Dear Customers,

On November 14, 2006, customers should have received a memo from CSI Technologies Inc. announcing the acquisition of certain optical fiber assembly and cable assembly product lines from the Emerson Network Power group. We asked you to update your accounts payable system to reflect our new name, address and payment details:

CSI Technologies Inc.
P.O. Box 5847
McAllen, Texas 78502-5847

For wire transfers / ACH, the Bank One account has been deactivated and the new account is established with:

Wells Fargo Bank
120 W. Nolana, McAllen, TX 78504
Please call us for account number details.

For those customers who have completed the information conversion, we thank you. For those customers who have not yet changed the information in your systems, we ask you to do so now to prevent service or payment delays. Should you have any questions relating to payments, credits and general details on your account, please call me at 956-683-3204. If you have questions about the transfer of our business from Emerson Network Power, please contact:

Customer Care Center, Baltimore
