  Re:   Corrected Proxy Card for 2005 Annual Meeting of Shareholders

Dear Stoneridge Shareholder of Record:

You may have already received your proxy materials for Stoneridge’s 2005 Annual Meeting. As printing agent for Stoneridge we made an error printing the proxy card that was not discovered until after the annual report, proxy statement and proxy card had been mailed to you. Therefore, we are sending you the enclosed corrected proxy card, along with this explanation and an apology for any inconvenience our error may have caused you.

What Happened?

When we printed the proxy cards, we used a draft of the card which was not the final, approved draft.

What Is Different?

There are two changes in the corrected proxy card you are receiving with this letter. First, the named proxies for the Annual Meeting are Gerald V. Pisani, Joseph M. Mallak and Avery S. Cohen. Second, there are ten nominees for election of directors, including Jeffrey P. Draime, Douglas C. Jacobs and Gerald V. Pisani.

What Should You Do?

If you have already mailed your proxy card, Stoneridge will disregard it. We ask you to please mark, sign, date and return the enclosed corrected proxy card.

If you have not mailed your proxy card yet, please destroy the proxy card you received with the annual report and proxy statement and use the enclosed corrected proxy card instead.

We take full responsibility for this error and have borne all expenses associated with the reprinting and mailing of the corrected proxy card and the notification of shareholders of record.

Thank you for your understanding.
