4.     TERMINATION OF THE AGREEMENT.

              4.1.    TERMINATION WITHOUT CAUSE.  In the event that 
Corporation terminates this Agreement without Cause (as defined below), 
Officer shall be entitled to a severance payment equal to seven and one half

("Severance Payment"). Such Severance Payment shall be payable in monthly 
installments during the Severance Period, in accordance with the provisions 
set forth in Paragraph 3.1 above.  Officer shall not be entitled to receive a 
Severance Payment hereunder if he voluntarily terminates his employment or is 
terminated by reason of death or disability or for Cause.

              4.2.   TERMINATION FOR CAUSE.  Prior to the Termination Date, 
the Corporation shall have the right to terminate this Agreement for Cause 
immediately after written notice has been delivered to Officer, which notice 
shall specify the reason for and the effective date of such Termination.  For 
purposes of this Agreement, "Cause" shall mean the following:

       (i)    Officer's Material breach, repudiation or failure to comply with
              or perform any of the terms of this Agreement, any of Officer's
              duties, or any of Corporation's policies or procedures (including
              without limitation any such policies or procedures relating to
              conflicts of interests or standards of business conduct) or
              deliberate interference with the compliance by any other employee
              of Corporation with any of the foregoing;

       (ii)   The conviction of Officer for, or pleading by Officer of no
              contest (or similar plea) to, fraud, embezzlement,
              misappropriation of assets, malicious mischief, or any felony,
              other 


                                       4



              than a crime for which vicarious liability is imposed upon
              Officer solely by reason of Officer's position with Corporation
              and not by reason of Officer's conduct;

       (iii)  Any other act, omission, event or condition constituting cause for
              the discharge of any employee under applicable law.

              Before terminating the Agreement pursuant to this Paragraph 
4.2(i), Corporation first shall have given Officer written notice specifying 
the nature of the breach, repudiation or failure to comply and thirty (30) 
days thereafter in which to cure such breach, repudiation or failure to 
comply, and Officer shall have failed to cure.  For purposes of this 
Paragraph 4.2, "Material" shall mean a breach, repudiation or failure that 
the Board determines has resulted in material injury to Corporation.

              4.3.   OFFSET.  Although Officer shall not be required to 
mitigate damages under this Agreement by seeking other comparable employment 
or otherwise, the amount of any payment or benefit provided for in this 
Agreement shall be reduced by any compensation earned by or provided to 
Officer as the result of employment by an employer other than Corporation 
prior to the expiration of the Term of this Agreement. 

5.     NONCOMPETITION.

              During the Term of this Agreement, including the period, if 
any, with respect to which Officer shall be entitled to Severance Payments, 
Officer shall not engage in any activity that is or may be competitive with 
the business of Corporation, directly or indirectly, whether or not for 
compensation, including, but not limited to, providing services similar to 
those provided by the Company; offering or soliciting or accepting an offer, 
to provide such services or taking any action to form, or become employed by, 
a firm or business to provide such services.

that all confidential and proprietary information relating to the business of

Parties shall be submitted to ENDISPUTE for final and binding arbitration 
pursuant to ENDISPUTE's Arbitration Rules incorporated herein by reference, 
which arbitration shall take place in Los Angeles, California and shall be

competent jurisdiction.  Submission to arbitration shall not preclude the 
right of any party hereto involved in a dispute regarding this Agreement

              In addition to any other relief or award granted by the 
arbitrator to either Disputing Party, the arbitrator shall determine the 
extent to which each Disputing Party has prevailed as to the material issues 
raised in the arbitration, and, based upon such determination, shall 
apportion to each Disputing Party its ratable share of (i) the Disputing 
Parties' reasonable attorneys' fees and other costs reasonably incurred in 
the arbitration, (ii) the expense of the arbitrator, and (iii) all other 
expenses of the arbitration. The arbitrator shall make such determination and 
apportionment whether or not the dispute proceeds to a final award.           

              6.8.   SEVERABILITY.  Should a court or other body of competent 
jurisdiction determine that any provision of this Agreement is excessive in 
scope or otherwise invalid or unenforceable, such provision shall be adjusted 
rather than voided, if possible, and all other provisions of this Agreement 
shall be deemed valid and enforceable to the extent possible.

              6.9.   COUNTERPARTS.  This Agreement may be executed in one or 
more counterparts, all of which taken together shall constitute one and the 
same Agreement.

              6.10   INDEMNIFICATION.  In addition to any rights to 
indemnification to which Officer is entitled under the Corporation's Articles 
of Incorporation and By-Laws, Corporation shall indemnify Officer at all 
times during and after the Term of this Agreement to the maximum extent 
permitted under Section 2-418 of the General Corporation Law of the State of 
Maryland or any successor provision thereof and any other applicable state 
law, and shall pay Officer's expenses in defending any civil or criminal 
action, suit, or proceeding in advance of the final disposition of such 
action, suit, or proceeding, to the maximum extent permitted under such 
applicable state laws.
