|--------------------|-------------------------------------------------------------------------------|

In      February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid      Financial Instruments - an amendment of FASB Statements No. 133 and 140,” to      simplify and make more consistent the accounting for certain financial      instruments. Specifically, SFAS No. 155 amends SFAS No. 133, Accounting for      Derivative Instruments and Hedging Activities, to permit fair value      remeasurement for any hybrid financial instrument with an embedded derivative      that otherwise would require bifurcation, provided that the whole instrument      is      accounted for on a fair value basis. SFAS No. 155 amends SFAS No. 140,      Accounting for the Impairment or Disposal of Long-Lived Assets, to allow a      qualifying special-purpose entity (SPE) to hold a derivative financial      instrument that pertains to a beneficial interest other than another derivative      financial instrument. SFAS No. 155 applies to all financial instruments acquired      or issued after the beginning of an entity’s first fiscal year that begins after      September 15, 2006, with earlier application allowed. The      Company does not expect that the adoption of SFAS No. 155 will have a      significant impact on the consolidated results of operations or financial      position of the Company.

**Item      1. Legal Proceedings.**

*Michael      Powell*.      In      August, 2006, Michael Powell commenced an action against certain defendants,      including us and certain of our officers, in the Ontario Superior Court of      Justice, claiming compensatory damages, special and punitive damages and various      forms of injunctive and declaratory relief for breach of contract and various      business torts. We believe the claims against us are frivolous and completely      without merit. We are not a party to any agreement with the plaintiff. Much      of      the requested relief relates to the plaintiff’s position and ownership interest      in and accounting for the expenses of an entity in which Generex has no      interest. We have not used any intellectual property or information owned by      the      other entity. All intellectual property, information and business claimed to      be      owned or conducted by the entity in which the plaintiff claims an interest      are      completely unrelated to any product or technology we are currently developing      or      intend to develop. Therefore, even if the court were to award some declaratory      or injunctive relief, we would not be affected. We are defending this action      vigorously. We are not able to predict the ultimate outcome of this legal      proceeding at the present time or to estimate an amount or range of potential      loss, if any, from this legal proceeding.
