Nanogen, Merger Sub and Nanotronics are sometimes referred to herein individually as a "Party" or collectively as the "Parties." W I T N E S S E T H: WHEREAS, the Boards of Directors of Nanogen, Merger Sub and Nanotronics deem it advisable and in the best interests of their respective shareholders to effect the merger hereafter provided for, in which Merger Sub would merge with and into Nanotronics and Nanotronics would become a wholly owned subsidiary of Nanogen (the "Merger"); and WHEREAS, it is intended that the Merger qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"): N o w, T h e r e f o r e, in consideration of the premises and of the mutual agreements, provisions and covenants herein contained, the parties hereby agree as follows: ARTICLE I THE MERGER 1.1 The Merger. At the Effective Time (as defined in Section 1.3), upon the terms and subject to the conditions of this Agreement and the Agreement of Merger between Merger Sub and Nanotronics substantially in the form attached hereto as Exhibit 1.1(a) (the "Agreement of Merger"), Merger Sub shall be merged with and into Nanotronics in accordance with the California Corporations Code of the State of California ("California Law"), whereupon the separate existence of Merger Sub shall cease, and Nanotronics shall be the surviving corporation (the "Surviving Corporation"). 1.2 Closing.

As soon as practicable after satisfaction or, to the extent permitted hereunder, waiver of all conditions to the Merger, Nanogen shall file an executed copy of the Agreement of Merger, accompanied by an officers' certificate of each of Nanotronics and Merger Sub, substantially in the form of Exhibits 1.3(a) and 1.3(b), with the Secretary of State of the State of California, and make all other filings or recordings required by the laws of California in connection with the Merger. The Merger shall become effective at such time as the certified copy of the Agreement of Merger is duly filed with the Secretary of State of the State of California (the "Effective Time"). <PAGE> 7 1.4 Corporate Organization. At and after the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises, and be subject to all of the restrictions, disabilities and duties of Nanotronics and Merger Sub, all as provided under California Law. ARTICLE II EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS 2.1 Conversion of Shares of Capital Stock of Nanotronics and Merger Sub. At the Effective Time, by virtue of the Merger and without any action on the part of any holder thereof (subject to the deliveries required to be made by Nanotronics at the Closing as set forth in Section 9.2(a)), the following shall occur: (a) Each share of common stock of Merger Sub, no par value (the "Merger Sub Common Stock"), issued and outstanding immediately prior to the Effective Time, shall be converted into and become one (1) validly issued, fully paid and nonassessable share of Common Stock, no par value, of the Surviving Corporation. (b) Each share of the common stock of Nanotronics, no par value (the "Nanotronics Common Stock"), and each share of the Nanotronics Series A Preferred Stock, no par value (the "Nanotronics Preferred Stock" and, collectively with the Nanotronics Common Stock, the "Nanotronics Capital Stock"), held by Nanotronics as treasury stock immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto. (c) Each share of Nanotronics Preferred Stock outstanding immediately prior to the Effective Time (including any shares of Nanotronics Preferred Stock issued or issuable as a result of the exercise of any Nanotronics Warrant or Nanotronics Option, provided such Nanotronics Warrant or Nanotronics Option, as the case may be, is exercised on or before 5 p.m. California time on the business day immediately preceding the Closing Date, but not including any shares of Nanotronics Preferred Stock outstanding immediately prior to the Effective Time as to which dissenters' rights have been properly asserted under California Law and which are provided for in Section 2.5 hereof) shall be converted into the right to receive .195135267 shares (the "Nanotronics Preferred Exchange Ratio") of the Series D preferred stock, $.001 par value per share (the "Nanogen Series D Preferred Stock") of Nanogen. (d) Each share of Nanotronics Common Stock outstanding immediately prior to the Effective Time (including any shares of Nanotronics Common Stock issued or issuable as a result of the exercise of any Nanotronics Warrant or Nanotronics Option, provided such Nanotronics Warrant or Nanotronics Option, as the case may be, is exercised on or before 5 p.m. California time on the business day immediately preceding the Closing Date, but not including any shares of Nanotronics Common Stock outstanding immediately prior to the Effective Time as to which dissenters' rights have been properly asserted under California Law and which are provided for in Section 2.5 hereof) shall be -2- <PAGE> 8 converted into the right to receive .165296688 shares (the "Nanotronics Common Exchange Ratio") of Nanogen Series D Preferred Stock. The holders of Nanotronics Common Stock and Nanotronics Preferred Stock are hereinafter referred to singularly as a "Nanotronics Shareholder" and collectively as the "Nanotronics Shareholders," and are as set forth on Schedule 2.1-1 attached hereto. The number of shares of Nanogen Series D Preferred Stock to be received by each Nanotronics Shareholder upon consummation of the Merger is set forth next to such Nanotronics Shareholder's name on Schedule 2.1-2 attached hereto. 2.2 Conversion of Nanotronics Options. (a) At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof (subject to the deliveries required to be made by Nanotronics at Closing as set forth in Section 9.2(a)), each unexpired and unexercised option to purchase shares of Nanotronics Capital Stock (individually, a "Nanotronics Option" and collectively the "Nanotronics Options"), as set forth on Schedule 2.2(a) attached hereto, outstanding immediately prior to the Effective Time shall be converted into an option to purchase shares of Nanogen Series D Preferred Stock (a "Converted Nanotronics Option"). Each Nanotronics Option so converted will continue to have, and be subject to, substantially the same terms and conditions as set forth in the documents governing such Nanotronics Option immediately prior to the Effective Time, except that (a) such Converted Nanotronics Option will be exercisable for that number of shares of Nanogen Series D Preferred Stock as is equal to the product of the number of shares of Nanotronics Common Stock or Nanotronics Preferred Stock, as the case may be, that were purchasable under the Nanotronics Option immediately prior to the Effective Time, multiplied by the Nanotronics Preferred Exchange Ratio or the Nanotronics Common Exchange Ratio, as the case may be, in all cases rounded (up if any fraction computed is .50 or greater and down if any fraction computed is less than .50) to the nearest whole number of shares of Nanogen Series D Preferred Stock and (b) the per share exercise price for the Nanogen Series D Preferred Stock issuable upon exercise of such Converted Nanotronics Option will be equal to the quotient obtained by dividing the exercise price per share of the shares of Nanotronics Preferred Stock or Nanotronics Common Stock, as the case may be, at which such Nanotronics Option was exercisable immediately prior to the Effective Time by the Nanotronics Preferred Exchange Ratio or the Nanotronics Common Exchange Ratio, as the case may be, in all cases rounded (up if any fraction computed is .50 of a cent or greater and down if any fraction computed is less than .50 of a cent) to the nearest whole cent. The parties intend that the conversion of the Nanotronics Options hereunder will meet the requirements of Section 424(a) of the Code and this Section 2.2(a) shall be interpreted consistent with such intention. Holders of Nanotronics Options shall not be entitled to acquire shares of Nanotronics Capital Stock after the Merger. (b) The number of shares of Nanogen Series D Preferred Stock to be issued upon the exercise of options to purchase shares of Nanogen Series D Preferred Stock which are the result of the conversions referenced in Section 2.2(a) is set forth next to such holder's name on Schedule 2.1-2 attached hereto. (c) Notwithstanding subsections (a) and (b) of this Section 2.2, the parties hereto expressly acknowledge and agree that the terms of such subsections shall not apply to any holder of any -3- <PAGE> 9 Nanotronics Option which is exercised on or before 5 p.m. on the business day immediately preceding the Closing Date. In such case, such holder shall be treated for all purposes as a holder of Nanotronics Preferred Stock or Nanotronics Common Stock, as the case may be, rather than as a holder of Nanotronics Options. 2.3 Conversion of Nanotronics Warrants. (a) At the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof (subject to the deliveries required to be made by Nanotronics at Closing as set forth in Section 9.2(a)), each unexpired and unexercised warrant to purchase shares of Nanotronics Capital Stock (individually, a "Nanotronics Warrant" and collectively the "Nanotronics Warrants"), as set forth on Schedule 2.2(a) attached hereto, outstanding immediately prior to the Effective Time shall be converted into a warrant to purchase shares of Nanogen Series D Preferred Stock (a "Converted Nanotronics Warrant"). Each Nanotronics Warrant so converted will continue to have, and be subject to, substantially the same terms and conditions as set forth in the documents governing such Nanotronics Warrant immediately prior to the Effective Time, except that (a) such Converted Nanotronics Warrant will be exercisable for that number of shares of Nanogen Series D Preferred Stock as is equal to the product of the number of shares of Nanotronics Preferred Stock or Nanotronics Common Stock, as the case may be, that were purchasable under the Nanotronics Warrant immediately prior to the Effective Time, multiplied by the Nanotronics Preferred Exchange Ratio or the Nanotronics Common Exchange Ratio, as the case may be, in all cases rounded (up if any fraction computed is .50 or greater and down if any fraction computed is less than .50) to the nearest whole number of shares of Nanogen Series D Preferred Stock and (b) the per share exercise price for the Nanogen Series D Preferred Stock issuable upon exercise of such Converted Nanotronics Warrant shall be equal to the quotient obtained by dividing the exercise price per share of the shares of Nanotronics Preferred Stock or the Nanotronics Common Stock, as the case may be, at which such Nanotronics Warrant was exercisable immediately prior to the Effective Time by the Nanotronics Preferred Exchange Ratio or the Nanotronics Common Exchange Ratio, as the case may be, in all cases rounded (up if any fraction computed is .50 cents or greater and down if any fraction computed is less than .50 cents) to the nearest whole cent. Holders of Nanotronics Warrants shall not be entitled to acquire shares of Nanotronics Capital Stock after the Merger. (b) The number of shares of Nanogen Series D Preferred Stock to be issued upon the exercise of warrants to purchase shares of Nanogen Series D Preferred Stock which are the result of the conversions referenced in Section 2.3(a) is set forth next to such holder's name on Schedule 2.1-2 attached hereto. (c) Notwithstanding subsections (a) and (b) of this Section 2.3, the parties hereto expressly acknowledge and agree that the terms of such subsections shall not apply to any holder of any Nanotronics Warrant which is exercised on or before 5 p.m. on the business day immediately preceding the Closing Date. In such case, such holder shall be treated for all purposes as a holder of Nanotronics Preferred Stock or Nanotronics Common Stock, as the case may be, rather than as a holder of Nanotronics Options. 2.4 Conversion of Nanotronics Debt. At the Effective Time, by virtue of the Merger and without any further action on the part of the creditors thereof -4- <PAGE> 10 (subject to the deliveries required to be made by Nanotronics at Closing as set forth in Section 9.2(a)), each creditor of Nanotronics as set forth on Schedule 2.4 attached hereto (the "Exchanging Nanotronics Creditors") shall receive such number of shares of Nanogen Series D Preferred Stock as is set forth on Schedule 2.1-2 as full consideration for cancellation of the debt of Nanotronics held by such Exchanging Nanotronics Creditor (such amount as is set forth next to such Exchanging Nanotronics Creditor's name on Schedule 2.4 attached hereto). 2.5 Dissenting Shares. (a) Notwithstanding Section 2.1, shares of Nanotronics Capital Stock outstanding immediately prior to the Effective Time and held by a holder who has taken all actions as required pursuant to Section 1300 et. seq. of California Law shall not be converted into a right to receive shares of Nanogen Series D Preferred Stock, unless and until such holder withdraws such demand for payment or loses his or her dissenters' rights pursuant to California Law. (b) Nanotronics shall give Nanogen prompt notice of any demands received by Nanotronics for payment for any of its shares, and Nanogen shall have the right to participate in all negotiations and proceedings with respect to such demands. Nanotronics shall not, except with the prior written consent of Nanogen, make any payment with respect to, or settle or offer to settle, any such demands. (c) Each holder of Nanotronics Capital Stock who has complied with the requirements of California Law to properly assert dissenters' rights (and who has not withdrawn his or her demand for payment for his or her shares) shall be paid for his or her shares of Nanotronics Capital Stock in accordance with the procedures set forth under California Law. With respect to any holder of Nanotronics Capital Stock who has properly asserted dissenters' rights at or prior to the Effective Time, but who withdraws his or her request for payment after the Effective Time, each of his or her shares shall, upon the withdrawal of such request, be converted into the right to receive shares of Nanogen Series D Preferred Stock as set forth in Section 2.1 above. Neither of the Nanotronics Common Exchange Ratio nor the Nanotronics Preferred Exchange Ratio shall be adjusted as a result of any assertion of dissenters' rights under this Section. 2.6 Fractional Shares. No fractional shares of Nanogen Series D Preferred Stock shall be issued in the Merger. Any fractional number of shares of Nanogen Series D Preferred Stock to be received by any Nanotronics Shareholder upon computation of the Nanotronics Preferred Exchange Ratio or the Nanotronics Common Exchange Ratio, as the case may be, as applied to such holder's shares of Nanotronics Capital Stock shall be rounded (up if the fraction computed is .50 or greater and down if the fraction computed is less than .50) to the nearest whole number of shares. The number of shares of Nanogen Series D Preferred Stock to be received by each holder of Nanotronics Capital Stock upon consummation of the Merger is set forth in Schedule 2.1-2 attached hereto. -5- <PAGE> 11 ARTICLE III THE SURVIVING CORPORATION 3.1 Certificate of Incorporation.
