At 5 P.M. (Delaware Time) on February 17, 2006 (the "Effective Time"), the one-for-fifty (1 for 50) reverse stock split of the common stock of Avitar, Inc. (the "Corporation") became effective. As previously announced, at the Effective Time each fifty shares of the Corporation's common stock, par value $.01 per share , issued and outstanding immediately prior to the Effective Time automatically, without further action on the part of the Corporation or its stockholders, combined into and became one share of fully paid and nonassessable common stock. No fractional shares will be issued in connection with the reverse stock split. Stockholders who otherwise would be entitled to receive fractional shares will be entitled, upon surrender to the exchange agent of certificate(s) representing such shares, to one full share in lieu of any such fractional share. Our transfer agent, Continental Stock Transfer & Trust Company, is acting as exchange agent for purposes of implementing the exchange of stock certificates, and is referred to as the "exchange agent." As soon as practicable after the Effective Time, a letter of transmittal is being sent to stockholders of record as of the Effective Time for purposes of surrendering to the exchange agent certificates representing pre-reverse stock split shares in exchange for certificates representing post-reverse stock split shares in accordance with the procedures set forth in the letter of transmittal. No new certificates will be issued to a stockholder until such stockholder has surrendered such stockholder's outstanding certificate(s), together with the properly completed and executed letter of transmittal, to the exchange agent. From and after the Effective Time, any certificates formerly representing pre- reverse stock split shares which are submitted for transfer, whether pursuant to a sale, other disposition or otherwise, will be exchanged for certificates representing post-reverse stock split shares. Stockholders who do not have stock certificates for surrender and exchange will have their accounts automatically adjusted in order to reflect the number of shares of common stock they hold as a consequence of the reverse stock split.
