          On July 26, 2007, Black Box Corporation (the “Company”), along with certain of its direct and indirect subsidiaries (collectively, the “Loan Parties”), the Lenders (defined below) and the Agent (defined below) entered into a waiver letter (the “Waiver”) with respect to the Second Amended and Restated Credit Agreement dated as of January 24, 2005, as amended (the “Credit Agreement”), by and among the Loan Parties, the lenders parties thereto (the “Lenders”) and Citizens Bank of Pennsylvania, as administrative agent for the Lenders (the “Agent”).

          Pursuant to the Waiver, the Agent and the Lenders waived until August 31, 2007 any defaults under the Credit Agreement resulting from the failure of the Loan Parties to timely deliver the Company’s audited financial statements and the related compliance certificate for its fiscal year ended March 31, 2007 and from the failure of the Company to timely file with the Securities and Exchange Commission its Annual Report on Form 10-K for such period.
