service with the Company and any settlement of the financial rights and
obligations arising from its service with the Company. Upon the earlier of the

         8. Termination. Each party shall have the right to terminate this
Agreement at any time and for any reason upon one (1) month prior Notice (as

         9.       Indemnification & Insurance Coverage

                  9.1 Throughout the term of the Agreement and for the period of
six (6) years thereafter, the company will maintain an Officers and Directors
Insurance policy for the Director, and other insurance coverage on substantially
the same terms and levels that it provides to the Company's senior Executive
Officers, at the company's sole expense. This insurance shall cover any and all
actions committed and/or omitted by the Director, in his capacity as Director,
commencing on the appointment of Director as a Director of the company .

                  9.2 Director is not and shall not be liable to the Company for
any losses, claims, damages or liabilities arising from his appointment as
Director and/or any action and/or failure to act in his capacity as Director or
from any act or omission performed or omitted by Director, except for any
losses, claims, damages or liabilities primarily attributable to such Director's
fraud, gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

                  9.3 The Company, to the fullest extent permitted by applicable
law, indemnifies and holds Director harmless (and his respective successors and
assigns) against any losses, claims, damages, liabilities, costs or expenses
(including legal fees, judgements and amounts paid in settlement) to which the
Director may become subject (i) by reason of having been a Director to the
Company or (ii) in connection with any matter arising out of or in connection
with this Agreement, unless a court of competent jurisdiction, in a judgement
that has become final and that is no longer subject to appeal or review,
determines that any such loss, claim, damage, liability, cost or expense is
primarily attributable to Director's fraud, gross

                                       3
<PAGE>

negligence or willful misconduct. If Director becomes involved in any capacity
in any action, proceeding or investigation by reason of being or having been a
Director or in connection with any matter arising out of or in connection with
this Agreement, the Company will periodically reimburse the Director for its
legal or other expenses( including the cost of any investigation and
preparation) incurred in connection therewith; provided that Director promptly
repays to the Company the amount of any such reimbursed expenses paid to it to
the extent that it is ultimately determined that Director is not entitled to be
indemnified by the Company in connection with such action, proceeding or
investigation as provided in the exception contained in the immediately
preceding sentence. If for any reason (other than the fraud, gross negligence or
willful misconduct of Director) the foregoing indemnification is unavailable to
Director, or is insufficient to hold it harmless, then the Company must, to the
fullest extent permitted by law, contribute to the amount paid or payable by the
Director as a result of such loss, claim, damage or liability in such proportion
as is appropriate to reflect the relative benefits received by the Company, on
the one hand, and the Director on the other hand or, if such allocation is not
permitted by applicable law, to reflect not only the relative benefits referred
to above but also any other relevant equitable considerations.

         10. Miscellaneous. This Agreement sets forth the parties' final and
entire agreement, and supersedes any and all prior understandings, with respect
to its subject matter. The headings in this Agreement are for convenience of
reference only and shall not affect the interpretation of this Agreement. No
failure or delay by either party in exercising any right, option, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise thereof preclude any other or further exercise thereof, or the
exercise of any other right, option, power or privilege. This Agreement can be
changed, waived or terminated only by a writing signed by both the Director and
the Company.

         11. Assignment. This Agreement may not be assigned in whole or in part
by the Director . This Agreement shall be assignable by the Company to any of
its subsidiaries or affiliates and may be reassigned by such subsidiary or
affiliate to the Company; provided that each such assignee shall agree in
writing to assume all obligations of the Company hereunder, and provided further
that no assignment shall be made without the prior consent of both parties. This
Agreement shall inure to the benefit and be binding upon the personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees, legatees and permitted assignees of the parties hereto.
