David Bundy

Gary McGuire

Mr. McGuire was the vice president of Federal Sales for FVC's suite of desktop communications applications and headed the federal sales team.

Prior to FVC, Mr. Chavy was the engineering manager at CUseeMe where he managed the client core and GUI teams - teams responsible for the company's Click to Meet Express product which quickly became the company's leading revenue producer.

Alan Moskowitz

Mr. Moskowitz is a seasoned manager with both technical and sales experience in directing worldwide support staffs.
