WHEREAS, the Subsidiary is a wholly-owned subsidiary of Human BioSystems; and

WHEREAS, San West desires to merge (the “Merger”), subject to the approval of its stocholders (the “San West Stockholders”) with and into the Subsidiary; and

NOW, THEREFORE, in consideration of the foregoing and the following mutual covenants and agreements, the parties agree as follows:

Plan Adopted. A plan of merger whereby San West merges with and into the Subsidiary (this “Plan of Merger”), pursuant to the provisions of Chapter 92A of the Nevada Revised Statutes (the “NRS”), and Section 368(a)(2)(D) of the Internal Revenue Code of 1986, as amended, is adopted as follows:

(a)

San West shall be merged with and into the Subsidiary, to exist and be governed by the laws of the State of Nevada.

(b)

The Subsidiary shall be the surviving corporation (the “Surviving Corporation”) and its name shall be changed to San West, Inc. The Surviving Corporation will continue to be a wholly-owned subsidiary of Human BioSystems.

(c)

When this Plan of Merger shall become effective, the separate existence of San West shall cease and the Surviving Corporation shall succeed, without other transfer, to all the rights and properties of San West and shall be subject to all the debts and liabilities of such corporation in the same manner as if the Surviving Corporation had itself incurred them. All rights of creditors and all liens upon the property of each constituent entity shall be preserved unimpaired, limited in lien to the property affected by such liens immediately prior to the Merger.

(d)

The Surviving Corporation will be responsible for the payment of all fees and franchise taxes of the constituent entities payable to the States of Nevada and California, if any.

(e)

The Surviving Corporation will carry on business with the assets of San West, as well as the assets of the Subsidiary.

(f)

The Surviving Corporation will be responsible for the payment of the fair value of shares, if any, required under Chapter 92A of the NRS.

(g)

The San West Stockholders will surrender all of their shares of the San West Common Stock in the manner hereinafter set forth.

(h)

In exchange for the shares of the San West Common Stock surrendered by the San West Stockholders, Human BioSystems will issue and transfer to them on the basis hereinafter set forth, shares of the Human BioSystems Common Stock.

(i)

A copy of this Plan of Merger will be furnished by the Surviving Corporation, on request and without cost, to any stockholder of any constituent corporation.

(j)

The authorized capital stock of the Subsidiary is 400,000,000 shares of common stock, par value $0.001 per share (the “Subsidiary Common Stock”), of which one share is issued and outstanding, and 50,000,000 shares of preferred stock, par value $0.001 per share, of which none are issued or outstanding.

(k)

The authorized capital stock of San West is 25,000,000 shares of common stock, par value $0.001 per share, of which 4,136,836 shares are issued and outstanding held by 33 San West Stockholders, all of whom are “accredited investors” as defined in the Securities Act of 1933, as amended (the “Securities Act”).

Effective Date. The effective date of the Merger (the “Effective Date”) shall be the date of the filing of Articles of Merger for the Subsidiary and San West in the State of Nevada.

Submission to Stockholders. This Plan of Merger shall be submitted for approval separately to the San West Stockholders and to Human BioSystems, the sole stockholder of the Subsidiary, in the manner provided by the laws of the State of Nevada.

Manner of Exchange. On the Effective Date, the San West Stockholders shall surrender their stock certificates representing all of the issued and outstanding shares of the San West Common Stock to the Subsidiary in exchange for certificates representing the shares of the Human BioSystems Common Stock to which they are entitled. In exchange, the Subsidiary shall receive all of the issued and outstanding shares of the San West Common Stock held by the San West Stockholders. Following the receipt of the shares of the San West Common Stock by the Subsidiary, the shares of the San West Common Stock shall be cancelled. The one share of the Subsidiary Common Stock shall remain issued and outstanding.

Basis of Exchange. The San West Stockholders currently own 4,136,836 shares of the San West Common Stock, which shares constitute all of the issued and outstanding shares of the capital stock of San West. As a result of the Merger, the San West Stockholders shall be entitled to receive, in exchange for all of their San West Common Stock, 13,079,264 shares of the Human BioSystems Common Stock on the basis of 3.16 shares of the Human BioSystems Common Stock for each share of the San West Common Stock held by each of the San West Stockholders. Any fractional number of shares to be received shall be rounded up to the nearest whole number. Following the Effective Date, Human BioSystems shall have 16,349,080 shares of the Human BioSystems Common Stock issued and outstanding, owned as follows: (a) 2,452,362 shares owned by the Human BioSystems Stockholders; (b) 13,079,264 shares owned by the San West Stockholders; and (c) 817,454 shares owned by Dutchess Advisors LLC as a finders fee. Provided, however, notwithstanding anything herein contained to the contrary, if there is any change in the issued and outstanding shares of either Human BioSystems or San West as of the Effective Date, the number of shares to be issued hereunder shall be adjusted accordingly, so that the San West Stockholders will own following the Effective Date at least 80 percent of the issued and outstanding shares of the Human BioSystems Common Stock and the Human BioSystems Stockholders will own approximately 15 percent of the issued and outstanding shares of the Human BioSystems Common Stock following the Effective Date after the payment of the finders fee herein described. Provided, further, however, between the date of this Agreement and April 17, 2009, Human BioSystems may issue shares of the Human BioSystems Common Stock to raise the $26,000 payment to be made by San West as described in Paragraph 12(b) hereof, and in such event, the issuance of such shares shall be deemed to have occurred after the Effective Date so as to result in a dilution of all stockholders of Human BioSystems following the Effective Date, including, but not limited to the Human BioSystems Stockholders, the San West Stockholders and Dutchess Advisors LLC. In the event of the issuance of such shares of the Human BioSystems Common Stock as described in this paragraph, the provisions of Paragraph 12(b) shall be deemed null and void.

Restricted Shares. All shares of the Human BioSystems Common Stock to be received by the San West Stockholders and Dutchess Advisors LLC hereunder shall be restricted in their resale as provided in the

Securities Act, and shall contain a legend as required by Rule 144 promulgated under the Securities Act (“Rule 144”) which shall read as follows:

THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND NEITHER SUCH SHARES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, PLEDGED, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS A REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

The restricted nature of such shares shall not be taken into account or any quoted price of the shares on the Effective Date. Upon receipt of the Human BioSystems Common Stock, each San West Stockholder shall execute a Subscription Agreement in the form attached hereto as Attachment A. In that regard, the San West Stockholders shall acknowledge that Human BioSystems does not have any obligation to register for resale pursuant to the Securities Act, the shares of the Human BioSystems Common Stock to be received by them hereunder.

(c)

Consents in Lieu of Meeting. Any action that is required or permitted to be taken by the stockholders of the Company at any annual or special meeting of stockholders may be taken without a meeting if, before or after the action, a written consent thereto is signed by stockholders holding at least a majority of the voting power, except that if a different proportion of voting power is required for such an action at a meeting, then that

2.10.

Approval or Ratification of Acts or Contracts by Stockholders. The Board of Directors in its discretion may submit any act or contract for approval or ratification at any annual meeting of the stockholders, or at any special meeting of the stockholders called for the purpose of considering any such act or contract, and any act or contract that shall be approved or be ratified by the vote of the stockholders holding a majority of the issued and outstanding shares of stock of the Company entitled to vote and present in person or by proxy at such meeting (provided that a quorum is present), shall be as valid and as binding upon the Company and upon all the stockholders as if it has been approved or ratified by every stockholder of the Company.

2.11.

Inspectors of Election. The Company shall, in advance of any meeting of stockholders, appoint one or more inspectors of election, who may be employees of the Company, to act at the meeting or any adjournment thereof and to make a written report thereof.

Each inspector, before entering upon the discharge of his duties, shall take and sign an oath to execute faithfully the duties of inspector with strict impartiality and according to the best of his ability.

The inspector or inspectors so appointed or designated shall: (a) ascertain the number of shares of capital stock of the Company outstanding and the voting power of each such share; (b) determine the shares of capital stock of the Company represented at the meeting and the validity of proxies and ballots; (c) count all votes and ballots; (d) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors; and (e) certify their determination of the number of shares of the capital stock of the Company represented at the meeting and such inspectors’ count of all votes and ballots. Such certification and report shall specify such other information as may be required by law. In determining the validity and counting of proxies and ballots cast at any meeting of stockholders of the Company, the inspectors may consider such information as is permitted by applicable law. No person who is a candidate for an office at an election may serve as an inspector at such election.
