1.3 The aforementioned shares represent 100% of the totally paid up and outstanding share capital of ADL. 1.4 ADL is currently managed by a team made up of Franz Maier, Eva Heidt and Joachim Hevler. 1.5 MATRITECH, Inc., a corporation organized under the laws of the State of Delaware, USA (the "PURCHASER" or "MATRITECH") wishes to acquire all the shares referred to in Section 1.2 hereof (the "SHARES") from the Sellers by means of this purchase agreement (the "PURCHASE AGREEMENT") pursuant to the terms and conditions hereof. 2 INTERPRETATION 2.1 In this Purchase Agreement (including the Introduction and the Schedules), the following expressions shall have the following meanings: Business Days means German business days BGB means the German Civil Code HGB means the German Commercial Code Domestic means the Federal Republic of Germany 7 Purchase Agreement ADL GmbH Page 7 3 LIABILITY 3.1 The Sellers shall assume collective liability for their respective obligations incurred under the terms of this Purchase Agreement according to Sections 421 ff. BGB. NOW, THEREFORE, in consideration of the mutual covenants, benefits, conditions and agreements set forth herein, it is hereby agreed as follows: ARTICLE II ---------- SALE AND PURCHASE 4 SALE AND ASSIGNMENT, EFFECTIVE DATE 4.1 The Sellers hereby sell their respective Shares as set out in Section 1.2. to the Purchaser who agrees to hereby purchase the respective Shares. The Sellers hereby assign their respective Shares to the Purchaser as of 12 pm today (the "EFFECTIVE DATE"). The Purchaser hereby assumes the respective Shares (Annahme der Abtretung) with effect from the Effective Date. For the avoidance of doubt: Among other things, all issued share capital and additional equity shall thereby be transferred to the Purchasers. 4.2 Each Seller hereby undertakes with the Purchaser at the request of the Purchaser to do or procure to be done all such further acts and things and execute or procure to be executed all such further deeds and documents as may be necessary or desirable fully and effectively to vest in the Purchaser the legal and beneficial ownership of the Shares and the benefits of this Purchase Agreement and any document specified herein and, pending such vesting, a Seller shall hold such Shares and benefits in trust 8 Purchase Agreement ADL GmbH Page 8 for the Purchaser and shall receive all monies in connection therewith as trustee of the Purchaser and shall account to the Purchaser forthwith on receipt. ARTICLE III ----------- ACQUISITION CONSIDERATION ------------------------- 5 CONSIDERATION AND CALL OPTION 5.1. In consideration for the sale and assignment of the Shares to the Purchaser, the Purchaser shall procure the issue to the Sellers in proportion of their respective shareholdings in ADL of that number of shares of the non-registered Common Stock of MATRITECH, $.01 par value (the "MATRITECH STOCK"), valued at the average of the quoted closing prices from 18 May 2000 through 16 June 2000 on the NASDAQ Stock Market (the "MARKET PRICE") at DM240,000 in aggregate (the "INITIAL CONSIDERATION"). The aggregate Consideration shall be split so that the Sellers receive MATRITECH Stock in the value of Franz Maier 144,000DM Eva Heidt 48,000DM Joachim Hevler 48,000DM. At the Effective Date the Purchaser shall pay to the Sellers the Initial Consideration by means of delivery of the respective share certificates to the Sellers. For the purposes of establishing the value of the Consideration in US dollars, the exchange rate is deemed to be $1 = DM2.0532, being the dollar spot rate published in the Financial Times newspaper of 16 June 2000. 9 Purchase Agreement ADL GmbH Page 9 5.1.1 A second payment (the "ADDITIONAL CONSIDERATION") will be made 60 days after the completion of a financial audit of ADL for the fiscal year ended December 31, 2000. This payment will be calculated by multiplying 20% by the increase in year 2000 revenues over year 1999 revenues of DM3,580,000,--. If year 2000 revenues exceed DM4,395,000,-- the amount of the excess over 4,395,000,-- will be multiplied by 40% and this result will be added to the Additional Consideration. 5.1.2 This Additional Consideration, if any, shall be paid to the Sellers in shares of MATRITECH Stock the number of which shares will be determined by dividing the payment amount by the same Market Price used to calculate the payment in Section 5.1, pro rata in the same proportions as the Initial Consideration is shared among the Sellers. The Initial Consideration and the Additional Consideration are collectively referred to as the "CONSIDERATION." The Sellers agree that they will not sell, assign, transfer, pledge or otherwise dispose of any of the shares of MATRITECH Stock received by them under this Purchase Agreement prior to the first anniversary of the Effective Date or while any of such shares are subject to the Call Option described in Section 5.2. Thereafter the Sellers agree that they will only sell or dispose of such shares in accordance with the terms of this Purchase Agreement and applicable securities laws. 5.2. The Sellers - each separately - herewith grant the Purchaser a call option (the "CALL OPTION") in the event of them leaving ADL, under the circumstances described in Section 5.3, as follows: Conditionally subsequent to and subject to (unter der aufschiebenden Bedingung) the occurrence of a Trigger Event (as defined below) each Seller herewith offers for sale to the Purchaser all or part of his MATRITECH Stock received as the Consideration under the following terms: (i) In the event that a Trigger Event occurs with respect to a Seller on or before the first anniversary of the Effective Date, the Call Option 10 Purchase Agreement ADL GmbH Page 10 will cover all MATRITECH Stock received by that Seller as Consideration at a price of 5% of the quoted price of such MATRITECH Stock on the NASDAQ Stock Market at the close of business on the day the Trigger Event occurs or the next business day, if such Trigger Event does not occur on a business day; (ii) In the event that a Trigger Event occurs with respect to a Seller after the first anniversary but on or before the second anniversary of the Effective Date, the Call Option will cover 67% of all MATRITECH Stock received by that Seller as Consideration at a price of 5% of the quoted price of such MATRITECH stock on the NASDAQ Stock Market at the close of business on the day the Trigger Event occurs or the next business day, if such Trigger Event does not occur on a business day; (iii) In the event that a Trigger Event occurs with respect to a Seller after the second anniversary but on or before the third anniversary of the Effective Date, 33% of all MATRITECH Stock received as Consideration by that Seller at a price of 5% of the quoted price of such MATRITECH shares on the NASDAQ Stock Market at the close of business on the day the Trigger event occurs or the next business day, if such Trigger Event does not occur on a business day. All such offers may be accepted by the Purchaser within 4 weeks by written notice to the Sellers who is subject to the Trigger Event separately and any sale shall be completed on receipt of such notice. The Seller shall take all such actions as necessary and or appropriate to transfer title in such shares to the Purchaser. The Purchaser shall be entitled, at its sole discretion, to provide any consideration due to any seller under the Call Option either in kind by means of delivering MATRITECH stock or by making payments in cash. MATRITECH stock is to be valued as provided for in 5.2. (i - iii). The exchange rate for cash shall be the US dollar spot exchange rate published in the Financial Times newspaper of the day the Trigger event occurs or of the next business day if such Trigger event does not occur on a business day. 11 Purchase Agreement ADL GmbH Page 11 If a Seller becomes obligated to sell any MATRITECH Stock to the Purchaser under the Call Option and fails to deliver such MATRITECH Stock in accordance with the terms of this Purchase Agreement, the Purchaser may, at its option, in addition to all other remedies it may have, send to the Seller the purchase price for such MATRITECH Stock as is herein specified. Thereupon, MATRITECH upon written notice to the Seller, (a) shall cancel on its books the certificate or certificates representing the MATRITECH Stock to be sold under the Call Option and (b) shall issue, in lieu thereof, a new certificate or certificates representing such MATRITECH Stock, and thereupon all of the Seller's rights in and to such MATRITECH Stock shall terminate. The obligations of the Sellers to transfer title in shares and/or cash to the Purchaser and the obligations of the Purchaser to transfer title in shares and/or cash to the Sellers as provided in this clause 5.2. shall be due 2 weeks following the receipt of the exercise notice by the Sellers. In the event of a Call Option being exercised on the MATRITECH Stock held by a single Seller, the shareholdings of the remaining two Sellers shall be unaffected. This Call Option shall expire in its entirety on the first business day following the third anniversary of the Effective Date. 5.3. A Trigger Event for the purpose of this Purchase Agreement shall be deemed to occur: If a Seller ceases to work for or provide services to ADL be it as an employee, managing director, consultant or in any other comparable capacity if (1) he leaves of his own accord without the consent of the Purchaser before the third anniversary of the Effective Date or (2) ADL terminates the contract or otherwise dismisses such Seller with good legal reason (wirksame Kundigung) such termination or dismissal becoming effective before the third anniversary of the Effective Date. For the avoidance of doubt: In case the shareholders of the Company resolve to wind up the ADL for other reasons than its insolvency, or in case of an insolvency caused by 12 Purchase Agreement ADL GmbH Page 12 the withdrawal of loans or other finance instruments by the Purchaser before maturity or in violations of a financing agreement, or in case that ADL closes down its business (Aufgabe des Geschaftsbetriebs) and the Sellers leave ADL because of such events before the third anniversary of this Agreement, such events shall not be deemed to be a Trigger Event.
