Explanation of Responses:

 

(1)     A family trust of the reporting person received 50,000 shares of SONS stock in connection  with a redemption of shares in an exchange fund.  The shares were valued at $1.59 per share for the purpose of determining the number of shares distributable  in connection with the redemption.

(2)     Includes 545,451 shares held by a trust for the benefit of Mr. Mayersohn's family and minor children.  Mr. Mayersohn disclaims any beneficial interest in these 545,451 shares except to the extent of his pecuniary interests therein.

(3)     Includes 3,772 shares acquired under the SONS employee stock purchase plan in January, 2002 and 2,500 shares acquired under the SONS employee stock purchase plan in January, 2003. Includes shares of restricted stock which are subject to repurchase by the issuer if Mr. Mayersohn ceases to be employed by SONS.  The right of repurchase on the common stock lapses over time depending upon the purchase date of the restricted stock and the respective purchase agreements.
