together with associated common stock purchase rights issued pursuant to the
Rights Agreement, dated as of February 1, 1990, as amended, between the Company
and American Stock Transfer & Trust Company as Rights Agent, are hereinafter
referred to as the "Shares"), at a price of $34.50 per Share, net to the seller
in cash (the "Purchase Price"), upon the terms and subject to the conditions set

         The Company will, upon the terms and subject to the conditions of the

for payment and the proration provisions. Certificates representing Shares not
purchased because of proration will be returned at the Company's expense. The

500,000 Shares pursuant to the Offer.

         THIS OFFER IS NOT CONDITIONED UPON ANY MINIMUM NUMBER OF SHARES BEING
TENDERED. THE OFFER IS, HOWEVER, SUBJECT TO CERTAIN OTHER CONDITIONS. SEE

         We are asking you to contact your clients for whom you hold Shares
registered in your name (or in the name of your nominee) or who hold Shares

         The Company will not pay any fees or commissions to any broker, dealer
or other person for soliciting tenders of Shares pursuant to the Offer. The
Company will, upon request, reimburse you for reasonable and customary handling
and mailing expenses incurred by you in forwarding materials relating to the
Offer to your customers. The Company will pay all stock transfer taxes
applicable to its purchase of Shares pursuant to the Offer, subject to
Instruction 6 of the Letter of Transmittal.

         In order to take advantage of the Offer, a duly executed and properly

confirmation of their book-entry transfer, all in accordance with the
instructions set forth in the Letter of Transmittal and the Offer to Purchase.

         As described in the Offer to Purchase, if more than 500,000 Shares (or
such greater number of Shares as the Company may elect to purchase pursuant to
the Offer) have been validly tendered and not withdrawn prior to the Expiration
Date (as defined in Section 1 of the Offer to Purchase) the Company will accept
Shares for purchase in the following order of priority: (i) all Shares validly
tendered and not withdrawn prior to the Expiration Date by any stockholder who
owned beneficially as of the close of business on November 23, 2001, and who
continues to own beneficially as of the Expiration Date, an aggregate of fewer
than 100 Shares and who validly tenders all of such Shares (partial tenders will
not qualify for this preference) and completes the box captioned "Odd Lots" in
the Letter of Transmittal and, if applicable, the Notice of Guaranteed Delivery;
and (ii) after purchase of all of the foregoing Shares, all other Shares validly
tendered and not withdrawn prior to the Expiration Date on a pro rata basis.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE OFFER. HOWEVER,
NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS MAKES ANY RECOMMENDATION TO
STOCKHOLDERS AS TO WHETHER TO TENDER


                                       2


SHARES OR REFRAIN FROM TENDERING THEIR SHARES. EACH STOCKHOLDER MUST MAKE THE
DECISION WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER. THE
COMPANY HAS BEEN ADVISED THAT CERTAIN OF ITS DIRECTORS OR EXECUTIVE OFFICERS
INTEND TO TENDER UP TO 195,000 SHARES PURSUANT TO THE OFFER. THE COMPANY,
HOWEVER, DOES NOT KNOW AT THIS TIME THE ACTUAL NUMBER OF SHARES THAT SUCH
PERSONS WILL TENDER PURSUANT TO THE OFFER. SEE SECTION 10.
