Wi-LAN Signs Definitive Agreement to Acquire Tri-Vision

Merger will create Canadian pure play intellectual property giant

OTTAWA/TORONTO, Canada – May 11, 2007 – Wi-LAN Inc. (“Wi-LAN”) (TSX: WIN) and Tri-Vision International (“Tri-Vision”) (TSX: TVL) today announced they have signed a definitive acquisition agreement whereby Wi-LAN will acquire Tri-Vision, consistent with the letter of intent that was announced on March 27, 2007.

Once completed, the merger will create a Canadian pure play intellectual property giant. In addition to Wi-LAN’s already strong intellectual property portfolio in the wireless and telecom worlds, the combined company will have access to the high-growth V-chip market, the only solution to parental controls mandated by the U.S. Federal Communications Commission.

“I believe this is a great fit for Wi-LAN and further accelerates our growth strategy,” said Jim Skippen, Wi-LAN President & CEO. “Given the significant synergies with our potential licensees, it is a definite win-win for both companies. Many of the major companies who require a V-chip license are also targets for Wi-LAN’s existing portfolio.  In addition to providing strong future cash flows from existing licensees, it will expand our war chest to approximately $100 million to pursue other acquisition opportunities and to handle multiple litigations.”
 
“We believe this is an outstanding transaction for our shareholders,” added Tim Collings, Chairman of Tri-Vision and inventor of the V-chip. “We have always been confident in the strength of our V-chip technology. We are particularly excited about the opportunities this partnership represents to benefit from Wi-LAN’s licensing experience and litigation resources to help us enforce our patent rights, especially in the huge U.S. market. We look forward to working with their team to ensure a rapid and seamless transition.”

The boards of directors of both companies have unanimously approved the transaction. The board of directors of Tri-Vision, having received the recommendation of a special committee of independent directors formed to consider the transaction, is recommending that Tri-Vision shareholders vote in favour of the transaction. Acumen Capital Finance Partners Limited has provided the Tri-Vision board of directors with a formal written opinion stating that the transaction is fair, from a financial point of view, to the holders of Tri-Vision common shares. Senior officers and directors of Tri-Vision holding over 24% of Tri-Vision's outstanding common shares have agreed to vote in favour of the transaction and have signed a lock-up agreement.

Summary of the Transaction

Pursuant to the acquisition agreement, each Tri-Vision common share will be exchanged for a fraction of a Wi-LAN common share, determined by dividing $1.72 by the volume weighted average trading price of the Wi-LAN common shares on the TSX for 10 randomly selected days within the 20 trading days preceding closing of the transaction, provided that the exchange ratio will not exceed .2920 or be less than .2642 common shares of Wi-LAN for each common share of Tri-Vision.

Under the agreement, Tri-Vision will become a wholly-owned subsidiary of Wi-LAN. The agreement provides for the payment of termination fees by Tri-Vision and Wi-LAN in certain circumstances.  It is a condition of the completion of the transaction that Tri-Vision shall have acquired the V-chip patents, certain rights of which are currently licensed to Tri-Vision, from a company controlled by Tri-Vision Chairman, Tim Collings. Subject to regulatory approval and completion of the Wi-LAN merger transaction, Tri-Vision has agreed to issue 1,077,693 common shares in consideration for the transfer of these patents.

The transaction is subject to regulatory approvals and the approval by at least two-thirds of the votes cast at a meeting of Tri-Vision shareholders as a well as a majority of the votes cast at such meeting by disinterested shareholders. The transaction is expected to be completed by late June 2007.
