FIRST AMENDMENT TO THE RIGHTS AGREEMENT

Exhibit 4.1

FIRST AMENDMENT TO THE RIGHTS AGREEMENT

First Amendment (the “Amendment”), dated as of June 2, 2005, between Lawson Software, Inc., Inc., a Delaware corporation (the “Company”), and Mellon Investor Services LLC, as rights agent (the “Rights Agent”), to the Rights Agreement dated as of July 28, 2004 (the “Rights Agreement”); capitalized terms used without definition in this Amendment shall have the meanings given to them in the Rights Agreement.

WHEREAS, pursuant to Section 27 of the Rights Agreement, the Company, prior to the time that any Person becomes an Acquiring Person, may from time to time change or supplement the Rights Agreement in order to make any changes which the Company may deem necessary or desirable;

WHEREAS, the Company has organized Lawson Holdings, Inc. as its wholly-owned subsidiary (“Lawson Holdings”), and the Company has caused Lion Holdings to organize Lawson Acquisition, Inc. (“Lawson Acquisition”) for the purpose of reorganizing Lawson Holdings into a holding company through a merger of Lawson Acquisition with and into the Company, with the Company as the surviving corporation and a wholly-owned subsidiary of Lawson Holdings (the “Merger”);

WHEREAS, it is contemplated that Lawson Holdings will make a public offer for all outstanding Series A and Series B shares of Intentia AB (“Intentia”), all outstanding warrants to purchase Series B shares of Intentia and all outstanding 5% Convertible Subordinated Notes due 2006 of Intentia (collectively, the “Offer”);

WHEREAS, in conjunction with the Offer, certain Company affiliates have entered into agreements to vote in favor of the Merger and the issuance of Lion Holdings common stock in connection with the Offer, to vote against any competing acquisition proposals, not to transfer any of their Company common stock and not to solicit competing proposals for the acquisition of the Company (collectively, the “Irrevocable Undertakings”);

WHEREAS, the Board of Directors of the Company has determined that this Amendment is necessary and desirable to provide that the execution and delivery of the Irrevocable Undertakings, and any exercise by Intentia of its rights thereunder, shall not give rise to a Distribution Date under the Rights Agreement, and the Company and the Rights Agent desire to evidence such Amendment in writing; and

WHEREAS, no Person is an Acquiring Person as of the date hereof.

NOW THEREFORE, the parties hereto agree as follows:

1.                                       Amendment to Section 1 (Certain Definitions).

(a)                                  The definition of “Exempt Person” in Section 1 of the Rights Agreement is hereby amended by deleting it in its entirety and replacing it with the following:

5.                                       Counterparts.  This Amendment may be executed in any number of counterparts and each of such counterparts shall together constitute but one and the same instrument.

6.                                       Miscellaneous.  This Amendment shall be deemed a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed in accordance with the laws of such state; provided, however, that all provisions regarding the rights, duties, liabilities and obligations of the Rights Agent shall be governed by and construed in accordance with the laws of
