* CONFIDENTIAL TREATMENT REQUESTED

               Director of Technical Services shall meet and resolve the issue;

maintain (or cause to be in effect), liability insurance covering negligence of
itself and its' subcontractors, with limits of not less than [*] per incident

admitted to do business in the State of New York or from a duly established and
funded self-or pooled- insurance program.  Any insurance carrier providing such
coverage shall give CUSTOMER at least thirty (30) days advance notice of
cancellation or material change in any such coverage.  DAOU shall not commence
performance under this Principle Agreement until it has obtained, at its own
expense, all insurance required under this Principle Agreement.  DAOU warrants
that all required insurance shall be maintained until its work under this
Principle Agreement is complete, provided that, if DAOU fulfills any of the
insurance requirements set forth herein by the use of claims-made policies. 
DAOU warrants that these policies shall be kept in effect for at least three (3)
years following completion of its work under this Principle Agreement and if its
claims-made policies are canceled during the Term of the Principle Agreement,
DAOU will purchase tail coverage for the remainder thereof.  DAOU will furnish
CUSTOMER with a certificate of insurance within ten (10) business days of the
execution of the Principle Agreement.

26.  FORCE MAJEURE:

Neither DAOU nor CUSTOMER shall be responsible for any delay or failure of
performance resulting from causes beyond its control without its fault or
negligence.  If a force majeure event occurs the party being delayed or failing
to perform shall promptly notify the other party of the nature of such cause and
its reasonably anticipated duration and if either party declares a force majeure
event, the parties shall meet as soon thereafter as possible to determine the
nature and extent of the event, the expected impact of the event on CUSTOMER's
processing capabilities, and a recommended course of action intended to enable
CUSTOMER to process its data in the operation of the Facility.

employee, agent, or representative of the other party.
