  Amendment 149
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 wish to make available additional products from DELMIA, update the royalties
for some of the previously licensed products, and correct the Attachment number for DELMIA
products. Whereas, the parties wish to amend the 1996 Agreement for the purpose of making the changes
associated with the foregoing. Now therefore, the parties agree to the following: 1.0  Section C. 14 DELMIA Products 1.1  In Amendments 138 and 145, the Attachment listing the DELMIA Products was incorrectly numbered
as
Attachment XXV DELMIA Products. Attachment XXV is the list of the SMARTEAM Products licensed to
IBM. The DELMIA Attachments in Amendments 138 and 145 are corrected to read Attachment XXVI
DELMIA Products. 1.2  Attachment XXVI DELMIA Products added by Amendment 145 is deleted and replaced with the
following updated Attachment XXVI DELMIA Products. This Attachment is the complete listing of all
DELMIA Licensed Programs, with changes to the prior version of the Attachment identified per the
legend. For the purpose of this Attachment, the term Bundle shall have the same meaning as
Configuration.
