CABLE DESIGN TECHNOLOGIES CORPORATION

     The undersigned stockholder of Cable Design Technologies Corporation hereby appoints Ferdinand C. Kuznik, William E. Cann and Charles B. Fromm as proxies, acting jointly and severally and with full power of substitution, for and in the name of the undersigned to vote at the Special Meeting of Stockholders to be held on [Month] [Day], 2004, beginning at 11:00 a.m., local time, at the Chicago O’Hare Marriott Suites, 6155 North River Road, Rosemont, IL 60018, and at any adjournments or postponements thereof, as directed, on the matters set forth in the accompanying Joint Proxy Statement/Prospectus and all other matters that may properly come before the Special Meeting, including, if submitted to the vote of the Cable Design Technologies Corporation stockholders, on a motion to adjourn or postpone the Special Meeting to another time and/or place for the purpose of soliciting additional proxies.

     Signing and dating this proxy card will have the effect of revoking any proxy card that you signed on an earlier date, and will constitute a revocation of all previously granted authority to vote for every proposal included on any proxy card.

     This proxy card when properly executed will be voted in the manner directed herein. If no choice is specified and the proxy is signed and returned, then the proxy will be voted “FOR” approval of each of Proposal 1, 2, 3 and 4 in the discretion of the proxies on any other matters as may properly come before the Special Meeting, except to the extent such discretionary authority is withheld below.

     The undersigned may revoke this proxy in one of three ways: (1) by sending to the Corporate Secretary of Cable Design Technologies Corporation an executed notice of revocation, (2) by sending to the Corporate Secretary of Cable Design Technologies Corporation a new, valid proxy bearing a later date or (3) by attending the Special Meeting and voting in person, which will automatically cancel any proxies previously given, or by revoking this proxy in person. Attendance at the Special Meeting will not by itself revoke this proxy. To be effective, any written notice of revocation or subsequent proxy must be received by the Corporate Secretary of Cable Design Technologies Corporation prior to the beginning of the Special Meeting. The written notice of revocation or subsequent proxy should be hand-delivered to the Corporate Secretary at the Special Meeting or sent to 1901 North Roselle Road, Schaumburg, IL 60195.

The Cable Design Technologies Corporation Board of Directors recommends a vote “FOR” Proposals 1, 2, 3
and 4.
