     None of the Reporting Persons have engaged in any transactions in PEC
Common Stock in the past sixty days. The filing of this Amendment No. 5 to
Schedule 13D is necessitated solely by the fact that the Reporting Persons's
percentage ownership of PEC's Common Stock has increased by virtue of the
repurchase by PEC of shares of the Common Stock in open market and private
transactions from time to time during the period ended December 31, 2003, which
resulting in a decrease in the number of outstanding shares of Common Stock to
3,630,102. As a result, the net beneficial ownership by Amrace Inc. of Common
Stock has increased to 13.6% of the outstanding shares at that date.


     6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE ISSUER.
