INTRODUCTION

        This Rule 13e-3 Transaction Statement (the "Transaction Statement") is being filed with the Securities and Exchange Commission (the "SEC") pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), by Forgent Networks, Inc. d/b/a Asure Software, a Delaware corporation ("Forgent" or the "Company").

        The Company proposes to hold a special meeting of its stockholders to consider two separate proposals to amend the Company's Restated Certificate of Incorporation to effect a reverse/forward stock split (the "Reverse/Forward Stock Split") of the Company's common stock, par value $.01 per share (the "Common Stock"). The Reverse/Forward Stock Split consists of a 1-to-750 reverse stock split (the "Reverse Stock Split") whereby stockholders owning less than 750 shares of Common Stock before the Reverse Stock Split would have such shares cancelled and converted into the right to receive the cash consideration set forth herein. After the Reverse Stock Split is completed, it will be followed immediately by a 750-to-1 forward stock split (the "Forward Stock Split") whereby stockholders owning 750 or more shares of Common Stock before the Reverse Stock Split would own the same number of shares of Common Stock after the Forward Stock Split.
