                          WARBURG PINCUS TAX FREE FUND
                                       OF
                               THE RBB FUND, INC.
    

                             Your Vote is Important



Dear Shareholder:

The Board of  Directors  of The RBB Fund,  Inc.  (the "RBB  Fund") has  recently
reviewed and unanimously  endorsed  proposals for the reorganization of three of
its  investment  series -- Warburg  Pincus Growth & Income Fund,  Warburg Pincus
Balanced Fund and Warburg Pincus Tax Free Fund (each, an "Existing Warburg Fund"
and, collectively,  the  "Existing  Warburg  Funds").  Under  the  terms  of the
proposals,  each of three newly-formed  investment companies -- Warburg,  Pincus
Growth & Income Fund,  Inc.,  Warburg,  Pincus  Balanced Fund, Inc. and Warburg,
Pincus Tax Free Fund, Inc. (each, a "New Warburg Fund",  and  collectively,  the
"New Warburg Funds") -- would acquire all or substantially all of the assets and
liabilities of the Existing  Warburg Fund with a similar name. We are pleased to
invite you to attend a special  meeting (the  "Meeting") of the  shareholders of
each Existing Warburg Fund to consider the approval of a Plan of  Reorganization
(the  "Plan")   pursuant  to  which  the   reorganization   of  your  Fund  (the
"Reorganization") would be effected.

Your Board of Directors and Warburg, Pincus Counsellors,  Inc. ("Warburg"), each
Fund's  investment  adviser,  believe  that  the  Reorganization  is in the best
interests of each Existing Warburg Fund and its shareholders.  It will integrate
the Existing Warburg Funds fully into the Warburg Pincus Funds family,  thereby,
among other  things,  reducing  confusion  in the  marketplace  and reducing the
possibility  of  inconsistencies  in  operations,   and  may  generate  economic
efficiencies as well.

The Reorganization  will not result in any changes to the investment  philosophy
or operations of your Fund,  since each New Warburg Fund has the same investment
objective and  substantially  similar  investment  policies as the corresponding
Existing  Warburg  Fund.  Each New  Warburg  Fund will have the same  investment
adviser,  administrators,  custodian  and  transfer  agent as the  corresponding
Existing  Warburg Fund. In addition,  Counsellors  Securities  Inc. (each Fund's
distributor) and PFPC Inc. (each Fund's co-administrator) (or their affiliates),
have  agreed  to waive  fees and  reimburse  expenses  for the  one-year  period
following the closing of the  Reorganization  (the "Closing Date") to the extent
necessary  for the net expense  ratio of each New  Warburg  Fund to be no higher
than that of the corresponding Existing Warburg Fund on the Closing Date.



<PAGE>


If shareholders of an Existing Warburg Fund approve the Plan, upon  consummation
of  the  Reorganization  of  that  Fund,  the  Existing  Warburg  Fund  will  be
liquidated. You will become a shareholder of the corresponding New Warburg Fund,
having  received  shares of the same class with an aggregate  value equal to the
aggregate net asset value of your investment in the Existing Warburg Fund at the
time of the transaction. No sales charge will be imposed in the transaction. The
transactions will, in the opinion of counsel,  be free from federal income taxes
to you, the Existing  Warburg  Funds and the New Warburg  Funds.  Warburg or its
affiliates   will  bear  all   expenses   incurred  in   connection   with  each
Reorganization.

The  Meeting  will be  held on May 1,  1996 to  consider  this  transaction.  We
strongly invite your participation by asking you to review,  complete and return
your proxy promptly. If you own shares of more than one Existing Warburg Fund, a
separate proxy card is enclosed for each.
   
Detailed  information  about the  proposed  reorganization  is  described in the
attached  combined  prospectus/proxy  statement.  YOUR  BOARD OF  DIRECTORS  HAS
UNANIMOUSLY  APPROVED  THE  REORGANIZATION  OF EACH  EXISTING  WARBURG  FUND AND
RECOMMENDS  THAT YOU  VOTE TO  APPROVE  THE  PLAN.  On  behalf  of the  Board of
Directors,  I thank you for your  participation as a shareholder and urge you to
please  exercise  your  right to vote by  completing,  dating  and  signing  the
enclosed  proxy  card(s).  A  self-addressed,  postage-paid  envelope  has  been
enclosed  for your  convenience;  if you  prefer,  you can fax the proxy card to
Dominick Maurillo at (212) 809-8839.

If you have any  questions  regarding the proposed  reorganization,  please call
1-800-755-3107, where an individual will be pleased to assist you.
    
IT IS VERY IMPORTANT THAT YOUR VOTING INSTRUCTIONS BE RECEIVED PROMPTLY.

                                   Sincerely,


   
                                Donald van Roden
                              Chairman of the Board

                   Warburg Pincus Funds-Questions and Answers



Q.)      What issues am I being asked to vote on?

A.)      You are  being  asked to  approve  a  proposed  Reorganization  of your
         Existing  Warburg  Fund.  As a result of the  Reorganization,  you will
         receive shares of identical value in a  corresponding  New Warburg Fund
         with the same name,  investment  objective and portfolio  manager(s) as
         your Existing Warburg Fund.

Q.)      Is the proposed Reorganization in my best interest?


A.)      Yes. Your Board of Directors  and Warburg,  Pincus  Counsellors,  Inc.,
         believes  that  the  Reorganization  is in the best  interests  of each
         Existing  Warburg  Fund and its  shareholders.  It will  integrate  the
         Existing  Warburg  Funds fully into the Warburg  Pincus  Funds  family,
         thereby, among other things,  reducing confusion in the marketplace and
         reducing the possibility of inconsistencies in operations. The interest
         of the  shareholders of the Existing  Warburg Funds will not be diluted
         as a result of the Reorganization.

Q.)      Will there be any changes in the investment objectives as a result of
         the proposed Reorganization?

A.)      The  Reorganization  will not result in any  changes to the  investment
         philosophy or operations of your Fund,  since each New Warburg Fund has
         the same investment  objective as the  corresponding  Existing  Warburg
         Fund.  Each New Warburg Fund will have the same  portfolio  manager(s),
         administrators,  custodian  and  transfer  agent  as the  corresponding
         Existing Warburg Fund.

Q.)      Are there any federal income tax consequences as a result of the
         proposed Reorganization?

A.)      No.  As a result of the Reorganization, no gain or loss will be
         recognized by the Existing Warburg Fund or its shareholders for
         federal income tax purposes.

Q.)      Who will bear the costs associated with the proposed Reorganization?

A.)      Warburg or its affiliates will bear all expenses incurred in
         connection with each Reorganization.



<PAGE>2




Q.)      Is it going to cost me more money because of the Reorganization?

A.)      No.  As indicated in the proxy material, there is no change in fees
         or expenses.

Q.)      How do I vote my shares?

A.)      You can vote your shares by signing, dating and mailing the enclosed
         proxy card in the postage paid envelope.  If you have any questions
         or need any assistance please call our proxy solicitor, D.F. King &

                  This Combined Prospectus/Proxy Statement is being furnished
to shareholders  of Warburg  Pincus  Growth & Income Fund  (the  "Existing
Growth & Income Fund"),  Warburg Pincus Balanced Fund (the "Existing  Balanced
Fund") and Warburg  Pincus Tax Free Fund (the  "Existing Tax Free Fund,"
together with the Existing Growth & Income Fund and Existing Balanced Fund,
the "Existing Warburg Funds", each an "Existing Warburg Fund"), separate
series of The RBB Fund, Inc.  (the "RBB Fund"),  in  connection  with proposed
plan of  reorganization  (the "Plan") to be  submitted  to shareholders  of
each  Existing  Warburg  Fund for consideration  at a Special Meeting of
Shareholders to be held on May 1, 1996 at 3:00 p.m. (the "Meeting"),  at the
offices of The RBB Fund, Inc.  located at 400 Bellevue Parkway, Wilmington,
Delaware 19809, or any adjournment or adjournments thereof.
    
                  Each of Warburg, Pincus Growth & Income Fund, Inc. (the "New
Growth & Income Fund"), Warburg, Pincus Balanced Fund, Inc. (the "New Balanced
Fund") and Warburg, Pincus Tax Free Fund, Inc. (the "New Tax Free Fund" and,
with the New Growth & Income Fund and the New Balanced Fund, the "New Warburg
Funds"; each a "New Warburg Fund") is a newly organized registered investment
company.

                  The  proposed  reorganization  pursuant  to the Plans will
not result in any change in the investment  philosophy or operations of the

<PAGE>2


Existing Warburg Funds.  The investment  objectives and policies of each New
Warburg Fund are the same as those of the  corresponding  Existing  Warburg
Funds except for minor investment  policy  differences  described under
"Comparison of Investment Objectives  and  Policies"  in this  Combined
Prospectus/Proxy  Statement.  The investment adviser, administrators,
custodian, transfer agent and accountant for each New  Warburg  Fund are the
same as  those  of the  corresponding  Existing Warburg Fund.

                  The Plan provides for all or  substantially  all of the
assets of an Existing Warburg Fund to be acquired by the corresponding New
Warburg Fund in exchange  for shares of the New Warburg Fund and the
assumption  by such New Warburg  Fund of  liabilities  of the  Existing
Warburg  Fund (as regards  each Existing Warburg Fund,  hereinafter referred
to as the  "Reorganization").  (The New Warburg  Funds and the  Existing
Warburg  Funds are  sometimes  referred to hereinafter  as the  "Funds"  and
individually  as a  "Fund.")  Shares of a New Warburg Fund would be
distributed to shareholders of the corresponding  Existing Warburg  Fund in
liquidation  of the  corresponding  Existing  Warburg Fund and thereafter  the
Existing  Warburg Fund would be  terminated.  As a result of the proposed
Reorganization,  each  shareholder  of an Existing  Warburg  Fund will receive
that number of shares of the  corresponding  New Warburg Fund having an
aggregate  net asset value equal to the  aggregate  value of such
shareholder's shares of the Existing Warburg Fund immediately prior to the
Reorganization. All expenses of the  Reorganization  will be borne by Warburg,
Pincus  Counsellors, Inc.  ("Warburg"  or the  "Adviser"),  the  investment
adviser of each Existing Warburg Fund and each New Warburg  Fund.  No sales
charge will be imposed on the shares of a New Warburg Fund received by the
shareholders of the  corresponding Existing Warburg Fund. This transaction is
structured to be tax-free for federal income tax purposes to  shareholders
and to both the New Warburg  Funds and the Existing Warburg Funds.
   
                  This  Combined  Prospectus/Proxy  Statement,  which  should
be retained for future  reference,  sets forth concisely the information

voting.  This Combined Prospectus/Proxy Statement is expected to first be sent

                                 SUMMARY
   
         THIS  SUMMARY  IS  QUALIFIED  IN  ITS  ENTIRETY  BY  REFERENCE  TO
THE ADDITIONAL  INFORMATION  CONTAINED  ELSEWHERE IN THIS COMBINED
PROSPECTUS/PROXY STATEMENT,  THE PLAN,  A COPY OF THE FORM OF WHICH IS
ATTACHED TO THIS  COMBINED PROSPECTUS/PROXY  STATEMENT  AS  EXHIBIT  A, THE
PROSPECTUSES  OF THE  EXISTING WARBURG FUNDS DATED DECEMBER 29, 1995, THE
STATEMENTS OF ADDITIONAL  INFORMATION OF THE EXISTING  WARBURG FUNDS DATED
DECEMBER 29, 1995, THE  PROSPECTUSES OF THE NEW  WARBURG  FUNDS  DATED  MARCH
4,  1996  AND  THE STATEMENTS  OF  ADDITIONAL INFORMATION OF THE NEW WARBURG
FUND DATED MARCH 4, 1996.
    
                  PROPOSED REORGANIZATION.  The Plan provides for the transfer
of all or substantially all of the assets and liabilities of each Existing
Warburg Fund to the corresponding New Warburg Fund in exchange for shares of
the New Warburg Fund.  The Plan also calls for the distribution of shares of a
New Warburg Fund to the corresponding Existing Warburg Fund's shareholders in
liquidation of the Existing Warburg Fund.  (The foregoing proposed
transactions as regards each Existing Warburg Fund are referred to in this
Combined Prospectus/Proxy Statement as the "Reorganization").  As a result of
the Reorganization, each shareholder of an Existing Warburg Fund will become
the owner of that number of full and fractional shares of the same class of
the corresponding New Warburg Fund having an aggregate net asset value equal
to the aggregate value of the shareholder's shares of the Existing Warburg
Fund as of the close of business on the date that each Existing Warburg Fund's
assets are exchanged for shares of the corresponding New Warburg Fund.
Holders of common shares of the Existing Warburg Fund will become holders of
common shares of the corresponding New Warburg Fund and holders of Advisor
Shares of the Existing Warburg Fund will become holders of Advisor Shares of
the corresponding New Warburg Fund.  See "Information About the Reorganization
- -- Plan of Reorganization."

                  For  the  reasons  set  forth  below  under  "Reasons  for
the Reorganization," the Board of Directors of the RBB Fund, including the
Directors of the RBB Fund who are not "interested persons" (the "Independent
Directors"), as that term is defined in the  Investment  Company Act of 1940,
as amended (the "1940 Act"), has unanimously  concluded that the
Reorganization  would be in the best interests of the  shareholders  of each
Existing  Warburg Fund and that the interests of each Existing  Warburg
Fund's  existing  shareholders  will not be diluted as a result of the
transaction  contemplated by the Reorganization.  The Board  therefore has
submitted  the Plan for approval by each Existing  Warburg Fund's
shareholders. The Board of Directors of each New Warburg Fund has reached
similar  conclusions  with respect to the New Warburg Fund and has also approved
the Reorganization with respect to the New Warburg Fund.

                  Approval of the Reorganization of an Existing Warburg Fund
will require the affirmative vote of the holders of a majority of that
Existing Warburg Fund's outstanding shares.  See "Voting Information." No


<PAGE>7

Reorganization of any Existing Warburg Fund is contingent on the approval
and/or closing of the Reorganization of any other Existing Warburg Fund.
In the event that the Plan is not approved by shareholders of one or more
Existing Warburg Funds, the Board will consider what other course of action,
if any, should be taken.

                  TAX  CONSEQUENCES.  Prior to completion of the
Reorganization, each  Existing  Warburg  Fund and its  corresponding  New
Warburg Fund will have received an opinion of counsel that, upon the closing
of the  Reorganization and the transfer of the assets of such  Existing
Warburg Fund, no gain or loss will be  recognized  by the  Existing  Warburg
Fund or its  shareholders  for federal income  tax  purposes.  The  holding
period  and  aggregate  tax  basis  of the corresponding  New Warburg  Fund's
shares  received by an Existing  Warburg Fund shareholder  will be the same as
the holding  period and  aggregate tax basis of the shares of the Existing
Warburg Fund previously held by such shareholder.  In addition,  the  holding
period  and tax basis of the  assets  of each  Existing Warburg Fund in the
hands of the  corresponding  New Warburg Fund as a result of the
Reorganization will be the same as in the hands of the Existing Warburg Fund
immediately prior to the Reorganization.

                  INVESTMENT OBJECTIVES AND POLICIES.  Each New Warburg Fund
was organized for the purpose of acquiring the assets of the corresponding
Existing Warburg Fund and each New Warburg Fund will have the same investment
objective, and, except as noted below under "Comparison of Investment
Objectives and Policies", the same investment policies and limitations as the
corresponding Existing Warburg Fund.

                  PURCHASE AND REDEMPTION PROCEDURES.  The purchase and
redemption procedures available to shareholders of each New Warburg Fund are
virtually identical to those available to shareholders of the corresponding
Existing Warburg Fund.  Purchases of shares of each New Warburg Fund and the
corresponding Existing Warburg Fund may be made by mail, or with advance
arrangements, by wire through the Funds' distributor, Counsellors Securities
Inc. ("CSI").  Shares of the Funds are sold at net asset value per share and
without a sales charge.  Common Shares of the New and Existing Balanced and
Tax Free Funds are subject to a 12b-1 fee of .25% per annum.  Advisor Shares
of the New and Existing Growth & Income and Balanced Funds are subject to a
12b-1 fee of up to .75% per annum.

                  EXCHANGE PRIVILEGES.  The exchange privileges available to
shareholders of each New Warburg Fund are identical to those available to
shareholders of the corresponding Existing Warburg Fund.  Shareholders of each
Existing Warburg Fund and the corresponding New Warburg Funds may exchange at
net asset value all or a portion of their shares for shares of the same class
of certain other mutual funds advised by Warburg at their respective net asset
values.  However, shareholders may not effect exchanges between Common Shares
and Advisor Shares.  Exchanges may be effected by mail or by telephone.
Exchanges will be effected without a sales charge but must satisfy the minimum
dollar amount necessary for new purchases.  Due to the costs involved in
effecting exchanges, each Fund reserves the right to refuse to honor more than
three exchange requests by a shareholder in any 30-day period.  The exchange
privilege may be modified or terminated at any time upon 60 days' notice to
shareholders.  Currently, Common Share exchanges may be made among the Funds
with Common Shares of the following other Warburg Pincus Funds:

                  An institutional shareholder of record and certain other
financial intermediaries may exchange Advisor Shares of a Fund for Advisor
Shares of other Warburg Pincus Funds.

                  The exchange privilege is available to shareholders residing
in any state in which the Fund's shares being acquired may legally be sold.
When an investor effects an exchange of shares, the exchange is treated for
federal income tax purposes as a redemption.  Therefore, the investor may
realize a taxable gain or loss in connection with the exchange.  No initial
sales charge is imposed on the shares being acquired in an exchange.  See "How
to Redeem and Exchange Shares" in the accompanying Prospectuses of the New
Warburg Funds.

                  DIVIDENDS.  Each New Warburg Fund and each Existing Warburg
Fund will distribute substantially all of the net investment income and net
realized capital gains, if any, of the Fund to the Fund's shareholders.  All
distributions are reinvested in the form of additional full and fractional
shares unless a shareholder elects otherwise.  The Existing and New Growth &
Income and Balanced Funds declare and pay dividends, if any, from net
investment income quarterly.  The Existing and New Tax Free Funds declare
dividends from net investment income daily and pay such dividends monthly.
Net realized capital gains (including net short-term capital gains), if any,
of each New Warburg Fund, like each Existing Warburg Fund, will be distributed
at least annually.  See "Dividends, Distributions and Taxes" in the
accompanying Prospectuses of the New Warburg Funds.

                  SHAREHOLDER VOTING RIGHTS.  The New Warburg Funds are
registered with the Securities and Exchange Commission as open-end management
investment companies.  The Existing Warburg Funds are each a separate series
of RBB Fund which is also registered as an open-end management investment
company.  The RBB Fund and the New Warburg Funds are Maryland corporations,
each having a Board of Directors.  Shareholders of both the New Warburg Funds
and the Existing Warburg Funds have similar voting rights.  Neither the New
Warburg Fund nor the RBB Fund on behalf of the Existing Warburg Funds holds a
meeting of shareholders annually, except as required by the 1940 Act or other
applicable law.  Each New Warburg Fund's By-Laws provides that shareholders
collectively owning at least ten percent of the outstanding shares of all
classes of stock of the Fund have the right to call for a meeting of
shareholders to consider the removal of one or more directors.  To the extent
required by law, the New Warburg Funds will assist in shareholder
communication in such matters.


<PAGE>10


                  In addition, under the laws of the State of Maryland,
shareholders of the New Warburg Funds and the Existing Warburg Funds do not
have appraisal rights in connection with a combination or acquisition of the
assets of the Fund by another entity.  Shareholders of an Existing Warburg
Fund may, however, redeem their shares at net asset value prior to the date of
the Reorganization.  See "Information on Shareholders' Rights -- Voting
Rights."


                                  RISK FACTORS
   
                  Due to the fact that the investment objectives and policies
of each New Warburg Fund are virtually identical to those of the corresponding
Existing Warburg Fund, the investment risks are substantially similar.  See
the accompanying Prospectuses of the applicable New Warburg Fund for a
complete discussion of the risks of investing in that Fund.
    

                         REASONS FOR THE REORGANIZATIONS

                  The Board of Directors of the RBB Fund has determined that
it is in the best interest of each Existing Warburg Fund to effect the
Reorganization.  In reaching this conclusion, the Board considered a number of
factors, including the following:

                  1.       the terms and conditions of the Reorganizations;

                  2.       the identical investment objectives and
         substantially identical  policies and restrictions of each
         New Warburg Fund in relation to those of the corresponding Existing
         Warburg Fund;

                  3.       that the investment advisor, co-administrators,
         custodian, transfer agent and accountant for each New Warburg Fund
         are the same as those of the corresponding Existing Warburg Fund;

                  4. the federal tax consequences of the  Reorganizations to
         the Existing  Warburg Funds,  the New Warburg Funds and the
         shareholders of each,  and that a legal opinion will be rendered that
         no recognition of income,  gain or loss for federal  income tax
         purposes  will occur as a result of the Reorganizations to any of
         them;

                  5.       that the interests of shareholders of the Existing
         Warburg Funds will not be diluted as a result of the Reorganizations;
   
                  6.       that CSI and PFPC Inc., the Fund's co-administrator
         ("PFPC"), (or  their affiliates)  have agreed to waive fees and
         reimburse expenses for the one-year  period  following the closing of
         the Reorganizations  to the extent  necessary for the net


<PAGE>11

         expense ratio of each New Warburg Fund to be no higher than that of
         the  corresponding  Existing  Warburg Fund on May 3, 1996, or such
         date as may be agreed upon by the parties to the Reorganizations (the
         "Closing Date");
    
                  7.       that the expenses of the Reorganizations will be
         borne by Warburg;

                  8.       that no sales charge will be imposed in connection
         with the Reorganizations;

                  9.       that the Reorganizations would integrate the
         Existing Warburg Funds fully into the Warburg Pincus Funds family,
         thereby, among other things, reducing confusion in the marketplace
         and reducing the possibility of inconsistencies in operations;

                  10.      that the Reorganizations may increase economic
         efficiencies of the Existing Warburg Funds; and

                  11.      that the Reorganizations would remove certain
         regulatory limitations on the ability of the Existing Warburg Funds
         to effect certain transactions with parties that are affiliated
         persons of the RBB Fund.

                  In light of the foregoing, the Board of Directors of the RBB
Fund, including the Independent Directors, has determined that it is in the
best interest of each Existing Warburg Fund and its shareholders to effect the
Reorganization.  The Board of Directors has also determined that the
Reorganization of an Existing Warburg Fund and the corresponding New Warburg
Fund would not result in a dilution of the interests of the Existing Warburg
Fund's shareholders.

                  The Board of Directors of each New Warburg Fund has also
determined that it is advantageous to the New Warburg Fund to effect the
Reorganization.  The Board of Directors also considered the terms and
conditions of the Reorganization and representations that the Reorganization
would be effected as a tax-free reorganization.  Accordingly, the Board of
Directors of each New Warburg Fund, including a majority of the Independent
Directors, has determined that the Reorganization is in the best interests of
the New Warburg Fund's shareholders and that the interests of the New Warburg
Fund's shareholders would not be diluted as a result of the Reorganization.

*    CSI and PFPC  Inc.  (or their  affiliates)  have  agreed to waive  fees and
     reimburse expenses of each New Warburg Fund for a one-year period following
     the  closing  of a  Reorganization  so that the  expense  ratio of each New
     Warburg  Fund will be no higher  than  that of the  corresponding  Existing
     Warburg Fund on or before the Closing Date of the Reorganization.
   
**   The Advisor Shares impose a 12b-1 fee of up to .75% per annum, which is the
     economic  equivalent  of a  sales  charge.  Long-term  shareholders  of the
     Balanced  Fund,  the Tax Free Fund or Advisor  Shares may pay more than the
     economic equivalent of the maximum front-end sales charges permitted by the
     National Association of Securities Dealers, Inc. (the "NASD").


     Expenses  for the Funds reflect current expense levels as of March 1,
1996.  In addition, the Fee Tables reflect a voluntary waiver of Management
Fees and the reimbursement of a portion of the expenses of the
Existing Balanced and Tax Free Funds by Warburg.  Absent such  waivers
and expense reimbursements, Management Fees for the Existing Balanced  Fund
and Existing Tax Free Fund would have equaled .90% and .50%, respectively;
Other Expenses for the Common Shares  of the Existing Balanced and Tax
Free Funds would have equaled 1.71% and 2.86%, respectively, and, with respect
to the Existing Balanced Fund Advisor Shares, Other Expenses would have
equaled 1.71%;  and Total Fund Operating Expenses for the Common Shares
of the Existing Balanced and Tax Free Funds would have equaled 2.86% and
3.61%, respectively, and with respect to Existing Balanced Fund Advisor
Shares, would have equaled 3.11%.

varying  investment  periods.  To facilitate  such  comparison,  all funds are
required to utilize a 5.00% annual return  assumption.  However,  each  Fund's
actual  return will vary and may be greater  or  less  than  5.00%.   These
examples   should  not  be  considered representations of past or future
expenses and actual expenses may be greater or lesser than those shown.

                      INFORMATION ABOUT THE REORGANIZATIONS
   
                  AGREEMENT AND PLAN OF REORGANIZATION. The following summary of
each Plan is qualified in its entirety by reference to the form of Plan (Exhibit
A hereto).  Each Plan  provides  that the relevant New Warburg Fund will acquire
all or  substantially  all of the assets of the  corresponding  Existing Warburg
Fund in exchange  for shares of the New Warburg Fund and the  assumption  by the
New Warburg Fund of the liabilities of the Existing  Warburg Fund on the Closing
Date.

                  Prior to the  Closing  Date,  the RBB Fund on  behalf  of
each Existing  Warburg Fund will endeavor to discharge  all of its known
liabilities and obligations.  The New Warburg Fund shall assume all
liabilities,  expenses, costs,  charges and reserves  reflected on an
unaudited  statement of assets and liabilities of the  corresponding  Existing
Warburg Fund prepared by PFPC as of the close of regular  trading on the New
York Stock  Exchange,  Inc.,  currently 4:00 p.m. New York City time, on the
Closing Date, in accordance  with generally accepted  accounting  principles
consistently  applied  from the prior  audited period.  The  New  Warburg
Fund  shall  also  assume  any  liabilities  of  the corresponding   Existing
Warburg  Fund  arising  from  the  operations   and/or transactions  of the
Existing  Warburg Fund prior to and  including  the Closing Date.  The net
asset  value  per  share  of each  class  of each  Fund  will be determined by
adding the relevant class' pro rata share of the Fund's securities, cash and
other  assets,  deducting  the  relevant  class'  pro rata share of the actual
and accrued  liabilities  and the liabilities specifically  allocated to that
class of shares, and dividing the result by the total number of outstanding
shares of the relevant class.  Each Existing Warburg Fund and the
corresponding New Warburg  Fund will  utilize  the procedures  set forth in
their  respective current  Prospectuses  or Statements of Additional
Information to determine the value of their respective  portfolio  securities
and to determine the aggregate value of each Fund's portfolio.
    

                  At or prior to the  Closing  Date,  the RBB Fund on behalf
of each Existing Warburg Fund will declare a dividend or dividends which,
together with all previous such  dividends,  will have the effect of
distributing to the Existing  Warburg  Fund's  shareholders all of the  Fund's
investment company taxable  income for all taxable  years ending on or prior
to the Closing  Date (computed without regard to any deduction for dividends
paid).  In addition, each Existing  Warburg Fund's dividend will include its
net capital gains realized in all taxable years ending on or prior to the
Closing Date (after reductions  for any capital loss carryforward).

                  As soon after the Closing  Date as  conveniently  practicable,
each  Existing   Warburg  Fund  will   liquidate  and  distribute  pro  rata  to
shareholders  of record  as of the close of  business  on the  Closing  Date the
shares of the same class of the  corresponding  New Warburg Fund received by the
Existing Warburg Fund. Such liquidation and distribution will be accomplished by
the  establishment  of  accounts  in the names of the  Existing  Warburg  Fund's
shareholders  on the share  records  of the  corresponding  New  Warburg  Fund's
transfer  agent.  Each account will  represent the respective pro rata number of
shares of the class of shares of the  corresponding New Warburg Fund due to each
of the Existing Warburg Fund's

<PAGE>18


shareholders.  After such  distribution and the winding up of its affairs,  each
Existing Warburg Fund will be terminated as a series of the RBB Fund.

                  The  consummation  of each  Reorganization  is  subject to the
conditions set forth in the Plan.  Notwithstanding  approval by the shareholders
of an  Existing  Warburg  Fund,  the Plan may be  terminated  with  respect to a
Reorganization  at any time at or  prior  to the  Closing  Date:  (i) by  mutual
agreement  of the RBB Fund,  on  behalf of an  Existing  Warburg  Fund,  and the
corresponding  New Warburg Fund;  (ii) by the RBB Fund, on behalf of an Existing
Warburg Fund, in the event the  corresponding  New Warburg Fund shall,  or a New
Warburg Fund, in the event the RBB Fund or the  corresponding  Existing  Warburg
Fund  shall,  materially  breach  any  representation,   warranty  or  agreement
contained in the Plan to be performed at or prior to the Closing  Date; or (iii)
if a condition to the Plan  expressed to be precedent to the  obligations of the
terminating party has not been met and it reasonably appears that it will not or
cannot be met.

                  Pursuant  to the Plan,  each New  Warburg  Fund has  agreed to
indemnify  and  advance  expenses  to each  director  or officer of The RBB Fund
against money damages  incurred in connection with any claim arising out of such
person's services as a director or officer with respect to matters  specifically
relating to the corresponding  Existing Warburg Fund. Each Existing Warburg Fund
has obtained a rider for its current  directors  and officers  liability  policy
extending  the period for making  claims  under the  policy  until  three  years
following  the Closing  Date.  The premium  for the  three-year  period has been
prepaid by the Existing Warburg Fund.
   
                  Warburg  has agreed to  indemnify  each person who served as a
director or officer of The RBB Fund on the date of execution  of the Plan
against any and all  direct  and  indirect  liabilities,  losses,  claims,
damages  and expenses (including,  without limitation,  reasonable  attorneys'
fees) (each, a "Loss")  that arise  from or relate to the  operations
commencing  on the first business day after the Closing Date of the New
Warburg Funds, to the extent that a Loss has not been recovered against the
relevant New Warburg Fund.

    

                  Approval  of the Plan with  respect to each Existing
Warburg Fund will require the  affirmative  vote of a majority of each
Existing Warburg Fund's outstanding shares in the aggregate without regard to
class, in person or by proxy, if a quorum is present.  The approval of
shareholders of any other RBB Fund or of shareholders  of the New Warburg
Funds is not required.  Implementing the Reorganization by any one Existing
Warburg Fund would not be conditioned on receipt of shareholder approval by
any other Existing Warburg Fund. Shareholders of the Existing  Warburg  Funds
are entitled to one vote for each share.  If the Reorganization  is not
approved by shareholders of an Existing Warburg Fund, the Board of Directors
of the RBB Fund on behalf of the applicable  Existing Warburg Fund will
consider other possible  courses of action  available to it, including
resubmitting the Reorganization proposal to shareholders.

                  DESCRIPTION OF THE NEW WARBURG FUNDS' SHARES.  Shares of
each New Warburg Fund will be issued to the corresponding Existing Warburg
Fund in

<PAGE>19


accordance with the procedures  detailed in the Plan and as described in the New
Warburg  Fund's  Prospectuses.   The  New  Warburg  Funds  do  not  issue  share
certificates to shareholders.  See "Information on Shareholders' Rights" and the
Prospectuses of the New Warburg Funds for additional information with respect to
the shares of the New Warburg Funds.

                  FEDERAL  INCOME TAX  CONSEQUENCES.  The  exchange of assets of
each Existing Warburg Fund for shares of the  corresponding  New Warburg Fund is
intended to qualify for federal income tax purposes as a tax-free reorganization
under  Section  368(a) of the  Internal  Revenue  Code of 1986,  as amended (the
"Code"). As a condition to the closing of the  Reorganization,  each New Warburg
Fund and the RBB Fund on behalf of the corresponding  Existing Warburg Fund will
receive an opinion from  Willkie  Farr &  Gallagher,  counsel to the New Warburg
Funds, to the effect that, on the basis of the existing  provisions of the Code,
U.S. Treasury  regulations  issued  thereunder,  current  administrative  rules,
pronouncements  and court  decisions,  for  federal  income tax  purposes,  upon
consummation of the Reorganization:

          (1) the transfer of all or substantially  all of each Existing Warburg
         Fund's  assets in exchange  for the  corresponding  New Warburg  Fund's
         shares and the assumption by the New Warburg Fund of liabilities of the
         Existing  Warburg Fund will  constitute a  "reorganization"  within the
         meaning of Section 368(a) of the Code, and the New Warburg Fund and the
         corresponding   Existing   Warburg   Fund  are  each  a  "party   to  a
         reorganization" within the meaning of Section 368(b) of the Code;

          (2) no gain or loss will be  recognized  by each New Warburg Fund upon
         the receipt of the assets of the  corresponding  Existing  Warburg Fund
         solely in exchange for the New Warburg Fund's shares and the assumption
         by the New Warburg Fund of  liabilities of the  corresponding  Existing
         Warburg Fund;

          (3) no gain or loss will be recognized  by each Existing  Warburg Fund
         upon  the  transfer  of  the  Existing  Warburg  Fund's  assets  to the
         corresponding  New Warburg Fund in exchange for the New Warburg  Fund's
         shares and the assumption by the New Warburg Fund of liabilities of the
         Existing  Warburg  Fund or upon the  distribution  (whether  actual  or
         constructive)  of the New Warburg Fund's shares to the Existing Warburg
         Fund's shareholders;

          (4) no  gain  or  loss  will be  recognized  by  shareholders  of each
         Existing  Warburg  Fund upon the exchange of their shares for shares of
         the  corresponding  New  Warburg  Fund  and the  assumption  by the New
         Warburg Fund of liabilities of the Existing Warburg Fund;

          (5) the  aggregate  tax basis of the shares of each New  Warburg  Fund
         received by each shareholder of the corresponding Existing Warburg Fund
         pursuant to the  Reorganization  will be the same as the  aggregate tax
         basis of shares of the Existing  Warburg Fund held by such  shareholder
         immediately  prior to the  Reorganization,  and the  holding  period of
         shares of the New Warburg Fund to be received by each

<PAGE>20


         shareholder of the Existing  Warburg  Fund will include the period
         during which shares of the Existing  Warburg Fund  exchanged
         therefor were held by such  shareholder  (provided  shares of the
         Existing Warburg Fund were held as capital assets on the date of the
         Reorganization); and

          (6) the tax basis of each Existing  Warburg Fund's assets  acquired by
         the corresponding New Warburg Fund will be the same as the tax basis of
         such  assets to the  Existing  Warburg  Fund  immediately  prior to the
         Reorganization,  and the holding  period of the assets of the  Existing
         Warburg  Fund in the hands of the New  Warburg  Fund will  include  the
         period  during  which those  assets were held by the  Existing  Warburg
         Fund.

                  Shareholders  of each  Existing  Warburg  Fund should  consult
their tax advisors regarding the effect, if any, of the proposed  Reorganization
in light of their individual circumstances.  Since the foregoing discussion only
relates  to  the  federal  income  tax   consequences  of  the   Reorganization,
shareholders  of each  Existing  Warburg  Fund  should  also  consult  their tax
advisors as to state and local tax consequences, if any, of the Reorganization.
   
                  CAPITALIZATION.  The following table shows the  capitalization
of each Fund as of the close of business on February  29, 1996 and the  combined
pro forma  capitalization as if each Reorganization had occurred as of the close
of business on that date.

                  The New  Warburg  Funds  will not  commence  operations  until
consummation of the Reorganizations and, accordingly,  as of March 1, 1996 there
were no outstanding shares of the New Warburg Funds.

                  As of the Record Date,  the officers and  Directors of the RBB
Fund  beneficially  owned as a group less than 1% of the  outstanding  shares of
each Existing  Warburg  Fund.  To the best  knowledge of the RBB Fund, as of the
Record Date, no shareholder or "group" (as that term is used in Section 13(d) of
the Securities  Exchange Act of 1934 (the "Exchange Act")),  except as set forth
in the  table  below,  owned  beneficially  or of  record  more  than  5% of the
outstanding shares of a class of an Existing Warburg Fund.

              COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES

                  The  following  discussion  is based upon and qualified in its
entirety by the  disclosures  in the  Prospectuses  and Statements of Additional
Information of the New Warburg Funds and the Existing Warburg Funds.

                  INVESTMENT OBJECTIVES.  As stated above each Existing
Warburg Fund and its corresponding New Warburg Fund have the same investment
objective.  There can be no assurance that any Fund will achieve its
investment objective.  The investment objectives of

<PAGE>23


the New Warburg Funds,  like those of the Existing Warburg Funds, may be changed
by the Board of  Directors  without  the  affirmative  vote of the  holders of a
majority of the outstanding  shares of the relevant Fund (as defined in the 1940
Act).

                  PRIMARY INVESTMENTS.  The New Warburg Funds were organized for
the purpose of acquiring the assets of the corresponding  Existing Warburg Funds
and have the same portfolio managers.  In addition,  the investment policies and
investment  restrictions  of the New Warburg  Funds were  developed so that they
would be identical to those of the corresponding  Existing Warburg Funds, except
as follows:

                   (1) the  borrowing  limit of the New Growth & Income  Fund is
30% of total assets, while that of the Existing Growth & Income Fund is 10%; and

                   (2) the New Growth & Income Fund may pledge up to 125% of any
amount it borrows  while the Existing  Growth & Income Fund may pledge up to the
lesser of the amount borrowed or 10% of its assets at the time of borrowing.

                  All of the  investment  restrictions  of the Existing  Warburg
Funds are  fundamental and cannot be changed without the approval of the holders
of a majority of a Fund's outstanding  shares.  While the New Warburg Funds have
the same investment  restrictions  (except as previously stated),  the following
restrictions have been reclassified as  non-fundamental  and can be changed by a
New Warburg  Fund's Board of Directors  without  shareholder  approval:  (i) the
prohibition  of a Fund  investing  in oil,  gas or  mineral-related  programs or
leases;  (ii) the  prohibition of a Fund  investing in securities  issued by any
other investment company; and (iii) the prohibition of a Fund making investments
for  purposes  of  exercising  control  or  management.  Warburg  has no current
intention of recommending any change to any non-fundamental investment policy of
the New Warburg Funds for the first year of their operations.

                             MANAGEMENT OF THE FUND

                  Warburg will provide investment  advisory services to each New
Warburg Fund under an advisory agreement substantially identical to the advisory
agreement  currently in effect between Warburg and the RBB Fund relating to each
Existing  Warburg  Fund.  The same  persons  who today are  responsible  for the
day-to-day  management of each Existing  Warburg Fund will continue in that role
after the Reorganizations. In addition, PFPC Inc. and Counsellors Funds Services
Inc. would continue to provide  accounting and  co-administrative  services,  as
applicable,  and CSI would continue to provide distribution services, each under
new agreements  substantially identical to those now in effect for each Existing
Warburg Fund.  In  particular,  the advisory  fees,  co-administration  fees and
distribution fees payable under the related agreements would not be changed as a
result of the Reorganization.

                  State Street Bank and Trust  Company will continue its role as
shareholder  servicing agent, transfer agent and dividend disbursing agent after
the  Reorganizations.  PNC Bank will  continue to serve as  custodian  and State
Street Bank as co-custodian for foreign

<PAGE>24


securities.  The fees payable for transfer agency and custodial services will be
no higher after the Reorganizations  than before.  Coopers & Lybrand L.L.P., the
auditors for the Existing  Warburg  Funds,  will also serve in that capacity for
the New Warburg Funds.

                 INTEREST OF WARBURG IN THE REORGANIZATIONS
   
                  Warburg  may be deemed to have an interest in the Plan and the
Reorganizations because it provides investment advisory services to the Existing
Warburg Funds. Warburg receives compensation from the Existing Warburg Funds for
services it provides pursuant to advisory  agreements.  The terms and provisions
of these  arrangements are described in the New Warburg Fund Prospectuses  under
"Management of the Fund -- Investment  Adviser."  Future growth of assets of the
New Warburg Funds,  if any, can be expected to increase the total amount of fees
payable  to  Warburg  and its  affiliates  and to reduce  the amount of fees and
expenses  required to be waived to maintain  total fees and  expenses of the New
Warburg  Funds at  agreed  upon  levels.  Warburg  may also be deemed to have an
interest in the Plan and the Reorganizations  because, as of the Record Date, it
or one or more of its affiliates  possessed or shared voting power or investment
power as a fiduciary on behalf of its customers in the Existing  Growth & Income
Fund[,  and owned all of each  outstanding  shares  of each New  Warburg  Fund].
Warburg and its  affiliates  have  advised the  Existing  Warburg  Funds that it
intends to vote the shares over which it has voting  power at the Meeting (i) in
the manner instructed by the customers for which such shares are held or (ii) in
the event that such  instructions  are not received,  in the same  proportion as
votes cast by other shareholders. See "Voting Information."
    
                  INFORMATION ON SHAREHOLDERS' RIGHTS
   
                  GENERAL.  The RBB Fund and the New Warburg  Funds are open-end
diversified management investment companies registered under the 1940 Act, which
continuously  offer to sell  shares  at their  current  net asset  values.  Each
Existing  Warburg  Fund  is a  series  of the  RBB  Fund,  which  is a  Maryland
corporation  that was  incorporated  on February 29, 1988 and is governed by its
Articles of Incorporation, By-Laws and Board of Directors. Each New Warburg Fund
is a Maryland  corporation  organized on January 24, 1996 and is governed by its
Articles of  Incorporation,  By-Laws and Board of  Directors.  Each Fund is also
governed by  applicable  state and federal law.  The RBB Fund has an  authorized
capital of thirty  billion  shares of common stock with a par value of $.001 per
share.  Each New Warburg Fund has an authorized  capital of three billion shares
of common  stock with a par value of $.001 per share.  The Board of Directors of
the RBB Fund has  authorized  the issuance of seventeen  series of shares,  each
representing shares in one of seventeen separate  portfolios,  and may authorize
the issuance of  additional  series of shares in the future.  The assets of each
portfolio are segregated and separately managed and a shareholder's  interest is
in the  assets of the  portfolio  in which he or she holds  shares.  In each New
Warburg Fund and each Existing Warburg Fund,  shares represent  interests in the
assets of the relevant Fund and have identical voting, dividend, liquidation and
other rights on the same terms and  conditions  except that expenses  related to
the distribution of each class of shares of a Fund are borne
    
<PAGE>25


solely by such class and each class of shares has  exclusive  voting rights with
respect to provisions of such Fund's Rule 12b-1  distribution plan pertaining to
a particular class.

                  MULTI-CLASS  STRUCTURE.  The New and  Existing  Tax Free Funds
have issued only one class of shares. The New and Existing Growth & Income Funds
and the Balanced Funds each have issued two classes of shares: Common Shares and
Advisor Shares.  Individual  investors may purchase  Advisor Shares only through
institutional  shareholders of record,  broker-dealers,  financial institutions,
depository institutions and other financial intermediaries ("Institutions").

                  The New and Existing  Growth & Income and  Balanced  Funds are
authorized to offer Advisor Shares  exclusively to Institutions whose clients or
customers (or participants in the case of retirement  plans)  ("Customers")  are
beneficial  owners of Advisor  Shares.  Either those  Institutions  or companies
providing  certain  services to them (together,  "Service  Organizations")  will
enter into service agreements  ("Agreements") related to the sale of the Advisor
Shares with CSI  pursuant to a  Distribution  Plan.  Pursuant to the terms of an
Agreement,  the Service  Organization  agrees to perform  certain  distribution,
shareholder  servicing,   administrative  and/or  accounting  services  for  its
Customers.  Distribution  services  would  be  marketing  or other  services  in
connection with the promotion and sale of Advisor Shares.  Shareholder  services
that  may be  provided  include  responding  to  Customer  inquiries,  providing
information on Customer  investments  and providing  other  shareholder  liaison
services.  See  "Shareholder  Servicing" in the Prospectuses of the Existing New
Warburg Funds for Advisor Shares.

                  DIRECTORS. The By-Laws of the RBB Fund and of each New Warburg
Fund provide that the term of office of each Director  shall be from the time of
his or her election and qualification until his or her successor shall have been
elected  and  shall  have  qualified.  Any  Director  of the RBB Fund or any New
Warburg  Fund may be removed by the vote of at least a majority of the shares of
capital stock then entitled to be cast for the election of Directors.  Vacancies
on the  Boards  of the RBB Fund or any New  Warburg  Fund may be  filled  by the
Directors  remaining in office.  A meeting of shareholders  will be required for
the purpose of electing  additional  Directors whenever fewer than a majority of
the Directors then in office were elected by shareholders.

                  VOTING  RIGHTS.  Neither the RBB Fund nor any New Warburg Fund
holds a meeting of  shareholders  annually,  and there normally is no meeting of
shareholders for the purpose of electing Directors unless and until such time as
less than a  majority  of the  Directors  holding  office  have been  elected by
shareholders.
   
                  LIQUIDATION OR TERMINATION. In the event of the liquidation or
termination of any of the investment funds of the RBB Fund or of any New Warburg
Fund, the shareholders of the fund are entitled to receive, when and as declared
by the Directors, the excess of the assets over the liabilities belonging to the
fund.  In  either  case,  the  assets so  distributed  to  shareholders  will be
distributed among the shareholders in proportion to the number of shares of each
class held by them and recorded on the books of the fund.


<PAGE>26



                  LIABILITY OF DIRECTORS.  The Articles of  Incorporation of the
RBB Fund and of each New Warburg Fund provide  that the  Directors  and officers
shall not be liable  for  monetary  damages  for breach of  fiduciary  duty as a
Director or officer,  except to the extent such  exemption  is not  permitted by
law. The Articles of  Incorporation  further  provide that the RBB Fund and each
New Warburg Fund shall indemnify each Director and officer and provide  advances
for the payment of expenses relating to the matter for which  indemnification is
sought, each to the fullest extent permitted by Maryland General Corporation Law
and other  applicable  law.  Pursuant to the Plan, each New Warburg Fund extends
this same  protection  to current  directors  and  officers  of the RBB Fund for
liability relating to the corresponding Existing Warburg Fund.
    
                  RIGHTS OF INSPECTION.  Maryland law permits any shareholder of
the RBB Fund and of each New Warburg  Fund or any agent of such  shareholder  to
inspect  and  copy,  during  usual  business  hours,  the  By-Laws,  minutes  of
shareholder  proceedings,  annual  statements  of the affairs  and voting  trust
agreements  of the RBB Fund and the New  Warburg  Fund on file at its  principal
offices.

                  SHAREHOLDER LIABILITY. Under Maryland law, shareholders of the
RBB  Fund and of each  New  Warburg  Fund do not  have  personal  liability  for
corporate  acts and  obligations.  Shares of a New  Warburg  Fund  issued to the
shareholders of the  corresponding  Existing Warburg Fund in the  Reorganization
will  be  fully  paid  and  nonassessable  when  issued,   transferable  without
restrictions and will have no preemptive rights.

                  The foregoing is only a summary of certain  characteristics of
the  operations  of the New  Warburg  Funds  and the RBB Fund on  behalf  of the
Existing  Warburg  Funds.  The  foregoing is not a complete  description  of the
documents  cited.  Shareholders  should refer to the provisions of the corporate
documents and state laws governing each Fund for a more thorough description.


                          ADDITIONAL INFORMATION


                  Both the RBB Fund and the New Warburg Funds are subject to the
informational  requirements  of  the  Exchange  Act  and  the  1940  Act  and in
accordance  therewith  file  reports  and  other  information   including  proxy
material,  reports and charter  documents,  with the SEC. These materials can be
inspected and copies obtained at the Public Reference  Facilities  maintained by

York  10048.  Copies  of such  material  can also be  obtained  from the  Public
Reference  Branch,  Office of Consumer  Affairs and Information  Services,  SEC,
Washington, D.C. 20549 at prescribed rates.

                              VOTING INFORMATION
   
                  This  Combined  Prospectus/Proxy  Statement  is  furnished  in
connection  with a solicitation  of proxies by the Board of Directors of the RBB
Fund to be used at the Special Meeting of  Shareholders of the Existing  Warburg
Funds to be held at 3:00 p.m.  on May 1, 1996,  at the  offices of The RBB Fund,
Inc., 400 Bellevue Parkway,  Wilmington,  Delaware, 19809 and at any adjournment
or adjournments thereof. This Combined Prospectus/Proxy  Statement, along with a
Notice of the Meeting and proxy card(s),  is first being mailed to  shareholders
of the Existing  Warburg Funds on or about March 8, 1996.  Only  shareholders of
record as of the close of business on the Record Date will be entitled to notice
of, and to vote at, the  Meeting or any  adjournment  thereof.  As of the Record
Date,  the Existing  Warburg  Funds had the  following  shares  outstanding  and
entitled to vote: Existing Growth & Income Fund 63,992,111.6950 (Common Shares),
4,939,664.0300  (Advisor Shares);  Existing Balanced Fund 1,655,020.2620 (Common
Shares),  111.0930  (Advisor  Shares);  and Existing Tax Free Fund  416,881.9450
(Common  Shares).  The holders of one-third of the shares of an Existing Warburg
Fund  outstanding  at the close of business on the Record Date present in person
or represented  by proxy will  constitute a quorum for the Meeting of that Fund.
For purposes of  determining a quorum for  transacting  business at the Meeting,
abstentions  and broker  "non-votes"  (that is, proxies from brokers or nominees
indicating that such persons have not received  instructions from the beneficial
owner or other  persons  entitled  to vote  shares on a  particular  matter with
respect to which the brokers or nominees do not have  discretionary  power) will
be treated as shares that are  present  but which have not been voted.  For this
reason, abstentions and broker non-votes will have the effect of a "no" vote for
purposes of obtaining the requisite  approval of the Plan. If the enclosed proxy
is  properly  executed  and  returned  in time to be voted at the  Meeting,  the
proxies  named  therein  will  vote  the  shares  represented  by the  proxy  in
accordance with the instructions marked thereon.  Unmarked proxies will be voted
FOR approval of the relevant Plan and FOR approval of any other  matters  deemed
appropriate.  A proxy may be  revoked  at any time on or before  the  Meeting by
written notice to the Secretary of The RBB Fund,  Inc.,  Bellevue Park Corporate
Center, 400 Bellevue Parkway, Suite 100, Wilmington, Delaware 19809.
    
                  Approval  of the Plan with  respect to each  Existing  Warburg
Fund will require the  affirmative  vote of a majority of each Existing  Warburg
Fund's outstanding  shares,  voting in the aggregate without regard to class, in
person or by proxy, if a quorum is present.  The approval of shareholders of any
other  investment  series  of the RBB  Fund is not  required.  Implementing  the
Reorganization  by any one  Existing  Warburg Fund would not be  conditioned  on
receipt of shareholder approval by any other Existing Warburg Fund. Shareholders
of the Existing Warburg Funds are entitled to one vote for each share.
   
                  Proxy solicitations will be made primarily by mail, but
proxy solicitations also may be made by telephone, telegraph or personal
interviews conducted by officers and employees of Warburg and/or by PFPC or
their respective affiliates.  In addition, D.F. King & Co. Inc. ("D.F. King"),
or an agent of D.F. King may call shareholders to ask if they would be willing
to authorize D.F. King or its agent to execute a proxy on their behalf

<PAGE>28


authorizing the voting of their shares in accordance with the instructions given
over the  telephone  by the  shareholders.  The  latter  telephone  solicitation
procedure is designed to authenticate the shareholder's identity by, among other
things,  asking the shareholder to provide his or her social security number (in
the case of an individual) or taxpayer  identification number (in the case of an
entity). The shareholder's  instructions will be implemented in a proxy executed
by D.F. King or its agent and a confirmation  will be sent to the shareholder to
ensure that the vote has been  authorized in accordance  with the  shareholder's
instructions.  Although a  shareholder's  vote may be solicited and cast in this
manner,  each shareholder will receive a copy of this Combined  Prospectus/Proxy
Statement  and may vote by mail or by fax using the  enclosed  proxy  card.  The
Existing  Warburg  Funds believe that this  telephone  voting system will comply
with  Maryland law and will obtain an opinion of counsel to that effect prior to
implementing  such  procedures.  The  aggregate  cost  of  solicitation  of  the
shareholders  of the  Existing  Warburg  Fund is  expected  to be  approximately
$54,000 to $78,000.  All expenses of the Reorganization,  including the costs of
the  proxy  solicitation  and the  preparation  of  enclosures  to the  Combined
Prospectus/Proxy Statement, reimbursement of expenses of forwarding solicitation
material  to  beneficial  owners  of shares of the  Existing  Warburg  Funds and
expenses   incurred  in  connection   with  the  preparation  of  this  Combined
Prospectus/Proxy Statement will be borne by Warburg or its affiliates (excluding
extraordinary  expenses not normally associated with transactions of this type).
It is anticipated that banks, brokerage houses and other institutions,  nominees
and  fiduciaries  will be requested  to forward  proxy  materials to  beneficial
owners and to obtain authorization for the execution of proxies.  Warburg or its
affiliates,  may,  upon request,  reimburse  banks,  brokerage  houses and other
institutions,  nominees and fiduciaries  for their expenses in forwarding  proxy
materials to beneficial owners.

                  In the  event  that a  quorum  necessary  for a  shareholders'
meeting is not present or sufficient votes to approve the  Reorganization  of an
Existing  Warburg  Fund are not  received by May 1, 1996,  the persons  named as
proxies may propose one or more  adjournments  of the Meeting to permit  further
solicitation  of proxies.  In  determining  whether to adjourn the Meeting,  the
following factors may be considered:  the percentage of votes actually cast, the
percentage  of  negative   votes  actually  cast,  the  nature  of  any  further
solicitation and the information to be provided to shareholders  with respect to
the  reasons  for  the  solicitation.  Any  such  adjournment  will  require  an
affirmative  vote by the  holders  of a majority  of the shares of the  relevant
Existing  Warburg Fund present in person or by proxy and entitled to vote at the
Meeting.  The persons  named as proxies will vote upon a decision to adjourn the
Meeting with respect to an Existing Warburg Fund after consideration of the best
interests of all shareholders of that Fund.

                  As of the Record Date,  Warburg (or its affiliates)  possessed
or shared  voting  power or  investment  power as a  fiduciary  on behalf of its
customers,  with respect to the  following  number of shares  (constituting  the
percentage  of  outstanding  shares  indicated  in  parentheses)  of each of the
respective  Existing  Warburg  Funds:  Existing  Warburg  Growth & Income  Fund,
6,519,945.608 (10.19%);  Existing Warburg Balanced Fund, 19,351.726 (1.17%); and
Existing Warburg Tax Free Fund, 34,729.816 (8.33%).
    


<PAGE>29


                            OTHER BUSINESS

                  The RBB Fund Board of Directors  knows of no other business to
be brought  before the Meeting.  However,  if any other  matters come before the
Meeting,  proxies that do not contain specific restrictions to the contrary will
be voted on such matters in accordance with the judgment of the persons named in
the enclosed Proxy Card.

                  The approval of  shareholders  of the New Warburg Funds is not
required in order to affect the Reorganizations and,  accordingly,  the votes of
the  shareholders  of the New  Warburg  Funds  are not being  solicited  by this
Combined Prospectus/Proxy Statement.

                     FINANCIAL STATEMENTS AND EXPERTS

                  The  audited  statement  of  assets  and  liabilities  of each
Existing Warburg Fund,  including the schedule of portfolio  investments,  as of
August 31, 1995,  the related  statements of operations for the year then ended,
the  statement  of changes in net assets for each of the two years in the period
then ended and the financial  highlights  for each of the years in the five-year
period  then ended,  have been  incorporated  by  reference  into this  Combined
Prospectus/Proxy  Statement  in  reliance  upon the reports of Coopers & Lybrand
L.L.P., independent accountants,  given on the authority of such firm as experts
in accounting and auditing.  There is no financial information available at this
time for the New Warburg Funds, which have not yet commenced operations.


                                LEGAL MATTERS
   
                  Certain legal matters concerning the issuance of shares of the
New Warburg Funds will be passed upon by Willkie Farr & Gallagher,  One Citicorp
Center,  153 East 53rd  Street,  New York,  New York  10022,  counsel to the New
Warburg Funds.  In rendering such opinion,  Willkie Farr & Gallagher may rely on
an opinion of  Venable,  Baetjer  and Howard,  LLP as to certain  matters  under
Maryland law.

                                     FORM OF
                      AGREEMENT AND PLAN OF REORGANIZATION

   
         THIS AGREEMENT AND PLAN OF REORGANIZATION  (the "Agreement") is made as
of this 6th day of March, 1996, between and among Warburg,  Pincus ___________
Fund, Inc., a Maryland  corporation  (the  "New  Warburg  Fund"),  and The RBB
Fund, Inc.,  a Maryland corporation (the "RBB Fund"), on behalf of the Warburg
Pincus______________ Fund,  a series of  shares  of the RBB Fund  (the
"Existing Warburg Fund").

    

         This  Agreement  is  intended  to  be  and  is  adopted  as a
plan  of reorganization  and  liquidation  within the  meaning of
Section  368 (a) of the United  States  Internal  Revenue  Code of 1986,  as
amended (the  "Code").  The reorganization of the Existing Warburg Fund
(collectively, the "Reorganization") will consist of the transfer of
substantially  all of the assets of the Existing Warburg  Fund in exchange
solely for shares of the  applicable  class of common stock  (collectively,
the  "Shares"),  of the New  Warburg  Fund  corresponding thereto,  as
indicated  in the table set forth in  Schedule  A hereto,  and the assumption
by the New Warburg Fund of liabilities  of the Existing  Warburg Fund and the
distribution,  after the Closing Date  hereinafter  referred to, of New
Warburg  Fund  Shares  to the  shareholders  of the  Existing  Warburg  Fund  in
liquidation of the Existing Warburg Fund as provided herein,  all upon the terms
and conditions hereinafter set forth in this Agreement.

         WHEREAS,  the  Board  of  Directors  of the RBB Fund on  behalf  of the
Existing  Warburg Fund has determined that the exchange of all of the assets and
the liabilities of the Existing Warburg Fund for New Warburg Fund Shares and the
assumption of such  liabilities by the New Warburg Fund is in the best interests
of the RBB Fund and the  Existing  Warburg  Fund and that the  interests  of the
existing shareholders of the RBB Fund and the Existing Warburg Fund would not be
diluted as a result of this transaction; and

         WHEREAS,  the Board of Directors of the New Warburg Fund has determined
that the  exchange  of all of the assets of the  Existing  Warburg  Fund for New
Warburg  Fund  Shares  is in the  best  interests  of  the  New  Warburg  Fund's
shareholders  and that the  interests  of the existing  shareholders  of the New
Warburg Fund would not be diluted as a result of this transaction.

         NOW,  THEREFORE,  in consideration of the premises and of the covenants
and agreements  hereinafter set forth,  the parties hereto covenant and agree as
follows:



<PAGE>2


1.       TRANSFER OF ASSETS OF THE EXISTING WARBURG FUND IN EXCHANGE FOR NEW
         WARBURG FUND SHARES AND ASSUMPTION OF THE EXISTING WARBURG FUND'S
         LIABILITIES AND LIQUIDATION OF THE EXISTING WARBURG FUND

         1.1.  Subject to the terms and  conditions  herein set forth and on the
basis of the  representations  and  warranties  contained  herein,  the RBB Fund
agrees to transfer the Existing  Warburg Fund's assets as set forth in paragraph
1.2 to the New Warburg Fund  identified  in Schedule A, and the New Warburg Fund
agrees in  exchange  therefor:  (i) to deliver to the RBB Fund the number of New
Warburg Fund Shares, including fractional New Warburg Fund Shares, determined by
dividing the value of the Existing  Warburg  Fund's net assets  attributable  to
each  class of  shares,  computed  in the manner and as of the time and date set
forth in paragraph  2.1, by the net asset value of one New Warburg Fund Share of
the same class,  computed in the manner and as of the time and date set forth in
paragraph 2.2; and (ii) to assume the liabilities of the Existing  Warburg Fund,
as set forth in paragraph 1.3. Such transactions shall take place at the closing
provided for in paragraph 3.1 (the "Closing").

         1.2. (a) The assets of the Existing  Warburg Fund to be acquired by the
New Warburg Fund shall consist of all property  including,  without  limitation,
all cash, securities and dividend or interest receivables which are owned by the
Existing  Warburg Fund and any deferred or prepaid expenses shown as an asset on
the books of the Existing Warburg Fund on the closing date provided in paragraph
3.1 (the "Closing Date").

                  (b) The RBB Fund, on behalf of the Existing  Warburg Fund, has
provided the New Warburg Fund with a list of all of the Existing  Warburg Fund's
assets as of the date of execution of this Agreement. The RBB Fund, on behalf of
the Existing  Warburg Fund,  reserves the right to sell any of these  securities
but will not,  without the prior  approval of the New Warburg Fund,  acquire any
additional securities other than securities of the type in which the New Warburg
Fund is permitted  to invest.  The RBB Fund,  on behalf of the Existing  Warburg
Fund, will, within a reasonable time prior to the Closing Date,  furnish the New
Warburg  Fund with a list of the  securities,  if any, on the  Existing  Warburg
Fund's list  referred to in the first  sentence of this  paragraph  which do not
conform  to  the  New  Warburg  Fund's  investment   objectives,   policies  and
restrictions.  In the event that the Existing Warburg Fund holds any investments
which the New Warburg Fund may not hold, the Existing  Warburg Fund will dispose
of such securities  prior to the Closing Date. In addition,  if it is determined
that the portfolios of the Existing  Warburg Fund and the New Warburg Fund, when
aggregated,  would contain investments exceeding certain percentage  limitations
imposed upon the New Warburg Fund with respect to such investments, the Existing
Warburg  Fund,  if  requested  by the New Warburg  Fund,  will dispose of and/or
reinvest a sufficient amount of such investments as may

<PAGE>3


be necessary to avoid violating such limitations as of the Closing Date.

   

         1.3.  The RBB Fund,  on  behalf  of the  Existing Warburg  Fund,
will endeavor to discharge  all the Existing  Warburg Funds' known
liabilities  and obligations  prior  to the  Closing  Date, other  than  those
liabilities  and obligations  which would otherwise be discharged at a later
date in the ordinary course of business. The New Warburg Fund shall assume all
liabilities, expenses, costs,  charges  and  reserves, including  those
liabilities  reflected  on an unaudited  statement  of assets and  liabilities
of the  Existing  Warburg Fund prepared by PFPC Inc., as of the Valuation
Date (as defined in paragraph  2.1), in accordance with generally accepted
accounting principles consistently applied from the prior audited  period.
The New  Warburg  Fund shall  also  assume any liabilities, expenses, costs or
charges incurred by or on behalf of the Existing Warburg Fund  specifically
arising from or relating to the  operations  and/or transactions  of the
Existing  Warburg Fund prior to and  including  the Closing Date but which are
not reflected on the above-mentioned  statement of assets and liabilities,
including any liabilities, expenses, costs or charges arising under paragraph
5.10 hereof.

    

         1.4. As provided in paragraph 3.4, as soon after the  Closing Date as
is conveniently  practicable (the "Liquidation Date"),  the Existing Warburg
Fund will  liquidate  and distribute  pro  rata to  the  Existing   Warburg
Fund's shareholders  of record  determined  as of the close of  business on
the Closing Date (the "Existing Warburg Fund Shareholders")  the New Warburg
Fund Shares it receives  pursuant to paragraph 1.1. Such liquidation and
distribution  will be accomplished by the transfer of the New Warburg Fund
Shares then credited to the account of the  Existing Warburg  Fund on the
books of the New Warburg Fund to open  accounts on the share  records of the
New Warburg  Fund in the name of the Existing Warburg Fund's shareholders
representing the respective pro rata number of the New Warburg Fund Shares of
the  particular  class due such  shareholders.  All issued  and   outstanding
shares  of  the Existing   Warburg  Fund  will simultaneously  be  canceled
on the  books  of the  RBB  Fund,  although share certificates  representing
interests in the Existing Warburg Fund will represent a number of New Warburg
Fund Shares after the Closing  Date as determined  in accordance  with Section
2.3. The New Warburg Fund shall not issue  certificates representing the New
Warburg Fund Shares in connection with such exchange.

         1.5. Ownership of New Warburg Fund Shares will be shown on the books
of the New Warburg Fund's  transfer  agent.  Shares of the New Warburg Fund
will be issued in the manner described in the New Warburg Fund's current
prospectus and statement of additional information.

         1.6.     Any transfer taxes payable upon issuance of the New Warburg
Fund Shares in a name other than the registered holder of

<PAGE>4


the Existing  Warburg Fund Shares on the books of the Existing  Warburg
Fund as of that time shall,  as a condition of such  issuance and  transfer,  be
paid by the  person to whom such New  Warburg  Fund  shares are to be issued and
transferred.

         1.7. Any reporting  responsibility  of the Existing Warburg Fund is and
shall  remain  the  responsibility  of the  RBB  Fund  up to and  including  the
applicable  Closing Date and such later dates on which the Existing Warburg Fund
is terminated.

2.       VALUATION

         2.1. The value of the  Existing  Warburg  Fund's  assets to be acquired
hereunder  shall be the value of such assets computed as of the close of regular
trading on the New York Stock  Exchange,  Inc.  (the  "NYSE") on the  applicable
Closing Date (such time and date being hereinafter called the "Valuation Date"),
using the valuation  procedures  set forth in the Existing  Warburg  Fund's then
current prospectus or statement of additional information.

         2.2.  The net asset  value of each  class of Shares of the New  Warburg
Fund shall be the net asset value per share  computed as of the Valuation  Date,
using the valuation  procedures set forth in the New Warburg Fund's then current
prospectus or statement of additional information.

         2.3.  The number of Shares of each class of the New Warburg  Fund to be
issued  (including  fractional  shares,  if any) in  exchange  for the  Existing
Warburg  Fund's net assets shall be  determined by dividing the value of the net
assets of the Existing  Warburg Fund  attributable to the respective  classes of
Shares determined using the same valuation  procedures  referred to in paragraph
2.1 by the net  asset  value  per Share of such  class of the New  Warburg  Fund
determined in accordance with paragraph 2.2.

         2.4.     All computations of value shall be made by PFPC Inc. in
accordance with its regular practice as pricing agent for the Existing Warburg
Fund and New Warburg Fund, respectively.

3.       CLOSING AND CLOSING DATE
   
         3.1. The Closing Date for the  Reorganization  shall be May 3, 1996, or

provided.  The  Closing  shall be held as of 4:00 p.m.,  at the  offices of PFPC

necessary  taxes,  including  all  applicable  federal and state stock  transfer
stamps,  if any,  shall have been paid, or provision for payment shall have been
made, in conjunction with the delivery of portfolio securities.

         3.3.  In the event that on the  Valuation  Date (a) the NYSE or another
primary  trading market for portfolio  securities of the New Warburg Fund or the
Existing  Warburg  Fund shall be closed to trading or trading  thereon  shall be
restricted  or (b) trading or the  reporting of trading on the NYSE or elsewhere
shall be disrupted so that accurate  appraisal of the value of the net assets of
the New  Warburg  Fund  or the  Existing  Warburg  Fund  is  impracticable,  the
applicable  Closing Date shall be postponed  until the first  business day after
the day when trading shall have been fully resumed and reporting shall have been
restored.

         3.4.  The RBB Fund,  on  behalf of the  Existing  Warburg  Fund,  shall

RBB Fund that such New Warburg  Fund Shares have been  credited to the  Existing
Warburg  Fund's  account on the books of the New Warburg  Fund.  At the Closing,
each party  shall  deliver to the  relevant  other  parties  such bills of sale,
checks, assignments,  share certificates, if any, receipts or other documents as
such other party or its counsel may reasonably request.

Director  or  Officer  ("Indemnified  Person")  of the RBB Fund,  against  money
damages  actually  and  reasonably   incurred  by  such  Indemnified  Person  in
connection with any claim

<PAGE>12

   
that is asserted  against such  Indemnified  Person arising out of such
person's  service  as a  director  or  officer  of the RBB Fund with  respect to
matters  specifically  relating to the Existing Warburg Fund, provided that such
indemnification  and  advancement  of expenses shall be permitted to the fullest
extent that is available  under the Maryland  General  Corporation law and other
applicable  law.  This  paragraph  5.10 shall not protect  any such  Indemnified
Person against any liability to the Existing  Warburg Fund, the New Warburg Fund
or their  shareholders  to which he would  otherwise  be  subject  by  reason of
willful  misfeasance,  bad faith, gross negligence or from reckless disregard of
the duties involved in the conduct of his office. An Indemnified  Person seeking
indemnification  shall be  entitled to  advances  from the New Warburg  Fund for
payment of the reasonable expenses incurred by him in connection with the matter
as to which he is  seeking  indemnification  in the  manner  and to the  fullest
extent  permissible  under  the  Maryland  General  Corporation  law  and  other
applicable law. Such Indemnified  Person shall provide to the New Warburg Fund a
written  affirmation  of his good  faith  belief  that the  standard  of conduct
necessary for indemnification by the New Warburg Fund has been met and a written
undertaking to repay any advance if it should  ultimately be determined that the
standard of conduct has not been met. In addition, at least one of the following
additional  conditions  shall be met: (a) the  Indemnified  Person shall provide
security  in  form  and  amount  acceptable  to the  New  Warburg  Fund  for its
undertaking;  (b) the New  Warburg  Fund is insured  against  losses  arising by
reason of the  advance;  or (c) either a majority  of a quorum of  disinterested
non-party  directors of the New Warburg Fund  (collectively,  the "Disinterested
Directors"),  or independent  legal counsel  experienced in mutual fund matters,
selected by the Indemnified Person, in a written opinion, shall have determined,
based on a review of facts readily available to the New Warburg Fund at the time
the  advance is proposed  to be made,  that there is reason to believe  that the
Director will ultimately be found to be entitled to indemnification.

be  shown;  (g)  such  counsel  does not know of any  legal,  administrative  or
governmental proceedings,  investigation, order, decree or judgment of any court
or governmental body, only insofar as they relate to the New Warburg Fund or its
assets or properties, pending, threatened or otherwise existing on or before the

<PAGE>18


                  (a) they are independent  public  accountants  with respect to
the RBB Fund within the meaning of the 1933 Act and the  applicable  regulations
thereunder;

                  (b) in their opinion,  the financial  statements and per Share

by reference in the Registration  Statement and reported on by them comply as to
form in all material aspects with the applicable accounting  requirements of the
1933 Act and the rules and regulations thereunder;

                  (c) on the basis of limited  procedures agreed upon by the New
Warburg Fund and the RBB Fund and  described in such letter (but not an audit in
accordance  with  generally  accepted  auditing  standards)  with respect to the
unaudited pro forma financial  statements of the Existing  Warburg Fund included
in the  Registration  Statement  and  the  Proxy  Statement,  and  inquiries  of
appropriate officials of the RBB Fund or the director(s) thereof responsible for
financial and accounting  matters,  nothing came to their attention which caused
them to believe that (i) such  unaudited pro forma  financial  statements do not
comply  as to form in all  material  respects  with  the  applicable  accounting
requirements of the 1933 Act and the rules and regulations  thereunder,  or (ii)
such  unaudited  pro forma  financial  statements  are not fairly  presented  in
conformity  with generally  accepted  accounting  principles  applied on a basis
substantially consistent with that of the audited financial statements; and

                  (d) on the basis of limited  procedures agreed upon by the New
Warburg  Fund  and  the RBB  Fund  and  described  in such  letter  (but  not an
examination  in accordance  with generally  accepted  auditing  standards),  the
information  relating to the Existing Warburg Fund appearing in the Registration
Statement and the Proxy Statement that is expressed in dollars or percentages of
dollars (with the exception of performance  comparisons)  has been obtained from
the accounting  records of such Existing Warburg Fund or from schedules prepared
by officers of the RBB Fund having  responsibility  for  financial and reporting
matters and such  information  is in agreement  with such records,  schedules or
computations made therefrom.
   
         7.6.  The RBB  Fund  shall  have  delivered  to the New  Warburg  Fund,

         7.7.  The New Warburg Fund shall have  received  from Coopers & Lybrand
LLP a letter  addressed to the New Warburg  Fund and dated as of the  applicable
Closing  Date  stating  that as of a date no more than three (3)  business  days
prior to the applicable  Closing Date,  Coopers & Lybrand LLP performed  limited
procedures in  connection  with the RBB Fund's most recent  unaudited  financial
statements  and that (a) nothing  came to their  attention  in  performing  such
limited procedures or otherwise that led them to

<PAGE>19

   
believe that there had been any changes in the assets, liabilities, net
assets,  net  investment  income,  net  increase  (decrease)  in net assets from
operations or net increase  (decrease) in net assets as compared with amounts as
of the  Existing  Warburg  Fund's  most  recent  audited  fiscal year end or the
corresponding  period in the Existing  Warburg Fund's most recent audited fiscal
year, other than changes  occurring in the ordinary course of business,  and (b)
based on such limited procedures, there is no change in their report on the most
recent audited financial statements of such Existing Warburg Fund.
    
         7.8. The Board of  Directors  of the RBB Fund,  including a majority of
the  directors who are not  "interested  persons" of the RBB Fund (as defined by
the 1940 Act),  shall have determined  that this Agreement and the  transactions
contemplated  hereby are in the best  interests of the RBB Fund and the Existing
Warburg Fund and that the interests of the  shareholders in the RBB Fund and the
Existing Warburg Fund would not be diluted as a result of such transactions, and
the RBB Fund shall have  delivered  to the New  Warburg  Fund at the  applicable
Closing, a certificate, executed by an officer, to the effect that the condition
described in this subparagraph has been satisfied.

paragraph 5.2 hereof and (vi) any other Reorganization expenses.
   
         9.3. (a) Warburg  agrees to indemnify and hold harmless each person who
at the time of execution  of this  Agreement is a director or officer of the RBB
Fund (a  "Warburg  Indemnified  Party")  from and against any and all direct and
indirect liabilities,  losses, claims, damages and expenses (including,  without
limitation,  reasonable  attorneys'  fees)  ("Losses")  incurred  by  a  Warburg
Indemnified Party and that arise from or relate to the operations  commencing on
the first business day
    
<PAGE>22


after the Closing Date of the New Warburg  Fund.  This  indemnification
provision  shall only cover  Losses that have not been  recovered by the Warburg
Indemnified Party against the New Warburg Fund after a reasonable period of time
following a written request to do so by the Warburg Indemnified Party.

          (b) Warburg's  agreement to indemnify the Warburg  Indemnified Parties
pursuant to this paragraph 9.3 is expressly  conditioned  upon  Warburg's  being
promptly  notified of any action or claim  brought  against any such party after
the Warburg  Indemnified  Party receives notice of the action.  The failure of a
Warburg  Indemnified  Party to notify Warburg shall not relieve Warburg from any
liability   that   Warburg   may  have   otherwise   than  on  account  of  this
indemnification agreement.

          (c) In case any action or claim  shall be brought  against any Warburg
Indemnified  Party  and it  shall  timely  notify  Warburg  of the  commencement
thereof, Warburg shall be entitled to participate in, and, to the extent that it
shall wish to do so, to assume the defense thereof with counsel  satisfactory to
it. If Warburg  opts to assume the defense of such  action,  Warburg will not be
liable  to the  Warburg  Indemnified  Party  for any  legal  or  other  expenses
subsequently  incurred by the Warburg  Indemnified  Party in connection with the
defense  thereof  other  than  (1)  reasonable  costs  of  investigation  or the
furnishing of documents or witnesses and (2) all reasonable fees and expenses of
separate counsel to such Warburg  Indemnified  Party if the Warburg  Indemnified
Party shall have concluded  reasonably  that  representation  of Warburg and the
Warburg  Indemnified  Party by the same counsel  would be  inappropriate  due to
actual or  potential  differing  interests  between  them in the  conduct of the
defense of such action.

10.  ENTIRE AGREEMENT; SURVIVAL OF WARRANTIES

         10.1.  The New Warburg  Fund and the RBB Fund,  itself and on behalf of
the Existing Warburg Fund, agree that neither party has made any representation,
warranty or covenant  not set forth herein and that this  Agreement  constitutes
the entire agreement among the parties.

         10.2. The  representations,  warranties and covenants contained in this
Agreement or in any document delivered pursuant hereto or in connection herewith
shall survive the consummation of the transactions contemplated hereunder.

11.  TERMINATION

         11.1.  This  Agreement may be terminated at any time at or prior to the
Closing Date by: (1) mutual agreement of the RBB Fund, on behalf of the Existing
Warburg  Fund,  and the New  Warburg  Fund;  (2) the RBB Fund,  on behalf of the
Existing  Warburg  Fund,  in the event the New Warburg  Fund  shall,  or the New
Warburg Fund in the event the RBB Fund or the Existing Warburg Fund shall,

<PAGE>23


materially breach any  representation,  warranty or agreement contained
herein to be performed at or prior to the Closing  Date; or (3) the RBB Fund, on
behalf of the Existing Warburg Fund, or the New Warburg Fund, or the New Warburg
Fund  in  the  event  a  condition  herein  expressed  to be  precedent  to  the
obligations  of the  terminating  party  or  parties  has  not  been  met and it
reasonably appears that it will not or cannot be met.

         11.2. In the event of any such termination, there shall be no liability
for damages on the part of either the New Warburg Fund or the RBB Fund, or their
respective directors or officers, to the other party or parties.

12.  AMENDMENTS

         This Agreement may be amended,  modified or  supplemented in writing in
such manner as may be mutually agreed upon by the authorized officers of the New
Warburg Fund and the RBB Fund; provided,  however, that following the meeting of
the Existing  Warburg  Fund's  shareholders  called by the RBB Fund  pursuant to
paragraph  5.2 of this  Agreement  no such  amendment  may  have the  effect  of
changing  the  provisions  for  determining  the number of the New Warburg  Fund
Shares to be issued to the  Existing  Warburg  Fund's  Shareholders  under  this
Agreement to the detriment of such shareholders without their further approval.

Warburg, Pincus Tax Free Fund, Inc.
466 Lexington Avenue
New York, New York 10017-3174

Ladies and Gentlemen:

We have acted as  counsel to  Warburg,  Pincus Tax Free Fund,  Inc.,  a Maryland
corporation (the "Acquiring Fund"), in connection with the proposed  acquisition
by the Acquiring Fund of all or substantially  all of the assets and liabilities
of Warburg Pincus Tax Free Fund (the "Acquired Fund"), a series of The RBB Fund,
Inc., a Maryland  corporation (the "RBB Fund"), in exchange for Common shares of
the Acquiring Fund (the "Common  Shares"),  pursuant to an Agreement and Plan of
Reorganization  to be executed by the  Acquiring  Fund,  and by the RBB Fund, on
behalf of the Acquired Fund (the "Plan").

We have  examined  the  Acquiring  Fund's  Registration  Statement  on Form N-14
substantially in the form in which it is to become effective (the  "Registration
Statement"),  the Acquiring Fund's Articles of Incorporation and Bylaws, and the
Plan.

We have also  examined and relied upon other  documents  and  certificates  with
respect to factual  matters as we have  deemed  necessary  to render the opinion
expressed  herein.  We  have  assumed,  without  independent  verification,  the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity with originals of all documents  submitted to us
as copies.  We have further assumed that the Plan  constitutes the legal,  valid
and  binding  obligation  of the RBB Fund,  enforceable  against the RBB Fund in
accordance  with its terms. As to matters of Maryland law, we have relied solely
on the opinion of Venable,  Baetjer and Howard,  LLP with respect to the matters
addressed  therein,  which is satisfactory to us in form and scope and a copy of
which is annexed hereto.

Anything in this opinion to the contrary notwithstanding,  we render or imply no
opinion with respect to compliance with any applicable  securities or anti-fraud
statutes,  rules,  regulations  or other  similar  laws of any state  (including
Maryland) or the United States of America.  In rendering the opinions herein, we
assume that there will be no  material  changes in the facts and  conditions  on
which we base such opinions  between the date hereof and the time of issuance of
the Acquiring Fund Shares pursuant to the Agreement.

Based upon the foregoing, we are of the opinion that:

                  1.  The Acquiring Fund is a corporation validly existing and
in good standing under the laws of the State of Maryland.

                  2. The  Common  Shares of the  Acquiring  Fund to be issued as
contemplated  in the Plan have  been,  to the extent of the number of the shares
authorized  in the  Articles of  Incorporation  of the  Acquiring  Fund and then
unissued, duly authorized,  and, subject to the receipt by the Acquiring Fund of
consideration  equal to the net asset value  thereof  (but in no event less than
the par value thereof), when issued in accordance with the Plan, will be validly
issued,  fully paid and nonassessable  Common Shares of the Acquiring Fund under
the laws of the State of Maryland.

We  hereby  consent  to  the  filing  of  this  opinion  as an  exhibit  to  the
Registration  Statement,  to  the  references  to  us  in  the  Prospectus/Proxy
Statement  included as part of the  Registration  Statement and to the filing of
this  opinion  as an  exhibit  to any  application  made by or on  behalf of the
Acquiring Fund or any distributor or dealer in connection with the  registration
or qualification of the Acquiring Fund or the Common Shares under the securities
laws of any state or other jurisdiction.

This opinion is furnished by us as counsel to the Acquiring  Fund, is solely for
the benefit of the Acquiring Fund and its governing board in connection with the
above  described  acquisition of assets and may not be relied upon for any other
purpose or by any other person.

Very truly yours,

/s/ Willkie Farr & Gallagher

         RE:      WARBURG, PINCUS TAX FREE FUND, INC.

Ladies and Gentlemen:

         We have acted as special Maryland  counsel to Warburg,  Pincus Tax Free
Fund, Inc., a Maryland  corporation (the "Acquiring  Fund"),  in connection with
the proposed  acquisition by the Acquiring Fund of all or substantially  all the
assets and liabilities of Warburg Pincus Tax Free Fund (the "Acquired  Fund"), a
portfolio of The RBB Fund,  Inc. (the "RBB Fund"),  a Maryland  corporation,  in
exchange for Common shares of the Acquiring Fund (the "Common Shares"), pursuant
to an Agreement and Plan of  Reorganization to be executed by the Acquiring Fund
and by the RBB Fund on behalf of the Acquired Fund (the "Plan").

         We have examined the Acquiring  Fund's  Registration  Statement on Form
N-14  substantially  in the form in which it is to become  effective  (the "N-14
Registration  Statement"),  the Acquiring Fund's Articles of  Incorporation  and
Bylaws,  and the Plan substantially in the form in which it is to be attached to
the Prospectus/Proxy  Statement included in the N-14 Registration  Statement. We
have  further  examined  and relied upon a  certificate  of the  Maryland  State
Department of Assessments  and Taxation to the effect that the Acquiring Fund is
duly incorporated and existing under the laws of the State of Maryland and is in
good standing and duly authorized to transact business in the State of Maryland.

         We have also examined and relied upon other documents and  certificates
with  respect to factual  matters  and we have  deemed  necessary  to render the
opinion expressed herein. We have assumed, without independent verification, the
genuineness of all signatures, the authenticity of all documents submitted to us
as

originals, and the conformity with originals of all documents submitted to us as
copies.  We have further assumed that the Plan constitutes the legal,  valid and
binding  obligation  of the  RBB  Fund,  enforceable  against  the  RBB  Fund in
accordance with its terms, and, further,  that the number of Common Shares to be
issued by the Acquiring  Fund and then  distributed to the  shareholders  of the
Acquired Fund pursuant to the Plan will not exceed the respective number of then
unissued Common Shares of the Acquiring Fund authorized in the Acquiring  Fund's
Articles of Incorporation.

         Based upon the foregoing, we are of the opinion that:

         1.       The Acquiring Fund is a corporation validly existing and in
good standing under the laws of the State of Maryland.

         2. The Common Shares of the Acquiring Fund to be issued as contemplated
in the Plan have been,  to the extent of the number of shares of the  respective
class authorized in the Articles of Incorporation of the Acquiring Fund and then
unissued, duly authorized,  and, subject to the receipt by the Acquiring Fund of
consideration  equal to the net asset value  thereof  (but in no event less than
the par value thereof),  when issued in accordance with the Plan will be validly
issued,  fully paid and nonassessable  Common Shares of the Acquiring Fund under
the laws of the State of Maryland.

         This letter  expresses our opinion with respect to the Maryland General
Corporation  Law  governing  matters such as the  authorization  and issuance of
stock.  It does not extend to the securities of "blue sky" laws of Maryland,  to
federal securities laws or to other laws.

         You may rely on our foregoing  opinion in rendering your opinion to the

Statement.  We consent  to the filing of this  opinion as an exhibit to the N-14
Registration Statement and the reference to us under the caption "Legal Matters"

Ladies and Gentlemen:

You  have  asked  us for our  opinion  concerning  certain  federal  income  tax
consequences to (a) Warburg Pincus Growth & Income Fund, Warburg Pincus Balanced
Fund,  and Warburg Pincus Tax Free Fund (each,  an "Existing  Warburg Fund" and,
collectively,  the "Existing Warburg Funds"),  each a separate series of The RBB

(each, a "New Warburg Fund" and, collectively,  the "New Warburg Funds") and (c)
holders of shares of common stock in each of the Existing Warburg Funds when the
holders of shares in each of the Existing Warburg Funds receive shares of common
stock of each  corresponding  New Warburg Fund in liquidation of their interests
in the Existing  Warburg  Funds  pursuant to an  acquisition  by each of the New
Warburg  Funds of all or  substantially  all of the assets of the  corresponding
Existing Warburg Fund in exchange for the shares of the New Warburg Fund and the
assumption  by the New Warburg  Fund of  scheduled  liabilities  of the Existing
Warburg Fund and the  subsequent  liquidation  of the Existing  Warburg Fund and
distribution  in  liquidation  of the  shares  of the  New  Warburg  Fund to the
shareholders of the Existing Warburg Fund (the  "Reorganization"),  all pursuant
to an agreement and plan of reorganization.

We have reviewed such  documents and materials as we have  considered  necessary
for the purpose of rendering this opinion.  In rendering this opinion, we assume
that such  documents  as yet  unexecuted  will,  when  executed,  conform in all
material respects to the proposed forms of such documents that we have examined.
In addition,  we assume the genuineness of all signatures,  the capacity of each
party executing a document so to execute that document,  the authenticity of all
documents  submitted to us as originals and the conformity to original documents
of all documents submitted to us as certified or photostatic copies.

We have made  inquiry  as to the  underlying  facts  which we  considered  to be
relevant to the conclusions set forth in this letter.  The opinions expressed in
this letter are based upon certain factual  statements  relating to the Existing
Warburg Funds and the New Warburg Funds set forth in the Registration Statements
on Form N-14 (the  "Registration  Statements")  filed by each of the New Warburg
Funds with the Securities and Exchange Commission and representations to be made
in letters from the RBB Fund, on behalf of each Existing  Warburg Fund, and each
of the New  Warburg  Funds  addressed  to us for our  use in  rendering  a final
opinion.  Based on  information  received and  expected to be received  from the
Existing  Warburg Funds and the New Warburg Funds,  we have no reason to believe
that we will  not be able to  render  this  opinion  as a final  opinion  at the
Closing. We have no reason to believe that these  representations and facts will
not be  valid,  but we have  not  attempted  and  will  not  attempt  to  verify
independently any of these  representations and facts, and this opinion is based
upon the assumption that each of them is accurate. Capitalized terms used herein
and not otherwise  defined shall have the meaning given them in the Registration
Statements.

The  conclusions  expressed  herein are based upon the Internal  Revenue Code of
1986 (the "Code"), Treasury regulations issued thereunder, published rulings and
procedures of the Internal  Revenue  Service and judicial  decisions,  all as in
effect on the date of this letter.

Based upon the foregoing, it is our opinion that:



<PAGE>
March 5, 1996
Page 3


          (1) the transfer of all or substantially  all of each Existing Warburg
Fund's assets in exchange for the  corresponding  New Warburg  Fund's shares and
the assumption by the New Warburg Fund of certain  scheduled  liabilities of the
Existing Warburg Fund will constitute a  "reorganization"  within the meaning of
Section  368(a)(1)(F)  of the  Code,  and  the  Existing  Warburg  Fund  and the
corresponding New Warburg Fund are each a "party to a reorganization" within the
meaning of Section 368(b) of the Code;

          (2) no gain or loss will be  recognized  by any New Warburg  Fund upon
the receipt of the assets of the corresponding Existing Warburg Fund in exchange
for the New Warburg  Fund's shares and the assumption by the New Warburg Fund of
certain scheduled liabilities of the corresponding Existing Warburg Fund;

          (3) no gain or loss will be  recognized  by any Existing  Warburg Fund
upon the  transfer  of its  assets  to the  corresponding  New  Warburg  Fund in
exchange for the New Warburg Fund's shares and the assumption by the New Warburg
Fund of certain  scheduled  liabilities of the Existing Warburg Fund or upon the
distribution  (whether actual or  constructive) of the New Warburg Fund's shares
to the Existing Warburg Fund's shareholders;

          (4) no gain or loss will be recognized by an Existing  Warburg  Fund's
shareholders upon the exchange of their shares for the corresponding New Warburg
Fund's shares and the  assumption by the New Warburg Fund of  liabilities of the
Existing Warburg Fund;

          (5) the  aggregate  tax basis of the  shares of the New  Warburg  Fund
received  by each  shareholder  of an  Existing  Warburg  Fund  pursuant  to the
Reorganization  will be the same as the aggregate tax basis of the shares of the
Existing Warburg Fund surrendered therefor, and the holding period of the shares
of the New  Warburg  Fund to be  received by each  shareholder  of the  Existing
Warburg  Fund will  include the period  during  which the shares of the Existing
Warburg Fund  exchanged  therefor  were held by such  shareholder  (provided the
shares of the Existing  Warburg Fund were held as capital  assets on the date of
the Reorganization); and

             (6)     the tax basis to the New Warburg Fund of the
corresponding Existing Warburg Fund's assets acquired by

<PAGE>
March 5, 1996
Page 4


the New  Warburg  Fund will be the same as the tax  basis of such  assets to the
Existing Warburg Fund immediately prior to the  Reorganization,  and the holding
period  of the  assets  of the  Existing  Warburg  Fund in the  hands of the New
Warburg Fund will include the period  during which those assets were held by the
Existing Warburg Fund.

We  hereby  consent  to the  filing  of  this  opinion  as an  exhibit  to  each
Registration  Statement and to the use of our name and any reference to our firm
in each Registration Statement or in the Prospectus/Proxy Statement constituting
a part thereof.
