Dear Customer:

In order to continue the best possible service, we wish to assist you in understanding recent eventsrelating to the Pentex' blood proteins.

Recently, the biochemical segment of Miles Scientific Division was sold to ICN Pharmaceuticals. At thesame time, an agreement was entered for ICN to distribute the small pack sizes of the Pentex bloodproteins used in research. The purpose of this letter is to clarify purchasing since some confusionappears to have resulted from these changes. Bulk proteins intended for process/product engineering,establishment of performance specifications, or trial manufacturing should be ordered directly fromMiles in Kankakee. This may be done by either telephone or telex:

TELEPHONE: (815) 937-8458TELEX: 215094

These same blood proteins are sold in large, or bulk, quantities to manufacturers and industrial users.This segment of the market will continue to be handled directly by Miles. The only change which hasoccurred with respect to these bulk products is that distribution and invoicing are now from Kankakeeinstead of Naperville, IL. We expect this change will improve order turnaround and technical servicesupport since Pentex blood proteins will continue to be manufactured at Kankakee.

It continues to be Miles' policy to support top quality products with the same quality service. Thus, welook forward to continuing as your supplier of these Pentex products.

Yours very truly,

E. DickinsonPentex Products
