[text of a letter sent to certain Belden Communications Division customers] [BELDER LOGO] February 5, 2004 [Address of Customer] Subject: MERGER BETWEEN BELDEN CORPORATION AND CDT CORPORATION Dear ______, By now I am sure you have become aware of two press releases by Belden Corporation and CDT Corporation announcing their planned MERGER OF EQUALS which is expected to close sometime in the second quarter of this year. The combined company will be called BELDEN CDT INC. and will be headquartered in St. Louis, Missouri. Each of the two companies will have equal representation on the Board of the merged company. The current Chairman of CDT will become the Chairman of the new company, and the current CEO of Belden will become the CEO of the new company. Belden CDT Inc., with annual sales of approximately USD 1.3 billion will be among the world's largest manufacturers of copper communications cables as well as high-speed electronic cables and networking products. Belden CDT Inc. will have global presence with numerous manufacturing facilities in the U.S., Europe, and Canada (one in Pointe Claire, Quebec, one in Cobourg, Ontario). There will be no cash changing hands in the merger, consequently the cash balance of Belden CDT Inc. will not diminish. The new company will have 6 business Divisions as follows: - Specialty Products - West Penn Wire - Europe - Networking - Electronics Products - Communications Products The Communications Products Division with which you are most familiar will be managed by the same Senior Executives as follows: Robert Matz, President William Duckworth, VP Marketing and Sales Art Yaroch, VP Manufacturing Warren Stout, VP Finance At the level of the people who service the [customer name] account there will be no change either. The following will remain on their current assignments: Jack Basmadjian Strategic Relationship Pat Roy Regional Sales Manager, Quebec Ted Fulton Regional sales Manager, Ontario Leigh Bolger Manager, Customer Service Andre Picard Customer Service Representative Curtis Andre Customer Service Representative In summary, once the merger is closed it is going to be BUSINESS AS USUAL IN ALL RESPECTS between [customer name] and the Communications Products Division of Belden CDT Inc. Belden Corporation also announced today a STRATEGIC INITIATIVE in the form of a non-cash asset impairment charge in the amount of USD 92.8 million. This charge reflects the unbalance that has existed for the past few years between aggregate industry demand for copper cables versus supply (the latter exceeds demand). With this charge, the Balance Sheet of Belden's Communications Products Division has been STRENGTHENED CONSIDERABLY, and its overhead cost structure has been reduced significantly. As a result this strategic initiative will strengthen the Communications Product Division's financial strength going forward. As the outlook for aggregate cable demand remains soft for the foreseeable future, Belden will explore other strategic initiatives with a view to strengthening its financial and market position further. This will ensure that our customers will continue to rely on a SECURE AND COMPETITIVE SUPPLY OF COPPER CABLES from the Communications Products Division of Belden CDT Inc. Please do not hesitate to call one of the undersigned for further questions or clarification about this matter. Kind Regards, William D. Duckworth Jack Basmadjian VP, Marketing & Sales Senior Director, Marketing & PLM Belden Communications Division Belden Communications Canada 602-233-5100 514-697-5273 c.c. ________________ FORWARD-LOOKING STATEMENTS This filing contains, in addition to statements of historical fact, certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
