FOR IMMEDIATE RELEASE

GLASS LEWIS & CO. RECOMMENDS FEDERAL SIGNAL STOCKHOLDERS VOTE FOR
ALL THREE OF FEDERAL SIGNAL’S DIRECTOR NOMINEES ON THE WHITE PROXY
CARD

Second Leading Independent Proxy Advisory Firm Endorses Federal Signal’s Director Nominees

OAK BROOK, Ill., April 20 — Federal Signal Corporation (NYSE: FSS), a leader in advancing security and well-being, today announced that Glass Lewis & Co., a leading independent proxy advisory firm, recommends that Federal Signal stockholders support all three of the Company’s director nominees at Federal Signal’s 2009 Annual Meeting of Stockholders to be held on April 29, 2009.

As previously announced, RiskMetrics Group/ISS Governance Services, another leading independent proxy advisory firm, also recommended that Federal Signal stockholders vote FOR all the Board’s director nominees. Glass Lewis and RiskMetrics are widely recognized as the nation’s two leading independent proxy voting and corporate governance advisory firms. The analyses and recommendations of Glass Lewis and RiskMetrics are relied upon by hundreds of major institutional investment firms, mutual funds and fiduciaries throughout the United States.

In its April 20, 2009, report recommending that Federal Signal stockholders elect all three of the Board’s nominees, Glass Lewis stated that it “... believe[s] that the current board members have the appropriate background and independence to oversee the executive team and Company going forward and that the participation of the Dissident on the board is unwarranted at this time.”¹

Glass Lewis also states that new CEO, Bill Osborne, “has been in place for only a short time” and that “the board has a new strategic plan in place.”¹

“We are pleased that two of the nation’s leading independent proxy advisory firms - RiskMetrics and now Glass Lewis — recommend that Federal Signal stockholders vote FOR all the Board’s director nominees,” said John McCartney, an independent director speaking on behalf of Federal Signal’s Board. “Glass Lewis and RiskMetrics share our long-held belief that Federal Signal has the right plan and the right Board and management team to lead the Company and create stockholder value.”

As previously announced, RiskMetrics stated the following in its April 17, 2009 report recommending that Federal Signal stockholders elect all three of the Board’s nominees¹:

•

“... we note that since the removal of the previous management team in Dec. 2007, the company has not only performed largely in line with its peer group in terms of share price performance but also has substantially improved its operating metrics.”

	•		“With respect to election of three directors to a ten member classified board, we note that two of the three company nominees, Joseph Wright and William Osborne are new and joined the board in 2008. Moreover, five of the nine non-executive directors have been on the board since 2005 ... Meanwhile, Mr. Gerbsman, the third dissident nominee does not seem to have any direct industry/sector operating or public board experience.”
	•		“...we note that [Kanders] applied for the CEO position and only after his candidacy was turned down, he initiated the proxy contest. As such, even though Mr. Kanders has publicly stated that he is no longer interested in the CEO position and would work with the new management, we believe that the being ‘disruptive’ argument may have some merit in this case.”
	•		“Regarding the new management team, we note that analyst reports had a favorable opinion of Mr. Osborne at the time of his appointment.”

Federal Signal urges stockholders to follow the RiskMetrics and Glass Lewis recommendations by signing, dating and returning the WHITE proxy card today. For additional information on how to vote their shares, stockholders should call Innisfree M&A Incorporated, toll-free, at (877) 800-5186.
