Item 5

5.1 Full Description of Material Change

Diversinet has completed the sale of its business pursuant to an asset purchase agreement (“Agreement”) with certain subsidiaries of IMS Health Incorporated (“IMS Health”).

Under the Agreement, IMS Health has purchased substantially all of the intellectual property, software, customer contracts and certain other assets of Diversinet for $3,500,000. An amount equal to one-half of the sale proceeds has been deposited with an independent escrow agent to be available to satisfy indemnity claims by IMS Health, if any, made prior to the proposed winding-up described below. Certain employees of Diversinet have accepted employment by IMS Health. On September 11, 2013, at the annual and special meeting of shareholders (“AGM”), Diversinet shareholders approved the sale transaction.

Furthermore, at the AGM, Diversinet shareholders approved a Plan of Liquidation and Distribution to take all necessary steps to effect the voluntary winding up of the Company pursuant to the Business Corporations Act (Ontario). This involves the appointment of a liquidator, Duff & Phelps Canada Restructuring Inc, effective on or about September 16, 2013 to discontinue the business of the Company and to satisfy all claims and obligations and to distribute to shareholders, on a pro rata basis, the remaining funds and assets of the Company. To the extent permitted by the OTCQB, the liquidator intends to have the common shares cease trading approximately 30 days after appointment.

A one time distribution to shareholders is not expected before early 2014. While there is no guarantee as to the amount of the shareholder distribution, Diversinet currently expects to distribute a per share amount in the range of $0.05 to $0.065 based on recent estimates of anticipated claims and obligations to be settled.
