Exhibit 4(a).1

Amendment 138

to the

Amended and Restated License Agreement

for the Use and Marketing of Programming Materials

dated May 31, 1996 (the “1996 Agreement”)

between

International Business Machines Corporation

and

Dassault Systemes, S.A.

This Amendment (“Amendment”) is entered into by and between International Business Machines Corporation (“IBM”), incorporated under the laws of the State of New York and Dassault Systemes, S.A. (“OWNER”), a French société anonyme.

Whereas, OWNER is the owner of 3D/2D Computer Aided Design/Computer Aided Manufacturing/Computer Aided Engineering/Product Integrated Management software programs marketed under various trademarks.

Whereas, the parties agreed in Amendment 125 to a pilot project for the DELMIA Products, and have now agreed to end the pilot project as originally defined and modify the basis on which they will work together regarding the DELMIA Products.

Whereas, the parties wish to make available additional products from DELMIA and update the list of licensed products and the list of DELMIA Named Accounts.

Whereas, the parties wish to amend the 1996 Agreement for the purposes of making the changes associated with the foregoing.

Now therefore, the parties agree to the following changes to Amendment 125:

1) The definition of “DELMIA Named Accounts” is changed to read as follows:

“DELMIA Named Accounts” shall mean those customers listed in Exhibit 1 to this Amendment, which the parties may amend from time to time, and any other customer(s) where OWNER requests, in writing, support from IBM and IBM agrees, in writing, to provide such support. The form of the written agreement may be by letter, email, or amendment to this Agreement and, for OWNER, can only be requested by either the DELMIA Corporation CEO or CFO

2) The term entitled “Materials and Services Provided by OWNER” subparagraph (c), is amended to change the first sentence to delete “for the DELMIA Products, participate with IBM and have a leadership role. . . .” and replace it with “for the DELMIA Products, the leadership role. . . .”

3) The Mode of Operation Document of Understanding (“MOO”) is deleted and replaced with the MOO attached to this Amendment as Exhibit II.

4) Section C.14.3.2(a) is amended to delete the beginning phrase “for sales to DELMIA Named Accounts. . . .” and replace it with “for sales of the DELMIA Products. . . .”

5) Section C.14.3.2(b) is deleted in its entirety.

6) With the end of the pilot project and the agreement by the parties to a different working relationship with respect to the DELMIA Products, Item 6.0 - Solicitation of Personnel, is amended to now read as follows:

“IBM agrees that the IBM Product Lifecycle Management organization will not directly or indirectly solicit for employment personnel of the Delmia Corporation, Delmia Gmbh, or any other Delmia company involved with the marketing and distribution of the Delmia Products associated with performance of this Amendment, unless expressly agreed to in writing by OWNER with respect to a particular employee; provided, however, that the parties agree to

Exhibit 4(a).1

review the foregoing on an annual basis to reasonably determine whether this Solicitation of Personnel provision should terminate based on the then-current Delmia product relationship Nothing in the foregoing prohibits IBM from giving consideration to any application for employment submitted on an unsolicited basis or in response to a general advertisement of employment opportunities.”

      7) The Term of Amendment 125 is changed to lengthen the term of each renewal period and now reads as follows:

“This Amendment is entered into effect as of November 1, 2000. Except for the rights, licenses and obligations of the parties with respect to [***] which shall have no end date, this Amendment shall continue until December 31, 2004, and will afterwards be automatically renewed for successive terms of one (1) year unless either party terminates it with a ninety (90) day notice period. In case of termination with respect to the DELMIA Named Accounts [***], all licenses granted by IBM for DELMIA Products shall continue in full force and effect under the terms and conditions of this Amendment, but IBM will no longer be authorized to grant any new licenses or add any DELMIA Products to existing licenses, [***] as of the date of termination. All terms of this Amendment will continue in full force and effect with respect to [***] until such time as the parties mutually agree to terminate such provisions.”

      8) Section C.14 DELMIA Products, is amended as follows:

a) Delete Attachments XXV and XXVI in their entirety and replace with this new Attachment XXV:
