GLASS LEWIS RECOMMENDS TOLLGRADE SHAREHOLDERS VOTE THE WHITE
PROXY CARD IN SUPPORT OF ALL TOLLGRADE BOARD NOMINEES

REPORT ACKNOWLEDGES THE TOLLGRADE BOARD FOR
BEING PROACTIVE IN TRANSFORMING THE COMPANY

PITTSBURGH, July 24, 2009 — Tollgrade Communications, Inc. (NASDAQ: TLGD) today announced that Glass Lewis & Co., a leading independent proxy advisory service, has recommended to its clients that shareholders vote for all of Tollgrade’s nominees to its Board of Directors at Tollgrade’s Annual Meeting of Shareholders to be held on August 5, 2009. Glass Lewis’ clients include institutional investors, mutual funds, pension funds and other fiduciaries.

In recommending that shareholders vote for all of Tollgrade’s director nominees, Glass Lewis recognized the Tollgrade Board for acting proactively over the past two years to reposition the Company, including its completion of a thorough strategic review process and the appointment of new executive leadership. In particular, Glass Lewis took note of Tollgrade’s leadership changes that resulted in Joseph A. Ferrara being named Chief Executive Officer and the strategy that Mr. Ferrara spearheaded to refocus Tollgrade’s core business by emphasizing its service assurance offerings to the telecom market. The Glass Lewis report noted that Tollgrade’s share price has performed well since the appointment of Mr. Ferrara as Chief Executive Officer in 2007 and since the announcement of the Company’s strategic review and new business strategy. The Glass Lewis report also noted that, given the actions taken by the Tollgrade Board to transform the Company and position it for long-term growth, future profitability, market leadership and increasing returns for investors, it did not believe that Ramius LLC had demonstrated that the Tollgrade Board required new outside representation.

Excerpts of Glass Lewis’ Proxy Analysis

On Ramius’ claims that the Tollgrade Board needs additional changes:

— “. . . [W]e do not believe that the dissident has successfully shown that the Board requires new outside representation at this time.”

On the Tollgrade Board’s proactive moves to reposition the Company:

— “. . . [W]e believe that the Tollgrade Board of Directors has acted proactively to help turn around the Company over the past two years. The Board has appointed new executive leadership and conducted a thorough strategic review process which resulted in the existing standalone operating strategy.”

On the Tollgrade Board’s appointment of distinguished telecom industry veterans Charles E. Hoffman and Edward H. Kennedy to serve as its newest independent directors:

— “. . . [t]he Board will likely benefit from the participation of the Company’s nominees given their industry experience.”

On Tollgrade’s stock price performance:

— “. . . [T]hough Tollgrade’s share price has declined it would be difficult to conclude that the Company’s share price has significantly underperformed.”

— “We note that the Company’s share price has performed well since the appointment of Mr. Ferrara as CEO in 2007 and since the announcement of the Company’s strategic review and new business strategy.”

— “Notably, Tollgrade’s share price has outperformed its peer indices under the tenure of Mr. Ferrara.”

— “Further, from the time of the announcement of the Company’s new strategic plan in October 2008 through July 17, 2009, Tollgrade’s stock has increased 45.7% while the Company peer index increased just 4.1%.“

“We are very pleased that a well-respected, independent third party such as Glass Lewis has carefully reviewed the voting alternatives and recommends that shareholders vote for all of Tollgrade’s director nominees,” said Joseph A. Ferrara, Tollgrade’s Chairman, Chief Executive Officer and President. “We are also gratified that Glass Lewis recognizes how proactive the Tollgrade Board has been in repositioning and transforming the Company. Given the substantial progress that Tollgrade has been achieving in effecting its transformation, it is unfortunate that Ramius seems steadfastly committed to continuing a distracting, disruptive and costly proxy contest that only serves to interfere with the progress we are making.”

Tollgrade urges all shareholders vote for their Board’s highly qualified nominees on the WHITE proxy card TODAY—by telephone, Internet, or by signing, dating and returning the WHITE proxy card. Shareholders that need assistance in voting their shares or have any questions are urged to call the company’s proxy solicitor, The Altman Group, Inc., Toll-Free at (866) 340-6685 or (201) 806-7300.
