                      SEMIANNUAL REPORT / CHAIRMAN'S LETTER



                    Dear Fellow Shareholder:

                    With only several months remaining in 1999, the question on
    [PHOTO OF       many of your minds may be, "How will the year 2000 computer
   Charles T.       issue affect AIM and my investments?" We would like you to
     Bauer,         feel comfortable.
  Chairman of           During March and April, AIM participated in an
  the Board of      industrywide test that gave us a chance to see how our
    THE FUND        technology systems might be affected by the changeover to
  APPEARS HERE]     the year 2000 (Y2K). Everything went as well as we had
                    hoped; in general, the industry sailed through the testing
                    process with flying colors. The financial industry has been
                    seen as a leader in planning for year 2000 concerns. Thus,
                    it was no surprise to most participants that the test was an
                    overwhelming success.
                        The general purpose of the process was to test
                    electronic interfaces among financial industry members in
                    the United States and to follow transactions through a
typical trading cycle--from order entry to the settlement process. Investment
banks, broker-dealers, custodian banks and mutual fund companies all worked
together to make this possible. Approximately 400 firms were involved in the
testing; AIM was one of 70 asset managers.

TEST RESULTS EXCELLENT
During the testing process, thousands of transactions were submitted and
approximately 260,000 steps were tested. Of those, only a handful experienced
minor glitches--just 0.02% of the total number of transactions. All problems
were worked through quickly before the hypothetical trades were settled. Of
course, AIM will keep testing and planning throughout 1999 as a precaution.

AIM'S INTERNAL EFFORTS CONTINUE
As you know from our previous communications to you, AIM has been addressing the
year 2000 issue for several years. During 1998, we made substantial progress on
our preparations. We are now in the final phases of the project, continually
testing internal applications and our interfaces with outside parties. On the
investment side, our portfolio management staff is evaluating the Y2K
preparedness of the companies in which we invest.
    We feel that our preparations for 2000 are very comprehensive, and the
industrywide testing showed that our colleagues in the financial industry are
also working hard to be ready for the new year. We do not think shareholders
need to take any extraordinary measures with their investments to prepare for
2000. However, if you have any lingering concerns, it may reassure you to know
that AIM is finalizing contingency plans that will be ready if there are
unexpected problems. Our plans will give AIM employees guidelines to follow for
a wide variety of situations.
    For a more comprehensive discussion of our Y2K efforts and for periodic
updates, please visit our Web site, www.aimfunds.com.
    We are pleased to send you this report covering your fund's performance
during the six months ended April 30, 1999. If you have any questions or
comments, please contact our Client Services department at 800-659-1005.

Sincerely,

/s/ CHARLES T. BAUER

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW


AIM CHARTER FUND BEATS S&P 500

THE STOCK MARKET SEEMS TO HAVE DONE VERY WELL OVER THE PAST SIX MONTHS. HOW DID
THE AIM CHARTER FUND PERFORM?
The fund's Institutional Class shares turned in an outstanding performance for
the period ending April 30, 1999. The fund gained 27.89%, beating the
performance of the S&P 500, which reported a 22.31% return. It also outperformed
its peer group represented by the Lipper Growth & Income Funds Index, which
gained 17.85%. Net assets climbed from $43.8 million to $59 million over the
six-month reporting period.

WHAT WERE MARKET CONDITIONS LIKE OVER THE REPORTING PERIOD?
In late 1998, the Federal Reserve Board lowered interest rates and spurred a
market rally. That rally continued through 1999, but not all stocks
participated. The Dow Jones Industrial Average crossed the 10,000 threshold
during the reporting period, but its performance reflected the strength of a
small number of major American corporations. The rest of the market did not
perform as well as leading large-company stocks. In April, the market broadened
as earnings improved across a wider spectrum of companies.

================================================================================
GROWTH OF NET ASSETS
- --------------------------------------------------------------------------------
10/31/98             $43.8 million

4/30/99              $59 million
================================================================================

WHAT CONTRIBUTED TO THE STRONG PERFORMANCE OF THE FUND?
The fund invests in large, brand-name companies in a market where size matters.
These big companies have large research and development budgets to develop new
products, economies of scale to reduce costs, and access to global markets to
sell products. In response to the narrowness of the market over the past six
months, we reduced the number of holdings in the fund from 145 to 94.

WHAT WERE THE TOP SECTORS FOR THE FUND?
Our main sectors are technology, health care and financial stocks, where
companies continue to show strong earnings growth. Technology now makes up 27.9%
of the portfolio, up from 21% at the end of the fiscal year.

WHY IS TYCO YOUR LARGEST HOLDING?
We like Tyco because it is a diversified corporation with leading positions in a
wide array of businesses. The company has four divisions, and each exhibits
strength and stability -- health-care products, fire and security systems,
flow-control technology (pipes, pipe fittings and tubing) and electrical
components. Some of the products made by its subsidiaries include Curity
bandages, fire extinguishers, and undersea fiber-optic cable.
    The Bermuda-based company has grown through acquisitions, buying nearly 100
companies and growing its earnings 26% over the past six years. Its most recent
acquisitions include an $11 billion purchase of AMP, an electronics equipment
maker, and a $3.27 billion deal for Raychem, a telecommunications cable company.
    Tyco embodies much of what we look for in a growth stock: leading
market-share positions in leading growth industries both in the United States
and in international markets, which recently have begun to show signs of
improving growth prospects.

DOES THE FUND OWN ANY INTERNET STOCKS?
Yes. The leading Internet holding for AIM Charter Fund is America Online. The
No. 1 online Internet service provider has about 17 million subscribers
worldwide and recently announced quarterly earnings that beat Wall Street
estimates. The company successfully closed its $10.2 billion acquisition of
Netscape, a major Internet browser system.
    The fund also participated in a large convertible bond offering for
Amazon.com, an online bookseller. Although Amazon.com has yet to make a profit,
the company's revenue has risen 236% in the most recent quarter. Amazon.com has
expanded its niche to offer music, videos, gifts and auctions online.
    Many of the fund's Internet investments aren't involved with online access
or e-commerce. A major Internet player is MCI WorldCom, the world's
second-largest long-distance company. In its most recent quarterly report, MCI
WorldCom's sales from its Internet business jumped 60%, while its voice lines
grew by 7%.
    Another of our core holdings, Microsoft, is a key Internet player. In a deal
announced shortly after the close of the reporting period, Microsoft is
investing $5 billion for a small stake in AT&T. With its set-top boxes, AT&T
will offer digital

cable services using the Microsoft Windows operating system. Microsoft has cut
other deals to steer telecommunications business its way. As cable and phone
companies build networks to provide voice, video and data over the same
pipeline, Microsoft hopes to attract more users for its multimedia
communications software.

WHAT TYPE OF HEALTH-CARE COMPANIES DO YOU FAVOR?
The fund's health-care holdings make up about 14% of the portfolio and are split
between diversified health-care companies such as Bristol-Myers Squibb and major
pharmaceuticals such as Pfizer. Our investment in this sector has been driven by
long-term demographic trends. The population is aging and requires more health
care. Worldwide drug sales are rising at a rate of 8% to 10% a year.
    We're seeing a continuation of the "size matters" theme with major drug
companies. Bringing a new drug to market can cost about $1 billion, so major
pharmaceuticals such as Pfizer have a clear advantage over their smaller
competitors.

WHAT'S YOUR OUTLOOK FOR THE NEXT SIX MONTHS?
Strong economic growth in the United States continues to buoy the stock market.
The main question is interest rates. Inflation rose unexpectedly in April,
prompting the Fed to shift to a bias of raising interest rates at its May
meeting. If the Fed actually does tighten monetary policy, it could have a
negative effect on stock performance.
    We believe earnings will continue to drive the market. The fund's investment
discipline can benefit shareholders in this type of environment, and we're
confident that the fund is well-positioned to continue its strong performance.

NOTES TO FINANCIAL STATEMENTS

APRIL 30, 1999
(UNAUDITED)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Charter Fund (the "Fund") is a series portfolio of AIM Equity Funds, Inc.
(the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of nine separate portfolios. The
Fund currently offers four different classes of shares: Class A shares, Class B
shares, Class C shares and the Institutional Class. Class A shares are sold with
a front-end sales charge. Class B shares and Class C shares are sold with a
contingent deferred sales charge. Matters affecting each portfolio or class will
be voted on exclusively by the shareholders of such portfolio or class. The
assets, liabilities and operations of each portfolio are accounted for
separately. Information presented in these financial statements pertains only to
the Fund. The Fund's investment objective is to provide growth of capital, with
current income as a secondary objective.
  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 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. The
following is a summary of significant accounting policies followed by the Fund
in the preparation of its financial statements.
A.  Security Valuations-A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price on the exchange where
    the security is principally traded, or lacking any sales on a particular
    day, the security is valued at the closing bid price on that day. Each
    security traded in the over-the-counter market (but not including securities
    reported on the NASDAQ National Market System) is valued at the mean between
    the last bid and asked prices based upon quotes furnished by market makers
    for such securities. Each security reported on the NASDAQ National Market
    System is valued at the last sales price on the valuation date, or absent a
    last sales price, at the closing bid price. Debt obligations (including
    convertible bonds) are valued on the basis of prices provided by an
    independent pricing service. Prices provided by the pricing service may be
    determined without exclusive reliance on quoted prices, and may reflect
    appropriate factors such as yield, type of issue, coupon rate and maturity
    date. Securities for which market prices are not provided by any of the
    above methods are valued at the last bid price based upon quotes furnished
    by independent sources. Securities for which market quotations are not
    readily available or are questionable are valued at fair value as determined
    in good faith by or under the supervision of the Company's officers in a
    manner specifically authorized by the Board of Directors of the Company.
    Short-term obligations having 60 days or less to maturity are valued at
    amortized cost which approximates market value. Generally, trading in
    foreign securities is substantially completed each day at various times
    prior to the close of the New York Stock Exchange. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the New York Stock Exchange.
    Occasionally, events affecting the values of such securities and such
    exchange rates may occur between the times at which they are determined and
    the close of the New York Stock Exchange which will not be reflected in the
    computation of the Fund's net asset value. If events materially affecting
    the value of such securities occur during such period, then these securities
    will be valued at their fair value as determined in good faith by or under
    the supervision of the Board of Directors.
B.  Bond Premiums-It is the policy of the Fund not to amortize market premiums
    on bonds for financial reporting purposes.
C.  Securities Transactions, Investment Income and Distributions-Securities
    transactions are accounted for on a trade date basis. Realized gains or
    losses on sales are computed on the basis of specific identification of the
    securities sold. Interest income is recorded as earned from settlement date
    and is recorded on the accrual basis. Dividend income and distributions to
    shareholders are recorded on the ex-dividend date and are paid annually.
D.  Federal Income Taxes-The Fund intends to comply with the requirements of the
    Internal Revenue Code necessary to qualify as a regulated investment company
    and, as such, will not be subject to federal income taxes on otherwise
    taxable income (including net realized capital gains) which is distributed
    to shareholders. Therefore, no provision for federal income taxes is
    recorded in the financial statements.
E.  Expenses-Distribution and transfer agency expenses directly attributable to
    a class of shares are charged to that class' operations. All other expenses
    are allocated among the classes.
F.  Foreign Currency Translations-Portfolio securities and other assets and
    liabilities denominated in foreign currencies are translated into U.S.
    dollar amounts at date of valuation. Purchases and sales of portfolio
    securities and income items denominated in foreign currencies are translated
    into U.S. dollar amounts on the respective dates of such transactions. The
    Fund does not separately account for that portion of the results of
    operations resulting from changes in foreign exchange rates on investments
    and the fluctuations arising from changes in market prices of securities
    held. Such fluctuations are included with the net realized and unrealized
    gain or loss from investments.
G.  Foreign Currency Contracts-A foreign currency contract is an obligation to
    purchase or sell a specific currency for an agreed upon price at a future
    date. The Fund may enter into a foreign currency contract to attempt to
    minimize the risk to the Fund from adverse changes in the relationship
    between currencies. The Fund may enter into a foreign currency contract for
    the purchase or sale of a security denominated in a foreign currency in
    order to "lock in" the U.S. dollar price of that security. The Fund could be
    exposed to risk if counterparties to the contracts are unable to meet the
    terms of their contracts.

<PAGE>   13

H.  Stock Index Futures Contracts-The Fund may purchase or sell stock index
    futures contracts as a hedge against changes in market conditions. Initial
    margin deposits required upon entering into futures contracts are satisfied
    by the segregation of specific securities as collateral for the account of
    the broker (the Fund's agent in acquiring the futures position). During the
    period the futures contracts are open, changes in the value of the contracts
    are recognized as unrealized gains or losses by "marking to market" on a
    daily basis to reflect the market value of the contracts at the end of each
    day's trading. Variation margin payments are made or received depending upon
    whether unrealized gains or losses are incurred. When the contracts are
    closed, the Fund recognizes a realized gain or loss equal to the difference
    between the proceeds from, or cost of, the closing transaction and the
    Fund's basis in the contract. Risks include the possibility of an illiquid
    market and that a change in the value of the contracts may not correlate
    with changes in the value of the securities being hedged.
I.  Covered Call Options-The fund may write call options, but only on a covered
    basis; that is, the Fund will own the underlying security. Options written
    by the Fund normally will have expiration dates between three and nine
    months from the date written. The exercise price of a call option may be
    below, equal to, or above the current market value of the underlying
    security at the time the option is written. When the Fund writes a covered
    call option, an amount equal to the premium received by the Fund is recorded
    as an asset and an equivalent liability. The amount of the liability is
    subsequently "marked-to-market" to reflect the current market value of the
    option written. The current market value of a written option is the mean
    between the last bid and asked prices on that day. If a written call option
    expires on the stipulated expiration date, or if the Fund enters into a
    closing purchase transaction, the Fund realizes a gain (or a loss if the
    closing purchase transaction exceeds the premium received when the option
    was written) without regard to any unrealized gain or loss on the underlying
    security, and the liability related to such option is extinguished. If a
    written option is exercised, the Fund realizes a gain or a loss from the
    sale of the underlying security and the proceeds of the sale are increased
    by the premium originally received.
      A call option gives the purchaser of such option the right to buy, and the
    writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to acquire the security which is the subject of the
    call option at any time during the option period. During the option period,
    in return for the premium paid by the purchaser of the option, the Fund has
    given up the opportunity for capital appreciation above the exercise price
    should the market price of the underlying security increase, but has
    retained the risk of loss should the price of the underlying security
    decline. During the option period, the Fund may be required at any time to
    deliver the underlying security against payment of the exercise price. This
    obligation is terminated upon the expiration of the option period or at such
    earlier time at which the Fund effects a closing purchase transaction by
    purchasing (at a price which may be higher than that received when the call
    option was written) a call option identical to the one originally written.
J.  Put options-The Fund may purchase put options. By purchasing a put option,
    the Fund obtains the right (but not the obligation) to sell the option's
    underlying instrument at a fixed strike price. In return for this right, a
    Fund pays an option premium. The option's underlying instrument may be a
    security, or a futures contract. Put options may be used by a Fund to hedge
    securities it owns by locking a minimum price at which the Fund can sell. If
    security prices fall, the put option could be exercised to offset all or a
    portion of the Fund's resulting losses. At the same time, because the
    maximum the Fund has at risk is the cost of the option, purchasing put
    options does not eliminate the potential for the Fund to profit from an
    increase in the value of the securities hedged.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Company has entered into a master investment advisory agreement with A I M
Advisors, Inc. ("AIM"). Under the terms of the master investment advisory
agreement, the Fund pays an advisory fee to AIM at the annual rate of 1.0% of
the first $30 million of the Fund's average daily net assets, plus 0.75% of the
Fund's average daily net assets in excess of $30 million to and including $150
million, plus 0.625% of the Fund's average daily net assets in excess of $150
million. AIM has contractually agreed to waive a portion of its advisory fees
paid by the Fund to AIM to the extent necessary to reduce the fees paid by the
Fund at net asset levels higher than those currently incorporated in the present
advisory fee schedule. Under the contractual waiver, AIM will receive a fee
calculated at the annual rate of 1.0% of the first $30 million of the Fund's
average daily net assets, plus 0.75% of the Fund's average daily net assets in
excess of $30 million to and including $150 million, plus 0.625% of the Fund's
average daily net assets in excess of $150 million to and including $2 billion,
plus 0.60% of the Fund's average daily net assets in excess of $2 billion. The
waiver is contractual and may not be terminated without approval of the Board of
Directors. During the six months ended April 30, 1999, AIM waived fees of
$506,799. Under the terms of a master sub-advisory agreement between AIM and
A I M Capital Management, Inc. ("AIM Capital"), AIM pays AIM Capital 50% of the
amount paid by the Fund to AIM.
  The Fund, pursuant to a master administrative services agreement with AIM, has
agreed to reimburse AIM for certain administrative costs incurred in providing
accounting services to the Fund. During the six months ended April 30, 1999, AIM
was reimbursed $92,412 for such services.
  The Fund, pursuant to a transfer agent and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. During the six months ended April 30, 1999,
AFS was paid $2,259,697 with respect to the Class A, Class B, Class C and
Institutional Class shares.
  The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares of the Fund. The Company has adopted
distribution plans pursuant to Rule 12b-1 under the 1940 Act with respect to the
Fund's Class A shares and Class C shares (the "Class A and C Plan"), and the
Fund's Class B shares (the "Class B Plan") (collectively, the "Plans"). The
Fund, pursuant to the Class A and C Plan, pays AIM

                                AIM CHARTER FUND                              11
<PAGE>   14

Distributors compensation at an annual rate of 0.30% of the average daily net
assets of the Class A shares and 1.00% of the average daily net assets of Class
C shares. The Fund, pursuant to the Class B Plan, pays AIM Distributors
compensation at an annual rate of 1.00% of the average daily net assets of the
Class B shares. Of these amounts, the Fund may pay a service fee of 0.25% of the
average daily net assets of Class A, Class B or C shares to selected dealers and
financial institutions who furnish continuing personal shareholder services to
their customers who purchase and own the appropriate class of shares of the
Fund. Any amounts not paid as a service fee under the Plans would constitute an
asset-based sales charge. The Plans also impose a cap on the total sales
charges, including asset-based sales charges that may be paid by the respective
classes. During the six months ended April 30, 1999, the Class A, Class B and
Class C shares paid AIM Distributors $6,378,547, $8,400,680, and $270,044,
respectively, as compensation under the Plans.
  AIM Distributors received commissions of $898,342 from sales of Class A shares
of the Fund during the six months ended April 30, 1999. Such commissions are not
an expense of the Fund. They are deducted from, and are not included in, the
proceeds from sales of Class A shares. During the six months ended April 30,
1999, AIM Distributors received commissions of $54,352 in contingent deferred
sales charges imposed on redemptions of Fund shares. Certain officers and
directors of the Company are officers and directors of AIM, AIM Capital, AIM
Distributors, AFS, and FMC.
  During the six months ended April 30, 1999, the Fund paid legal fees of $5,369
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Company's directors. A member of that firm is a director of the Company.

NOTE 3-INDIRECT EXPENSES

During the six months ended April 30, 1999, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $39,540 and $53,058, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $92,598 during the six months ended April 30, 1999.

NOTE 4-DIRECTORS' FEES

Directors' fees represent remuneration paid or accrued to each director who is
not an "interested person" of AIM. The Company may invest directors' fees, if so
elected by a director, in mutual fund shares in accordance with a deferred
compensation plan.

NOTE 5-BORROWINGS

The Fund is a participant in a committed line of credit facility with a
syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 1999, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.05% on the unused balance of the committed line. The
commitment fee is allocated among the funds based on their respective average
net assets for the period.

NOTE 6-INVESTMENT SECURITIES

The aggregate amount of investment securities (other than short-term securities)
purchased and sold by the Fund during the six months ended April 30, 1999 was

                     SEMIANNUAL REPORT / MANAGERS' OVERVIEW



FUND'S SIX-MONTH RETURNS IMPRESSIVE

HOW DID AIM CONSTELLATION FUND PERFORM DURING THE SIX MONTHS ENDED APRIL 30,
1999?
The fund's Institutional Class produced an impressive 21.47%% cumulative total
return, outpacing the 18.86% total return of the Standard & Poor's MidCap 400
Index during the same period. Net assets under management grew from $189.0
million to $212.2 million during the six-month reporting period.

WHAT WERE MARKETS LIKE DURING THE REPORTING PERIOD?
The six-month period started well, as midsize-company stocks benefited from rate
cuts by the Federal Reserve Board last fall. Historically, midcapitalization
stocks have done well when interest rates are falling.
    Early in 1999, the market environment was not so hospitable to midcap
stocks. The technology sector in particular was badly bruised after turning in a
sterling performance during 1998. Investors began to worry about a bubble
developing, especially in high-flying Internet stocks--the ".com" universe. A
sell-off in the technology area affected the fund because of our significant
holdings in technology industries. But the markets rebounded when first-quarter
1999 earnings reports came in quite strong. For instance, portfolio holding EMC
Corp., a maker of information storage and retrieval systems, reported a 51%
rise in earnings for the first quarter of 1999, its eighth consecutive quarter
of revenue and earnings growth in excess of 30%.

DID THE FUND REMAIN HEAVILY INVESTED IN TECHNOLOGY?
Yes. The tech sector represents more than a third of net assets. Because of our
earnings-driven investment discipline, we did not participate in the huge run-up
in Internet stocks during 1998. Many of these companies simply have no earnings
to report. Our technology holdings tend to be the companies that make the
Internet possible. An example is PMC-Sierra Inc., which develops semiconductor
components for the broadband and high-bandwidth communications network
industries.
    Some holdings that are very Internet and technology related aren't
officially part of the technology sector. A good example is Charles Schwab, the
discount broker that now has a huge presence in on-line trading. The rising
value of Schwab stock made an important contribution to the fund's solid
performance during the period covered by this report.

WERE THERE INDUSTRIES WHERE YOU REDUCED YOUR HOLDINGS?
Health care, which represented about 15% of holdings six months ago, was down to
less than 10% by the close of the reporting period. The stocks of health-care
service providers continue to perform poorly. Medicare reimbursement policy has
eroded hospitals' earnings, and stiff competition is preventing HMOs from
raising client fees.
    Nevertheless, there are opportunities in health care. Our largest holding as
a percent of net assets is Guidant, maker of stents and other devices used in
cardiac care. A company seems to need that kind of market niche to prosper in
health care now.
    This is a sector where negative sentiment is taking down good stocks along
with the bad. Omnicare, for example, dispenses drugs for nursing homes and
provides computerized record keeping and third-party billing for patients in its
clients' facilities. Its stock took a beating early in 1999 despite the fact
that the company has an excellent long-term performance record and saw
double-digit sales and earnings growth during 1998. We kept the stock in our
portfolio despite market pressure on it because we are confident about its
long-term growth potential.

WHERE ELSE DID YOU FIND OPPORTUNITIES?
Certain restaurant stocks have become attractive recently. There was serious
overbuilding in the restaurant industry a few years back, but that seems to have
stopped. Outback Steakhouse saw earnings grow 50% last year. We also own Brinker
International, owner of the Chili's chain; Brinker's strong earnings growth met
our investment criteria.
    A newcomer to our top 10 list is Omnicom Group, which operates advertising
agencies worldwide; for first quarter 1999, both revenue and earnings rose 28%
over first quarter 1998. Another new name

on that list is Providian Financial, which extends credit to marginal customers
by issuing secured credit cards tied to the borrowers' savings accounts with the
company. Providian reported record earnings for the first quarter of 1999,
citing a combination of strong account growth and an improved credit loss rate.

THE DOW JONES INDUSTRIAL AVERAGE CROSSED THE 10,000 MARK DURING THE REPORTING
PERIOD. WHY HAS FUND PERFORMANCE NOT TRACKED THE DOW?
The fund invests mainly in medium-sized companies. The Dow reflects the
performance of just 30 companies, all of them very large, including Exxon,
General Electric, and Coca-Cola, none of which are portfolio holdings. People
see the Dow in five-digit territory and wonder why some of their investments
aren't performing the same way. The Dow was up 18.15% during 1998. Remarkably,
it rose exactly the same percentage, 18.15%, between the opening of 1999 and the
close of the reporting period on April 30. Shortly after the reporting period
closed, it passed the 11,000 mark. Many people don't realize that the strength
of one company, IBM, which is not a portfolio holding, explains a lot of Dow
performance. A fund that specializes in midcap stocks, as AIM Constellation Fund
does, will not behave the way the Dow does.
    The Dow is a great barometer of American big business, but it is of little
use as a benchmark for a mutual fund. Most equity funds are much more
diversified than the Dow.

WHAT IS YOUR OUTLOOK?
Toward the close of the reporting period, markets started to pay more attention
to midcap stocks. During April, the S&P MidCap 400 Index rose 7.88% while the
large-cap S&P 500 rose 3.87%. It's too early to tell if this will be a long-term
change in market sentiment. Of course, we hope it is. We have repeatedly stated
our belief that the time is ripe for a rally in midcap stocks. Midsize companies
have been reporting much better earnings than their large-cap counterparts while
the valuations of midcap stocks remain relatively low.
    We will continue to seek out the best-performing companies in the midcap
sector; the fund should be well positioned for an ongoing rally in midcap
stocks.

NOTES TO FINANCIAL STATEMENTS

April 30, 1999
(Unaudited)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Constellation Fund (the "Fund") is a series portfolio of AIM Equity Funds,
Inc. (the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of nine separate portfolios. The
Fund currently offers four different classes of shares: Class A shares, Class B
shares, Class C shares and the Institutional Class. Class B shares commenced
sales on November 3, 1997. Class A shares are sold with a front-end sales
charge. Class B shares and Class C shares are sold with a contingent deferred
sales charge. Matters affecting each portfolio or class will be voted on
exclusively by the shareholders of such portfolio or class. The assets,
liabilities and operations of each portfolio are accounted for separately.
Information presented in these financial statements pertains only to the Fund.
The Fund's investment objective is to seek capital appreciation.
    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 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. The following is a summary of the significant accounting policies
followed by the Fund in the preparation of its financial statements.
A.  Security Valuations--A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price on the exchange where
    the security is principally traded, or lacking any sales on a particular
    day, the security is valued at the closing bid price on that day. Each
    security traded in the over-the-counter market (but not including securities
    reported on the NASDAQ National Market System) is valued at the mean between
    the last bid and asked prices based upon quotes furnished by market makers
    for such securities. Each security reported on the NASDAQ National Market
    System is valued at the last sales price on the valuation date or absent a
    last sales price, at the closing bid

 24                          AIM CONSTELLATION FUND
<PAGE>   27
    price. Debt obligations (including convertible bonds) are valued on the
    basis of prices provided by an independent pricing service. Prices provided
    by the pricing service may be determined without exclusive reliance on
    quoted prices, and may reflect appropriate factors such as yield, type of
    issue, coupon rate and maturity date. Securities for which market quotations
    are not readily available or are questionable are valued at fair value as
    determined in good faith by or under the supervision of the Company's
    officers in a manner specifically authorized by the Board of Directors of
    the Company. Short-term obligations having 60 days or less to maturity are
    valued at amortized cost which approximates market value. Generally, trading
    in foreign securities is substantially completed each day at various times
    prior to the close of the New York Stock Exchange. The values of such
    securities used in computing the net asset value of the Fund's shares are
    determined as of such times. Foreign currency exchange rates are also
    generally determined prior to the close of the New York Stock Exchange.
    Occasionally, events affecting the values of such securities and such
    exchange rates may occur between the times at which they are determined and
    the close of the New York Stock Exchange which would not be reflected in the
    computation of the Fund's net asset value. If events materially affecting
    the value of such securities occur during such period, then these securities
    will be valued at their fair market value as determined in good faith by or
    under the supervision of the Board of Directors.
B.  Securities Transactions, Investment Income and Distributions--Securities
    transactions are accounted for on a trade date basis. Realized gains or
    losses on sales are computed on the basis of specific identification of the
    securities sold. Interest income is recorded as earned from settlement date
    and is recorded on the accrual basis. Dividend income and distributions to
    shareholders are recorded on the ex-dividend date and are paid annually.
C.  Federal Income Taxes--The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.
D.  Expenses--Distribution and transfer agency expenses directly attributable to
    a class of shares are charged to that class' operations. All other expenses
    which are attributable to more than one class are allocated among the
    classes.
E.  Foreign Currency Translations--Portfolio securities and other assets and
    liabilities denominated in foreign currencies are translated into U.S.
    dollar amounts at date of valuation. Purchases and sales of portfolio
    securities and income items denominated in foreign currencies are translated
    into U.S. dollar amounts on the respective dates of such transactions. The
    Fund does not separately account for that portion of the results of
    operations resulting from changes in foreign exchange rates on investments
    and the fluctuations arising from changes in market prices of securities
    held. Such fluctuations are included with the net realized and unrealized
    gain or loss from investments.
F.  Foreign Currency Contracts--A foreign currency contract is an obligation to
    purchase or sell a specific currency for an agreed-upon price at a future
    date. The Fund may enter into a foreign currency contract to attempt to
    minimize the risk to the Fund from adverse changes in the relationship
    between currencies. The Fund may enter into a foreign currency contract for
    the purchase or sale of a security denominated in a foreign currency in
    order to "lock in" the U.S. dollar price of that security. The Fund could be
    exposed to risk if counterparties to the contracts are unable to meet the
    terms of their contracts.
G.  Stock Index Futures Contracts--The Fund may purchase or sell stock index
    futures contracts as a hedge against changes in market conditions. Initial
    margin deposits required upon entering into futures contracts are satisfied
    by the segregation of specific securities or cash, and/or by securing a
    standby letter of credit from a major commercial bank, as collateral, for
    the account of the broker (the Fund's agent in acquiring the futures
    position). During the period the futures contracts are open, changes in the
    value of the contracts are recognized as unrealized gains or losses by
    "marking to market" on a daily basis to reflect the market value of the
    contracts at the end of each day's trading. Variation margin payments are
    made or received depending upon whether unrealized gains or losses are
    incurred. When the contracts are closed, the Fund recognizes a realized gain
    or loss equal to the difference between the proceeds from, or cost of, the
    closing transaction and the Fund's basis in the contract. Risks include the
    possibility of an illiquid market and the change in the value of the
    contracts may not correlate with changes in the value of the securities
    being hedged.
H.  Covered Call Options -- The Fund may write call options, but only on a
    covered basis; that is, the Fund will own the underlying security. Options
    written by the Fund normally will have expiration dates between three and
    nine months from the date written. The exercise price of a call option may
    be below, equal to, or above the current market value of the underlying
    security at the time the option is written. When the Fund writes a covered
    call option, an amount equal to the premium received by the Fund is recorded
    as an asset and an equivalent liability. The amount of the liability is
    subsequently "marked-to-market" to reflect the current market value of the
    option written. The current market value of a written option is the mean
    between the last bid and asked prices on that day. If a written call option
    expires on the stipulated expiration date, or if the Fund enters into a
    closing purchase transaction, the Fund realizes a gain (or a loss if the
    closing purchase transaction exceeds the premium received when the option
    was written) without regard to any unrealized gain or loss on the underlying
    security, and the liability related to such option is extinguished. If a
    written option is exercised, the Fund realizes a gain or a loss from the
    sale of the underlying security and the proceeds of the sale are increased
    by the premium originally received.
         A call option gives the purchaser of such option the right to buy, and
    the writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to

                             AIM CONSTELLATION FUND                           25
<PAGE>   28
    acquire the security which is the subject of the call option at any time
    during the option period. During the option period, in return for the
    premium paid by the purchaser of the option, the Fund has given up the
    opportunity for capital appreciation above the exercise price should the
    market price of the underlying security increase, but has retained the risk
    of loss should the price of the underlying security decline. During the
    option period, the Fund may be required at any time to deliver the
    underlying security against payment of the exercise price. This obligation
    is terminated upon the expiration of the option period or at such earlier
    time at which the Fund effects a closing purchase transaction by purchasing
    (at a price which may be higher than that received when the call option was
    written) a call option identical to the one originally written.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The Company has entered into a master investment agreement with A I M Advisors,
Inc. ("AIM"). Under the terms of the master investment advisory agreement, the
Fund pays an advisory fee to AIM at the annual rate of 1.0% of the first $30
million of the Fund's average daily net assets, plus 0.75% of the Fund's average
daily net assets in excess of $30 million to and including $150 million, plus
0.625% of the Fund's average daily net assets in excess of $150 million. AIM has
agreed to contractually waive a portion of its advisory fees paid by the Fund to
AIM to the extent necessary to reduce the fees paid by the Fund at net asset
levels higher than those currently incorporated in the present advisory fee
schedule. Under the contractual waiver, AIM will receive a fee calculated at the
annual rate of 1.0% of the first $30 million of the Fund's average daily net
assets, plus 0.75% of the Fund's average daily net assets in excess of $30
million to and including $150 million, plus 0.625% of the Fund's average daily
net assets in excess of $150 million to and including $2 billion, plus 0.60% of
the Fund's average daily net assets in excess of $2 billion. During the six
months ended April 30, 1999, AIM waived fees of $1,510,669. The waiver is
contractual and may not be terminated without approval of the Board of
Directors. Under the terms of a master sub-advisory agreement between AIM and
A I M Capital Management, Inc. ("AIM Capital"), AIM pays AIM Capital 50% of the
amount paid by the Fund to AIM.
  The Fund, pursuant to a master administrative services agreement with AIM, has
agreed to reimburse AIM for certain administrative costs incurred in providing
accounting services to the Fund. During the six months ended April 30, 1999, AIM
was reimbursed $165,842 for such services.
  The Fund, pursuant to a transfer agent and shareholder service agreement, has
agreed to pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer
agency and shareholder services to the Fund. During the six months ended April
30, 1999, AFS was paid $5,805,957 with respect to the Fund.
  The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares of the Fund. The Company has adopted
distribution plans pursuant to Rule 12b-1 under the 1940 Act with respect to the
Fund's Class A shares and Class C shares (the "Class A and C Plan"), and the
Fund's Class B shares (the "Class B Plan") (collectively, the "Plans"). The
Fund, pursuant to the Class A and C Plan, pays AIM Distributors compensation at
an annual rate of 0.30% of the average daily net assets of the Class A shares
and 1.00% of the average daily net assets of Class C shares. The Fund, pursuant
to the Class B Plan, pays AIM Distributors compensation at an annual rate of
1.00% of the average daily net assets of the Class B shares. Of these amounts,
the Fund may pay a service fee of 0.25% of the average daily net assets of the
Class A, Class B or C shares to selected dealers and financial institutions who
furnish continuing personal shareholder services to their customers who purchase
and own the appropriate class of shares of the Fund. Any amounts not paid as a
service fee under the Plans would constitute an asset-based sales charge. The
Plans also impose a cap on the total sales charges, including asset-based sales
charges that may be paid by the respective classes. During the six months ended
April 30, 1999, the Class A shares, Class B shares and Class C shares paid AIM
Distributors $20,106,290, $1,803,794, and $482,063, respectively as compensation
under the Plans.
  AIM Distributors received commissions of $1,761,150 from sales of the Class A
shares of the Fund during the six months ended April 30, 1999. Such commissions
are not an expense of the Fund. They are deducted from, and are not included in,
the proceeds from sales of Class A shares. During the six months ended April 30,
1999, AIM Distributors received commissions of $392,190 in contingent deferred
sales charges imposed on the redemptions of Fund shares. Certain officers and
directors of the Company are officers and directors of AIM, AIM Capital, AIM
Distributors, AFS, and FMC.
  During the six months ended April 30, 1999, the Fund paid legal fees of
$12,502 for services rendered by Kramer, Levin, Naftalis & Frankel LLP as
counsel to the Company's directors. A member of that firm is a director of the
Company.

NOTE 3-INDIRECT EXPENSES

During the six months ended April 30, 1999, the Fund received reductions in
transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $91,215 and $18,906, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $110,121 during the six months ended April 30, 1999.

NOTE 4-DIRECTOR'S FEES

Director's fees represent remuneration paid or accrued to each director who is
not an "interested person" of AIM. The Company may invest directors' fees, if so
elected by a director, in mutual fund shares in accordance with a deferred
compensation plan.

NOTE 5-BANK BORROWINGS

The Fund is a participant in a committed line of credit facility with a
syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 1999, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.05% on the unused balance of

the committed line. The commitment fee is allocated among the funds based on
their respective average net assets for the period.

AIM WEINGARTEN FUND OUTPACES
BENCHMARK INDEXES

HOW DID THE FUND PERFORM DURING THE REPORTING PERIOD?
For the six-month reporting period ended April 30, 1999, total return for the
Institutional Class was an impressive 29.78%. Fund performance far outpaced the
gains of benchmark indexes. For the same period, the S&P 500 posted a 22.31%
gain, while the Lipper Growth Funds Index returned 23.71%. Net assets under
management increased by 41% during the last six months for a total of $103.2
million at the reporting period's close.

WHAT WERE THE MAJOR TRENDS IN THE FINANCIAL MARKETS DURING THE REPORTING PERIOD?
At the beginning of the reporting period, fund performance benefited from the
"flight to quality" during last fall's market downturn. Increasing narrowness in
the U.S. financial markets through early 1999 continued the dominance by
large-cap stocks. The Dow closed above 10,000 on March 29, 1999, and surpassed
several other milestones in April.
    The beginning of 1999 was not so hospitable for the technology sector. After
the sector's sterling performance in 1998, many investors began to worry about a
bubble developing, especially in high-flying Internet stocks, the so-called
".com" universe. A sell-off in the technology arena ensued, but the markets
rebounded after first-quarter 1999 earnings reports came in quite strong.

WHAT CONTRIBUTED TO THE FUND'S STRONG GAINS?
We believe that several factors drove the fund's stellar performance. One is
scarcity of earnings in the financial markets. In an environment of moderate or
slightly decelerating economic growth, investors put a premium on growth
companies, and growth stocks tend to outperform other types of stocks. Our
overweight in large-cap stocks, which represented 87% of net assets at the end
of the reporting period, also contributed to the fund's strong showing. In
addition, since last October, we have reduced the fund's total holdings to
approximately 90 names, down from 124. Early in 1998, the fund had the lion's
share of its assets in fast-pace momentum names. However, when the economy
slowed and earnings cooled at mid-year, we culled approximately a third of our
holdings and began to focus on stable core stocks in traditional growth sectors,
such as technology and health care.

WHAT ARE THE DIFFERENCES BETWEEN A CORE HOLDING AND A MOMENTUM HOLDING?
A company may qualify for the fund's portfolio in one of two ways: as a core
holding or as a momentum holding. A core holding is a company that has a very
stable and profitable business model projected to grow by at least 12% over the
next five years. A core holding is expected to outperform over the long term. On
the other hand, a momentum company is one currently enjoying a dramatic surge in
earnings that while probably not sustainable over the long term, exceeds of the
market's near-term growth rate. The fund combines high-quality core companies
with potentially more explosive momentum stocks in a barbell strategy.

WHAT TYPE OF TECHNOLOGY COMPANIES DOES THE FUND OWN?
At the reporting period's close, technology holdings accounted for approximately
36% of net assets. The majority of the fund's technology holdings are
high-quality, dominant brand-name firms. Companies such as AOL and Cisco Systems
continued to do well due to their large size, which has become a strategic
weapon for companies in this sector. Larger technology companies have more money
to spend on research and development, which in turn drives further technological
advancement. In this sector, being small or midcap may not necessarily be an
advantage. Having money to spend on research and development and the ability to
provide global reach to customers have become the main thrusts behind a
technology business's success.

WHAT TYPE OF HEALTH-CARE COMPANIES DO YOU FAVOR?
Our health-care holdings, which accounted for 18.4% of net assets on April 30,
were split among diversified health-care companies, major pharmaceuticals and
medical-equipment makers. Our investment in this sector has been driven by
long-term demographic trends. The aging population needs more and more health

care. Worldwide drug sales are rising at a rate of 8% to 10% a year and
medical-device sales at 7% annually. In the health-care arena, we are seeing a
continuation of the "size matters" theme. The costs to bring a new drug to
market total in the neighborhood of $1 billion. So bigger firms, such as
Warner-Lambert and Abbott Laboratories, have a clear advantage over their
smaller counterparts. In addition, these larger companies already have a
foothold in the consumer products markets. We believe very strongly in this
sector as a long-term growth vehicle.

WHAT IS YOUR OUTLOOK FOR THE FUTURE?
Four months into 1999, fears of a recession in the United States have faded. In
fact, most economists are betting on continued steady growth, with low inflation
and high employment. International markets have stabilized as countries slowly
get a grip on their economies, leading analysts to believe that the worst is
over. Domestically, interest rates, another key factor supporting a bullish
outlook, are likely to remain quite steady, thanks to the Federal Reserve
Board's watchful guard. To the extent that these factors remain in place, the
investing environment for the fund continues to be favorable.

NOTES TO FINANCIAL STATEMENTS

APRIL 30, 1999
(UNAUDITED)

NOTE 1-SIGNIFICANT ACCOUNTING POLICIES

AIM Weingarten Fund (the "Fund") is a series portfolio of AIM Equity Funds, Inc.
(the "Company"). The Company is a Maryland corporation registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
series management investment company consisting of nine separate portfolios. The
Fund currently offers four different classes of shares: Class A shares, Class B
shares, Class C shares and the Institutional Class. Class A shares are sold with
a front-end sales charge. Class B shares and Class C shares are sold with a
contingent deferred sales charge. Matters affecting each portfolio or class will
be voted on exclusively by the shareholders of such portfolio or class. The
assets, liabilities and operations of each portfolio are accounted for
separately. Information presented in these financial statements pertains only to
the Fund. The Fund's investment objective is to seek growth of capital.
  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 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. The
following is a summary of significant accounting policies followed by the Fund
in the preparation of its financial statements.

A.  Security Valuations--A security listed or traded on an exchange (except
    convertible bonds) is valued at its last sales price on the exchange where
    the security is principally traded, or lacking any sales on a particular
    day, the security is valued at the closing bid price on that day. Each
    security traded in the over-the-counter market (but not including securities
    reported on the NASDAQ National Market System) is valued at the mean between
    the last bid and asked prices based upon quotes furnished by market makers
    for such securities. Each security reported on the NASDAQ National Market
    System is valued at the last sales price on the valuation date or absent a
    last sales price, at the closing bid price. Debt obligations (including
    convertible bonds) are valued on the basis of prices provided by an
    independent pricing service. Prices provided by the pricing service may be
    determined without exclusive reliance on quoted prices, and may reflect
    appropriate factors such as yield, type of issue, coupon rate and maturity
    date. Securities for which market quotations are not readily available or
    are questionable are valued at fair value as determined in good faith by or
    under the supervision of the Company's officers in a manner specifically
    authorized by the Board of Directors of the Company. Short-term obligations
    having 60 days or less to maturity are valued at amortized cost which
    approximates market value. Generally, trading in foreign securities is
    substantially completed each day at various times prior to the close of the
    New York Stock Exchange. The values of such securities used in computing the
    net asset value of the Fund's shares are determined as of such times.
    Foreign currency exchange rates are also generally determined prior to the
    close of the New York Stock Exchange. Occasionally, events affecting the
    values of such securities and such exchange rates may occur between the
    times at which they are determined and the close of the New York Stock
    Exchange which would not be reflected in the computation of the Fund's net
    asset value. If events materially affecting the value of such securities
    occur during such period, then these securities will be valued at their fair
    market value as determined in good faith by or under the supervision of the
    Board of Directors.
B.  Foreign Currency Translations--Portfolio securities and other assets and
    liabilities denominated in foreign currencies are translated into U.S.
    dollar amounts at date of valuation. Purchases and sales of portfolio
    securities and income items denominated in foreign currencies are translated
    into U.S. dollar amounts on the respective dates of such transactions. The
    Fund does not separately account for that portion of the results of
    operations resulting from changes in foreign exchange rates on investments
    and the fluctuations arising from changes in market prices of securities
    held. Such fluctuations are included with the net realized and unrealized
    gain or loss from investments.
C.  Foreign Currency Contracts--A foreign currency contract is an obligation to
    purchase or sell a specific currency for an agreed-upon price at a future
    date. The Fund may enter into a foreign currency contract to attempt to
    minimize the risk to the Fund from adverse changes in the relationship
    between currencies. The Fund may enter into a foreign currency contract for
    the purchase or sale of a security denominated in a foreign currency in
    order to "lock in" the U.S. dollar price of that security. The Fund could be
    exposed to risk if counterparties to the contracts are unable to meet the
    terms of their contracts.
D.  Stock Index Futures Contracts--The Fund may purchase or sell stock index
    futures contracts as a hedge against changes in market conditions. Initial
    margin deposits required upon entering into futures contracts are satisfied
    by the segregation of specific securities or cash, and/or by securing a
    standby letter of credit from a major commercial bank, as collateral, for
    the account of the broker (the Fund's agent in acquiring the futures
    position). During the period the futures contracts are open, changes in the
    value of the contracts are recognized as unrealized gains or losses by
    "marking to market" on a daily basis to reflect the market value of the
    contracts at the end of each day's trading. Variation margin payments are
    made or received depending upon whether unrealized gains or losses are
    incurred. When the contracts are closed, the Fund recognizes a realized gain
    or loss equal to the difference between the proceeds from, or cost of, the
    closing transaction and the Fund's basis in the contract. Risks include the
    possibility of an illiquid market and that the change in the value of the
    contracts may not correlate with changes in the value of the securities
    being hedged.
E.  Covered Call Options--The Fund may write call options, but only on a covered
    basis; that is, the Fund will own the underlying security. Options written
    by the Fund normally will have expiration dates between three and nine
    months from the date written. The exercise price of a call option may be
    below, equal to, or above the current market value of the underlying
    security at the time the option is written. When the Fund writes a covered
    call option, an amount equal to the premium received by the Fund is recorded
    as an asset and an equivalent liability. The amount of the liability is
    subsequently "marked-to-market" to reflect the current market value of the
    option

 38                           AIM WEINGARTEN FUND
<PAGE>   41

    written. The current market value of a written option is the mean between
    the last bid and asked prices on that day. If a written call option expires
    on the stipulated expiration date, or if the Fund enters into a closing
    purchase transaction, the Fund realizes a gain (or a loss if the closing
    purchase transaction exceeds the premium received when the option was
    written) without regard to any unrealized gain or loss on the underlying
    security, and the liability related to such option is extinguished. If a
    written option is exercised, the Fund realizes a gain or a loss from the
    sale of the underlying security and the proceeds of the sale are increased
    by the premium originally received.
      A call option gives the purchaser of such option the right to buy, and the
    writer (the Fund) the obligation to sell, the underlying security at the
    stated exercise price during the option period. The purchaser of a call
    option has the right to acquire the security which is the subject of the
    call option at any time during the option period. During the option period,
    in return for the premium paid by the purchaser of the option, the Fund has
    given up the opportunity for capital appreciation above the exercise price
    should the market price of the underlying security increase, but has
    retained the risk of loss should the price of the underlying security
    decline. During the option period, the Fund may be required at any time to
    deliver the underlying security against payment of the exercise price. This
    obligation is terminated upon the expiration of the option period or at such
    earlier time at which the Fund effects a closing purchase transaction by
    purchasing (at a price which may be higher than that received when the call
    option was written) a call option identical to the one originally written.
F.  Put Options--The Fund may purchase put options. By purchasing a put option,
    the Fund obtains the right (but not the obligation) to sell the option's
    underlying instrument at a fixed strike price. In return for this right, a
    Fund pays an option premium. The option's underlying instrument may be a
    security, or a futures contract. Put options may be used by a Fund to hedge
    securities it owns by locking in a minimum price at which the Fund can sell.
    If security prices fall, the put option could be exercised to offset all or
    a portion of the Fund's resulting losses. At the same time, because the
    maximum the Fund has at risk is the cost of the option, purchasing put
    options does not eliminate the potential for the Fund to profit from an
    increase in the value of the securities hedged.
G.  Securities Transactions, Investment Income and Distributions--Securities
    transactions are accounted for on a trade date basis. Realized gains or
    losses on sales are computed on the specific identification of securities
    sold. Interest income is recorded as earned from settlement date and is
    recorded on the accrual basis. Dividend income and distributions to
    shareholders are recorded on the ex-dividend date and are paid annually.
H.  Federal Income Taxes--The Fund intends to comply with the requirements of
    the Internal Revenue Code necessary to qualify as a regulated investment
    company and, as such, will not be subject to federal income taxes on
    otherwise taxable income (including net realized capital gains) which is
    distributed to shareholders. Therefore, no provision for federal income
    taxes is recorded in the financial statements.
I.  Expenses--Distribution and transfer agency expenses directly attributable to
    a class of shares are charged to that class' operations. All other expenses
    which are attributable to more than one class are allocated among the
    classes.

NOTE 2-ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES

   The Company has entered into a master investment advisory agreement with A I
M Advisors, Inc. ("AIM"). The terms of the master investment advisory agreement
provide that the Fund shall pay an advisory fee to AIM at an annual rate of 1.0%
of the first $30 million of the Fund's average daily net assets, plus 0.75% of
the Fund's average daily net assets in excess of $30 million to and including
$350 million, plus 0.625% of the Fund's average daily net assets in excess of
$350 million. AIM is currently contractually waiving a portion of its advisory
fees payable by the Fund to AIM to the extent necessary to reduce the fees paid
by the Fund at net asset levels higher than those currently incorporated in the
present advisory fee schedule. AIM will receive a fee calculated at the annual

of a master sub-advisory agreement between AIM and A I M Capital Management,
Inc. ("AIM Capital"), AIM pays AIM Capital 50% of the amount paid by the Fund to
AIM.
   The Fund, pursuant to a master administrative services agreement with AIM,
has agreed to reimburse AIM for certain administrative costs incurred in
providing accounting services to the Fund. During the six months ended April 30,
1999, AIM was reimbursed $109,744 for such services.
  The Fund, pursuant to a transfer agent and service agreement, has agreed to
pay A I M Fund Services, Inc. ("AFS") a fee for providing transfer agency and
shareholder services to the Fund. During the six months ended April 30, 1999,
AFS was paid $2,719,811 for such services.
  The Company has entered into master distribution agreements with A I M
Distributors, Inc. ("AIM Distributors") to serve as the distributor for the
Class A, Class B and Class C shares of the Fund. The Company has adopted
distribution plans pursuant to Rule 12b-1 under the 1940 Act with respect to the
Fund's Class A shares and Class C shares (the "Class A and C Plan"), and the
Fund's Class B shares (the "Class B Plan")(collectively, the "Plans"). The Fund,
pursuant to the Class A and C Plan, pays AIM Distributors compensation at an
annual rate of 0.30% of the average daily net assets of the Class A shares and
1.00% of the average daily net assets of Class C shares. The Fund, pursuant to
the Class B Plan, pays AIM Distributors compensation at an annual rate of 1.00%
of the average daily net assets of the Class B shares. Of these amounts, the
Fund may pay a service fee of 0.25% of the average daily net assets of the Class
A, Class B or C shares to selected dealers and financial institutions who
furnish continuing personal shareholder services to their customers who purchase
and own the appropriate class of shares of the Fund. Any amounts not paid as a
service fee under the Plans would constitute an asset-based sales charge. The
Plans also impose a cap on the total sales charges, including asset-based sales
charges that may be paid by the respective classes. During the six months ended
April 30, 1999,

                              AIM WEINGARTEN FUND                             39

the Class A, Class B and Class C shares paid AIM Distributors $10,721,830,
$4,489,959, and $185,840, respectively, as compensation under the Plans.
  AIM Distributors received commissions of $1,081,813 from sales of the Class A
shares of the Fund during the six months ended April 30, 1999. Such commissions
are not an expense of the Fund. They are deducted from, and are not included in,
the proceeds from sales of Class A shares. During the six months ended April 30,
1999, AIM Distributors received commissions of $118,545 in contingent deferred
sales charges imposed on redemptions of Fund shares. Certain officers and
directors of the Company are officers and directors of AIM, AIM Capital, AIM
Distributors, AFS and FMC.
  During the six months ended April 30, 1999, the Fund paid legal fees of $7,269
for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the
Company's directors. A member of that firm is a director of the Company.

transfer agency fees from AFS (an affiliate of AIM) and reductions in custodian
fees of $53,442 and $20,912, respectively, under expense offset arrangements.
The effect of the above arrangements resulted in a reduction of the Fund's total
expenses of $74,354 during the six months ended April 30, 1999.

NOTE 4-DIRECTORS' FEES

Directors' fees represent remuneration paid or accrued to each director who is
not an "interested person" of AIM. The Company invests directors' fees, if so
elected by a director, in mutual fund shares in accordance with a deferred
compensation plan.

NOTE 5-BANK BORROWINGS

The Fund is a participant in a committed line of credit facility with a
syndicate administered by The Chase Manhattan Bank. The Fund may borrow up to
the lesser of (i) $1,000,000,000 or (ii) the limits set by its prospectus for
borrowings. The Fund and other funds advised by AIM which are parties to the
line of credit may borrow on a first come, first served basis. During the six
months ended April 30, 1999, the Fund did not borrow under the line of credit
agreement. The funds which are party to the line of credit are charged a
commitment fee of 0.05% on the unused balance of the committed line. The
commitment fee is allocated among the funds based on their respective average
net assets for the period.
