WHO MAY WANT TO INVEST IN THE FUNDS?

The funds may be a good investment if you

>>   are seeking current income

>>   prefer a  relatively  safe  investment  over one  that may  provide  better
     long-term investment returns

>>   are comfortable with the funds' other investment risks

WHO MAY NOT WANT TO INVEST IN THE FUNDS?

The funds may not be a good investment if you are

>>   investing for long-term growth

>>   looking for the added security of FDIC insurance

**********LEFT MARGIN CALLOUTS

DEBT  SECURITIES  include  fixed  income  investments  such  as  notes,   bonds,
commercial paper and Treasury bills.

o    An investment in the funds is not a bank deposit,  and it is not insured or
     guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
     government  agency.  Although  the money  market funds seek to preserve the
     value of your  investment at $1.00 per share,  it is possible to lose money
     by investing in them.

INFORMATION ABOUT THE FUNDS

CAPITAL PRESERVATION FUND
GOVERNMENT AGENCY MONEY MARKET FUND

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

The funds are money market funds that seek maximum safety and liquidity and seek
to pay shareholders  the highest rate of return  consistent with this objective.
In  addition,  Government  Agency  Money  Market  seeks to  purchase  only those
securities with income that will be exempt from state income tax.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?

The funds buy very  short-term U.S.  Treasury  securities that are guaranteed by
the direct full faith and credit pledge of the U.S. government.

Government Agency Money Market also buys other very short-term securities issued
by the U.S. government, its agencies and instrumentalities.  The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.

The funds may purchase  securities in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

WHAT IS THE DIFFERENCE BETWEEN THE TWO FUNDS?

The funds differ in the types of  securities  that they may buy, as shown on the
table below.

<TABLE>
Type of Security                    Capital Preservation       Government Agency Money Market
- ----------------------------------- -------------------------- -----------------------------------------
<S>                                <C>                         <C>
U.S. Treasury                       Yes                        Yes
U.S. government agency              No                         Yes
U.S. government instrumentality     No                         Yes
</TABLE>

U.S. Treasury  securities are believed to be the safest securities  because they
are

>>   supported by the  government's  full faith and credit  pledge;  this is the
     highest credit quality available

>>   the most widely traded and most liquid securities investors can buy

Other types of U.S.  government  securities do not necessarily  feature the full
faith and credit nor the liquidity of market that U.S.  Treasury  securities do.
On the other hand, other U.S. government securities generally have higher yields
than U.S. Treasury securities

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUNDS?

Because very short-term  securities are among the safest  securities  available,
the  interest  they  pay is  among  the  lowest  for  income-paying  securities.
Accordingly,  the yield on these  funds  will  likely be lower  than  funds that
invest in longer-term or lower-quality securities.






SHORT-TERM TREASURY FUND
INTERMEDIATE-TERM TREASURY FUND
LONG-TERM TREASURY FUND

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These funds seek the highest  level of current  income  exempt from state income
tax while maintaining safety of capital.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?

The funds buy U.S. Treasury  securities  guaranteed by the direct full faith and
credit pledge of the U.S. government.

The funds also may buy securities  issued by the U.S.  government,  its agencies
and instrumentalities.  The U.S. government provides varying levels of financial
support to these agencies and  instrumentalities.  The fund may invest up to 35%
of its total assets in these  securities.  In  addition,  the funds can only buy
U.S. government securities with income that is exempt from state income tax.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

WHAT IS THE DIFFERENCE BETWEEN THE THREE FUNDS?

The funds  differ in the maturity of the debt  securities  they  purchase.  This
difference is shown on the chart below.

                                      Expected Weighted Average Maturity
                                      Range
- ---------------------------------------------------------------------------
Short-Term Treasury                   13 months-3 years
Intermediate-Term Treasury            3-10 years
Long-Term Treasury                    20-30 years

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUNDS?

The funds have different weighted average maturities. Because of this, the funds
will  respond  differently  to  changes in  interest  rates.  Funds with  longer
weighted  average  maturities are more sensitive to interest rate changes.  When
interest  rates rise,  the values of the funds usually  fall,  but the values of
funds with longer weighted average maturities generally will fall farther.

The funds' share values will fluctuate.  In general,  the funds that have higher
potential  income  have a higher  potential  loss.  If you sell your shares when
their value is less than the price you paid, you will lose money.

                                    Potential Income             Potential Loss
- -------------------------------------------------------------------------------
Short-Term Treasury                 Lower                        Lower
Intermediate-Term Treasury          Moderate                     Moderate
Long-Term Treasury                  Higher                       Higher






INFLATION-ADJUSTED TREASURY FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Inflation-Adjusted  Treasury seeks total return  consistent  with  investment in
U.S. Treasury inflation-adjusted securities.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys  inflation-indexed  U.S.  Treasury  securities  guaranteed  by the
direct   full  faith  and   credit   pledge  of  the  U.S.   government.   These
inflation-indexed securities are designed to protect the future purchasing power
of the money invested in them.

The fund also may buy U.S. Treasury  securities that are not  inflation-indexed.
The fund may invest up to 35% of its total assets in these securities.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Inflation-adjusted  securities  are sold  based  upon an  assumption  about real
interest rates.  "Real" interest rates are the market rate of interest minus the
anticipated rate of inflation.  Changes in real interest rates affect the amount
of income the fund  generates.  Generally,  when real interest  rates rise,  the
fund's  share  value will  decline.  The  opposite is true when  interest  rates
decline. This real interest rate risk is higher for Inflation-Adjusted  Treasury
than for funds that do not invest in inflation-indexed securities.

As  with  all  funds,   at  any  given  time,   the  value  of  your  shares  of
Inflation-Adjusted  Treasury  may be worth more or less than the price you paid.
If you sell your shares when the value is less than the price you paid, you will
lose money.







SHORT-TERM GOVERNMENT FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Short-Term  Government  seeks high current  income while  maintaining  safety of
principal.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys short-term securities issued by the U.S. government,  its agencies
and instrumentalities, including mortgage-backed securities. The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.  The fund also may buy short-term  U.S.  Treasury  securities
guaranteed by the direct full faith and credit pledge of the U.S. government.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

The weighted average maturity of the fund is expected to be three years or less.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Interest rate changes affect the amount of income the fund generates. Generally,
when interest rates rise,  the fund's share value will decline.  The opposite is
true when  interest  rates  decline.  This  interest  rate  risk is  higher  for
Short-Term  Government  than  for  funds  that  have  shorter  weighted  average
maturities, such as money market funds.

Short-Term  Government  invests in mortgage-backed  securities.  When homeowners
refinance their mortgages to take advantage of declining  interest rates,  their
existing  mortgages  are  prepaid.  The  mortgages,  which  back the  securities
purchased by Short-Term Government,  may be prepaid in this fashion.  Because of
this "prepayment  risk," the fund may benefit less from declining interest rates
than other short-term funds.

As with all  funds,  at any given  time the value of your  shares of  Short-Term
Government  may be worth more or less than the price you paid.  If you sell your
shares when the value is less than the price you paid, you will lose money.







GNMA FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Short-Term  Government  seeks high current  income while  maintaining  safety of
principal.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys short-term securities issued by the U.S. government,  its agencies
and instrumentalities, including mortgage-backed securities. The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.  The fund also may buy short-term  U.S.  Treasury  securities
guaranteed by the direct full faith and credit pledge of the U.S. government.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

The weighted average maturity of the fund is expected to be three years or less.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Interest rate changes affect the amount of income the fund generates. Generally,
when interest rates rise,  the fund's share value will decline.  The opposite is
true when  interest  rates  decline.  This  interest  rate  risk is  higher  for
Short-Term  Government  than  for  funds  that  have  shorter  weighted  average
maturities, such as money market funds.

Short-Term  Government  invests in mortgage-backed  securities.  When homeowners
refinance their mortgages to take advantage of declining  interest rates,  their
existing  mortgages  are  prepaid.  The  mortgages,  which  back the  securities
purchased by Short-Term Government,  may be prepaid in this fashion.  Because of
this "prepayment  risk," the fund may benefit less from declining interest rates
than other short-term funds.

As with all  funds,  at any given  time the value of your  shares of  Short-Term
Government  may be worth more or less than the price you paid.  If you sell your
shares when the value is less than the price you paid, you will lose money.








BASICS OF FIXED INCOME INVESTING

DEBT SECURITIES

When a fund buys a debt security,  which is also called a fixed-income security,
it is  essentially  lending money to the issuer of the security.  Notes,  bonds,
commercial paper and Treasury bills are examples of debt  securities.  After the
issuer  first  sells  the  debt  security,  it may be  bought  and sold by other
investors.  The price of the  security  may rise or fall based on many  factors,
including changes in interest rates, inflation and liquidity.

The fund managers decide which debt securities to buy and sell by

>>   determining which securities help a fund meet its maturity requirements

>>   identifying securities that satisfy a fund's credit quality requirements

>>   evaluating  the  current  economic  conditions  and  assessing  the risk of
     inflation

>>   evaluating  special  features of the securities  that may make them more or
     less attractive

WEIGHTED AVERAGE MATURITY

Like most loans,  debt  securities  eventually must be repaid (or refinanced) at
some date.  This date is called the maturity  date. The number of days left to a
debt  security's  maturity date is called the remaining  maturity.  The longer a
debt  security's  remaining  maturity,  the more  sensitive  it is to changes in
interest rates.

Because a bond fund will own many debt securities,  the fund managers  calculate
the average of the remaining  maturities of all of the debt  securities the fund
owns to evaluate the interest rate  sensitivity  of the entire  portfolio.  This
average is weighted according to the size of the fund's individual  holdings and
is called  WEIGHTED  AVERAGE  MATURITY.  The  following  chart  shows how a fund
manager would calculate the weighted average maturity for a fund that owned only
two debt securities.

</TABLE>

TYPES OF RISK

The basic types of risk that the funds face are described below.

INTEREST RATE RISK

Generally,  interest  rates and the prices of debt  securities  move in opposite
directions.  So when  interest  rates fall,  the prices of most debt  securities
rise; when interest rates rise, prices fall.  Because the funds invest primarily
in  debt   securities,   changes  in  interest  rates  will  affect  the  funds'
performance.

The degree to which interest rate changes affect the funds'  performance  varies
and is related to the weighted average maturity of each fund. For example,  when
interest  rates rise, you can expect the share value of a long-term bond fund to
fall more than that of a short-term  bond fund. When rates fall, the opposite is
true. This sensitivity to interest rate changes is called interest rate risk.

***********LEFT MARGIN CALLOUTS
WEIGHTED  AVERAGE  MATURITY is a tool that the fund managers use to  approximate
the remaining maturity of a fund's investment portfolio.

     changes in interest rates.

***********END  LEFT MARGIN  CALLOUTS 



When interest rates change, longer maturity bonds experience a greater change in
price.  The following  table shows the effect of a 1% increase in interest rates
on the price of 7% coupon bonds of differing maturities:

</TABLE>

CREDIT RISK

Credit risk is the risk that an obligation won't be paid and a loss will result.
A high  credit  rating  indicates  a high  degree of  confidence  by the  rating
organization  that  the  issuer  will  be able to  withstand  adverse  business,
financial or economic  conditions  and be able to make  interest  and  principal
payments on time.  Generally,  a lower credit rating indicates a greater risk of
non-payment.  A lower rating also may indicate that the issuer has a more senior
series of debt  securities,  which  means that if the  issuer  has  difficulties
making  its  payments,  the  more  senior  series  of debt is  first in line for
payment.

It's not as simple as buying the  highest-rated  debt securities.  Higher credit
ratings   usually  mean  lower  interest  rates,  so  investors  often  purchase
securities that aren't the highest rated to increase return. If a fund purchases
lower-rated securities, it assumes additional credit risk.

While U.S.  government  securities are not rated, they are generally regarded as
having the equivalent of the highest credit quality available. Because the funds
offered by this Prospectus invest in government securities,  they are considered
to have very low credit risk.

LIQUIDITY RISK

Debt securities can become  difficult to sell for a variety of reasons,  such as
lack of an active trading market.  When a fund's investments become difficult to
sell, it is said to have a problem with  liquidity.  The chance that a fund will
have liquidity issues is called liquidity risk.

INFLATION RISK

The safest investments usually have the lowest potential income and performance.
There  is  a  risk,   then,  that  returns  from  the  investment  may  fail  to
significantly  outpace  inflation.  Even if the value of your investment has not
gone  down,  your  money  will  not be  worth  as much as if  there  had been no
inflation.  Your after-inflation  return may be quite small. This risk is called
inflation risk.

MANAGEMENT

WHO MANAGES THE FUNDS?

The Board of  Trustees,  investment  advisor and fund  management  team play key
roles in the management of the funds.

THE BOARD OF TRUSTEES

The Board of Trustees  oversees the  management  of the funds and meets at least
quarterly  to  review  reports  about  fund  operations.  Although  the Board of
Trustees does not manage the funds, it has hired an investment advisor to do so.
More than half of the trustees are independent of the funds'  advisor,  that is,
they are not employed by and have no financial interest in the advisor.

THE INVESTMENT ADVISOR

The funds' investment  advisor is American Century Investment  Management,  Inc.
The advisor has been  managing  mutual  funds  since 1958.  American  Century is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible  for managing the investment  portfolios of the funds
and directing the purchase and sale of their investment securities.  The advisor
also arranges for transfer agency,  custody and all other services necessary for
the funds to operate.

For the services it provided to the funds during their most recent  fiscal year,
the  advisor  received a unified  management  fee based on a  percentage  of the
average net assets of the Investor Class of shares of each fund. The rate of the
management fee for a fund is determined on a class-by-class  basis monthly using
a two-step  formula that takes into account the fund's  strategy  (money market,
bond or equity) and the total amount of mutual fund assets the advisor manages.

The Statement of Additional  Information contains detailed information about the
calculation  of the  management  fee.  Out of that  fee,  the  advisor  paid all
expenses of managing and operating the fund except  brokerage  expenses,  taxes,
interest,  fees and  expenses  of the  independent  directors  (including  legal
counsel fees) and extraordinary expenses.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio  managers,  assistant portfolio managers and
analysts to manage the funds.  Teams meet regularly to review portfolio holdings
and to discuss purchase and sale activity.  Team members buy and sell securities
for a fund as they  see fit,  guided  by the  fund's  investment  objective  and
strategy.

o    CODE OF ETHICS
     American Century has a Code of Ethics designed to ensure that the interests
     of fund shareholders come before the interests of the people who manage the
     funds.  Among  other  provisions,  the Code of Ethics  prohibits  portfolio
     managers  and other  investment  personnel  from  buying  securities  in an
     initial public offering or from profiting from the purchase and sale of the
     same  security  within 60 calendar  days.  In addition,  the Code of Ethics
     requires  portfolio managers and other employees with access to information

FUNDAMENTAL INVESTMENT POLICIES

Fundamental  investment  policies  contained  in  the  Statement  of  Additional
Information  and the  investment  objectives  of the  funds  may not be  changed
without a shareholder  vote. The Board of Trustees may change any other policies
and investment strategies.

YEAR 2000 ISSUES

Many of the world's  computer  systems were originally  programmed in a way that
prevented   them  from  properly   recognizing   or  processing   date-sensitive
information  relating to the Year 2000 and beyond.  Because  this may impact the
computer  systems of various  American  Century-affiliated  and external service
providers  for the  funds,  American  Century  formally  initiated  a Year  2000
readiness  project in July 1997.  It involves a team of  information  technology
professionals  assisted  by outside  consultants  and  guided by a  senior-level
steering committee.  The team's goal is to assess the impact of the Year 2000 on
American Century's systems,  renovate or replace  noncompliant  critical systems
and test  those  systems.  In  addition,  the team has been  working  to  gather
information  about the Year 2000  efforts  of the  funds'  other  major  service
providers.

Although  American Century believes its critical systems will function  properly
in the Year 2000, this is not guaranteed.  If the efforts of American Century or
its  external  service  providers  are  not  successful,  the  funds'  business,
particularly the provision of shareholder services, may be hampered.

In  addition,  the  issuers  of  securities  the funds own could  have Year 2000
computer  problems.  These problems could  negatively  affect the value of their
securities, which, in turn, could impact the funds' performance. The advisor has
established a process to gather publicly  available  information  about the Year
2000  readiness  of these  issuers.  However,  this  process may not uncover all
relevant  information,  and the  information  gathered  may not be complete  and
accurate.  Moreover, an issuer's Year 2000 readiness is only one of many factors
the fund  managers  may consider  when making  investment  decisions,  and other
factors may receive greater weight.

MINIMUM INITIAL INVESTMENT AMOUNTS

To open an account the minimum investments are as follows:
- --------------------------------------------------------------------------------
Individual or Joint                                                  $2,500

403(b)                                                           No minimum

REDEMPTION OF SHARES IN LOW-BALANCE ACCOUNTS

If your  redemption  activity  causes  your  account  balance  to fall below the
minimum  initial  investment  amount we will  notify you and give you 90 days to
meet the minimum. If you do not meet the deadline,  American Century will redeem
the shares in the account and send the proceeds to your address of record.

ABUSIVE TRADING PRACTICES
We do not permit market-timing or other abusive trading practices in our funds.

Excessive,  short-term  (market-timing)  or other abusive trading  practices may
disrupt portfolio management  strategies and harm fund performance.  To minimize
harm to the funds and their  shareholders,  we  reserve  the right to reject any
purchase order (including  exchanges) from any investor we believe has a history
of  abusive  trading  or  whose  trading,  in our  judgment,  has been or may be
disruptive to a fund. In making this judgment,  we may consider  trading done in
multiple  accounts under common ownership or control.  We also reserve the right
to delay delivery of your  redemption  proceeds - up to seven days - or to honor
certain redemptions with securities,  rather than cash, as described in the next
section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS
If,  during any 90-day  period,  you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than  $250,000),  we
reserve  the right to pay part or all of the  redemption  proceeds  in excess of
this amount in readily marketable securities instead of cash. If we make payment
in securities,  we will value the securities,  selected by the fund, in the same
manner as we do in computing  the fund's net asset value.  We may provide  these
securities in lieu of cash without prior notice.

If your  redemption  would  exceed  this limit and you would like to avoid being
paid in  securities,  please  provide us with an  unconditional  instruction  to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur.  The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the  transaction.  This  minimizes the effect of the
redemption on the fund and its remaining shareholders.

INVESTING THROUGH FINANCIAL INTERMEDIARIES

If you do business  with us through a  FINANCIAL  INTERMEDIARY  or a  retirement
plan,  your ability to purchase,  exchange and redeem  shares will depend on the
policies of that entity. Some policy differences may include

o        minimum investment requirements
o        exchange policies
o        fund choices
o        cut-off time for investments

Please  contact  your  financial  intermediary  or plan  sponsor  for a complete
description  of its policies.  Copies of the funds' annual  reports,  semiannual
reports  and  Statements  of  Additional  Information  are  available  from your
intermediary or plan sponsor.

Certain  financial  intermediaries  perform for their clients  recordkeeping and
administrative  services that would otherwise be performed by American Century's
transfer agent.  In some  circumstances,  American  Century will pay the service
provider a fee for performing those services.

Although  transactions in fund shares may be made directly with American Century
at no charge,  you also may purchase,  redeem and exchange  fund shares  through
financial  intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

American Century has contracts with certain financial  intermediaries  requiring
them to track the time investment orders are received. The funds have authorized
those  intermediaries  to accept  orders on their behalf up to the time at which
the net asset value is determined.  If those orders are  transmitted to American
Century and paid for in accordance with the contract, they will be priced at the
net asset  value next  determined  after your  request is  received  in the form
required by the intermediary on a fund's behalf.

SHARE PRICE AND DISTRIBUTIONS

SHARE PRICE

American Century  determines the NET ASSET VALUE of the funds as of the close of
regular  trading on the New York Stock  Exchange  (usually 4 p.m.  Eastern time)
each day the Exchange is open.  On days when the Exchange is not open, we do not
calculate  the net  asset  value.  The net  asset  value of a fund  share is the
current value of the fund's investments,  minus any liabilities,  divided by the
number of fund shares outstanding.

If current market prices of securities owned by a fund are not readily available
from an independent pricing service,  the advisor may determine their fair value
in accordance with procedures  adopted by the fund's Board of Trustees.  Trading
of securities in foreign markets may not take place on every day the Exchange is
open.  Also,  trading in some  foreign  markets  may take place on  weekends  or
holidays  when a fund's net asset  value is not  calculated.  So, the value of a
fund's  portfolio  may be  affected  on days when you can't  purchase  or redeem
shares of the fund.

We will price your purchase,  exchange or redemption at the net asset value next
determined after we receive your transaction request in good order.

DISTRIBUTIONS

Federal tax laws require each fund to make  distributions to its shareholders in
order  to  qualify  as a  "regulated  investment  company."  Qualification  as a
regulated investment company means that the fund will not be subject to state or
federal income tax on amounts distributed.  The distributions  generally consist
of dividends and interest  received,  as well as CAPITAL  GAINS  realized on the
sale of investment  securities.  Each money market fund  declares  distributions
from net income daily.  These  distributions are paid on the last Friday of each
month. Each of the other funds pays distributions from net income monthly.  Each
fund (except the money market funds)  generally  pays  distributions  of capital
gains,  if  any,  once  a year  in  December.  A fund  may  make  more  frequent
distributions if necessary to comply with Internal Revenue Code provisions.

You will begin to participate in fund  distributions the day after your purchase
is effective.  If you redeem shares, you will receive the distribution  declared
for  the day  you  redeem.  If you  redeem  all  shares,  we  will  include  the
distributions on the redeemed with your redemption proceeds.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions.  For shareholders  investing  through taxable  accounts,  we will
reinvest  distributions unless you elect to receive them in cash. Please consult
our Investor Services Guide for further information regarding  distributions and
your distribution options.

**********LEFT MARGIN CALLOUTS

The NET ASSET VALUE of a fund is the price of the fund's shares.

CAPITAL GAINS are increases in the values of capital assets, such as stock, from
the time the assets are  purchased.  Tax  becomes  due on capital  gains once an
asset is sold.

**********END LEFT MARGIN CALLOUTS






TAXES

The tax  consequences  of  owning  shares of the funds  will vary  depending  on
whether you own them through a taxable or tax-deferred account. Tax consequences
result from distributions by the funds of dividend and interest income they have
received  and  capital  gains  they  have  generated  through  their  investment
activities.  Tax consequences also result from sales of fund shares by investors
after the net asset value has increased or decreased.

TAX-DEFERRED ACCOUNTS

If you purchase fund shares through a tax-deferred  account, such as an IRA or a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  usually will not be subject to current taxation,  but will
accumulate in your account  under the plan on a  tax-deferred  basis.  Likewise,
moving  from one fund to  another  fund  within a plan or  tax-deferred  account
generally  will  not  cause  you to be  taxed.  For  information  about  the tax
consequences of making  purchases or withdrawals  through an  employer-sponsored
retirement  or  savings  plan,  or  through  an IRA,  please  consult  your plan
administrator, your summary plan description or a professional tax advisor.

TAXABLE ACCOUNTS

If you own fund shares through a taxable account,  distributions by the fund and
sales by you of fund shares may cause you to be taxed.

TAXABILITY OF DISTRIBUTIONS

Fund distributions may consist of income earned by the fund from sources such as
dividends  and  interest,  or  capital  gains  generated  from  the sale of fund
investments. Distributions of income are taxed as ordinary income. Distributions
of capital gains are classified  either as short-term or long-term and are taxed
as follows:


<TABLE>
Type of distribution               Tax rate for 15% bracket             Tax rate for 28% bracket or above
- --------------------------- ---------------------------------------- -----------------------------------------
<S>                                           <C>                                      <C>
Short-term capital gains             Ordinary income rate                      Ordinary income rate
Long-term capital gains                       10%                                      20%
</TABLE>

The tax status of any  distribution  of capital  gains is determined by how long
the fund held the  underlying  security that was sold,  not by how long you have
been  invested  in the  fund or  whether  you  reinvest  your  distributions  in
additional  shares or take them as income.  American Century will detail the tax
status of fund  distributions  for each  calendar  year in an annual tax mailing
(Form 1099) from the fund.

Distributions may also be subject to state and local taxes.  Because  everyone's
tax situation is unique,  always  consult your tax  professional  about federal,
state and local tax consequences.

TAXES ON TRANSACTIONS

Your  redemptions -- including  exchanges to other American Century funds -- are
subject to capital  gains tax.  The table above can provide a general  guide for
your potential tax liability when selling or exchanging fund shares.  Short-term
capital  gains are gains on fund  shares  held for 12 months or less.  Long-term
capital  gains are gains on fund  shares  held for more than 12 months.  If your
shares  decrease in value,  their sale or exchange will result in a long-term or
short-term  capital loss.  However,  you should note that any loss realized upon
the sale or  redemption of shares held for six months or less will be treated as
a long-term  capital loss to the extent of any distribution of long-term capital
gain to you with respect to such shares. If a loss is realized on the redemption
of fund shares, the reinvestment in additional fund shares within 30 days before
or after the  redemption  may be subject to the wash sale rules of the  Internal
Revenue Code,  resulting in a postponement  of the  recognition of such loss for
federal  income tax  purposes.  If you have not certified to us that your social
security  number or tax  identification  number is correct  and that you are not
subject to 31% withholding, we are required to withhold and remit to the IRS 31%
of dividends, capital gains distributions and redemptions.

**********LEFT MARGIN CALLOUTS

o    BUYING A DIVIDEND
     Purchasing  fund shares in a taxable  account shortly before a distribution
     is sometimes known as buying a dividend. In taxable accounts,  you must pay
     income taxes on the  distribution  whether you reinvest the distribution or
     take  it in  cash.  In  addition,  you  will  have  to  pay  taxes  on  the
     distribution whether the value of your investment  decreased,  increased or
     remained the same after you bought the fund shares.

     The risk in  buying a  dividend  is that a fund's  portfolio  may  build up
     taxable  gains  throughout  the  period  covered  by  a  distribution,   as
     securities  are sold at a profit.  We distribute  those gains to you, after
     subtracting  any losses,  even if you did not own the shares when the gains
     occurred.

     If you buy a dividend, you incur the full tax liability of the distribution
     period, but you may not enjoy the full benefit of the gains realized in the
     fund's portfolio.

MULTIPLE CLASS INFORMATION

American  Century  offers  two  classes  of  all of the  funds  (except  Capital
Preservation):  Investor Class and Advisor Class.  Capital  Preservation  offers
only an Investor  class of shares.  The shares  offered by this  Prospectus  are
Investor Class shares and have no up-front or deferred charges,  commissions, or
12b-1 fees.

American  Century  offers the other class of shares  primarily to  institutional
investors,    through    institutional    distribution    channels,    such   as
employer-sponsored  retirement  plans,  or  through  banks,  broker-dealers  and
insurance  companies.  The other  class has  different  fees,  expenses,  and/or
minimum  investment  requirements than the Investor Class. The difference in the
fee structures  among the classes is the result of their  separate  arrangements
for shareholder and  distribution  services and not the result of any difference
in  amounts  charged  by the  advisor  for core  investment  advisory  services.
Accordingly,  the  core  investment  advisory  expenses  do not  vary by  class.
Different fees and expenses will affect performance.  For additional information
concerning the other classes of shares not offered by this  Prospectus,  call us
at  1-800-345-3533  for  Advisor  Class  shares.  You also may  contact  a sales
representative or financial intermediary who offers that class of shares.

Except as  described  below,  all  classes  of  shares of a fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only  differences  among the various classes are (a) each class
may be subject to different  expenses specific to that class, (b) each class has
a different identifying designation or name, (c) each class has exclusive voting
rights with respect to matters solely  affecting such class,  and (d) each class
may have different exchange privileges.






Financial Highlights

UNDERSTANDING THE FINANCIAL HIGHLIGHTS

The tables on the next few pages  itemize  what  contributed  to the  changes in
share  price  during the  period.  They also show the changes in share price for
this period in  comparison  to changes over the last five fiscal years (or less,
if the share class is not five years old).

On a per-share basis, each table includes:

o share price at the beginning of the period
o investment income and capital gains or losses
o distributions of income and capital gains paid to shareholders
o share price at the end of the period

year,  this section will feature  charts that show Annual Total Returns  Highest
and Lowest Quarterly  Returns Average Annual Returns,  including a comparison of
these returns to a benchmark index for the Advisor Class of the fund

In addition,  investors can examine the performance of the fund's Investor Class
of shares. The Investor Class has a total expense ratio that is 0.25% lower than
the  Advisor  Class.  If the  Advisor  Class  had  existed  during  the  periods
presented,  its  performance  would  have been lower  because of the  additional
expense.

INFORMATION ABOUT THE FUNDS

GOVERNMENT AGENCY MONEY MARKET FUND

WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

The fund is a money  market fund that seeks  maximum  safety and  liquidity  and
seeks to pay  shareholders  the  highest  rate of  return  consistent  with this
objective.  In addition,  Government  Agency Money Market seeks to purchase only
those securities with income that will be exempt from state income tax.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?

The fund buys very  short-term U.S.  Treasury  securities that are guaranteed by
the direct full faith and credit pledge of the U.S. government.

Government Agency Money Market also buys other very short-term securities issued
by the U.S. government, its agencies and instrumentalities.  The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.


WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Because very short-term  securities are among the safest  securities  available,
the  interest  they  pay is  among  the  lowest  for  income-paying  securities.
Accordingly,  the yield on this fund will likely be lower than funds that invest
in longer-term or lower-quality securities.






SHORT-TERM TREASURY FUND
INTERMEDIATE-TERM TREASURY FUND
LONG-TERM TREASURY FUND

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These funds seek the highest  level of current  income  exempt from state income
tax while maintaining safety of capital.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?

The funds buy U.S. Treasury  securities  guaranteed by the direct full faith and
credit pledge of the U.S. government.

The funds also may buy securities  issued by the U.S.  government,  its agencies
and instrumentalities.  The U.S. government provides varying levels of financial
support to these agencies and  instrumentalities.  The fund may invest up to 35%
of its total assets in these  securities.  In  addition,  the funds can only buy
U.S. government securities with income that is exempt from state income tax.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

WHAT IS THE DIFFERENCE BETWEEN THE THREE FUNDS?

The funds  differ in the maturity of the debt  securities  they  purchase.  This
difference is shown on the chart below.

                                        Expected Weighted Average Maturity
                                        Range
- -----------------------------------------------------------------------------
Short-Term Treasury                     13 months-3 years
Intermediate-Term Treasury              3-10 years
Long-Term Treasury                      20-30 years

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUNDS?

The funds have different weighted average maturities. Because of this, the funds
will  respond  differently  to  changes in  interest  rates.  Funds with  longer
weighted  average  maturities are more sensitive to interest rate changes.  When
interest  rates rise,  the values of the funds usually  fall,  but the values of
funds with longer weighted average maturities generally will fall farther.

The funds' share values will fluctuate.  In general,  the funds that have higher
potential  income  have a higher  potential  loss.  If you sell your shares when
their value is less than the price you paid, you will lose money.

                                     Potential Income             Potential Loss
- --------------------------------------------------------------------------------
Short-Term Treasury                  Lower                        Lower
Intermediate-Term Treasury           Moderate                     Moderate
Long-Term Treasury                   Higher                       Higher






INFLATION-ADJUSTED TREASURY FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Inflation-Adjusted  Treasury seeks total return  consistent  with  investment in
U.S. Treasury inflation-adjusted securities.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys  inflation-indexed  U.S.  Treasury  securities  guaranteed  by the
direct   full  faith  and   credit   pledge  of  the  U.S.   government.   These
inflation-indexed securities are designed to protect the future purchasing power
of the money invested in them.

The fund also may buy U.S. Treasury  securities that are not  inflation-indexed.
The fund may invest up to 35% of its total assets in these securities.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Inflation-adjusted  securities  are sold  based  upon an  assumption  about real
interest rates.  "Real" interest rates are the market rate of interest minus the
anticipated rate of inflation.  Changes in real interest rates affect the amount
of income the fund  generates.  Generally,  when real interest  rates rise,  the
fund's  share  value will  decline.  The  opposite is true when  interest  rates
decline. This real interest rate risk is higher for Inflation-Adjusted  Treasury
than for funds that do not invest in inflation-indexed securities.

As  with  all  funds,   at  any  given  time,   the  value  of  your  shares  of
Inflation-Adjusted  Treasury  may be worth more or less than the price you paid.
If you sell your shares when the value is less than the price you paid, you will
lose money.







SHORT-TERM GOVERNMENT FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Short-Term  Government  seeks high current  income while  maintaining  safety of
principal.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys short-term securities issued by the U.S. government,  its agencies
and instrumentalities, including mortgage-backed securities. The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.  The fund also may buy short-term  U.S.  Treasury  securities
guaranteed by the direct full faith and credit pledge of the U.S. government.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

The weighted average maturity of the fund is expected to be three years or less.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Interest rate changes affect the amount of income the fund generates. Generally,
when interest rates rise,  the fund's share value will decline.  The opposite is
true when  interest  rates  decline.  This  interest  rate  risk is  higher  for
Short-Term  Government  than  for  funds  that  have  shorter  weighted  average
maturities, such as money market funds.

Short-Term  Government  invests in mortgage-backed  securities.  When homeowners
refinance their mortgages to take advantage of declining  interest rates,  their
existing  mortgages  are  prepaid.  The  mortgages,  which  back the  securities
purchased by Short-Term Government,  may be prepaid in this fashion.  Because of
this "prepayment  risk," the fund may benefit less from declining interest rates
than other short-term funds.

As with all  funds,  at any given  time the value of your  shares of  Short-Term
Government  may be worth more or less than the price you paid.  If you sell your
shares when the value is less than the price you paid, you will lose money.







GNMA FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

Short-Term  Government  seeks high current  income while  maintaining  safety of
principal.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund buys short-term securities issued by the U.S. government,  its agencies
and instrumentalities, including mortgage-backed securities. The U.S. government
provides   varying   levels  of   financial   support  to  these   agencies  and
instrumentalities.  The fund also may buy short-term  U.S.  Treasury  securities
guaranteed by the direct full faith and credit pledge of the U.S. government.

The fund may purchase  securities  in a number of different  ways to seek higher
rates of return.  For  example,  by using  when-issued  and  forward  commitment
transactions, the fund may purchase securities in advance to generate additional
income.

The weighted average maturity of the fund is expected to be three years or less.

WHAT ARE THE PRIMARY RISKS OF INVESTING IN THE FUND?

Interest rate changes affect the amount of income the fund generates. Generally,
when interest rates rise,  the fund's share value will decline.  The opposite is
true when  interest  rates  decline.  This  interest  rate  risk is  higher  for
Short-Term  Government  than  for  funds  that  have  shorter  weighted  average
maturities, such as money market funds.

Short-Term  Government  invests in mortgage-backed  securities.  When homeowners
refinance their mortgages to take advantage of declining  interest rates,  their
existing  mortgages  are  prepaid.  The  mortgages,  which  back the  securities
purchased by Short-Term Government,  may be prepaid in this fashion.  Because of
this "prepayment  risk," the fund may benefit less from declining interest rates
than other short-term funds.

As with all  funds,  at any given  time the value of your  shares of  Short-Term
Government  may be worth more or less than the price you paid.  If you sell your
shares when the value is less than the price you paid, you will lose money.








BASICS OF FIXED INCOME INVESTING

DEBT SECURITIES

When a fund buys a debt security,  which is also called a fixed-income security,
it is  essentially  lending money to the issuer of the security.  Notes,  bonds,
commercial paper and Treasury bills are examples of debt  securities.  After the
issuer  first  sells  the  debt  security,  it may be  bought  and sold by other
investors.  The price of the  security  may rise or fall based on many  factors,
including changes in interest rates, inflation and liquidity.

The fund managers decide which debt securities to buy and sell by

>>   determining which securities help a fund meet its maturity requirements

>>   identifying securities that satisfy a fund's credit quality requirements

>>   evaluating  the  current  economic  conditions  and  assessing  the risk of
     inflation

>>   evaluating  special  features of the securities  that may make them more or
     less attractive

WEIGHTED AVERAGE MATURITY

Like most loans,  debt  securities  eventually must be repaid (or refinanced) at
some date.  This date is called the maturity  date. The number of days left to a
debt  security's  maturity date is called the remaining  maturity.  The longer a
debt  security's  remaining  maturity,  the more  sensitive  it is to changes in
interest rates.

Because a bond fund will own many debt securities,  the fund managers  calculate
the average of the remaining  maturities of all of the debt  securities the fund
owns to evaluate the interest rate  sensitivity  of the entire  portfolio.  This
average is weighted according to the size of the fund's individual  holdings and
is called  WEIGHTED  AVERAGE  MATURITY.  The  following  chart  shows how a fund
manager would calculate the weighted average maturity for a fund that owned only
two debt securities.

TYPES OF RISK

The basic types of risk that the funds face are described below.

INTEREST RATE RISK

Generally,  interest  rates and the prices of debt  securities  move in opposite
directions.  So when  interest  rates fall,  the prices of most debt  securities
rise; when interest rates rise, prices fall.  Because the funds invest primarily
in  debt   securities,   changes  in  interest  rates  will  affect  the  funds'
performance.

The degree to which interest rate changes affect the funds'  performance  varies
and is related to the weighted average maturity of each fund. For example,  when
interest  rates rise, you can expect the share value of a long-term bond fund to
fall more than that of a short-term  bond fund. When rates fall, the opposite is
true.
This sensitivity to interest rate changes is called interest rate risk.

***********LEFT MARGIN CALLOUTS

WEIGHTED  AVERAGE  MATURITY is a tool that the fund managers use to  approximate
the remaining maturity of a fund's investment portfolio.

o    The longer a fund's weighted average maturity,  the more sensitive it is to
     changes in interest rates.

***********END LEFT MARGIN CALLOUTS

When interest rates change, longer maturity bonds experience a greater change in
price.  The following  table shows the effect of a 1% increase in interest rates
on the price of 7% coupon bonds of differing maturities:

</TABLE>

CREDIT RISK

Credit risk is the risk that an obligation won't be paid and a loss will result.
A high  credit  rating  indicates  a high  degree of  confidence  by the  rating
organization  that  the  issuer  will  be able to  withstand  adverse  business,
financial or economic  conditions  and be able to make  interest  and  principal
payments on time.  Generally,  a lower credit rating indicates a greater risk of
non-payment.  A lower rating also may indicate that the issuer has a more senior
series of debt  securities,  which  means that if the  issuer  has  difficulties
making  its  payments,  the  more  senior  series  of debt is  first in line for
payment.

It's not as simple as buying the  highest-rated  debt securities.  Higher credit
ratings   usually  mean  lower  interest  rates,  so  investors  often  purchase
securities that aren't the highest rated to increase return. If a fund purchases
lower-rated securities, it assumes additional credit risk.

While U.S.  government  securities are not rated, they are generally regarded as
having the equivalent of the highest credit quality available. Because the funds
offered by this Prospectus invest in government securities,  they are considered
to have very low credit risk.

LIQUIDITY RISK

Debt securities can become  difficult to sell for a variety of reasons,  such as
lack of an active trading market.  When a fund's investments become difficult to
sell, it is said to have a problem with  liquidity.  The chance that a fund will
have liquidity issues is called liquidity risk.

INFLATION RISK

The safest investments usually have the lowest potential income and performance.
There  is  a  risk,   then,  that  returns  from  the  investment  may  fail  to
significantly  outpace  inflation.  Even if the value of your investment has not
gone  down,  your  money  will  not be  worth  as much as if  there  had been no
inflation.  Your after-inflation  return may be quite small. This risk is called
inflation risk.

The funds  engage in a variety of  investment  techniques  as they pursue  their
investment objectives. Each technique has its own characteristics,  and may pose
some  level of risk to the funds.  If you would  like to learn more about  these
techniques,  you should review the Statement of  Additional  Information  before
making an investment.








MANAGEMENT

WHO MANAGES THE FUNDS?

The Board of  Trustees,  investment  advisor and fund  management  team play key
roles in the management of the funds.

THE BOARD OF TRUSTEES

The Board of Trustees  oversees the  management  of the funds and meets at least
quarterly  to  review  reports  about  fund  operations.  Although  the Board of
Trustees does not manage the funds, it has hired an investment advisor to do so.
More than half of the trustees are independent of the funds'  advisor,  that is,
they are not employed by and have no financial interest in the advisor.

THE INVESTMENT ADVISOR

The funds' investment  advisor is American Century Investment  Management,  Inc.
The advisor has been  managing  mutual  funds  since 1958.  American  Century is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible  for managing the investment  portfolios of the funds
and directing the purchase and sale of their investment securities.  The advisor
also arranges for transfer agency,  custody and all other services necessary for
the funds to operate.

For the services it provided to the funds during their most recent  fiscal year,
the  advisor  received a unified  management  fee based on a  percentage  of the
average net assets of the Advisor Class of shares of each fund.  The rate of the
management fee for a fund is determined on a class-by-class  basis monthly using
a two-step  formula that takes into account the fund's  strategy  (money market,
bond or equity) and the total amount of mutual fund assets the advisor manages.

The Statement of Additional  Information contains detailed information about the
calculation  of the  management  fee.  Out of that  fee,  the  advisor  paid all
expenses of managing and operating the fund except  brokerage  expenses,  taxes,
interest,  fees and  expenses  of the  independent  directors  (including  legal
counsel fees) and extraordinary expenses.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio  managers,  assistant portfolio managers and
analysts to manage the funds.  Teams meet regularly to review portfolio holdings
and to discuss purchase and sale activity.  Team members buy and sell securities
for a fund as they  see fit,  guided  by the  fund's  investment  objective  and
strategy.

The portfolio managers who lead each team are identified below:

o    CODE OF ETHICS
     American Century has a Code of Ethics designed to ensure that the interests
     of fund shareholders come before the interests of the people who manage the
     funds.  Among  other  provisions,  the Code of Ethics  prohibits  portfolio
     managers  and other  investment  personnel  from  buying  securities  in an
     initial public offering or from profiting from the purchase and sale of the
     same  security  within 60 calendar  days.  In addition,  the Code of Ethics
     requires  portfolio managers and other employees with access to information
     about the purchase or sale of  securities  by the funds to obtain  approval
     before executing permitted personal trades.

FUNDAMENTAL INVESTMENT POLICIES

Fundamental  investment  policies  contained  in  the  Statement  of  Additional
Information  and the  investment  objectives  of the  funds  may not be  changed
without a shareholder  vote. The Board of Trustees may change any other policies
and investment strategies.

YEAR 2000 ISSUES

Many of the world's  computer  systems were originally  programmed in a way that
prevented   them  from  properly   recognizing   or  processing   date-sensitive
information  relating to the Year 2000 and beyond.  Because  this may impact the
computer  systems of various  American  Century-affiliated  and external service
providers  for the  funds,  American  Century  formally  initiated  a Year  2000
readiness  project in July 1997.  It involves a team of  information  technology
professionals  assisted  by outside  consultants  and  guided by a  senior-level
steering committee.  The team's goal is to assess the impact of the Year 2000 on
American Century's systems,  renovate or replace  noncompliant  critical systems
and test  those  systems.  In  addition,  the team has been  working  to  gather
information  about the Year 2000  efforts  of the  funds'  other  major  service
providers.

Although  American Century believes its critical systems will function  properly
in the Year 2000, this is not guaranteed.  If the efforts of American Century or
its  external  service  providers  are  not  successful,  the  funds'  business,
particularly the provision of shareholder services, may be hampered.

In  addition,  the  issuers  of  securities  the funds own could  have Year 2000
computer  problems.  These problems could  negatively  affect the value of their
securities, which, in turn, could impact the funds' performance. The advisor has
established a process to gather publicly  available  information  about the Year
2000  readiness  of these  issuers.  However,  this  process may not uncover all
relevant  information,  and the  information  gathered  may not be complete  and
accurate.  Moreover, an issuer's Year 2000 readiness is only one of many factors
the fund  managers  may consider  when making  investment  decisions,  and other
factors may receive greater weight.






INVESTING WITH AMERICAN CENTURY
ELIGIBILITY FOR ADVISOR CLASS SHARES
The  Advisor  Class  shares  are  intended  for  purchase  by   participants  in
employer-sponsored retirement or savings plans and for persons purchasing shares
through   broker-dealers,   banks,   insurance  companies  and  other  financial
intermediaries that provide various administrative and distribution services.

INVESTING THROUGH FINANCIAL INTERMEDIARIES
If you do business  with us through a  financial  intermediary  or a  retirement
plan,  your ability to purchase,  exchange and redeem  shares will depend on the
policies of that entity. Some policy differences may include

minimum investment requirements
exchange policies
fund choices
cutoff time for investments

Please  contact  your  financial  intermediary  or plan  sponsor  for a complete
description  of its policies.  Copies of the funds' annual  reports,  semiannual
reports  and  Statements  of  Additional  Information  are  available  from your
intermediary or plan sponsor.

Certain  financial   intermediaries  perform  recordkeeping  and  administrative
services  for their  clients  that would  otherwise  be  performed  by  American
Century's transfer agent. In some  circumstances,  American Century will pay the
service provider a fee for performing those services.

Although  transactions in fund shares may be made directly with American Century
at no charge,  you also may purchase,  redeem and exchange  fund shares  through
financial  intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

American Century has contracts with certain financial  intermediaries  requiring
them to track  the time  investment  orders  are  received  and to  comply  with
procedures  relating to the  transmission  of orders.  The funds has  authorized
those  intermediaries to accept orders on its behalf up to the time at which the
net asset  value is  determined.  If those  orders are  transmitted  to American
Century and paid for in accordance with the contract, they will be priced at the
net asset  value next  determined  after your  request is  received  in the form
required by the intermediary on a fund's behalf.

ABUSIVE TRADING PRACTICES
We do not permit market timing or other abusive trading practices in our funds.

Excessive,  short-term  (market timing) or other abusive  trading  practices may
disrupt portfolio management  strategies and harm fund performance.  To minimize
harm to the funds and their  shareholders,  we  reserve  the right to reject any
purchase order (including  exchanges) from any investor we believe has a history
of  abusive  trading  or  whose  trading,  in our  judgment,  has been or may be
disruptive to a fund. In making this judgment,  we may consider  trading done in
multiple  accounts under common ownership or control.  We also reserve the right
to delay delivery of your  redemption  proceeds - up to seven days - or to honor
certain redemptions with securities,  rather than cash, as described in the next
section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS
If,  during any 90-day  period,  you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than  $250,000),  we
reserve  the right to pay part or all of the  redemption  proceeds  in excess of
this amount in readily marketable securities instead of cash. If we make payment
in securities,  we will value the securities,  selected by the fund, in the same
manner as we do in computing  the fund's net asset value.  We may provide  these
securities in lieu of cash without prior notice.

If your  redemption  would  exceed  this limit and you would like to avoid being
paid in  securities,  please  provide us with an  unconditional  instruction  to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur.  The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the  transaction.  This  minimizes the effect of the
redemption on the fund and its remaining shareholders.

SHARE PRICE AND DISTRIBUTIONS

SHARE PRICE

American Century  determines the NET ASSET VALUE of the funds as of the close of
regular  trading on the New York Stock  Exchange  (usually 4 p.m.  Eastern time)
each day the Exchange is open.  On days when the Exchange is not open, we do not
calculate  the net  asset  value.  The net  asset  value of a fund  share is the
current value of the fund's investments,  minus any liabilities,  divided by the
number of fund shares outstanding.

If current market prices of securities owned by a fund are not readily available
from an independent pricing service,  the advisor may determine their fair value
in accordance with procedures  adopted by the fund's Board of Trustees.  Trading
of securities in foreign markets may not take place on every day the Exchange is
open.  Also,  trading in some  foreign  markets  may take place on  weekends  or
holidays  when a fund's net asset  value is not  calculated.  So, the value of a
fund's  portfolio  may be  affected  on days when you can't  purchase  or redeem
shares of the fund.

We will price your purchase,  exchange or redemption at the net asset value next
determined after we receive your transaction request in good order.

It is the responsibility of your plan recordkeeper or financial  intermediary to
transmit your purchase,  exchange and redemption  requests to the funds transfer
agent prior to the  applicable  cut-off  time for  receiving  orders and to make
payment for any purchase  transactions in accordance with the funds'  procedures
or any  contractual  arrangements  with the funds or the funds'  distributor  in
order for you to receive that day's price.


DISTRIBUTIONS

Federal tax laws require each fund to make  distributions to its shareholders in
order  to  qualify  as a  "regulated  investment  company."  Qualification  as a
regulated investment company means that the fund will not be subject to state or
federal income tax on amounts distributed.  The distributions  generally consist
of dividends and interest  received,  as well as CAPITAL  GAINS  realized on the
sale of investment  securities.  Each money market fund  declares  distributions
from net income daily.  These  distributions are paid on the last Friday of each
month. Each of the other funds pays distributions from net income monthly.  Each
fund (except the money market funds)  generally  pays  distributions  of capital
gains,  if  any,  once  a year  in  December.  A fund  may  make  more  frequent
distributions if necessary to comply with Internal Revenue Code provisions.

You will begin to participate in fund  distributions the day after your purchase
is effective.  If you redeem shares, you will receive the distribution  declared
for  the day  you  redeem.  If you  redeem  all  shares,  we  will  include  the
distributions on the redeemed with your redemption proceeds.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions.  For shareholders  investing  through taxable  accounts,  we will
reinvest  distributions unless you elect to receive them in cash. Please consult
our Investor Services Guide for further information regarding  distributions and
your distribution options.

**********LEFT MARGIN CALLOUTS

The NET ASSET VALUE of a fund is the price of the fund's shares.

CAPITAL GAINS are increases in the values of capital assets, such as stock, from
the time the assets are  purchased.  Tax  becomes  due on capital  gains once an
asset is sold.

**********END LEFT MARGIN CALLOUTS






TAXES

The tax  consequences  of  owning  shares of the funds  will vary  depending  on
whether you own them through a taxable or tax-deferred account. Tax consequences
result from distributions by the funds of dividend and interest income they have
received  and  capital  gains  they  have  generated  through  their  investment
activities.  Tax consequences also result from sales of fund shares by investors
after the net asset value has increased or decreased.

TAX-DEFERRED ACCOUNTS

If you purchase fund shares through a tax-deferred  account, such as an IRA or a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  usually will not be subject to current taxation,  but will
accumulate in your account  under the plan on a  tax-deferred  basis.  Likewise,
moving  from one fund to  another  fund  within a plan or  tax-deferred  account
generally  will  not  cause  you to be  taxed.  For  information  about  the tax
consequences of making  purchases or withdrawals  through an  employer-sponsored
retirement  or  savings  plan,  or  through  an IRA,  please  consult  your plan
administrator, your summary plan description or a professional tax advisor.

TAXABLE ACCOUNTS

If you own fund shares through a taxable account,  distributions by the fund and
sales by you of fund shares may cause you to be taxed.

TAXABILITY OF DISTRIBUTIONS

Fund distributions may consist of income earned by the fund from sources such as
dividends  and  interest,  or  capital  gains  generated  from  the sale of fund
investments. Distributions of income are taxed as ordinary income. Distributions
of capital gains are classified  either as short-term or long-term and are taxed
as follows:


<TABLE>
Type of distribution          Tax rate for 15% bracket       Tax rate for 28% bracket or above
- --------------------------- ----------------------------- -----------------------------------------
<S>                                      <C>                                <C>
Short-term capital gains        Ordinary income rate                Ordinary income rate
Long-term capital gains                  10%                                20%
</TABLE>

The tax status of any  distribution  of capital  gains is determined by how long
the fund held the  underlying  security that was sold,  not by how long you have
been  invested  in the  fund or  whether  you  reinvest  your  distributions  in
additional  shares or take them as income.  American Century will detail the tax
status of fund  distributions  for each  calendar  year in an annual tax mailing
(Form 1099) from the fund.

Distributions may also be subject to state and local taxes.  Because  everyone's
tax situation is unique,  always  consult your tax  professional  about federal,
state and local tax consequences.

TAXES ON TRANSACTIONS

Your  redemptions -- including  exchanges to other American Century funds -- are
subject to capital  gains tax.  The table above can provide a general  guide for
your potential tax liability when selling or exchanging fund shares.  Short-term
capital  gains are gains on fund  shares  held for 12 months or less.  Long-term
capital  gains are gains on fund  shares  held for more than 12 months.  If your
shares  decrease in value,  their sale or exchange will result in a long-term or
short-term  capital loss.  However,  you should note that any loss realized upon
the sale or  redemption of shares held for six months or less will be treated as
a long-term  capital loss to the extent of any distribution of long-term capital
gain to you with respect to such shares. If a loss is realized on the redemption
of fund shares, the reinvestment in additional fund shares within 30 days before
or after the  redemption  may be subject to the wash sale rules of the  Internal
Revenue Code,  resulting in a postponement  of the  recognition of such loss for
federal  income tax  purposes.  If you have not certified to us that your social
security  number or tax  identification  number is correct  and that you are not
subject to 31% withholding, we are required to withhold and remit to the IRS 31%
of dividends, capital gains distributions and redemptions.

**********LEFT MARGIN CALLOUTS

o    BUYING A DIVIDEND
     Purchasing  fund shares in a taxable  account shortly before a distribution
     is sometimes known as buying a dividend. In taxable accounts,  you must pay
     income taxes on the  distribution  whether you reinvest the distribution or
     take  it in  cash.  In  addition,  you  will  have  to  pay  taxes  on  the
     distribution whether the value of your investment  decreased,  increased or
     remained the same after you bought the fund shares.

     The risk in  buying a  dividend  is that a fund's  portfolio  may  build up
     taxable  gains  throughout  the  period  covered  by  a  distribution,   as
     securities  are sold at a profit.  We distribute  those gains to you, after
     subtracting  any losses,  even if you did not own the shares when the gains
     occurred.

     If you buy a dividend, you incur the full tax liability of the distribution
     period, but you may not enjoy the full benefit of the gains realized in the
     fund's portfolio.

MULTIPLE CLASS INFORMATION

American  Century  offers two  classes of the fund:  Investor  Class and Advisor
Class.  The shares  offered by this  Prospectus are Advisor Class shares and are
offered primarily to institutional investors through institutional  distribution
channels,  such  as  employer-sponsored  retirement  plans,  or  through  banks,
broker-dealers and insurance companies.

American Century offers another class of shares that has no up-front or deferred
charges, commissions or 12b-1 fees. The other class has different fees, expenses
and/or minimum  investment  requirements than the Investor Class. The difference
in the fee  structures  between  the  classes  is the  result of their  separate
arrangements for shareholder and distribution services and not the result of any
difference  in  amounts  charged by the  advisor  for core  investment  advisory
services.  Accordingly,  the core  investment  advisory  expenses do not vary by
class.  Different  fees and expenses  will affect  performance.  For  additional
information  concerning  the  other  classes  of  shares  not  offered  by  this
Prospectus,  call us at 1-800-345-2021  for Investor Class shares.  You also can
contact a sales  representative or financial  intermediary who offers that class
of shares.

Except as  described  below,  all  classes of shares of the fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only differences  between the classes are (a) each class may be
subject to  different  expenses  specific  to that  class;  (b) each class has a
different  identifying  designation or name; (c) each class has exclusive voting
rights with respect to matters solely  affecting such class;  and (d) each class
may have different exchange privileges.


SERVICE AND DISTRIBUTION FEES
Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay out of fund assets certain  expenses  associated with the distribution of
their shares. The funds' Advisor Class shares have a 12b-1 Plan. Under the Plan,
the  fund  pays  an  annual  fee of  0.50%  of fund  assets,  half  for  certain
shareholder and administrative  services and half for distribution services. The
advisor,  as paying  agent for the funds,  pays all or a portion of such fees to
the  banks,  broker-dealers  and  insurance  companies  that  make  such  shares
available.  Because  these fees are paid out of the fund's assets on an on-going
basis,  over time these fees will increase the cost of your  investment  and may
cost  you  more  than  paying  other  types of  sales  charges.  For  additional
information about the Plan and its terms, see "Multiple Class Structure - Master
Distribution  and  Shareholder  Services  Plan" in the  Statement of  Additional
Information.





Financial Highlights

UNDERSTANDING THE FINANCIAL HIGHLIGHTS

The tables on the next few pages  itemize  what  contributed  to the  changes in
share  price  during the  period.  They also show the changes in share price for
this period in  comparison  to changes over the last five fiscal years (or less,
if the share class is not five years old).

On a per-share basis, each table includes:

o    share price at the beginning of the period

o    investment income and capital gains or losses

o    distributions of income and capital gains paid to shareholders

o    share price at the end of the period

Each table also includes some key statistics for the period:

o    Total Return--the  overall  percentage of return of the fund,  assuming the
     reinvestment of all distributions

o    Expense Ratio--operating expenses as a percentage of average net assets

o    Net Income  Ratio--net  investment  income as a  percentage  of average net
     assets

o    Portfolio  Turnover--the  percentage  of  the  fund's  buying  and  selling
     activity

The Financial Highlights for the fiscal years ended March 31, 1998 and 1999 have
been audited by  PricewaterhouseCoopers,  LLP,  independent  accountants.  Their
report is included  in the funds'  annual  reports,  which are  incorporated  by
reference into the Statement of Additional  Information,  and are available upon
request.  Prior years'  information was audited by other  independent  auditors,
whose report also is  incorporated by reference into the Statement of Additional
Information.

PERFORMANCE INFORMATION OF THE OTHER CLASS
The following  financial  information is provided to show the performance of the
funds' original class of shares.  This class,  the Investor  Class,  has a total
expense ratio that is 0.25% lower than the Advisor  Class.  If the Advisor Class
existed  during the periods  presented,  its  performance  would have been lower
because of the additional expense.

The tables  itemize  what  contributed  to the changes in share price during the
period.  They also show the changes in share price for this period in comparison
to changes over the last five fiscal  years (or less,  if the share class is not
five years old).

On a per-share basis, each table includes:

o    share price at the beginning of the period
o    investment income and capital gains or losses
o    distributions of income and capital gains paid to shareholders
o    share price at the end of the period

Each table also includes some key statistics for the period:

o    total return--the  overall  percentage of return of the fund,  assuming the
     reinvestment of all distributions

o    expense ratio--operating expenses as a percentage of average net assets

o    net income  ratio--net  investment  income as a  percentage  of average net
     assets

o    portfolio  turnover--the  percentage  of  the  fund's  buying  and  selling
     activity



The Financial Highlights for the fiscal years ended March 31, 1998 and 1999 have
been  audited by  PricewaterhouseCoopers  LLP,  independent  accountants.  Their
report is included  in the funds'  annual  reports,  which are  incorporated  by
reference into the Statement of Additional  Information,  and are available upon
request.  Prior years'  information was audited by other  independent  auditors,
whose report also is  incorporated by reference into the Statement of Additional
Information.

Prospectus.

Each  fund is a  diversified  open-end  investment  company  as  defined  in the
Investment Company Act of 1940 (the Investment  Company Act).  Diversified means
that,  with respect to 75% of its total  assets,  each fund will not invest more
than 5% of its total assets in the securities of a single issuer.

The fund operates  pursuant to Rule 2a-7 under the Investment  Company Act. That
rule permits the  valuation of  portfolio  securities  on the basis of amortized
cost. To rely on the rule, each fund must be diversified  with regard to 100% of
its assets other than U.S. government securities.  This operating policy is more
restrictive  than the  Investment  Company  Act,  which  requires a  diversified
investment company to be diversified with regard to only 75% of its assets.

To meet federal tax  requirements for  qualification  as a regulated  investment
company,  each fund  must  limit  its  investments  so that at the close of each
quarter  of its  taxable  year (1) no more  than  25% of its  total  assets  are
invested in the  securities of a single issuer (other than the U.S government or
a regulated  investment  company),  and (2) with  respect to at least 50% of its
total assets, no more than 5% of its total assets are invested in the securities
of a single issuer.

Each fund (except  Short-Term  Government and the GNMA Fund) seeks income exempt
from state taxes by  investing  in U.S.  government  securities  whose  interest
payments are state tax-exempt.  As a result, these funds' dividend distributions
are  expected  to be  exempt  from  state  income  tax.  See  page  29 for  more
information on tax treatment of the funds' distributions.


THE MONEY MARKET FUNDS
Each of the money market  funds seeks to maintain a $1.00 share price,  although
there is no  guarantee  they will be able to do so.  Shares of the money  market
funds are neither insured nor guaranteed by the U.S. government.


Capital Preservation
Capital Preservation seeks maximum safety and liquidity. Its secondary objective
is to seek  to pay  its  shareholders  the  highest  rate  of  return  on  their
investment in Capital Preservation consistent with safety and liquidity. Capital
Preservation  pursues its  investment  objectives  by investing  exclusively  in
short-term  U.S.  Treasury  securities  guaranteed  by the direct full faith and
credit pledge of the U.S.  government.  Capital  Preservation's  dollar-weighted
average portfolio maturity will not exceed 90 days.

While the risks associated with investing in short-term U.S. Treasury securities
are very low, an investment in Capital Preservation is not risk-free.


Government Agency
Government  Agency  seeks to provide the highest  rate of current  return on its
investments,  consistent  with safety of principal and maintenance of liquidity,
by investing  exclusively in short-term  obligations of the U.S.  government and
its agencies and  instrumentalities,  the income from which is exempt from state
taxes.  Under  normal  conditions,  at least 65% of the fund's  total assets are
invested in  securities  issued by agencies  and  instrumentalities  of the U.S.
government.  Assets  not  invested  in these  securities  are  invested  in U.S.
Treasury securities. For temporary defensive purposes, the fund may invest up to
100% of its assets in U.S.  Treasury  securities.  The fund's  weighted  average
portfolio maturity will not exceed 90 days.

The U.S. government provides varying levels of financial support to its agencies
and instrumentalities.


THE U.S. TREASURY FUNDS

Short-Term Treasury, Intermediate-Term Treasury, Long-Term Treasury
Short-Term Treasury, Intermediate-Term Treasury and Long-Term Treasury are quite
similar  to one  another  but can be  differentiated  by  their  dollar-weighted
average maturities.  Among these funds, the longer its  dollar-weighted  average
maturity, the more its share price will fluctuate when interest rates change.

This  pattern is due,  in part,  to the time value of money.  A bond's  worth is
determined in part by the present value of its future cash flows.  Consequently,
changing  interest  rates  have a  greater  effect  on the  present  value  of a
long-term bond than a short-term bond.  Because of this interplay between market
interest  rates and share  price,  investors  are  encouraged  to evaluate  fund
performance on the basis of total return.

The investment objectives of the funds are as follows: Short-Term Treasury seeks
to earn and  distribute  the highest  level of current  income exempt from state
income taxes as is consistent with  preservation  of capital.  Intermediate-Term
Treasury  seeks to earn and  distribute  the  highest  level of  current  income
consistent  with the  conservation  of assets  and the safety  provided  by U.S.
Treasury  bills,  notes  and  bonds.  Long-Term  Treasury  seeks  to  provide  a
consistent and high level of current income exempt from state taxes.

Short-Term,  Intermediate-Term  and Long-Term  Treasury pursue their  investment
objectives by investing primarily in securities issued or guaranteed by the U.S.
Treasury. As a result, each fund may invest in U.S. Treasury bills, bonds, notes
and  zero-coupon  securities,  all of which are also  backed by the direct  full
faith and  credit  pledge of the U.S.  government.  In  addition,  the funds may
invest up to 35% of their total  assets in  securities  issued by  agencies  and
instrumentalities of the U.S. government.

Within this  framework,  the funds differ in the  remaining  maturities of their
portfolio securities and the dollar-weighted average maturities of their overall
portfolio.  Under normal conditions,  the funds' maturity characteristics are as
follows:  Short-Term  Treasury  invests  primarily in securities  with remaining
maturities  of 3 years or less,  and  maintains  a  weighted  average  portfolio
maturity  ranging  from 13 months to three years.  Intermediate-Term  Treasury's
weighted  average  portfolio  maturity ranges from three to 10 years.  Long-Term
Treasury invests primarily in securities with maturities of 10 or more years and
maintains a weighted average portfolio maturity ranging from 20 to 30 years.

Each of the funds is  designed to allow  investors  to seek  competitive  yields
within their tolerance for share price fluctuations.  Thus,  Short-Term Treasury
may be  appropriate  for investors who are seeking  higher  current  yields than
those  available  from money market funds and who can tolerate  some share price
volatility.  Similarly,  the current yield for  Intermediate-Term  Treasury will
likely  be  higher  than  that  of  Short-Term  Treasury,  but the  share  price
volatility will be greater.  By maintaining an average portfolio  maturity of 20
to 30 years,  Long-Term  Treasury offers  investors the potential to earn higher
current  yields than those  typically  available  from  Short-Term  Treasury and
Intermediate-Term Treasury.  Long-Term Treasury may also offer greater potential
for  capital  appreciation.  However,  maintaining  a  relatively  long  average
maturity also means that the Long-Term  Treasury's share price generally will be
the most volatile of the three funds.


Inflation-Adjusted Treasury
Inflation-Adjusted Treasury pursues its investment objective by investing, under
normal market conditions,  at least 65% of its total assets in inflation-indexed
Treasury  securities  that are  backed by the full  faith and credit of the U.S.
government and indexed or otherwise  structured by the U.S.  Treasury to provide
protection  against  inflation.  Inflation-indexed  Treasury  securities  may be
issued  by the U.S.  Treasury  in the form of notes or  bonds.  Up to 35% of the
fund's total assets may be invested in  inflation-indexed  securities  issued by
U.S.    government    agencies    and    government-sponsored     organizations.
Inflation-Adjusted Treasury also may invest in U.S. Treasury securities that are
not indexed to inflation for  liquidity and total return,  or if at any time the
fund   managers   believe  there  is  an   inadequate   supply  of   appropriate
inflation-indexed  securities  in which to invest or when such  investments  are
required  as  a  temporary  defensive  measure.   Inflation-Adjusted  Treasury's
portfolio may consist of any  combination of these  securities  consistent  with
investment strategies employed by the manager. While Inflation-Adjusted Treasury
seeks to provide a measure of inflation protection to its investors, there is no
assurance  that the  fund  will  provide  less  risk  than a fund  investing  in
conventional fixed-principal securities.

There are no maturity  or  duration  restrictions  for the  securities  in which
Inflation-Adjusted   Treasury   may  invest.   The  U.S.   Treasury  has  issued
inflation-indexed  Treasury  securities  with  five-year  and  10-year  terms to
maturity. It has announced its intention (although there is no guarantee it will
do so) to issue  additional  securities  with a term to  maturity  as long as 30
years.  The managers will buy from among the available  issues those  securities
that will provide the maximum relative value to the fund.

Inflation-Adjusted  Treasury may be appropriate for investors who are seeking to
protect  all or a part  of  their  investment  portfolio  from  the  effects  of
inflation.

Traditional U.S. Treasury fixed-principal notes and bonds pay a stated return or
rate of  interest in dollars  and are  redeemed  at their par amount.  Inflation
during the period that the securities are  outstanding  will diminish the future
purchasing  power of these dollars.  Inflation-Adjusted  Treasury is designed to
serve as a vehicle to protect against this diminishing effect.

Inflation-Adjusted  Treasury is designed to provide total return consistent with
an  investment  in  inflation-indexed  Treasury  securities.  Inflation-Adjusted
Treasury's  yield will reflect both the  inflation-adjusted  interest income and
the inflation  adjustment to principal  which are features of  inflation-indexed
Treasury securities. The current income generated by Inflation-Adjusted Treasury
will vary with month to month changes in the CPI index and may be  substantially
more or substantially less than traditional fixed-principal securities.

Inflation-indexed  securities  in which the fund may invest are  relatively  new
securities.  There  are  special  investment  risks,  particularly  share  price
volatility and potential adverse tax consequences, associated with investment in
inflation-indexed  securities.  These risks are described in the section  titled
"Risk Factors and Investment Techniques". You should read that section carefully
to make sure you understand the nature of Inflation-Adjusted Treasury before you
invest in it.


THE GOVERNMENT AGENCY FUNDS

Short-Term Government
Short-Term  Government  seeks to provide  investors with a high level of current
income,  consistent with stability of principal.  Short-Term  Government pursues
this objective by investing  primarily in securities issued or guaranteed by the
U.S. government or its agencies or  instrumentalities.  Under normal conditions,
the fund managers invest at least 65% of Short-Term Government's total assets in
securities of the U.S.  government  and its agencies and  maintaining a weighted
average duration of three years or less.


GNMA Fund
The GNMA Fund seeks to provide a high level of current  income  consistent  with
safety of principal  and  maintenance  of  liquidity  by investing  primarily in
mortgage-backed Ginnie Mae certificates.

Ginnie Mae  certificates  represent  interests in pools of mortgage loans and in
the cash flows from those loans.  These  certificates are guaranteed by GNMA and
backed by the full  faith and  credit of the U.S.  government  as to the  timely
payment of interest and repayment of  principal,  which means that the GNMA Fund
receives its share of interest and  principal  payments  owed on the  underlying
pool of mortgage  loans,  regardless of whether  borrowers make their  scheduled
mortgage payments.

Assets not  invested in Ginnie Mae  certificates,  directly or  indirectly,  are
invested  in  other  U.S.   government   securities  or  repurchase   agreements
collateralized by U.S. government securities.  For temporary defensive purposes,
the GNMA Fund may invest 100% of its assets in these securities.

A unique feature of mortgage-backed securities, such as Ginnie Mae certificates,
is that their  principal is scheduled to be paid back gradually for the duration
of the loan rather than in one lump sum at maturity. Investors (such as the GNMA
Fund) receive scheduled monthly payments of principal and interest, but they may
also receive unscheduled  prepayments of principal on the underlying  mortgages.
See "Mortgage-Backed Securities" on page 16 for a discussion of prepayment risk.


DETAILED INFORMATION ABOUT THE FUNDS

INVESTMENT STRATEGIES AND RISKS
This section  describes each of the investment  vehicles and strategies that the
fund  managers  can use in managing a fund's  assets.  It also details the risks
associated  with each,  because each  technique  contributes to a fund's overall
risk profile.

U.S. Government Securities
U.S.  Treasury  bills,  notes,  zero-coupon  bonds  and other  bonds are  direct
obligations  of the U.S.  Treasury,  which has never  failed to pay interest and
repay principal when due. Treasury bills have initial  maturities of one year or
less,  Treasury  notes  from two to 10 years,  and  Treasury  bonds more than 10
years.  Although U.S. Treasury securities carry little principal risk if held to
maturity,  the  prices of these  securities  (like all debt  securities)  change
between issuance and maturity in response to fluctuating market interest rates.

A number of U.S.  government  agencies  and  government-sponsored  organizations
issue debt  securities.  These  agencies  generally  are  created by Congress to
fulfill a specific  need,  such as  providing  credit to home buyers or farmers.
Among these  agencies are the Federal  Home Loan Banks,  the Federal Farm Credit
Banks,  the  Student  Loan  Marketing  Association  and the  Resolution  Funding
Corporation.

Some  agency  securities  are  backed by the full  faith and  credit of the U.S.
government,  and  some  are  guaranteed  only  by  the  issuing  agency.  Agency
securities  typically offer somewhat higher yields than U.S. Treasury securities
with similar maturities.  However,  these securities may involve greater risk of
default than securities backed by the U.S. Treasury.

Interest rates on agency  securities may be fixed for the term of the investment
(fixed-rate   agency   securities)   or  tied  to  prevailing   interest   rates
(floating-rate agency securities).  Interest rate resets on floating-rate agency
securities generally occur at intervals of one year or less, based on changes in
a predetermined interest rate index.

Floating-rate  agency  securities  frequently  have caps  limiting the extent to
which coupon rates can be raised.  The price of a floating-rate  agency security
may decline if its capped coupon rate is lower than  prevailing  market interest
rates. Fixed- and floating-rate agency securities may be issued with a call date
(which permits  redemption before the maturity date). The exercise of a call may
reduce an obligation's yield to maturity. Capital Preservation may not invest in
floating-rate agency securities.

o        Interest Rate Resets on Floating-Rate U.S. Government Agency Securities
         (All Funds Except Capital  Preservation)  
Interest  rate  resets  on  floating-rate  U.S.   government  agency  securities
generally  occur at  intervals  of one year or less in  response to changes in a
predetermined  interest  rate index.  There are two main  categories of indices,
those based on U.S.  Treasury  securities  and those  derived  from a calculated
measure,  such as a cost of funds  index.  Commonly  used  indices  include  the
three-month,  six-month,  and one-year Treasury bill rate; the two-year Treasury
note yield;  the  Eleventh  District  Federal Home Loan Bank Cost of Funds Index
(EDCOFI);  and the London  Interbank  Offered Rate (LIBOR).  Fluctuations in the
prices  of  floating-rate  U.S.   government  agency  securities  are  typically
attributed  to  differences  between the coupon  rates on these  securities  and
prevailing market interest rates between interest rate reset dates.

o        Master Demand Notes (Government Agency Only)
Government Agency may acquire  variable-rate  master demand notes issued by U.S.
government  agencies  such as the Student  Loan  Marketing  Association.  Master
demand  notes allow the fund to lend money at varying  rates of  interest  under
direct agreements with borrowers. The fund may adjust the amount of money loaned
under a master  demand note daily or weekly up to the full amount  specified  in
the  agreement,  and the  borrower  may prepay up to the full amount of the loan
without penalty. Master demand notes may or may not be backed by bank letters of
credit.  Although, as direct agreements between lenders and borrowers,  there is
no secondary  market for master demand notes,  these  instruments are redeemable
(immediately  repayable by the  borrower)  at par plus  accrued  interest at any
time.

o        Zero-Coupon   Securities   (Short-Term   Treasury,    Intermediate-Term
         Treasury, Long-Term Treasury and Inflation-Adjusted Treasury)
Zero-coupon  U.S.  Treasury  securities are the unmatured  interest  coupons and
underlying  principal  portions of U.S.  Treasury  notes and bonds.  Originally,
these  securities were created by  broker-dealers  who bought Treasury notes and
bonds and deposited these  securities with a custodian bank. The  broker-dealers
then sold receipts representing  ownership interests in the coupons or principal
portions of the notes and bonds.  Some examples of zero-coupon  securities  sold
through custodial receipt programs are CATS (Certificates of Accrual on Treasury
Securities),  TIGRs  (Treasury  Investment  Growth  Receipts)  and  generic  TRs
(Treasury Receipts).

The U.S. Treasury  subsequently  introduced a program called Separate Trading of
Registered  Interest and  Principal of  Securities  (STRIPS).  In this  program,
eligible  securities  may be presented to the U.S.  Treasury and  exchanged  for
their component  parts,  which are then traded in book-entry  form.  (Book-entry
trading eliminated the bank credit risks associated with broker-dealer sponsored
custodial  receipt   programs.)  STRIPS  are  direct  obligations  of  the  U.S.
government and have the same credit risks as other U.S. Treasury securities.

Principal  and interest on bonds issued by the  Resolution  Funding  Corporation
(REFCORP) have also been separated and issued as stripped  securities.  The U.S.
government  and its agencies may issue  securities in  zero-coupon  form.  These
securities are referred to as original issue zero-coupon securities.


Mortgage-Backed Securities

o        Background
A  mortgage-backed  security  represents  an  ownership  interest  in a pool  of
mortgage loans. The loans are made by financial institutions to finance home and
other real estate purchases. As the loans are repaid, investors receive payments
of both interest and principal.

Like  fixed-income  securities  such as  U.S.  Treasury  bonds,  mortgage-backed
securities  pay a stated  rate of  interest  during  the  life of the  security.
However,  unlike a bond, which returns principal to the investor in one lump sum
at  maturity,  mortgage-backed  securities  return  principal to the investor in
increments during the life of the security.

Because  the timing and speed of  principal  repayments  vary,  the cash flow on
mortgage  securities  is  irregular.  If  mortgage  holders  sell  their  homes,
refinance  their loans,  prepay their  mortgages or default on their loans,  the
principal is distributed pro rata to investors.

As with  other  fixed-income  securities,  the  prices  of  mortgage  securities
fluctuate in response to changing  interest rates; when interest rates fall, the
prices of mortgage securities rise, and vice versa. Changing interest rates have
additional  significance  for  mortgage-backed  securities  investors,  however,
because they influence  prepayment  rates (the rates at which  mortgage  holders
prepay  their  mortgages),  which in turn  affect the yields on  mortgage-backed
securities.  When interest rates decline,  prepayment rates generally  increase.
Mortgage  holders take advantage of the opportunity to refinance their mortgages
at lower rates with lower monthly payments.  When interest rates rise,  mortgage
holders are less inclined to refinance their mortgages. The effect of prepayment
activity on yield depends on whether the mortgage-backed  security was purchased
at a premium or at a discount.

A fund may get back  principal  sooner than it expected  because of  accelerated
prepayments. Under these circumstances, the fund might have to reinvest returned
principal  at rates lower than it would have earned if principal  payments  were
made  on  schedule.  Conversely,  a  mortgage-backed  security  may  exceed  its
anticipated  life if  prepayment  rates  decelerate  unexpectedly.  Under  these
circumstances,  a fund  might miss an  opportunity  to earn  interest  at higher
prevailing rates.

o        Ginnie Mae Certificates
The Government  National  Mortgage  Association (GNMA or Ginnie Mae) is a wholly
owned  corporate  instrumentality  of the United States within the Department of
Housing and Urban  Development.  The National Housing Act of 1934 (Housing Act),
as amended,  authorizes  Ginnie Mae to guarantee the timely  payment of interest
and repayment of principal on certificates that are backed by a pool of mortgage
loans insured by the Federal Housing Administration under the Housing Act, or by
Title V of the Housing Act of 1949 (FHA Loans),  or  guaranteed by the Veterans'
Affairs under the Servicemen's  Readjustment Act of 1944 (VA Loans), as amended,
or by pools of other eligible  mortgage loans. The Housing Act provides that the
full faith and credit of the U.S.  government  is pledged to the  payment of all
amounts  that may be  required  to be paid under any  guarantee.  Ginnie Mae has
unlimited  authority  to  borrow  from  the U.S.  Treasury  in order to meet its
obligations under this guarantee.

Ginnie Mae  certificates  represent a pro rata  interest in one or more pools of
the following types of mortgage  loans:  (a) fixed-rate  level payment  mortgage
loans; (b) fixed-rate  graduated  payment mortgage loans (GPMs);  (c) fixed-rate
growing equity mortgage loans (GEMs);  (d) fixed-rate  mortgage loans secured by
manufactured (mobile) homes (MHs); (e) mortgage loans on multifamily residential
properties  under   construction   (CLCs);   (f)  mortgage  loans  on  completed
multifamily  projects  (PLCs);  (g) fixed-rate  mortgage loans that use escrowed
funds to reduce the borrower's  monthly  payments  during the early years of the
mortgage loans (buydown mortgage loans); and (h) mortgage loans that provide for
payment  adjustments  based on periodic  changes in  interest  rates or in other
payment terms of the mortgage loans.

o        Fannie Mae Certificates
The Federal National  Mortgage  Association  (FNMA or Fannie Mae) is a federally
chartered and privately owned corporation established under the Federal National
Mortgage Association Charter Act. Fannie Mae was originally  established in 1938
as a U.S.  government agency designed to provide  supplemental  liquidity to the
mortgage market and was reorganized as a stockholder-owned and privately managed
corporation by  legislation  enacted in 1968.  Fannie Mae acquires  capital from
investors who would not ordinarily invest in mortgage loans directly and thereby
expands the total amount of funds  available for housing.  This money is used to
buy home mortgage loans from local lenders,  replenishing  the supply of capital
available for mortgage lending.

Fannie Mae  certificates  represent a pro rata  interest in one or more pools of
FHA Loans,  VA Loans,  or, most  commonly,  conventional  mortgage  loans (i.e.,
mortgage loans that are not insured or guaranteed by a  governmental  agency) of
the following types: (a) fixed-rate level payment mortgage loans; (b) fixed-rate
growing equity mortgage loans; (c) fixed-rate  graduated payment mortgage loans;
(d) adjustable-rate mortgage loans; and (e) fixed-rate mortgage loans secured by
multifamily projects.

Fannie  Mae  certificates  entitle  the  registered  holder to  receive  amounts
representing  a pro rata interest in scheduled  principal and interest  payments
(at the  certificate's  pass-through  rate,  which is net of any  servicing  and
guarantee fees on the underlying mortgage loans), any principal prepayments, and
a  proportionate  interest in the full  principal  amount of any  foreclosed  or
otherwise  liquidated mortgage loan. The full and timely payment of interest and
repayment of principal on each Fannie Mae  certificate  is  guaranteed by Fannie
Mae;  this  guarantee  is not  backed by the full  faith and  credit of the U.S.
government.

o        Freddie Mac Certificates
The Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac) is a corporate
instrumentality  of the United States  created  pursuant to the  Emergency  Home
Finance  Act of 1970  (FHLMC  Act),  as  amended.  Freddie  Mac was  established
primarily for the purpose of increasing the availability of mortgage credit. Its
principal activity consists of purchasing  first-lien  conventional  residential
mortgage  loans  (and  participation  interests  in  such  mortgage  loans)  and
reselling  these  loans in the  form of  mortgage-backed  securities,  primarily
Freddie Mac certificates.

Freddie Mac  certificates  represent a pro rata  interest in a group of mortgage
loans (a Freddie Mac certificate  group)  purchased by Freddie Mac. The mortgage
loans underlying  Freddie Mac certificates  consist of fixed- or adjustable-rate
mortgage  loans  with  original  terms to  maturity  of between 10 and 30 years,
substantially  all of which are secured by  first-liens  on one- to  four-family
residential  properties or  multifamily  projects.  Each mortgage loan must meet
standards  set  forth in the FHLMC  Act.  A Freddie  Mac  certificate  group may
include whole loans, participation interests in whole loans, undivided interests
in whole loans,  and  participations  composing  another Freddie Mac certificate
group.

Freddie Mac guarantees to each  registered  holder of a Freddie Mac  certificate
the timely  payment of interest  at the rate  provided  for by the  certificate.
Freddie Mac also guarantees  ultimate collection of all principal on the related
mortgage  loans,  without  any  offset  or  deduction,  but  generally  does not
guarantee the timely repayment of principal.  Freddie Mac may remit principal at
any time after default on an underlying mortgage loan, but no later than 30 days
following (a) foreclosure  sale, (b) payment of a claim by any mortgage insurer,
or (c) the expiration of any right of redemption, whichever occurs later, and in
any event no later than one year after  demand has been made upon the  mortgager
for accelerated payment of principal.  Obligations guaranteed by Freddie Mac are
not backed by the full faith and credit of the U.S. government.

o        Collateralized Mortgage Obligations (CMOs)
A  CMO  is  a  multiclass  bond  backed  by  a  pool  of  mortgage  pass-through
certificates or mortgage loans.  CMOs may be  collateralized  by (a) Ginnie Mae,
Fannie Mae, or Freddie Mac  pass-through  certificates,  (b) unsecured  mortgage
loans  insured  by the  Federal  Housing  Administration  or  guaranteed  by the
Department of Veterans' Affairs, (c) unsecuritized  conventional  mortgages,  or
(d) any combination thereof.

In  structuring  a CMO,  an issuer  distributes  cash  flow from the  underlying
collateral over a series of classes called tranches. Each CMO is a set of two or
more  tranches,  with  average  lives and cash flow  patterns  designed  to meet
specific investment  objectives.  The average life expectancies of the different
tranches in a four-part  deal, for example,  might be two, five,  seven,  and 20
years.

As payments on the underlying mortgage loans are collected,  the CMO issuer pays
the coupon rate of interest to the  bondholders in each tranche.  At the outset,
scheduled  and  unscheduled  principal  payments  go to  investors  in the first
tranches.  Investors in later tranches do not begin receiving principal payments
until the prior  tranches  are paid off.  This  basic  type of CMO is known as a
sequential pay or plain vanilla CMO.

Some CMOs are structured so that the prepayment or market risks are  transferred
from one tranche to another.  Prepayment  stability is improved in some tranches
if other tranches absorb more prepayment variability.

The final  tranche of a CMO often  takes the form of a Z-bond,  also known as an
accrual  bond or accretion  bond.  Holders of these  securities  receive no cash
until the earlier  tranches  are paid in full.  During the period that the other
tranches are outstanding,  periodic  interest  payments are added to the initial
face amount of the Z-bond but are not paid to investors. When the prior tranches
are retired, the Z-bond receives coupon payments on its higher principal balance
plus any principal prepayments from the underlying mortgage loans. The existence
of a Z-bond tranche helps stabilize cash flow patterns in the other tranches. In
a changing interest rate environment,  however, the value of the Z-bond tends to
be more volatile.

As CMOs have evolved, some classes of CMO bonds have become more prevalent.  The
planned  amortization  class (PAC) and targeted  amortization  class (TAC),  for
example,  were designed to reduce prepayment risk by establishing a sinking-fund
structure.  PAC and TAC bonds  assure to varying  degrees  that  investors  will
receive payments over a predetermined period under various prepayment scenarios.
Although  PAC and TAC bonds are  similar,  PAC bonds are better  able to provide
stable cash flows under various  prepayment  scenarios than TAC bonds because of
the order in which these tranches are paid.

The existence of a PAC or TAC tranche can create higher levels of risk for other
tranches in the CMO because the  stability of the PAC or TAC tranche is achieved
by creating at least one other  tranche-known as a companion bond,  support,  or
non-PAC  bond--that  absorbs the  variability of principal  cash flows.  Because
companion bonds have a high degree of average life  variability,  they generally
pay a higher yield. A TAC bond can have some of the prepayment  variability of a
companion bond if there is also a PAC bond in the CMO issue.

Floating-rate  CMO tranches  (floaters)  pay a variable rate of interest that is
usually  tied  to the  London  Interbank  Offered  Rate  (LIBOR).  Institutional
investors with  short-term  liabilities,  such as commercial  banks,  often find
floating-rate  CMOs  attractive  investments.  "Super  floaters"  (which float a
certain percentage above LIBOR) and "inverse floaters" (which float inversely to
LIBOR) are variations on the floater  structure  that have highly  variable cash
flows.

o        Stripped Mortgage-Backed Securities (Short-Term Government only)
Stripped  mortgage  securities  are created by  segregating  the cash flows from
underlying  mortgage  loans or  mortgage  securities  to create  two or more new
securities,  each  with a  specified  percentage  of the  underlying  security's
principal or interest payments. Mortgage securities may be partially stripped so
that each  investor  class  receives  some  interest  and some  principal.  When
securities are completely stripped,  however, all of the interest is distributed
to holders of one type of security,  known as an interest-only  security, or IO,
and all of the principal is  distributed  to holders of another type of security
known  as  a  principal-only  security,  or  PO.  Strips  can  be  created  in a
pass-through structure or as tranches of a CMO.

The  market  values  of IOs and POs are  very  sensitive  to  interest  rate and
prepayment rate fluctuations.  POs, for example, increase (or decrease) in value
as interest rates decline (or rise). The price behavior of these securities also
depends  on  whether  the  mortgage  collateral  was  purchased  at a premium or
discount to its par value. Prepayments on discount coupon POs generally are much
lower than  prepayments on premium coupon POs. IOs may be used to hedge a fund's
other investments  because prepayments cause the value of an IO strip to move in
the opposite direction from other mortgage-backed securities.

o        Adjustable-Rate Mortgage Loans (ARMS)
ARMs  eligible for  inclusion in a mortgage  pool will  generally  provide for a
fixed initial mortgage  interest rate for a specified period of time,  generally
for either the first three,  six, 12, 13, 36, or 60 scheduled  monthly payments.
Thereafter,  the  interest  rates are  subject to periodic  adjustment  based on
changes in an index.

ARMs have minimum and maximum rates beyond which the mortgage  interest rate may
not vary over the  lifetime of the loan.  Certain  ARMs  provide for  additional
limitations on the maximum amount by which the mortgage interest rate may adjust
for any  single  adjustment  period.  Negatively  amortizing  ARMs  may  provide
limitations on changes in the required monthly  payment.  Limitations on monthly
payments can result in monthly payments that are greater or less than the amount
necessary  to  amortize  a  negatively  amortizing  ARM by its  maturity  at the
interest rate in effect during any particular month.

There are two types of indices that provide the basis for ARM rate  adjustments:
those based on market rates and those based on a calculated  measure,  such as a
cost of funds index or a moving  average of mortgage  rates.  Commonly  utilized
indices include the one-year,  three-year,  and five-year constant maturity U.S.
Treasury  rates (as  reported by the Federal  Reserve  Board) ; the  three-month
Treasury  bill  rate;  the  180-day  Treasury  bill rate;  rates on  longer-term
Treasury securities;  the Eleventh District Federal Home Loan Bank Cost of Funds
Index  (EDCOFI);  the  National  Median  Cost of  Funds  Index;  the  one-month,
three-month,  six-month,  or one-year London Interbank Offered Rate (LIBOR);  or
six-month  CD  rates.  Some  indices,  such as the  one-year  constant  maturity
Treasury rate or three-month LIBOR, are highly correlated with changes in market
interest rates. Other indexes, such as the EDCOFI, tend to lag behind changes in
market rates and be somewhat less volatile over short periods of time.

The EDCOFI  reflects the monthly  weighted  average cost of funds of savings and
loan  associations  and savings banks whose home offices are located in Arizona,
California,  and Nevada (the Federal Home Loan Bank  Eleventh  District) and who
are member institutions of the Federal Home Loan Bank of San Francisco (the FHLB
of San Francisco),  as computed from  statistics  tabulated and published by the
FHLB of San Francisco.  The FHLB of San Francisco normally announces the Cost of
Funds Index on the last  working day of the month  following  the month in which
the cost of funds was incurred.

One-year and three-year Constant Maturity Treasury (CMT) rates are calculated by
the  Federal  Reserve  Bank of New York,  based on daily  closing  bid yields on
actively traded Treasury  securities  submitted by five leading  broker-dealers.
The median bid yields are used to construct a daily yield curve.

The National  Median Cost of Funds Index,  similar to the EDCOFI,  is calculated
monthly by the Federal Home Loan Bank Board (FHLBB) and  represents  the average
monthly  interest  expenses on  liabilities  of member  institutions.  A median,
rather than an arithmetic mean, is used to reduce the effect of extreme numbers.

The London  Interbank  Offered Rate Index  (LIBOR) is the rate at which banks in
London offer Eurodollars in trades between banks. LIBOR has become a key rate in
the U.S.  domestic  money  market  because it is  perceived  to reflect the true
global cost of money.The manager may invest in ARMs whose periodic interest rate
adjustments are based on new indices as these indices become available.

Inflation-Indexed Treasury Securities
Inflation-indexed Treasury securities are Treasury securities with a final value
and interest  payment  stream  linked to the inflation  rate.  Inflation-indexed
Treasury securities may be issued in either note or bond form. Inflation-indexed
Treasury notes have maturities of at least one year, but not more than 10 years.
Inflation-indexed Treasury bonds have maturities of more than 10 years.

Inflation-indexed  Treasury securities may be attractive to investors seeking an
investment  backed by the full  faith and  credit  of the U.S.  government  that
provides a return in excess of the rate of inflation.  These  securities are new
to the U.S. market, having first been sold in January 1997. There is uncertainty
as to how these securities will be treated by the marketplace.  See "Development
of Inflation-Indexed  Securities Market" on page 18. Inflation-indexed  Treasury
securities are auctioned and issued on a quarterly basis.

o        Structure And Inflation Index
The principal value of inflation-indexed Treasury securities will be adjusted to
reflect changes in the level of inflation. The index for measuring the inflation
rate for  inflation-indexed  Treasury securities is the non-seasonally  adjusted
U.S.  City  Average  All Items  Consumer  Price  Index  for All Urban  Consumers
published monthly by the U.S. Department of Labor's Bureau of Labor Statistics.

Semiannual  coupon  interest  payments  are  made at a fixed  percentage  of the
inflation-indexed  principal value. The coupon rate for the semiannual  interest
rate of each issuance of inflation-indexed  Treasury securities is determined at
the time the securities are sold to the public (i.e., by competitive bids in the
auction).  The coupon rate will likely  reflect "real  yields"  available in the
Treasury  market;  "real yields" are the prevailing  yields on similar  maturity
Treasury  securities  less  then-prevailing  inflation  expectations.   While  a
reduction  in inflation  will cause a reduction in the interest  payment made on
the  securities,  the  repayment of principal at the maturity of the security is
guaranteed  by the Treasury to be not less than the original  face or par amount
of the security at issuance.

o        Indexing Methodology
The principal value of inflation-indexed Treasury securities will be indexed, or
adjusted, to account for changes in the Consumer Price Index.  Semiannual coupon
interest payment amounts will be determined by multiplying the inflation-indexed
principal  amount by  one-half  the stated  rate of  interest  on each  interest
payment date.

o        Taxation
Taxation  applicable  to  inflation-indexed  Treasury  securities  is similar to
conventional  bonds. Both interest payments and the difference  between original
principal  and the  inflation-adjusted  principal  will be treated  as  interest
income  subject to taxation.  Interest  payments  are taxable  when  received or
accrued. The inflation adjustment to the principal is subject to tax in the year
adjustment  is made,  not at  maturity  of the  security  when the cash from the
repayment of principal is received. If an upward adjustment has been made (which
typically should happen),  investors in non-tax deferred accounts will pay taxes
on this  amount  currently.  Decreases  in the  indexed  principal  can  only be
deducted from current or previous interest payments reported as income.

Inflation-indexed  Treasury  securities  therefore  have a  potential  cash flow
mismatch   to  an   investor,   since   investors   must   pay   taxes   on  the
inflation-adjusted  principal before the repayment of principal is received.  It
is  possible  that,   particularly  for  high  income  tax  bracket   investors,
inflation-indexed  Treasury  securities  would not generate  enough  income in a
given year to cover the tax  liability it could  create.  This is similar to the
current tax treatment for zero coupon bonds and other  discount  securities.  If
inflation-indexed Treasury securities are sold prior to maturity, capital losses
or gains are realized in the same manner as traditional bonds.

Inflation-Adjusted Treasury, however, distributes all income on a monthly basis.
Investors in Inflation-Adjusted  Treasury will receive dividends which represent
both   the   interest   payments   and   the   principal   adjustments   of  the
inflation-indexed   securities   held  in  its   portfolio.   An  investment  in
Inflation-Adjusted  Treasury  may  therefore  be a means to avoid  the cash flow
mismatch  associated with a direct investment in  inflation-indexed  securities.
For more  information  about taxes and their effect on you as an investor in the
fund, see "Taxes," on page 29.

o        U.S Government Agencies
A number of U.S. government agencies and government-sponsored  organizations may
issue  inflation-indexed  securities.  Some U.S. government agencies have issued
inflation-indexed  securities whose design mirrors that of the inflation-indexed
Treasury securities described on the previous page.

o        Development of Inflation-Indexed Securities Market
The Treasury  securities market is the largest and most liquid securities market
in the world. The  marketability of  inflation-indexed  Treasury  securities and
inflation-indexed  securities  generally may be enhanced over time as additional
inflation-indexed  securities are issued and more  investors  participate in the
market.

Inflation-Adjusted  Treasury  will  purchase  inflation-  indexed  securities at
auction  or in the  secondary  market  as the  managers  deem  appropriate.  The
secondary  market for  inflation-indexed  securities may not be as active as the
secondary market for Treasury and U.S. government agency  fixed-principal  notes
and bonds. In addition, inflation-indexed securities may not be as widely traded
or as well  understood as  fixed-principal  securities,  nor is it known at this
time exactly how the secondary market will develop.

If the number of inflation-indexed securities market participants is limited, it
may result in larger spreads between bid and asked prices for  inflation-indexed
securities than the bid-asked spreads for  fixed-principal  notes and bonds with
similar terms to maturity. Such larger bid-ask spreads normally result in higher
transactions  costs  and/or  lower  returns.  If the  market  does  not  develop
sufficient  liquidity,  large buyers or sellers of these  securities  may have a
disproportionately  negative  impact on the value of the securities  and, hence,
Inflation-Adjusted Treasury's net asset value.

The managers currently believe that the market for inflation-indexed  securities
will  be  sufficient  to  permit  Inflation-Adjusted   Treasury  to  pursue  its
investment   objective.   However,   should  the  market  for  inflation-indexed
securities prove less active than anticipated by the managers,  the managers are
authorized to treat such an environment as an abnormal market condition.  During
such a  period,  Inflation-Adjusted  Treasury  will  not be fully  pursuing  its
investment objective.

o        Share Price Volatility
Inflation-indexed securities are designed to offer a return linked to inflation,
thereby  protecting  future  purchasing  power of the  money  invested  in them.
However, inflation-indexed securities provide this protected return only if held
to maturity.  In  addition,  inflation-indexed  securities  may not trade at par
value.  Real interest  rates (the market rate of interest  less the  anticipated
rate of inflation)  change over time, as a result of many factors,  such as what
investors  are  demanding as a true value for money.  When real rates do change,
inflation-indexed securities prices will be more sensitive to these changes than
conventional  bonds,  since these  securities were sold originally  based upon a
real interest rate that is no longer prevailing.  Should market expectations for
real interest  rates rise,  the price of  inflation-indexed  securities  and the
share price of  Inflation-Adjusted  Treasury  will fall.  Investors  in the fund
should be prepared to accept not only this share price  volatility  but also the
possible adverse tax consequences it may cause.

An  investment  in  securities  featuring  inflation-adjusted  principal  and/or
interest  involves factors not associated with more traditional  fixed-principal
securities. Such factors include the possibility that the inflation index may be
subject to significant  changes in interest rates, that changes in the index may
or may not correlate to changes in interest rates  generally or changes in other
indices, that the resulting interest may be greater or less than that payable on
other securities of similar maturities.  In the event of sustained deflation, it
is   possible   that  the   amount  of   semiannual   interest   payments,   the
inflation-adjusted  principal  of the  security  and the  value of the  stripped
components,   will  decrease.  If  any  of  these  possibilities  are  realized,
Inflation-Adjusted Treasury's net asset value could be negatively affected.

Repurchase Agreements
Each fund, with the exception of Capital Preservation and Government Agency, may
invest in repurchase  agreements  when such  transactions  present an attractive
short-term  return on cash that is not  otherwise  committed  to the purchase of
securities pursuant to the investment policies of that fund.

A  repurchase  agreement  occurs  when,  at  the  time  the  fund  purchases  an
interest-bearing  obligation,  the seller (a bank or a broker-dealer  registered
under  the  Securities  Exchange  Act of  1934)  agrees  to  repurchase  it on a
specified  date in the future at an  agreed-upon  price.  The  repurchase  price
reflects  an  agreed-upon  interest  rate  during the time the  fund's  money is
invested in the security.

Because  the  security  purchased  constitutes  collateral  for  the  repurchase
obligation,  a repurchase  agreement can be considered a loan  collateralized by
the security purchased.  The fund's risk is the ability of the seller to pay the
agreed-upon repurchase price on the repurchase date. If the seller defaults, the
fund may incur costs in  disposing  of the  collateral,  which would  reduce the
amount realized  thereon.  If the seller seeks relief under the bankruptcy laws,
the  disposition of the collateral may be delayed or limited.  To the extent the
value of the security decreases, the fund could experience a loss.

Each of the funds,  with the exception of Capital  Preservation  and  Government
Agency,  may invest in  repurchase  agreements  with  respect to any security in
which that fund is authorized to invest,  even if the remaining  maturity of the
underlying  security  would make that security  ineligible  for purchase by such
fund.

When-Issued and Forward Commitment Agreements
The funds may sometimes  purchase new issues of  securities on a when-issued  or
forward commitment basis in which the transaction price and yield are each fixed
at the time the  commitment is made,  but payment and delivery occur at a future
date (typically 15 to 45 days later).

When purchasing  securities on a when-issued or forward commitment basis, a fund
assumes  the rights  and risks of  ownership,  including  the risks of price and
yield  fluctuations.  While the fund will make  commitments  to purchase or sell
securities with the intention of actually  receiving or delivering  them, it may
sell the securities  before the settlement date if doing so is deemed  advisable
as a matter of investment strategy.

In purchasing  securities on a when-issued or forward  commitment  basis, a fund
will  establish  and maintain  until the  settlement  date a segregated  account
consisting of cash, cash equivalents or other  appropriate  liquid securities in
an amount  sufficient to meet the purchase price. When the time comes to pay for
the when-issued  securities,  the fund will meet its obligations  with available
cash, through the sale of securities,  or, although it would not normally expect
to do so, by selling the  when-issued  securities  themselves  (which may have a
market  value  greater  or less than the  fund's  payment  obligation).  Selling
securities to meet  when-issued or forward  commitment  obligations may generate
taxable capital gains or losses.

As an operating policy, no fund will commit more than 50% of its total assets to
when-issued or forward  commitment  agreements.  If fluctuations in the value of
securities  held cause more than 50% of a fund's  total  assets to be  committed
under when-issued or forward  commitment  agreements,  the advisor need not sell
such agreements, but it will be restricted from entering into further agreements
on  behalf  of the  fund  until  the  percentage  of  assets  committed  to such
agreements is below 50% of total assets.


Roll Transactions
A fund may sell a security  and at the same time make a  commitment  to purchase
the  same or a  comparable  security  at a  future  date  and  specified  price.
Conversely,  a  fund  may  purchase  a  security  and at the  same  time  make a
commitment  to sell  the same or a  comparable  security  at a  future  date and
specified price. These types of transactions are executed simultaneously in what
are known as  dollar-rolls,  cash and  carry,  or  financing  transactions.  For
example, a broker-dealer may seek to purchase a particular  security that a fund
owns. The fund will sell that security to the broker-dealer  and  simultaneously
enter into a forward commitment  agreement to buy it back at a future date. This
type of  transaction  generates  income for the fund if the dealer is willing to
execute  the  transaction  at a  favorable  price in order to acquire a specific
security.  As  an  operating  policy,  the  advisor  limits  forward  commitment
transactions  (including roll  transactions) to 35% of a fund's total assets and
will  not  enter  into  when-issued  or  forward  commitment  transactions  with
settlement dates that exceed 120 days.

When engaging in roll transactions,  the fund will maintain until the settlement
date a segregated account consisting of cash or appropriate liquid securities in
an amount sufficient to meet the purchase price, as described above.

Short-Term Securities
Under certain circumstances, the non-money market funds may invest in short-term
municipal or U.S.  government  securities,  including  money market  instruments
(short-term  securities).  If a fund invests in U.S.  government  securities,  a
portion of dividends paid to shareholders  will be taxable at the federal level,
and may be taxable at the state level, as ordinary income.  However, the advisor
intends to minimize such  investments  and, when suitable  short-term  municipal
securities are unavailable, may allow the funds to hold cash to avoid generating
taxable dividends.

Except as otherwise required for temporary defensive purposes,  the advisor does
not expect the non-money market funds to invest more than 35% of total assets in
short-term securities.

Other Investment Companies
Pursuant to an  exemptive  order from the  Securities  and  Exchange  Commission
(SEC), each non-money market fund may invest in shares of the money market funds
to facilitate  cash  management  provided that the investment is consistent with
the funds' investment policies and restrictions.

The  non-money  market funds may invest up to 5% of their total assets in shares
of the money market funds.


INVESTMENT POLICIES
Unless otherwise indicated,  with the exception of the percentage limitations on
borrowing,  the  restrictions  apply at the time  transactions are entered into.
Accordingly,  any later  increase or decrease  beyond the  specified  limitation
resulting  from a change  in a fund's  net  assets  will  not be  considered  in
determining whether it has complied with its investment restrictions.

For purposes of the funds' investment restrictions,  the party identified as the
"issuer"  of a  municipal  security  depends on the form and  conditions  of the
security.  When the assets and revenues of a political  subdivision are separate
from those of the government  that created the  subdivision  and the security is
backed only by the assets and revenues of the  subdivision,  the  subdivision is
deemed the sole  issuer.  Similarly,  in the case of an  Industrial  Development
Bond,   if  the  bond  were  backed  only  by  the  assets  and  revenues  of  a
non-governmental  user,  the  non-governmental  user  would be  deemed  the sole
issuer. If, in either case, the creating government or some other entity were to
guarantee the security,  the guarantee  would be considered a separate  security
and treated as an issue of the guaranteeing entity.


Fundamental Investment Policies
The  funds'  investment  restrictions  are set  forth  below.  These  investment
restrictions  are  fundamental  and may not be  changed  without  approval  of a
majority of the  outstanding  votes of  shareholders of a fund, as determined in
accordance with the Investment Company Act.

For purposes of the investment  restriction  relating to  concentration,  a fund
shall not purchase any  securities  that would cause 25% or more of the value of
the fund's total assets at the time of purchase to be invested in the securities
of one or more issuers  conducting  their principal  business  activities in the
same  industry,  provided  that  (a)  there is no  limitation  with  respect  to
obligations issued or guaranteed by the U.S. government, any state, territory or
possession  of the United  States,  the  District  of  Columbia  or any of their
authorities,   agencies,   instrumentalities   or  political   subdivisions  and
repurchase  agreements  secured by such  instruments,  (b) wholly owned  finance
companies  will be considered to be in the  industries of their parents if their
activities are primarily related to financing the activities of the parents, (c)
utilities will be divided  according to their  services,  for example,  gas, gas
transmission, electric and gas, electric and telephone will each be considered a
separate  industry,  and (d) personal credit and business credit businesses will
be considered separate industries.

                  purposes (not for  leveraging or  investment) in an amount not
                  exceeding  33-1/3% of the fund's total assets  (including  the
                  amount borrowed) less liabilities (other than borrowings).
- ----------------- --------------------------------------------------------------
Lending           A fund may not lend any security or make any other loan if, as
                  a result,  more than  33-1/3% of the fund's total assets would
                  be lent to other parties,  except, (i) through the purchase of
                  debt securities in accordance  with its investment  objective,

                  investment in securities or other  instruments  backed by real
                  estate or securities of companies  that deal in real estate or

Diversification   A fund may not purchase additional investment securities at any time during which outstanding
                  borrowings exceed 5% of the total assets of the fund.
- ----------------- -----------------------------------------------------------------------------------------------
Futures and       The money market funds may not purchase or sell futures contracts or call options. This
options [money    limitation does not apply to options attached to, or acquired or traded together with, their

Liquidity         A fund may not purchase any security or enter into a repurchase agreement if, as a result,
                  more than 15% of its net assets (10% for the money market funds) would be invested in
                  repurchase agreements not entitling the holder to payment of principal and interest within
                  seven days and in securities that are illiquid by virtue of legal or contractual restrictions

                  in connection with futures contracts and options on futures contracts shall not constitute
                  purchasing securities on margin.

TEMPORARY DEFENSIVE MEASURES
For temporary defensive  purposes,  a fund may invest in securities that may not
fit its investment objective or its stated market.  During a temporary defensive
period, a fund may direct its assets to the following investment vehicles:

>>       interest-bearing bank accounts or Certificates of Deposit

>>       U.S. government securities and repurchase agreements  collateralized by
         U.S. government securities

>>       money market funds


PORTFOLIO TURNOVER
Under normal  conditions,  the funds' annual  portfolio  turnover  rates are not
expected to exceed 100%.  Because a higher  turnover rate increases  transaction
costs and may increase taxable capital gains,  the managers  carefully weigh the
potential benefits of short-term investing against these considerations.

The funds' portfolio turnover rates (except those of the money market funds) are
listed in the  Financial  Highlights  table in the  Prospectus.  Because  of the
short-term  nature of the money market funds'  investments,  portfolio  turnover
rates are not generally used to evaluate their trading activities.


MANAGEMENT

THE BOARD OF TRUSTEES
The Board of Trustees  oversees the  management  of the funds and meets at least
quarterly  to  review  reports  about  fund  operations.  Although  the Board of
Trustees  does  not  manage  the  funds,  it has  hired  the  advisor  to do so.
Two-thirds of the trustees are independent of the funds' advisor;  that is, they
are not employed by and have no financial interest in the advisor.

The  individuals  listed in the  following  table  whose  names are marked by an
asterisk (*) are  interested  persons of the funds (as defined in the Investment
Company Act) by virtue of, among other  considerations,  their  affiliation with
either the funds; the advisor, American Century Investment Management, Inc.; the
funds' agent for transfer and administrative services, American Century Services
Corporation  (ACSC); the parent  corporation,  American Century Companies,  Inc.
(ACC) or ACC's subsidiaries; the funds' distribution agent and co-administrator,
Funds  Distributor,  Inc.  (FDI);  or other funds  advised by the advisor.  Each
trustee  listed  below  serves  as a trustee  or  director  of seven  registered
investment  companies in the American  Century  family of funds,  which are also
advised by the advisor.

Compensation of Trustees
The  trustees  also  serve  as  trustees  for six  American  Century  investment
companies other than American Century  Government Income Trust. Each trustee who
is not an interested  person as defined in the  Investment  Company Act receives
compensation  for  service as a member of the Board of all seven such  companies
based on a schedule  that is based on the number of  meetings  attended  and the
assets of the funds for which the meetings are held. These fees and expenses are
divided among the seven investment companies based, in part, upon their relative
net assets.  Under the terms of the management  agreement with the advisor,  the
funds are responsible for paying such fees and expenses.

The  table  presented  shows the  aggregate  compensation  paid for the  periods
indicated by the Trust and by the American Century family of funds as a whole to
each  trustee  who is not an  interested  person as  defined  in the  Investment
Company Act.

(1) Includes  compensation  paid to the  trustees  during the fiscal  year ended
    March 31, 1999,  and also includes  amounts  deferred at the election of the
    trustees under the American Century Mutual Funds Deferred  Compensation Plan
    for  Non-Interested  Directors  and  Trustees.  The  total  amount  deferred
    compensation  included in the  preceding  table is as follows:  info not yet
    available
(2) Includes  compensation  paid by the seven investment  company members of the
    American Century family of funds served by this Board.

The Trust has  adopted  the  American  Century  Deferred  Compensation  Plan for
Non-Interested  Directors and Trustees. Under the plan, the independent trustees
may defer  receipt of all or any part of the fees to be paid to them for serving
as trustees.

Under the plan, all deferred fees are credited to an account  established in the
name of the  trustees.  The amounts  credited to the  account  then  increase or
decrease,  as the case may be, in accordance with the performance of one or more
of the American  Century  funds that are  selected by the  trustee.  The account
balance  continues  to  fluctuate  in  accordance  with the  performance  of the
selected  fund or funds  until  final  payment of all  amounts  credited  to the
account.  Trustees are allowed to change their  designation of mutual funds from
time to time.

No deferred  fees are payable until such time as a trustee  resigns,  retires or
otherwise  ceases to be a member of the Board of Trustees.  Trustees may receive
deferred fee account  balances either in a lump sum payment or in  substantially
equal installment payments to be made over a period not to exceed 10 years. Upon
the death of a trustee,  all remaining deferred fee account balances are paid to
the trustee's beneficiary or, if none, to the trustee's estate.

The plan is an unfunded  plan and,  accordingly,  the Trust has no obligation to
segregate  assets to secure or fund the deferred fees. The rights of trustees to
receive  their  deferred  fee account  balances  are the same as the rights of a
general unsecured  creditor of the Trust. The plan may be terminated at any time
by the  administrative  committee of the plan. If  terminated,  all deferred fee
account balances will be paid in a lump sum.

No deferred  fees were paid to any trustee under the plan during the fiscal year
ended March 31, 1999.


OFFICERS
Background  information  for the  officers of the Trust is provided  below.  All
persons named as officers of the Trust also serve in similar  capacities for the
12 other investment companies advised by ACIM. Not all officers of the Trust are
listed;  only those  officers  with  policy-making  functions  for the Trust are
listed.  No officer is  compensated  for his or her service as an officer of the
Trust. The individuals  listed in the table below are interested  persons of the
funds (as  defined in the  Investment  Company  Act) by virtue of,  among  other
considerations,   their   affiliation  with  either  the  funds,  ACC  or  ACC's

                                                                    Shares

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






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

The funds are unaware of any other  shareholders,  beneficial or of record,  who
own more  than 5% of a fund's  outstanding  shares.  As of June  30,  1999,  the
officers and trustees of the funds,  as a group,  own less than 1% of any fund's
outstanding shares.


SERVICE PROVIDERS
The funds have no employees. To conduct its day-to-day activities, the Trust has
hired a number of  service  providers.  Each  service  provider  has a  specific
function to fill on behalf of the Trust and is described below.

ACIM and ACSC are both wholly owned by ACC.  James E.  Stowers Jr.,  Chairman of
ACC, controls ACC by virtue of his ownership of a majority of its voting stock.


INVESTMENT ADVISOR
The Trust has an  investment  management  agreement  with the advisor,  American
Century  Investment  Management,  Inc., dated August 1, 1997. This agreement was
approved by the shareholders of each of the funds on July 30, 1997.

A description of the  responsibilities  of the advisor appears in the Prospectus
under the caption "Management."

For the services provided to the funds, the advisor receives a monthly fee based
on a percentage of the average net assets of the fund.  The annual rate at which
this fee is assessed is determined  monthly in a two-step process:  First, a fee
rate  schedule  is applied  to the assets of all of the funds of its  investment
category managed by the advisor (the Investment Category Fee). For example, when
calculating  the fee for a money  market  fund,  all of the  assets of the money
market  funds  managed  by the  advisor  are  aggregated.  The three  investment
categories  are money  market  funds,  bond funds and equity  funds.  Second,  a
separate fee rate  schedule is applied to the assets of all of the funds managed
by the advisor (the Complex Fee).  The  Investment  Category Fee and the Complex
Fee are then added to determine the unified  management  fee payable by the fund
to the advisor.

The  schedules  by which the  Investment  Category  Fees are  determined  are as
follows:

On the first  business day of each month,  the funds pay a management fee to the
advisor for the previous  month at the specified  rate. The fee for the previous
month  is  calculated  by  multiplying  the  applicable  fee for the fund by the
aggregate average daily closing value of a fund's net assets during the previous
month  by a  fraction,  the  numerator  of which  is the  number  of days in the
previous month and the denominator of which is 365 (366 in leap years).

The  management  agreement  shall  continue  in effect  until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the funds'
Board of Trustees, or by the vote of a majority of outstanding votes (as defined
in the Investment Company Act) and (2) by the vote of a majority of the trustees
of the funds who are not parties to the agreement or  interested  persons of the
advisor,  cast in person at a meeting  called for the  purpose of voting on such
approval.

The management  agreement provides that it may be terminated at any time without
payment  of any  penalty  by the  funds'  Board of  Trustees,  or by a vote of a
majority of outstanding  votes,  on 60 days' written notice to the advisor,  and
that it shall be automatically terminated if it is assigned.

The  management  agreement  provides that the advisor shall not be liable to the
funds or its  shareholders  for  anything  other than willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations and duties.

The  management  agreement  also  provides  that the advisor  and its  officers,
trustees and employees may engage in other  business,  devote time and attention
to any other  business  whether of a similar or  dissimilar  nature,  and render
services to others.

Certain  investments may be appropriate for the funds and also for other clients
advised by the advisor. Investment decisions for the funds and other clients are
made with a view to  achieving  their  respective  investment  objectives  after
consideration  of such factors as their current  holdings,  availability of cash
for investment and the size of their investment generally. A particular security
may be bought or sold for only one client or fund,  or in different  amounts and
at  different  times  for more than one but less than all  clients  or fund.  In
addition,  purchases  or sales of the same  security may be made for two or more
clients or fund on the same date.  Such  transactions  will be  allocated  among
clients in a manner  believed by the advisor to be  equitable  to each.  In some
cases this procedure  could have an adverse effect on the price or amount of the
securities purchased or sold by a fund.

The advisor may  aggregate  purchase and sale orders of the funds with  purchase
and sale  orders  of its  other  clients  when the  advisor  believes  that such
aggregation  provides  the best  execution  for the funds.  The funds'  Board of
Trustees has approved the policy of the advisor with respect to the  aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the funds  participate at the average share price for all  transactions  in that
security on a given day and share  transaction  costs on a pro rata  basis.  The
advisor  will not  aggregate  portfolio  transactions  of the  funds  unless  it
believes such  aggregation is consistent with its duty to seek best execution on
behalf  of the  funds and the terms of the  management  agreement.  The  advisor
receives  no  additional  compensation  or  remuneration  as a  result  of  such
aggregation.

Prior to August 1, 1997, Benham Management  Corporation served as the investment
advisor to the funds. Benham Management  Corporation was merged into the advisor
in late 1997.

Unified management fees paid by each fund for the fiscal periods ended March 31,
1999, 1998 and 1997, are indicated in the following  table.  Fee amounts are net
of amounts reimbursed or recouped under the funds' previous  investment advisory
agreement with Benham Management Corporation.

DISTRIBUTOR
The  funds'  shares are  distributed  by FDI, a  registered  broker-dealer.  The
distributor  is a wholly  owned,  indirect  subsidiary  of Boston  Institutional
Group,  Inc. The  distributor's  principal  business address is 60 State Street,
Suite 1300, Boston, Massachusetts 02109.

The  distributor  is  the  principal  underwriter  of  the  funds'  shares.  The
distributor makes a continuous,  best efforts underwriting of the funds' shares.
This means that the distributor has no liability for unsold shares.


OTHER SERVICE PROVIDERS

Custodian Banks
Chase Manhattan Bank, 770 Broadway,  10th Floor,  New York, New York 10003-9598,
and Commerce Bank, N.A., 1000 Walnut,  Kansas City,  Missouri 64105, each serves
as  custodian  of the  assets  of the  funds.  The  custodians  take  no part in
determining the investment policies of the funds or in deciding which securities
are purchased or sold by the funds.  The funds,  however,  may invest in certain
obligations of the custodians and may purchase or sell certain  securities  from
or to the custodians.


Independent Accountants
PricewaterhouseCoopers  LLP is the  independent  accountant  of the  funds.  The
address of  PricewaterhouseCoopers  LLP is City Center Square, 1100 Main Street,
Suite 900, Kansas City, Missouri  64105-2140.  As the independent  accountant of
the funds,  PricewaterhouseCoopers  provides services including (1) audit of the
annual  financial  statements for the funds,  (2) assistance and consultation in
connection  with SEC  filings  and (3) review of the annual  federal  income tax
return filed for each fund.


KPMG Peat Marwick LLP, 1000 Walnut,  Suite 1600,  Kansas City,  Missouri  64106,
served as independent  accountants for the funds for the fiscal year ended March
31, 1997, and for all prior periods.


BROKERAGE ALLOCATION
Under the management  agreement  between the funds and the advisor,  the advisor
has the  responsibility  of selecting  brokers and dealers to execute  portfolio
transactions.  In many  transactions,  the  selection of the broker or dealer is
determined by the  availability of the desired  security and its offering price.
In other  transactions,  the  selection of broker or dealer is a function of the
selection  of  market  and the  negotiation  of price,  as well as the  broker's
general  execution and  operational  and financial  capabilities  in the type of
transaction involved. The advisor will seek to obtain prompt execution of orders
at the most favorable  prices or yields.  The advisor may choose to purchase and
sell portfolio  securities to and from dealers who provide services or research,
statistical  and  other  information  to the  funds  and to  the  advisor.  Such
information  or services  will be in addition to and not in lieu of the services
required to be performed  by the  advisor,  and the expenses of the advisor will
not  necessarily  be  reduced as a result of the  receipt  of such  supplemental
information.


INFORMATION ABOUT FUND SHARES
The  Declaration  of Trust  permits the Board of Trustees to issue an  unlimited
number of full and fractional  shares of beneficial  interest without par value,
which may be issued in series  (or  funds).  Shares  issued  are fully  paid and
nonassessable and have no preemptive, conversion or similar rights.

Each fund votes separately on matters  affecting that fund  exclusively.  Voting
rights  are not  cumulative,  so that  investors  holding  more  than 50% of the
Trust's (i.e.,  all funds')  outstanding  shares may be able to elect a Board of
Trustees.  The Trust instituted  dollar-based voting, meaning that the number of
votes you are  entitled to is based upon the dollar  amount of your  investment.
The  election of trustees is  determined  by the votes  received  from all Trust
shareholders  without  regard to  whether a  majority  of shares of any one fund
voted in favor of a particular nominee or all nominees as a group.

Each shareholder has rights to dividends and distributions  declared by the fund
he or she owns and to the net  assets  of such  fund  upon  its  liquidation  or
dissolution  proportionate  to his or her share ownership  interest in the fund.
Shares  of each  fund  have  equal  voting  rights,  although  each  fund  votes
separately on matters affecting that fund exclusively.

Shareholders   of  a   Massachusetts   business   trust  could,   under  certain
circumstances,  be held  personally  liable for its  obligations.  However,  the
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or  obligations  of the Trust.  The  Declaration of Trust also provides for
indemnification and reimbursement of expenses of any shareholder held personally
liable for obligations of the Trust.  The Declaration of Trust provides that the
Trust  will,  upon  request,  assume the  defense of any claim made  against any
shareholder  for any act or  obligation  of the Trust and satisfy  any  judgment
thereon.  The Declaration of Trust further  provides that the Trust may maintain
appropriate insurance (for example,  fidelity,  bonding and errors and omissions
insurance)  for  the  protection  of  the  Trust,  its  shareholders,  trustees,
officers,  employees and agents to cover  possible  tort and other  liabilities.
Thus,  the  risk  of a  shareholder  incurring  financial  loss as a  result  of
shareholder  liability  is limited  to  circumstances  in which both  inadequate
insurance exists and the Trust is unable to meet its obligations.


MULTIPLE CLASS STRUCTURE
The funds' Board of Trustees has adopted a multiple  class plan (the  Multiclass
Plan)  pursuant to Rule 18f-3  adopted by the SEC.  Pursuant  to such plan,  the
funds  may  issue  up  to  three  classes  of  funds:   an  Investor  Class,  an
Institutional Class and an Advisor Class. Not all funds offer all three classes

The Investor Class is made available to investors  directly  without any load or
commission,  for a single unified  management fee. The Institutional and Advisor
Classes are made available to  institutional  shareholders or through  financial
intermediaries   that  do  not  require  the  same  level  of  shareholder   and
administrative  services from the advisor as Investor Class  shareholders.  As a
result,  the advisor is able to charge these classes a lower unified  management
fee. In addition to the management  fee,  however,  the Advisor Class shares are
subject to a Master  Distribution  and  Shareholder  Services Plan. The plan has
been  adopted  by the  funds'  Board of  Trustees  and  initial  shareholder  in
accordance with Rule 12b-1 adopted by the SEC under the Investment Company Act.


RULE 12B-1
Rule 12b-1 permits an  investment  company to pay expenses  associated  with the
distribution  of its shares in accordance  with a plan adopted by the investment
company's Board of Trustees and approved by its  shareholders.  Pursuant to such
rule, the Board of Trustees and initial  shareholder of the funds' Advisor Class
have approved and entered into a Master  Distribution  and Shareholder  Services
Plan (the Plan).

In adopting  the Plan,  the Board of Trustees  [including a majority who are not
interested  persons of the funds (as  defined in the  Investment  Company  Act),
hereafter referred to as the "independent trustees"] determined that there was a
reasonable likelihood that the Plan would benefit the funds and the shareholders
of the  affected  class.  Pursuant to Rule 12b-1,  information  with  respect to
revenues  and  expenses  under the Plan is  presented  to the Board of  Trustees
quarterly for its  consideration in connection with its  deliberations as to the
continuance  of the Plan.  Continuance of the Plan must be approved by the Board
of Trustees  (including a majority of the independent  trustees)  annually.  The
Plan may be amended by a vote of the Board of Trustees  (including a majority of
the independent trustees), except that the Plan may not be amended to materially
increase the amount to be spent for distribution  without  majority  approval of
the shareholders of the affected class. The Plan terminates automatically in the
event of an assignment  and may be  terminated  upon a vote of a majority of the
independent  trustees  or by  vote  of a  majority  of  the  outstanding  voting
securities of the affected class.

All fees paid under the Plan will be made in  accordance  with Section 26 of the
Rules of Fair Practice of the National Association of Securities Dealers (NASD).


MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN
As described in the  Prospectuses,  the funds'  Advisor Class of shares are made
available to participants in employer-sponsored  retirement or savings plans and
to  persons  purchasing  through  financial   intermediaries,   such  as  banks,
broker-dealers  and insurance  companies.  The distributor enters into contracts
with various  banks,  broker-dealers,  insurance  companies and other  financial
intermediaries  with respect to the sale of the funds'  shares and/or the use of
the funds' shares in various  investment  products or in connection with various
financial services.

Certain  recordkeeping  and  administrative  services  that are  provided by the
funds' transfer agent for the Investor Class  shareholders may be performed by a
plan sponsor (or its agents) or by a financial  intermediary for shareholders in
the Advisor Class.  In addition to such services,  the financial  intermediaries
provide various distribution services.

To  enable  the  funds'  shares  to be made  available  through  such  plans and
financial  intermediaries,  and to compensate them for such services, the funds'
investment  manager  has  reduced  its  management  fee by 0.25% per annum  with
respect to the Advisor Class shares and the funds' Board of Trustees has adopted
a Master  Distribution and Shareholder  Services Plan (the  Distribution  Plan).
Pursuant to such Plan,  the Advisor  Class shares pay the  distributor  a fee of
0.50% annually of the aggregate average daily assets of the funds' Advisor Class
shares, 0.25% of which is paid for Shareholder Services (as described below) and
0.25% of which is paid for distribution services.

Payments may be made for a variety of shareholder services,  including,  but not
limited to, (a) receiving,  aggregating  and processing  purchase,  exchange and
redemption  requests  from  beneficial  owners  (including  contract  owners  of
insurance  products  that utilize the funds as underlying  investment  media) of
shares  and  placing   purchase,   exchange  and  redemption   orders  with  the
distributor;  (b) providing  shareholders with a service that invests the assets
of their accounts in shares pursuant to specific or pre-authorized instructions;
(c)  processing  dividend  payments  from a fund on behalf of  shareholders  and
assisting  shareholders in changing dividend options,  account  designations and
addresses; (d) providing and maintaining elective services such as check writing
and wire transfer services;  (e) acting as shareholder of record and nominee for
beneficial owners; (f) maintaining account records for shareholders and/or other
beneficial  owners;  (g) issuing  confirmations of  transactions;  (h) providing
subaccounting  with respect to shares  beneficially  owned by customers of third

BUYING AND SELLING FUND SHARES
Information about buying, selling and exchanging fund shares is contained in the
American  Century  Investor  Services Guide. The guide is available to investors
without charge and may be obtained by calling us.


VALUATION OF A FUND'S SECURITIES
Each  fund's net asset value per share  (NAV) is  calculated  as of the close of
business  of the New York  Stock  Exchange  (the  Exchange),  usually  at 3 p.m.
Central time each day the Exchange is open for business.  The Exchange typically
observes the  following  holidays:  New Year's Day,  Martin Luther King Jr. Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving Day and Christmas Day.  Although the funds expect the same holidays
to be observed in the future,  the Exchange  may modify its holiday  schedule at
any time.

The advisor  typically  completes  its trading on behalf of each fund in various
markets  before the  Exchange  closes for the day.  Each  fund's  share price is
calculated  by adding the value of all  portfolio  securities  and other assets,
deducting   liabilities  and  dividing  the  result  by  the  number  of  shares
outstanding.  Expenses and interest  earned on portfolio  securities are accrued
daily.


MONEY MARKET FUNDS
Securities  held by the money market funds are valued at  amortized  cost.  This
method  involves  valuing an  instrument at its cost and  thereafter  assuming a
constant amortization to maturity of any discount or premium paid at the time of
purchase.  Although this method  provides  certainty in valuation,  it generally
disregards the effect of fluctuating  interest rates on an  instrument's  market
value.  Consequently,  the  instrument's  amortized  cost value may be higher or
lower than its market value, and this discrepancy may be reflected in the funds'
yields. During periods of declining interest rates, for example, the daily yield
on fund  shares  computed as  described  above may be higher than that of a fund
with identical investments priced at market value. The converse would apply in a
period of rising interest rates.

The money market funds  operate  pursuant to  Investment  Company Act Rule 2a-7,
which permits valuation of portfolio  securities on the basis of amortized cost.
As required by the Rule, the Board of Trustees has adopted  procedures  designed
to stabilize, to the extent reasonably possible, a money market fund's price per
share as computed for the purposes of sales and redemptions at $1.00.  While the
day-to-day  operation  of the  money  market  funds  has been  delegated  to the
advisor,   the  quality   requirements   established  by  the  procedures  limit
investments  to certain  instruments  that the Board of Trustees has  determined
present  minimal credit risks and that have been rated in one of the two highest
rating  categories  as  determined by a rating agency or, in the case of unrated
securities,  of comparable  quality.  The procedures require review of the money
market fund's portfolio holdings at such intervals as are reasonable in light of
current market conditions to determine whether the money market fund's net asset
value  calculated  by  using  available  market  quotations  deviates  from  the
per-share  value based on amortized  cost.  The  procedures  also  prescribe the
action to be taken if such deviation should occur.

The Board of Trustees monitors the levels of illiquid securities, however if the
levels are exceeded, they will take action to rectify these levels.

Actions the Board of Trustees may consider under these circumstances include (i)
selling portfolio  securities prior to maturity,  (ii) withholding  dividends or
distributions  from capital,  (iii) authorizing a one-time dividend  adjustment,
(iv)  discounting  share  purchases and  initiating  redemptions in kind, or (v)
valuing portfolio securities at market price for purposes of calculating NAV.


NON-MONEY MARKET FUNDS
Securities  held  by the  non-money  market  funds  normally  are  priced  by an
independent  pricing  service,  provided  that such  prices are  believed by the
advisor to reflect the fair market value of portfolio securities.

Because there are hundreds of thousands of municipal issues outstanding, and the
majority of them do not trade daily, the prices provided by pricing services are
generally  determined  without  regard to bid or last sale  prices.  In  valuing
securities,  the pricing  services  generally  take into  account  institutional
trading activity,  trading in similar groups of securities, and any developments
related to specific securities.  The methods used by the pricing service and the
valuations  so  established  are  reviewed  by the  advisor  under  the  general
supervision  of the Board of  Trustees.  There are a number of pricing  services
available,  and the  advisor,  on the  basis  of  ongoing  evaluation  of  these
services,  may use other pricing  services or discontinue the use of any pricing
service in whole or in part.

Securities  not priced by a pricing  service are valued at the mean  between the
most  recently  quoted  bid and  ask  prices  provided  by  broker-dealers.  The
municipal bond market is typically a "dealer  market";  that is, dealers buy and
sell bonds for their own accounts  rather than for customers.  As a result,  the
spread, or difference  between bid and asked prices, for certain municipal bonds
may differ substantially among dealers.

Securities  maturing within 60 days of the valuation date may be valued at cost,
plus or minus any amortized  discount or premium,  unless the trustees determine
that this would not result in fair valuation of a given  security.  Other assets
and securities for which quotations are not readily available are valued in good
faith at their fair value using methods approved by the Board of Trustees.


TAXES

Federal Income Tax
Each fund intends to qualify  annually as a regulated  investment  company under
Subchapter M of the Internal  Revenue Code of 1986, as amended (the Code). By so
qualifying,  a fund will be exempt from federal and  California  income taxes to
the extent that it distributes  substantially  all of its net investment  income
and net  realized  capital  gains (if any) to  shareholders.  If a fund fails to
qualify  as a  regulated  investment  company,  it will  be  liable  for  taxes,
significantly   reducing  its  distributions  to  shareholders  and  eliminating
shareholders'  ability to treat  distributions  of the funds in the manner  they
were realized by the funds.

Certain  of the bonds  purchased  by the funds may be treated as bonds that were
originally issued at a discount. Original issue discount represents interest for
federal  income tax  purposes  and can  generally  be defined as the  difference
between the price at which a security was issued and its stated redemption price
at maturity. Original issue discount, although no cash is actually received by a
fund until the maturity of the bond, is treated for federal  income tax purposes
as income  earned by a fund over the term of the bond,  and therefore is subject
to the distribution requirements of the Code. The annual amount of income earned
on such a bond by a fund  generally  is  determined  on the basis of a  constant
yield to maturity that takes into account the semiannual  compounding of accrued
interest.  Original  issue discount on an obligation  with interest  exempt from
federal income tax will constitute tax-exempt interest income to the fund.

In addition,  some of the bonds may be  purchased  by a fund at a discount  that
exceeds the  original  issue  discount on such bonds,  if any.  This  additional
discount  represents  market discount for federal income tax purposes.  The gain
realized on the disposition of any bond having market discount generally will be
treated as taxable  ordinary income to the extent it does not exceed the accrued
market discount on such bond (unless a fund elects to include market discount in
income in tax years to which it is  attributable).  Generally,  market  discount
accrues  on a daily  basis for each day the bond is held by a fund on a straight
line basis over the time  remaining to the bond's  maturity.  In the case of any
debt security  having a fixed  maturity date of not more than one year from date
of  issue,  the gain  realized  on  disposition  generally  will be  treated  as
short-term capital gain. In general,  gain realized on disposition of a security
held less than one year is treated as short-term capital gain.

Under the Code,  any  distribution  of a fund's net realized  long-term  capital
gains  designated  by  the  fund  as a  capital  gain  dividend  is  taxable  to
shareholders as long-term capital gains, regardless of the length of time shares
are held.  If a capital  gain  dividend is paid with  respect to any shares of a
fund sold at a loss after  being  held for six months or less,  the loss will be
treated as a long-term  capital loss for tax  purposes.  The Code also  provides
that if a  shareholder  holds  shares  of a fund for six  months  or  less,  the
deduction of any loss on the sale or exchange of those shares is  disallowed  to
the extent that the shareholder received exempt-interest  dividends with respect
to those shares.


State and Local Taxes
Distributions  also may be  subject to state and local  taxes,  even if all or a
substantial  part  of such  distributions  are  derived  from  interest  on U.S.
government  obligations  which,  if you received them directly,  would be exempt
from state income tax. However, most but not all states allow this tax exemption
to pass  through  to fund  shareholders  when a fund pays  distributions  to its
shareholders.  You should  consult your tax advisor about the tax status of such
distributions in your own state.

The  information  above  is only a  summary  of  some of the tax  considerations
affecting the funds and their shareholders.  No attempt has been made to discuss
individual tax consequences.  A prospective  investor should consult with his or
her tax  advisors or state or local tax  authorities  to  determine  whether the
funds are suitable investments.






HOW FUND PERFORMANCE INFORMATION IS CALCULATED
The  funds  may  quote  performance  in  various  ways.  Historical  performance
information will be used in advertising and sales literature.

For the money  market  funds,  yield  quotations  are based on the change in the
value of a hypothetical investment (excluding realized gains and losses from the
sale of securities and unrealized  appreciation  and depreciation of securities)
over a  seven-day  period  (base  period)  and  stated  as a  percentage  of the
investment at the start of the base period (base-period return). The base-period
return is then  annualized  by  multiplying  by 365/7 with the  resulting  yield
figure carried to at least the nearest hundredth of one percent.

Calculations of effective yield begin with the same  base-period  return used to
calculate yield, but the return is then annualized to reflect weekly compounding
according to the following formula:

              Effective Yield = [(Base-Period Return + 1)365/7] - 1

For the non-money  market funds,  yield  quotations  are based on the investment
income per share earned during a particular 30-day period, less expenses accrued
during the period (net  investment  income),  and are  computed by dividing  the
fund's net  investment  income by its share  price on the last day of the period
according to the following formula:

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

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

Total returns quoted in advertising and sales literature  reflect all aspects of
a fund's return,  including the effect of reinvesting dividends and capital gain
distributions (if any) and any change in the fund's NAV during the period.

Average annual total returns are calculated by determining the growth or decline
in value  of a  hypothetical  historical  investment  in a fund  during a stated
period and then calculating the annually  compounded  percentage rate that would
have produced the same result if the rate of growth or decline in value had been
constant  throughout the period.  For example, a cumulative total return of 100%
over 10 years  would  produce an average  annual  return of 7.18%,  which is the
steady  annual  rate that would equal 100%  growth on a  compounded  basis in 10
years.  While average  annual total returns are a convenient  means of comparing
investment alternatives, investors should realize that the funds' performance is
not constant over time, but changes from  year-to-year,  and that average annual
total  returns  represent  averaged  figures as  opposed to actual  year-to-year
performance.

In addition to average annual total returns,  each fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Average annual and cumulative total returns may be quoted
as  percentages  or as  dollar  amounts  and  may  be  calculated  for a  single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital gains and changes in share price) to illustrate the
relationship of these factors and their contributions to total return.


ADDITIONAL PERFORMANCE COMPARISONS
The funds'  performance  may be compared  with the  performance  of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may include  comparisons with funds that, unlike the American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic  data that may be used for such  comparisons  may include,  but are not
limited to, U.S. Treasury bill, note and bond yields,  money market fund yields,
U.S.  government debt and percentage held by foreigners,  the U.S. money supply,
net  free  reserves,  and  yields  on  current-coupon  GNMAs  (source:  Board of

by the Investment Company Institute; Ibbotson Associates,  Stocks, Bonds, Bills,
and  Inflation;  major  indexes of stock  market  performance;  and  indexes and
historical data supplied by major  securities  brokerage or investment  advisory
firms.  The funds  also may  utilize  reprints  from  newspapers  and  magazines
furnished by third parties to illustrate  historical  performance  or to provide
general information about the funds.


PERMISSIBLE ADVERTISING INFORMATION
From  time to  time,  the  funds  may,  in  addition  to any  other  permissible
information,  include the  following  types of  information  in  advertisements,
supplemental  sales literature and reports to  shareholders:  (1) discussions of
general economic or financial principles (such as the effects of compounding and
the benefits of dollar-cost  averaging);  (2)  discussions  of general  economic
trends;  (3)  presentations of statistical data to supplement such  discussions;
(4)  descriptions of past or anticipated  portfolio  holdings for one or more of
the funds;  (5)  descriptions  of investment  strategies  for one or more of the
funds;  (6)  descriptions  or  comparisons  of various  savings  and  investment
products  (including,  but  not  limited  to,  qualified  retirement  plans  and
individual  stocks and  bonds),  which may or may not  include  the  funds;  (7)
comparisons of investment products (including the funds) with relevant market or
industry  indices  or other  appropriate  benchmarks;  (8)  discussions  of fund
rankings or ratings by recognized  rating  organizations;  and (9)  testimonials
describing  the  experience  of persons that have invested in one or more of the
funds. The funds also may include calculations, such as hypothetical compounding
examples,  which describe  hypothetical  investment  results.  Such  performance
examples will be based on an express set of  assumptions  and are not indicative
of the performance of any of the funds.


MULTIPLE CLASS PERFORMANCE ADVERTISING
Pursuant to the Multiple Class Plan, the funds may issue  additional  classes of
existing  funds or  introduce  new funds with  multiple  classes  available  for
purchase.  To the extent a new class is added to an existing  fund,  the manager
may, in compliance with SEC and NASD rules,  regulations and guidelines,  market
the new class of shares  using the  historical  performance  information  of the
original class of shares. When quoting performance information for the new class
of shares for  periods  prior to the first full  quarter  after  inception,  the
original class'  performance will be restated to reflect the expenses of the new
class.  For  periods  after the  first  full  quarter  after  inception,  actual
performance of the new class will be used.

                                PURPOSE OF TRUST
The purpose of the Trust is to provide  investors a managed  investment  company

                                   ARTICLE III
                                     SHARES

SECTION 1.  DIVISION OF BENEFICIAL INTEREST
The  beneficial  interest  in the Trust  shall at all times be  divided  into an
unlimited  number of Shares,  without par value.  Subject to the  provisions  of
Section 6 of this Article III,  each Share shall have voting  rights as provided
in Article V hereof,  and holders of the Shares of any Series  shall be entitled
to receive  dividends,  when and as declared with respect  thereto in the manner
provided in Article VI,  Section 1 hereof.  No Shares shall have any priority or
preference  over any other Share of the same Series with respect to dividends or
distributions  upon  termination of the Trust or of such Series made pursuant to
Article VIII,  Section 4 hereof.  All dividends and distributions  shall be made
ratably among all Shareholders of a particular  Series from the assets belonging
to such Series  according  to the number of Shares of such Series held of record
by each  Shareholder  on the  record  date  for any  dividend  or on the date of
termination,  as the case my be.  Shareholders shall have no preemptive or other
right to subscribe to any additional  Shares or other  securities  issued by the
Trust or any Series.  The  Trustees  may from time to time divide or combine the
Shares of any  particular  Series  into a greater or lesser  number of Shares of
that Series without thereby changing the  proportionate  beneficial  interest of
the Shares of that Series in the assets  belonging  to that Series or in any way
affecting the rights of Shares of any other Series.


SECTION 2.  OWNERSHIP OF SHARES
The  ownership  of  Shares  shall be  recorded  on the  books of the  Trust or a
transfer  or  similar  agent for the  Trust,  which  books  shall be  maintained
separately  for the  Shares  of each  Series.  No  certificates  certifying  the
ownership  of  Shares  shall be  issued  except as the  Trustees  may  otherwise
determine  from time to time.  The Trustees may make such rules as they consider
appropriate for the transfer of Shares of each Series and similar  matters.  The
record books of the Trust as kept by the Trust or any transfer or similar agent,
as the case may be, shall be conclusive as to who are the  Shareholders  of each
Series and as to the number of Shares of each  Series  held from time to time by
each.


SECTION 3.  INVESTMENTS IN THE TRUST
The  Trustees may accept  investments  in the Trust from such  persons,  at such
times,  and on such terms and for such  consideration  as they from time to time
authorize.


SECTION 4.  STATUS OF SHARES AND LIMITATION OF PERSONAL LIABILITY
Shares shall be deemed to be personal  property  giving only the rights provided
in this instrument.  Every  Shareholder by virtue of having become a Shareholder
shall be held to have  expressly  assented and agreed to the terms hereof and to
have become a party hereto.  The death of a Shareholder  during the existence of
the  Trust  shall  not  operate  to  terminate   the  Trust,   nor  entitle  the
representative  of any  deceased  Shareholder  to an  accounting  or to take any
action in court or  elsewhere  against the Trust or the  Trustees,  but entitles
such  representative  only to the right of said deceased  Shareholder under this
Trust.  Ownership of Shares shall not entitle the Shareholder to any title in or
to the whole or any part of the Trust  property or right to call for a partition
or division of the same or for an accounting , nor shall the ownership of Shares
constitute the Shareholders as partners. Neither the Trust nor the Trustees, nor
any  officer,  employee  or  agent of the  Trust  shall  have any  power to bind
personally any  Shareholders,  nor, except as specifically  provided herein,  to
call upon any  Shareholder  for the  payment  of any sum of money or  assessment
whatsoever  other than such as the Shareholder may at any time personally  agree
to pay.


SECTION 5.  POWER OF TRUSTEES TO CHANGE PROVISIONS RELATING TO SHARES
Notwithstanding  any other  provision of this  Declaration  of Trust and without
limiting the power of the Trustees to amend the Declaration of Trust as provided
elsewhere herein, the Trustees shall have the power to amend this Declaration of
Trust,  at any time and from time to time,  in such manner as the  Trustees  may
determine in their sole discretion,  without the need for Shareholder action, so
as to add to, delete, replace or otherwise modify any provisions relating to the
Shares contained in this Declaration of Trust, provided that before adopting any
such amendment without Shareholder approval the Trustees shall determine that it
is consistent with the fair and equitable  treatment of all Shareholders or that
Shareholder  approval  is not  otherwise  required  by  the  1940  Act or  other
applicable law.

Without  limiting the  generality  of the  foregoing,  the Trustees may, for the
above-stated purposes, amend the Declaration of Trust to:

(a)      create one or more Series of Shares (in addition to any Series  already
         existing  or  otherwise)  with such  rights  and  preferences  and such
         eligibility  requirements for investment  therein as the Trustees shall
         determine and  reclassify  any or all  outstanding  Shares as shares of
         particular Series in accordance with such eligibility requirements;

(b)      amend any of the  provisions set forth in paragraphs (a) through (i) of
         Section 6 of this Article III;

(c)      combine one or more Series of Shares into a single Series on such terms
         and conditions as the Trustees shall determine;

(d)      change or eliminate  any  eligibility  requirements  for  investment in
         Shares of any Series, including without limitation,  to provide for the
         issue  of  Shares  of any  Series  in  connection  with any  merger  or
         consolidation  of the  Trust  with  another  trust  or  company  or any
         acquisition  by the Trust of part or all of the assets of another trust
         or investment company;

(e)      change the designation of any Series of Shares;

(f)      change the method of allocating  dividends  among the various Series of
         Shares;

(g)      allocate  any  specific  assets  or  liabilities  of the  Trust  or any
         specific  items of income or expense of the Trust to one or more Series
         of Shares; and

(h)      specifically  allocate  assets to any or all Series of Shares or create
         one or more  additional  Series of Shares which are preferred  over all
         other  Series of Shares in  respect  of assets  specifically  allocated
         thereto  or any  dividends  paid by the Trust  with  respect to any net
         income, however determined, earned from the investment and reinvestment
         of any assets so  allocated  or  otherwise  and provide for any special
         voting or other rights with respect to such Series.


SECTION 6.  ESTABLISHMENT AND DESIGNATION OF SERIES
The  establishment  and  designation  of any Series of Shares shall be effective
upon  resolution  by a  majority  of  the  then  Trustees,  setting  forth  such
establishment  and  designation  and the relative rights and preferences of such
Series,  or as otherwise  provided in such resolution.  Such  establishment  and
designation  shall be set forth in an amendment to this  Declaration of Trust by
execution of a new Schedule A to this Declaration of Trust.

Shares of each Series  established  pursuant to this Section 6, unless otherwise
provided  in the  resolution  establishing  such  Series or as  modified  by the
Multiple Class Plan, shall have the following rights and preferences:

(a)      ASSETS BELONGING TO SERIES. All consideration received by the Trust for
         the issue or sale of Shares of a particular  Series,  together with all
         assets in which such  consideration  is  invested  or  reinvested,  all
         income,  earnings,  profits,  and proceeds thereof from whatever source
         derived,  including,  without limitation, any proceeds derived from the
         sale, exchange or liquidation of such assets, and any funds or payments
         derived from any  reinvestment  of such  proceeds in whatever  form the
         same may be, shall irrevocably  belong to that Series for all purposes,
         subject only to the rights of creditors,  shall be so recorded upon the
         books of account of the Trust,  and are herein  referred  to as "assets
         belonging  to" that  Series.  In the event that  there are any  assets,
         income, earnings, profits and proceeds thereof, funds or payments which
         are not readily  identifiable  as  belonging to any  particular  Series
         (collectively  "General  Assets"),  the Trustees  shall  allocate  such
         General  Assets  to,  between or among any one or more of the Series in
         such manner and on such basis as they, in their sole  discretion,  deem
         fair and equitable, and any General Assets to, between or among any one
         or more of the  Series in such  manner  and on such  basis as they,  in
         their sole discretion,  deem fair and equitable,  and any General Asset
         so allocated to a particular  Series shall belong to that Series.  Each
         such  allocation by the Trustees  shall be conclusive  and binding upon
         the Shareholders of all Series for all purposes.

(b)      LIABILITIES   BELONGING  TO  SERIES.   The  assets  belonging  to  each
         particular Series shall be charged with the liabilities of the Trust in
         respect to that Series and all  expenses,  costs,  charges and reserves
         attributable to that Series,  and any general  liabilities of the Trust
         which are not  readily  identifiable  as  belonging  to any  particular
         Series shall be allocated  and charged by the Trustees to and among any
         one or more of the  Series  in such  manner  and on such  basis  as the
         Trustees  in  their  sole  discretion  deem  fair  and  equitable.  The
         liabilities,  expenses,  costs,  charges,  and reserves so charged to a
         Series  are  herein  referred  to as  "liabilities  belonging  to" that
         Series. Each allocation of liabilities,  expenses,  costs,  charges and
         reserves  by the  Trustee  shall be  conclusive  and  binding  upon the
         holders of all Series for all purposes.  Under no  circumstances  shall
         the assets  allocated or belonging to any particular  Series be charged
         with liabilities attributable to any other Series. All persons who have
         extended credit which has been allocated to particular  Series,  or who
         have a claim or contract  which has been  allocated  to any  particular
         Series,  shall  look only to the assets of that  particular  Series for
         payment of such credit, claim, or contract.

(c)      INCOME,  DISTRIBUTIONS,  AND REDEMPTIONS.  The Trustees shall have full
         discretion,  to the  extent  not  inconsistent  with the 1940  Act,  to
         determine  which  items  shall be treated as income and which  items as
         capital; and each such determination and allocation shall be conclusive
         and binding upon the Shareholders.  Notwithstanding any other provision
         of this  Declaration,  including,  without  limitation,  Article VI, no
         dividend or distribution  (including,  without limitation,  Article VI,
         any  distribution  paid upon termination of the Trust or of any Series)
         with respect to, nor any redemption or repurchase of, the Shares of any
         Series  shall be  effected  by the Trust  other  than  from the  assets
         belonging  to such  Series,  nor,  except as  specifically  provided in
         Section 7 of this Article III, shall any  Shareholder of any particular
         Series  otherwise have any right or claim against the assets  belonging
         to any other Series except to the extent that such Shareholder has such
         a right or claim hereunder as a Shareholder of such other Series.

(d)      VOTING. All Shares of the Trust entitled to vote on a matter shall vote
         separately by Series.  That is, the  Shareholders  of each Series shall
         have the right to approve or disapprove matters affecting the Trust and
         each respective Series as if the Series were separate companies.  There
         are,  however,  two exceptions to voting by separate Series.  First, if
         the  1940  Act  requires  all  Shares  of the  Trust to be voted in the
         aggregate without differentiation between the separate Series, then all
         Series  shall vote  together.  Second,  if any matter  affects only the
         interests of some but not all Series,  then only such  affected  Series
         shall be entitled to vote on the matter.

         equal  proportionate  interest in the assets  belonging  to that Series

         established by the Trustees.

         belonging  to any  two or  more  Series  into  assets  and  liabilities
         belonging to a single Series.

(i)      ELIMINATION OF SERIES. At any time that there are no Shares outstanding

SECTION 7.  INDEMNIFICATION OF SHAREHOLDERS

Shareholder   or  former   Shareholder   (or  his  or  her   heirs,   executors,
administrators,  or other legal  representatives or in the case of a corporation
or other entity, its corporate or other general successor) shall be entitled out
of the assets of the Trust to be held harmless from and indemnified  against all

SECTION 1.  NUMBER, ELECTION AND TENURE
The number of Trustees  shall be such number as shall be fixed from time to time
by a written instrument signed by a majority of the Trustees, provided, however,
that the number of  Trustees  shall in no event be less than three nor more than
15.  The  Trustees  may by vote of a majority  of the  remaining  Trustees  fill
vacancies in the Trustees or remove  Trustees with or without cause by vote of a
majority of the  Trustees  who are  "non-interested"  persons (as defined in the
1940 Act) if the Trustee to be removed is a "non-interested" Trustee, or by vote
of the Trustees who are "interested  persons" if the Trustee to be removed is an
"interested"  Trustee. Each Trustee shall serve during the continued lifetime of
the Trust until he dies,  resigns or is removed,  or, if sooner,  until the next
meeting of  Shareholders  called for the purpose of electing  Trustees and until
the election and qualification of his successor,  except,  that Trustees who are
not "interested  persons" or employees of American Century  Companies,  Inc. and
its affiliates  shall retire at the end of the calendar year in which they shall
have reached the age of seventy-five  (75) years.  Any Trustee may resign at any
time by written  instrument  signed by him and  delivered  to any officer of the
Trust or to a meeting of the Trustees.  Such resignation shall be effective upon
receipt  unless  specified  to be  effective  at some other time.  Except to the
extent  expressly  provided in a written  agreement  with the Trust,  no Trustee
resigning and no Trustee  removed shall have any right to any  compensation  for
any period  following  his  resignation  or removal,  or any right to damages on
account of such  removal.  The  Shareholders  may fix the number of Trustees and
elect  Trustees at any meeting of  Shareholders  called by the Trustees for that
purpose.


SECTION 2.  EFFECT OF DEATH, RESIGNATION, ETC. OF A TRUSTEE
The death, declination,  resignation,  retirement, removal, or incapacity of the
Trustees, or any of them, shall not operate to annual the Trust or to revoke any
existing  agency  created  pursuant to the terms of this  Declaration  of Trust.
Whenever a vacancy in the number of Trustees shall occur,  until such vacancy is
filled as provided in Article IV,  Section 1 the Trustees in office,  regardless
of their  number,  shall have all the powers  granted to the  Trustees and shall
discharge all the duties imposed upon the Trustees by this Declaration of Trust.
A written  instrument  certifying  the  existence  of such  vacancy  signed by a
majority of the Trustees  shall be conclusive  evidence of such vacancy.  In the
event of the death, declination, resignation, retirement, removal, or incapacity
of all  the  then  Trustees  within  a short  period  of time  and  without  the
opportunity  for at  least  one  disinterested  Trustee  being  able to  appoint
additional  Trustees  to fill  vacancies,  the  Trust's  investment  advisor  or
investment advisors jointly, if there is more than one, are empowered to appoint
new Trustees.


SECTION 3.  POWERS
Subject to the  provisions  of this  Declaration  of Trust,  the business of the
Trust shall be managed by the Trustees, and they shall have all powers necessary
or convenient to carry out that responsibility  including the power to engage in
securities  transactions of all kinds on behalf of the Trust.  Without  limiting
the  foregoing,  the  Trustees  may  adopt  Bylaws  not  inconsistent  with this
Declaration of Trust  providing for the regulation and management of the affairs

reserve that right to the Shareholders; they may fill vacancies in or reduce the
number of  Trustees,  and may elect and remove  such  officers  and  appoint and
terminate such agents as they consider appropriate;  they may appoint from their
own number and establish and terminate one or more committees  consisting of two
or more Trustees  which may exercise the powers and authority of the Trustees to
the extent that the Trustees  determine;  they may employ one or more custodians
of the  assets  of the  Trust  and  may  authorize  such  custodians  to  employ
subcustodians  and to  deposit  all or any part of such  assets  in a system  or

authority  as they  consider  desirable  to any  officer  of the  Trust,  to any
committee  of the  Trustees  and to any agent or employee of the Trust or to any
such  custodian,   transfer  or  Shareholder   servicing   agent,  or  principal
underwriter.  Any determination as to what is in the interests of the Trust made

                                    ARTICLE V
                    SHAREHOLDERS' VOTING POWERS AND MEETINGS

SECTION 1.  VOTING POWERS
Subject to the provisions of Article III, Section 6(d), the  Shareholders  shall
have power to vote only (i) for the  election of Trustees as provided in Article
IV,  Section  1, (ii) to the same  extent as the  stockholders  of a  California
business  corporation  as to whether or not a court action,  proceeding or claim
should or should not be brought or maintained  derivatively or as a class action
on  behalf  of  the  Trust  or  the  Shareholders,  (iii)  with  respect  to the
termination  of the Trust or any Series to the extent and as provided in Article
VIII,  Section 4, and (iv) with respect to such additional  matters  relating to
the Trust as may be required  by this  Declaration  of Trust,  the Bylaws or any
registration  of the Trust with the Commission (or any successor  agency) or any
state, or as the Trustees may consider necessary or desirable.  A Shareholder of
each Series shall be entitled to one vote for each dollar of net asset value per
Share of such  Series,  on any matter on which such  Shareholder  is entitled to
vote and each  fractional  dollar  amount  shall be entitled to a  proportionate
fractional  vote. All references in this Declaration of Trust or the Bylaws to a
vote of, or the holders of, a  percentage  of Shares shall mean a vote of or the
holders of that  percentage  of total  votes  representing  dollars of net asset
value of a  Series  or of the  Trust,  as the  case  may be.  There  shall be no
cumulative voting in the election of Trustees.  Shares may be voted in person or
by proxy. A proxy with respect to Shares held in the name of two or more persons
shall be valid if  executed by any one of them unless at or prior to exercise of
the proxy the Trust receives a specific  written notice to the contrary from any
one of them. A proxy  purporting to be executed by or on behalf of a Shareholder
shall be deemed  valid  unless  challenged  at or prior to its  exercise and the
burden of proving  invalidity shall rest on the challenger.  At any time when no
Shares of a Series are  outstanding,  the  Trustees  may  exercise all rights of
Shareholders of that Series with respect to matters affecting that Series,  take
any action required by law, this  Declaration of Trust or the Bylaws to be taken
by the Shareholders.


SECTION 2.  VOTING POWER AND MEETINGS
Meetings of the  Shareholders  may be called by the  Trustees for the purpose of
electing  Trustees  as  provided  in  Article  IV,  Section 1 and for such other
purposes as may be  prescribed  by law, by this  Declaration  of Trust or by the
Bylaws.  Meetings of the  Shareholders  may also be called by the Trustees  from
time to time for the purpose of taking  action upon any other  matter  deemed by
the Trustees to be necessary or desirable. A meeting of Shareholders may be held
at any place  designated  by the  Trustees.  Written  notice of any  meeting  of
Shareholders  shall be given or caused to be given by the  Trustees  by  mailing
such notice at least seven days before such meeting,  postage  prepaid,  stating
the time and place of the  meeting,  to each  Shareholder  at the  Shareholder's
address as it appears on the records of the Trust.  Whenever notice of a meeting
is required to be given to a Shareholder  under this Declaration of Trust or the
Bylaws,  a written waiver thereof,  executed before or after the meeting by such
Shareholder or his attorney  thereunto  authorized and filed with the records of
the meeting, shall be deemed equivalent to such notice.


SECTION 3.  QUORUM AND REQUIRED VOTE
Except when a larger quorum is required by  applicable  law, by the Bylaws or by
this  Declaration of Trust,  forty percent (40%) of the Shares  entitled to vote
shall  constitute  a quorum  at a  Shareholders'  meeting.  When any one or more
Series is to vote as a single class  separate from any other Shares which are to
vote on the same matters as a separate class or classes,  forty percent (40%) of
the Shares of each such Series  entitled to vote shall  constitute a quorum at a
Shareholders'  meeting  of that  Series.  Any  meeting  of  Shareholders  may be
adjourned  from time to time by a majority of the votes  properly  cast upon the
question,  whether or not a quorum is  present,  and the  meeting may be held as
adjourned  within a reasonable time after the date set for the original  meeting
without further notice.  Subject to the provisions of Article III, Section 6(d),
when a quorum is present at any  meeting,  a majority of the Shares  voted shall
decide any questions and a plurality shall elect a Trustee, except when a larger
vote is required by any provision of this  Declaration of Trust or the Bylaws or
by applicable law.


SECTION 4.  ACTION BY WRITTEN CONSENT
Any action taken by Shareholders  may be taken without a meeting if Shareholders
holding a majority of the Shares  entitled to vote on the matter (or such larger
proportion  thereof  as shall  be  required  by any  express  provision  of this
Declaration  of Trust or by the Bylaws)  and holding a majority  (or such larger
proportion as aforesaid) of the Shares of any Series entitled to vote separately
on the matter  consent to the action in writing and such  written  consents  are
filed with the records of the meetings of  Shareholders.  Such consent  shall be
treated for all purposes as a vote taken at a meeting of Shareholders.


SECTION 5.  RECORD DATES
For the purpose of determining  the  Shareholders of any Series who are entitled
to vote or act at any meeting or any adjournment  thereof, the Trustees may from
time to time fix a time, which shall be not more than 75 days before the date of
any meeting of Shareholders, as the record date for determining the Shareholders
of such Series having the right to notice of and to vote at such meeting and any
adjournment thereof, and in such case only Shareholders of record on such record
date shall have such right,  notwithstanding any transfer of shares on the books
of the  Trust  after  the  record  date.  For the  purpose  of  determining  the
Shareholders  of any Series who are entitled to receive  payment of any dividend
or of any other  distribution,  the  Trustees  may from time to time fix a date,
which  shall be before the date for the  payment of such  dividend or such other
payment,  as the record date for  determining  the  Shareholders  of such Series
having the right to receive  such  dividend or  distribution.  Without  fixing a
record date the Trustees may for voting and/or  distribution  purposes close the
register  or  transfer  books for one or more  Series for all or any part of the
period between a record date and a meeting of  Shareholders  or the payment of a
distribution.  Nothing in this  section  shall be construed  as  precluding  the
Trustees from setting different record dates for different Series.


SECTION 6.  ADDITIONAL PROVISIONS
The Bylaws may include further  provisions for Shareholders'  votes and meetings
and related matters.


                                   ARTICLE VI
                 NET ASSET VALUE, DISTRIBUTIONS, AND REDEMPTIONS

SECTION 1.  DETERMINATION OF NET ASSET VALUE, NET INCOME, AND DISTRIBUTIONS
Subject  to Article  III,  Section 6 hereof,  the  Trustees,  in their  absolute
discretion, may prescribe and shall set forth in the Bylaws or in a duly adopted
resolution of the Shares of any Series or net income  attributable to the Shares
of any Series,  or the declaration and payment of dividends and distributions on
the Shares of any Series, as they may deem necessary or desirable.


SECTION 2.  REDEMPTIONS AND REPURCHASES
The Trust  shall  purchase  such Shares as are  offered by any  Shareholder  for
redemption,  upon the presentation of a proper  instrument of transfer  together
with a request  directed to the Trust or a person  designated  by the Trust that
the Trust purchase such Shares or in accordance  with such other  procedures for
redemption as the Trustees may from time to time  authorize;  and the Trust will
pay therefor the net asset value thereof,  as determined in accordance  with the
Bylaws and applicable law, next determined  under the 1940 Act. Payment for said
Shares shall be made by the Trust to the Shareholder within seven days after the
date on which the request is made in proper form.  The  obligation  set forth in
this Section 2 is subject to the  provision  that in the event that any time the
New York Stock  Exchange is closed for other than  weekends or  holidays,  or if
permitted  by the rules of the  Commission,  during  periods when trading on the
Exchange is restricted or during any emergency which makes it impracticable  for
the Trust to dispose of the investments of the applicable Series or to determine
fairly the value of the net assets  belonging to such Series or during any other
period  permitted by order of the  Commission  for the  protection of investors,
such obligation may be suspended or postponed by the Trustees.


SECTION 3.  REDEMPTIONS AT THE OPTION OF THE TRUST
The Trust shall have the right at its option and at any time to redeem Shares of
any Shareholder at the net asset value thereof as described in Section 1 of this
Article  VI:  (i) if at such time such  Shareholder  owns  Shares of any  Series
having an  aggregate  net  asset  value of less  than an  amount,  not to exceed
$1,000, determined from time to time by the Trustees; or (ii) to the extent that
such  Shareholder  owns Shares equal to or in excess of a percentage  determined
from time to time by the Trustees of the  outstanding  Shares of the Trust or of
any Series.


                                   ARTICLE VII
              COMPENSATION AND LIMITATION OF LIABILITY OF TRUSTEES

SECTION 1.  COMPENSATION
The non-interested Trustees as such shall be entitled to reasonable compensation
from the Trust, and they may fix the amount of such compensation. Nothing herein
shall in any way prevent the employment of any Trustee for advisory, management,
legal, accounting, investment banking or other services and payment for the same
by the Trust.


SECTION 2.  LIMITATION OF LIABILITY
The Trustees  shall not be responsible or liable in any event for any neglect or
wrongdoing of any officer, agent, employee,  manager or Principal Underwriter of
the Trust,  nor shall any Trustee be responsible  for the act or omission of any
other Trustee,  but nothing herein  contained  shall protect any Trustee against
any  liability  to which he would  otherwise  be  subject  by  reason  of wilful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of his office.

Every note,  bond,  contract,  instrument,  certificate or undertaking and every
other act or thing  whatsoever  issued,  executed or done by or on behalf of the
Trust or the  Trustees  or any of them in  connection  with the  Trust  shall be
conclusively  deemed  to have  been  issued,  executed  or done  only in or with
respect to their or his  capacity as Trustees or Trustee,  and such  Trustees or
Trustee shall not be personally liable thereon.


SECTION 3.  INDEMNIFICATION
The Trustees shall be entitled and empowered to the fullest extent  permitted by
law to purchase  insurance for and to provide by resolution or in the Bylaws for
indemnification  out  of  Trust  assets  for  liability  and  for  all  expenses
reasonably  incurred  or paid or  expected to be paid by a Trustee or officer in
connection  with any  claim,  action,  suit or  proceeding  in which he  becomes
involved  by virtue of his  capacity  or former  capacity  with the  Trust.  The
provisions, including any exceptions and limitations concerning indemnification,
may be set forth in detail in the Bylaws or in a resolution of the Trustees.


                                  ARTICLE VIII
                                  MISCELLANEOUS

SECTION 1.  TRUSTEES, SHAREHOLDERS, ETC. NOT PERSONALLY LIABLE; NOTICE
All persons  extending  credit to,  contracting with or having any claim against
the Trust or any Series  shall look only to the assets of the Trust,  or, to the
extent  that the  liability  of the  Trust may have been  expressly  limited  by
contract to the assets of a particular  Series,  only to the assets belonging to
the  relevant  Series,  for payment  under such credit,  contract or claim;  and
neither the  Shareholders  nor the  Trustees,  nor any of the Trust's  officers,
employees or agents, whether past, present or future, shall be personally liable
therefor. Nothing in this Declaration of Trust shall protect any Trustee against
any  liability  to which such  Trustee  would  otherwise be subject by reason or
wilful  misfeasance,  bad faith,  gross negligence or reckless  disregard of the
duties involved in the conduct of the office of Trustee.

Every note,  bond,  contract,  instrument,  certificate or  undertaking  made or
issued on behalf of the Trust by the  Trustees,  by an  officer or  officers  or
otherwise  may include a notice that this  Declaration  of Trust is on file with
the Secretary of the Commonwealth of Massachusetts and may recite that the note,
bond, contract, instrument,  certificate, or undertaking was executed or made by
or on behalf of the Trust or by them as  Trustee  or  Trustees  or as officer or
officers or otherwise  and not  individually  and that the  obligations  of such
instrument are not binding upon any of them or the Shareholders individually but
are  binding  only upon the assets and  property of the Trust or upon the assets
belonging  to the Series for the benefit of which the  Trustees  have caused the
note,  bond,  contract  instrument,  certificate  or  undertaking  to be made or
issued, and may contain such further recital as he or they may deem appropriate,
but the  omission of any such  recital  shall not operate to bind any Trustee or
Trustees  or  officer  or  officers  or   Shareholders   or  any  other   person
individually.


SECTION 2.  TRUSTEE'S GOOD FAITH ACTION, EXPERT ADVICE, NO BOND OR SURETY
The exercise by the Trustees of their powers and discretions  hereunder shall be
binding upon everyone  interested.  A Trustee shall be liable for his own wilful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved  in the conduct of the office of Trustee,  and for  nothing  else,  and
shall not be liable for  errors of  judgment  or  mistakes  of fact or law.  The
Trustees may take advice of counsel or other experts with respect to the meaning
and operation of this  Declaration of Trust, and shall be under no liability for
any act or omission in accordance with such advice or for failing to follow such
advice.  The  Trustees  shall not be required to give any bond as such,  nor any
surety if a bond is required.


SECTION 3.  LIABILITY OF THIRD PERSONS DEALING WITH TRUSTEES
No  person  dealing  with the  Trustees  shall  be  bound  to make  any  inquiry
concerning the validity of any transaction made or to be made by the Trustees or
to see to the  application  of any payments made or property  transferred to the
Trust or upon its order.


SECTION 4.  TERMINATION OF TRUST OR SERIES
Unless  terminated  as  provided  herein,   the  Trust  shall  continue  without
limitation of time.  The Trust may be terminated at any time by vote of at least
two-thirds  (66-2/3%)  of the Shares of each  Series  entitled  to vote,  voting
separately by Series,  or by the Trustees by written notice to the Shareholders.
Any  Series  may be  terminated  at any  time  by vote  of at  least  two-thirds
(66-2/3%) of the Shares of that Series or by the  Trustees by written  notice to
the Shareholders of that Series.

Upon termination of the Trust (or any Series,  as the case may be), after paying
or  otherwise  providing  for  all  charges,  taxes,  expenses  and  liabilities
belonging,  severally, to each Series (or the applicable Series, as the case may
be), whether due or accrued or anticipated as may be determined by the Trustees,
the Trust shall,  in accordance  with such  procedures as the Trustees  consider
appropriate,  reduce the remaining assets belonging,  severally,  to each Series
(or the applicable Series, as the case may be), to distributable form in cash or
shares or other  securities,  or any  combination  thereof,  and  distribute the
proceeds belonging to each Series or the applicable Series, as the case may be),
to the Shareholders of that Series, as a Series, ratably according to the number
of  Shares  of that  Series  held by the  several  Shareholders  on the  date of
termination.


SECTION 5.  MERGER AND CONSOLIDATION
The  Trustees may cause the Trust or one or more of its Series to be merged into
or consolidated  with another Trust or company or the Shares  exchanged under or
pursuant to any state or Federal  statute,  if any, or  otherwise  to the extent
permitted  by law.  Such  merger  or  consolidation  or share  exchange  must be
authorized  by vote of a majority  of the  outstanding  Shares of the Trust as a
whole  or any  affected  Series,  as may be  applicable;  provided  that  in all
respects not  governed by statute or  applicable  law,  the Trustees  shall have
power to prescribe the procedure  necessary or  appropriate to accomplish a sale
of assets, merger or consolidation.


SECTION 6.  FILING OF COPIES, REFERENCES, HEADINGS
The original or a copy of this instrument and of each amendment  hereto shall be
kept at the office of the Trust where it may be inspected by any Shareholder.  A
copy of this instrument and of each amendment hereto shall be filed by the Trust
with the  Secretary  of the  Commonwealth  of  Massachusetts  and with any other
governmental office where such filing may from time to time be required.  Anyone
dealing with the Trust may rely on a  certificate  by an officer of the Trust as
to whether or not any such  amendments  have been made and as to any  matters in
connection with the Trust hereunder; and, with the same effect as if it were the
original,  may relay on a copy certified by an officer of the Trust to be a copy
of this  instrument,  or of any such  amendments.  In this instrument and in any
such  amendment,  references  to  this  instrument,  and  all  expressions  like
"herein,"  "hereof" and "hereunder," shall be deemed to refer to this instrument
as amended or affected by any such  amendments.  Headings are placed  herein for
convenience of reference only and shall not be taken as a part hereof or control
or  affect  the  meaning,  construction  or  effect  of  this  instrument.  This
instrument may be executed in any number of counterparts  each of which shall be
deemed an original.


SECTION 7.  APPLICABLE LAW
This  Agreement and  Declaration of Trust is created under and is to be governed
by and construed and  administered  according to the laws of the Commonwealth of
Massachusetts.  The Trust shall be of the type commonly  called a  Massachusetts
business  trust,  and without  limiting  the  provisions  hereof,  the Trust may
exercise all powers which are ordinarily exercised by such a trust.


SECTION 8.  AMENDMENTS
This Declaration of Trust may be amended at any time by an instrument in writing
signed by a majority of the then Trustees.


SECTION 9.  TRUST ONLY
It is the intention of the Trustees to create only the  relationship  of Trustee
and beneficiary  between the Trustees and each Shareholder from time to time. It
is not the  intention of the Trustees to create a general  partnership,  limited
partnership,  joint stock  association,  corporation,  bailment,  or any form of
legal relationship other than a trust. Nothing in this Agreement and Declaration
of Trust shall be construed to make the  Shareholders,  either by  themselves or
with the Trustees, partners or members of a joint stock association.


SECTION 10.  USE OF THE NAME "BENHAM" AND "AMERICAN CENTURY"
American Century Services  Corporation  ("ACSC") has consented to the use by the
Trust of the identifying  words or names "Benham" and "American  Century" in the
names of the Trust and/or its various Series.  Such consent is conditioned  upon
the  employment  of  ACSC,  its  successors  or any  affiliate  thereof,  as the
Advisor/Investment  Manager of the Trust. As between the Trust and itself,  ACSC
controls the use of the name of the Trust insofar as such name contains "Benham"
and/or  "American  Century".  The  name or  identifying  words  "Benham"  and/or
"American  Century" may be used from time to time in other  connections  and for
other purposes by ACSC or its affiliated entities. ACSC may require the Trust to
cease using "Benham" or "American Century" in the name of the Trust if the Trust
ceases to employ,  for any reason,  ACSC,  an  affiliate,  or any  successor  as
Advisor/Investment Manager of the Trust.


         IN WITNESS  WHEREOF,  a majority of the Trustees as aforesaid do hereto
set their hands this 9th day of March,  1998, as an amendment and restatement of
that Agreement and Declaration of Trust  originally  executed on the 17th day of
September, 1985.

Fund shall give the Administrative  Agent notice of each borrowing  hereunder as
provided in Section  4.5(a)  hereof.  Each borrowing must be in an amount as set
forth in Section 4.4 hereof.  Not later than 3:00 p.m. New York time on the date
specified  for each  borrowing  hereunder,  each Bank shall make  available  the
amount of the Loan or Loans to be made by it on such date to the  Administrative
Agent,  at any account  designated by the  Administrative  Agent, in immediately
available funds, for account of the relevant Fund. The amount so received by the
Administrative  Agent  shall,  subject  to the  terms  and  conditions  of  this
Agreement,  be made  available  to the  relevant  Fund for the  benefit  of such
Borrower by depositing the same, in immediately  available  funds, in an account
of the relevant Fund  designated by the relevant Fund and maintained  with Chase
at its principal office.

                  Section 2.3  Changes of Commitments.

                  (a)  The  aggregate   amount  of  the  Commitments   shall  be
automatically reduced to zero on the Commitment Termination Date.

                  (b) The Funds shall have the right at any time or from time to
time upon three Business  Days' notice (i) so long as no Loans are  outstanding,
to terminate the Commitments  and (ii) to reduce the aggregate  unused amount of
the  Commitments;  provided  that (x) the Funds  shall give  notice of each such
termination  or  reduction  as  provided in Section  4.5(b)  hereof and (y) each
partial  reduction shall be in an aggregate  amount at least equal to $5,000,000
(or a larger integral multiple of $1,000,000).

                  (c) The  Commitments  once  terminated  or reduced  may not be
reinstated.

                  Section  2.4  Commitment  Fee.  The  Funds  shall  pay  to the
Administrative  Agent for  account  of each Bank a  commitment  fee on the daily
average  unused  amount  of such  Bank's  Commitment,  for the  period  from and
including  the date  hereof to but not  including  the  earlier of the date such
Commitment  is terminated  and the  Commitment  Termination  Date, at a rate per
annum equal to 0.055%. Solely for the purpose of calculating the commitment fee,
Swing Line Loans will not be deemed a utilization  of the aggregate  Commitments
of all Banks. Accrued commitment fee shall be payable on each March 31, June 30,
September  30 and  December  31  (beginning  on the first of such dates to occur
after  the date  hereof)  and on the  earlier  of the date the  Commitments  are
terminated  and the Commitment  Termination  Date. The Funds shall allocate such
commitment fee among the Borrowers pro rata based on their  respective Net Asset
Values  as at the  respective  dates  on  which  such  commitment  fee is due or
otherwise not in violation of applicable law.

                  Section 2.5 Lending Offices. The Loans made by each Bank shall
be made and maintained at such Bank's Applicable Lending Office.

                  Section 2.6 Several  Obligations;  Remedies  Independent.  The
failure  of any Bank to make  any  Loan to be made by it on the  date  specified
therefor  shall not relieve any other Bank of its obligation to make its Loan on
such  date,  but  neither  any  Bank  nor  the  Administrative  Agent  shall  be
responsible  for the failure of any other Bank to make a Loan to be made by such
other  Bank,  and (except as  otherwise  provided in Section 4.6 hereof) no Bank
shall have any obligation to the Administrative  Agent or any other Bank for the
failure  by such Bank to make any Loan  required  to be made by such  Bank.  The
amounts  payable by the  Borrowers at any time  hereunder and under the Notes to
each Bank  shall be a  separate  and  independent  debt and each  Bank  shall be
entitled to protect and enforce its rights arising out of this Agreement and the
Notes  (subject,  in the case of the right to accelerate,  to Section 9 hereof),
and it shall not be necessary for any other Bank, or the Administrative Agent to
consent to, or be joined as an  additional  party in, any  proceedings  for such
purposes.

                  Section 2.7 Notes.

                  (a) Each Fund agrees that, upon the request of any Bank to the
Administrative  Agent,  each Fund will,  at such  Fund's  expense,  execute  and
deliver to such Bank a promissory note of each Borrower  evidencing the Loans of
such Bank to such  Borrower,  substantially  in the form if Exhibit  2.7(a) with
appropriate insertions as to date and principal amount (a "Note").

                  (b) The date and  amount  of each  Loan made by each Bank to a
Borrower,  and each payment made on account of the principal  thereof,  shall be
recorded by such Bank on its books and,  prior to any transfer of the applicable
Note,  endorsed  by  such  Bank on the  schedule  attached  to such  Note or any
continuation  thereof;  provided  that the failure of such Bank to make any such
recordation (or any error in making any such  recordation) or endorsement  shall
not  affect the  obligations  of a  Borrower  to make a payment  when due of any
amount  owing  hereunder  or under such Note in  respect of the Loans  evidenced
thereby.

                  (c) No Bank shall be entitled to have its Notes substituted or
exchanged  for  any  reason,  or  subdivided  for  promissory  notes  of  lesser
denominations,  except in connection  with a permitted  assignment of all or any
portion of such Bank's  Commitment,  Loans and Notes  pursuant  to Section  11.6
hereof  (and,  if  requested  by any Bank,  the Funds agree to so  exchange  any
Notes).

                  Section  2.8  Optional  Prepayments.  Subject to  Section  4.4
hereof, a Borrower shall have the right to prepay Loans at any time or from time
to time, provided that such Borrower shall give the Administrative  Agent notice
of each such prepayment as provided in Section 4.5(a) hereof (and, upon the date
specified  in any such  notice of  prepayment,  the amount to be  prepaid  shall
become due and payable hereunder).

                  Section 2.9 Mandatory  Prepayments.  If, at any time,  (i) the
Asset  Coverage  of any  Borrower  shall fall  below 300% or (ii) the  aggregate
amount of Loans made to a Borrower exceed the limits provided in such Borrower's
Prospectus,  then,  within three Business Days  thereafter,  such Borrower shall
prepay  Loans made to such  Borrower to the extent  necessary to ensure that (x)
the Asset Coverage is equal to or greater than 300% or (y) the aggregate  amount
of Loans made to such  Borrower  then  outstanding  does not after such payments
exceed such limits as set forth in such Borrower's  Prospectus or the Investment
Company Act, as the case may be.

                  Section 2.10 Extension of Commitment Termination Date.

                  (a) The  Funds  may,  by notice  to the  Administrative  Agent
(which shall promptly notify the Banks) given not less than 60 days and not more
the 90 days  prior  to the  Commitment  Termination  Date  then in  effect  (the
"Existing  Commitment  Termination  Date"),  request  that the Banks  extend the
Commitment  Termination  Date  for an  additional  364 days  from  the  Existing
Commitment Termination Date. Each Bank, acting in its sole discretion, shall, by
notice (which shall be  irrevocable) to the Funds and the  Administrative  Agent
given no earlier than the date that is 30 days prior to the Existing  Commitment
Termination Date (herein, the "Consent Date") and no later than the date that is
three Business Days after the Consent Date, advise the Funds whether or not such
Bank agrees to such  extension;  provided that each Bank that  determines not to
extend the Commitment Termination Date (a "Non-Extending Bank") shall notify the
Administrative  Agent (which shall notify the Banks) of such fact promptly after
such  determination (but in any event no later than the date three Business Days
after the Consent  Date) and any Bank that does not advise the Funds on or prior
to the date three  Business Days after the Consent Date that such Bank agrees to
such extension shall be deemed to be a  Non-Extending  Bank. The election of any
Bank to agree to such extension shall not obligate any other Bank to so agree.

                  (b) The Funds  shall have the right on or before the  Existing
Commitment  Termination  Date to request  that the  Administrative  Agent and/or
Chase,  in good  faith,  seek to  replace  each  Non-Extending  Bank  with,  and
otherwise add to this Agreement,  one or more other banks (which may include any
Bank,  each prior to the Existing  Commitment  Termination  Date, an "Additional
Commitment Bank"), each of which Additional  Commitment Banks shall have entered
into an  agreement  in form and  substance  satisfactory  to the  Funds  and the
Administrative  Agent pursuant to which such  Additional  Commitment Bank shall,
effective as of the Existing Commitment Termination Date, undertake a Commitment
specified  therein and otherwise  become  obligated as a Bank hereunder (and, if
any such Additional  Commitment Bank is already a Bank, its Commitment  shall be
in addition to such Bank's  Commitment  hereunder on such date). The Funds shall
also  have the  right to  replace  each  Non-Extending  Bank in the same  manner
described herein, except that any bank selected by the Funds must be approved by
the Administrative Agent (which approval shall not be unreasonably withheld).

                  (c) If (and only if) the total of the Commitments of the Banks
that have agreed so to extend the Commitment Termination Date and the additional
Commitments  of the  Additional  Commitment  Banks shall be at least 100% of the
aggregate amount of the Commitments in effect immediately prior to the date that
is three  Business  Days  after the  Consent  Date,  then,  effective  as of the
Existing Commitment  Termination Date, (i) the Existing  Commitment  Termination
Date  shall  be  extended  to the  date  falling  364 days  after  the  Existing
Commitment  Termination  Date (except  that, if such date is not a Business Day,
such  Commitment  Termination  Date as so extended  shall be the next  preceding
Business Day),  (ii) each Additional  Commitment  Bank shall thereupon  become a
"Bank" for all  purposes  of this  Agreement  and (iii) the  Commitment  of each
Non-Extending Bank shall terminate.

                  (d) Notwithstanding the foregoing clauses (a) through (c), the
extension of the  Existing  Commitment  Termination  Date shall not be effective
with respect to any Bank unless:

                           (i) no Default  shall have occurred and be continuing
         on each of the date of the notice  requesting  such  extension,  on the
         Consent Date and on the Existing Commitment Termination Date;

                           (ii) each of the  representations and warranties made
         by the  Funds  and  Borrowers  in  Section  7 hereof  shall be true and
         complete  on and as of each of the date of the notice  requesting  such
         extension,  the Consent  Date and the Existing  Commitment  Termination
         Date with the same  force and  effect as if made on and as of such date
         (or, if any such representation or warranty is expressly stated to have
         been made as of a specific date, as of such specific date); and

                           (iii) each Non-Extending Bank shall have been paid in
         full by the Funds all amounts due to such Bank  hereunder  on or before
         the Existing Termination Date.

                  Section 2.11 Designation of Additional Borrower; Amendments to
Schedule I.

                  (a) Other series of each Fund and other  investment  companies
registered  under the  Investment  Company Act, in either case (a) which have at
least  $2,000,000 in Total Assets,  (b) are (I) equity funds,  (II) fixed income
funds,  or (III) any  combination  thereof,  in each case  whether  investing in
domestic or foreign securities or any combination thereof, and (c) for which the
Investment  Adviser or an Investment  Adviser  Affiliate  acts as the investment
manager,  may, with the prior written  consent of the  Administrative  Agent and
each Bank,  become  parties to this  agreement  in addition  to those  Borrowers
listed in Schedule I, and be deemed Borrowers for all purposes of this Agreement
by executing an instrument  substantially  in the form of Exhibit  2.11(a) (with
such  changes  therein as may be  approved by the  Administrative  Agent and the
Banks),  which instrument shall (x) have attached to it a copy of this Agreement
(as the same may have been  amended)  with a revised  Schedule I reflecting  the
participation  of such  additional  series or  investment  company and any prior
revisions to Schedule I effected in accordance  with the terms hereof and (y) be
accompanied  by the  documents and  instruments  required to be delivered by the
Borrowers  pursuant  to  Section 6 hereof,  including,  without  limitation,  an
opinion of counsel for the Funds substantially in the form of Exhibit 6.1(b).

                  (b) No  series  of any  Fund or  investment  company  shall be
admitted as a party to this  Agreement as a Borrower  unless at the time of such
admission  and  after  giving  effect  thereto:   (i)  the  representations  and
warranties  set forth in Section 7 hereof shall be true and correct with respect
to such  Borrower;  (ii) such  Borrower  shall be in  compliance in all material
respects with all of the terms and provisions set forth herein on its part to be
observed or  performed  at the time of the  admission  and after  giving  effect
thereto; and (iii) no Default or Event of Default with respect to such Borrower,
nor any event which with the giving of notice or  expiration  of any  applicable
grace  period or both would  constitute  such a Default or Event of Default with
respect to such Borrower, shall have occurred and be continuing.

                  Section 2.12 Swing Line  Commitment.  Subject to the terms and
conditions hereof,  Chase (in such capacity,  the "Swing Line Lender") agrees to
make  available  to the  Borrowers a portion of the credit  otherwise  available
under the Commitments  from time to time by making swing line loans ("Swing Line
Loans") to the Borrowers in an aggregate  principal  amount not to exceed at any
one time outstanding the Swing Line Commitment  (notwithstanding  that the Swing
Line Loans outstanding at any time, when aggregated with the Swing Line Lender's
other outstanding Loans hereunder, may exceed the Swing Line Lender's Commitment
then in effect); provided,  however, that on the date of the making of any Swing
Line Loan and while any such Swing Line  Loans are  outstanding,  the sum of the
aggregate  principal amount of all outstanding  Loans and Swing Line Loans shall
not exceed the total Commitments. During the Commitment Period applicable to the
Borrower, the Borrower may use the Swing Line Commitment by borrowing,  repaying
and reborrowing, all in accordance with the terms and conditions hereof.

                  Section 2.13  Procedure for Swing Line  Borrowing.  Whenever a
Borrower  desires that the Swing Line Lender make Swing Line Loans under Section
2.12  hereof,  the  Borrower  shall  give  the  Swing  Line  Lender  irrevocable
telephonic notice confirmed promptly in writing (which telephonic notice must be
received by the Swing Line Lender not later than 3:00 P.M.,  New York City time,
on the proposed date  specified for such  borrowing),  specifying  the amount of
each requested  Swing Line Loan.  Each borrowing under the Swing Line Commitment
shall be in an amount  equal to $50,000 or an  integral  multiple  of $50,000 in
excess  thereof.  Not later  than 5:00  P.M.,  New York City  time,  on the date
specified in a notice by the Borrower in respect of Swing Line Loans,  the Swing
Line Lender shall make available to the Administrative  Agent for the account of
the Borrower at the office of the Administrative Agent specified in Section 11.2
hereof an amount in immediately available funds equal to the amount of the Swing
Line Loan to be made by the Swing Line  Lender.  The proceeds of such Swing Line
Loan will then be made available to the Borrower on such date specified for such
borrowing by the  Administrative  Agent transferring by wire to the custodian of
and for the account of the Borrower the aggregate of the amounts made  available
to the  Administrative  Agent by the Swing Line Lender in immediately  available
funds.

                  Section 2.14 Refunding of Swing Line Loans.

                  (a)  The  Swing  Line  Lender,  at any  time in its  sole  and
absolute  discretion  may,  and on the  seventh  day  (or if  such  day is not a
Business  Day,  the next  Business  Day) after the date of such  borrowing  with
respect to any Swing Line Loans to the Borrower shall, on behalf of the Borrower
(and the Borrower hereby irrevocably  directs the Swing Line Lender to so act on
its  behalf),  upon  notice  given by the Swing Line  Lender no later than 10:00
A.M., New York City time, on the relevant  refunding date,  request each Bank to
make,  and each Bank hereby agrees to make, a Loan to the Borrower,  at the rate
set forth in Section 3.2 hereof, in the pro rata amount  determined  pursuant to
Section 4.2. hereof equal to the amount of such Swing Line Loans of the Borrower
(the "Refunded  Swing Line Loans")  outstanding  on the date of such notice,  to
repay the  Swing  Line  Lender.  Each Bank  shall  make the  amount of such Loan
available  to the  administrative  Agent at its office set forth in Section 11.2
hereof in immediately  available  funds,  no later than 1:00 P.M., New York City
time,  on the  date  of  such  notice.  The  proceeds  of such  Loans  shall  be
distributed by the Administrative Agent to the Swing Line Lender and immediately
applied  by the Swing  Line  Lender  to repay the  Refunded  Swing  Line  Loans.
Effective  on the date such Loans are made,  the portion of the Swing Line Loans
so paid shall no longer be outstanding as Swing Line Loans.

                  (b) The  making of any  Swing  Line  Loan  hereunder  shall be
subject to the satisfaction of the applicable  conditions  precedent thereto set
forth in Section 6 hereof (unless  otherwise  waived in accordance  with Section
11.4 hereof).

                  (c) If prior to the making of a Loan to the Borrower  pursuant
to Section  2.14(a) hereof one of the events  described in Sections 9(f) or 9(g)
hereof shall have occurred with respect to the  Borrower,  each Bank  severally,
unconditionally  and  irrevocably  agrees that it shall purchase a participating
interest in the applicable Swing Line Loans  ("Unrefunded  Swing Line Loans") in
an amount equal to the amount of Loans which would  otherwise  have been made by
such Bank  pursuant  to  Section  2.14(a)  hereof.  Each  Bank will  immediately
transfer to the Administrative Agent, in immediately available funds, the amount
of its participation (the "Swing Line Participation  Amount"),  and the proceeds
of such participation  shall be distributed by the  Administrative  Agent to the
Swing Line Lender in such amount as will reduce the amount of the  participating
interest retained by the Swing Line in its Swing Line Loans to the amount of the
Loans which were to have been made by it pursuant to Section 2.14(a) hereof.

                  (d)  Whenever,  at any time  after the Swing  Line  Lender has
received from any Bank such Lender's Swing Line Participation  amount, the Swing
Line Lender  receives any payment on account of the Swing Line Loans,  the Swing
Line Lender will  distribute  to such Bank its Swing Line  Participation  Amount
(appropriately adjusted, in the case of interest payments, to reflect the period
of time during which such participating interest was outstanding and funded and,
in the case of principal and interest payments,  to reflect such Bank's pro rata
portion of such payment if such payment is not  sufficient  to pay the principal
of and interest on all Swing Line Loans then due);  provided,  however,  that in
the event that such payment  received by the Swing Line Lender is required to be
returned,  such Bank will return to the Swing Line  Lender any  portion  thereof
previously distributed to it by the Swing Line Lender.

                  (e) Each Bank's  obligation  to make the Loans  referred to in
Section  2.14(a)  hereof and to  purchase  participating  interests  pursuant to
Section  2.14(c)  hereof  shall be absolute and  unconditional  and shall not be
affected by any circumstance,  including,  without  limitation,  (i) any setoff,
counterclaim,  recoupment,  defense  or other  right  which  such  Bank may have
against  the Swing Line  Lender or any other  Person for any reason  whatsoever;
(ii) the  occurrence or  continuance  of a Default or an Event of Default or the
failure to satisfy any of the other  conditions  specified  in Section 6 hereof,
(iii) any  adverse  change in the  condition  (financial  or  otherwise)  of the
Borrower;  (iv) any breach of this  Agreement or any Note by the Borrower or the
Bank, or (v) any other circumstance,  happening or event whatsoever,  whether or
not similar to any of the foregoing.

Section 3.        Payments of Principal and Interest.

                  Section 3.1 Repayment of Loans. Each Borrower hereby severally
and  unconditionally,  but neither jointly nor jointly and severally promises to
pay to the  Administrative  Agent for account of each Bank the principal of each
Loan made by such Bank to such  Borrower,  and each Loan  shall  mature,  on the
earlier  of (a) the date that is 30  calendar  days after the date such Loan was
made and (b) the Commitment Termination Date.

                  Section 3.2  Interest.

                  (a)   Each   Borrower    hereby    promises    severally   and
unconditionally,  but neither  jointly nor jointly and severally,  to pay to the
Administrative  Agent for account of each Bank interest on the unpaid  principal
amount of each Loan (which, for purposes of this Section 3.2, shall include each
Swing  Line Loan) made by such Bank to such  Borrower,  for the period  from and
including  the date of such Loan to but  excluding  the date such Loan  shall be
paid in full,  at a rate equal to the Federal Funds Rate (as in effect from time
to time) plus the Applicable Margin.

                  (b)  Notwithstanding  the  foregoing,   each  Borrower  hereby
promises  to pay to the  Administrative  Agent  for the  account  of  each  Bank
interest at the Post-Default Rate on any principal of any Loan made by such Bank
to such Borrower and on any other amount  payable by such Borrower in respect of
such Loan  hereunder  or under the  applicable  Note held by such Bank to or for
account of such Bank, that shall not be paid to the Administrative Agent for the
benefit  of the  Banks  in  full  when  due  (whether  at  stated  maturity,  by
acceleration,  by mandatory  prepayment or  otherwise),  for the period from and
including  the due date  thereof to but  excluding  the date the same is paid in
full.

                  (c) Accrued  interest on each Loan shall be payable in arrears
upon the payment or prepayment thereof (but only on the principal amount so paid
or prepaid);  except that interest payable at the Post-Default  Rate pursuant to
Section  3.2(b)  hereof shall be payable  from time to time on demand.  Promptly
after the  determination  of any interest rate provided for herein or any change
therein, the Administrative Agent shall give notice thereof to the Banks.

Section 4.        Payments; Pro Rata Treatment; Computations; Etc.

                  Section 4.1 Payments.

                  (a)  Except  to the  extent  otherwise  provided  herein,  all
payments of principal, interest and other amounts to be made by a Borrower under
this Agreement and the Notes, shall be made in Dollars, in immediately available
funds, without deduction,  set-off or counterclaim,  to the Administrative Agent
(Account No.  323-525369,  or any other account designated by the Administrative
Agent), not later than 2:00 p.m. New York time on the date on which such payment
shall  become due (each such payment made after such time on such due date to be
deemed to have been made on the next succeeding  Business Day), provided that if
a new Loan to a Borrower is to be made by any Bank on a date such Borrower is to
repay any principal of an  outstanding  Loan made by such Bank to such Borrower,
such  Bank  shall  apply the  proceeds  of such new Loan to the  payment  of the
principal  to be repaid and only an amount equal to the  difference  between the
principal to be borrowed and the principal to be repaid shall be made  available
by such Bank to the  Administrative  Agent as  provided in Section 2.2 hereof or
paid by such Borrower to the Administrative  Agent pursuant to this Section 4.1,
as the case may be.

                  (b) Each  Borrower  shall,  at the time of making each payment
under this  Agreement  or any Note for the  account of any Bank,  specify to the
Administrative Agent (which shall so notify the intended  recipient(s)  thereof)
the  identity  of such  Borrower,  the Loans or other  amounts  payable  by such
Borrower hereunder to which such payment is to be applied (and in the event that
such Borrower fails to so specify, or if an Event of Default has occurred and is
continuing,  the Administrative Agent may distribute such payment for account of
such Borrower to the Banks for  application in such manner as it or the Majority
Banks, subject to Section 4.2 hereof, may determine to be appropriate).

                  (c) Each payment  received by the  Administrative  Agent under
this  Agreement  or any  Note  for  account  of any  Bank  shall  be paid by the
Administrative Agent promptly to such Bank, in immediately  available funds, for
account  of  such  Bank's  Applicable  Lending  Office  for the  Loan  or  other
obligation in respect of which such payment is made.

                  (d) If the due date of any payment under this Agreement or any
Note would  otherwise  fall on a day that is not a Business Day, such date shall
be extended to the next  succeeding  Business Day, and interest shall be payable
for any principal so extended for the period of such extension.

                  Section 4.2 Pro Rata Treatment. Except to the extent otherwise
provided herein:

                  (a) each  borrowing  from the Banks  under  Section 2.1 hereof
shall be made from the Banks,  each payment of commitment  fee under Section 2.4
hereof shall be made for account of the Banks, and each termination or reduction
of the amount of the  Commitments  under  Section 2.3 hereof shall be applied to
the respective  Commitments  of the Banks,  pro rata according to the amounts of
their respective Commitments;

                  (b) each  payment or  prepayment  of  principal  of Loans by a
Borrower shall be made for account of the Banks pro rata in accordance  with the
respective unpaid principal amounts of the Loans held by them; and

                  (c) each  payment of interest on Loans by a Borrower  shall be
made for  account  of the  Banks  pro rata in  accordance  with the  amounts  of
interest on such Loans then due and payable to the respective Banks.

                  Section 4.3       Computations.

                  (a) Interest on Loans and commitment fees shall be computed on
the basis of a 360-day  year for the  actual  days  elapsed.  Any  change in the
interest rate on a Loan  resulting from a change in the Federal Funds Rate shall
become  effective  as of the opening of business on the day on which such change
becomes effective.  The Administrative Agent shall as soon as practicable notify
the  Borrower  and the Banks of the  effective  date and the amount of each such
change in interest rate.

                  (b)   Each   determination   of  an   interest   rate  by  the
Administrative  Agent  pursuant  to any  provision  of this  Agreement  shall be
conclusive and binding on each Borrower and the Banks in the absence of manifest
error. The Administrative Agent shall, at the request of a Borrower,  deliver to
such  Borrower a statement  showing the  quotations  used by the  Administrative
Agent in determining any interest rate pursuant to Section 3.2 hereof.

                  Section 4.4 Minimum  Amounts.  Each  borrowing  shall be in an
aggregate  amount at least equal to $500,000  or a larger  integral  multiple of
$100,000. Each partial prepayment of principal of Loans shall be in an aggregate
amount at least equal to $100,000 or a larger integral multiple of $100,000.

                  Section 4.5 Certain Notices.

                  (a)  Notices  by a  Borrower  to the  Administrative  Agent of
borrowings and optional  prepayments of Loans shall be irrevocable  and shall be
effective only if received by the Administrative Agent not later than 12:00 noon
New York time on the date of the  relevant  borrowing or  prepayment.  Each such
notice of borrowing or optional  prepayment shall specify the Borrower for whose
benefit such  borrowing  or  prepayment,  or on whose  behalf such  borrowing or
prepayment  is to be made,  the Loans to be  borrowed  or prepaid and the amount
(subject  to Section  4.4 hereof) of each Loan to be borrowed or prepaid and the
date of borrowing or optional prepayment (which shall be a Business Day).

                  (b)  Notices  by a  Borrower  to the  Administrative  Agent of
terminations or reductions of the Commitments  shall be irrevocable and shall be
effective  only if received in a timely  manner,  as set forth in Section 2.3(b)
hereof,  by the  Administrative  Agent.  Each  such  notice  of  termination  or
reduction  shall  specify  the amount of the  Commitments  to be  terminated  or
reduced.

                  (c) The  Administrative  Agent shall promptly notify the Banks
of the contents of each such notice.

                  Section 4.6 Non-Receipt of Funds by the Administrative  Agent.
Unless the Administrative Agent shall have been notified by a Bank or a Borrower
(the  "Payor")  prior to the date on which the Payor is to make  payment  to the
Administrative  Agent of (in the case of a Bank)  the  proceeds  of a Loan to be
made by such Bank  hereunder  or (in the case of a  Borrower)  a payment  to the
Administrative  Agent for  account of one or more of the Banks  hereunder  (such
payment  being  herein  called the  "Required  Payment"),  which notice shall be
effective  upon  receipt,  that the Payor does not  intend to make the  Required
Payment to the Administrative  Agent, the  Administrative  Agent may assume that
the  Required  Payment has been made and may, in reliance  upon such  assumption
(but  shall not be  required  to),  make the  amount  thereof  available  to the
intended  recipient(s)  on such date; and, if the Payor has not in fact made the
Required Payment to the  Administrative  Agent, the recipient(s) of such payment
shall, on demand, repay to the Administrative Agent the amount so made available
together with interest  thereon (such interest to be, in the case of a Bank, the
Federal  Funds  Rate and,  in the case of a  Borrower,  as set forth in  Section
3.2(a)  hereof) in respect of each day during the period  commencing on the date
(the  "Advance  Date") such amount was so made  available by the  Administrative
Agent until the date the Administrative Agent recovers such amount at a rate per
annum  equal to the Federal  Funds Rate for such day and,  if such  recipient(s)
shall fail  promptly to make such  payment,  the  Administrative  Agent shall be
entitled  to recover  such  amount,  on demand,  from the Payor,  together  with
interest as aforesaid,  provided that if neither the  recipient(s) nor the Payor
shall  return the  Required  Payment to the  Administrative  Agent  within three
Business Days of the Advance Date, then,  retroactively to the Advance Date, the
Payor and the  recipient(s)  shall  each be  obligated  to pay  interest  on the
Required Payment as follows:

                  (a) if the Required  Payment  shall  represent a payment to be
made by a Borrower to the Banks,  such Borrower and the recipient(s)  shall each
be obligated retroactively to the Advance Date to pay interest in respect of the
Required Payment at the Post-Default Rate (without duplication of the obligation
of such  Borrower  under  Section  3.2 hereof to pay  interest  on the  Required
Payment at the  Post-Default  Rate), it being  understood that the return by the
recipient(s) of the Required Payment to the Administrative Agent shall not limit
such  obligation of such Borrower  under said Section 3.2 to pay interest at the
Post-Default Rate in respect of the Required Payment; and

                  (b) if the Required Payment shall represent proceeds of a Loan
to be made by the Banks to a Borrower, such Borrower and the Payor shall each be
obligated  retroactively  to the Advance  Date to pay interest in respect of the
Required  Payment  pursuant to the rate specified in Section 3.2 hereof (without
duplication  of the  obligation of such Borrower under Section 3.2 hereof to pay
interest on the Required  Payment),  it being understood that the return by such
Borrower of the Required Payment to the Administrative Agent shall not limit any
claim such  Borrower  may have  against  the Payor in  respect of such  Required
Payment.

                  Section 4.7 Sharing of Payments, Etc.

                  (a)  Each  Fund  agrees  that,  in  addition  to (and  without
limitation  of) any right of set-off,  banker's lien or  counterclaim a Bank may
otherwise  have,  each Bank shall be  entitled,  at its  option (to the  fullest
extent  permitted by law), to set off and apply any deposit (general or special,
time or demand, provisional or final), or other indebtedness, held by it for the
credit or  account  of a Borrower  at any of its  offices,  in Dollars or in any
other currency, against any principal of or interest on any of such Bank's Loans
to such  Borrower  or any other  amount  payable by such  Borrower  to such Bank
hereunder,  that is not paid when due  (regardless  of whether  such  deposit or
other  indebtedness  are then  due to such  Borrower),  in  which  case it shall
promptly  notify such Borrower and the  Administrative  Agent thereof,  provided
that such  Bank's  failure to give such  notice  shall not  affect the  validity
thereof.

                  (b) If any Bank shall  obtain  from a Borrower  payment of any
principal  of or interest on any Loan owing to it or payment of any other amount
under this Agreement through the exercise of any right of set-off, banker's lien
or   counterclaim   or  similar   right  or  otherwise   (other  than  from  the
Administrative Agent as provided herein), and, as a result of such payment, such
Bank shall have received a greater percentage of the principal of or Interest on
the Loans  made to such  Borrower  or such other  amounts  then due to such Bank
hereunder by such  Borrower than the  percentage  received by any other Bank, it
shall promptly  purchase from such other Banks  participations in (or, if and to
the extent specified by such Bank, direct interests in) such Loans or such other
amounts, respectively, owing to such other Banks (or in interest due thereon, as
the case may be) in such amounts,  and make such other  adjustments from time to
time as  shall be  equitable,  to the end that all the  Banks  shall  share  the
benefit of such excess payment (net of any expenses that may be incurred by such
Bank in obtaining or preserving such excess payment) pro rata in accordance with
the unpaid  principal  of and/or  interest on such Loans or such other  amounts,
respectively,  owing to each of the Banks.  To such end all the Banks shall make
appropriate  adjustments among themselves (by the resale of participations  sold
or otherwise) if such payment is rescinded or must otherwise be restored.

                  (c)  Each  Fund  agrees  that any  Bank so  purchasing  such a
participation (or direct interest) may exercise all rights of set-off,  banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Bank were a direct  holder of Loans or other amounts (as the case may
be) owing to such Bank in the amount of such participation (or direct interest).

                  (d)  Nothing  contained  herein  shall  require  any  Bank  to
exercise any such right or shall  affect the right of any Bank to exercise,  and
retain the  benefits  of  exercising,  any such right with  respect to any other
indebtedness or obligation of a Borrower.  If, under any applicable  bankruptcy,
insolvency  or other similar law, any Bank receives a secured claim in lieu of a
set-off  to which this  Section  4.7  applies,  such Bank  shall,  to the extent
practicable,  exercise its rights in respect of such  secured  claim in a manner
consistent with the rights of the Banks entitled under this Section 4.7 to share
in the benefits of any recovery on such secured claim.

                  Section 4.8 Requirements of Law.

                  (a) If any Bank shall have  determined that the adoption of or
any change in any  applicable  law,  rule, or  regulation,  or any change in any
applicable  law,  rule or  regulation,  or any change in the  interpretation  or
administration  thereof  by  any  governmental   authority,   central  bank,  or
comparable agency charged with the interpretation or administration  thereof, or
compliance  by such  Bank or any  corporation  controlling  such  Bank  with any
request or directive regarding capital adequacy (whether or not having the force
of law) from any such  authority,  central bank, or  comparable  authority  made
subsequent  to the date  hereof  shall have the effect of  reducing  the rate of
return on such  Bank's or such  corporation's  capital as a  consequence  of its
obligations  hereunder to a level below that which such Bank or such corporation
could have achieved but for such adoption,  change,  or compliance  (taking into
consideration such Bank's or such corporation's policies with respect to capital
adequacy) by an amount determined by such Bank, in its reasonable discretion, to
be material,  then from time to time,  each Borrower  shall promptly pay to such
Bank such  additional  amount or amounts as will  compensate  such Bank for such
reduction.

                  (b) If any  Bank  becomes  entitled  to claim  any  additional
amounts  pursuant to this Section 4.8, it shall  promptly  notify the  Borrowers
(with a copy to the Administrative Agent) of the event by reason of which it has
become so entitled by providing a certificate setting forth in reasonable detail
the basis for the claim for additional amounts,  the amounts required to be paid
by the  Borrowers  to such  Bank,  and  the  computations  made by such  Bank to
determine the amounts; provided that such Bank shall not be required to disclose
any  confidential  information.  Such  certificate as to any additional  amounts
payable  pursuant to this Section 4.8(b) submitted by such Bank to the Borrowers
(with a copy to the Administrative  Agent) shall be conclusive in the absence of
manifest error. The agreements in this Section 4.8 shall survive the termination
of this  Agreement  and the payment of the Loans and all other  amounts  payable
hereunder.  No  Borrower  shall  be  responsible  to  compensate  such  Bank for
additional amounts attributable to another Borrower's Loans.

                  (c)  Failure  or  delay  on the  part of any  Bank  to  demand
compensation  pursuant to this Section 4.8 shall not constitute a waiver of such
Bank's right to demand such compensation;  provided that the Borrowers shall not
be required to  compensate a Bank pursuant to this Section 4.8 for any increased
costs or reductions incurred more than 270 days prior to the date that such Bank
notifies the Borrower of the change in the  applicable  law, rule, or regulation
giving rise to such increased  costs or reductions and of such Bank's  intention
to claim  compensation  therefore;  provided  further that, if the change in the
applicable  law,  rule, or  regulation  giving rise to such  increased  costs or
reductions is  retroactive,  then the 270-day period  referred to above shall be
extended to include the period of retroactive effect thereof.

Section 5.        U.S. Taxes.

                  (a) All payments made by any Borrower  under this Agreement or
any Note shall be made free and clear of, and without  deduction or  withholding
for or on  account  of,  any  present or future  income,  stamp or other  taxes,
levies,  imposts,  duties,  charges,  fees,  deductions or withholdings,  now or
hereafter imposed, levied,  collected,  withheld or assessed by any Governmental
Authority,  excluding all present and future  income taxes and  franchise  taxes
(imposed in lieu of net income taxes) imposed on the Administrative Agent or any
Bank as a result of a present or former  connection  between the  Administrative
Agent or such Bank and the jurisdiction of the Governmental  Authority  imposing
such tax or any political  subdivision  or taxing  authority  thereof or therein
(other than any such connection arising solely from the Administrative  Agent or
such Bank having executed,  delivered or performed its obligations or received a
payment  under,  or  enforced,   this  Agreement  or  any  Note).  If  any  such
non-excluded  taxes,  levies,  imposts,  duties,  charges,  fees,  deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Administrative Agent or any Bank hereunder or under any Note, the
amounts so payable to the  Administrative  Agent or such Bank shall be increased
to the extent necessary to yield to the Administrative Agent or such Bank (after
payment of all  Non-Excluded  Taxes)  interest or any such other amounts payable
hereunder at the rates or in the amounts specified on this Agreement,  provided,
however,  that a Borrower  shall not be required to  increase  any such  amounts
payable to any Bank that is not organized  under the laws of the U.S. or a state
thereof if such Bank fails to comply with the  requirements  of paragraph (b) of
this  Section.  Whenever any  Non-Excluded  Taxes are payable by a Borrower,  as
promptly as possible thereafter,  such Borrower shall send to the Administrative
Agent for its own account or for the account of such Bank, as the case may be, a
certified copy of an original official receipt received by such Borrower showing
payment thereof.  If a Borrower fails to pay any Non-Excluded  Taxes when due to
the appropriate taxing authority or fails to remit to the  Administrative  agent
the required  receipts or other  required  documentary  evidence,  such Borrower
shall  indemnify  the  Administrative  Agent and the  Banks for any  incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Bank as a result of any such  failure.  The  agreements  in this  Section
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

                  (b) Each Bank that is not  incorporated  under the laws of the
U.S. or a state thereof shall:

                           (i)  deliver  to  the  Investment   Adviser  and  the
         Administrative  Agent (A) two duly  completed  copies of U.S.  Internal
         Revenue Service Form 1001 or 4224, or successor applicable form, as the
         case may be, and (B) and Internal  Revenue  Service From W-8 or W-9, or
         successor applicable form, as the case may be;

                           (ii)  deliver  to  the  Investment  Adviser  and  the
         Administrative   Agent  two   further   copies  of  any  such  form  or
         certification on or before the date that any such form or certification
         expires  or  becomes  obsolete  and after the  occurrence  of any event
         requiring a change in the most recent form  previously  delivered by it
         to the Investment Adviser; and

                           (iii) obtain such  extensions  of time for filing and
         complete such forms or certifications as may reasonably be requested by
         the Investment Adviser or the Administrative Agent;

unless in any such case an event (including,  without limitation,  any change in
treaty,  law or  regulation)  has  occurred  prior to the date on which any such
delivery would  otherwise be required which renders all such forms  inapplicable
or which would prevent such Bank from duly  completing  and  delivering any such
form with respect to it and such Bank so advises the Investment  Adviser and the
Administrative  Agent. Such Bank shall certify (A) in the case of a Form 1001 or
4224,  that it is  entitled to receive  payments  under this  Agreement  without
deduction or withholding of any U.S. federal income taxes and (B) in the case of
a Form  W-8 or  W-9,  that it is  entitled  to an  exemption  from  U.S.  backup
withholding  tax.  Each  Person  that  shall  be  subject  to an  assignment  or
participation  pursuant to Section 11.6 hereof shall,  upon the effectiveness of
the related  transfer,  be  required to provide all of the forms and  statements
required  pursuant  to this  Section  5,  provided  that in the case of a Person
subject to a  participation,  such Person shall  furnish all required  forms and
statements  to the Bank from  which the  related  participation  shall have been
purchased.

                  (c) If any Bank shall receive a credit or refund from a taxing
authority  with  respect  to,  and  actually   resulting   from,  an  amount  of
Non-Excluded  Taxes  actually paid to or on behalf of such Bank by a Borrower (a
"Tax  Credit"),  such Bank shall  promptly  pay to such  Borrower  the amount so
received  with respect to the Tax Credit.  If such Tax Credit is not received by
such Bank in the form of cash, such Bank shall pay the amount of such Tax Credit
not later  than the time  prescribed  by  applicable  law for  filing the return
(including extensions of time) for such Bank's taxable period which includes the
period in which such Bank receives the economic  benefit of such Tax Credit.  In
any event, the amount of any Tax Credit payable by a Bank to a Borrower pursuant
to this clause (c) shall not exceed the actual  amount of cash  refunded  to, or
credits received and usable (in accordance with the actual practices then in use
by such Bank) by, such Bank from a taxing  authority.  In determining the amount
of any Tax Credit, a Bank may use such  apportionments  and attribution rules as
such bank customarily  employs in allocating taxes among its various  operations
and income sources and such  determination  shall be conclusive  absent manifest
error. Each Borrower further agrees promptly to return to a Bank the amount paid
to such  Borrower  with  respect  to a Tax  Credit  by such Bank if such Bank is
caused to repay,  or is determined  to be ineligible  for, a Tax Credit for such
amount. Notwithstanding anything to the contrary contained herein, each Borrower
hereby acknowledges and agrees that (i) neither the Administrative Agent nor any
Bank  shall be  obligated  to  provide  such  Borrower  with  details of the tax
position of the Administrative  Agent or such Bank (as the case may be) and (ii)
such Borrower shall have no right to inspect any records (including tax returns)
of the Administrative Agent or such Bank (as the case may be).

Section 6.        Conditions Precedent.

                  Section 6.1 Initial Loan.  The  obligation of any Bank to make
its  initial  Loan  hereunder  is subject  to the  conditions  precedent  (which
conditions precedent apply to and shall be satisfied by the Borrowers severally)
that the Administrative Agent shall have received the following documents (with,
in  the  case  of  clauses  (a),  (b),  (c),  (d),  and  (e)  below,  sufficient
counterparts or copies,  as the case may be, for each Bank), each of which shall
be satisfactory to the Administrative  Agent (and to the extent specified below,

annual  and  semi-annual  financial  reports  for each  Borrower  and such other
documents or  instruments as may be reasonably  requested by the  Administrative
Agent, including,  without limitation,  a copy of any debt instrument,  security

                  (b) Corporate  Documents.  Certified copies of the charter and
by-laws (or  equivalent  documents) of each Fund and of all corporate  authority
for each Fund (including,  without  limitation,  board of director  resolutions)
with respect to the  execution,  delivery and  performance of this Agreement and
the Notes and each other document to be delivered by each Fund from time to time
in connection herewith and the Loans hereunder (and the Administrative Agent and
each Bank may conclusively  rely on such certificate until it receives notice in
writing from each Fund to the contrary).

                  (c) Incumbency Certificate.  A certificate of each Fund, dated
the Closing  Date,  as to the  incumbency  and signature of the officers of such
Fund  executing  this  Agreement or any Notes  executed by the  Secretary or any

Administrative Agent.

                  (d)  Opinion of Counsel to the Funds.  An  opinion,  dated the
date hereof, of Charles C.S. Park, Assistant General Counsel of American Century
Investment   Management,   Inc.,   counsel  to  the  Funds  and  each  Borrower,
substantially  in the form of Exhibit  6.1(b)  (and the Funds and each  Borrower
hereby  instruct  such  counsel  to  deliver  such  opinion to the Banks and the
Administrative Agent).

                  (e) Credit  Agreement.  Executed  copies of this Agreement and
all related  documents in form and  substance  reasonably  satisfactory  to each

                  (f) Notes. If requested pursuant to Section 2.7(a) hereof, the
Notes, duly completed and executed for each Bank.

                  (g)   Other   Documents.   Such   other   documents   as   the
Administrative  Agent  or any Bank or  special  New York  counsel  to Chase  may
reasonably request.

The obligation of any Bank to make its initial Loan hereunder is also subject to
the  payment by the Funds of such fees as the Funds  shall have agreed to pay or
deliver  to any  Bank  or  the  Administrative  Agent  in  connection  herewith,
including, without limitation, the reasonable fees and expenses of Dechert Price
& Rhoads, special New York counsel to Chase, in connection with the negotiation,
preparation,  execution  and  delivery of this  Agreement  and the Notes and the
making of the Loans  hereunder (to the extent that  statements for such fees and
expenses have been  delivered to the Funds).  The Funds shall allocate such fees
and expenses  among the Borrowers  pro rata  according to their  respective  Net
Asset  Values  as at the  date on  which  such  fees  and  expenses  are paid or
otherwise in compliance with law.

                  Section 6.2 Initial and  Subsequent  Loans.  The obligation of
the Banks to make any Loan to a Borrower  upon the  occasion  of each  borrowing
hereunder (including the initial borrowing) is subject to the further conditions
precedent that both immediately  prior to the making of such Loan and also after
giving effect thereto and to the intended use thereof:

                  (a) no Default shall have occurred and be continuing;

                  (b) the  representations  and warranties  made by each Fund on
behalf  of  itself  and each  Borrower  in  Section  7 hereof  shall be true and
complete  on and as of the date of the  making of such Loan with the same  force
and effect as if made on and as of such date (or, if any such  representation or
warranty is expressly  stated to have been made as of a specific date as of such
specific date);

                  (c) the Banks shall be satisfied that the Loans and the use of
proceeds  thereof  in  respect  of each  Borrower  comply in all  respects  with
Regulation U. To the extent required by Regulation U, the  Administrative  Agent
shall  have  received  a copy of  either  (i) FR Form  U-1,  duly  executed  and
delivered by each Fund on behalf of each  Borrower and completed for delivery to
each Bank, in form  acceptable to the  Administrative  Agent,  or (ii) a current
list of "margin stock" (as defined in Regulation U) from each Borrower,  in form
acceptable  to  the   Administrative   Agent  and  in  compliance  with  Section
221.3(c)(2) of Regulation U; and

                  (d) (i) Asset  Coverage  of at least 300% of any  Borrower  as
provided by and in accordance  with the  Investment  Company Act (provided  that
"total  assets," as used in the  Investment  Company Act,  shall not include any
encumbered  assets of a Borrower) and (ii) borrowing  limits in such  Borrower's
Prospectus are not exceeded.

Each notice of borrowing  by a Fund on behalf of itself or a Borrower  hereunder
shall  constitute  a  certification  by such Fund to the effect set forth in the
preceding  sentence  (both as of the date of such notice  and,  unless such Fund
otherwise notifies the Administrative Agent prior to the date of such borrowing,
as of the date of such borrowing).

Section 7.        Representations and Warranties.

                  Each  Fund,  on  behalf of itself  and each  Borrower,  hereby
represents and warrants to the Administrative Agent and the Banks that (it being
agreed that each Fund  represents  and warrants  only to matters with respect to
itself  and  each  Borrower  that is a part  of such  Fund,  and  each  Borrower
represents only to matters with respect to itself):

                  Section 7.1  Corporate  Existence;  Compliance  with Law. Each
Fund: (a) is a corporation duly organized, validly existing and in good standing

                  (a) Each  Fund is  registered  with the  Commission  under the
Investment  Company Act as an open-end  management  investment  company,  and no
order of  suspension  or  revocation  of such  registration  has been  issued or
proceedings therefor initiated or threatened by the Commission.

                  (b)  Each  Borrower  is in  substantial  compliance  with  all
investment  objectives,  policies,  restrictions  and  limitations  set forth or
incorporated by reference in the Prospectus and applicable to such Borrower.

                  (c) The Investment  Adviser is the primary  investment adviser
to each  Borrower  and  Fund  and,  to the  best  knowledge  of each  Fund,  the
Investment  Adviser  is duly  registered  as an  investment  adviser  under  the
Advisers Act.

                  Section 7.3  Permission to Borrow.  Each Borrower is permitted
to borrow  hereunder  pursuant to the limits and  restrictions  set forth in its

material  agreement or instrument to which any Fund is a party or by which it or

power, authority and legal right to execute, deliver and perform its obligations
under  this  Agreement  and the Notes and to borrow  hereunder;  the  execution,

similar laws of general  applicability  affecting the  enforcement of creditors'

governmental  charges  are, in the opinion of each Fund,  adequate.  No Fund has
given or been requested to give a waiver of the statute of limitations  relating

impositions.

                  Section 7.13 True and Complete Disclosure.  No Prospectus,  as
of the date thereof,  contains any untrue statement of material fact or omits to
state any material fact  necessary to make the statements  therein,  in light of
the circumstances under which they were made, not misleading.  Since the date of

supplement or amend its Prospectus.

                  Section 7.14 Accuracy of Information.  All factual information
heretofore or contemporaneously  furnished by or on behalf of each Fund and each
Borrower in writing to the  Administrative  Agent or any Bank for purposes of or
in connection  with this Agreement or any  transaction  contemplated  hereby (in

knowledge  of the  Administrative  Agent or such  Bank) is,  and all other  such
factual  information  hereafter  furnished by or on behalf of each Fund and each
Borrower  to the  Administrative  Agent or any Bank (in each case,  as  amended,
superseded,  supplemented  or  otherwise  modified  with  the  knowledge  of the
Administrative  Agent or such Bank) will be, true and accurate in every material
respect on the date as of which such  information is dated or certified,  and to
the extent such  information was furnished to the  Administrative  Agent or such
Bank heretofore or  contemporaneously,  as of the date of execution and delivery
of this Agreement by the Administrative Agent or such Bank, and such information
is not, or shall not be, as the case may be, incomplete by omitting to state any
material fact necessary to make such information not misleading.

Fund nor any Borrower has any  Indebtedness  other than (a) current  liabilities

will furnish to the  Administrative  Agent and each Bank a statement and current
list of the assets of each Borrower in conformity  with the  requirements  of FR
Form U-1 referred to in said  Regulation  U. Other than the  furnishing  of such
statement  and such  list,  no filing  or other  action  is  required  under the
provision of Regulations T, U or X in connection with the execution and delivery
of the Agreement and the making of the Loans hereunder.

                  Section 7.19 Apportionment Among Funds. Borrowings of Loans by
a Fund for the benefit of any Borrower  will be allocated by such Fund among the
Borrowers on a fair and equitable  basis not in violation of applicable  law and
in  accordance  with  the  procedures  established  prior  to the  date  of this
Agreement  by the board of  directors  of the Fund,  as such  procedures  may be
amended from time to time.

                  Section 7.20 No Material  Adverse  Change.  For each Borrower,
since the date of the statement of assets and  liabilities for the most recently
ended fiscal year for which annual reports have been prepared for such Borrower,
there has been no  development  or event  which has had or could  reasonably  be
expected to have a Material Adverse Effect with respect to such Borrower.

project plan and is taking  appropriate steps to address the risk that, from and
after January 1, 2000, the computer system utilized by the Borrowers,  or by the
Funds on the Borrower's  behalf,  and the computer  systems of others with which
the Investment  Adviser's  computer  systems  interface may be unable to process
properly and calculate  date-related  information  and data,  and may experience
date-logic  failures  (such risk being the "Year 2000  Problem").  Each Borrower
reasonably expects that the Investment Adviser shall have performed any required
reprogramming  and testing of hardware and software  systems to resolve the Year
2000 Problem on or before June 30, 1999. Each Borrower  reasonably  expects that
the  effects  of the Year 2000  Problem  should  not  result  in a Default  or a
Material Adverse Effect.

                  Each Fund for  itself  and each  Borrower  for  itself  hereby

proceedings  and reserves in conformity with GAAP with respect thereto have been
provided on the books of such Borrower,  as the case may be, or (ii) the lack of

during such appeal; or

                  (i) Except as expressly  permitted by Section 8.7 hereof,  any
Person, or related Persons  constituting a "group" for purposes of Section 13(d)
of the  Securities  Exchange  Act of 1934,  as amended,  (other than a Specified

Material Adverse Effect; or

                  (m) A  Borrower  shall  fail to  comply  with  its  investment
policies and restrictions as set forth in its Prospectus in a manner which could

                  (o) since the date of the statement of assets and  liabilities

such Borrower;

THEREUPON:  (i) in the case of an Event of Default other than one referred to in
clause  (f)  or  (g)  of  this  Section  9  with  respect  to  a  Borrower,  the
Administrative  Agent may and,  upon request of the  Majority  Banks,  will,  by
notice to such Borrower,  terminate the Commitments and/or declare the principal
amount then outstanding of, and the accrued interest on, the Loans and all other
amounts  payable by such Borrower  hereunder and under the Notes to be forthwith
due and payable,  whereupon  such amounts shall be  immediately  due and payable
without  presentment,  demand,  protest or other formalities of any kind, all of
which are hereby expressly waived by such Borrower;  and (ii) in the case of the
occurrence  of an Event of  Default  referred  to in  clause  (f) or (g) of this
Section 9 with respect to a Borrower,  the Commitments  shall  automatically  be
terminated  and the  principal  amount  then  outstanding  of,  and the  accrued
interest on, the Loans and all other amounts payable by such Borrower  hereunder
and under the Notes  shall  automatically  become  immediately  due and  payable
without  presentment  demand,  protest or other  formalities of any kind, all of
which are hereby expressly waived by such Borrower.

Notwithstanding any other provision herein to the contrary,  Defaults and Events
of Default shall have the following results:

                  (i)      a Default  or Event of  Default  with  respect to one
                           Borrower  shall not  constitute a Default or Event of
                           Default to any other Borrower;

                  (ii)     except as set forth in clause (iii) below,  a Default
                           or Event of Default  with respect to a Fund acting on
                           behalf of one or more  Borrowers  shall  constitute a
                           Default or Event of Default, as the case may be, only
                           to  the  Borrower  or  Borrowers  implicated  in,  or
                           affected by, the act or omission causing such Default
                           or Event of Default;

                  (iii)    a Fund  Default or Fund Event of Default with respect
                           to a Fund  acting on behalf of one or more  Borrowers
                           shall  constitute  a Default or Event of Default,  as
                           the case may be, to each Borrower issued by such Fund
                           for which such Fund  Default or Fund Event of Default
                           may   in   the    reasonable    discretion   of   the
                           Administrative  Agreement be  reasonably  expected to
                           have  a   Material   Adverse   Effect  on  each  such
                           Borrower's  ability to perform its obligations  under
                           this Agreement and the Notes; and

                  (iv)     an  Event  of  Default  of  the  type   described  in
                           paragraph  (n) of this Section 9 shall  constitute an
                           Event of Default to all Borrowers.

"Fund Event of Default"  shall mean an Event of Default  with  respect to a Fund
(A) of any of the types  described in  paragraphs  (b),  (f), (g), (h) or (k) of
this  Section 9, or (B)  arising  from such  Fund's  failure to comply  with the
covenants set forth in Sections 8.3, 8.4 and 8.5 hereof.  "Fund  Default"  shall
mean any of the covenants giving rise to Fund Events of Default,  whether or not
any  requirement  for the giving of notice,  the lapse of time,  or both, or any
other condition, has been satisfied.

Section 10.       The Administrative Agent

                  Section 10.1  Appointment,  Powers and  Immunities.  Each Bank
hereby  appoints and  authorizes  the  Administrative  Agent to act as its agent
hereunder with such powers as are specifically  delegated to the  Administrative
Agent by the terms of this  Agreement,  together  with such other  powers as are
reasonably  incidental thereto.  The Administrative Agent (which term as used in
this sentence and in Section 10.5 and the first  sentence of Section 10.6 hereof
shall  include  reference  to its  affiliates  and its  own and its  affiliates'
officers, directors, employees and agents):

                  (a)  shall  have no duties or  responsibilities  except  those
expressly set forth in this Agreement, and shall not by reason of this Agreement
be a trustee for any Bank;

                  (b) shall not be  responsible  to the Banks for any  recitals,
statements, representations or warranties contained in this Agreement, or in any
certificate or other document referred to or provided for in, or received by any
of them  under,  this  Agreement,  or for the  value,  validity,  effectiveness,
genuineness,  enforceability  or sufficiency of this Agreement,  any Note or any
other  document  referred  to or  provided  for  herein or for any  failure by a
Borrower or any other  Person to perform  any of its  obligations  hereunder  or
thereunder;

                  (c)  shall  not  be   required  to  initiate  or  conduct  any
litigation or collection proceedings hereunder; and

                  (d) shall not be  responsible  for any action taken or omitted
to be taken by it hereunder or under any other  document or instrument  referred
to or provided for herein or in  connection  herewith,  except for its own gross
negligence or willful misconduct.

The Administrative Agent may employ agents and  attorneys-in-fact  and shall not
be  responsible  for  the  negligence  or  misconduct  of  any  such  agents  or
attorneys-in-fact  selected by it in good faith.  The  Administrative  Agent may
deem and treat the payee of a Note as the holder thereof for all purposes hereof
unless and until a notice of the assignment or transfer  thereof shall have been
filed with the Administrative  Agent,  together with the consent of the Funds to
such assignment or transfer (to the extent required by Section 11.6(b) hereof),

                  Section   10.2   Reliance   by   Administrative   Agent.   The
Administrative Agent shall be entitled to rely upon any certification, notice or
other communication  (including,  without limitation,  any thereof by telephone,
telecopy, telegram or cable) reasonably believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or Persons,
and upon advice and statements of legal  counsel,  independent  accountants  and
other  experts  selected  by the  Administrative  Agent.  As to any  matters not
expressly provided for by this Agreement,  the Administrative Agent shall in all
cases be fully protected in acting,  or in refraining from acting,  hereunder in
accordance with instructions  given by the Majority Banks, and such instructions
of the Majority  Banks and any action  taken or failure to act pursuant  thereto
shall be binding on all of the Banks.

                  Section 10.3 Defaults.  The Administrative  Agent shall not be
deemed to have  knowledge or notice of the  occurrence  of a Default  unless the
Administrative  Agent has received  notice from a Bank or a Borrower  specifying
such Default and stating that such notice is a "Notice of Default". In the event
that the  Administrative  Agent  receives  such a notice of the  occurrence of a
Default, the Administrative Agent shall give prompt notice thereof to the Banks.
The Administrative Agent shall (subject to Section 10.7 hereof) take such action
with  respect  to such  Default  as shall be  directed  by the  Majority  Banks,
provided  that,  unless and until the  Administrative  Agent shall have received
such directions,  the  Administrative  Agent may (but shall not be obligated to)
take such  action,  or refrain  from taking such  action,  with  respect to such
Default as it shall deem  advisable in the best  interest of the Banks except to
the extent that this Agreement  expressly requires that such action be taken, or
not be taken,  only with the consent or upon the  authorization  of the Majority
Banks or all of the Banks.

                  Section 10.4 Rights as a Bank.  With respect to its Commitment
and the Loans made by it,  Chase  (and any  successor  acting as  Administrative
Agent) in its capacity as a Bank hereunder shall have the same rights and powers
hereunder  as any  other  Bank and may  exercise  the same as though it were not
acting as the Administrative Agent, and the term "Bank" or "Banks" shall, unless
the  context  otherwise  indicates,  include  the  Administrative  Agent  in its
individual  capacity.  Chase (and any successor acting as Administrative  Agent)
and its affiliates may (without  having to account  therefor to any Bank) accept
deposits from,  lend money to, make  investments in and generally  engage in any
kind of  banking,  trust or other  business  with  the  Funds  (and any of their
affiliates) as if it were not acting as the Administrative Agent, and Chase (and
any such  successor) and its affiliates may accept fees and other  consideration
from the Funds for  services in  connection  with this  Agreement  or  otherwise
without having to account for the same to the Banks.

                  Section 10.5 Indemnification. The Banks agree to indemnify the
Administrative  Agent (to the extent not  reimbursed  under Section 11.3 hereof,
but without  limiting  the  obligations  of the Funds under said  Section  11.3)
ratably in accordance with the aggregate  principal  amount of the Loans held by
the Banks (or, if no Loans are at the time  outstanding,  ratably in  accordance
with their respective  Commitments),  for any and all liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind and nature whatsoever that may be imposed on, incurred
by or asserted against the  Administrative  Agent arising out of or by reason of
any  investigation in or in any way relating to or arising out of this Agreement
or any other documents contemplated by or referred to herein or the transactions
contemplated hereby or the enforcement of any of the terms hereof or of any such
other documents,  provided that no Bank shall be liable for any of the foregoing
to the extent they arise from the gross negligence or willful  misconduct of the
party to be indemnified.

                  Section 10.6 Non-Reliance on  Administrative  Agents and Other
Banks.  Each Bank agrees that it has,  independently and without reliance on the
Administrative  Agent  or any  other  Bank,  and  based  on such  documents  and
information as it has deemed  appropriate,  made its own credit  analysis of the
Borrowers  and  decision  to  enter  into  this  Agreement  and  that  it  will,
independently  and without reliance upon the  Administrative  Agent or any other
Bank, and based on such documents and  information as it shall deem  appropriate
at the time,  continue to make its own analysis  and  decisions in taking or not
taking  action  under this  Agreement.  The  Administrative  Agent  shall not be
required to keep itself  informed as to the  performance  or  observance  by the
Borrowers of this  Agreement or any other  document  referred to or provided for
herein or to  inspect  the  Properties  or books of the  Borrowers.  Except  for
notices,  reports and other documents and information  expressly  required to be
furnished to the Banks by the Administrative Agent hereunder, the Administrative
Agent  shall not have any duty or  responsibility  to provide  any Bank with any
credit or other  information  concerning  the  affairs,  financial  condition or
business of the  Borrowers (or any of their  affiliates)  that may come into the
possession of the Administrative Agent or any of its affiliates.

                  Section  10.7  Failure to Act.  Except  for  action  expressly
required of the Administrative  Agent hereunder,  the Administrative Agent shall
in all cases be fully  justified in failing or refusing to act hereunder  unless
it shall receive further  assurances to its satisfaction from the Banks of their
indemnification  obligations  under  Section  10.5  hereof  against  any and all
liability  and  expense  that may be  incurred  by it by  reason  of  taking  or
continuing to take any such action.

                  Section 10.8 Resignation or Removal of  Administrative  Agent.
Subject to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving notice
thereof to the Banks and the Funds, and the Administrative  Agent may be removed
at any  time  with or  without  cause  by the  Majority  Banks.  Upon  any  such
resignation  or removal,  the  Majority  Banks shall have the right to appoint a
successor  Administrative  Agent with the  consent of the Funds,  which  consent
shall not be unreasonably  withheld or delayed.  If no successor  Administrative
Agent shall have been so appointed by the Majority Banks and shall have accepted
such appointment within 30 days after the retiring Administrative Agent's giving
of  notice  of  resignation  or the  Majority  Banks'  removal  of the  retiring
Administrative  Agent, then the retiring  Administrative Agent may, on behalf of
the  Banks  and with the  consent  of the  Funds,  which  consent  shall  not be
unreasonably withheld or delayed, appoint a successor Administrative Agent, that
shall be a bank that has an office in New York, New York with a combined capital
and surplus of at least $500,000,000.  Upon the acceptance of any appointment as
Administrative  Agent  hereunder  by  a  successor  Administrative  Agent,  such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights,  powers,  privileges  and duties of the retiring  Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative  Agent, the provisions of this Section 10
shall  continue  in effect for its  benefit in respect of any  actions  taken or
omitted to be taken by it while it was acting as the Administrative Agent.

Section 11.       Miscellaneous.

                  Section   11.1   Waiver.   No  failure  on  the  part  of  the
Administrative Agent or any Bank to exercise and no delay in exercising,  and no
course of dealing  with  respect to, any right,  power or  privilege  under this
Agreement or any Note shall operate as a waiver thereof, nor shall any single or
partial  exercise of any right,  power or privilege  under this Agreement or any
Note preclude any other or further exercise thereof or the exercise of any other
right,  power or privilege.  The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.

                  Section  11.2  Notices.   All  notices,   requests  and  other
communications   provided  for  herein  (including,   without  limitation,   any
modifications of, or waivers,  requests or consents under, this Agreement) shall
be  given  or made in  writing  (including,  without  limitation,  by  telecopy)
delivered to the intended recipient at the "Address for Notices" specified below
its name on the  signature  pages  hereof;  or, as to any  party,  at such other
address as shall be  designated  by such party in a notice to each other  party.
Except as otherwise provided in this Agreement,  all such communication shall be
deemed to have been duly given when  transmitted  by  telecopier  or  personally
delivered or, in the case of a mailed notice,  upon receipt,  in each case given
or addressed as aforesaid.

                  Section 11.3 Expenses, Etc.

                  (a) Each Borrower  agrees  severally  (pro rata based on their
respective Net Asset Values) (i) to reimburse the  Administrative  Agent for its
reasonable  out-of-pocket  costs and expenses  incurred in  connection  with the
development,  preparation  and  execution of, and any  amendment,  supplement or
modification  to, this Agreement and any Notes and any other documents  prepared
in connection herewith or therewith,  and the consummation and administration of
the transactions contemplated hereby and thereby, including, without limitation,
the reasonable fees and  disbursements of counsel to the  Administrative  Agent,
(ii) to reimburse each Bank and the  Administrative  Agent for all its costs and
expenses  incurred in connection  with the  enforcement or  preservation  of any
rights under this Agreement with respect to such  Borrower,  the Notes,  and any
such other documents,  including, without limitation, the fees and disbursements
of counsel to each Bank and of counsel  to the  Administrative  Agent,  (iii) to
indemnify and hold each Bank and the Administrative  Agent harmless from any and
all  recording and filing fees and any and all  liabilities  with respect to, or
resulting from any delay in paying, stamp, excise and other taxes, if any, which
may be payable or determined to be payable in connection  with the execution and
delivery  of,  or  consummation  or  administration  of any of the  transactions
contemplated by, or any amendment,  supplement or modification of, or any waiver
or consent under or in respect of, this Agreement, any Notes, and any such other
documents  with respect to such  Borrower,  and (iv) to indemnify  and hold each
Bank and the Administrative Agent (and their respective  affiliates,  directors,
officers,  agents and employees  (collectively with the Administrative Agent and
the Banks,  the  "Indemnified  Parties"))  harmless from and against any and all
other liabilities,  obligations, losses, damages, penalties, actions, judgments,
suits,  costs,  out-of-pocket  expenses or  disbursements  of any kind or nature
whatsoever  arising  from  or  in  connection  with  the  execution,   delivery,
enforcement,  performance and  administration of this Agreement,  any Notes, and
any such other  documents (all the foregoing in this clause (iv),  collectively,
the  "indemnified  liabilities"),  provided,  that each  Borrower  shall have no
obligation hereunder to the Administrative Agent or any Bank with respect to the
indemnified  liabilities  arising  from  (A) the  gross  negligence  or  willful
misconduct of the Administrative Agent or any such Bank, as the case may be, (B)
disputes  arising  solely  between or among the Banks or solely between any Bank
and the Administrative Agent, (C) the Administrative Agent or any Bank's failure
to comply with any requirement imposed by applicable law, unless such failure is
attributable  to a breach by a  Borrower  of any  representation,  warranty,  or
covenant under this  Agreement,  or (D) any such  indemnified  liabilities  that
relate to or arise from litigation  commenced by any Borrower  against the Banks
or the Administrative  Agent which seeks enforcement of any of the rights of any
Borrower hereunder or under any Note and is determined adversely to the Banks or
the Administrative Agent in a final, non-appealable judgment.

                  (b)  Notwithstanding  any other provision in this Agreement to
the  contrary,  to the extent any  obligation  to  reimburse  or  indemnify  any
Indemnified  Party  that  arises  pursuant  to  Section  11.3(a)  hereto  is not
attributable   to  any  particular   Borrower,   then  such   reimbursement   or
indemnification  shall  be  made by each  Borrower  (pro  rata  based  on  their
respective Net Asset Values).  To the extent any such obligation to reimburse or
indemnify any Indemnified  Party is attributable to one or more Borrowers,  then
such  reimbursement  or  indemnification  shall  be made  ratably  by each  such
Borrower.

                  Section 11.4  Amendments,  Etc. Except as otherwise  expressly
provided in this  Agreement,  any provision of this Agreement may be modified or
supplemented  only by an  instrument  in  writing  signed  by the  Funds and the
Majority  Banks,  or by the Funds and the  Administrative  Agent acting with the
consent of the Majority Banks, and any provision of this Agreement may be waived
by the Majority Banks or by the Administrative  Agent acting with the consent of
the Majority Banks;  provided,  that: (a) no modification,  supplement or waiver
shall,  unless  by  an  instrument  signed  by  all  of  the  Banks  or  by  the
Administrative  Agent acting with the consent of all of the Banks: (i) increase,
or  extend  the  term of the  Commitments,  or  extend  the  time or  waive  any
requirement for the reduction or termination of the Commitments, (ii) extend the

the rate at which interest is payable  thereon or any fee is payable  hereunder,
(v) alter the rights or  obligations  of a Borrower to prepay Loans,  (vi) alter
the manner in which  payments  or  prepayments  of  principal  interest or other

hereof,  or (x) modify the definition of the term "Majority  Banks" or modify in
any other  manner the number or  percentage  of the Banks  required  to make any
determinations  or waive any rights hereunder or to modify any provision hereof,
and (b) any  modification  or supplement of Section 10 hereof,  or of any of the
rights  or duties of the  Administrative  Agent  hereunder,  shall  require  the
consent of the Administrative Agent.

                  Section 11.5  Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

                  Section 11.6 Assignments and Participations.

                  (a)  The  Funds  may  not  assign  any  of  their   rights  or
obligations hereunder or under the Notes without the prior consent of all of the
Banks and the Administrative Agent.

                  (b) Each Bank may assign any of its Loans,  its Notes, and its
Commitment  (but only with the  consent of the  Administrative  Agent and, if no
Default exists and is  continuing,  the Funds) to an Eligible  Lender;  provided
that

                           (i)   no   such   consent   by  the   Funds   or  the
         Administrative Agent shall be required in the case of any assignment to
         another Bank;

                           (ii)   except  to  the   extent  the  Funds  and  the
         Administrative   Agent  shall  otherwise  consent,   any  such  partial
         assignment  (other than to another Bank) shall be in an amount at least
         equal to $2,000,000,

                           (iii)  each such  assignment  by a Bank of its Loans,
         Notes  or  Commitment  shall  be made in such  manner  so that the same
         portion  of  its  Loans,  Notes  and  Commitment  is  assigned  to  the
         respective assignee; and

                           (iv) each such assignment shall be effected  pursuant
         to an Assignment  and Acceptance in  substantially  the form of Exhibit
         11.6(b) hereto and the assignor and assignee shall deliver to the Funds
         and the Administrative Agent a fully executed copy thereof.

Upon  execution  and  delivery by the assignor and the assignee to the Funds and
the  Administrative  Agent of such Assignment and  Acceptance,  and upon consent
thereto by the Funds and the  Administrative  Agent to the extent required above
and acceptance thereof by the Administrative  Agent, the assignee shall have, to
the extent of such assignment  (unless  otherwise  consented to by the Funds and
the  Administrative  Agent),  the  obligations,  rights and  benefits  of a Bank
hereunder  holding the Commitment and Loans (or portions thereof) assigned to it
and specified in such  Assignment  and Acceptance (in addition to the Commitment
and Loans,  if any,  theretofore  held by such  assignee) and the assigning Bank
shall,  to the extent of such  assignment,  be released from the  Commitment (or
portion  thereof)  so  assigned.  Upon each such  assignment  the  assigning  or
assignee Bank shall pay the Administrative Agent an assignment fee of $3,000.

                  (c) A Bank  may  sell or  agree  to sell to one or more  other
Eligible  Lenders (each a  "Participant")  a participation in all or any part of
any Loans held by it, or in its Commitment, provided that such Participant shall
not have any  rights  or  obligations  under  this  Agreement  or any Note  (the
Participant's  rights against such Bank in respect of such  participation  to be
solely those set forth in the  agreements  executed by such Bank in favor of the
Participant).  All  amounts  payable  by the Funds to any Bank  under  Section 5
hereof in respect of Loans held by it, and its  Commitment,  shall be determined
as if such Bank had not sold or agreed to sell any  participations in such Loans
and  Commitment,  and as if  such  Bank  were  funding  each of  such  Loan  and
Commitment  in the same way that it is  funding  the  portion  of such  Loan and
Commitment in which no  participations  have been sold. In no event shall a Bank
that sells a  participation  agree with the  Participant to take or refrain from
taking any action hereunder except that such Bank may agree with the Participant
that it will not, without the consent of the Participant,  agree to (i) increase
or extend the term of such Bank's Commitment, (ii) extend the date fixed for the
payment of  principal of or interest on the related Loan or Loans or any portion
of any fee hereunder payable to the Participant,  (iii) reduce the amount of any
such  payment of  principal,  (iv) reduce the rate at which  interest is payable
thereon,  or any fee hereunder payable to the Participant,  to a level below the
rate at which the Participant is entitled to receive such interest or fee or (v)
consent to any modification,  supplement or waiver hereof to the extent that the
same, under Section 11.4 hereof, requires the consent of each Bank.

                  (d)  In  addition  to  the  assignments   and   participations
permitted  under the foregoing  provisions  of this Section  11.6,  any Bank may
(without  notice to the Funds,  the  Administrative  Agent or any other Bank and
without  payment of any fee) (i)  assign  and  pledge all or any  portion of its
Loans and its Note to any Federal Reserve Bank as collateral  security  pursuant
to Regulation A and any Operating  Circular  issued by such Federal Reserve Bank
and (ii) assign all or any portion of its rights  under this  Agreement  and its
Loans  and its  Note to an  affiliate.  No such  assignment  shall  release  the
assigning Bank from its obligations hereunder.

                  (e) A Bank may furnish any information concerning any Borrower
in the  possession of such Bank from time to time to assignees and  participants
(including  prospective  assignees and  participants),  subject however,  to the
provisions of Section 11.12(b) hereof.

                  Section  11.7  Survival.  The  obligations  of the Funds under
Section 11.3 hereof, and the obligations of the Banks under Section 10.5 hereof,
shall survive the repayment of the Loans and the  termination of the Commitments
(including, with respect to any Bank that does not agree to the extension of the
Commitment  Termination  Date  in  accordance  with  Section  2.10  hereof,  the
repayment of the Loans made by such Bank and the  termination  of the Commitment
of such Bank on the  Commitment  Termination  in effect  before giving effect to
such extension) and, in the case of any Bank that may assign any interest in its
Commitment  or Loans  hereunder,  shall  survive the making of such  assignment,
notwithstanding that such assigning Bank may cease to be a "Bank" hereunder.  In
addition,  each  representation  and  warranty  made,  or deemed to be made by a
notice of any Loan, herein or pursuant hereto,  shall survive the making of such
representation  and  warranty,  and no Bank shall be deemed to have  waived,  by
reason  of  making  any  Loan,  any  Default  that may  arise by  reason of such
representation   or  warranty   proving  to  have  been  false  or   misleading,
notwithstanding  that such Bank or the Administrative  Agent may have had notice
or knowledge or reason to believe that such representation or warranty was false
or misleading at the time such Loan was made.

                  Section 11.8  Caption.  The table of contents and captions and
section  headings  appearing  herein  are  included  solely for  convenience  of
reference and are not intended to affect the  interpretation of any provision of
this Agreement.

                  Section 11.9  Counterparts.  This Agreement may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same  instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart.

                  Section 11.10 Governing Law; Submission to Jurisdiction.  This
Agreement and the Notes shall be governed by, and construed in accordance  with,
the law of the State of New York.  Each Fund hereby submits to the  nonexclusive
jurisdiction  of the United States  District Court for the Southern  District of
New York and of the Supreme  Court of the State of New York  sitting in New York
County (including its Appellate  Division),  and of any other appellate court in
the State of New York, for the purposes of all legal proceedings  arising out of
or relating to this Agreement or the transactions contemplated hereby. Each Fund
hereby  irrevocably  waives,  to the fullest extent permitted by applicable law,
any  objection  that it may now or hereafter  have to the laying of the venue of
any  such  proceeding  brought  in such a court  and any  claim  that  any  such
proceeding brought in such a court has been brought in an inconvenient forum.

                  Section  11.11  Waiver of Jury Trial.  EACH OF THE FUNDS,  THE
ADMINISTRATIVE  AGENT AND THE BANKS HEREBY  IRREVOCABLY  WAIVES,  TO THE FULLEST
EXTENT  PERMITTED BY  APPLICABLE  LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT,  THE NOTES OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

                  Section 11.12    Treatment     of     Certain     Information;
Confidentiality.

                  (a) The Funds  acknowledge  that  from time to time  financial
advisory,  investment  banking and other  services may be offered or provided to
the Funds (in connection with this Agreement or otherwise) by any Bank or by one
or more  subsidiaries or affiliates of such Bank and the Funds hereby  authorize
such Bank to share any information  delivered to such Bank by the Funds pursuant
to this Agreement, or in connection with the decision of such Bank to enter into
this Agreement,  to any such subsidiary or affiliate,  it being  understood that
any such subsidiary or affiliate  receiving such  information  shall be bound by
the  provisions  of  paragraph  (b) below as if it were a Bank  hereunder.  Such
authorization  shall survive the repayment of the Loans and the  termination  of
the Commitments.

                  (b) Each Bank and the  Administrative  Agent agrees (on behalf
of itself and each of its affiliates,  directors,  officers,  members, employees
and  representatives)  to use  reasonable  precautions to keep  confidential  in
accordance with its customary procedures for handling  confidential  information
of the same nature and in accordance with safe and sound banking practices,  any
non-public  information  supplied to it by the Funds  pursuant to this Agreement
that is  identified by the Funds as being  confidential  at the time the same is
delivered  to the Banks and the  Administrative  Agent,  provided  that  nothing
herein  shall  limit  the  disclosure  of  any  such  information  (i)  if  such
information is when so supplied,  or thereafter shall have become, public (other
than through a violation of this Section 11.12,  (ii) to the extent  required by
statute,  rule, regulation or judicial process,  (iii) to counsel for any of the
Banks  or the  Administrative  Agent,  (iv) to  bank  examiners  (or  any  other
regulatory  authority having  jurisdiction  over any Bank or the  Administrative
Agent), or to auditors or accountants,  (v) to the  Administrative  Agent or any
other Bank (or to Chase Securities Inc.), (vi) in connection with any litigation
to which any one or more of the Banks or the Administrative Agent is a party, or
in connection with the enforcement of rights or remedies  hereunder,  (vii) to a
subsidiary  or  affiliate  of such Bank as  provided in  paragraph  (a) above or
(viii) to any assignee or participant (or  prospective  assignee or participant)
so long as such assignee or participant (or prospective assignee or participant)
first executes and delivers to the respective Bank a  Confidentiality  Agreement
substantially  in the form of Exhibit  11.12(b) hereto (or executes and delivers
to such Bank an  acknowledgment to the effect that it is bound by the provisions
of this Section 11.12(b),  which  acknowledgment  may be included as part of the
respective assignment or participation agreement pursuant to which such assignee
or participant  acquires an interest in the Loans hereunder);  provided further,
that (x) unless  specifically  prohibited by applicable law or court order, each
Bank and the Administrative Agent shall, prior to the disclosure thereof, notify
the Funds of any  request  for  disclosure  of any such  information  (A) by any
governmental  agency or  representative  thereof (other than any such request in
connection  with an examination of the financial  condition of such Bank by such
governmental  agency) or (B) pursuant to legal process and (y) in no event shall
any Bank or the  Administrative  Agent be  obligated  or  required to return any
materials  furnished  by the  Funds.  The  obligations  of each Bank  under this
Section 11.12 shall supersede and replace the obligations of such Bank under the
confidentiality letter in respect of this financing signed and delivered by such
Bank to the Funds prior to the date hereof; in addition,  the obligations of any
assignee  that has executed a  Confidentiality  Agreement in the form of Exhibit
11.12(b)  hereto shall be  superseded  by this Section  11.12 upon the date upon
which such assignee becomes a Bank hereunder pursuant to Section 11.6(b) hereof.

                  Section 11.13 Limited Recourse.  Anything in this Agreement to
the contrary notwithstanding, it is understood and agreed that the sole recourse
of the  Administrative  Agent or any Bank in respect of the  obligations  of any
Borrower with respect to (a) any Loan made to such Borrower (including,  without
limitation,  the  obligations of such Borrower to pay the principal of, interest
on and other  amounts  in  respect  of,  such  Loan) and (b) the  portion of the
commitment  fee and any amount  payable  pursuant  to Sections 7 and 11.3 hereof
allocated to such  Borrower  shall be limited to the assets of such Borrower and
that neither the Administrative  Agent nor any Bank shall have any right to look
to any  other  Borrower  or the  assets  thereof  for the  satisfaction  of such
obligations.






                  IN WITNESS  WHEREOF,  the  parties  hereto  have  caused  this
Agreement to be duly  executed and  delivered as of the day and year first above
written.

and in the  principal  amounts  provided  in the  Credit  Agreement,  and to pay
interest on the unpaid  principal  amount of each such Loan, at such office,  in
like money and funds,  for the period  commencing on the date of such Loan until
but  excluding  the date such Loan shall be paid in full, at the rates per annum
and on the dates provided in the Credit Agreement. The sole recourse of the Bank
in respect of the  obligations of the Fund on behalf of [Borrower]  evidenced by
this Note shall be limited to the assets held in such Fund and nothing contained
herein or in the Credit  Agreement shall create any right of the Bank to look to
the assets held in any other Fund for the satisfaction of such obligations.

                  The date,  amount,  and interest rate of each Loan made by the
Bank to the Fund for the benefit of [Borrower], and each payment made on account
of the principal thereof,  shall be recorded by the bank on its books and, prior
to any  transfer of this Note,  endorsed by the Bank on the  schedule  attached.
hereto or any  continuation  thereof,  provided  that the failure of the Bank to
make any such  recordation  (or any error in  making  any such  recordation)  or
endorsement  shall not affect the obligations of the Fund to make a payment when
due of any amount  owing under the Credit  Agreement  or hereunder in respect of
the Loans made by the Bank to the Fund for the benefit of [Borrower].

                  This Note is one of the  [Borrower]  Notes  referred to in the
Credit Agreement dated as of December 18, 1998 (as modified and supplemented and
in effect from time to time, the "Credit Agreement") between each Fund signatory
thereto,  the lenders party thereto (including the Bank) and The Chase Manhattan
Bank, as  Administrative  Agent, and evidences Loans made thereunder by the Bank
to the Fund for the  benefit of  [Borrower].  Terms used but not defined in this
Note have the respective meanings assigned to them in the Credit Agreement.

                  The Credit  Agreement  provides  for the  acceleration  of the
maturity of this Note upon the occurrence of certain events and for  prepayments
of Loans upon the terms and conditions specified therein.

                  Except as permitted  by Section 11.6 of the Credit  Agreement,
this Note may not be assigned by the Bank to any other Person.

                  This Note shall be governed by, and  construed  in  accordance
with, the law of the State of New York.

                            ASSIGNMENT AND ACCEPTANCE

                  Reference  is  made  to  the  Credit  Agreement,  dated  as of
December 18, 1998 (as modified and supplemented and in effect from time to time,
the "Credit  Agreement"),  between each Fund signatory thereto,  the Banks named
therein,  and The Chase Manhattan Bank, as administrative  agent for such Banks.
Terms defined in the Credit Agreement are used herein as defined therein.

                  _______________   (the  "Assignor")  and  _____________   (the
"Assignee") agree as follows:

                  1. The Assignor  hereby  irrevocably  sells and assigns to the
Assignee without recourse to the Assignor,  and the Assignee hereby  irrevocably
purchases and assumes from the Assignor without recourse to the Assignor,  as of
the Effective Date as set forth in Schedule I hereto (the "Effective  Date"), an
interest  (the  "Assigned  Interest")  in  and  to  the  Assignor's  rights  and
obligations  under the Credit  Agreement  with respect to the Commitment and the
Loans,  in a principal  amount and percentage for each Assigned  Interest as set
forth on Schedule 1.

                  2. The  Assignor (i) makes no  representation  or warranty and
assumes  no  responsibility  with  respect  to  any  statements,  warranties  or
representations  made in or in connection with the Credit Agreement or any other
instrument or document furnished pursuant thereto,  or the execution,  legality,

pursuant hereto or thereto;  and (iii) attaches the Note(s),  if any, held by it
evidencing  the Assigned  Interests and requests that the  Administrative  Agent

Notes  payable to the  Assignee  in the  respective  amounts  which  reflect the
assignment  being made hereby (and after giving effect to any other  assignments
which have become effective on the Effective Date).

                  3. The Assignee (i) represents and warrants that it is legally

agrees that it will,  independently and without reliance upon the Assignor,  the
Administrative  Agent  or any  other  Lender  and  based on such  documents  and
information as it shall deem  appropriate at the time,  continue to make its own
credit decisions in taking or not taking action under the Credit Agreement,  the
Notes or any other instrument or document  furnished pursuant hereto or thereto;
and (iv) appoints and authorizes the Administrative Agent to take such action as
administrative  agent on its behalf and to exercise  such powers and  discretion
under  the  Credit  Agreement,  the Notes or any other  instrument  or  document
furnished  pursuant  hereto or thereto as are  delegated  to the  Administrative
Agent by the terms thereof, together with such powers as are incidental thereto.

                  4. Following the execution of this  Assignment and Acceptance,
it  will  be  delivered  to  the  Administrative  Agent  for  acceptance  by the
Administrative Agent pursuant to Section 11.6 of the Credit Agreement, effective
as of the Effective Date (which date shall not,  unless  otherwise  agreed to by
the  Administrative  Agent, be earlier than five Business Days after the date of
such acceptance by the Administrative Agent).

                  5. Upon such  acceptance,  from and after the Effective  Date,
the  Administrative  Agent shall make all  payments  in respect of the  Assigned
Interest (including payments of principal,  interest, fees and other amounts) to
the Assignee which accrue subsequent to the Effective Date.

                  6. From and after the Effective  Date,  (i) the Assignee shall
be a  party  to the  Credit  Agreement  and,  to the  extent  provided  in  this
Assignment and Acceptance,  have the rights and obligations of a Bank thereunder
and under the Notes and shall be bound by the  provisions  thereof  and (ii) the
Assignor  shall,  to the extent  provided  in this  Assignment  and  Acceptance,

Agreement except as provided in Section 11.7 of the Credit Agreement.

construed in accordance with the law of the State of New York.

                  8. This  Assignment  and  Acceptance  may be  executed  in any
number of counterparts, all of which taken together shall constitute one and the
same  instrument and any of the parties  hereto may execute this  Assignment and

                  As provided in said Section 11.12, we are permitted to provide
you, as a prospective [holder of a participation in the Loans (as defined in the

to you a Confidentiality  Agreement substantially in the form hereof;  provided,
further,  that (x) unless  specifically  prohibited by  applicable  law or court
order, you agree, prior to the disclosure  thereof, to notify the Company of any

Ladies and Gentlemen:

         As counsel to American Century Government Income Trust (the "Trust"), I
am generally  familiar with its affairs.  Based upon this familiarity,  and upon
the  examination of such documents as I deemed  relevant,  it is my opinion that
the shares of the Trust  described in 1933 Act  Post-Effective  Amendment No. 37
and 1940 Act Amendment No. 38 to its Registration  Statement on Form N-1A, to be
filed with the Securities  and Exchange  Commission on May 7, 1999,  will,  when
issued, be validly issued, fully paid and nonassessable.

         For the  record,  it should be stated that I am an employee of American
Century  Services  Corporation,  an affiliated  corporation of American  Century
Government Income Trust, Inc., the investment advisor of the Trust.

         I  hereby  consent  to  the  use  of  this  opinion  as an  exhibit  to
Post-Effective Amendment No. 37 and Amendment No. 38, referenced above.

                                 Very truly yours,

                                 /s/Charles C.S. Park
                                 Charles C.S. Park

                                POWER OF ATTORNEY

         KNOW ALL MEN BY THESE PRESENTS, that the undersigned,  American Century
Government Income Trust,  hereinafter  called the "Trust",  and certain trustees
and officers of the Trust, do hereby constitute and appoint George A. Rio, David
C. Tucker,  Douglas A. Paul, Charles A. Etherington,  and Charles C.S. Park, and
each of them  individually,  their true and lawful  attorneys and agents to take
any and all action and execute any and all instruments  which said attorneys and
agents may deem  necessary  or  advisable to enable the Trust to comply with the
Securities  Act of 1933 and/or the  Investment  Company Act of 1940, as amended,
and any rules,  regulations,  orders, or other requirements of the United States
Securities  and  Exchange   Commission   thereunder,   in  connection  with  the
registration  under the Securities Act of 1933 and/or the Investment Company Act
of 1940,  as amended,  including  specifically,  but without  limitation  of the
foregoing,  power and  authority to sign the name of the Trust in its behalf and
to affix its seal,  and to sign the names of each of such  trustees and officers
in  their  capacities  as  indicated,  to any  amendment  or  supplement  to the
Registration  Statement filed with the Securities and Exchange  Commission under
