The complaint charges that Medis and certain of its present officers and senior management violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 by issuing materially false and misleading statements about certain "Commercial Sales" it claimed to have made to Microsoft.

The Complaint alleges that on April 13, 2007 the Company issued a press release announcing that it has begun "commercial sales" of its 24/7 fuel cell Power Packs to Microsoft and that the first shipment of Power Packs were made that day. This announcement caused the Company's stock to dramatically rise on April 13, 2007. Company CEO and Chairman Robert K. Lifton stated the moment was "historic." Later that day, the Company issued additional information about the Microsoft deal through its business development manager Andrew Udis, as reported by the publication Inside Greentech. Mr. Udis indicated that the products were "branded" by Microsoft, that the products would be sold around the world by Microsoft, and that the ultimate unit commitment was expected to be in the "millions." On April 17, 2007, after market close, it was reported by certain media outlets that according to a Microsoft spokesperson, Microsoft only purchased a "small amount" of Medis' products, the products were not Microsoft branded, that Microsoft had no intention to sell them to consumers but rather distribute them free at an upcoming event. Nor did Microsoft have any plans for development of the product. The Complaint alleges that these subsequent adverse disclosures concerning Medis' purported deal with Microsoft caused the Company's stock to fall.
