CONCENTRA REPORTS FIRST QUARTER RESULTS

ADDISON, Texas, May 8, 2007 – Concentra Operating Corporation (“Concentra Operating” or the “Company”) today announced its results for the first quarter ended March 31, 2007. Adjusted Earnings Before Interest Taxes Depreciation and Amortization (“Adjusted EBITDA”) grew by 15% in the quarter to $44,990,000 from $39,011,000, which was reported for the same period in 2006. Concentra Operating computes Adjusted EBITDA in the manner prescribed by its bond indentures, and a reconciliation of Adjusted EBITDA to net income is provided within this press release.

For the first quarter, the Company reported that revenue for the quarter increased 6% to $248,911,000 from $234,180,000 in the year-earlier period. Operating income was $25,148,000 in the first quarter, reflecting a 13% increase from $22,192,000 reported in the same period last year. Income from continuing operations increased 28% to $7,988,000 in the first quarter of 2007 from $6,251,000 in the year-earlier period. Net income, including loss from discontinued operations, declined 6% in the first quarter to $5,504,000 from $5,834,000 in the first quarter of 2006.

The Company also announced that its parent, Concentra Inc. (“Concentra”), plans to separate its two remaining principal operating segments – Health Services and Network Services – into two companies. As a part of the separation plan, Concentra Operating has formed a new wholly owned subsidiary, Viant Holdings, Inc. (“Viant”), which will acquire and independently operate Concentra’s Group Health Network Services business. Concentra will distribute to its shareholders the common shares of Viant to accomplish the separation. Daniel J. Thomas, the current President and Chief Executive Officer of Concentra, will lead Viant as its Chief Executive Officer and Thomas J. Bartlett will serve as its President.

In connection with the separation plan, Concentra Operating will be merged with and into Concentra, which will then continue as the parent company for its Health Services business. Concentra also will retain its Auto Injury Solutions business. In addition to its other existing senior officers, Concentra will be led by James M. Greenwood, who will become its Chief Executive Officer, and W. Keith Newton, who will be President and Chief Operating Officer. Daniel J. Thomas will serve as Non-executive Chairman of the Board of Concentra.

Commenting on the first quarter results, Daniel J. Thomas, Concentra’s President and Chief Executive Officer, said, “We are pleased with our strong first quarter results, particularly those provided by our health services business, which contributed significantly to the increases we experienced in both revenues and earnings. A higher-than-anticipated level of workers’ compensation-related care, together with other initiatives, helped produce a solid performance for this division. These results reflect a good start to the new year, especially in light of the recent sale of our workers’ compensation managed care services business units and the proposed corporate restructuring. I am very proud of the dedication and focus demonstrated by my Concentra colleagues. I look forward to maintaining the momentum generated during the first quarter and continuing the Company’s progress throughout 2007.”

In early April, Concentra Operating announced that it had completed the sale of its workers’ compensation managed care services business units to Maryland-based Coventry Health Care, Inc. for $387,500,000. The transaction resulted in net after-tax proceeds to Concentra Operating of approximately $273,263,000, of which $260,312,000 was used to prepay a portion of its senior-term indebtedness. Following this prepayment, Concentra Operating has $204,660,000 of senior term indebtedness outstanding.

Concentra Operating completed the first quarter of 2007 with $89,080,000 in unrestricted cash and investments and no outstanding borrowings under its revolving credit facility. The Company also currently anticipates it will not be required to remit income taxes incurred on its gain related to the Coventry transaction until September. Concentra’s days sales outstanding were 50 as compared to 52 in the same period last year.

Concentra Operating Corporation, a wholly owned subsidiary of Concentra Inc., is dedicated to improving the quality of life by making healthcare accessible and affordable. Serving the occupational, auto and group healthcare markets, Concentra provides employers, insurers and payors with a series of integrated services that include employment-related injury and occupational healthcare, urgent care services, in-network and out-of-network medical claims review and repricing, access to preferred provider organizations and other cost containment services.

Computations of Adjusted Earnings Before Interest Taxes Depreciation and Amortization ("Adjusted EBITDA") have been provided in this press release due to the use of this measure by the holders of the Company’s 9.5% senior subordinated notes and 9.125% senior subordinated notes, and other lenders, for purposes of determining the Company’s performance in light of its debt covenant requirements, which are stated in the Company’s debt agreements as measures that relate to Adjusted EBITDA. Adjusted EBITDA is disclosed because compliance with the liquidity covenants included in these agreements is considered material to the Company. The Company’s computations of this measure may differ from that provided by other companies due to differences in the inclusion or exclusion of items in its computations as compared to that of others. The Company’s measure of Adjusted EBITDA has been prepared in accordance with the requirements of the indenture that relates to its 9.5% senior subordinated notes and 9.125% senior subordinated notes. Adjusted EBITDA is a measure that is not prescribed for under Generally Accepted Accounting Principles ("GAAP"). Adjusted EBITDA specifically excludes changes in working capital, capital expenditures and other items that are set forth on a cash flow statement presentation of a company’s operating, investing and financing activities, and it also excludes the effects of interest expense, depreciation expense, amortization expense, taxes and other items that are included when determining a company’s net income. As such, the Company would encourage a reader not to use this measure as a substitute for the determination of net income, operating cash flow, or other similar GAAP-related measures, and to use it primarily for the debt covenant compliance purposes above.
