Item 4. Purpose of Transaction

      Desert Rock,  the Derek J. Stevens  Trust and the Gregory J. Stevens Trust
acquired  the shares in order to invest in the  Issuer.  The  Reporting  Persons
intend to review from time to time both the  Issuer's  business  affairs and the
business affairs and financial position of Desert Rock. Based on such evaluation
and review,  and subject to applicable  law and  regulation  and depending  upon
certain factors,  including without limitation, the financial performance of the
Issuer,  the Reporting  Persons may consider from time to time various strategic
alternatives.  Such strategic  alternatives may include, among other things, (i)
the acquisition of additional  shares of Common Stock or other securities of the
Issuer through open market  purchases or otherwise,  (ii) the sale of any number
of



shares of Common Stock or other securities of the Issuer through the open market
or  otherwise,  (iii)  extraordinary  corporate  transactions,  (iv) a  sale  or
transfer  of  a  material  amount  of  assets  of  the  Issuer  or  any  of  its
subsidiaries,  or (v) any other of the matters  described in clauses (a) through
(j) of Item 4 of Schedule 13D.

      As part of the Reporting  Persons'  ongoing review of their  investment in
the Common Stock of the Issuer,  each and/or all of the  Reporting  Persons will
from time to time hold talks or  discussions  with and respond to inquiries from
various parties, including, without limitation, the Issuer's Board of Directors,
management or representatives,  other shareholders and other persons or entities
regarding the Issuer's affairs and strategic alternatives.

Item 5. Interest in Securities of the Issuer.

      Based  upon the  Issuer's  Quarterly  Report on Form 10-Q for the  quarter
ended June 30, 2006, there were 12,463,755 shares of Common Stock outstanding as

beneficially  owned by Desert Rock represent  approximately  5.01% of the Common
