       AGREEMENT AND PLAN OF MERGER dated as of April 16, 2001 (the "Agreement"), by and among OPHIDIAN PHARMACEUTICALS, INC., a Delaware corporation ("ACQUIROR"), OPHIDIAN HOLDINGS, INC., a Delaware corporation and wholly-owned subsidiary of ACQUIROR ("Sub"), and HEMOXYMED, INC., a California corporation ("TARGET") (Sub and TARGET being hereinafter collectively referred to as the "Constituent Corporations").

       WHEREAS, the respective boards of directors of ACQUIROR, Sub, and TARGET have each determined that it is advisable and for the benefit and in the best interests of their corporations and their respective stockholders that TARGET be acquired by ACQUIROR (the "Acquisition") by means of a merger of TARGET with and into Sub, with Sub being the surviving corporation, on the terms and conditions hereinafter set forth (the "Merger");

       WHEREAS, the board of directors of ACQUIROR has determined that the Acquisition is consistent with and in furtherance of the long-term business strategy of ACQUIROR and is fair to, and in the best interests of, ACQUIROR and the holders of ACQUIROR Common Stock (as hereinafter defined), and has approved and adopted this Agreement and has approved the Merger and the other transactions contemplated hereby and recommended approval and adoption of the Agreement and approval of the Merger by the stockholders of ACQUIROR; and

       WHEREAS, the board of directors of TARGET has determined that the Acquisition is fair to, and in the best interests of, TARGET and the holders of TARGET Common Stock (as hereinafter defined), and has approved and adopted this Agreement and has approved the Merger and the other transactions contemplated hereby and recommended approval and adoption of the Agreement and approval of the Merger by the stockholders of TARGET;

       WHEREAS, for federal income tax purposes, it is intended that the Merger qualify as a reorganization under the provisions of Section 368(a)(1)(A) and 368(a)(2)(D) of the Code (as hereinafter defined);

       NOW, THEREFORE, in consideration of the premises, the mutual covenants, representations and warranties herein contained, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto intending to be bound hereby agree as follows:

ARTICLE 1

THE MERGER

       SECTION 1.1       The Merger. Subject to the terms and conditions hereof, on the Effective Date (as defined in Section 1.3), TARGET shall be merged with and into Sub in accordance with the applicable provisions of the General Corporation Law of the State of Delaware ("Delaware Law"); Sub, as the surviving corporation in the Merger (the "Surviving Corporation"), shall continue its corporate existence under Delaware Law; the separate existence of TARGET shall thereupon cease; and the corporate existence of TARGET shall be merged into and transferred to the Surviving Corporation.

       SECTION 1.2       Stockholders' Meetings. To the extent consistent with the fiduciary duty of their respective boards of directors, each of TARGET and ACQUIROR shall, as soon as practicable, take all action necessary in accordance with applicable law and its Certificate of Incorporation and by-laws, to convene a meeting of its stockholders to consider and vote upon the approval of the Merger (collectively, the "Stockholders' Meetings") and to solicit proxies with respect to such meeting. The board of directors of each of TARGET and ACQUIROR has recommended that its stockholders approve the Merger.

       SECTION 1.3       Consummation of the Merger; Effective Date. As soon as practicable following the Closing (as that term is hereinafter defined in Section 2.5), the parties hereto will file with the Secretary of State of the State of Delaware a Certificate of Merger in such form as required by, and executed in accordance with, the relevant provisions of Delaware Law. The Merger shall become effective at such time (the "Effective Time"), as the Certificate of Merger shall have been duly filed with the Secretary of State of the State of Delaware (the "Effective Date").

       SECTION 1.4       Effect of the Merger. Upon the effectiveness of the Merger, the Surviving Corporation shall succeed, without any other action, to all rights and property of each of the Constituent Corporations, and shall be subject to all the debts and liabilities of each of the Constituent Corporations in the same manner as if the Surviving Corporation had itself incurred them, all with the effect set forth in Delaware law.

ARTICLE 2

CONVERSION AND CANCELLATION OF SECURITIES

       SECTION 2.1       Conversion of Shares; Treatment of Warrants, Options and Convertible Securities. As of the Effective Date, by virtue of the Merger and without any action on the part of the holders thereof:

              (a)        Common Stock. On the Effective Date, each share of TARGET's Common Stock, no par value (the "TARGET Common Stock"), issued and outstanding immediately prior to the Effective Date, other than Dissenting Shares (as hereinafter defined) and other than any shares of TARGET Common Stock held by ACQUIROR, Sub or TARGET, shall, by virtue of the Merger automatically and without any action on the part of the holder thereof, become and be converted into the right to receive 0.983988 shares of fully paid and nonassessable Common Stock, $.0025 par value, of ACQUIROR (the "ACQUIROR Common Stock"). The shares of ACQUIROR Common Stock issuable in the Merger pursuant to the foregoing sentence are sometimes collectively referred to hereinafter as the "Merger Consideration".

              (b)        Capital Stock Held by TARGET, ACQUIROR or Sub. On the Effective Date, each share of capital stock of TARGET held in the treasury of TARGET, or by ACQUIROR or Sub immediately prior to the Effective Date shall, by virtue of the Merger and without any action on the part of the holder thereof, be automatically cancelled and retired and cease to exist and no securities or other consideration shall be payable in respect thereof.

       SECTION 2.2       Appraisal Rights. Holders of shares of TARGET Common Stock, who duly exercise and perfect appraisal rights under Section 1300 et seq. of the California Corporations Code (such shares referred to herein as "Dissenting Shares") shall have the appraisal rights set forth in Section 1300 et seq. of the California Corporations Code and no other rights; provided, however, that Dissenting Shares beneficially and legally owned by the holder thereof at the Effective Date who shall, after the Effective Date, withdraw the demand for appraisal or lose the right of appraisal as provided in such law, shall be deemed to be converted as of the Effective Date, into the right to receive the Merger Consideration set forth in Section 2.1 hereof.

       SECTION 2.3       Surrender and Payment. After the Effective Date, each holder of a certificate that formerly represented shares of TARGET Common Stock, issued and outstanding on the Effective Date (other than any Dissenting Shares and shares held by TARGET, ACQUIROR or Sub) shall be entitled, upon surrender thereof to the Surviving Corporation, to receive the Merger Consideration for each share of TARGET Common Stock theretofore represented by the certificate so surrendered as provided in Section 2.1 hereof, and the certificate so surrendered shall forthwith be cancelled.

       SECTION 2.4       Common Stock of Sub. Each share of common stock, par value $.01 per share, of Sub issued and outstanding on the Effective Date shall, by virtue of the Merger and without any action on the part of the holder thereof, remain outstanding and shall thereafter represent one share of common stock of the Surviving Corporation.

       SECTION 2.5       Closing. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place, unless the parties shall otherwise agree, at the offices of XxXxxxxxxx Xxxxxxx & Xxxx, Xxx Xxxx Xxxx Xxxxxx, Xxxxxxx Xxxxxxxxx at 10:00 A.M. local time (i) as soon as practicable after the day on which the last condition set forth in Article 9 shall have been fulfilled or waived or (ii) at such other time as TARGET and ACQUIROR may mutually agree (the "Closing Date").

ARTICLE 3

CERTIFICATES OF INCORPORATION and BY-LAWS

       SECTION 3.1       Certificate of Incorporation and By-Laws. As of the Effective Date, the Certificate of Incorporation and By-laws of Sub as in effect on the Effective Date shall be the Certificate of Incorporation and by-laws of the Surviving Corporation until thereafter amended as provided by Delaware Law.

       SECTION 3.2       Directors and Officers of Sub. The directors and officers of Sub at the Effective Time shall be the initial directors and officers of the Surviving Corporation and shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the Certificate of Incorporation or By-Laws of the Surviving Corporation or as otherwise provided by Delaware Law.

ARTICLE 4

CERTAIN PROVISIONS RELATING TO SHARES

       SECTION 4.1       No Fractional Shares of ACQUIROR Common Stock. No fractional shares of ACQUIROR Common Stock shall be issued by ACQUIROR in the Merger. Each stockholder of TARGET who otherwise would be entitled to a fractional interest in any share of ACQUIROR Common Stock shall receive an amount of cash (without interest) determined by multiplying the average reported last sale price of ACQUIROR Common Stock on the NASDAQ system for the five (5) trading days ending on the close of business on the second (2) business day before the Stockholders' Meeting of TARGET (the "Fair Market Value") by the fractional share interest to which such holder would otherwise be entitled. Unless and until the certificates that immediately prior to the Effective Date represented shares of TARGET Common Stock (the "Certificate(s)") shall have been surrendered, the holder of any Certificate representing the right to receive a fraction of a share of ACQUIROR Common Stock shall not be entitled to receive the cash payment described in this Section 4.1 for such fraction of a share. Such payment shall be remitted, without interest, after the surrender of the Certificates held by such holder as provided in Section 4.2.

       SECTION 4.2       ACQUIROR to Make Merger Consideration Available. ACQUIROR shall designate its stock transfer agent to act as exchange agent (the "Exchange Agent") in connection with the Merger. As soon as practicable after the Effective Date, ACQUIROR shall make available and, subject to Section 4.1, each holder of a Certificate shall be entitled to receive, upon surrender to the Exchange Agent of such Certificate for cancellation and subject to any required withholding of taxes under any applicable federal income tax laws ("Backup Withholding"), the aggregate number of shares of ACQUIROR Common Stock into which the shares of TARGET Common Stock, previously represented by each Certificate, shall have been converted in the Merger. Until so surrendered and exchanged, each Certificate (other than Certificates representing any Dissenting Shares or shares of the capital stock of TARGET held by TARGET, ACQUIROR or Sub) shall represent solely the right to receive the Merger Consideration into which the shares of TARGET Common Stock it represented prior to the Effective Date shall have been converted pursuant to Section 2.1, less any Backup Withholding. As soon as practicable after the Effective Date, ACQUIROR shall cause the Exchange Agent to mail a transmittal form to each holder of a Certificate advising such holder of the procedure for surrendering to the Exchange Agent such Certificates for payment in accordance with this Section 4.2.

       SECTION 4.3       Dividends; Transfer Taxes; Voting Rights.

              (a)       Other than as provided in Section 8.4, below, no dividends or distributions that are otherwise payable on ACQUIROR Common Stock will be paid to persons entitled to receive ACQUIROR Common Stock until such persons surrender their Certificates. Upon such surrender, there shall be paid to the person in whose name ACQUIROR Common Stock shall be issued, any dividends or distributions that shall have become payable with respect to ACQUIROR Common Stock between the Effective Date and the time of such surrender. After such surrender, there shall be paid to the person in whose name the ACQUIROR Common Stock shall be issued any dividends or distributions on ACQUIROR Common Stock which shall have a record date prior to such surrender and a payment date after such surrender, and such payment shall be made on such payment date.

              (b)       If shares of ACQUIROR Common Stock are to be issued or delivered to any person other than the person in whose name the Certificate surrendered for exchange is registered, it shall be a condition of the exchange that the person requesting such exchange shall deliver to the Exchange Agent all documents required to evidence and effect such transfer, and pay to the Exchange Agent any transfer or other taxes required by reason of the issuance or delivery of a certificate representing such shares of ACQUIROR Common Stock to other than the registered owner of the Certificate surrendered, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable.

       SECTION 4.4       Abandoned Property; Lost Certificates. Notwithstanding anything to the contrary contained herein, neither the Exchange Agent nor any party hereto shall have any liability to a holder of a Certificate for the payment of the Merger Consideration to be issued in accordance with the provisions hereof if such Merger Consideration is paid to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates shall not have been surrendered prior to three (3) years after the Effective Date (or immediately prior to such earlier date on which any payment in respect thereof would otherwise escheat to or become the property of any governmental unit or agency), the payment in respect of such Certificates shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims of interest of any person previously entitled thereto. Lost Certificates shall be treated in accordance with the normal procedures of the Exchange Agent.

       SECTION 4.5       Taking of Necessary Action; Further Action. Sub, ACQUIROR and TARGET shall each take all such action as may be necessary or appropriate in order to effectuate the Merger as promptly as possible, subject to all of the terms and conditions hereof. If, at any time after the Effective Date, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of either of the Constituent Corporations, the officers and directors of such corporation are fully authorized in the name of such corporation or otherwise to take, and shall take, all such action.

       SECTION 4.6       Closing of TARGET's Transfer Books. On the Effective Date, the stock transfer books of TARGET shall be closed and no transfer of shares of capital stock of TARGET shall thereafter be made, except for transfers of Dissenting Shares, as permitted by law. If, after the Effective Date, certificates representing shares of TARGET Common Stock are presented to the Surviving Corporation, they shall, subject to the provisions of Section 4.4 hereof, be cancelled and exchanged for the Merger Consideration provided in Section 2.1 hereof.

ARTICLE 5

REPRESENTATIONS AND WARRANTIES OF TARGET

       Except as set forth in the Disclosure Schedule to be delivered by TARGET to ACQUIROR (the "TARGET Disclosure Schedule"), which shall identify exceptions by specific Section references, to the best of its knowledge, TARGET hereby represents and warrants to ACQUIROR that:

       SECTION 5.1       Organization and Qualification; Subsidiaries. TARGET is a corporation, duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its incorporation, has all requisite power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted and is duly qualified and in good standing to do business in each jurisdiction in which the nature of the business conducted by it or the ownership or leasing of its properties makes such qualification necessary, other than where the failure to be in good standing, or to have such power and authority, or to be duly qualified and in good standing, as the case may be, would not have a TARGET Material Adverse Effect. The term "TARGET Material Adverse Effect" as used in this Agreement shall mean any event, change or effect that, individually or when taken together with all other such events, changes or effects, would be materially adverse to the condition (financial or otherwise), prospects, properties, assets, business or operations of TARGET, at the time of such event, change or effect. TARGET has no subsidiaries.

       SECTION 5.2       Certificates of Incorporation and By-Laws. TARGET has heretofore furnished to ACQUIROR complete and correct copies of the Certificates of Incorporation and the By-Laws of TARGET. TARGET is not in violation of any of the provisions of its Certificate of Incorporation or By-Laws.

       SECTION 5.3       Capitalization. As of the date of this Agreement, the authorized capital stock of TARGET consists of (i) 30,000,000 shares of TARGET Common Stock, of which: (x) 19,309,174 shares of TARGET Common Stock are issued and outstanding, all of which are duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights created by statute, common law, TARGET's Certificate of Incorporation or By-laws or, any agreement to which TARGET is a party or is bound or otherwise; and (y) no shares of TARGET Common Stock are held in the treasury of TARGET. As of the date of this Agreement, there are no options, warrants or other rights (including registration rights), agreements, arrangements or commitments of any character to which TARGET is a party relating to the issued or unissued capital stock or other securities of TARGET or obligating TARGET to grant, issue or sell any shares of the capital stock or other securities of TARGET, by sale, lease, license or otherwise, except as disclosed in Section 5.3 of the TARGET Disclosure Schedule. As of the date of this Agreement, except as set forth in Section 5.3 of the TARGET Disclosure Schedule, there are no obligations, contingent or otherwise, of TARGET to (x) repurchase, redeem or otherwise acquire any shares of TARGET Common Stock or (y) provide funds to, or make any investment in (in the form of a loan, capital contribution or otherwise), or provide any guarantee with respect to the obligations of TARGET or any other person.

       SECTION 5.4       Authority. TARGET has all requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby (other than with respect to the Merger, and the approval and adoption of this Agreement by the holders of the TARGET Common Stock in accordance with the laws of the State of California ("California Law")). The execution and delivery of this Agreement by TARGET and the consummation by TARGET of the transactions contemplated hereby have been duly authorized by all necessary corporate action and no other corporate proceedings on the part of TARGET are necessary to authorize this Agreement or to consummate the transactions contemplated hereby (other than, with respect to the approval and adoption of this Agreement, by the holders of a two-thirds majority of the outstanding shares of TARGET Common Stock in accordance with California Law). This Agreement has been duly executed and delivered by TARGET and, assuming the due authorization, execution and delivery thereof by ACQUIROR and Sub, constitutes the legal, valid and binding obligation of TARGET, enforceable against TARGET in accordance with its terms, subject to applicable bankruptcy, insolvency, moratorium or other laws affecting the enforcement of creditors' rights in general from time to time in effect and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

       SECTION 5.5       No Conflict; Required Filings and Consents.

              (a)       The execution and delivery of this Agreement by TARGET does not, and the performance of this Agreement by TARGET and the consummation of the transactions contemplated hereby will not, excepting any shareholder votes required by California Law, (i) conflict with or violate the Certificate of Incorporation or By-Laws, or the equivalent organizational documents, in each case as amended or restated, of TARGET, (ii) conflict with or violate any federal, state, foreign or local law, statute, ordinance, rule, regulation, order, judgment, arbitration award or decree (collectively, "Laws") or TARGET Permit (as hereinafter defined) in effect as of the date of this Agreement and applicable to TARGET or by which any of its properties is bound or subject to including, without limitation, Section 1203 of the California Corporations Code, or (iii) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or encumbrance on any of the properties or assets of TARGET pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, order, decree, franchise or other instrument or obligation to which TARGET is a party or by which TARGET or any of its properties is bound or is subject to, except for any such conflicts or violations described in clause (ii) or breaches, defaults, events, rights of termination, amendment, acceleration or cancellation or liens or encumbrances described in clause (iii) that would not have a TARGET Material Adverse Effect. The board of directors of TARGET has taken all actions necessary under California Law, including approving the transactions contemplated in this Agreement, to ensure that Section 1203 of the California Corporations Code does not, or will not, apply to the transactions contemplated in this Agreement.

              (b)       The execution and delivery of this Agreement by TARGET does not, and the performance of this Agreement by TARGET and the ownership and operation of the business and properties of TARGET by the Surviving Corporation following the Effective Date will not, as of the date of this Agreement, require TARGET to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any governmental or regulatory authority ("Governmental Entities"), except (i) for the filing and recordation of appropriate merger documents as required by Delaware Law and California Law; and (ii) where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not, either individually or in the aggregate, prevent TARGET from performing its obligations under this Agreement or otherwise have a TARGET Material Adverse Effect.

       SECTION 5.6       Permits; Compliance. TARGET is in possession of all franchises, grants, authorizations, licenses, permits, easements, variances, exemptions, consents, certificates, approvals and orders necessary to own, lease and operate its properties and to carry on its business as it is now being conducted (collectively, the "TARGET Permits"), and there is no action or proceeding or, to the knowledge of TARGET, investigation pending or threatened regarding suspension or cancellation of any TARGET Permits, except where the failure to possess, or the suspension or cancellation of, such TARGET Permits would not have a TARGET Material Adverse Effect. TARGET is not in conflict with, or in default or violation of (a) any Law applicable to TARGET or by which any of its properties is bound or subject to or (b) any of TARGET Permits, except for any such conflicts, defaults or violations which would not have a TARGET Material Adverse Effect.

       SECTION 5.7       Reports; Financial Statements.

              (a)       TARGET has filed all forms, reports, statements and other documents required to be filed with any other applicable federal or state regulatory authorities, except where the failure to file any such forms, reports, statements or other documents would not have a TARGET Material Adverse Effect (all such forms, reports, statements and other documents being referred to herein, collectively, as the "Reports"). The Reports, including all Reports filed after the date of this Agreement and prior to the Effective Date, (i) were or will be prepared in all material respects in accordance with the requirements of applicable Law, and (ii) did not at the time they were filed, or will not at the time they are filed, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

              (b)       Except as disclosed in Section 5.7(b) of the TARGET Disclosure Schedule, the financial statements with results through December 31, 2000 (including any related notes thereto) delivered to ACQUIROR prior to or after the date of this Agreement (i) have been or will be prepared in accordance with generally accepted accounting principles applied on a consistent basis and (ii) fairly present or will fairly present the financial position of TARGET as of the respective dates thereof and results of operations and cash flows for the periods indicated (including reasonable estimates of normal and recurring year-end adjustments), except that (A) any unaudited interim financial statements were or will be subject to normal and recurring year-end adjustments and (B) any pro forma financial information contained in such financial statements is not necessarily indicative of the financial position of TARGET as of the respective dates thereof and the results of operations and cash flows for the periods indicated.

       SECTION 5.8       Absence of Certain Changes or Events. During the period commencing January 1, 2000, and ending on the date of this Agreement, there has not been (a) a TARGET Material Adverse Effect or (b) any change by TARGET in its accounting methods, principles or practices.

       SECTION 5.9       Absence of Litigation. Except as disclosed in Section 5.9 of the TARGET Disclosure Schedule, there is no claim, action, suit, litigation, proceeding, arbitration or, to the knowledge of TARGET, investigation of any kind, at law or in equity (including actions or proceedings seeking injunctive relief), pending or, to the knowledge of TARGET, threatened in writing against TARGET or any properties or rights of TARGET (except for claims, actions, suits, litigations, proceedings, arbitrations, or investigations which, individually or in the aggregate, would not reasonably be expected to have a TARGET Material Adverse Effect), and TARGET is not subject to any continuing order of, consent decree, or, the knowledge of TARGET, continuing investigation by, any Governmental Entity, or any judgment, order, writ, injunction, decree or award of any Governmental Entity or arbitrator, including, without limitation, cease-and-desist or other orders, except for matters which, individually or in the aggregate, would not have a TARGET Material Adverse Effect.

       SECTION 5.10       Taxes. Except for such matters that would not have a TARGET Material Adverse Effect or are disclosed in Section 5.10 of the TARGET Disclosure Schedule (a) TARGET has timely filed or will timely file all returns and reports required to be filed by it with any taxing authority with respect to Taxes for any period ending on or before the Effective Date, taking into account any extension of time to file granted to or obtained on behalf of TARGET, (b) all Taxes shown to be payable on such returns or reports that are due prior to the Effective Date have been paid or will be paid when due, (c) as of the date hereof, no deficiency for any material amount of Tax has been asserted or assessed by a taxing authority against TARGET, (d) all liability for Taxes of TARGET that are or will become due or payable with respect to periods covered by the financial statements referred to in Section 5.7(b) hereof have been paid or adequately reserved for on such financial statements and (e) no Tax return or reports of TARGET are under examination.

       SECTION 5.11       Certain Business Practices.

REPRESENTATIONS AND WARRANTIES OF ACQUIROR AND SUB

       Except as set forth in the Disclosure Schedule to be delivered by ACQUIROR and Sub to TARGET (the "ACQUIROR Disclosure Schedule"), which shall identify exceptions by specific Section references, to the best knowledge of each of them, ACQUIROR and Sub hereby represent and warrant to TARGET that:

       SECTION 6.1       Organization and Qualification; Subsidiaries. Each of ACQUIROR and Sub is a corporation, duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its incorporation, has all requisite power and authority to own, lease and operate its properties and to carry on its business as it is now being conducted and is duly qualified and in good standing to do business in each jurisdiction in which the nature of the business conducted by it or the ownership or leasing of its properties makes such qualification necessary, other than where the failure to be in good standing, or to have such power and authority, or to be duly qualified and in good standing, as the case may be, would not have a ACQUIROR Material Adverse Effect. The term "ACQUIROR Material Adverse Effect" as used in this Agreement shall mean any event, change or effect that, individually or when taken together with all other such events, changes or effects, would be materially adverse to the condition (financial or otherwise), prospects, properties, assets, business or operations of ACQUIROR and Sub, taken as a whole, at the time of such event, change or effect. Other than Sub, ACQUIROR has no subsidiaries.

       SECTION 6.2       Certificate of Incorporation and By-Laws. ACQUIROR has heretofore furnished to TARGET complete and correct copies of the Certificates of Incorporation and the By-Laws or the equivalent organizational documents in each case, as amended or restated, of ACQUIROR and Sub. Neither ACQUIROR nor Sub is in violation of any of the provisions of its Certificate of Incorporation or By-Laws.

       SECTION 6.3       Capitalization. As of the date of this Agreement, the authorized capital stock of ACQUIROR consists of (a) 22,400,000 shares of ACQUIROR Common Stock and (b) 2,000,000 shares of preferred stock, par value $0.001 per share ("ACQUIROR Preferred Stock"). As of the date of this Agreement: (i) 1,158,249 shares of ACQUIROR Common Stock are issued and outstanding, all of which are duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights created by statute, common law, ACQUIROR's Certificate of Incorporation or By-Laws, or any agreement to which ACQUIROR is a party or is bound or otherwise; (ii) no shares of ACQUIROR Common Stock are held in treasury; (iii) 241,636 shares of ACQUIROR Common Stock are reserved for future issuance pursuant to outstanding warrants; and (iv) 7,933 shares of ACQUIROR Common Stock are reserved for future issuance pursuant to outstanding stock options issued to certain officers, employees, directors, consultants and other persons. As of the date of this Agreement, no shares of ACQUIROR Preferred Stock are issued and outstanding. The shares of ACQUIROR Common Stock to be issued in the Merger have been duly authorized and, when issued in accordance with the Merger, will be validly issued, fully paid and nonassessable. As of the date of this Agreement, there are no options, warrants or other rights (including registration rights), agreements, arrangements or commitments of any character to which ACQUIROR is a party relating to the issued or unissued capital stock or other securities of ACQUIROR to grant, issue or sell any shares of the capital stock or other securities of ACQUIROR, by sale, lease, license or otherwise, except (A) as disclosed in Section 6.3 of the ACQUIROR Disclosure Schedule and (B) for options to purchase ACQUIROR Common Stock under ACQUIROR's existing stock option plans to the extent stock options for such shares thereunder have not yet been granted. As of the date of this Agreement, there are no obligations, contingent or otherwise, of ACQUIROR to repurchase, redeem or otherwise acquire any shares of ACQUIROR Common Stock.

       SECTION 6.4       Authority. Each of ACQUIROR and Sub has all requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby (other than with respect to the Merger, the approval and adoption of this Agreement by the holders of the ACQUIROR Common Stock in accordance with applicable law or the rules of the NASD). The execution and delivery of this Agreement by ACQUIROR and Sub and the consummation by ACQUIROR and Sub of the transactions contemplated hereby have been duly authorized by all necessary corporate action and no other corporate proceedings on the part of ACQUIROR or Sub are necessary to authorize this Agreement or to consummate the transactions contemplated hereby (other than, with respect to the approval and adoption of this Agreement, by the holders of a majority of the outstanding shares of ACQUIROR Common Stock in accordance with Delaware Law). This Agreement has been duly executed and delivered by ACQUIROR and Sub and, assuming the due authorization, execution and delivery thereof by TARGET, constitutes a legal, valid and binding obligation of ACQUIROR and Sub enforceable against ACQUIROR and Sub in accordance with its terms, subject to applicable bankruptcy, insolvency, moratorium or other laws affecting the enforcement of creditors' rights in general from time to time in effect and general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

       SECTION 6.5       No Conflict; Required Filings and Consents.

              (a)       The execution and delivery of this Agreement by ACQUIROR and Sub does not, and the performance of this Agreement by ACQUIROR and Sub and the consummation of the transactions contemplated hereby will not, excepting any stockholder votes required by applicable law or the rules of the NASD, (i) conflict with or violate the Certificate of Incorporation or By-Laws, as amended or restated, of ACQUIROR or Sub, (ii) conflict with or violate any Laws or ACQUIROR Permit (as hereinafter defined) in effect as of the date of this Agreement applicable to ACQUIROR or Sub or by which any of their respective properties is bound or subject to, including, without limitation, Section 203 of Delaware Law or (iii) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or encumbrance on the properties or assets of ACQUIROR or Sub pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, order, decree, franchise or other instrument or obligation to which ACQUIROR or Sub is a party or by which ACQUIROR or Sub or any of their respective properties is bound or subject to, except for any such conflicts or violations described in clause (ii) or breaches, defaults, events, rights of termination, amendment, acceleration or cancellation or liens or encumbrances described in clause (iii) that would not have a ACQUIROR Material Adverse Effect. The board of directors of ACQUIROR has taken all actions necessary under Delaware Law, including approving the transactions contemplated in this Agreement, to ensure that Section 203 of Delaware Law does not, or will not, apply to the transactions contemplated in this Agreement. As used herein, "ACQUIROR Permit" shall mean all franchises, grants, authorizations, licenses, permits, easements, variances, exemptions, consents, certificates, approvals and orders necessary for ACQUIROR to own, lease and operate its properties and to carry on its business as it is now being conducted.

       SECTION 6.6       Permits; Compliance. Each of ACQUIROR is in possession of all franchises, grants, authorizations, licenses, permits, easements, variances, exemptions, consents, certificates, approvals and orders necessary to own, lease and operate its properties and to carry on its business as it is now being conducted (collectively, the "ACQUIROR Permits"), and there is no action or proceeding or, to the knowledge of ACQUIROR, investigation pending or threatened regarding suspension or cancellation of any ACQUIROR Permits, except where the failure to possess, or the suspension or cancellation of, such ACQUIROR Permits would not have a ACQUIROR Material Adverse Effect. ACQUIROR is not in conflict with, or in default or violation of (a) any Law or any rule of professional conduct applicable thereto and applicable to ACQUIROR or by which any of their respective properties is bound or subject to or (b) any of ACQUIROR Permits, except for any such conflicts, defaults or violations which would not have a ACQUIROR Material Adverse Effect.

TARGET and ACQUIROR shall each use its reasonable best efforts to prepare, file and distribute all necessary proxy statements in order to solicit from their respective stockholders proxies in favor of the approval and adoption of this Agreement and to secure the vote or consent of stockholders required by Delaware Law, California Law or NASDAQ regulations, as the case may be, to approve and adopt this Agreement, unless otherwise required by the applicable fiduciary duties of the directors of TARGET or ACQUIROR, as determined by such directors in good faith after consultation with independent legal counsel.

All documents that ACQUIROR is responsible for filing with the SEC in connection with the transactions contemplated herein will comply as to form and substance in all material respects with the applicable requirements of the Securities Act and the rules and regulations thereunder and the Exchange Act and the rules and regulations thereunder.

       SECTION 8.3       Appropriate Action; Consents; Filings.

              (a)       Each of ACQUIROR and TARGET shall use its best efforts to  take, or cause to be taken, all appropriate action, and do, or cause to be done, all things necessary, proper or advisable under applicable Law or otherwise to consummate, satisfy the conditions to, and make effective the transactions contemplated by this A greement;  obtain from any Governmental Entities or other persons any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by ACQUIROR or TARGET in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated herein; make all necessary filings, and thereafter make any other required submissions, with respect to this Agreement required under (A) the Securities Act and the Exchange Act and the rules and regulations thereunder, and any other applicable federal or state securities laws, and (B) any other applicable Laws.

              (b)       Without limiting the application of Article 7 hereof and subject to the respective fiduciary obligations of the directors of each of ACQUIROR and TARGET, each of ACQUIROR and TARGET agrees to use its best efforts vigorously to contest and resist any action, including administrative or judicial action, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) (an "Order") that is in effect and that restricts, prevents or prohibits the consummation of any of the transactions contemplated by this Agreement, including, without limitation, by vigorously pursuing all available avenues of administrative and judicial appeal; provided, however, that in no event shall ACQUIROR or TARGET take, or be required to take, any action that would have a material adverse effect on its operations, assets, financial condition or prospects.

       SECTION 8.4       Distributions; Dividends; Liquidating Trust.

              (a)       Between the date hereof and the Closing Date, ACQUIROR shall be authorized to make one or more liquidating distributions to its then stockholders of record (the "Pre-Closing Stockholders") of all, or substantially all, of the proceeds of the Promega Asset Sale (as herein defined). In addition, the ACQUIROR board of directors shall be permitted to establish a liquidating trust for the purpose of receiving, on or prior to the Closing Date, $50,000 of the cash assets of ACQUIROR, and retaining and distributing therefrom after the Closing Date such amounts as the trustee thereof deems necessary for payment of any liabilities arising within ninety (90) days of the Closing Date, including any liabilities arising out of the breach by ACQUIROR of any of its representations and warranties pursuant to this Agreement. TARGET agrees that any right it may have to claim against the assets of the liquidating trust established hereunder is limited to the $50,000 provided under the preceding sentence and that any such claims must be made within the ninety (90) day period following the Closing Date. In addition, ACQUIROR may transfer to such trust on or prior to the Closing Date such additional funds as the ACQUIROR's Board of Directors deem appropriate to hold and to pay any other claims against ACQUIROR that exist on the Closing Date or arise thereafter. The trustee of the liquidating trust shall, in his sole discretion, determine the disposition of any claims against the assets of the trust and distribute any amounts remaining in such trust after payment, settlement, or denial of all such claims to the Pre-Closing Stockholders in proportion to the percentage of ACQUIROR Common Stock owned by each such Pre-Closing Stockholder on such day before the Closing Date. For purposes of this Section 8.4, the term "Promega Asset Sale" shall mean the consummated transactions contemplated by that certain Asset Purchase Agreement dated as of September 1, 2000, between Promega Corporation, as Buyer, and ACQUIROR, as Seller.

              (b)       On the Effective Date ACQUIROR shall be authorized to effect a stock dividend to the Pre-Closing Stockholders, as defined above, of 0.036046 shares of ACQUIROR Common Stock for each share of ACQUIROR Common Stock held by the Pre-Closing Stockholders of record immediately prior to the Effective Date. No fractional shares of ACQUIROR Common Stock shall be issued by ACQUIROR in connection with the dividend authorized under this Section 8.4(b). Each Pre-Closing Stockholder who otherwise would be entitled to a fractional interest in any share of ACQUIROR Common Stock shall receive an amount of cash (without interest) determined by multiplying the average reported last sale price of ACQUIROR Common Stock on the NASDAQ system for the five (5) trading days ending on the close of business on the second (2^nd) business day before the Stockholders' Meeting of TARGET (the "Fair Market Value") by the fractional share interest to which such holder would otherwise be entitled.

       SECTION 8.5       Public Announcements. Unless otherwise required by applicable Law or stock exchange requirements or the requirements of the NASD (and in that event only if time does not permit), ACQUIROR and TARGET shall consult with each other before issuing any press release or otherwise making any public statements with respect to the Merger and the transactions contemplated thereby and shall not issue any such press release or make any such public statement prior to such consultation.

       SECTION 8.6       NASDAQ Listing. The Parties shall use their best efforts to cause the listing of ACQUIROR for trading on the NASDAQ over-the-counter Bulletin Board to be changed to reflect the change of its corporate name to the corporate name of TARGET, as soon as practicable after the Effective Date.

              (a)       By mutual written consent of ACQUIROR and TARGET;

              (b)       By ACQUIROR, if any representation or warranty made by TARGET in this Agreement shall not have been true when made and such breach would have been, or would be, reasonably likely to have a TARGET Material Adverse Effect or the failure of TARGET to satisfy its obligations under Section 9.2(b);

              (c)       By TARGET, if any representation or warranty made by ACQUIROR in this Agreement shall not have been true when made and such breach would have been, or would be, reasonably likely to have an ACQUIROR Material Adverse Effect or the failure of ACQUIROR to satisfy its obligations under Section 9.3(b);

              (d)       By either ACQUIROR or TARGET, if there shall be any Order which is final and non-appealable preventing the consummation of the Merger, except if the party relying on such Order has not complied with its obligations under Section 8.3(b);

              (e)       By either ACQUIROR or TARGET, if the Effective Date shall not have occurred before July 1, 2001; provided, however, that the right to terminate this Agreement pursuant to this Section 10.1(e) shall not be available to any party whose breach of any representation or warranty or failure to perform or comply with any obligation under this Agreement has been the cause of, or resulted in, the failure of the Effective Date to occur on or before such date;

              (f)       By either ACQUIROR or TARGET, if the Agreement shall fail to receive the requisite votes for approval and adoption by the stockholders of each of TARGET and ACQUIROR at the Stockholders' Meeting of either of them, or if any of the conditions specified in Section 9.1 shall not have been met in all material respects or waived prior to such time as such condition can no longer be satisfied;

              (g)       By either ACQUIROR or TARGET, at any time prior to 11:59 p.m. New York City time on the tenth business day following the delivery by the other party of the Disclosure Schedules pursuant to Section 8.7 hereof (or at such later date as mutually agreed upon by the parties hereto), if the results of its due diligence investigation of the other party's affairs and business operations or the information disclosed on the respective Disclosure Schedules make it inadvisable or undesirable in such party's sole and reasonable discretion to proceed with the transactions contemplated hereby;

              (h)       by ACQUIROR or TARGET at any time prior to the Effective Date if (i) in the case of termination by ACQUIROR, any of the conditions specified in Section 9.2(a) and 9.2(c) through (g) shall not have been met or waived prior to such time as such condition can no longer be satisfied or (ii) in the case of termination by TARGET, any of the conditions specified in Section 9.3(a) and 9.3(c) through (f) shall not have been met or waived prior to such time as such condition can no longer be satisfied; or

       SECTION 10.5       Fees, Expenses and Other Payments.

              (a)       Except as provided in Sections 7.6(b) or 10.2, all Expenses (as defined in paragraph (b) of this Section 10.5) incurred by the parties hereto shall be borne solely and entirely by the party that has incurred such Expenses.

              (c)       If this Agreement shall be terminated (i) by TARGET pursuant to Section 10.1(c), or (ii) by ACQUIROR pursuant to Section 10.1(b) (either of such events in (i) and (ii) shall be deemed a "Breach Event"), then the other party shall pay to the non-breaching party (TARGET in (i), and ACQUIROR in (ii) are herein referred to as a "Non-Breaching Party"), in consideration of the time, effort and resources expended in connection herewith, an amount equal to, in the case of a Breach Event, the Non-Breaching Party's actual Expenses incurred up to the Termination Date, but in no event shall such payment exceed $50,000, plus in all such cases, any fees or expenses incurred by the Non-Breaching Party in connection with the collection of such amount (the "Collection Expenses").

              (d)       Any payment required to be made pursuant to Section 10.5(c) shall be made to the Non-Breaching Party entitled to receive such payment not later than ten (10) days after delivery to the other party of notice of demand for payment and an itemization setting forth in reasonable detail all Collection Expenses, if any, of the Non-Breaching Party and shall be made by wire transfer of immediately available funds to an account designated by the Non-Breaching Party in the notice of demand for payment delivered pursuant to this Section 10.5(d).
