         The Company agrees to indemnify and hold harmless Lycke from any and

for all purposes of this Article III, but not be limited to, reasonable counsel
fees and any and all expenses whatsoever incurred in investigating, preparing,
or defending against any litigation, commenced or threatened, or any claim
whatsoever, and any and all amounts paid in settlement of any claim or
litigation) as and when incurred arising out of, based upon, or in connection
with (i) the Employment Agreement, and (ii) this Agreement, in each case to the
maximum extent permitted by the Delaware General Corporation Law. The foregoing
agreement to indemnify shall be in addition to any liability the Company may
otherwise have, including liabilities arising under this Agreement.

                                IV. MISCELLANEOUS

         SECTION 4.01 FURTHER ACTIONS. At any time and from time to time, each
party agrees, at its or his expense, to take such actions and to execute and
deliver such documents as may be reasonably necessary to effectuate the purposes
of this Agreement.

         SECTION 4.02 AVAILABILITY OF EQUITABLE REMEDIES. Since a breach of the
provisions of this Agreement could not adequately be compensated by money

                                       2


<PAGE>

damages, any party shall be entitled, in addition to any other right or remedy
available to it, to an injunction restraining such breach or a threatened breach
and to specific performance of any such provision of this Agreement, and in
either case no bond or other security shall be required in connection therewith,
and the parties hereby consent to the issuance of such an injunction and to the
ordering of specific performance.

         SECTION 4.03 SURVIVAL. The covenants, agreements, representations, and
warranties contained in or made pursuant to this Agreement shall survive any
delivery of the consideration described herein, irrespective of any
investigation made by or on behalf of any party.

         SECTION 4.04 MODIFICATION. This Agreement sets forth the entire
understanding of the parties with respect to the subject matter hereof,
supersedes all existing agreements between them concerning such subject matter,
and may be modified only by a written instrument duly executed by each party
with the approval of the Board of Directors or by an officer of each corporate
party.

         SECTION 4.05 NOTICES. Any notice or other communication required or
permitted to be given hereunder shall be in writing and shall be mailed by
certified mail, return receipt requested (or by the most nearly comparable
method if mailed from or to a location outside of the United States) or by

of receipt thereof. Any notice given by other means permitted by this Section
9.06 shall be deemed given at the time of receipt thereof. A copy of any notice

New York 10022, Attention: Robert Steven Brown, Esq.

         SECTION 4.06 WAIVER. Any waiver by any party of a breach of any term of
this Agreement shall not operate as or be construed to be a waiver of any other
breach of that term or of any breach of any other term of this Agreement. The
failure of a party to insist upon strict adherence to any term of this Agreement
on one or more occasions will not be considered a waiver or deprive that party
of the right thereafter to insist upon strict adherence to that term or any
other term of this Agreement. Any waiver must be in writing and, in the case of
a corporate party, be authorized by a resolution of the Board of Directors or by
an officer of the waiving party.

         SECTION 4.07 BINDING EFFECT. The provisions of this Agreement shall be
binding upon and inure to the benefit of the Company, Lycke, and their
respective successors and assigns (if not a natural person) and his assigns,
heirs, and personal representatives (if a natural person).

         SECTION 4.08 NO THIRD PARTY BENEFICIARIES. This Agreement does not
create, and shall not be construed as creating, any rights enforceable by any
person not a party to this Agreement (except as provided in Section 4.07).

         SECTION 4.09 SEPARABILITY. If any provision of this Agreement is
invalid, illegal, or unenforceable, the balance of this Agreement shall remain
in effect, and if any provision is inapplicable to any person or circumstance,
it shall nevertheless remain applicable to all other persons and circumstances.

         SECTION 4.10 HEADINGS. The headings in this Agreement are solely for
convenience of reference and shall be given no effect in the construction or
interpretation of this Agreement.

         SECTION 4.11 COUNTERPARTS; GOVERNING LAW. This Agreement may be
executed in any number of counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument. It shall be governed by and construed in accordance with the laws of
New York, without giving effect to conflict of laws. Any action, suit, or

                                       4


<PAGE>

proceeding arising out of, based on, or in connection with this Agreement or the
transactions contemplated hereby may be brought in the United States District
Court for the Southern District of New York and each party covenants and agrees
not to assert, by way of motion, as a defense, or otherwise, in any such action,
suit, or proceeding, any claim that it or he is not subject personally to the
jurisdiction of such court, that its or his property is exempt or immune from
attachment or execution, that the action, suit, or proceeding is brought in an
inconvenient forum, that the venue of the action, suit, or proceeding is
improper, or that this Agreement or the subject matter hereof may not be
enforced in or by such court.
