- --------------------------------------------------------------------------------
 
This mutual fund (the "Fund") is designed to provide current income exempt from
federal income taxes and Maryland state and local income taxes consistent with
preservation of principal within an intermediate-term maturity structure. The
Fund will invest primarily in municipal obligations issued by the State of
Maryland and its political subdivisions, agencies or instrumentalities.
   
Class A Shares of the Fund ("Class A Shares") are available through your
securities dealer or the Fund's transfer agent (See "How to Invest in the
Fund.")

This Prospectus sets forth basic information that investors should know about
the Fund prior to investing and should be retained for future reference. A
Statement of Additional Information dated August 1, 1997 as supplemented
through September 1, 1997 has been filed with the Securities and Exchange
Commission (the "SEC") and is hereby incorporated by reference. It is available
upon request and without charge by calling the Fund at (800) 767-FLAG.

 * Purchases of $1 million or more by persons not otherwise eligible for sales
   load waivers are not subject to an initial sales charge; however, a
   contingent deferred sales charge of 0.50% may be imposed on such purchases.
   (See "How to Invest in the Fund -- Offering Price.")
** The Fund's investment advisor currently intends to waive its fee or to
   reimburse the Fund on a voluntary basis to the extent required so that
   Total Fund Operating Expenses do not exceed 0.70% of the Fund's average
   daily net assets. Absent fee waivers and/or reimbursements, Management Fees
   would be .35%, Other Expenses would be 0.74% and the Fund's Total Fund
   Operating Expenses would be 1.34% of the Class A Shares' average daily net
   assets.

 * The Example is based on Total Fund Operating Expenses, net of fee waivers
   and reimbursements. Absent such fee waivers and reimbursements, expenses
   would be higher.

The Expenses and Example should not be considered a representation of future
expenses. Actual expenses may be greater or less than those shown.

     The purpose of the foregoing table is to describe the various costs and
expenses that Fund investors may pay directly and indirectly. A person who
purchases Class A Shares through a financial institution may be charged
separate fees by the financial institution.

     The rules of the SEC require that the maximum sales charge (in the Fund's
case, 1.50% of the offering price) be reflected in the above table. However,
certain investors may qualify for reduced sales charges or no sales charge at
all. (See "How to Invest in the Fund -- Offering Price.") Due to the continuous
nature of Rule 12b-1 fees, long-term shareholders of the Fund may pay more than
the equivalent of the maximum front-end sales charges permitted by the Conduct
Rules of the National Association of Securities Dealers, Inc.

INVESTMENT PROGRAM

- --------------------------------------------------------------------------------
Investment Objective, Policies and Risk
Considerations

      The Fund seeks to provide current income exempt from federal income taxes
and Maryland state and local income taxes consistent with preservation of
principal within an intermediate-term maturity structure. There is no assurance
this objective will be met.
   
      Under normal conditions, the Fund expects to be as fully invested as
practicable in obligations that, in the opinion of bond counsel to the issuers,
produce interest exempt from federal income tax and Maryland state and local
income tax and at least 65% of the Fund's total assets will be invested in
securities of Maryland issuers. These include municipal obligations issued by
the State of Maryland and its political subdivisions, agencies or
instrumentalities. The Fund may invest up to 35% of its assets in obligations
of other issuers of securities the interest on which is exempt from Maryland
state and local taxes. These issuers would include territories or possessions
of the United States. However, the Fund has no present intention to invest in
securities issued by such territories or possessions.

      As a matter of fundamental policy, under normal conditions, the Fund will
invest at least 80% of its total assets in securities the interest on which is
exempt from federal and Maryland state and local income taxes and 80% of the
Fund's assets will be invested in municipal securities the income from which is
not subject to the alternative minimum tax. Income derived from securities
subject to the alternative minimum tax is not included when computing income
exempt from federal and Maryland state and local income taxes. Under normal
conditions, the Fund may invest up to 20% of its net assets in municipal
securities, the income from which is not exempt from Maryland state and local
income taxes. For temporary, defensive purposes when, in the opinion of the
Fund's investment advisor (the "Advisor"), securities exempt from Maryland
state and local income tax are not readily available or of sufficient quality,
the Fund can invest up to 100% of its assets in securities that pay interest
that is exempt only from federal income taxes or in taxable U.S. Treasury
securities.

      The Fund is a non-diversified investment company, which means that more
than 5% of its assets may be invested in each of one or more issuers. Since a
relatively high percentage of assets of the Fund may be invested in the
obligations of a limited number of issuers, the value of shares of the Fund may
be more susceptible to any single economic, political or regulatory occurrence
than the shares of a diversified investment company would be. The Fund intends
to satisfy the diversification requirements necessary to qualify as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code").
    

<PAGE>

      The Fund currently contemplates that it will not invest more than 25% of
its total assets (at market value at the time of purchase) in municipal
securities, the interest on which is paid from revenues of projects with
similar characteristics. See also "Special Considerations Relating To Maryland
Municipal Securities."

      Under normal circumstances the Fund's portfolio will have a dollar
weighted average maturity of between 3 and 10 years. The value of obligations
purchased by the Fund will change as interest rates change. Thus, a decrease in
interest rates generally will result in an increase in the value of shares of
the Fund. Conversely, an increase in interest rates will generally result in a
decrease in the value of the shares of the Fund. The magnitude of these
fluctuations will be greater as the average maturity of the Fund increases.
   
      Municipal notes in which the Fund may invest will be limited to those
obligations (i) that are rated MIG-1 or VMIG-1 at the time of investment by
Moody's Investors Service, Inc. ("Moody's"), (ii) that are rated SP-1 at the
time of investment by Standard & Poor's Ratings Group ("S&P"), or (iii) that,
if not rated by S&P or Moody's, are of comparable quality in the Advisor's
judgment. Municipal bonds in which the Fund may invest must be rated BBB or
better by S&P or Baa or better by Moody's at the time of investment or, if
unrated by S&P or Moody's must be of comparable quality in the Advisor's
judgment. Securities rated Baa or BBB are deemed to have speculative
characteristics. Tax-exempt commercial paper will be limited to investments in
obligations that are rated at least A-1 by S&P or Prime-1 by Moody's at the
time of investment or, if unrated by S&P or Moody's, are of comparable quality
in the Advisor's judgment. These ratings may be based in part on credit support
provided by a bank or other entity. Accordingly, a decline in the
creditworthiness of the entity providing such support could affect the rating
of the security, as well as the payment of interest and principal. For a
description of the above ratings, see the Appendix to the Statement of
Additional Information.
    
      The Fund may also enter into futures contracts and options on futures
contracts, although it has no present intention to do so. Gains recognized by
the Fund from such transactions would constitute taxable income to
shareholders.


                                                                               3
- --------------------------------------------------------------------------------
<PAGE>

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

      The Fund may also purchase variable and floating rate demand notes and
bonds. The Advisor will invest in commitments to purchase securities on a
"when-issued" basis and reserves the right to engage in "put" transactions on a
daily, weekly or monthly basis.

Municipal Securities

      Municipal securities that the Fund may purchase consist of (i) debt
obligations issued by or on behalf of public authorities to obtain funds to be
used for various public facilities, for refunding outstanding obligations, for
general operating expenses and for lending such funds to other public
institutions and facilities, and (ii) certain private activity and industrial
development bonds issued by or on behalf of public authorities to obtain funds
to provide for the construction, equipment, repair or improvement of privately
operated facilities. Municipal notes include general obligation notes, tax
anticipation notes, revenue anticipation notes, bond anticipation notes,
certificates of indebtedness, demand notes, construction loan notes and
participation interests therein. Municipal bonds include general obligation
bonds, revenue or special obligation bonds, private activity bonds, industrial
development bonds and participation interests therein. General obligation bonds
are backed by the taxing power of the issuing municipality. Revenue bonds are
backed by the revenues of a project or facility, tolls from a toll bridge, or
lease payments, for example. The payment of principal and interest on private
activity and industrial development bonds generally is dependent solely on the
ability of the facility's user to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment.

   
      The Fund may purchase municipal lease obligations, including certificates
of participation ("COPs") in municipal leases. The Fund may acquire municipal
lease obligations that may be assigned by the lessee to another party provided
the obligation continues to provide tax-exempt interest. The Fund will not
purchase municipal lease obligations to the extent it holds municipal lease
obligations and illiquid securities in an amount exceeding 10% of its net
assets unless the Advisor determines that the municipal lease obligations are
liquid pursuant to guidelines established by the Board of Directors of the
Fund. Pursuant to these guidelines, the Advisor, in making this liquidity
determination, will consider, among other factors, the strength and nature of
the secondary market for such obligations, the prospect for its future
marketability and whether such obligations are rated. The Fund expects that it
will purchase only rated municipal lease obligations. In addition, the Fund may
purchase COPs representing interests in other municipal securities (such as
industrial development bonds). (See "Participation Interests.")
   
      Municipal obligations purchased by the Fund that fall below the above
rating criteria after the purchase by the Fund shall be sold as promptly as
possible consistent with orderly disposition.
    

<PAGE>

Insured Obligations

      The Fund may invest in obligations that are insured as to the scheduled
payment of all installments of principal and interest as they fall due. The
purpose of this insurance is to minimize credit risks to the Fund and its
shareholders associated with defaults in Maryland municipal obligations owned
by the Fund. This insurance does not insure against market risk and therefore
does not guarantee the market value of the obligations in the Fund's investment
portfolio upon which the net asset value of the Fund's shares is based. The
market value will continue to fluctuate in response to fluctuations in interest
rates or the bond market. Similarly, this insurance does not cover or guarantee
the value of the shares of the Fund. The ratings of the insured obligations may
be based in part on insurance provided by an insurance company. Accordingly, a
decline in the creditworthiness of the insurance company providing the
insurance could affect the rating of the security, as well as the payment of
interest and principal.

Participation Interests
   
      The Fund may invest in COPs representing participation interests in
municipal securities (such as AMT-Subject Bonds). A participation interest (i)
may pay a fixed, floating or variable rate of interest; (ii) gives the
purchaser an undivided interest in the municipal securities in the proportion
that the Fund's participation interest bears to the total principal amount of
the municipal securities; and (iii) provides a demand repurchase feature. Each
participation is backed by an irrevocable letter of credit or guarantee of a
bank that meets the prescribed quality standards of the Fund. The Fund has the
right to sell the instrument back to the issuing bank or draw on the letter of
credit on demand for all or any part of the Fund's participation interest in
the municipal security, plus accrued interest. Banks will retain or receive a
service fee, letter of credit fee and a fee for issuing repurchase commitments
in an amount equal to the excess of the interest paid on the municipal
securities over the negotiated yield at which the instruments were purchased by
the Fund. Participation interests in the form to be purchased by the Fund are
new instruments, and no ruling of the Internal Revenue Service has been secured
relating to their tax-exempt status. The Fund intends to purchase participation
interests based upon opinions of counsel to the issuer to the effect that
income from the participation interests is tax-exempt to the Fund. For purposes
of complying with diversification requirements, the Fund will treat both the
trust, or

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

similar entity established to issue COPs, and the issuers of the underlying
municipal securities as issuers. Also, the Fund will limit its investments in
COPs to less than 25% of its total assets.

Repurchase Agreements

   
      The Fund may agree to purchase U.S. Treasury securities from creditworthy
financial institutions, such as banks and broker-dealers, subject to the
seller's agreement to repurchase the securities at an established time and
price. Default by or bankruptcy proceedings with respect to the seller may,
however, expose the Fund to possible loss because of adverse market action or
delay in connection with the disposition of the underlying obligations.
    

Variable and Floating Rate Demand
Obligations
   
      The Fund may purchase variable and floating rate demand notes and bonds,
which are tax-exempt obligations normally having stated maturities in excess of
one year, but which permit the holder to demand payment of principal either at
any time or at specified intervals. The interest rates on these obligations
fluctuate from time to time in response to changes in the market interest
rates. Frequently, such obligations are secured by letters of credit or other
credit support arrangements provided by banks. Where these obligations are not
secured by letters of credit or other credit support arrangements, the Fund's
right to redeem will be dependent on the ability of the borrower to pay
principal and interest on demand. Each demand note and bond purchased by the
Fund will meet the quality criteria established for the purchase of other
municipal obligations. The Fund will not invest more than 10% of its net assets
in floating or variable rate demand obligations as to which the Fund cannot
exercise the demand feature on less than seven days' notice if there is no
secondary market available for these obligations.
    

When-Issued Securities

      When-issued securities are securities purchased for delivery beyond the
normal settlement date at a stated price and yield. The Fund will generally not
pay for such securities or start earning interest on them until they are
received. When-issued commitments will not be used for speculative purposes and
will be entered into only with the intention of actually acquiring the
securities. The securities so purchased or sold are subject to market
fluctuation so, at the time of delivery of the securities, their value may be
more or less than the purchase or sale price. The Fund will ordinarily invest
no more than 40% of its net assets at any time in municipal obligations
purchased on a when-issued basis.

Special Considerations Relating to Maryland
Municipal Securities

      The Fund's concentration in securities issued by the State of Maryland
and its political subdivisions, agencies and instrumentalities involves greater
risk than a fund broadly invested across many states and municipalities. In
particular, changes in economic conditions and governmental policies of the
State of Maryland and its municipalities could adversely affect the value of
the Fund and the securities held by it. For a further description of these
risks, see "Risk Factors Associated with a Maryland Portfolio" in the Statement
of Additional Information.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
   
      The Fund's investment program is subject to a number of restrictions that
reflect both self-imposed standards and federal regulatory limitations.

1) As a matter of fundamental policy, the Fund will not concentrate 25% or more
   of its total assets in securities of issuers in any one industry, provided
   that this limitation does not apply to investments in tax-exempt
   securities issued by governments or political subdivisions of governments
   (for these purposes the U.S. Government and its agencies and
   instrumentalities are not considered an issuer). This restriction may not
   be changed without shareholder approval.

2) Additionally, the Fund will not invest more than 10% of its net assets in
   illiquid securities, including repurchase agreements with maturities of
   greater than seven days. This restriction may be changed by a vote of the
   Board of Directors.
    
      The Fund is subject to further investment restrictions that are set forth
in the Statement of Additional Information.


                                                                               5

HOW TO INVEST IN THE FUND

- --------------------------------------------------------------------------------
   
      Class A Shares may be purchased from the Fund's distributor (the
"Distributor"), through any securities dealer that is authorized to distribute
Shares ("Participating Dealers"), or through any financial institution that has
entered into a shareholder servicing agreement with the Fund ("Shareholder
Servicing Agents"). Class A Shares may also be purchased by completing the
Application Form attached to this Prospectus and returning it, together with
payment of the purchase price (including any applicable front-end sales
charge), to the address shown on the Application Form.
    
      The minimum initial investment is $2,000, except that the minimum initial
investment for shareholders of any other Flag Investors fund or class is $500
and the minimum initial investment for participants in the Fund's Automatic
Investing Plan is $250. Each subsequent investment must be at least $100,
except that the minimum subsequent investment under the Fund's Automatic
Investing Plan is $250 for quarterly investments and $100 for monthly
investments. (See "Purchases through Automatic Investing Plan" below.)
   
      Orders for purchases of Shares are accepted on any day on which the New
York Stock Exchange is open for business (a "Business Day"). The Fund reserves
the right to suspend the sale of Shares at any time at the discretion of the
Distributor or the Advisor. Purchase orders for Class A Shares will be executed
at a per share purchase price equal to the net asset value next determined
after receipt of the purchase order plus any applicable front-end sales charge
(the "Offering Price") on the date such net asset value is determined (the
"Purchase Date"). Purchases made by mail must be accompanied by payment of the
Offering Price. Purchases made through the Distributor or a Participating
Dealer or Shareholder Servicing Agent must be in accordance with such entity's
payment procedures. The Distributor may, in its sole discretion, refuse to
accept any purchase order.

      The net asset value per share is determined daily as of the close of the
New York Stock Exchange, which is ordinarily 4:00 p.m. (Eastern Time), on each
Business Day. Net asset value per share of a class is calculated by valuing its
share of the Fund's assets, deducting all liabilities attributable to that
class, and dividing the resulting amount by the number of then outstanding
shares of the class. For this purpose, portfolio securities are given their
market value where feasible. Securities or other assets for which market
quotations are not readily available are valued at their fair value as
determined in good faith under procedures established from time to time and
monitored by the Fund's Board of Directors. Such procedures may include the use
of an independent pricing service, which uses prices based upon yields or
prices of securities of comparable quality, coupon, maturity and type;
indications as to values from dealers; and general market conditions. Debt
obligations with maturities of 60 days or less are valued at amortized cost,
which constitutes fair value as determined by the Fund's Board of Directors.
    

<PAGE>

Offering Price
   
      Class A Shares may be purchased from the Distributor, Participating
Dealers or Shareholder Servicing Agents at the Offering Price, which includes a
sales charge that is calculated as a percentage of the Offering Price and
decreases as the amount of purchase increases, as shown below:
    

   
                                  Sales Charge           
                                    as % of              Dealer

                            Offering    Net Amount       as % of

$500,000 - $999,999 ......   1.00%        1.01%           0.75%
$1,000,000 and over ......   None*        None*           None*
    

   
- -----------
* Purchases of $1 million or more may be subject to a contingent deferred sales
  charge. (See below.) The Distributor may make payments to dealers in the
  amount of .50% of the Offering Price.

      A shareholder who purchases additional Shares may obtain reduced sales
charges as set forth in the table above through a right of accumulation. In
addition, an investor may obtain reduced sales charges as set forth above
through a right of accumulation of purchases of Class A Shares and purchases of
shares of other Flag Investors funds with the same or a higher front-end sales
charge. The applicable sales charge will be determined based on the total of
(a) the shareholder's current purchase plus (b) an amount equal to the then
current net asset value or cost, whichever is higher, of all Flag Investors
shares described above and any Flag Investors Class D shares held by the
shareholder. To obtain the reduced sales charge through a right of
accumulation, the shareholder must provide the Distributor, either directly or
through a Participating Dealer or Shareholder Servicing Agent, as applicable,
with sufficient information to verify that the shareholder has such a right.
The Fund may amend or terminate this right of accumulation at any time as to
subsequent purchases.

      The term "purchase" refers to an individual purchase by a single
purchaser, or to concurrent purchases, which will be aggregated by a purchaser,
the purchaser's spouse and their children under the age of 21 years purchasing
Class A Shares for their own account.
    


6
- --------------------------------------------------------------------------------
<PAGE>


- --------------------------------------------------------------------------------
   
      An investor may also obtain the reduced sales charges shown above by
executing a written Letter of Intent which states the investor's intention to
invest at least $100,000 within a 13-month period in Class A Shares. Each
purchase of Class A Shares under a Letter of Intent will be made at the
Offering Price applicable at the time of such purchase to the full amount
indicated in the Letter of Intent. A Letter of Intent is not a binding
obligation upon the investor to purchase the full amount indicated. The minimum
initial investment under a Letter of Intent is 5% of the full amount. Class A
Shares purchased with the first 5% of the full amount will be held in escrow
(while remaining registered in the name of the investor) to secure payment of
the higher sales charge applicable to the Class A Shares actually purchased if
the full amount indicated is not invested. Such escrowed Class A Shares will be
involuntarily redeemed to pay the additional sales charge, if necessary. When
the full amount indicated has been purchased, the escrowed Shares will be
released. An investor who wishes to enter into a Letter of Intent in
conjunction with an investment in Class A Shares may do so by completing the
appropriate section of the Application Form attached to this Prospectus.

      No sales charge will be payable at the time of purchase on investments of
$1 million or more. However, a contingent deferred sales charge may be imposed
on such investments in the event of a share redemption within 24 months
following the share purchase, at the rate of .50% on the lesser of the value of
the Class A Shares redeemed or the total cost of such shares. No contingent
deferred sales charge will be imposed on purchases of $3 million or more of
Class A Shares redeemed within 24 months of purchase if the Participating
Dealer and the Distributor have entered into an agreement under which the
Participating Dealer agrees to return any payments received on the sale of such
shares. In determining whether a contingent deferred sales charge is payable,
and, if so, the amount of the charge, it is assumed that Class A Shares not
subject to such charge are the first redeemed followed by other Class A Shares
held for the longest period of time.

      The Fund may sell Class A Shares at net asset value (without sales
charge) to the following: (i) banks, bank trust departments, registered
investment advisory companies, financial planners and broker-dealers purchasing
Class A Shares on behalf of their fiduciary and advisory clients, provided such
clients have paid an account management fee for these services (investors may
be charged a fee if they effect transactions in Fund shares through a broker or
agent); (ii) qualified retirement plans; (iii) participants in a Flag Investors
fund payroll savings plan program; (iv) investors who have redeemed Shares, or
shares of any other mutual fund in the Flag Investors family of funds with the
same or a higher front-end sales charge, in an amount that is not more than the
total redemption proceeds, provided that the purchase is within 90 days after
the redemption; and (v) current or retired Directors of the Fund, and directors
and employees (and their immediate families) of the Advisor, the Distributor,
Participating Dealers and their respective affiliates.
    

<PAGE>
   

      Class A Shares may also be purchased through a Systematic Purchase Plan.
An investor who wishes to take advantage of such a plan should contact the
Distributor, a Participating Dealer or Shareholder Servicing Agent.

Purchases by Exchange

      As permitted pursuant to any rule, regulation or order promulgated by the
SEC, shareholders of Class A shares of Flag Investors Short-Intermediate Income
Fund, Inc. and shareholders of other mutual funds in the Flag Investors family
of funds with a higher front-end sales charge, may exchange their shares of
those funds for an equal dollar amount of Class A Shares. Class A Shares issued
pursuant to this offer will not be subject to the sales charges described above
or any other charge. Shareholders of Flag Investors Cash Reserve Prime Class A
Shares may exchange into Class A Shares upon payment of the difference in sales
charges, as applicable.

      When a shareholder acquires Class A Shares through an exchange from
another fund in the Flag Investors family of funds, the Fund will combine the
period for which the original shares were held prior to the exchange with the
holding period of the Class A Shares acquired in the exchange for purposes of
determining what, if any, contingent deferred sales charge is applicable upon a
redemption of any such shares.
    
      The net asset value of shares purchased and redeemed in an exchange
request received on a Business Day will be determined on the same day, provided
that the exchange request is received prior to 4:00 p.m. (Eastern Time), or the
close of the New York Stock Exchange, whichever is earlier. Exchange requests
received after 4:00 p.m. (Eastern Time) will be effected on the next Business
Day.
   
      Shareholders of any mutual fund not affiliated with the Fund who have
paid a sales charge may exchange shares of such fund for an equal dollar amount
of Shares by submitting to the Distributor or a Participating Dealer the
proceeds of the redemption of such shares, together with evidence of the
payment of a sales charge and the source of such proceeds. Class A Shares
issued pursuant to this offer will not be subject to the sales charges
described above or any other charge.
    


                                                                               7
- --------------------------------------------------------------------------------
<PAGE>

- --------------------------------------------------------------------------------
   
      In addition, shareholders may exchange their Class A Shares for an equal
dollar amount of shares of any other mutual fund in the Flag Investors family
of funds with a higher front-end sales charge. In connection with such
exchange, shareholders will be required to pay the difference between the sales
charge paid on Class A Shares and the sales charge applicable to the purchase
of the shares of such other fund, except that the exchange will be made at net
asset value (without payment of any sales charge) if the Class A Shares have
been held for more than 24 months following the purchase date.

      The exchange privilege with respect to other Flag Investors funds may
also be exercised by telephone. (See "Telephone Transactions" below). The Fund
may modify or terminate these offers of exchange at any time on 60 days' prior
written notice to shareholders and the exchange offers set forth herein are
expressly subject to modification or termination.
    
Purchases Through Automatic Investing Plan
   
      Shareholders may purchase Class A Shares regularly by means of an
Automatic Investing Plan with a pre-authorized check drawn on their checking
accounts. Under this plan, the shareholder may elect to have a specified amount
invested monthly or quarterly in Class A Shares. The amount specified by the
shareholder will be withdrawn from the shareholder's checking account using the
pre-authorized check and will be invested in Class A Shares at the applicable
Offering Price determined on the date the amount is available for investment.
Participation in the Automatic Investing Plan may be discontinued either by the
Fund or the shareholder upon 30 days' prior written notice to the other party.
A shareholder who wishes to enroll in the Automatic Investing Plan or who
wishes to obtain additional purchase information may do so by completing the
appropriate section of the Application Form attached to this Prospectus.

Purchases Through Dividend Reinvestment

      Unless the shareholder elects otherwise, all income dividends (consisting
of dividend and interest income and the excess, if any, of net short-term
capital gains over net long-term capital losses) and net capital gains
distributions, if any, will be reinvested in additional Class A Shares at net
asset value without a sales charge. However, shareholders may elect to
terminate automatic reinvestment by giving written notice to the Transfer Agent
at the address listed on the inside back cover of this Prospectus, either
directly or through their Participating Dealer or Shareholder Servicing Agent,
at least five days before the next date on which dividends or distributions
will be paid.
    
      Alternatively, shareholders may have their distributions invested in
shares of other funds in the Flag Investors family of funds. Shareholders who
are interested in this option should call (800) 553-8080 for additional
information.

<PAGE>

HOW TO REDEEM SHARES
- --------------------------------------------------------------------------------
   
      Shareholders may redeem all or part of their investment on any Business
Day by transmitting a redemption order through the Distributor, a Participating
Dealer, a Shareholder Servicing Agent or by regular or express mail to the
Fund's transfer agent (the "Transfer Agent") at its address listed on the back
inside cover to this Prospectus. Shareholders may also redeem Shares by
telephone (in amounts up to $50,000). (See "Telephone Transactions" below.) A
redemption order is effected at the net asset value per share (reduced by any
applicable contingent deferred sales charge) next determined after receipt of
the order (or, if stock certificates have been issued for the Class A Shares to
be redeemed, after the tender of the stock certificates for redemption).
Redemption orders received after 4:00 p.m. (Eastern Time) or the close of the
New York Stock Exchange, whichever is earlier, will be effected at the net
asset value next determined on the following Business Day. Payment for redeemed
Class A Shares will be made by check and will be mailed within seven days after
receipt of a duly authorized telephone redemption request or of a redemption
order fully completed and, as applicable, accompanied by the following
documents:

1) A letter of instructions, specifying the shareholder's account number with a
   Participating Dealer, if applicable, and the number of Class A Shares or
   dollar amount to be redeemed, signed by all owners of the Class A Shares
   in the exact names in which their account is maintained;

2) For redemptions in excess of $50,000, a guarantee of the signature of each
   registered owner by a member of the Federal Deposit Insurance Corporation,
   a trust company, broker, dealer, credit union (if authorized under state
   law), securities exchange or association, clearing agency, or savings
   association;

3) If Class A Shares are held in certificate form, stock certificates either
   properly endorsed or accompanied by a duly executed stock power for Class
   A Shares to be redeemed; and
    

8
- --------------------------------------------------------------------------------
<PAGE>

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

4) Any additional documents required for redemption by corporations,
   partnerships, trusts or fiduciaries.
   
      Dividends payable up to the date of the redemption of Class A Shares will
be paid on the next dividend payable date. If all of the Class A Shares in a
shareholder's account have been redeemed on a dividend payable date, the
dividend will be remitted by check to the shareholder.

      The Fund has the power under its Articles of Incorporation to redeem
shareholder accounts amounting to less than $500 (as a result of redemptions)
upon 60 days' written notice.

Systematic Withdrawal Plan

      Shareholders who hold Class A Shares having a value of $10,000 or more
may arrange to have a portion of their Shares redeemed monthly or quarterly
under the Fund's Systematic Withdrawal Plan. Such payments are drawn from
income dividends, and to the extent necessary, from Class A Share redemptions
(which would be a return of principal and, if reflecting a gain, would be
taxable). If redemptions continue, a shareholder's account may eventually be
exhausted. Because Class A Share purchases include a sales charge that will not
be recovered at the time of redemption, a shareholder should not have a
withdrawal plan in effect at the same time he is making recurring purchases of
Class A Shares. A shareholder who wishes to enroll in the Systematic Withdrawal
Plan may do so by completing the appropriate section of the Application Form
attached to this Prospectus.
    
 
TELEPHONE TRANSACTIONS
- --------------------------------------------------------------------------------
   
      Shareholders may exercise the exchange privilege with respect to other
Flag Investors funds, or redeem Class A Shares in amounts up to $50,000, by
notifying the Transfer Agent by telephone on any Business Day between the hours
of 8:30 a.m. and 5:30 p.m. (Eastern Time) or by regular or express mail at its
address listed on the back inside cover of this Prospectus. Telephone
transaction privileges are automatic. Shareholders may specifically request
that no telephone redemptions or exchanges be accepted for their accounts. This
election may be made on the Application Form or at any time thereafter by
completing and returning appropriate documentation supplied by the Transfer
Agent.
    
      A telephone exchange or redemption placed by 4:00 p.m. (Eastern Time) or
the close of the New York Stock Exchange, whichever is earlier, is effective
that day. Telephone orders placed after 4:00 p.m. (Eastern Time) will be
effected at the net asset value (less any applicable contingent deferred sales
charge on redemptions) as determined on the next Business Day.
   
      The Fund and the Transfer Agent will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. These
procedures include requiring the investor to provide certain personal
identification information at the time an account is opened and prior to
effecting each transaction requested by telephone. In addition, all telephone
transaction requests will be recorded and investors may be required to provide
additional telecopied instructions of such transaction requests. If these
procedures are employed, neither the Fund nor the Transfer Agent will be
responsible for any loss, liability, cost or expense for following instructions
received by telephone that either of them reasonably believes to be genuine.
During periods of extreme economic or market changes, shareholders may
experience difficulty in effecting telephone transactions. In such event,
requests should be made by regular or express mail. Class A Shares held in
certificate form may not be redeemed by telephone. (See "How to Invest in the
Fund -- Purchases by Exchange" and "How to Redeem Shares.")
    
DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------
Dividends and Distributions

      The Fund's policy is to distribute to shareholders substantially all of
its taxable net investment income (including net short-term capital gains) in
the form of monthly dividends. The Fund may distribute to shareholders any net
capital gains (net long-term capital gains less net short-term capital losses)
on an annual basis or, alternatively, may elect to retain net capital gains and
pay tax thereon.

                                                                               9
- --------------------------------------------------------------------------------
<PAGE>


- --------------------------------------------------------------------------------
   
Tax Treatment of Dividends and Distributions

      The following summary of certain federal income tax consequences is based
on current tax laws and regulations, which may be changed by legislative,
judicial or administrative action. No attempt has been made to present a
detailed explanation of the federal, state or local income tax treatment of the
Fund or the shareholders, and the discussion here is not intended as a
substitute for careful tax planning. Accordingly, shareholders are advised to
consult their tax advisors regarding specific questions as to federal, state
and local income taxes.

      The Statement of Additional Information sets forth further information
concerning taxes.

      The Fund intends to continue to qualify as a "regulated investment
company" under the Code and to distribute to its investors all of its net
investment income (including its net tax-exempt income) and net short-term and
long-term capital gain income, if any, so that it is not required to pay
federal income taxes on amounts so distributed. In addition, the Fund expects
to make sufficient distributions prior to the end of each calendar year to
avoid liability for federal excise tax. Shareholders will be advised at least
annually as to the federal income tax consequences of distributions made during
the year.
    
      Dividends derived from the Fund's net exempt-interest income and
designated by the Fund as exempt-interest dividends may be treated by the Fund's
shareholders as items of interest excludable from their gross income for federal
income tax purposes if the Fund qualifies as a regulated investment company and
if, at the close of each quarter of the Fund's taxable year, at least 50% of the
value of its total assets consists of securities the interest on which is
excluded from gross income. Although exempt-interest dividends are excludable
from a shareholder's gross income for regular income tax purposes, they may have
collateral federal income tax consequences, including alternative minimum tax
consequences. (See the Statement of Additional Information.)
   
      Current federal tax law limits the types and volume of bonds qualifying
for the federal income tax exemption of interest, which may have an effect on
the ability of the Fund to purchase sufficient amounts of tax-exempt securities
to satisfy the Code's requirements for the payment of exempt-interest
dividends. All or a portion of the interest on indebtedness incurred or
continued by a shareholder to purchase or carry Class A Shares may not be
deductible for federal income tax purposes. Furthermore, entities or persons
who are "substantial users" (or persons related to "substantial users") of
facilities financed by "private activity bonds" or "industrial development
bonds" should consult their tax advisors before purchasing Class A Shares. (See
the Statement of Additional Information.)
    

<PAGE>

      Under the Code, dividends attributable to interest on certain "private
activity bonds" issued after August 7, 1986, will be included in alternative
minimum taxable income for the purpose of determining liability (if any) for
the alternative minimum tax for individuals and for corporations. Additionally,
in the case of corporations, all tax-exempt interest dividends will be taken
into account in determining "adjusted current earnings" (as defined for federal
income tax purposes) for purposes of computing the alternative minimum tax
imposed on corporations.
   
      To the extent, if any, that dividends paid to investors are derived from
taxable income, such dividends will be subject to federal income tax. If the
Fund purchases a municipal security at a market discount, any gain realized by
the Fund upon sale or redemption of the municipal obligation shall be treated
as taxable interest income to the extent such gain does not exceed the market
discount and any gain realized in excess of the market discount will be treated
as capital gain. Distributions of net investment income and/or the excess, if
any, of net short-term capital gains over net long-term capital losses are
taxable to investors as ordinary income, regardless of whether such
distributions are paid in cash or reinvested in additional Class A Shares.
Distributions of net capital gains (the excess of net long-term capital gains
over net short-term capital losses) that are designated by the Fund as capital
gain dividends are taxable to investors as long-term capital gains, regardless
of the length of time the investor owned the Class A Shares. Since
substantially all of the net investment income of the Fund is expected to be
derived from earned interest, it is anticipated that no part of the Fund's
distributions will be eligible for the corporate dividends-received deduction.

      Ordinarily, shareholders will include all dividends declared by the Fund
as income in the year of payment. However, dividends declared payable to
shareholders of record in December of one year, but paid in January of the
following year, will be deemed for tax purposes to have been received by the
shareholders and paid by the Fund in the year in which the dividends were
declared. The Fund intends to make sufficient distributions of its ordinary
income and capital gain net income prior to the end of each calendar year to
avoid liability for federal excise tax.

      The sale, exchange or redemption of Class A Shares is a taxable event for
the shareholder.
    
Maryland Tax Disclosure

      To the extent the Fund qualifies as a regulated investment company under
the Code, it will be subject


10
- --------------------------------------------------------------------------------
<PAGE>


- --------------------------------------------------------------------------------
   
to tax only on (1) that portion of its income on which tax is imposed for
federal income tax purposes under Section 852(b)(1) of the Code and (2) that
portion of its income that consists of federally tax-exempt interest on
obligations other than Maryland Exempt Obligations (hereinafter defined) to the
extent such interest is not paid to Fund shareholders in the form of exempt-
interest dividends. To the extent dividends paid by the Fund represent interest
excludable from gross income for federal income tax purposes, that portion of
exempt-interest dividends that represents interest received by the Fund on
obligations issued by the State of Maryland, its political subdivisions, Puerto
Rico, the U.S. Virgin Islands, or Guam and their respective authorities or
municipalities ("Maryland Exempt Obligations"), will be exempt from Maryland
state and local income taxes when allocated or distributed to a shareholder of
the Fund except in the case of a shareholder that is a financial institution.
Except as noted below, all other dividend distributions will be subject to
Maryland state and local income taxes.
    
   
      Capital gains distributed by the Fund to a shareholder or any gains
realized by a shareholder from a redemption or sale of shares must be
recognized for Maryland state and local income tax purposes to the extent
recognized for federal income tax purposes. However, capital gains
distributions included in the gross income of shareholders for federal income
tax purposes are subtracted from capital gains income for Maryland income tax
purposes to the extent such distributions are derived from the disposition of
debt obligations issued by the State of Maryland, its political subdivisions
and authorities.

      Dividends received by a shareholder from the Fund that are derived from
interest on U.S. government obligations will be exempt from Maryland state and
local incomes taxes. Entities subject to the financial institution franchise
tax will generally be subject to tax on distributions from the Fund.

      In the case of individuals, Maryland presently imposes an income tax on
items of tax preference with reference to such items as defined in the Code for
purposes of calculating the federal alternative minimum tax. Interest paid on
certain private activity bonds of an issuer other than the State of Maryland,
its political subdivisions or authorities is a preference item taken into
account for this purpose. Accordingly, if the Fund holds such bonds, the excess
of 50% of that portion of exempt interest dividends that is attributable to
interest on such bonds over a threshold amount may be taxable by Maryland.
Interest on indebtedness incurred or continued (directly or indirectly) by a
shareholder in order to purchase or carry shares of the Fund will not be
deductible for Maryland state and local income tax purposes. Individuals will
not be subject to personal property tax on their shares of the Fund. Shares of
the Fund held by a Maryland resident at death may be subject to Maryland
inheritance and estate taxes.
    
 
MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------
   
      The overall business affairs of the Fund are managed by its Board of
Directors. The Board approves all significant agreements between the Fund and
persons or companies furnishing services to the Fund, including the Fund's
agreements with its investment advisor, distributor, custodian and transfer
agent. A majority of the Directors of the Fund have no affiliation with the
Distributor or the Advisor.
 
    

<PAGE>

INVESTMENT ADVISOR
- --------------------------------------------------------------------------------
   
      Investment Company Capital Corp. ("ICC" or the "Advisor"), the Fund's
investment advisor, is an indirect subsidiary of Bankers Trust New York
Corporation. ICC is also the investment advisor to other mutual funds in the
Flag Investors family of funds and BT Alex. Brown Cash Reserve Fund, Inc.,
which funds had approximately $5.5 billion of net assets as of May 31, 1997.

      ICC is responsible for the general management of the Fund, as well as for
decisions to buy and sell securities for the Fund, for broker-dealer selection,
and for negotiation of commission rates under standards established and
periodically reviewed by the Board of Directors. ICC currently intends to
waive, on a voluntary basis, its annual fee to the extent necessary so that the
Fund's annual expenses do not exceed 0.70% of the Fund's average daily net
assets. For the fiscal year ended March 31, 1997, ICC waived all advisory fees,
amounting to $79,698, and reimbursed expenses of $64,880.

      ICC also serves as the Fund's transfer and dividend disbursing agent and
provides accounting services to the Fund. (See "Custodian, Transfer Agent and
Accounting Services.")

Portfolio Managers
   
      Messrs. M. Elliott Randolph, Jr. and Paul D. Corbin have shared primary
responsibility for managing the Fund's assets since inception.

      M. Elliott Randolph, Jr. has 23 years of investment experience and has
been a portfolio manager with the Advisor since 1991. From 1988-1991 he was a
Principal with Monument Capital Management, Inc.

      Paul D. Corbin has over 18 years of investment experience and has been a
portfolio manager with the Advisor since 1991. From 1984-1991 he served as the
Senior Vice President in charge of Fixed Income Portfolio Management at First
National Bank of Maryland.
    
 
DISTRIBUTOR
- --------------------------------------------------------------------------------
   
      Effective September 1, 1997, ICC Distributors, Inc. ("ICC Distributors"
or the "Distributor") acts as distributor for each class of the Fund's shares.
Prior to September 1, 1997, Alex Brown & Sons Incorporated served as
distributor for each class of the Fund's shares for the same compensation and
on substantially the same terms and conditions as ICC Distributors. ICC
Distributors is a registered broker-dealer that offers distribution services to
a variety of registered investment companies including the other funds in the
Flag Investors family of funds and BT Alex. Brown Cash Reserve Fund, Inc. ICC
Distributors is not affiliated with the Advisor.

The Fund has adopted a Distribution Agreement and related Plan of Distribution
(the "Plan") pursuant to Rule 12b-1 under the 1940 Act. As compensation for
providing distribution services for the Class A Shares ICC Distributors
receives a fee from the Fund that represents .25% of the Shares' average daily
net assets.

ICC Distributors expects to allocate most of its fee to Participating Dealers as
compensation for their ongoing shareholder services, including processing
purchase and sale requests and responding to shareholder inquiries.

In addition, the Fund may enter into agreements with certain financial
institutions, such as banks and BT Alex. Brown Incorporated, to provide
shareholder services pursuant to which ICC Distributors will allocate up to all
of its distribution fee as compensation for such services. Such financial
institutions may impose separate fees in connection with these services and
investors should review this Prospectus in conjunction with any such
institution's fee schedule.

Payments under the Plan are made as described above regardless of ICC
Distributors' actual cost of providing distribution services and may be used to
pay ICC Distributors' overhead expenses. If the cost of providing distribution
services to the Fund in connection with the sale of the Class A Shares is less
than the payments received the unexpended portion may be retained by ICC
Distributors. ICC Distributors will from time to time and from its own
resources pay or allow additional discounts or promotional incentives in the
form of cash or other compensation (including merchandise or travel) to
Participating Dealers.
 
    
CUSTODIAN, TRANSFER AGENT AND ACCOUNTING SERVICES
- --------------------------------------------------------------------------------
   
      Investment Company Capital Corp. is the Fund's transfer and dividend
disbursing agent. ICC also provides accounting services to the Fund. As
compensation for providing accounting services to the Fund for the fiscal year
ended March 31, 1997, ICC received a fee equal to 0.11% of the Fund's average
daily net assets. (See the Statement of Additional Information.)
PNC Bank, National Association acts as custodian of the Fund's assets. The
Fund's Board of Directors has approved Bankers Trust Company, a subsidiary of
Bankers Trust New York Corporation and an affiliate of the Fund, as custodian.
Currently, it is anticipated that Bankers Trust Company will provide custodial
services to the Fund effective September 22, 1997.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
   
      From time to time the Fund may advertise its performance including
comparisons to other mutual funds with similar investment objectives and to
relevant indices. Any quotations of yield of the Fund will be determined by
dividing the net investment income earned by the Fund during a 30-day period by
the maximum offering price per Share on the last day of the period and
annualizing the result on a semi-annual basis. The Fund may also advertise a
"tax-equivalent yield," which is calculated by determining the rate of return
that would have to be achieved on a fully taxable investment to produce the
after-tax equivalent of the Fund's yield, assuming certain tax brackets for a
shareholder. All advertisements of performance will show the average annual
total return net of the Fund's maximum sales charge, over one-, five- and
ten-year periods or, if such periods have not yet elapsed, shorter periods
corresponding to the life of the Fund. Such total return quotations will be
computed by finding average annual compounded rates of return over such periods
that would equate an assumed initial investment of $1,000 to the ending
redeemable value, net of the maximum sales charge and other fees according to
the required standardized calculation. The standardized calculation is required
by the SEC to provide consistency and comparability in investment company
advertising and is not equivalent to a yield calculation.
    
      If the Fund compares its performance to other funds or to relevant
indices, the Fund's performance will be stated in the same terms in which such
comparative data and indices are stated, which is normally total return rather
than yield. For these purposes, the performance of the Fund, as well as the
performance of such investment companies or indices, may not reflect sales
charges, which, if reflected, would reduce performance results.
   
      The performance of the Fund may be compared to data prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. and Morningstar
Inc., independent services that monitor the performance of mutual funds. The
Fund may also use total return performance data as reported in national
financial and industry publications that monitor the performance of mutual
funds such as Money Magazine, Forbes, Business Week, Barron's, Investor's
Daily, IBC/Donoghue's Money Fund Report and The Wall Street Journal.

      Performance will fluctuate and any statement of performance should not be
considered as representative of the future performance of the Fund.
Shareholders should remember that performance is generally a function of the
type and quality of instruments held by the Fund, operating expenses and market
conditions. Any fees charged by financial institutions with respect to customer
accounts through which Shares may be purchased, although not included in
calculations of performance, will reduce performance results.
    
 
GENERAL INFORMATION
- --------------------------------------------------------------------------------
Description of Shares
   
      The Fund is an open-end, non-diversified management investment company
organized under the laws of the State of Maryland on July 23, 1993 and is
authorized to issue 40 million shares of capital stock, par value of $.001 per
share, all of which shares are designated common stock. Each share has one vote
and shall be entitled to dividends and distributions when and if declared by
the Fund. In the event of liquidation or dissolution of the Fund, each share
would be entitled to its pro rata portion of the Fund's assets after all debts
and expenses have been paid. The fiscal year-end of the Fund is March 31.
    
      The Board of Directors may classify any authorized but unissued Shares
into classes and may establish certain distinctions between classes relating to
additional voting rights, payments of dividends, rights upon liquidation or
distribution of the assets of the Fund and any other restrictions permitted by
law and the Fund's charter.
   
      The Board of Directors is authorized to establish additional series of
shares of capital stock, each of which would evidence interests in a separate
portfolio or securities, and separate classes of each series of the Fund. The
shares offered by this Prospectus have been designated "Flag Investors Maryland
Intermediate Tax-Free Income Fund Class A Shares." The Board has no present
intention of establishing any additional series of the Fund but the Fund does
have two other classes of shares in addition to the shares offered hereby:
"Flag Investors Maryland Intermediate Tax-Free Income Fund Institutional
Shares" and "Alex. Brown
    

                                                                              13
- --------------------------------------------------------------------------------
<PAGE>


- --------------------------------------------------------------------------------
   
Capital Advisory & Trust Maryland Intermediate Tax-Free Income Shares."
Additional information concerning the Fund's other classes may be obtained by
calling the Fund at (800) 767-FLAG. Different classes of the Fund may be
offered to certain investors and holders of such shares may be entitled to
certain exchange privileges not offered to Shares. All classes of the Fund
share a common investment objective, portfolio of investments and advisory fee,
but the classes may have different sales load structures, distribution fees or
other expenses and, accordingly, the net asset value per share of classes may
differ at times.

Annual Meetings

      Unless required under applicable Maryland law, the Fund does not expect
to hold annual meetings of shareholders. However, shareholders of the Fund
retain the right, under certain circumstances, to request that a meeting of
shareholders be held for the purpose of considering the removal of a Director
from office, and if such a request is made, the Fund will assist with the
shareholder communications in connection with the meeting.

Reports

The Fund furnishes shareholders with semi-annual reports containing information
about the Fund and its operations, including a list of investments held in the
Fund's portfolio and financial statements. The annual financial statements are
audited by the Fund's independent auditors, Deloitte & Touche LLP.

Shareholder Inquiries
      Shareholders with inquiries concerning their Shares should contact the
Fund at (800)767-FLAG, the Transfer Agent at (800)553-8080 or any Participating
Dealer or Shareholder Servicing Agent, as appropriate.

                      Signature and Taxpayer Certification

 The Fund may be required to withhold and remit to the U.S. Treasury 31% of any
 taxable dividends, capital gains distributions and redemption proceeds paid to
 any individual or certain other non-corporate shareholders who fail to provide
 the information and/or certifications required below. This backup withholding
 is not an additional tax, and any amounts withheld may be credited against the
 shareholder's ultimate U.S. tax liability.

 By signing this Application, I hereby certify under penalties of perjury that
 the information on this Application is complete and correct and that as
 required by federal law: (Please check applicable boxes)
 [ ] U.S. Citizen/Taxpayer:
     [ ] I certify that (1) the number shown above on this form is the correct
         Social Security Number or Tax ID Number and (2) I am not subject to any
         backup withholding either because (a) I am exempt from backup
         withholding, or (b) I have not been notified by the Internal Revenue
         Service ("IRS") 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.
     [ ] If no Tax ID Number or Social Security Number has been provided above,
         I have applied, or intend to apply, to the IRS or the Social Security
         Administration for a Tax ID Number or a Social Security Number, and I
         understand that if I do not provide either number to the Transfer Agent
         within 60 days of the date of this Application or if I fail to furnish
         my correct Social Security Number or Tax ID Number, I may be subject to
         a penalty and a 31% backup withholding on distributions and redemption
         proceeds. (Please provide either number on IRS Form W-9. You may
         request such form by calling the Transfer Agent at 800-553-8080).
 [ ] Non-U.S. Citizen/Taxpayer:
     Indicated country of residence for tax purposes:__________________________
     Under penalties of perjury, I certify that I am not a U.S. citizen or
resident and I am an exempt foreign person as defined by the Internal Revenue
Service.

I have received a copy of the Fund's prospectus. I acknowledge that the
telephone redemption and exchange privileges are automatic and will be effected
as described in the Fund's current prospectus (see "Telephone Transactions"). I
also acknowledge that I may bear the risk of loss in the event of fraudulent
use of such privileges. If I do not want telephone redemption or exchange
privileges, I have so indicated on this Application.

 The Internal Revenue Service does not require your consent to any provision of
 this document other than the certifications required to avoid backup 
 withholding.

INVESTMENT PROGRAM
- --------------------------------------------------------------------------------
Investment Objective, Policies and Risk
Considerations

      The Fund seeks to provide current income exempt from federal income taxes
and Maryland state and local income taxes consistent with preservation of
principal within an intermediate-term maturity structure. There is no assurance
this objective will be met.

   
      Under normal conditions, the Fund expects to be as fully invested as
practicable in obligations that, in the opinion of bond counsel to the issuers,
produce interest exempt from federal income tax and Maryland state and local
income tax and at least 65% of the Fund's total assets will be invested in
securities of Maryland issuers. These include municipal obligations issued by
the State of Maryland and its political subdivisions, agencies or
instrumentalities. The Fund may invest up to 35% of its assets in obligations
of other issuers of securities the interest on which is exempt from Maryland
state and local taxes. These issuers would include territories or possessions
of the United States. However, the Fund has no present intention to invest in
securities issued by such territories or possessions.

      As a matter of fundamental policy, under normal conditions, the Fund will
invest at least 80% of its total assets in securities the interest on which is
exempt from federal and Maryland state and local income taxes and 80% of the
Fund's assets will be invested in municipal securities the income from which is
not subject to the alternative minimum tax. Income derived from securities
subject to the alternative minimum tax is not included when computing income
exempt from federal and Maryland state and local income taxes. Under normal
conditions, the Fund may invest up to 20% of its net assets in municipal
securities, the income from which is not exempt from Maryland state and local
income taxes. For temporary, defensive purposes when, in the opinion of the
Fund's investment advisor (the "Advisor"), securities exempt from Maryland
state and local income tax are not readily available or of sufficient quality,
the Fund can invest up to 100% of its assets in securities that pay interest
that is exempt only from federal income taxes or in taxable U.S. Treasury
securities.

      The Fund is a non-diversified investment company, which means that more
than 5% of its assets may be invested in each of one or more issuers. Since a
relatively high percentage of assets of the Fund may be invested in the
obligations of a limited number of issuers, the value of shares of the Fund may
be more susceptible to any single economic, political or regulatory occurrence
than the shares of a diversified investment company would be. The Fund intends
to satisfy the diversification requirements necessary to qualify as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code").
    

      The Fund currently contemplates that it will not invest more than 25% of
its total assets (at market value at the time of purchase) in municipal
securities, the interest on which is paid from revenues of projects with
similar characteristics. See also "Special Considerations Relating To Maryland
Municipal Securities."

      Under normal circumstances the Fund's portfolio will have a dollar
weighted average maturity of between 3 and 10 years. The value of obligations
purchased by the Fund will change as interest rates change. Thus, a decrease in
interest rates generally will result in an increase in the value of shares of
the Fund. Conversely, an increase in interest rates will generally result in a
decrease in the value of the shares of the Fund. The magnitude of these
fluctuations will be greater as the average maturity of the Fund increases.

<PAGE>

   
      Municipal notes in which the Fund may invest will be limited to those
obligations (i) that are rated MIG-1 or VMIG-1 at the time of investment by
Moody's Investors Service, Inc. ("Moody's"), (ii) that are rated SP-1 at the
time of investment by Standard & Poor's Ratings Group ("S&P"), or (iii) that,
if not rated by S&P or Moody's, are of comparable quality in the Advisor's
judgment. Municipal bonds in which the Fund may invest must be rated BBB or
better by S&P or Baa or better by Moody's at the time of investment or, if
unrated by S&P or Moody's must be of comparable quality in the Advisor's
judgment. Securities rated Baa or BBB are deemed to have speculative
characteristics. Tax-exempt commercial paper will be limited to investments in
obligations that are rated at least A-1 by S&P or Prime-1 by Moody's at the
time of investment or, if unrated by S&P or Moody's, are of comparable quality
in the Advisor's judgment. These ratings may be based in part on credit support
provided by a bank or other entity. Accordingly, a decline in the
creditworthiness of the entity providing such support could affect the rating
of the security, as well as the payment of interest and principal. For a
description of the above ratings, see the Appendix to the Statement of
Additional Information.
    

      The Fund may also enter into futures contracts and options on futures
contracts, although it has no present intention to do so. Gains recognized by
the Fund from such transactions would constitute taxable income to
shareholders.

      The Fund may also purchase variable and floating rate demand notes and
bonds. The Advisor will invest


4
- --------------------------------------------------------------------------------
<PAGE>

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

in commitments to purchase securities on a "when-issued" basis and reserves the
right to engage in "put" transactions on a daily, weekly or monthly basis.

Municipal Securities

      Municipal securities that the Fund may purchase consist of (i) debt
obligations issued by or on behalf of public authorities to obtain funds to be
used for various public facilities, for refunding outstanding obligations, for
general operating expenses and for lending such funds to other public
institutions and facilities, and (ii) certain private activity and industrial
development bonds issued by or on behalf of public authorities to obtain funds
to provide for the construction, equipment, repair or improvement of privately
operated facilities. Municipal notes include general obligation notes, tax
anticipation notes, revenue anticipation notes, bond anticipation notes,
certificates of indebtedness, demand notes, construction loan notes and
participation interests therein. Municipal bonds include general obligation
bonds, revenue or special obligation bonds, private activity bonds, industrial
development bonds and participation interests therein. General obligation bonds
are backed by the taxing power of the issuing municipality. Revenue bonds are
backed by the revenues of a project or facility, tolls from a toll bridge, or
lease payments, for example. The payment of principal and interest on private
activity and industrial development bonds generally is dependent solely on the
ability of the facility's user to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment.
   
      The Fund may purchase municipal lease obligations, including certificates
of participation ("COPs") in municipal leases. The Fund may acquire municipal
lease obligations that may be assigned by the lessee to another party provided
the obligation continues to provide tax-exempt interest. The Fund will not
purchase municipal lease obligations to the extent it holds municipal lease
obligations and illiquid securities in an amount exceeding 10% of its net
assets unless the Advisor determines that the municipal lease obligations are
liquid pursuant to guidelines established by the Board of Directors of the
Fund. Pursuant to these guidelines, the Advisor, in making this liquidity
determination, will consider, among other factors, the strength and nature of
the secondary market for such obligations, the prospect for its future
marketability and whether such obligations are rated. The Fund expects that it
will purchase only rated municipal lease obligations. In addition, the Fund may
purchase COPs representing interests in other municipal securities (such as
industrial development bonds). (See "Participation Interests.")

      Municipal obligations purchased by the Fund that fall below the above
rating criteria after the purchase by the Fund shall be sold as promptly as
possible consistent with ordinary disposition.
    
Insured Obligations

      The Fund may invest in obligations that are insured as to the scheduled
payment of all installments of principal and interest as they fall due. The
purpose of this insurance is to minimize credit risks to the Fund and its
shareholders associated with defaults in Maryland municipal obligations owned
by the Fund. This insurance does not insure against market risk and therefore
does not guarantee the market value of the obligations in the Fund's investment
portfolio upon which the net asset value of the Fund's shares is based. The
market value will continue to fluctuate in response to fluctuations in interest
rates or the bond market. Similarly, this insurance does not cover or guarantee
the value of the shares of the Fund. The ratings of the insured obligations may
be based in part on insurance provided by an insurance company. Accordingly, a
decline in the creditworthiness of the insurance company providing the
insurance could affect the rating of the security, as well as the payment of
interest and principal.

Participation Interests
   
      The Fund may invest in COPs representing participation interests in
municipal securities (such as AMT-Subject Bonds). A participation interest (i)
may pay a fixed, floating or variable rate of interest; (ii) gives the
purchaser an undivided interest in the municipal securities in the proportion
that the Fund's participation interest bears to the total principal amount of
the municipal securities; and (iii) provides a demand repurchase feature. Each
participation is backed by an irrevocable letter of credit or guarantee of a
bank that meets the prescribed quality standards of the Fund. The Fund has the
right to sell the instrument back to the issuing bank or draw on the letter of
credit on demand for all or any part of the Fund's participation interest in
the municipal security, plus accrued interest. Banks will retain or receive a
service fee, letter of credit fee and a fee for issuing repurchase commitments
in an amount equal to the excess of the interest paid on the municipal
securities over the negotiated yield at which the instruments were purchased by
the Fund. Participation interests in the form to be purchased by the Fund are
new instruments, and no ruling of the Internal Revenue Service has been secured
relating to their tax-exempt status. The Fund intends to purchase participation
interests based upon opinions of counsel to the issuer to the effect that
    

                                                                               5
- --------------------------------------------------------------------------------
<PAGE>

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

income from the participation interests is tax-exempt to the Fund. For purposes
of complying with diversification requirements, the Fund will treat both the
trust, or similar entity established to issue COPs, and the issuers of the
underlying municipal securities as issuers. Also, the Fund will limit its
investments in COPs to less than 25% of its total assets.
    

Repurchase Agreements
   
      The Fund may agree to purchase U.S. Treasury securities from creditworthy
financial institutions, such as banks and broker-dealers, subject to the
seller's agreement to repurchase the securities at an established time and
price. Default by or bankruptcy proceedings with respect to the seller may,
however, expose the Fund to possible loss because of adverse market action or
delay in connection with the disposition of the underlying obligations.
    

Variable and Floating Rate Demand
Obligations
   
      The Fund may purchase variable and floating rate demand notes and bonds,
which are tax-exempt obligations normally having stated maturities in excess of
one year, but which permit the holder to demand payment of principal either at
any time or at specified intervals. The interest rates on these obligations
fluctuate from time to time in response to changes in the market interest
rates. Frequently, such obligations are secured by letters of credit or other
credit support arrangements provided by banks. Where these obligations are not
secured by letters of credit or other credit support arrangements, the Fund's
right to redeem will be dependent on the ability of the borrower to pay
principal and interest on demand. Each demand note and bond purchased by the
Fund will meet the quality criteria established for the purchase of other
municipal obligations. The Fund will not invest more than 10% of its net assets
in floating or variable rate demand obligations as to which the Fund cannot
exercise the demand feature on less than seven days' notice if there is no
secondary market available for these obligations.
    

When-Issued Securities

      When-issued securities are securities purchased for delivery beyond the
normal settlement date at a stated price and yield. The Fund will generally not
pay for such securities or start earning interest on them until they are
received. When-issued commitments will not be used for speculative purposes and
will be entered into only with the intention of actually acquiring the
securities. The securities so purchased or sold are subject to market
fluctuation so, at the time of delivery of the securities, their value may be
more or less than the purchase or sale price. The Fund will ordinarily invest
no more than 40% of its net assets at any time in municipal obligations
purchased on a when-issued basis.

Special Considerations Relating to Maryland
Municipal Securities
   
      The Fund's concentration in securities issued by the State of Maryland
and its political subdivisions, agencies and instrumentalities involves greater
risk than a fund broadly invested across many states and municipalities. In
particular, changes in economic conditions and governmental policies of the
State of Maryland and its municipalities could adversely affect the value of
the Fund and the securities held by it. For a further description of these
risks, see "Risk Factors Associated with a Maryland Portfolio" in the Statement
of Additional Information.
    

<PAGE>
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
   
      The Fund's investment program is subject to a number of restrictions that
reflect both self-imposed standards and federal regulatory limitations.

1) As a matter of fundamental policy, the Fund will not concentrate 25% or more
   of its total assets in securities of issuers in any one industry, provided
   that this limitation does not apply to investments in tax-exempt securities
   issued by governments or political subdivisions of governments (for these
   purposes the U.S. Government and its agencies and instrumentalities are not
   considered an issuer). This restriction may not be changed without
   shareholder approval;


2) Additionally, the Fund will not invest more than 10% of the Fund's net assets
   in illiquid securities, including repurchase agreements with maturities of
   greater than seven days. This restriction may be changed by a vote of the
   Board of Directors.


      The Fund is subject to further investment restrictions that are set forth
in the Statement of Additional Information.

HOW TO INVEST IN INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------
   
      Institutions (e.g., banks and trust companies, savings institutions,
corporations, insurance companies, investment counselors, pension funds,
employee benefit plans, trusts, estates and educational, religious and
charitable institutions) and clients of investment advisory affiliates of BT
Alex. Brown Incorporated ("BT Alex. Brown") may purchase Institutional Shares
through any securities dealer that is authorized to distribute Institutional
Shares ("Participating Dealers") or by completing the Application Form attached
to this Prospectus and returning it, together with payment of the purchase
price, as instructed in the Application.

      The minimum initial investment in Institutional Shares is $500,000,
except that the minimum initial investment is $1,000,000 for qualified
retirement plans. There is no minimum for clients of investment advisory
affiliates of BT Alex. Brown or for subsequent investments. The Fund reserves
the right to suspend the sale of Institutional Shares at any time at the
discretion of the Distributor and the Advisor.

      Orders for purchases of Institutional Shares are accepted on any day on
which the New York Stock Exchange is open for business (a "Business Day").
Purchase orders for Institutional Shares will be executed at the net asset
value per share next determined after receipt of the purchase order. Purchases
made through the Distributor or a Participating Dealer must be in accordance
with such entity's payment procedures. The Distributor may, at its sole
discretion, refuse to accept any purchase order.

      The net asset value per share is determined daily as of the close of the
New York Stock Exchange, which is ordinarily 4:00 p.m. (Eastern Time), on each
Business Day. Net asset value per share of a class is calculated by valuing its
share of the Fund's assets, deducting all liabilities attributable to that
class, and dividing the resulting amount by the number of then outstanding
shares of the class. For this purpose, portfolio securities are given their
market value where feasible. Securities or other assets for which market
quotations are not readily available are valued at their fair value as
determined in good faith under procedures established from time to time and
monitored by the Fund's Board of Directors. Such procedures may include the use
of an independent pricing service, which uses prices based upon yields or
prices of securities of comparable quality, coupon, maturity and type;
indications as to values from dealers; and general market conditions. Debt
obligations with maturities of 60 days or less will be valued at amortized
cost, which constitutes fair value as determined by the Fund's Board of
Directors.
    
Other Information
   
      Periodic statements of account from the Fund will reflect all dividends,
purchases and redemptions of Institutional Shares.

      In the interest of economy and convenience and because of the operating
procedures for the Institutional Shares, certificates representing such shares
will not be issued. All purchases of Institutional Shares are confirmed and
credited to the shareholder's account on the Fund's books maintained by the
Fund's transfer agent (the "Transfer Agent") or its agents. Shareholders will
have the same rights and ownership with respect to such shares as if
certificates had been issued.
 
    

<PAGE>

HOW TO REDEEM INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------
   
      Shareholders may redeem all or part of their Institutional Shares on any
Business Day by transmitting a redemption order through a Participating Dealer,
or by regular or express mail to the Transfer Agent at its address listed on the
inside back cover of this Prospectus. Shareholders may also redeem Institutional
Shares by telephone (in amounts up to $500,000). (See "Telephone Transactions"
below.) A redemption request is effected at the net asset value per share next
determined after receipt of the order in proper form. Redemption orders received
after 4:00 p.m. (Eastern Time), or the close of the New York Stock Exchange,
whichever is earlier, will be effected at the next net asset value next
determined on the following Business Day. Payment for redeemed Institutional
Shares will be made by wire transfer of funds to the shareholder's bank, or to a
Participating Dealer, as appropriate, upon receipt of a duly authorized
redemption request as promptly as feasible and, under most circumstances, within
three Business Days.

      Dividends payable up to the date of the redemption of Institutional
Shares will be paid on the next dividend payment date. If all of the
Institutional Shares in an account have been redeemed on the dividend payment
date, the dividend will be remitted by wire to the shareholder's bank or to a
Participating Dealer, as appropriate.

      The Fund has the power, under its Articles of Incorporation, to redeem
shareholder accounts amounting to less than $500 upon 60 days' written notice.
    


                                                                               7

TELEPHONE TRANSACTIONS
- --------------------------------------------------------------------------------
   
      Shareholders may exercise the exchange privilege with respect to other
Flag Investors funds, or redeem Institutional Shares in amounts up to $500,000,
by notifying the Transfer Agent by telephone on any Business Day between the
hours of 8:30 a.m. and 5:30 p.m. (Eastern Time) or by regular or express mail
at its address listed on the inside back cover of this Prospectus. Telephone
transaction privileges are automatic. Shareholders may specifically request
that no telephone redemptions or exchanges be accepted for their accounts. This
election may be made on the Application Form or at any time thereafter by
completing and returning appropriate documentation supplied by the Transfer
Agent.

      A telephone exchange or redemption placed by 4:00 p.m. (Eastern Time) or
the close of the New York Stock Exchange, whichever is earlier, is effective
that day. Telephone orders placed after 4:00 p.m. (Eastern Time) will be
effected at the net asset value as next determined on the following Business
Day.
      The Fund and the Transfer Agent will employ reasonable procedures to
confirm that instructions communicated by telephone are genuine. These
procedures include requiring the investor to provide certain personal
identification information at the time an account is opened and prior to
effecting each transaction requested by telephone. In addition, all telephone
transaction requests will be recorded and investors may be required to provide
additional telecopied instructions of such transaction requests. If these
procedures are employed, neither the Fund nor the Transfer Agent will be
responsible for any loss, liability, cost or expense for following instructions
received by telephone that either of them reasonably believes to be genuine.
During periods of extreme economic or market changes, shareholders may
experience difficulty in effecting telephone transactions. In such event,
requests should be made by express mail or facsimile. (See "How to Invest in
Institutional Shares -- Purchases by Exchange" and "How to Redeem Institutional
Shares.")
    
 
DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------

Dividends and Distributions
      The Fund's policy is to distribute to shareholders substantially all of
its taxable net investment income (including net short-term capital gains) in
the form of monthly dividends. The Fund may distribute to shareholders any net
capital gains (net long-term capital gains less net short-term capital losses)
on an annual basis or, alternatively, may elect to retain net capital gains and
pay tax thereon.
   
      Unless the shareholder elects otherwise, all income dividends (consisting
of dividend and interest income and the excess, if any, of net short-term
capital gains over net long-term capital losses) and net capital gains
distributions, if any, will be reinvested in additional Institutional Shares at
net asset value. However, shareholders may elect to terminate automatic
reinvestment by giving written notice to the Transfer Agent (see "Custodian,
Transfer Agent and Accounting Services"), either directly or through the
Distributor or a Participating Dealer, at least five days before the next date
on which dividends or distributions will be paid.
    
Tax Treatment of Dividends and Distributions
   
      The following summary of certain federal income tax consequences is based
on current tax laws and regulations, which may be changed by legislative,
judicial or administrative action. No attempt has been made to present a
detailed explanation of the federal, state or local income tax treatment of the
Fund or the shareholders, and the discussion here is not intended as a
substitute for careful tax planning. Accordingly, shareholders are advised to
consult their tax advisors regarding specific questions as to federal, state
and local income taxes.

      The Statement of Additional Information sets forth further information
concerning taxes.

      The Fund intends to continue to qualify as a "regulated investment
company" under the Code and to distribute to its investors all of its net
investment income (including its net tax-exempt income) and net short-term and
long-term capital gain income, if any, so that it is not required to pay
federal income taxes on amounts so distributed. In addition, the Fund expects
to make sufficient distributions prior to the end of each calendar year to
avoid liability for federal excise tax. Shareholders will be advised at least
annually as to the federal income tax consequences of distributions made during
the year.
    
Dividends derived from the Fund's net exempt-interest income and designated by
the Fund as exempt-interest dividends may be treated by the Fund's shareholders
as items of interest excludable from their gross


8
- --------------------------------------------------------------------------------
<PAGE>

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

income for federal income tax purposes if the Fund qualifies as a regulated
investment company and if, at the close of each quarter of the Fund's taxable
year, at least 50% of the value of its total assets consists of securities the
interest on which is excluded from gross income. Although exempt-interest
dividends are excludable from a shareholder's gross income for regular income
tax purposes, they may have collateral federal income tax consequences,
including alternative minimum tax consequences. (See the Statement of
Additional Information.)
   
      Current federal tax law limits the types and volume of bonds qualifying
for the federal income tax exemption of interest, which may have an effect on
the ability of the Fund to purchase sufficient amounts of tax-exempt securities
to satisfy the Code's requirements for the payment of exempt-interest
dividends. All or a portion of the interest on indebtedness incurred or
continued by a shareholder to purchase or carry Institutional Shares may not be
deductible for federal income tax purposes. Furthermore, entities or persons
who are "substantial users" (or persons related to "substantial users") of
facilities financed by "private activity bonds" or "industrial development
bonds" should consult their tax advisors before purchasing Institutional
Shares.
    
      Under the Code, dividends attributable to interest on certain "private
activity bonds" issued after August 7, 1986, will be included in alternative
minimum taxable income for the purpose of determining liability (if any) for
the alternative minimum tax for individuals and for corporations. Additionally,
in the case of corporations, all tax-exempt interest dividends will be taken
into account in determining "adjusted current earnings" (as defined for federal
income tax purposes) for purposes of computing the alternative minimum tax
imposed on corporations.

      To the extent, if any, that dividends paid to investors are derived from
taxable income, such dividends will be subject to federal income tax. In
addition, as substantially all of the Fund's income is expected to be derived
from earned interest, it is anticipated that no portion of the Fund's
distributions will be eligible for the corporate dividends-received deduction.
If the Fund purchases a municipal security at a market discount, any gain
realized by the Fund upon sale or redemption of the municipal obligation shall
be treated as taxable interest income to the extent such gain does not exceed
the market discount and any gain realized in excess of the market discount will
be treated as capital gain. Distributions of net investment income and/or the
excess, if any, of net short-term capital gains over net long-term capital
losses are taxable to investors as ordinary income, regardless of whether such
distributions are paid in cash or reinvested in additional Institutional
Shares. Distributions of net capital gains (the excess of net long-term capital
gains over net short-term capital losses) that are designated by the Fund as
capital gain dividends are taxable to investors as long-term capital gains,
regardless of the length of time the investor owned the Institutional Shares.
   
      Ordinarily, shareholders will include all dividends declared by the Fund
as income in the year of payment. However, dividends declared payable to
shareholders of record in December of one year, but paid in January of the
following year, will be deemed for tax purposes to have been received by the
shareholders and paid by the Fund in the year in which the dividends were
declared.

      The Fund intends to make sufficient distributions of its ordinary income
and capital gain net income prior to the end of each calendar year to avoid
liability for federal excise tax.

      The sale, exchange or redemption of Institutional Shares is a taxable
event to the shareholder.

Maryland Tax Disclosure
   
      To the extent the Fund qualifies as a regulated investment company under
the Code, it will be subject to tax only on (1) that portion of its income on
which tax is imposed for federal income tax purposes under Section 852(b)(1) of
the Code and (2) that portion of its income that consists of federally
tax-exempt interest on obligations other than Maryland Exempt Obligations
(hereinafter defined) to the extent such interest is not paid to Fund
shareholders in the form of exempt-interest dividends. To the extent dividends
paid by the Fund represent interest excludable from gross income for federal
income tax purposes, that portion of exempt-interest dividends that represents
interest received by the Fund on obligations issued by the State of Maryland,
its political subdivisions, Puerto Rico, the U.S. Virgin Islands, or Guam and
their respective authorities or municipalities ("Maryland Exempt Obligations"),
will be exempt from Maryland state and local income taxes when distributed to a
shareholder of the Fund. Except as noted below, all other dividend
distributions will be subject to Maryland state and local income taxes.
    
      Capital gains distributed by the Fund to a shareholder or any gains
realized by a shareholder from a redemption or sale of shares must be
recognized for Maryland state and local income tax purposes to the extent
recognized for federal income tax purposes. However, capital gains
distributions included in the gross income of shareholders for federal income
tax purposes are subtracted from capital gains income for Maryland income tax
purposes to the extent such distributions are derived from the disposition of
debt obligations issued by the State of Maryland, its political subdivisions
and authorities.


                                                                               9
- --------------------------------------------------------------------------------
<PAGE>

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

      Dividends received by a shareholder from the Fund that are derived from
interest on U.S. government obligations will be exempt from Maryland state and
local income taxes. Entities subject to the financial institution franchise tax
will generally be subject to tax on distributions from the Fund.

      In the case of individuals, Maryland presently imposes an income tax on
items of tax preference with reference to such items as defined in the Code for
purposes of calculating the federal alternative minimum tax. Interest paid on
certain private activity bonds of an issuer other than the State of Maryland,
its political subdivisions, or authorities is a preference item taken into
account for this purpose. Accordingly, if the Fund holds such bonds, the excess
of 50% of that portion of exempt interest dividends that is attributable to
interest on such bonds over a threshold amount may be taxable by Maryland.
Interest on indebtedness incurred or continued (directly or indirectly) by a
shareholder in order to purchase or carry shares of the Fund will not be
deductible for Maryland state and local income tax purposes. Individuals will
not be subject to personal property tax on their shares of the Fund. Shares of
the Fund held by a Maryland resident at death may be subject to Maryland
inheritance and estate taxes.

MANAGEMENT OF THE FUND
    
- --------------------------------------------------------------------------------
   
      The overall business affairs of the Fund are managed by its Board of
Directors. The Board approves all significant agreements between the Fund and
persons or companies furnishing services to the Fund, includ-ing the Fund's
agreements with its investment advisor, distributor, custodian and transfer
agent. A majority of the Directors of the Fund have no affiliation with the
Advisor or the Distributor.

INVESTMENT ADVISOR
    
- --------------------------------------------------------------------------------
   
      Investment Company Capital Corp. ("ICC" or the "Advisor"), the Fund's
investment advisor, is an indirect subsidiary of Bankers Trust New York
Corporation. ICC is also the investment advisor to other mutual funds in the
Flag Investors family of funds and BT Alex. Brown Cash Reserve Fund, Inc., which
funds had approximately $5.5 billion of net assets as of May 31, 1997.

      ICC is responsible for the general management of the Fund, as well as for
decisions to buy and sell securities for the Fund, for broker-dealer selection,
and for negotiation of commission rates under standards established and
periodically reviewed by the Board of Directors. ICC currently intends to
waive, on a voluntary basis, its annual fee to the extent necessary so that
Total Fund Operating Expenses do not exceed 0.45% of the Institutional Shares'
average daily net assets. For the fiscal year ended March 31, 1997, ICC waived
all advisory fees, amounting to $79,698, and reimbursed expenses of $64,880.
    
      ICC also serves as the Fund's transfer and dividend disbursing agent and
provides accounting services to the Fund. (See "Custodian, Transfer Agent and
Accounting Services.")
   
Portfolio Managers

      Messrs. M. Elliott Randolph, Jr., and Paul D. Corbin, have shared primary
responsibility for managing the Fund's assets since inception.

      M. Elliott Randolph, Jr. has 23 years of investment experience and has
been a portfolio manager with the Advisor since 1991. From 1988-1991 he was a
Principal with Monument Capital Management, Inc.

      Paul D. Corbin has over 18 years of investment experience and has been a
portfolio manager with the Advisor since 1991. From 1984-1991 he served as the
Senior Vice President in charge of Fixed Income Portfolio Management at First
National Bank of Maryland.
    

<PAGE>
   
DISTRIBUTOR
    
- --------------------------------------------------------------------------------
   
      Effective September 1, 1997, ICC Distributors, Inc. ("ICC Distributors"
or the "Distributor") acts as distributor for each class of the Fund's shares.
Prior to September 1, 1997, Alex. Brown & Sons Incorporated served as
distributor for each class of the Fund's shares for the same compensation and
on substantially the same terms and conditions as ICC Distributors. ICC
Distributors is a registered broker-dealer that offers distribution services to
a variety of registered investment companies including the other funds in the
Flag Investors family of funds and BT Alex. Brown Cash Reserve Fund, Inc. ICC
Distributors is not affiliated with the Advisor.

      ICC Distributors receives no compensation for distributing the
Institutional Shares. ICC Distributors bears all expenses associated with
advertisements, promotional materials, sales literature and printing and
mailing prospectuses to individuals and entities other than Fund shareholders.

CUSTODIAN, TRANSFER AGENT AND ACCOUNTING SERVICES
- --------------------------------------------------------------------------------
   
      Investment Company Capital Corp. is the Fund's transfer and dividend
disbursing agent. ICC also provides accounting services to the Fund. As
compensation for providing accounting services to the Fund for the fiscal year
ended March 31, 1997, ICC received a fee equal to 0.11% of the Fund's average
daily net assets. (See the Statement of Additional Information.) PNC Bank,
National Association acts as custodian of the Fund's assets. The Fund's Board
of Directors has approved Bankers Trust Company, a subsidiary of Bankers Trust
New York Corporation and an affiliate of the Fund, as custodian. Currently, it
is anticipated that Bankers Trust Company will provide custodial services to
the Fund effective September 22, 1997.
 
    
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
   
      From time to time the Fund may advertise its performance including
comparisons to other mutual funds with similar investment objectives and to
relevant indices. Any quotations of yield of the Fund will be determined by
dividing the net investment income earned by the Fund during a 30-day period by
the maximum offering price per share on the last day of the period and
annualizing the result on a semi-annual basis. The Fund may also advertise a
"tax-equivalent yield," which is calculated by determining the rate of return
that would have to be achieved on a fully taxable investment to produce the
after-tax equivalent of the Fund's yield, assuming certain tax brackets for a
shareholder. All advertisements of performance will show the average annual
total return over one-, five- and ten-year periods or, if such periods have not
yet elapsed, shorter periods corresponding to the life of the Fund. Such total
return quotations will be computed by finding average annual compounded rates
of return over such periods that would equate an assumed initial investment of
$1,000 to the ending redeemable value according to the required standardized
calculation. The standardized calculation is required by the SEC to provide
consistency and comparability in investment company advertising and is not
equivalent to a yield calculation.

      If the Fund compares its performance to other funds or to relevant
indices, the Fund's performance will be stated in the same terms in which such
comparative data and indices are stated, which is normally total return rather
than yield.

      The performance of the Fund may be compared to data prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. and Morningstar
Inc., independent services that monitor the performance of mutual funds. The
Fund may also use total return performance data as reported in national,
financial and industry publications that monitor the performance of mutual
funds such as Money Magazine, Forbes, Business Week, Barron's, Investor's
Daily, IBC/Donoghue's Money Fund Report and The Wall Street Journal.

      Performance will fluctuate and any statement of performance should not be
considered as representative of the future performance of the Fund.
Shareholders should remember that performance is generally a function of the
type and quality of instruments held by the Fund, operating expenses and market
conditions. Any fees charged by financial institutions with respect to customer
accounts through which Institutional Shares may be purchased, although not
included in calculations of performance, will reduce performance results.
    
 
GENERAL INFORMATION
- --------------------------------------------------------------------------------


Description of Shares
   
      The Fund is an open-end, non-diversified management investment company
organized under the laws of the State of Maryland on July 23, 1993 and is
authorized to issue 40 million shares of capital stock, par value of $.001 per
share, all of which shares are designated common stock. Each share has one vote
and shall be entitled to dividends and distributions when and if declared by
the Fund. In the event of liquidation or dissolution of the Fund, each share
would be entitled to its pro rata portion of the Fund's assets after all debts
and expenses have been paid. The fiscal year-end of the Fund is March 31.

      The Board of Directors is authorized to establish additional series of
shares of capital stock, each of which would evidence interests in a separate
portfolio of securities, and separate classes of each series of the
    


                                                                              11

Fund. The shares offered by this Prospectus have been designated "Flag
Investors Maryland Intermediate Tax-Free Income Fund Institutional Shares." The
Board has no present intention of establishing any additional series of the Fund
but the Fund does have two other classes of shares in addition to the shares

of the Fund may be offered to certain investors and holders of such shares may
be entitled to certain exchange privileges not offered to Institutional Shares.

investments and advisory fee, but the classes may have different distribution
fees or sales load structures and the net asset value per share of the classes
may differ at times.
    

   
Annual Meetings

      Unless required under applicable Maryland law, the Fund does not expect
to hold annual meetings of shareholders. However, shareholders of the Fund
retain the right, under certain circumstances, to request that a meeting of

from office, and if such a request is made, the Fund will assist with the
shareholder communications in connection with the meeting.

 [ ] U.S. Citizen/Taxpayer:

     [ ] I certify that (1) the number shown above on this form is the correct

* Alex. Brown Capital Advisory & Trust Company intends, consistent with
  applicable legal requirements, to reimburse its clients at the account level
  in an amount such that the additional cost for client assets invested in
  ABCAT Shares is 0.20%. Absent this arrangement, clients would be subject to
  the expenses of the Fund shown above. In this regard, the Fund's investment
  advisor currently intends to waive its fee or to reimburse the Fund on a
  voluntary basis to the extent required so that Total Fund Operating Expenses
  do not exceed 0.45% of the ABCAT Shares' average daily net assets. Absent
  fee waivers and/or reimbursements, Management Fees would be 0.35%, Other
  Expenses would be 0.74% and Total Fund Operating Expenses would be 1.09% of
  the ABCAT Shares' average daily net assets.

indicated and have been audited by Deloitte & Touche LLP, independent auditors.

INVESTMENT PROGRAM

- --------------------------------------------------------------------------------
Investment Objective, Policies and
Risk Considerations


      The Fund seeks to provide current income exempt from federal income taxes
and Maryland state and local income taxes consistent with preservation of
principal within an intermediate-term maturity structure. There is no assurance
this objective will be met.


   
      Under normal conditions, the Fund expects to be as fully invested as
practicable in obligations that, in the opinion of bond counsel to the issuers,
produce interest exempt from federal income tax and Maryland state and local
income tax and at least 65% of the Fund's total assets will be invested in
securities of Maryland issuers. These include municipal obligations issued by
the State of Maryland and its political subdivisions, agencies or
instrumentalities. The Fund may invest up to 35% of its assets in obligations
of other issuers of securities the interest on which is exempt from Maryland
state and local taxes. These issuers would include territories or possessions
of the United States. However, the Fund has no present intention to invest in
securities issued by such territories or possessions.


      As a matter of fundamental policy, under normal conditions, the Fund will
invest at least 80% of its total assets in securities the interest on which is
exempt from federal and Maryland state and local income taxes and 80% of the
Fund's assets will be invested in municipal securities the income from which is
not subject to the alternative minimum tax. Income derived from securities
subject to the alternative minimum tax is not included when computing income
exempt from federal and Maryland state and local income taxes. Under normal
conditions, the Fund may invest up to 20% of its net assets in municipal
securities, the income from which is not exempt from Maryland state and local
income taxes. For temporary, defensive purposes when, in the opinion of the
Fund's investment advisor (the "Advisor"), securities exempt from Maryland
state and local income tax are not readily available or of sufficient quality,
the Fund can invest up to 100% of its assets in securities that pay interest
that is exempt only from federal income taxes or in taxable U.S. Treasury
securities.


      The Fund is a non-diversified investment company, which means that more
than 5% of its assets may be invested in each of one or more issuers. Since a
relatively high percentage of assets of the Fund may be invested in the
obligations of a limited number of issuers, the value of shares of the Fund may
be more susceptible to any single economic, political or regulatory occurrence
than the shares of a diversified investment company would be. The Fund intends
to satisfy the diversification requirements necessary to qualify as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code").
    
<PAGE>


      The Fund currently contemplates that it will not invest more than 25% of
its total assets (at market value at the time of purchase) in municipal
securities, the interest on which is paid from revenues of projects with
similar characteristics. See also "Special Considerations Relating To Maryland
Municipal Securities."


      Under normal circumstances the Fund's portfolio will have a dollar
weighted average maturity of between 3 and 10 years. The value of obligations
purchased by the Fund will change as interest rates change. Thus, a decrease in
interest rates generally will result in an increase in the value of shares of
the Fund. Conversely, an increase in interest rates will generally result in a
decrease in the value of the shares of the Fund. The magnitude of these
fluctuations will be greater as the average maturity of the Fund increases.


   
      Municipal notes in which the Fund may invest will be limited to those
obligations (i) that are rated MIG-1 or VMIG-1 at the time of investment by
Moody's Investors Service, Inc. ("Moody's"), (ii) that are rated SP-1 at the
time of investment by Standard & Poor's Ratings Group ("S&P"), or (iii) that,
if not rated by S&P or Moody's, are of comparable quality in the Advisor's
judgment. Municipal bonds in which the Fund may invest must be rated BBB or
better by S&P or Baa or better by Moody's at the time of investment or, if
unrated by S&P or Moody's must be of comparable quality in the Advisor's
judgment. Securities rated Baa or BBB are deemed to have speculative
characteristics. Tax-exempt commercial paper will be limited to investments in
obligations that are rated at least A-1 by S&P or Prime-1 by Moody's at the
time of investment or, if unrated by S&P or Moody's, are of comparable quality
in the Advisor's judgment. These ratings may be based in part on credit support
provided by a bank or other entity. Accordingly, a decline in the
creditworthiness of the entity providing such support could affect the rating
of the security, as well as the payment of interest and principal. For a
description of the above ratings, see the Appendix to the Statement of
Additional Information.
    


      The Fund may also enter into futures contracts and options on futures
contracts, although it has no present intention to do so. Gains recognized by
the Fund from such transactions would constitute taxable income to
shareholders.

<PAGE>

      The Fund may also purchase variable and floating rate demand notes and
bonds. The Advisor will invest in commitments to purchase securities on a
"when-issued" basis and reserves the right to engage in "put" transactions on a
daily, weekly or monthly basis.

Municipal Securities

      Municipal securities that the Fund may purchase consist of (i) debt
obligations issued by or on behalf of public authorities to obtain funds to be
used for various public facilities, for refunding outstanding obligations, for
general operating expenses and for lending such funds to other public
institutions and facilities, and (ii) certain private activity and industrial
development bonds issued by or on behalf of public authorities to obtain funds
to provide for the construction, equipment, repair or improvement of privately
operated facilities. Municipal notes include general obligation notes, tax
anticipation notes, revenue anticipation notes, bond anticipation notes,
certificates of indebtedness, demand notes, construction loan notes and
participation interests therein. Municipal bonds include general obligation
bonds, revenue or special obligation bonds, private activity bonds, industrial
development bonds and participation interests therein. General obligation bonds
are backed by the taxing power of the issuing municipality. Revenue bonds are
backed by the revenues of a project or facility (tolls from a toll bridge, or
lease payments, for example). The payment of principal and interest on private
activity and industrial development bonds generally is dependent solely on the
ability of the facility's user to meet its financial obligations and the
pledge, if any, of real and personal property so financed as security for such
payment.


   
      The Fund may purchase municipal lease obligations, including certificates
of participation ("COPs") in municipal leases. The Fund may acquire municipal
lease obligations that may be assigned by the lessee to another party provided
the obligation continues to provide tax-exempt interest. The Fund will not
purchase municipal lease obligations to the extent it holds municipal lease
obligations and illiquid securities in an amount exceeding 10% of its net
assets unless the Advisor determines that the municipal lease obligations are
liquid pursuant to guidelines established by the Board of Directors of the
Fund. Pursuant to these guidelines, the Advisor, in making this liquidity
determination, will consider, among other factors, the strength and nature of
the secondary market for such obligations, the prospect for its future
marketability and whether such obligations are rated. The Fund expects that it
will purchase only rated municipal lease obligations. In addition, the Fund may
purchase COPs representing interests in other municipal securities (such as
industrial development bonds). (See "Participation Interests.")
    
<PAGE>
   
      Municipal obligations purchased by the Fund that fall below the above
rating criteria after the purchase by the Fund shall be sold as promptly as
possible consistent with orderly disposition.
    

Insured Obligations

      The Fund may invest in obligations that are insured as to the scheduled
payment of all installments of principal and interest as they fall due. The
purpose of this insurance is to minimize credit risks to the Fund and its
shareholders associated with defaults in Maryland municipal obligations owned
by the Fund. This insurance does not insure against market risk and therefore
does not guarantee the market value of the obligations in the Fund's investment
portfolio upon which the net asset value of the Fund's shares is based. The
market value will continue to fluctuate in response to fluctuations in interest
rates or the bond market. Similarly, this insurance does not cover or guarantee
the value of the shares of the Fund. The ratings of the insured obligations may
be based in part on insurance provided by an insurance company. Accordingly, a
decline in the creditworthiness of the insurance company providing the
insurance could affect the rating of the security, as well as the payment of
interest and principal.

Participation Interests

   
      The Fund may invest in COPs representing participation interests in
municipal securities (such as AMT-Subject Bonds). A participation interest (i)
may pay a fixed, floating or variable rate of interest; (ii) gives the
purchaser an undivided interest in the municipal securities in the proportion
that the Fund's participation interest bears to the total principal amount of
the municipal securities; and (iii) provides a demand repurchase feature. Each
participation is backed by an irrevocable letter of credit or guarantee of a
bank that meets the prescribed quality standards of the Fund. The Fund has the
right to sell the instrument back to the issuing bank or draw on the letter of
credit on demand for all or any part of the Fund's participation interest in
the municipal security, plus accrued interest. Banks will retain or receive a
service fee, letter of credit fee and a fee for issuing repurchase commitments
in an amount equal to the excess of the interest paid on the municipal
securities over the negotiated yield at which the instruments were purchased by
the Fund. Participation interests in the form to be purchased by the Fund are
new instruments, and no ruling of the Internal Revenue Service has been secured
relating to their tax-exempt status. The Fund intends to purchase participation
interests based upon opinions of counsel to the issuer to the effect that
income from the participation interests is tax-exempt to the Fund. For purposes
of complying with diversification requirements, the Fund will treat both the
trust, or similar entity established to issue
    


                                                                               5
<PAGE>

COPs, and the issuers of the underlying municipal securities as issuers. Also,
the Fund will limit its investments in COPs to less than 25% of its total
assets.

Repurchase Agreements

   
      The Fund may agree to purchase U.S. Treasury securities from creditworthy
financial institutions, such as banks and broker-dealers, subject to the
seller's agreement to repurchase the securities at an established time and
price. Default by or bankruptcy proceedings with respect to the seller may,
however, expose the Fund to possible loss because of adverse market action or
delay in connection with the disposition of the underlying obligations.
    

Variable and Floating Rate Demand
Obligations

   
      The Fund may purchase variable and floating rate demand notes and bonds,
which are tax-exempt obligations normally having stated maturities in excess of
one year, but which permit the holder to demand payment of principal either at
any time or at specified intervals. The interest rates on these obligations
fluctuate from time to time in response to changes in the market interest
rates. Frequently, such obligations are secured by letters of credit or other
credit support arrangements provided by banks. Where these obligations are not
secured by letters of credit or other credit support arrangements, the Fund's
right to redeem will be dependent on the ability of the borrower to pay
principal and interest on demand. Each demand note and bond purchased by the
Fund will meet the quality criteria established for the purchase of other
municipal obligations. The Fund will not invest more than 10% of its net assets
in floating or variable rate demand obligations as to which the Fund cannot
exercise the demand feature on less than seven days' notice if there is no
secondary market available for these obligations.
    

When-Issued Securities

      When-issued securities are securities purchased for delivery beyond the
normal settlement date at a stated price and yield. The Fund will generally not
pay for such securities or start earning interest on them until they are
received. When-issued commitments will not be used for speculative purposes and
will be entered into only with the intention of actually acquiring the
securities. The securities so purchased or sold are subject to market
fluctuation so, at the time of delivery of the securities, their value may be
more or less than the purchase or sale price. The Fund will ordinarily invest
no more than 40% of its net assets at any time in municipal obligations
purchased on a when-issued basis.

Special Considerations Relating to Maryland Municipal Securities

   
      The Fund's concentration in securities issued by the State of Maryland
and its political subdivisions, agencies and instrumentalities involves greater
risk than a fund broadly invested across many states and municipalities. In
particular, changes in economic conditions and governmental policies of the
State of Maryland and its municipalities could adversely affect the value of
the Fund and the securities held by it. For a further description of these
risks, see "Risk Factors Associated with a Maryland Portfolio" in the Statement
of Additional Information.
    
<PAGE>
 
INVESTMENT RESTRICTIONS

- --------------------------------------------------------------------------------
   
  The Fund's investment program is subject to a number of restrictions that
reflect both self-imposed standards and federal regulatory limitations.


1) As a matter of fundamental policy, the Fund will not concentrate 25% or more
   of its total assets in securities of issuers in any one industry, provided
   that this limitation does not apply to investments in tax-exempt securities
   issued by governments or political subdivisions of governments (for these
   purposes the U.S. Government and its agencies and instrumentalities are not
   considered an issuer). This restriction may not be changed without
   shareholder approval.

2) Additionally, the Fund will not invest more than 10% of the Fund's net assets
   in illiquid securities, including repurchase agreements with maturities of
   greater than seven days. This restriction may be changed by a vote of the
   Board of Directors.
    

      The Fund is subject to further investment restrictions that are set forth
in the Statement of Additional Information.

HOW TO INVEST IN ABCAT SHARES
    

- --------------------------------------------------------------------------------
      Alex. Brown Capital Advisory & Trust Company and its affiliates may
acquire ABCAT Shares on behalf of their discretionary accounts by placing
orders with the Fund's distributor (the "Distributor"). Beneficial ownership of
ABCAT Shares will be reflected on books maintained by Alex. Brown Capital
Advisory & Trust Company or an affiliate. There is no minimum for initial or
subsequent investments in ABCAT Shares.

   
      It is the responsibility of Alex. Brown Capital Advisory & Trust Company
and its affiliates to transmit orders for ABCAT Share purchases and to deliver
required funds to the Distributor. Orders for purchases of ABCAT Shares are
accepted on any day on which the New York Stock Exchange is open for business
(a "Business Day"). Purchase orders for ABCAT Shares will be executed at a per
share purchase price equal to the net asset value next determined after receipt
of the purchase order and immediately available funds. The Fund reserves the
right to suspend the sale of ABCAT Shares at any time or reject any order.

      The net asset value per share is determined daily as of the close of the
New York Stock Exchange, which is ordinarily 4:00 p.m. (Eastern Time), on each
Business Day. Net asset value per share of a class is calculated by valuing its
share of the Fund's assets, deducting all liabilities attributable to that
class, and dividing the resulting amount by the number of then outstanding
shares of the class. For this purpose, portfolio securities are given their
market value where feasible. Securities or other assets for which market
quotations are not readily available are valued at their fair value as
determined in good faith under procedures established from time to time and
monitored by the Fund's Board of Directors. Such procedures may include the use
of an independent pricing service, which uses prices based upon yields or
prices of securities of comparable quality, coupon, maturity and type;
indications as to values from dealers; and general market conditions. Debt
obligations with maturities of 60 days or less will be valued at amortized
cost, which constitutes fair value as determined by the Fund's Board of
Directors.
    
      In the interest of economy and convenience and because of the operating
procedures for the ABCAT Shares, certificates representing such shares will not
be issued. Beneficial owners of ABCAT Shares ("Shareholders") will have the
same rights and ownership with respect to such shares as if certificates had
been issued.

<PAGE>

   
 
HOW TO REDEEM ABCAT SHARES
    

- --------------------------------------------------------------------------------
   
      ABCAT Shares may be redeemed by, or at the direction of, Alex. Brown
Capital Advisory & Trust Company or an affiliate, as appropriate, on any
Business Day by transmission of a redemption order through the Distributor, or
by regular or express mail to the Fund's transfer agent (the "Transfer Agent")
at its address listed on the back cover of this Prospectus. A redemption is
effected at the net asset value per share next determined after receipt of the
order in proper form. Redemption orders received after 4:00 p.m. (Eastern Time),
or the close of the New York Stock Exchange, whichever is earlier, will be
effected at the net asset value next determined on the following Business Day.
Payment for redeemed ABCAT Shares will be made to, or at the direction of, Alex.
Brown Capital Advisory & Trust Company or an affiliate, as appropriate, for the
benefit of Shareholders. Payment will be made as promptly as feasible and, under
most circumstances, within three Business Days.
    
      Dividends payable up to the date of the redemption of ABCAT Shares will
be paid on the next dividend payment date.
   
 
DIVIDENDS AND TAXES
    
- --------------------------------------------------------------------------------
Dividends and Distributions

   
      The Fund's policy is to distribute to shareholders substantially all of
its taxable net investment income (including net short-term capital gains) in
the form of monthly dividends. The Fund may distribute to shareholders any net
capital gains (net long-term capital gains less net short-term capital losses)
on an annual basis or, alternatively, may elect to retain net capital gains and
pay tax thereon.
    
      Unless other arrangements are made, all income dividends (consisting of
dividend and interest income and the excess, if any, of net short-term capital
gains over net long-term capital losses) and net capital gains distributions,
if any, will be reinvested in additional ABCAT Shares at net asset value.

Tax Treatment of Dividends and Distributions

   
      The following summary of certain federal income tax consequences is based
on current tax laws and
    


                                                                               7
<PAGE>

   
regulations, which may be changed by legislative, judicial or administrative
action. No attempt has been made to present a detailed explanation of the
federal, state or local income tax treatment of the Fund or the Shareholders,
and the discussion here is not intended as a substitute for careful tax
planning. Accordingly, shareholders are advised to consult their tax advisors
regarding specific questions as to federal, state and local income taxes.

      The Statement of Additional Information sets forth further information
concerning taxes.

      The Fund intends to continue to qualify as a "regulated investment
company" under the Code and to distribute to its investors all of its net
investment income (including its net tax-exempt income) and net short-term and
long-term capital gain income, if any, so that it is not required to pay
federal income taxes on amounts so distributed. In addition, the Fund expects
to make sufficient distributions prior to the end of each calendar year to
avoid liability for federal excise tax. The Fund will provide advice annually
as to the federal income tax consequences of distributions made during the
year.
    

Dividends derived from the Fund's net exempt-interest income and designated by
the Fund as exempt-interest dividends may be treated by Shareholders as items
of interest excludable from their gross income for federal income tax purposes
if the Fund qualifies as a regulated investment company and if, at the close of
each quarter of the Fund's taxable year, at least 50% of the value of its total
assets consists of securities the interest on which is excluded from gross
income. Although exempt-interest dividends are excludable from a Shareholder's
gross income for regular income tax purposes, they may have collateral federal
income tax consequences, including alternative minimum tax consequences. (See
the Statement of Additional Information.)

   
      Current federal tax law limits the types and volume of bonds qualifying
for the federal income tax exemption of interest, which may have an effect on
the ability of the Fund to purchase sufficient amounts of tax-exempt securities
to satisfy the Code's requirements for the payment of exempt-interest
dividends. All or a portion of the interest on indebtedness incurred or
continued by a Shareholder to purchase or carry ABCAT Shares may not be
deductible for federal income tax purposes. Furthermore, entities or persons
who are "substantial users" (or persons related to "substantial users") of
facilities financed by "private activity bonds" or "industrial development
bonds" should consult their tax advisors before purchasing ABCAT Shares.
    

<PAGE>
   
      Under the Code, dividends attributable to interest on certain "private
activity bonds" issued after August 7, 1986, will be included in alternative
minimum taxable income for the purpose of determining liability (if any) for
the alternative minimum tax for individuals and for corporations. Additionally,
in the case of corporations, all tax-exempt interest dividends will be taken
into account in determining "adjusted current earnings" (as defined for federal
income tax purposes) for purposes of computing the alternative minimum tax
imposed on corporations.

      To the extent, if any, that dividends paid to investors are derived from
taxable income, such dividends will be subject to federal income tax. In
addition, as substantially all of the Fund's income is expected to be derived
from earned interest, it is anticipated that no portion of the Fund's
distributions will be eligible for the corporate dividends-received deduction.
If the Fund purchases a municipal security at a market discount, any gain
realized by the Fund upon sale or redemption of the municipal obligation shall
be treated as taxable interest income to the extent such gain does not exceed
the market discount and any gain realized in excess of the market discount will
be treated as capital gain. Distributions of net investment income and/or the
excess, if any, of net short-term capital gains over net long-term capital
losses are taxable to investors as ordinary income, regardless of whether such
distributions are paid in cash or reinvested in additional ABCAT Shares.
Distributions of net capital gains (the excess of net long-term capital gains
over net short-term capital losses) that are designated by the Fund as capital
gain dividends are taxable to investors as long-term capital gains, regardless
of the length of time the investor owned the ABCAT Shares.

      Ordinarily, Shareholders will include all dividends declared by the Fund
as income in the year of payment. However, dividends declared payable to
shareholders of record in December of one year, but paid in January of the
following year, will be deemed for tax purposes to have been received by the
Shareholders and paid by the Fund in the year in which the dividends were
declared.

      The Fund intends to make sufficient distributions of its ordinary income
and capital gain net income prior to the end of each calendar year to avoid
liability for federal exise tax.
    
      The sale, exchange or redemption of ABCAT Shares is a taxable event to
the Shareholder.

Maryland Tax Disclosure
   
      To the extent the Fund qualifies as a regulated investment company under
the Code, it will be subject to tax only on (1) that portion of its income on
which tax is imposed for federal income tax purposes under Section 852(b)(1) of
the Code and (2) that portion of its
    


8
<PAGE>

   
income that consists of federally tax-exempt interest on obligations other than
Maryland Exempt Obligations (hereinafter defined) to the extent such interest
is not paid to Shareholders in the form of exempt-interest dividends. To the
extent dividends paid by the Fund represent interest excludable from gross
income for federal income tax purposes, that portion of exempt-interest
dividends that represents interest received by the Fund on obligations issued
by the State of Maryland, its political subdivisions, Puerto Rico, the U.S.
Virgin Islands, or Guam and their respective authorities or municipalities
("Maryland Exempt Obligations"), will be exempt from Maryland state and local
income taxes when distributed to a Shareholder. Except as noted below, all
other dividend distributions will be subject to Maryland state and local income
taxes.

      Capital gains distributed by the Fund to a Shareholder or any gains
realized by a Shareholder from a redemption or sale of shares must be
recognized for Maryland state and local income tax purposes to the extent
recognized for federal income tax purposes. However, capital gains
distributions included in the gross income of Shareholders for federal income
tax purposes are subtracted from capital gains income for Maryland income tax
purposes to the extent such distributions are derived from the disposition of
debt obli-gations issued by the State of Maryland, its political subdivisions
and authorities.
    

      Dividends received by a Shareholder from the Fund that are derived from
interest on U.S. government obligations will be exempt from Maryland state and
local income taxes. Entities subject to the financial institution franchise tax
will generally be subject to tax on distributions from the Fund.

   
      In the case of individuals, Maryland presently imposes an income tax on
items of tax preference with reference to such items as defined in the Code for
purposes of calculating the federal alternative minimum tax. Interest paid on
certain private activity bonds of an issuer other than the State of Maryland,
its political subdivisions, or authorities is a preference item taken into
account for this purpose. Accordingly, if the Fund holds such bonds, the excess
of 50% of that portion of exempt interest dividends that is attributable to
interest on such bonds over a threshold amount may be taxable by Maryland.
Interest on indebtedness incurred or continued (directly or indirectly) by a
Shareholder in order to purchase or carry shares of the Fund will not be
deductible for Maryland state and local income tax purposes. Individuals will
not be subject to personal property tax on their shares of the Fund. Shares of
the Fund held by a Maryland resident at death may be subject to Maryland
inheritance and estate taxes.

MANAGEMENT OF THE FUND

- --------------------------------------------------------------------------------
   
      The overall business affairs of the Fund are managed by its Board of
Directors. The Board approves all significant agreements between the Fund and
persons or companies furnishing services to the Fund, includ-ing the Fund's
agreements with its investment advisor, distributor, custodian and transfer
agent. A majority of the Directors of the Fund have no affiliation with the
Distributor or the Advisor.
 
    
INVESTMENT ADVISOR

- --------------------------------------------------------------------------------
   
      Investment Company Capital Corp. ("ICC" or the "Advisor"), the Fund's
investment advisor, is an indirect subsidiary of Bankers Trust New York
Corporation and an affiliate of Alex. Brown Capital Advisory & Trust Company.
ICC is also the investment advisor to other mutual funds in the Flag Investors
family of funds and BT Alex. Brown Cash Reserve Fund, Inc., which funds had
approximately $5.5 billion of net assets as of May 31, 1997.

      ICC is responsible for the general management of the Fund, as well as for
decisions to buy and sell securities for the Fund, for broker-dealer selection,
and for negotiation of commission rates under standards established and
periodically reviewed by the Board of Directors. ICC currently intends to
waive, on a voluntary basis, its annual fee to the extent necessary so that
Total Fund Operating Expenses do not exceed 0.45% of the ABCAT Shares' average
daily net assets. For the fiscal year ended March 31, 1997, ICC waived all
advisory fees, amounting to $79,698, and reimbursed expenses of $64,880.


      ICC also serves as the Fund's transfer and dividend disbursing agent and
provides accounting services to the Fund. (See "Custodian, Transfer Agent and
Accounting Services.")

DISTRIBUTOR

- --------------------------------------------------------------------------------
   
      Effective September 1, 1997, ICC Distributors, Inc. ("ICC Distributors"
or the "Distributor") acts as distributor for each class of the Fund's shares.
Prior to September 1, 1997, Alex. Brown & Sons Incorporated served as
distributor for each class of the Fund's shares for the same compensation and
on substantially the same terms and conditions as ICC Distributors. ICC
Distributors is a registered broker-dealer that offers distribution services to
a variety of registered investment companies including the other funds in the
Flag Investors family of funds and BT Alex. Brown Cash Reserve Fund, Inc. ICC
Distributors is not affiliated with the Advisor.


      ICC Distributors receives no compensation for distributing the ABCAT
Shares. ICC Distributors bears all expenses associated with advertisements,
promotional materials, sales literature and printing and mailing prospectuses
to individuals and entities other than Fund shareholders.

CUSTODIAN, TRANSFER AGENT AND ACCOUNTING SERVICES

- --------------------------------------------------------------------------------
      ICC is the Fund's transfer and dividend disbursing agent and provides
accounting services to the Fund. As compensation for providing accounting
services for the fiscal year ended March 31, 1997, ICC received from the Fund a
fee equal to 0.11% of the Fund's average daily net assets. (See the Statement
of Additional Information.) PNC Bank, National Association acts as custodian of
the Fund's assets. The Fund's Board of Directors has approved Bankers Trust
Company, a subsidiary of Bankers Trust New York Corporation and an affiliate of
the Fund, as custodian. Currently, it is anticipated that Bankers Trust Company
will provide custodial services to the Fund effective September 22, 1997.
 
    
PERFORMANCE INFORMATION

- --------------------------------------------------------------------------------
   
      From time to time the Fund may advertise its performance including
comparisons to other mutual funds with similar investment objectives and to
relevant indices. Any quotations of yield of the Fund will be determined by
dividing the net investment income earned by the Fund during a 30-day period by
the maximum offering price per share on the last day of the period and
annualizing the result on a semi-annual basis. The Fund may also advertise a
"tax-equivalent yield," which is calculated by determining the rate of return
that would have to be achieved on a fully taxable investment to produce the
after-tax equivalent of the Fund's yield, assuming certain tax brackets for a
Shareholder. All advertisements of performance will show the average annual
total return over one-, five- and ten-year periods or, if such periods have not
yet elapsed, shorter periods corresponding to the life of the Fund. Such total
return quotations will be computed by finding average annual compounded rates
of return over such periods that would equate an assumed initial investment of
$1,000 to the ending redeemable value according to the required standardized
calculation. The standardized calculation is required by the SEC to provide
consistency and comparability in investment company advertising and is not
equivalent to a yield calculation.

      If the Fund compares its performance to other funds or to relevant
indices, the Fund's performance will be stated in the same terms in which such
comparative data and indices are stated, which is normally total return rather
than yield.

      The performance of the Fund may be compared to data prepared by Lipper
Analytical Services, Inc., CDA Investment Technologies, Inc. and Morningstar
Inc., independent services that monitor the performance of mutual funds. The
Fund may also use total return performance data as reported in national,
financial and industry publications that monitor the performance of mutual
funds such as Money Magazine, Forbes, Business Week, Barron's, Investor's
Daily, IBC/Donoghue's Money Fund Report and The Wall Street Journal.

      Performance will fluctuate and any statement of performance should not be
considered as representative of the future performance of the Fund. Performance
is generally a function of the type and quality of instruments held by the
Fund, operating expenses and market conditions.
    
GENERAL INFORMATION

- --------------------------------------------------------------------------------
Description of Shares

   
      The Fund is an open-end, non-diversified management investment company
organized under the laws of the State of Maryland on July 23, 1993 and is
authorized to issue 40 million shares of capital stock, par value of $.001 per
share, all of which shares are designated common stock. Each share has one vote
and shall be entitled to dividends and distributions when and if declared by
the Fund. In the event of liquidation or dissolution of the Fund, each share
would be entitled to its pro rata portion of the Fund's assets after all debts
and expenses have been paid. The fiscal year-end of the Fund is March 31.

      The Board of Directors is authorized to establish additional series of
shares of capital stock, each of which would evidence interests in a separate
portfolio of securities, and separate classes of each series of the Fund. The
shares offered by this Prospectus have been designated "Alex. Brown Capital
Advisory & Trust Maryland Intermediate Tax-Free Income Shares." The Board has
no present intention of establishing any additional series of the Fund but the
Fund does have two other classes of shares in addition to the shares offered
hereby: "Flag Investors Maryland Intermediate Tax-Free Income Fund Class A
Shares," and "Flag Investors Maryland Intermediate Tax-Free Income Fund
Institutional Shares." Additional information concerning the Fund's other
classes of shares may be obtained by calling the Fund at (800) 767-3524.
Different classes of the Fund may be offered to certain investors and holders
of such shares may be entitled to certain exchange privileges not offered to
ABCAT Shares. All classes of the Fund share a common investment objective,
portfolio of investments and advisory fee, but the classes may have different
distribution fees or sales load structures and the net asset value per share of
the classes may differ at times.

Annual Meetings
      Unless required under applicable Maryland law, the Fund does not expect
to hold annual meetings of shareholders. However, shareholders of the Fund
retain the right, under certain circumstances, to request that a meeting of
shareholders be held for the purpose of considering the removal of a Director
from office, and if such a request is made, the Fund will assist with
shareholder communications in connection with the meeting.

Reports
      The Fund furnishes semi-annual reports containing information about the
Fund and its operations, including a list of investments held in the Fund's
portfolio and financial statements. The annual financial statements are audited
by the Fund's independent auditors, Deloitte & Touche LLP.

Shareholder Inquiries
      Shareholders with inquiries concerning their ABCAT Shares should contact
their account manager at Alex. Brown Capital Advisory & Trust Company.
