follows:

operated and such business is now conducted. The authorized capital stock of
BioMed consists of 40,000,000 shares of Common Stock, par value $.001 per share,

share of Preferred Stock, par value $.001 per share, of which no shares have
been issued. BioMed is duly licensed or qualified and in good standing as a
foreign corporation where the character of the properties owned by BioMed or the
nature of the business transacted by it make such license or qualification
necessary.

         3.2 THE BIOMED SHARES. The BioMed Shares to be issued to the Sure
Shareholders have been or will have been duly authorized by all necessary
corporate and shareholder actions and, when so issued in accordance with the

sheet of BioMed as of December 31, 2001, and statements of operations for the

delivered to Sure were compiled but were not prepared in accordance with
generally accepted accounting principles applied on a consistent basis with
prior periods. However, such compiled financial statements fairly represent the
financial position of BioMed as at such dates and the results of its operations
for the periods then ended.
