NOTICE OF VARIATION

by

Wi-LAN Inc.

in respect of its

OFFER TO PURCHASE

all of the outstanding Common Shares of

MOSAID Technologies Incorporated

on the basis of an increased price of

$42.00 in cash per Common Share

On October 19, 2011, Wi-LAN Inc. (“WiLAN”), by notice delivered to Kingsdale Shareholder Services Inc. (the “Depositary and Information Agent”), varied its offer dated August 23, 2011 (the “Offer”), as amended by the notices of extension and variation dated September 28, 2011 and October 13, 2011 (together, the “Prior Notices”), to purchase, on the terms and subject to the conditions of the Offer, all of the issued and outstanding common shares (“MOSAID Shares”) of MOSAID Technologies Incorporated (“MOSAID”) (together with associated rights issued and outstanding under MOSAID’s Shareholder Rights Plan (“SRP Rights”)), other than any MOSAID Shares owned, directly or indirectly, by WiLAN and its affiliates and including MOSAID Shares that may become issued and outstanding after the date of the Offer but before the expiry time of the Offer upon the exercise of options issued under MOSAID’s Option Plan (“Options”) or other rights to acquire MOSAID Shares (other than SRP Rights) to, among other things, increase the price payable under the Offer to $42.00 in cash per MOSAID Share.

THE OFFER HAS BEEN AMENDED

TO INCREASE THE OFFER PRICE TO $42.00 IN CASH PER MOSAID SHARE.

The Offer, as extended and varied, will be open for acceptance until 5:00 p.m. (Eastern time) on November 1, 2011 (the “Expiry Time”), unless the Offer is further extended or withdrawn.

WiLAN’s increased Offer price of $42.00 per MOSAID Share represents approximately a 38.6% premium over the volume-weighted average price of $30.31 per MOSAID Share on the TSX over the 10 trading days ending on August 17, 2011, the last trading day prior to the announcement of WiLAN’s intention to make the Offer and approximately a 63.0% premium over that volume-weighted average price excluding MOSAID’s cash from its balance sheet on a dollar-for-dollar basis.

Holders of MOSAID Shares (each, a “Shareholder” and collectively, the “Shareholders”) who have validly deposited (and not withdrawn) their MOSAID Shares to the Offer need take no further action to accept the Offer; such Shareholders will automatically be entitled to receive under the Offer the increased price of $42.00 per MOSAID Share deposited.

Shareholders who wish to accept the Offer must properly complete and duly execute the letter of transmittal printed on YELLOW paper (the “Letter of Transmittal”) that accompanied WiLAN’s Offer to Purchase and Circular dated August 23, 2011 (the “Offer and Circular”) or a manually signed facsimile thereof and deposit it at or prior to the Expiry Time, together with certificate(s) representing their MOSAID Shares and all other required documents, with the Depositary and Information Agent at its office in Toronto, Ontario specified in the Letter of Transmittal in accordance with the instructions in the Letter of Transmittal.

Alternatively, Shareholders may: (a) accept the Offer by following the procedures for book-entry transfer of MOSAID Shares described under “Manner of Acceptance – Acceptance by Book-Entry Transfer” in Section 3 of the Offer to Purchase; or (b) accept the Offer where the certificate(s) representing the MOSAID Shares are not immediately available, the Shareholder cannot complete the procedure for book-entry transfer of the MOSAID Shares on a timely basis, or the certificate(s) and all other required documents cannot be delivered to the Depositary and Information Agent prior to the Expiry Time, by following the procedures for guaranteed delivery described under “Manner of Acceptance – Procedure for Guaranteed Delivery” in Section 3 of the Offer to Purchase using the notice of guaranteed delivery printed on PINK paper (the “Notice of Guaranteed Delivery”) that accompanied the Offer and Circular or a manually signed facsimile thereof.

Shareholders whose MOSAID Shares are registered in the name of an investment advisor, stockbroker, bank, trust company or other nominee should immediately contact that nominee for assistance if they wish to accept the Offer to take the necessary steps to be able to deposit such MOSAID Shares under the Offer. Intermediaries likely have established tendering cut-off times that are up to 48 hours prior to the Expiry Time. Shareholders must instruct their respective brokers or other intermediaries promptly if they wish to tender to the Offer.

Shareholders will not be required to pay any fee or commission if they accept the Offer by depositing their MOSAID Shares directly with the Depositary and Information Agent or if they make use of the facilities of a Dealer Manager or a member of the Soliciting Dealer Group to accept the Offer. However, a broker or nominee through whom a Shareholder owns MOSAID Shares may charge a fee to tender such MOSAID Shares. Shareholders should consult their brokers or nominees to determine whether any charges will apply.

Questions and requests for assistance may be directed to the Depositary and Information Agent or to Canaccord Genuity Corp. or CIBC World Markets Inc. (collectively, the “Dealer Managers”). Contact details for such persons may be found on the last page of this document. Additional copies of this Notice of Variation, the Prior Notices, the Offer and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained without charge on request from the Depositary and Information Agent or the Dealer Managers at their respective addresses shown on the last page of this document.

This Notice of Variation does not constitute an offer or a solicitation to any person in any jurisdiction in which any such offer or solicitation is unlawful. The Offer is not being made to, nor will deposits be accepted from, or on behalf of, securityholders in any jurisdiction in which the making or acceptance thereof would not be in compliance with the laws of such jurisdiction. However, WiLAN or its agents may, in its or their sole discretion, take such action as it or they may deem necessary to extend the Offer to securityholders in any such jurisdiction.

NOTICE TO NON-CANADIAN RESIDENTS

The Offer is being made for the securities of a Canadian issuer. The Offer and Circular are subject to, and have been prepared in accordance with, applicable disclosure requirements in Canada. Shareholders should be aware that such requirements are different from those in the United States and may differ from those in other jurisdictions. The Offer is generally not subject to U.S. tender offer rules provided by Rule 14d-1(c).

The enforcement by Shareholders of civil liabilities under United States federal securities Laws or those in other jurisdictions may be affected adversely by the fact that each of WiLAN and MOSAID are governed by the Laws of Canada, that the majority of the officers and directors of each of WiLAN and MOSAID reside in Canada, that the Depositary and Information Agent and some or all of the experts named in the Offer and Circular may be residents of jurisdictions of Canada and that all or a substantial portion of the assets of WiLAN, MOSAID and the other above-mentioned persons are located in Canada. You may not be able to sue WiLAN or its officers or directors in a Canadian court for violations of non-Canadian securities Laws. It may be difficult to compel WiLAN or its officers or directors to subject themselves to a U.S. or your local court’s judgment.

2

Shareholders in the United States should be aware that the disposition of MOSAID Shares by them as described in the Offer and Circular may have tax consequences both in the United States and in Canada. Such consequences may not be fully described in the Offer and Circular and such Shareholders are urged to consult their tax advisors. See “Principal Canadian Federal Income Tax Considerations” and “United States Federal Income Tax Considerations” in Sections 17 and 18 of the Circular, respectively.

Shareholders in the United States should be aware that WiLAN and its affiliates and any joint actors, directly or indirectly, may bid for or may make purchases of MOSAID Shares during the period of the Offer, as permitted by applicable Canadian laws or provincial laws or regulations.

THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY STATE OR OTHER SECURITIES REGULATORY AUTHORITY, NOR HAS THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION OR ANY STATE OR OTHER SECURITIES REGULATORY AUTHORITY PASSED UPON THE ACCURACY OR ADEQUACY OF THE OFFER AND CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

NOTICE TO HOLDERS OF MOSAID OPTIONS AND OTHER RIGHTS

The Offer is made only for MOSAID Shares and is not made for any Options or other rights (other than SRP Rights) to acquire MOSAID Shares. Any holder of Options or other rights (other than SRP Rights) to acquire MOSAID Shares who wishes to accept the Offer should, subject to and to the extent permitted by the terms of the Option Plan, the terms of any agreement governing such Options or other rights and applicable Law, exercise or convert such Options or other rights in order to obtain certificates representing MOSAID Shares and deposit the MOSAID Shares in accordance with the Offer. See Section 1 of the Offer to Purchase, the “Offer”. Any such exercise or conversion must be completed sufficiently in advance of the Expiry Time to assure the holder of such Options or other rights to acquire MOSAID Shares that the holder will have certificates representing the MOSAID Shares received on such exercise or conversion available for deposit prior to the Expiry Time, or in sufficient time to comply with the procedures described under “Manner of Acceptance – Procedure for Guaranteed Delivery” in Section 3 of the Offer to Purchase.

The tax consequences to holders of Options of exercising their Options are not described in either Section 17 of the Circular, “Principal Canadian Federal Income Tax Considerations” or in Section 18 of the Circular, “United States Federal Income Tax Considerations”. Holders of Options should consult their tax advisors for advice with respect to potential income tax consequences to them in connection with the decision to exercise or convert their Options.

NOTICE OF VARIATION

This Notice of Variation should be carefully read in conjunction with the Prior Notices and the Offer and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery.

October 20, 2011

TO:  THE SHAREHOLDERS OF MOSAID TECHNOLOGIES INCORPORATED

By notice delivered to the Depositary and Information Agent on October 19, 2011 and as set forth in this Notice of Variation, WiLAN has varied its Offer dated August 23, 2011, as amended by the Prior Notices, pursuant to which WiLAN is offering to purchase all of the issued and outstanding MOSAID Shares (together with associated SRP Rights), other than any MOSAID Shares owned, directly or indirectly, by WiLAN and its affiliates and including MOSAID Shares that may become issued and outstanding after the date of the Offer but before the expiry time of the Offer upon the exercise of Options or other rights to acquire MOSAID Shares (other than SRP Rights) upon the terms and subject to the conditions set forth in the Offer and Circular, the Prior Notices and this Notice of Variation, to, among other things, increase the price payable for the MOSAID Shares from $38.00 per MOSAID Share to $42.00 per MOSAID Share.

Except as otherwise set forth in this Notice of Variation, the terms and conditions previously set forth in the Offer and Circular, the Prior Notices, the Letter of Transmittal and the Notice of Guaranteed Delivery (the “Original Offer”) continue to be applicable in all respects and this Notice of Variation should be read in conjunction with the Original Offer.  Unless the context requires otherwise, terms not defined herein have the meanings set forth in the Original Offer.  Unless the context otherwise requires, all references to the “Offer”, the “Circular” and the “Offer to Purchase” in the Original Offer and this Notice of Variation mean the “Offer”, the “Circular” and the “Offer to Purchase”, as amended by the Prior Notices and this Notice of Variation.

1. Increase in Offer Price for MOSAID Shares

WiLAN has varied the Offer by increasing the price offered to Shareholders under the Offer to $42.00 in cash per MOSAID Share from $38.00 in cash per MOSAID Share.

Assuming that all of the conditions to the Offer are satisfied or waived, all Shareholders whose MOSAID Shares are validly deposited and taken up under the Offer, including Shareholders who have already deposited their MOSAID Shares under the Offer, without exception, will receive the increased price for any of their MOSAID Shares that are taken up under the Offer.  Shareholders who have validly deposited (and not withdrawn) their MOSAID Shares to the Offer need to do nothing further.

The increased Offer price of $42.00 is higher than the MOSAID shares have traded in the past 10 years. The revised Offer price represents:

· a premium of approximately 10.5% to WiLAN’s original Offer price of $38.00;

· a premium of approximately 32.2% to the closing price of the MOSAID Shares on August 17, 2011;

· a premium of approximately 38.6% to the volume weighted average trading price of the MOSAID Shares on the TSX for the 10 trading days ending on August 17, 2011; and

· a premium of approximately 63.0% to the volume weighted average trading price of the MOSAID Shares on the TSX for the 10 trading days ending on August 17, 2011 excluding MOSAID’s cash shown on its balance sheet on a dollar-for-dollar basis from price of the MOSAID Shares.

“WiLAN also granted an option to the Underwriters (the “Over-Allotment Option”), exercisable in whole or in part to purchase up to an additional $30,000,000 aggregate principal amount of Debentures on the same terms as the Debentures described above solely to cover over-allocations, if any, and for market stabilization purposes.  On September 9, 2011, the Underwriters exercised the Over-Allotment Option in full. On September 12, 2011, WiLAN completed the sale of the additional 30,000 Debentures for additional gross proceeds of $30.0 million. With the exercise of the Over-Allotment Option, WiLAN sold 230,000 Debentures pursuant to the Debenture Offering for total gross proceeds of $230.0 million and total net proceeds of $218.5 million. All of the net proceeds received by WiLAN through the Debenture Offering will be used to finance the cash payable under the Offer.”

The fourth paragraph in the section titled “Bought Deal Financing” is deleted in its entirety and replaced with the following:

“The Underwriters’ fee in respect of the Debentures is 5.0% of the gross proceeds of the Debenture Offering. 50% of the Underwriters’ fee was paid upon the closing of the Debenture Offering and 50% of the Underwriters’ fee will be payable upon the Take-Up.  If the Take-Up does not occur, the Underwriters’ fee will be reduced to the amount that has already been paid.”

The fifth paragraph in the section titled “Bought Deal Financing” is amended by deleting the last sentence in its entirety.

In addition, the “Glossary” is amended by deleting the definition of “Debenture Offering” and replacing it with the following:

““Debenture Offering” means the offering by WiLAN of $200,000,000 aggregate principal amount of Debentures, which offering closed on September 8, 2011, together with the offering by WiLAN of $30,000,000 aggregate principal amount of Debentures, pursuant to the exercise of the Over-Allotment Option, which offering closed on September 12, 2011;”

Revised Conditions of the Offer

The conditions of the Offer set forth in Section 4 of the Offer to Purchase, “Conditions of the Offer”, as amended by the Prior Notice dated September 28, 2011 to add conditions (t) and (u), are amended to delete conditions (t) and (u).

In addition, the “Glossary” is amended by deleting paragraph (k) in the definition of “Restricted Event” and replacing it with the following:

“(k) the taking of any action or authorizing, recommending, proposing or announcing the intention to take any action, with respect to any agreement, proposal, offer or understanding relating to any sale, license, lease, pledge or disposition or other dealing with any of the assets of MOSAID or any of its Subsidiaries or affiliates other than any such sale, license, lease, pledge or disposition or other dealing that is either in the ordinary course of MOSAID’s business, consistent with past practice, or that is between MOSAID and any wholly-owned Subsidiary of MOSAID;”

MOSAID Share Split

To reflect the increased Offer price, WiLAN has amended the sentence, “If the Stock Split is implemented prior to the Expiry Time, the Offer price of $38.00 per MOSAID Share will automatically be divided by two.”, contained in Section 9 of the Offer to Purchase, “Changes in Capitalization, Dividends, Distributions and Liens”, by replacing the dollar value “$38.00” with “$42.00”.
