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]
Look for this symbol throughout the Prospectus. We use it to mark more detailed
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.

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:

  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%.

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,  the prices of
       bonds fall and when interest rates fall, bond prices generally 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.

       [CAUTION LIGHT GRAPHIC]
    Q  What is Call Risk?

    A  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]
    Q  What is structural risk?

    A  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."

                                      11
<PAGE>

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

                                      12
<PAGE>

       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
       which 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.

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

    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.

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

                                      13
<PAGE>

       * 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.

    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

                                      14
<PAGE>

       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; or 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; or if unrated by these agencies, we must determine that
       the securities are of equivalent investment quality.

       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.

                                      15
<PAGE>

    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;

       * 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.

                                      16
<PAGE>

    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, Inc.; 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.

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  $___  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.

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
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 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  delay in the  effective  date of your purchase of up to
four to six weeks.  Furthermore,  a bank charge may be assessed in the clearing
process, which will be deducted from the amount of the purchase.

Redemption of Shares

You may redeem Fund shares by any of the methods described below on any day the

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.

instructions.  Before any  discussion  regarding  your  account,  the following

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 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 22.

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).

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.

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.

                                      25
<PAGE>

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.

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 that 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.  The Funds 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. 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 100% 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 expect to have our systems
ready for the Year 2000 by mid-1999. 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 any 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) which 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.

LIQUIDITY

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 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.

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 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.

[CAUTION LIGHT GRAPHIC]
Look for this symbol throughout the Prospectus. We use it to mark more detailed
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 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

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.

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:

                                                 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%.

FUND INVESTMENTS

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,  the prices of
       bonds fall and when interest rates fall, bond

                                      10
<PAGE>

       prices  generally  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.

       [CAUTION LIGHT GRAPHIC]
    Q  What is Call Risk?

    A  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]
    Q  What is structural risk?

    A  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 or that we
       will not be able to

                                      11
<PAGE>

       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
       which 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.

                                      12
<PAGE>

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

    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  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

                                      14
<PAGE>

       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; or 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; or if unrated by these agencies, we must determine that
       the securities are of equivalent investment quality.

       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

                                      15
<PAGE>

       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.;
       * Duff & Phelps, Inc.; and
       * Thompson BankWatch, Inc.

                                      16
<PAGE>

    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  $___  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

                                      19
<PAGE>

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 33. 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 33 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 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.

                                      20
<PAGE>

This will avoid a potential  delay in the effective date of your purchase of up
to four  to six  weeks.  Furthermore,  a bank  charge  may be  assessed  in the
clearing process, which will be deducted from the amount of the purchase.

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

be liable for any losses due to unauthorized or fraudulent

                                      22

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

you were issued stock  certificates  for your shares,  redemption by telephone,
fax, or telegram is not available.

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

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).

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

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
advisors 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 expect to have our systems
ready for the Year 2000 by mid-1999. 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 any 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) which 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.

LIQUIDITY

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
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

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

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.

                                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  that 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. Florida provides an exemption for shares in
an investment fund if the Fund's  portfolio of assets consists solely of assets
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  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. If shares of
the Funds are subject to the Florida intangible  personal property tax, because
less than 100% 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.

The Board of Directors of the Company consists of seven Directors who supervise

- ---------------
(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.

     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   $__  billion,   of  which
approximately $__ 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.

                                      16

     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 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%

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

                                      18
<PAGE>

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

     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

                                      19
<PAGE>

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 Inc., 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.

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.

                                      20
<PAGE>

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, INC.

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

                                      21
<PAGE>

           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.

                            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

     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.

                                       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 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

                                       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 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
<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
      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

                                       7
<PAGE>

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  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,

                                       8
<PAGE>

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.

     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

                                       9
<PAGE>

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

                                      10
<PAGE>

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.

     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

                                      11
<PAGE>

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 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.

                                      12
<PAGE>

     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.

     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

                                      13
<PAGE>

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 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.

                                      14
<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.

                                      15
<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.

     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
the Trust, and their respective  offices and principal  occupations  during the
last five years.  Unless otherwise  indicated,  the business address of each is
9800 Fredericksburg Road, San Antonio, TX 78288.

     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'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   $__  billion,   of  which
approximately $__ 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.

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 Inc., 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, INC.

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.

                                      24
<PAGE>

           *   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.

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.

Item 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND

          Information pertaining  to  persons  controlled  by  or  under common
          control with  Registrant is hereby  incorporated  by reference to the
          section captioned "Fund Management" in the Prospectus and the section
          captioned  "Trustees  and  Officers of the Trust" in the Statement of
          Additional Information.

Item 25.  INDEMNIFICATION

          Protection for the liability of the adviser and  underwriter  and for
          the officers and  trustees  of  the  Registrant  is  provided  by two
          methods:

          (a) THE TRUSTEE AND OFFICER LIABILITY POLICY. This policy  covers all
              losses  incurred  by  the   Registrant,   its   adviser  and  its
              underwriter  from  any  claim  made  against  those  entities  or
              persons during  the  policy  period by any shareholder  or former
              shareholder of any Fund by reason of any alleged  negligent  act,
              error or omission committed in connection with the administration
              of the  investments  of  said  Registrant or in  connection  with
              the sale or redemption of shares issued by said  Registrant.  The
              Trust will not pay for such insurance to the extent that  payment
              therefor is in violation of the Investment Company Act of 1940 or
              the Securities Act of 1933.

          (b) INDEMNIFICATION  PROVISIONS  UNDER AGREEMENT AND  DECLARATION OF
              TRUST.   Under  Article  VI  of  the  Registrant's  Agreement and
              Declaration  of Trust,  each of its  Trustees and officers or any
              person serving at the Registrant's request as directors, officers
              or  trustees of another organization in which the  Registrant has
              any interest as a shareholder, creditor  or  otherwise ( "Covered
              Person") shall be indemnified  against all liabilities, including
              but not limited to amounts  paid in  satisfaction  of  judgments,
              in compromise or as fines and penalties, and expenses,  including
              reasonable  accountants'  and  counsel  fees,  incurred  by  any
              Covered Person in connection with  the defense or  disposition of
              any action, suit or other proceeding, whether civil  or criminal,
              before  any court or administrative or legislative body, in which
              such covered  Person  may be or may have been involved as a party
              or  otherwise  or with which such person may be or may have  been
              threatened,  while in office or  thereafter,  by reason of  being
              or having been such an officer, director or trustee, except with
              respect to any matter as to which it  has  been  determined  that
              such Covered Person  had  acted  with  willful  misfeasance,  bad
              faith,  gross  negligence  or reckless  disregard of  the  duties
              involved in the conduct of such Covered  Person's  office  (such
              conduct   referred  to   hereafter  as  "Disabling  Conduct").  A
              determination   that   the   Covered   Person  is   entitled  to
              indemnification  may be  made  by (i) a final  decision  on  the
              merits by a court or other body before  whom the  proceeding  was
              brought that the person  to be  indemnified  was not  liable  by
              reason of  Disabling Conduct, (ii)  dismissal of  a  court action
              or an  administrative  proceeding  against a Covered  Person  for
              insufficiency  of  evidence  of  Disabling  Conduct,  or  (iii) a
              reasonable  determination,  based  upon a  review  of the  facts,
              that the  Covered  Person  was not  liable by reason of Disabling
              Conduct  by (a) a vote of a  majority  of a  quorum  of Trustees
              who  are  neither  "interested  persons"  of  the  Registrant  as
              defined in section  2(a)(19) of the 1940 Act nor  parties  to the
              proceeding, or (b) an independent  legal  counsel  in  a  written
              opinion.

              Expenses,  including  accountants and counsel fees so incurred by
              any  such   Covered   Person  (but  excluding  amounts  paid  in
              satisfaction   of  judgments,  in  compromise  or  as  fines  or
              penalties), may be paid from time to time from funds attributable

                                     c-3
<PAGE>

              to the Fund of the Registrant in question in advance of the final
              disposition of any such action, suit or proceeding, provided that
              the Covered Person shall have  undertaken to repay the amounts so
              paid  to  the  Fund  of  the  Registrant  in  question  if  it is
              ultimately  determined that  indemnification  of such expenses is
              not  authorized  under this Article VI and (i) the Covered Person
              shall  have  provided  security  for such  undertaking,  (ii) the
              Registrant  shall be insured  against losses arising by reason of
              any  lawful  advances,  or (iii) a  majority  of a quorum  of the
              disinterested Trustees who are not a party to the proceeding,  or
              an  independent  legal counsel in a written  opinion,  shall have
              determined,  based on a review  of  readily  available  facts (as
              opposed  to full  trial-type  inquiry),  that  there is reason to
              believe that the Covered Person ultimately will be found entitled
              to indemnification.

              As to any matter disposed of by a compromise  payment by any such
              Covered Person pursuant to a consent decree or otherwise, no such
              indemnification either for said payment or for any other expenses
              shall be provided unless such  indemnification  shall be approved
              (a) by a  majority  of the  disinterested  Trustees  who  are not
              parties to the proceeding or (b) by an independent  legal counsel
              in a written opinion. Approval by the Trustees pursuant to clause
              (a) or by independent  legal counsel pursuant to clause (b) shall
              not prevent the  recovery  from any Covered  Person of any amount
              paid  to such  Covered  Person  in  accordance  with  any of such
              clauses as indemnification if such Covered Person is subsequently
              adjudicated  by a court of  competent  jurisdiction  to have been
              liable to the Registrant or its shareholders by reason of willful
              misfeasance, bad faith, gross negligence or reckless disregard of
              the  duties  involved  in the  conduct of such  Covered  Person's
              office.

              Insofar as  indemnification  for  liabilities  arising  under the
              Securities Act of 1933 may be permitted to trustees, officers and
              controlling   persons   of  the   Registrant   pursuant   to  the
              Registrant's Agreement and Declaration of the Trust or otherwise,
              the  Registrant  has been  advised  that,  in the  opinion of the
              Securities  and  Exchange  Commission,  such  indemnification  is
              against public policy as expressed in the Act and is,  therefore,
              unenforceable.  In the  event  that a claim  for  indemnification
              against  such   liabilities   (other  than  the  payment  by  the
              Registrant of expenses incurred or paid by a trustee,  officer or
              controlling person of the Registrant in the successful defense of
              any action,  suit or  proceeding)  is  asserted by such  trustee,
              officer or controlling  person in connection  with the securities
              being registered, then the Registrant will, unless in the opinion
              of its  counsel  the  matter has been  settled  by a  controlling
              precedent,  submit  to a court of  appropriate  jurisdiction  the
              question  of  whether  indemnification  by it is  against  public
              policy as  expressed in the Act and will be governed by the final
              adjudication of such issue.

under a master  revolving  credit  facility (the  "Facility").  USAA Investment
Management  Company is the Manager and  Investment  Advisor of each Fund.  This
Agreement replaces in its entirety that certain Facility Agreement Letter dated
January 13, 1998,  between the  Borrowers  and CAPCO.  CAPCO and the  Borrowers
hereby agree as follows:

       1.  AMOUNT.  The  aggregate  principal  amount of the Loans which may be
advanced  under this Facility  shall not exceed,  at any one time  outstanding,
Five Hundred Million Dollars ($500,000,000).  The aggregate principal amount of
the Loans which may be borrowed by a Borrower  for the benefit of a  particular
Fund under this Facility shall not exceed the borrowing  limit (the  "Borrowing
Limit")  on  borrowings  applicable  to such Fund,  as set forth on  Schedule A
hereto.

       2. PURPOSE AND  LIMITATIONS  ON  BORROWINGS.  Each Borrower will use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the Fund for whose  benefit it is  borrowing  in  accordance  with such  Fund's
Borrowing Limit (Schedule A) and prospectus in effect at the time of such Loan.
Portfolio  securities  may not be  purchased  by a Fund  while  there is a Loan
outstanding  under the Facility or any other facility,  if the aggregate amount
of such Loan and any other  such loan  exceeds  5% of the total  assets of such
Fund.

<PAGE>

       3.  BORROWING  RATE AND  MATURITY  OF LOANS.  CAPCO may make  Loans to a
Borrower and the principal  amount of the Loans  outstanding  from time to time
shall  bear  interest  at a rate per  annum  equal  to the rate at which  CAPCO
obtains  funding  in the  capital  markets.  Interest  on the  Loans  shall  be
calculated  on the basis of a year of 360 days and the actual days  elapsed but
shall not exceed the highest lawful rate.  Each loan will be for an established
number  of  days   agreed   upon  by  the   applicable   Borrower   and  CAPCO.
Notwithstanding the above, all Loans to a Borrower shall be made available at a
rate per annum equal to the rate at which CAPCO would make loans to  affiliates
and  subsidiaries.  Further,  if the  CAPCO  rate  exceeds  the rate at which a
Borrower could obtain funds pursuant to the NationsBank,  N.A.  ("NationsBank")
364-day committed  $100,000,000 Master Revolving Credit Facility,  the Borrower
will in the absence of predominating  circumstances,  borrow from  NationsBank.
Any past due principal  and/or  accrued  interest shall bear interest at a rate
per annum equal to the  aggregate of the Federal Funds Rate plus 1 percent (100
basis points) and shall be payable on demand.

       4. ADVANCES, PAYMENTS,  PREPAYMENTS AND READVANCES. Upon each Borrower's
request,  and subject to the terms and conditions  contained herein,  CAPCO may
make Loans to each Borrower on behalf of and for the benefit of its  respective
Fund(s) during the Facility  Period,  and each Borrower may at CAPCO's sole and
absolute  discretion,  borrow,  repay and reborrow funds  hereunder.  The Loans
shall be evidenced by a duly executed and delivered Master Grid Promissory Note
in the form of EXHIBIT A. Each Loan  shall be in an  aggregate  amount not less
than One Hundred Thousand United States Dollars (U.S.  $100,000) and increments
of One Thousand United States Dollars (U.S. $1,000) in excess thereof.  Payment
of principal and interest due with respect to each Loan shall be payable at the
maturity of such Loan and shall be made in funds immediately available to CAPCO
prior to 2 p.m.  San Antonio  time on the day such  payment is due, or as CAPCO
shall  otherwise  direct  from  time to time  and,  subject  to the  terms  and
conditions  hereof,  may  be  repaid  with  the  proceeds  of a  new  borrowing
hereunder. Notwithstanding any provision of this Agreement to the contrary, all
Loans, accrued but unpaid interest and other amounts payable hereunder shall be
due and payable upon  termination of the Facility  (whether by  acceleration or
otherwise).

       5. FACILITY FEE. As this Facility is uncommitted,  no facility fee shall
be charged by CAPCO.

       6.  OPTIONAL  TERMINATION.  The  Borrowers  shall have the right upon at
least three (3) business days prior written  notice to CAPCO,  to terminate the
Facility.

       7. MANDATORY TERMINATION OF THE FACILITY. The Facility,  unless extended
by written  amendment,  shall  automatically  terminate  on the last day of the
Facility Period and any Loans then outstanding  (together with accrued interest
thereon and any other amounts owing hereunder) shall be due and payable on such
date.

<PAGE>

       8. UNCOMMITTED FACILITY.  The Borrowers acknowledge that the Facility is
an  uncommitted  facility and that CAPCO shall have no  obligation  to make any
Loan requested during the Facility Period under this Agreement.  Further, CAPCO
shall not make any Loan if this Facility has been  terminated by the Borrowers,
or if at the time of a  request  for a Loan by a  Borrower  (on  behalf  of the
applicable  Fund(s)) there exists any Event of Default or condition which, with
the passage of time or giving of notice, or both, would constitute or become an
Event of Default with respect to such Borrower (or such applicable Fund(s)).

       9. LOAN  REQUESTS.  Each request for a Loan (each a "Borrowing  Notice")
shall be in writing by the applicable Borrower(s), except that such Borrower(s)
may make an oral  request  (each an "Oral  Request")  provided  that  each Oral
Request  shall be followed by a written  Borrowing  Notice  within one business
day. Each Borrowing  Notice shall specify the following  terms ("Terms") of the
requested  Loan:  (i) the date on which such Loan is to be disbursed,  (ii) the
principal amount of such Loan,  (iii) the Borrower(s)  which are borrowing such
Loan and the  amount of such Loan to be  borrowed  by each  Borrower,  (iv) the
Funds for whose  benefit the loan is being  borrowed and the amount of the Loan
which is for the benefit of each such Fund, and (v) the requested maturity date
of the Loan.  Each  Borrowing  Notice  shall also set forth the total assets of
each Fund for whose  benefit a portion of the Loan is being  borrowed as of the
close of business on the day  immediately  preceding the date of such Borrowing
Notice.  Borrowing notices shall be delivered to CAPCO by 9:00 a.m. San Antonio
time on the day the Loan is requested to be made.

Each  Borrowing  Notice  shall  constitute  a  representation  to  CAPCO by the
applicable  Borrower(s)  that  all of the  representations  and  warranties  in
Section  12 hereof  are true and  correct  as of such date and that no Event of
Default or other  condition which with the passage of time or giving of notice,
or both, would result in an Event of Default, has occurred or is occurring.

       10.  CONFIRMATIONS;  CREDITING OF FUNDS; RELIANCE BY CAPCO. Upon receipt
by CAPCO of a Borrowing Notice:

               (a)  CAPCO  shall  provide  each  applicable   Borrower  written
       confirmation  of the Terms of such Loan via  facsimile or  telecopy,  as
       soon as reasonably practicable;  provided,  however, that the failure to
       do so shall not affect the obligation of any such Borrower;

               (b) CAPCO shall make such Loan in  accordance  with the Terms by
       transfer  of the Loan  amount in  immediately  available  funds,  to the
       account of the applicable  Borrower(s) as specified in EXHIBIT B to this
       Agreement or as such Borrower(s)  shall otherwise  specify to CAPCO in a
       writing signed by an Authorized Individual (as defined in Section 11) of
       such Borrower(s); and

<PAGE>

               (c) CAPCO  shall  make  appropriate  entries  on the Note or the
       records of CAPCO to reflect  the Terms of the Loan;  provided,  however,
       that the  failure  to do so  shall  not  affect  the  obligation  of any
       Borrower.

               (d)  CAPCO  shall be  entitled  to rely  upon and act  hereunder
       pursuant to any Oral Request which it  reasonably  believes to have been
       made by the applicable Borrower through an Authorized Individual. If any
       Borrower  believes that the  confirmation  relating to any Loan contains
       any error or discrepancy from the applicable Oral Request, such Borrower
       will promptly notify CAPCO thereof.

       11.  BORROWING  RESOLUTIONS  AND  OFFICERS'  CERTIFICATES.  Prior to the
making  of any Loan  pursuant  to this  Agreement,  the  Borrowers  shall  have
delivered  to  CAPCO  (a) the  duly  executed  Note,  (b)  Resolutions  of each
Borrower's Trustees or Board of Directors authorizing such Borrower to execute,
deliver and perform  this  Agreement  and the Note on behalf of the  applicable
Funds,  (c) an Officer's  Certificate  in  substantially  the form set forth in
EXHIBIT  D to this  Agreement,  authorizing  certain  individuals  ("Authorized
Individuals"),  to take on behalf of each Borrower (on behalf of the applicable
Funds) actions contemplated by this Agreement and the Note, and (d) the Opinion
of Counsel to USAA Investment  Management  Company,  Manager and Advisor to the
Borrowers, with respect to such matters as CAPCO may reasonably request .

       12.  REPRESENTATIONS  AND WARRANTIES.  In order to induce CAPCO to enter
into this Agreement and to make the Loans provided for hereunder, each Borrower
hereby  makes with  respect to itself,  and as may be  relevant,  the series of
Funds comprising such Borrower,  the following  representations and warranties,
which shall survive the execution and delivery hereof and of the Note:

               (a) ORGANIZATION,  STANDING,  ETC. The Borrower is a corporation
       or trust duly organized,  validly  existing,  and in good standing under
       applicable state laws and has all requisite corporate or trust power and
       authority to carry on its  respective  businesses  as now  conducted and
       proposed to be  conducted,  to enter into this  Agreement  and all other
       documents  to be  executed  by it in  connection  with the  transactions
       contemplated hereby, to issue and borrow under the Note and to carry out
       the terms hereof and thereof;

               (b)  FINANCIAL  INFORMATION;  DISCLOSURE,  ETC. The Borrower has
       furnished CAPCO with certain financial  statements of such Borrower with
       respect to itself and the applicable  Funds, all of which such financial
       statements  have been prepared in  accordance  with  generally  accepted
       accounting  principles  applied on a consistent basis and fairly present
       the  financial  position and results of  operations of such Borrower and
       the applicable Funds on the dates and for the periods indicated. Neither
       this Agreement nor any financial statements,  reports or other documents
       or  certificates  furnished to CAPCO by such Borrower or the  applicable
       Funds in connection with the  transactions  contemplated  hereby contain
       any untrue  statement  of a material  fact or omit to state any material
       fact  necessary to make the  statements  contained  herein or therein in
       light of the circumstances when made not misleading;

<PAGE>

               (c)  AUTHORIZATION;   COMPLIANCE  WITH  OTHER  INSTRUMENTS.  The
       execution,  delivery and performance of this Agreement and the Note, and
       borrowings  hereunder,  have  been  duly  authorized  by  all  necessary
       corporate  or trust  action of the  Borrower  and will not result in any
       violation of or be in conflict  with or  constitute a default  under any
       term of the charter,  by-laws or trust agreement of such Borrower or the
       applicable  Funds,  or of any  borrowing  restrictions  or prospectus or
       statement of additional  information  of such Borrower or the applicable
       Funds,  or  of  any  agreement,  instrument,  judgment,  decree,  order,
       statute, rule or governmental regulation applicable to such Borrower, or
       result in the creation of any mortgage, lien, charge or encumbrance upon
       any of the properties or assets of such Borrower or the applicable Funds
       pursuant to any such term. The Borrower and the applicable Funds are not
       in violation of any term of their respective  charter,  by-laws or trust
       agreement,  and  such  Borrower  and  the  applicable  Funds  are not in
       violation of any material  term of any  agreement or instrument to which
       they are a party,  or to the best of such Borrower's  knowledge,  of any
       judgment,  decree,  order,  statute,  rule  or  governmental  regulation
       applicable to them;

               (d) SEC COMPLIANCE. The Borrower and the applicable Funds are in
       compliance  in  all  material   respects  with  all  federal  and  state
       securities  or similar  laws and  regulations,  including  all  material
       rules,  regulations  and  administrative  orders of the  Securities  and
       Exchange Commission (the "SEC") and applicable Blue Sky authorities. The
       Borrower  and the  applicable  Funds are in  compliance  in all material
       respects  with all of the  provisions of the  Investment  Company Act of
       1940,  and such  Borrower  has filed all  reports  with the SEC that are
       required of it or the applicable Funds;

               (e) LITIGATION.  There is no action,  suit or proceeding pending
       or, to the best of the  Borrower's  knowledge,  threatened  against such
       Borrower or the  applicable  Funds in any court or before any arbitrator
       or  governmental  body which seeks to restrain  any of the  transactions
       contemplated by this Agreement or which, if adversely determined,  could
       have a material  adverse effect on the assets or business  operations of
       such  Borrower or the  applicable  Funds or the ability of such Borrower
       and the applicable Funds to pay and perform their obligations  hereunder
       and under the Notes;

               (f) BORROWERS'  RELATIONSHIP  TO FUNDS.  The assets of each Fund
       for whose  benefit  Loans are  borrowed by the  applicable  Borrower are
       subject  to and  liable  for such  Loans and are  available  (except  as
       subordinated to borrowings under the NationsBank  committed facility) to
       the applicable Borrower for the repayment of such Loans; and

               (G) YEAR 2000  PREPAREDNESS.  Each  Borrower has (i) initiated a
       review and  assessment  of all areas within its business and  operations
       (including  those  affected by suppliers,  vendors and  customers)  that
       could be  adversely  affected by the "Year 2000  Problem"  (that is, the
       risk that computer  applications  used by such Borrower may be unable to
       recognize  and  perform  properly  date-sensitive   functions  involving
       certain  dates  prior to and any date after  December  31,  1999),  (ii)
       developed a plan and timeline for  addressing the Year 2000 Problem on a
       timely basis, and (iii) to date, implemented that

<PAGE>

       plan in accordance  with that  timetable.  Based on the foregoing,  such
       Borrower  reasonably  believes that all computer  applications  that are
       material to its business and  operations  are  reasonably  expected on a
       timely basis to be able to perform properly date-sensitive functions for
       all dates  before  and after  January  1, 2000  (that is, be "Year  2000
       compliant"),  except to the  extent  that a  failure  to do so could not
       reasonably be expected to have a material  adverse  effect on the assets
       or business  operations of such Borrower or the applicable  Funds or the
       ability of such  Borrower  and the  applicable  Funds to pay and perform
       their obligations hereunder and under the Note.

       13.  AFFIRMATIVE  COVENANTS  OF THE  BORROWERS.  Until  such time as all
amounts of principal  and  interest due to CAPCO by a Borrower  pursuant to any
Loan made to such Borrower is irrevocably  paid in full, and until the Facility
is terminated, such Borrower (for itself and on behalf of its respective Funds)
agrees:

               (a) To  deliver  to CAPCO as soon as  possible  and in any event
       within  ninety  (90)  days  after  the end of each  fiscal  year of such
       Borrower and the applicable Funds, Statements of Assets and Liabilities,
       Statements of Operations and Statements of Changes in Net Assets of each
       applicable  Fund for such fiscal year,  as set forth in each  applicable
       Fund's Annual Report to shareholders  together with a calculation of the
       maximum  amount  which  each  applicable  Fund  could  borrow  under its
       Borrowing Limit as of the end of such fiscal year;

               (b) To  deliver to CAPCO as soon as  available  and in any event
       within seventy-five (75) days after the end of each semiannual period of

       Liabilities,  Statement of Operations  and  Statements of Changes in Net
       Assets of each applicable Fund as of the end of such semiannual  period,
       as set forth in each applicable Funds Semiannual Report to shareholders,
       together with a calculation of the maximum amount which each  applicable
       Fund  could  borrow  under  its  Borrowing  Limit  at the  end  of  such
       semiannual period;

               (c) To deliver to CAPCO prompt  notice of the  occurrence of any
       event or  condition  which  constitutes,  or is likely  to result  in, a
       change in such Borrower or any applicable Fund which could reasonably be
       expected to materially  adversely  affect the ability of any  applicable
       Fund to  promptly  repay  outstanding  Loans made for its benefit or the
       ability of such Borrower to perform its obligations under this Agreement
       or the Note;

               (d) To do, or cause to be done, all things necessary to preserve
       and keep in full force and effect the  corporate  or trust  existence of
       such Borrower and all permits,  rights and privileges  necessary for the
       conduct of its  businesses  and to comply in all material  respects with
       all  applicable  laws,   regulations  and  orders,   including   without
       limitation, all rules and regulations promulgated by the SEC;

<PAGE>

               (e) To promptly notify CAPCO of any litigation, threatened legal
       proceeding or  investigation  by a  governmental  authority  which could
       materially  affect the ability of such Borrower or the applicable  Funds
       to promptly  repay the  outstanding  Loans or  otherwise  perform  their
       obligations hereunder;

               (f) In the event a Loan for the benefit of a particular  Fund is
       not repaid in full  within 10 days  after the date it is  borrowed , and
       until  such Loan is repaid in full,  to  deliver  to CAPCO,  within  two
       business  days  after  each  Friday  occurring  after  such 10th day,  a
       statement setting forth the total assets of such Fund as of the close of
       business on each such Friday; and

               (g) Upon the  request  of CAPCO  which may be made by CAPCO from
       time to time in the event  CAPCO in good faith  believes  that there has
       been a material  adverse  change in the capital  markets  generally,  to
       deliver  to CAPCO,  within two  business  days  after  such  request,  a
       statement  setting forth the total assets of each Fund for whose benefit
       a Loan is outstanding on the date of such request.

       14. NEGATIVE COVENANTS OF THE BORROWERS.  Until such time as all amounts
of principal and interest due to CAPCO by a Borrower  pursuant to any Loan made
to such  Borrower  is  irrevocably  paid in full,  and  until the  Facility  is
terminated,  such Borrower (for itself and on behalf of its  respective  Funds)
agrees:

               (a) Not to incur any indebtedness for borrowed money (other than
       pursuant  to the One Hundred  Million  Dollar  ($100,000,000)  committed
       Master Revolving Credit Facility with NationsBank, the Two Hundred Fifty
       Million Dollar ($250,000,000) committed Master Revolving Credit Facility
       with CAPCO and for  overdrafts  incurred at the  custodian  of the Funds
       from time to time in the normal  course of  business)  except the Loans,
       without the prior  written  consent of CAPCO,  which consent will not be
       unreasonably withheld; and

               (b) Not to  dissolve or  terminate  its  existence,  or merge or
       consolidate   with  any  other   person  or  entity,   or  sell  all  or
       substantially  all of its  assets in a single  transaction  or series of
       related  transactions  (other than assets  consisting of margin  stock),
       each without the prior written consent of CAPCO,  which consent will not
       be  unreasonably  withheld;  provided  that a Borrower  may without such
       consent merge,  consolidate  with, or purchase  substantially all of the
       assets of, or sell  substantially  all of its  assets to, an  affiliated
       investment  company or series thereof,  as provided for in Rule 17a-8 of
       the Investment Company Act of 1940.

       15. EVENTS OF DEFAULT. If any of the following events (each an "Event of
Default")  shall  occur  (it being  understood  that an Event of  Default  with
respect to one Fund or Borrower  shall not  constitute an Event of Default with
respect to any other Fund or Borrower):

               (a) Any  Borrower  or  Fund  shall  default  in the  payment  of
       principal or interest on any Loan or any other fee due  hereunder  for a
       period of five (5) days after the same

       Facility Fee at a date fixed for the payment thereof;

               (b) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 13 hereof and such default
       shall not have been  remedied  within  thirty  (30) days  after  written
       notice thereof shall have been given such Borrower or Fund by CAPCO;

               (c) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 14 hereof;

               (d) Any  Borrower or Fund shall  default in the  performance  or
       compliance  with any other term contained  herein and such default shall
       not have been  remedied  within  thirty (30) days after  written  notice
       thereof shall have been given such Borrower or Fund by CAPCO;

               (e) Any  representation  or warranty  made by a Borrower or Fund
       herein or pursuant hereto shall prove to have been false or incorrect in
       any material respect when made;

               (f) An event of default shall occur and be continuing  under any
       other facility;  then, in any event, and at any time thereafter,  if any
       Event of Default shall be continuing, CAPCO may by written notice to the
       applicable  Borrower or Fund (i)  terminate the Facility with respect to
       such  Borrower or Fund and (ii)  declare the  principal  and interest in
       respect of any outstanding  Loans with respect to such Borrower or Fund,
       and all other  amounts due  hereunder  with respect to such  Borrower or
       Fund,  to be  immediately  due and payable  whereupon  the principal and
       interest in respect  thereof and all other amounts due  hereunder  shall
       become forthwith due and payable without presentment, demand, protest or
       other  notice of any  kind,  all of which  are  expressly  waived by the
       Borrowers.

       16.  NEW  BORROWERS;  NEW  FUNDS.  So long as no  Event  of  Default  or
condition  which,  with the  passage of time or the giving of notice,  or both,
would  constitute or become an Event of Default has occurred and is continuing,
and with the prior  consent of CAPCO,  which  consent will not be  unreasonably
withheld:

               (a) Any investment  company that becomes part of the same "group
       of  investment  companies"  (as that term is defined in Rule 11a-3 under
       the  Investment  Company Act of 1940) as the original  Borrowers to this
       Agreement,  may, by  submitting  an amended  Schedule A and Exhibit B to
       this  Agreement to CAPCO (which  amended  Schedule A and Exhibit B shall
       replace the corresponding Schedule and Exhibit which are, then a part of
       this  Agreement)  and  such  other  documents  as CAPCO  may  reasonably
       request,  become a party to this  Agreement  and may become a "Borrower"
       hereunder; and

<PAGE>

               (b) A Borrower  may,  by  submitting  an amended  Schedule A and
       Exhibit B to this  Agreement  to CAPCO  (which  amended  Schedule  A and
       Exhibit B shall replace the corresponding Schedule and Exhibit which are
       then a part of this  Agreement),  add additional Funds for whose benefit
       such Borrower may borrow Loans.  No such amendment of Schedule A to this
       Agreement shall amend the Borrowing Limit applicable to any Fund without
       the prior approval of CAPCO.

       17. LIMITED  RECOURSE.  CAPCO agrees (i) that any claim,  liability,  or
obligation  arising  hereunder  or under the Note  whether  on  account  of the
principal of any Loan,  interest thereon,  or any other amount due hereunder or
thereunder  shall be satisfied  only from the assets of the  specific  Fund for
whose  benefit a Loan is  borrowed  and in any event in an amount not to exceed
the outstanding  principal amount of any Loan borrowed for such Fund's benefit,
together  with  accrued and unpaid  interest  due and owing  thereon,  and such
Fund's  share  of any  other  amount  due  hereunder  and  under  the  Note (as
determined in accordance with the provisions hereof) and (ii) that no assets of
any fund shall be used to satisfy any claim,  liability,  or obligation arising
hereunder or under the Note with respect to the outstanding principal amount of
any Loan  borrowed  for the benefit of any other Fund or any accrued and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount
due  hereunder  and  under  the  Note (as  determined  in  accordance  with the
provisions hereof).

       18. REMEDIES ON DEFAULT. In case any one or more Events of Default shall
occur and be continuing, CAPCO may proceed to protect and enforce its rights by
an action at law, suit in equity or other appropriate proceedings,  against the
applicable  Borrower(s)  and/or  Fund(s),  as the case may be. In the case of a
default  in the  payment of any  principal  or  interest  on any Loan or in the
payment of any fee due hereunder,  the relevant  Fund(s) (to be allocated among
such Funds as the Borrowers deem  appropriate)  shall pay to CAPCO such further
amount as shall be  sufficient  to cover the cost and  expense  of  collection,
including, without limitation, reasonable attorney's fees and expenses.

       19. NO WAIVER OF  REMEDIES.  No course of dealing or failure or delay on
the part of CAPCO in exercising any right or remedy hereunder or under the Note
shall  constitute a waiver of any right or remedy  hereunder or under the Note,
nor shall any partial  exercise of any right or remedy  hereunder  or under the
Note preclude any further  exercise  thereof or the exercise of any other right
or remedy  hereunder  or under the Note.  Such  rights and  remedies  expressly
provided are cumulative and not exclusive of any rights or remedies which CAPCO
would otherwise have.

       20.  EXPENSES.  The  Fund(s)  (to be  allocated  among  the Funds as the
Borrowers deem  appropriate)  shall pay on demand all reasonable  out-of-pocket
costs and expenses (including reasonable attorney's fees and expenses) incurred
by  CAPCO  in  connection  with  the  collection  and  any  other   enforcement
proceedings of or regarding this Agreement, any Loan or the Note.

       21.  BENEFIT OF AGREEMENT.  This Agreement and the Note shall be binding
upon  and  inure  for  the  benefit  of and be  enforceable  by the  respective
successors  and assigns of the parties  hereto;  provided that no party to this
Agreement  or the Note may  assign any of its rights  hereunder  or  thereunder
without the prior written consent of the other parties.

<PAGE>

       22.  NOTICES.  All  notices  hereunder  and all  written,  facsimile  or
telecopied  confirmations  of Oral Requests made hereunder shall be sent to the
Borrowers as indicated on EXHIBIT B and to CAPCO as indicated on EXHIBIT C.

       23.  MODIFICATIONS.  No provision  of this  Agreement or the Note may be
waived,  modified  or  discharged  except by mutual  written  agreement  of all
parties. THIS WRITTEN LOAN AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT
BETWEEN  THE  PARTIES  AND  MAY  NOT BE  CONTRADICTED  BY  EVIDENCE  OF  PRIOR,
CONTEMPORANEOUS  OR SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  THERE ARE NO
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

       24. GOVERNING LAW AND JURISDICTION.  This Agreement shall be governed by
and construed in accordance  with the laws of the state of Texas without regard
to the choice of law provisions thereof.

       25. TRUST  DISCLAIMER.  Neither the  shareholders,  trustees,  officers,
employees and other agents of any Borrower or Fund shall be personally bound by
or liable for any indebtedness,  liability or obligation hereunder or under the
Note nor shall resort be had to their private  property for the satisfaction of
any obligation or claim hereunder.

copies hereof and return one to us,  whereupon this Agreement  shall be binding

       FOR VALUE  RECEIVED,  each of the  undersigned  (each a  "Borrower"  and
collectively the "Borrowers"),  severally and not jointly, on behalf of and for
the benefit of the series of funds  comprising  each such Borrower as listed on
Schedule A to the  Agreement as defined  below (each a "Fund" and  collectively
the "Funds") promises to pay to the order of USAA Capital Corporation ("CAPCO")
at CAPCO's  office  located at 9800  Fredericksburg  Road,  San Antonio,  Texas
78288,  in  lawful  money of the  United  States  of  America,  in  immediately
available  funds,  the  principal  amount  of all  Loans  made by CAPCO to such
Borrower for the benefit of the applicable  Funds under the Facility  Agreement
Letter dated January 12, 1999 (as amended or modified, the "Agreement"),  among
the  Borrowers and CAPCO,  together with interest  thereon at the rate or rates
set forth in the Agreement.  All payments of interest and principal outstanding
shall be made in accordance with the terms of the Agreement.

       This Note  evidences  Loans made  pursuant  to, and is  entitled  to the
benefits  of,  the  Agreement.  Terms not  defined in this Note shall be as set
forth in the Agreement.

       CAPCO is authorized to endorse the  particulars  of each Loan  evidenced
hereby  on  the  attached  Schedule  and  to  attach  additional  Schedules  as
necessary,  provided  that the failure of CAPCO to do so or to do so accurately
shall not affect the obligations of any Borrower (or the Fund for whose benefit
it is borrowing) hereunder.

       Each Borrower waives all claims to  presentment,  demand,  protest,  and
notice  of  dishonor.  Each  Borrower  agrees  to pay all  reasonable  costs of
collection,  including  reasonable  attorney's  fees  in  connection  with  the
enforcement of this Note.

       CAPCO hereby agrees (i) that any claim, liability, or obligation arising
hereunder  or under the  Agreement  whether on account of the  principal of any
Loan,  interest thereon,  or any other amount due hereunder or thereunder shall
be satisfied only from the assets of the specific Fund for whose benefit a Loan
is  borrowed  and in any  event in an  amount  not to  exceed  the  outstanding
principal  amount of any Loan borrowed for such Fund's  benefit,  together with
accrued and unpaid interest due and owing thereon, and such Fund's share of any
other amount due hereunder and under the Agreement (as determined in accordance
with the provisions of the Agreement) and (ii) that no assets of any Fund shall
be used to satisfy any claim,  liability,  or obligation  arising  hereunder or
under the Agreement  with respect to the  outstanding  principal  amount of any
Loan  borrowed  for the  benefit  of any other Fund or any  accrued  and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount
due hereunder

of any  Borrower  or Fund  shall  be  personally  bound  by or  liable  for any
indebtedness,  liability  or  obligation  hereunder or under the Note nor shall
resort be had to their private  property for the satisfaction of any obligation
or claim hereunder.

       Loans under the Agreement and this Note are  subordinated  to loans made
under the  $100,000,000  364-day  committed  Mater  Revolving  Credit  Facility
Agreement  between the Borrowers and  NationsBank,  N.A.  (NationsBank),  dated
January 13,  1999,  in the manner and to the extent set forth in the  Agreement
among the Borrowers, CAPCO and NationsBank, dated January 13, 1999.

         This Note shall be governed by the laws of the state of Texas.

January 13, 1999


USAA Mutual Fund, Inc.,
USAA Investment Trust,
USAA Tax Exempt Fund, Inc., and USAA State Tax-Free Trust, on behalf of and for
the benefit of the series of funds  comprising  each such Borrower as set forth
on Schedule A hereto 9800 Fredericksburg Road San Antonio, Texas 78288

Attention:  Michael J.C. Roth, President

Gentlemen:

This  Facility  Agreement  Letter (this  "Agreement")  sets forth the terms and
conditions  for  loans  (each a "Loan"  and  collectively  the  "Loans")  which
NationsBank,  N.A.,  successor by merger to  NationsBank  of Texas,  N.A.  (the
"Bank"),  agrees to make  during the period  commencing  January  13,  1999 and
ending January 12, 2000 (the "Facility Period") to USAA Mutual Fund, Inc., USAA
Investment  Trust,  USAA Tax Exempt Fund,  Inc., and USAA State Tax-Free Trust,
and each  investment  company  which may become a party hereto  pursuant to the
terms of this Agreement (each a "Borrower" and collectively  the  "Borrowers"),
each of which is executing  this  Agreement on behalf of and for the benefit of
the series of funds  comprising  each such  Borrower as set forth on Schedule A
hereto (as hereafter  modified or amended in accordance  with the terms hereof)
(each a "Fund" and collectively  the "Funds"),  under a master revolving credit
facility (the "Facility"). This Agreement replaces in its entirety that certain
Facility  Agreement  Letter dated January 14, 1998,  as  heretofore  amended or
modified, between the Borrowers and the Bank. The Bank and the Borrowers hereby
agree as follows:

       1. AMOUNT.  The aggregate  principal  amount of the Loans to be advanced
under this Facility shall not exceed, at any one time outstanding,  One Hundred
Million  United States  Dollars (U.S.  $100,000,000)  (the  "Commitment").  The
aggregate principal amount of the Loans which may be borrowed by a Borrower for
the benefit of a particular  Fund under the  Facility and the Other  Facilities
(hereinafter  defined) shall not exceed the percentage (the "Borrowing  Limit")
of the total assets of such Fund as set forth on Schedule A hereto.

       2. PURPOSE AND  LIMITATIONS  ON  BORROWINGS.  Each Borrower will use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the Fund for whose  benefit it is  borrowing  in  accordance  with such  Fund's
Borrowing  Limit and  prospectus in effect at the time of such Loan.  Portfolio
securities  may not be  purchased  by a Fund while there is a Loan  outstanding
under the Facility and/or a loan outstanding under the Other Facilities for the
benefit of such Fund, if the aggregate amount of such Loan and such other loans
exceed 5% of the total assets

<PAGE>

of such Fund. The Borrowers will not, and will not permit any Fund to, directly
or indirectly, use any proceeds of any Loan for any purpose which would violate
any provision of any  applicable  statute,  regulation,  order or  restriction,
including, without limitation,  Regulation U, Regulation T, Regulation X or any
other regulation of the Board of Governors of the Federal Reserve System or the
Securities  Exchange Act of 1934,  as amended.  If  requested by the Bank,  the
Borrowers  will promptly  furnish the Bank with a statement in conformity  with
the requirements of Federal Reserve Form U-1 as referred to in Regulation U.

       3.  BORROWING  RATE AND MATURITY OF LOANS.  The principal  amount of the
Loans  outstanding  from time to time shall bear  interest  at a rate per annum
equal to, at the option of the applicable Borrower(s), (i) the aggregate of the
Federal  Funds Rate (as defined  below) plus .28 of one percent  (1%) (28 basis
points) or (ii) the aggregate of the London Interbank  Offered Rate (as defined
below) plus 28 basis points.  The rate of interest  payable on such outstanding
amounts  shall  change on each date that the Federal  Funds Rate shall  change.
Interest  on the Loans shall be  calculated  on the basis of a year of 360 days
and the actual days elapsed but shall not exceed the highest lawful rate.  Each
Loan  will  be for an  established  number  of days  to be  agreed  upon by the
applicable Borrower(s) and the Bank and, in the absence of such agreement, will
mature on the earlier of three  months  after the date of such Loan or the last
day of the  Facility  Period.  The term  "Federal  Funds Rate," as used herein,
shall mean the overnight  rate for Federal funds  transactions  between  member
banks of the Federal Reserve  System,  as published by the Federal Reserve Bank
of New York or, if not so published, as determined in good faith by the Bank in
accordance with its customary practices; and the term "London Interbank Offered
Rate," as used  herein,  shall  mean the rate per annum  (rounded  upwards,  if
necessary,  to the nearest 1/100 of 1%) appearing on Telerate Page 3750 (or any
successor page) as the London Interbank offered rate for deposits in Dollars at
approximately  11:00 a.m.  London time two business days prior to the first day
of the interest period (of 7 or 14 days or one, two or three months as selected
by the  Borrower(s))  for which the London  Interbank  Offered Rate is to be in
effect,  as  adjusted  by the Bank in good  faith  and in  accordance  with its
customary  practices  for any reserve  costs  imposed on the Bank under Federal
Reserve Board  Regulation D with respect to  "Euro-currency  Liabilities".  The
London Interbank  Offered Rate shall not be available  hereunder if it would be
unlawful  for the Bank to make or maintain  Loans based on such rate or if such
rate does not, in the good faith judgment of the Bank,  fairly reflect the cost
to the Bank of making or maintaining  Loans. The London Interbank  Offered Rate
shall  not be  available  for any  interest  period  which,  if such  rate were
available,  would begin after the occurrence and during the  continuation of an
Event of Default (as defined  below).  Any past due  principal  and/or  accrued
interest  shall bear interest at a rate per annum equal to the aggregate of the
Federal Funds Rate plus 1.125 percent (112.5 basis points) and shall be payable
on demand.  If the applicable  Borrowers do not  affirmatively  elect to have a
Loan or Loans bear interest based on the London Interbank Offered Rate at least
two  business  days  prior  to the  first  day of a  possible  interest  period
applicable thereto, such Loan or Loans shall bear interest based on the Federal
Funds Rate until such election is affirmatively made.

       4. ADVANCES, PAYMENTS,  PREPAYMENTS AND READVANCES. Upon each Borrower's
request,  and subject to the terms and conditions  contained  herein,  the Bank
shall  make  Loans to each  Borrower  on behalf of and for the  benefit  of its
respective  Fund(s) during the Facility  Period,  and each Borrower may borrow,
repay and reborrow funds hereunder. The Loans shall be

<PAGE>

evidenced by a duly executed and delivered  Master Grid  Promissory Note in the
form of EXHIBIT A. Each Loan shall be in an aggregate  amount not less than One
Hundred  Thousand  United States Dollars (U.S.  $100,000) and increments of One
Thousand  United States  Dollars (U.S.  $1,000) in excess  thereof.  Payment of
principal  and  interest  due with respect to each Loan shall be payable at the
maturity of such Loan and shall be made in funds  immediately  available to the
Bank prior to 2 p.m. Dallas time on the day such payment is due, or as the Bank
shall  otherwise  direct  from  time to time  and,  subject  to the  terms  and
conditions  hereof,  may  be  repaid  with  the  proceeds  of a  new  borrowing
hereunder. Notwithstanding any provision of this Agreement to the contrary, all
Loans, accrued but unpaid interest and other amounts payable hereunder shall be
due and payable upon  termination of the Facility  (whether by  acceleration or
otherwise).  If any Loan bearing interest based on the London Interbank Offered
Rate is repaid or  prepaid  other  than on the last day of an  interest  period
applicable thereto, the Fund which is the beneficiary of such Loan shall pay to
the Bank promptly upon demand such amount as the Bank  determines in good faith
is necessary to compensate the Bank for any reasonable cost or expense incurred
by the Bank as a result of such repayment or prepayment in connection  with the
reemployment  of funds in an  amount  equal to such  repayment  or  prepayment.
Whenever  the Bank seeks to assess for any such cost or expense it will provide
a certificate as the Borrower(s) shall reasonably request.

       5. FACILITY  FEE.  Beginning  with the date of this  Agreement and until
such time as all Loans have been  irrevocably  repaid to the Bank in full,  and
the Bank is no longer obligated to make Loans, the Funds (to be allocated among
the Funds as the Borrowers deem  appropriate)  shall pay to the Bank a facility
fee (the  "Facility  Fee") in the amount of .07 of one percent (7 basis points)
of the amount of the  Commitment,  as it may be reduced  pursuant to section 6.
The Facility  Fee shall be payable  quarterly  in arrears  beginning  March 31,
1999,  and  upon  termination  of the  Facility  (whether  by  acceleration  or
otherwise).

       6. OPTIONAL TERMINATION OR REDUCTION OF COMMITMENT.  The Borrowers shall
have the right upon at least three (3) business  days prior  written  notice to
the Bank, to terminate or reduce the unused portion of the Commitment. Any such
reduction  of the  Commitment  shall be in the  amount of Five  Million  United
States Dollars (U.S. $5,000,000) or any larger integral multiple of One Million
United States  Dollars (U.S.  $1,000,000)  (except that any reduction may be in
the aggregate  amount of the unused  Commitment).  Accrued fees with respect to
the terminated Commitment shall be payable to the Bank on the effective date of
such termination.

       7.   MANDATORY   TERMINATION  OF   COMMITMENT.   The  Commitment   shall
automatically  terminate on the last day of the  Facility  Period and any Loans
then outstanding  (together with accrued interest thereon and any other amounts
owing hereunder) shall be due and payable on such date.

       8.  COMMITTED  FACILITY.  The Bank  acknowledges  that the Facility is a
committed  facility  and  that the Bank  shall  be  obligated  to make any Loan
requested during the Facility Period under this Agreement, subject to the terms
and conditions hereof; provided,  however, that the Bank shall not be obligated
to make any Loan if this Facility has been  terminated by the Borrowers,  or if
at the time of a request for a Loan by a Borrower (on behalf of the  applicable
Fund(s)) there exists any Event of Default or condition which, with the passage
of time or giving of notice, or both, would

<PAGE>

constitute or become an Event of Default with respect to such Borrower (or such
applicable Fund(s)).

       9. LOAN  REQUESTS.  Each request for a Loan (each a "Borrowing  Notice")
shall be in writing by the applicable Borrower(s), except that such Borrower(s)
may make an oral  request  (each an "Oral  Request")  provided  that  each Oral
Request  shall be followed by a written  Borrowing  Notice  within one business
day. Each Borrowing  Notice shall specify the following  terms ("Terms") of the
requested  Loan:  (i) the date on which such Loan is to be disbursed,  (ii) the
principal amount of such Loan,  (iii) the Borrower(s)  which are borrowing such
Loan and the  amount of such Loan to be  borrowed  by each  Borrower,  (iv) the
Funds for whose  benefit the Loan is being  borrowed and the amount of the Loan
which is for the benefit of each such Fund,  (v)  whether  such Loan shall bear
interest at the Federal Funds Rate or the London  Interbank  Offered Rate,  and
(vi) the requested  maturity date of the Loan. Each Borrowing Notice shall also
set forth the total assets of each Fund for whose benefit a portion of the Loan
is being borrowed as of the close of business on the day immediately  preceding
the date of such Borrowing Notice.  Borrowing Notices shall be delivered to the
Bank by 1:00 p.m.  Dallas time on the day the Loan is  requested  to be made if
such Loan is to bear interest  based on the Federal Funds Rate or by 10:00 a.m.
Dallas time on the second  business day before the Loan is requested to be made
if such Loan is to bear interest based on the London Interbank Offered Rate.

Each  Borrowing  Notice shall  constitute a  representation  to the Bank by the
applicable  Borrower(s)  that  all of the  representations  and  warranties  in
Section  12 hereof  are true and  correct  as of such date and that no Event of
Default or other  condition which with the passage of time or giving of notice,
or both, would result in an Event of Default, has occurred or is occurring.

       10.  CONFIRMATIONS;  CREDITING  OF FUNDS;  RELIANCE  BY THE  BANK.  Upon
receipt by the Bank of a Borrowing Notice:

               (a)  The  Bank  shall  send  each  applicable  Borrower  written
       confirmation  of the Terms of such Loan via  facsimile or  telecopy,  as
       soon as reasonably practicable;  provided,  however, that the failure to
       do so shall not affect the obligation of any such Borrower;

               (b) The Bank shall make such Loan in  accordance  with the Terms
       by transfer of the Loan amount in immediately  available  funds,  to the
       account of the applicable  Borrower(s) as specified in EXHIBIT B to this
       Agreement or as such Borrower(s)  shall otherwise specify to the Bank in
       a writing signed by an Authorized  Individual (as defined in Section 11)
       of such Borrower(s) and sent to the Bank via facsimile or telecopy; and

               (c) The Bank shall make  appropriate  entries on the Note or the
       records of the Bank to reflect the Terms of the Loan; provided, however,
       that the  failure  to do so  shall  not  affect  the  obligation  of any
       Borrower.

The Bank shall be entitled to rely upon and act hereunder  pursuant to any Oral
Request  which it  reasonably  believes  to have  been  made by the  applicable
Borrower through an Authorized  Individual.  If any Borrower  believes that the
confirmation relating to any Loan contains any error

<PAGE>

or discrepancy  from the applicable  Oral Request,  such Borrower will promptly
notify the Bank thereof.

       11.  BORROWING  RESOLUTIONS  AND OFFICERS'  CERTIFICATES;  SUBORDINATION
AGREEMENT.  Prior to the making of any Loan  pursuant  to this  Agreement,  the
Borrowers  shall have  delivered to the Bank (a) the duly  executed  Note,  (b)
resolutions of each Borrower's Trustees or Board of Directors  authorizing such
Borrower to execute,  deliver and perform this Agreement and the Note on behalf
of the applicable Funds, (c) an Officer's Certificate in substantially the form
set  forth in  EXHIBIT D to this  Agreement,  authorizing  certain  individuals
("Authorized  Individuals"),  to take on behalf of each  Borrower (on behalf of
the applicable Funds) actions  contemplated by this Agreement and the Note, (d)
a subordination  agreement in substantially  the form set forth in EXHIBIT E to
this Agreement,  and (e) the opinion of counsel to USAA  Investment  Management
Company, manager and advisor to the Borrowers,  with respect to such matters as
the Bank may reasonably request.

       12. REPRESENTATIONS AND WARRANTIES. In order to induce the Bank to enter
into this Agreement and to make the Loans provided for hereunder, each Borrower
hereby  makes with  respect to itself,  and as may be  relevant,  the series of
Funds  comprising such Borrower the following  representations  and warranties,
which shall survive the execution and delivery hereof and of the Note:

               (a) ORGANIZATION;  STANDING,  ETC. The Borrower is a corporation
       or trust duly organized,  validly  existing,  and in good standing under
       applicable state laws and has all requisite corporate or trust power and
       authority to carry on its  respective  businesses  as now  conducted and
       proposed to be  conducted,  to enter into this  Agreement  and all other
       documents  to be  executed  by it in  connection  with the  transactions
       contemplated hereby, to issue and borrow under the Note and to carry out
       the terms hereof and thereof;

               (b)  FINANCIAL  INFORMATION;  DISCLOSURE,  ETC. The Borrower has
       furnished  the Bank with certain  financial  statements of such Borrower
       with  respect  to itself  and the  applicable  Funds,  all of which such
       financial  statements  have been prepared in accordance  with  generally
       accepted accounting  principles applied on a consistent basis and fairly
       present  the  financial  position  and  results  of  operations  of such
       Borrower  and the  applicable  Funds on the  dates  and for the  periods
       indicated. Neither this Agreement nor any financial statements,  reports
       or  other  documents  or  certificates  furnished  to the  Bank  by such
       Borrower or the  applicable  Funds in connection  with the  transactions
       contemplated  hereby contain any untrue  statement of a material fact or
       omit to  state  any  material  fact  necessary  to make  the  statements
       contained herein or therein in light of the circumstances  when made not
       misleading;

               (c)  AUTHORIZATION;   COMPLIANCE  WITH  OTHER  INSTRUMENTS.  The
       execution,  delivery and performance of this Agreement and the Note, and
       borrowings  hereunder,  have  been  duly  authorized  by  all  necessary
       corporate  or trust  action of the  Borrower  and will not result in any
       violation of or be in conflict  with or  constitute a default  under any
       term of the charter,  by-laws or trust agreement of such Borrower or the
       applicable  Funds,  or of any  borrowing  restrictions  or prospectus or
       statement of additional information of such Borrower

<PAGE>

       or the  applicable  Funds,  or of any agreement,  instrument,  judgment,
       decree, order,  statute,  rule or governmental  regulation applicable to
       such Borrower,  or result in the creation of any mortgage,  lien, charge
       or encumbrance  upon any of the properties or assets of such Borrower or
       the  applicable  Funds  pursuant to any such term.  The Borrower and the
       applicable  Funds are not in violation  of any term of their  respective
       charter,   by-laws  or  trust  agreement,  and  such  Borrower  and  the
       applicable  Funds  are  not in  violation  of any  material  term of any
       agreement  or  instrument  to which they are a party,  or to the best of
       such Borrower's knowledge, of any judgment, decree, order, statute, rule
       or governmental regulation applicable to them;

               (d) SEC COMPLIANCE. The Borrower and the applicable Funds are in
       compliance  in  all  material   respects  with  all  federal  and  state
       securities  or similar  laws and  regulations,  including  all  material
       rules,  regulations  and  administrative  orders of the  Securities  and
       Exchange Commission (the "SEC") and applicable Blue Sky authorities. The
       Borrower  and the  applicable  Funds are in  compliance  in all material
       respects  with all of the  provisions of the  Investment  Company Act of
       1940,  and such  Borrower  has filed all  reports  with the SEC that are
       required of it or the applicable Funds;

               (e) LITIGATION.  There is no action,  suit or proceeding pending
       or, to the best of the  Borrower's  knowledge,  threatened  against such
       Borrower or the  applicable  Funds in any court or before any arbitrator
       or  governmental  body which seeks to restrain  any of the  transactions
       contemplated by this Agreement or which, if adversely determined,  could
       have a material  adverse effect on the assets or business  operations of
       such  Borrower or the  applicable  Funds or the ability of such Borrower
       and the applicable Funds to pay and perform their obligations  hereunder
       and under the Notes;

               (f) BORROWERS'  RELATIONSHIP  TO FUNDS.  The assets of each Fund
       for whose  benefit  Loans are  borrowed by the  applicable  Borrower are
       subject to and liable for such Loans and are available to the applicable
       Borrower for the repayment of such Loans; and

               (g) YEAR 2000  PREPAREDNESS.  The Borrower  has (i)  initiated a
       review and  assessment  of all areas within its business and  operations
       (including  those  affected by suppliers,  vendors and  customers)  that
       could be  adversely  affected by the "Year 2000  Problem"  (that is, the
       risk that computer  applications  used by such Borrower may be unable to
       recognize  and  perform  properly  date-sensitive   functions  involving
       certain  dates  prior to and any date after  December  31,  1999),  (ii)
       developed a plan and timeline for  addressing the Year 2000 Problem on a
       timely  basis,  and (iii) to date,  implemented  that plan in accordance
       with that timetable.  Based on the foregoing,  such Borrower  reasonably
       believes  that  all  computer  applications  that  are  material  to its
       business and operations are reasonably  expected on a timely basis to be
       able to perform properly  date-sensitive  functions for all dates before
       and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
       the extent that a failure to do so could not  reasonably  be expected to
       have a material  adverse effect on the assets or business  operations of
       such  Borrower or the  applicable  Funds or the ability of such Borrower
       and the applicable Funds to pay and perform their obligations  hereunder
       and under the Note.

       13.  AFFIRMATIVE  COVENANTS  OF THE  BORROWERS.  Until  such time as all
amounts of principal and interest due to the Bank by a Borrower pursuant to any
Loan made to such Borrower is  irrevocably  paid in full, and until the Bank is
no longer  obligated to make Loans to such Borrower,  such Borrower (for itself
and on behalf of its respective Funds) agrees:

               (a) To deliver to the Bank as soon as possible  and in any event
       within  ninety  (90)  days  after  the end of each  fiscal  year of such
       Borrower and the applicable Funds, Statements of Assets and Liabilities,
       Statements of Operations and Statements of Changes in Net Assets of each
       applicable  Fund for such fiscal year,  as set forth in each  applicable
       Fund's Annual Report to shareholders  together with a calculation of the
       maximum  amount  which  each  applicable  Fund  could  borrow  under its
       Borrowing Limit as of the end of such fiscal year;

               (b) To deliver to the Bank as soon as available and in any event
       within seventy-five (75) days after the end of each semiannual period of
       such  Borrower  and the  applicable  Funds,  Statements  of  Assets  and
       Liabilities,  Statements of Operations  and Statements of Changes in Net
       Assets of each applicable Fund as of the end of such semiannual  period,
       as  set  forth  in  each   applicable   Fund's   Semiannual   Report  to
       shareholders,  together with a calculation  of the maximum  amount which
       each  applicable  Fund could borrow under its Borrowing Limit at the end
       of such semiannual period;

               (c) To deliver to the Bank prompt  notice of the  occurrence  of
       any event or condition which  constitutes,  or is likely to result in, a
       change in such Borrower or any applicable Fund which could reasonably be
       expected to materially  adversely  affect the ability of any  applicable
       Fund to  promptly  repay  outstanding  Loans made for its benefit or the
       ability of such Borrower to perform its obligations under this Agreement
       or the Note;

               (d) To do, or cause to be done, all things necessary to preserve
       and keep in full force and effect the  corporate  or trust  existence of
       such Borrower and all permits,  rights and privileges  necessary for the
       conduct of its  businesses  and to comply in all material  respects with
       all  applicable  laws,   regulations  and  orders,   including   without
       limitation, all rules and regulations promulgated by the SEC;

               (e) To promptly  notify the Bank of any  litigation,  threatened
       legal  proceeding or  investigation  by a governmental  authority  which
       could  materially  affect the ability of such Borrower or the applicable
       Funds to promptly repay the outstanding Loans or otherwise perform their
       obligations hereunder;

               (f) In the event a Loan for the benefit of a particular  Fund is
       not  repaid in full  within 10 days after the date it is  borrowed,  and
       until such Loan is repaid in full,  to  deliver to the Bank,  within two
       business  days  after  each  Friday  occurring  after  such 10th day,  a
       statement setting forth the total assets of such Fund as of the close of
       business on each such Friday; and

               (g) Upon the request of the Bank,  which may be made by the Bank
       from  time to time in the  event the Bank in good  faith  believes  that
       there has been a material adverse

<PAGE>

       change in the capital markets generally,  to deliver to the Bank, within
       two business  days after such  request,  a statement  setting  forth the
       total assets of each Fund for whose benefit a Loan is outstanding on the
       date of such request.

       14. NEGATIVE COVENANTS OF THE BORROWERS.  Until such time as all amounts
of principal  and  interest due to the Bank by a Borrower  pursuant to any Loan
made to such  Borrower is  irrevocably  paid in full,  and until the Bank is no
longer obligated to make Loans to such Borrower,  such Borrower (for itself and
on behalf of its respective Funds) agrees:

               (a) Not to incur any indebtedness for borrowed money (other than
       pursuant  to  a  Five  Hundred   Million   United  States  Dollar  (U.S.
       $500,000,000)  uncommitted  master  revolving  credit facility and a Two
       Hundred Fifty Million United States Dollar (U.S. $250,000,000) Committed
       Master  Revolving  Credit  Facility with USAA Capital  Corporation  (the
       "Other  Facilities")  and  overdrafts  incurred at the  custodian of the
       Funds from time to time in the ordinary  course of business)  except the
       Loans, without the prior written consent of the Bank, which consent will
       not be unreasonably withheld; and

               (b) Not to  dissolve or  terminate  its  existence,  or merge or
       consolidate   with  any  other   person  or  entity,   or  sell  all  or
       substantially  all of its  assets in a single  transaction  or series of
       related  transactions  (other than assets  consisting of margin  stock),
       each without the prior written  consent of the Bank,  which consent will
       not be unreasonably withheld;  provided that a Borrower may without such
       consent merge,  consolidate  with, or purchase  substantially all of the
       assets of, or sell  substantially  all of its  assets to, an  affiliated
       investment  company or series thereof,  as provided for in Rule 17a-8 of
       the Investment Company Act of 1940.

       15. EVENTS OF DEFAULT. If any of the following events (each an "Event of
Default")  shall  occur  (it being  understood  that an Event of  Default  with
respect to one Fund or Borrower  shall not  constitute an Event of Default with
respect to any other Fund or Borrower):

               (a) Any  Borrower  or  Fund  shall  default  in the  payment  of
       principal or interest on any Loan or any other fee due  hereunder  for a
       period of five (5) days after the same becomes due and payable,  whether
       at maturity or with  respect to the Facility Fee at a date fixed for the
       payment thereof;

               (b) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 13 hereof and such default
       shall not have been  remedied  within  thirty  (30) days  after  written
       notice thereof shall have been given such Borrower or Fund by the Bank;

               (c) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 14 hereof;

               (d) Any  Borrower or Fund shall  default in the  performance  or
       compliance  with any other term contained  herein and such default shall
       not have been  remedied  within  thirty (30) days after  written  notice
       thereof shall have been given such Borrower or Fund by the Bank;

<PAGE>

               (e) Any  representation  or warranty  made by a Borrower or Fund
       herein or pursuant hereto shall prove to have been false or incorrect in
       any material respect when made;

               (f) USAA Investment  Management Company or any successor manager
       or investment  adviser,  provided that such  successor is a wholly-owned
       subsidiary  of USAA Capital  Corporation,  shall cease to be the Manager
       and investment advisor of each Fund; or

               (g) An event of default shall occur and be continuing  under the
       Other Facilities; then, in any event, and at any time thereafter, if any
       Event of Default shall be continuing,  the Bank may by written notice to
       the applicable Borrower or Fund (i) terminate its commitment to make any
       Loan  hereunder,  whereupon said commitment  shall  forthwith  terminate
       without any other  notice of any kind with  respect to such  Borrower or
       Fund and (ii)  declare  the  principal  and  interest  in respect of any
       outstanding  Loans with respect to such Borrower or Fund,  and all other
       amounts due  hereunder  with  respect to such  Borrower  or Fund,  to be
       immediately  due and payable  whereupon  the  principal  and interest in
       respect  thereof  and all  other  amounts  due  hereunder  shall  become
       forthwith due and payable without presentment,  demand, protest or other
       notice of any kind, all of which are expressly waived by the Borrowers.

       16.  NEW  BORROWERS;  NEW  FUNDS.  So long as no  Event  of  Default  or
condition  which,  with the  passage of time or the giving of notice,  or both,
would  constitute or become an Event of Default has occurred and is continuing,
and with the prior consent of the Bank,  which consent will not be unreasonably
withheld:

                (a) Any investment company that becomes part of the same "group
       of  investment  companies"  (as that term is defined in Rule 11a-3 under
       the  Investment  Company Act of 1940) as the original  Borrowers to this
       Agreement,  may, by  submitting  an amended  Schedule A and Exhibit B to
       this Agreement to the Bank (which amended Schedule A and Exhibit B shall
       replace  the  Schedule  A and  Exhibit  B which  are then a part of this
       Agreement) and such other documents as the Bank may reasonably  request,
       become a party to this Agreement and may become a "Borrower"  hereunder;
       and

                (b) A Borrower  may, by  submitting  an amended  Schedule A and
       Exhibit B to this  Agreement to the Bank (which  amended  Schedule A and
       Exhibit B shall  replace  the  Schedule A and Exhibit B which are then a
       part of this  Agreement),  add  additional  Funds for whose benefit such
       Borrower  may borrow  Loans.  No such  amendment  of  Schedule A to this
       Agreement shall amend the Borrowing Limit applicable to any Fund without
       the prior consent of the Bank.

       17. LIMITED RECOURSE. The Bank agrees (i) that any claim,  liability, or
obligation  arising  hereunder  or under the Note  whether  on  account  of the
principal of any Loan,  interest thereon,  or any other amount due hereunder or
thereunder  shall be satisfied  only from the assets of the  specific  Fund for
whose  benefit a Loan is  borrowed  and in any event in an amount not to exceed
the outstanding  principal amount of any Loan borrowed for such Fund's benefit,
together  with  accrued and unpaid  interest  due and owing  thereon,  and such
Fund's  share  of any  other  amount  due  hereunder  and  under  the  Note (as
determined in accordance with the provisions hereof) and (ii) that

<PAGE>

no  assets  of any Fund  shall be used to  satisfy  any  claim,  liability,  or
obligation  arising hereunder or under the Note with respect to the outstanding
principal  amount of any Loan borrowed for the benefit of any other Fund or any
accrued and unpaid interest due and owing thereon or such other Fund's share of
any other amount due hereunder and under the Note (as  determined in accordance
with the provisions hereof).

       18. REMEDIES ON DEFAULT. In case any one or more Events of Default shall
occur and be continuing, the Bank may proceed to protect and enforce its rights
by an action at law, suit in equity or other appropriate  proceedings,  against
the applicable Borrower(s) and/or Fund(s), as the case may be. In the case of a
default  in the  payment of any  principal  or  interest  on any Loan or in the
payment of any fee due hereunder,  the relevant  Fund(s) (to be allocated among
such  Funds as the  Borrowers  deem  appropriate)  shall  pay to the Bank  such
further  amount  as  shall be  sufficient  to cover  the  cost and  expense  of
collection,  including,  without  limitation,  reasonable  attorney's  fees and
expenses.

       19. NO WAIVER OF  REMEDIES.  No course of dealing or failure or delay on
the part of the Bank in exercising  any right or remedy  hereunder or under the
Note shall  constitute  a waiver of any right or remedy  hereunder or under the
Note, nor shall any partial  exercise of any right or remedy hereunder or under
the Note  preclude  any further  exercise  thereof or the exercise of any other
right or remedy hereunder or under the Note. Such rights and remedies expressly
provided are  cumulative  and not exclusive of any rights or remedies which the
Bank would otherwise have.

       20.  EXPENSES.  The  Fund(s)  (to be  allocated  among  the Funds as the
Borrowers deem  appropriate)  shall pay on demand all reasonable  out-of-pocket
costs and expenses (including reasonable attorney's fees and expenses) incurred
by the  Bank in  connection  with  the  collection  and any  other  enforcement
proceedings of or regarding this Agreement, any Loan or the Note.

       21.  BENEFIT OF AGREEMENT.  This Agreement and the Note shall be binding
upon  and  inure  for  the  benefit  of and be  enforceable  by the  respective
successors  and assigns of the parties  hereto;  provided that no party to this
Agreement  or the Note may  assign any of its rights  hereunder  or  thereunder
without the prior written  consent of the other parties.  The Bank may not sell
participations  and  subparticipations  in all or any  part of the  Loans  made
hereunder  without the prior consent of the Borrowers,  which consent shall not
be unreasonably withheld.

       22.  NOTICES.  All notices  hereunder  and all  written,  facsimiled  or
telecopied  confirmations  of Oral Requests made hereunder shall be sent to the
Borrowers  as indicated on EXHIBIT B and to the Bank as indicated on EXHIBIT C.
Written  communications  shall be deemed  to have  been duly  given and made as
follows: If sent by mail, seventy-two (72) hours after deposit in the mail with
first-class postage prepaid, addressed as provided in EXHIBIT B (the Borrowers)
and EXHIBIT C (the Bank);  and in the case of facsimile  or telecopy,  when the
facsimile or telecopy is received if on a business day or otherwise on the next
business day.

       23.  MODIFICATIONS.  No provision  of this  Agreement or the Note may be
waived,  modified  or  discharged  except by mutual  written  agreement  of all
parties. THIS WRITTEN LOAN AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT
BETWEEN THE

<PAGE>

PARTIES AND MAY NOT BE  CONTRADICTED BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS  OR
SUBSEQUENT  ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN  AGREEMENTS
BETWEEN THE PARTIES.

       24.  INCREASED  COST AND REDUCED  RETURN.  If at any time after the date
hereof,  the Bank (which  shall  include,  for  purposes of this  Section,  any
corporation  controlling the Bank) determines that the adoption or modification
of any applicable law regarding the Bank's required  levels of reserves,  other
than the reserve  requirement  taken into  account  when  computing  the London
Interbank  Offered  Rate as  provided in Section 3, or capital  (including  any
allocation of capital requirements or conditions), or similar requirements,  or
any  interpretation  or  administration  thereof  by  a  governmental  body  or
compliance  by the Bank with any of such  requirements,  has or would  have the
effect of (a)  increasing  the  Bank's  costs  relating  to the  Loans,  or (b)
reducing the yield or rate of return of the Bank on the Loans, to a level below
that which the Bank could have achieved but for the adoption or modification of
any such  requirements,  the  Funds  (to be  allocated  among  the Funds as the
Borrowers deem appropriate)  shall,  within fifteen (15) days of any request by
the Bank,  pay to the Bank  such  additional  amounts  as (in the  Bank's  sole
judgment, after good faith and reasonable computation) will compensate the Bank
for such increase in costs or reduction in yield or rate of return of the Bank.
Whenever  the  Bank  shall  seek  compensation  for any  increase  in  costs or
reduction in yield or rate of return,  the Bank shall provide a certificate  as
the Borrower(s) shall reasonably request. Failure by the Bank to demand payment
within 90 days of any additional  amounts payable  hereunder shall constitute a
waiver of the Bank's right to demand  payment of such amounts at any subsequent
time.  Nothing herein  contained shall be construed or so operate as to require
the Borrowers or the Funds to pay any interest,  fees, costs or charges greater
than is permitted by applicable law.

       25. GOVERNING LAW AND JURISDICTION.  This Agreement shall be governed by
and construed in accordance  with the laws of the state of Texas without regard
to the choice of law provisions thereof.

       26. TRUST  DISCLAIMER.  Neither the  shareholders,  trustees,  officers,
employees and other agents of any Borrower or Fund shall be personally bound by
or liable for any indebtedness,  liability or obligation hereunder or under the
Note nor shall resort be had to their private  property for the satisfaction of
any  obligation  or claim  hereunder.  If this letter  correctly  reflects your
agreement  with us,  please  execute  both copies  hereof and return one to us,
whereupon this Agreement shall be binding upon the Borrowers, the Funds and the
Bank.

Sincerely,

NATIONSBANK, N.A.

(LENDER)                            (DEBTOR)                   (CREDITOR)
- -------------------------------------------------------------------------------

1.   BACKGROUND.  Debtor is  or  may  be  indebted  to Lender  pursuant to that
     certain  Facility  Agreement  Letter dated January 13, 1999 between Debtor
     and  Lender  ("Senior  Facility  Agreement").  Debtor  also  is or  may be
     indebted to Creditor pursuant to certain Facility  Agreement Letters dated
     January 12,  1999  between  Debtor and  Creditor  ("Subordinated  Facility
     Agreements").  All debt (as hereinafter defined) under the Senior Facility
     Agreement  is  hereinafter  referred to as "senior  debt" and all debt (as
     hereinafter  defined)  under  the  Subordinated   Facility  Agreements  is
     hereinafter referred to as "subordinated debt".

2.   DEFINITION OF DEBT. The term "debt" as  used  in  the  terms "senior debt"
     and "subordinated debt" means all debts, obligations and liabilities,  now
     or hereafter existing, direct or indirect,  absolute or contingent,  joint
     or several, secured or unsecured, due or not due, contractual or tortious,
     liquidated  or  unliquidated,  arising by operation  of law or  otherwise,
     irrespective  of the person in whose favor such debt may  originally  have
     been created and  regardless  of the manner in which such debt has been or
     may  hereafter be acquired by Lender or Creditor,  as the case may be, and
     includes all costs  incurred to obtain,  preserve,  perfect or enforce any
     security  interest,  lien  or  mortgage,  or to  collect  any  debt  or to
     maintain,  preserve,  collect and enforce any collateral,  and interest on
     such amounts.

3.   SUBORDINATION OF DEBT.  Until  senior debt has  been paid  in full, Debtor
     will not pay and Creditor will not accept any payment on subordinated debt
     at any time that an Event of Default  (as  defined in the Senior  Facility
     Agreement)  has  occurred  and is  continuing  in respect of senior  debt.
     Anything of value received by Creditor on account of subordinated  debt in
     violation  of  this  agreement  will  be held by  Creditor  in  trust  and
     immediately  will be  turned  over to Lender  in the form  received  to be
     applied by Lender on senior debt.

4.   REMEDIES  OF  CREDITOR.  Until  all  senior  debt has  been  paid in full,
     without Lender's permission, Creditor will not be a party to any action or
     proceeding  against any person to recover  subordinated debt. Upon written
     request of Lender,  Creditor will file any claim or proof of claim or take
     any  other  action  to  collect   subordinated  debt  in  any  bankruptcy,
     receivership,  liquidation,  reorganization or other proceeding for relief
     of debtors or in connection with Debtor's insolvency, or in liquidation or
     marshaling  of  Debtor's  assets  or   liabilities,   or  in  any  probate
     proceeding,  and if any distribution  shall be made to Creditor,  Creditor
     will hold the same in trust for Lender and immediately  pay to Lender,  in
     the form received to be applied on senior debt,  all money or other assets
     received in any such  proceedings  on account of  subordinated  debt until
     senior debt shall have been paid in full.  If Creditor  shall fail to take
     any such  action  when  requested  by  Lender,  Lender  may  enforce  this
     agreement or as attorney in fact for Creditor and Debtor may take any such
     action on Creditor's behalf.  Creditor hereby irrevocably  appoints Lender
     Creditor's  attorney in fact to take any such  action  that  Lender  might
     request Creditor to take hereunder,  and to sue for,  compromise,  collect
     and receive all such money and other  assets and take any other  action in
     Lender's  own  name or in  Creditor's  name  that  Lender  shall  consider
     advisable for  enforcement  and  collection of  subordinated  debt, and to
     apply any amounts received on senior debt.

<PAGE>

5.   MODIFICATIONS.  At  any time and from  time  to  time,  without Creditor's
     consent or notice to  Creditor  and  without  liability  to  Creditor  and
     without  releasing or impairing any of Lender's rights against Creditor or
     any of Creditor's  obligations  hereunder,  Lender may take  additional or
     other security for senior debt;  release,  exchange,  subordinated or lose
     any security for senior debt; release any person obligated on senior debt,
     modify,  amend or waive  compliance with any agreement  relating to senior
     debt;  grant any  adjustment,  indulgence or forbearance to, or compromise
     with, any person liable for senior debt;  neglect,  delay,  omit,  fail or
     refuse to take or prosecute  any action for  collection of any senior debt
     or to foreclose upon any collateral or take or prosecute any action on any
     agreement securing any senior debt.

6.   SUBORDINATION OF LIENS. Creditor  subordinates  and makes  inferior to any
     security  interests,  liens or mortgages now or hereafter  securing senior
     debt all security interests, liens, or mortgages now or hereafter securing
     subordinated  debt. Any foreclosure  against any property  securing senior
     debt shall  foreclose,  extinguish  and discharge all security  interests,
     liens and mortgages  securing  subordinated debt, and any purchaser at any
     such foreclosure sale shall take title to the property so sold free of all
     security interest, liens and mortgages securing subordinated debt.

7.   STATEMENT  OF  SUBORDINATION;   ASSIGNMENT   BY   CREDITOR;    ADDITIONAL
     INSTRUMENTS.  Debtor and Creditor will cause any instrument  evidencing or
     securing  subordinated  debt to bear upon its face a  statement  that such
     instrument  is  subordinated  to senior debt as set forth  herein and will
     take all actions and execute all documents  appropriate  to carry out this
     agreement.  Creditor  will notify  Lender not less than 10 days before any
     assignment of any subordinated debt.

8.   ASSIGNMENT BY LENDER. Lender's rights under this agreement may be assigned
     in connection with any assignment or transfer of any senior debt.

9.   VENUE. Debtor and Creditor agree that this agreement is performable in the
     county of Lender's address set out above.

10.  CUMULATIVE RIGHTS; WAIVERS.  This instrument  is  cumulative  of all other
     rights  and  securities  of the  Lender.  No waiver by Lender of any right
     hereunder,  with respect to a particular  payment,  shall affect or impair
     its rights in any matters thereafter occurring.

11.  SUCCESSORS  AND  ASSIGNS.  This  instrument  is  binding  upon  and  shall
     inure to the benefit of the heirs, executors,  administrators,  successors
     and assigns of each of the parties hereto,  but Creditor covenants that it
     will not assign subordinated debt, or any part thereof, without making the
     rights and interests of the assignee  subject in all respects to the terms
     of this instrument.

12.  TERMINATION.  This agreement  shall terminate upon the termination of the
     Senior Facility Agreement and repayment in full of the senior debt.

Attention: Michael J.C. Roth, President

Gentlemen:

This  Facility  Agreement  Letter (this  "Agreement")  sets forth the terms and
conditions  for loans (each a "Loan" and  collectively  the "Loans") which USAA
Capital  Corporation  ("CAPCO")  may from time to time make  during  the period
commencing January 12, 1999 and ending January 11, 2000 (the "Facility Period")
to USAA Mutual Fund, Inc., USAA Investment  Trust,  USAA Tax Exempt Fund, Inc.,
and USAA State Tax-Free Trust,  and each investment  company which may become a
party hereto  pursuant to the terms of this  Agreement  (each a "Borrower"  and
collectively  the  "Borrowers"),  each of which is executing  this Agreement on
behalf  of and for the  benefit  of the  series of funds  comprising  each such
Borrower as set forth on Schedule A hereto (as hereafter modified or amended in
accordance with the terms hereof) (each a "Fund" and collectively the "Funds"),
under a master  revolving  credit  facility (the  "Facility").  USAA Investment
Management  Company is the Manager and Investment  Advisor of each Fund.  CAPCO
and the Borrowers hereby agree as follows:

       1.  AMOUNT.  The  aggregate  principal  amount of the Loans which may be
advanced under this Facility shall not exceed, at any one time outstanding, Two
Hundred Fifty Million Dollars ($250,000,000). The aggregate principal amount of
the Loans which may be borrowed by a Borrower  for the benefit of a  particular
Fund under this Facility shall not exceed the borrowing  limit (the  "Borrowing
Limit")  on  borrowings  applicable  to such Fund,  as set forth on  Schedule A
hereto.

       2. PURPOSE AND  LIMITATIONS  ON  BORROWINGS.  Each Borrower will use the
proceeds of each Loan made to it solely for temporary or emergency  purposes of
the Fund for whose  benefit it is  borrowing  in  accordance  with such  Fund's
Borrowing Limit (Schedule A) and prospectus in effect at the time of such Loan.
Portfolio  securities  may not be  purchased  by a Fund  while  there is a Loan
outstanding  under the Facility or any other facility,  if the aggregate amount
of such Loan and any other  such loan  exceeds  5% of the total  assets of such
Fund.

<PAGE>

       3.  BORROWING  RATE AND  MATURITY  OF LOANS.  CAPCO may make  Loans to a
Borrower and the principal  amount of the Loans  outstanding  from time to time
shall  bear  interest  at a rate per  annum  equal  to the rate at which  CAPCO
obtains  funding  in the  capital  markets.  Interest  on the  Loans  shall  be
calculated  on the basis of a year of 360 days and the actual days  elapsed but
shall not exceed the highest lawful rate.  Each loan will be for an established
number  of  days   agreed   upon  by  the   applicable   Borrower   and  CAPCO.
Notwithstanding the above, all Loans to a Borrower shall be made available at a
rate per annum equal to the rate at which CAPCO would make loans to  affiliates
and  subsidiaries.  Further,  if the  CAPCO  rate  exceeds  the rate at which a
Borrower could obtain funds pursuant to the NationsBank,  N.A.  ("NationsBank")
364-day committed  $100,000,000 Master Revolving Credit Facility,  the Borrower
will in the absence of predominating  circumstances,  borrow from  NationsBank.
Any past due principal  and/or  accrued  interest shall bear interest at a rate
per annum equal to the  aggregate of the Federal Funds Rate plus 1 percent (100
basis points) and shall be payable on demand.

       4. ADVANCES, PAYMENTS,  PREPAYMENTS AND READVANCES. Upon each Borrower's
request,  and subject to the terms and conditions contained herein, CAPCO shall
make Loans to each Borrower on behalf of and for the benefit of its  respective
Fund(s) during the Facility  Period,  and each Borrower may at CAPCO's sole and
absolute  discretion,  borrow,  repay and reborrow funds  hereunder.  The Loans
shall be evidenced by a duly executed and delivered Master Grid Promissory Note
in the form of EXHIBIT A. Each Loan  shall be in an  aggregate  amount not less
than One Hundred Thousand United States Dollars (U.S.  $100,000) and increments
of One Thousand United States Dollars (U.S. $1,000) in excess thereof.  Payment
of principal and interest due with respect to each Loan shall be payable at the
maturity of such Loan and shall be made in funds immediately available to CAPCO
prior to 2 p.m.  San Antonio  time on the day such  payment is due, or as CAPCO
shall  otherwise  direct  from  time to time  and,  subject  to the  terms  and
conditions  hereof,  may  be  repaid  with  the  proceeds  of a  new  borrowing
hereunder. Notwithstanding any provision of this Agreement to the contrary, all
Loans, accrued but unpaid interest and other amounts payable hereunder shall be
due and payable upon  termination of the Facility  (whether by  acceleration or
otherwise).

       5. FACILITY  FEE.  Beginning  with the date of this  Agreement and until
such time as all Loans have been irrevocably repaid to CAPCO in full, and CAPCO
is no longer  obligated  to make Loans,  the Funds (to be  allocated  among the
Funds as the Borrowers deem  appropriate)  may pay to CAPCO a facility fee (the
"Facility  Fee") in the amount up to .04 of one percent (4 basis points) of the
amount of the  Commitment,  as it may be  reduced  pursuant  to  section 6. The
Facility Fee shall be payable  quarterly in arrears  beginning  March 31, 1999,
and upon termination of the Facility (whether by acceleration or otherwise).

       6. OPTIONAL TERMINATION OR REDUCTION OF COMMITMENT.  The Borrowers shall
have the right upon at least three (3) business  days prior  written  notice to
CAPCO,  to terminate or reduce the unused portion of the  Commitment.  Any such
reduction  of the  commitment  shall be in the  amount of Five  Million  United
States Dollars (U.S. $5,000,000) or any larger integral

<PAGE>

multiple of One Million  United  States  Dollars (U.S. $1,000,000) (except that
any reduction may be in the aggregate amount of the unused Commitment). Accrued
fees with respect to the terminated Commitment shall be payable to CAPCO on the
effective date of such termination.

       7. MANDATORY TERMINATION OF THE FACILITY. The Facility,  unless extended
by written  amendment,  shall  automatically  terminate  on the last day of the
Facility Period and any Loans then outstanding  (together with accrued interest
thereon and any other amounts owing hereunder) shall be due and payable on such
date.

       8.  COMMITTED  FACILITY.  CAPCO  acknowledges  that  the  Facility  is a
committed facility and that CAPCO shall be obligated to make any Loan requested
during  the  Facility  Period  under this  Agreement,  subject to the terms and
conditions hereof; provided, however, that CAPCO shall not be obligated to make
any Loan if this Facility has been  terminated by the  Borrowers,  or if at the
time of a  request  for a Loan  by a  Borrower  (on  behalf  of the  applicable
Fund(s)) there exists any Event of Default or condition which, with the passage
of time or giving of notice,  or both,  would  constitute or become an Event of
Default with respect to such Borrower (or such applicable Fund(s)).

       9. LOAN  REQUESTS.  Each request for a Loan (each a "Borrowing  Notice")
shall be in writing by the applicable Borrower(s), except that such Borrower(s)
may make an oral  request  (each an "Oral  Request")  provided  that  each Oral
Request  shall be followed by a written  Borrowing  Notice  within one business
day. Each Borrowing  Notice shall specify the following  terms ("Terms") of the
requested  Loan:  (i) the date on which such Loan is to be disbursed,  (ii) the
principal amount of such Loan,  (iii) the Borrower(s)  which are borrowing such
Loan and the  amount of such Loan to be  borrowed  by each  Borrower,  (iv) the
Funds for whose  benefit the loan is being  borrowed and the amount of the Loan
which is for the benefit of each such Fund, and (v) the requested maturity date
of the Loan.  Each  Borrowing  Notice  shall also set forth the total assets of
each Fund for whose  benefit a portion of the Loan is being  borrowed as of the
close of business on the day  immediately  preceding the date of such Borrowing
Notice.  Borrowing notices shall be delivered to CAPCO by 9:00 a.m. San Antonio
time on the day the Loan is requested to be made.

Each  Borrowing  Notice  shall  constitute  a  representation  to  CAPCO by the
applicable  Borrower(s)  that  all of the  representations  and  warranties  in
Section  12 hereof  are true and  correct  as of such date and that no Event of
Default or other  condition which with the passage of time or giving of notice,
or both, would result in an Event of Default, has occurred or is occurring.

       10.  CONFIRMATIONS;  CREDITING OF FUNDS; RELIANCE BY CAPCO. Upon receipt
by CAPCO of a Borrowing Notice:

               (a)  CAPCO  shall  provide  each  applicable   Borrower  written
       confirmation  of the Terms of such Loan via  facsimile or  telecopy,  as
       soon as reasonably practicable;  provided,  however, that the failure to
       do so shall not affect the obligation of any such

<PAGE>

       Borrower;

               (b) CAPCO shall make such Loan in  accordance  with the Terms by
       transfer  of the Loan  amount in  immediately  available  funds,  to the
       account of the applicable  Borrower(s) as specified in EXHIBIT B to this
       Agreement or as such Borrower(s)  shall otherwise  specify to CAPCO in a
       writing signed by an Authorized Individual (as defined in Section 11) of
       such Borrower(s); and

               (c) CAPCO  shall  make  appropriate  entries  on the Note or the
       records of CAPCO to reflect  the Terms of the Loan;  provided,  however,
       that the  failure  to do so  shall  not  affect  the  obligation  of any
       Borrower.

               (d)  CAPCO  shall be  entitled  to rely  upon and act  hereunder
       pursuant to any Oral Request which it  reasonably  believes to have been
       made by the applicable Borrower through an Authorized Individual. If any
       Borrower  believes that the  confirmation  relating to any Loan contains
       any error or discrepancy from the applicable Oral Request, such Borrower
       will promptly notify CAPCO thereof.

       11.  BORROWING  RESOLUTIONS  AND  OFFICERS'  CERTIFICATES.  Prior to the
making  of any Loan  pursuant  to this  Agreement,  the  Borrowers  shall  have
delivered  to  CAPCO  (a) the  duly  executed  Note,  (b)  Resolutions  of each
Borrower's Trustees or Board of Directors authorizing such Borrower to execute,
deliver and perform  this  Agreement  and the Note on behalf of the  applicable
Funds,  (c) an Officer's  Certificate  in  substantially  the form set forth in
EXHIBIT  D to this  Agreement,  authorizing  certain  individuals  ("Authorized
Individuals"),  to take on behalf of each Borrower (on behalf of the applicable
Funds) actions contemplated by this Agreement and the Note, and (d) the Opinion
of Counsel to USAA Investment  Management  Company,  Manager and Advisor to the
Borrowers, with respect to such matters as CAPCO may reasonably request .

       12.  REPRESENTATIONS  AND WARRANTIES.  In order to induce CAPCO to enter
into this Agreement and to make the Loans provided for hereunder, each Borrower
hereby  makes with  respect to itself,  and as may be  relevant,  the series of
Funds comprising such Borrower,  the following  representations and warranties,
which shall survive the execution and delivery hereof and of the Note:

               (a) ORGANIZATION,  STANDING,  ETC. The Borrower is a corporation
       or trust duly organized,  validly  existing,  and in good standing under
       applicable state laws and has all requisite corporate or trust power and
       authority to carry on its  respective  businesses  as now  conducted and
       proposed to be  conducted,  to enter into this  Agreement  and all other
       documents  to be  executed  by it in  connection  with the  transactions
       contemplated hereby, to issue and borrow under the Note and to carry out
       the terms hereof and thereof;

               (b)  FINANCIAL  INFORMATION;  DISCLOSURE,  ETC. The Borrower has
       furnished CAPCO with certain financial  statements of such Borrower with
       respect to itself and the applicable  Funds, all of which such financial
       statements  have been prepared in

<PAGE>

       accordance with generally  accepted  accounting  principles applied on a
       consistent basis and fairly present the financial  position and  results
       of operations of such Borrower and the applicable Funds on the dates and
       for the periods indicated.   Neither this Agreement  nor  any  financial
       statements,  reports  or  other documents  or  certificates furnished to
       CAPCO by such Borrower or  the  applicable  Funds in connection with the
       transactions  contemplated  hereby contain  any  untrue  statement  of a
       material  fact or omit to state any material  fact necessary to make the
       statements contained herein  or therein in  light  of  the circumstances
       when made not misleading;

               (c)  AUTHORIZATION;   COMPLIANCE  WITH  OTHER  INSTRUMENTS.  The
       execution,  delivery and performance of this Agreement and the Note, and
       borrowings  hereunder,  have  been  duly  authorized  by  all  necessary
       corporate  or trust  action of the  Borrower  and will not result in any
       violation of or be in conflict  with or  constitute a default  under any
       term of the charter,  by-laws or trust agreement of such Borrower or the
       applicable  Funds,  or of any  borrowing  restrictions  or prospectus or
       statement of additional  information  of such Borrower or the applicable
       Funds,  or  of  any  agreement,  instrument,  judgment,  decree,  order,
       statute, rule or governmental regulation applicable to such Borrower, or
       result in the creation of any mortgage, lien, charge or encumbrance upon
       any of the properties or assets of such Borrower or the applicable Funds
       pursuant to any such term. The Borrower and the applicable Funds are not
       in violation of any term of their respective  charter,  by-laws or trust
       agreement,  and  such  Borrower  and  the  applicable  Funds  are not in
       violation of any material  term of any  agreement or instrument to which
       they are a party,  or to the best of such Borrower's  knowledge,  of any
       judgment,  decree,  order,  statute,  rule  or  governmental  regulation
       applicable to them;

               (d) SEC COMPLIANCE. The Borrower and the applicable Funds are in
       compliance  in  all  material   respects  with  all  federal  and  state
       securities  or similar  laws and  regulations,  including  all  material
       rules,  regulations  and  administrative  orders of the  Securities  and
       Exchange Commission (the "SEC") and applicable Blue Sky authorities. The
       Borrower  and the  applicable  Funds are in  compliance  in all material
       respects  with all of the  provisions of the  Investment  Company Act of
       1940,  and such  Borrower  has filed all  reports  with the SEC that are
       required of it or the applicable Funds;

               (e) LITIGATION.  There is no action,  suit or proceeding pending
       or, to the best of the  Borrower's  knowledge,  threatened  against such
       Borrower or the  applicable  Funds in any court or before any arbitrator
       or  governmental  body which seeks to restrain  any of the  transactions
       contemplated by this Agreement or which, if adversely determined,  could
       have a material  adverse effect on the assets or business  operations of
       such  Borrower or the  applicable  Funds or the ability of such Borrower
       and the applicable Funds to pay and perform their obligations  hereunder
       and under the Notes;

               (f) BORROWERS'  RELATIONSHIP  TO FUNDS.  The assets of each Fund
       for whose  benefit  Loans are  borrowed by the  applicable  Borrower are
       subject  to and  liable  for such  Loans and are  available  (except  as
       subordinated to borrowings under the NationsBank

<PAGE>

       committed facility) to the applicable Borrower for the repayment of such
       Loans; and

               (G) YEAR 2000  PREPAREDNESS.  Each  Borrower has (i) initiated a
       review and  assessment  of all areas within its business and  operations
       (including  those  affected by suppliers,  vendors and  customers)  that
       could be  adversely  affected by the "Year 2000  Problem"  (that is, the
       risk that computer  applications  used by such Borrower may be unable to
       recognize  and  perform  properly  date-sensitive   functions  involving
       certain  dates  prior to and any date after  December  31,  1999),  (ii)
       developed a plan and timeline for  addressing the Year 2000 Problem on a
       timely  basis,  and (iii) to date,  implemented  that plan in accordance
       with that timetable.  Based on the foregoing,  such Borrower  reasonably
       believes  that  all  computer  applications  that  are  material  to its
       business and operations are reasonably  expected on a timely basis to be
       able to perform properly  date-sensitive  functions for all dates before
       and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
       the extent that a failure to do so could not  reasonably  be expected to
       have a material  adverse effect on the assets or business  operations of
       such  Borrower or the  applicable  Funds or the ability of such Borrower
       and the applicable Funds to pay and perform their obligations  hereunder
       and under the Note.

       13.  AFFIRMATIVE  COVENANTS  OF THE  BORROWERS.  Until  such time as all
amounts of principal  and  interest due to CAPCO by a Borrower  pursuant to any
Loan made to such Borrower is irrevocably  paid in full, and until the Facility
is terminated, such Borrower (for itself and on behalf of its respective Funds)
agrees:

               (a) To  deliver  to CAPCO as soon as  possible  and in any event
       within  ninety  (90)  days  after  the end of each  fiscal  year of such
       Borrower and the applicable Funds, Statements of Assets and Liabilities,
       Statements of Operations and Statements of Changes in Net Assets of each
       applicable  Fund for such fiscal year,  as set forth in each  applicable
       Fund's Annual Report to shareholders  together with a calculation of the
       maximum  amount  which  each  applicable  Fund  could  borrow  under its
       Borrowing Limit as of the end of such fiscal year;

               (b) To  deliver to CAPCO as soon as  available  and in any event
       within seventy-five (75) days after the end of each semiannual period of
       such  Borrower  and the  applicable  Funds,  Statements  of  Assets  and
       Liabilities,  Statement of Operations  and  Statements of Changes in Net
       Assets of each applicable Fund as of the end of such semiannual  period,
       as set forth in each applicable Funds Semiannual Report to shareholders,
       together with a calculation of the maximum amount which each  applicable
       Fund  could  borrow  under  its  Borrowing  Limit  at the  end  of  such
       semiannual period;

               (c) To deliver to CAPCO prompt  notice of the  occurrence of any
       event or  condition  which  constitutes,  or is likely  to result  in, a
       change in such Borrower or any applicable Fund which could reasonably be
       expected to materially  adversely  affect the ability of any  applicable
       Fund to  promptly  repay  outstanding  Loans made for its benefit or the
       ability of such Borrower to perform its obligations under this Agreement
       or the

<PAGE>

       Note;
               (d) To do, or cause to be done, all things necessary to preserve
       and keep in full force and effect the  corporate  or trust  existence of
       such Borrower and all permits,  rights and privileges  necessary for the
       conduct of its  businesses  and to comply in all material  respects with
       all  applicable  laws,   regulations  and  orders,   including   without
       limitation, all rules and regulations promulgated by the SEC;

               (e) To promptly notify CAPCO of any litigation, threatened legal
       proceeding or  investigation  by a  governmental  authority  which could
       materially  affect the ability of such Borrower or the applicable  Funds
       to promptly  repay the  outstanding  Loans or  otherwise  perform  their
       obligations hereunder;

               (f) In the event a Loan for the benefit of a particular  Fund is
       not repaid in full  within 10 days  after the date it is  borrowed , and
       until  such Loan is repaid in full,  to  deliver  to CAPCO,  within  two
       business  days  after  each  Friday  occurring  after  such 10th day,  a
       statement setting forth the total assets of such Fund as of the close of
       business on each such Friday; and

               (g) Upon the  request  of CAPCO  which may be made by CAPCO from
       time to time in the event  CAPCO in good faith  believes  that there has
       been a material  adverse  change in the capital  markets  generally,  to
       deliver  to CAPCO,  within two  business  days  after  such  request,  a
       statement  setting forth the total assets of each Fund for whose benefit
       a Loan is outstanding on the date of such request.

       14. NEGATIVE COVENANTS OF THE BORROWERS.  Until such time as all amounts
of principal and interest due to CAPCO by a Borrower  pursuant to any Loan made
to such  Borrower  is  irrevocably  paid in full,  and  until the  Facility  is
terminated,  such Borrower (for itself and on behalf of its  respective  Funds)
agrees:

               (a) Not to incur any indebtedness for borrowed money (other than
       pursuant  to the One Hundred  Million  Dollar  ($100,000,000)  committed
       Master  Revolving  Credit  Facility with  NationsBank,  the Five Hundred
       Million  Dollar  ($500,000,000)   uncommitted  Master  Revolving  Credit
       Facility with CAPCO and for overdrafts  incurred at the custodian of the
       Funds from time to time in the  normal  course of  business)  except the
       Loans,  without the prior written  consent of CAPCO,  which consent will
       not be unreasonably withheld; and

               (b) Not to  dissolve or  terminate  its  existence,  or merge or
       consolidate   with  any  other   person  or  entity,   or  sell  all  or
       substantially  all of its  assets in a single  transaction  or series of
       related  transactions  (other than assets  consisting of margin  stock),
       each without the prior written consent of CAPCO,  which consent will not
       be  unreasonably  withheld;  provided  that a Borrower  may without such
       consent merge,  consolidate  with, or purchase  substantially all of the
       assets of, or sell  substantially  all of its  assets to, an  affiliated

<PAGE>

       investment  company or series thereof,  as provided for in Rule 17a-8 of
       the Investment Company Act of 1940.

       15. EVENTS OF DEFAULT. If any of the following events (each an "Event of
Default")  shall  occur  (it being  understood  that an Event of  Default  with
respect to one Fund or Borrower  shall not  constitute an Event of Default with
respect to any other Fund or Borrower):

               (a) Any  Borrower  or  Fund  shall  default  in the  payment  of
       principal or interest on any Loan or any other fee due  hereunder  for a
       period of five (5) days after the same becomes due and payable,  whether
       at maturity or with  respect to any Facility Fee at a date fixed for the
       payment thereof;

               (b) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 13 hereof and such default
       shall not have been  remedied  within  thirty  (30) days  after  written
       notice thereof shall have been given such Borrower or Fund by CAPCO;

               (c) Any Borrower or Fund shall default in the  performance of or
       compliance with any term contained in Section 14 hereof;

               (d) Any  Borrower or Fund shall  default in the  performance  or
       compliance  with any other term contained  herein and such default shall
       not have been  remedied  within  thirty (30) days after  written  notice
       thereof shall have been given such Borrower or Fund by CAPCO;

               (e) Any  representation  or warranty  made by a Borrower or Fund
       herein or pursuant hereto shall prove to have been false or incorrect in
       any material respect when made;

               (f) An event of default shall occur and be continuing  under any
       other facility;  then, in any event, and at any time thereafter,  if any
       Event of Default shall be continuing, CAPCO may by written notice to the
       applicable  Borrower or Fund (i)  terminate the Facility with respect to
       such  Borrower or Fund and (ii)  declare the  principal  and interest in
       respect of any outstanding  Loans with respect to such Borrower or Fund,
       and all other  amounts due  hereunder  with respect to such  Borrower or
       Fund,  to be  immediately  due and payable  whereupon  the principal and
       interest in respect  thereof and all other amounts due  hereunder  shall
       become forthwith due and payable without presentment, demand, protest or
       other  notice of any  kind,  all of which  are  expressly  waived by the
       Borrowers.

       16.  NEW  BORROWERS;  NEW  FUNDS.  So long as no  Event  of  Default  or
condition  which,  with the  passage of time or the giving of notice,  or both,
would  constitute or become an Event of Default has occurred and is continuing,
and with the prior  consent of CAPCO,  which  consent will not be  unreasonably
withheld:

<PAGE>

               (a) Any investment  company that becomes part of the same "group
       of  investment  companies"  (as that term is defined in Rule 11a-3 under
       the  Investment  Company Act of 1940) as the original  Borrowers to this
       Agreement,  may, by  submitting  an amended  Schedule A and Exhibit B to
       this  Agreement to CAPCO (which  amended  Schedule A and Exhibit B shall
       replace the corresponding Schedule and Exhibit which are, then a part of
       this  Agreement)  and  such  other  documents  as CAPCO  may  reasonably
       request,  become a party to this  Agreement  and may become a "Borrower"
       hereunder; and

               (b) A Borrower  may,  by  submitting  an amended  Schedule A and
       Exhibit B to this  Agreement  to CAPCO  (which  amended  Schedule  A and
       Exhibit B shall replace the corresponding Schedule and Exhibit which are
       then a part of this  Agreement),  add additional Funds for whose benefit
       such Borrower may borrow Loans.  No such amendment of Schedule A to this
       Agreement shall amend the Borrowing Limit applicable to any Fund without
       the prior approval of CAPCO.

       17. LIMITED  RECOURSE.  CAPCO agrees (i) that any claim,  liability,  or
obligation  arising  hereunder  or under the Note  whether  on  account  of the
principal of any Loan,  interest thereon,  or any other amount due hereunder or
thereunder  shall be satisfied  only from the assets of the  specific  Fund for
whose  benefit a Loan is  borrowed  and in any event in an amount not to exceed
the outstanding  principal amount of any Loan borrowed for such Fund's benefit,
together  with  accrued and unpaid  interest  due and owing  thereon,  and such
Fund's  share  of any  other  amount  due  hereunder  and  under  the  Note (as
determined in accordance with the provisions hereof) and (ii) that no assets of
any fund shall be used to satisfy any claim,  liability,  or obligation arising
hereunder or under the Note with respect to the outstanding principal amount of
any Loan  borrowed  for the benefit of any other Fund or any accrued and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount
due  hereunder  and  under  the  Note (as  determined  in  accordance  with the
provisions hereof).

       18. REMEDIES ON DEFAULT. In case any one or more Events of Default shall
occur and be continuing, CAPCO may proceed to protect and enforce its rights by
an action at law, suit in equity or other appropriate proceedings,  against the
applicable  Borrower(s)  and/or  Fund(s),  as the case may be. In the case of a
default  in the  payment of any  principal  or  interest  on any Loan or in the
payment of any fee due hereunder,  the relevant  Fund(s) (to be allocated among
such Funds as the Borrowers deem  appropriate)  shall pay to CAPCO such further
amount as shall be  sufficient  to cover the cost and  expense  of  collection,
including, without limitation, reasonable attorney's fees and expenses.

       19. NO WAIVER OF  REMEDIES.  No course of dealing or failure or delay on
the part of CAPCO in exercising any right or remedy hereunder or under the Note
shall  constitute a waiver of any right or remedy  hereunder or under the Note,
nor shall any partial  exercise of any right or remedy  hereunder  or under the
Note preclude any further  exercise  thereof or the exercise of any other right
or remedy  hereunder  or under the Note.  Such  rights and  remedies  expressly
provided are cumulative and not exclusive of any rights or remedies which CAPCO
would otherwise have.

<PAGE>

       20.  EXPENSES.  The  Fund(s)  (to be  allocated  among  the Funds as the
Borrowers deem  appropriate)  shall pay on demand all reasonable  out-of-pocket
costs and expenses (including reasonable attorney's fees and expenses) incurred
by  CAPCO  in  connection  with  the  collection  and  any  other   enforcement
proceedings of or regarding this Agreement, any Loan or the Note.

       21.  BENEFIT OF AGREEMENT.  This Agreement and the Note shall be binding
upon  and  inure  for  the  benefit  of and be  enforceable  by the  respective
successors  and assigns of the parties  hereto;  provided that no party to this
Agreement  or the Note may  assign any of its rights  hereunder  or  thereunder
without the prior written consent of the other parties.

       22.  NOTICES.  All  notices  hereunder  and all  written,  facsimile  or
telecopied  confirmations  of Oral Requests made hereunder shall be sent to the
Borrowers as indicated on EXHIBIT B and to CAPCO as indicated on EXHIBIT C.

       23.  MODIFICATIONS.  No provision  of this  Agreement or the Note may be
waived,  modified  or  discharged  except by mutual  written  agreement  of all
parties. THIS WRITTEN LOAN AGREEMENT AND THE NOTE REPRESENT THE FINAL AGREEMENT
BETWEEN  THE  PARTIES  AND  MAY  NOT BE  CONTRADICTED  BY  EVIDENCE  OF  PRIOR,
CONTEMPORANEOUS  OR SUBSEQUENT  ORAL  AGREEMENTS  OF THE PARTIES.  THERE ARE NO
UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

       24. GOVERNING LAW AND JURISDICTION.  This Agreement shall be governed by
and construed in accordance  with the laws of the state of Texas without regard
to the choice of law provisions thereof.

       25. TRUST  DISCLAIMER.  Neither the  shareholders,  trustees,  officers,
employees and other agents of any Borrower or Fund shall be personally bound by
or liable for any indebtedness,  liability or obligation hereunder or under the
Note nor shall resort be had to their private  property for the satisfaction of
any obligation or claim hereunder.

copies hereof and return one to us,  whereupon this Agreement  shall be binding

       FOR VALUE  RECEIVED,  each of the  undersigned  (each a  "Borrower"  and
collectively the "Borrowers"),  severally and not jointly, on behalf of and for
the benefit of the series of funds  comprising  each such Borrower as listed on
Schedule A to the  Agreement as defined  below (each a "Fund" and  collectively
the "Funds") promises to pay to the order of USAA Capital Corporation ("CAPCO")
at CAPCO's  office  located at 9800  Fredericksburg  Road,  San Antonio,  Texas
78288,  in  lawful  money of the  United  States  of  America,  in  immediately
available  funds,  the  principal  amount  of all  Loans  made by CAPCO to such
Borrower for the benefit of the applicable  Funds under the Facility  Agreement
Letter dated January 12, 1999 (as amended or modified, the "Agreement"),  among
the  Borrowers and CAPCO,  together with interest  thereon at the rate or rates
set forth in the Agreement.  All payments of interest and principal outstanding
shall be made in accordance with the terms of the Agreement.

       This Note  evidences  Loans made  pursuant  to, and is  entitled  to the
benefits  of,  the  Agreement.  Terms not  defined in this Note shall be as set
forth in the Agreement.

       CAPCO is authorized to endorse the  particulars  of each Loan  evidenced
hereby  on  the  attached  Schedule  and  to  attach  additional  Schedules  as
necessary,  provided  that the failure of CAPCO to do so or to do so accurately
shall not affect the obligations of any Borrower (or the Fund for whose benefit
it is borrowing) hereunder.

       Each Borrower waives all claims to  presentment,  demand,  protest,  and
notice  of  dishonor.  Each  Borrower  agrees  to pay all  reasonable  costs of
collection,  including  reasonable  attorney's  fees  in  connection  with  the
enforcement of this Note.

       CAPCO hereby agrees (i) that any claim, liability, or obligation arising
hereunder  or under the  Agreement  whether on account of the  principal of any
Loan,  interest thereon,  or any other amount due hereunder or thereunder shall
be satisfied only from the assets of the specific Fund for whose benefit a Loan
is  borrowed  and in any  event in an  amount  not to  exceed  the  outstanding
principal  amount of any Loan borrowed for such Fund's  benefit,  together with
accrued and unpaid interest due and owing thereon, and such Fund's share of any
other amount due hereunder and under the Agreement (as determined in accordance
with the provisions of the Agreement) and (ii) that no assets of any Fund shall
be used to satisfy any claim,  liability,  or obligation  arising  hereunder or
under the Agreement  with respect to the  outstanding  principal  amount of any
Loan  borrowed  for the  benefit  of any other Fund or any  accrued  and unpaid
interest  due and owing  thereon or such other Fund's share of any other amount
due hereunder

of any  Borrower  or Fund  shall  be  personally  bound  by or  liable  for any
indebtedness,  liability  or  obligation  hereunder or under the Note nor shall
resort be had to their private  property for the satisfaction of any obligation
or claim hereunder.

       Loans under the Agreement and this Note are  subordinated  to loans made
under the  $100,000,000  364-day  committed  Mater  Revolving  Credit  Facility
Agreement  between the Borrowers and  NationsBank,  N.A.  (NationsBank),  dated
January 13,  1999,  in the manner and to the extent set forth in the  Agreement
among the Borrowers, CAPCO and NationsBank, dated January 13, 1999.

         This Note shall be governed by the laws of the state of Texas.
