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
