               given priority and shall deliver to Sulzer 20 prototype units
               each of each Composite Spacer and priority Processed

CONFIDENTIAL    First Amended Processed Tissue Development and License Agreement
                                                                        --Page 2


               Tissue for testing by Sulzer. In addition, Tutogen shall use its
               best efforts to deliver within 90 days following Sulzer's
               delivery of the final specifications 20 sterile units each of
               each Composite Spacer and priority Processed Tissue.

       2.1.3   Sulzer shall use its best efforts to complete, within 60 days
               following delivery of sterile units of the lumbar and cervical
               Composite Spacers and the priority Processed Tissues to Sulzer,
               its testing and either accept or reject, with explanation, the
               design of the lumbar and cervical Composite Spacers and the
               priority Processed Tissues. In the event that Sulzer rejects the
               design of one or the other Composite Spacer or any of the
               Processed Tissues, the parties shall collaborate on such changes
               to the design as are necessary to make the Composite Spacer or
               Processed Tissue acceptable to Sulzer, and the parties shall
               agree upon a revised development schedule, having in mind the
               goal of an expeditious development of an acceptable Processed
               Tissue.

       2.1.4   Sulzer shall use its best efforts to complete, within 90 days
               following Sulzer's delivery of the final specifications for
               lumbar and cervical spacers, the design and testing of the
               surgical instruments needed for implanting a priority Processed
               Tissue. Sulzer shall use its best efforts to complete, within 150
               days following Sulzer's delivery of the final specifications for
               lumbar and cervical spacers, the design and testing of the
               surgical instruments needed for implanting other Processed
               Tissues, as mutually agreed by the parties.

     Tutogen and Sulzer agree to use their best efforts to complete the
          development of the Composite Spacer and priority Processed Tissues and
          to begin processing of same for use within 210 days following the
          Effective Date of this Agreement.

     Each party shall bear its own expenses in connection with development of
          the Composite Spacer and priority Processed Tissues.

     At such time as Sulzer accepts the design of the lumbar and cervical
          Composite Spacers and the other Processed Tissues, such tissues shall
          become Processed Tissues within the meaning of the U.S. Service
          Agreement and the International Distribution Agreement of even date
          between the parties or their Affiliates.

3.   New Processed Tissue Development and Existing Processed Tissue Improvement

     During the term of this Agreement, the parties anticipate that each party
          will conceive ideas for new Processed Tissues or for improvements to
          existing Processed Tissues. If a party conceiving an idea for a new
          Processed Tissue or for an improvement to an existing Processed Tissue
          wishes to pursue development of that idea, it shall propose
          development of the idea, if at all, solely to the other party. The
          parties shall not disclose ideas for new Processed Tissues or for
          improvements to existing Processed Tissues conceived during the term
          of this Agreement to any Third Party, whether such potential
          disclosure is during the term of this Agreement or after its
          termination, except as provided in this Section 3.2.3.

                                                                        --Page 3


     A party shall propose a development project for an idea by submitting to
          the other party a written description of the proposed new Processed
          Tissue or Processed Tissue improvement. The party receiving the
          proposal shall evaluate the proposal and respond in writing to the
          proposing party within 30 days of receipt of the proposal, either
          accepting or rejecting the proposal.

       3.1.1  The receiving party is under no obligation to accept the proposal
              or otherwise to participate in any project proposed by the other
              party.

       3.1.2  If the receiving party accepts the proposal, the parties shall
              meet and prepare a project plan, agreeing to a development
              schedule and allocating project development responsibilities and
              project costs between the parties. Project responsibilities and
              costs may or may not be allocated equally between the parties.

       3.1.3  If the receiving party rejects the proposal, the proposing party
              shall be free to pursue the project on its own or to collaborate
              on the project with a Third Party; provided that, in so doing the
              proposing party shall not violate or breach any other term of this
              Agreement or any term of the First Amended U.S. Service Agreement,
              the First Amended International Distribution Agreement, or the
              First Amended Option Agreement, all of even date herewith.

     Tutogen shall have the right to process bone tissue for any Processed
         Tissue developed or improved as a result of collaboration between the
         parties under this Section 3.

     Any Processed Tissue developed or improved as a result of collaboration
         between the parties under this Section 3 shall become a "Processed
         Tissue" within the meaning of the First Amended U.S. Service Agreement
         and a "Product" within the meaning of the First Amended International
         Distribution Agreement, both of even date between the parties or their
         Affiliates.


4.   License

     Subject to the right of Tutogen under license agreements with third parties
         to grant sublicenses, Tutogen hereby grants (and will cause its
         Affiliates to grant) to Sulzer and its Affiliates during the term of
         this Agreement an exclusive, worldwide (excluding the United States),
         fully paid-up license or sublicense, as the case may be, under all
         Tutogen Licensed Patents to use and sell the Processed Tissues,
         including, but not limited to, the Composite Spacer. This license
         excludes the United States because Sulzer will not make, use, sell, or
         offer to sell the Processed Tissues in the United States.

     In consideration of the exclusive license granted in this Section 4 to use
         and sell the Composite Spacer, Sulzer agrees to pay Tutogen
         US$1,000,000 by wire transfer on 5 January 2002; provided that, Sulzer
         shall be under no obligation to pay any amount for the license granted
         in this Section 4 unless and until Tutogen shall have delivered at
         least 500 units of Composite Spacer or as many units of Composite
         Spacer as shall have been requested by purchase order for delivery by 1
         January 2002, whichever is less.

5.   Intellectual Property Rights

     5.1  Tutogen and Sulzer each shall own an undivided one-half interest in
          all jointly developed intellectual property, including patent
          applications and patents as to which employees of both parties are
          named as an inventor. Sulzer shall have primary responsibility for
          filing and prosecuting patent applications and maintaining patents on
          jointly developed and owned inventions. Tutogen shall contribute one-
          half of all expenses incurred in connection with such filing,
          prosecution, and maintenance; provided that, Tutogen shall have no
          obligation to reimburse patent-related expenses that it has not first
          approved. In the event that Tutogen refuses to approve any such
          patent-related expenses and that Sulzer elects to incur the expense
          itself, Sulzer shall be the sole owner of any rights resulting
          therefrom. In the event that Sulzer elects not to pursue patent
          protection for any jointly developed and owned invention, Tutogen
          shall have the right, at its sole expense, to pursue patent protection
          for the invention, and Tutogen shall be the sole owner of any rights
          resulting therefrom.

     5.2  In the event that a Third Party is infringing any jointly owned
          intellectual property, Sulzer, at its option, shall have the right to
          bring and control any litigation brought against such Third Party for
          such infringement, and Tutogen shall cooperate with Sulzer. If Sulzer
          elects not to prosecute such litigation, Tutogen shall have the right
          to bring and control such litigation. Both parties shall share equally
          in the expenses and proceeds of such litigation; provided that, if a
          party elects not to contribute its share of the expenses of such
          litigation, it forfeits any right to share in the proceeds of such
          litigation, but shall nonetheless cooperate with the party prosecuting
          such litigation at the reasonable expense of the prosecuting party.

6.   Term and Termination

     6.1  Term. This Agreement shall be effective on the Effective Date and
          ----
          shall remain in effect for an initial term of 10 Contract Years,
          unless sooner terminated according to the terms set forth below. At
          the end of the tenth Contract Year and each succeeding anniversary of
          the Effective Date, this Agreement shall renew automatically for a
          successive one-year term unless one party gives the other party
          written notice of termination at least 12 months in advance of the
          renewal date.

     6.2  Material Breach. If either party is in material breach of any
          ---------------
          obligation in this Agreement, the non-breaching party may give written
          notice to the breaching party of its intention to terminate this
          Agreement, and this Agreement will terminate 60 days after the giving
          of such notice unless during the 60-day period (i) the breach has been
          cured, or (ii) if a breach is incapable of cure within the 60-day
          period, the breaching party has commenced action which is calculated
          to result in a cure of the breach to the reasonable satisfaction of
          the non-breaching party within 120 days after the giving of notice. If
          at the end of the 60-day or 120-day period following a notice of
          termination the parties disagree as to whether the Agreement has
          terminated as provided in this paragraph, the parties shall continue
          to perform under this Agreement until an arbitration tribunal
          constituted as provided in this Agreement has ruled on the matter.

     6.3  Insolvency.  Either party may terminate this Agreement immediately on
          ----------
          delivery of written notice to the other party (i) upon the institution
          by or against such other party of insolvency, receivership, or
          bankruptcy proceedings or any other proceedings for the settlement of
          such party's debts; provided that, with respect to involuntary
          proceedings, such proceedings are not dismissed within 120 days, (ii)
          upon such other party's making an assignment for the benefit of
          creditors, or (iii) upon such other party's dissolution or ceasing to
          do business.

     6.4  Termination Without Cause. Sulzer shall have the right to terminate
          -------------------------
          this Agreement with or without cause at any time on or after January
          15, 2002 provided that Sulzer shall have given Tutogen written notice
          of termination at least 12 months in advance of the termination date.
          Sulzer's notice of termination, if any, shall not relieve Sulzer of
          the obligation thereafter to make the payment set forth in Section 4.2
          above, and Sulzer's termination under this Section 6.4 does not give
          Sulzer any right to recover payments made prior to the effective date
          of termination.

            any such Claim which comes to its attention; (b) allows Sulzer to
            control the defense or settlement of such Claim; (c) does not enter
            into any settlement or compromise of such Claim without the express
            authorization of Sulzer; and (d) reasonably cooperates with Sulzer

            reasonable out-of-pocket expenses associated with such cooperation
            by Tutogen.  Tutogen shall have the right to participate in a non-
            controlling fashion in such legal proceeding at its sole expense.

     7.4.2  No undertaking of Sulzer under this section shall extend to any
            such alleged infringement or violation to the extent that it: (a)
            arises from adherence to design modifications, specifications,
            drawings, or written instructions which Sulzer is directed by
            Tutogen to follow, but only if such alleged infringement or
            violation does not reside in corresponding Processed Tissue of
            Sulzer's design or selection; or (b) arises from adherence to
            instructions to apply Tutogen's trademark, trade name, or other
            company identification; or (c) resides in a Processed Tissue which
            is not of Sulzer's origin and which is furnished by Tutogen to
            Sulzer for use under this Agreement; or (d) relates to use of
            Processed Tissues or other items provided by Sulzer in combination
            with other Processed Tissues or other items, furnished either by
            Sulzer or others, which combination was not installed, recommended
            or otherwise

          will be unenforceable or invalid under any applicable law or be so
          held by applicable court decision, such unenforceability or invalidity
          will not render this Agreement unenforceable or invalid as a whole,
          and, in such event, such provision will be changed and interpreted so
          as best to accomplish the objectives of such unenforceable or invalid
          provision within the limits of applicable law or applicable court
          decisions.

    8.10  Confidentiality. The parties acknowledge that by reason of their
          ---------------
          relationship hereunder, each has had and will continue to have access
          to certain information and materials concerning the other's business,
          plans, customers, technology, and/or Processed Tissues that is
          considered by a party to be confidential ("Confidential Information")
          and of substantial value to that party, which value would be impaired
          if such information were disclosed to third parties. To the extent
          that such information is considered confidential, the disclosing party
          will so indicate to the receiving party, in the case of information in
          documentary or other tangible form, by labeling it conspicuously as
          "CONFIDENTIAL" (or words of similar import) and in the case of
          information conveyed verbally, by identifying same in writing within
          ten days after the first verbal disclosure. Each party agrees that it
          will not use in any way other than as expressly authorized or
          contemplated under this Agreement, nor disclose to any third party,
          any such Confidential Information revealed to it by the other party,
          and will take reasonable precautions (and will cause its Affiliates to
          take reasonable precautions) to protect the confidentiality of such
          information and with no less restrictive precautions than it takes to
          protect its own confidential information. Each party will disclose
          Confidential Information only to those of its employees who have a
          need to know such information. If Confidential Information is required
          to be disclosed in response to an order by a court or other government
          body, or if otherwise required to be disclosed by law, or if necessary
          to establish the rights of a party under this Agreement, the receiving
          party shall use reasonable efforts to provide the disclosing party
          with advance notice of such required disclosure to give the disclosing
          party sufficient time to seek a protective order or other protective
          measures, if any are available, for such Confidential Information.
          "Confidential Information" does not include information, materials,
          technical data or know-how which: (i) is rightfully in the possession
          of the receiving party at the time of disclosure as shown by the
          receiving party's files and records immediately prior to the time of
          disclosure; (ii) prior to or after the time of disclosure becomes part
          of the public knowledge or literature, not as a result of any inaction
          or action of the receiving party; (iii) is independently developed by
          a party without the use of any Confidential Information of the other
          parties; (iv) is obtained from any third party who is authorized to
          disclose such data and information without obligation of
          confidentiality, or (v) is approved for release by the disclosing
          party. This Section 8.10 shall survive termination of this Agreement
          for a period of two years.

    8.11  Public Relations And Announcements.  The parties shall agree upon and
          ----------------------------------
          issue a press release upon the signing of this Agreement. No party
          shall issue a press release or any other published statement that
          refers to another party, its Affiliates or the other party's products
          without first obtaining the agreement of such other party as to the
          form and content of the statement, which approval shall be timely and
          not unreasonably withheld.

       In witness whereof, the parties have each caused this Agreement to be
signed and delivered by their duly authorized representatives on the dates set
forth below in duplicate, each of which will be treated for all purposes as an
original.
