only to its officers, directors, employees and advisors who need to know the

the Confidential Information with the same degree of care to avoid unauthorized
disclosure as Company uses to protect its own Confidential Information of a
similar nature; but in no case less than reasonable care.  It is Company's
responsibility to ensure that any officers, directors, or employees to have
access to the Confidential Information will, prior to being provided with any or
all of the Confidential Information, agree to be bound by the terms of this
Agreement.  Company shall not use the Confidential Information in any respect to
compete with ProVantage at any time or provide such Information to a third party
to compete with ProVantage.

          c.  Immediately after Company's use of the Confidential Information
for the Permitted Use, or earlier upon written request by ProVantage, Company
shall return to ProVantage all of the Confidential Information, together with
summaries of the Confidential Information or shall destroy such summaries;
provided, however, that the Company may retain one copy of all the Confidential
Information in its legal files in order to monitor compliance with this
Agreement.

          d.  ProVantage will use its best efforts to ensure the accuracy and
completeness of the Confidential Information, but ProVantage does not make and
will not be deemed to have made any warranty as to the accuracy or completeness
of any of the Confidential Information.  ProVantage will not be liable for any
damages arising out of the use of the Confidential Information disclosed

          e.  Company will assume the liability for all damages, losses, costs,
or expenses which result from (i) the use of the Confidential Information by

Confidential Information by Company to third parties or entities; or (iii) the
use of the Confidential Information by any person or entity other than Company,
caused by the unauthorized disclosure or dissemination of same by any employees,
agents, or contractors of Company.

          f.  The foregoing obligations of Company will not apply to the extent
that the Confidential Information: (i) which, at the time of its disclosure, is
in the public domain

                                       2

 
or which, after disclosure, becomes part of the public domain by publication or
otherwise through no action or fault of Company; (ii) which Company can show was
in its possession at the time of disclosure and was not acquired, directly or
indirectly, from ProVantage; or (iii) which was received by Company from a third
party having a legal right to transmit the information.

          g.  Subject to Section 4 below, the foregoing obligations of Company
will not apply to the extent that Company is required by law to provide the
Confidential Information to a government agency or regulatory body.

whom it transmits any Confidential Information becomes legally compelled to
disclose any of the Confidential Information, Company will provide ProVantage
with prompt written notice before such Confidential Information is disclosed so
that ProVantage can seek a protective order or other appropriate remedy.  In the
absence of a protective order obtained by ProVantage or ProVantage's failure to
quash the legal process requiring disclosure or other measure effectively

production of Confidential Information and the production thereof shall not
constitute a breach of this Agreement.

business if any provision of this Agreement is breached and agrees that if there
should be any breach or threatened breach thereof, ProVantage shall be entitled
to an ex parte injunction prohibiting such conduct, and in the event final
judgement is entered in favor of ProVantage, the Company will reimburse
ProVantage for all court costs and legal fees, including reasonable attorney's
fees, incurred in enforcing this Agreement or obtaining relief hereunder other
