May 15, 2007
Dear Terayon Stockholders:
Terayon Communication Systems, Inc. and Motorola, Inc. have agreed to a transaction in which Motorola, Inc. would acquire all of the outstanding shares of Terayon common stock for $1.80 per share in cash.
The pending transaction has been approved unanimously by Terayon’s Board of Directors. Once the transaction is approved by our stockholders, we have obtained the necessary regulatory clearances and all other closing conditions have been satisfied, we expect the transaction to be completed in the second or third quarter of 2007.
Naturally, we want to communicate with you about this important transaction, and a few questions and answers are included on the reverse side of this letter. On May 11, 2007, we filed a preliminary proxy statement with the Securities and Exchange Commission and, in due course, a definitive proxy statement will be filed and mailed directly to you together with a proxy card and voting instructions. When you receive the materials, we will be happy to answer any questions you may have.
The proxy statement will contain important information, which you are urged to review carefully. After you have had an opportunity to review the proxy statement, to consult with your financial advisor, and to ask whatever questions you may have about the transaction, you will be asked to vote on the proposed transaction.
On behalf of Terayon, I want to thank you for your continued confidence in our people, products and future service. Pending completion of the acquisition, we remain focused on our deliverables and objectives and will continue to add value to our company and our products. I encourage you to visit our website at to keep abreast of the latest updates.
/s/ Jerry D. Chase

Commonly Asked Questions and Answers about the Proposed Merger and
Special Meeting of Stockholders of Terayon Communication Systems, Inc.
The following is provided for your convenience and briefly addresses some commonly asked questions about the proposed merger with Motorola, Inc. and special meeting of Terayon stockholders. You should carefully read our proxy statement when you receive it in the mail.
Q:   What will Terayon stockholders be asked to vote on?
A:   You will be asked to consider and adopt a merger agreement and approve a merger, the result of which is that Motorola will acquire Terayon. After the merger, Terayon will become a wholly owned subsidiary of Motorola.
Q:   What will Terayon stockholders receive in the merger? What does Terayon’s Board of Directors recommend?
A:   In the merger, each issued and outstanding share of common stock of Terayon will be converted into the right to receive $1.80 in cash, without interest and less any required withholding tax (subject to the right of stockholders to seek appraisal of their shares under Delaware law). Terayon’s Board of Directors unanimously recommends that Terayon stockholders vote “FOR” the adoption of the merger agreement and approval of the merger.
Q:   When will the merger be completed and when will Terayon stockholders receive payment for their shares?
A:   We are working to complete the merger as quickly as possible and currently expect it will be completed in the second or third quarter of 2007, at which time you will receive payment for your shares (if you are a stockholder of record, you will have to surrender your stock certificate, along with a duly completed letter of transmittal, in order to receive payment). However, the merger cannot be completed without first receiving the approval of Terayon stockholders, clearance by various regulatory authorities and satisfaction of a number of other closing conditions.
Q:   When and where is the special meeting of stockholders to consider and act on the proposed merger? What happens if you do not vote on the merger?
A:   The date and location of the special meeting of stockholders will be announced in the near future and listed in a Notice of Meeting to be mailed directly to you along with the proxy statement. If you do not vote or if you abstain from voting on the merger, your actions will have the same effect as voting against the merger.
Q:   What do Terayon stockholders need to do now?
A:   You do not need to do anything now. Instead, you should simply wait to receive your proxy statement. Upon receipt, we urge you to read the proxy statement carefully and consider how the merger affects you. Also, at that time, you should ask whatever questions you may have about the merger. Then, you should cast your vote promptly to ensure that your wishes are reflected in the vote on the merger at the special meeting.
Q:   Who can be contacted with questions?
A:   If you have questions with respect to the proposed merger, you can contact MacKenzie Partners, which is assisting Terayon in connection with the proposed merger, toll-free at 1-800-322-2885.
