14.1.9   The parties shall agree on a date for the transfer of the Inventory,
         which shall not be more than five working days after relevant Local
         Closing. The Inventory shall be shipped CPT (Incoterms 2000) to the
         indicated designated Buyer.

14.2     Effects of Closing. Upon Closing the ownership of the Assets as well as
         the full responsibility for the use of the Assets and the conduct of
         the Business comprising the use of the Assets shall pass from Seller or
         Seller's Affiliate to Buyer or Buyer's Affiliate. Seller shall remain
         exclusively responsible for the conduct of the Business prior to
         Closing (including any consequences therefrom which may appear after
         the Closing). Buyer shall be exclusively responsible for the conduct of
         the Business from Closing. Buyer acknowledges that, as per the Closing,
         Buyer shall be responsible for proper insurance of the product
         liability and other risks relating to the Business. Closing shall not
         prejudice the Buyer and shall not constitute a waiver in relation to
         any claim it may have for damages caused by reason of a breach of any
         of the covenants contained in Article 6. The Closing shall further have
         the other effects provided for in this Agreement.

15       TERMINATION

15.1     Termination. This Agreement or the relevant local Asset Purchase
         Agreement and the transactions contemplated hereby may be terminated at
         any time prior to the date of Closing:

15.1.1   By the mutual written consent of Seller and Buyer;

15.1.2   By either Seller or Buyer if Closing shall not have occurred within
         nine (9) months after the Closing Date as scheduled in Section 14.1.

15.1.3   By Seller, if Buyer culpably fails to either pay the second or third
         down-payment of the Purchase Price on the respective due date, or
         provide RDG on the due date with a perpetual, unrestricted,
         irrevocable, absolute bank guarantee, payable on first demand, covering
         the outstanding amount, which is issued by a major US-American bank
         that is sufficiently acceptable to Seller according to Section 4.3. The
         parties agree that in case of a termination by Seller under this
         Section 15.1.3, the first down-payment of USD 500,000 (five-hundred
         thousand US Dollars) shall remain with Seller and shall not be paid
         back. Accordingly, Buyer hereby waives each and every claim for
         compensation, damages etc. related to a remuneration of the first
         down-payment of USD 500,000 (five-hundred thousand US Dollars).

15.1.4   By either Seller or Buyer if consummation of the transactions
         contemplated hereby shall violate any non-appealable final order,
         decree or judgement of any court or governmental body having competent
         jurisdiction; or


<PAGE>


15.1.5   By either Seller or Buyer if there has been a material violation or
         breach by the other party of any of the representations, warranties or
         covenants contained in this Agreement that has not been waived in
         writing, or if there has been a material failure of satisfaction of a
         condition to the obligations of the other party that has not been
         waived in writing, and such violation, breach, or failure has not been
         cured within sixty (60) days of written notice to the other party.

         It is understood that after a Local Closing has occurred, the local
         Asset Purchase Agreement as well as the part of this Agreement relating
         to it may not be terminated.

15.2     Effect of Termination. If this Agreement is terminated pursuant to
         Sections 15.1.1 or 15.1.3, all obligations of Seller and Buyer under
         this Agreement shall terminate without further liability of Seller or
         Buyer except (a) for the obligations of Buyer and Seller under Sections
         12.2 (Press Releases), 12.4 (Confidentiality) 16 (Indemnification), 18
         (Governing law), 19 (Additional Terms), and (b) that such termination
         shall not constitute a waiver by any party of any claim it may have for
         damages caused by reason of a breach by the other party of a
         representation, warranty, covenant or agreement.

16       INDEMNIFICATION

         indemnified the Buyer and its Affiliates against all actions, claims,
         proceedings, costs and damages and all legal costs or other expenses

         and keep fully indemnified the Seller and its Affiliates against all
         actions, claims, proceedings, costs and damages and all legal costs or

         Affiliates against and agrees to hold Buyer and its Affiliates harmless

         reasonable expenses of investigation and attorneys' fees and expenses
         in connection with any action, suit, or proceeding brought against
         Buyer or its Affiliates) incurred or suffered by Buyer or its

         action, suit or proceeding brought against Seller or its Affiliates)
         incurred or suffered by Seller or its Affiliates arising out of any
         misrepresentation or breach of a warranty or covenant made by Buyer
         herein ("Indemnifiable Claims").

16.4     Limitation of time. Subject to the limitations set forth in this
         Agreement, any claims that a party may have arising out of the other
         party's breach of its representations and warranties hereunder with the
         exception of Seller's claims against Buyer for the Purchase Price
         and/or for being held harmless against third parties' claims with
         regard to patent conflicts according to sections 5.7, 6.7 and 10.3 (to
         which claims said limitation of time shall not apply), shall be
         notified to the other party not later than 1 (one) year following
         Closing (without affecting either party's right to start court
         proceedings thereafter if the notification for the pertaining matter
         has been given prior to the expiration of such 1 (one) year). Seller
         and Buyer agree to use all reasonable efforts to mitigate any loss or
         damage for which they may seek indemnification under this article 16.

16.5     Limitations. With the exception of Seller's claims against Buyer for
         the Purchase Price and/or for being held harmless against third
         parties' claims with regard to patent conflicts according to sections
         5.7, 6.7, and 10.3 (to which claims such limitation shall not apply),
         neither party shall be entitled to indemnification hereunder with
         respect to any indemnifiable claim arising from any breach of this
         Agreement:

         a.       unless and until the aggregate amount of all such claims, each
                  claim not being less than USD 10, 000 (ten thousand USD),
                  exceeds USD 100, 000 (one hundred thousand USD) in which event
                  the other party's liability shall be for the full amount; or

         b.       for an aggregate amount exceeding 10 per cent of the Purchase
                  Price.

         c.       any claims that a party may have arising out of the other
                  party's breach of its representations and warranties hereunder
                  shall be notified to the other party no later than 1 (one)
                  year following Closing (without affecting either party's right
                  to start court proceedings thereafter) if the notification for
                  the pertaining matter has been given prior to the expiration
                  of such one year period).

16.6     Notice. A party seeking indemnification pursuant to Section 16.2 or
         16.3 (an "Indemnified Party") shall give prompt notice to the party
         from whom such indemnification is sought (the "Indemnifying Party") of
         the assertion of any claim, or the commencement of any action, suit or
         proceeding, in respect of which indemnity is or may be sought hereunder
         (whether or not the limits set forth in Section 16.5 have been
         exceeded) and will give the Indemnifying Party such information with
         respect thereto as the Indemnifying Party may reasonably request, but
         failure to give such notice shall not relieve the Indemnifying Party of
         any liability hereunder.


<PAGE>


16.7     Participation in Defence. The Indemnifying Party may, at its expense,
         participate in or assume the defence of any such action, suit or
         proceeding involving a third party. In such case the Indemnified Party
         shall have the right (but not the duty) to participate in the defence
         thereof, and to employ counsel, at its own expense, separate from
         counsel employed by the Indemnifying Party in any such action and to
         participate in the defence thereof. The Indemnifying Party shall be
         liable for the fees and expenses of one firm as counsel (and
         appropriate local counsel) employed by the Indemnified Party if the
         Indemnifying Party has not assumed the defence thereof. Whether or not
         the Indemnifying Party chooses to defend or prosecute any claim
         involving a third party, all the parties hereto shall, and shall cause
         their respective Affiliates to, co-operate in the defence or
         prosecution thereof and shall furnish, or cause to be furnished, such
         records, information and testimony, and attend such conferences,
         discovery proceedings, hearings, trials and appeals, as may be
         reasonably requested in connection therewith.

16.8     Settlements. The Indemnifying Party shall not be liable under this
         section for any settlement effected without its consent of any claim,
         litigation or proceedings in respect of which indemnity may be sought
         hereunder, unless the Indemnifying Party refuses to acknowledge
         liability for indemnification under this Article 16 and/or declines to
         defend the Indemnified Party in such claim, litigation or proceeding.
         Such decision to be notified to the Indemnified Party within 30
         (thirty) days.

16.9     All sums payable by the Indemnifying Party to the Indemnified Party
         under this Article 16 shall be paid free and clear of all deductions or
         withholdings whatsoever, save only as may be required by law.
