EXHIBIT 4.3  


 
  AMENDMENT NO. 1 TO THE RIGHTS AGREEMENT    
    



        This Amendment No. 1 (this "Amendment") is entered into as of June 29, 2003, between INFORMATION RESOURCES, INC., a Delaware corporation (the
"Company"), and HARRIS TRUST AND SAVINGS BANK (the "Rights Agent"), to the Rights Agreement between the Company and Harris Trust and Savings Bank, amended and restated on October 27, 1997 (the
"Rights Agreement"). All capitalized terms not defined herein shall have the meanings ascribed to such terms in the Rights Agreement. 


        WHEREAS, the Company proposes to enter into (a) an Agreement and Plan of Merger, dated as of June 29, 2003 (as amended,
supplemented, modified or replaced from time to time, the "Merger Agreement"), among Gingko Corporation, a Delaware corporation ("Parent"), Gingko Acquisition Corp., a Delaware corporation and a
direct, wholly-owned subsidiary of Parent ("Merger Sub"), and the Company and (b) the Contingent Value Rights Agreement to be entered into on the terms and subject to the conditions of the
Merger Agreement by and among Parent, the Company and the Rights Agents (as defined therein) (as amended, supplemented, modified or replaced from time to time, the "CVR Agreement"); 


        WHEREAS, the Board of Directors of the Company has determined that the Merger Agreement and the CVR Agreement and the terms and conditions
set forth therein and the transactions contemplated thereby, including, without limitation, the Offer, any exercise of the Top-Up Option, the Merger and the issuance of the CVRs (as such terms are
defined in the Merger Agreement), are advisable and are fair to and in the best interests of the Company and its stockholders; 



        WHEREAS, the Board of Directors of the Company has determined, in connection with its contemplation of the Merger Agreement and the CVR
Agreement, that it is necessary and desirable to amend the Rights Agreement to exempt the Merger Agreement and the CVR Agreement and the transactions contemplated thereby, including, without
limitation, the Offer, any exercise of the Top-Up Option, the Merger and the issuance of the CVRs, from the application of the Rights Agreement as set forth in this Amendment; 


        WHEREAS, Section 26 of the Rights Agreement provides that the Company and the Rights Agent may at any time supplement or amend the
Rights Agreement without the approval of any holders of Rights Certificates in order, among other things, to effect any change or modification which the Company may deem necessary or desirable; and 


        WHEREAS, pursuant to Section 26, the Company hereby directs that the Rights Agreement should be amended as set forth in this
Amendment. 


        NOW THEREFORE, in consideration of the foregoing premises and mutual covenants and agreements set forth herein, and other good and
valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the Rights Agent hereby agree as follows:

Offer, any exercise of the Top-Up Option, the consummation of the Merger, or the issuance of the CVRs pursuant to the Offer or the Merger (as such terms are defined in the Merger Agreement), (iii) the consummation of any other transaction
