announces that it commenced a cash tender offer for all of the issued
and outstanding shares of common stock of Exa Corporation (NASDAQ: EXA)
(“Exa”) for a price of $24.25 per share yesterday. The tender offer is
being made pursuant to an Offer to Purchase, dated October 12, 2017, and
in connection with the previously announced merger agreement, dated
September 27, 2017, among certain Dassault Systèmes’ subsidiaries and
Exa.

The tender offer will expire at 12:00 midnight, New York City time, on

business day after the previously scheduled expiration date.

Dassault Systèmes has filed a tender offer statement on Schedule TO with
the United States Securities and Exchange Commission (the “SEC”). 3DS
Acquisition 3 Corp., a US affiliate of Dassault Systèmes, is the
purchaser in the tender offer. The Offer to Purchase contained within
the Schedule TO sets out the terms and conditions of the tender offer.

Exa has also filed a Solicitation/Recommendation Statement with the SEC,
which includes, among other things, the recommendation of Exa’s board of
directors that Exa stockholders tender their shares in the tender offer.

As promptly as practicable following the completion of the tender offer,
Dassault Systèmes will acquire all remaining Exa shares through a merger
at the tender offer price.

The tender offer and the merger are subject to customary closing
conditions, including the tender of at least one share more than 50% of
the outstanding and issued shares of Exa (calculated on a fully-diluted
basis) and required regulatory approvals.
