INTRODUCTION

Pursuant hereto, and subject to the terms hereof, the parties hereto intend that OncoVista shall merge (the “Merger”) with Acquisition pursuant to Section 251 of the General Corporation Law of the State of Delaware (the “DGCL”).
 

I.  NAME OF SURVIVING CORPORATION; CERTIFICATE OF
INCORPORATION AND BY-LAWS; BOARD OF DIRECTORS; OFFICERS
 
Section 1.01 Name of Surviving Corporation.  The corporation which shall survive the Merger contemplated hereby is OncoVista.
 
Section 1.02 Certificate of Incorporation and By-laws. The certificate of incorporation and the by-laws of OncoVista as in effect at the Effective Time shall, from and after the Effective Time, be the certificate of incorporation and the by-laws of the Surviving Corporation until they are amended.
 
Section 1.03 Board of Directors and Officers.

(a) The directors and officers of OncoVista at the Effective Time shall be the directors and officers, respectively, of the Surviving Corporation, each to serve, in each case (subject to the Surviving Corporation’s by-laws), until their respective successors shall have been elected and qualified.

(b) The sole director of AVUG immediately prior to the Effective Time shall appoint the directors of OncoVista at the Effective Time as the directors of AVUG commencing at the close of business on the last day of the Gap Period, each to serve, in each case (subject to the by-laws of AVUG), until their respective successors shall have been elected and qualified. The sole director of AVUG immediately prior to the Effective Time shall appoint the officers of OncoVista at the Effective Time as the officers of AVUG commencing at the Effective Time, each to serve, in each case (subject to the by-laws of AVUG), until their respective successors shall have been elected and qualified.  For purposes of this Agreement, the term “Gap Period” shall mean the period commencing at the Effective Time and terminating on the tenth day following the transmission by AVUG to the holders of record of securities of AVUG the information referenced in Section 5.02(m) of this Agreement. 



II. STATUS AND CONVERSION OF SECURITIES
 
Section 2.01 Stock of OncoVista. 

(a) Each share of common stock of OncoVista (“OncoVista Common Stock”) outstanding at the Effective Time shall, subject to compliance with Section 2.01(d), be converted into and exchanged for one share of common stock of AVUG (giving effect to the Stock Split as hereinafter defined, “AVUG Common Stock”).

(b) Notwithstanding Section 2.01(a) of this Agreement, merger consideration shall not be issued in respect of any shares of OncoVista Common Stock, the holders of which shall object to the Merger in writing and demand payment of the value of their shares of OncoVista Common Stock pursuant to, and in accordance with, Section 262 of the DGCL and as a result payment therefor is made. Such holders shall have only the rights provided by such Section 262.

(c) Subject to the provisions of Section 2.01(b) of this Agreement, after the Effective Time, each holder of an outstanding certificate or certificates (the “Old Certificates”) theretofore representing shares of OncoVista Common Stock, upon surrender thereof to Interwest Transfer Company, Inc. (the “Exchange Agent”), shall be entitled to receive in exchange therefor a certificate or certificates (the “New Certificates”) for the number of shares of AVUG Common Stock represented by such Old Certificate or Old Certificates, which AVUG agrees to make available to the Exchange Agent as soon as practicable after the Effective Time, representing the number of shares of AVUG Common Stock into and for which the shares of OncoVista Common Stock theretofore represented by such surrendered Old Certificates have been converted. No certificates or scrip for fractional shares of AVUG Common Stock will be issued, no AVUG stock split or dividend shall relate to any fractional share interest, and no such fractional share interest shall entitle the owner thereof to vote or to any rights of a stockholder of AVUG. In lieu of the issuance or recognition of fractional shares of AVUG Common Stock or interests or rights therein, the Exchange Agent shall round such fraction to the next higher whole number of shares of AVUG Common Stock. Until surrendered and exchanged, each Old Certificate shall after the Effective Time be deemed for all corporate purposes, other than the payment of dividends or liquidating or other distributions, if any, to holders of record of AVUG Common Stock, to represent only the right to receive the number of shares of AVUG Common Stock into and for which the shares of OncoVista Common Stock theretofore represented by such Old Certificate shall have been converted. No dividend or liquidating or other distribution, if any, payable to holders of record of shares of OncoVista Common Stock at or after the Effective Time on shares of AVUG Common Stock, or payable subsequent to the Effective Time to holders of record of shares of OncoVista Common Stock at a time prior to the Effective Time shall be paid to the holders of Old Certificates; provided, however, that upon surrender and exchange of such Old Certificates there shall be paid (subject to the last sentence of this Section 2.01(c)) to the record holders of the New Certificates issued in exchange therefor (i) the amount, without interest thereon, of dividends and liquidating or other distributions, if any, which theretofore have become payable to holders of record of shares of OncoVista Common Stock on or after the Effective Time with respect to the number of whole shares of AVUG Common Stock represented by such New Certificates and (ii) the amount, without interest thereon, of dividends and liquidating or other distributions, if any, declared by OncoVista payable to holders of record of shares of OncoVista Common Stock at a time prior to the Effective Time, but payable subsequent to the Effective Time.  If outstanding Old Certificates are not surrendered and exchanged for shares of AVUG Common Stock pursuant hereto prior to two years after the Effective Time (or, in any particular case, prior to the date before the second anniversary of the Effective Time on which the shares of AVUG Common Stock pursuant hereto and the dividends and liquidating or other distributions, if any, would otherwise escheat to, or become the property of, any governmental unit or any agency thereof), then the following shall become the property of AVUG (and, to the extent not in its possession, shall be paid over to it), free and clear of all claims or interest of any other person previously entitled thereto: (i) the number of whole shares of AVUG Common Stock into and for which the shares of OncoVista Common Stock theretofore represented by such Old Certificates shall have been converted, (ii) the amount of dividends and liquidating or other distributions, if any, which theretofore have become payable to holders of record on or after the Effective Time with respect to such number of whole shares of AVUG Common Stock, (iii) the amount of dividends and liquidating or other distributions, if any, declared by OncoVista payable to holders of record of shares of OncoVista Common Stock at a time prior to the Effective Time, but payable subsequent to the Effective Time, and (iv) the amount of dividends and liquidating or other distributions, if any, which subsequently become payable with respect to such number of whole shares of AVUG Common Stock.
 
2


(d) If any New Certificate is to be issued in a name other than that in which the Old Certificate surrendered for exchange is issued, the Old Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the person requesting such exchange shall pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of the New Certificate in any name other than that of the registered holder of the Old Certificate surrendered, or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(e) As of the Effective Time, no transfer of the shares of OncoVista Common Stock outstanding prior to the Effective Time shall be made on the stock transfer books of the Surviving Corporation. If, after the Effective Time, Old Certificates are presented to AVUG or the Surviving Corporation, they shall be exchanged pursuant to Section 2.01(c).

(a) At the Effective Time, AVUG shall assume each option (each a “OncoVista Stock Option”) outstanding at the Effective Time granted by OncoVista prior to the Effective Time by executing and delivering to such holder an assumption and AVUG shall be substituted for OncoVista with respect to each OncoVista Stock Option so assumed, and thereafter, until any event that affects the exercise price, each OncoVista Stock Option assumed by AVUG as aforesaid shall represent an option to purchase, instead of OncoVista Common Stock, the number of whole shares of AVUG Common Stock which equals the number of shares of OncoVista Common Stock subject to such option immediately prior to the Effective Time; and the price per share of AVUG Common Stock at which such option shall be exercisable shall (until any event that affects the exercise price) be an amount (to the next higher whole cent) equal to the option price per share of OncoVista Common Stock immediately prior to the Effective Time. Except as aforesaid, the period during which, and the terms upon which, each OncoVista Stock Option may be exercised shall remain unchanged.

(b) At the Effective Time, AVUG shall assume each warrant (each a “OncoVista Warrant”) outstanding at the Effective Time granted or sold by OncoVista prior to the Effective Time by executing and delivering to such holder an assumption and AVUG shall be substituted for OncoVista with respect to each OncoVista Warrant so assumed, and thereafter, until any event that affects the exercise price, each OncoVista Warrant assumed by AVUG as aforesaid shall represent an option to purchase, instead of OncoVista Common Stock, the number of whole shares of AVUG Common Stock which equals the number of shares of OncoVista Common Stock subject to such option immediately prior to the Effective Time; and the price per share of AVUG Common Stock at which such option shall be exercisable shall (until any event that affects the exercise price) be an amount (to the next higher whole cent) equal to the option price per share of OncoVista Common Stock immediately prior to the Effective Time. Except as aforesaid, the period during which, and the terms upon which, each OncoVista Warrant may be exercised shall remain unchanged.
 
(c) At the Effective Time, each note convertible into OncoVista Common Stock outstanding at the Effective Time granted or sold by OncoVista prior to the Effective Time (each an “OncoVista Note”) shall be convertible into, instead of OncoVista Common Stock, the number of whole shares of AVUG Common Stock which equals the number of shares of OncoVista Common Stock subject to such convertible note immediately prior to the Effective Time; and the price per share of AVUG Common Stock at which such convertible note shall be convertible shall (until any event that affects the conversion price) be an amount (to the next higher whole cent) equal to the conversion price per share of OncoVista Common Stock immediately prior to the Effective Time. Except as aforesaid, the period during which, and the terms upon which, each OncoVista Note may be exercised shall remain unchanged.
 
Section 2.03 Affiliates of OncoVista. Each of OncoVista and AVUG agrees that it will use its best efforts to avoid violating the securities laws of the United States or of any state or other jurisdiction while pursuing the Merger and the other transactions contemplated hereby.

Section 2.04 Capital Stock of AVUG.  Except as contemplated by this Agreement, all issued shares of AVUG Common Stock, whether outstanding or held in the treasury of AVUG, shall continue unchanged as shares of capital stock of AVUG.

(j) AVUG shall timely prepare and file any declaration or filing necessary to comply with any transfer tax statutes that require any such filing before the Effective Time.

(iii) The operations and businesses of AVUG have been conducted in all respects only in the ordinary course.  There is no fact known to AVUG or Acquisition which materially adversely affects or in the future (as far as AVUG or Acquisition can reasonably foresee) may materially adversely affect the financial condition, results of operations, businesses, properties, assets, liabilities, or future prospects of AVUG and Acquisition, and, after the Merger, the Surviving Corporation; provided, however, that neither AVUG nor Acquisition expresses any opinion as to political or economic matters of general applicability. AVUG has made known, or caused to be made known, to the accountants or auditors who have prepared, reviewed, or audited the aforementioned consolidated financial statements all material facts and circumstances which could affect the preparation, presentation, accuracy, or completeness thereof.

(h) Subsequent to the respective dates as of which information is given in the SEC Documents, there has not been (i) any material adverse change in the consolidated business, prospects, financial condition or results of operations of AVUG, (ii) any transaction committed to or consummated that is material to AVUG and Acquisition taken as a whole, (iii) any obligation, direct or contingent, that is material to AVUG and Acquisition taken as a whole incurred by AVUG or Acquisition, (iv) any change in the capital stock or outstanding indebtedness of AVUG or Acquisition that is material to AVUG and Acquisition taken as a whole, (v) any dividend or distribution of any kind declared, paid, or made on the capital stock of AVUG or Acquisition, or (vi) any loss or damage (whether or not insured) to the property of AVUG or Acquisition which has a material adverse effect on the business, prospects, condition (financial or otherwise), or results of operations thereof, in each case, taken as a whole.

The execution, delivery, and performance of this Agreement by each of AVUG and Acquisition will not cause any Taxes to be payable or cause any lien, charge, or encumbrance to secure any Taxes to be created either immediately or upon the nonpayment of any Taxes. The Internal Revenue Service has audited and settled or the statute of limitations has run upon all federal income tax returns of AVUG for all taxable years up to and including the taxable year ended December 31, 2000.

(n) AVUG has been advised concerning the Investment Company Act of 1940, as amended (the “Investment Company Act”), and the rules and regulations thereunder, and has in the past conducted, and intends in the future, to conduct its affairs in such a manner as to ensure that it is not and will not become an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act and such rules and regulations.

26

(o) (i) AVUG has not, and no person or entity acting on behalf or at the request of AVUG has, at any time during the last five years (i) made any unlawful contribution to any candidate for foreign office or failed to disclose fully any contribution in violation of law, or (ii) made any payment to any federal or state governmental officer or official, or other person charged with similar public or quasi-public duties, other than payments required or permitted by the laws of the United States or any other applicable jurisdiction.

Neither AVUG nor Acquisition is in violation or breach of, or in default with respect to, any term of its respective certificate of incorporation (or other charter document) by-laws.
 
28

(y) No representation or warranty by AVUG or Acquisition in this Agreement contains, or at the Effective Time, will contain an untrue statement of material fact or omits or at the Effective Time will omit to state a material fact required to be stated therein or necessary to make the statements made not misleading. Notwithstanding the foregoing, such representations and warranties by AVUG and Acquisition shall be deemed to comply with, and not be in breach or contravention of, or in default with respect to the immediately preceding sentence to the extent that such representations and warranties shall at the Effective Time be untrue in any material respect or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading as a result of any transaction contemplated hereby or in connection herewith.

If the Merger is abandoned or terminated as provided for in Article VII or in this Article VIII, except for Sections 5.01(i), 5.02(e) and 5.02(n), and Article IX, this Agreement shall forthwith become wholly void and of no further force or effect without liability on the part of either party to this Agreement or on the part of any officer, director, controlling person (if any), employee, counsel, agent, or stockholder thereof; provided, however, that nothing in this Section 8.03 shall release AVUG, Acquisition, or OncoVista or any officer, director, controlling person (if any), employee, counsel, agent, or stockholder thereof from liability for a willful failure to carry out its respective obligations under this Agreement.
 
IX. MISCELLANEOUS

Section 9.01 Further Actions. At any time and from time to time, each party agrees, at its expense, to take such actions and to execute and deliver such documents as may be reasonably necessary to effectuate the purposes of this Agreement.

Section 9.02 Availability of Equitable Remedies. Since a breach of the provisions of this Agreement could not adequately be compensated by money damages, any party shall be entitled, either before or after the Effective Time, in addition to any other right or remedy available to it, to an injunction restraining such breach or threatened breach and to specific performance of any such provision of this Agreement, and, in either case, no bond or other security shall be required in connection therewith, and the parties hereby consent to the issuance of such an injunction and to the ordering of specific performance.

Section 9.03 Survival; Knowledge. The covenants, agreements, representations, and warranties contained in or made pursuant to this Agreement shall not survive the Effective Time, except for those contained in or made pursuant to Sections 2.01, and Article IX. The statements contained in any document executed by AVUG or Acquisition relating hereto or delivered to OncoVista in connection with the transactions contemplated hereby or thereby, or in any statement, certificate, or other instrument delivered by or on behalf of AVUG or Acquisition pursuant hereto or thereto or delivered to OncoVista in connection with the transactions contemplated hereby or thereby shall be deemed representations and warranties, covenants and agreements, or conditions, as the case may be, of AVUG and Acquisition hereunder for all purposes of this Agreement (including all statements, certificates, or other instruments delivered pursuant hereto or thereto or delivered in connection with this Agreement, the Merger, or any of the other transactions contemplated hereby or thereby). The statements contained in any document executed by OncoVista relating hereto or delivered to AVUG or Acquisition in connection with the transactions contemplated hereby or thereby, or in any statement, certificate, or other instrument delivered by or on behalf of OncoVista pursuant hereto or thereto or delivered to AVUG or Acquisition in connection with the transactions contemplated hereby or thereby shall be deemed representations and warranties, covenants and agreements, or conditions, as the case may be, of OncoVista hereunder for all purposes of this Agreement (including all statements, certificates, or other instruments delivered pursuant hereto or thereto or delivered in connection with this Agreement, the Merger, or any of the other transactions contemplated hereby or thereby). For the purposes of this Agreement, where an entity represents and warrants a fact “to its knowledge” or “to the best of its knowledge” it shall have imputed to its knowledge only the actual conscious awareness of facts or other information, without investigation, of the executive officers and the chief financial officer of the entity and its subsidiaries. Where an individual represents and warrants a fact “to the best of the individual’s knowledge” the individual shall have imputed to that individual only the actual conscious awareness of facts or other information, without investigation, of that individual.

Section 9.04 Modification. This Agreement sets forth the entire understanding of the parties with respect to the subject matter hereof (except as provided in Section 9.03) and supersedes all existing agreements among them concerning such subject matter. This Agreement may be amended prior to the Effective Time (notwithstanding stockholder adoption and approval) by a written instrument executed by AVUG, Acquisition, and OncoVista with the approval of their respective Boards of Directors; provided, however, that no such amendment shall, without stockholder adoption and approval by an appropriate vote by stockholders of the Constituent Corporation whose stockholders have been adversely affected, change the number of shares of AVUG Common Stock which may be issued pursuant to this Agreement, or materially and adversely affect the rights of AVUG or OncoVista stockholders. No amendment to accelerate or postpone the Effective Time shall be deemed to change such number of shares or affect adversely the rights of the AVUG or OncoVista stockholders.

Section 9.05 Notices. All notices under this Agreement must be in writing and addressed, if to AVUG or Acquisition, to its corporate secretary, and if to OncoVista, to its chief executive officer. Any notice or other communication in connection with this Agreement shall be deemed to have been given (i) if personally delivered to a party, when so delivered, (ii) (A) if by certified mail, three business days after mailing or (B) if by Federal Express or other recognized next day carrier timely posted for next business day delivery, the next business day following such timely posting, to the address of such party set forth in the preamble to this Agreement (or to such other address as the party shall have furnished in writing in accordance with the provisions of this Section 9.05), or (iii) if by facsimile, once transmitted (provided that the appropriate answer back or telephonic confirmation is received), if to AVUG at 14785 Omicron Drive, Suite 104, San Antonio, Texas 78245 and if to OncoVista at 14785 Omicron Drive, Suite 104, San Antonio, Texas 78245. Either party may change the address or facsimile number to which notices or other communications hereunder are to be delivered by giving the other party notice in the manner set forth.

Section 9.06 Waiver. Any waiver by any party of a breach of any term of this Agreement shall not operate as or be construed to be a waiver of any other breach of that term or of any breach of any other term of this Agreement. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. Any waiver must be in writing and be authorized by a resolution of the Board of Directors or by an officer of the waiving party. No party shall have the right to waive compliance with Section 8.01, the second sentence of Section 9.04, or this sentence.
 
Section 9.07 Binding Effect. The provisions of this Agreement shall be binding upon and inure to the benefit of AVUG, Acquisition, and OncoVista and their respective successors and assigns and shall inure to the benefit of each indemnitee hereunder and its successors and assigns (if not a natural person) and his assigns, heirs, and personal representatives (if a natural person).

Section 9.08 No Third-Party Beneficiaries. This Agreement does not create, and shall not be construed as creating, any rights enforceable by any person not a party to this Agreement except for the OncoVista stockholders with respect to Sections 2.01, and except as provided in Section 9.07.
 
Section 9.09 Severability.  If any provision of this Agreement is invalid, illegal, or unenforceable, the balance of this Agreement shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances, provided, however, that the economic and legal substance of the transactions contemplated by this Agreement are not affected in any way materially adverse to any party hereto.

Section 9.10 Headings. The headings in this Agreement are solely for convenience of reference and shall be given no effect in the construction or interpretation of this Agreement.

Section 9.11 Counterparts; Governing Law. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. It shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to conflict of laws. Any action, suit, or proceeding arising out of, based on, or in connection with this Agreement, any document relating hereto or delivered in connection with the transactions contemplated hereby, any statement, certificate, or other instrument delivered by or on behalf of, or delivered to, any party hereto or thereto in connection with the transactions contemplated hereby or thereby, any breach of this Agreement or such other document, the Merger, or the other transactions contemplated hereby or thereby may be brought only in the state courts of the State of Delaware located in Kent County, or in the United States District Court for the District of Delaware, and each party covenants and agrees not to assert, by way of motion, as a defense, or otherwise, in any such action, suit, or proceeding, any claim that it is not subject personally to the jurisdiction of such court if it has been duly served with process, that its property is exempt or immune from attachment or execution, that the action, suit, or proceeding is brought in an inconvenient forum, that the venue of the action, suit, or proceeding is improper, or that this Agreement or the subject matter hereof may not be enforced in or by such court.
