ITEM 1.01    Entry into Material Definitive Agreement.

On June 5, 2008, Axway Inc., a Delaware corporation ("Axway") and an indirect wholly-owned subsidiary of the Sopra Group SA, a corporation organized under the laws of France (the "Sopra Group"), Tornado Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of Axway ("Merger Sub"), and Tumbleweed Communications Corp., a Delaware corporation ("Tumbleweed"), entered into an Agreement and Plan of Merger (the "Merger Agreement"), under which Merger Sub will be merged with and into Tumbleweed, with Tumbleweed continuing after the merger as the surviving corporation and a wholly-owned subsidiary of Axway (the "Merger").  In addition, the Sopra Group guaranteed the obligations of Axway and Merger Sub under the Merger Agreement.

Pursuant to the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of common stock, par value $0.001 per share, of Tumbleweed ("Tumbleweed Common Stock") will be converted into the right to receive $2.70 in cash, without interest ("Merger Consideration"). Additionally, at the effective time of the Merger, each outstanding option and restricted stock share or unit, whether or not then vested or exercisable, to purchase Tumbleweed Common Stock, will be deemed 100% vested and exercisable on the terms and conditions set forth in the Merger Agreement.  The proposed transaction is subject to customary closing conditions including regulatory and Tumbleweed stockholder approvals.

           The foregoing description of the Merger is not complete and is qualified in its entirety by reference to the Merger Agreement and the related agreements, which are filed as Exhibit 2.1 hereto and are incorporated herein by reference.
