These four directors will be on URS' slate of directors nominated for election to the Board of Directors at the Company's 2014 Annual Meeting, along with eight incumbents, pursuant to an agreement with JANA Partners LLC. The four new directors will be: Diane C. Creel, William H. Schumann, III, David N. Siegel and V. Paul Unruh. Biographical information on the new directors is provided below. Current directors [A] and [B] have advised the Company that they do not plan to stand for re-election at the 2014 Annual Meeting.

Under the agreement with JANA, URS will also form a Value Creation Committee of the Board that will evaluate all options for enhancing shareholder value, including by engaging an investment bank to conduct a strategic review of the Company's business segments, operations and capital structure, and reviewing the Company's management compensation structure to enhance alignment with shareholder value creation. The Committee will be comprised of four members, two of whom will be new directors. Martin M.

Koffel continued: "With [A]'s and [B]'s decisions to stand down and the expansion of our Board, we are adding four new, highly qualified independent directors to the Board on March 27 and we will nominate these directors for election at the 2014 Annual Meeting.

As previously disclosed, the URS Board has been engaged in succession planning for the Company's Chief Executive Officer position and has appointed a CEO Succession Committee comprised of independent directors. Two of the new directors will promptly be appointed to this Committee. One of the new directors will also be appointed to the Compensation Committee.
