                         SUPPLEMENT TO PROXY STATEMENT
                              ____________________

     This Supplement provides additional information with respect to the Annual
Meeting of Stockholders (the "Annual Meeting") of Infinium Software, Inc. (the
"Company") to be held on Friday, February 11, 2000, at 3:00 p.m., Boston Time,
at The Marriott Long Wharf, 296 State Street, Boston, Massachusetts 02109, for
the purposes set forth in the Notice of Annual Meeting of Stockholders dated
January 11, 2000.

     The Proxy Statement dated January 11, 2000 (the "Proxy Statement"), the
Company's Annual Report for the year ended September 30, 1999 and a proxy card
(the "White Proxy Card") were mailed on or about January 11, 2000, to all
stockholders entitled to vote at the Annual Meeting. This Supplement and the
enclosed blue proxy card (the "Blue Proxy Card") are being mailed on or about
February 1, 2000 to all stockholders entitled to vote at the Annual Meeting.
Stockholders are asked to execute and return BOTH the White Proxy Card and the
Blue Proxy Card.

     All proxies will be voted in accordance with the instructions contained
therein, and if no choice is specified, the proxies will be voted in favor of
the proposals set forth in the Proxy Statement and this Supplement. Any proxy
may be revoked by a stockholder at any time before it is exercised by giving
written notice to that effect to the Clerk of the Company.

     Except as specifically amended or supplemented by the information contained
in this Supplement, all information set forth in the Proxy Statement remains
accurate and should be considered in casting your vote by proxy or at the Annual
Meeting.

                             PURPOSE OF SUPPLEMENT

     The purpose of this Supplement is to add a nominee for election as a Class
I director to serve for a three-year term or until his successor is elected and
qualified. This nominee stands in addition to Manuel Correia, the nominee
currently proposed by the Company in the Proxy Statement for election at the
Annual Meeting.

     The Board of Directors has nominated and recommended that Fred Luconi, who
was appointed as a Class I director on February 1, 2000, be elected as a Class I
director, to hold office until the Annual Meeting of Stockholders to be held in
2003 or until his successor has been duly elected and qualified or until his
earlier resignation or removal. There are currently two Class I directors, Mr.
Luconi and Manuel Correia. Please note that the Board of Directors has nominated
and recommended Mr. Correia in the Proxy Statement for election as a Class I
director. Your submission of the enclosed Blue Proxy Card will not revoke or
modify any proxy you granted on the White Proxy Card solicited by the Proxy
Statement


     Mr. Luconi was appointed by the Board of Directors as a non-employee
director to fill a vacancy in one of the Class I director positions. For the
last five years, Mr. Luconi has been a self-employed consultant and venture
investor. Mr. Luconi is 58 years old.

     The information in the Proxy Statement under the caption " Stock Ownership
of Certain Beneficial Owners and Management" and the information under the
caption "Amount and Nature of Beneficial Ownership" is supplemented by
Mr. Luconi's share ownership information. As of February 1, 2000, Mr. Luconi was
granted an option to purchase 28,000 shares, which will be exercisable over a
four-year period at the rate of 25% per year, at an exercise price equal to the
market price of the Common Stock at the close of business on February 1, 2000.
In addition, pursuant to the Company's 1995 Non-Employee Director Stock Option
Plan (the "Director Plan"), and in connection with the Annual Meeting, Mr.
Luconi will receive an additional option grant to purchase 4,000 shares of
Common Stock, which will be exercisable over a four-year period at the rate of
25% per year. The exercise price per share for all options granted under the
Director Plan will be equal to the market price of the Common Stock on the date
of grant.

                               PROCEDURAL MATTERS

     WHETHER OR NOT YOU HAVE RETURNED THE WHITE PROXY CARD PREVIOSULY SOLICITED
AND WHETHER OR NOT YOU EXPECT TO ATTEND THE ANNUAL MEETING, WE URGE YOU TO
COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED BLUE PROXY CARD AS PROMPTLY AS
POSSIBLE.

     Returning the enclosed Blue Proxy Card will not revoke any proxy granted by
executing the White Proxy Card previously distributed with the Proxy Statement.
The enclosed Blue Proxy Card is and will be considered a supplemental
submission.

                            YOUR VOTE IS IMPORTANT
