Under the provisions of Securities and Exchange Commission Staff Bulletin
No. 64 ("SAB" No. 64), common stock and common stock equivalents issued by
the company within one year or in contemplation of the Company's offering
are treated as if they were outstanding for all periods presented prior to
the Company's IPO. After the IPO is effective, the determination of common
stock and equivalents has been determined on basis consistent with APB
Opinion No. 15, which states "outstanding options and warrants should be
included in the EPS computation only if they have a dilutive effect."

This calculation is submitted in accordance with Securities Exchange Act of
1934 Release No. 9083 although not required by footnote 2 of paragraph 14
of APB Opinion No. 15 because it results in dilution of less than 3%.
