RE:         Severance Agreement

        Dear Andy:

The purpose of this letter is to inform you that the Compensation Committee and
the Outside Directors Committee have approved the following modification to
Paragraph 3 of your long-form Severance Agreement and Paragraph 1 of the short
form:


         RETENTION POOL

         Duplex has created a Retention Pool to be used if any Change of Control
         is consummated. Upon the occurrence of any Change of Control, if
         Campbell is still employed by Duplex at the time of the Consummation of
         the Change of Control, then Campbell shall receive $100,000 from said
         Retention Pool, in one lump sum payable within ten (10) days after said
         transaction is consummated.

The following version of Paragraph 4 of the long form was also approved:

         All stock options issued under the 1984/1993 Incentive Stock Option
         program owned by Campbell at the time of the consummation of any Change
         of Control, no matter when granted and no matter what their vesting
         status, shall vest completely.

Your countersignature below will serve as proof of your acceptance of these 
modifications to your Severance agreement. Please return an executed copy to 
the corporate Secretary.

Sincerely,

/s/ Robert Reum

W. Robert Reum, Compensation Committee Chairman
