CONDITIONAL TENDER

(See Instruction 9)

     A tendering stockholder may condition his or her tender of Shares upon Engelhard purchasing a specified minimum number of the Shares tendered, as described in Section 6 of the Offer to Purchase. Unless Engelhard purchases at least the minimum number of Shares you indicate below pursuant to the terms of the Offer, Engelhard will not purchase any of the Shares tendered below. It is the tendering stockholder’s responsibility to calculate that minimum number, and we urge each stockholder to consult his or her own tax advisor in doing so. Unless you check the box immediately below and specify, in the space provided, a minimum number of Shares that Engelhard must purchase from you if Engelhard purchases any Shares from you, Engelhard will deem your tender unconditional.

     [  ] The minimum number of Shares that Engelhard must purchase from me if Engelhard purchases any Shares from me, is: __________ Shares.

     If, because of proration, Engelhard will not purchase the minimum number of Shares from you that you designate, Engelhard may accept conditional tenders by random lot, if necessary to purchase the number of Shares sought in the Offer. However, to be eligible for purchase by random lot, the tendering stockholder must tender all of his or her Shares. To certify that you are tendering all of the Shares you own, check the box below.

Ladies and Gentlemen:

     The undersigned hereby tenders to Engelhard Corporation, a Delaware corporation (“Engelhard”), the above-described shares of Engelhard’s common stock, par value $1.00 per share (the “Shares”), including the associated Series A Junior Preferred Stock Purchase Rights (the “Rights”), issued under the Rights Agreement, dated as of October 1, 1998, between Engelhard and ChaseMellon Shareholder Services, L.L.C., as Rights Agent, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated May 5, 2006, and in the related Letter of Transmittal (which together, as they may be amended and supplemented from time to time constitute the “Offer”). Engelhard is inviting its stockholders to tender their Shares at $45.00 per Share (the “Purchase Price”) net to the seller in cash, without interest, upon the terms and subject to the conditions of the Offer. Unless the associated Rights are redeemed prior to the expiration of the Offer, a tender of any Shares will also constitute a tender of the associated Rights. Engelhard will not pay any separate consideration for the Rights.

     The tender of the Shares is being made at the price per Share of $45.00, net to the seller in cash, without interest, on the terms and subject to the conditions set forth in this Letter of Transmittal and in Engelhard’s Offer to Purchase, dated May 5, 2006, receipt of which is hereby acknowledged.

     Subject to and effective upon acceptance for payment of, and payment for, Shares tendered with this Letter of Transmittal in accordance with the terms of the Offer, the undersigned hereby (1) sells, assigns and transfers to or upon the order of Engelhard all right, title and interest in and to all of the Shares tendered hereby which are so accepted and paid for; (2) orders the registration of any Shares tendered by book-entry transfer that are purchased under the Offer to or upon the order of Engelhard; and (3) appoints the depositary as attorney-in-fact of the undersigned with respect to such Shares, with the full knowledge that the depositary also acts as the agent of Engelhard, with full power of substitution (such power of attorney being an irrevocable power coupled with an interest), to perform the following functions:

(a)	deliver certificates for Shares, or transfer ownership of such Shares on the account books maintained by the book-entry transfer facility, together in either such case with all accompanying evidences of transfer and authenticity, to or upon the order of Engelhard, upon receipt by the depositary, as the undersigned’s agent, of the Purchase Price with respect to such Shares;
(b)	present certificates for such Shares for cancellation and transfer on Engelhard’s books; and
(c)	receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares, subject to the next paragraph, all in accordance with the terms of the Offer.

     The undersigned understands that Engelhard, upon the terms and subject to the conditions of the Offer, will pay $45.00 per Share for Shares validly tendered into, and not validly withdrawn from, the Offer subject to the conditions of the Offer and the proration and conditional tender provisions described in the Offer to Purchase.

     The undersigned hereby covenants, represents and warrants to Engelhard that:

(a)	the undersigned has a net long position in the Shares at least equal to the number of Shares being tendered within the meaning of Rule 14e-4 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is tendering the Shares in compliance with Rule 14e-4 under the Exchange Act;
(b)	has full power and authority to tender, sell, assign and transfer the Shares tendered hereby;
(c)	when and to the extent Engelhard accepts the Shares for purchase, Engelhard will acquire good and marketable title to them, free and clear of all security interests, liens, restrictions, claims, charges, encumbrances, conditional sales agreements or other obligations relating to their sale or transfer, and the Shares will not be subject to any adverse claims or rights;
(d)	the undersigned will, upon request, execute and deliver any additional documents deemed by the depositary or Engelhard to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby and accepted for purchase; and
(e)	the undersigned has read and agrees to all of the terms of the Offer.

     The undersigned understands that tendering of Shares under any one of the procedures described in Section 3 of the Offer to Purchase and in the Instructions to this Letter of Transmittal will constitute an agreement between the undersigned and Engelhard upon the terms and subject to the conditions of the Offer. The undersigned acknowledges that under no circumstances will Engelhard pay interest on the Purchase Price.

     The undersigned recognizes that under certain circumstances set forth in the Offer to Purchase, Engelhard may terminate or amend the Offer; or may postpone the acceptance for payment of, or the payment for, Shares tendered, or may accept for payment fewer than all of the Shares tendered hereby. The undersigned understands that certificate(s) for any Shares not tendered or not purchased will be returned to the undersigned at the address indicated above.

     The names and addresses of the registered holders should be printed, if they are not already printed above, exactly as they appear on the certificates representing Shares tendered hereby. The certificate numbers, the number of Shares represented by such certificates, and the number of Shares that the undersigned wishes to tender, should be set forth in the appropriate boxes above.

     Unless otherwise indicated under “Special Payment Instructions,” please issue the check for the aggregate Purchase Price of any Shares purchased (less the amount of any federal income or backup withholding tax required to be withheld), and/or return any Shares not tendered or not purchased, in the name(s) of the undersigned or, in the case of Shares tendered by book-entry transfer, by credit to the account at the book-entry transfer facility designated above. Similarly, unless otherwise indicated under “Special Delivery Instructions,” please mail the check for the aggregate Purchase Price of any Shares purchased (less the amount of any federal income or backup withholding tax required to be withheld), and any certificates for Shares not tendered or not purchased (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned’s signature(s). In the event that both the “Special Payment Instructions” and the “Special Delivery Instructions” are completed, please issue the check for the aggregate Purchase Price of any Shares purchased (less the amount of any federal income or backup withholding tax required to be withheld) and mail said check to the person(s) so indicated.

     The undersigned recognizes that Engelhard has no obligation, under the Special Payment Instructions, to transfer any certificate for Shares from the name of its registered holder, or to order the registration or transfer of Shares tendered by book-entry transfer.

     All authority conferred or agreed to be conferred in this Letter of Transmittal shall survive the death or incapacity of the undersigned and any obligations or duties of the undersigned under this Letter of Transmittal shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

INSTRUCTIONS TO LETTER OF TRANSMITTAL

Forming Part of the Terms of the Offer

1. Guarantee of Signatures.

Except as otherwise provided in this Instruction, all signatures on this Letter of Transmittal must be guaranteed by a financial institution that is a participant in the Securities Transfer Agents Medallion Program or a bank, broker, dealer, credit union, savings association or other entity which is an “eligible guarantor institution” as such term is defined in Rule 17Ad-15 under the Exchange Act (an “Eligible Institution”). Signatures on this Letter of Transmittal need not be guaranteed if either (a) this Letter of Transmittal is signed by the registered holder(s) of the Shares (which term, for purposes of this Letter of Transmittal, shall include any participant in the book-entry transfer facility whose name appears on a security position listing as the owner of Shares) tendered herewith and such holder(s) have not completed either the box entitled “Special Payment Instructions” or “Special Delivery Instructions” in this Letter of Transmittal; or (b) such Shares are tendered for the account of an Eligible Institution. See Instruction 6. You may also need to have any certificates you deliver endorsed or accompanied by a stock power, and the signatures on these documents may also need to be guaranteed. See Instruction 6.

2. Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery Procedures.

You should use this Letter of Transmittal only if you are (a) forwarding certificates with this Letter of Transmittal, (b) going to deliver certificates under a notice of guaranteed delivery previously sent to the depositary or (c) causing the Shares to be delivered by book-entry transfer pursuant to the procedures set forth in Section 3 of the Offer to Purchase. In order for you to validly tender Shares, the depositary must receive certificates for all physically tendered Shares, or a confirmation of a book-entry transfer of all Shares delivered electronically into the depositary’s account at the book-entry transfer facility, together in each case with a properly completed and duly executed Letter of Transmittal, or an Agent’s Message in connection with book-entry transfer, and any other documents required by this Letter of Transmittal, at one of its addresses set forth in this Letter of Transmittal by the Expiration Date (as defined in the Offer to Purchase).

The term “Agent’s Message” means a message transmitted by the book-entry transfer facility to, and received by, the depositary, which states that the book-entry transfer facility has received an express acknowledgment from the participant in the book-entry transfer facility tendering the Shares, that the participant has received and agrees to be bound by the terms of the Letter of Transmittal, and that Engelhard may enforce this agreement against the participant.

Guaranteed Delivery. If you cannot deliver your Shares and all other required documents to the depositary, or if your share certificates are not immediately available, by the Expiration Date, or the procedure for book-entry transfer cannot be completed on a timely basis, you may tender your Shares, pursuant to the guaranteed delivery procedure described in Section 3 of the Offer to Purchase, by or through any eligible institution. To comply with the guaranteed delivery procedure, you must (1) properly complete and duly execute a notice of guaranteed delivery substantially in the form provided to you by Engelhard, including (where required) a Signature Guarantee by an eligible institution in the form set forth in the notice of guaranteed delivery; (2) arrange for the depositary to receive the notice of guaranteed delivery by the Expiration Date; and (3) ensure that the depositary receives the certificates for all physically tendered Shares or book-entry confirmation of electronic delivery of Shares, as the case may be, together with a properly completed and duly executed Letter of Transmittal with any required signature guarantees or an Agent’s Message, and all other documents required by this Letter of Transmittal, within three New York Stock Exchange trading days after receipt by the depositary of such notice of guaranteed delivery, all as provided in Section 3 of the Offer to Purchase.

The notice of guaranteed delivery may be delivered by hand, facsimile transmission or mail to the depositary and must include, if necessary, a guarantee by an eligible guarantor institution in the form set forth in such notice. For Shares to be validly tendered under the guaranteed delivery procedure, the depositary must receive the notice of guaranteed delivery before the Expiration Date.

The method of delivery of all documents, including certificates for Shares, is at the option and risk of the tendering stockholder. If you choose to deliver the documents by mail, we recommend that you use registered mail with return receipt requested, properly insured. In all cases, please allow sufficient time to assure timely delivery.

Except as specifically permitted by Section 6 of the Offer to Purchase, Engelhard will not accept any alternative, conditional or contingent tenders, nor will it purchase any fractional Shares. By executing this Letter of Transmittal, you waive any right to receive any notice of the acceptance for payment of your tendered Shares.

3. Inadequate Space.

If the space provided in the box captioned “Description of Shares Tendered” is inadequate, then you should list the certificate numbers, the number of Shares represented by the certificate(s) and the number of Shares tendered with respect to each certificate on a separate signed schedule attached to this Letter of Transmittal.

4. Partial Tenders and Unpurchased Shares.

(Not applicable to stockholders who tender by book-entry transfer.) If you wish to tender (i.e., offer to sell) fewer than all of the Shares evidenced by any certificate(s) that you deliver to the depositary, fill in the number of Shares that you wish to tender (i.e., offer for sale) in the column entitled “Number of Shares Tendered.” In this case, if Engelhard purchases some but not all of the Shares that you tender, Engelhard will issue to you a new certificate for the unpurchased Shares. The new certificate will be sent to the registered holder(s) as promptly as practicable after the Expiration Date. Unless you indicate otherwise, all Shares represented by the certificate(s) listed and delivered to the depositary will be deemed to have been tendered. In the case of Shares tendered by book-entry transfer at the book-entry transfer facility, any tendered but unpurchased Shares will be credited to the appropriate account maintained by the tendering stockholder at the book-entry transfer facility. In each case, Shares will be returned or credited without expense to the stockholder.

5. Order of Purchase in the Event of Proration.

As described in Section 1 of the Offer to Purchase, stockholders may specify the order in which their Shares are to be purchased in the event that, as a result of proration or otherwise, Engelhard purchases some but not all of the tendered Shares pursuant to the terms of the Offer. The order of purchase may have an effect on the federal income tax treatment of any gain or loss on the Shares that Engelhard purchases. See Sections 1, 6 and 14 of the Offer to Purchase.

6. Signatures on Letter of Transmittal, Stock Powers and Endorsements.

     a. Exact Signatures. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the certificate(s) without any change whatsoever.

     b. Joint Holders. If the Shares are registered in the names of two or more persons, ALL such persons must sign this Letter of Transmittal.

     c. Different Names on Certificates. If any tendered Shares are registered in different names on several certificates, you must complete, sign and submit as many separate letters of transmittal as there are different registrations of certificates.

     d. Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificate(s) representing such Shares or separate stock powers are required unless payment of the Purchase Price is to be made, or the certificates for Shares not tendered or tendered but not purchased are to be issued, to a person other than the registered holder(s). Signature(s) on any such certificate(s) or stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, or if payment is to be made to a person other than the registered holder(s), the certificate(s) for the Shares must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificate(s) for such Shares, and the signature(s) on such certificates or stock power(s) must be guaranteed by an Eligible Institution. See Instruction 1.

If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or any other person acting in a fiduciary or representative capacity, such person should so indicate when signing and must submit to the depositary evidence satisfactory to Engelhard that such person has authority so to act.

7. Stock Transfer Taxes.

Except as provided in this Instruction 7, no stock transfer tax stamps or funds to cover such stamps need to accompany this Letter of Transmittal. Engelhard will pay or cause to be paid any stock transfer taxes payable on the transfer to it of Shares purchased in the Offer. If, however:

a.	payment of the Purchase Price is to be made to any person other than the registered holder(s);
	OR
b.	tendered certificates are registered in the name of any person(s) other than the person(s) signing this Letter of Transmittal,

then the depositary will deduct from the Purchase Price the amount of any stock transfer taxes (whether imposed on the registered holder(s), such other person(s) or otherwise) payable on account of the transfer of cash or stock thereby made to such person, unless satisfactory evidence of the payment of such taxes or an exemption from them is submitted with this Letter of Transmittal.

8. Special Payment and Delivery Instructions. If any of the following conditions holds:

a.	check(s) for the Purchase Price of any Shares purchased pursuant to the Offer are to be issued to a person other than the person(s) signing this Letter of Transmittal; or
b.	check(s) for the Purchase Price are to be sent to any person other than the person signing this Letter of Transmittal, or to the person signing this Letter of Transmittal, but at a different address,

then, in each such case, you must complete the boxes captioned “Special Payment Instructions” and/or “Special Delivery Instructions” as applicable in this Letter of Transmittal and make sure that the signatures herein are guaranteed as described in Instructions 1 and 6.

9. Conditional Tenders.

As described in Sections 1 and 6 of the Offer to Purchase, stockholders may condition their tenders on Engelhard’s purchasing all of their Shares or specify a minimum number of Shares that Engelhard must purchase for the tender of any of their Shares to be effective. If you wish to make a conditional tender you must indicate this choice in the box entitled “Conditional Tender” in this Letter of Transmittal or, if applicable, the notice of guaranteed delivery; and you must calculate and appropriately indicate, in the space provided, the minimum number of Shares that Engelhard must purchase if Engelhard purchases any Shares.

As described in Sections 1 and 6 of the Offer to Purchase, proration may affect whether Engelhard accepts conditional tenders. Proration may result in all of the Shares tendered pursuant to a conditional tender being deemed to have been withdrawn, if Engelhard could not purchase the minimum number of Shares required to be purchased by the tendering stockholder due to proration. If, because of proration, Engelhard will not purchase the minimum number of Shares that you designate, Engelhard may accept conditional tenders by random lot, if necessary to purchase the total number of Shares sought in the Offer. However, to be eligible for purchase by random lot, you must have tendered all of your Shares and must have checked the box so indicating. Upon selection by random lot, if any, Engelhard will limit its purchase in each case to the designated minimum number of Shares.

All tendered Shares will be deemed unconditionally tendered unless the “Conditional Tender” box is checked and appropriately completed. When deciding whether to tender Shares conditionally, we urge each stockholder to consult his or her own tax advisor.

10. Tax Identification Number and Backup Withholding.

Important Tax Information. U.S. federal income tax laws generally require a tendering stockholder to provide the depositary with such holder’s correct taxpayer identification number (“TIN”) and certain other information on the Substitute Form W-9, which is provided below, or, alternatively, to establish another basis for exemption from backup withholding. In addition to penalties, failure to provide the depositary with the correct information or an adequate basis for an exemption from backup withholding may result in backup withholding at a current rate of 28% on all payments made to stockholders or other payees pursuant to the Offer. Any amounts withheld under the backup withholding rules will be allowed as a credit against the stockholder’s U.S. federal income tax liability. If withholding results in an overpayment of taxes, the stockholder may obtain a refund if the required information is timely provided to the IRS.

In order to avoid backup withholding, each tendering stockholder that is a U.S. person (including a U.S. resident alien) must provide (i) its correct TIN by completing the Substitute Form W-9, certifying, under penalties of perjury, (1) that the TIN provided is correct (or that such stockholder is awaiting a TIN), (2) that (A) the stockholder is exempt from backup withholding, (B) the IRS has not notified the stockholder that such stockholder is subject to backup withholding as a result of a failure to report all interest or dividends or (C) the IRS has notified the stockholder that such stockholder is no longer subject to backup withholding, and (3) that the stockholder is a U.S. person (including a U.S. resident alien), or (ii), if applicable, an adequate basis for exemption. If the tendering stockholder has not been issued a TIN and has applied for one or intends to apply for one in the near future, such stockholder should write “Applied For” in the space provided for the TIN in Part I of the Substitute Form W-9, and sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number. If “Applied For” is written in Part I and the Paying Agent is not provided with a TIN by the time of payment, the Paying Agent will withhold 28% from any payments made pursuant to the Offer.

Certain stockholders (including, among others, corporations and certain foreign persons) are not subject to these backup withholding and reporting requirements. Exempt U.S. Holders (as defined in Section 14 of the Offer to Purchase) should indicate their exempt status on the Substitute Form W-9. A tendering Non-U.S. Holder (as defined in Section 14 of the Offer to Purchase) may qualify as an exempt recipient by submitting to the depositary a properly completed IRS Form W-8BEN, Form W-8ECI or Form W-8IMY, as applicable (instead of a Substitute Form W-9), signed under penalties of perjury, attesting to such stockholder’s exempt status. In addition, as described in Section 3 of the Offer to Purchase, a tendering Non-U.S. Holder must submit the appropriate IRS Form W-8, properly completed, in order to avoid U.S. federal income tax withholding at a rate of 30% on any payments made to such Non-U.S. Holders pursuant to the Offer.

For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete the Substitute Form W-9 if Shares are held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.

FAILURE TO COMPLETE AND RETURN THE SUBSTITUTE FORM W-9 OR AN APPROPRIATE IRS FORM W-8 MAY RESULT IN WITHHOLDING ON ANY PAYMENTS MADE TO YOU PURSUANT TO THE OFFER.

11. Irregularities.

Engelhard will determine in its sole discretion all questions as to the number of Shares to accept, and the validity, eligibility (including time of receipt), and acceptance for payment of any tender of Shares. Any such determinations will be final and binding on all parties. Engelhard reserves the absolute right to reject any or all tenders of Shares it determines not be in proper form or the acceptance of which or payment for which may, in the opinion of Engelhard, be unlawful. Engelhard also reserves the absolute right to waive any of the conditions of the Offer and any defect or irregularity in the tender of any particular Shares, and Engelhard’s interpretation of the terms of the Offer, including these instructions, will be final and binding on all parties. No tender of Shares will be deemed to be properly made until all defects and irregularities have been cured or waived. Unless waived, any

defects or irregularities in connection with tenders must be cured within such time as Engelhard shall determine. None of Engelhard, the dealer managers, 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.

12. Questions; Requests for Assistance and Additional Copies.

Please direct any questions or requests for assistance or for additional copies of the Offer to Purchase, the Letter of Transmittal or the notice of guaranteed delivery to the information agent at the telephone number and address set forth below. You may also contact the dealer managers or your broker, dealer, commercial bank or trust company for assistance concerning the Offer.

13. Lost, Stolen, Destroyed or Mutilated Certificates.

If any certificate representing any Shares has been lost, stolen, destroyed or mutilated, you should notify Mellon Investor Services LLC, the transfer agent for the Shares (the “Transfer Agent”), by calling (201) 680-4860 and asking for instructions on obtaining replacement certificate(s) at the address specified on the cover of this Letter of Transmittal. The Transfer Agent will require you to complete an affidavit of loss and return it to the Transfer Agent. You will then be instructed by the Transfer Agent as to the steps you must take in order to replace the certificate. You may be required to post a bond to secure against the risk that the certificate may be subsequently recirculated.

We cannot process this Letter of Transmittal and related documents until you have followed the procedures for replacing lost, stolen, destroyed or mutilated certificates. We urge you to contact the Transfer Agent immediately, in order to receive further instructions, for a determination as to whether you will need to post a bond, and to permit timely processing of this documentation.

Important: The depositary must receive this Letter of Transmittal (together with certificate(s) for Shares or confirmation of book-entry transfer and all other required documents) or, if applicable, the notice of guaranteed delivery, before the Expiration Date (as defined in the Offer to Purchase).

14. Stock Option Plans.

Holders of vested (but unexercised) options to purchase Shares granted under the Stock Option Plans may exercise such options to the extent that Shares underlying such options (“Option Shares”) are tendered into and actually purchased in the Offer, such exercise to be effective at the time the underlying Option Shares are accepted for purchase in the Offer. Optionees who wish to exercise their options and tender the underlying Option Shares as described in the preceding sentence should not use this Letter of Transmittal. Rather, such optionees should follow the procedures set forth in the Letter to Optionees and the Notice of Instructions (Options) mailed to them with the Offer to Purchase. Alternatively, holders of vested (but unexercised) options to purchase Shares granted under the Stock Option Plans may exercise their options and tender the Option Shares received upon exercise using this Letter of Transmittal, just as is the case with Shares that are not Option Shares.

15. Dividend Reinvestment Plan.

If you desire to tender Shares credited to your account under the Dividend Reinvestment Plan, you should complete the provisions under the caption “Dividend Reinvestment Plan Shares” above. A participant in the Dividend Reinvestment Plan may complete such box on only one Letter of Transmittal submitted by such participant. If a shareholder tenders Shares held in the Dividend Reinvestment Plan, all such Shares credited to such shareholder’s account(s) (including any Shares purchased on or after March 31, 2006 and credited to such account(s), which are not reflected on the pre-addressed label included herewith) will be tendered, unless otherwise specified in the box entitled “Dividend Reinvestment Plan Shares.” In the event that the box captioned “Dividend Reinvestment Plan Shares” is not completed, no Shares held in the tendering shareholder’s Dividend Reinvestment Plan account will be tendered.

Exempt payees should complete a substitute Form W-9 to avoid possible erroneous backup withholding. Furnish your taxpayer identification number, check the appropriate box for your status, check the “Exempt from backup withholding” box, sign and date the form and return it to the payer. Foreign payees who are not subject to backup withholding should complete an appropriate IRS Form W-8 (or successor form) and return it to the payer.

Privacy Act Notice. Section 6109 requires you to provide your correct taxpayer identification number to payers who must file information returns with the IRS to report interest, dividends, and certain other income paid to you to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of your return and may also provide this information to various government agencies for tax enforcement or litigation purposes and to cities, states, and the District of Columbia to carry out their tax laws, and may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1) Failure to Furnish Taxpayer Identification Number. If you fail to furnish your correct taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information with Respect to Withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

(3) Criminal Penalty for Falsifying Information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
