utilization  with a line of passive  monitors  developed  by EDC,  wherein  both
parties had certain rights, duties and obligations, and

WHEREAS, EV was a guarantor of EDC's obligation under the Agreement, and

WHEREAS, CCC sent notice to EDC on July 17, 1997 alleging that EDC was in breach
of the Agreement  because it owed accrued  royalties and accounts  receivable to
CCC,  and on  August  25,  1997,  CCC  notified  EDC of its  termination  of the
Agreement, and

WHEREAS,  EVRM and CCC wish to resolve  their  remaining  obligations  under the
Agreement in an amicable and mutually acceptable manner;

NOW, THEREFORE, in consideration of the Recitals,  which are incorporated herein

     Liabilities   result   or  arise,   directly   or   indirectly,   from  any
     relationship(s)  of EVRM (or either of them) with CCC  through  the date of
     this Release ("Relationships"), or from any act of EVRM (or either of them)
     on or before the date of this Release ("EVRM Acts"). Relationships include,
     but are not limited to,  obligations  stated in the  Agreement  (and/or any
