          -----------
          continuing quarterly thereafter, Sulzer shall provide Tutogen, no
          later than 15 days prior to each calendar quarter, with a rolling
          monthly forecast of sales of the Products for the succeeding 12
          months. Sulzer's forecasts shall specify the anticipated sales by
          Product, by Sub-Territory, and by month. Sulzer shall incur no
          liability to Tutogen in the event that actual sales of the Products
          differ from Sulzer's forecasts.

     3.5  Minimum Annual Product Sales. As consideration for the exclusive right

          to sell the Products in the Territory, commencing with the ninth month

          third party, on an exclusive or a non-exclusive basis, to sell the
          Product in that Sub-Territory only and for the Field of Use. Tutogen
          shall exercise its option, if at all, by giving Sulzer written notice
          of its election no later than 60 days following the end of the
          Contract Year in question.

          ---------------

4.   Tutogen's Obligations

     4.1  Product Supply. Tutogen agrees to use its best efforts to acquire
          --------------

          the Tutoplast(R) process according to Sulzer's forecasts for demand
          for Products, manufacture the Products, and sell the Products to
          Sulzer pursuant to purchase orders issued by Sulzer at the transfer
          prices to which the parties shall agree and list in Schedule C
          attached hereto. Sulzer shall pay the transfer price to Tutogen within
          45 days from the date of Tutogen's invoice. In no event shall Tutogen
          or an Affiliate of Tutogen or a Permitted Successor of Tutogen during
          the term of this Agreement supply allograft bone tissue, whether
          processed or unprocessed, to a Third Party for further distribution in
          the Territory for the Field of Use; provided that, Tutogen shall be
          permitted to deliver unprocessed allograft bone tissue

CONFIDENTIAL         First Amended International Distribution Agreement - Page 3


          pursuant to the RTI Agreement so long as Tutogen's supply of allograft
          bone tissue exceeds the demand for Products under this Agreement.

     4.2  Termination of Distribution Contracts. Tutogen shall terminate the
          -------------------------------------
          right of its existing distributors, excluding Canada, Italy, Spain,
          and Turkey, to distribute the Products for the Field of Use as soon as
          possible after the Effective Date according to the terms of existing
          distribution agreements, if any. Schedule D sets forth the dates by
          which termination of Tutogen's existing distributors, excluding
          Canada, Italy, Spain, and Turkey, shall be effective. Sulzer shall
          have an immediate nonexclusive right to sell the Products for the
          Field of Use in all countries listed in Schedule D, pending
          termination of existing distribution agreements, to the extent
          permissible under existing distribution agreements. The parties shall
          consult regarding Tutogen's distributors in Canada, Italy, Spain, and
          Turkey, which together represent a significant portion of Tutogen's
          current revenue from sales of the Products, and Tutogen shall use its
          best efforts to accommodate Sulzer's desired distribution in those
          countries and terminate Tutogen's existing distributors, if so
          determined by Sulzer after consultation. Tutogen agrees to insure that
          any substantial inventory of the Products held by the distributors at
          the time of their termination is either returned to Tutogen or
          transferred to Sulzer.


5.   Regulatory Matters

     5.1  Import Compliance. Tutogen agrees to comply with and maintain
          -----------------
          compliance with all governmental rules, regulations, statutes, and
          other laws of any kind necessary to acquire xenograft and donor
          allograft tissue, manufacture the Products, and deliver the Products
          to Sulzer within the Territory.

     5.2  Regulatory Responsibilities. The parties understand that as of the
          ---------------------------
          Effective Date of this Agreement, the Products are regulated by
          governmental authorities in most of the countries in the Territory,
          and Tutogen has obtained approvals from such regulatory authorities to
          sell many of the Products in such countries. As to Products for which
          Tutogen has not obtained regulatory approval in a particular country
          as of the Effective Date, or Products that first become regulated in a
          particular country after the Effective Date, Sulzer, at its own cost,
          shall be responsible for obtaining regulatory approval for such
          Product in such country, as an agent for Tutogen; provided that,
          Sulzer may elect upon written inquiry from Tutogen to remove such
          Product from Schedule A (for purposes only of the particular country)
          rather than to seek regulatory approval therefor. In the event that
          Sulzer elects to remove a regulated Product from Schedule A (as to a
          particular country), Tutogen shall have the right to seek regulatory
          approval therefor at its own expense and to sell such Product in the
          particular country without obligation to Sulzer under this Agreement.

     5.4  Clinical Trial Costs. Tutogen agrees to bear all costs related to pre-
          --------------------
          clinical trials in support of Sulzer's efforts to obtain regulatory
          approval for a Product. Sulzer agrees to bear all costs related to
          clinical trials and filing for, obtaining, and maintaining the
          regulatory approval.

     5.5  Ownership of Approvals. Tutogen shall be the record owner of all
          ----------------------
          regulatory approvals to sell Products in the Territory and for the
          Field of Use.

CONFIDENTIAL         First Amended International Distribution Agreement - Page 4


6.   Trademark License and Product Labeling

     6.1  License Grant. Tutogen grants Sulzer a nonexclusive license under
          -------------
          Tutogen's trademarks, Tutoplast(R), Tutobone(R), and Spline Line(R),
          to use the trademarks solely in connection with the Products and the
          marketing thereof within the Territory for the Field of Use.

     6.2  Publication Approvals. Sulzer shall provide Tutogen with samples of
          ---------------------
          all marketing and other printed materials utilizing a trademark of
          Tutogen in advance of publication of the same. Tutogen shall be deemed
          to have approved such samples for actual use unless it objects in
          writing within 10 business days following Sulzer's delivery of same.

     6.3  Labeling. Tutogen agrees to include the trademarks of Sulzer on
          --------
          Product labels in a manner mutually agreeable to the parties.


7.   Term and Termination

     7.1  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 in this
          Agreement. 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.

     7.2  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.

     7.3  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.

     7.4  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

CONFIDENTIAL         First Amended International Distribution Agreement - Page 5


          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 payments set forth in Section 2.2 above, and
          Sulzer's termination under this Section 7.4 does not give Sulzer any
          right to recover payments made prior to the effective date of
          termination. In the event that Sulzer shall terminate this Agreement
          without cause as provided in this Section 7.4, neither Sulzer nor any
          Affiliate of Sulzer shall for a period of one year following the
          effective date of termination enter into an agreement, either directly
          or indirectly, to own, operate, advise, or have any interest in any
          business relating to the Products in the Territory for the Field of
          Use.

     7.5  Reimbursement of Regulatory Expenses. In the event that the Agreement
          ------------------------------------
          terminates (i) by reason of Tutogen's notice of termination under
          Section 7.1, or (ii) by reason of Tutogen's material breach under
          Section 7.2, then Tutogen shall be obligated to reimburse Sulzer's
          out-of-pocket expenditures, or a portion thereof as determined in this
          Section 7.5, in obtaining or attempting to obtain regulatory approval
          for Products under Section 5.2, including the out-of-pocket cost of
          all pre-clinical, if any, and clinical trials and other expenses
          directly related to the regulatory approval process (the "Clinical
          Expenses"). For each Product as to which Sulzer has obtained or
          attempted to obtain a regulatory approval, Tutogen shall be obligated
          to reimburse an amount determined by multiplying the Clinical Expenses
          for that Product by the Reimbursement Ratio. The "Reimbursement Ratio"
          is

                     10 yrs - (t\\exp\\ - t\\app\\) / 10 yrs,

          where t\\exp\\ is the effective date of termination of the Agreement
          and t\\app\\ is the date of regulatory approval for the Product. For
          example, if Sulzer obtains a regulatory approval for a Product at the
          beginning of the second Contract Year after incurring $100,000 of
          Clinical Expenses and the Agreement terminates at the beginning of the
          fifth Contract Year, the Reimbursement Ratio is

                     10 yrs - (3 yrs) / 10 yrs  =  0.7

          and Tutogen owes Sulzer $70,000. The reimbursement amount shall be
          paid in three equal annual installments due on the date of
          termination, one year after termination, and two years after
          termination, without interest.

                  deliver this Agreement and to perform its obligations

                  licenses granted in this Agreement.

           8.1.3  As of the date of this Agreement, and to the best of its
                  knowledge and belief, neither the manufacture, nor the use,
                  nor the sale of the Products in the Territory constitutes a
                  misuse or misappropriation of confidential information or
                  trade secrets or a breach of confidence, and

CONFIDENTIAL        First Amended International Distribution Agreement - Page 6


                  does not infringe or violate any valid patent, trademark, or
                  copyright or any other intellectual property rights of any
                  third party. Tutogen has disclosed to Sulzer all patents and
                  other intellectual property rights which, to Tutogen's
                  knowledge, may have a material effect on Sulzer's ability to
                  market the Products.

            8.1.4 Tutogen has not received notice that the manufacture, use, or
                  sale of the Products violates any patent rights or any other
                  intellectual property right or constitutes a misappropriation
                  or misuse of trade secrets or proprietary information.

            8.1.5 Tutogen shall promptly notify Sulzer of any claim of
                  infringement or misappropriation relating to the Products.

            8.1.6 To the best of Tutogen's knowledge and belief, Tutogen's
                  procurement of donor allograft tissue complies fully with all
                  laws of the country in which the donor tissue is collected,
                  including all national, regional, and local laws.

            8.1.7 To the best of Tutogen's knowledge and belief, Tutogen
                  possesses all governmental and other approvals required for
                  the collection and processing of donor allograft tissue, and
                  Tutogen shall use commercially reasonable efforts to maintain
                  all such approvals throughout the term of this Agreement.

            8.1.8 For a period of 12 months from the date of Tutogen's delivery
                  to Sulzer, each Product shall be free from defects in
                  material, manufacturing, and workmanship, including, but not
                  limited to, disease, excluding defects caused by the abuse,
                  misuse, neglect, or by improper testing, handling, storage, or
                  use by a party other than Tutogen.

            8.1.9 During the term of this Agreement, except as required by law
                  or by a pre-existing contractual obligation of Tutogen,
                  Tutogen will not, directly or through an Affiliate, assign,
                  sell, transfer, convey, or otherwise alienate in whole or in

          non-conforming Product or by repairing such Product. In no event shall
          the liability of Tutogen in connection with such warranty exceed the
          cost of replacing or repairing the defective Product. The foregoing
          shall constitute the exclusive remedy of Sulzer and the sole liability
          of Tutogen whether in contract or in tort or otherwise relating to a
          defect of a Product.

       customers, technology, and/or products 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 commercially reasonable
       precautions (and will cause its Affiliates to take commercially
       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 commercially reasonable efforts to provide the disclosing party
       with advance notice of such required disclosure to give the

CONFIDENTIAL        First Amended International Distribution Agreement - Page 12


       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 9.10
