Delivery of this letter of transmittal to an address, or transmission via telegram, telex or facsimile, other than to the exchange agent as set forth above, will not constitute a valid delivery. The method of delivery of all documents, including certificates, is at the risk of the holder. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service. If delivery is by mail, we recommend the use of registered mail with return receipt requested, properly insured. In all cases, you should allow sufficient time to assure delivery to the exchange agent before the Expiration Date.

The undersigned acknowledges that he or she has received the prospectus dated , 2013 of NewMarket Corporation and this letter of transmittal and the instructions hereto, which together constitute NewMarket Corporation’s offer to exchange (the “Exchange Offer”) $350,000,000 aggregate principal amount of 4.100% Senior Notes due 2022 that were issued on December 20, 2012 and have not been registered under the Securities Act for 4.100% Senior Notes due 2022 that have been registered under the Securities Act, pursuant to a registration statement of which the prospectus is a part. Whenever we refer herein to the 4.100% Senior Notes due 2022 that were issued on December 20, 2012 and have not been registered under the Securities Act, we refer to them as the “initial notes.” Whenever we refer herein to the 4.100% Senior Notes due 2022 that have been registered under the Securities Act, we refer to them as the “exchange notes.” The term “Expiration Date” shall mean 5:00 p.m., New York City time, on , 2013, unless NewMarket Corporation, in its sole discretion, extends the Exchange Offer, in which case the term shall mean the latest date and time to which the Exchange Offer is extended. All other terms used but not defined herein have the meaning given to them in the prospectus.

The initial notes have the following CUSIP numbers: 651587 AD9 and U64788 AB5.

Delivery of documents to The Depository Trust Company (“DTC”) does not constitute delivery to the exchange agent.

The term “Holder” as used herein means any person in whose name initial notes are registered on the books of NewMarket Corporation or any other person who has obtained a properly completed bond power from the registered holder.

Any Holder of initial notes who wishes to tender his, her or its initial notes must, prior to the Expiration Date, either: (a) complete, sign and deliver this letter of transmittal, or a facsimile thereof, to the exchange agent in person or to the address or facsimile number set forth above and tender (and not withdraw) his, her or its initial notes, or (b) if a tender of initial notes is to be made by book-entry transfer to the account maintained by the exchange agent at DTC, confirm such book-entry transfer, including the delivery of an agent’s message (a “Book-Entry Confirmation”), in each case in accordance with the procedures for tendering described in the instructions to this letter of transmittal.

Holders of initial notes whose certificates are not immediately available or who are unable to deliver their certificates or Book -Entry Confirmation and all other documents required by this letter of transmittal to be delivered to the exchange agent on or prior to the Expiration Date must tender their initial notes according to the guaranteed delivery procedures set forth under the caption “The Exchange Offer—Procedures for Tendering—Guaranteed Delivery Procedures” in the prospectus. (See Instruction 1.)

Upon the terms and subject to the conditions of the Exchange Offer, the acceptance for exchange of the initial notes validly tendered and not withdrawn and the issuance of the exchange notes will be made promptly following the Expiration Date.

Subject to the terms and conditions of the Exchange Offer, the undersigned hereby tenders to NewMarket Corporation the principal amount of initial notes indicated above. Subject to and effective upon the acceptance for exchange of the principal amount of initial notes tendered hereby in accordance with this letter of transmittal and the accompanying instructions, the undersigned sells, assigns and transfers to, or upon the order of, NewMarket Corporation all right, title and interest in and to the initial notes tendered hereby. The undersigned hereby irrevocably constitutes and appoints the exchange agent its agent and attorney-in-fact (with full knowledge that the exchange agent also acts as agent of NewMarket Corporation and as trustee under the indenture for the initial notes and the exchange notes) with respect to the tendered initial notes with full power of substitution to (i) deliver certificates for such initial notes to NewMarket Corporation, or transfer ownership of such initial notes on the account books maintained by DTC, together with all accompanying evidences of transfer and authenticity to, or upon the order of, NewMarket Corporation and (ii) present such initial notes for transfer on the books of NewMarket Corporation and receive all benefits and otherwise exercise all rights of beneficial ownership of such initial notes, all in accordance with the terms of the Exchange Offer. The power of attorney granted in this paragraph shall be deemed irrevocable and coupled with an interest.

The undersigned hereby represents and warrants that he or she has full power and authority to tender, exchange, sell, assign and transfer the initial notes tendered hereby and to acquire the exchange notes issuable upon the exchange of the initial notes, and that NewMarket Corporation will acquire good and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim, when the same are acquired by NewMarket Corporation. The undersigned also acknowledges that this Exchange Offer is being made in reliance upon an interpretation by the staff of the Securities and Exchange Commission, as set forth in no-action letters to third parties, that the exchange notes issued in exchange for the initial notes pursuant to the Exchange Offer may be offered for sale, resold and otherwise transferred by holders thereof (other than a broker-dealer who purchased such initial notes directly from NewMarket Corporation for resale pursuant to Rule 144A or any other available exemption under the Securities Act or a holder that is an “affiliate” of NewMarket Corporation as defined in Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act,provided that such exchange notes are acquired by a non-affiliate in the ordinary course of such holder’s business and such holders have no arrangement or understanding with any person to participate in the distribution of such exchange notes.

The undersigned hereby represents and warrants that:

(a)

the undersigned is acquiring the exchange notes pursuant to this Exchange Offer in the ordinary course of business;

(b)

the undersigned has no arrangements or understanding with any person to participate in the distribution of the initial notes or the exchange notes within the meaning of the Securities Act;

(c)

the undersigned is not an “affiliate,” as defined in Rule 405 of the Securities Act, of NewMarket Corporation, or if the undersigned is an affiliate of NewMarket Corporation, the undersigned will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable;

(d)

if the undersigned is not a broker-dealer, the undersigned is not engaged in, and does not intend to engage in, the distribution of the exchange notes; and

(e)

if the undersigned is a broker-dealer, the undersigned is receiving the exchange notes for the undersigned’s own account in exchange for the initial notes that the undersigned acquired as a result of market-making activities or other trading activities, and the undersigned acknowledges that the undersigned will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of the exchange notes.

By acknowledging that the undersigned, as such a broker-dealer, will deliver and by delivering a prospectus meeting the requirements of the Securities Act in connection with any resale of exchange notes, the undersigned will not be deemed to admit that the undersigned is an “underwriter” within the meaning of the Securities Act.

The undersigned will, upon request, execute and deliver any additional documents deemed by the exchange agent or NewMarket Corporation to be necessary or desirable to complete the exchange, assignment and transfer of the initial notes tendered hereby or transfer of ownership of such initial notes on the account books maintained by a book-entry transfer facility.

The Exchange Offer is subject to certain conditions set forth in the Prospectus under the caption “The Exchange Offer—Conditions to the Exchange Offer.” The undersigned recognizes that as a result of these conditions, as more particularly set forth in the prospectus, the Company may not be required to exchange any of the initial tendered hereby and, in such event, the initial notes not exchanged will be returned to the undersigned at the address shown below the signature of the undersigned.

For purposes of the Exchange Offer, NewMarket Corporation shall be deemed to have accepted validly tendered initial notes when, as and if NewMarket Corporation has given oral or written notice thereof to the exchange agent. If any tendered initial notes are not accepted for exchange pursuant to the Exchange Offer for any reason, such unaccepted or non-exchanged initial notes will be returned to the address shown below or to a different address as may be indicated herein under “Special Delivery Instructions,” without expense to the tendering Holder thereof, (or, in the case of tender by book-entry transfer into the exchange agent’s account at the book-entry transfer pursuant to the book-entry transfer procedures described in the prospectus under the “The Exchange Offer—Procedures for Tendering—Book-Entry Transfer,” such non-exchanged notes will be credited to an account maintained with such book-entry transfer facility) promptly after the expiration or termination of the Exchange Offer.

The undersigned understands and acknowledges that NewMarket Corporation reserves the right in its sole discretion to purchase or make offers for any initial notes that remain outstanding subsequent to the Expiration Date or, as set forth in the prospectus under the caption “The Exchange Offer—Expiration Date; Extensions; Amendment; Termination,” to terminate the Exchange Offer and, to the extent permitted by applicable law, purchase initial notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers could differ from the terms of the Exchange Offer.

The undersigned understands that tenders of initial notes pursuant to the procedures described under the caption “The Exchange Offer —Procedures for Tendering” in the prospectus and in the instructions hereto will constitute a binding agreement between the undersigned and NewMarket Corporation upon the terms and subject to the conditions of the Exchange Offer. The undersigned also agrees that acceptance of any tendered initial notes by NewMarket Corporation and the issuance of exchange notes in exchange therefor shall constitute performance in full by NewMarket Corporation of their respective obligations under the Exchange Offer and Registration Rights Agreement and that, upon the issuance of the exchange notes, NewMarket Corporation will have no further obligations or liabilities thereunder (except in certain limited circumstances).

All authority conferred or agreed to be conferred by this letter of transmittal shall survive the death, incapacity or dissolution of the undersigned and every obligation under this letter of transmittal shall be binding upon the undersigned’s heirs, personal representatives, successors and assigns. This tender may be withdrawn only in accordance with the procedures set forth in the prospectus and in this letter of transmittal.

By acceptance of the Exchange Offer, each broker-dealer that receives exchange notes pursuant to the Exchange Offer hereby acknowledges and agrees that, upon the receipt of notice by NewMarket Corporation of the happening of any event that makes any statement in the prospectus untrue in any material respect or that requires the making of any changes in the prospectus in order to make the statements therein not misleading (which notice NewMarket Corporation agrees to deliver promptly to such broker-dealer), such broker-dealer will suspend use of the prospectus until NewMarket Corporation has amended or supplemented the prospectus to correct such misstatement or omission and has furnished copies of the amended or supplemented prospectus to such broker-dealer.

Unless otherwise indicated under “Special Registration Instructions,” please issue the certificates representing the exchange notes issued in exchange for the initial notes accepted for exchange and return any initial notes not tendered or not exchanged, in the name(s) of the undersigned (or in either such event in the case of initial notes tendered by DTC, by credit to the respective account at DTC). Similarly, unless otherwise indicated under “Special Delivery Instructions,” please send the certificates representing the exchange notes issued in exchange for the initial notes accepted for exchange and return any initial notes not tendered or not exchanged (and accompanying documents, as appropriate) to the undersigned at the address shown below the undersigned’s signatures, unless, in either event, tender is being made through DTC. In the event that both “Special Registration Instructions” and “Special Delivery Instructions” are completed, please issue the certificates representing the exchange notes issued in exchange for the initial notes accepted for exchange and return any initial notes not tendered or not exchanged in the name(s) of, and send said certificates to, the person(s) so indicated. The undersigned recognizes that NewMarket Corporation has no obligations pursuant to the “Special Registration Instructions” and “Special Delivery Instructions” to transfer any initial notes from the name of the registered holder(s) thereof if NewMarket Corporation does not accept for exchange any of the initial notes so tendered.

Holders who wish to tender the initial notes and (1) whose initial notes are not immediately available or (2) who cannot deliver their initial notes, this letter of transmittal or any other documents required hereby to the exchange agent prior to the Expiration Date may tender their initial notes according to the guaranteed delivery procedures set forth in the prospectus under the caption “The Exchange Offer—Procedures for Tendering—Guaranteed Delivery Procedures.” (See Instruction 2.)

INSTRUCTIONS

Forming part of the terms and conditions

of the Exchange Offer

1.Guarantee of Signatures. Signatures on this letter of transmittal (or copy hereof) or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of a registered national securities exchange or of the Financial Industry Regulatory Authority, Inc., a commercial bank or trust company having an office or correspondent in the United States or an “eligible guarantor institution” within the meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934 (an “Eligible Institution”) unless the initial notes tendered pursuant thereto are tendered (i) by a registered Holder (including any participant in DTC whose name appears on a security position listing as the owner of initial notes) who has not completed the box set forth herein entitled “Special Registration Instructions” or “Special Delivery Instructions” of this letter of transmittal or (ii) for the account of an Eligible Institution.

2.Delivery of this Letter of Transmittal and Initial Notes. Certificates for the physically tendered initial notes (or a confirmation of a book-entry transfer to the exchange agent at DTC of all initial notes tendered electronically), as well as, in the case of physical delivery of initial notes, a properly completed and duly executed copy of this letter of transmittal or facsimile hereof and any other documents required by this letter of transmittal must be received by the exchange agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. The method of delivery of the tendered initial notes, this letter of transmittal and all other required documents, or book-entry transfer and transmission of an Agent’s Message (as defined below) by a DTC participant, to the exchange agent are at the election and risk of the Holder and, except as otherwise provided below, the delivery will be deemed made only when actually received by the exchange agent. Instead of delivery by mail, it is recommended that the Holder use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery. No letter of transmittal or initial notes should be sent to NewMarket Corporation or DTC.

The exchange agent will make a request to establish an account with respect to the initial notes at DTC for purposes of the Exchange Offer promptly after receipt of the prospectus, and any financial institution that is a participant in DTC may make book-entry delivery of initial notes by causing DTC to transfer such initial notes into the exchange agent’s account at DTC in accordance with the relevant entity’s procedures for transfer. However, although delivery of initial notes may be effected through book-entry transfer at DTC, an Agent’s Message in connection with a book-entry transfer and any other required documents must, in any case, be transmitted to and received by the exchange agent at the address specified on the cover page of the letter of transmittal on or prior to the Expiration Date or the guaranteed delivery procedures described below must be complied with.

A Holder may tender initial notes that are held through DTC by transmitting its acceptance through DTC’s Automatic Tender Offer Program, for which the transaction will be eligible, and DTC will then edit and verify the acceptance and send an Agent’s Message to the exchange agent for its acceptance. The term “Agent’s Message” means a message transmitted by DTC to, and received by, the exchange agent and forming part of the Book-Entry Confirmation, which states that DTC has received an express acknowledgment from each participant in DTC tendering the initial notes and that such participant has received the letter of transmittal and agrees to be bound by the terms of the letter of transmittal and NewMarket Corporation may enforce such agreement against such participant. Delivery of an Agent’s Message will also constitute an acknowledgment from the tendering DTC participant that the representations and warranties set forth on pages 4 and 5 of this letter of transmittal are true and correct.

Holders who wish to tender their initial notes and (i) whose initial notes are not immediately available or (ii) who cannot deliver their initial notes, this letter of transmittal or any other documents required hereby to the exchange agent prior to the Expiration Date, or who cannot complete the procedure for book-entry transfer on a timely basis must tender their initial notes and follow the guaranteed delivery procedures set forth in the prospectus. Pursuant to such procedures: (i) such tender must be made by or through an Eligible Institution (as defined above) or pursuant to the DTC standard operating procedures; (ii) prior to the Expiration Date, the exchange agent must have received from the Eligible Institution a properly completed and duly executed notice of guaranteed delivery (by facsimile transmission, mail or hand delivery) setting forth the name and address of the Holder of the initial notes, the certificate number or numbers of such initial notes and the principal amount of initial notes tendered, stating that the tender is being made thereby and guaranteeing that within three (3) business days after the Expiration Date, this letter of transmittal (or copy thereof) together with the certificate(s) representing the initial notes (or a confirmation of electronic delivery or book-entry delivery into the exchange agent’s

account at DTC) and any of the required documents will be deposited by the Eligible Institution with the exchange agent and (iii) such properly completed and executed letter of transmittal (or copy thereof), as well as all other documents required by this letter of transmittal and the certificate(s) representing all tendered initial notes in proper form for transfer or a confirmation of electronic delivery or book-entry delivery into the exchange agent’s account at DTC, must be received by the exchange agent within three (3) business days after the Expiration Date, all as provided in the prospectus under the caption “The Exchange Offer—Procedures for Tendering—Guaranteed Delivery Procedures.” Any Holder of initial notes who wishes to tender his initial notes pursuant to the guaranteed delivery procedures described above must ensure that the exchange agent receives the notice of guaranteed delivery prior to 5:00 p.m., New York City time, on the Expiration Date. Upon request to the exchange agent, a notice of guaranteed delivery will be sent to Holders who wish to tender their initial notes according to the guaranteed delivery procedures set forth above.

All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of tendered initial notes or this letter of transmittal will be determined by NewMarket Corporation in its sole discretion, which determination will be final and binding. All tendering Holders, by execution of this letter of transmittal (or copy hereof), shall waive any right to receive notice of the acceptance of the initial notes for exchange. NewMarket Corporation reserves the absolute right to reject any and all initial notes or letters of transmittal not properly tendered or any tenders NewMarket Corporation’s acceptance of which would, in the opinion of counsel for NewMarket Corporation, be unlawful. NewMarket Corporation also reserves the absolute right to waive any defects, irregularities or conditions of tender as to particular initial notes. NewMarket Corporation’s interpretation of the terms and conditions of the Exchange Offer (including the instructions in this letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of initial notes must be cured within such time as NewMarket Corporation shall determine. Although NewMarket Corporation intends to notify Holders of defects or irregularities with respect to tenders of initial notes, none of NewMarket Corporation, the exchange agent or any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of initial notes, nor shall any of them incur any liability for failure to give such notification. Tenders of initial notes will not be deemed to have been made until such defects or irregularities have been cured or waived. Any initial notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the exchange agent to the tendering Holders of initial notes, unless otherwise provided in this letter of transmittal, as soon as practicable following the Expiration Date.

3.Inadequate Space. If the space provided is inadequate, the certificate numbers and/or the number of the initial notes should be listed on a separate signed schedule attached hereto.

4.Tender by Holder. Except in limited circumstances, only a registered Holder of initial notes or a DTC participant listed on a securities position listing furnished by DTC with respect to the initial notes may tender its initial notes in the Exchange Offer. Any beneficial owner of initial notes who is not the registered Holder and is not a DTC participant and who wishes to tender should arrange with such registered holder to execute and deliver this letter of transmittal on such beneficial owner’s behalf or must, prior to completing and executing this letter of transmittal and delivering his, her or its initial notes, either make appropriate arrangements to register ownership of the initial notes in such beneficial owner’s name or obtain a properly completed bond power from the registered holder or properly endorsed certificates representing such initial notes.

5.Partial Tenders; Withdrawals. Tenders of initial notes will be accepted only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. If less than the entire principal amount of any initial notes is tendered, the tendering Holder should fill in the principal amount tendered in the fourth column of the chart entitled “Description of Initial Notes.” The entire principal amount of initial notes delivered to the exchange agent will be deemed to have been tendered unless otherwise indicated. If the entire principal amount of all initial notes is not tendered, initial notes for the principal amount of initial notes not tendered and a certificate or certificates representing exchange notes issued in exchange of any initial notes accepted will be sent to the Holder at his or her registered address, unless a different address is provided in the appropriate box on this letter of transmittal or unless tender is made through DTC, promptly after the initial notes are accepted for exchange.

Except as otherwise provided herein, tenders of initial notes may be withdrawn at any time prior to the Expiration Date. To withdraw a tender of initial notes in the Exchange Offer, a written or facsimile transmission notice of withdrawal must be received by the exchange agent at its address set forth herein prior to the Expiration Date. Any such notice of withdrawal must (1) specify the name of the person having deposited the initial notes to be withdrawn (the “Depositor”), (2) identify the initial notes to be withdrawn (including the certificate number or numbers and principal amount of such

initial notes, or, in the case of initial notes transferred by book-entry transfer, the name and number of the account at DTC to be credited), (3) be signed by the Depositor in the same manner as the original signature on the letter of transmittal by which such initial notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the registrar with respect to the initial notes register the transfer of such initial notes into the name of the person withdrawing the tender and (4) specify the name in which any such initial notes are to be registered, if different from that of the Depositor. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by NewMarket Corporation, whose determination shall be final and binding on all parties. Any initial notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no exchange notes will be issued with respect thereto unless the initial notes so withdrawn are validly re -tendered. Any initial notes which have been tendered but which are not accepted for exchange by NewMarket Corporation will be returned to the Holder thereof without cost to such Holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn initial notes may be re -tendered by following one of the procedures described in the prospectus under “The Exchange Offer—Procedures for Tendering” at any time prior to the Expiration Date.

6.Signatures on the Letter of Transmittal; Bond Powers and Endorsements. If this letter of transmittal (or a copy hereof) is signed by the registered Holder(s) of the initial notes tendered hereby, the signature must correspond with the name(s) as written on the face of the initial notes without alteration, enlargement or any change whatsoever.

If any of the initial notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this letter of transmittal.

If a number of initial notes registered in different names are tendered, it will be necessary to complete, sign and submit as many copies of this letter of transmittal as there are different registrations of initial notes.

If this letter of transmittal (or a copy hereof) is signed by the registered Holder(s) (which term, for the purposes described herein, shall include a book-entry transfer facility whose name appears on the security listing as the owner of the initial notes) of initial notes tendered and the certificate(s) for exchange notes issued in exchange therefor is to be issued (or any untendered principal amount of initial notes is to be reissued) to the registered Holder, such Holder need not and should not endorse any tendered initial note, nor provide a separate bond power. In any other case, such Holder must either properly endorse the initial notes tendered or transmit a properly completed separate bond power with this letter of transmittal, with the signatures on the endorsement or bond power guaranteed by an Eligible Institution.

If this letter of transmittal (or a copy hereof) is signed by a person other than the registered Holder(s) of initial notes listed therein, such initial notes must be endorsed or accompanied by properly completed bond powers which authorize such person to tender the initial notes on behalf of the registered Holder, in either case signed as the name of the registered Holder or Holders appears on the initial notes.

If this letter of transmittal (or a copy hereof) or any initial notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in -fact, or officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and, unless waived by NewMarket Corporation, evidence satisfactory to NewMarket Corporation of their authority to so act must be submitted with this letter of transmittal.

Endorsements on initial notes or signatures on bond powers required by this Instruction 6 must be guaranteed by an Eligible Institution.

7.Special Registration and Delivery Instructions. Tendering Holders should indicate, in the applicable spaces, the name and address to which exchange notes or substitute initial notes for principal amounts not tendered or not accepted for exchange are to be issued or sent, if different from the name and address of the person signing this letter of transmittal (or in the case of tender of the initial notes through DTC, if different from the account maintained at DTC indicated above). In the case of issuance in a different name, the taxpayer identification or social security number of the person named must also be indicated.

8.Transfer Taxes. NewMarket Corporation will pay all transfer taxes, if any, applicable to the exchange of initial notes pursuant to the Exchange Offer. If, however, certificates representing exchange notes or initial notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be registered or issued in the name of, any person other than the registered Holder of the initial notes tendered hereby, or if tendered initial notes are registered in the name

of any person other than the person signing this letter of transmittal, or if a transfer tax is imposed for any reason other than the exchange of initial notes pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered Holder or any other person) will be payable by the tendering Holder.

IMPORTANT TAX INFORMATION

A tendering Holder of the initial notes is required to give the exchange agent such Holder’s social security number or employer identification number (“TIN”) or establish a basis for exemption from backup withholding. If the initial notes are in more than one name or are not 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.

Certain tendering Holders (including, among others, all corporations and certain foreign persons) are not subject to these backup withholding and reporting requirements. Exempt Holders should indicate their exempt status on Substitute Form W-9. A foreign person may qualify as an exempt recipient by submitting to the exchange agent a properly completed Internal Revenue Service Form W-8BEN, signed under penalties of perjury, attesting to that Holder’s exempt status. A Form W-8BEN can be obtained from the exchange agent. See the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional instructions.

A Holder shall write “applied for” in the box in Part 1 of the form if the tendering Holder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If “applied for” is written in the box in Part 1 and the exchange agent is not provided with a TIN within 60 days thereafter, the exchange agent will withhold 28% on all payments under the notes until a TIN is provided to the exchange agent.

Guidelines for Determining the Proper Identification Number to Give the Payer. Social security numbers and individual taxpayer identification numbers have nine digits separated by two hyphens: i.e. 000-00-0000. If you are a resident alien and you do not have and are not eligible to get a social security number, your taxpayer identification number is your IRS individual taxpayer identification number (ITIN). Employer identification numbers have nine digits separated by only one hyphen: i.e. 00-0000000. The table below will help determine the number to give the payer.

Privacy Act Notice. Section 6109 requires most recipients of dividend, interest, or other payments to give taxpayer identification numbers to payers who must report the payments to the IRS. The IRS uses the numbers for identification purposes. 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) Penalty for 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 which results in no imposition of backup withholding, you are subject to a penalty of $500.

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