Schumacher (the "Stockholder"), and G&G Diagnostics Limited Partnership I and G&G Diagnostics Limited Partnership II (each an "Investor" and collectively the "Investors"). WHEREAS, the Stockholder is the holder of an aggregate of 82,500 shares of common stock, $.01 par value, of the Company (the "Common Stock"); WHEREAS, the Investors have acquired shares of Common Stock of the Company pursuant to the terms of a Common Stock Purchase Agreement dated June 5, 1990 as amended on the date hereof between the Company and the Investors (the "Purchase Agreement"); and WHEREAS, it is a condition to the obligations of the Investors under Amendment No. 1 to the Purchase Agreement that this Agreement be executed by the parties hereto, and the parties are willing to execute this Agreement and to be bound by the provisions hereof; NOW, THEREFORE, in consideration of the foregoing, the agreements set forth below, and the parties' desire to provide for continuity of ownership of the Company to further the interests of the Company and its present and future stockholders, the parties hereby agree with each other as follows: 1. Certain Defined Terms. As used in this Agreement, the following terms shall have the following respective meanings: (a) "Stock" shall mean and include all shares of Common Stock, and all other securities of the Company which may be issued in exchange for or in respect of shares of Common Stock (whether by way of stock split, stock dividend, combination, reclassification, reorganization, or any other means). (b) "Shares" shall mean and include all shares of Stock now owned or hereafter acquired by either the Stockholder or the Investor. (c) "Effective Date" shall have the meaning set forth in Section 5.23 of the Purchase Agreement. - 2 - 2. Prohibited Transfers. After the Effective Date, the Stockholder shall not sell, assign, transfer, pledge, hypothecate, mortgage, encumber or dispose of all or any of his Shares except to the Company or as expressly provided in this Agreement. Notwithstanding the foregoing, the Stockholder may transfer all or any of his Shares (i) by way of gift to any member of his family or to any trust for the benefit of any such family member or the Stockholder, provided that any such transferee shall agree in writing with the Company and the Investor, as a condition to such transfer, to be bound by all of the provisions of this Agreement to the same extent as if such transferee were the Stockholder, (ii) by will or the laws of descent and distribution, in which event each such transferee shall be bound by all of the provisions of this Agreement to the same extent as if such transferee were the Stockholder. Notwithstanding Section 3 below the Stockholder may pledge not more than 50% of the Shares held by him for purposes of obtaining personal financing. As used herein, the word "family" shall include any spouse, lineal ancestor or descendant, brother or sister, niece or nephew. 3. Right of First Refusal on Dispositions. --------------------------------------- (a) If at any time after the Effective Date the Stockholder desires to sell for cash or cash equivalents all or any part of his Shares pursuant to a bona fide offer from a third party (the "Proposed Transferee"), the Stockholder shall submit a written offer (the "Offer") to sell such Shares (the "Offered Shares") to the Investor on terms and conditions, including price, not less favorable to the Investors than those on which the Stockholder proposes to sell such Offered Shares to the Proposed Transferee. The Offer shall disclose the identity of the Proposed Transferee, the Offered Shares proposed to be sold, the total number of Shares owned by the Stockholder, the terms and conditions, including price, of the proposed sale, and any other material facts relating to the proposed sale. The Offer shall further state that the Investors may acquire, in accordance with the provisions of this Agreement, all, but not less than all, of the Offered Shares for the price and upon the other terms and conditions, including deferred payment (if applicable), set forth therein. (b) The Investors shall have the absolute right to purchase all of the Offered Shares. To the extent that the Investors as a group may purchase all, but not less than all, of the Offered Shares, the Investors may determine among themselves the number of such Offered Shares to be purchased by each Investor. (c) If an Investor desires to purchase all or any part of the Offered Shares, said Investor shall communicate in writing its election to purchase to the Stockholder, which communication shall state the number of Offered Shares said Investor desires to -3- purchase and shall be delivered in person or mailed to the Stockholder at the address set forth in accordance with Section 11 below within thirty days of the date the Offer was made. Such communication shall, when taken in conjunction with the Offer, be deemed to constitute a valid, legally binding and enforceable agreement for the sale and purchase of such Offered Shares. Sales of the Offered Shares to be sold to purchasing Investors pursuant to this Section 3 shall be made at the offices of the Company on the 45th day following the date the Offer was made (or if such 45th day is not a business day, then on the next succeeding business day). Such sales shall be effected by the Stockholder's delivery to each purchasing Investor of a certificate or certificates evidencing the Offered Shares to be purchased by it, duly endorsed for transfer to such purchasing Investor, against payment to the Stockholder of the purchase price therefor by such purchasing Investor. (d) If the Investors do not purchase all of the Offered Shares, the Offered Shares not so purchased may be sold by the Stockholder at any time within 90 days after the date the Offer was made, subject to the provisions of Sections 4, 5 and 6. Any such sale shall be to the Proposed Transferee, at not less than the price and upon other terms and conditions, if any, not more favorable to the Proposed Transferee than those specified in the Offer. Any Offered Shares not sold within such 90-day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 3. If Offered Shares are sold pursuant to this Section 3 to any purchaser who is not a party to this Agreement, the Offered Shares so sold shall no longer be subject to any of the restrictions imposed by this Agreement. (e) The Investors' right of first refusal provided in this Section 3 shall not apply with respect to sales of Shares to the Company. 4. Right of Participation in Sales. -------------------------------- (a) If at any time after the Effective Date the Stockholder desires to sell all or any part of the Shares owned by him to any person or entity other than one or more of the Investors (the "Purchaser"), each of the Investors shall have the right to sell to the Purchaser, as a condition to such sale by the Stockholder, at the same price per share and on the same terms and conditions as involved in such sale by the Stockholder, the same percentage of the Shares owned by such Investor as the Shares to be sold by the Stockholder to the Purchaser represents with respect to the Shares owned by the Stockholder immediately prior to the sale of any of his Shares to the Purchaser. For the purposes of this Section 4, all of the stock which an Investor has the right to acquire from the Company upon the conversion, exercise or exchange of any of the securities of the Company then owned by such Investor. - 4 - (b) Each Investor wishing to so participate in any sale under this Section 4 it shall notify the Stockholder in writing of such intention as soon as practicable after receipt of the Offer made pursuant to Section 3, and in any event within twenty days after the date the Offer was made. Such notification shall be delivered in person or mailed to such Stockholder at the address set forth in accordance with Section 11 below. (c) The Stockholder and each participating Investor shall sell to the Purchaser all, or at the option of the Purchaser, any part of the Shares proposed to be sold by them at not less than the price and upon other terms and conditions, if any, not more favorable to the Purchaser than those in the Offer provided by the Stockholder under Section 3 above; provided, however, that any purchase of less than all of such Shares by the Purchaser shall be made from the Stockholder and each participating Investor pro rata based upon the relative amount of the Shares that the Stockholder and each participating Investor are otherwise entitled to sell pursuant to Section 4(a). (d) Any Shares sold by the Stockholder pursuant to this Section 4 shall no longer be subject to the restrictions imposed by this Agreement and any Shares sold by a participating Investor pursuant to this Section 4 shall no longer be entitled to the benefits conferred by this Agreement. (e) The Investors' right to participate in sales pursuant to this Section 4 shall not apply with respect to sales of Shares to the Company. 5. Election of Directors. After the Effective Date, the Stockholder agrees to vote all his Shares at all elections of directors of the Company so that the Board of Directors of the Company shall consist of six members.

Sales Before the Effective Date. If the Stockholder shall sell, assign, transfer or otherwise dispose of all or any of his Shares prior to the Effective Date to any Purchaser who is not a party to this Agreement the Shares so sold shall continue to be subject to the restrictions of this Agreement (including but not limited to the restrictions on transfer in Sections 2, 3, and 4 and the voting provisions of Section 5). 7.

Failure to Deliver Shares. If the Stockholder becomes obligated to sell any Shares to an Investor or the Company under this Agreement and fails to deliver such Shares in accordance with the terms of this Agreement, such Investor or the Company, as the case may be, may, at its option, in addition to all other remedies it may have, send to the Stockholder the purchase price for such Shares as is herein specified. Thereupon, the Company upon written notice to the Stockholder, (a) shall cancel on its books the certificate or certificates representing the Shares to be sold and (b) shall issue, in lieu thereof, in the name of such Investor or the Company, as the case may be, a new certificate or certificates representing such Shares, and thereupon all of the Stockholder's rights in and to such Shares shall terminate. 9. Specific Enforcement. The Stockholder expressly agrees that the Investors and the Company will be irreparably damaged if this Agreement is not specifically enforced.

To the extent any term or other provision of any other indenture, agreement or instrument by which any party hereto is bound conflicts with this Agreement, this Agreement shall have precedence over such conflicting term or provision. - 6 - 13. Governing Law; Successors and Assigns.

Severability. If any provision of this Agreement shall be held to be illegal, invalid or unenforceable, such illegality, invalidity or unenforceability shall attach only to such provision and shall not in any manner affect or render illegal, invalid or unenforceable any other provision of this Agreement, and this Agreement shall be carried out as if any such illegal, invalid or unenforceable provision were not contained herein. 16. Captions. Captions are for convenience only and are not deemed to be part of this Agreement. 17. Continuation of Employment.
