                                    CAUTION!

                                DO NOT BE MISLED.

Dear Fellow Shareholder:

You may have received proxy materials from MMI, a recent investor in Simpson,
seeking your support for the election of their hand-picked nominees as directors
and their proposal to throw the Company up for sale. DO NOT BE MISLED BY WHAT WE
BELIEVE TO BE THEIR INACCURATE AND SELF-SERVING ANALYSIS OF SIMPSON AND ITS
POSITION IN THE AUTOMOTIVE PARTS INDUSTRY.

DO NOT RETURN ANY BLUE PROXY OR VOTING FORM SENT TO YOU BY MMI.

YOU MAY RECEIVE TELEPHONE CALLS AND REPEATED MAILINGS FROM THEM OR THEIR PAID
AGENTS. WE URGE YOU TO IGNORE THEIR REQUESTS FOR YOUR VOTE.


We will be sending Simpson's annual report and proxy materials for the April
18th Meeting shortly. It will include information that we believe you need to
make an informed choice at this year's meeting. PLEASE WAIT UNTIL YOU RECEIVE
THESE MATERIALS AND THE WHITE PROXY BEFORE CASTING YOUR VOTE. DO NOT BE RUSHED
INTO A VOTING DECISION WITHOUT HAVING ALL THE NECESSARY FACTS.

Thank you for your attention and continuing support.

Sincerely,


/s/ Roy E. Parrott
