CONCENTRA ANNOUNCES COMPLETION OF $150 MILLION SENIOR SUBORDINATED NOTES SALE AND $435 MILLION SENIOR CREDIT FACILITY

ADDISON, Texas, August 13, 2003 – Concentra Operating Corporation (“Concentra” or “the Company”) today announced that it has sold in a private placement $150 million aggregate principal amount of its 9.5% Senior Subordinated Notes due 2010, in accordance with Securities and Exchange Commission Rule 144A. In addition, the Company announced the closing of a new $435 million senior credit facility, which replaced its previously outstanding senior credit facility.

The new 9.5% Senior Subordinated Notes are general unsecured obligations of the Company, are subordinated to all existing and future senior debt of the Company, and rank pari passu with the Company’s existing 13% senior subordinated notes due 2009. The new $435 million senior credit facility is comprised of $335 million in term debt with a six-year maturity and a $100 million five-year revolving credit facility. The Company had no borrowings under the revolving credit facility as of the closing date.

The Company has used the net proceeds of the private offering and borrowings under the new senior credit facility, together with cash on hand, to retire its previously outstanding senior credit facility, to terminate its interest rate hedge agreements, to transfer cash proceeds to Concentra Inc., its parent corporation, to enable it to redeem approximately $139,000,000 of the principal and accreted interest of its 14% Senior Discount Debentures due 2011, and to pay related fees and expenses.

This announcement is neither an offer to sell nor a solicitation of an offer to buy the securities described herein. The securities sold have not been registered under the Securities Act of 1933 or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
