                         that amicable resolution through continued negotiation

<PAGE>
 
     16.1. Differences between the Client and ICT on which an Agreement cannot
           be reached will be decided by arbitration. The arbitrators will
           determine the interpretation of the Agreement in accordance with
           usual business and insurance practices rather than strict
           technicalities.

     16.2. Any arbitration shall be conducted in accordance with the rules of
           the American Arbitration Association.

     16.3. Either party may serve upon the other party by certified mail a
           written demand that the claim, dispute or controversy, be arbitrated,
           specifying in reasonable detail the nature of the dispute or claim to
           be submitted to arbitration. The demand, which shall be effective
           upon receipt, shall be made within a reasonable time after the claim,
           dispute or controversy has arisen. In no event shall the demand for
           arbitration be made more than one year after the claim or cause of
           action arises.

     16.4. Within thirty (30) days after service of a demand for arbitration,
           the parties shall agree upon three (3) arbitrators. These arbitrators
           must have no past or present relationship with the parties to this
           Agreement. One of the arbitrators is to be appointed by Client and
           one by ICT and these two arbitrators will select a third. If the two
           are unable to agree on a third within thirty (30) days, the choice
           will be left to the American Arbitration Society (Philadelphia
           Office). The rules governing the procedure of any arbitration
           hereunder shall be in accordance with the rules provided by the
           American Arbitration Society.

     16.5. All arbitration hearings shall be held in Philadelphia, Pennsylvania.
           Judgment upon the award rendered by the arbitration may be entered in
           any court having jurisdiction thereof.

     16.6. The arbitrators are not bound by rules of law. Their decision will be
           by majority vote and no appeal will be taken from it.

     16.7. The cost of the arbitration will be borne evenly by each party unless
           the arbitrators decide otherwise.


SECTION 17.  RELATIONSHIP

           relationship of employer and employee between ICT and Client or
           between Client and any of ICT's employees or agents. It is the
           express intent of the parties hereto that ICT is not an employee of
           Client for any purpose, but is an independent contractor for all
           purposes and in all situations. ICT and ICT's employees shall not
           represent that they are employees of Client, nor shall they in any
           manner hold themselves out to be employees of Client.

     17.2. Neither party shall have the right to enter into any Agreement or
           commitment in the name of or on the behalf of the other, or to bind
           the other in any respect whatsoever, unless specifically authorized
           in writing by the other.

           Compensation-Statutory Limits as required by Labor Code of the State
           of Pennsylvania; and Crime Coverage Insuring Employee Theft.


SECTION 19.  GOVERNING LAW

     19.1. This Agreement shall be construed in all respects under the laws of
           the Commonwealth of Pennsylvania. If any part of this Agreement shall
           be held to be void or unenforceable, such part will be treated as
           severable, leaving valid the remainder of this Agreement
           notwithstanding the part or parts found to be void or unenforceable.

           any way be affected or be impaired thereby.

     20.4. Limitations. No action, other than an action for non-payment,

           has arisen.

     20.5. Waivers. A waiver of a breach or default under this Agreement shall
           not be a waiver of any other or subsequent breach or default. The
           failure or delay by either party in enforcing compliance with any
           term or condition of this Agreement shall not constitute a waiver of
           such term or condition unless such term or condition is expressly
           waived in writing.

     20.6. Force Majeure.  Either party's failure to perform any of its
           obligations hereunder, except for the obligation to pay monies when
           due hereunder, shall be excused and shall not give rise to any claims
           for damages to the extent it is caused by an event or occurrence
