URS to Acquire Flint Energy Services for C$1.25 Billion

Will Significantly Expand URS Presence in Fast-Growing Segments of North American Oil and Gas Industry, Particularly in Unconventional Oil and Gas Extraction

Acquisition Expected to be Accretive to URS 2012 GAAP Earnings, Adds Substantial Oil and Gas Backlog

URS Also Provides Fiscal 2012 Financial Guidance

URS Corporation (NYSE: URS - News) and Flint Energy Services Ltd. (TSX: FES.TO - News) today announced a definitive agreement under which URS will acquire Flint for C$25.00 per share in cash, or C$1.25 billion (US$1.25 billion). URS also will assume approximately C$225 million (US$225 million) in Flint debt.

The transaction, which has been approved unanimously by the URS and Flint Boards of Directors, will significantly expand URS’ opportunities to serve clients in the oil and gas industry. Flint, a leading provider of construction services for the oil and gas industry, currently supports many of the largest companies operating in the oil, oil sands and gas producing regions of Western Canada and in the Southwest, Appalachian and Rocky Mountain regions of the United States.

The acquisition will be implemented through a court-approved Plan of Arrangement under Canadian law and is subject to the approval of Flint security holders, relevant regulatory approvals and other customary closing conditions. The transaction is expected to close in the second quarter of 2012, to be accretive to URS’ 2012 GAAP earnings, and to increase URS’ revenues from the oil and gas sector to approximately 22% of total revenues.

Flint has approximately 10,000 employees and a network of approximately 80 locations in North America. The company’s diversified activities span the full cycle of oil and gas exploration and production, including constructing well pads, moving rigs, manufacturing processing equipment, installing small and mid-diameter pipelines, transporting fluids, performing a wide range of mid-cycle production services, and constructing and maintaining large oil sands facilities. Revenues from Western Canada’s oil, oil sands and gas producing regions accounted for approximately 80% of Flint’s revenues for the trailing twelve months from September 30, 2011, with the remaining 20% coming from the United States. Flint is expected to add approximately $3.5 billion to URS’ book of business upon closing. Following the close of the transaction, Flint will become a new division of URS, led by W. J. (Bill) Lingard, Flint’s President and Chief Executive Officer, as the Division President.

Martin M. Koffel, Chairman and Chief Executive Officer of URS, said, “Expanding our presence in the oil and gas sector has been a longstanding strategic priority for URS. Flint is one of North America’s leading fully integrated production and construction services providers to the oil and gas sector, with many long-duration construction contracts and multi-year maintenance agreements. Through this combination, URS will be well positioned in segments of the oil and gas industry that we expect to have attractive margins and growth rates. In addition, by joining with URS, Flint will be able to offer its base of multinational clients the full range of engineering, procurement and construction management services through URS’ existing operations.”

Stuart O’Connor, Chairman of Flint’s Board of Directors said, “We are very pleased with the arrangement with URS. It delivers a significant cash premium to our stockholders while also allowing Flint to accelerate the growth of its business by offering a more complete suite of services to clients.”

Mr. Lingard added, “Having access to URS’ pool of talented and experienced construction managers will allow Flint to oversee more projects simultaneously and drive revenue growth. Flint’s employees should also benefit from and enjoy more opportunities to work on a wider range of complex projects in both Canada and the United States. We look forward to working with our URS colleagues to achieve the exciting potential of the combination.”

H. Thomas Hicks, Chief Financial Officer of URS, said, “We expect this transaction will build significant long-term value for our stockholders. Flint offers a diversified, full cycle of services, has limited exposure to fixed price contracts and derives its earnings entirely from operations in the stable North American region. Assuming a second quarter close, we expect to achieve pre-tax cost synergies of US$10-$15 million in 2012, with additional savings expected in the following years as we benefit from economies of scale. We expect the transaction to be accretive to URS’ 2012 EPS between US$0.20 and US$0.30 per share, which reflects expected acquisition related costs, estimated amortization of intangible assets and the estimated cost synergies discussed above.”

URS has financing in place to complete the acquisition under its existing credit facility and a financing commitment for a new bridge facility. Permanent financing is expected to consist of borrowings under URS’ existing credit facility and new debt. Said Mr. Hicks, “URS intends, as in past acquisitions, to use its strong cash flows to reduce debt quickly, while retaining the flexibility to continue to invest in the business and, when debt levels have been reduced, pursue additional growth opportunities.”

URS Fiscal 2012 Outlook

On a standalone basis, URS expects that its fiscal 2012 revenues will be between $9.9 billion and $10.1 billion, net income will be between $292 and $300 million and EPS will be between $3.95 and $4.05. URS will provide full details about its financial results for 2011, and expectations for 2012, on its previously announced fourth quarter and full year 2011 earnings conference call on Monday, February 27, 2012.

The Arrangement

The acquisition will be implemented through a Plan of Arrangement under Canadian law and is subject to a number of customary conditions for a transaction of this nature including, but not limited to, the approval of at least 66 and 2/3% of the votes cast in person or by proxy by Flint shareholders and option holders at a special meeting of Flint's security holders, as well as court and relevant regulatory approvals. The terms and conditions of the arrangement and additional details of the transaction will be summarized in Flint’s management information circular, which is expected to be filed and mailed to Flint’s shareholders in early March 2012. A copy of the arrangement agreement will be filed on Flint’s SEDAR profile and will be available for viewing at www.sedar.com. The special meeting of Flint security holders is scheduled to be held on April 3, 2012, with closing expected to occur in the second quarter of 2012.

The arrangement agreement is subject to customary non-solicit provisions and Flint’s right to consider and accept superior proposals. In the event of a superior proposal, URS will have a five-business-day right to match the superior proposal. If the arrangement is not completed as a result of a superior proposal, or for other certain specified circumstances, a termination fee equal to C$42 million will be paid by Flint to URS.

After receiving financial and legal advice, the members of the Board of Directors of Flint voting on the resolution unanimously determined that the arrangement is in the best interests of Flint, and resolved to support the arrangement and to recommend that its shareholders and option holders vote in favor of the arrangement. The financial advisor to Flint’s Board of Directors has provided an opinion that subject to the assumptions, limitations and qualifications set forth therein, the consideration to be received by holders of common shares pursuant to the arrangement is fair, from a financial point of view, to such holders.

All of the members of Flint’s Board of Directors and certain senior officers and certain related shareholders, who collectively own approximately 8% of the outstanding Flint shares, have agreed to vote their shares in favor of the acquisition.

In respect of the forward-looking statements and information concerning the anticipated completion of the proposed Arrangement and the anticipated timing for completion of the Arrangement, Flint has provided such in reliance on certain assumptions that it believes are reasonable at this time, including assumptions as to the time required to prepare and mail Flint securityholder meeting materials, including the required information circular; the ability of the parties to receive, in a timely manner, the necessary regulatory, court, securityholder and other third party approvals, including but not limited to the Investment Canada Act approval and the ability of the parties to satisfy, in a timely manner, the other conditions to the closing of the Arrangement.

GAAP and IFRS Financial Measures

Flint’s historical financial statements for its fiscal year ended December 31, 2010, were prepared in accordance with Canadian generally accepted accounting principles and its 2011 subsequent fiscal quarters were prepared in accordance with the International Financial Reporting Standards 1, First time Adoption of International Financial Reporting Standards, and with International Accounting Standard (“IAS”) 34, Interim Financial Reporting, as issued by the International Accounting Standards Board (“IASB”). All pro forma combined financial information is based upon a combination of URS’ historical financial statements prepared in accordance with United States generally accepted accounting principles (GAAP) and Flint’s historical financial statements prepared in accordance with IFRS. Flint has not reconciled its historical financial statements to U.S. GAAP.

This release also contains prospective financial measures that are not calculated in accordance with GAAP, including prospective estimated acquisition costs, estimated amortization of intangible assets and estimated cost synergies. Management does not believe it is able to reconcile this information without unreasonable effort. URS’ management believes that these U.S. non-GAAP financial measures provide meaningful supplemental information regarding the expected benefits of the acquisition to investors in URS.
