(f) The Reporting Person is a citizen of the United States.
Item 3.	Source and Amount of Funds or Other Consideration
As described in Item 4 below, the Reporting Person acquired his shares of common stock of the Issuer by way of a share exchange transaction, with the consideration for the Reporting Person’s acquisition of shares of Issuer common stock being the Reporting Person’s shares of common stock of Biosource America, Inc., a Texas corporation (“Biosource”).

Item 4.	Purpose of Transaction
On March 30, 2006, the Issuer entered into a share exchange agreement (the “Share Exchange Agreement”) with Biosource and holders of shares of capital stock of Biosource (collectively the “Biosource Stockholders”). Pursuant to the Share Exchange Agreement, each Biosource Stockholder exchanged three shares of common stock of Biosource America for two

shares of common stock of the Issuer (the “Share Exchange”). The Share Exchange closed on March 31, 2006 and, as a result, the Issuer issued 40,000,000 shares of its common stock for the surrender of certificates in exchange therefor and Biosource became a subsidiary of the Issuer. Under the terms of the Share Exchange Agreement, the Issuer declared a three-for-two forward stock split in the form of a stock dividend payable on April 24, 2006 to holders of record on April 10, 2006. After the Share Exchange and three-for-two forward stock split, the Reporting Person beneficially owned 10,387,500 shares of the Issuer.

Beginning on February 12, 2008 and through May 6, 2008, the Reporting Person sold an aggregate of 3,103,756 shares for aggregate gross proceeds of $3,724,878.84. The information set forth in Item 5(c) below is herein incorporated by reference.

Except as described in Item 4, the Reporting Person does not have any plans or proposals that relate to or would result in: (i) the acquisition of additional securities of the Issuer, or the disposition of securities of the Issuer; (ii) any extraordinary corporate transaction; (iii) any sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (iv) any change in the present board of directors or management of the Issuer; (v) any material change in the present capitalization or dividend policy of the Issuer; (vi) any other material change in the Issuer’s business or corporate structure; (vii) any changes in the Issuer’s charter, bylaws or instruments corresponding thereto, or other actions which may impede the acquisition of control of the Issuer by any person; (viii) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (ix) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or (x) any action similar to any of those enumerated above.
