On September 1, 2006, Arch Management Services Inc. (the "Company") and Gallant
Energy International Inc. ("Gallant") entered into a Purchase Agreement,
pursuant to which Gallant sold the Company its interest in a joint venture (the
"Venture") it formed with certain Chinese entities to develop facilities for the
production of ethanol fuel in the People's Republic of China, as reported on a
Form 8-K filed with the U.S. Securities and Exchange Commission on September 18,
2006.

The complexities of integrating the Venture's operations into the Company has
caused the Company to experience delays in the preparation of its Report on Form
10-QSB. The Company intends to file the Form 10-QSB in a timely manner within
the extension time period provided under Rule 12(b)(25) promulgated under the
Securities Exchange Act of 1934, as amended.
