            perform his duties hereunder (other than as a result of total or
            partial disability or incapacity due to physical or mental illness)
            after a written demand for substantial performance is delivered to
            the Executive by the Company or GmbH, which demand identifies the
            manner in which the Company or GmbH, believes that the Executive has
            not substantially performed his duties.

      8.    CONFIDENTIAL INFORMATION. The Executive acknowledges that all
Confidential Information is the property of the MedVest Entities. Therefore, the
Executive agrees that he shall not disclose to any unauthorized Person or use
for his own purposes any Confidential Information without the prior written
consent of the Board, unless and to the extent that the Confidential Information
becomes generally known to and available for use by the public other than as a
result of the Executive's acts or omissions or as requested or required by law
or court order (provided that the Executive shall notify the Company promptly of
such request or requirement so that the Company may seek an appropriate
protective order). The Executive shall deliver to the Company at the termination

patentable) which relate to the MedVest Entities' actual business, research and
development or existing or future products or services and which are conceived,
developed or made by the Executive while employed by the Company or GmbH ("WORK
PRODUCT") belong to the MedVest Entities. The Executive shall promptly disclose
such Work Product to the Board and, at the Company's expense, perform all
actions reasonably requested by the Board (whether during or after the Term) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments).

      10.   SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
and be binding upon the parties hereto and their respective legal
representatives, heirs, or successors and permitted assigns; PROVIDED, HOWEVER,
that the Executive may not sell, assign, pledge, hypothecate, or otherwise
transfer this Agreement or any part hereof without the prior written consent of
the Company. The Company will require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or the assets of the Company to assume expressly and to agree
to perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.

      11.   INDEMNIFICATION. To the fullest extent permitted by law, the Company
agrees to, and shall provide in its code of regulations all necessary provisions
so as to cause the Company to, indemnify and hold the Executive harmless against
and from any and all loss, cost, liability or expense that may be imposed upon
or reasonably incurred by him in connection with or resulting from any claim,
action, suit or proceeding to which he may be a party or in which he may be
involved by reason of any action taken or failure to act in his capacity as an
officer of the Company during this Agreement. The Company further agrees, at all
times while the Executive remains employed by the Company, to provide reasonable
and adequate coverage for the benefit of the Executive under the Company's D&O
policy provided coverage under such D&O

                                      - 6 -

insurance is commercially available and can be obtained at reasonable cost. The
foregoing right of indemnification shall not be exclusive of any other right to
which the Executive may be entitled to as a matter of law or otherwise, or any
power that the Company may have to indemnify him or hold him harmless, but shall
be subject to any applicable restrictions imposed by the code of regulations of
the Company from time to time and any applicable law and shall not apply in
respect of any loss, cost, liability or expense that is found, in a final
judgment by a court of competent jurisdiction from which no appeal can be or has
been taken, to have resulted principally from the Executive's bad faith, gross
negligence or willful misconduct.

      12.   GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED UNDER THE LAWS OF THE STATE OF OHIO WITHOUT REGARD TO ITS
CONFLICT OF LAWS PROVISIONS.

      13.   INTERPRETATION. This Agreement is the result of negotiations between
the parties and accordingly, shall not be construed for or against either party
regardless of which party drafted this Agreement or any portion thereof.

      14.   NOTICES. All notices required or permitted to be given pursuant to

receipt requested, postage prepaid or by recognized overnight carrier addressed:
(i) in the case of the Company or GmbH, to the Company at its principal office
and (ii) in the case of the Executive, at the last known residence as shown on
the Company's records.

      15.   WAIVER. A delay or failure by either party to require strict
performance by the other party of any undertakings or agreements contained in
this Agreement will not waive, affect or diminish any right of such party
thereafter to demand strict compliance and performance therewith. Any waiver by
either party of any default by the other party under this Agreement will not
waive or affect any other such default, whether such default is prior or
subsequent thereto and whether of the same or a different type.

      16.   SEVERABILITY. In the event that any provision of this Agreement
shall be held by a court of competent jurisdiction to be invalid, illegal or
unenforceable, it shall not affect any other provision hereof, and this
Agreement shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein, unless to do so would cause this
Agreement to fail of its essential purpose.

      17.   ENTIRE AGREEMENT. This Agreement constitutes the entire
understanding and agreement between the Company and the Executive with respect
to the terms and conditions of the Executive's employment by GmbH during the
Term and supersedes all previous agreements and arrangements (if any), oral or
written, relating to the employment of the Executive by the Company, GmbH or any
other MedVest Entity (which shall be deemed to have been terminated by mutual
consent). There are no other agreements, conditions, or representations, oral or
written, express or implied with regard thereto.

hereunder will survive any termination of this Agreement to the extent necessary
to the intended preservation of such rights and obligations.

      20.   COUNTERPARTS. This Agreement may be executed simultaneously in
counterparts, each of which shall be deemed an original but which taken together
shall constitute a single agreement between the parties.

      21.   HEADINGS. The Section headings herein are inserted for convenience
of reference only, do not constitute a part of this Agreement, and shall not be
deemed to limit or affect the meaning or interpretation of any of the provisions
herein.

      22.   SUCCESSOR-IN-INTEREST. The Executive may designate a Successor (or
Successors) in Interest to receive any and all amounts due the Executive in
accordance with this Agreement should the Executive be deceased at any time of
payment. Such designation of Successor(s) in Interest shall be made in writing
and signed by the Executive. Any such designation may be made to any legal
person, persons, trust or the Executive's estate as he shall determine in his
sole discretion. In the event any designation shall be incomplete, or in the
event the Executive shall fail to designate a Successor-in-Interest, his estate
shall be deemed to be his Successor-in-Interest to receive such portion or all
of the payments due hereunder. The Executive may amend, change or revoke any
such designation at any time and from time to time, in the same manner.
