Director, Environmental Services

                                                                 October 9, 1996

Re: Roatan Equipment

Dear Mr. Husman,

Following your discussion with Mark Hale and myself, we commit to the following:

o  Effective October 15, 1996, Roatan will bear the cost of the box/bag disposal
   shortfall daily, up to 1,470 lbs. at a cost of $.023/lb. This calculation
   is based on Presbyterian Hospital of Dallas (PHD) running the machines
   12 hours/day, 7 days/week. If PHD chooses not to run the machines on that
   basis, the shortfall will be reduced accordingly. PHD will be reimbursed by
   Roatan on a monthly basis until such time as the machines are operating
   consistently to represented specifications or 48 months, whichever comes
   first.

o  Roatan will reimburse PHD for labor costs at a rate of $8.30/hour, up to
   12 hours/day, up to 7 days/week for the time PHD chooses to operate the
   equipment, for the dedicated operation of the equipment during the same
   period of time described above. Roatan will train the operator to do
   preventive, simple maintenance.

o  Roatan will maintain 150 processing cans at PHD for 48 months. Defective
   cans will be replaced at no charge by Roatan during this period.

o  Roatan will maintain a stock of parts at PHD. These parts will include
   windows, "o" rings, filters, gaskets, sealants, and other commonly needed
   maintenance parts. PHD will provide secured storage for said materials at
   no cost to Roatan.

o  Roatan will provide a fourth sterilizer to PHD at no cost, at such time
   sterilizer efficiency is restored, and PHD has definable space. PHD will
   provide space and utility access; Roatan will install the machine and
   complete final hookups.

o  The terms and agreements between PHD and Roatan are not available as public
   information.

Thank you for your continued support. May I assure you that we are committed -
as indicated in the past - to bring our joint effort to a successful conclusion.

Sincerely yours,

/s/ W. H. LIESNER

W. H. Liesner
President
