   RE:  Cadence Company

   Dear Fred:

   Per our conversation of last Friday, Cadence Company has authorized me to
   advise Oshkosh Truck Corporation that they will consent to a 5-year
   extension of the lease of the PDC property on Waukau Ave. at the contract
   rental price of $128,400.00 per year, payable in monthly installments
   according to the terms of the lease.  At the same time, they have declined
   the offer of Oshkosh Truck Corporation to purchase the property on your
   offer price.

                                 Very truly yours,

                            Dempsey, Magnusen, Williamson & Lampe



                                 Timothy M. Dempsey
