3.4      The number of shares to be transferred as consideration pursuant
         to Section 3.2 item b) shall be equivalent to the quotient, in US 
         dollars, of 1,250,000 deutsche marks at the average price between the

         [Federal Republic of Germany] on October 23, 1998 (hereinafter
         referred to as the "average foreign exchange rate"), divided by the
         average sale price, in US dollars, as defined below. The "average

         USA (hereinafter referred to as the "banking day") in the last four
         months preceding October 24, 1998. Subsequently, the result of the

         days in the last four months preceding October 24, 1998.

                                      -5-

3.5      The Seller undertakes not to sell or transfer the shares acquired in
         accordance with Section 3.2 b) within six months of the deadline.


3.6      Subject to the limitations set forth in sentence 3 [of this paragraph]

         fourth anniversary of the deadline, and if the market price achieved
         by the Seller for a share at the time he sells the shares on Nasdaq
         in New York, New York, USA (hereinafter referred to as the "market
         price") is lower than the average sale price (Section 3.4), the Buyer
         shall transfer to the Seller a specific number of new shares so that
         the result of multiplying the current market price with the total
         number of shares that were transferred to the Seller pursuant to
         Section 3.2 item b) and Section 3.6 is equal to the equivalent value
         in US dollars of 1,250,000 deutsche marks at the average foreign
         exchange rate (Section 3.4). If the result of the multiplication set
         forth in the preceding sentence calls for the transfer of fractions
         of one share of the Buyer's common stock to the Seller, the number of
         shares shall be rounded off to the next higher full number. The
         maximum number of shares to be transferred in accordance with Section
         3.2 item b) and Section 3.6 shall be computed on the basis of the
         following equation:

                                      -6-





Maximum number =

Equivalent value in US$ of DM 1,250,000 at the average foreign
exchange rate (Section 3.4)

         one share of the Buyer's common stock on Nasdaq on October 23, 1998,

         maximum number of shares to be transferred in accordance with Section
         3.2 item b) and Section 3.6 would be 115,918.


3.7      Any and all payments and/or transfers to the Seller in accordance
         with Section 3 shall be made to the bank account and/or the securities
         account of the Seller with Sparkasse Dingolfing, bank routing number

                                 LEGAL RECOURSE

6.1      If one or several of the covenants and warranties made in the present
         agreement or any of the duties undertaken herein do not apply or are
         not satisfied, the Buyer shall have the right, at its discretion,

         a)   to demand that the Buyer and the companies be placed in a
              situation equivalent to the situation that would exist if the
              respective covenant or warranty would apply or if the respective
              duty had been satisfied;

         and/or

         b)   to demand compensation for any damages incurred, now or in the
              future, by the Buyer and/or the companies;

         and/or

         c)   to claim a reduction of the purchase price, in deviation from
              Section 472 BGB, in an amount that equals the reduction in assets
              incurred by the Buyer and/or the companies.

6.2      If damages incurred on one level are reflected on another level, any
         claims for compensation of such damages may be made only once.

6.3      Notwithstanding any other provisions of the present agreement, the
         Seller undertakes to hold the Buyer and, if requested by the latter,
         the companies harmless from any and all tax liabilities and 


                                     -14-


         other disadvantages related thereto, if any, as of the respective
         date on which such liabilities are due and payable, which affect the
         tax periods up to the deadline and which are not covered by debit
         items in both the annual and interim financial statements. This shall
         include interest and surcharges, a well as disadvantages resulting
         from a restructuring, if any, of the equity that may be utilized for
         tax purposes in the sense of Sections 28, 29 KStG
         [Korperschaftssteuergesetz - corporate tax law]. In this connection,
         the Buyer shall have all rights pursuant to Section 6.1. If tax
         audits or subsequent assessments result in additional tax liabilities
         to be paid by the companies, any advantages and disadvantages
         resulting from tax savings which, in turn, stem from periodic
         deferrals or subsequent capitalization shall be offset only at the
         time at which the tax savings actually affect the companies or their
         legal successors.

6.4      Any claims pursuant to Section 6 shall be subject to the following 
         statute of limitations:

         a)   With the exception of claims for damages due to legal defects
              (Section 5.2.1), environmental claims (Section 5.2.9), and
              product liability (Section 5.2.15), as well as claims for damages
              or reimbursement of tax and social security liabilities (Section
              5.2.13 and Section 6.3), all claims under Section 6.1 shall
              expire on December 31, 2000;

         b)   The statutory statute of limitations shall apply to claims for
              legal defects (Section 5.2.1);

         c)   Claims for damages in connection with environmental liabilities
              (Section 5.2.9) shall expire on December 31, 2003; and

         d)   Claims resulting from breaches of covenants and warranties
              concerning tax and social security liabilities (Section 5.2.13
              and Section 6.3) shall expire within six months of the
              effectiveness or nonappealability of the respective tax and/or
              social security assessments.

6.5      The statute of limitations concerning claims, if any, made by the
         Buyer shall be interrupted by a written demand for performance or a
         written notification of defect analogous to the requirements set forth
         in Section 202 BGB, in connection with Section 205 BGB, with the
         proviso that in order to preserve its claims the Buyer must assert
         its claims in court within 12 months of the date of the demand for
         performance or the notification of defect, however, not prior to the
         expiration of the respective statute of limitations pursuant to
         Section 6.4.

6.6      Articles 460 and 464 BGB, as well as Sections 377 ff. HGB
         [Handelsgesetzbuch - commercial code] shall not apply.

6.7      Claims on the part of the Buyer under Section 6 shall be valid only if
         the amount or the value of the claim, or the sum total of all its
         claims, equals at least 50,000 deutsche marks. If this limit is
         exceeded, the full amount shall be due and payable or reimbursed in
         each case. As far as demands for taxes or social security taxes are
         concerned, in this connection the total of any and all subsequent
         assessments shall apply.

6.8      If the liability of the Seller is limited to the best of his knowledge
         or to his actual knowledge, he shall nevertheless be liable for due
         diligence pursuant to Section 43 para 1 GmbHG. The Seller shall be 
         credited with having acted with the best knowledge or actual
         knowledge of a managing director and Prokuristen [persons with
         special power of attorney].

         such information is required for safeguarding the interests of the
         companies or the Buyer.

7.2      If the companies are audited after the deadline by tax authorities
         with regard to assessment periods preceding the deadline, the Seller
         shall be given the opportunity to have a representative, who is
         subject to confidentiality agreements, participate in the audit,
         especially in the final discussions pertaining thereto. Any and all
         information required for safeguarding the interests of the Seller
         shall be provided to the latter, at his request and expense. In
         addition, the Seller may request, also at his expense, that the
         company affected by any such tax assessment avail itself of any
         recourse available to it. The respective proceedings shall be carried
         out by the Seller at his expense.


                                   SECTION 8

         companies associated with him shall engage in direct or indirect
         competition with the companies and that he or companies associated
         with him shall not establish, participate in, consult, or otherwise
         support a company, either directly or indirectly, that competes with
         the companies' current business activities. In geographical terms, the
         prohibition of competition shall be limited to the areas in which the
         companies currently do business. This provision shall not apply to
         investments by the Seller in companies that are traded on stock
         exchanges, provided such investments amount to less than two percent
         of the share capital of such publicly traded company.

8.2      If the Seller violates the prohibition of competition set forth above,
         he shall be liable for a fine of 500,000 deutsche marks for each
         violation. In the event of continued violation of the prohibition of
         competition, each week of violation shall be considered a separate
         instance of such violation. Any right to claim damages resulting from
         such violation or claims under the performance guaranty shall be
         unaffected thereby.

         undertook relative to a third party (hereinafter referred to as the
         "lessor"), which has rented office space to the KG at Hauptstrasse 32,
         85457 Worth, Wilfing, [Federal Republic of Germany], under a lease
         dated 16/10/96 [change initialed], to cover the liabilities incurred
         by the KG under such lease. The parties to this agreement stipulate

         to the best of their abilities, to have the Seller released from his
         liability toward the lessor under the guaranty. If the lessor refuses
         to release the Seller from his guaranty obligations, the Buyer
         declares, subject to the condition precedent of the transfer in rem
         of the shares to the Buyer, that it shall hold the Seller harmless
         from any claims under such guaranty. The Buyer shall not have any
         offset or retention rights whatsoever relative to the Seller's right
         to be held harmless.
