OTTAWA, Canada - October 19, 2011 - Wi-LAN Inc. (“WiLAN” or the “Company”) (TSX:WIN) (NASD:WILN) today announced that it has increased its fully funded all cash Offer to acquire MOSAID Technologies Incorporated (“MOSAID”) by 11% to $42.00 per MOSAID Common Share (“Share”). The Offer will remain open until 5:00 pm Eastern time on November 1, 2011 (the “Revised Offer”). WiLAN has no intention to further revise or extend its Revised Offer.

The Revised Offer is not subject to any financing contingencies. WiLAN will finance the Revised Offer through cash on hand and previously arranged financing.

The Revised Offer is higher than MOSAID Shares have traded in more than 10 years prior to the announcement of WiLAN’s intention to make the Offer. The Revised Offer price of $42.00 per MOSAID Share represents an 11% premium to the original Offer price and a 38.6% premium to the volume weighted average trading price of the MOSAID Shares on the TSX for the period ending on August 17, 2011, the last trading day prior to the announcement of the initial Offer. Excluding MOSAID’s cash from its balance sheet on a dollar-for-dollar basis from MOSAID’s Share price, the Revised Offer represents a premium of 63.0%.

The all cash, fully funded Revised Offer provides immediate and certain value for MOSAID shareholders. It removes exposure to business uncertainty and ongoing operational and market risk, particularly in light of the continued volatility in global financial markets.

“We continue to believe that combining our two Ottawa-based firms is a unique and exciting opportunity to create a global IP licensing powerhouse that combines the talent of two great teams. We expect to retain the vast majority of MOSAID staff upon successful completion of this transaction,” said Jim Skippen, Chairman and CEO. “Acquiring MOSAID fits perfectly within our long-term growth strategy and our commitment to increasing shareholder value. The acquisition of MOSAID remains accretive to WiLAN’s adjusted earnings per share in fiscal 2012 and has the unanimous support of the WiLAN Board.”

Added Skippen, “It has been more than two months since WiLAN announced its intention to acquire MOSAID. We believe it to be a compelling and full offer, particularly in light of current market conditions.”
