Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to OGIL the above-described aggregate principal amount of Old Notes in exchange for a like aggregate principal amount of Exchange Notes which have been registered under the Securities Act of 1933, as amended (the “Securities Act”), upon the terms and subject to the conditions set forth in the Prospectus, receipt of which is acknowledged, and in this Letter of Transmittal.

Subject to and effective upon the acceptance for exchange of all or any portion of the Old Notes tendered herewith in accordance with the terms and conditions of the Exchange Offer (including, if the Exchange Offer is extended or amended, the terms and conditions of any such extension or amendment), the undersigned hereby sells, assigns and transfers to or upon the order of OGIL all right, title and interest in and to such Old Notes as is being tendered herewith. The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as its agent and attorney-in-fact (with full knowledge that the Exchange Agent is also acting as agent of OGIL in connection with the Exchange Offer) with respect to the tendered Old Notes, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest) subject only to the right of withdrawal described in the Prospectus, to (i) deliver Certificates for Old Notes to OGIL together with all accompanying evidences of transfer and authenticity to, or upon the order of, OGIL, upon receipt by the Exchange Agent, as the undersigned’s agent, of the Exchange Notes to be issued in exchange for such Old Notes, (ii) present Certificates for such Old Notes for transfer, and to transfer the Old Notes on the books of OGIL, and (iii) receive for the account of OGIL all benefits and otherwise exercise all rights of beneficial ownership of such Old Notes, all in accordance with the terms and conditions of the Exchange Offer.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, exchange, sell, assign and transfer the Old Notes tendered hereby and that, when the same is accepted for exchange, OGIL will acquire good, marketable and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances, and that the Old Notes tendered hereby are not subject to any adverse claims or proxies. The undersigned will, upon request, execute and deliver any additional documents deemed by OGIL or the Exchange Agent to be necessary or desirable to complete the exchange, assignment and transfer of the Old Notes tendered hereby, and the undersigned will comply with its obligations under the registration rights agreement.

The name(s) and address(es) of the registered holder(s) of the Old Notes tendered hereby should be printed above, if they are not already set forth above, as they appear on the Certificates representing such Old Notes. The Certificate number(s) and the Old Notes that the undersigned wishes to tender should be indicated in the appropriate boxes above.

If any tendered Old Notes are not exchanged pursuant to the Exchange Offer for any reason, or if Certificates are submitted for more Old Notes than are tendered or accepted for exchange, Certificates for such nonexchanged or nontendered Old Notes will be returned (or, in the case of Old Notes tendered by book-entry transfer, such Old Notes will be credited to an account maintained at DTC), without expense to the tendering holder, promptly following the expiration or termination of the Exchange Offer.

Tenders of Old Notes pursuant to any one of the procedures described in “The Exchange Offer–Procedures for Tendering” in the Prospectus and in the instructions attached hereto will, upon OGIL’s acceptance for exchange of such tendered Old Notes, constitute a binding agreement between the undersigned and OGIL upon the terms and subject to the conditions of the Exchange Offer. Under certain circumstances set forth in the Prospectus, OGIL may not be required to accept for exchange any of the Old Notes tendered hereby.

Unless otherwise indicated herein in the box entitled “Special Issuance Instructions” below, the undersigned hereby directs that the Exchange Notes be issued in the name(s) of the undersigned or, in the case of a book-entry transfer of Old Notes, that such Exchange Notes be credited to the account indicated above maintained at DTC. If applicable, substitute Certificates representing Old Notes not exchanged or not accepted for exchange will be issued to the undersigned or, in the case of a book-entry transfer of Old Notes, will be credited to the account indicated above maintained at DTC. Similarly, unless otherwise indicated under “Special Delivery Instructions,” please deliver Exchange Notes to the undersigned at the address shown below the undersigned’s signature.

By tendering Old Notes and executing this Letter of Transmittal, the undersigned hereby represents and agrees that: (i) the undersigned is not an “affiliate” of OGIL, or if it is such an affiliate, that the Exchange Notes may not be offered for resale, resold or otherwise transferred without registration under and in compliance with the Prospectus delivery requirement of the Securities Act or an exemption therefrom, (ii) any Exchange Notes to be received by the undersigned are being acquired in the ordinary course of its business, (iii) the undersigned has no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of Exchange Notes to be received in the Exchange Offer, (iv) if the undersigned is not a broker-dealer, the undersigned is not engaged in, and does not intend to engage in, a distribution (within the meaning of the Securities Act) of such Exchange Notes, (v) the undersigned has full power and authority to transfer the Old Notes in exchange for the Exchange Notes and that OGIL will acquire good and unencumbered title thereto free and clear of any liens, restrictions, charges or encumbrances and not subject to any adverse claims, and

(vi) the undersigned is not acting on behalf of any person or entity that could not truthfully make the above representations. By tendering Old Notes pursuant to the Exchange Offer and executing this Letter of Transmittal, a holder of Old Notes that is a broker-dealer represents, and agrees, consistent with certain interpretative letters issued by the staff of the Division of Corporate Finance of the Securities and Exchange Commission to third parties, that (A) such Old Notes held by the broker-dealer are held only as a nominee, or (B) such Old Notes were acquired by such broker-dealer for its own account as a result of market-making activities or other trading activities and it will deliver the Prospectus (as amended or supplemented from time to time) meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes (provided that, by so acknowledging and by delivering a Prospectus, such broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act).

OGIL has agreed that, subject to the provisions of the registration rights agreement executed in connection with issuance of the Old Notes, the Prospectus, as it may be amended or supplemented from time to time, may be used by a Participating Broker-Dealer (as defined below) in connection with resales of Exchange Notes received in exchange for Old Notes, where such Old Notes were acquired by such Participating Broker-Dealer for its own account as a result of market-making activities or other trading activities, for a period ending on the earlier of (i) 120 days after the Exchange Offer registration statement is declared effective or (ii) the date on which a broker-dealer is no longer required to deliver a Prospectus in connection with market-making or other trading activities. In that regard, each broker-dealer who acquired Old Notes for its own account as a result of market-making or other trading activities (a “Participating Broker-Dealer”), by tendering such Old Notes and executing this Letter of Transmittal, agrees that, upon receipt of notice from OGIL of the occurrence of any event or the discovery of any fact which makes any statement contained or incorporated by reference in the Prospectus untrue in any material respect or which causes the Prospectus to omit to state a material fact necessary to make the statements contained or incorporated by reference therein, in light of the circumstances under which they were made, not misleading or of the occurrence of certain other events specified in the registration rights agreement, such Participating Broker-Dealer will suspend the sale of Exchange Notes pursuant to the Prospectus until OGIL has amended or supplemented the Prospectus to correct such misstatement or omission and has furnished copies of the amended or supplemented Prospectus to the Participating Broker-Dealer or OGIL has given notice that the sale of Exchange Notes may be resumed, as the case may be.

Holders of Old Notes whose Old Notes are accepted for exchange will not receive accrued interest on such Old Notes for any period from and after the last Interest Payment Date to which interest has been paid or duly provided for on such Old Notes prior to the original issue date of the Exchange Notes or, if no such interest has been paid or duly provided for, will not receive any accrued interest on such Old Notes, and the undersigned waives the right to receive any such interest on such Old Notes accrued from and after such Interest Payment Date or, if no such interest has been paid or duly provided for, from and after February 1, 2012. The Exchange Notes will bear interest from the most recent Interest Payment Date to which interest has been paid on the Old Notes or, if no interest has been paid, from February 1, 2012.

The undersigned will, upon request, execute and deliver any additional documents deemed by OGIL to be necessary or desirable to complete the sale, assignment and transfer of the Old Notes tendered hereby. All authority herein conferred or agreed to be conferred in this Letter of Transmittal shall survive the death or incapacity of the undersigned and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, legal representatives, successors and assigns of the undersigned. Except as stated in the Prospectus, this tender is irrevocable.

The undersigned, by completing the box entitled “Description of Old Notes” above and signing this letter, will be deemed to have tendered the Old Notes as set forth in such box.

1. Delivery of Letter of Transmittal and Certificates; Guaranteed Delivery Procedures. This Letter of Transmittal is to be completed either if (a) Certificates are to be forwarded herewith or (b) tenders are to be made pursuant to the procedures for tender by book-entry transfer set forth in “The Exchange Offer” in the Prospectus and an agent’s message is not delivered. Certificates, or timely confirmation of a book-entry transfer of such Old Notes into the Exchange Agent’s account at DTC, as well as this Letter of Transmittal (or facsimile thereof), properly completed and duly executed, with any required signature guarantees, and any other documents required by this Letter of Transmittal must be received by the Exchange Agent at its address set forth herein on or prior to the Expiration Date. Tenders by book-entry transfer may also be made by delivering an agent’s message in lieu thereof. Old Notes may be tendered in whole or in part in denominations of principal amount of $2,000 and any integral multiple of $1,000.

Holders who wish to tender their Old Notes and (i) whose Old Notes are not immediately available or (ii) who cannot deliver their Old Notes, this Letter of Transmittal and all other required documents to the Exchange Agent on or prior to the Expiration Date or (iii) who cannot complete the procedures for delivery by book-entry transfer on a timely basis, may tender their Old Notes by properly completing and duly executing a Notice of Guaranteed Delivery pursuant to the guaranteed delivery procedures set forth in “The Exchange Offer” in the Prospectus. Pursuant to such procedures: (i) such tender must be made by or through an Eligible Institution (as defined below); (ii) a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form made available by OGIL, must be received by the Exchange Agent on or prior to the Expiration Date; and (iii) the Certificates (or a book-entry confirmation) representing all tendered Old Notes, in proper form for transfer, together with a Letter of Transmittal (or facsimile thereof), properly completed and duly executed, with any required signature guarantees and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent within three New York Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery, all as provided in “The Exchange Offer” in the Prospectus.

The Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile or mail to the Exchange Agent, and must include a guarantee by an Eligible Institution in the form set forth in such Notice of Guaranteed Delivery. For Old Notes to be properly tendered pursuant to the guaranteed delivery procedure, the Exchange Agent must receive a Notice of Guaranteed Delivery on or prior to the Expiration Date. As used herein and in the Prospectus, “Eligible Institution” means a firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an “eligible guarantor institution,” including (as such terms are defined therein): (i) a bank; (ii) a broker, dealer, municipal securities broker or dealer or government securities broker or dealer; (iii) a credit union; (iv) a national securities exchange, registered securities association or clearing agency; or (v) a savings association that is a participant in a Securities Transfer Association.

The method of delivery of Certificates, this Letter of Transmittal and all other required documents is at the option and sole risk of the tendering holder, and the delivery will be deemed made only when actually received by the Exchange Agent. If delivery is by mail, then registered mail with return receipt requested, properly insured, or overnight delivery service is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

OGIL will not accept any alternative, conditional or contingent tenders. Each tendering holder, by execution of a Letter of Transmittal (or facsimile thereof), waives any right to receive any notice of the acceptance of such tender.

2. Guarantee of Signatures. No signature guarantee on this Letter of Transmittal is required if:

In all other cases, an Eligible Institution must guarantee the signature(s) on this Letter of Transmittal. See Instruction 5.

3. Inadequate Space. If the space provided in the box captioned “Description of Old Notes” is inadequate, the Certificate number(s) and or the principal amount of Old Notes and any other required information should be listed on a separate signed schedule that is attached to this Letter of Transmittal.

4. Partial Tenders and Withdrawal Rights. Tenders of Old Notes will be accepted only in denominations of principal amount of $2,000 and any integral multiple of $1,000. If less than all the Old Notes evidenced by any Certificate submitted are to be tendered, fill in the principal amount of Old Notes that are to be tendered in the box entitled “Principal Amount of Old Notes Tendered.” In such case, new Certificate(s) for the remainder of the Old Notes that were evidenced by your old Certificate(s) will only be sent to the holder of the Old Notes, promptly after the Expiration Date. All Old Notes represented by Certificates delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated.

Except as otherwise provided herein, tenders of Old Notes may be withdrawn at any time on or prior to the Expiration Date. In order for a withdrawal to be effective on or prior to that time, a written or facsimile transmission of such notice of withdrawal must be timely received by the Exchange Agent at one of its addresses set forth above or in the Prospectus on or prior to the Expiration Date. Any such notice of withdrawal must specify the name of the person who tendered the Old Notes to be withdrawn, the aggregate principal amount of Old Notes to be withdrawn, and (if Certificates have been tendered) the name of the registered holder of the Old Notes as set forth on the Certificate, if different from that of the person who tendered such Old Notes. If Certificates have been delivered or otherwise identified to the Exchange Agent, then prior to the physical release of such Certificates, the tendering holder must submit the serial numbers shown on the particular Certificates to be withdrawn and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution, except in the case of Old Notes tendered for the account of an Eligible Institution. If Old Notes have been tendered pursuant to the procedures for book-entry transfer set forth in the Prospectus under “The Exchange Offer,” the notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawal of Old Notes, in which case a notice of withdrawal will be effective if delivered to the Exchange Agent by written, telegraphic, telex or facsimile transmission. Withdrawals of tenders of Old Notes may not be rescinded. Old Notes properly withdrawn will not be deemed validly tendered for purposes of the Exchange Offer, but may be retendered at any subsequent time on or prior to the Expiration Date by following any of the procedures described in the Prospectus under “The Exchange Offer.”

All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices will be determined by OGIL, in its sole discretion, whose determination shall be final and binding on all parties. OGIL, any affiliates or assigns of OGIL, the Exchange Agent or any other person shall not be under any duty to give any notification of any irregularities in any notice of withdrawal or incur any liability for failure to give any such notification. Any Old Notes that have been tendered but that are withdrawn will be returned to the holder thereof without cost to such holder promptly after withdrawal.

5. Signatures on Letter of Transmittal, Assignments and Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the Old Notes tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the Certificate(s) without alteration, enlargement or any change whatsoever.

If any Old Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal.

If any tendered Old Notes are registered in different name(s) on several Certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles thereof) as there are different registrations of Certificates.

If this Letter of Transmittal or any Certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and, unless waived by OGIL, must submit proper evidence satisfactory to OGIL, in its sole discretion, of each such person’s authority to so act.

When this Letter of Transmittal is signed by the registered owner(s) of the Old Notes listed and transmitted hereby, no endorsement(s) of Certificate(s) or separate bond power(s) is required unless Exchange Notes are to be issued in the name of a person other than the registered holder(s). Signature(s) on such Certificate(s) or bond power(s) must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered owner(s) of the Old Notes listed, the Certificates must be endorsed or accompanied by appropriate bond powers, signed exactly as the name or names of the registered owner(s) appear(s) on the Certificates, and also must be accompanied by such opinions of counsel, certifications and other information as OGIL or the Trustee for the Old Notes may require in accordance with the restrictions on transfer applicable to the Old Notes. Signatures on such Certificates or bond powers must be guaranteed by an Eligible Institution.

6. Special Issuance and Delivery Instructions. If Exchange Notes are to be issued in the name of a person other than the signer of this Letter of Transmittal, or if Exchange Notes are to be sent to someone other than the signer of this Letter of Transmittal or to an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed. Certificates not exchanged will be returned by mail or, if tendered by book-entry transfer, by crediting the account indicated above maintained at DTC. See Instruction 4.

7. Irregularities. OGIL will determine, in its sole discretion, all questions as to the form of documents, validity, eligibility (including time of receipt) and acceptance for exchange of any tender of Old Notes, which determination shall be final and binding on all parties. OGIL reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance of which, or exchange for which may, in the view of counsel to OGIL be unlawful. OGIL also reserves the absolute right, subject to applicable law, to waive any of the conditions of the Exchange Offer set forth in the Prospectus under “The Exchange Offer” or any conditions or irregularities in any tender of Old Notes of any particular holder whether or not similar conditions or irregularities are waived in the case of other holders. OGIL’s interpretation of the terms and conditions of the Exchange Offer (including this Letter of Transmittal and the instructions hereto) will be final and binding. No tender of Old Notes will be deemed to have been validly made until all irregularities with respect to such tender have been cured or waived. OGIL, any affiliates or assigns of OGIL, the Exchange Agent, or any other person shall not be under any duty to give notification of any irregularities in tenders or incur any liability for failure to give such notification.

8. Questions, Requests for Assistance and Additional Copies. Questions and requests for assistance may be directed to the Exchange Agent at its address and telephone number set forth on the front of this Letter of Transmittal. Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the Letter of Transmittal may be obtained from the Exchange Agent or from your broker, dealer, commercial bank, trust company or other nominee.

9. Backup Withholding; Substitute Form W-9. Under U.S. federal income tax law, a holder (including, for purposes of this section, beneficial owners of the Old Notes) whose tendered Old Notes are accepted for exchange is required to provide the Exchange Agent with such holder’s correct taxpayer identification number (“TIN”) on Substitute Form W-9 below. If the Exchange Agent is not provided with the correct TIN, the Internal Revenue Service (the “IRS”) may subject the holder or other payee to a $50 penalty. In addition, payments to such holders or other payees with respect to Old Notes exchanged pursuant to the Exchange Offer may be subject to backup withholding at a rate equal to 28%.

The box in Part 2 of the Substitute Form W-9 may be checked 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 the box in Part 2 is checked, the holder or other payee must also complete the box captioned Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that the box in Part 2 is checked and the box captioned Certificate of Awaiting Taxpayer Identification Number is completed, the holder will be subject to backup withholding on all payments made prior to the time a properly certified TIN is provided to the Exchange Agent. The Exchange Agent will retain such amounts withheld during the 60-day period following the date of the Substitute Form W-9. If the holder furnishes the Exchange Agent with its TIN within 60 days after the date of the Substitute Form W-9, the amounts retained during the 60-day period will be remitted to the holder and no further amounts shall be retained or withheld from payments made to the holder thereafter. If, however, the holder has not provided the Exchange Agent with its TIN within such 60-day period, amounts withheld will be remitted to the IRS as backup withholding. In addition, backup withholding will apply to all payments made thereafter until a correct TIN is provided.

Certain holders (including, among others, corporations, financial institutions and certain foreign persons) may not be subject to the backup withholding and reporting requirements. Such holders should nevertheless complete the attached Substitute Form W-9 and write “Exempt” on the face thereof, to avoid possible erroneous backup withholding. A foreign person may qualify as an exempt recipient by submitting a properly completed and appropriate IRS Form W-8, signed under penalties of perjury, attesting to that holder’s exempt status. Please consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidance on which holders are exempt from backup withholding.

Backup withholding is not an additional U.S. federal income tax. Rather, the U.S. federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is furnished to the IRS.

10. Waiver of Conditions. OGIL reserves the absolute right to waive satisfaction of any or all conditions enumerated in the Prospectus.

11. No Conditional Tenders. No alternative, conditional or contingent tenders will be accepted. All tendering holders of Old Notes, by execution of this Letter of Transmittal, shall waive any right to receive notice of the acceptance of Old Notes for exchange.

Neither OGIL, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of Old Notes nor shall any of them incur any liability for failure to give any such notice.

12. Lost, Destroyed or Stolen Certificates. If any Certificate(s) representing Old Notes have been lost, destroyed or stolen, the holder should promptly notify the Exchange Agent. The holder will then be instructed as to the steps that must be taken in order to replace the Certificate(s). This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed or stolen Certificate(s) have been followed.

13. Security Transfer Taxes. Holders who tender their Old Notes for exchange will not be obligated to pay any transfer taxes in connection therewith. If, however, Exchange Notes are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the Old Notes tendered, or if a transfer tax is imposed for any reason other than the exchange of Old Notes in connection with the Exchange Offer, then the amount of any such transfer tax (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering holder.

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF) AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE EXPIRATION DATE.

CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER

I certify under penalties of perjury that a taxpayer identification number has not been issued to me, and either (a) I have mailed or delivered an application to receive a taxpayer identification number to the appropriate Internal Revenue Service Center or Social Security Administration Office or (b) I intend to mail or deliver an application in the near future. I understand that if I do not provide a taxpayer identification number by the time of the exchange, all reportable payments made to me thereafter will be subject to backup withholding until I provide a number.

Guidelines for Determining the Proper Identification Number to Give the Payor — Social Security numbers have nine digits separated by two hyphens: i.e., 000-00-0000. Employer identification numbers have nine digits separated by only one hyphen: i.e., 00-0000000. The table below will help determine the name and number to give the Payor.

If you don’t have a taxpayer identification number or you don’t know your number, obtain Form SS-5. Application for a Social Security Number Card, or Form SS-4, Application for Employer Identification Number, at a local office of the Social Security Administration or the Internal Revenue Service and apply for a number. You may also obtain Form SS-4 by calling the IRS at 1-800-TAX-FORM.

Payees specifically exempted from backup withholding on ALL payments include the following:

Payees specifically exempted from backup withholding on interest and dividend payments include the following:

Payments of dividends and patronage dividends not generally subject to backup withholding include the following:

Payments of interest not generally subject to backup withholding include the following:

Exempt payees described above may file Form W-9 to avoid possible erroneous backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE “EXEMPT” ON THE FACE OF THE FORM, SIGN AND DATE THE FORM, AND RETURN IT TO THE PAYER.

Certain payments other than interest, dividends, and patronage dividends that are not subject to information reporting are also not subject to backup withholding. For details, see Sections 6041, 6041A, 6042, 6044, 6045, 6049, 6050A, 6050N, and their regulations.

Privacy Act Notice. Section 6109 requires most recipients of dividends, 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 and to help verify the accuracy of tax returns. The IRS also may provide this information to the Department of Justice for civil and criminal litigation and to cities, states, and the District of Columbia to carry out their tax laws. 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.

(1) Penalty for Failure to Furnish Taxpayer Identification Number. If you fail to furnish your 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 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.
