The following, therefore, we confirm, are responses addressing only the Staff's comments in the SEC Letter. We also confirm that the comments of Staff are in ITALICS below while the Company's responses follow in BOLD. As a preliminary statement we thank both you and the remaining Staff very much for the opportunity of working with you in connection with this matter. Staff Comment: IT DOES NOT APPEAR THAT YOUR MANAGEMENT HAS PERFORMED ITS ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING AS OF DECEMBER 31, 2007. SINCE YOU WERE REQUIRED TO FILE OR FILED AN ANNUAL REPORT FOR THE PRIOR FISCAL YEAR, IT APPEARS YOU ARE REQUIRED TO REPORT ON YOUR MANAGEMENT'S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING. Page 2 IF YOUR MANAGEMENT HAS NOT YET PERFORMED ITS ASSESSMENT, WE ASK THAT YOU COMPLETE YOUR EVALUATION AND AMEND YOUR FILING WITHIN 30 CALENDAR DAYS TO PROVIDE THE REQUIRED MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING. Response: WE THANK THE STAFF FOR ITS COMMENT IN THIS REGARD AND WE HEREBY CONFIRM, ON BEHALF OF THE COMPANY, THAT THE COMPANY'S MANAGEMENT DID, IN FACT, PERFORM AN ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING AS OF DECEMBER 31, 2007, BUT THE COMPANY INADVERTENTLY FAILED TO REPORT ON MANAGEMENT'S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING IN THE COMPANY'S ANNUAL REPORT ON FORM 10-KSB AS FILED WITH THE SEC ON APRIL 11, 2008. AS SUCH, THE COMPANY HAS PREPARED AND FILED AN AMENDED ANNUAL REPORT ON FORM 10-KSB IN ORDER TO PROVIDE THE REQUIRED REPORT. Staff Comment: IN ADDITION, PLEASE CONSIDER WHETHER MANAGEMENT'S FAILURE TO PERFORM OR COMPLETE ITS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING IMPACTS ITS CONCLUSIONS REGARDING THE EFFECTIVENESS OF YOUR DISCLOSURE CONTROLS AND PROCEDURES AS OF THE END OF THE FISCAL YEAR COVERED BY THE REPORT AND REVISE YOUR DISCLOSURE AS APPROPRIATE. Response: WE THANK THE STAFF FOR ITS COMMENT IN THIS REGARD AND WE HEREBY CONFIRM, ON BEHALF OF THE COMPANY, THAT THE COMPANY HAS PROVIDED DISCLOSURE IN ITS AMENDED 10-KSB AS FILED WITH THE SEC TO INDICATE THAT MANAGEMENT HAS CONCLUDED THAT THE COMPANY'S DISCLOSURE CONTROLS AND PROCEDURES WERE NOT EFFECTIVE IN THAT ALTHOUGH MANAGEMENT PERFORMED AN ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING FOR THE YEAR ENDED DECEMBER 31, 2007, THE COMPANY INADVERTENTLY FAILED TO REPORT ON MANAGEMENT'S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING IN ITS ANNUAL REPORT ON FORM 10-KSB AS FILED WITH THE SEC ON APRIL 11, 2008.
