Custodian with
respect to all Plans during the fiscal year ended October 31, 1998 was
$1,579,199.
    
 
   
     Each year the Custodian will deduct from your account an amount necessary
to reimburse actual expenses (such as postage, forms and envelopes) incurred by
the Sponsor during the previous year in performing its administrative duties, up
to a maximum of $10.00 per year. These duties include the mailing to you of
required periodic reports, dividend statements and tax notices; the arranging
for periodic audits of the Custodian's records by independent certified public
accountants; and the preparation and filing of federal and state reports
essential to the continuance of the Custodianship. This amount is payable from
income dividends and capital gains distributions, but if these dividends and
distributions are insufficient, the amount is collectible by the Custodian from
the proceeds of the sale of Class I Shares held for your account. The amount of
the service charge will be determined annually by pro-rating the Plans'
administrative costs over the total number of Plan accounts. The service charge
on Plans established prior to June 1, 1983 will be as specified in the Plan
Certificate.
    
 
   
     The aggregate annual charges and deductions for maintenance and other
expenses assessed to planholders for the fiscal years ended October 31, 1998,
1997 and 1996, stated as a percentage of total distributions (includes dividends
and capital gains) from Class I Shares for such period or years were 0.34%,
0.40% and 0.61%, respectively. Distributions, if any, are normally declared in
December of each year. The aggregate annual charges and deductions for
maintenance and other expenses assessed to planholders for the fiscal year of
the Sponsor ended December 31, 1998 was $540,345.
    
 
INCIDENTAL SERVICE FEES
 
   
     In addition to the amount of any applicable transfer taxes, a custodian
charge of $2.50 is made in the case of each transfer of title, each change in
your Plan's denomination, each partial or complete liquidation, each
restoration, each declaration of trust (other than one filed concurrently with
the application for your Plan), each recording of an assignment, each reissuance
of your Plan, and each termination of your Plan prior to completion. A charge of
$1.00 is made for each payment under a Systematic Withdrawal Program, and a
charge of $3.00 per account per year is made for the preparation of a complete
transcript of your account. A charge of $5.00 is made for any check or
pre-authorized check which is not honored by the bank on which it is drawn. The
incidental service fees described above will be paid by the Sponsor. Although it
has no current intention of doing so, the Sponsor may reimpose these fees at
some future date.
    
 
   
     Except as specifically provided in this Prospectus, there will be no
deductions, charges, or fees of any kind on Plan payments, Class I Shares held
for your account, or dividends or distributions paid by the Fund.
    
 
                                     TAXES
 
   
     Under the Internal Revenue Code of 1986, as amended (the "Code"), you are
deemed for federal income tax purposes to be the owner of the underlying Class I
Shares accumulated in your account. Dividends and distributions on such shares
paid to you used to pay the Custodian fee or service charge or reinvested in
additional Class I Shares are taxable to you. See "Taxes" in the accompanying
Fund prospectus for a discussion of the tax treatment of such dividends and
    
                                       18
<PAGE>   21
 
   
distributions. As soon as practicable after the close of each calendar year, you
will be advised of the amount and nature of the ordinary income dividends and
capital gains distributions received on your behalf during such year.
    
 
   
     The Creation and Sales Charges deducted from your investments in your Plan
are not deductible for tax purposes by you, but are included in your tax basis
for the Class I Shares in your account. Any Custodian fee and service charge you
may have paid (whether as a deduction from your investments in your Plan or as a
deduction from the distributions made on the Class I Shares in your account) are
deductible for tax purposes by you only if you itemize deductions and then only
to the extent that the Custodian fee and service charge, together with your
other miscellaneous itemized deductions, exceed 2% of your adjusted gross
income. Further, some of your itemized deductions (including any portion of
miscellaneous itemized deductions which exceeds the 2% floor, state and local
income and property taxes, home mortgage interest, and charitable contributions)
will be reduced (but not by more than 80% thereof) by 3% of your adjusted gross
income in excess of $126,600 ($63,300 if you are married and file separately;
for tax years beginning in 1999 and as annually adjusted for inflation). This
amount is calculated differently for married persons filing separate income tax
returns.
    
 
   
     Under provisions of the Code, the Custodian may be required to withhold
from dividends and liquidations 31% of all amounts otherwise payable to you if
you have not provided the Custodian with a correct certified social security
number or tax identification number or if you have been notified by the Internal
Revenue Service that you are subject to "backup withholding" because of
underreporting of reportable payments. The amounts withheld will be credited
against your federal income tax liability, and, if withholding results in an
overpayment of taxes, you may obtain a refund from the Internal Revenue Service.
    
 
   
     Neither the Custodian, BFDS, nor the Sponsor bears any taxes arising from
the custody of the Class I Shares or the operations of the Custodianship under
the Plans. The Custodian, BFDS, and the Sponsor are authorized to incur any
expenses deemed necessary or appropriate in connection with any claim or
possible claim for taxes against the Custodianship or the accounts of
planholders. The Sponsor or the Custodian may, in its discretion, deduct charges
against your account on a pro rata basis (determined by reference to the total
number of Class I Shares affected) in order to pay or set up reserves for such
claims and related expenses.
    
 
                             SUBSTITUTION OF SHARES
 
   
     Shares of the Fund have been the underlying investment for the Plans since
their inception. The Sponsor may substitute shares of another investment medium
as the underlying investment if it deems such action to be in the best interests
of the Planholders. Such substituted investment will be generally comparable in
character and quality to the Class I Shares, and will be registered with the SEC
under the Securities Act of 1933, as amended. Before any substitution can be
made, the Sponsor must:
    
 
          (a) Obtain an order from the SEC approving such substitution under the
     provisions of Section 26(b) of the Investment Company Act of 1940, as
     amended (the "1940 Act");
 
          (b) Give written notice of the proposed substitution to the Custodian;
 
                                       19
<PAGE>   22
 
   
          (c) Give written notice of the proposed substitution to you, giving a
     reasonable description of the substituted fund shares, with the advice
     that, unless you respond within 30 days of the date of mailing of such
     notice, you will be considered to have agreed to bear your pro rata share
     of expenses and taxes in connection with the substitution. The pro rata
     share of expenses and taxes are payable from any income dividends and any
     capital gains distributions, but if such dividends and distributions are
     insufficient, the pro rata share of expenses and taxes are collectable by
     the Custodian from the proceeds of the sale of Fund shares held for your
     account; and
    
 
   
          (d) Provide the Custodian with a signed certificate stating that such
     notice has been given to you.
    
 
   
     If no response is received within the 30-day notice period, the Custodian
will purchase shares of the substituted fund with subsequent investments
received from you and any dividends and distributions which may be reinvested
for your account. If shares of the substituted fund are also to be substituted
for the shares already held, the Sponsor must arrange for the Custodian to be
furnished, without payment of a sales charge of any kind, with shares of the
substituted fund having an aggregate value equal to the value of shares of the
Fund for which they are to be exchanged.
    
 
   
     If Class I Shares are not available for purchase for a period of 90 days or
longer, and the Sponsor fails to substitute other shares, the Custodian may, but
is not required to, select another underlying investment. If the Custodian
selects a substitute investment, it shall first obtain an order from the SEC
approving such substitution as specified above and then shall notify you, and
if, within 30 days after mailing such notice, you give your written approval of
the substitution and agree to bear your pro rata share of actual expenses,
including any tax liability sustained by the Custodian, the Custodian may
thereafter purchase such substituted shares. Your failure to give such written
approval within the 30-day period shall give the Custodian authority to
terminate your Plan.
    
 
   
     If Class I Shares are not available for purchase for a period of 90 days or
longer, and neither the Sponsor nor the Custodian substitutes other shares, the
Custodian has the authority, without further action on its part, to terminate
the Plans.
    
 
                             TERMINATION OF A PLAN
 
   
     A Plan will normally remain in existence until you have made 300 investment
units into your Plan. Neither the Sponsor nor the Custodian can terminate a Plan
established after May 1, 1993 sooner unless you have failed to make investments
under your Plan for a period of 6 consecutive months (12 consecutive months for
Plans established prior to May 1, 1993) from the scheduled due date of the last
investment made (including any investments made in advance of their scheduled
due dates). For example, if your Plan was established after May 1, 1993 and you
have made all investments due under your Plan through June 30th of a given year
(regardless of when such investments were made) and you make no further
investments, your Plan may not be terminated before December 31st of that same
year. Any scheduled investment made prior to the termination of a Plan extends
the due dates of all future investments for a period equal to the period during
which no investments were made. Accordingly, you need only make one investment
during each
6-month period (or 12-month period for Plans established prior to May 1, 1993)
to prevent your Plan from being terminated.
    
 
                                       20
<PAGE>   23
 
   
     A Plan may also be terminated prior to the accumulation of 300 investment
units if shares of the Fund are not available and a substitution is not made.
After 300 investment units have been made, or on the happening of any of the
other events justifying termination, the Sponsor or the Custodian may terminate
a Plan 60 days after mailing to you a written notice of the termination.
    
 
   
     On termination, the Custodian, acting as your agent, must withdraw the
shares from the Custodianship and, as your agent, may surrender for liquidation
all of the Class I Shares credited to your account, or sufficient Class I Shares
to pay all authorized deductions and leave no fractional shares. Any adjustment
in Creation and Sales Charges or other charges occasioned by virtue of your
termination through the exercise of one of the refund privileges will be made at
the same time. The shares and/or cash, after payment of all authorized
deductions, will be held by the Custodian as your agent for delivery to you upon
your instruction. No interest will be paid on any cash balances held. If the
Custodian does not receive a response within 60 days after mailing the notice of
termination to you, the Custodian, in its discretion, may mail the shares, and
its check payable to you, to your last known address of record, and you will be
deemed to have no further rights under your Plan. In all events, terminated
Plans will not be resold. Undeliverable shares and funds will be held by the
Custodian in trust for your account, subject to the abandoned property laws of
The Commonwealth of Massachusetts.
    
 
                                 THE CUSTODIAN
 
   
     State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02101, acts as Custodian for the Plans pursuant to a custodian
agreement, dated September 24, 1982, as amended and restated on June 1, 1983, as
amended and restated on May 1, 1996 (the "Custodian Agreement") with respect to
Plans issued on or after such date. The Custodian is a corporation organized
under the laws of the Commonwealth of Massachusetts. The Custodian's Internal
Revenue Service Employer Identification Number is 04-1867445. The Custodian also
acts as custodian and transfer agent for the Fund.
    
 
   
     The duties of the Custodian under the Custodian Agreement include the
receipt of all of your investments and income dividends and capital gain
distributions on Class I Shares, the processing of all authorized deductions
therefrom and the purchase and retention of Class I Shares for your accounts.
The Custodian also effects partial or complete liquidations of Plans in
connection with withdrawals or terminations and the various other functions
heretofore discussed.
    
 
   
     The Custodian receives and holds in trust without interest all cash and
Class I Shares held by a Plan until completion and/or termination of the Plan.
BFDS keeps a complete record of your account and mails receipts for each of your
investments showing the number of shares held for your account, notices
(including distribution notices and tax statements), reports to shareholders,
prospectuses and proxy material. The Custodian causes periodic audits to be
taken of the records it maintains relating to the Plans, unless such audits are
arranged for by the Sponsor, and prepares and files tax returns and other
reports required by law. The Custodian assumes only those responsibilities
specifically imposed on it under its Custodian Agreement with the Sponsor. The
Custodian has no responsibility for the choice of the underlying investment, for
the investment policies and practices of the management of the Fund, for the
acts or omissions of the Sponsor, for compliance by the Sponsor with the laws of
the United States, any state, or other jurisdiction relating to the sale,
registration or qualification of securities, or for the Sponsors compliance with
any rules, regulations or orders of any regulatory agencies or commissions, for
the validity of written
    
 
                                       21
<PAGE>   24
 
   
designations of beneficiaries executed by planholders, or for signatures
guaranteed by persons other than banks or members of national securities
exchanges.
    
 
   
     The Custodian is authorized to commingle only those payments, dividends and
certificates of Class I Shares which are held for or received from the various
planholders of Plans which are subject to this Prospectus. The Custodian is also
authorized to cause all Plan certificates issued prior to March 1, 1995 to be
registered in its name or in the name of its nominees. While the Custodian does
not assert a lien in general terms on the property held by it, the authorization
conferred on the Custodian to make the various deductions discussed above, and
in certain cases to sell Class I Shares, may be considered authorization to the
Custodian to create such liens.
    
 
   
     The Custodian Agreement cannot be amended to affect your rights and
privileges without your written consent.
    
 
   
     An unlimited number of Plans may be issued under the Custodian Agreement.
    
 
   
     Under certain circumstances as provided in the Custodian Agreement, the
Sponsor or the Custodian has the right to terminate the services of the
Custodian. However, no such termination or resignation may be made as to the
Plans then in force unless all Class I Shares have been liquidated and the
proceeds distributed to you, or unless a successor custodian has been designated
and has accepted the custodianship. Any successor custodian must be a bank or
trust company having at all times aggregate capital, surplus and undivided
profits in excess of $1,000,000. Notice of such a change will be sent to you,
but your consent is not required.

                                    GENERAL
 
   
     The Plans are organized under and are governed by the laws of The
Commonwealth of Massachusetts, except that the laws of the State of New York
govern your substantive legal rights if your Plan was issued prior to June 1,
1983. The Plans are considered to be a unit investment trust under the 1940 Act
and are so registered with the SEC. Such registration does not imply supervision
of management or investment practices or policies by the SEC.
    
 
   
     The Custodian Agreement provides that no adverse changes will be made in
the terms or conditions of Plans once they have been issued. Your consent to
changes in Plans that are not adverse or that apply only to Plans issued after
your Plan was issued is not required. The Sponsor will give you notice of any
changes in any indenture or agreement relating to the Plans and affecting them
or in the identity of the Sponsor or Custodian, but such changes do not require
your consent.

     The Plans are distributed by authorized investment brokers and mutual fund
dealers who are members of the National Association of Securities Dealers, Inc.,
and who have executed dealer agreements with the Sponsor. Commissions of up to
93% of the total Creation and Sales Charges will be paid to such authorized
investment brokers and mutual fund dealers. These dealers and investment brokers
are independent contractors. Nothing herein or in other literature and
confirmations issued by the Sponsor or the Custodian, including the words
"representative" or "commission," shall constitute any dealer or investment
broker, a partner, employee or agent of the Sponsor or the Custodian. Neither
the Sponsor nor the Custodian shall be liable for any acts or obligations of any
such dealer or investment broker. Dealers who receive 90% or more of the
Creation and Sales Charges applicable to Plan payments may be deemed to be
underwriters under the Securities Act of 1933 and may, therefore, be subject to
certain liabilities imposed upon underwriters by such Act. In the event the
broker or dealer of record designated for a Plan is changed after the
establishment of the Plan, such change will appear on the Sponsor's records;
however, payment of commissions on your future investments will continue to be
made to the original broker or dealer of record notwithstanding such change.
    
 
   
     AIM Summit Investors Plans I are presently offered in all states.
    
 
   
     This Prospectus omits some of the information contained in the registration
statement filed with the SEC. You may obtain copies of the registration
statement, including items omitted herein, from the SEC by paying the charges
prescribed under its rules and regulations.

                   ILLUSTRATION OF A HYPOTHETICAL $50 MONTHLY
   
                          AIM SUMMIT INVESTORS PLANS I
    
   
           FOR INVESTMENT IN CLASS I SHARES OF AIM SUMMIT FUND, INC.
    
 
   
     This table shows results of an assumed investment of $50 per month (the
minimum monthly investment Plan) for the period from the beginning of AIM Summit
Investors Plans I, November 1, 1982, to December 31, 1998. The results assume
the reinvestment of capital gains distributions and income dividends in
additional Class I Shares of AIM Summit Fund, Inc.
    
 
   
     You should not consider the results shown in this table as a representation
of the dividend income or capital gain or loss in a Plan today. A Plan cannot
assure a profit or protect against depreciation in declining markets. Common
stock prices fluctuate widely over time.

NOTES:
 
   
  (a)  The fiscal year end of AIM Summit Investors Plans I and the Fund for each
       year after 1992 was changed from December 31 to October 31. All data
       reflect calendar years ended December 31.
    
 
  (b)  Reflects the total amount of monthly investments plus the cumulative
       amount of income dividends reinvested.
 
  (c)  The total deductions for the first 12 months of the hypothetical Plan
       equal $318.00 or 53% of total investments. If all of the investments of a
       15-year Plan were made monthly, total deductions would be $1,035.36 or
       11.5% of the total investment.
 
   
  (d)  Does not include a service charge, not to exceed $10 per year, payable
       first from dividends and distributions and then, if necessary, from
       principal, to cover certain administrative expenses actually incurred.
       The amount of such charge will be determined annually by pro-rating the
       Plans' administrative costs over the total number of Plan accounts. The
       service charge on Plans established prior to June 1, 1983 shall be as
       specified in the Plan Certificate.
    
 
  (e)  Assumes that monthly investments were made on the first business day of
       each month.
 
  (f)  Based on the Fund's year-end net asset value.
 
     No adjustments have been made for any income taxes payable by investors on
reinvested capital gains distributions and reinvested dividends.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors of
A I M Distributors, Inc. and Planholders
of Summit Investors Plans:
 
   
We have audited the accompanying statement of assets and liabilities of Summit
Investors Plans as of October 31, 1998, the related statement of operations for
the year then ended and the statement of changes in net assets for each of the
years in the three-year period then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
    
 
   
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities held as trust property as of October 31, 1998 by
correspondence with the custodian. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
    
 
   
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Summit Investors Plans as of
October 31, 1998, the results of its operations for the year then ended, and the
changes in its net assets for each of the years in the three-year period then
ended in conformity with generally accepted accounting principles.

We have audited the accompanying statement of financial condition of A I M

financial statements based on our audit.
    
 
   
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
    
 
   
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of A I M Distributors, Inc., as of
December 31, 1998, and the results of its operations and its cash flows for the
year then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                               DECEMBER 31, 1998
    
 
   
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
    
 
   
Basis of Presentation
    
 
   
A I M Distributors, Inc. (the Company), is a wholly owned subsidiary of A I M
Advisors, Inc. The Company acts as the principal underwriter and distributor for
affiliated registered investment companies.
    
 
   
Cash Equivalents
    
 
   
The Company considers all highly liquid assets such as cash in banks and amounts
in affiliated money market funds to be cash equivalents.
    
 
   
Securities Transactions
    
 
   
Securities transactions are recorded on a settlement date basis which is
normally the third business day following the trade date (settlement date basis
as compared to trade date basis has no material effect on the Company's
financial position or results of operations). The Company accounts for its
investments at fair market value.
    
 
   
Concentration of Credit Risk
    
 
   
The Company is engaged in brokerage activities in which counterparties primarily
include broker-dealers. In the event that counterparties do not fulfill their
obligations, the Company may be exposed to risk. The risk of default depends on
the creditworthiness of the counterparty. It is the Company's policy to review,
as necessary, the credit standing of each counterparty.
    
 
   
Segregated Trust Account
    
 
   
The segregated trust account represents a U.S. Government agency discount note
on deposit in a segregated trust account as required by the Investment Company
Act of 1940. Such amount is determined in accordance with the requirements of
the Investment Company Act of 1940 to provide cash reserves for refunds that may
be required if investors in a unit investment trust exercise their right to
surrender or withdraw. This note is recorded at fair market value (which
approximates amortized cost) at December 31, 1998.
    
 
   
Underwriting Income
    
 
   
Underwriting income represents sales charges on sales of capital stock of
affiliated registered investment companies, net of commissions and concessions
paid to other dealers.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
Distribution Fees
    
 
   
The Company receives fees from affiliated registered investment companies
pursuant to 12b-1 plans (Investment Company Act of 1940) adopted by the
affiliated registered investment companies. Such fees are paid to the Company as
compensation for expenses incurred by the Company for the distribution of shares
of the affiliated registered investment companies. The fees are based on a
specified annual percentage of a fund's average daily net assets.
    
 
   
Transactions With Affiliated Companies
    
 
   
The Company is allocated expenses by an affiliated company based upon estimates
of time devoted to the operations of the Company by personnel of the affiliated
company and usage of shared facilities. The Company is also allocated revenue
from affiliated companies for services performed in marketing efforts for
affiliated registered investment companies managed by those companies.
    
 
   
The Company has entered into an agreement with its ultimate parent, A I M
Management Group Inc. (Management), whereby Management provides funding to the
Company for payment of Class B share commissions. Management obtains the rights
to certain future revenues to be generated by the Class B shares under the
respective fund's 12b-1 plan provisions and contingent deferred sales charge
(CDSC) provisions for a purchase price equal to a percentage of the price at
which each Class B share is sold. Such transactions occur daily and have been
accounted for as sale transactions. No gain or loss from this arrangement is
reflected in the Company's financial statements since the amount paid by
Management equals the commissions paid by the Company relating to the sale of
Class B shares. Accordingly, amounts received from the respective funds under
the 12b-1 plan provisions and CDSC provisions are not recorded as revenue by the
Company as Management owns the rights to such fees.
    
 
   
Federal Income Taxes
    
 
   
For federal income tax purposes, the Company's income is included in the
consolidated income tax return filed by A I M Management Group Inc., the parent
company of A I M Advisors, Inc. Deferred and current taxes are provided at the
statutory rate in effect during the year (35 percent) by the members of the
consolidated group based on the amount that the respective member would pay or
have refunded if it were to file a separate return. The effective tax rate was
37.4 percent due to the effect of state taxes.
    
 
   
Use of Estimates
    
 
   
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

2. NET CAPITAL REQUIREMENTS:
    
 
   
In accordance with regulations of the Securities and Exchange Commission, the
Company must maintain minimum net capital, as defined, and a ratio of aggregate
indebtedness to net capital that does not exceed 15 to 1, as defined. At
December 31, 1998, the Company had net capital of $5,681,514, which exceeded
required net capital of $284,396 by $5,397,118. The ratio of aggregate
indebtedness to net capital was 1.09 to 1 at December 31, 1998.
    
 
   
3. SUBORDINATED DEBT:
    
 
   
The Company had no subordinated debt at December 31, 1998 or at any time during
the year then ended.

                             DISTRIBUTION AGREEMENT


                  Amendment No. 1 , made this 1st day of March 1999 by and
between AIM SUMMIT FUND, INC., a Maryland corporation (the "Company") and A I M
DISTRIBUTORS, INC., a Delaware corporation (the "Distributor") to that certain
agreement made as of the 28th day of February, 1997 (the "Distribution

                  WHEREAS, the Company and the Distributor have entered into the
Distribution Agreement; and

                  WHEREAS, the Company has divided its common stock into two
classes named Class I Shares and Class II Shares; and

                  WHEREAS, the parties desire to clarify that the Distributor
will act as the principal distributor of both Class I Shares and Class II Shares
of Common Stock; and

                  WHEREAS, the Distributor is to be compensated by the Company
for distribution efforts relating to Class II Shares.

                  NOW, THEREFORE, in consideration of the premises and of other
good and valuable consideration by each of the parties hereto to the other party
paid and of the agreements, covenants and obligations herein contained and
intending to be legally bound, the parties hereto agree as follows:

1.                Except as set forth below, the terms "Company shares," "its

                  in the Distribution Agreement shall mean Class I Shares and
                  Class II Shares of the Company.

2.                Section 1(b) provides that the Distribution Agreement may be
                  continued by the affirmative vote of a specified percentage of
                  the holders of the Company's shares. Section 11 provides that
                  the Distribution Agreement may be terminated by the vote of a
                  majority of the outstanding voting securities of the Company.
                  In order to make it clear that the Distribution Agreement may
                  be continued or terminated, as the case may be, on a class
                  basis, all references to the Company's shares or to the
                  outstanding voting securities of the Company in paragraph 1(b)
                  and paragraph 11 of the Distribution Agreement shall mean
                  Class I Shares or Class II Shares of the Company, as the case
                  may be.

3.                A new paragraph 12 shall be added which reads in its entirety
                  as follows:

                  12.      Subject to the limitations, if any, of applicable law
                           including the applicable National Association of
                           Securities Dealers, Inc. ("NASD") Conduct Rules
                           (formerly, the NASD Rules of Fair Practice) regarding
                           asset-based sales charges, the Company shall pay to
                           the Distributor as a reimbursement for all or a
                           portion of such expenses, or as


<PAGE>   2


                           reasonable compensation for distribution of the Class
                           II Shares, an asset-based sales charge in an amount
                           equal to 0.05% per annum of the average daily net
                           asset value of the Class II Shares from time to time
                           (the "Distributor's 12b-1 Share"), such sales charge
                           to be payable pursuant to the distribution plan
                           adopted pursuant to Rule 12b-1 under the Investment
                           Company Act of 1940 Act (the "Plan"). The

                           paid to the Distributor as soon as practicable after
                           the end of each such calendar month (unless the
                           Distributor shall specify a later date in written
                           instructions to the Company). The Distributor shall
                           maintain adequate books and records to permit
                           calculations periodically (but not less than monthly)
                           of, and shall calculate on a monthly basis, the

WITHHOLDING INFORMATION (Substitute Form W-9)
Under the Interest and Dividend Tax Compliance Act of 1983, we are required to
have the following certification: Under the penalties of perjury, I certify
that:
     (1)  The number shown above is my correct Taxpayer Identification Number
          (or I am waiting for a number to be issued to me), AND
     (2)  I am not subject to backup withholding because (a) I am exempt from
          backup withholding, or (b) I have not been notified by the Internal
          Revenue Service that I am subject to backup withholding as a result of
          a failure to report all interest or dividends, or (c) the IRS has
          notified me that I am no longer subject to backup withholding.
You must cross out item 2 above if you have been notified by the IRS that you

apply. For mortgage interest paid, the acquisition or abandonment of secured
property, contributions to an individual retirement arrangement (IRA), and

Section references are to the Internal Revenue Code.

PURPOSE OF FORM. -- A person who is required to file an information return with
the IRS must get your correct TIN to report income paid to you, real estate
transactions, mortgage interest you paid, the acquisition or abandonment of
secured property, cancellation of debt or contributions you made to an IRA. Use
Form W-9 to give your correct TIN to the requester (the person requesting your
TIN) and when applicable, (1) to certify the TIN you are giving is correct (or
you are waiting for a number to be issued), (2) to certify you are not subject
to backup withholding, or (3) to claim exemption from backup withholding if you
are an exempt payee. Giving your correct TIN and making the appropriate
certifications will prevent certain payments from being subject to backup
withholding.

Note: If a requester gives you a form other than a W-9 to request your TIN, you
must use the requester's form if it is substantially similar to this Form W-9.

WHAT IS BACKUP WITHHOLDING? - Persons making certain payments to you must
withhold and pay to the IRS 31% of such payments under certain conditions. This
is called "backup withholding." Payments that could be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.

If you give the requester the correct TIN, make the proper certifications, and
report all your taxable interest and dividends on your tax return, your payments
will not be subject to backup withholding. Payments you receive will be subject
to backup withholding if:

     1. You do not furnish your TIN to the requester, or

     2. The IRS tells the requester that you furnished an incorrect TIN, or

     3. The IRS tells you that you are subject to backup withholding because you
did not report all your interest and dividends on your tax return (for
reportable interest and dividends only), or

     4. You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened
after 1983 only), or

     5. You do not certify your TIN. See the Part III instructions for
exceptions.

     Certain payees and payments are exempt from backup withholding and
information reporting. See the Part II instructions and the separate
instructions for the Requester of Form W-9.

HOW TO GET A TIN. -- If you do not have a TIN, apply for one immediately. To
apply, get FORM SS-5, Application for a Social Security Number Card (for
individuals), from your local office of the Social Security Administration, or
FORM SS-4, Application for Employer Identification Number (for business and all
other entities), from your local IRS office.

     If you do not have a TIN, write "Applied For" in the space for the TIN in
Part I, sign and date the form, and give it to the requester. Generally, you
will then have 60 days to get a TIN and give it to the requester. If the
requester does not receive your TIN within 60 days, backup withholding, if
applicable, will begin and continue until you furnish your TIN.

NOTE: Writing "Applied For" on the form means that you have already applied for
a TIN or that you intend to apply for one soon.

As soon as you receive your TIN, complete another Form W-9, include your TIN,
sign and date the form, and give it to the requester.

PENALTIES

FAILURE TO FURNISH TIN. -- If you fail to furnish your correct TIN to a
requester, you are subject to a penalty of $50 for each such failure unless your
failure is due to reasonable cause and not to willful neglect.

CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you make
a false statement with no reasonable basis that results in no backup
withholding, you are subject to $500 penalty.

CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

MISUSE OF TINs. -- If the requesters discloses or uses TINs in violation of
Federal law, the requester may be subject to civil and criminal penalties.

SPECIFIC INSTRUCTIONS

NAME. -- If you are individual, you must generally enter the name shown on your
social security card. However, if you have changed your last name, for instance,
due to marriage, without informing the Social Security Administration of the
name change, please enter your first name, the last name shown on your social
security card, and your new last name.

SOLE PROPRIETOR. -- You must enter your individual name. (Enter either your SSN
or EIN in Part 1.) You may enter your business name or "doing business as" name
on the business name line. Enter your name as shown on your social security card
and business name as it was used to apply for your EIN on Form SS-4.

PART I -- TAXPAYER IDENTIFICATION NUMBER (TIN)

You must enter your TIN in the appropriate box. If you are a sole proprietor,
you may enter your SSN or EIN. Also see the chart on this page for further
clarification of name and TIN combinations. If you do not have a TIN, follow the
instructions under How to Get a TIN on page 1.

PART II -- FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING

Individuals (including sole proprietors) are not exempt from backup withholding.
Corporations are exempt from backup withholding for certain payments, such as
interest and dividends. For a complete list of exempt payees, see the separate
instructions for the Requester of Form W-9.

If you are exempt from backup withholding, you should still complete this form
to avoid possible erroneous backup withholding. Enter your correct TIN in Part
I, write "Exempt" in Part II, and sign and date the form. If you are a
nonresident alien or a foreign entity not subject to backup withholding, give
the requester a completed Form W-8, Certificate of Foreign Status.

PART III -- CERTIFICATION

For a joint account, only the person whose TIN is shown in Part I should sign.

     1. INTEREST, DIVIDEND, AND BARTER EXCHANGE ACCOUNTS OPENED BEFORE 1984 AND
BROKER ACCOUNTS CONSIDERED ACTIVE DURING 1983. You must give your correct TIN,
but you do not have to sign the certification.

     2. INTEREST, DIVIDEND, BROKER, AND BARTER EXCHANGE ACCOUNTS OPENED AFTER
1983 AND BROKER ACCOUNTS CONSIDERED INACTIVE DURING 1983. You must sign the
certification or backup withholding will apply. If you are subject to backup
withholding and you are merely providing your correct TIN to the requester, you
must cross out item 2 in the certification before signing the form.

     3. REAL ESTATE TRANSACTIONS. You must sign the certification. You may cross
out item 2 of the certification.

     4. OTHER PAYMENTS. You must give your correct TIN, but you do not have to
sign the certification unless you have been notified of an incorrect TIN. Other
payments include payments made in the course of the requester's payments made in
the course of the requester's trade or business for rents, royalties, goods
(other than bills for merchandise), medical and health care services, payments
to a nonemployee for services (including attorney and accounting fees), and
payments to certain fishing boat crew members.

     5. MORTGAGE INTEREST PAID BY YOU, ACQUISITION OR ABANDONMENT OF SECURED
PROPERTY, CANCELLATION OF DEBT, OR IRA CONTRIBUTIONS. You must give your correct
TIN, but you do not have to sign the certification.

PRIVACY ACT NOTICE

Section 6109 requires you to give your correct TIN to persons who must file
information returns with the IRS to report interest, dividends, and certain
other income paid to you, mortgage interest you paid, the acquisition or
abandonment of secured property, cancellation of debt, or contributions you made
to an IRA. The IRS uses the numbers for identification purposes and to help
verify the accuracy of your tax return. You must provide your TIN whether or not
you are required to file a tax return. Payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
give a TIN to a payer. Certain penalties may also apply.
