extend for a period of six (6) months (the "Term"); provided, that either Darwin
or HSA may terminate all or any particular Service on thirty (30) days notice.

at least thirty (30) days prior to the expiration of the then existing Term.

         7. Default and Termination.

                  A. The following shall be deemed to be an "Event of Default"
hereunder:

                           [1] If any licenses or permits applicable to the
         Operations are canceled or revoked because either party has failed to
         perform its obligations hereunder and such


   4

         party is not, in good faith, diligently pursuing the reinstatement of
         such licenses or permits.

                           [2] If either party becomes insolvent or makes an
         assignment for the benefit of creditors or commits an act of bankruptcy
         or files a voluntary petition under the provisions of the United States
         Bankruptcy Code, including without limitation, a petition for
         reorganization or arrangement or consents to an involuntary petition or
         is adjudicated a bankrupt.

                           [3] If either party violates, or is in breach of, any
         material term or condition of this Agreement.

                  B. The party with respect to which an Event of Default is not
applicable may declare this Agreement terminated immediately.

                  C. Upon termination of this Agreement for any reason, any
outstanding accrued Service Fee and any advances by HSA pursuant to Section 5
hereof (collectively, "HSA Obligations") shall become immediately due and
payable and HSA is authorized to pay such amounts to itself from the accounts
maintained by it pursuant to Section 4.A hereof within five (5) days after
submission to Darwin of a calculation of such amounts.

         8. Cooperation at Termination. Upon the expiration or earlier
termination of this Agreement, the parties hereto shall cooperate fully with the
other in effecting an orderly transition to avoid any interruption in the
rendering of the Services and, in that connection, HSA shall surrender to Darwin
all contracts, books, records and reports maintained by HSA with respect to the
Operations.

         9. Indemnification. The party with respect to which an Event of Default
is applicable (the "Defaulting Party") shall indemnify and hold the other party
and its shareholders, directors, officers, employees and agents harmless from
any and all liabilities, losses, damages, claims, and costs arising from an
Event of Default, except for liabilities, losses, damages, claims, and costs
arising from the non-Defaulting Party's gross negligence, bad faith or willful
misconduct.

         10. Parties Bound. The provisions of this Agreement shall be binding
upon the parties hereto and their respective successors and assigns. Except as
specifically provided herein, no assignment of rights or delegation of duties
shall relieve either party, as the case may be, of its obligations hereunder.
Except as specifically provided herein, neither party may assign its rights or
delegate its duties under this Agreement without the prior written consent of
the other party; provided that a party may assign its rights and delegate its
duties to any successor entity in the event of a merger or a sale of
substantially all of the party's assets if the successor entity assumes all of
the party's obligations hereunder.

         11. Severability. In the event any provision hereof shall be modified
or held ineffective by any court in any respect, such adjudication shall not
invalidate or render ineffective the balance of the provisions of this
Agreement.


   5

         12. Entire Agreement; Modification; Waiver. This Agreement constitutes
the entire agreement between the parties with respect to the subject matter
hereof and completely supersedes all prior oral agreements between the parties.
All other agreements with respect to the subject matter hereof between the
parties, whether written or oral, are merged herein. No supplement,
modification, or amendment of this Agreement shall be binding unless executed in
writing by the parties hereto. No waiver of any of the provisions of this
Agreement will be deemed, or will constitute, a waiver of any other provision,
whether or not similar, nor will any waiver constitute a continuing waiver. No
waiver will be binding unless executed in writing by the party making the
waiver.

         13. Execution in Counterparts. This Agreement may be executed in
multiple counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same document.

         14. Further Assurances. The parties each hereby agree to execute and
deliver all of the agreements, documents, and instruments required to be
executed and delivered by them in this Agreement and to execute and deliver such
additional instruments and documents and to take such additional actions as may
reasonably be required from time to time in order to effectuate the transactions
contemplated by this Agreement.

         15. Tense; Captions. In construing this Agreement, whenever
appropriate, the singular tense shall also be deemed to mean the plural, and
vice-versa, and the captions contained in this Agreement shall be ignored.

         16. Governing Law. This Agreement shall be construed, interpreted, and
enforced in accordance with the substantive laws of the Commonwealth of
Kentucky.

         17. Parties in Interest. Nothing in this Agreement, whether express or
implied, is intended to confer any rights or remedies under or by reason of this
Agreement on any persons other than HSA and Darwin and their respective
successors and assigns, nor is anything in this Agreement intended to relieve or
discharge the obligation or liability of any third persons to any party to this
Agreement.
