CENTENNIAL
AMERICA FUND, L.P.

Prospectus dated April 24, 1998

Centennial  America Fund,  L.P. is a no-load "money market" mutual fund with the
investment  objective  of  seeking  as  high a level  of  current  income  as is
consistent  with the  preservation  of capital and the maintenance of liquidity.
The Fund seeks to achieve  its  objective  through a  diversified  portfolio  of
short-term debt instruments  issued or guaranteed by the U.S.  Government or its
agencies or instrumentalities, maturing in, or having been called for redemption
in, 397 days or less.  The Fund seeks to generate  income that is not subject to
payment  or  withholding  of U.S.  Federal  income  tax for  qualifying  foreign
investors.

      An  investment in the Fund is neither  insured nor  guaranteed by the U.S.
Government.  While the Fund seeks to  maintain a stable net asset value of $1.00
per share, there can be no assurance that the Fund will be able to do so.

     Shares of the Fund may be purchased  only by foreign  investors who are not
treated as U.S.  citizens or  residents or as U.S.  corporations,  partnerships,
trusts or estates under the U.S. Internal Revenue Code of 1986, as amended.

      Shares of the Fund may be  purchased  directly  from  brokers  or  dealers
having  sales  agreements  with the Fund's  Distributor  and also are offered to
participants  in Automatic  Purchase and  Redemption  Programs (the  "Programs")
established by certain  brokerage  firms with which the Fund's  Distributor  has
entered  into  agreements  for that  purpose.  See "How to Buy  Shares"  in this
Prospectus. Program participants should also read the description of the Program
provided by their broker.

in the  Fund.  Please  read this  Prospectus  carefully  and keep it for  future

The  following  tables set forth the fees that an investor in the Fund might pay

Total Fund Operating Expenses                                 0.98%

      The purpose of these tables is to assist an investor in understanding  the
various  costs and  expenses  that an  investor  in the Fund will bear  directly
(shareholder   transaction   expenses)  or  indirectly  (annual  fund  operating
expenses).  "Other  Expenses"  includes  such expenses as custodial and transfer
agent fees, audit,  legal and other business  operating  expenses,  but excludes
extraordinary expenses. For further details, see the Fund's financial statements
included in the Statement of Additional Information.

      o EXAMPLE.  The following  example applies the above-stated  expenses to a
hypothetical $1,000 investment in shares of the Fund over the time periods shown
below,  assuming a 5% annual rate of return on the  investment and also assuming
that the shares are redeemed at the end of each stated period. The amounts shown
below are the cumulative costs of such  hypothetical  $1,000  investment for the
periods shown.

            1 YEAR         3 YEARS        5 YEARS        10 YEARS
            ------         -------        -------        --------
            $10            $31            $54            $120

      This  example  shows the effect of  expenses on an  investment  but is not
meant to state or predict actual or expected costs or investment  returns of the
Fund, all of which may be more or less than those shown.

INVESTMENT OBJECTIVE AND POLICIES

The Fund is a  no-load  "money  market"  fund.  It is an  open-end,  diversified
management  investment  company  organized as a Delaware limited  partnership on
March 5, 1987.  The Fund is  organized  as a limited  partnership  to permit the
income  earned  by the Fund on its  portfolio  to flow  through  to its  foreign
limited  partners  without being subject to U.S.  Federal income tax. The Fund's
partners,  including  its  limited  partners,  are also  referred  to  herein as
"shareholders"  or "investors".  The Fund's shares may be purchased at their net
asset  value,   which  will  remain  fixed  at  $1.00  per  share  except  under
extraordinary circumstances. (See "Purchase, Redemption and Pricing of Shares --
Determination  of Net Asset  Value Per  Share" in the  Statement  of  Additional
Information for further information). The value of Fund shares is not insured or
guaranteed by any government agency.  However, shares held in brokerage accounts
may be eligible for coverage by the Securities Investor  Protection  Corporation
for losses  arising from the insolvency of the brokerage  firm.  There can be no
assurance,  however,  that the Fund's net asset  value will not vary or that the
Fund will achieve its investment objective.  Prior to December 6, 1991, the Fund
was a longer-term  government  securities  fund that had a fluctuating net asset
value per share and an investment  objective of seeking high current  income and
safety of principal and had no restrictions on the maturity of the securities in
its   portfolio.   The  Fund's   investment   policies  and  practices  are  not
"fundamental"  policies  (as  defined  below)  unless  a  particular  policy  is
identified as fundamental.  See "Investment  Restrictions." The Managing General
Partners may change non- fundamental  investment  policies  without  shareholder
approval.

OBJECTIVE. The Fund's investment objective is to seek as high a level of current
income as is consistent with the  preservation of capital and the maintenance of
liquidity.  To produce  income  that is not subject to U.S.  Federal  income tax
withholding for its shareholders, the Fund invests in U.S. Government Securities
issued after July 18, 1984, in registered  form. In seeking its objective,  as a
matter of fundamental  policy, the Fund may invest only in obligations issued or
guaranteed by the U.S.  Government or its agencies or  instrumentalities  ("U.S.
Government  Securities"),  having a  maturity  of, or  having  been  called  for
redemption in, 397 days or less, or in repurchase  agreements  (described below)
under which such obligations are purchased.  The Fund intends to invest at least
75% of its total  assets  in U.S.  Government  Securities  under  normal  market
conditions.  The securities in which the Fund may invest may not yield as high a
level  of  current  income  as  longer-term  or  lower-rated  securities,  which
generally have less liquidity and experience greater price fluctuation.

ELIGIBLE INVESTORS.  The Fund is designed  exclusively for investors who are not
treated as U.S.  citizens or  residents or as U.S.  corporations,  partnerships,
trusts or estates  under the  Internal  Revenue  Code of 1986,  as amended  (the
"Internal  Revenue  Code").  Shares of the Fund are offered only to such foreign
investors, who must provide certification of their foreign status to the Fund on
Form W-8 on purchasing their shares. (See "How to Buy Shares").

INVESTMENT  RISKS. The Fund intends to exercise due care in the selection of its
portfolio securities.  However,  there is a risk that some of the issuers of the
Fund's  portfolio  securities  might  not be  able  to  meet  their  duties  and
obligations  on  interest  or  principal  payments at the time called for by the
instrument.  There is also the risk  that  because  of a  redemption  demand  by
shareholders of the Fund greater than anticipated by OppenheimerFunds, Inc. (the
"Manager"),  some of the Fund's portfolio securities might have to be liquidated
prior to maturity at a loss. Any of these risks, if  encountered,  could cause a
reduction in the net asset value of the Fund's shares.

      The Fund does not  intend  to  purchase  or sell  securities  for  trading
purposes because that activity may cause the Fund to be deemed to be "engaged in
a trade or business" in the United States for U.S.  Federal income tax purposes,
which  would  affect  the  withholding  status of its  distributions  to foreign
investors.  (See  "Distributions  and Taxes," below). It is the intention of the
Fund to purchase  securities and hold them until maturity to generate  portfolio
interest  income,  not capital  gains,  and therefore the Fund normally does not
intend to sell securities prior to their scheduled maturities. However, the Fund
may sell securities prior to maturity for unanticipated liquidity purposes.

      o YEAR 2000 RISKS.  Because many  computer  software  systems in use today
cannot  distinguish the year 2000 from the year 1900, the markets for securities
in which the Fund invests could be detrimentally  affected by computer  failures
beginning  January 1, 2000.  Failures of computer  systems  used for  securities
trading could result in settlement and liquidity problems for the fund and other
investors.  Data  processing  errors by  corporate  and  government  issuers  of
securities could result in production problems and economic  uncertainties,  and
those issuers may entail  substantial costs in attempting to prevent or fix such
errors,  all of which could have a negative effect on the Fund's investments and
returns.

INVESTMENT POLICIES. In seeking its objective,  the Fund may invest in the types
of securities listed below.

      O U.S. GOVERNMENT SECURITIES.  Securities issued or guaranteed by the U.S.
Government  include a variety of U.S.  Treasury  securities  that differ only in
their  interest  rates,  maturities  and dates of issuance.  Treasury bills have
maturities of one year or less,  Treasury notes have  maturities from one to ten
years, and Treasury bonds generally have maturities of greater than ten years at
the date of issuance.  U.S. Government agencies or instrumentalities which issue
or  guarantee  securities,  also  include,  but are not  limited to, the Federal
Housing Administration,  Farmers Home Administration,  Export-Import Bank of the
United  States,  Small Business  Administration,  Government  National  Mortgage
Association,  General Services  Administration,  Central Bank for  Cooperatives,
Federal  Home  Loan  Bank,  Federal  Home  Loan  Mortgage  Corporation,  Federal
Intermediate Credit Bank, Federal Land Bank, Maritime Administration,  Tennessee
Valley Authority,  District of Columbia Armory Board,  Federal National Mortgage
Association and the Student Loan Marketing Association. The Fund will not invest
in securities issued by the Inter-American  Development Bank, the Asian-American
Development Bank and the International  Bank for  Reconstruction and Development
or in pooled mortgages offered by the Federal Housing Administration or Veterans
Administration.

      Obligations of some U.S. Government agencies and instrumentalities may not
be supported by the full faith and credit of the United States.  Some are backed
by the right of the issuer to borrow from the U.S. Treasury; others, such as the
Federal National Mortgage  Association,  by the  discretionary  authority of the
U.S. Government to purchase the agencies' obligations;  while still others, such
as the Student Loan Marketing  Association,  are supported only by the credit of
the instrumentality.  In the case of securities not backed by the full faith and
credit  of the  United  States,  the Fund must look  principally  to the  agency
issuing or guaranteeing  the obligation for ultimate  repayment,  and may not be
able to assert a claim  against the United States itself in the event the agency
or instrumentality does not meet its commitments.

      O WHEN-ISSUED  AND DELAYED  DELIVERY  TRANSACTIONS.  The Fund may purchase
securities  on a  when-issued  basis and may  purchase or sell  securities  on a
delayed  delivery basis.  These terms refer to securities that have been created
and for  which a market  exists,  but  which  are not  available  for  immediate
delivery.  The Fund  does  not  intend  to  enter  into  such  transactions  for
speculative purposes.  During the period between the purchase and settlement, no
payment is made for the security  and no interest  accrues to the buyer from the
investment. There may be a risk of loss to the Fund if the value of the security
declines prior to the settlement date.

     O REPURCHASE AGREEMENTS. Pending the investment of the proceeds of sales of
its shares or portfolio securities, or pending distributions to shareholders, or
for liquidity  purposes based on reasonably  anticipated  liquidity needs of the
Fund, or in times of extraordinary  market uncertainty for defensive purposes to
preserve capital,  the Fund may acquire U.S.  Government  Securities  subject to
repurchase  agreements.  The  repurchase  agreement  is  collateralized  by  the
underlying  security.  The Fund's  repurchase  agreements  must  comply with the
collateral  requirements of Rule 2a-7 of the Investment  Company Act of 1940, as
amended (the  "Investment  Company Act").  If the vendor fails to pay the agreed
upon  repurchase  price on the delivery  date,  the Fund's risks may include any
costs of disposing of such collateral,  and any loss resulting from any delay in
foreclosing  on  the  collateral.  The  Fund  will  not  enter  into  repurchase
transactions  that will  cause more than 25% of the  Fund's  total  assets to be
subject to  repurchase  agreements.  The Fund will not enter  into a  repurchase
agreement  which will  cause  more than 5% of its total  assets to be subject to
repurchase  agreements  having a maturity  beyond  seven days.  See  "Repurchase
Agreements" in the Statement of Additional Information for further details.

RATINGS OF SECURITIES.  Under Rule 2a-7 of the Investment  Company Act, the Fund
uses the amortized  cost method to value its  portfolio  securities to determine
the Fund's net asset value per share.  Rule 2a-7 places  restrictions on a money
market  fund's  investments.  Under Rule 2a-7,  the Fund may purchase  only U.S.
dollar denominated securities that the Manager, under procedures approved by the
Fund's  Managing  General  Partners has determined have minimal credit risks and
are "Eligible Securities," as defined below.

      With respect to ratings, an "Eligible Security" is (a) a security that has
received a rating in one of the two highest  short-term rating categories by any
two "nationally  recognized statistical rating organizations" as defined in Rule
2a-7 ("Rating  Organizations"),  or, if only one Rating  Organization  has rated
that security,  by that Rating Organization (the "Rating  Requirements"),  (b) a
security that is  guaranteed,  and either the  guarantee or the party  providing
that guarantee meets the Rating  Requirements or (c) an unrated security that is
either  issued  by an issuer  having  another  security  that  meets the  Rating
Requirements  or is  judged  by  the  Manager  to be of  comparable  quality  to
investments that meet the Rating Requirements.

     Rule 2a-7 permits the Fund to purchase "First Tier  Securities,"  which are
Eligible  Securities  rated in the highest rating  category for short-term  debt
obligations  by at least  two  Rating  Organizations,  or,  if only  one  Rating
Organization has rated a particular security,  by that Rating  Organization,  or
comparable unrated  securities.  Under Rule 2a-7, the Fund may invest only up to
5% of its assets in "Second Tier Securities," which are Eligible Securities that
are not "First Tier  Securities."  In addition to the overall 5% limit on Second
Tier Securities, the Fund may not invest more than (i) 5% of its total assets in
the securities of any one issuer (other than the U.S.  Government,  its agencies
or  instrumentalities),  or (ii) 1% of its total assets or $1 million (whichever
is greater) in Second Tier  Securities  of any one issuer.  Additionally,  under
Rule 2a-7, the Fund must maintain a dollar-weighted  average portfolio  maturity
of no more than 90 days,  and the  remaining  maturity  of any single  portfolio
investment at the time of purchase may not exceed 397 days. The Fund's  Managing
General Partners have adopted  procedures under Rule 2a-7 pursuant to which they
have  delegated to the Manager their  responsibility  of  conforming  the Fund's
investments with the requirements of Rule 2a- 7 and those procedures.

      The Statement of Additional Information contains additional information on
the rating categories of Rating  Organizations.  Ratings at the time of purchase
will determine whether securities may be acquired under the above  restrictions.
Subsequent  downgrades in ratings may require  reassessments  of the credit risk
presented  by a  security  and may  require  sale of that  security.  The rating
restrictions  described  in this  Prospectus  do not apply to banks in which the
Fund's cash is kept. See "Ratings of  Securities"  in "Investment  Objective and
Policies" in the Statement of Additional Information for further details.

INVESTMENT RESTRICTIONS

The Fund has certain investment restrictions which, together with its investment
objective,  are fundamental policies changeable only by the vote of a "majority"
(as defined in the  Investment  Company  Act) of the Fund's  outstanding  voting
securities. Under some of those restrictions, the Fund cannot:

      o  invest  in  any  security  other  than  U.S.   Government   Securities,
mortgage-backed securities, and securities issued by private entities unless the
mortgage  collateral  underlying  such  securities  is insured,  guaranteed,  or
otherwise  backed  by the  U.S.  Government  or one or more of its  agencies  or
instrumentalities;

      o borrow money,  except from banks for temporary or emergency  purposes in
amounts not in excess of 5% of the value of the Fund's total  assets;  no assets
of the Fund may be pledged,  mortgaged  or  hypothecated  other than to secure a
borrowing,  and then in amounts not  exceeding  7.5% of the Fund's total assets;
borrowings  may not be made for  investment  leverage,  but  only for  liquidity
purposes to satisfy redemption requests when liquidation of portfolio securities
is considered inconvenient or disadvantageous;  however, the Fund may enter into
when-issued and delayed delivery transactions;

      o enter into a repurchase transaction that will cause more than 25% of the
Fund's total assets to be subject to such agreements;

      o make loans,  except that the Fund may purchase or hold debt  obligations
permitted  by its  other  fundamental  policies  and may enter  into  repurchase
transactions collateralized by cash or U.S. Government Securities having a value
equal at all  times  to at least  100% of the  value of the  securities  loaned,
including accrued interest;

      o  purchase  restricted  or  illiquid  securities   (including  repurchase
agreements of more than seven days' duration and other  securities  that are not
readily marketable) if more than 5% of the Fund's total assets would be invested
in such securities; or

      o purchase any securities  (other than U.S.  Government  Securities)  that
would cause more than 5% of the Fund's total assets to be invested in securities
of a  single  issuer,  or  purchase  more  than  10% of the  outstanding  voting
securities of an issuer.

Unless the Prospectus states that a percentage restriction applies on an ongoing
basis,  it applies only at the time the Fund makes an  investment,  and the Fund
need not sell  securities  to meet the  percentage  limits  if the  value of the
investment  increases  in  proportion  to  the  size  of  the  Fund.  Additional
investment  restrictions  are listed in "Other  Investment  Restrictions" in the
Statement of Additional Information.

HOW THE FUND IS MANAGED

ORGANIZATION  AND HISTORY.  The Fund's  Managing  General  Partners have overall
responsibility  for the  management of the Fund in  accordance  with the laws of
Delaware  governing  the   responsibilities   of  general  partners  of  limited
partnerships.  The Managing General Partners function like a board of directors.
They  establish the Fund's  policies and review its  management  and  operations
pursuant to an Agreement of Limited  Partnership  summarized below and reprinted
in the  Statement of  Additional  Information.  The Fund's  investment  adviser,
OppenheimerFunds,  Inc.,  is  responsible  for the  day-to-day  operation of the
Fund's business. The Fund also has a corporate Non-Managing General Partner that
does not  participate  in the  management  of the Fund,  but which is  obligated
(together with the Managing  General  Partners) to maintain an investment in the
Fund equal to 1% of its assets.  Oppenheimer  Partnership  Holdings,  Inc.,  the
Non-Managing  General Partner,  is a wholly owned  subsidiary of the Manager.  A
list of the Fund's Managing General Partners and officers and information  about
them are included in "Managing  General  Partners and Officers" in the Statement
of Additional Information.

SUMMARY OF THE PARTNERSHIP  AGREEMENT.  The Fund is a limited  partnership  that
issues  shares of limited  partnership  interests  that are of one  class.  As a
limited  partnership,  the Fund is not required to hold annual meetings and does
not intend to do so. The Fund will, however,  hold meetings of the partners from
time to time for  purposes  such as changing  fundamental  investment  policies,
approving an investment  advisory  agreement or a distribution  plan and, at the
request of investors owning 10% or more of the shares of the Fund, replacing its
general  partners.  All shares of the Fund are of one class,  have one vote and,
when issued,  are fully paid,  nonassessable  and redeemable.  See "Liability of
Limited Partners" below. All shares of the Fund have equal voting,  dividend and
liquidation  rights but have no subscription,  preemptive or conversion  rights.
There is no cumulative voting. The full text of the Partnership Agreement of the
Fund is set forth in the  Statement of  Additional  Information.  The  following
statements summarize and explain certain provisions of the Partnership Agreement
and are qualified in their entirety by the terms of the Partnership Agreement.

     o VOTING RIGHTS OF PARTNERS.  The Fund's limited  partners have the voting,
approval,  consent or similar rights  required under the Investment  Company Act
for voting  security  holders.  Limited  partners of the Fund have the exclusive
right to vote on  matters  affecting  the Fund as set  forth in the  Partnership
Agreement.  A meeting  of the  limited  partners  may be called by the  Managing
General  Partners or by limited  partners holding 10% or more of the outstanding
shares.  Limited  partners on the record  date of a meeting  will be entitled to
vote at that  meeting  if they are  admitted  as limited  partners  prior to the
meeting date. Under the Partnership Agreement,  any Managing General Partner may
be removed by the vote of two-thirds of the outstanding shares of the Fund.

      o GENERAL  PARTNERS.  The general partners of the Fund consist of a number
of  individuals,  referred to as Managing  General  Partners,  and one corporate
general partner,  referred to as the Non-Managing General Partner (together, the
"General  Partners").  The Managing General Partners have complete and exclusive
control over the management,  conduct and operation of the Fund's business.  The
General Partners are elected for an indefinite term by shareholders of the Fund.

     The  Partnership  Agreement  provides  that the  General  Partners  are not
personally  liable to any investor in the Fund for the  repayment of any amounts
standing  in the  account of such  investor,  except by reason of their  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of their office. The Partnership Agreement also provides
that the General  Partners  will not be liable to any  investor by reason of any
failure to withhold  income tax with respect to  distributions  of income or any
change in any Federal or state tax laws or in the interpretation of such laws as
they apply to the Fund or its  investors  so long as the General  Partners  have
acted  in good  faith  and in a  manner  reasonably  believed  to be in the best
interests  of the  investors.  The General  Partners  generally  are entitled to
indemnification from the Fund against liabilities and expenses to which they may
become subject in their capacity as General Partners of the Fund,  provided they
have acted in good faith and for a purpose which they reasonably  believed to be
in the best interests of the Fund or its investors.  Such indemnification by the
Fund is limited to the assets of the Fund.

     o  LIABILITY  OF LIMITED  PARTNERS.  Generally,  limited  partners  are not
personally  liable for obligations of a partnership  unless they  participate in
the control of the  partnership's  business.  Under the terms of the Partnership
Agreement,  the Fund's limited  partners do not have the right to participate in
the control of the Fund's  business,  but they may exercise the right to vote on
matters  affecting the basic structure of the Fund,  including matters requiring
investor approval under the Investment Company Act.

      Under  Delaware law, the liability of each limited  partner (in his or her
capacity as a limited  partner) for the losses,  debts and obligations of a Fund
is generally limited to that partner's capital  contribution (which is the price
of shares  purchased  by that  partner net of all sales  charges) and his or her
share of any undistributed  income or assets of the Fund.  Limited partners may,
however, under certain  circumstances,  be required to return amounts previously
distributed to them for the benefit of the Fund's creditors. The Fund intends to
include in its  contracts a provision  limiting  the claims of  creditors to the
Fund's  assets and may carry  insurance in such amounts as the Managing  General
Partners, in their judgment,  consider reasonable to cover potential liabilities
of the Fund. In addition,  the  Partnership  Agreement for the Fund provides for
indemnification  out of the Fund's property for any shareholder  held personally
liable for any obligation of the Fund. The  Partnership  Agreement also provides
that the Fund shall, upon request,  assume the defense of any claim made against
any  shareholder  for any act or obligation of the Fund and satisfy any judgment
thereon.  Thus, the risk of a shareholder incurring financial loss on account of
his or her liability as a limited partner is limited to  circumstances  in which
the Fund itself would be unable to meet its  obligations.  The Manager  believes
that, in view of the above and in view of the character of the operations of the
Fund as an investment company, the risk of personal liability to shareholders is
extremely remote. The foregoing  provisions do not apply to any liability of the
Fund arising out of any liability of a limited  partner for  withholding  tax on
his or her  shares,  whether  due to  improper  certification  of tax  status or
otherwise.

   
      o  ADMISSION  OF LIMITED  PARTNERS.  In order to be  admitted as a limited
partner,   a  purchaser  of  shares  is  required  to  complete  a   partnership
subscription  agreement.  Admission  of a purchaser  as a limited  partner  also
requires  the consent of the Managing  General  Partners.  The Managing  General
Partners  of the Fund,  while  recognizing  that they have the right to withhold
their consent,  have stated that they intend to give such consent as a matter of
course to eligible investors.
    

      o PROHIBITION OF ASSIGNMENT OR TRANSFER OF SHARES. Limited partners of the
Fund do not have the right to voluntarily transfer or assign their shares to any
other  person  other  than to secure a loan.  In the event  that a person who is
holding shares as collateral  forecloses on such  collateral,  such person shall
not have the right to be  substituted  as a limited  partner  but shall have the
right  (upon  presentation  of  satisfactory  evidence to the  Managing  General
Partners of the right to succeed to the interests of the limited  partner):  (1)
to redeem  the  shares and (2) to  receive  distributions  with  respect to such
shares.  Under  limited  circumstances,  a  successor  in  interest of a limited
partner shall have the right to be substituted as a limited partner.

      o TERM OF EXISTENCE -  DISSOLUTION.  The Fund will continue until December
31,  2037,  but  shall  be  dissolved  before  that  date if and  when:  (1) the
shareholders of the Fund approve the prior dissolution of the Fund; (2) the Fund
disposes  of all of its  assets;  or (3) a  General  Partner  withdraws  and the
remaining  General  Partners  do not elect to  continue  the  operations  of the
Partnership;  or (4)  there  are  no  remaining  General  Partners  (unless  the
shareholders agree by unanimous vote to continue the Fund in circumstances where
the last  remaining  General  Partner was not  removed by them,  and new General
Partners are promptly elected by the shareholders).

      Except by  requiring  the Fund to redeem  outstanding  shares as described
under "How to Sell Shares,"  limited partners have no right to the return of any
part  of  their  contributions  to the  Fund  until  dissolution  of  the  Fund.
Distributions by the Fund,  whether upon  redemption,  dissolution or otherwise,
will be in proportion to the number of outstanding shares held without regard to
the dollar  amount  contributed  to the Fund or the amount of any profits of the
Fund received.

      o OTHER  PROVISIONS.  The  Partnership  Agreement  also  provides  for the
pricing,  purchase  and  redemption  of shares of the Fund as  described in this
Prospectus, as well as procedures relating to the giving of notices, the calling
of  meetings  and  solicitation  of  shareholder  consents.  In  addition,   the
Partnership  Agreement contains  provisions relating to the maintenance of books
and records by the Fund, the  accounting  procedures to be followed by the Fund,
the  allocation for U.S.  Federal income tax purposes of items of income,  gain,
loss,  deduction  and credit,  and the  procedures  by which  amendments  to the
Partnership Agreement may be effected. Limited partners have the right to obtain
current  copies of the  Partnership  Agreement  and certain other records of the
Fund.  The records of the Fund,  although  available  to limited  partners  upon
request and to certain other persons in connection  with Fund business,  are not
matters of public record.

THE  MANAGER AND ITS  AFFILIATES.  The  Manager  has  operated as an  investment
adviser  since 1959.  The Manager  (including  subsidiaries)  currently  manages
investment  companies,  including other  Oppenheimer  funds, with assets of more
than $85 billion as of March 31, 1998, and with more than 4 million  shareholder
accounts.  The  Manager is owned by  Oppenheimer  Acquisition  Corp.,  a holding
company  owned  in part by  senior  management  of the  Manager  and  ultimately
controlled  by  Massachusetts  Mutual  Life  Insurance  Company,  a mutual  life
insurance company which also advises pension plans and investment companies.

      The management services provided to the Fund by the Manager,  and services
provided by the  Distributor and the Transfer Agent to  shareholders,  depend on
the smooth functioning of their computer systems. Many computer software systems
in use today cannot  distinguish the year 2000 from the year 1900 because of the
way dates are encoded and calculated.  That failure could have a negative impact
on handling securities trades, pricing and accounting services. The Manager, the
Distributor and Transfer Agent have been actively  working on necessary  changes
to their  computer  systems  to deal with the year 2000 and  expect  that  their
systems  will be  adapted  in time  for the  event,  although  there  cannot  be
assurance of success. Additionally,  because the services they provide depend on
the interaction of their computer  systems with the computer systems of brokers,
information  services and other parties, any failure on the part of the computer
systems  of those  third  parties  to deal  with the year  2000 may also  have a
negative effect on the services provided to the Fund.

      o FEES AND  EXPENSES.  Subject to the  authority of the  Managing  General
Partners,  the Manager supervises the investment  operations of the Fund and the
composition  of its  portfolio  and furnishes  advice and  recommendations  with
respect  to  investments,  investment  policies  and the  purchase  and  sale of
securities,  pursuant to an Investment  Advisory  Agreement with the Fund. Under
the Investment Advisory  Agreement,  the Fund pays the Manager a fee computed on
the  aggregate  net assets of the Fund as of the close of business  each day and
payable monthly at the following  annual rates:  0.45% of the first $500 million
of net assets and 0.40% of net assets over $500  million.  See "The  Manager and
Its  Affiliates"  in the Statement of Additional  Information  for more complete
information about the Investment Advisory Agreement,  including a description of
exculpation provisions, portfolio transactions, and Fund expenses.

     O THE CUSTODIAN.  The Custodian of the assets of the Fund is Citibank, N.A.
The Manager and its  affiliates  presently have banking  relationships  with the
Custodian.

     o THE TRANSFER  AGENT.  Shareholder  Services,  Inc.,  a subsidiary  of the
Manager,  acts as transfer agent and  shareholder  servicing agent on an at cost
basis  for the Fund and  other  mutual  funds  advised  by a  subsidiary  of the
Manager,  and as  transfer  agent for  certain  other  funds  managed by persons
unaffiliated with the Manager.  Direct shareholders should forward any inquiries
regarding  the Fund to the Transfer  Agent at the address or either of the phone
numbers shown on the back cover of this Prospectus.  Program participants should
direct any inquiries regarding the Fund to their brokers or dealers.

PERFORMANCE OF THE FUND

EXPLANATION  OF  PERFORMANCE  TERMINOLOGY.  The Fund uses the terms  "yield" and
"compounded  effective  yield" to illustrate its  performance.  This performance
information  may be useful to help you see how well your investment has done and
to compare it to other money market funds.

      It is  important  to  understand  that the Fund's  yields  represent  past
performance   and  should  not  be  considered  to  be   predictions  of  future
performance. The Fund's investment performance will vary over time, depending on
market conditions, the composition of the portfolio, and expenses. More detailed
information  about how yields are  calculated  is contained in the  Statement of
Additional  Information,  which also  contains  information  about other ways to
measure and compare the Fund's performance.

      o YIELD. Different types of yields may be quoted to show performance.  The
"yield" of the Fund is the income  generated by an investment in the Fund over a
seven-day  period,  which is then  "annualized."  In annualizing,  the amount of
income  generated  by the  investment  during  that  seven days is assumed to be
generated each week over a 52-week  period,  and is shown as a percentage of the
investment.

      o  COMPOUNDED  EFFECTIVE  YIELD.  The  "compounded   effective  yield"  is
calculated  similarly,  but the annualized income earned by an investment in the
Fund is assumed to be reinvested in additional shares. The "compounded effective
yield"  will be  slightly  higher  than the yield  because  of the effect of the
assumed reinvestment.

ABOUT YOUR ACCOUNT

HOW TO BUY SHARES

As stated above, the Fund's shares are offered only to foreign investors who are
not treated as U.S. citizens or residents or as U.S. corporations, partnerships,
trusts  or  estates  under  the  Internal   Revenue  Code   ("eligible   foreign
investors").  All purchasers of the Fund's shares are required to become limited
partners of the Fund. (See "Admission of Limited Partners," above.)

      Shares of the Fund may be purchased at their offering price,  which is net
asset value per share,  without  sales  charge.  The net asset value will remain
fixed  at  $1.00  per  share,  except  under  extraordinary  circumstances  (see
"Determination  of Net Asset  Value Per Share" in the  Statement  of  Additional
Information for further  details),  but there is no guarantee that the Fund will
maintain a stable net asset  value of $1.00 per share.  Shares may be  purchased
through  "Automatic  Purchase and  Redemption  Programs" or "Direct  Purchases,"
described below. The Fund's shares may be purchased through any dealer or broker
which  has a sales  agreement  with the  Fund's  distributor,  Centennial  Asset
Management  Corporation (the  "Distributor"),  a wholly-owned  subsidiary of the
Manager,  or  with  OppenheimerFunds  Distributor,  Inc.,  also  a  wholly-owned
subsidiary  of the  Manager,  which  acts as the  Sub-Distributor  of the Fund's
shares  pursuant  to an  agreement  with the  Distributor.  Dealers  and brokers
purchasing  shares by phone should call the Distributor at  1-800-525-7041.  The
Distributor may, in its sole discretion,  accept or reject any order to purchase
the Fund's shares.

      All checks for the payment of  purchases  of Fund  shares  should be drawn
only on U.S.  banks  and  must  be  payable  in  U.S.  dollars.  Subject  to the
discretion  of the  Distributor,  checks  drawn on non- U.S.  banks  will not be
considered  payment and shares will not be purchased for the investor's  account
until U.S.  dollars are collected (in Federal Funds) from the check by the Fund.
If there are  collection  charges on such checks,  those charges may be deducted
from the purchase payment,  thereby reducing the number of shares purchased.  No
daily  distributions  will begin to accrue for investors  submitting such checks
until the regular  business day after shares are purchased with Federal Funds in
U.S. dollars collected on the purchase check. (See "Distributions" below).

     The minimum  initial  investment is $500 ($2,500 if by Federal Funds wire),
except as otherwise described in this Prospectus.  Subsequent  purchases must be
in amounts of $25 or more and may be made through  authorized dealers or brokers
or by forwarding payment to the Distributor at P.O. Box 5143, Denver,  Colorado,
80217 with the name(s) of all account owners, the account number and the name of
the Fund. The minimum initial and subsequent purchase requirements are waived on
purchases made by  reinvesting  distributions  from any of the "Eligible  Funds"
(see  "Exchange  Privilege"  below) or by  reinvesting  distributions  from unit
investment  trusts for which  reinvestment  arrangements have been made with the
Distributor.   Under  an  Automatic  Investment  Plan,  initial  and  subsequent
investments  must be at least  $25.  No share  certificates  will be issued  for
shares of the Fund unless  specifically  requested  in writing by an investor or
the dealer or broker.

     The Fund  intends to be as fully  invested as  practicable  to maximize its
yield. Therefore, daily distributions will accrue on newly-purchased shares only
after the  Distributor  accepts  the  purchase  order at its  address in Denver,
Colorado,  on a day the New York  Stock  Exchange  (the  "Exchange")  is open (a
"regular business day"), under one of the methods of purchasing shares described
below.  The purchase will be made at the net asset value next  determined  after
the Distributor accepts the purchase order.

      The  Fund's  offering  price  (and net  asset  value)  for its  shares  is
determined twice each regular business day at 12:00 Noon and at the close of the
Exchange, which is normally 4:00 P.M. (all references to time in this Prospectus
mean New York time),  but may be earlier on some days,  by dividing the value of
the Fund's net assets by the number of shares  outstanding.  The Fund's Managing
General Partners have established  procedures for valuing the Fund's securities,
using the "amortized cost method" of valuation,  as described in  "Determination
of Net Asset Value Per Share" in the Statement of Additional Information.

   
SPECIAL  TAX  CONSIDERATIONS.  Because  the  Fund  is  organized  as  a  limited
partnership  based in the United States and relies on certain  provisions of the
Internal  Revenue  Code in  operating  in a manner  designed to  eliminate  U.S.
Federal income tax and withholding on distributions of interest to shareholders,
certain tax factors about the Fund's operations, discussed more fully under "Tax
Considerations for Fund Investors,"  below,  should be considered by prospective
investors before investing. All prospective investors must furnish the Fund with
a Certificate of Foreign Status on Form W-8,  together with the Special Power of
Attorney  and  representations.  If the Fund does not receive a  Certificate  of
Foreign Status on Form W-8 for an investor,  the Fund must withhold U.S. Federal
income tax from any  distributions  to the  shareholder  to the extent that such
distributions  include income from U.S. sources.  By completing the Application,
each  prospective  investor  is signing  the Fund's  Partnership  Agreement  and
consenting to the disclosure of the information  contained in the Certificate of
Foreign Status  (including the investor's  name and address) to the Fund and, to
the extent required by the Internal  Revenue Code, to the U.S.  Internal Revenue
Service and to issuers of securities in which the Fund invests.
    

PURCHASES THROUGH AUTOMATIC PURCHASE AND REDEMPTION PROGRAMS. Shares of the Fund
are available under Automatic Purchase and Redemption  Programs  ("Programs") of
broker-dealers that have entered into an agreement with the Distributor for that
purpose.  Broker-dealers  whose clients participate in such Programs will invest
the "free cash balances" of such client's  Program account in shares of the Fund
if the Fund has been  selected as the primary fund by the client for the Program
account.  Such purchases will be made by the broker-dealer  under the procedures
described  in  "Guaranteed   Payment"  below.  Each  Program  may  have  minimum
investment  requirements  established by the  broker-dealer.  The description of
each Program provided by the broker-dealer  should be consulted for details, and
all questions  about  investing in,  exchanging or redeeming  shares of the Fund
through a Program should be directed to the broker-dealer.

   
DIRECT  PURCHASES.  An eligible  foreign  investor who does not participate in a
Program (a "direct shareholder") may directly purchase shares of the Fund or may
purchase shares through any  broker-dealer  which has a sales agreement with the
Distributor or the Sub-Distributor.  There are two ways to make a direct initial
investment,  either (1) complete a Centennial Funds New Account  Application and
mail it with payment to the Distributor at P.O. Box 5143, Denver, Colorado 80217
(if no dealer is named in the Application,  the Sub-Distributor  will act as the
dealer),  or (2) by Federal Funds wire, as described  below.  Purchases  made by
Application  should have a check enclosed,  or payment may be made by one of the
alternative means described below.
    

      o PAYMENT BY CHECK.  Orders for shares  purchased by check in U.S. dollars
drawn on a U.S.  bank will be effected on the regular  business day on which the
check  (and  the  Application,  if  the  account  is  new)  is  accepted  by the
Distributor.  Distributions will begin to accrue on such shares the next regular
business  day  after  the  purchase  order is  accepted  and  Federal  Funds are
available.  For checks not drawn on a U.S. bank in U.S. dollars, the shares will
not be purchased until the  Distributor is able to convert the purchase  payment
to Federal Funds, and  distributions  will begin to accrue on such shares on the
next regular business day. The minimum initial investment by check is $500.

     o PAYMENT BY FEDERAL  FUNDS WIRE.  Shares of the Fund may be  purchased  by
direct  shareholders  by Federal Funds wire.  The minimum  investment by wire is
$2,500.  The  investor  must FIRST call the  Distributor's  Wire  Department  at
1-800-852-8457 (from within the U.S.) or 303-768-3200 (from outside the U.S.) to
notify the  Distributor of the  transmittal  of the wire and to receive  further
instructions. The investor's bank must wire the Federal Funds to Citibank, N.A.,
ABA No.  0210-0008-9,  for credit to Concentration  Account No.  3737-5666,  for
further credit to Centennial America Fund, L.P. (Custodian Account No. 846080).

     The wire must state the investor's name. Distributions will begin to accrue
on  newly-purchased  shares on the purchase  date if the Federal Funds and order
for the purchase are  received  and accepted by 12:00 Noon.  Distributions  will
begin to  accrue  on the next  regular  business  day if the  Federal  Funds and
purchase order are received and accepted between 12:00 Noon and the close of the
Exchange,  which is  normally  4:00 P.M.,  but may be earlier on some days.  The
investor  must  also  send the  Distributor  a  completed  Application  when the
purchase  order  is  placed  to  establish  a new  account  and  the  investor's
Certificate of Foreign Status (Form W-8).

      O AUTOMATIC  INVESTMENT PLAN. Under an Automatic  Investment Plan,  direct
shareholders may make automatic monthly investments in the Fund (minimum $25) by
authorizing the Fund's Transfer  Agent, as agent for the  Distributor,  to debit
the investor's  account at a U.S. domestic bank, savings and loan association or
credit  union.  If a new account is being  established  under the Plan,  a check
(minimum $25) for the initial  investment  must accompany the  Application.  The
authorized  amount may be changed or participation in the Plan may be terminated
at any time by writing to Shareholder  Services,  Inc. ("the Transfer Agent"). A
reasonable  period  (approximately  15 days) is required  after  receipt of such
instructions to implement them. The Fund reserves the right to amend, suspend or
discontinue  offering  Automatic  Investment  Plans  at any time  without  prior
notice.

GUARANTEED  PAYMENT.  Broker-dealers  with sales agreements with the Distributor
(including   broker-dealers   who  have  made  special   arrangements  with  the
Distributor  for purchases for Program  accounts) may place purchase orders with
the  Distributor  for  purchases  of the Fund's  shares prior to 12:00 Noon on a
regular  business  day,  and the order will be  effected  at the net asset value
determined at 12:00 Noon that day if the  broker-dealer  guarantees that payment
for such shares in Federal Funds will be received by the Fund's  Custodian prior
to 2:00 P.M. on the same day.  Distributions on such shares will begin to accrue
on the purchase  date. If an order is received  between 12:00 Noon and the close
of the New York  Stock  Exchange  (which  is  normally  4:00  P.M.) on a regular
business day with the broker-dealer's  guarantee that payment for such shares in
Federal  Funds  will be  received  by the  Custodian  prior to the  close of the
Exchange the next regular  business day, the order will be effected at the close
of the  Exchange on the day the order is  received,  and  distributions  on such
shares  will begin to accrue on the next  regular  business  day if the  Federal
Funds are received by the required time. If the  broker-dealer  guarantees  that
the Federal Funds payment will be received by the Fund's  Custodian by 2:00 P.M.
on a regular  business  day on which an order is placed for shares  after  12:00
noon,  the order  will be  effected  at the close of the  Exchange  that day and
distributions will begin to accrue on such shares on the purchase date.

GENERAL.  Dealers and brokers who process orders for the Fund's shares on behalf
of their customers may charge a fee for this service. That fee can be avoided by
purchasing  shares  directly  from  the  Fund.  The  Distributor,  in  its  sole
discretion,  may accept or reject any order for  purchase of the Fund's  shares.
The sale of shares will be suspended during any period when the determination of
net asset value is  suspended,  and may be  suspended  by the  Managing  General
Partners whenever they judge it in the best interest of the Fund to do so.

SERVICE PLAN.  The Fund has adopted a Service Plan (the "Plan") under Rule 12b-1
of the  Investment  Company Act  pursuant to which the Fund will  reimburse  the
Distributor  for all or a portion of its costs  incurred in connection  with the
personal  service  and  maintenance  of  accounts  that  hold Fund  shares.  The
Distributor will use all the fees received from the Fund to compensate  dealers,
brokers, banks, or other institutions  ("Recipients") each quarter for providing
personal service and maintenance of accounts that hold Fund shares. The services
to be provided by Recipients  under the Plan  include,  but shall not be limited
to, the following:  answering routine  inquiries from the Recipient's  customers
concerning  the  Fund,  providing  such  customers  with  information  on  their
investment in Fund shares,  assisting in the  establishment  and  maintenance of
accounts or sub-accounts  in the Fund,  making the Fund's  investment  plans and
dividend  payment options  available,  and providing such other  information and
customer  liaison services and the maintenance of accounts as the Distributor or
the Fund may reasonably  request.  Plan payments by the Fund to the  Distributor
will be made quarterly in the amount of the lesser of (i) 0.05% (0.20% annually)
of the net asset value of the Fund,  computed  as of the close of each  business
day or (ii) the Distributor's  actual distribution  expenses for that quarter of
the type approved by the Managing General  Partners.  Any unreimbursed  expenses
incurred  for any  quarter  by the  Distributor  may not be  recovered  in later
periods. The Plan has the effect of increasing annual expenses of the Fund by up
to 0.20% of its average annual net assets from what its expenses would otherwise
be. In addition, the Manager may, under the Plan, from time to time from its own
resources  (which may include  the  profits  derived  from the  advisory  fee it
receives  from  the  Fund),   make  payments  to  Recipients  for  distribution,
administrative  and accounting  services  performed by  Recipients.  For further
details, see "Service Plan" in the Statement of Additional Information.

HOW TO SELL SHARES

PROGRAM PARTICIPANTS. Program participants may redeem shares held in the Program
by writing checks as described below, or by contacting their dealer or broker. A
Program  participant  may also arrange for "Expedited  Redemptions" as described
below, only through their dealer or broker.

SHARES  OF THE  FUND  OWNED  DIRECTLY.  Shares  of the  Fund  owned  by a direct
shareholder (not through a Program) may be redeemed in the following ways:

      o REGULAR REDEMPTION PROCEDURES. A direct shareholder who wishes to redeem
some or all shares in an account  (whether or not  represented by  certificates)
under the Fund's regular  redemption  procedures  must send the following to the
Fund's  transfer  agent,  Shareholder  Services,  Inc.,  P.O. Box 5143,  Denver,
Colorado  80217  [send  courier or express  mail  deliveries  to 10200 E. Girard
Avenue,  Building  D,  Denver,  Colorado  80231]:  (1)  a  written  request  for
redemption signed by all registered owners exactly as the shares are registered,
including  fiduciary  titles,  if any, and specifying the account number and the
dollar  amount  or  number of shares  to be  redeemed;  (2) a  guarantee  of the
signatures  of  all  registered  owners  on  the  redemption  request  or on the
endorsement on the share  certificate  or  accompanying  stock power,  by a U.S.
bank, trust company, credit union or savings association, or foreign bank having
a U.S.  correspondent bank or a U.S. registered dealer and broker in securities,
municipal securities or government securities,  or by a U.S. national securities
exchange,  registered  securities  association  or  clearing  agency;  (3) share
certificates,  if any, issued for any of the shares to be redeemed;  and (4) any
additional  documents which may be required by the Transfer Agent for redemption
by corporations, partnerships or other organizations, executors, administrators,
trustees,  custodians,  guardians,  or if the  redemption is requested by anyone
other than the  shareholder(s)  of record.  Transfers  of shares are  subject to
similar requirements.

      A signature  guarantee is not required for redemptions of $50,000 or less,
requested by and payable to all direct shareholders of record, to be sent to the
address  of  record  for that  account.  To avoid  delay in  redemption,  direct
shareholders  having  questions  about  these  requirements  should  contact the
Transfer Agent in writing or by calling 1-800-525-9310 (from within the U.S.) or
303-768-3200  (from outside the U.S.) before submitting a request.  From time to
time, the Transfer  Agent, in its sole  discretion,  may waive any or certain of
the foregoing requirements in particular cases.  Redemption or transfer requests
will not be honored until the Transfer Agent receives all required  documents in
proper form.

      o EXPEDITED  REDEMPTION  PROCEDURE.  In addition to the regular redemption
procedure set forth above,  direct shareholders whose shares are not represented
by certificates may arrange to have redemption  proceeds of $2,500 or more wired
in Federal Funds to a designated  commercial bank if the bank is a member of the
Federal Reserve wire system.  There is a $10 fee for each Federal Funds wire. To
place a wire redemption request, call the Transfer Agent at 1-800-852-8457.  The
account number of the designated  financial  institution and the bank ABA number
must be supplied to the Transfer Agent on the  Application or dealer  settlement
instructions  establishing  the account or may be added to existing  accounts or
changed only by signature guaranteed instructions to the Transfer Agent from all
shareholders of record. Such redemption requests may be made by telephone,  wire
or written  instructions  to the  Transfer  Agent.  The wire for the  redemption
proceeds of shares redeemed prior to 12:00 noon, New York time, normally will be
transmitted  by the Transfer  Agent to the  shareholder's  designated  U.S. bank
account  on the day the  shares  are  redeemed  (or,  if that  day is not a bank
business day, on the next bank business  day).  Shares  redeemed  prior to 12:00
Noon do not earn  accrued  interest  on the  redemption  date.  The wire for the
redemption  proceeds of shares redeemed  between 12:00 noon and the close of the
Exchange, which is normally 4:00 P.M., but may be earlier on some days, normally
will be transmitted by the Transfer Agent to the  shareholder's  designated U.S.
bank account on the next bank business day after the redemption. Shares redeemed
between  12:00 noon and the close of the Exchange  earn accrued  interest on the
redemption  date but no  interest is paid on the  proceeds  of  redeemed  shares
awaiting  transmittal by wire.  There is normally a $10.00 fee for Federal Funds
wire  redemption.  See  "Purchase,  Redemption  and  Pricing  of  Shares" in the
Statement of Additional Information for further details.

      o CHECKWRITING. Upon request, the Transfer Agent will provide any direct
shareholder  or  Program   participant  whose  shares  are  not  represented  by
certificates with forms of drafts ("checks")  payable through a bank selected by
the Fund (the  "Bank").  Program  participants  must  arrange  for  checkwriting
through  their  brokers or dealers.  The Transfer  Agent will arrange for checks
written by direct  shareholders  to be honored  by the Bank  after  obtaining  a
specimen signature card from the shareholder(s).  Shareholders of joint accounts
may elect to have checks  honored  with a single  signature.  Checks may be made
payable  to the  order of anyone  in any  amount  not less than $250 and will be
subject  to the Bank's  rules and  regulations  governing  checks.  For  Program
participants, checks will be drawn against the primary account designated by the
Program  participant.  If a check is  presented  for an amount  greater than the
account value,  it will not be honored.  Shares  purchased by check or Automatic
Investment  Plan  payments  within  the  prior  10 days may not be  redeemed  by
checkwriting.  A check  presented  to the Bank for  payment  that would  require
redemption of some or all of the shares so purchased is subject to  non-payment.
The Bank will present checks to the Fund to redeem shares to cover the amount of
the check.  Checks may not be  presented  for cash payment at the offices of the
Bank or the Fund's Custodian.  This limitation does not affect the use of checks
for the payment of bills or to obtain cash at other banks. The Fund reserves the
right to amend,  suspend  or  discontinue  checkwriting  privileges  at any time
without prior notice.

      o TELEPHONE REDEMPTIONS.  Direct shareholders of the Fund may redeem their
shares by telephone by calling the transfer Agent at 1-800-852-8457. Proceeds of
telephone  redemptions  will be paid by check payable to the  shareholder(s)  of
record and sent to the address of record for the account.  Telephone redemptions
are not  available  within 30 days of a change of the  address of record.  Up to
$50,000 may be redeemed by telephone in any seven day period.

      The Transfer Agent may record any calls.  Telephone redemptions may not be
available if all lines are busy, and  shareholders  would have to use the Fund's
regular redemption  procedures described above.  Telephone redemption privileges
are not available for  newly-purchased  (within the prior 10 days) shares or for
shares  represented  by  certificates.  Telephone  redemption  privileges  apply
automatically to each shareholder and the dealer representative of record unless
the Transfer  Agent  receives  cancellation  instructions  from a shareholder of
record.  If an account has multiple  owners,  the Transfer Agent may rely on the
instructions of any one owner.

      o  AUTOMATIC  WITHDRAWAL  PLANS.  Direct  shareholders  of  the  Fund  can
authorize the Transfer Agent to redeem shares (minimum $50)  automatically  on a
monthly,  quarterly,  semi-annual or annual basis under an Automatic  Withdrawal
Plan. Shares will be redeemed as of the close of the Exchange,  three days prior
to the date requested by the  shareholder  for receipt of the payment.  The Fund
cannot  guarantee  receipt of the payment on the date requested and reserves the
right to amend,  suspend or discontinue  offering such plans at any time without
prior  notice.  For  further  details,   refer  to  "Automatic  Withdrawal  Plan
Provisions" in the Statement of Additional Information.

GENERAL INFORMATION ON REDEMPTIONS.  The redemption price will be the Fund's net
asset value per share next  determined  after the Transfer  Agent's receipt of a
redemption  request in proper form.  Under certain  circumstances,  the Fund may
involuntarily  redeem  small  accounts if the account has fallen below $1,000 in
value.  For details,  see  "Purchase,  Redemption  and Pricing of Shares" in the
Statement  of  Additional  Information.  Payment  for  redeemed  shares  is made
ordinarily  in cash in U.S.  dollars  and  forwarded  within  seven  days of the
Transfer Agent's receipt of redemption instructions in proper form, except under
unusual  circumstances as determined by the Securities and Exchange  Commission.
The  Transfer  Agent may  delay  forwarding  a  redemption  check  for  recently
purchased  shares,  but only until the purchase payment has cleared.  That delay
may be as much as 10 days from the date shares were purchased. That delay may be
avoided if the  shareholder  purchases  shares by Federal Funds wire,  certified
check,  through a Program, or arranges with his or her bank to provide telephone
or written  assurance  to the  Transfer  Agent  that the  purchase  payment  has
cleared.  Shares purchased by check or Automatic Investment Plan payments within
the prior 10 days may not be redeemed by checkwriting.  A check presented to the
Bank for payment that would require the  redemption of some or all of the shares
so purchased is subject to non-payment. The Fund makes no charge for redemption.
Dealers or brokers may charge a fee for  handling  redemption  transactions  but
such charge can be avoided by  requesting  the  redemption  directly by the Fund
through the  Transfer  Agent.  Under  certain  circumstances,  the proceeds of a
redemption  of Fund shares  acquired  by  exchange  of shares of Eligible  Funds
purchased subject to a contingent  deferred sales charge ("CDSC") may be subject
to the CDSC. (See "Exchange Privilege" below).

EXCHANGES OF SHARES

EXCHANGE PRIVILEGE. Shares of the Fund held under a Program may be exchanged for
shares  of  Centennial  Money  Market  Trust,  Centennial  Government  Trust and
Centennial  Tax Exempt Trust  (collectively,  the  "Centennial  Trusts") only by
instructions of the broker. Shares of the Fund may, under certain circumstances,
be exchanged by direct  shareholders  for Class A shares of certain  Oppenheimer
funds (collectively  referred to as "Eligible Funds"). See "Exchanges of Shares"
in the Statement of  Additional  Information  for a list of the Eligible  Funds.
That list can change from time to time.

      There is an initial sales charge on the purchase of Class A shares of each
Eligible  Fund  except  Money  Market  Funds (as  defined  in the  Statement  of
Additional Information.) Under certain circumstances described below, redemption
proceeds of Money Market Fund shares may be subject to a CDSC.

      Shares of the Fund and of other  Eligible  Funds may be  exchanged  at net
asset value if all of the following  conditions  are met: (1) shares of the fund
selected for exchange are available for sale in the shareholder's state or other
jurisdiction  of residence;  (2) the respective  prospectuses of the funds whose
shares are to be  exchanged  and acquired  offer the  Exchange  Privilege to the
investor;  (3) newly-purchased  shares (by initial or subsequent investment) are
held in an  account  for at least  seven  days  prior to the  exchange;  (4) the
aggregate  net asset value of the shares  surrendered  for  exchange is at least
equal to the minimum investment  requirements of the fund whose shares are to be
acquired;  and (5) the investor is eligible to purchase shares of the fund to be
acquired.  Shares of the Fund may be  acquired  by  exchange  of shares of other
Eligible  Funds only if the  shareholder is an "eligible  foreign  investor," as
described  above under "How to Buy Shares"  and the  shareholder  submits a Form
W-8, a Special  Power of Attorney  form and Fund  Application  with the exchange
instructions.

     In addition to the conditions stated above, shares of Eligible Funds may be
exchanged for shares of any Money Market Funds;  shares of any Money Market Fund
(including  the Fund)  purchased  without a sales  charge may be  exchanged  for
shares of Eligible  Funds  offered with a sales charge upon payment of the sales
charge (or, if  applicable,  may be used to  purchase  shares of Eligible  Funds
subject  to a  CDSC);  and  shares  of the  Fund  acquired  by  reinvestment  of
distributions  from any Eligible Fund except  Oppenheimer  Cash Reserves or from
any unit investment  trust for which  reinvestment  arrangements  have been made
with the Distributor or Sub-Distributor  may be exchanged at net asset value for
shares of any  Eligible  Fund.  The  redemption  proceeds of shares of the Fund,
acquired by exchange of Class A shares of an Eligible Fund purchased  subject to
a CDSC,  that are redeemed  within 12 months of the end of the calendar month of
the initial  purchase of the  exchanged  shares (18 months for shares  purchased
prior to May 1, 1997) will be subject to the CDSC as described in the prospectus
of that other Eligible Fund. In determining whether the CDSC is payable,  shares
of the  Fund  not  subject  to the CDSC are  redeemed  first,  including  shares
purchased by reinvestment of distributions and capital gains  distributions from
any  Eligible  Fund or  shares of the Fund  acquired  by  exchange  of shares of
Eligible Funds on which a front-end sales charge was paid or credited,  and then
other shares are redeemed in the order of purchase.

HOW TO  EXCHANGE  SHARES.  An  exchange  may be made by direct  shareholders  by
submitting an Exchange  Authorization Form to the Transfer Agent,  signed by all
registered  owners.  In addition,  direct  shareholders of the Fund may exchange
shares  of the  Fund for  shares  of any  Eligible  Fund by  telephone  exchange
instructions to the Transfer Agent by a shareholder or the dealer representative
of record for an  account.  The Fund may  modify,  suspend or  discontinue  this
exchange  privilege  at any time.  Although  the Fund will  attempt  to  provide
shareholders with notice whenever  reasonably able to do so, it may impose these
changes at any time.  The Fund  reserves the right to reject  exchange  requests
submitted in bulk on behalf of 10 or more  accounts.  Exchange  requests must be
received  by the  Transfer  Agent by the  close  of the  Exchange  on a  regular
business day to be effected that day. The number of shares exchanged may be less
than the number  requested if the number  requested would include shares subject
to a  restriction  cited above or shares  covered by a  certificate  that is not
tendered  with such  request.  Only the shares  available  for exchange  without
restriction will be exchanged.

TELEPHONE EXCHANGES.  Direct shareholders may place a telephone exchange request
by calling the Transfer Agent at 1-800-852-8457. Telephone exchange calls may be
recorded by the Transfer  Agent.  Telephone  exchanges  are subject to the rules
described  above.  By  exchanging  shares  by  telephone,   the  shareholder  is
acknowledging  receipt of a prospectus of the fund to which the exchange is made
and that for full  exchanges,  any special  account  features  such as Automatic
Investment  Plans and  Automatic  Withdrawal  Plans will be  switched to the new
account unless the Transfer Agent is otherwise  instructed.  Telephone  exchange
privileges  automatically  apply to each  direct  shareholder  of record and the
dealer  representative  of record unless and until the Transfer  Agent  receives
written   instructions   from  the   shareholder(s)  of  record  canceling  such
privileges.  If an account has multiple  owners,  the Transfer Agent may rely on
the instructions of any one owner.

      The Transfer Agent reserves the right to require  shareholders to confirm,
in writing,  telephone  exchange  privileges for an account.  Shares acquired by
telephone  exchange  must be  registered  exactly as the account  from which the
exchange was made.  Certificated shares are not eligible for telephone exchange.
If all telephone exchange lines are busy (which might occur, for example, during
periods of substantial market  fluctuations),  shareholders might not be able to
request telephone exchanges and would have to submit written exchange requests.

GENERAL INFORMATION ON EXCHANGES. Shares to be exchanged are redeemed on the day
the Transfer Agent receives an exchange  request in proper form (the "Redemption
Date") as of the close of the Exchange,  which is normally 4:00 P.M., but may be
earlier on some days. Normally,  shares of the fund to be acquired are purchased
on the  Redemption  Date, but such purchases may be delayed by either fund up to
five  business  days if it  determines  that it  would  be  disadvantaged  by an
immediate transfer of the redemption proceeds. The Fund, in its sole discretion,
reserves the right to refuse any exchange request that may disadvantage it.

      The Eligible  Funds have  investment  objectives  and policies that differ
from those of the Fund,  are not  designed  solely for  foreign  investors,  and
therefore are not subject to the same tax  considerations  as the Fund and their
dividends  and  distributions  paid to  foreign  shareholders  may be subject to
withholding  of U.S.  Federal  income tax.  Each of those funds  imposes a sales
charge on  purchases  of Class A shares  except  the  Money  Market  Funds.  For
complete information,  including sales charges and expenses, a prospectus of the
fund into which the  exchange is being made should be read prior to an exchange.
Dealers or brokers who process exchange orders on behalf of customers may charge
for their services.  Direct  shareholders  may avoid those charges by requesting
the Fund directly to exchange shares.  For Federal tax purposes,  an exchange is
treated as a redemption and purchase of shares.

TELEPHONE  INSTRUCTIONS.  The Transfer Agent has adopted  procedures  concerning
telephone  transactions  including  confirming that telephone  instructions  are
genuine by  requiring  callers to provide tax  identification  numbers and other
account data or by using PINs and by recording  telephone  calls and  confirming
such  transactions  in  writing.  If  the  Transfer  Agent  does  not  use  such
procedures,  it may be liable for losses due to unauthorized  transactions,  but
otherwise  neither it nor the Fund will be liable for losses or expenses arising
out of any telephone  instructions the Transfer Agent reasonably  believes to be
genuine.

SHAREHOLDER  TRANSACTIONS BY FAX. Requests for certain account transacations may
be sent to the Transfer Agent by fax  (telecopier).  Please call  1-800-525-9310
for information  about which  transactions  are included.  Transaction  requests
submitted by fax are subject to the same rules and  restrictions  as written and
telephone requests described in this Prospectus.

DISTRIBUTIONS AND TAXES

DISTRIBUTIONS. The Fund intends to declare daily distributions of all of its net
investment  income, as defined below, each regular business day, and to pay such
distributions  monthly,  on a date set by the Managing General  Partners,  which
will normally be the third Thursday of each month.  Such  distributions  will be
payable  to  shareholders  as set  forth  in "How to Buy  Shares,"  above.  If a
shareholder  redeems  all  shares  at any time  during a month,  the  redemption
proceeds  include   distributions  accrued  up  to  the  redemption  date.  Such
redemption proceeds will include all distributions  accrued up to the redemption
date for shares  redeemed  prior to 12:00 noon,  and  include all  distributions
accrued through the redemption  date for shares redeemed  between 12:00 noon and
the close of the Exchange,  which is normally  4:00 P.M.,  but may be earlier on
some days.

      All   distributions   for  the  accounts  of  Program   participants   are
automatically  reinvested  in  additional  shares  of  the  Fund.  Distributions
accumulated  since the prior  payment will be  reinvested on the payment date in
full and  fractional  shares of the Fund at net asset value.  Such investors may
receive cash  payments by asking the broker to redeem  shares.  Participants  in
Programs will receive account statements  directly from their dealers reflecting
any account activity.  Under the terms of a Program, a broker-dealer may pay out
the  value  of some or all of a  Program  participant's  Fund  shares  prior  to
redemption of such shares by the Fund. In such cases,  the  shareholder  will be
entitled to  distributions  on such shares only up to and  including the date of
such payment.  Distributions on such shares accruing between the date of payment
and  the  date  such  shares  are  redeemed  by the  Fund  will  be  paid to the
broker-dealer.  It is anticipated  that such payments will occur only to satisfy
debit balances arising in a shareholder's account under a Program.

     Distributions  payable  to  direct  shareholders  of the Fund  will also be
automatically reinvested in shares of the Fund at net asset value on the payment
date,  unless  the  shareholder  asks  the  Transfer  Agent  in  writing  to pay
distributions in cash or to reinvest them in another Eligible Fund, as described
in  "Reinvestment  of  Distributions  in  Another  Fund"  in  the  Statement  of
Additional Information. The minimum initial and subsequent purchase requirements
are waived as to such purchases.  Distributions  and the proceeds of redemptions
of Fund shares  represented by checks returned to the Fund by the Postal Service
as  undeliverable  will be  reinvested  in shares of the Fund,  as  promptly  as
possible  after the return of such  checks to the  Transfer  Agent to enable the
investor to earn a return on otherwise idle funds.

      The Fund's net investment income for distribution purposes consists of all
interest  accrued on  portfolio  assets,  less all expenses of the Fund for such
period. Accrued market discount is included in interest income; amortized market
premium is treated as an expense. Although distributions from net realized gains
on  securities,  if any,  will be paid at least once each year,  and may be made
more frequently, the Fund does not expect to realize long-term capital gains and
therefore  does not  contemplate  payment  of any  capital  gains  distribution.
Distributions  from net realized gains will not be distributed unless the Fund's
capital loss carry forwards,  if any, have been used or have expired.  To effect
its policy of maintaining a net asset value of $1.00 per share,  the Fund, under
certain  circumstances,  may withhold  distributions or make  distributions from
capital or capital gains.

TAXES. The discussion below relates principally to U.S. Federal income tax laws.
Distributions  may be subject to state and local taxation and taxation under the
laws of foreign countries. The value of Fund shares owned directly by a non-U.S.
citizen  may be subject to U.S.  (and  possibly  state)  estate  taxes upon such
investor's  death,  subject  to  certain  exemptions  and  to the  terms  of any
applicable tax treaty between the U.S. and the investor's  country of residence.
The tax  consequences of investing in the Fund will depend upon the jurisdiction
in which the investor is subject to taxation.  The  discussion  below  assumes a
shareholder of the Fund generally is not subject to U.S. tax or withholding with
respect to other income or  activities  unrelated to an  investment in the Fund;
otherwise, the discussion below may not apply.  Distributions from the Fund will
not be eligible for the distributions-received  deduction for corporations under
the Internal Revenue Code.  Shareholders  should consult a qualified tax advisor
since the discussion below is only a summary and is not exhaustive.

     Because shareholders are limited partners of the Fund,  consistent with the
Fund's Partnership Agreement, each shareholder will be allocated a proportionate
share of any net income and realized  gains (or losses) for U.S.  Federal income
tax purposes  even if not  distributed.  Allocations  of items of income,  gain,
loss,  deduction and credit of the Fund for U.S. Federal income tax purposes are
made in a manner intended to reflect each shareholder's  respective  interest in
the Fund.  While there can be no assurance that the tax allocations  made by the
Fund will be  respected  by the United  States  Internal  Revenue  Service  (the
"IRS"),  the  allocations  are  made in a manner  intended  to  approximate  the
economic experience of each shareholder,  as a limited partner,  with respect to
such shareholder's investment in the Fund. After each calendar year, the Fund is
required to send  shareholders  (regardless  of whether they are or are not U.S.
taxpayers) and to file with the IRS a U.S. Federal tax form (Form 1065, Schedule
K-1)  which  identifies  their  share of net  income,  gains and  losses for the
taxable year. The Fund will also file an annual  information return with the IRS
with respect to each non- U.S.  shareholder  (which includes,  as an attachment,
the Form W-8 furnished by the shareholder)  indicating,  if applicable,  that no
amount was withheld with respect to income  allocated to such  shareholder  that
qualified  for  the  "portfolio  interest"  exemption  or any  other  applicable
exemption  under the  Internal  Revenue  Code.  The Fund may be required to send
shareholders  additional  forms under  certain  circumstances,  for example Form
1042S.  Shareholders  should consult their tax advisors  regarding any tax forms
received from the Fund.

TAX STATUS OF THE FUND.  The Fund intends to comply with the  provisions  of the
Internal  Revenue Code  applicable to limited  partnerships,  and has obtained a
ruling from the IRS that the Fund will be classified  as a partnership  and that
its general and limited  partners will be treated as partners for Federal income
tax   purposes.   See  "Federal  Tax   Legislation   Affecting   Publicly-Traded
Partnerships".

      As a limited  partnership,  the Fund is not subject to U.S. Federal income
tax, and the  character of any income  earned or capital  gains  realized by the
Fund  flows  through  directly  to its  shareholders.  Shareholders  of the Fund
generally  are liable  for  payment  of taxes on their  allocated  share of fund
income  and  realized  capital  gains.  However,  to the  extent  the Fund earns
"portfolio  interest" income,  eligible foreign investors who are not subject to
payment or  withholding  of U.S.  tax on these types of income are  likewise not
subject to payment or withholding of U.S. tax on their  allocated share of these
types of income from the Fund, subject to the conditions stated below.

      Although a ruling from the IRS has been obtained, foreign investors should
note that the IRS or the U.S.  courts  may  ultimately  determine  that the Fund
should be  characterized at all times for U.S. Federal income tax purposes as an
association   taxable  as  a   corporation,   rather  than  as  a   partnership.
Characterization of the Fund as an association taxable as a corporation for U.S.
Federal income tax purposes will result in the imposition of both a U.S. Federal
corporate  income tax on earnings of the Fund and the imposition of U.S. Federal
income tax and withholding on distributions to the limited partners of the Fund
because such distributions would be characterized as "distributions"  subject to
withholding  tax rather  than as interest  income  eligible  for the  "portfolio
interest" exemption and capital gains.

     o  FEDERAL  TAX   LEGISLATION   AFFECTING   PUBLICLY-TRADED   PARTNERSHIPS.
Subsequent  to the  Fund's  receipt  of a  ruling  from the IRS that it would be
classified as a partnership  and that its general and limited  partners would be
treated as partners  for Federal  income tax  purposes,  the Revenue Act of 1987
("1987 Act") was signed into law on December 22, 1987.  Under  provisions of the
1987  Act,  "publicly-traded"   partnerships  were  generally  characterized  as
corporations rather than partnerships for Federal income tax purposes.  However,
because the Fund was in  existence  on December  17,  1987,  it  qualified as an
"existing partnership" under certain "grandfathering" provisions of the 1987 Act
and, as such,  continued to be treated as a partnership  for Federal  income tax
purposes thereafter. The "grandfathering" provisions of the 1987 Act were set to
expire on December 31, 1997, and it was anticipated that "existing partnerships"
would be classified as  associations  taxable as  corporations  as of January 1,
1998.

      The Taxpayer Relief Act of 1997 permits a publicly-traded partnership that
was in existence on December 17, 1987 and that  continues to meet certain  other
criteria, to elect to continue its

status as a partnership for U.S. Federal income tax purposes for tax years after
December  31,  1997.  The Fund has made  this  election.  As an  "electing  1987
partnership,"  the Fund will seek to maintain  its  treatment  as a  partnership
rather than become taxable as corporation  for tax years after December 31, 1997
by paying a tax equal to 3.5% of its gross  income  and  meeting  certain  other
criteria.

TAX  CONSIDERATIONS  FOR FUND INVESTORS.  A foreign  investor (i.e., an investor
other than a U.S. citizen or resident or a U.S. corporation, partnership, estate
or trust) who is engaged in a trade or  business  in the United  States  will be
subject to U.S.  Federal income tax on any ordinary  income and capital gains at
the same rates  applicable to U.S. persons on the foreign  investor's  allocable
share of ordinary  income and capital  gains  realized by the Fund to the extent
such income and gains are deemed to be effectively connected with the conduct of
such foreign  investor's trade or business and U.S.  taxation of such income and
gains is not avoided  under the terms of an applicable  U.S.  income tax treaty.
For this purpose,  foreign  investors will be deemed to be engaged in a trade or
business  in the U.S.  and will be subject to U.S.  Federal  income tax on their
allocable  share of the Fund's net  income  and  capital  gains if the Fund were
deemed to be engaged in a trade or  business in the U.S. If the Fund were deemed
to be engaged in a trade or business  in the U.S.,  it would also be required to
withhold U.S.  Federal income tax at the maximum rate applicable to the investor
on income earned. The Fund has obtained an opinion of counsel to the effect that
neither the Fund nor its investors,  solely by virtue of their investment in the
Fund, should be deemed to be engaged in a trade or business in the United States
if  the  Fund  adheres  to  its  stated  investment   objective,   policies  and
restrictions and to certain guidelines concerning its investment activities. The
Fund intends to comply with those restrictions and guidelines. Consequently, any
foreign  investor  in the Fund  should not be deemed to be engaged in a trade or
business in the United  States  solely by virtue of an  investment  in the Fund.
Although the Fund and its tax counsel  rendering such opinion believe that their
position is fully  supported by applicable  law,  there can be no assurance that
the IRS or a court of law would  not take a  contrary  position.  If the Fund is
deemed to be engaged in a U.S.  trade or  business  by a court of law,  then its
portfolio  interest  would be  subject to U.S.  Federal  income tax and the Fund
would be obligated to withhold tax on all income allocated to shareholders.

      Assuming that a foreign investor  purchasing Fund shares is not engaged in
a trade or  business in the United  States,  such  investor's  share of ordinary
income  realized  by the Fund will not be  subject  to U.S.  Federal  income tax
(including  withholding of such taxes),  if (i) the ordinary  income consists of
interest  income which  qualifies for the "portfolio  interest"  exemption under
Sections  871(h) and  881(c) of the  Internal  Revenue  Code,  (ii) the  foreign
investor has furnished a valid and effective IRS Form W-8 (or  substitute  form)
to the Fund,  (iii) the Fund has no actual  knowledge  that the  investor is, in
fact, a U.S. person, and (iv) the investor properly  certifies,  if so required,
that the beneficial owner of such investment is not (a) a "10%  shareholder" (as
defined in Section  871(h)(3) of the Code) of the issuer of the security held by
the  Fund  which  generates  the  interest  income,  (b)  a  controlled  foreign
corporation  related to such issuer,  or (c) a bank deemed to be receiving  such
interest  (other than  interest  on an  obligation  of the United  States) on an
extension  of credit  made  pursuant  to a loan  agreement  entered  into in the
ordinary  course  of its  trade or  business.  The Fund  has been  advised  that
interest  income will qualify for the  "portfolio  interest"  exemption if it is
paid with respect to a publicly-offered, registered debt obligation issued after
July 18, 1984, with respect to which the Fund, which would otherwise be required
to withhold U.S.  Federal  income tax from such interest  under Sections 1441 or
1442 of the Internal Revenue Code, has received a valid and effective  statement
(such as that  contained in the  Application  and Form W-8) that the  beneficial
owner of the obligation is not a U.S.  person.  It should be noted that interest
income  received by the Fund on certain  short-term  investments may not qualify
for  the  "portfolio  interest"  exemption.  Accordingly,  the  portion  of such
interest  allocable  to foreign  shareholders  would be subject to U.S.  Federal
income tax (including  withholding taxes) during the calendar year such interest
is received by the Fund.

      A non-U.S.  investor  who is not  "engaged in a trade or  business" in the
United States for purposes of the Internal  Revenue Code  generally  will not be
subject to U.S. Federal income tax (or withholding) on that investor's allocated
share of net  short-term  or  long-term  capital  gains  realized  by the  Fund,
provided  that, in the case of an investor who is a person,  the investor is not
physically  present in the U.S. for 183 or more days during the year or for such
other period as would cause the investor to be treated as a U.S.  resident under
the Internal  Revenue Code.  Proceeds of redemption of Fund shares also will not
be subject to U.S. tax if they  constitute  non-U.S.  source income by virtue of
the  investor's  non-U.S.  status.  However,  even  if  the  proceeds  of  share
redemptions are not subject to U.S. tax under such rules, the Fund  nevertheless
may be required to withhold on the portion of such proceeds that  represents the
investor's  allocable  share of income or gains of the Fund that would otherwise
be subject to withholding.

      Foreign  investors  who do not furnish a valid and  effective  Form W-8 or
otherwise  properly  certify,  if required by U.S.  Federal tax laws,  that such
investor  is  not  (a) a "10  percent  shareholder",  (b) a  controlled  foreign
corporation  of the issuer,  or (c) a bank deemed to be receiving  such interest
(other than interest on an  obligation of the United  States) on an extension of
credit made pursuant to a loan agreement  entered into in the ordinary course of
its  trade  or  business  may be  subject  to U.S.  withholding  taxes  on their
allocated  shares of all income realized by the Fund (regardless of its source).
Foreign  shareholders  are  required to furnish a Form W-8 every three  calendar
years. As previously discussed, regardless of whether a valid and effective Form
W-8 is furnished,  foreign shareholders may be subject to U.S. withholding taxes
on their allocated shares of income realized by the Fund from sources other than
"portfolio   interest"  income  and  net  realized  capital  gains  unless  such
withholding  taxes are reduced or  eliminated  under the terms of an  applicable
U.S.  income  tax treaty  and the  investor  complies  with all  procedures  for
claiming  the  benefits  of such a treaty.  It is the  intention  of the Fund to
withhold  amounts  required  by  the  Internal  Revenue  Code  with  respect  to
non-qualifying income and/or nonqualifying investors.
