URS CORPORATION ANNOUNCES
TENDER OFFER FOR OUTSTANDING 11¹/2% NOTES;
PROCEEDS FROM OFFERING OF COMMON STOCK
TO BE USED FOR NOTE REPURCHASE

Company Also Announces Planned Refinancing of Senior Credit Facility
______________________________________________________________

     SAN FRANCISCO, CA – June 1, 2005 – URS Corporation (NYSE:URS) announced today that it is commencing a tender offer (the “Note Repurchase”) to purchase, for cash, any and all of its outstanding $130 million aggregate principal amount of 11¹/2% Senior Notes Due 2009 (the “11¹/2% Notes”). The purchase price for each $1,000 principal amount of 11¹/2% Notes validly tendered and accepted for purchase will be determined by the yield to the earliest redemption date of the 11¹/2% Notes of a fixed spread of 50 basis points (0.50%) over the yield to maturity of the 2.5% U.S. Treasury Note due September 30, 2006, as calculated on June 15, 2005. The total estimated consideration to acquire all outstanding 11¹/2% Notes, based upon such yield as of May 31, 2005, and an assumed date of purchase of June 30, 2005, is approximately $148.4 million, or $1,141.90 per $1,000 principal amount of 11¹/2% Notes, including a consent payment of $30.00 per $1,000 principal amount of 11¹/2% Notes payable only to holders who tender their 11¹/2% Notes and deliver their consents to the proposed amendments to the indenture for the 11¹/2% Notes on or prior to June 14, 2005. The proposed amendments would eliminate from the indenture substantially all of the restrictive covenants and certain events of default and related provisions. Holders who tender their 11¹/2% Notes after June 14, 2005 and prior to the expiration date for the Note

1

Repurchase on June 29, 2005 will be entitled to receive the total consideration less the consent payment. Holders whose 11¹/2% Notes are repurchased also will be paid accrued and unpaid interest on the 11¹/2% Notes.

     The Company intends to fund the Note Repurchase with proceeds from a proposed public offering of 3.69 million shares of common stock, together with available cash and borrowings, if necessary. Assuming all 11¹/2% Notes are tendered and accepted by the Company at the offer price, the Company will recognize a charge, net of income taxes, of approximately $16.2 million in the second quarter of fiscal 2005.

     The terms and conditions of the Note Repurchase will be set forth in the Company’s Offer to Purchase and Consent Solicitation Statement (the “Offer to Purchase”), which will be distributed to the holders of the 11¹/2% Notes on June 1, 2005. Subject to applicable law, the Company may, in its sole discretion, waive any condition applicable to the Note Repurchase or extend or terminate or otherwise amend the Note Repurchase. The consummation of the Note Repurchase is subject to certain conditions, including the successful completion of the Company’s proposed common stock offering, the tender of at least two-thirds of the outstanding principal amount of 11¹/2% Notes and the receipt of waivers under the Company’s existing senior credit facility or the refinancing of that facility to permit it to consummate the Note Repurchase, all as fully described in the Offer to Purchase.

     Credit Suisse First Boston LLC (“Credit Suisse”) will act as dealer manager and solicitation agent for the Note Repurchase and the consent solicitation, and Georgeson Shareholder Communications Inc. (“Georgeson”) will be the information agent. Information concerning the calculation of the purchase price of the 11¹/2% Notes will be available from Credit Suisse at the following numbers: (800) 820-1653 (toll free) or (212) 440-8474 (call collect). Requests for assistance or additional sets of the offering materials may be directed to Georgeson at the following numbers: (800) 223-2064 (toll free) or (212) 440-9915 (call collect).

     This announcement is not an offer to purchase, a solicitation of an offer to purchase or a solicitation of an offer to sell securities, with respect to any 11¹/2% Note. The tender offer may only be made pursuant to the terms of the Offer to Purchase and the accompanying Consent and Letter of Transmittal (the “Letter of Transmittal”). Each
