COMMENT 2:        We note your  response to comment 2.  Please  advise us of the
                  revisions you intend to make in all future  filings to clarify
                  the terms of your  outstanding  stock  options and warrants in
                  accordance  with  paragraph  A240 or SFAS 123(R).  It does not
                  appear that the  requested  disclosures  were  provided in the

RESPONSE:         THE COMPANY  ACKNOWLEDGES THE COMMISSION'S  COMMENT 2. CERTAIN
                  DISCLOSURES  REQUIRED  BY SFAS  123(R),  PARAGRAPH  A240  WERE

                  QUARTER ENDED MARCH 31, 2006 BECAUSE THEY WERE NOT  APPLICABLE
                  OR  WERE  CONSIDERED  IMMATERIAL  OR  NON-SUBSTANTIVE.  FUTURE
                  FILINGS  WILL BE REVISED TO INCLUDE  AND  CLARIFY THE TERMS OF
                  THE  COMPANY'S  OUTSTANDING  STOCK  OPTIONS  AND  WARRANTS  IN
                  ACCORDANCE WITH PARAGRAPH A240 OF SFAS 123(R) AS FOLLOWS:

                  o     THE COMPANY WILL INCLUDE A MORE DETAILED  DESCRIPTION OF
                        THE  SHARE-BASED  PAYMENT  ARRANGEMENTS,  INCLUDING  THE
                        GENERAL TERMS OF THE ARRANGEMENTS, SUCH AS THE REQUISITE
                        SERVICE PERIOD AND ANY OTHER SUBSTANTIVE CONDITIONS, THE
                        MAXIMUM  CONTRACTUAL  TERM OF EQUITY  SHARE  OPTIONS AND
                        WARRANTS, AND THE NUMBER OF SHARES AUTHORIZED FOR AWARDS
                        OF EQUITY SHARE OPTIONS AND  WARRANTS.  THE COMPANY WILL
                        ALSO DISCLOSE THE METHOD USED FOR MEASURING COMPENSATION
                        COST  FROM   SHARE-BASED   PAYMENT   ARRANGEMENTS   WITH
                        EMPLOYEES.

                  o     THE COMPANY  WILL INCLUDE THE  EXPECTED  TERM,  EXPECTED
                        VOLATILITY,  EXPECTED DIVIDENDS, AND RISK-FREE RATES FOR
                        SHARE OPTIONS.

                  o     THE  COMPANY  WILL ALSO USE A MORE  DETAILED  DISCLOSURE
                        CHECKLIST  FOR ALL FUTURE  FILINGS TO ENABLE THE COMPANY
                        TO  INCORPORATE  ALL  REQUIRED  DISCLOSURES  UNDER  SFAS
                        123(R),  ALTHOUGH THE AFFECT ON THE FINANCIAL STATEMENTS
                        IS CONSIDERED IMMATERIAL.
