Reference is hereby made to Items 5-9 and 11 of page 2 of this Schedule, which Items are incorporated by reference herein.
 
Under the definition of “beneficial ownership” in Rule 13d-3 under the Securities Exchange Act of 1934, it is also possible that the individual directors, executive officers, and/or shareholders of Wentworth might be deemed the “beneficial owners” of some or all of the securities to which this Schedule relates in that they might be deemed to share the power to direct the voting or disposition of such securities.  Neither the filing of this Schedule nor any of its contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner of any of the securities to which this Schedule relates, and such beneficial ownership is expressly disclaimed.
 
The calculation of percentage of beneficial ownership in item 11 of page 2 was derived from the Issuer’s Form 10-Q filed with the Securities and Exchange Commission on February 8, 2008, in which the Issuer stated that the number of shares of its Common Stock outstanding as of January 31, 2008 was 18,961,663.
