Item 5.   Interest in Securities of the Issuer.
          ------------------------------------

          Item 5 is hereby  amended by deleting  Item 5 in its  entirety  and by
substituting the following in lieu thereof:

          Based upon information set forth in the Company's  Quarterly Report on
Form 10-Q for the  quarterly  period  ended  March 31,  2006,  as filed with the
Securities and Exchange Commission on May 15, 2006, there were 14,976,633 Shares
issued and outstanding as of May 11, 2006.

          As of June 8, 2006, the Accounts held an aggregate of 723,684  Shares.
Douglass  Bermingham  possesses sole power to vote and direct the disposition of
all Shares held in the  Accounts.  Accordingly,  for the  purposes of Rule 13d-3
under  the  Securities  Exchange  Act of  1934,  as  amended  (the  "Act"),  Mr.
Bermingham is deemed to beneficially  own 723,684 Shares,  or 4.8% of the Shares
deemed issued and outstanding as of June 8, 2006.  Mr. Bermingham has engaged in
certain  discussions  with Larry Bursten,  holder of 50,000 Shares as of June 8,
2006,  with  respect  to the future of the  Company  and its  various  strategic
alternatives. As a result of such conversations,  Messrs. Bermingham and Bursten
(the  "Parties")  may be deemed to have formed a "group" for purposes of Section
13(d) of the Act, and the rules promulgated thereunder. Accordingly, each of the
Parties  may be deemed to be the  beneficial  owner of the  Shares  beneficially
owned by the other.  Mr. Bermingham expressly disclaims  beneficial ownership of

expressly  disclaims any assertion or presumption that the Parties  constitute a





"group."  The aggregate  number of Shares held by the Parties as of June 8, 2006
is 773,684, or 5.2% of the Shares deemed issued and outstanding as of that date.

transactions  in Shares,  or securities  convertible  into,  exercisable  for or
exchangeable  for  Shares,  by  Mr. Bermingham  or any  other  person  or entity
controlled  by him or any  person or entity  for  which he  possesses  voting or
investment  control  over the  securities  thereof,  were the  purchase of 7,500
Shares on May 19, 2006,  at a price of  $1.361 per Share,  and the sale of 7,250
Shares  on May 31, 2006,  at a price of $1.578 (each of which was effected in an
ordinary brokerage transaction).
