UNAUDITED PRO FORMA FINANCIAL INFORMATION

On June 5, 2009 (the “Effective Date”), Human BioSystems, a California corporation (“HBS”), Human BioSystems Acquisition Company, a Nevada corporation (the “Subsidiary”), and San West, Inc., a Nevada corporation (“San West”) closed their Plan and Agreement of Triangular Merger (the “Plan of Merger”).  In accordance with the Plan of Merger, San West became a wholly-owned subsidiary of HBS through a merger with the Subsidiary.  The San West Stockholders received restricted HBS Common Stock at the rate of 3.16165 shares for each of their 4,136,836 shares issued and outstanding.  As a result, HBS issued 13,079,264 restricted shares in exchange for 100 percent of the outstanding capital stock of San West.  In addition, 817,454 restricted shares of the HBS Common Stock were issued to Dutchess Advisors, LLC as a finder’s fee.  HBS had 4,201,934 shares outsta nding as of the Effective Date of the merger.  In total 18,098,652 shares are outstanding following the Effective Date of Merger.

HBS intends to carry on the business of San West as our sole line of business.  HBS has relocated its principal executive offices to 10350 Mission Gorge Road, Santee, California 92069, and has a telephone number of (714) 724-3355.

The Merger is being accounted for as a “reverse merger”.  San West is deemed to be the acquirer in the reverse merger.  Consequently, the assets and liabilities and retained deficit of San West prior to the Merger will be reflected in the financial statements.  The following unaudited financial information has been developed by application of pro forma adjustments to the historical financial statements of San West, Inc. appearing elsewhere in this Current Report. The unaudited pro forma information gives effect to the Merger which has been assumed to have occurred on March 31, 2009 for purposes of the pro forma balance sheet and as of January 1, 2008 for purposes of the statement of operations for the year ended December 31, 2008 and the three months ended March 31, 2009.

The unaudited pro forma adjustments are based upon available information and certain assumptions, as described in the accompanying notes that we believe are reasonable under the circumstances. The unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what the results of operations or financial position of San West, Inc. would have been had the transactions described above actually occurred on the dates indicated, nor do they purport to project the financial condition of San West, Inc. for any future period or as of any future date. The unaudited pro forma financial information should be read in conjunction with the San West, Inc. financial statements and notes thereto included elsewhere in this Current Report.

The summarized assets and liabilities of the purchased company (Human BioSystems) on June 5, 2009 (“Effective Date”) were as follows:
