           INCORPORATION OF PRIOR REGISTRATION STATEMENTS BY REFERENCE

         Black Box Corporation, formerly known as MB Communications, Inc. (the
"Corporation"), hereby incorporates by reference into this Registration
Statement the information contained in the Corporation's earlier Registration
Statements, File Nos. 33-75254, 33-92656, 333-1978, 333-34839, 333-81521 and
333-64410 relating to the Corporation's 1992 Stock Option Plan and amendments
thereto.

         The financial statements included in the Annual Report on Form 10-K
incorporated herein by reference were audited by Arthur Andersen LLP. After
reasonable efforts, the Registrant has not been able to obtain the consent of
Arthur Andersen LLP to the incorporation by reference of its audit report dated
April 26, 2002 into this registration statement. Accordingly, Arthur Andersen
LLP will not be liable to investors under Section 11(a) of the Securities Act
because it has not consented to being named as an expert in this registration
statement, and therefore such lack of consent may limit the recovery by
investors from Arthur Andersen LLP.

Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Lawrence, Commonwealth of Pennsylvania, on this
