The Senior Notes were remarketed at a price of 101.311% of the $50 principal amount of the Senior Notes. As a result of the remarketing, the annual interest rate on the Senior Notes will remain at 4.90%, and the Senior Notes will no longer form a part of the MEDS Equity Units. Pursuant to the terms of the MEDS Equity Units and the Senior Notes, the holders of $65.12 million aggregate principal amount of the Senior Notes elected not to participate in the remarketing and will remain outstanding at the 4.90% reset rate. The remarketing is scheduled to close on March 24, 2005. J.P. Morgan Securities Inc. is the remarketing agent for the transaction. Proceeds of the remarketed Senior Notes will be used to purchase a portfolio of U.S. Treasury securities that will be pledged to secure the MEDS Equity Units' obligations under the stock purchase contract component of the MEDS Equity Units. The proceeds in excess of the purchase price of the portfolio of U.S. Treasury securities, net of the remarketing agent's fee, were equal to $847,754 (or approximately $0.1073 per Corporate MEDS Equity Unit) and will be distributed to holders who were record holders of the MEDS Equity Units on March 18, 2005.
