TELEPHONE SCRIPT

Hello, this is _____ calling from Robeco USA, Inc. I am calling to let you know
that you and/or your clients will be receiving a prospectus supplement in the
mail regarding the proposed reorganization of each of the WPG mutual funds into
a newly created series of The RBB Fund, Inc., a Maryland Corporation. If the
reorganizations are approved by the shareholders of each fund, it is expected
that the reorganizations will be completed on or about April 22, 2005. The
successor funds to all three WPG funds, WPG Core Bond Fund, WPG Tudor Fund and
WPG Large Cap Growth Fund will be changed to include "Robeco." For example, the
name of the successor to the WPG Core Bond Fund will be Robeco WPG Core Bond
Fund.

It is expected that there will be no material changes to the investment
objectives, policies and strategies of any of the successor funds as a result of
the reorganizations. In addition, Robeco USA, L.L.C., through its division
Weiss, Peck & Greer Investments, will continue to serve as investment adviser to
the funds on substantially the same terms as it currently serves for the WPG
funds.

THE WPG FUNDS AND THE SUCCESSOR FUNDS WILL SEND A COMBINED PROSPECTUS/PROXY
STATEMENT TO THE SHAREHOLDERS OF THE WPG FUNDS DESCRIBING IN GREATER DETAIL THE
PROPOSED REORGANIZATIONS AND THE SUCCESSOR FUNDS PRIOR TO THE SHAREHOLDER
MEETING TO VOTE ON APPROVING THE REORGANIZATION. PLEASE READ THE COMBINED
PROSPECTUS/PROXY STATEMENT CAREFULLY WHEN IT IS AVAILABLE BECAUSE IT CONTAINS
IMPORTANT INFORMATION. COPIES OF THE COMBINED PROSPECTUS/PROXY STATEMENT, WHEN
FILED WILL BE, AND OTHER DOCUMENTS FILED BY THE RBB FUND, INC. AND THE WPG FUNDS
ARE CURRENTLY, AVAILABLE FREE OF CHARGE ON THE SECURITIES AND EXCHANGE
COMMISSION'S WEBSITE AT WWW.SEC.GOV, OR FROM THE WPG FUNDS OR THE RBB FUND, INC.

Should you have any additional questions when you receive the prospectus
supplement, please let me know. My phone number is ____.

Have a happy holiday!
