If the Depositary is not provided with the correct TIN, the Internal Revenue Service may subject the shareholder or other payee to a $50 penalty. In addition, payments that are made to such shareholder or other payee with respect to Shares purchased pursuant to the Offer may be subject to 31% backup withholding. Certain shareholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements and should indicate their status by writing "exempt" across the face of the Substitute Form W-9. In order for a foreign individual to qualify as an exempt recipient, the shareholder must submit a Form W-8BEN, signed under penalties of perjury, attesting to that individual's exempt status. A Form W-8BEN can be obtained from the Depositary. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for more instructions. If backup withholding applies, the Depositary is required to withhold 31% of any such payments to be made to the shareholder or other payee. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained from the Internal Revenue Service, PROVIDED that the required information is given to the Internal Revenue Service. The box in Part 3 of the Substitute Form W-9 may be checked if the tendering shareholder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If the box in Part 3 is checked, the shareholder or other payee must also complete the Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that the box in Part 3 is checked and the Certificate of Awaiting Taxpayer Identification Number is completed, the Depositary will withhold 31% on all payments made prior to the time a properly certified TIN is provided to the Depositary. The shareholder is required to give the Depositary the TIN (e.g., social security number or employer identification number) of the record owner of the Shares or of the last transferee appearing on the transfers attached to, or endorsed on, the certificates evidencing the Shares. If the Shares are registered in more than one name or are not registered in the name of the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional guidance on which number to report. 8 PAYER'S NAME: EQUISERVE TRUST COMPANY -------------------------------------------------------------------------------------------------------------------- SUBSTITUTE PART 1--PLEASE PROVIDE YOUR TIN IN THE FORM W-9 BOX AT RIGHT AND CERTIFY BY SIGNING Social Security Number(s) AND DATING BELOW OR Employer Identification Number(s) ------------------------------------------------------------------------------------------- DEPARTMENT OF THE PART 2--Certification--Under penalties of perjury, I certify that: TREASURY (1) the number shown on this form is my correct Taxpayer PART 3-- INTERNAL REVENUE Identification Number (or I am waiting for a number to be Awaiting TIN SERVICE issued to me) and / / (2) I am not subject to backup withholding because (a) I am exempt -------------------- from backup withholding or (b) I have not been notified by the PART 4-- Internal Revenue Service (the "IRS") that I am subject to backup Exempt TIN withholding as a result of a failure to report all interest or / / dividends or (c) the IRS has notified that I am no longer subject to backup withholding. me ------------------------------------------------------------------------------------------- PAYER'S REQUEST FOR CERTIFICATION INSTRUCTIONS--You must cross out item (2) in Part 2 above if you have TAXPAYER been notified by the IRS that you are subject to backup withholding because of IDENTIFICATION under-reporting interest or dividends on your tax returns.

In all other cases, all signatures on this Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations, and brokerage houses) that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion Program (each such entity being hereinafter referred to as an "Eligible Institution"). See Instruction 5. 2. Delivery of Letter of Transmittal and Shares; Guaranteed Delivery Procedures. This Letter of Transmittal is to be used only if (a) certificates are to be forwarded with it to the Depositary or (b) delivery of Shares is to be made by book-entry transfer pursuant to the procedure set forth in Section 3 of the Offer to Purchase. Certificates for all physically delivered Shares, or a confirmation of a book-entry transfer of all Shares delivered electronically into the Depositary's account at DTC, together in each case with a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof), with any required signature guarantees, and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the front page of this Letter of Transmittal before the Expiration Date (as defined in the Offer to Purchase). Delivery of documents to DTC does not constitute delivery to the Depositary. Shareholders whose certificates are not immediately available (or who cannot follow the procedures for book-entry transfer on a timely basis) or who cannot transmit this Letter of Transmittal and all other required documents to reach the Depositary before the Expiration Date, may nevertheless tender their Shares pursuant to the guaranteed delivery procedure set forth in Section 3 of the Offer to Purchase. Pursuant to such procedure: (a) such tender must be made by or through an Eligible Institution, (b) the Depositary must receive (by hand, mail or facsimile transmission), before the Expiration Date, a properly completed and duly executed Notice of Guaranteed Delivery substantially in the form the Company has provided with the Offer to Purchase and (c) the certificates for all tendered Shares in proper form for transfer (or confirmation of a book-entry transfer of all such Shares into the Depositary's account at DTC), together with a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof) and any other documents required by this Letter of Transmittal, must be received by the Depositary within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in Section 3 of the Offer to Purchase. The method of delivery of all documents, including share certificates, the Letter of Transmittal and any other required documents, is at the election and risk of the tendering shareholder. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. No alternative, conditional or contingent tenders will be accepted, and no fractional Shares will be purchased. By executing this Letter of Transmittal (or a manually signed facsimile thereof), each tendering shareholder waives any right to receive any notice of the acceptance of such shareholder's tender. 3. Inadequate Space. If the space provided in the box entitled "Description of Shares Tendered" is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate signed schedule and attached to this Letter of Transmittal. 4. Partial Tenders and Unpurchased Shares. (Not applicable to shareholders who deliver Shares by book-entry transfer). If fewer than all the Shares evidenced by any certificate delivered to the Depositary are to be tendered, fill in the number of Shares that are to be tendered in the box entitled "Number of Shares Tendered". If such Shares are purchased, a new certificate for the remainder of the Shares evidenced by the old certificate(s) will be sent to and in the name of the registered holder(s) (unless otherwise specified by 10 such holder(s) having completed either of the boxes entitled "Special Delivery Instructions" or "Special Payment Instructions" on this Letter of Transmittal) as soon as practicable following the expiration or termination of the Offer. All Shares represented by the certificate(s) listed and delivered to the Depositary will be deemed to have been tendered unless otherwise indicated. 5. Signatures on Letter of Transmittal; Share Powers; and Endorsements. (a) If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered herewith, the signature(s) must correspond exactly with the name(s) as written on the face of the certificates without any change whatsoever. (b) If any of the Shares tendered herewith are registered in the names of two or more joint owners, each such owner must sign this Letter of Transmittal. (c) If any of the Shares tendered herewith are registered in different names on different certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates. (d) If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered herewith, no endorsements of certificates or separate share powers are required unless payment is to be made and/or certificates for Shares not tendered or not purchased are to be issued to a person other than the registered holder(s). If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered herewith, however, the certificates must be endorsed or accompanied by appropriate share powers, in either case, signed exactly as the name(s) of the registered holder(s) appear on the certificates for such Shares. Signatures on any such certificates or share powers must be guaranteed by an Eligible Institution. See Instruction 1. (e) If this Letter of Transmittal or any certificates or share powers are signed by a trustee, executor, administrator, guardian, attorney-in-fact, agent, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing and proper evidence satisfactory to the Company of the authority of such person so to act must be submitted. 6. Share Transfer Taxes. The Company will pay any share transfer taxes with respect to the transfer and sale of Shares to it or its order pursuant to the Offer. If, however, payment of the aggregate Purchase Price is to be made to, or certificates for Shares not tendered or accepted for purchase are to be registered in the name of, any person other than the registered holder, or if tendered certificates are registered in the name of any person other than the person(s) signing this Letter of Transmittal, the amount of any share transfer taxes (whether imposed on the registered holder or such person) payable on account of the transfer to such person will be deducted from the aggregate purchase price unless satisfactory evidence of payment of such taxes or exemption therefrom is submitted. 7. Odd Lots. As described in Sections 1 and 2 of the Offer to Purchase, if the number of Shares properly tendered and not withdrawn before the Expiration Date is greater than 1,500,000 (or such greater number of Shares as the Company may elect to purchase pursuant to the Offer), the Company, upon the terms and subject to the conditions of the Offer, will accept Shares for purchase first from all Shares properly tendered and not withdrawn before the Expiration Date by any shareholder who beneficially owned as of the close of business on August 14, 2000 and who continued to own beneficially until the Expiration Date an aggregate of fewer than 100 Shares, who tendered all Shares beneficially owned by such person (partial tenders of Shares will not qualify for this preference) and who completes the box captioned "Odd Lots" in this Letter of Transmittal and, if applicable, on the Notice of Guaranteed Delivery. This preference will not be available unless the box above entitled "Odd Lots" is completed. 8. Irregularities. All questions as to the number of Shares to be accepted and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by the Company, in its sole discretion, which determination shall be final and binding on all parties. The Company reserves the absolute right to reject any or all tenders determined by it not to be in proper form or the acceptance for payment of which may, in the opinion of the Company's counsel, be unlawful. The Company also reserves the absolute right to waive any of the conditions of the Offer (except as provided in 11 Section 12 of the Offer to Purchase) and any defect or irregularity in the tender of any particular Shares. The Company's interpretation of the terms and conditions of the Offer (including these instructions) shall be final and binding on all parties. No tender of Shares will be deemed properly made until all defects or irregularities have been cured or waived. None of the Company, the Depositary, the Information Agent or any other person is or will be obligated to give notice of any defects or irregularities in tenders, and none of them will incur any liability for failure to give any such notice. 9. Special Payment and Delivery Instructions. If the check for the aggregate Purchase Price of any Shares purchased is to be issued to, or any Shares not tendered or not purchased are to be returned in the name of, a person other than the person(s) signing this Letter of Transmittal or if the check or any certificates for Shares not tendered or not purchased are to be mailed to someone other than the person(s) signing this Letter of Transmittal or to the person(s) signing this Letter of Transmittal at an address other than that shown in the box entitled "Descriptions of Shares Tendered", the boxes entitled "Special Payment Instructions" and/or "Special Delivery Instructions" on this Letter of Transmittal should be completed. 10.

Non-U.S. Shareholder Withholding. Non-U.S. shareholders should note that the 30% U.S. withholding tax generally applicable to distributions by U.S. corporations should not apply to the proceeds payable pursuant to the Offer (however, as indicated above under "Important Tax Information", U.S. Federal backup withholding tax may be applicable). 12 Manually signed facsimile copies of this Letter of Transmittal, properly completed and duly executed, will be accepted.
