INC., a Utah corporation ("Orca").

     WHEREAS, Televar, Orca Acquisition and Tel-Sub Corp., a wholly-owned 
subsidiary of Acquisition which has been merged with and into Acquisition

Acquisition, through Acquisition Sub, acquired substantially all of the assets, 
and assumed certain designated liabilities, of Televar; and

     WHEREAS, in connection with the Purchase Agreement, Acquisition Sub and 
Boss executed an Assumption of Liabilities (the "Assumption Agreement"), 
pursuant to which Acquisition Sub assumed those liabilities of Televar 
designated as "Assumed Liabilities" therein, and Boss guaranteed payment of all 
such liabilities; and

     WHEREAS, certain liabilities of Televar were not included in the designated
liabilities assumed by Acquisition Sub pursuant to the Purchase Agreement and

     WHEREAS, Acquisition has paid, on Televar's behalf, certain amounts owed by
Televar to Corkrum; and

     WHEREAS, the parties to the ADS Dispute and Acquisition propose to enter 
into a settlement agreement in that dispute, and in aid of effecting this 
settlement, Acquisition has agreed to pay, on Televar's behalf, certain amounts 
payable to ADS in connection therewith; and

     WHEREAS, in consideration of Acquisition paying certain amounts owed to 
Corkrum and as a condition to Acquisition paying certain amounts payable in 
connection

provided that Acquisition's only participation in the ADS Settlement Agreement 
is to consent to termination of that certain Exclusive Sales Agency Agreement 
between Televar and ADS which was assigned to Acquisition pursuant to the

Amount and to enter into the ADS Settlement Agreement is conditioned upon the

indebtedness issued to Televar, Orca or any of their affiliates by Corkrum or 
any of its affiliates, marked "canceled" and (iii) release of any security 
interest granted by Corkrum or any of its affiliates in connection with any such
