USAA Investment  Management  Company  manages these Funds.  For easier reading,
USAA  Investment  Management  Company  will  be  referred  to as  "we"  or "us"
throughout the Prospectus.

WHAT ARE EACH FUND'S INVESTMENT OBJECTIVES AND MAIN STRATEGIES?

Each Fund has a common investment objective of providing Florida investors with
a high level of current  interest  income  that is exempt from  federal  income
taxes and shares that are exempt from the Florida intangible  personal property
tax.  The  Florida  Tax-Free  Money  Market  Fund has a  further  objective  of
preserving capital and maintaining liquidity. Each Fund has separate investment
policies to achieve its objective.

The   FLORIDA   TAX-FREE   INCOME  FUND   invests   primarily   in   long-term,
investment-grade   Florida   tax-exempt   securities.    The   Fund's   average
dollar-weighted  portfolio  maturity is not  restricted,  but is expected to be
greater than 10 years.

The  FLORIDA  TAX-FREE  MONEY  MARKET  FUND  invests  in  high-quality  Florida
tax-exempt securities with maturities of 397 days or less.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Funds' objectives will be achieved.  See FUND INVESTMENTS on
page 9 for more information.

MAIN RISKS OF INVESTING IN THESE FUNDS

The two primary  risks of  investing  in these Funds are credit risk and market
risk. As with other mutual  funds,  losing money is also a risk of investing in
these Funds.

*  CREDIT RISK  involves  the  possibility  that a borrower  cannot make timely
   interest and principal payments on its securities.

*  MARKET  RISK  involves  the  possibility  that  the  value  of  each  Fund's
   investments  will decline  because of an increase in interest  rates,  or to
   adverse  changes in supply and demand  for  municipal  securities,  or other
   market factors.

These credit and market risks may be magnified  because each Fund  concentrates
in Florida tax-exempt securities.

IF INTEREST RATES INCREASE:  the yield of each Fund may increase and the market
value of the Florida  Tax-Free  Income Fund's  securities  will likely decline,
adversely affecting the net asset value and total return.

IF INTEREST RATES DECREASE:  the yield of each Fund may decrease and the market
value of the Florida  Tax-Free  Income Fund's  securities  may increase,  which
would likely increase the Fund's net asset value and total return.  The Florida
Tax-Free Money Market Fund's total return may decrease.

                                       2

Other risks of investing in either Fund include call risk and structural risk.

As you consider an investment in either Fund, you should also take into account
your tolerance for the daily  fluctuations of the financial markets and whether
you can afford to leave your money in the  investment  for long periods of time
to ride out down periods.

An investment in either Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance  Corporation  or any other  government  agency.  Although the Florida
Tax-Free Money Market Fund seeks to preserve the value of your investment at $1
per share, it is possible to lose money by investing in the Fund.

[CAUTION LIGHT GRAPHIC]

information about the main risks you will face as a Fund shareholder.

Either  Fund by itself  does not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE?

Yes, it could.  In fact, the value of your  investment in the Florida  Tax-Free
Income Fund will fluctuate with the changing  market values of the  investments
in the Fund.  We manage the Florida  Tax-Free  Money Market Fund in  accordance
with strict  Securities and Exchange  Commission (SEC)  guidelines  designed to
preserve  the Fund's  value at $1 per  share,  although,  of course,  we cannot
guarantee that the value will remain at $1 per share.

The value of the securities in which the Florida  Tax-Free  Income Fund invests
typically  fluctuates  inversely  with changes in the general level of interest
rates.  Changes in the  creditworthiness of issuers and changes in other market
factors such as the  relative  supply of and demand for  tax-exempt  bonds also
create value  fluctuations.  The bar charts shown below  illustrate  the Funds'
volatility and performance from year to year over the life of the Funds.

TOTAL RETURN

All mutual funds must use the same formula to calculate total return.

     [SIDE BAR]
     TOTAL  RETURN   MEASURES  THE  PRICE  CHANGE  IN  A  SHARE   ASSUMING  THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

YIELD

All mutual funds must use the same  formulas to calculate  yield and  effective
yield.

     [SIDE BAR]
     YIELD IS THE ANNUALIZED  NET INCOME OF THE FUND DURING A SPECIFIED  PERIOD
     AS A PERCENTAGE OF THE FUND'S SHARE PRICE.

     [SIDE BAR]
     EFFECTIVE  YIELD  IS  CALCULATED  SIMILAR  TO  THE  YIELD,  HOWEVER,  WHEN
     ANNUALIZED, THE INCOME EARNED IS ASSUMED TO BE REINVESTED.

Florida Tax-Free Income Fund

The Florida Tax-Free Income Fund may advertise performance in terms of a 30-day
yield  quotation or a  tax-equivalent  yield.  The Fund's  30-day yield for the
period ended December 31, 1998, was 4.52%.

Florida Tax-Free Money Market Fund

The Florida  Tax-Free  Money Market Fund  typically  advertises  performance in
terms of a 7-day  yield and  effective  yield or  tax-equivalent  yield and may
advertise total return. The 7-day yield quotation more closely reflects current
earnings of the Fund than the total return quotation.  The effective yield will
be slightly  higher  than the yield  because of the  compounding  effect of the
assumed  reinvestment.  Current yields and effective yields fluctuate daily and
will vary with  factors  such as  interest  rates  and the  quality,  length of
maturities,  and type of investments  in the portfolio.  The Fund's 7-day yield
for the period ended December 31, 1998, was 3.22%.

You may obtain the most current  yield  information  for either of the Funds by
calling 1-800-531-8777.

TAX-EQUIVALENT YIELD

Investors use  tax-equivalent  yields to compare  taxable and tax-exempt  fixed
income investments using a common yield measure.  The  tax-equivalent  yield is
the  yield  that a fully  taxable  investment  must  generate  to earn the same
"take-home" yield as a tax-exempt investment. The calculation depends upon your
federal marginal and Florida  intangible tax rates and assumes that an investor
can fully itemize  deductions on his or her federal tax return. The higher your
marginal tax bracket,  the higher will be the tax-equivalent yield and the more
valuable is the Fund's tax exemption.

                                       6
<PAGE>
For  example,  if you assume a federal  marginal  tax rate of 36% and a Florida
Intangible Tax Effect of .12%, the Effective Marginal Tax Rate would be 36.08%.
Using this tax rate,  the Funds'  tax-equivalent  yields for the period  ending
December 31, 1998, would be as follows:

===============================================================================
                                                           TAX-EQUIVALENT
                                                 YIELD          YIELD
- -------------------------------------------------------------------------------
  Florida Tax-Free Income Fund (30 day)          4.52%          7.07%
  Florida Tax-Free Money Market Fund (7 day)     3.22%          5.04%
===============================================================================

Using the example,  to exceed the 30-day yield of the Florida  Tax-Free  Income
Fund on an  after-tax  basis,  you must find a fully  taxable  investment  that
yields  more than  7.07%.  Likewise,  to exceed the 7-day  yield of the Florida
Tax-Free  Money  Market Fund,  you must find a fully  taxable  investment  that
yields more than 5.04%.

For more information on calculating  tax-equivalent  yields,  see APPENDIX B on
page 33.

objectives and policies and market conditions during the reported time periods.

   We have again  voluntarily  agreed to limit each Fund's  annual  expenses to
   .50% of its ANA and will  reimburse  the Funds for all expenses in excess of
   that amount until August 1, 2000.

Example of Effect of the Funds' Operating Expenses

This example  provides you a comparison of investing in one of these Funds with
the cost of investing in other mutual funds.  Although your actual costs may be
higher or lower, you would pay the following expenses on a $10,000  investment,
assuming (1) 5% annual return,  (2) the Fund's  operating  expenses (before any
applicable  reimbursements)  remain  the same,  and (3) you  redeem all of your
shares at the end of those periods.

FUND INVESTMENTS

Principal Investment Strategies and Risks

  Q  What is each Funds' principal investment strategy?

  A  Each Fund's principal  investment  strategy is to invest the Fund's assets
     primarily  in  securities  issued by the state of Florida,  its  political
     subdivisions and instrumentalities, and by other governmental entities if,
     in the opinion of counsel,  the interest from such obligations is excluded
     from gross income for federal income tax purposes and the  obligations are
     exempt from the Florida intangible personal property tax.

     These securities  include municipal debt obligations that have been issued
     by Florida and its political subdivisions,  and duly constituted state and
     local  authorities  and  corporations.  We refer to  these  securities  as
     Florida tax-exempt securities. Florida tax-exempt securities are issued to
     fund public infrastructure projects such as streets and highways, schools,
     water and sewer systems,  hospitals, and airports. They may also be issued
     to  refinance  outstanding  obligations  as well as to  obtain  funds  for
     general operating expenses and for loans to other public  institutions and
     facilities.

     Because the projects  benefit the public,  Congress has granted  exemption
     from  federal  income  taxes for the  interest  income  arising from these
     securities.  Likewise,  the Florida  Legislature  has granted an exemption
     from state intangible  personal  property taxes for most Florida municipal
     securities.

  Q  What  types of  tax-exempt  securities  will be  included  in each  Fund's
     portfolio?

  A  Each  Fund's  assets may be invested  in any of the  following  tax-exempt
     securities:

                                       9
<PAGE>
       * general  obligation bonds, which are secured by the issuer's pledge of
         its full faith,  credit, and taxing power for the payment of principal
         and interest;

       * revenue  bonds, which are  payable  from the  revenue  derived  from a
         particular  facility or class of  facilities  or, in some cases,  from
         annual  appropriations made by the state legislature for the repayment
         of interest and principal or other specific  revenue  source,  but not
         from the general taxing power;

       * lease obligations backed by the municipality's  covenant to budget for
         the payments due under the lease obligation;

       * synthetic  instruments,   which  combine  a  municipality's  long-term
         obligation  to  pay  interest  and  principal  with  another  person's
         obligation to repurchase the instrument on short notice; and

       * industrial  development  bonds  issued  by  or  on  behalf  of  public
         authorities to obtain funds for privately-operated facilities.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may invest up to 100% of each  Fund's  assets in
     short-term  securities  whether or not they are exempt from federal income
     tax and Florida  intangible  personal  property  taxes. To the extent that
     these temporary investments produce taxable income, that income may result
     in that Fund not fully achieving its investment  objective during the time
     it is in this temporary defensive posture.

  Q  What are the principal  risks  associated  with  investments in tax-exempt
     securities?

  A  The two principal  risks of investing in tax-exempt  securities are credit
     risk and market risk.

[CAUTION LIGHT GRAPHIC]
     CREDIT  RISK.  Credit  risk is the  possibility  that an issuer of a fixed
     income  security  will  fail  to  make  timely  payments  of  interest  or
     principal.  We attempt to minimize the Funds' credit risks by investing in
     securities  considered at least  investment grade at the time of purchase.
     Nevertheless,  even investment-grade securities are subject to some credit
     risk. In addition,  the ratings of securities  are estimates by the rating
     agencies of the credit quality of the securities. The ratings may not take
     into account every risk related to whether  interest or principal  will be
     repaid on a timely basis.

     When evaluating  potential  investments  for the Funds,  our analysts also
     independently  assess credit risk and its impact on the Funds' portfolios.
     Securities in the lowest investment grade ratings category

                                      10
<PAGE>
     (BBB) have speculative characteristics.  Changes in economic conditions or
     other  circumstances  are more likely to lead to a weakened  capability to
     make principal and interest  payments on these securities than is the case
     for higher-rated securities.

     [CAUTION LIGHT GRAPHIC]
     MARKET RISK. As a mutual fund investing in bonds, the Funds are subject to
     the risk that the market value of the bonds will decline because of rising
     interest rates.  Bond prices are linked to the prevailing  market interest
     rates.  In general,  when interest  rates rise,  bond prices fall and when
     interest rates fall, bond prices rise. The price volatility of a bond also
     depends on its maturity. Generally, the longer the maturity of a bond, the
     greater its  sensitivity to interest  rates.  To compensate  investors for
     this higher  market risk,  bonds with longer  maturities  generally  offer
     higher yields than bonds with shorter maturities.

  Q  What other risks are associated with investments in tax-exempt securities?

  A  Two other risks that are applicable  to certain  tax-exempt securities are
     call risk and structural risk.

[CAUTION LIGHT GRAPHIC]
     CALL RISK.Many municipal bonds may be "called," or redeemed, by the issuer
     before the stated maturity.  During a period of declining  interest rates,
     an issuer would call,  or refinance,  a higher  yielding bond for the same
     reason that a homeowner  would  refinance a home mortgage.  Interest rates
     must drop  sufficiently  so that the savings  more than offset the cost of
     refinancing.

     Intermediate-  and long-term  municipal bonds have the greatest call risk,
     because most municipal  bonds may not be called until after ten years from
     the date of  issue.  The  period  of "call  protection"  may be  longer or
     shorter than ten years,  but regardless,  bonds  purchased  closest to the
     date of issue will have the most call  protection.  Typically,  bonds with
     original maturities of ten years or less are not callable.

     Although  investors  certainly  appreciate  the rise in bond  prices  when
     interest  rates  drop,  falling  interest  rates  create  the  environment
     necessary to "call" the  higher-yielding  bonds from your Fund. When bonds
     are called,  the Fund is impacted in several  ways.  Most likely,  we must
     reinvest the bond-call proceeds at lower interest rates. The Fund's income
     may drop as a result. The Fund may also realize a taxable capital gain.

[CAUTION LIGHT GRAPHIC]
     STRUCTURAL  RISKS. Some tax-exempt  securities,  referred to as "synthetic
     instruments,"  are created by combining a long-term  municipal bond with a
     right to sell the instrument back to the

                                      11
<PAGE>
     remarketer or liquidity provider for repurchase on short notice,  referred
     to as a "tender option." Usually,  the tender option is backed by a letter
     of credit or similar  guarantee from a bank. The  guarantee,  however,  is
     conditional,  which  means that the bank is not  required to pay under the
     guarantee if there is a default by the  municipality  or if certain  other
     events occur. These types of instruments  involve special risks,  referred
     to as  "structural  risk."  For  example,  because of the  structure  of a
     synthetic  instrument,  there is a risk that the instrument  will lose its
     tax-exempt  treatment  or that we will not be able to exercise  our tender
     option.  We will not purchase a synthetic  instrument  unless  counsel has
     issued an opinion that the instrument is entitled to tax-exempt treatment.
     In  addition,  we  will  not  purchase  a  synthetic  instrument  for  the
     Tax-Exempt  Money Market Fund unless we believe there is only minimal risk
     that we will not be able to exercise our tender option at all times.

  Q  What  percentage  of each  Fund's  assets  will  be  invested  in  Florida
     tax-exempt securities?

  A  During  normal market  conditions,  at least 80% of each Fund's net assets
     will  consist of Florida  tax-exempt  securities.  This policy may only be
     changed by a shareholder vote.

     In addition to Florida tax-exempt securities, securities issued by certain
     U.S.  territories and possessions such as Puerto Rico, the Virgin Islands,
     and Guam are  exempt  from  federal  income  tax and the state  intangible
     personal property tax; and as such, we may consider investing up to 20% of
     each Fund's assets in these securities.

  Q  Are each Fund's investments diversified in many different issuers?

  A  Each Fund is considered  diversified  under the federal  securities  laws.
     This  means that we will not  invest  more than 5% in any one issuer  with
     respect to 75% of each Fund's assets. With respect to the remaining 25% of
     each  Fund's  assets,  we could  invest  more than 5% in any one, or more,
     issuers.  Purchases  of  securities  issued  or  guaranteed  by  the  U.S.
     Government or its agencies or instrumentalities are not counted toward the
     5%  limitation.  Each Fund,  of  course,  is  concentrated  geographically
     through the purchase of Florida tax-exempt securities.

     With  respect  to the  Florida  Tax-Free  Money  Market  Fund,  strict SEC
     guidelines  do not permit us to invest,  with respect to 75% of the

                                      12
<PAGE>
     Fund's assets,  greater than 10% of the Fund's assets in securities issued
     by or subject to guarantees by the same institution.

     We also may not invest  more than 25% of the Funds'  assets in  securities
     issued  in  connection   with  the  financing  of  projects  with  similar
     characteristics,  such as toll road revenue bonds,  housing revenue bonds,
     or electric power project  revenue bonds,  or in industrial  revenue bonds
     that are based, directly or indirectly,  on the credit of private entities
     of any one industry. However, we reserve the right to invest more than 25%
     of the Funds'  assets in  tax-exempt  industrial  revenue  bonds.  The 25%
     industry  limitation does not apply to general  obligation  bonds or bonds
     that are escrowed in U.S. Government securities.

  Q  What are the potential risks  associated with  concentrating  such a large
     portion of each Fund's assets in one state?

[CAUTION LIGHT GRAPHIC]
  A  The Funds are  subject to credit and market  risks,  as  described  above,
     which could be magnified by the Funds'  concentration  in Florida  issues.
     Florida  tax-exempt  securities  may be affected by  political,  economic,
     regulatory,  or other  developments  that  limit the  ability  of  Florida
     issuers to pay interest or repay principal in a timely manner.  Therefore,
     the Funds are affected by events within  Florida to a much greater  degree
     than a more diversified national fund.

     A particular development may not directly relate to the Funds' investments
     but  nevertheless   might  depress  the  entire  market  for  the  state's
     tax-exempt securities and therefore adversely impact the Funds' valuation.

     An  investment  in the Florida  Tax-Free  Money Market Fund may be riskier
     than an  investment  in other types of money market funds  because of this
     concentration.

     The  following  are  examples  of just some of the events that may depress
     valuations for Florida  tax-exempt  securities  for an extended  period of
     time:

       * Changes in state laws,  including  voter  referendums,  that  restrict
         revenues or raise costs for issuers.

       * Court  decisions  that affect a category of municipal  bonds,  such as
         municipal lease obligations or electric utilities.

       * Natural disasters such as floods, storms, hurricanes, droughts, fires,
         or earthquakes.

                                      13
<PAGE>
       * Bankruptcy  or  financial  distress  of a prominent  municipal  issuer
         within the state.

       * Economic issues that impact critical  industries or large employers or
         that weaken real estate prices.

       * Reductions in federal or state financial aid.

       * Imbalance  in  the  supply  and  demand  for  the  state's   municipal
         securities.

       * Developments  that may change the tax treatment of Florida  tax-exempt
         securities.

     In addition,  because each Fund invests in securities  backed by banks and
     other  financial  institutions,  changes  in the  credit  quality of these
     institutions could cause losses to a Fund and affect its share price.

     Other   considerations   affecting  the  Funds'   investments  in  Florida
     tax-exempt  securities  are  summarized  in the  Statement  of  Additional
     Information under SPECIAL RISK CONSIDERATIONS.

  Q  Will any portion of the distributions from the Funds be subject to federal
     income taxes?

  A  During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from gross income for federal income tax purposes and the
     shares will be exempt from the Florida  intangible  personal property tax.
     This policy may only be changed by a shareholder  vote. We expect that any
     taxable interest income distributed will be minimal.

     However,  gains and losses from trading  securities  that occur during the
     normal   course  of   managing  a  fund  may  create  net   capital   gain
     distributions.   The  Internal   Revenue  Code   presently   treats  these
     distributions differently than tax-exempt interest income in the following
     ways:

       * Distributions of net short-term  capital gains are taxable as ordinary
         income.

       * Distributions of net long-term  capital gains are taxable as long-term
         capital gains, regardless of the length of time you have held the Fund
         shares.

       * Both  short-term  and  long-term  capital  gains are  taxable  whether
         received in cash or reinvested in additional shares.

                                      14
<PAGE>
  Q  Do the Funds purchase municipal bonds secured by bond insurance?

  A  Yes. We  may  purchase  municipal  bonds   whose  principal  and  interest
     payments are  guaranteed  by an  insurance  company.  In addition,  we may
     purchase municipal bond insurance with Fund assets when we believe it will
     provide a net economic benefit to the shareholders.

  Q  Will income from the Funds be subject to the federal  alternative  minimum
     tax (AMT) for individuals?

  A  During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from the calculation of the federal  alternative  minimum
     tax  (AMT)  for  individuals.  This  policy  may  only  be  changed  by  a
     shareholder  vote.  Since  inception,  the Funds have not  distributed any
     income that is subject to the federal AMT for  individuals,  and we do not
     intend to invest in  securities  subject to the federal AMT.  However,  of
     course,  changes in  federal  tax laws or other  unforeseen  circumstances
     could result in income subject to the federal AMT for individuals.

Florida Tax-Free Income Fund

  Q  What is the credit quality of the Fund's investments?

  A  Under normal market  conditions,  we will invest the Fund's assets so that
     at least 50% of the total market  value of the  tax-exempt  securities  is
     rated within the three highest  long-term rating  categories (A or higher)
     by Moody's Investors Service,  Inc.  (Moody's),  Standard & Poor's Ratings
     Group  (S&P),  or Fitch IBCA,  Inc.  (Fitch) or in the highest  short-term
     rating  category by Moody's,  S&P, or Fitch. If a security is not rated by
     these  rating  agencies,  we  must  determine  that  the  security  is  of
     equivalent investment quality.

     In no event will we purchase a security for the Fund unless it is rated at
     least  investment   grade  at  the  time  of  purchase.   Investment-grade
     securities are those  securities  rated within the four highest  long-term
     rating  categories  by  Moody's  (Baa or  higher),  S&P,  or Fitch (BBB or
     higher),  or in the two  highest  short-term  rating  categories  by these
     rating agencies.  If unrated by these agencies, we must determine that the
     securities are of equivalent investment quality.

     On occasion, we may purchase a credit rating on a particular security when
     we believe it will provide a net economic benefit to the shareholders.

                                      15
<PAGE>
     You will find a complete  description of the above  tax-exempt  ratings in
     the Fund's Statement of Additional Information.

  Q  What happens if the rating of a security is downgraded to below investment
     grade?

  A  We  will  determine  whether  it is in the  best  interest  of the  Fund's
     shareholders to continue to hold the security in the Fund's portfolio.  If
     downgrades  result in more than 5% of the Fund's net assets being invested
     in securities that are less than  investment-grade  quality,  we will take
     immediate action to reduce the Fund's holdings in such securities to 5% or
     less of the Fund's net assets,  unless otherwise  directed by the Board of
     Trustees.

  Q  How are the decisions to buy and sell securities made?

  A  We manage  tax-exempt  funds based on the common  sense  premise  that our
     investors value tax-exempt income over taxable capital gain distributions.
     When weighing the decision to buy or sell a security, we strive to balance
     the value of the tax-exempt income, the credit risk of the issuer, and the
     price volatility of the bond.

  Q  What is the Fund's average portfolio maturity and how is it calculated?

  A  While the Fund's average portfolio  maturity is not restricted,  we expect
     it to be greater than 10 years.  To  determine a  security's  maturity for
     purposes of calculating  the Fund's  average  portfolio  maturity,  we may
     estimate  the  expected  time in which the  security's  principal is to be
     paid.  This can be  substantially  shorter than its stated final maturity.
     For more  information  on the method of  calculating  the  Fund's  average
     weighted  portfolio  maturity,  see  INVESTMENT  POLICIES  in  the  Fund's
     Statement of Additional Information.

Florida Tax-Free Money Market Fund

  Q  What is the credit quality of the Fund's investments?

  A  The Fund's  investments  consist of securities meeting the requirements to
     qualify as "eligible  securities"  under the SEC rules applicable to money
     market funds.  In general,  an eligible  security is defined as a security
     that is:

     *   issued  or  guaranteed  by  the  U.S.  Government  or  any  agency  or
         instrumentality  thereof  including  "prerefunded"  and  "escrowed  to
         maturity" tax-exempt securities;

                                     16
<PAGE>
     *   rated  or  subject  to a  guarantee  that  is  rated in one of the two
         highest categories for short-term securities by at least two Nationally
         Recognized Statistical Rating Organizations (NRSROs), or  by one NRSRO
         if the security is rated by only one NRSRO;

     *   unrated but issued by an issuer or guaranteed by a guarantor  that has
         other comparable short-term debt obligations so rated; or

     *   unrated but determined by us to be of comparable quality.

     In addition,  we must consider  whether a particular  investment  presents
     minimal credit risk.

  Q  Who are the Nationally Recognized Statistical Rating Organizations?

  A  Current NRSROs include:

     * Moody's Investors Service, Inc.;
     * Standard & Poor's Ratings Group;
     * Fitch IBCA, Inc.;
     * Duff & Phelps, LLC; and
     * Thompson BankWatch, Inc.

  Q  What happens if the rating of a security is downgraded?

  A  If the  rating  of a  security  is  downgraded  after  purchase,  we  will
     determine whether it is in the best interest of the Fund's shareholders to
     continue to hold the security in the Fund's portfolio.

  Q  Will the Fund always maintain a net asset value of $1 per share?

[SIDE BAR]
     DOLLAR-WEIGHTED  AVERAGE PORTFOLIO MATURITY IS OBTAINED BY MULTIPLYING THE
     DOLLAR  VALUE  OF  EACH  INVESTMENT  BY THE  NUMBER  OF  DAYS  LEFT TO ITS
     MATURITY, THEN ADDING THOSE FIGURES TOGETHER AND DIVIDING THE TOTAL BY THE
     DOLLAR VALUE OF THE FUND'S PORTFOLIO.

  A  While we will  endeavor to maintain a constant  Fund net asset value of $1
     per share,  there is no assurance that we will be able to do so. Remember,
     the shares are neither insured nor guaranteed by the U.S.  Government.  As
     such, the Fund carries some risk.

     For example,  there is always a risk that the issuer of a security held by
     the Fund will fail to pay  interest or  principal  when due. We attempt to
     minimize this credit risk by investing only in securities  rated in one of
     the two highest categories for short-term securities, or, if not rated, of
     comparable  quality,  at the time of purchase.  Additionally,  we will not
     purchase  a security  unless  our  analysts  determine  that the  security
     presents minimal credit risk.

     There is also a risk that  rising  interest  rates will cause the value of
     the Fund's  securities  to decline.  We attempt to minimize  this interest
     risk by limiting  the  maturity  of each  security to 397 days or less and

                                     17
<PAGE>
     maintaining a dollar-weighted  average portfolio  maturity for the Fund of
     90 days or less.

     Finally, there is the possibility that one or more investments in the Fund
     cease to be "eligible securities" resulting in the net asset value ceasing
     to be $1 per share.  For  example,  a guarantor  on a security may fail to
     meet a contractual obligation.

  Q  How are the decisions to buy and sell securities made?

  A  We balance  factors  such as credit  quality and  maturity to purchase the
     best relative value available in the market at any given time. While rare,
     sell decisions are usually based on a change in our credit  analysis or to
     take advantage of an opportunity to reinvest at a higher yield.

For additional  information  about other securities in which we may invest each
Fund's assets, see APPENDIX A on page 31.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
these  Funds.  We are an affiliate of United  Services  Automobile  Association
(USAA), a large, diversified financial services institution.  As of the date of
this  Prospectus,  we had  approximately  $40  billion  in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Funds pursuant to an Advisory Agreement.
We are responsible for managing the Funds' portfolios  (including  placement of
brokerage  orders) and their  business  affairs,  subject to the  authority and
supervision  by the Board of Trustees.  For our  services,  the Funds pay us an
annual fee. This fee, which is accrued daily and paid monthly, is computed as a
percentage of the aggregate average net assets of both Funds combined. This fee
is allocated  between the Funds based on the  relative net assets of each.  The
fee is computed  at one-half of one percent  (.50%) of the first $50 million of
average net assets, two-fifths of one percent (.40%) of that portion of average
net assets over $50 million but not over $100 million,  and three-tenths of one
percent (.30%) of that portion of average net assets in excess of $100 million.
The fees we received  for the fiscal year ended March 31,  1999,  were equal to
 .36% of average net assets for the  Florida  Tax-Free  Income Fund and,  net of
reimbursements,  .35% of  average  net assets for the  Florida  Tax-Free  Money
Market Fund. We also provide  services related to selling the Funds' shares and
receive no compensation for those services.

USING MUTUAL FUNDS IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to pursue the higher yields usually  available in
the long-term bond market,  but you are also concerned about the possible price
swings of the long-term bonds.  You could divide your  investments  between the
Florida  Tax-Free Income Fund and the Florida  Tax-Free Money Market Fund. This
would create a portfolio  with a higher yield than that of the money market and
less  volatility  than that of the long-term  market.  This is just one way you
could combine funds to fit your own risk and reward goals.

III. USAA's Family of Funds

We offer you  another  alternative  with our  asset  strategy  funds  listed in
Appendix C under asset allocation on page 35. These unique mutual funds provide
a  professionally  managed,  diversified  investment  portfolio within a mutual
fund.  Designed for the individual who prefers to delegate the asset allocation
process to an investment  manager,  their  structure  achieves  diversification
across a number of investment categories.

Whether you prefer to create  your own mix of mutual  funds or use a USAA Asset
Strategy  Fund,  the USAA  Family of Funds  provides  a broad  range of choices
covering just about any investor's  investment  objectives.  Our member service
representatives  stand  ready to assist you with your  choices  and to help you
craft a  portfolio  to meet your  needs.  Refer to  APPENDIX C on page 35 for a
complete list of the USAA Family of No-Load Mutual Funds.

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT

You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required to open your initial account. However, after you
open  your  initial  account  with us,  you  will not need to

                                     20
<PAGE>
fill out another  application to open another Fund unless the  registration  is
different.

TAX ID NUMBER

Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE

When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we receive your request in proper form.  Each
Fund's NAV is determined at the close of the regular trading session (generally
4:00 p.m. Eastern Time) of the New York Stock Exchange (NYSE) each day the NYSE
is open.  If we receive  your  request  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  after the NAV per share is  calculated,  the purchase
will be effective on the next business day.

If you plan to  purchase  Fund  shares  with a foreign  check,  we suggest  you
convert your foreign check to U.S.  dollars prior to investment in a Fund. This
will avoid a potential  four- to six-week  delay  in the effective date of your
purchase.  Furthermore,  a bank charge may be assessed in the clearing process,
which will be deducted from the amount of the purchase.

   new account or exchange to another USAA Fund, call for instructions. To open
   an account by phone, the new account must have the same registration as your

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  Payment for redemption of shares purchased by EFT or check is sent
after the EFT or check has  cleared,  which  could  take up to 15 days from the
purchase date. If you are considering redeeming shares soon after purchase, you
should  purchase by bank wire or certified  check to avoid  delay.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital

                                      22
<PAGE>
gains or losses  are based on the  difference  between  your cost  basis in the
shares and the price received upon redemption.

In  addition,  the Funds  may  elect to  suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

HOW TO REDEEM

WRITTEN, FAX, TELEGRAM, OR TELEPHONE

[FAX MACHINE GRAPHIC]
*  Send your written instructions to:
     USAA Shareholder Account Services

Telephone redemption privileges are automatically established when you complete
your application.  The Fund will employ  reasonable  procedures to confirm that
instructions  communicated by telephone are genuine; and if it does not, it may
be liable for any losses due to unauthorized or fraudulent instructions. Before
any  discussion regarding  your account, the following information is obtained:
(1) USAA number and/or account number, (2) the name(s) on the account
registration,  and (3) social security/tax identification number
or  date  of  birth  of  the  registered   account  owner(s)  for  the  account
registration.  Additionally, all telephone communications with you are recorded
and confirmations of account transactions are sent to the address of record. If
you were issued stock  certificates  for your shares,  redemption by telephone,
fax, or telegram is not available.

CHECKWRITING

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

[INVESTOR'S GUIDE GRAPHIC]
Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual fund account and to assist you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

USAA Shareholder  Account Services (SAS), the Funds' transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance,  at the time of assessment,  of less than $2,000.  The fee will reduce
total transfer  agency fees paid by the Fund to SAS.  Accounts  exempt from the
fee include: (1) any account regularly purchasing  additional shares each month
through an automatic  investment  plan;  (2) any account  registered  under the
Uniform  Gifts/Transfers  to Minors Act  (UGMA/UTMA);  (3) all (non-IRA)  money
market fund accounts; (4) any account whose  registered  owner has an aggregate
balance of $50,000 or more invested  in  USAA  mutual  funds;  and (5)  all IRA
accounts (for the first year the account is open).

Fund Rights

Each Fund reserves the right to:

*  reject purchase or exchange orders when in the best interest of the Fund;

*  limit or  discontinue  the offering of shares of the Fund without  notice to
   the shareholders;

*  impose a  redemption  charge  of up to 1% of the net  asset  value of shares
   redeemed if circumstances  indicate a charge is necessary for the protection
   of  remaining  investors  (for  example,  if excessive  market-timing  share
   activity unfairly burdens long-term investors); however, this 1% charge will
   not be imposed upon shareholders  unless authorized by the Board of Trustees
   and the required notice has been given to shareholders;

*  require a  signature  guarantee  for  transactions  or  changes  in  account
   information  in those  instances  where the  appropriateness  of a signature
   authorization  is in  question.  The  Statement  of  Additional  Information
   contains information on acceptable guarantors;

*  redeem an account with a total value of less than $500 of either Fund,  with
   certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered in your state of residence.  Only Florida residents may exchange into a
Florida Fund. After we receive the exchange  orders,  the Funds' transfer agent
will  simultaneously  process  exchange  redemptions and purchases at the share
prices next determined.  The investment  minimums applicable to share purchases
also apply to exchanges.  For federal income tax purposes,  an exchange between
Funds is a taxable event;  and as such, you may realize a capital gain or loss.
Such  capital  gains or losses are based on the  difference  between  your cost
basis in the shares and the price received upon exchange.

The Funds have undertaken certain procedures  regarding telephone  transactions
as described on page 23.

Exchange Limitations, Excessive Trading

To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds).

                                  OUTSTANDING

The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may buy and sell Fund  shares  at the NAV per share  without a
sales  charge.  Each  Fund's  NAV per share is  calculated  at the close of the
regular trading session of the NYSE, which is usually 4:00 p.m. Eastern Time.

Securities of the Florida  Tax-Free Income Fund are valued each business day at
their current market value as determined by a pricing  service  approved by the
Trust's  Board of  Trustees.  Securities  that  cannot be valued by the pricing
service,  and all other  assets,  are valued in good faith at fair value  using
methods  we have  determined  under  the  general  supervision  of the Board of
Trustees.  In addition,  securities  with maturities of 60 days or less and all
securities  of the Florida  Tax-Free  Money Market Fund are stated at amortized
cost, which approximates market value.

                                      25
<PAGE>
For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Funds' Statement of Additional Information.

Dividends and Distributions

Net  investment  income  of each  Fund is  accrued  daily  and paid on the last
business day of the month.  Dividends shall begin accruing on shares  purchased
the day  following  the  effective  date and  shall  continue  to accrue to the
effective date of redemption.  Any net capital gain distribution usually occurs
within 60 days of the March 31 fiscal year end, which would be somewhere around
the end of May. The Funds will make  additional  payments to  shareholders,  if
necessary, to avoid the imposition of any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  The share price
will be the NAV of the  Fund  shares  computed  on the  ex-dividend  date.  Any
capital gain distributions paid by the Florida Tax-Free Income Fund will reduce
the NAV per share by the amount of the  dividend  or  distribution.  You should
consider  carefully  the effects of purchasing  shares of the Florida  Tax-Free
Income Fund shortly before any capital gain distribution.  Although,  in effect
this would be a return of capital, these distributions are subject to taxes. If
you become a resident of a state other than  Florida,  we will mail a check for
proceeds of income dividends to you monthly.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions  in effect as of the date of this  Prospectus.  While we manage  the
Funds so that at least 80% of each  Fund's  annual  income  will be exempt from
federal  income  taxes,  we  may  invest  up to 20% of  the  Funds'  assets  in
securities that generate  income not exempt from federal income taxes.  Because
interest  income may be exempt for  federal  income tax  purposes,  it does not
necessarily  mean that the  interest  income may be exempt  under the income or
other tax laws of any state or local taxing authority.  As discussed earlier on
page 14,  capital gain  distributions  by a Fund may be taxable.  Note that the
Taxpayer  Relief Act of 1997 and the  technical  provisions  adopted by the IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax adviser about your investment.

                                     26
<PAGE>
WITHHOLDING  - Federal law requires each Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

*  fails to furnish the Fund with a correct tax identification number,
*  underreports dividend or interest income, or
*  fails to certify that he or she is not subject to withholding.

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Funds'  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - Each Fund will report  information  to you annually  concerning the
tax status of dividends  and  distributions  for federal  income tax  purposes,
including  the  portion  of the  dividends  constituting  interest  on  private
activity  bonds and the  percentage  and source of  interest  income  earned on
tax-exempt securities held by the Fund during the preceding year.

Florida Taxation

The  following  is  only a  summary  of  some  of  the  important  Florida  tax
considerations  generally  affecting  the Funds and  their  shareholders.  This
discussion  is not intended as a  substitute  for careful  planning.  Potential
investors  in the  Funds  should  consult  their  tax  advisers  with  specific
reference to their own tax situations.

Dividends and distributions  paid by the Funds to individuals who are residents
of  Florida  are not  taxable by  Florida,  because  Florida  does not impose a
personal income tax.  Dividends and  distributions by the Funds will be subject
to  Florida  corporate  income  taxes.  Accordingly,  investors  in the  Funds,
including in particular  corporate  investors who may be subject to the Florida
corporate  income tax,  should  consult  their tax advisers with respect to the
application  of  the  Florida  corporate  income  tax to the  receipt  of  Fund
dividends  and  distributions  and to the  investor's  Florida tax situation in
general.

Florida  imposes  a tax  on  intangible  personal  property  owned  by  Florida
residents.  Prior to July 1, 1999,  shares  similar to shares in the Funds were
exempt from Florida  intangible  personal  property tax if the fund's portfolio
consisted solely of assets exempt from the Florida intangible personal property
tax.  Under this  provision,  the Funds  previously  received a ruling from the
Florida Department of Revenue that if, on the last business day of any calendar
year, the Funds'  investments  consist solely of assets exempt from the Florida
intangible  personal  property  tax,  shares  of the  Funds  owned  by  Florida
residents will be exempt from the Florida  intangible  personal property tax in
the following  year.  Effective July 1, 1999, the Florida  Legislature  revised
this  requirement  so that the Funds'  shares will be exempt if at least ninety
percent of the net asset value of the portfolio of assets  corresponding to the
shares in the Funds is

                                     27
<PAGE>
invested  in  assets  that are  exempt  from the  Florida  intangible  personal
property  tax. The Funds have applied for a ruling from the Florida  Department
of Revenue that if, on the last  business day of any  calendar  year,  at least
ninety percent of the net asset value of the portfolio of assets  corresponding
to shares in the Funds is  invested  in assets  that are  exempt  from the tax,
shares of the Funds owned by Florida  residents will be exempt from the Florida
intangible  personal property tax in the following year. Assets exempt from the
Florida  intangible  personal  property tax include  obligations  issued by the
state of Florida and its  political  subdivisions,  municipalities,  and public
authorities;  obligations  of the U.S.  Government,  its  agencies  and certain
territories and possessions such as Puerto Rico, the Virgin Islands,  and Guam;
and cash.  If shares of the Funds are  subject to Florida  intangible  personal
property  tax,  because less than ninety  percent of the net asset value of the
Funds'  assets on the last  business day of the calendar year consist of assets
exempt from the Florida  intangible  personal property tax, only the portion of
the net asset value of shares of the Funds that is  attributable to obligations
of the U.S. Government will be exempt from taxation.

Year 2000

Like  other  organizations  around  the  world,  the Funds  could be  adversely
affected if the computer  systems used by them,  their  service  providers,  or
companies  in  which  they  invest  do  not  properly   process  and  calculate
information that relates to dates beginning  January 1, 2000, and beyond.  This
situation may occur because for many years computer  programmers  used only two
digits to describe years, such as 98 for 1998. A program written in this manner
may not work when it encounters the year 00. To confront this  situation,  USAA
companies  have spent much  effort and  money;  and we are  confident  that our
critical  systems are essentially  prepared for the Year 2000. In addition,  we
are  actively  assessing  the Year 2000  readiness  of our  service  providers,
partners,  and companies in whose securities we invest.  It is not possible for
us to say that you will  experience no effect from this  situation,  but we can
say  that  we are  making  a  large  effort  to  avoid  ill  effects  upon  our
shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                   APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST EACH FUND'S ASSETS:

VARIABLE RATE SECURITIES

We may invest a Fund's  assets in tax-exempt  securities  that bear interest at
rates which are adjusted periodically to market rates.

*  These  interest  rate  adjustments  can both  raise  and  lower  the  income
   generated by such securities. These changes will have the same effect on the
   income earned by the Fund  depending on the  proportion  of such  securities
   held.

*  Because the interest  rates of variable  rate  securities  are  periodically
   adjusted  to  reflect  current  market  rates,  their  market  value is less
   affected by changes in  prevailing  interest  rates than the market value of
   securities with fixed interest rates.

*  The market value of a variable rate security  usually tends toward par (100%
   of face value) at interest rate adjustment time.

In the case of the Florida  Tax-Free  Money Market Fund only, any variable rate
instrument  with a demand  feature  will be deemed to have a maturity  equal to
either  the date on which the  underlying  principal  amount  may be  recovered
through demand or the next rate  adjustment  date  consistent  with  applicable
regulatory requirements.

PUT BONDS

We may invest a Fund's assets in tax-exempt  securities  (including  securities
with variable  interest  rates) that  may be redeemed or sold back (put) to the
issuer of the security or a third party prior to stated  maturity  (put bonds).
Such  securities  will  normally  trade as if maturity is the earlier put date,
even though stated  maturity is longer.  For the Florida  Tax-Free Income Fund,
maturity  for put  bonds is  deemed  to be the date on  which  the put  becomes
exercisable.  Generally,  maturity for put bonds for the Florida Tax-Free Money
Market Fund is determined as stated under Variable Rate Securities.

ZERO COUPON BONDS

We may invest a Fund's  assets in zero  coupon  bonds.  A zero coupon bond is a
security that is sold at a deep discount from its face value, makes no periodic
interest payments,  and is redeemed at face value when it matures. The lump sum
payment at maturity  increases the price  volatility of the zero coupon bond to
changes in interest rates when compared to a bond that distributes a semiannual
coupon payment.  In calculating  its dividend,  each Fund records as income the
daily amortization of the purchase discount.

SYNTHETIC INSTRUMENTS

We may  invest a Fund's  assets in tender  option  bonds,  bond  receipts,  and
similar synthetic municipal  instruments.  A synthetic instrument is a security
created by combining an intermediate  or long-term  municipal bond with a right
to sell  the  instrument  back to the  remarketer  or  liquidity  provider  for
repurchase  on short  notice.  This right to sell is commonly  referred to as a
tender option.  Usually, the tender option is backed by a conditional guarantee
or letter  of  credit  from a bank or other  financial  institution.  Under its
terms,  the  guarantee may expire if the  municipality  defaults on payments of
interest or

                                      31
<PAGE>
principal on the underlying  bond, if the credit rating of the  municipality is
downgraded,  or if the instrument (or the underlying bond) loses its tax-exempt
treatment.  Synthetic instruments involve structural risks that could adversely
affect  the  value of the  instrument  or could  result  in a Fund  holding  an
instrument for a longer period of time than originally anticipated.

WHEN-ISSUED SECURITIES

We may invest a Fund's assets in new securities offered on a when-issued basis.

*  Delivery  and  payment  take  place  after  the  date of the  commitment  to
   purchase, normally within 45 days. Both price and interest rate are fixed at
   the time of commitment.

*  The Funds do not earn interest on the securities until  settlement,  and the
   market  value  of  the  securities  may  fluctuate   between   purchase  and
   settlement.

*  Such securities can be sold before settlement date.

MUNICIPAL LEASE OBLIGATIONS

We may invest a Fund's assets in a variety of instruments  commonly referred to
as municipal lease obligations, including:

*  Leases,
*  Installment purchase contracts, and
*  Certificates of participation in such leases and contracts.

Certain lease  obligations  contain  "non-appropriation"  clauses which provide
that the municipality  has no obligation to make lease  obligation  payments in
future years unless money is appropriated for such purpose on a yearly basis.

ILLIQUID SECURITIES

We may invest up to 15% of the Florida Tax-Free Income Fund's net assets and up
to 10% of the Florida  Tax-Free  Money Market  Fund's net assets in  securities
that are illiquid.  Illiquid  securities are those  securities  which cannot be
disposed  of in the  ordinary  course  of  business,  seven  days or  less,  at
approximately the same value at which the Fund has valued the securities.

Lease obligations and certain put bonds subject to restrictions on transfer may
be determined to be liquid in accordance with the guidelines established by the
Funds' Board of Trustees.

In determining the liquidity of a lease obligation,  we will consider:  (1) the
frequency  of trades  and quotes  for the lease  obligation;  (2) the number of
dealers  willing to  purchase  or sell the lease  obligation  and the number of
other  potential  purchasers;  (3) dealer  undertakings to make a market in the
lease obligation;  (4) the nature of the marketplace trades, including the time
needed to dispose of the lease obligation, the method of soliciting offers, and
the mechanics of transfer;  (5) whether the lease  obligation is of a size that
will be attractive to institutional investors; (6) whether the lease obligation
contains a  non-appropriation  clause and the likelihood  that the obligor will
fail to make an  appropriation  therefor;  and (7) such  other  factors  as the
Manager may determine to be relevant to such determination.

In determining  the liquidity of put bonds with  restrictions  on transfer,  we
will evaluate the credit  quality of the party (the Put  Provider)  issuing (or
unconditionally  guaranteeing  performance on) the  unconditional put or demand
feature of the put bond.

WHAT ARE EACH FUND'S INVESTMENT
OBJECTIVES AND MAIN STRATEGIES?

Each Fund has a common investment objective of providing Texas investors with a
high level of current interest income that is exempt from federal income taxes.
The Texas  Tax-Free  Money Market Fund has a further  objective  of  preserving
capital and maintaining  liquidity.  Each Fund has separate investment policies
to achieve its objective.

The TEXAS TAX-FREE INCOME FUND invests primarily in long-term, investment-grade
Texas  tax-exempt  securities.  The Fund's  average  dollar-weighted  portfolio
maturity is not restricted, but is expected to be greater than 10 years.

The TEXAS TAX-FREE MONEY MARKET FUND invests in high-quality  Texas  tax-exempt
securities with maturities of 397 days or less.

In view of the risks inherent in all  investments  in  securities,  there is no
assurance that the Funds' objectives will be achieved.  See FUND INVESTMENTS on
page 9 for more information.

MAIN RISKS OF INVESTING IN THESE FUNDS

The two primary  risks of  investing  in these Funds are credit risk and market
risk. As with other mutual  funds,  losing money is also a risk of investing in
these Funds.

*  CREDIT RISK  involves  the  possibility  that a borrower  cannot make timely
   interest and principal payments on its securities.

*  MARKET  RISK  involves  the  possibility  that  the  value  of  each  Fund's
   investments  will decline  because of an increase in interest  rates,  or to
   adverse  changes in supply and demand  for  municipal  securities,  or other
   market factors.

These credit and market risks may be magnified  because each Fund  concentrates
in Texas tax-exempt securities.

IF INTEREST RATES INCREASE:  the yield of each Fund may increase and the market
value of the Texas  Tax-Free  Income  Fund's  securities  will likely  decline,
adversely affecting the net asset value and total return.

IF INTEREST RATES DECREASE:  the yield of each Fund may decrease and the market
value of the Texas Tax-Free Income Fund's securities may increase,  which would
likely increase the Fund's net asset value and total return. The Texas Tax-Free
Money Market Fund's total return may decrease.

Other risks of investing in either Fund include call risk and structural risk.

                                       2
<PAGE>
As you consider an investment in either Fund, you should also take into account
your tolerance for the daily  fluctuations of the financial markets and whether
you can afford to leave your money in the  investment  for long periods of time
to ride out down periods.

An investment in either Fund is not a deposit of USAA Federal  Savings Bank, or
any other  bank,  and is not  insured  or  guaranteed  by the  Federal  Deposit
Insurance  Corporation  or any  other  government  agency.  Although  the Texas
Tax-Free Money Market Fund seeks to preserve the value of your investment at $1
per share, it is possible to lose money by investing in the Fund.

Either  Fund by itself  does not  constitute  a  balanced  investment  program.
Diversifying  your investments may improve your long-run  investment return and
lower the volatility of your overall investment portfolio.

COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE?

Yes, it could.  In fact,  the value of your  investment  in the Texas  Tax-Free
Income Fund will fluctuate with the changing  market values of the  investments
in the Fund. We manage the Texas Tax-Free Money Market Fund in accordance  with
strict Securities and Exchange Commission (SEC) guidelines designed to preserve
the Fund's value at $1 per share, although, of course, we cannot guarantee that
the value will remain at $1 per share.

The value of the  securities  in which the Texas  Tax-Free  Income Fund invests
typically  fluctuates  inversely  with changes in the general level of interest
rates.  Changes in the  creditworthiness of issuers and changes in other market
factors such as the  relative  supply of and demand for  tax-exempt  bonds also
create value  fluctuations.  The bar charts shown below  illustrate  the Funds'
volatility and performance from year to year over the life of the Funds.

TOTAL RETURN

All mutual funds must use the same formula to calculate total return.

[SIDE BAR]
     TOTAL  RETURN   MEASURES  THE  PRICE  CHANGE  IN  A  SHARE   ASSUMING  THE
     REINVESTMENT OF ALL DIVIDEND INCOME AND CAPITAL GAIN DISTRIBUTIONS.

YIELD

All mutual funds must use the same  formulas to calculate  yield and  effective
yield.

[SIDE BAR]
     YIELD IS THE ANNUALIZED  NET INCOME OF THE FUND DURING A SPECIFIED  PERIOD
     AS A PERCENTAGE OF THE FUND'S SHARE PRICE.

[SIDE BAR]
     EFFECTIVE  YIELD  IS  CALCULATED  SIMILAR  TO  THE  YIELD,  HOWEVER,  WHEN
     ANNUALIZED, THE INCOME EARNED IS ASSUMED TO BE REINVESTED.

Texas Tax-Free Income Fund

The Texas Tax-Free  Income Fund may advertise  performance in terms of a 30-day
yield  quotation or a  tax-equivalent  yield.  The Fund's  30-day yield for the
period ended December 31, 1998, was 4.64%.

Texas Tax-Free Money Market Fund

The Texas Tax-Free Money Market Fund typically advertises  performance in terms
of a 7-day yield and effective yield or tax-equivalent  yield and may advertise
total return.  The 7-day yield quotation more closely reflects current earnings
of the Fund  than the total  return  quotation.  The  effective  yield  will be
slightly higher than the yield because of the compounding effect of the assumed
reinvestment. Current yields and effective yields fluctuate daily and will vary
with factors such as interest rates and the quality, length of maturities,  and
type of  investments  in the  portfolio.  The Fund's 7-day yield for the period
ended December 31, 1998, was 3.51%.

You may obtain the most current  yield  information  for either of the Funds by
calling 1-800-531-8777.

TAX-EQUIVALENT YIELD

Investors use  tax-equivalent  yields to compare  taxable and tax-exempt  fixed
income investments using a common yield measure.  The  tax-equivalent  yield is
the  yield  that a fully  taxable  investment  must  generate  to earn the same
"take-home" yield as a tax-exempt investment. The calculation depends upon your
federal  marginal  tax rate and  assumes  that an  investor  can fully  itemize
deductions  on his or her  federal tax return.  The higher  your  marginal  tax
bracket,  the higher will be the tax-equivalent  yield and the more valuable is
the Fund's tax exemption.

                                       6
<PAGE>
For  example,  if you  assume a federal  marginal  tax rate of 36%,  the Funds'
tax-equivalent  yields for the period  ending  December 31,  1998,  would be as
follows:

===============================================================================
                                                           TAX-EQUIVALENT
                                                 YIELD          YIELD
- -------------------------------------------------------------------------------
  Texas Tax-Free Income Fund (30 day)            4.64%          7.25%
  Texas Tax-Free Money Market Fund (7 day)       3.51%          5.48%
===============================================================================

Using the example, to exceed the 30-day yield of the Texas Tax-Free Income Fund
on an after-tax  basis,  you must find a fully taxable  investment  that yields
more than  7.25%.  Likewise,  to exceed the 7-day  yield of the Texas  Tax-Free
Money Market Fund,  you must find a fully taxable  investment  that yields more
than 5.48%.

For more information on calculating  tax-equivalent  yields,  see APPENDIX B on
page 32.

Please  consider  performance  information  in light of the  Funds'  investment
objectives and policies and market conditions during the reported time periods.

Principal Investment Strategies and Risks

  Q  What is each Fund's principal investment strategy?

  A  Each Fund's principal  investment  strategy is to invest the Fund's assets
     primarily  in  securities  issued  by the state of  Texas,  its  political
     subdivisions and  instrumentalities,  and by other governmental  entities,
     if, in the opinion of  counsel,  the  interest  from such  obligations  is
     excluded from gross income for federal income tax purposes.

     Currently,  Texas does not have a personal  state income tax. In the event
     Texas does enact a personal  state  income or similar tax, we will attempt
     to seek a high level of current interest income also exempt from such tax.
     The ability of the Funds to pursue this further policy, of course, will be
     affected by the actual form of such a tax.

     These securities  include municipal debt obligations that have been issued
     by Texas and its political  subdivisions,  and duly constituted  state and
     local authorities and corporations.  We refer to these securities as Texas
     tax-exempt  securities.  Texas  tax-exempt  securities  are issued to fund
     public  infrastructure  projects  such as streets and  highways,  schools,
     water and sewer systems,  hospitals, and airports. They may also be issued
     to  refinance  outstanding  obligations  as well as to  obtain  funds  for
     general operating expenses and for loans to other public  institutions and
     facilities.

     Because the projects  benefit the public,  Congress has granted  exemption
     from  federal  income  taxes for the  interest  income  arising from these
     securities.

  Q  What  types of  tax-exempt  securities  will be  included  in each  Fund's
     portfolio?

  A  Each  Fund's  assets may be invested  in any of the  following  tax-exempt
     securities:

     * general  obligation  bonds,  which are secured by the issuer's pledge of
       its full faith,  credit,  and taxing  power for the payment of principal
       and interest;

     * revenue  bonds,  which  are  payable  from the  revenue  derived  from a
       particular  facility  or class of  facilities  or, in some  cases,  from
       annual appropriations made by the state legislature for the repayment of
       interest and principal or other specific  revenue  source,  but not from
       the general taxing power;

                                       9
<PAGE>
     * lease obligations  backed by the  municipality's  covenant to budget for
       the payments due under the lease obligation;

     * synthetic   instruments,   which  combine  a  municipality's   long-term
       obligation  to  pay  interest  and  principal   with  another   person's
       obligation to repurchase the instrument on short notice; and

     * industrial   development   bonds  issued  by  or  on  behalf  of  public
       authorities to obtain funds for privately-operated facilities.

     As a temporary defensive measure because of market,  economic,  political,
     or other  conditions,  we may invest up to 100% of each  Fund's  assets in
     short-term  securities  whether or not they are exempt from federal income
     tax.  To the  extent  that these  temporary  investments  produce  taxable
     income,  that  income  may  result in that Fund not  fully  achieving  its
     investment  objective  during the time it is in this  temporary  defensive
     posture.

  Q  What are the principal  risks  associated  with  investments in tax-exempt
     securities?

  A  The two principal  risks of investing in tax-exempt  securities are credit
     risk and market risk.

[CAUTION LIGHT GRAPHIC]
     CREDIT  RISK.  Credit  risk is the  possibility  that an issuer of a fixed
     income  security  will  fail  to  make  timely  payments  of  interest  or
     principal.  We attempt to minimize the Funds' credit risks by investing in
     securities  considered at least  investment grade at the time of purchase.
     Nevertheless,  even investment-grade securities are subject to some credit
     risk. In addition,  the ratings of securities  are estimates by the rating
     agencies of the credit quality of the securities. The ratings may not take
     into account every risk related to whether  interest or principal  will be
     repaid on a timely basis.

     When evaluating  potential  investments  for the Funds,  our analysts also
     independently  assess credit risk and its impact on the Funds' portfolios.
     Securities  in the lowest  investment  grade ratings  category  (BBB) have
     speculative  characteristics.  Changes  in  economic  conditions  or other
     circumstances  are more  likely to lead to a weakened  capability  to make
     principal and interest  payments on these  securities than is the case for
     higher-rated securities.

[CAUTION LIGHT GRAPHIC]
     MARKET RISK. As a mutual fund investing in bonds, the Funds are subject to
     the risk that the market value of the bonds will decline because of rising
     interest rates.  Bond prices are linked to the prevailing  market interest
     rates.  In general,  when interest  rates rise,  bond prices fall and when
     interest rates fall, bond prices rise.

                                      10
<PAGE>
     The price  volatility of a bond also depends on its  maturity.  Generally,
     the longer the maturity of a bond, the greater its sensitivity to interest
     rates.  To compensate  investors  for this higher market risk,  bonds with
     longer  maturities  generally  offer higher yields than bonds with shorter
     maturities.

  Q  What other risks are associated with investments in tax-exempt securities?

  A  Two other risks that are applicable to certain  tax-exempt  securities are
     call risk and  structural risk.

[CAUTION LIGHT GRAPHIC]
     CALL RISK.  Many  municipal  bonds may be "called,"  or  redeemed,  by the
     issuer before the stated maturity.  During a period of declining  interest
     rates, an issuer would call, or refinance,  a higher yielding bond for the
     same reason that a homeowner  would  refinance a home  mortgage.  Interest
     rates must drop sufficiently so that the savings more than offset the cost
     of refinancing.

     Intermediate-  and long-term  municipal bonds have the greatest call risk,
     because most municipal  bonds may not be called until after ten years from
     the date of  issue.  The  period  of "call  protection"  may be  longer or
     shorter than ten years,  but regardless,  bonds  purchased  closest to the
     date of issue will have the most call  protection.  Typically,  bonds with
     original maturities of ten years or less are not callable.

     Although  investors  certainly  appreciate  the rise in bond  prices  when
     interest  rates  drop,  falling  interest  rates  create  the  environment
     necessary to "call" the  higher-yielding  bonds from your Fund. When bonds
     are called,  the Fund is impacted in several  ways.  Most likely,  we must
     reinvest the bond-call proceeds at lower interest rates. The Fund's income
     may drop as a result. The Fund may also realize a taxable capital gain.

[CAUTION LIGHT  GRAPHIC]
     STRUCTURAL  RISK.  Some tax-exempt  securities,  referred to as "synthetic
     instruments,"  are created by combining a long-term  municipal bond with a
     right to sell the instrument back to the remarketer or liquidity  provider
     for repurchase on short notice, referred to as a "tender option." Usually,
     the  tender  option is backed by a letter of credit or  similar  guarantee
     from a bank. The guarantee, however, is conditional,  which means that the
     bank is not  required to pay under the  guarantee if there is a default by
     the  municipality  or if  certain  other  events  occur.  These  types  of
     instruments  involve special risks,  referred to as "structural risk." For
     example,  because of the structure of a synthetic  instrument,  there is a
     risk that the  instrument  will lose its  tax-exempt  treatment

                                      11
<PAGE>
     or that we will not be able to  exercise  our tender  option.  We will not
     purchase a synthetic  instrument unless counsel has issued an opinion that
     the instrument is entitled to tax-exempt  treatment.  In addition, we will
     not purchase a synthetic  instrument for the Tax-Exempt  Money Market Fund
     unless we believe  there is only  minimal risk that we will not be able to
     exercise our tender option at all times.

  Q  What percentage of each Fund's assets will be invested in Texas tax-exempt
     securities?

  A  During  normal market  conditions,  at least 80% of each Fund's net assets
     will  consist  of Texas  tax-exempt  securities.  This  policy may only be
     changed by a shareholder vote.

     In addition to Texas tax-exempt  securities,  securities issued by certain
     U.S.  territories and possessions such as Puerto Rico, the Virgin Islands,
     and Guam are exempt from federal  personal  income taxes;  and as such, we
     may  consider  investing  up  to  20%  of  each  Fund's  assets  in  these
     securities.

  Q  Are each Fund's investments diversified in many different issuers?

  A  Each Fund is considered  diversified  under the federal  securities  laws.
     This  means that we will not  invest  more than 5% in any one issuer  with
     respect to 75% of each Fund's assets. With respect to the remaining 25% of
     each  Fund's  assets,  we could  invest  more than 5% in any one, or more,
     issuers.  Purchases  of  securities  issued  or  guaranteed  by  the  U.S.
     Government or its agencies or instrumentalities are not counted toward the
     5%  limitation.  Each Fund,  of  course,  is  concentrated  geographically
     through the purchase of Texas tax-exempt securities.

     With  respect  to  the  Texas  Tax-Free  Money  Market  Fund,  strict  SEC
     guidelines  do not permit us to invest,  with respect to 75% of the Fund's
     assets,  greater than 10% of the Fund's assets in securities  issued by or
     subject to guarantees by the same institution.

     We also may not invest  more than 25% of the Funds'  assets in  securities
     issued  in  connection   with  the  financing  of  projects  with  similar
     characteristics,  such as toll road revenue bonds,  housing revenue bonds,
     or electric power project  revenue bonds,  or in industrial  revenue bonds
     that are based, directly or indirectly,  on the credit of private entities
     of any one industry. However, we reserve the right to invest more than 25%
     of the Funds'  assets in  tax-exempt  industrial  revenue  bonds.  The 25%
     industry  limitation

                                      12
<PAGE>
     does not apply to general  obligation  bonds or bonds that are escrowed in
     U.S. Government securities.

  Q  What are the potential risks  associated with  concentrating  such a large
     portion of each Fund's assets in one state?

[CAUTION LIGHT GRAPHIC]
  A  The Funds are  subject to credit and market  risks,  as  described  above,
     which could be  magnified  by the Funds'  concentration  in Texas  issues.
     Texas  tax-exempt  securities  may be  affected  by  political,  economic,
     regulatory,  or other developments that limit the ability of Texas issuers
     to pay interest or repay  principal  in a timely  manner.  Therefore,  the
     Funds are affected by events within Texas to a much greater  degree than a
     more diversified national fund.

     A particular development may not directly relate to the Funds' investments
     but  nevertheless   might  depress  the  entire  market  for  the  state's
     tax-exempt securities and therefore adversely impact the Funds' valuation.

     An investment in the Texas  Tax-Free Money Market Fund may be riskier than
     an  investment  in other  types  of money  market  funds  because  of this
     concentration.

     The  following  are  examples  of just some of the events that may depress
     valuations for Texas tax-exempt securities for an extended period of time:

     * Changes  in state  laws,  including  voter  referendums,  that  restrict
       revenues or raise costs for issuers.

     * Court  decisions  that affect a category  of  municipal  bonds,  such as
       municipal lease obligations or electric utilities.

     * Natural disasters such as floods, storms,  hurricanes,  droughts, fires,
       or earthquakes.

     * Bankruptcy or financial distress of a prominent  municipal issuer within
       the state.

     * Economic  issues that impact  critical  industries or large employers or
       that weaken real estate prices.

     * Reductions in federal or state financial aid.

     * Imbalance in the supply and demand for the state's municipal securities.

     * Developments  that may  change  the tax  treatment  of Texas  tax-exempt
       securities.

     In addition,  because each Fund invests in securities  backed by banks and
     other  financial  institutions,  changes  in the  credit  quality of these
     institutions could cause losses to a Fund and affect its share price.

                                      13
<PAGE>
     Other considerations  affecting the Funds' investments in Texas tax-exempt
     securities are summarized in the Statement of Additional Information under
     SPECIAL RISK CONSIDERATIONS.

  Q  Will any portion of the distributions from the Funds be subject to federal
     income taxes?

  A  During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from gross income for federal  income tax purposes.  This
     policy may only be  changed  by a  shareholder  vote.  We expect  that any
     taxable interest income distributed will be minimal.

     However,  gains and losses from trading  securities  that occur during the
     normal   course  of   managing  a  fund  may  create  net   capital   gain
     distributions.   The  Internal   Revenue  Code   presently   treats  these
     distributions differently than tax-exempt interest income in the following
     ways:

     * Distributions  of net  short-term  capital gains are taxable as ordinary
       income.

     * Distributions  of net  long-term  capital gains are taxable as long-term
       capital  gains,  regardless of the length of time you have held the Fund
       shares.

     * Both short-term and long-term capital gains are taxable whether received
       in cash or reinvested in additional shares.

  Q  Do the Funds purchase municipal bonds secured by bond insurance?

  A  Yes.  We  may  purchase  municipal  bonds  whose  principal  and  interest
     payments are  guaranteed  by an  insurance  company.  In addition,  we may
     purchase municipal bond insurance with Fund assets when we believe it will
     provide a net economic benefit to the shareholders.

  Q  Will income from the Funds be subject to the federal  alternative  minimum
     tax (AMT) for individuals?

  A  During normal market conditions, at least 80% of each Fund's annual income
     will be excluded from the calculation of the federal  alternative  minimum
     tax  (AMT)  for  individuals.  This  policy  may  only  be  changed  by  a
     shareholder  vote.  Since  inception,  the Funds have not  distributed any
     income that is subject to the federal AMT for  individuals,  and we do not
     intend to invest in  securities  subject to the federal AMT.  However,  of
     course,  changes in  federal  tax laws or other  unforeseen  circumstances
     could result in income subject to the federal AMT for individuals.

Texas Tax-Free Income Fund

  Q  What is the credit quality of the Fund's investments?

  A  Under normal market  conditions,  we will invest the Fund's assets so that
     at least 50% of the total market  value of the  tax-exempt  securities  is
     rated within the three highest  long-term rating  categories (A or higher)
     by Moody's Investors Service,  Inc.  (Moody's),  Standard & Poor's Ratings
     Group  (S&P),  or Fitch IBCA,  Inc.  (Fitch) or in the highest  short-term
     rating  category by Moody's,  S&P, or Fitch. If a security is not rated by
     these  rating  agencies,  we  must  determine  that  the  security  is  of
     equivalent investment quality.

     In no event will we purchase a security for the Fund unless it is rated at
     least  investment   grade  at  the  time  of  purchase.   Investment-grade
     securities are those  securities  rated within the four highest  long-term
     rating  categories  by  Moody's  (Baa or  higher),  S&P,  or Fitch (BBB or
     higher),  or in the two  highest  short-term  rating  categories  by these
     rating agencies.  If unrated by these agencies, we must determine that the
     securities are of equivalent investment quality.

     On  occasion,  we may  purchase a credit  rating  with Fund assets when we
     believe it will provide a net economic benefit to the shareholders.

     You will find a complete  description of the above  tax-exempt  ratings in
     the Fund's Statement of Additional Information.

  Q  What happens if the rating of a security is downgraded to below investment
     grade?

  A  We  will  determine  whether  it is in the  best  interest  of the  Fund's
     shareholders to continue to hold the security in the Fund's portfolio.  If
     downgrades  result in more than 5% of the Fund's net assets being invested
     in securities that are less than  investment-grade  quality,  we will take
     immediate action to reduce the Fund's holdings in such securities to 5% or
     less of the Fund's net assets,  unless otherwise  directed by the Board of
     Trustees.

  Q  How are the decisions to buy and sell securities made?

  A  We manage  tax-exempt  funds based on the common  sense  premise  that our
     investors value tax-exempt income over taxable capital gain distributions.
     When weighing the decision to buy or sell a security, we strive to balance
     the value of the tax-exempt income, the credit risk of the issuer, and the
     price volatility of the bond.

                                     15
<PAGE>
  Q  What is the Fund's average portfolio maturity and how is it calculated?

  A  While the Fund's average portfolio  maturity is not restricted,  we expect
     it to be greater than 10 years.  To  determine a  security's  maturity for
     purposes of calculating  the Fund's  average  portfolio  maturity,  we may
     estimate  the  expected  time in which the  security's  principal is to be
     paid.  This can be  substantially  shorter than its stated final maturity.
     For more  information  on the method of  calculating  the  Fund's  average
     weighted  portfolio  maturity,  see  INVESTMENT  POLICIES  in  the  Fund's
     Statement of Additional Information.

Texas Tax-Free Money Market Fund

  Q  What is the credit quality of the Fund's investments?

  A  The Fund's  investments  consist of securities meeting the requirements to
     qualify as "eligible  securities"  under the SEC rules applicable to money
     market funds.  In general,  an eligible  security is defined as a security
     that is:

     * issued  or  guaranteed   by  the  U.S.   Government  or  any  agency  or
       instrumentality   thereof  including   "prerefunded"  and  "escrowed  to
       maturity" tax-exempt securities;

     * rated or subject to a guarantee  that is rated in one of the two highest
       categories  for  short-term   securities  by  at  least  two  Nationally
       Recognized Statistical Rating Organizations (NRSROs), or by one NRSRO if
       the security is rated by only one NRSRO;

     * unrated but issued by an issuer or  guaranteed  by a guarantor  that has
       other comparable short-term debt obligations so rated; or

     * unrated but determined by us to be of comparable quality.

     In addition,  we must consider  whether a particular  investment  presents
     minimal credit risk.

  Q  Who are the Nationally Recognized Statistical Rating Organizations?

  A  Current NRSROs include:

     * Moody's Investors Service, Inc.;
     * Standard & Poor's Ratings Group;
     * Fitch IBCA, Inc.;

                                     16
<PAGE>
     * Duff & Phelps, LLC; and
     * Thompson BankWatch, Inc.

  Q  What happens if the rating of a security is downgraded?

  A  If the  rating  of a  security  is  downgraded  after  purchase,  we  will
     determine whether it is in the best interest of the Fund's shareholders to
     continue to hold the security in the Fund's portfolio.

  Q  Will the Fund always maintain a net asset value of $1 per share?

[SIDE BAR]
     DOLLAR-WEIGHTED AVERAGE PORTFOLIO MATURITY IS OBTAINED BY MULTIPLYING
     THE DOLLAR VALUE OF EACH INVESTMENT BY THE NUMBER OF DAYS LEFT TO ITS
     MATURITY,  THEN  ADDING THOSE FIGURES TOGETHER AND DIVIDING THE TOTAL
     BY THE DOLLAR VALUE OF THE FUND'S PORTFOLIO.

  A  While we will  endeavor to maintain a constant  Fund net asset value of $1
     per share,  there is no assurance that we will be able to do so. Remember,
     the shares are neither insured nor guaranteed by the U.S.  Government.  As
     such, the Fund carries some risk.

     For example,  there is always a risk that the issuer of a security held by
     the Fund will fail to pay  interest or  principal  when due. We attempt to
     minimize this credit risk by investing only in securities  rated in one of
     the two highest categories for short-term securities, or, if not rated, of
     comparable  quality,  at the time of purchase.  Additionally,  we will not
     purchase  a security  unless  our  analysts  determine  that the  security
     presents minimal credit risk.

     There is also a risk that  rising  interest  rates will cause the value of
     the Fund's  securities  to decline.  We attempt to minimize  this interest
     risk by limiting  the  maturity  of each  security to 397 days or less and
     maintaining a dollar-weighted  average portfolio  maturity for the Fund of
     90 days or less.

     Finally, there is the possibility that one or more investments in the Fund
     cease to be "eligible securities" resulting in the net asset value ceasing
     to be $1 per share.  For  example,  a guarantor  on a security may fail to
     meet a contractual obligation.

  Q  How are the decisions to buy and sell securities made?

  A  We balance  factors  such as credit  quality and  maturity to purchase the
     best relative value available in the market at any given time. While rare,
     sell decisions are usually based on a change in our credit  analysis or to
     take advantage of an opportunity to reinvest at a higher yield.

For additional  information  about other securities in which we may invest each
Fund's assets, see APPENDIX A on page 30.

FUND MANAGEMENT

USAA  Investment  Management  Company serves as the manager and  distributor of
these  Funds.  We are an affiliate of United  Services  Automobile  Association
(USAA), a large, diversified financial services institution.  As of the date of
this  Prospectus,  we had  approximately  $40  billion  in total  assets  under
management.  Our mailing address is 9800  Fredericksburg  Road, San Antonio, TX
78288.

We provide management  services to the Funds pursuant to an Advisory Agreement.
We are responsible for managing the Funds' portfolios  (including  placement of
brokerage  orders) and their  business  affairs,  subject to the  authority and
supervision  by the Board of Trustees.  For our  services,  the Funds pay us an
annual fee. This fee, which is accrued daily and paid monthly, is computed as a
percentage of the aggregate average net assets of both Funds combined. This fee
is allocated  between the Funds based on the  relative net assets of each.  The
fee is computed  at one-half of one percent  (.50%) of the first $50 million of
average net assets, two-fifths of one percent (.40%) of that portion of average
net assets over $50 million but not over $100 million,  and three-tenths of one
percent (.30%) of that portion of average net assets in excess of $100 million.
The  fee we  received  for  the  fiscal  year  ended  March  31,  1999,  net of
reimbursements,  was equal to .13% of average net assets for the Texas Tax-Free
Income Fund.  We waived the advisory  fee for the Texas  Tax-Free  Money Market
Fund. We also provide services related to selling the Funds' shares and receive
no compensation for those services.

Although our officers and employees,  as well as those of the Funds, may engage
in personal securities transactions, they are restricted by the procedures in a
Joint Code of Ethics adopted by the Funds and us.

USING MUTUAL FUNDS IN AN INVESTMENT PROGRAM

I. The Idea Behind Mutual Funds

Mutual funds provide small investors some of the advantages  enjoyed by wealthy
investors.  A  relatively  small  investment  can  buy  part  of a  diversified
portfolio. That portfolio is managed by investment professionals, relieving you
of the  need to make  individual  stock  or bond  selections.  You  also  enjoy
conveniences,  such as daily  pricing,  liquidity,  and in the case of the USAA
Family of Funds, no sales charge. The portfolio, because of its size, has lower
transaction  costs on its trades than most individuals would have. As a result,
you own an investment  that in earlier times would have been  available only to
very wealthy people.

II. Using Funds in an Investment Program

In  choosing a mutual  fund as an  investment  vehicle,  you are giving up some
investment decisions,  but must still make others. The decisions you don't have
to make are those involved with choosing individual securities. We will perform
that function.  In addition, we will arrange for the safekeeping of securities,
auditing the annual financial  statements,  and daily valuation of the Fund, as
well as other functions.

You,  however,  retain  at  least  part of the  responsibility  for an  equally
important  decision.  This decision involves  determining a portfolio of mutual
funds that balances your  investment  goals with your tolerance for risk. It is
likely that this decision may include the use of more than one fund of the USAA
Family of Funds.

For example,  assume you wish to pursue the higher yields usually  available in
the long-term bond market,  but you are also concerned about the possible price
swings of the long-term bonds.  You could divide your  investments  between the
Texas Tax-Free Income Fund and the Texas Tax-Free Money Market Fund. This would
create  a  portfolio with a higher yield than that of the money market and less
volatility  than that of the long-term  market.  This is just one way you could
combine funds to fit your own risk and reward goals.

HOW TO INVEST

Purchase of Shares

OPENING AN ACCOUNT

You may open an account and make an investment  as described  below by mail, in
person,  bank wire,  electronic  funds  transfer  (EFT),  or phone. A complete,
signed application is required to open your initial account. However, after you
open  your  initial  account  with us,  you  will not need to fill out  another
application to open another Fund unless the registration is different.

TAX ID NUMBER

Each shareholder  named on the account must provide a social security number or
tax identification number to avoid possible withholding requirements.

EFFECTIVE DATE

When you make a purchase, your purchase price will be the net asset value (NAV)
per share next  determined  after we receive your request in proper form.  Each
Fund's NAV is determined at the close of the regular trading session (generally
4:00 p.m. Eastern Time) of the New York Stock Exchange (NYSE) each day the NYSE
is open.  If we receive  your  request  and  payment  prior to that time,  your
purchase price will be the NAV per share determined for that day. If we receive
your  request or payment  after the NAV per share is  calculated,  the purchase
will be effective on the next business day.

If you plan to  purchase  Fund  shares  with a foreign  check,  we suggest  you
convert your foreign check to U.S. dollars prior to investment in a Fund.  This
will avoid a potential  four- to six-week  delay in  the effective date of your
purchase. Furthermore, a bank charge may be  assessed  in the clearing process,
which will be deducted from the amount of the purchase.

   new account or exchange to another USAA Fund, call for instructions. To open
   an account by phone, the new account must have the same registration as your

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the
NAV per share is calculated.  Redemptions are effective on the day instructions
are received in a manner as  described  below.  However,  if  instructions  are
received  after  the NAV per share  calculation  (generally  4:00 p.m.  Eastern
Time), redemption will be effective on the next business day.

We will send you your  money  within  seven days  after the  effective  date of
redemption.  Payment for redemption of shares purchased by EFT or check is sent
after the EFT or check has  cleared,  which  could  take up to 15 days from the
purchase date. If you are considering redeeming shares soon after purchase, you
should  purchase by bank wire or certified  check to avoid  delay.  For federal
income tax purposes,  a redemption  is a taxable  event;  and as such,  you may
realize a capital gain or loss.  Such capital  gains or losses are based on the
difference  between your cost basis in the shares and the price  received  upon
redemption.

In  addition,  the Funds  may  elect to  suspend  the  redemption  of shares or
postpone the date of payment in limited circumstances.

HOW TO REDEEM

WRITTEN, FAX, TELEGRAM, OR TELEPHONE

[FAX MACHINE GRAPHIC]
*  Send your written instructions to:
     USAA Shareholder Account Services
     9800 Fredericksburg Road

Telephone redemption privileges are automatically established when you complete
your application.  The Fund will employ  reasonable  procedures to confirm that
instructions  communicated by telephone are genuine; and if it does not, it may
be liable for any losses due to unauthorized or fraudulent

                                      22
<PAGE>
instructions.  Before any  discussion  regarding  your  account,  the following
information is obtained: (1) USAA number and/or account number, (2) the name(s)
on the account registration,  and (3) social security/tax identification number
or  date  of  birth  of  the  registered   account  owner(s)  for  the  account
registration.  Additionally, all telephone communications with you are recorded
and confirmations of account transactions are sent to the address of record. If
you were issued stock  certificates  for your shares,  redemption by telephone,
fax, or telegram is not available.

unpaid.  Because the value of your account  changes daily as dividends  accrue,
you may not write a check to close your account.

IMPORTANT INFORMATION ABOUT PURCHASES AND REDEMPTIONS

Investor's Guide to USAA Mutual Fund Services

[INVESTOR'S GUIDE GRAPHIC]
Upon your initial  investment with us, you will receive the INVESTOR'S GUIDE to
help you get the most out of your USAA mutual fund account and to assist you in
your role as an investor.  In the INVESTOR'S  GUIDE,  you will find  additional
information on purchases,  redemptions,  and methods of payment.  You will also
find in-depth information on automatic investment plans, shareholder statements
and reports, and other useful information.

Account Balance

USAA Shareholder  Account Services (SAS), the Funds' transfer agent, may assess
annually a small balance account fee of $12 to each shareholder  account with a
balance,  at the time of assessment,  of less than $2,000.  The fee will reduce
total transfer  agency fees paid by the Fund to SAS.  Accounts  exempt from the
fee include: (1) any account regularly purchasing  additional shares each month
through an automatic  investment  plan;  (2) any account  registered  under the
Uniform  Gifts/Transfers  to Minors Act  (UGMA/UTMA);  (3) all (non-IRA)  money
market fund accounts; (4) any

                                      23
<PAGE>
account  whose  registered  owner has an  aggregate  balance of $50,000 or more
invested in USAA mutual funds; and (5) all IRA accounts (for the first year the
account is open).

Fund Rights

Each Fund reserves the right to:

*  reject purchase or exchange orders when in the best interest of the Fund;

*  limit or  discontinue  the offering of shares of the Fund without  notice to
   the shareholders;

*  impose a  redemption  charge  of up to 1% of the net  asset  value of shares
   redeemed if circumstances  indicate a charge is necessary for the protection
   of  remaining  investors  (for  example,  if excessive  market-timing  share
   activity unfairly burdens long-term investors); however, this 1% charge will
   not be imposed upon shareholders  unless authorized by the Board of Trustees
   and the required notice has been given to shareholders;

*  require a  signature  guarantee  for  transactions  or  changes  in  account
   information  in those  instances  where the  appropriateness  of a signature
   authorization  is in  question.  The  Statement  of  Additional  Information
   contains information on acceptable guarantors;

*  redeem an account with a total value of less than $500 of either Fund,  with
   certain limitations.

EXCHANGES

Exchange Privilege

The exchange privilege is automatic when you complete your application. You may
exchange  shares  among Funds in the USAA Family of Funds,  provided you do not
hold these shares in stock  certificate  form and the shares to be acquired are
offered in your state of  residence.  Only Texas  residents may exchange into a
Texas Fund.  After we receive the exchange  orders,  the Funds'  transfer agent
will  simultaneously  process  exchange  redemptions and purchases at the share
prices next determined.  The investment  minimums applicable to share purchases
also apply to exchanges.  For federal income tax purposes,  an exchange between
Funds is a taxable event;  and as such, you may realize a capital gain or loss.
Such  capital  gains or losses are based on the  difference  between  your cost
basis in the shares and the price received upon exchange.

The Funds have undertaken certain procedures  regarding telephone  transactions
as described on page 22.

                                      24
<PAGE>
Exchange Limitations, Excessive Trading

To  minimize  Fund costs and to protect the Funds and their  shareholders  from
unfair expense burdens,  the Funds restrict excessive  exchanges.  The limit on
exchanges  out of any Fund in the USAA Family of Funds for each  account is six
per calendar  year (except  there is no  limitation on exchanges out of the Tax
Exempt Short-Term Fund,  Short-Term Bond Fund, or any of the money market funds
in the USAA Family of Funds).

                                  OUTSTANDING

The price at which you  purchase  and  redeem  Fund  shares is equal to the net
asset value (NAV) per share determined on the effective date of the purchase or
redemption.  You may buy and sell Fund  shares  at the NAV per share  without a
sales  charge.  Each  Fund's  NAV per share is  calculated  at the close of the
regular trading session of the NYSE, which is usually 4:00 p.m. Eastern Time.

Securities  of the Texas  Tax-Free  Income Fund are valued each business day at
their current market value as determined by a pricing  service  approved by the
Trust's  Board of  Trustees.  Securities  that  cannot be valued by the pricing
service,  and all other  assets,  are valued in good faith at fair value  using
methods  we have  determined  under  the  general  supervision  of the Board of
Trustees.  In addition,  securities  with maturities of 60 days or less and all
securities  of the Texas  Tax-Free  Money  Market Fund are stated at  amortized
cost, which approximates market value.

For  additional  information  on how  securities  are valued,  see VALUATION OF
SECURITIES in the Funds' Statement of Additional Information.

Dividends and Distributions

Net  investment  income  of each  Fund is  accrued  daily  and paid on the last
business day of the month.  Dividends shall begin accruing on shares  purchased
the day  following  the  effective  date and  shall  continue  to accrue to the
effective date of redemption.  Any net capital gain distribution usually occurs
within 60 days of the March 31 fiscal year end, which would be somewhere around
the end of May. The Funds will make  additional  payments to  shareholders,  if
necessary, to avoid the imposition of any federal income or excise tax.

We  will   automatically   reinvest  all  income  dividends  and  capital  gain
distributions  in the Fund unless you instruct us differently.  The share price
will be the NAV of the  Fund  shares  computed  on the  ex-dividend  date.  Any
capital gain  distributions  paid by the Texas Tax-Free Income Fund will reduce
the NAV per share by the amount of the dividend or distribution. You should

                                      25
<PAGE>
consider  carefully  the  effects of  purchasing  shares of the Texas  Tax-Free
Income Fund shortly before any capital gain distribution.  Although,  in effect
this would be a return of capital, these distributions are subject to taxes. If
you become a resident  of a state  other than  Texas,  we will mail a check for
proceeds of income dividends to you monthly.

We will invest any  dividend  or  distribution  payment  returned to us in your
account at the  then-current NAV per share.  Dividend and  distribution  checks
become  void six months  from the date on the  check.  The amount of the voided
check will be invested in your account at the then-current NAV per share.

Federal Taxes

This tax  information  is quite  general and refers to the  federal  income tax
provisions  in effect as of the date of this  Prospectus.  While we manage  the
Funds so that at least 80% of each  Fund's  annual  income  will be exempt from
federal  income  taxes,  we  may  invest  up to 20% of  the  Funds'  assets  in
securities that generate  income not exempt from federal income taxes.  Because
interest  income may be exempt for  federal  income tax  purposes,  it does not
necessarily  mean that the  interest  income may be exempt  under the income or
other tax laws of any state or local taxing authority.  As discussed earlier on
page 14,  capital gain  distributions  by a Fund may be taxable.  Note that the
Taxpayer  Relief Act of 1997 and the  technical  provisions  adopted by the IRS
Restructuring  and Reform Act of 1998 may  affect the status and  treatment  of
certain  distributions   shareholders  receive  from  the  Fund.  Because  each
investor's tax circumstances are unique and because the tax laws are subject to
change, we recommend that you consult your tax adviser about your investment.

WITHHOLDING  - Federal law requires each Fund to withhold and remit to the U.S.
Treasury a portion of the income dividends and capital gain  distributions  and
proceeds of redemptions paid to any non-corporate shareholder who:

*  fails to furnish the Fund with a correct tax identification number,
*  underreports dividend or interest income, or
*  fails to certify that he or she is not subject to withholding.

To avoid this withholding requirement, you must certify on your application, or
on a separate  Form W-9 supplied by the Funds'  transfer  agent,  that your tax
identification  number is correct and you are not  currently  subject to backup
withholding.

REPORTING - Each Fund will report  information  to you annually  concerning the
tax status of dividends  and  distributions  for federal  income tax  purposes,
including  the  portion  of the  dividends  constituting  interest  on  private
activity  bonds and the  percentage  and source of  interest  income  earned on
tax-exempt securities held by the Fund during the preceding year.

                                      26
<PAGE>
Texas Taxation

Texas  does not  currently  impose an  income  tax on  individuals.  Therefore,
dividends and distributions  paid by the Funds to individuals who are residents
of Texas are not subject to a Texas  personal  income tax. If Texas  eventually
enacts a personal income tax, investors will need to consult with their own tax
advisers with respect to the possible taxation of dividends and distributions.

Texas imposes a franchise tax on  corporations,  limited  liability  companies,
certain banks, limited banking  associations, and savings and loan associations
that do  business  in the  State  or that are  chartered  or  authorized  to do
business in the State.  It is a tax on the privilege of doing  business  within
the State,  measured  by such an entity's  net  taxable  capital and by its net
taxable earned surplus.  Because the Funds are series of a registered  open-end
investment  company organized as a Delaware business trust, they themselves are
not subject to the Texas franchise tax. An investor in the Funds subject to the
Texas franchise tax, however,  must include  distributions it receives from the
Funds in its calculation of net taxable  capital.  All  distributions  from the
Funds that are exempt  from  federal  income tax,  though,  are exempt from the
portion of the Texas franchise tax based on taxable earned surplus.

Year 2000

Like  other  organizations  around  the  world,  the Funds  could be  adversely
affected if the computer  systems used by them,  their  service  providers,  or
companies  in  which  they  invest  do  not  properly   process  and  calculate
information that relates to dates beginning  January 1, 2000, and beyond.  This
situation may occur because for many years computer  programmers  used only two
digits to describe years, such as 98 for 1998. A program written in this manner
may not work when it encounters the year 00. To confront this  situation,  USAA
companies  have spent much  effort and  money;  and we are  confident  that our
critical  systems are essentially  prepared for the Year 2000. In addition,  we
are  actively  assessing  the Year 2000  readiness  of our  service  providers,
partners,  and companies in whose securities we invest.  It is not possible for
us to say that you will  experience no effect from this  situation,  but we can
say  that  we are  making  a  large  effort  to  avoid  ill  effects  upon  our
shareholders.

We do believe you are entitled to know with certainty that we will stand behind
your share balance as of the close of business in 1999. When the market reopens
in 2000,  should any computer problem cause a change in the number of shares in
your account, we will return your account to its proper share balance.

                                  APPENDIX A

THE FOLLOWING ARE  DESCRIPTIONS  OF CERTAIN TYPES OF SECURITIES IN WHICH WE MAY
INVEST EACH FUND'S ASSETS:

VARIABLE RATE SECURITIES

We may invest a Fund's  assets in tax-exempt  securities  that bear interest at
rates which are adjusted periodically to market rates.

*  These  interest  rate  adjustments  can both  raise  and  lower  the  income
   generated by such securities. These changes will have the same effect on the
   income earned by the Fund  depending on the  proportion  of such  securities
   held.
*  Because the interest  rates of variable  rate  securities  are  periodically
   adjusted  to  reflect  current  market  rates,  their  market  value is less
   affected by changes in  prevailing  interest  rates than the market value of
   securities with fixed interest rates.
*  The market value of a variable rate security  usually tends toward par (100%
   of face value) at interest rate adjustment time.

In the case of the Texas  Tax-Free  Money Market Fund only,  any variable  rate
instrument  with a demand  feature  will be deemed to have a maturity  equal to
either  the date on which the  underlying  principal  amount  may be  recovered
through demand or the next rate  adjustment  date  consistent  with  applicable
regulatory requirements.

PUT BONDS

We may invest a Fund's assets in tax-exempt  securities  (including  securities
with variable  interest  rates) that  may be redeemed or sold back (put) to the
issuer of the security or a third party prior to stated  maturity  (put bonds).
Such  securities  will  normally  trade as if maturity is the earlier put date,
even though  stated  maturity is longer.  For the Texas  Tax-Free  Income Fund,
maturity  for put  bonds is  deemed  to be the date on  which  the put  becomes
exercisable.  Generally,  maturity for put bonds for the Texas  Tax-Free  Money
Market Fund is determined as stated under Variable Rate Securities.

ZERO COUPON BONDS

We may invest a Fund's  assets in zero  coupon  bonds.  A zero coupon bond is a
security that is sold at a deep discount from its face value, makes no periodic
interest payments,  and is redeemed at face value when it matures. The lump sum
payment at maturity  increases the price  volatility of the zero coupon bond to
changes in interest rates when compared to a bond that distributes a semiannual
coupon payment.  In calculating  its dividend,  each Fund records as income the
daily amortization of the purchase discount.

SYNTHETIC  INSTRUMENTS

We may  invest a Fund's  assets in tender  option  bonds,  bond  receipts,  and
similar synthetic municipal  instruments.  A synthetic instrument is a security
created by combining an intermediate  or long-term  municipal bond with a right
to sell  the  instrument  back to the  remarketer  or  liquidity  provider  for
repurchase  on short  notice.  This right to sell is commonly  referred to as a
tender option.  Usually, the tender option is backed by a conditional guarantee
or letter  of  credit  from a bank or other  financial  institution.  Under its
terms,  the  guarantee may expire if the  municipality  defaults on payments of
interest or

                                      30
<PAGE>
principal on the underlying  bond, if the credit rating of the  municipality is
downgraded,  or if the instrument (or the underlying bond) loses its tax-exempt
treatment.  Synthetic instruments involve structural risks that could adversely
affect  the  value of the  instrument  or could  result  in a Fund  holding  an
instrument for a longer period of time than originally anticipated.

WHEN-ISSUED SECURITIES

We may invest a Fund's assets in new securities offered on a when-issued basis.

*  Delivery  and  payment  take  place  after  the  date of the  commitment  to
   purchase, normally within 45 days. Both price and interest rate are fixed at
   the time of commitment.
*  The Funds do not earn interest on the securities until  settlement,  and the
   market  value  of  the  securities  may  fluctuate   between   purchase  and
   settlement.
*  Such securities can be sold before settlement date.

MUNICIPAL LEASE OBLIGATIONS

We may invest a Fund's assets in a variety of instruments  commonly referred to
as municipal lease obligations, including:

*  Leases,
*  Installment purchase contracts, and
*  Certificates of participation in such leases and contracts.

Certain lease  obligations  contain  "non-appropriation"  clauses which provide
that the municipality  has no obligation to make lease  obligation  payments in
future years unless money is appropriated for such purpose on a yearly basis.

ILLIQUID SECURITIES

We may invest up to 15% of the Texas  Tax-Free  Income Fund's net assets and up
to 10% of the Texas Tax-Free Money Market Fund's net assets in securities  that
are illiquid. Illiquid securities are those securities which cannot be disposed
of in the ordinary course of business, seven days or less, at approximately the
same value at which the Fund has valued the securities.

Lease obligations and certain put bonds subject to restrictions on transfer may
be determined to be liquid in accordance with the guidelines established by the
Funds' Board of Trustees.

In determining the liquidity of a lease obligation,  we will consider:  (1) the
frequency  of trades  and quotes  for the lease  obligation;  (2) the number of
dealers  willing to  purchase  or sell the lease  obligation  and the number of
other  potential  purchasers;  (3) dealer  undertakings to make a market in the
lease obligation;  (4) the nature of the marketplace trades, including the time
needed to dispose of the lease obligation, the method of soliciting offers, and
the mechanics of transfer;  (5) whether the lease  obligation is of a size that
will be attractive to institutional investors; (6) whether the lease obligation
contains a  non-appropriation  clause and the likelihood  that the obligor will
fail to make an  appropriation  therefor;  and (7) such  other  factors  as the
Manager may determine to be relevant to such determination.

In determining  the liquidity of put bonds with  restrictions  on transfer,  we
will evaluate the credit  quality of the party (the Put  Provider)  issuing (or
unconditionally  guaranteeing  performance on) the  unconditional put or demand
feature of the put bond.

                            VALUATION OF SECURITIES

Shares of each Fund are offered on a  continuing,  best-efforts  basis  through
USAA Investment  Management  Company (IMCO or the Manager).  The offering price
for  shares of each Fund is equal to the  current  net  asset  value  (NAV) per
share.  The NAV per share of each Fund is calculated by adding the value of all
its portfolio  securities  and other assets,  deducting  its  liabilities,  and
dividing by the number of shares outstanding.

     A Fund's NAV per share is  calculated  each day,  Monday  through  Friday,
except days on which the New York Stock Exchange (NYSE) is closed.  The NYSE is
currently  scheduled to be closed on New Year's Day,  Martin  Luther King,  Jr.
Day, Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving,  and Christmas,  and on the preceding Friday or subsequent Monday
when one of these holidays falls on a Saturday or Sunday, respectively.

     The  investments  of the  FLORIDA  TAX-FREE  INCOME  FUND are valued  each
business  day by a  pricing  service  (the  Service)  approved  by the Board of
Trustees.  The Service uses the mean between quoted bid and asked prices or the
last sale price to price  securities  when,  in the Service's  judgment,  these
prices are readily available and are  representative of the securities'  market
values. For many securities, such prices are not readily available. The Service
generally prices these securities based on methods which include  consideration
of yields or prices of tax-exempt  securities of  comparable  quality,  coupon,
maturity and type,  indications  as to values from dealers in  securities,  and
general market conditions.  Securities  purchased with maturities of 60 days or
less are stated at amortized cost which approximates  market value.  Repurchase
agreements are valued at cost. Securities that cannot be valued by the Service,
and all other  assets,  are valued in good faith at fair  value  using  methods
determined  by the  Manager  under  the  general  supervision  of the  Board of
Trustees.

     The value of the FLORIDA TAX-FREE MONEY MARKET FUND'S securities is stated
at amortized  cost which  approximates  market value.  This involves  valuing a
security  at its  cost and  thereafter  assuming  a  constant  amortization  to
maturity of any discount or premium,  regardless  of the impact of  fluctuating
interest  rates.  While this method  provides  certainty in  valuation,  it may
result in periods  during which the value of an  instrument,  as  determined by
amortized  cost,  is higher or lower than the price the Fund would receive upon
the sale of the instrument.

     The  valuation  of the Florida  Tax-Free  Money  Market  Fund's  portfolio
instruments  based upon their amortized cost is subject to the Fund's adherence
to certain procedures and conditions.  Consistent with regulatory requirements,
the Manager will only purchase securities with remaining maturities of 397 days
or less and will maintain a dollar-weighted  average  portfolio  maturity of no
more than 90 days.  The Manager will invest only in  securities  that have been
determined  to present  minimal  credit  risk and that  satisfy the quality and
diversification  requirements  of  applicable  rules  and  regulations  of  the
Securities and Exchange Commission (SEC).

     The Board of Trustees has established procedures designed to stabilize the
Florida  Tax-Free  Money  Market  Fund's  price per share,  as computed for the
purpose of sales and  redemptions,  at $1. There can be no assurance,  however,
that the Fund  will at all  times be able to  maintain  a  constant  $1 NAV per
share. Such procedures  include review of the Fund's holdings at such intervals
as is deemed  appropriate  to determine  whether the Fund's NAV  calculated  by
using  available  market  quotations  deviates  from $1 per share  and,  if so,
whether such deviation may result in material  dilution or is otherwise  unfair
to  existing  shareholders.  In the  event  that it is  determined  that such a
deviation exists,  the Board of Trustees will take such corrective action as it
regards  necessary and appropriate.  Such action may include selling  portfolio
instruments  prior to maturity to realize capital gains or losses or to shorten
average portfolio maturity,  withholding  dividends,  or establishing a NAV per
share by using available market quotations.

                     CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any order to purchase  shares is canceled due to  nonpayment or if the Trust
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (Transfer Agent) will treat the cancellation as a
redemption of shares  purchased,  and you will be responsible for any resulting
loss  incurred  by the  Fund  or the  Manager.  If you are a  shareholder,  the
Transfer Agent can redeem shares from your account(s) as reimbursement  for all
losses.  In addition,  you may be prohibited  or restricted  from making future
purchases  in any of the USAA  Family of Funds.  A $15 fee is  charged  for all
returned items, including checks and electronic funds transfers.

                                       2
<PAGE>
TRANSFER OF SHARES

You may transfer Fund shares to another person by sending written  instructions
to the Transfer  Agent.  The account must be clearly  identified,  and you must
include  the  number  of  shares  to be  transferred,  the  signatures  of  all
registered owners, and all stock certificates, if any, which are the subject of
transfer.  You also need to send written  instructions signed by all registered
owners and supporting documents to change an account registration due to events
such as divorce,  marriage, or death. If a new account needs to be established,
you must complete and return an application to the Transfer Agent.

             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES

The value of your investment at the time of redemption may be more or less than
the cost at  purchase,  depending on the value of the  securities  held in each
Fund's  portfolio.  Requests  for  redemption  that are  subject to any special
conditions  or which  specify an effective  date other than as provided  herein
cannot be accepted. A gain or loss for tax purposes may be realized on the sale
of shares, depending upon the price when redeemed.

     The Board of Trustees may cause the  redemption of an account with a total
value of less than $500 provided (1) the value of the account has been reduced,
for reasons other than market action,  below the minimum initial  investment in
such Fund at the time of the establishment of the account,  (2) the account has
remained below the minimum level for six months, and (3) 60 days' prior written
notice of the proposed redemption has been sent to you. Shares will be redeemed
at the NAV on the date fixed for  redemption  by the Board of Trustees.  Prompt
payment will be made by mail to your last known address.

     The  Trust  reserves  the right to  suspend  the  right of  redemption  or
postpone  the date of  payment  (1) for any  periods  during  which the NYSE is
closed,  (2) when  trading  in the  markets  the  Trust  normally  utilizes  is
restricted, or an emergency exists as determined by the SEC so that disposal of
the  Trust's  investments  or  determination  of  its  NAV  is  not  reasonably
practicable,  or (3) for such other  periods as the SEC by order may permit for
protection of the Trust's shareholders.

     For the mutual  protection  of the investor  and the Funds,  the Trust may
require a signature  guarantee.  If  required,  each  signature  on the account
registration must be guaranteed.  Signature guarantees are acceptable from FDIC
member  banks,  brokers,  dealers,   municipal  securities  dealers,  municipal
securities  brokers,   government  securities  dealers,  government  securities
brokers,  credit unions,  national securities exchanges,  registered securities
associations,   clearing  agencies,  and  savings  associations.   A  signature
guarantee for active duty military  personnel  stationed abroad may be provided
by an officer of the United States Embassy or Consulate, a staff officer of the
Judge Advocate General, or an individual's commanding officer.

REDEMPTION BY CHECK

Shareholders in the Florida  Tax-Free Money Market Fund may request that checks
be issued  for their  account.  Checks  must be  written in amounts of at least
$250.

     Checks issued to  shareholders of the Fund will be sent only to the person
in whose name the account is registered and only to the address of record.  The
checks  must be  manually  signed by the  registered  owner(s)  exactly  as the
account is registered. For joint accounts the signature of either or both joint
owners will be required on the check,  according  to the  election  made on the
signature  card.  You will  continue  to earn  dividends  until the  shares are
redeemed by the presentation of a check.

     When a check is presented to the Transfer Agent for payment,  a sufficient
number of full and  fractional  shares  from your  account  will be redeemed to
cover the amount of the check.  If the account balance is not adequate to cover
the amount of a check, the check will be returned unpaid.  Because the value of
each account changes as dividends are accrued on a daily basis,  checks may not
be used to close an account.

     The  checkwriting   privilege  is  subject  to  the  customary  rules  and
regulations  of State Street Bank and Trust  Company  (State Street Bank or the
Custodian)  governing checking accounts.  There is no charge to you for the use
of the checks or for subsequent reorders of checks.

     The Trust  reserves  the right to assess a  processing  fee  against  your
account for any  redemption  check not  honored by a clearing or paying  agent.
Currently,  this fee is $15 and is subject to change at any time. Some examples
of such dishonor are improper  endorsement,  checks  written for an amount less
than the minimum check amount, and insufficient or uncollectible funds.

                                       3
<PAGE>
     The Trust,  the  Transfer  Agent,  and State  Street Bank each reserve the
right to change or suspend the  checkwriting  privilege  upon 30 days'  written
notice to participating shareholders.

     You may  request  that the  Transfer  Agent stop  payment on a check.  The
Transfer Agent will use its best efforts to execute stop payment  instructions,
but does not guarantee that such efforts will be effective.  The Transfer Agent
will charge you $10 for each stop payment you request.

                                INVESTMENT PLANS

The Trust makes available the following investment plans to shareholders of the
Funds. At the time you sign up for any of the following  investment  plans that
utilize the electronic funds transfer  service,  you will choose the day of the
month  (the  effective  date) on which you  would  like to  regularly  purchase
shares.  When this day falls on a weekend or holiday,  the electronic  transfer
will take place on the last  business day before the  effective  date.  You may
terminate your participation in a plan at any time. Please call the Manager for
details and necessary forms or applications.

AUTOMATIC PURCHASE OF SHARES

INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per month.

DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer  from  a   non-governmental   employer,   an   income-producing
investment, or an account with a participating financial institution.

DIRECT DEPOSIT PROGRAM - The monthly  transfer of certain  federal  benefits to
directly  purchase  shares of a USAA mutual  fund.  Eligible  federal  benefits
include:  Social Security,  Supplemental Security Income, Veterans Compensation
and Pension,  Civil Service  Retirement  Annuity,  and Civil  Service  Survivor
Annuity.

GOVERNMENT  ALLOTMENT - The  transfer of  military  pay by the U.S.  Government
Finance Center for the purchase of USAA mutual fund shares.

AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly transaction minimum of $50.

BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic  funds  transfer to or from a checking or savings  account.  You may
initiate a "buy" or "sell" whenever you choose.

DIRECTED  DIVIDENDS  - If you own  shares  in more than one of the Funds in the
USAA  Family of Funds,  you may  direct  that  dividends  and/or  capital  gain
distributions  earned in one fund be used to purchase shares  automatically  in
another fund.

     Participation in these  systematic  purchase plans allows you to engage in
dollar-cost  averaging.  For additional  information concerning the benefits of
dollar-cost averaging, see APPENDIX C.

SYSTEMATIC WITHDRAWAL PLAN

If you own shares having a NAV of $5,000 or more in a single investment account
(accounts in different  Funds cannot be aggregated for this  purpose),  you may
request  that enough  shares to produce a fixed  amount of money be  liquidated
from the account monthly or quarterly. The amount of each withdrawal must be at
least $50. Using the electronic funds transfer service,  you may choose to have
withdrawals   electronically   deposited  at  your  bank  or  other   financial
institution. You may also elect to have checks mailed to a designated address.

     This plan may be initiated by depositing shares worth at least $5,000 with
the Transfer Agent and by completing a Systematic  Withdrawal Plan application,
which may be requested from the Manager. You may terminate participation in the
plan at any time.  You are not charged  for  withdrawals  under the  Systematic
Withdrawal Plan. The Trust will not bear any expenses in administering the plan
beyond the regular  transfer agent and custodian costs of issuing and redeeming
shares.  The Manager will bear any  additional  expenses of  administering  the
plan.

     Withdrawals  will be made by redeeming full and  fractional  shares on the
date you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

                                       4
<PAGE>
     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.

                              INVESTMENT POLICIES

The sections  captioned  WHAT ARE EACH FUND'S  INVESTMENT  OBJECTIVES  AND MAIN
STRATEGIES?  and FUND  INVESTMENTS in the Prospectus  describe the  fundamental
investment  objective(s) and the investment  policies  applicable to each Fund.
Each Fund's objective(s) cannot be changed without  shareholder  approval.  The
following is provided as additional information.

CALCULATION OF PORTFOLIO WEIGHTED AVERAGE MATURITIES

Weighted  average  maturity  is  derived  by  multiplying  the  value  of  each
investment by the number of days remaining to its maturity,  adding the results
of these  calculations,  and then dividing the total by the value of the Fund's
portfolio.  An obligation's  maturity is typically determined on a stated final
maturity basis, although there are some exceptions to this rule.

     With respect to obligations  held by the Florida  Tax-Free Income Fund, if
it is  probable  that the  issuer of an  instrument  will take  advantage  of a
maturity-shortening device, such as a call, refunding, or redemption provision,
the date on which the instrument will probably be called, refunded, or redeemed
may be considered to be its maturity  date.  Also, the maturities of securities
subject to sinking fund  arrangements are determined on a weighted average life
basis,  which is the average  time for  principal  to be repaid.  The  weighted
average life of these  securities  is likely to be  substantially  shorter than
their stated final maturity. In addition, for purposes of the Fund's investment
policies,  an instrument will be treated as having a maturity  earlier than its
stated  maturity date if the instrument has technical  features such as puts or
demand  features  that,  in the  judgment  of the  Manager,  will result in the
instrument being valued in the market as though it has the earlier maturity.

     The Florida  Tax-Free  Money Market Fund will determine the maturity of an
obligation in its portfolio in accordance  with Rule 2a-7 under the  Investment
Company Act of 1940, as amended (1940 Act).

REPURCHASE AGREEMENTS

Each Fund may invest up to 5% of its net  assets in  repurchase  agreements.  A
repurchase  agreement is a transaction  in which a security is purchased with a
simultaneous  commitment  to sell the security back to the seller (a commercial
bank or recognized securities dealer) at an agreed upon price on an agreed upon
date,  usually not more than seven days from the date of  purchase.  The resale
price  reflects the purchase  price plus an agreed upon market rate of interest
which is unrelated to the coupon rate or maturity of the purchased security.  A
repurchase  agreement  involves the  obligation of the seller to pay the agreed
upon  price,  which  obligation  is in  effect  secured  by  the  value  of the
underlying security. In these transactions,  the securities purchased by a Fund
will have a total value  equal to or in excess of the amount of the  repurchase
obligation and will be held by the Funds' custodian until  repurchased.  If the
seller defaults and the value of the underlying  security declines,  a Fund may
incur a loss and may incur  expenses in selling the  collateral.  If the seller
seeks relief under the bankruptcy  laws, the  disposition of the collateral may
be delayed or limited. Any investments in repurchase  agreements will give rise
to income which will not qualify as  tax-exempt  income when  distributed  by a
Fund.

WHEN-ISSUED SECURITIES

Each  Fund may  invest in new  issues of  tax-exempt  securities  offered  on a
when-issued  basis;  that is, delivery and payment take place after the date of
the commitment to purchase,  normally  within 45 days.  Both price and interest
rate are fixed at the time of commitment. The Funds do not earn interest on the
securities  until  settlement,  and the  market  value  of the  securities  may
fluctuate  between purchase and settlement.  Such securities can be sold before
settlement date.

     Cash or high  quality  liquid debt  securities  equal to the amount of the
when-issued  commitments  are  segregated  at the Fund's  custodian  bank.  The
segregated  securities are valued at market,  and daily adjustments are made to
keep the  value of the cash and  segregated  securities  at least  equal to the
amount of such  commitments by the Fund. On the settlement  date, the Fund will
meet its obligations  from then available cash, sale of segregated  securities,
sale of other securities, or sale of the when-issued securities themselves.

MUNICIPAL LEASE OBLIGATIONS

Each  Fund may  invest in  municipal  lease  obligations  and  certificates  of
participation in such obligations  (collectively,  lease obligations).  A lease
obligation  does not constitute a general  obligation of the

                                       5
<PAGE>
municipality for which the municipality's taxing power is pledged, although the
lease obligation is ordinarily backed by the municipality's  covenant to budget
for the payments due under the lease obligation.

     Certain  lease  obligations  contain   "non-appropriation"  clauses  which
provide  that the  municipality  has no  obligation  to make  lease  obligation
payments in future  years unless  money is  appropriated  for such purpose on a
yearly basis. Although "non-appropriation" lease obligations are secured by the
leased property,  disposition of the property in the event of foreclosure might
prove  difficult.  In  evaluating  a  potential  investment  in  such  a  lease
obligation,  the Manager will consider:  (1) the credit quality of the obligor,
(2) whether the underlying  property is essential to a  governmental  function,
and (3) whether the lease obligation contains covenants prohibiting the obligor
from substituting  similar property if the obligor fails to make appropriations
for the lease obligation.

TEMPORARY DEFENSIVE POLICY

Each Fund may on a temporary basis because of market,  economic,  political, or
other  conditions,  invest up to 100% of its  assets in  short-term  securities
whether  or not they  are  exempt  from  federal  income  taxes.  Such  taxable
securities may consist of obligations of the U.S.  Government,  its agencies or
instrumentalities,  and  repurchase  agreements  secured  by such  instruments;
certificates  of  deposit  of  domestic  banks  having  capital,  surplus,  and
undivided  profits in excess of $100 million;  banker's  acceptances of similar
banks; commercial paper; and other corporate debt obligations.

OTHER POLICIES

Each Fund may lend its  securities  and engage in short sells  against the box.
The Florida Tax-Free Income Fund may also invest in options,  financial futures
contracts,  and options on financial futures contracts.  However,  the Funds do
not intend to engage in any of these  practices  during the coming year without
first supplying further information in the Prospectus.

                            INVESTMENT RESTRICTIONS

The following  investment  restrictions have been adopted by the Trust for each
Fund. These restrictions may not be changed for any given Fund without approval
by the lesser of (1) 67% or more of the voting securities  present at a meeting
of the Fund if more than 50% of the outstanding  voting  securities of the Fund
are  present  or  represented  by  proxy or (2)  more  than  50% of the  Fund's
outstanding voting securities.  The investment  restrictions of one Fund may be
changed without affecting those of the other Fund.

Under the restrictions, neither Fund will:

(1)  with respect to 75% of its total  assets,  purchase the  securities of any
     issuer (except Government Securities,  as such term is defined in the 1940
     Act) if, as a result,  the Fund would own more than 10% of the outstanding
     voting  securities  of such  issuer or the Fund would have more than 5% of
     the value of its total assets  invested in the  securities of such issuer;
     for purposes of this  limitation,  identification  of the "issuer" will be
     based on a determination of the source of assets and revenues committed to
     meeting interest and principal payments of each security;  for purposes of
     this  limitation the state of Florida or other  jurisdictions  and each of
     its   separate   political   subdivisions,   agencies,   authorities   and
     instrumentalities shall be treated as a separate issuer;

(2)  borrow  money,  except  that a Fund may  borrow  money  for  temporary  or
     emergency  purposes in an amount not exceeding 33 1/3% of its total assets
     (including the amount borrowed) less liabilities  (other than borrowings),
     nor will either Fund purchase  securities when its borrowings exceed 5% of
     its total assets;

(3)  purchase any securities which would cause 25% or more of the value of that
     Fund's  total  assets  at the  time of such  purchase  to be  invested  in
     securities  the interest  upon which is derived from  revenues or projects
     with similar  characteristics,  such as toll road revenue  bonds,  housing
     revenue  bonds,  electric power project  revenue  bonds,  or in industrial
     revenue bonds which are based,  directly or  indirectly,  on the credit of
     private  entities  of  any  one  industry;  provided  that  the  foregoing
     limitation  does not apply with respect to  investments  in U.S.  Treasury
     Bills, other obligations issued or guaranteed by the U.S. Government,  its
     agencies and  instrumentalities,  and, in the case of the Florida Tax-Free
     Money Market Fund,  certificates  of deposit and banker's  acceptances  of
     domestic banks;

(4)  issue senior securities, except as permitted under the 1940 Act;

(5)  underwrite  securities of other issuers,  except to the extent that it may
     be deemed to act as a statutory  underwriter  in the  distribution  of any
     restricted securities or not readily marketable securities;

                                       6
<PAGE>
(6)  purchase or sell real estate  unless  acquired as a result of ownership of
     securities or other instruments (but this shall not prevent investments in
     securities secured by real estate or interests therein);

(7)  lend any securities or make any loan if, as a result, more than 33 1/3% of
     its  total  assets  would  be lent to  other  parties,  except  that  this
     limitation does not apply to purchases of debt securities or to repurchase
     agreements; or

(8)  purchase or sell  commodities  or  commodities  contracts  except that the
     Florida  Tax-Free Income Fund may invest in financial  futures  contracts,
     options thereon, and similar instruments.

ADDITIONAL RESTRICTION

The following  restriction is not considered to be a fundamental  policy of the
Funds.  The Board of Trustees may change this  additional  restriction  without
notice to or approval by the shareholders.

     The Florida Tax-Free Income Fund may not invest more than 15% of the value
of its net assets and the  Florida  Tax-Free  Money  Market Fund may not invest
more than 10% of the value of its net assets in illiquid securities  (including
repurchase agreements maturing in more than seven days).

                          SPECIAL RISK CONSIDERATIONS

The information set forth below is derived from official statements prepared in
connection with the issuance of bonds of the state of Florida (the "State") and
other sources that are generally  available to investors.  The  information  is
provided  as  general  information  intended  to  give a brief  and  historical
description and is not intended to indicate future or continuing  trends in the
financial  or other  positions  of the  State or of  local  governmental  units
located  in  the  State.  The  Trust  has  not   independently   verified  this
information.

     THE FLORIDA ECONOMY. Throughout the 1980's, the State's unemployment rate,
generally,  tracked  below that of the nation.  In the  nineties  the trend was
reversed.  Since 1995 the State's unemployment rate has again tracked below the
U.S.  The  State's  unemployment  rate for 1998 was 4.5%,  while  the  national
average was also 4.5%. The State's  unemployment  rate for 1999 is projected to
be 4.2%, while the national average is projected to be 4.6%.

     Personal  income in the State has been  growing  strongly the last several
years  and has  generally  outperformed  both  the  nation  as a whole  and the
Southeast in particular.  The reasons for this are twofold:  first, the State's
population has expanded at a very strong pace; and second,  the State's economy
since the early seventies has diversified in such a way as to provide a broader
economic  base.  From 1992 through 1997,  the State's per capita income rose an
average of 5.0% per year,  while the  national per capita  income  increased an
average of 4.8%.  For 1997,  the  State's  per capita  personal  income rose an
average of 4.0% while the national  per capita  personal  income rose 4.7%.  In
1997, per capita personal income in Florida was $24,795, while the national per
capita personal income was $25,298. The structure of the State's income differs
from  that  of  the  nation  and  the  Southeast.   Because  the  State  has  a
proportionately greater retirement age population,  property income (dividends,
interest and rent) and transfer payments (social security and pension benefits,
among  other  sources of income)  are a  relatively  more  important  source of
income. For example,  Florida's employment income in 1997, represented 60.9% of
total personal income, while the nation's share of total personal income in the
form of wages and  salaries  and  other  labor  benefits  was  71.2%.  Transfer
payments,  such as social  security,  are  occasionally  subject to legislative
change.

     The State's  strong  population  growth is one main reason why its economy
has typically  performed  better than the nation as a whole. In 1980, the State
was ranked seventh among the 50 states with a population of 9.7 million people.
The State has continued to grow since then and as of April 1, 1997 ranks fourth
with an estimated  population of 14.7 million.  Since 1990, the State's average
annual rate of population  increase has been  approximately 1.8% as compared to
an approximately  1.0% average annual increase for the nation as a whole. While
annual growth in the State's population is expected to decline somewhat,  it is
still  expected to grow  approximately  257,000 per year  throughout the 1990s,
however, no assurance can be given that such growth will continue.

     Tourism is one of the State's most important industries.  Approximately 47
million people visited the State in 1997, as reported by the Florida Department
of  Commerce.  By the end of fiscal year  1998-99,  49.7  million  domestic and
international  tourists  are  expected to have  visited  this State.  The State
expects 50.6 million  visitors in 1999-2000.  The State's tourism appears to be
recovering  from the  effects of negative  publicity  regarding  crime  against
tourists in the State.

                                       7
<PAGE>
     The  State  has  it  dynamic  construction   industry,   with  single  and
multi-family  housing starts  accounting for  approximately  9.2% of total U.S.
housing  starts in 1997,  while  the  State's  population  was only 5.5% of the
nation's total population.  The reason for such a dynamic construction industry
was the rapid  growth of the  State's  population.  Since 1985,  total  housing
starts have averaged  approximately 148,000 per year. Total housing starts were
132,813 in 1997, and are projected to be 97,600 in 1998-99.

     The  Florida  economy is  expected  to grow at a moderate  pace,  but will
continue to outperform the U.S. as a whole.  An important  element of Florida's
economic outlook is the construction sector. Multi-family starts have been slow
to  recover in the State from the early  90's  recession,  but are now  showing
stronger  growth.  Overall,  the Florida economy appears to be in line with the
U.S.  economy and is expected to experience  steady growth over the next couple
of years.

     FLORIDA  REVENUES  AND  EXPENDITURES.  Financial  operations  of the State
covering all receipts and expenditures  are maintained  through the use of four
funds--General  Revenue Fund, Trust Funds,  Working Capital Fund and the Budget
Stabilization Fund. In fiscal year 1996-97, the State derived approximately 67%
of its total direct revenues to these funds from state taxes and fees.  Federal
funds and other special revenues  accounted for the remaining  revenues.  Major
sources of tax revenues to the General  Revenue Fund are the sales and use tax,
corporate  income tax,  intangible  personal  property  tax,  beverage tax, and
estate tax, which amounted to 68%, 8%, 4%, 3%, and 3%,  respectively,  of total
General Revenue Fund receipts.  State  expenditures  are categorized for budget
and appropriation purposes by type of fund and spending unit, which are further
subdivided  by line  item.  In fiscal  year  1996-97,  appropriations  from the
General  Revenue  Fund for  education,  health and welfare,  and public  safety
amounted to  approximately  53%, 26% and 14%,  respectively,  of total  General
Revenues.

     The   estimated   General   Revenue  plus   Working   Capital  and  Budget
Stabilization  funds  available  to the State for  fiscal  year  1998-99  total
$19,481.8  million,  an 5.2%  increase  over  1997-98.  Compared  to  effective
appropriations   from  General   Revenues  plus  Working   Capital  and  Budget
Stabilization funds for fiscal year 1998-99 of $18,222.0 million,  this results
in  unencumbered  reserves  estimated at $1,360.7  million at the end of fiscal
year  1998-99.  Estimated  fiscal year  1999-00  General  Revenue  plus Working
Capital and Budget  Stabilization  funds available total $20,133.9  million,  a
3.3% increase over fiscal year 1998-99.

     The sales and use tax is the greatest single source of tax receipts in the
State. For the State fiscal year ended June 30, 1997, receipts from this source
were $12,089 million, an increase of 5.5% from fiscal year 1996-97.  The second
largest  source of state tax receipts is the Motor Fuel Tax.  Preliminary  data
show  collections  from this source in state  fiscal year ending June 30, 1997,
were $2,012  million.  However,  these revenues are almost  entirely  dedicated
trust funds for specific  purposes  and are not  included in the State  General
Revenue Fund.  Alcoholic  beverage tax revenues totalled $447.2 million for the
State  fiscal year ending June 30, 1997.  The receipts of corporate  income tax
for the fiscal year ended June 30, 1997 were $1,362.3  million,  an increase of
17.2% from the previous  fiscal year.  Gross Receipt tax collections for fiscal
year 1996-97 totalled 575.7 million, an increase of 6% over the previous fiscal
year.  Documentary stamp tax collections  totalled $844.2 million during fiscal
year 1996-97,  increasing  8.9% from the previous  fiscal year.  The intangible
personal  property  tax  is  a  tax  on  stocks,  bonds,  notes,   governmental
leaseholds,  certain  limited  partnership  interests,   mortgages,  and  other
obligations  secured by liens on Florida realty, and other intangible  personal
property. Total collections from intangible personal property taxes were $952.4
million  during  fiscal year ending June 30,  1997,  a 6.3%  increase  from the
previous fiscal year. Severance taxes totalled $35.4 million during fiscal year
1997-98,  a decline of  approximately  1% from the  previous  fiscal  year.  In
November,  1986, the voters of the State approved a constitutional amendment to
allow the State to operate a lottery. Fiscal year 1996-97 produced ticket sales
of $2.09 billion of which education received approximately $792.3 million.

     The State  Constitution  does not permit a state or local personal  income
tax. An  amendment  to the State  Constitution  by the electors of the State is
required to impose a personal income tax in the State.

     Since January 1, 1994,  property  valuations  for homestead  property have
been  subject to a growth cap.  Growth in the just  (market)  value of property
qualifying  for the  homestead  exemption is limited to 3% or the change in the
Consumer Price Index,  whichever is less. If the property changes  ownership or
homestead  status,  it is to be  re-valued  at full just  value on the next tax
roll.  Although the impact of the growth cap cannot be determined,  it may have
the  effect  of  causing  local  government  units in the State to rely more on
non-ad  valorem  revenues to meet  operating  and other  requirements  normally
funded with ad valorem tax revenues.

     An amendment to the State Constitution was approved by statewide ballot in
the November 8, 1994,  general  election  which is commonly  referred to as the
"Limitation on State Revenues Amendment." This

                                       8
<PAGE>
amendment  provides that state revenues  collected for any fiscal year shall be
limited to state revenues allowed under the amendment for the prior fiscal year
plus an  adjustment  for  growth.  Growth is defined as an amount  equal to the
average  annual  rate of growth in state  personal  income over the most recent
twenty  quarters times the state  revenues  allowed under the amendment for the
prior fiscal year.  State  revenues  collected for any fiscal year in excess of
this limitation are required to be transferred to the Budget Stabilization Fund
until the fund  reaches  the  maximum  balance  specified  in Section  19(g) of
Article  III of the  State  Constitution,  and  thereafter  is  required  to be
refunded to  taxpayers  as provided by general  law.  The  limitation  on state
revenues  imposed by the  amendment may be increased by the  Legislature,  by a
two-thirds vote of each house.

     The term "state  revenues," as used in the amendment,  means taxes,  fees,
licenses,  and charges for services  imposed by the Legislature on individuals,
businesses,  or agencies  outside state  government.  However,  the term "state
revenues"'  does not  include:  (1)  revenues  that are  necessary  to meet the
requirements  set forth in documents  authorizing  the issuance of bonds by the
State;  (2) revenues  that are used to provide  matching  funds for the federal
Medicaid  program with the exception of the revenues used to support the Public
Medical  Assistance Trust Fund or its successor  program and with the exception
of state matching funds used to fund elective expenses made after July 1, 1994;
(3) proceeds  from the State  lottery  returned as prizes;  (4) receipts of the
Florida  Hurricane  Catastrophe  Fund; (5) balances  carried forward from prior
fiscal years; (6) the proceeds from the sale of goods (e.g.  land,  buildings);
or (7) revenue from taxes, licenses,  fees and charges for services required to
be imposed by any amendment or revision to the State Constitution after July 1,
1994. The amendment took effect on January 1, 1995, and was first applicable to
State fiscal year 1995-96.

     It  should be noted  that  many of the  provisions  of the  amendment  are
ambiguous,  and likely will not be  clarified  until state courts have ruled on
their meanings.  Further,  it is unclear how the Legislature will implement the
language of the amendment and whether such implementing legislation itself will
be the subject of further court interpretation.

     The Fund cannot predict the impact of the amendment on state finances.  To
the extent local  governments  traditionally  receive  revenues  from the State
which are subject to, and limited by, the amendment, the future distribution of
such state revenues may be adversely affected by the amendment.

     According  to the Office of the  Comptroller,  Department  of Banking  and
Finance of the State, as of April, 1999, the State maintains a high bond rating
from Moody's Investors Service (Aa2),  Standard & Poor's Corporation (AA+), and
Fitch IBCA, Inc.(AA) on all of its general obligation bonds.

     Such  ratings  may be revised  and  downgraded  at any time by such rating
agencies. Outstanding general obligation bonds at June 30, 1998 totalled almost
$8.7 billion and were issued to finance capital outlay for educational projects
of both local school districts and state universities, environmental protection
and highway  construction.  The State has issued  over $555  million of general
obligation bonds since July 1, 1998.

                             PORTFOLIO TRANSACTIONS

The  Manager,  pursuant to the  Advisory  Agreement  dated June 25,  1993,  and
subject to the general  control of the Trust's  Board of  Trustees,  places all
orders  for  the  purchase  and  sale  of Fund  securities.  Purchases  of Fund
securities are made either directly from the issuer or from dealers who deal in
tax-exempt  securities.  The Manager may sell Fund securities prior to maturity
if circumstances  warrant and if it believes such disposition is advisable.  In
connection  with  portfolio  transactions  for the Trust,  the Manager seeks to
obtain  the best  available  net price  and most  favorable  execution  for its
orders.  The Manager has no agreement or commitment to place  transactions with
any  broker-dealer  and no regular  formula is used to  allocate  orders to any
broker-dealer.  However,  the Manager may place security orders with brokers or
dealers who furnish  research or other services to the Manager as long as there
is no sacrifice in obtaining the best overall terms available. Payment for such
services  would be generated  only  through  purchase of new issue fixed income
securities.

     Such  research  and  other  services  may  include,  for  example:  advice
concerning  the  value  of  securities,   the  advisability  of  investing  in,
purchasing,  or selling  securities,  and the availability of securities or the
purchasers or sellers of securities;  analyses and reports concerning  issuers,
industries,  securities,  economic factors and trends,  portfolio strategy, and
performance  of  accounts;   and  various  functions  incidental  to  effecting
securities  transactions,  such as clearance  and  settlement.  These  research
services may also include access to research on third party data bases, such as
historical  data on  companies,  financial  statements,  earnings  history  and
estimates and corporate releases; real-time quotes and financial news; research
on specific fixed income securities;  research on international market news and
securities;  and

                                       9
<PAGE>
rating services on companies and industries.  The Manager  continuously reviews
the  performance  of  the  broker-dealers   with  whom  it  places  orders  for
transactions.   The  receipt  of  research  from  broker-dealers  that  execute
transactions  on behalf of the Trust may be useful to the Manager in  rendering
investment  management  services to other clients (including  affiliates of the
Manager),  and conversely,  such research provided by  broker-dealers  who have
executed  transaction  orders on behalf of other  clients  may be useful to the
Manager in carrying out its  obligations  to the Trust.  While such research is
available to and may be used by the Manager in providing  investment  advice to
all its clients (including affiliates of the Manager), not all of such research
may be used by the  Manager  for the benefit of the Trust.  Such  research  and
services  will be in  addition  to and not in lieu  of  research  and  services
provided by the Manager,  and the expenses of the Manager will not  necessarily
be  reduced by the  receipt  of such  supplemental  research.  See THE  TRUST'S
MANAGER.

     On occasions  when the Manager deems the purchase or sale of a security to
be in the best interest of the Trust,  as well as the Manager's  other clients,
the Manager,  to the extent permitted by applicable laws and  regulations,  may
aggregate  such  securities to be sold or purchased for the Trust with those to
be sold or purchased for other  customers in order to obtain best execution and
lower  brokerage  commissions,  if  any.  In  such  event,  allocation  of  the
securities  so  purchased  or sold,  as well as the  expenses  incurred  in the
transaction,  will be made by the Manager in the manner it considers to be most
equitable and consistent with its fiduciary  obligations to all such customers,
including the Trust. In some instances, this procedure may impact the price and
size of the position obtainable for the Trust.

     The  tax-exempt  security  market is typically a "dealer"  market in which
investment  dealers buy and sell bonds for their own accounts,  rather than for
customers,  and although the price may reflect a dealer's mark-up or mark-down,
the Trust pays no brokerage  commissions as such. In addition,  some securities
may be purchased directly from issuers.

PORTFOLIO TURNOVER RATE

The  portfolio  turnover  rate is  computed by  dividing  the dollar  amount of
securities  purchased or sold  (whichever  is smaller) by the average  value of
securities owned during the year.

     The rate of  portfolio  turnover  will not be a limiting  factor  when the
Manager  deems  changes  in  the  Florida   Tax-Free  Income  Fund's  portfolio
appropriate in view of its investment objective. For example, securities may be
sold in anticipation of a rise in interest rates (market  decline) or purchased
in anticipation of a decline in interest rates (market rise) and later sold. In
addition, a security may be sold and another security of comparable quality may
be purchased at approximately  the same time in order to take advantage of what
the Fund believes to be a temporary  disparity in the normal yield relationship
between the two securities.  These yield  disparities may occur for reasons not
directly related to the investment  quality of particular issues or the general
movement of interest rates, such as changes in the overall demand for or supply
of various types of tax-exempt securities.

     For the last two fiscal years the Florida Tax-Free Income Fund's portfolio
turnover rates were as follows:

       1998 . . . . .  27.48%            1999. . . . .  25.28%

     Portfolio  turnover  rates  have  been  calculated   excluding  short-term
variable rate securities,  which are those with put date intervals of less than
one year.

                             DESCRIPTION OF SHARES

The Funds are series of the Trust and are diversified. The Trust is an open-end
management investment company established as a business trust under the laws of
the state of Delaware pursuant to a Master Trust Agreement dated June 21, 1993.
The Trust is  authorized  to issue  shares of  beneficial  interest in separate
portfolios.  Four  such  portfolios  have  been  established,  two of which are
described in this SAI. Under the Master Trust Agreement,  the Board of Trustees
is  authorized to create new  portfolios in addition to those already  existing
without shareholder approval.

     Each  Fund's  assets  and all  income,  earnings,  profits,  and  proceeds
thereof, subject only to the rights of creditors, are specifically allocated to
such Fund. They constitute the underlying  assets of each Fund, are required to
be segregated on the books of account,  and are to be charged with the expenses
of such Fund.  Any general  expenses of the Trust not readily  identifiable  as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to dividends and distributions out of the net income and capital gains
belonging to that Fund when declared by the Board.

                                      10
<PAGE>
     Under the Trust's Master Trust Agreement,  no annual or regular meeting of
shareholders is required. Thus, there will ordinarily be no shareholder meeting
unless  otherwise  required  by the  1940  Act.  Under  certain  circumstances,
however,  shareholders may apply to the Trustees for shareholder information in
order to obtain signatures to request a shareholder meeting. The Trust may fill
vacancies  on the Board or appoint new  Trustees if the result is that at least
two-thirds of the Trustees have still been elected by  shareholders.  Moreover,
pursuant to the Master Trust Agreement,  any Trustee may be removed by the vote
of two-thirds of the outstanding Trust shares and holders of 10% or more of the
outstanding  shares of the  Trust can  require  Trustees  to call a meeting  of
shareholders  for the purpose of voting on the removal of one or more Trustees.
The Trust will assist in communicating to other shareholders about the meeting.
On any matter submitted to the  shareholders,  the holder of each Fund share is
entitled  to one vote per  share  (with  proportionate  voting  for  fractional
shares)  regardless  of the  relative  net asset  values of the Funds'  shares.
However,  on matters  affecting  an  individual  Fund,  a separate  vote of the
shareholders of that Fund is required.  Shareholders of a Fund are not entitled
to vote on any  matter  that does not  affect  that Fund but which  requires  a
separate vote of another Fund.  Shares do not have  cumulative  voting  rights,
which means that holders of more than 50% of the shares voting for the election
of Trustees can elect 100% of the Trust's Board of Trustees, and the holders of
less than 50% of the shares  voting for the  election of  Trustees  will not be
able to elect any person as a Trustee.

     Shareholders of a particular Fund might have the power to elect all of the
Trustees of the Trust because that Fund has a majority of the total outstanding
shares of the  Trust.  When  issued,  each  Fund's  shares  are fully  paid and
nonassessable,  have no  pre-emptive  or  subscription  rights,  and are  fully
transferable. There are no conversion rights.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

TAXATION OF THE FUNDS

Each Fund intends to qualify as a regulated investment company under Subchapter
M of the  Internal  Revenue Code of 1986,  as amended (the Code).  Accordingly,
each  Fund will not be liable  for  federal  income  taxes on its  taxable  net
investment  income and net capital  gains  (capital  gains in excess of capital
losses)  that  are  distributed  to  shareholders,   provided  that  each  Fund
distributes  at  least  90% of its net  investment  income  and net  short-term
capital gain for the taxable year.

     To qualify as a regulated  investment  company,  a Fund must,  among other
things,  (1) derive in each  taxable year at least 90% of its gross income from
dividends,  interest, payments with respect to securities loans, gains from the
sale or other disposition of stock, securities or foreign currencies,  or other
income  derived  with  respect to its  business  of  investing  in such  stock,
securities or currencies (the 90% test) and (2) satisfy certain diversification
requirements  at the  close  of  each  quarter  of  the  Fund's  taxable  year.
Furthermore,  to pay tax-exempt interest income dividends,  at least 50% of the
value of each Fund's  total  assets at the close of each quarter of its taxable
year must consist of  obligations  the interest of which is exempt from federal
income tax. Each Fund intends to satisfy this requirement.

     The Code imposes a nondeductible  4% excise tax on a regulated  investment
company that fails to  distribute  during each calendar year an amount at least
equal  to the sum of (1)  98% of its  taxable  net  investment  income  for the
calendar  year,  (2) 98% of its  capital  gain net income for the  twelve-month
period  ending on October 31, and (3) any prior amounts not  distributed.  Each
Fund intends to make such distributions as are necessary to avoid imposition of
this excise tax.

     For federal income tax purposes,  debt  securities  purchased by the Funds
may be treated as having  original  issue  discount.  Original  issue  discount
represents interest income for federal income tax purposes and can generally be
defined as the  excess of the stated  redemption  price at  maturity  of a debt
obligation over the issue price. Original issue discount is treated for federal
income  tax  purposes  as earned by the  Funds,  whether  or not any  income is
actually received, and therefore is subject to the distribution requirements of
the  Code.  However,   original  issue  discount  with  respect  to  tax-exempt
obligations generally will be excluded from the Funds' taxable income, although
such  discount  will be included in gross  income for  purposes of the 90% test
described  previously.  Original  issue  discount  with  respect to  tax-exempt
securities  is accrued and added to the adjusted  tax basis of such  securities
for purposes of determining  gain or loss upon sale or at maturity.  Generally,
the amount of original  issue discount is determined on the basis of a constant
yield to maturity which takes into account the compounding of accrued interest.
An  investment  in a stripped  bond or stripped  coupon will result in original
issue discount.

                                      11
<PAGE>
     Debt securities may be purchased by the Funds at a market discount. Market
discount  occurs when a security is purchased at a price less than the original
issue price  adjusted for accrued  original issue  discount,  if any. The Funds
intend to defer  recognition of accrued market discount until maturity or other
disposition  of the bond. For securities  purchased at a market  discount,  the
gain realized on disposition  will be treated as taxable ordinary income to the
extent it does not exceed accrued market discount on the bond.

     The Funds may also  purchase  debt  securities  at a premium,  i.e.,  at a
purchase price in excess of face amount. With respect to tax-exempt securities,
the premium must be amortized to the maturity  date but no deduction is allowed
for the premium amortization. The amortized bond premium will reduce the Funds'
adjusted tax basis in the securities.  For taxable securities,  the premium may
be amortized if the Funds so elect. The amortized premium on taxable securities
is first offset against interest received on the securities and then allowed as
a deduction,  and, for  securities  issued after  September  27, 1985,  must be
amortized under an economic accrual method.

TAXATION OF THE SHAREHOLDERS

Taxable  distributions are generally  included in a shareholder's  gross income
for the taxable year in which they are received. Dividends declared in October,
November,  or December  and made  payable to  shareholders  of record in such a
month will be deemed to have been  received on December  31, if a Fund pays the
dividend during the following  January.  It is expected that none of the Funds'
distributions will qualify for the corporate dividends-received deduction.

     To the extent that a Fund's  dividends  distributed  to  shareholders  are
derived from interest  income exempt from federal income tax and are designated
as  "exempt-interest  dividends"  by a Fund,  they  will be  excludable  from a
shareholder's  gross income for federal income tax purposes.  Shareholders  who
are recipients of Social Security benefits should be aware that exempt-interest
dividends received from a Fund are includible in their "modified adjusted gross
income"  for  purposes  of  determining  the  amount  of such  Social  Security
benefits, if any, that are required to be included in their gross income.

     All  distributions of investment income during the year will have the same
percentage designated as tax-exempt.  This method is called the "average annual
method."  Since  the Funds  invest  primarily  in  tax-exempt  securities,  the
percentage will be substantially  the same as the amount actually earned during
any particular distribution period.

     A shareholder of the Florida  Tax-Free  Income Fund should be aware that a
redemption  of shares  (including  any  exchange  into  another USAA Fund) is a
taxable event and, accordingly,  a capital gain or loss may be recognized. If a
shareholder receives an exempt-interest  dividend with respect to any share and
such share has been held for six months or less,  any loss on the redemption or
exchange  will be disallowed  to the extent of such  exempt-interest  dividend.
Similarly,  if a  shareholder  of the Fund receives a  distribution  taxable as
long-term  capital  gain with  respect  to shares  of the Fund and  redeems  or
exchanges  shares before he or she has held them for more than six months,  any
loss on the redemption or exchange (not otherwise disallowed as attributable to
an exempt-interest dividend) will be treated as long-term capital loss.

     The Funds may  invest in  private  activity  bonds.  Interest  on  certain
private  activity  bonds  issued  after  August  7,  1986,  is an  item  of tax
preference for purposes of the federal alternative minimum tax (AMT),  although
the interest  continues to be excludable  from gross income for other purposes.
AMT is a  supplemental  tax  designed to ensure that  taxpayers  pay at least a
minimum  amount of tax on their income,  even if they make  substantial  use of
certain tax deductions and  exclusions  (referred to as tax preference  items).
Interest from private activity bonds is one of the tax preference items that is
added to income from other  sources for the purposes of  determining  whether a
taxpayer  is  subject  to the AMT and the  amount  of any tax to be  paid.  For
corporate investors,  alternative minimum taxable income is increased by 75% of
the amount by which adjusted current earnings (ACE) exceeds alternative minimum
taxable  income  before  the  ACE  adjustment.  For  corporate  taxpayers,  all
tax-exempt  interest is considered in  calculating  the AMT as part of the ACE.
Prospective investors should consult their own tax advisers with respect to the
possible application of the AMT to their tax situation.

     Opinions  relating  to the  validity  of  tax-exempt  securities  and  the
exemption  of  interest  thereon  from  federal  income  tax  are  rendered  by
recognized  bond counsel to the issuers.  Neither the  Manager's nor the Funds'
counsel makes any review of the basis of such opinions.

                                      12

                                FLORIDA TAXATION

TAXATION OF THE FUNDS

If the Funds have tax nexus with Florida,  such as through the location  within
Florida of the Trust or Funds' activities or those of their advisers,  then the
Florida Funds will be subject to Florida corporate income tax. In addition,  if
the Funds'  intangible  assets have a taxable situs in Florida,  then the Funds
will be subject to Florida's intangible personal property tax. The Funds intend
to operate so as not to be subject to Florida taxation.

TAXATION OF THE SHAREHOLDERS

Florida  does not  impose an income tax on  individuals.  Thus,  dividends  and
distributions paid by the Funds to individuals who are residents of Florida are
not  taxable by  Florida.  Florida  imposes an income tax on  corporations  and
similar entities at a rate of 5.5%.  Dividends and  distributions of investment
income and capital gains by the Funds will be subject to the Florida  corporate
income tax.  Accordingly,  investors in the Funds,  including,  in  particular,
investors  who may be subject  to the  Florida  corporate  income  tax,  should
consult  their tax  advisers  with  respect to the  application  of the Florida
corporate income tax to the receipt of Fund dividends and  distributions and to
the investor's Florida tax situation in general.

     Florida  imposes a tax on intangible  personal  property  owned by Florida
residents.  Shares in the Funds  constitute  intangible  personal  property for
purposes of the Florida  intangible  personal  property  tax.  Thus,  unless an
exemption  applies,  shares  in the  Funds  will  be  subject  to  the  Florida
intangible  personal  property tax. Prior to July 1, 1999,  Florida provided an
exemption for shares in an investment  fund if the fund's  portfolio  consisted
solely of assets  exempt from the Florida  intangible  personal  property  tax.
Effective July 1, 1999,  the Florida  Legislature  revised this  requirement so
that the shares in a fund will be exempt if at least ninety  percent of the net
asset value of the portfolio of assets  corresponding to the shares in the fund
is invested in assets  that are exempt  from the  Florida  intangible  personal
property tax. Assets exempt from the Florida  intangible  personal property tax
include   obligations  issued  by  the  state  of  Florida  and  its  political
subdivisions,  municipalities, and public authorities;  obligations of the U.S.
Government,  its agencies,  and certain  territories  and  possessions  such as
Puerto Rico, the Virgin Islands, and Guam; and cash.

     The Funds  previously  received a ruling  from the Florida  Department  of
Revenue  that if, on the last  business day of any  calendar  year,  the Funds'
investments  consist  solely  of  assets  exempt  from the  Florida  intangible
personal  property tax, shares of the Funds owned by Florida  residents will be
exempt from the Florida intangible personal property tax in the following year.
The Funds have applied for a ruling from the Florida Department of Revenue that
if, on the last business day of any calendar  year, at least ninety  percent of
the net asset value of the portfolio of assets  corresponding  to shares in the
Funds is invested  in assets that are exempt from the tax,  shares of the Funds
owned by Florida residents will be exempt from the Florida intangible  personal
property tax in the following  year.  Although  there is no assurance  that the
Florida  Department of Revenue will issue a favorable ruling on this issue, the
Florida Department of Revenue previously issued similar rulings under the prior
law.  If shares of the Funds are  subject to the  Florida  intangible  personal
property  tax,  because less than ninety  percent of the net asset value of the
Funds'  assets on the last  business day of the calendar year consist of assets
exempt from the Florida  intangible  personal property tax, only the portion of
the NAV of a share of the Funds that is attributable to obligations of the U.S.
Government will be exempt from taxation.

- ---------------
(a)  Robert  G.  Davis,  Michael  J.C.  Roth, and  John  W.  Saunders,  Jr. are
     affiliated  with the Trust's  investment adviser,  IMCO, and, accordingly,
     receive no remuneration  from  the Trust  or  any  other  Fund of the USAA
     Family of Funds.

(b)  At March 31, 1999, the USAA Family of Funds  consisted of four  registered
     investment  companies offering 35 individual funds. Each Trustee presently
     serves as a Trustee or  Director  of each  investment  company in the USAA
     Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
     Trustee of USAA Life  Investment  Trust, a registered  investment  company
     advised by IMCO,  consisting  of seven funds  available to the public only
     through the purchase of certain  variable  annuity  contracts and variable
     life insurance policies offered by USAA Life Insurance  Company.  Mr. Roth
     receives no compensation as Trustee of USAA Life Investment Trust.

      All of the above Trustees are also  Trustees/Directors of the other funds
within the USAA  Family of Funds.  No  compensation  is paid by any fund to any
Trustee/Director  who is a  director,  officer,  or  employee  of  IMCO  or its
affiliates.  No  pension or  retirement  benefits  are  accrued as part of fund
expenses.  The Trust  reimburses  certain  expenses of the Trustees who are not
affiliated with the investment adviser.  As  of  May 14, 1999, the officers and
Trustees of the Trust and their  families as a group owned  beneficially  or of
record less than 1% of the outstanding shares of the Trust.

     The Trust knows of no one person who, as of May 14, 1999,  held  of record
or owned beneficially 5% or more of either Fund's shares.

                              THE TRUST'S MANAGER

As described  in the  Prospectus,  USAA  Investment  Management  Company is the
Manager  and  investment   adviser,   providing  services  under  the  Advisory
Agreement.  The Manager, a wholly owned indirect  subsidiary of United Services
Automobile   Association  (USAA),  a  large,   diversified  financial  services
institution, was organized in May 1970 and has served as investment adviser and
underwriter for USAA State Tax-Free Trust from its inception.

                                      16
<PAGE>
     In addition  to  managing  the  Trust's  assets,  the Manager  advises and
manages the investments for USAA and its affiliated  companies as well as those
of USAA Investment  Trust,  USAA Mutual Fund, Inc., USAA Tax Exempt Fund, Inc.,
and USAA Life Investment  Trust. As of the date of this SAI, total assets under
management   by  the  Manager  were   approximately   $40  billion,   of  which
approximately $26 billion were in mutual fund portfolios.

ADVISORY AGREEMENT

Under the  Advisory  Agreement,  the Manager  provides an  investment  program,
carries out the investment  policy,  and manages the portfolio  assets for each
Fund.  The  Manager  is  authorized,  subject  to the  control  of the Board of
Trustees of the Trust, to determine the selection,  amount,  and time to buy or
sell  securities for each Fund. In addition to providing  investment  services,
the  Manager  pays  for  office  space,  facilities,  business  equipment,  and
accounting  services (in addition to those  provided by the  Custodian) for the
Trust.  The Manager  compensates all personnel,  officers,  and Trustees of the
Trust if such persons are also employees of the Manager or its affiliates.  For
these  services under the Advisory  Agreement,  the Trust has agreed to pay the
Manager a fee computed as described  under FUND  MANAGEMENT in the  Prospectus.
Management fees are computed and accrued daily and payable monthly.

     Except for the services and facilities provided by the Manager,  the Funds
pay all other  expenses  incurred in their  operations.  Expenses for which the
Funds  are  responsible  include  taxes  (if  any);  brokerage  commissions  on
portfolio transactions (if any); expenses of issuance and redemption of shares;
charges of transfer agents, custodians, and dividend disbursing agents; cost of
preparing  and  distributing  proxy  material;  costs of printing and engraving
stock   certificates;   auditing  and  legal  expenses;   certain  expenses  of
registering  and  qualifying  shares  for sale;  fees of  Trustees  who are not
interested  persons  (not  affiliated)  of the  Manager;  costs of printing and
mailing the Prospectus, SAI, and periodic reports to existing shareholders; and
any other  charges or fees not  specifically  enumerated.  The Manager pays the
cost of printing and mailing copies of the Prospectus,  the SAI, and reports to
prospective shareholders.

     The Advisory Agreement will remain in effect until June 30, 2000, for each
Fund and will continue in effect from year to year  thereafter for each Fund as
long as it is approved at least  annually by a vote of the  outstanding  voting
securities  of such  Fund  (as  defined  by the  1940  Act) or by the  Board of
Trustees (on behalf of such Fund)  including a majority of the Trustees who are
not  interested  persons of the Manager or (otherwise  than as Trustees) of the
Trust,  at a meeting  called for the  purpose of voting on such  approval.  The
Advisory  Agreement  may be  terminated  at any time by either the Trust or the
Manager on 60 days'  written  notice.  It will  automatically  terminate in the
event of its assignment (as defined in the 1940 Act).

     From time to time the Manager may,  without prior notice to  shareholders,
waive all or any portion of fees or agree to reimburse  expenses  incurred by a
Fund. Any such waiver or reimbursement  may be terminated by the Manager at any
time without prior notice to shareholders.  The Manager has voluntarily  agreed
to limit each Fund's expenses to .50% of its ANA until August 1, 2000, and will
reimburse the Funds for all expenses in excess of the limitations.

     For the last three fiscal years, management fees were as follows:

                                        1997         1998        1999
                                      --------     --------     --------
 Florida Tax-Free Income Fund         $233,603     $437,613     $586,064
 Florida Tax-Free Money Market Fund   $301,693     $323,098     $345,419

     Because the Florida  Tax-Free  Money  Market Funds  expenses  exceeded the
Manager's voluntary expense limitation,  the Manager did not receive management
fees to which it would have been entitled as follows:

                                        1997         1998        1999

 Florida Tax-Free Income Fund         $54,750      $10,032      $  --
 Florida Tax-Free Money Market Fund   $56,434      $20,954      $11,257

UNDERWRITER

The Trust has an  agreement  with the Manager for  exclusive  underwriting  and
distribution  of the Funds'  shares on a continuing  best efforts  basis.  This
agreement  provides that the Manager will receive no fee or other  compensation
for such distribution services.

TRANSFER AGENT

The  Transfer  Agent  performs  transfer  agent  services for the Trust under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity for
shareholders  and the  Trust.  For  its  services  under  the  Transfer  Agency
Agreement,  each Fund pays the Transfer Agent an annual fixed fee of $28.50 per
account. The fee is subject to change at any time.

     The fee to the Transfer Agent includes  processing of all transactions and
correspondence.  Fees are billed on a monthly basis at the rate of  one-twelfth
of the annual fee. In addition,  each Fund pays all  out-of-pocket  expenses of
the  Transfer  Agent and other  expenses  which are  incurred  at the  specific
direction of the Trust.

                        CALCULATION OF PERFORMANCE DATA

Information regarding the total return and yield of each Fund is provided under
COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE? in the Prospectus.
See VALUATION OF SECURITIES herein for a discussion of the manner in which each
Fund's price per share is calculated.

TOTAL RETURN

The Florida Tax-Free Income Fund may advertise  performance in terms of average
annual total return for 1-, 5-, and 10-year periods,  or for such lesser period
as the Fund has been in existence.  Average  annual total return is computed by
finding the average  annual  compounded  rates of return over the periods  that
would  equate the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula:

                                P(1 + T)N = ERV

Where:   P  =  a hypothetical initial payment of $1,000
         T  =  average annual total return
         n  =  number of years
       ERV  =  ending redeemable value of a hypothetical $1,000 payment made at
               the beginning of the 1-, 5-, or  10-year  periods  at the end of
               the year or period

     The  calculation  assumes all charges are deducted from the initial $1,000
payment and assumes all dividends and distributions by such Fund are reinvested
at the price  stated in the  Prospectus  on the  reinvestment  dates during the
period and  includes  all  recurring  fees that are charged to all  shareholder
accounts.

     The date of  commencement  of operations for the Florida  Tax-Free  Income
Fund was  October 1, 1993.  The Fund's  average  annual  total  returns for the
following periods ended March 31, 1999, were:

      1 year..... 5.91%      5 year .....7.84%     Since inception ...5.45%

                                      18
<PAGE>
YIELD

The Florida Tax-Free Income Fund may advertise performance in terms of a 30-day
yield  quotation.  The 30-day  yield  quotation is computed by dividing the net
investment  income per share earned  during the period by the maximum  offering
price  per  share on the last day of the  period,  according  to the  following
formula:

                        Yield = 2[((a-b)/(cd)+1)^6 -1]

Where:   a  =  dividends and interest earned during the period
         b  =  expenses accrued for the period (net of reimbursement)
         c  =  the average  daily number of shares  outstanding  during
               the period that were entitled to receive dividends
         d  =  the maximum offering price per share on the last day of
               the period

     For purposes of the yield  calculation,  interest income is computed based
on the yield to maturity of each debt  obligation  in the Fund's  portfolio and
all recurring charges are recognized.

     The Fund's 30-day yield for the period ended March 31, 1999, was 4.57%.

YIELD - FLORIDA TAX-FREE MONEY MARKET FUND

When the Florida Tax-Free Money Market Fund quotes a current  annualized yield,
it is based on a specified recent seven-calendar-day  period. It is computed by
(1) determining  the net change,  exclusive of capital changes and income other
than  investment  income,  in the value of a hypothetical  preexisting  account
having a balance of one share at the beginning of the period,  (2) dividing the
net change in account value by the value of the account at the beginning of the
base period to obtain the base  return,  then (3)  multiplying  the base period
return by 52.14 (365/7).  The resulting  yield figure is carried to the nearest
hundredth of one percent.

     The calculation includes (1) the value of additional shares purchased with
dividends on the original  share,  and dividends  declared on both the original
share  and  any  such  additional  shares  and  (2)  any  fees  charged  to all
shareholder  accounts,  in  proportion to the length of the base period and the
Fund's average account size.

     The capital changes  excluded from the  calculation  are realized  capital
gains and losses from the sale of securities  and unrealized  appreciation  and
depreciation.  The Fund's  effective  (compounded)  yield will be  computed  by
dividing the seven-day  annualized  yield as defined above by 365,  adding 1 to
the quotient,  raising the sum to the 365th power,  and  subtracting 1 from the
result.

     Current and effective  yields  fluctuate  daily and will vary with factors
such as  interest  rates and the  quality,  length of  maturities,  and type of
investments in the portfolio.

            Yield for 7-day Period ended March 31, 1999, was 2.71%.
       Effective Yield for 7-day Period ended March 31, 1999, was 2.75%.

TAX-EQUIVALENT YIELD

A  tax-exempt  mutual fund may  provide  more  "take-home"  income than a fully
taxable mutual fund after paying taxes.  Calculating a  "tax-equivalent  yield"
means converting a tax-exempt yield to a pretax-equivalent so that a meaningful
comparison can be made between a tax-exempt  municipal fund and a fully taxable
fund. The Florida Tax-Free Money Market Fund may advertise performance in terms
of a  tax-equivalent  yield based on the 7-day yield or effective yield and the
Florida  Tax-Free  Income Fund may advertise  performance  in terms of a 30-day
tax-equivalent yield.

     To calculate a  tax-equivalent  yield,  the Florida investor must know his
Effective  Marginal Tax Rate or EMTR.  Assuming an investor  can fully  itemize
deductions on his or her federal tax return, the EMTR is the sum of the federal
marginal  tax rate and the Florida  Intangibles  Personal  Property  Tax effect
adjusted to reflect  the  deductibility  of the  Intangibles  Tax from  federal
income tax.

     The  computation  of the  Florida  intangible  tax effect is a  multi-step
process.  Since the  intangible  tax is a tax upon assets,  and not income,  an
investor may reduce his intangibles tax liability by choosing  investments that
are exempt from the Florida  Intangibles  Tax.  We have provided a table in the
Prospectus  to  estimate  the  effect  the  intangibles  tax may  have  upon an
investor's EMTR. The Florida  Intangibles  Property Tax effect is determined by
the investor's filing status, individual or joint, and the fair market value of
intangible assets subject to the intangibles tax. The formula is:

  Florida Intangible Tax Effect = Intangible Tax Liability / Intangible Assets

                                      19
<PAGE>
     The  formula  for  computing  the  EMTR  to  compare  with  fully  taxable
securities subject to both federal income and Florida intangible taxes is:

      EMTR = Federal Marginal Tax Rate + [Florida Intangible Tax Effect x
                         (1-Federal Marginal Tax Rate)]

     The tax-equivalent yield is then computed by dividing the tax-exempt yield
of a fund by the complement of the EMTR.  The  complement,  for example,  of an
EMTR of 36.08% is 63.92%, that is (1.00-0.3608= 0.6392).

   Tax-Equivalent Yield = Tax-Exempt Yield / (1-Effective Marginal Tax Rate)

     Based on a  federal  marginal  tax rate of 36% and  intangible  assets  of
$300,000 filing jointly,  the  tax-equivalent  yields for the Florida  Tax-Free
Income and Florida  Tax-Free  Money Market Funds for the period ended March 31,
1999 were 7.15% and 4.24%, respectively.

              APPENDIX A - TAX-EXEMPT SECURITIES AND THEIR RATINGS

TAX-EXEMPT SECURITIES

Tax-exempt  securities  generally include debt obligations issued by states and
their   political   subdivisions,   and  duly   constituted   authorities   and
corporations,  to obtain funds to construct,  repair or improve  various public
facilities such as airports,  bridges, highways,  hospitals,  housing, schools,
streets, and water and sewer works. Tax-exempt securities may also be issued to
refinance  outstanding  obligations  as well as to  obtain  funds  for  general
operating expenses and for loans to other public institutions and facilities.

     The two principal  classifications  of tax-exempt  securities are "general
obligations" and "revenue" or "special tax" bonds. General obligation bonds are
secured by the issuer's  pledge of its full faith,  credit and taxing power for
the payment of principal and interest. Revenue or special tax bonds are payable
only  from  the  revenues  derived  from a  particular  facility  or  class  of
facilities  or, in some cases,  from the proceeds of a special  excise or other
tax, but not from general tax revenues. The Funds may also invest in tax-exempt
private activity bonds,  which in most cases are revenue bonds and generally do
not have the pledge of the credit of the issuer.  The payment of the  principal
and  interest  on such  industrial  revenue  bonds is  dependent  solely on the
ability  of the  user of the  facilities  financed  by the  bonds  to meet  its
financial  obligations and the pledge, if any, of real and personal property so
financed as security for such payment. There are, of course, many variations in
the terms of, and the security underlying,  tax-exempt  securities.  Short-term
obligations  issued by states,  cities,  municipalities or municipal  agencies,
include Tax Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation
Notes, Construction Loan Notes, and Short-Term Notes.

     The yields of tax-exempt securities depend on, among other things, general
money market conditions,  conditions of the tax-exempt bond market, the size of
a particular  offering,  the maturity of the obligation,  and the rating of the
issue. The ratings of Moody's Investors  Service,  Inc.  (Moody's),  Standard &
Poor's Ratings Group (S&P),  Fitch IBCA, Inc. (Fitch),  Duff &  Phelps LLC, and
Thompson  BankWatch,  Inc.  represent  their  opinions  of the  quality  of the
securities rated by them. It should be emphasized that such ratings are general
and are not absolute  standards of quality.  Consequently,  securities with the
same maturity,  coupon, and rating may have different yields,  while securities
of the same  maturity and coupon but with  different  ratings may have the same
yield. It will be the  responsibility of the Manager to appraise  independently
the  fundamental  quality of the  tax-exempt  securities  included  in a Fund's
portfolio.

I.  LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICES, INC.

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

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

                                      20
<PAGE>
A    Bonds which are rated A possess many favorable  investment  attributes and
     are to be considered as  upper-medium-grade  obligations.  Factors  giving
     security to principal and interest are considered  adequate,  but elements
     may be present which suggest a  susceptibility  to impairment  sometime in
     the future.

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

NOTE:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

STANDARD & POOR'S RATINGS GROUP

AAA  An  obligation  rated AAA has the  highest  rating  assigned by Standard &
     Poor's.  The obligor's  capacity to meet its  financial  commitment on the
     obligation is extremely strong.

AA   An obligation rated AA differs from the highest rated issues only in small
     degree.  The obligor's  capacity to meet its  financial  commitment on the
     obligation is VERY STRONG.

A    An obligation  rated A is somewhat more susceptible to the adverse effects
     of changes in  circumstances  and economic  conditions than obligations in
     higher  rated  categories.  However,  the  obligor's  capacity to meet its
     financial commitment on the obligation is still STRONG.

BBB  An  obligation  rated BBB exhibits  adequate  capacity to pay interest and
     repay  principal.   However,   adverse  economic  conditions  or  changing
     circumstances  are  more  likely  to lead to a  weakened  capacity  of the
     obligor to meet its financial commitment on the obligation.

PLUS  (+) OR MINUS  (-):  THE  RATINGS  FROM AA TO BBB MAY BE  MODIFIED  BY THE
ADDITION  OF A PLUS OR MINUS SIGN TO SHOW  RELATIVE  STANDING  WITHIN THE MAJOR
RATING CATEGORIES.

FITCH IBCA, INC.

AAA  Highest credit  quality.  "AAA" ratings  denote the lowest  expectation of
     credit  risk.  They  are  assigned  only in case of  exceptionally  strong
     capacity for timely  payment of financial  commitments.  This  capacity is
     highly unlikely to be adversely affected by foreseeable events.

AA   Very high credit  quality.  "AA" ratings denote a very low  expectation of
     credit risk.  They  indicate  very strong  capacity for timely  payment of
     financial  commitments.  This capacity is not significantly  vulnerable to
     foreseeable events.

A    High credit quality.  "A" ratings denote a low expectation of credit risk.
     The capacity for timely  payment of financial  commitments  is  considered
     strong. This capacity may, nevertheless,  be more vulnerable to changes in
     circumstances  or in  economic  conditions  than is the  case  for  higher
     ratings.

BBB  Good credit quality.  "BBB" ratings indicate that there is currently a low
     expectation  of credit risk.  The capacity for timely payment of financial
     commitments is considered  adequate,  but adverse changes in circumstances
     and in economic  conditions are more likely to impair this capacity.  This
     is the lowest investment-grade category.

PLUS AND MINUS  SIGNS ARE USED WITH A RATING  SYMBOL TO INDICATE  THE  RELATIVE
POSITION OF A CREDIT WITHIN THE RATING CATEGORY. PLUS AND MINUS SIGNS, HOWEVER,
ARE NOT USED IN THE AAA CATEGORY.

DUFF & PHELPS, LLC

AAA  Highest  credit  quality.  The risk  factors  are  negligible,  being only
     slightly more than for risk-free U.S. Treasury debt.

AA   High credit quality. Protection factors are strong. Risk is modest but may
     vary slightly from time to time because of economic conditions.

A    Protection  factors are average but  adequate.  However,  risk factors are
     more variable and greater in periods of economic stress.

BBB  Below  average  protection  factors but still  considered  sufficient  for
     prudent  investment.  Considerable  variability  in risk  during  economic
     cycles.

2. SHORT-TERM DEBT RATINGS:

MOODY'S STATE AND TAX-EXEMPT NOTES

MIG-1/VMIG1  This  designation  denotes best quality.  There is present  strong
             protection by established cash flows,  superior liquidity support,
             or demonstrated broad-based access to the market for refinancing.

MIG-2/VMIG2  This designation  denotes high quality.  Margins of protection are
             ample although not so large as in the preceding group.

MOODY'S COMMERCIAL PAPER

Prime-1  Issuers rated  Prime-1 (or  supporting  institutions)  have a superior
         ability for  repayment of senior  short-term  promissory  obligations.
         Prime-1 repayment capacity will normally be evidenced by the following
         characteristics:

         * Leading market positions in well-established industries.
         * High rates of return on funds employed.
         * Conservative  capitalization  structures  with moderate  reliance on
           debt and ample asset protection.
         * Broad  margins in earning  coverage of fixed  financial  charges and
           high internal cash generation.
         * Well-established  access to a range of financial markets and assured
           sources of alternate liquidity.

Prime-2  Issuers  rated  Prime-2  (or  supporting  institutions)  have a strong
         ability for  repayment of senior  short-term  promissory  obligations.
         This will normally be evidenced by many of the  characteristics  cited
         above but to a lesser  degree.  Earnings  trends and coverage  ratios,
         while

         sound,   may   be   more   subject   to   variation.    Capitalization
         characteristics,  while  still  appropriate,  may be more  affected by
         external conditions. Ample alternate liquidity is maintained.

S&P TAX-EXEMPT NOTES

SP-1 Strong  capacity to pay  principal  and  interest.  Issues  determined  to
     possess very strong characteristics are given a plus (+) designation.

SP-2 Satisfactory   capacity  to  pay  principal   and   interest,   with  some
     vulnerability  to adverse  financial and economic changes over the term of
     the notes.

S&P COMMERCIAL PAPER

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

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

FITCH'S COMMERCIAL PAPER, CERTIFICATES OF DEPOSIT AND TAX-EXEMPT NOTES

F1   Highest  credit  quality.  Indicates  the  strongest  capacity  for timely
     payment  of  financial  commitments;  may have an added "+" to denote  any
     exceptionally strong credit features.

F2   Good  credit  quality.  A  satisfactory  capacity  for  timely  payment of
     financial commitments,  but the margin of safety is not as great as in the
     case of the higher ratings.

F3   Fair  credit  quality.  The  capacity  for  timely  payment  of  financial
     commitments is adequate;  however,  near-term adverse changes could result
     in a reduction to non-investment grade.

DUFF & PHELPS COMMERCIAL PAPER

D-1+ Highest  certainty  of timely  payment.  Short-term  liquidity,  including
     internal operating factors and/or access to alternative  sources of funds,
     is  outstanding,   and  safety  is  just  below  risk-free  U.S.  Treasury
     short-term obligations.

D-1  Very high certainty of timely payment. Liquidity factors are excellent and
     supported by good fundamental protection factors. Risk factors are minor.

D-1- High  certainty  of timely  payment.  Liquidity  factors  are  strong  and
     supported by good fundamental  protection  factors.  Risk factors are very
     small.

D-2  Good  certainty  of  timely   payment.   Liquidity   factors  and  company
     fundamentals  are sound.  Although ongoing funding needs may enlarge total
     financing  requirements,  access to capital  markets is good. Risk factors
     are small.

                                      22
<PAGE>
THOMPSON BANKWATCH, INC.

TBW-1 The highest category; indicates a very high likelihood that principal and
      interest will be paid on a timely basis.

TBW-2 The second highest category;  while the degree of safety regarding timely
      repayment of principal  and  interest is strong,  the relative  degree of
      safety is not as high as for issues rated TBW-1.

TBW-3 The lowest investment-grade category; indicates that while the obligation
      is more susceptible to adverse  developments (both internal and external)
      than those with higher  ratings,  the capacity to service  principal  and
      interest in a timely fashion is considered adequate.

                       APPENDIX C - DOLLAR-COST AVERAGING

Dollar-cost  averaging is a systematic  investing method,  which can be used by
investors as a disciplined technique for investing.  A fixed amount of money is
invested in a security (such as a stock or mutual fund) on a regular basis over
a period of time,  regardless  of whether  securities  markets are moving up or
down.

     This  practice  reduces  average  share costs to the investor who acquires
more shares in periods of lower  securities  prices and fewer shares in periods
of higher prices.

     While  dollar-cost  averaging does not assure a profit or protect  against
loss in declining markets, this investment strategy is an effective way to help
calm the effect of fluctuations in the financial markets.  Systematic investing
involves  continuous  investment in securities  regardless of fluctuating price
levels of such securities. Investors should consider their financial ability to
continue purchases through periods of low and high price levels.

     As the following chart  illustrates,  dollar-cost  averaging tends to keep
the overall cost of shares lower.  This example is for  illustration  only, and
different trends would result in different average costs.

                            VALUATION OF SECURITIES

Shares of each Fund are offered on a  continuing,  best-efforts  basis  through
USAA Investment  Management  Company (IMCO or the Manager).  The offering price
for  shares of each Fund is equal to the  current  net  asset  value  (NAV) per
share.  The NAV per share of each Fund is calculated by adding the value of all
its portfolio  securities  and other assets,  deducting  its  liabilities,  and
dividing by the number of shares outstanding.

     A Fund's NAV per share is  calculated  each day,  Monday  through  Friday,
except days on which the New York Stock Exchange (NYSE) is closed.  The NYSE is
currently  scheduled to be closed on New Year's Day,  Martin  Luther King,  Jr.
Day, Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving,  and Christmas,  and on the preceding Friday or subsequent Monday
when one of these holidays falls on a Saturday or Sunday, respectively.

     The investments of the TEXAS TAX-FREE INCOME FUND are valued each business
day by a pricing service (the Service)  approved by the Board of Trustees.  The
Service  uses the mean  between  quoted  bid and asked  prices or the last sale
price to price  securities  when, in the Service's  judgment,  these prices are
readily available and are  representative of the securities' market values. For
many securities,  such prices are not readily available.  The Service generally
prices these securities based on methods which include  consideration of yields
or prices of tax-exempt securities of comparable quality,  coupon, maturity and
type,  indications as to values from dealers in securities,  and general market
conditions.  Securities purchased with maturities of 60 days or less are stated
at amortized cost which approximates  market value.  Repurchase  agreements are
valued at cost.  Securities that cannot be valued by the Service, and all other
assets,  are valued in good faith at fair value using methods determined by the
Manager under the general supervision of the Board of Trustees.

     The value of the TEXAS TAX-FREE  MONEY MARKET FUND'S  securities is stated
at amortized  cost which  approximates  market value.  This involves  valuing a
security  at its  cost and  thereafter  assuming  a  constant  amortization  to
maturity of any discount or premium,  regardless  of the impact of  fluctuating
interest  rates.  While this method  provides  certainty in  valuation,  it may
result in periods  during which the value of an  instrument,  as  determined by
amortized  cost,  is higher or lower than the price the Fund would receive upon
the sale of the instrument.

     The  valuation  of  the  Texas  Tax-Free  Money  Market  Fund's  portfolio
instruments  based upon their amortized cost is subject to the Fund's adherence
to certain procedures and conditions.  Consistent with regulatory requirements,
the Manager will only purchase securities with remaining maturities of 397 days
or less and will maintain a dollar-weighted  average  portfolio  maturity of no
more than 90 days.  The Manager will invest only in  securities  that have been
determined  to present  minimal  credit  risk and that  satisfy the quality and
diversification  requirements  of  applicable  rules  and  regulations  of  the
Securities and Exchange Commission (SEC).

     The Board of Trustees has established procedures designed to stabilize the
Texas Tax-Free Money Market Fund's price per share, as computed for the purpose
of sales and redemptions,  at $1. There can be no assurance,  however, that the
Fund will at all times be able to  maintain a constant  $1 NAV per share.  Such
procedures include review of the Fund's holdings at such intervals as is deemed
appropriate to determine  whether the Fund's NAV calculated by using  available
market quotations deviates from $1 per share and, if so, whether such deviation
may  result  in  material   dilution  or  is   otherwise   unfair  to  existing
shareholders.  In the event that it is determined that such a deviation exists,
the Board of Trustees will take such corrective  action as it regards necessary
and appropriate. Such action may include selling portfolio instruments prior to
maturity to realize  capital  gains or losses or to shorten  average  portfolio
maturity,  withholding  dividends,  or  establishing  a NAV per  share by using
available market quotations.

                     CONDITIONS OF PURCHASE AND REDEMPTION

NONPAYMENT

If any order to purchase  shares is canceled due to  nonpayment or if the Trust
does not receive good funds either by check or electronic funds transfer,  USAA
Shareholder  Account Services (Transfer Agent) will treat the cancellation as a
redemption of shares  purchased,  and you will be responsible for any resulting
loss  incurred  by the  Fund  or the  Manager.  If you are a  shareholder,  the
Transfer Agent can redeem shares from your account(s) as reimbursement  for all
losses.  In addition,  you may be prohibited  or restricted  from making future
purchases  in any of the USAA  Family of Funds.  A $15 fee is  charged  for all
returned items, including checks and electronic funds transfers.

                                       2
<PAGE>
TRANSFER OF SHARES

You may transfer Fund shares to another person by sending written  instructions
to the Transfer  Agent.  The account must be clearly  identified,  and you must
include  the  number  of  shares  to be  transferred,  the  signatures  of  all
registered owners, and all stock certificates, if any, which are the subject of
transfer.  You also need to send written  instructions signed by all registered
owners and supporting documents to change an account registration due to events
such as divorce,  marriage, or death. If a new account needs to be established,
you must complete and return an application to the Transfer Agent.

             ADDITIONAL INFORMATION REGARDING REDEMPTION OF SHARES

The value of your investment at the time of redemption may be more or less than
the cost at  purchase,  depending on the value of the  securities  held in each
Fund's  portfolio.  Requests  for  redemption  that are  subject to any special
conditions  or which  specify an effective  date other than as provided  herein
cannot be accepted. A gain or loss for tax purposes may be realized on the sale
of shares, depending upon the price when redeemed.

     The Board of Trustees may cause the  redemption of an account with a total
value of less than $500 provided (1) the value of the account has been reduced,
for reasons other than market action,  below the minimum initial  investment in
such Fund at the time of the establishment of the account,  (2) the account has
remained below the minimum level for six months, and (3) 60 days' prior written
notice of the proposed redemption has been sent to you. Shares will be redeemed
at the NAV on the date fixed for  redemption  by the Board of Trustees.  Prompt
payment will be made by mail to your last known address.

     The  Trust  reserves  the right to  suspend  the  right of  redemption  or
postpone  the date of  payment  (1) for any  periods  during  which the NYSE is
closed,  (2) when  trading  in the  markets  the  Trust  normally  utilizes  is
restricted, or an emergency exists as determined by the SEC so that disposal of
the  Trust's  investments  or  determination  of  its  NAV  is  not  reasonably
practicable,  or (3) for such other  periods as the SEC by order may permit for
protection of the Trust's shareholders.

     For the mutual  protection  of the investor  and the Funds,  the Trust may
require a signature  guarantee.  If  required,  each  signature  on the account
registration must be guaranteed.  Signature guarantees are acceptable from FDIC
member  banks,  brokers,  dealers,   municipal  securities  dealers,  municipal
securities  brokers,   government  securities  dealers,  government  securities
brokers,  credit unions,  national securities exchanges,  registered securities
associations,   clearing  agencies,  and  savings  associations.   A  signature
guarantee for active duty military  personnel  stationed abroad may be provided
by an officer of the United States Embassy or Consulate, a staff officer of the
Judge Advocate General, or an individual's commanding officer.

REDEMPTION BY CHECK

Shareholders in the Texas Tax-Free Money Market Fund may request that checks be
issued for their account. Checks must be written in amounts of at least $250.

     Checks issued to  shareholders of the Fund will be sent only to the person
in whose name the account is registered and only to the address of record.  The
checks  must be  manually  signed by the  registered  owner(s)  exactly  as the
account is registered. For joint accounts the signature of either or both joint
owners will be required on the check,  according  to the  election  made on the
signature  card.  You will  continue  to earn  dividends  until the  shares are
redeemed by the presentation of a check.

     When a check is presented to the Transfer Agent for payment,  a sufficient
number of full and  fractional  shares  from your  account  will be redeemed to
cover the amount of the check.  If the account balance is not adequate to cover
the amount of a check, the check will be returned unpaid.  Because the value of
each account changes as dividends are accrued on a daily basis,  checks may not
be used to close an account.

     The  checkwriting   privilege  is  subject  to  the  customary  rules  and
regulations  of State Street Bank and Trust  Company  (State Street Bank or the
Custodian)  governing checking accounts.  There is no charge to you for the use
of the checks or for subsequent reorders of checks.

     The Trust  reserves  the right to assess a  processing  fee  against  your
account for any  redemption  check not  honored by a clearing or paying  agent.
Currently,  this fee is $15 and is subject to change at any time. Some examples
of such dishonor are improper  endorsement,  checks  written for an amount less
than the minimum check amount,  and  insufficient or  uncollectible  funds.

     The Trust,  the  Transfer  Agent,  and State  Street Bank each reserve the
right to change or suspend the  checkwriting  privilege  upon 30 days'  written
notice to participating shareholders.

                                       3
<PAGE>
     You may  request  that the  Transfer  Agent stop  payment on a check.  The
Transfer Agent will use its best efforts to execute stop payment  instructions,
but does not guarantee that such efforts will be effective.  The Transfer Agent
will charge you $10 for each stop payment you request.

                                INVESTMENT PLANS

The Trust makes available the following investment plans to shareholders of the
Funds. At the time you sign up for any of the following  investment  plans that
utilize the electronic funds transfer  service,  you will choose the day of the
month  (the  effective  date) on which you  would  like to  regularly  purchase
shares.  When this day falls on a weekend or holiday,  the electronic  transfer
will take place on the last  business day before the  effective  date.  You may
terminate your participation in a plan at any time. Please call the Manager for
details and necessary forms or applications.

AUTOMATIC PURCHASE OF SHARES

INVESTRONIC(R) - The regular purchase of additional  shares through  electronic
funds transfer from a checking or savings account.  You may invest as little as
$50 per month.

DIRECT PURCHASE  SERVICE - The periodic  purchase of shares through  electronic
funds  transfer  from  a   non-governmental   employer,   an   income-producing
investment, or an account with a participating financial institution.

DIRECT DEPOSIT PROGRAM - The monthly  transfer of certain  federal  benefits to
directly  purchase  shares of a USAA mutual  fund.  Eligible  federal  benefits
include:  Social Security,  Supplemental Security Income, Veterans Compensation
and Pension,  Civil Service  Retirement  Annuity,  and Civil  Service  Survivor
Annuity.

GOVERNMENT  ALLOTMENT - The  transfer of  military  pay by the U.S.  Government
Finance Center for the purchase of USAA mutual fund shares.

AUTOMATIC  PURCHASE  PLAN - The  periodic  transfer  of funds from a USAA money
market fund to purchase  shares in another  non-money  market USAA mutual fund.
There is a minimum investment  required for this program of $5,000 in the money
market fund, with a monthly transaction minimum of $50.

BUY/SELL  SERVICE - The  intermittent  purchase or redemption of shares through
electronic  funds  transfer to or from a checking or savings  account.  You may
initiate a "buy" or "sell" whenever you choose.

DIRECTED  DIVIDENDS  - If you own  shares  in more than one of the Funds in the
USAA  Family of Funds,  you may  direct  that  dividends  and/or  capital  gain
distributions  earned in one fund be used to purchase shares  automatically  in
another fund.

     Participation in these  systematic  purchase plans allows you to engage in
dollar-cost  averaging.  For additional  information concerning the benefits of
dollar-cost averaging, see APPENDIX C.

SYSTEMATIC WITHDRAWAL PLAN

If you own shares having a NAV of $5,000 or more in a single investment account
(accounts in different  Funds cannot be aggregated for this  purpose),  you may
request  that enough  shares to produce a fixed  amount of money be  liquidated
from the account monthly or quarterly. The amount of each withdrawal must be at
least $50. Using the electronic funds transfer service,  you may choose to have
withdrawals   electronically   deposited  at  your  bank  or  other   financial
institution. You may also elect to have checks mailed to a designated address.

     This plan may be initiated by depositing shares worth at least $5,000 with
the  Transfer  Agent  and  by  completing  the   Systematic   Withdrawal   Plan
application,  which  may be  requested  from  the  Manager.  You may  terminate
participation  in the plan at any time.  You are not  charged  for  withdrawals
under the Systematic  Withdrawal  Plan. The Trust will not bear any expenses in
administering the plan beyond the regular transfer agent and custodian costs of
issuing and redeeming shares. The Manager will bear any additional  expenses of
administering the plan.

     Withdrawals  will be made by redeeming full and  fractional  shares on the
date you select at the time the plan is established.  Withdrawal  payments made
under this plan may exceed  dividends  and  distributions  and, to this extent,
will  involve the use of  principal  and could  reduce the dollar value of your
investment  and  eventually  exhaust the  account.  Reinvesting  dividends  and
distributions  helps  replenish  the  account.  Because  share  values  and net
investment income can fluctuate, you should not expect withdrawals to be offset
by rising income or share value gains.

     Each  redemption  of shares  may  result in a gain or loss,  which must be
reported  on your  income tax  return.  Therefore,  you should keep an accurate
record of any gain or loss on each withdrawal.

                              INVESTMENT POLICIES

The sections  captioned  WHAT ARE EACH FUND'S  INVESTMENT  OBJECTIVES  AND MAIN
STRATEGIES?  and FUND  INVESTMENTS in the Prospectus  describe the  fundamental
investment  objective(s) and the investment  policies  applicable to each Fund.
Each Fund's objective(s) cannot be changed without  shareholder  approval.  The
following is provided as additional information.

CALCULATION OF PORTFOLIO WEIGHTED AVERAGE MATURITIES

Weighted  average  maturity  is  derived  by  multiplying  the  value  of  each
investment by the number of days remaining to its maturity,  adding the results
of these  calculations,  and then dividing the total by the value of the Fund's
portfolio.  An obligation's  maturity is typically determined on a stated final
maturity basis, although there are some exceptions to this rule.

     With respect to obligations  held by the Texas Tax-Free Income Fund, if it
is  probable  that  the  issuer  of an  instrument  will  take  advantage  of a
maturity-shortening device, such as a call, refunding, or redemption provision,
the date on which the instrument will probably be called, refunded, or redeemed
may be considered to be its maturity  date.  Also, the maturities of securities
subject to sinking fund  arrangements are determined on a weighted average life
basis,  which is the average  time for  principal  to be repaid.  The  weighted
average life of these  securities  is likely to be  substantially  shorter than
their stated final maturity. In addition, for purposes of the Fund's investment
policies,  an instrument will be treated as having a maturity  earlier than its
stated  maturity date if the instrument has technical  features such as puts or
demand  features  that,  in the  judgment  of the  Manager,  will result in the
instrument being valued in the market as though it has the earlier maturity.

     The Texas  Tax-Free  Money Market Fund will  determine  the maturity of an
obligation in its portfolio in accordance  with Rule 2a-7 under the  Investment
Company Act of 1940, as amended (1940 Act).

REPURCHASE AGREEMENTS

Each Fund may invest up to 5% of its net  assets in  repurchase  agreements.  A
repurchase  agreement is a transaction  in which a security is purchased with a
simultaneous  commitment  to sell the security back to the seller (a commercial
bank or recognized securities dealer) at an agreed upon price on an agreed upon
date,  usually not more than seven days from the date of  purchase.  The resale
price  reflects the purchase  price plus an agreed upon market rate of interest
which is unrelated to the coupon rate or maturity of the purchased security.  A
repurchase  agreement  involves the  obligation of the seller to pay the agreed
upon  price,  which  obligation  is in  effect  secured  by  the  value  of the
underlying security. In these transactions,  the securities purchased by a Fund
will have a total value  equal to or in excess of the amount of the  repurchase
obligation and will be held by the Funds' custodian until  repurchased.  If the
seller defaults and the value of the underlying  security declines,  a Fund may
incur a loss and may incur  expenses in selling the  collateral.  If the seller
seeks relief under the bankruptcy  laws, the  disposition of the collateral may
be delayed or limited. Any investments in repurchase  agreements will give rise
to income which will not qualify as  tax-exempt  income when  distributed  by a
Fund.

WHEN-ISSUED SECURITIES

Each  Fund may  invest in new  issues of  tax-exempt  securities  offered  on a
when-issued  basis;  that is, delivery and payment take place after the date of
the commitment to purchase,  normally  within 45 days.  Both price and interest
rate are fixed at the time of commitment. The Funds do not earn interest on the
securities  until  settlement,  and the  market  value  of the  securities  may
fluctuate  between purchase and settlement.  Such securities can be sold before
settlement date.

     Cash or high  quality  liquid debt  securities  equal to the amount of the
when-issued  commitments  are  segregated  at the Fund's  custodian  bank.  The
segregated  securities are valued at market,  and daily adjustments are made to
keep the  value of the cash and  segregated  securities  at least  equal to the
amount of such  commitments by the Fund. On the settlement  date, the Fund will
meet its obligations  from then available cash, sale of segregated  securities,
sale of other securities, or sale of the when-issued securities themselves.

MUNICIPAL LEASE OBLIGATIONS

Each  Fund may  invest in  municipal  lease  obligations  and  certificates  of
participation in such obligations  (collectively,  lease obligations).  A lease
obligation  does not constitute a general  obligation of the  municipality  for
which the municipality's taxing power is pledged, although the lease obligation
is ordinarily backed by the municipality's  covenant to budget for the payments
due under the lease obligation.

     Certain  lease  obligations  contain   "non-appropriation"  clauses  which
provide  that the  municipality  has no  obligation  to make  lease  obligation
payments in future  years unless  money is  appropriated  for such

                                       5
<PAGE>
purpose on a yearly basis. Although  "non-appropriation"  lease obligations are
secured by the leased  property,  disposition  of the  property in the event of
foreclosure might prove difficult. In evaluating a potential investment in such
a lease  obligation,  the Manager will consider:  (1) the credit quality of the
obligor,  (2) whether the  underlying  property is essential to a  governmental
function,  and (3) whether the lease obligation contains covenants  prohibiting
the obligor from  substituting  similar  property if the obligor  fails to make
appropriations for the lease obligation.

TEMPORARY DEFENSIVE POLICY

Each Fund may on a temporary basis because of market,  economic,  political, or
other  conditions,  invest up to 100% of its  assets in  short-term  securities
whether  or not they  are  exempt  from  federal  income  taxes.  Such  taxable
securities may consist of obligations of the U.S.  Government,  its agencies or
instrumentalities,  and  repurchase  agreements  secured  by such  instruments;
certificates  of  deposit  of  domestic  banks  having  capital,  surplus,  and
undivided  profits in excess of $100 million;  banker's  acceptances of similar
banks; commercial paper; and other corporate debt obligations.

OTHER POLICIES

Each Fund may lend its  securities  and engage in short sells  against the box.
The Texas Tax-Free  Income Fund may also invest in options,  financial  futures
contracts,  and options on financial futures contracts.  However,  the Funds do
not intend to engage in any of these  practices  during the coming year without
first supplying further information in the Prospectus.

                            INVESTMENT RESTRICTIONS

The following  investment  restrictions have been adopted by the Trust for each
Fund. These restrictions may not be changed for any given Fund without approval
by the lesser of (1) 67% or more of the voting securities  present at a meeting
of the Fund if more than 50% of the outstanding  voting  securities of the Fund
are  present  or  represented  by  proxy or (2)  more  than  50% of the  Fund's
outstanding voting securities.  The investment  restrictions of one Fund may be
changed without affecting those of the other Fund.

Under the restrictions, neither Fund will:

(1)  with respect to 75% of its total  assets,  purchase the  securities of any
     issuer (except Government Securities,  as such term is defined in the 1940
     Act) if, as a result,  the Fund would own more than 10% of the outstanding
     voting  securities  of such  issuer or the Fund would have more than 5% of
     the value of its total assets  invested in the  securities of such issuer;
     for purposes of this  limitation,  identification  of the "issuer" will be
     based on a determination of the source of assets and revenues committed to
     meeting interest and principal payments of each security;  for purposes of
     this limitation the state of Texas or other  jurisdictions and each of its
     separate    political    subdivisions,     agencies,    authorities    and
     instrumentalities shall be treated as a separate issuer;

(2)  borrow  money,  except  that a Fund may  borrow  money  for  temporary  or
     emergency  purposes in an amount not exceeding 33 1/3% of its total assets
     (including the amount borrowed) less liabilities  (other than borrowings),
     nor will either Fund purchase  securities when its borrowings exceed 5% of
     its total assets;

(3)  purchase any securities which would cause 25% or more of the value of that
     Fund's  total  assets  at the  time of such  purchase  to be  invested  in
     securities  the interest  upon which is derived from  revenues or projects
     with similar  characteristics,  such as toll road revenue  bonds,  housing
     revenue  bonds,  electric power project  revenue  bonds,  or in industrial
     revenue bonds which are based,  directly or  indirectly,  on the credit of
     private  entities  of  any  one  industry;  provided  that  the  foregoing
     limitation  does not apply with respect to  investments  in U.S.  Treasury
     Bills, other obligations issued or guaranteed by the U.S. Government,  its
     agencies  and  instrumentalities,  and, in the case of the Texas  Tax-Free
     Money Market Fund,  certificates  of deposit and banker's  acceptances  of
     domestic banks;

(4)  issue senior securities, except as permitted under the 1940 Act;

(5)  underwrite  securities of other issuers,  except to the extent that it may
     be deemed to act as a statutory  underwriter  in the  distribution  of any
     restricted securities or not readily marketable securities;

(6)  purchase or sell real estate  unless  acquired as a result of ownership of
     securities or other instruments (but this shall not prevent investments in
     securities secured by real estate or interests therein);

(7)  lend any securities or make any loan if, as a result, more than 33 1/3% of
     its  total  assets  would  be lent to  other  parties,  except  that  this
     limitation does not apply to purchases of debt securities or to repurchase
     agreements; or

                                       6
<PAGE>
(8)  purchase or sell  commodities  or  commodities  contracts  except that the
     Texas  Tax-Free  Income Fund may invest in  financial  futures  contracts,
     options thereon, and similar instruments.

ADDITIONAL RESTRICTION

The following  restriction is not considered to be a fundamental  policy of the
Funds.  The Board of Trustees may change this  additional  restriction  without
notice to or approval by the shareholders.

     The Texas  Tax-Free  Income Fund may not invest more than 15% of the value
of its net assets and the Texas  Tax-Free Money Market Fund may not invest more
than 10% of the  value of its net  assets  in  illiquid  securities  (including
repurchase agreements maturing in more than seven days).

                          SPECIAL RISK CONSIDERATIONS

The following only highlights some of the more significant financial trends and
budget  information  affecting  the state of Texas,  and is based  solely  upon
information drawn from official statements and prospectuses relating to various
securities offerings by the state of Texas, its agencies and instrumentalities,
as  available on the date of this SAI. The Funds have made no attempt to verify
the accuracy or  completeness  of this  information  or the absence of material
adverse  changes  occurring  subsequent  to the date of such  information.  The
historical  data and trends  discussed  in this  section are not intended to be
exhaustive  or to predict  future  events or trends.  There can be no assurance
that past  trends  will  continue  or that there will be an absence of material
adverse changes subsequent to the date of this SAI.

     LACK  OF  DIVERSIFICATION.  Because  the  Texas  Funds  concentrate  their
investments in a specific state,  there are risks associated with investment in
the Funds  which  would not exist if the Funds'  investments  were more  widely
diversified.  These risks include the possible  enactment of new legislation in
the State which could  affect  state  and/or  municipal  obligations,  economic
factors which could affect these obligations,  and varying levels of supply and
demand for state and municipal obligations.

     STATE DEBT.  Except as  specifically  authorized,  the Texas  Constitution
generally prohibits the creation of debt by or on behalf of the State, with two
exceptions:  (i) debt created to supply  deficiencies  in revenues which do not
total more than $200,000 at any time, and (ii) debt to repel invasion, suppress
insurrection,  defend the State in war, or pay existing debt. In addition,  the
Texas  Constitution  prohibits the  Legislature  from lending the credit of the
State to any person,  including  municipalities,  or pledging the credit of the
State in any  manner  for the  payment of the  liabilities  of any  individual,
association of individuals, corporation or municipality. The limitations of the
Constitution  do not  prohibit the issuance of revenue  bonds,  however,  since
Texas  courts  (like  the  courts  of  most  states)  have  held  that  certain
obligations do not create a "debt" within the meaning of the Constitution.  The
state of Texas and various  state  agencies  have issued  revenue bonds payable
from the  revenues  produced  by  various  facilities  or from  lease  payments
appropriated by the  Legislature.  Furthermore,  obligations  which are payable
from funds  expected to be available  during the current  budget  period do not
constitute  "debt" within the meaning of the  Constitution.  Certain short term
obligations,  like the Tax and Revenue  Anticipation  Notes issued by the Texas
Comptroller of Public Accounts,  which mature within the biennial budget period
in which they are issued (discussed below in more detail), are not deemed to be
"debt" within the meaning of the state constitutional prohibition.

     Voters  in  Texas  have  from  time to time  by  constitutional  amendment
authorized the issuance of general  obligation  indebtedness for which the full
faith,  credit and taxing  power of the State are pledged.  In some cases,  the
authorized  indebtedness  may  not  be  issued  without  the  approval  of  the
Legislature,   but  in  other  cases,   the   constitutional   amendments   are
self-operating and the debt may be issued without specific legislative action.

     Various state  agencies  have the  authority to issue  general  obligation
bonds. The Veterans' Land Board is authorized to issue general obligation bonds
to finance  the  purchase  of land and  housing by  veterans.  The Texas  Water
Development Board (the "TWDB") is authorized to issue general  obligation bonds
to make funds available to municipalities  and certain other governmental units
for the conservation  and development of water  resources;  the acquisition and
development  of water  storage  facilities  for the  filtration,  treatment and
transportation  of water;  water quality  enhancement  purposes;  flood control
purposes;  and water-efficient  irrigation systems.  Additionally,  the TWDB is
authorized to incur unlimited contractual  obligations to the United States for
the  acquisition  and  development  of water  storage  facilities in reservoirs
constructed by the United States.  These  obligations are declared by the Texas
Constitution to be general obligations of the State. On November 4, 1997, Texas
voters decided to allow the TWDB to

                                       7
<PAGE>
consolidate  existing,  specific  general  obligation  authority  for  separate
purposes  in  order  to more  effectively  meet  demand  experienced  for  such
purposes.

     The Texas  Agricultural  Finance  Authority  (the "TAFA") is authorized to
issue  general  obligation  bonds  to  provide  financial  assistance  for  the
expansion,  development  and  diversification  of  production,  processing  and
marketing of Texas agricultural products.  Additionally, the TAFA is authorized
to issue  general  obligation  bonds  for a farm  and  ranch  land  acquisition
program.  The Texas Parks and Wildlife Department (the "TPWD") is authorized to
issue general  obligation  bonds to finance the  acquisition and development of
state parks.  The Texas Higher  Education  Coordinating  Board is authorized to
issue general  obligation  bonds to finance  student loans.  The Texas National
Research  Laboratory  Commission  (the "TNRLC") was authorized to issue general
obligation  bonds  to aid in the  construction  of the  "superconducting  super
collider" project. Given the decision by the U.S. Congress to terminate federal
funding for the super collider, the Legislature made provisions for the removal
of the remaining bond  authority.  Elimination of the remaining  super collider
general  obligation  authority  required voter approval,  which was received in
November 1995.  Additionally,  the General  Appropriations  Act for the 1998-99
biennium  includes  provisions  for the  defeasance  of all or a portion of the
outstanding  general  obligation  bonds  associated  with  the  super  collider
project.

     The Texas Public  Finance  Authority  (the "TPFA") is  authorized to issue
general obligation bonds to finance the acquisition, construction and equipping
of new  facilities,  and major repair or renovation of existing  facilities for
correction institutions and mental health and mental retardation  institutions.
Effective January 1, 1992, TPFA is authorized to issue general obligation bonds
on  behalf  of the  TNRLC  and the  TPWD.  The  Texas  Department  of  Economic
Development,  formerly the Texas Department of Commerce, is authorized to issue
general obligation bonds to provide loans to finance the  commercialization  of
new or improved  products or processes  developed in Texas and to stimulate the
development  of  small  businesses  in  Texas.   Certain  public  colleges  and
universities are authorized to issue bonds payable from certain  appropriations
required by the Constitution, without limitation as to principal amount, except
that the debt  service  on such  bonds may not  exceed 50 percent of the amount
appropriated each year.

     Credit  ratings on state debt are  dependent  upon  several  economic  and
political  factors,  including  the ability to  continue to fund a  substantial
portion of the debt  service  on  general  obligation  debt from  general  fund
revenue in the annual  state  budget and the ability to maintain  the amount of
authorized debt within the range of affordability.

     OUTSTANDING  DEBT  SUMMARY.  Texas  had a total  of  approximately  $11.79
billion in state bonds and notes  outstanding on August 31, 1998, down slightly
from $11.8 billion on August 31, 1997.  This figure includes  commercial  paper
and variable rate notes;  however,  it does not include  short-term debt issued
for cash management purposes (described below).  Approximately $5.19 billion of
Texas' total state debt  outstanding  on August 31,  1998,  carries the general
obligation  pledge of the State.  These bonds carry a constitutional  pledge of
the full faith and credit of the State to pay off the bonds if program revenues
are insufficient.  General  obligation debt is the only legally binding debt of
the State.  The  issuance of general  obligation  bonds  requires  passage of a
proposition  by  two-thirds  of both houses of the Texas  Legislature  and by a
majority of Texas voters. The remaining debt,  non-general  obligation debt, is
dependent  only  on  the  revenue   stream  of  a  particular   program  or  an
appropriation   from  the  Legislature.   General  obligation  and  non-general
obligation bonds that depend on general revenue for debt service are classified
as "not  self-supporting" for purposes of this disclosure.  Bonds which are not
self-supporting  depend  solely on the State's  general  revenue  fund for debt
service,  drawing funds from the same source used by the Legislature to finance
the operation of state  government.  "Not  self-supporting"  bonds  outstanding
totaled  approximately $3.24 billion of total state bonds outstanding as of the
end of August  1998.  Debt  service on  "self-supporting"  bonds (both  general
obligation and non-general  obligation  bonds) is paid from sources outside the
State's   general   revenue  fund  or  outside   state   government   entirely.
Self-supporting bonds, therefore, do not put direct pressure on state finances.

     During  fiscal year 1998,  Texas state  agencies and  universities  issued
approximately $2.43 billion in bonds, including $1.2 billion in new money bonds
(not  including  commercial  paper) and $1.22 billion in refunding  bonds.  New
money bond issues  raise  additional  funds and add to the State's  outstanding
debt,while refunding bonds, generally,  replace bonds issued previously.  Texas
State agencies and  universities  plan to issue  approximately  $2.8 billion in
bonds and commercial paper during fiscal year 1999.  Approximately $1.8 billion
will be issued to finance projects,  programs and facilities, and approximately
$961 million will be issued to refund existing debt.

                                       8

     As of August 31, 1998, Texas had approximately  $5.3 billion in authorized
but  unissued  bonds.  Authorized  bonds are those which may be issued  without
further action by the  Legislature.  Approximately  $3 billion of 57 percent of
these authorized but unissued bonds would be state general  obligation debt. At
the end of fiscal 1997,  $852.5  million or 16 percent of the total  authorized
but  unissued  bonds would  require the payment of debt  service  from  general
revenue.  The  remainder  are designed to be  self-supporting  through  program
revenues.

     GENERAL  OBLIGATION DEBT. Much of the outstanding  bonded  indebtedness of
the State is  designed  to be  self-supporting,  even though the full faith and
credit of the State is pledged for its payment.  Revenues from land and housing
programs are expected to be  sufficient  to pay  principal  and interest on all
outstanding Veterans Land Board bonds. Almost all of the bonded indebtedness of
the TWDB is self-supporting to the extent that all funds provided from payments
on obligations of political subdivisions for water projects are applied to such
bonded  indebtedness;  such revenues have been  sufficient to pay the principal
and  interest  on  such  bonds  since  fiscal  year  1980  without   resort  to
appropriated  funds.  The  remaining  portion  of the  TWDB's  debt  is for the
Economically Distressed Areas Program. These bonds do not depend totally on the
State's  general  revenue for debt service;  however,  up to  approximately  90
percent of the bonds issued may be used for grants. Revenues from student loans
are pledged to pay the principal and interest on the  outstanding  bonds of the
Texas Higher Education Coordinating Board.

     The  general  obligation  bonds that have been  issued by the TPFA are not
self-supporting.  All debt  service  on these  bonds is paid  from the  State's
general  revenue  fund.  The  higher  education  constitutional  bonds  are not
explicitly a general  obligation or full faith and credit bond, but the revenue
pledge has the same effect. Debt service is paid from an annual  constitutional
appropriation  to qualified  institutions  of higher  education  from the first
monies coming into the State  Treasury that are not otherwise  dedicated by the
Constitution.

     STATE REVENUE BONDS. The TPFA and the Military Facilities  Commission (the
"MFC"),  formerly known as the National  Guard Armory Board,  have authority to
issue  state-backed  lease revenue  bonds.  Such  obligations do not constitute
"debt"  within the  meaning of the Texas  Constitution,  even  though  they are
payable from rental  payments  appropriated  and made by the State under leases
covering the facilities financed with the proceeds of the obligations.  The MFC
is authorized to issue bonds,  payable  solely from rents received with respect
to  buildings  constructed  by it and  leased  to the  National  Guard  without
limitation as to amount.  Effective  January 1, 1992,  the TPFA issues bonds on
behalf of the MFC.

     The TNRLC had the authority to issue  state-backed  lease  revenue  bonds,
however,  on June 1, 1995,  all of these  outstanding  bonds  issued to provide
funding  for the super  collider  project  were  defeased  or  redeemed.  As of
September  1, 1995,  the Texas  Legislature  rescinded  the  TNRLC's  remaining
revenue bond authority.

     The TPFA is  authorized to issue both  lease-revenue  bonds to finance the
construction, acquisition or renovation of state office buildings and equipment
revenue bonds to finance the  acquisition of equipment.  For the  lease-revenue
bonds,  the authorized  amount of debt is equal to 1.5 times the estimated cost
of projects that have been approved by the Legislature.  Effective September 1,
1997, the TPFA is also  authorized to issue park  improvement  revenue bonds on
behalf of the TPWD. These bonds are payable from general revenue appropriations
to TPWD.

     In addition to the foregoing revenue obligations issued by state agencies,
additional  state  programs  may be  financed  with  revenue  bonds or  similar
obligations   payable  from  revenues  generated  by  the  specific  authorized
programs,  and not from the general  revenues of the State or its taxing power.
Among the State  entities  authorized to issue such revenue bonds are the Texas
Water Development Board, the Texas Water Resources Finance Authority, the Texas
Agricultural  Finance  Authority,  the State Comptroller on behalf of the Texas
School  Facilities  Finance  Program,  the  Texas  Department  of  Housing  and
Community  Affairs,  the Texas  Department of Economic  Development,  the Texas
Public  Finance  Authority,  the Texas  Low-Level  Radioactive  Waste  Disposal
Authority,  the Texas Veterans' Land Board and Texas colleges and universities.
Effective  September 1, 1997, the Texas Department of  Transportation  received
authority to issue revenue bonds, and the TPFA was authorized to issue bonds on
behalf  of  the  Texas   Low-Level   Radioactive   Waste  Disposal   Authority.
Additionally,  as of September  1, 1997,  the name of the Texas  Department  of
Commerce was changed to the Texas Department of Economic  Development,  and the
outstanding debt and assets of the Texas Turnpike Authority were transferred to
a newly created regional tollway authority, the North Texas Tollway Authority.

     RECENT  DEVELOPMENTS  AFFECTING  STATE DEBT.  Texas Revised Civil Statutes
Article 717k-7(8)  prohibits the Legislature from authorizing  additional state
debt payable from general revenues, including authorized but unissued bonds and
lease  purchase  contracts  in excess of $250,000 or for a term of greater than
five years,  if the  resulting  annual debt service  exceeds five percent of an
amount equal to the average amount of general revenue for the three immediately
preceding years,  excluding  revenues  constitutionally  dedicated for purposes
other than payment of debt service.  Self-supporting  general obligation bonds,
although  backed by the full  faith and  credit of the  State,  are  reasonably
expected to be paid from other revenue sources and are not expected to create a
general  revenue  draw.  Pursuant  to HJR 59,  passed by the 75th  Legislature,
Proposition  11 proposed a  constitutional  amendment to add the  provisions of
Article 717k-7(8) to the  Constitution.  On November 4, 1997 Proposition 11 was
passed.   The  provision  is  now  Article  III,  Section  49-j  of  the  Texas
Constitution.

     Although not  specifically a debt issue,  pursuant to HJR 8, passed by the
75th  Legislature,  Proposition  13 was submitted to Texas voters and passed on
November 4, 1997. Proposition 13 proposed a constitutional  amendment to extend
the State's full faith and credit to the Texas  Tomorrow  Fund and  established
the Fund as a  constitutionally  protected  fund.  The Texas  Tomorrow  Fund is
dedicated to the prepayment of higher education tuition and fees.

     SHORT TERM BORROWING. By statute, the Texas Comptroller of Public Accounts
is  authorized  to  make  interfund   transfers  of  surplus  cash,   excluding
constitutionally  dedicated revenues, between funds in the Treasury in order to
avoid  temporary cash  deficiencies in the General Revenue Fund. This procedure
effectively  allows the  Comptroller of Public  Accounts to borrow against cash
balances held in special funds to finance  deficiencies  in the General Revenue
Fund caused by timing differences  between cash receipts and cash expenditures.
Any surplus cash  transferred  to the General  Revenue fund must be returned to
the fund from which it was taken as soon as practicable. Depository interest on
funds so  transferred  is allocated  as if the funds had not been  transferred.
During fiscal 1998 approximately  $2.9 billion in Tax and Revenue  Anticipation
Notes were issued by the  Comptroller.  The  Comptroller is authorized to issue
Tax and  Revenue  Anticipation  Notes  ("Notes")  on behalf of the State  under
legislation  which  became  effective in October  1986.  Under the terms of the
legislation,  Notes may be issued  solely to  coordinate  the State's cash flow
within a fiscal year and must mature and be paid in full during the biennium in
which the Notes are  issued.  Interfund  borrowing  was not used in fiscal year
1998 due to the  consolidation  of numerous funds into the General Revenue Fund
on August 31, 1993.  The total amount of Notes issued and  interfund  borrowing
may not exceed 25  percent  of the taxes and  revenues  to be  credited  to the
State's  General  Revenue  Fund  for  the  fiscal  year  as  forecasted  by the
Comptroller.

     Several state agencies and  universities use commercial paper and variable
rate notes to provide financing for equipment, interim construction, and loans.
As of  August  31,  1998,  a total of $1.7  billion  was  authorized  for state
commercial paper or variable-rate note programs.  Of this amount $593.4 million
was outstanding as of the end of fiscal 1998.

     SOURCES OF  REVENUE.  As a result of the  State's  expansion  in  Medicaid
spending  and  other  Health  and Human  Services  programs  requiring  federal
matching  revenues,  federal receipts were the State's leading source of income
in fiscal  1998.  Sales tax,  which had been the main source of revenue for the
previous twelve years prior to fiscal 1993, was second.  Licenses,  fees, fines
and  penalties  were the third  largest  revenue  source to the State in fiscal
1998. Motor fuels taxes and motor vehicle  sales/rental  taxes were the State's
fourth and fifth largest revenue sources. The remainder of the State's revenues
are derived  primarily from interest and investment  income,  lottery proceeds,
cigarette and tobacco,  franchise,  oil and gas severance and other taxes.  The
State has no personal or corporate income tax, although the State does impose a
corporate  franchise  tax based on the amount of a  corporation's  capital  and
"earned  surplus,"  which  includes  corporate  net  income and  officers'  and
directors' compensation.

     POTENTIAL FOR REDUCTION OF STATE  REVENUES AND DEBT SERVICE.  There can be
no assurance that the State will not face budget gaps, decreases in revenues or
deficits  in future  years  resulting  from a  disparity  between  tax or other
revenues  projected and the spending  required to maintain  state  programs and
debt service at current levels.  Furthermore,  the State is a party to numerous
lawsuits  in  which  an  adverse  decision  could  require   extraordinary  and
unbudgeted  expenditures.  These or other  events  could  result in the State's
inability to pay debt as it becomes due which could also affect  negatively the
value of your investment in the Texas Funds. Notwithstanding the foregoing, the
state of Texas finished  fiscal 1998 with a $3.3 billion  positive cash balance
in the General Revenue Fund. This was the eleventh  consecutive year that Texas
has ended a fiscal year with a positive balance in the General Revenue Fund.

                                      10

     LIMITATIONS ON TAXING POWER. The Constitution prohibits the state of Texas
from levying ad valorem  taxes on property for general  revenue  purposes.  The
Constitution also limits the rate of growth of appropriations from tax revenues
not dedicated by the Constitution  during any biennium to the estimated rate of
growth for the State's  economy.  The Legislature may avoid the  constitutional
limitations if it finds,  by a majority vote of both houses,  that an emergency
exists.  The Constitution  authorizes the Legislature to provide by law for the
implementation  of this  restriction,  and the  Legislature,  pursuant  to such
authorization,  has defined the estimated rate of growth in the State's economy
to mean the estimated increase in state personal income.

     APPROPRIATIONS  AND  BUDGETING.   The  Texas   Constitution   requires  an
appropriation  for  any  funds  to  be  drawn  out  of  the  Treasury.  Certain
appropriations  are  made  by  the  Constitution  and do  not  require  further
legislative  action,  although  the  Legislature  frequently  makes a  parallel
appropriation.  All other  appropriations must be made through a bill passed by
the Legislature and approved by the Governor or passed by the Legislature  over
the Governor's veto. Legislative appropriations are limited by the Constitution
to a period of two years. Claims must be filed against an appropriation  within
two years after the end of the fiscal year for which the appropriation is made,
except for construction appropriations, against which claims may be made for up
to  four  years.  Article  III,  Section  49a of the  Texas  Constitution,  the
so-called  "pay-as-you-go"  provision,  provides that an appropriation from any
fund other than the General  Revenue Fund is not valid if it exceeds the amount
of cash and estimated  revenues of the fund from which such appropriation is to
be paid. No  appropriations  bill passed by the  Legislature may be sent to the
Governor  for  consideration  until  the  Comptroller  of Public  Accounts  has
certified that the amounts  appropriated are within the amounts estimated to be
available in the affected funds.

     Budgeting for the State is handled  through the  Governor's  Budget Office
and the Legislative  Budget Board.  By statute,  the Governor has been made the
chief  budget  officer of the State,  which is a function  carried out by staff
members who constitute the Governor's  Budget Office.  The  Legislature has its
own budget agency in the Legislative Budget Board. The Governor's Budget Office
and the Legislative  Budget Board  generally  cooperate with respect to matters
pertaining to the preparation of budgets and prepare uniform  instructions  and
forms for budget requests.  The Governor and the Legislative  Budget Board each
make separate  submissions to the  Legislature.  The  Governor's  submission is
usually in the form of a budget proposal and the Legislative  Budget Board's is
in the form of a draft appropriations bill to be submitted for consideration by
the  Legislature.  The  Governor  is  authorized  by  statute to submit a draft
appropriations  bill, or the bill may be introduced  in the  Legislature  along
with the bill prepared by the Legislative Budget Board.

     NON-LEGISLATIVE   POWERS   AFFECTING   APPROPRIATIONS.   The  Governor  is
authorized by statute to make findings of any fact specified by the Legislature
in any  appropriations  bill as a  contingency  to the  expenditure  of  funds.
Accordingly,   the  Governor  has  some  minimal   discretion  to  prevent  the
expenditure of funds,  exercisable in situations in which an appropriation made
by the  Legislature is conditioned  upon the occurrence of a given event or the
existence of a given fact.

     The  Legislature  has provided a means of dealing with fiscal  emergencies
under which the Governor is empowered to authorize  expenditures from a general
appropriation  made  by  the  Legislature  specifically  for  emergencies.  The
Legislature  is not obligated to appropriate  any amount for such purpose,  but
customarily  does so. The Governor may not  authorize  the  expenditure  of the
emergency  funds unless a  certification  is made to the  Comptroller of Public
Accounts that an emergency and imperative public necessity requiring the use of
such funds exists and the  Comptroller of Public  Accounts  determines  that no
other funds are available for such purpose.  Any  expenditure  so authorized by
the  Governor  may only be used in those  instances in which no other funds are
available for purposes  specifically  appropriated  by the  Legislature  due to
exhaustion of appropriations.

     The  Legislature,  in the second called  session held during the Summer of
1987,  enacted a budget  execution law which gave the Governor,  subject to the
review  of the  Legislative  Budget  Board,  the  ability  to make  changes  in
legislative  appropriations  during  periods  when  the  Legislature  is not in
session.  The  statute was amended in 1991,  giving both the  Governor  and the
Legislative  Budget Board the authority to make proposals  which require that a
state agency be prohibited from spending an  appropriation,  which require that
an agency be obligated to expend an  appropriation,  or which affect the manner
in which part or all of an  appropriation  made by the Legislature to an agency
may  be  distributed  or  redistributed.  In  addition,  the  Governor  or  the
Legislative Budget Board, upon making a determination that an emergency exists,
may propose  that an  appropriation  made to a state agency be  transferred  to
another agency,  that an appropriation be retained by the agency but used for a
different purpose or that the time when an

                                      11
<PAGE>
appropriation  is made available to a state agency be changed.  Funds which are
dedicated  by the  Constitution  may be  withheld  upon the  Governor's  or the
Legislative Budget Board's proposal,  but may not be transferred to other state
agencies,  except to an agency which is entitled to receive appropriations from
those funds under the terms of the Constitution.  Federal funds appropriated by
the Texas  Legislature may be transferred only as permitted by federal law. The
Governor's  or the  Legislative  Budget  Board's  use of the  budget  execution
provision is subject to publication and, in certain  instances,  public hearing
requirements.  In addition,  before the Governor's proposal may be executed, it
must be ratified by action of the  Legislative  Budget Board, or if proposed by
the Board, the proposal must be ratified by the Governor.  The affirmative vote
of a majority of the members of the Legislative Budget Board from each house of
the Legislature is necessary for the adoption of any budget execution order.

     Except  under  the  circumstances  set  forth  above,   appropriations  or
adjustments  of  appropriations   may  currently  be  authorized  only  by  the
Legislature.

     PUBLIC SCHOOL FINANCE. In 1984, a group of property-poor  school districts
and the  Mexican-American  Legal Defense and Education  Fund filed  EDGEWOOD V.
BYNUM (later Kirby) against the school finance system,  challenging the state's
school finance system as  unconstitutional.  In April 1987 State District Judge
Harley  Clark  ruled in favor of the 67  property-poor  districts  finding  the
State's public school funding system  unconstitutional.  Two subsequent  school
finance  plans  were  drafted by the Texas  Legislature  in June 1990 and April
1991,  but  each  was  declared  unconstitutional.  In  late  May  1993,  Texas
legislators  passed  Senate Bill 7, which  directed  the State's 98  wealthiest
school  districts  to choose from among five  alternatives  for  sharing  their
overall property wealth with other, poorer districts. Judge McCown ordered that
the plan be  implemented  during the 1993-94  school year and, on December  10,
1993, upheld the  constitutionality  of SB 7. On May 25, 1994,  representatives
from  property-rich and property-poor  districts appealed the case to the Texas
Supreme Court.

     The Texas Supreme Court issued its opinion on January 30, 1995.  The court
upheld all  provisions  of SB 7 and  overturned  the lower  court's  mandate to
provide  additional  funding for school facilities in property-poor  districts.
The court ruled that convincing  evidence of an inability to provide facilities
had not been presented,  but that the absence of a separate  funding source for
facilities  could  cause  the  court  to  declare  the  entire  finance  system
unconstitutional.   The  court  also   cautioned   of  the   appearance   of  a
constitutionally-prohibited  state ad valorem tax if all districts  were forced
to tax at the capped value to maintain standards.

     RETIREMENT  SYSTEMS.  The state of Texas  operates  three  defined-benefit
retirement  systems:  the  Teacher  Retirement  System of Texas  ("TRST"),  the
Employee's  Retirement  System of Texas  ("ERST") and the  Judicial  Retirement
System  of  Texas  ("JRST").  In  addition,   state  employees,   except  those
compensated  on a fee basis,  are  covered  under the federal  Social  Security
System.  Political  subdivisions  of the  State  may  voluntarily  provide  for
coverage of their employees under the State's agreement with the federal Social
Security Administration.

     TRST and ERST are maintained on an actuarial basis. As of August 31, 1998,
the overfunded  actuarial  liability of TRST was approximately $2.4 billion and
the overfunded actuarial liability of ERST was approximately  $1,013.9 million.
The TRST fair value of  investments,  as of August 31, 1998, was $65.7 billion.
The ERST fair  value of pooled  investments  as of August 31,  1998,  was $18.8
billion.  Prior to 1985, JRST was maintained on a pay-as-you-go basis. However,
legislation enacted in 1985 divided JRST into two plans by changing the name of
the existing plan and establishing a second, separate plan. The new plan, known
as  Judicial  Retirement  System  of  Texas  Plan  Two,  is  maintained  on  an
actuarially  sound basis and covers  individuals who became  judicial  officers
after August 31, 1985. The unfunded actuarial  liability of JRST Plan Two as of
August 31, 1998, the most recent valuation date, was $3.16 million.  The period
required to amortize the unfunded  actuarial  liability of JRST Plan Two, given
the current rates, benefits, and actuarial assumptions, was estimated to be 6.7
years. The old plan, known as the Judicial Retirement System of Texas Plan One,
is maintained on a  pay-as-you-go  basis and covers  judicial  officers who are
active on August 31, 1985, or had retired on or before that date.

     Contributions  to the  retirement  systems  are made by both the State and
covered employees. The Texas Constitution mandates a state contribution rate of
not less than 6 percent or more than 10  percent  of  payroll  for the ERST and
TRST;  member  contributions  may not be less than 6 percent  of  payroll.  The
Legislature,  however,  may  appropriate  additional  funds as are  actuarially
determined to be needed to fund benefits authorized by law.

     For  the  1998-99   biennium,   the  Texas  Legislature  set  the  State's
contribution  rates to the retirement  systems at the following rates: ERST and
TRST at 6 percent of  payroll,  and JRST Plan Two at 16.83  percent of payroll.
Member  contribution  rates  are 6  percent  for ERST and JRST Plan Two and 6.4
percent for TRST.

                                      12

     The Legislature is prohibited by statute from implementing  changes in the
ERST,  JRST, and TRST systems that would cause the period  required to amortize
the unfunded actuarial liability of the plans to exceed thirty-one years. Prior
to the  adoption  of these  measures,  the State had no  official  limit on the
amortization period for unfunded actuarial  liability,  although the management
of both ERST and TRST had adopted an informal  policy of limiting the period to
thirty years.

     The State's  retirement  systems were created and are operated pursuant to
statutes  enacted by the  Legislature.  The  Legislature  has the  authority to
modify these statutes and, accordingly,  contribution rates, benefits,  benefit
levels and such other aspects of each system as it deems appropriate, including
the  provisions  limiting  changes that  increase the  amortization  period for
unfunded  actuarial  liability of any plan. The State's  retirement systems are
not subject to the funding and vesting  requirements of the Employee Retirement
Income  Security Act of 1974,  as amended,  although  Congress has from time to
time considered legislation that would regulate pension funds of public bodies.

     YEAR 2000 ISSUES.  The Year 2000 issue is the result of computer  programs
being written using two digits rather than four to define the applicable  year.
Any of the State's  computers,  computer programs or embedded systems that have
time-sensitive  hardware or software may  recognize a date using 00 as the year
1900 rather than the year 2000.  The issue is  compounded  by the fact that the
year  2000  (unlike  the year  1900) is a leap  year,  which  may also  lead to
incorrect  calculations.  All of  this  could  result  in  system  failures  or
miscalculations  causing  disruptions  of  operations,  including,  among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities.

     Most state agencies and  universities in Texas have been aware of the Year
2000 Issue for several  years.  In  September  1996,  the Texas  Department  of
Information  Resources  ("TDIR")  adopted a rule that all hardware and software
procurements by state agencies and universities  had to be Year-2000  compliant
as of January 1, 1997.  Through  the Texas  Association  of State  Systems  for
Computing and  Communications,  a Year 2000 Working Group was established  that
has been meeting on a monthly basis since  September 1996. The TDIR is focusing
on mission-critical  systems being operable in the Year 2000. These are systems
that impact public health, public safety and revenue  collections/distribution.
Based upon  reporting  received from state  agencies and  universities  through
February  1999,  the  Project  Office  of TDIR  currently  believes  that  most
mission-critical   systems  will  be  ready  for  the  Year  2000.   Additional
information  concerning  the State's Year 2000 efforts can be found on the TDIR
web-site at www.dir.state.tx.us/y2k.

                             PORTFOLIO TRANSACTIONS

     The Manager,  pursuant to the Advisory  Agreement dated June 25, 1993, and
subject to the general  control of the Trust's  Board of  Trustees,  places all
orders  for  the  purchase  and  sale  of Fund  securities.  Purchases  of Fund
securities are made either directly from the issuer or from dealers who deal in
tax-exempt  securities.  The Manager may sell Fund securities prior to maturity
if circumstances  warrant and if it believes such disposition is advisable.  In
connection  with  portfolio  transactions  for the Trust,  the Manager seeks to
obtain  the best  available  net price  and most  favorable  execution  for its
orders.  The Manager has no agreement or commitment to place  transactions with
any  broker-dealer  and no regular  formula is used to  allocate  orders to any
broker-dealer.  However,  the Manager may place security orders with brokers or
dealers who furnish  research or other services to the Manager as long as there
is no sacrifice in obtaining the best overall terms available. Payment for such
services  would be generated  only  through  purchase of new issue fixed income
securities.

     Such  research  and  other  services  may  include,  for  example:  advice
concerning  the  value  of  securities,   the  advisability  of  investing  in,
purchasing,  or selling  securities,  and the availability of securities or the
purchasers or sellers of securities;  analyses and reports concerning  issuers,
industries,  securities,  economic factors and trends,  portfolio strategy, and
performance  of  accounts;   and  various  functions  incidental  to  effecting
securities  transactions,  such as clearance  and  settlement.  These  research
services may also include access to research on third party data bases, such as
historical  data on  companies,  financial  statements,  earnings  history  and
estimates and corporate releases; real-time quotes and financial news; research
on specific fixed income securities;  research on international market news and
securities;  and rating  services  on  companies  and  industries.  The Manager
continuously  reviews the performance of the broker-dealers with whom it places
orders for  transactions.  The receipt of  research  from  broker-dealers  that
execute  transactions  on behalf of the Trust may be useful to the  Manager  in
rendering investment management services to other clients (including affiliates
of the Manager),  and conversely,  such research provided by broker-dealers who
have  executed  transaction  orders on behalf of other clients may be useful to
the Manager in carrying out its  obligations to the Trust.  While such research
is available to and may be

                                      13
<PAGE>
used  by  the  Manager  in  providing  investment  advice  to all  its  clients
(including affiliates of the Manager),  not all of such research may be used by
the Manager for the benefit of the Trust. Such research and services will be in
addition to and not in lieu of research and  services  provided by the Manager,
and the expenses of the Manager will not  necessarily be reduced by the receipt
of such supplemental research. See THE TRUST'S MANAGER.

     On occasions  when the Manager deems the purchase or sale of a security to
be in the best interest of the Trust,  as well as the Manager's  other clients,
the Manager,  to the extent permitted by applicable laws and  regulations,  may
aggregate  such  securities to be sold or purchased for the Trust with those to
be sold or purchased for other  customers in order to obtain best execution and
lower  brokerage  commissions,  if  any.  In  such  event,  allocation  of  the
securities  so  purchased  or sold,  as well as the  expenses  incurred  in the
transaction,  will be made by the Manager in the manner it considers to be most
equitable and consistent with its fiduciary  obligations to all such customers,
including the Trust. In some instances, this procedure may impact the price and
size of the position obtainable for the Trust.

     The  tax-exempt  security  market is typically a "dealer"  market in which
investment  dealers buy and sell bonds for their own accounts,  rather than for
customers,  and although the price may reflect a dealer's mark-up or mark-down,
the Trust pays no brokerage  commissions as such. In addition,  some securities
may be purchased directly from issuers.

PORTFOLIO TURNOVER RATE

The  portfolio  turnover  rate is  computed by  dividing  the dollar  amount of
securities  purchased or sold  (whichever  is smaller) by the average  value of
securities owned during the year.

     The rate of  portfolio  turnover  will not be a limiting  factor  when the
Manager deems changes in the Texas Tax-Free Income Fund's portfolio appropriate
in view of its  investment  objective.  For example,  securities may be sold in
anticipation  of a rise in interest  rates  (market  decline) or  purchased  in
anticipation  of a decline in interest  rates  (market rise) and later sold. In
addition, a security may be sold and another security of comparable quality may
be purchased at approximately  the same time in order to take advantage of what
the Fund believes to be a temporary  disparity in the normal yield relationship
between the two securities.  These yield  disparities may occur for reasons not
directly related to the investment  quality of particular issues or the general
movement of interest rates, such as changes in the overall demand for or supply
of various types of tax-exempt securities.

     For the last two fiscal years the Texas Tax-Free  Income Fund's  portfolio
turnover rates were as follows:

           1998 . . . . .  56.29%        1999 . . . . .  55.83%

     Portfolio  turnover  rates  have  been  calculated   excluding  short-term
variable rate securities,  which are those with put date intervals of less than
one year.

                             DESCRIPTION OF SHARES

The Funds are series of the Trust and are diversified. The Trust is an open-end
management investment company established as a business trust under the laws of
the state of Delaware pursuant to a Master Trust Agreement dated June 21, 1993.
The Trust is  authorized  to issue  shares of  beneficial  interest in separate
portfolios.  Four  such  portfolios  have  been  established,  two of which are
described in this SAI. Under the Master Trust Agreement,  the Board of Trustees
is  authorized to create new  portfolios in addition to those already  existing
without shareholder approval.

     Each  Fund's  assets  and all  income,  earnings,  profits,  and  proceeds
thereof, subject only to the rights of creditors, are specifically allocated to
such Fund. They constitute the underlying  assets of each Fund, are required to
be segregated on the books of account,  and are to be charged with the expenses
of such Fund.  Any general  expenses of the Trust not readily  identifiable  as
belonging  to a  particular  Fund are  allocated  on the  basis  of the  Funds'
relative net assets during the fiscal year or in such other manner as the Board
determines  to be fair and  equitable.  Each share of each Fund  represents  an
equal  proportionate  interest  in that  Fund  with  every  other  share and is
entitled to dividends and distributions out of the net income and capital gains
belonging to that Fund when declared by the Board.

     Under the Trust's Master Trust Agreement,  no annual or regular meeting of
shareholders is required. Thus, there will ordinarily be no shareholder meeting
unless  otherwise  required  by the  1940  Act.  Under  certain  circumstances,
however,  shareholders may apply to the Trustees for shareholder information in
order to obtain signatures to request a shareholder meeting. The Trust may fill
vacancies  on the Board or appoint new  Trustees if the result is that at least
two-thirds of the Trustees have still been elected by

                                      14
<PAGE>
shareholders. Moreover, pursuant to the Master Trust Agreement, any Trustee may
be  removed  by the vote of  two-thirds  of the  outstanding  Trust  shares and
holders  of 10% or more of the  outstanding  shares of the  Trust  can  require
Trustees  to call a meeting of  shareholders  for the  purpose of voting on the
removal of one or more  Trustees.  The Trust will  assist in  communicating  to
other  shareholders  about  the  meeting.   On  any  matter  submitted  to  the
shareholders,  the holder of each Fund share is  entitled to one vote per share
(with  proportionate  voting for fractional  shares) regardless of the relative
net asset  values of the  Funds'  shares.  However,  on  matters  affecting  an
individual  Fund, a separate vote of the shareholders of that Fund is required.
Shareholders  of a Fund are not  entitled  to vote on any matter  that does not
affect that Fund but which requires a separate vote of another Fund.  Shares do
not have cumulative voting rights, which means that holders of more than 50% of
the shares  voting for the  election of Trustees  can elect 100% of the Trust's
Board of  Trustees,  and the holders of less than 50% of the shares  voting for
the election of Trustees will not be able to elect any person as a Trustee.

     Shareholders of a particular Fund might have the power to elect all of the
Trustees of the Trust because that Fund has a majority of the total outstanding
shares of the  Trust.  When  issued,  each  Fund's  shares  are fully  paid and
nonassessable,  have no  pre-emptive  or  subscription  rights,  and are  fully
transferable. There are no conversion rights.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

TAXATION OF THE FUNDS

Each Fund intends to qualify as a regulated investment company under Subchapter
M of the  Internal  Revenue Code of 1986,  as amended (the Code).  Accordingly,
each  Fund will not be liable  for  federal  income  taxes on its  taxable  net
investment  income and net capital  gains  (capital  gains in excess of capital
losses)  that  are  distributed  to  shareholders,   provided  that  each  Fund
distributes  at  least  90% of its net  investment  income  and net  short-term
capital gain for the taxable year.

     To qualify as a regulated  investment  company,  a Fund must,  among other
things,  (1) derive in each  taxable year at least 90% of its gross income from
dividends,  interest, payments with respect to securities loans, gains from the
sale or other disposition of stock, securities or foreign currencies,  or other
income  derived  with  respect to its  business  of  investing  in such  stock,
securities or currencies (the 90% test) and (2) satisfy certain diversification
requirements  at the  close  of  each  quarter  of  the  Fund's  taxable  year.
Furthermore,  to pay tax-exempt interest income dividends,  at least 50% of the
value of each Fund's  total  assets at the close of each quarter of its taxable
year must consist of  obligations  the interest of which is exempt from federal
income tax. Each Fund intends to satisfy this requirement.

     The Code imposes a nondeductible  4% excise tax on a regulated  investment
company that fails to  distribute  during each calendar year an amount at least
equal  to the sum of (1)  98% of its  taxable  net  investment  income  for the
calendar  year,  (2) 98% of its  capital  gain net income for the  twelve-month
period  ending on October 31, and (3) any prior amounts not  distributed.  Each
Fund intends to make such distributions as are necessary to avoid imposition of
this excise tax.

     For federal income tax purposes,  debt  securities  purchased by the Funds
may be treated as having  original  issue  discount.  Original  issue  discount
represents interest income for federal income tax purposes and can generally be
defined as the  excess of the stated  redemption  price at  maturity  of a debt
obligation over the issue price. Original issue discount is treated for federal
income  tax  purposes  as earned by the  Funds,  whether  or not any  income is
actually received, and therefore is subject to the distribution requirements of
the  Code.  However,   original  issue  discount  with  respect  to  tax-exempt
obligations generally will be excluded from the Funds' taxable income, although
such  discount  will be included in gross  income for  purposes of the 90% test
described  previously.  Original  issue  discount  with  respect to  tax-exempt
securities  is accrued and added to the adjusted  tax basis of such  securities
for purposes of determining  gain or loss upon sale or at maturity.  Generally,
the amount of original  issue discount is determined on the basis of a constant
yield to maturity which takes into account the compounding of accrued interest.
An  investment  in a stripped  bond or stripped  coupon will result in original
issue discount.

     Debt securities may be purchased by the Funds at a market discount. Market
discount  occurs when a security is purchased at a price less than the original
issue price  adjusted for accrued  original issue  discount,  if any. The Funds
intend to defer  recognition of accrued market discount until maturity or other
disposition  of the bond. For securities  purchased at a market  discount,  the
gain realized on disposition  will be treated as taxable ordinary income to the
extent it does not exceed accrued market discount on the bond.

                                      15
<PAGE>
     The Funds may also  purchase  debt  securities  at a premium,  i.e.,  at a
purchase price in excess of face amount. With respect to tax-exempt securities,
the premium must be amortized to the maturity  date but no deduction is allowed
for the premium amortization. The amortized bond premium will reduce the Funds'
adjusted tax basis in the securities.  For taxable securities,  the premium may
be amortized if the Funds so elect. The amortized premium on taxable securities
is first offset against interest received on the securities and then allowed as
a deduction,  and, for  securities  issued after  September  27, 1985,  must be
amortized under an economic accrual method.

TAXATION OF THE SHAREHOLDERS

Taxable  distributions are generally  included in a shareholder's  gross income
for the taxable year in which they are received. Dividends declared in October,
November,  or December  and made  payable to  shareholders  of record in such a
month will be deemed to have been  received on December  31, if a Fund pays the
dividend during the following  January.  It is expected that none of the Funds'
distributions will qualify for the corporate dividends-received deduction.

     To the extent that a Fund's  dividends  distributed  to  shareholders  are
derived from interest  income exempt from federal income tax and are designated
as  "exempt-interest  dividends"  by a Fund,  they  will be  excludable  from a
shareholder's  gross income for federal income tax purposes.  Shareholders  who
are recipients of Social Security benefits should be aware that exempt-interest
dividends received from a Fund are includible in their "modified adjusted gross
income"  for  purposes  of  determining  the  amount  of such  Social  Security
benefits, if any, that are required to be included in their gross income.

     A  shareholder  of the Texas  Tax-Free  Income Fund should be aware that a
redemption  of shares  (including  any  exchange  into  another USAA Fund) is a
taxable event and, accordingly,  a capital gain or loss may be recognized. If a
shareholder receives an exempt-interest  dividend with respect to any share and
such share has been held for six months or less,  any loss on the redemption or
exchange  will be disallowed  to the extent of such  exempt-interest  dividend.
Similarly,  if a  shareholder  of the Fund receives a  distribution  taxable as
long-term  capital  gain with  respect  to shares  of the Fund and  redeems  or
exchanges  shares before he or she has held them for more than six months,  any
loss on the redemption or exchange (not otherwise disallowed as attributable to
an exempt-interest dividend) will be treated as long-term capital loss.

     The Funds may  invest in  private  activity  bonds.  Interest  on  certain
private  activity  bonds  issued  after  August  7,  1986,  is an  item  of tax
preference for purposes of the federal alternative minimum tax (AMT),  although
the interest  continues to be excludable  from gross income for other purposes.
AMT is a  supplemental  tax  designed to ensure that  taxpayers  pay at least a
minimum  amount of tax on their income,  even if they make  substantial  use of
certain tax deductions and  exclusions  (referred to as tax preference  items).
Interest from private activity bonds is one of the tax preference items that is
added to income from other  sources for the purposes of  determining  whether a
taxpayer  is  subject  to the AMT and the  amount  of any tax to be  paid.  For
corporate investors,  alternative minimum taxable income is increased by 75% of
the amount by which adjusted current earnings (ACE) exceeds alternative minimum
taxable  income  before  the  ACE  adjustment.  For  corporate  taxpayers,  all
tax-exempt  interest is considered in  calculating  the AMT as part of the ACE.
Prospective investors should consult their own tax advisers with respect to the
possible application of the AMT to their tax situation.

     Opinions  relating  to the  validity  of  tax-exempt  securities  and  the
exemption  of  interest  thereon  from  federal  income  tax  are  rendered  by
recognized  bond counsel to the issuers.  Neither the  Manager's nor the Funds'
counsel makes any review of the basis of such opinions.

                       TRUSTEES AND OFFICERS OF THE TRUST

The Board of Trustees of the Trust consists of seven Trustees who supervise the
business affairs of the Trust. Set forth below are the Trustees and officers of

(a)  Robert  G.  Davis,  Michael  J.C.  Roth,  and  John  W. Saunders,  Jr. are
     affiliated  with the Trust's  investment adviser,  IMCO, and, accordingly,
     receive no  remuneration  from  the Trust  or any  other  Fund of the USAA
     Family of Funds.

(b)  At March 31, 1999, the USAA Family of Funds  consisted of four  registered
     investment  companies offering 35 individual funds. Each Trustee presently
     serves as a Trustee or  Director  of each  investment  company in the USAA
     Family of Funds.  In addition,  Michael J.C.  Roth  presently  serves as a
     Trustee of USAA Life  Investment  Trust, a registered  investment  company
     advised by IMCO,  consisting  of seven funds  available to the public only
     through the purchase of certain  variable  annuity  contracts and variable
     life insurance policies offered by USAA Life Insurance  Company.  Mr. Roth
     receives no compensation as Trustee of USAA Life Investment Trust.

     All of the above Trustees are also  Trustees/Directors  of the other funds
within the USAA  Family of Funds.  No  compensation  is paid by any fund to any
Trustee/Director  who is a  director,  officer,  or  employee  of  IMCO  or its
affiliates.  No  pension or  retirement  benefits  are  accrued as part of fund
expenses.  The Trust  reimburses  certain  expenses of the Trustees who are not
affiliated  with the investment  adviser.  As of May 14, 1999, the officers and
Trustees of the Trust and their  families as a group owned  beneficially  or of
record less than 1% of the outstanding shares of the Trust.

     The following table  identifies all persons,  who as of May 14, 1999, held

                              THE TRUST'S MANAGER

As described  in the  Prospectus,  USAA  Investment  Management  Company is the
Manager  and  investment   adviser,   providing  services  under  the  Advisory
Agreement.  The Manager, a wholly owned indirect  subsidiary of United Services
Automobile   Association  (USAA),  a  large,   diversified  financial  services
institution, was organized in May 1970 and has served as investment adviser and
underwriter for USAA State Tax-Free Trust from its inception.

     In addition  to  managing  the  Trust's  assets,  the Manager  advises and
manages the investments for USAA and its affiliated  companies as well as those
of USAA Investment  Trust,  USAA Mutual Fund, Inc., USAA Tax Exempt Fund, Inc.;
and USAA Life Investment  Trust. As of the date of this SAI, total assets under
management   by  the  Manager  were   approximately   $40  billion,   of  which
approximately $26 billion were in mutual fund portfolios.

ADVISORY AGREEMENT

Under the  Advisory  Agreement,  the Manager  provides an  investment  program,
carries out the investment  policy,  and manages the portfolio  assets for each
Fund.  The  Manager  is  authorized,  subject  to the  control  of the Board of
Trustees of the Trust, to determine the selection,  amount,  and time to buy or
sell  securities for each Fund. In addition to providing  investment  services,
the  Manager  pays  for  office  space,  facilities,  business  equipment,  and
accounting  services (in addition to those  provided by the  Custodian) for the
Trust.  The Manager  compensates all personnel,  officers,  and Trustees of the
Trust if such persons are also employees of the Manager or its affiliates.  For
these  services under the Advisory  Agreement,  the Trust has agreed to pay the
Manager a fee computed as described  under FUND  MANAGEMENT in the  Prospectus.
Management fees are computed and accrued daily and payable monthly.

     Except for the services and facilities provided by the Manager,  the Funds
pay all other  expenses  incurred in their  operations.  Expenses for which the
Funds  are  responsible  include  taxes  (if  any);  brokerage  commissions  on
portfolio transactions (if any); expenses of issuance and redemption of shares;
charges of transfer agents, custodians, and dividend disbursing agents; cost of
preparing  and  distributing  proxy  material;  costs of printing and engraving
stock   certificates;   auditing  and  legal  expenses;   certain  expenses  of
registering  and  qualifying  shares  for sale;  fees of  Trustees  who are not
interested  persons  (not  affiliated)  of the  Manager;  costs of printing and
mailing the Prospectus, SAI, and periodic reports to existing shareholders; and
any other  charges or fees not  specifically  enumerated.  The Manager pays the
cost of printing and mailing copies of the Prospectus,  the SAI, and reports to
prospective shareholders.

     The Advisory Agreement will remain in effect until June 30, 2000, for each
Fund and will continue in effect from year to year  thereafter for each Fund as
long as it is approved at least  annually by a vote of the  outstanding  voting
securities  of such  Fund  (as  defined  by the  1940  Act) or by the  Board of
Trustees (on behalf of such Fund)  including a majority of the Trustees who are
not  interested  persons of the Manager or (otherwise  than as Trustees) of the
Trust,  at a meeting  called for the  purpose of voting on such  approval.  The
Advisory  Agreement  may be  terminated  at any time by either the Trust or the
Manager on 60 days'  written  notice.  It will  automatically  terminate in the
event of its assignment (as defined in the 1940 Act).

     From time to time the Manager may,  without prior notice to  shareholders,
waive all or any portion of fees or agree to reimburse  expenses  incurred by a
Fund. Any such waiver or reimbursement  may be terminated by the Manager at any
time without prior notice to shareholders.  The Manager has voluntarily  agreed
to limit each Fund's  annual  expenses to .50% of its ANA until August 1, 2000,
and will reimburse the Funds for all expenses in excess of the limitations.

     For the last three fiscal years, management fees were as follows:

                                          1997         1998        1999

   Texas Tax-Free Income Fund            $47,582      $76,602     $138,727
   Texas Tax-Free Money Market Fund      $25,483      $27,561     $ 32,937

     Because the Funds'  expenses  exceeded  the  Manager's  voluntary  expense
limitation,  the Manager did not receive any management fees for the last three
fiscal years with respect to the Texas Tax-Free Money Market Fund. With respect
to the Texas  Tax-Free  Income Fund, the Manager did not receive any management
fees for  1997.  For 1998 and 1999 the  Manager  did not  receive  $73,972  and
$101,891 respectively, in management fees to which it would have been entitled.
In  addition,  the Manager did not receive  reimbursement  for other  operating
expenses to which it would have been entitled as follows:

                                          1997         1998        1999

UNDERWRITER

The Trust has an  agreement  with the Manager for  exclusive  underwriting  and
distribution  of the Funds'  shares on a continuing  best efforts  basis.  This
agreement  provides that the Manager will receive no fee or other  compensation
for such distribution services.

TRANSFER AGENT

The  Transfer  Agent  performs  transfer  agent  services for the Trust under a
Transfer Agency Agreement.  Services include maintenance of shareholder account
records,  handling of communications  with  shareholders,  distribution of Fund
dividends,  and  production  of reports  with  respect to account  activity for
shareholders  and the  Trust.  For  its  services  under  the  Transfer  Agency
Agreement,  each Fund pays the Transfer Agent an annual fixed fee of $28.50 per
account. The fee is subject to change at any time.

     The fee to the Transfer Agent includes  processing of all transactions and
correspondence.  Fees are billed on a monthly basis at the rate of  one-twelfth
of the annual fee. In addition,  each Fund pays all  out-of-pocket  expenses of
the  Transfer  Agent and other  expenses  which are  incurred  at the  specific
direction of the Trust.

INDEPENDENT AUDITORS

KPMG LLP, 112 East Pecan,  Suite 2400,  San Antonio,  TX 78205,  is the Trust's
independent auditor. In this capacity, the firm is responsible for auditing the
annual financial statements of the Funds and reporting thereon.

                        CALCULATION OF PERFORMANCE DATA

Information regarding the total return and yield of each Fund is provided under
COULD THE VALUE OF YOUR INVESTMENT IN THESE FUNDS FLUCTUATE? in the Prospectus.
See VALUATION OF SECURITIES herein for a discussion of the manner in which each
Fund's price per share is calculated.

TOTAL RETURN

The Texas  Tax-Free  Income Fund may advertise  performance in terms of average
annual total return for 1-, 5-, and 10-year periods,  or for such lesser period
as the Fund has been in existence.  Average  annual total return is computed by
finding the average  annual  compounded  rates of return over the periods  that
would  equate the  initial  amount  invested  to the ending  redeemable  value,
according to the following formula:

                                P(1 + T)N = ERV

Where:    P =  a hypothetical initial payment of $1,000
          T =  average annual total return
          n =  number of years
        ERV =  ending redeemable value of a hypothetical $1,000 payment made at
               the beginning of the 1-, 5-, or  10-year  periods  at the end of
               the year or period

     The  calculation  assumes all charges are deducted from the initial $1,000
payment and assumes all dividends and distributions by such Fund are reinvested
at the price  stated in the  Prospectus  on the  reinvestment  dates during the
period and  includes  all  recurring  fees that are charged to all  shareholder
accounts.

     The date of  commencement of operations for the Texas Tax-Free Income Fund
was August 1, 1994. The Fund's average total returns for the following  periods
ended March 31, 1999, were:

              1 year .  . 5.00%          Since inception  . .8.75%

                                      21
<PAGE>
YIELD

The Texas Tax-Free  Income Fund may advertise  performance in terms of a 30-day
yield  quotation.  The 30-day  yield  quotation is computed by dividing the net
investment  income per share earned  during the period by the maximum  offering
price  per  share on the last day of the  period,  according  to the  following
formula:
                         Yield = 2[((a-b)/(cd)+1)^6 -1]

Where:   a  =  dividends and interest earned during the period
         b  =  expenses accrued for the period (net of reimbursement)
         c  =  the average daily number of shares outstanding during the period
               that were entitled to receive dividends
         d  =  the  maximum  offering  price per share  on the last  day of the
               period

     For purposes of the yield  calculation,  interest income is computed based
on the yield to maturity of each debt  obligation  in the Fund's  portfolio and
all recurring charges are recognized.

     The Fund's 30-day yield for the period ended March 31, 1999, was 4.79%.

YIELD - TEXAS TAX-FREE MONEY MARKET FUND

When the Texas Tax-Free Money Market Fund quotes a current annualized yield, it
is based on a specified recent seven-calendar-day period. It is computed by (1)
determining the net change,  exclusive of capital changes and income other than
investment income, in the value of a hypothetical  preexisting account having a
balance of one share at the  beginning  of the  period,  (2)  dividing  the net
change in account  value by the value of the  account at the  beginning  of the
base period to obtain the base  return,  then (3)  multiplying  the base period
return by 52.14 (365/7).  The resulting  yield figure is carried to the nearest
hundredth of one percent.

     The calculation includes (1) the value of additional shares purchased with
dividends on the original  share,  and dividends  declared on both the original
share  and  any  such  additional  shares  and  (2)  any  fees  charged  to all
shareholder  accounts,  in  proportion to the length of the base period and the
Fund's average account size.

     The capital changes  excluded from the  calculation  are realized  capital
gains and losses from the sale of securities  and unrealized  appreciation  and
depreciation.  The Fund's  effective  (compounded)  yield will be  computed  by
dividing the seven-day  annualized  yield as defined above by 365,  adding 1 to
the quotient,  raising the sum to the 365th power,  and  subtracting 1 from the
result.

     Current and effective  yields  fluctuate  daily and will vary with factors
such as  interest  rates and the  quality,  length of  maturities,  and type of
investments in the portfolio.

            Yield for 7-day Period ended March 31, 1999, was 2.89%.
       Effective Yield for 7-day Period ended March 31, 1999, was 2.93%.

TAX-EQUIVALENT YIELD

A  tax-exempt  mutual fund may  provide  more  "take-home"  income than a fully
taxable mutual fund after paying taxes.  Calculating a  "tax-equivalent  yield"
means converting a tax-exempt yield to a pretax-equivalent so that a meaningful
comparison can be made between a tax-exempt  municipal fund and a fully taxable
fund. The Texas  Tax-Free Money Market Fund may advertise  performance in terms
of a  tax-equivalent  yield based on the 7-day yield or effective yield and the
Texas  Tax-Free  Income  Fund may  advertise  performance  in terms of a 30-day
tax-equivalent yield.

     To calculate a  tax-equivalent  yield,  the Texas  investor  must know his
federal marginal income tax rate. The tax-equivalent  yield is then computed by
dividing  the  tax-exempt  yield  of a fund by the  complement  of the  federal
marginal tax rate. The complement,  for example, of a federal marginal tax rate
of 36.0% is 64.0%, that is (1.00-0.36= 0.64).

    Tax-Equivalent Yield = Tax-Exempt Yield / (1- Federal Marginal Tax Rate)

     Based on federal marginal tax rate of 36.0%, the tax-equivalent yields for
the Texas Tax-Free  Income and Texas Tax-Free Money Market Funds for the period
ended March 31, 1999, were 7.48% and 4.52%, respectively.

              APPENDIX A - TAX-EXEMPT SECURITIES AND THEIR RATINGS

TAX-EXEMPT SECURITIES

Tax-exempt  securities  generally include debt obligations issued by states and
their   political   subdivisions,   and  duly   constituted   authorities   and
corporations,  to obtain funds to construct,  repair or improve  various public
facilities such as airports,  bridges, highways,  hospitals,  housing, schools,
streets, and water and sewer works. Tax-exempt securities may also be issued to
refinance  outstanding  obligations  as well as to  obtain  funds  for  general
operating expenses and for loans to other public institutions and facilities.

     The two principal  classifications  of tax-exempt  securities are "general
obligations" and "revenue" or "special tax" bonds. General obligation bonds are
secured by the issuer's  pledge of its full faith,  credit and taxing power for
the payment of principal and interest. Revenue or special tax bonds are payable
only  from  the  revenues  derived  from a  particular  facility  or  class  of
facilities  or, in some cases,  from the proceeds of a special  excise or other
tax, but not from general tax revenues. The Funds may also invest in tax-exempt
private activity bonds,  which in most cases are revenue bonds and generally do
not have the pledge of the credit of the issuer.  The payment of the  principal
and  interest  on such  industrial  revenue  bonds is  dependent  solely on the
ability  of the  user of the  facilities  financed  by the  bonds  to meet  its
financial  obligations and the pledge, if any, of real and personal property so
financed as security for such payment. There are, of course, many variations in
the terms of, and the security underlying,  tax-exempt  securities.  Short-term
obligations  issued by states,  cities,  municipalities or municipal  agencies,
include Tax Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation
Notes, Construction Loan Notes, and Short-Term Notes.

     The yields of tax-exempt securities depend on, among other things, general
money market conditions,  conditions of the tax-exempt bond market, the size of
a particular  offering,  the maturity of the obligation,  and the rating of the
issue. The ratings of Moody's Investors  Service,  Inc.  (Moody's),  Standard &
Poor's Ratings Group (S&P),  Fitch IBCA, Inc. (Fitch),  Duff & Phelps LLC,  and
Thompson  BankWatch,  Inc.,  represent  their  opinions  of the  quality of the
securities rated by them. It should be emphasized that such ratings are general
and are not absolute  standards of quality.  Consequently,  securities with the
same maturity,  coupon, and rating may have different yields,  while securities
of the same  maturity and coupon but with  different  ratings may have the same
yield. It will be the  responsibility of the Manager to appraise  independently
the  fundamental  quality of the  tax-exempt  securities  included  in a Fund's
portfolio.

I.  LONG-TERM DEBT RATINGS:

MOODY'S INVESTOR SERVICES, INC.

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

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

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

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

NOTE:  MOODY'S APPLIES  NUMERICAL  MODIFIERS 1, 2, AND 3 IN EACH GENERIC RATING
CLASSIFICATION.  THE  MODIFIER 1  INDICATES  THAT THE  OBLIGATION  RANKS IN THE
HIGHER END OF ITS GENERIC RATING CATEGORY, THE MODIFIER 2 INDICATES A MID-RANGE
RANKING,  AND THE  MODIFIER  3  INDICATES  A  RANKING  IN THE LOWER END OF THAT
GENERIC RATING CATEGORY.

                                      23
<PAGE>
STANDARD & POOR'S RATINGS GROUP

AAA  An  obligation  rated AAA has the  highest  rating  assigned by Standard &
     Poor's.  The obligor's  capacity to meet its  financial  commitment on the
     obligation is extremely strong.

AA   An obligation rated AA differs from the highest rated issues only in small
     degree.  The obligor's  capacity to meet its  financial  commitment on the
     obligation is VERY STRONG.

A    An obligation  rated A is somewhat more susceptible to the adverse effects
     of changes in  circumstances  and economic  conditions than obligations in
     higher  rated  categories.  However,  the  obligor's  capacity to meet its
     financial commitment on the obligation is still STRONG.

BBB  An  obligation  rated BBB exhibits  adequate  capacity to pay interest and
     repay  principal.   However,   adverse  economic  conditions  or  changing
     circumstances  are  more  likely  to lead to a  weakened  capacity  of the
     obligor to meet its financial commitment on the obligation.

PLUS  (+) OR MINUS  (-):  THE  RATINGS  FROM AA TO BBB MAY BE  MODIFIED  BY THE
ADDITION  OF A PLUS OR MINUS SIGN TO SHOW  RELATIVE  STANDING  WITHIN THE MAJOR
RATING CATEGORIES.

FITCH IBCA, INC.

AAA  Highest credit  quality.  "AAA" ratings  denote the lowest  expectation of
     credit  risk.  They  are  assigned  only in case of  exceptionally  strong
     capacity for timely  payment of financial  commitments.  This  capacity is
     highly unlikely to be adversely affected by foreseeable events.

AA   Very high credit  quality.  "AA" ratings denote a very low  expectation of
     credit risk.  They  indicate  very strong  capacity for timely  payment of
     financial  commitments.  This capacity is not significantly  vulnerable to
     foreseeable events.

A    High credit quality.  "A" ratings denote a low expectation of credit risk.
     The capacity for timely  payment of financial  commitments  is  considered
     strong. This capacity may, nevertheless,  be more vulnerable to changes in
     circumstances  or in  economic  conditions  than is the  case  for  higher
     ratings.

BBB  Good credit quality.  "BBB" ratings indicate that there is currently a low
     expectation  of credit risk.  The capacity for timely payment of financial
     commitments is considered  adequate,  but adverse changes in circumstances
     and in economic  conditions are more likely to impair this capacity.  This
     is the lowest investment-grade category.

PLUS AND MINUS  SIGNS ARE USED WITH A RATING  SYMBOL TO INDICATE  THE  RELATIVE
POSITION OF A CREDIT WITHIN THE RATING CATEGORY. PLUS AND MINUS SIGNS, HOWEVER,
ARE NOT USED IN THE AAA CATEGORY.

DUFF & PHELPS, LLC

AAA  Highest  credit  quality.  The risk  factors  are  negligible,  being only
     slightly more than for risk-free U.S. Treasury debt.

AA   High credit quality. Protection factors are strong. Risk is modest but may
     vary slightly from time to time because of economic conditions.

A    Protection  factors are average but  adequate.  However,  risk factors are
     more variable and greater in periods of economic stress.

BBB  Below  average  protection  factors but still  considered  sufficient  for
     prudent  investment.  Considerable  variability  in risk  during  economic
     cycles.

2. SHORT-TERM DEBT RATINGS:

MOODY'S STATE AND TAX-EXEMPT NOTES

MIG-1/VMIG1  This  designation  denotes best quality.  There is present  strong
             protection by established cash flows,  superior liquidity support,
             or demonstrated broad-based access to the market for refinancing.

MIG-2/VMIG2  This designation  denotes high quality.  Margins of protection are
             ample although not so large as in the preceding group.

MOODY'S COMMERCIAL PAPER

Prime-1  Issuers rated  Prime-1 (or  supporting  institutions)  have a superior
         ability for  repayment of senior  short-term  promissory  obligations.
         Prime-1 repayment capacity will normally be evidenced by the following
         characteristics:

         * Leading market positions in well-established industries.
         * High rates of return on funds employed.

                                      24
<PAGE>
         * Conservative  capitalization  structures  with moderate  reliance on
           debt and ample asset protection.
         * Broad  margins in earning  coverage of fixed  financial  charges and
           high internal cash generation.
         * Well-established  access to a range of financial markets and assured
           sources of alternate liquidity.

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

S&P TAX-EXEMPT NOTES

SP-1 Strong  capacity to pay  principal  and  interest.  Issues  determined  to
     possess very strong characteristics are given a plus (+) designation.

SP-2 Satisfactory   capacity  to  pay  principal   and   interest,   with  some
     vulnerability  to adverse  financial and economic changes over the term of
     the notes.

S&P COMMERCIAL PAPER

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

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

FITCH'S COMMERCIAL PAPER, CERTIFICATES OF DEPOSIT AND TAX-EXEMPT NOTES

F1   Highest  credit  quality.  Indicates  the  strongest  capacity  for timely
     payment  of  financial  commitments;  may have an added "+" to denote  any
     exceptionally strong credit features.

F2   Good  credit  quality.  A  satisfactory  capacity  for  timely  payment of
     financial commitments,  but the margin of safety is not as great as in the
     case of the higher ratings.

F3   Fair  credit  quality.  The  capacity  for  timely  payment  of  financial
     commitments is adequate;  however,  near-term adverse changes could result
     in a reduction to non-investment grade.

DUFF & PHELPS COMMERCIAL PAPER

D-1+ Highest  certainty  of timely  payment.  Short-term  liquidity,  including
     internal operating factors and/or access to alternative  sources of funds,
     is  outstanding,   and  safety  is  just  below  risk-free  U.S.  Treasury
     short-term obligations.

D-1  Very high certainty of timely payment. Liquidity factors are excellent and
     supported by good fundamental protection factors. Risk factors are minor.

D-1- High  certainty  of timely  payment.  Liquidity  factors  are  strong  and
     supported by good fundamental  protection  factors.  Risk factors are very
     small.

D-2  Good  certainty  of  timely   payment.   Liquidity   factors  and  company
     fundamentals  are sound.  Although ongoing funding needs may enlarge total
     financing  requirements,  access to capital  markets is good. Risk factors
     are small.

THOMPSON BANKWATCH, INC.

TBW-1 The highest category; indicates a very high likelihood that principal and
      interest will be paid on a timely basis.

TBW-2 The second highest category;  while the degree of safety regarding timely
      repayment of principal  and  interest is strong,  the relative  degree of
      safety is not as high as for issues rated TBW-1.

TBW-3 The lowest investment-grade category; indicates that while the obligation
      is more susceptible to adverse  developments (both internal and external)
      than those with higher  ratings,  the capacity to service  principal  and
      interest in a timely fashion is considered adequate.

                       APPENDIX C - DOLLAR-COST AVERAGING

Dollar-cost  averaging is a systematic  investing method,  which can be used by
investors as a disciplined technique for investing.  A fixed amount of money is
invested in a security (such as a stock or mutual fund) on a regular basis over
a period of time,  regardless  of whether  securities  markets are moving up or
down.

     This  practice  reduces  average  share costs to the investor who acquires
more shares in periods of lower  securities  prices and fewer shares in periods
of higher prices.

     While  dollar-cost  averaging does not assure a profit or protect  against
loss in declining markets, this investment strategy is an effective way to help
calm the effect of fluctuations in the financial markets.  Systematic investing
involves  continuous  investment in securities  regardless of fluctuating price
levels of such securities. Investors should consider their financial ability to
continue purchases through periods of low and high price levels.

     As the following chart  illustrates,  dollar-cost  averaging tends to keep
the overall cost of shares lower.  This example is for  illustration  only, and
different trends would result in different average costs.
