DELIVERY OF THIS LETTER OF TRANSMITTAL, ANY CONVERTIBLE NOTES AND OTHER REQUIRED DOCUMENTS TO THE DEPOSITORY TRUST COMPANY (“DTC”) DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

The instructions contained herein should be read carefully before this Letter of Transmittal is completed. All capitalized terms used but not defined herein shall have the meanings ascribed to them in the Offer to Purchase, dated November 20, 2012 (the “Offer to Purchase”).

This Letter of Transmittal and the instructions hereto (this “Letter of Transmittal”), the Offer to Purchase (together with this Letter of Transmittal, as amended and supplemented from time to time, the “Offer Documents”) constitute an offer (the “Offer”) by Orbital Sciences Corporation, a Delaware corporation (the “Company”), on the terms and subject to the conditions set forth in the Offer Documents, to purchase any and all outstanding Convertible Notes for the cash purchase price set forth in the Offer to Purchase. In addition, Holders (as defined below) will receive in respect of their Convertible Notes that are accepted for purchase accrued and unpaid interest on such Convertible Notes to, but excluding, the settlement date of the Offer. All amounts payable pursuant to the Offer will be rounded to the nearest cent. For further information regarding the purchase price, see “Terms of the Offer—Purchase Price” in the Offer to Purchase.

Only Convertible Notes validly tendered and not properly withdrawn prior to 12:00 midnight, New York City time, on the Expiration Date will be purchased in the Offer. The Company’s obligation to purchase Convertible Notes validly tendered and not properly withdrawn in the Offer is subject to the conditions described under “Conditions to the Offer” in the Offer to Purchase, including the satisfaction or waiver of the Financing Condition and certain other general conditions. Please read “Conditions to the Offer” in the Offer to Purchase.

Convertible Notes may be tendered only in denominations of $1,000 and any multiple thereof. No alternative, conditional or contingent tenders will be accepted.

All of the Convertible Notes are held in book-entry form, and are currently represented by one or more global certificates held for the account of DTC.

This Letter of Transmittal may be used by a DTC participant whose name appears on a security position listing as the owner of the Convertible Notes (each, a “Holder” and, collectively, the “Holders”) who desires to tender such Convertible Notes pursuant to the Offer. Pursuant to authority granted by DTC, if you are a DTC participant who has Convertible Notes credited to your DTC account, you may directly tender your Convertible Notes in the Offer as though you were a registered holder of the Convertible Notes. DTC participants that wish to accept the Offer may tender their Convertible Notes by (i) validly transmitting their acceptance to DTC through DTC’s Automated Tender Offer Program (“ATOP”) or (ii) completing, signing and dating this Letter of Transmittal according to the instructions set forth in the Offer Documents, delivering this Letter of Transmittal, together with any signature guarantees and any other documents required by this Letter of Transmittal, to the Depositary at its address listed on the back cover of this Letter of Transmittal, and ensuring that the Depositary receives, prior to 12:00 midnight, New York City time, on the Expiration Date, a timely confirmation of book-entry transfer of Convertible Notes into the Depositary’s account at DTC according to the procedure for book-entry transfer described below.

The Depositary and DTC have confirmed that Convertible Notes held in book-entry form through DTC that are to be tendered in the Offer are eligible for ATOP. To effectively tender Convertible Notes, DTC participants may until 5:00 P.M., New York City time, on December 18, 2012, in lieu of physically completing and signing this Letter of Transmittal and delivering it to the Depositary, electronically transmit their acceptance through ATOP, and DTC will then verify the acceptance, execute a book-entry delivery to the Depositary’s account at DTC and send an Agent’s Message to the Depositary for its acceptance. The confirmation of a book-entry transfer into the Depositary’s account at DTC as described above is referred to herein as a “Book-Entry Confirmation.” Delivery of documents to DTC does not constitute delivery to the Depositary. The term “Agent’s Message” means a message transmitted by DTC to, and received by, the Depositary and forming a part of the Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the DTC participant described in such Agent’s Message, stating that such participant has received and agrees to be bound by the terms and conditions of the Offer as set forth in the Offer Documents, and that the Company may enforce such agreement against such participant.

To effectively tender Convertible Notes after 5:00 P.M., New York City time, on December 18, 2012, but before 12:00 midnight, New York City time, on the Expiration Date, DTC participants may complete and sign a Letter of Transmittal and deliver the document via fax to the Depositary at its fax number on the back cover of this Letter of Transmittal on your behalf prior to 12:00 midnight, New York City time, on the Expiration Date, in accordance with the procedures described above. Immediately after delivering the document to the Depositary via fax, a DTC participant should telephone the Depositary at its telephone number listed on the back cover of this Letter of Transmittal to confirm the Depositary’s receipt of the document, to determine if further action is required and to confirm the Holder’s intent to tender Convertible Notes.

If your Convertible Notes are held of record through a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your Convertible Notes after 5:00 P.M., New York City time, on December 18, 2012, you must make arrangements with your nominee for such nominee to fax a Letter of Transmittal to the Depositary at its number on the back cover of this Letter of Transmittal on your behalf prior to 12:00 midnight, New York City time, on December 18, 2012, in accordance with the procedures described under “Procedures for Tendering Convertible Notes” in the Offer to Purchase.

If any validly tendered Convertible Notes are not purchased because the Offer is not completed, such unpurchased Convertible Notes will be returned without cost to the tendering holder promptly after the earlier of the termination or expiration of the Offer by book-entry delivery through DTC to the accounts of the Holders.

The Offer is made upon the terms and subject to the conditions set forth in the Offer Documents. Holders should carefully review the information set forth in the Offer Documents, including and “Purpose; Effects; Plans—Material Differences in the Rights of Convertible Note Holders as a Result of the Offer” in the Offer to Purchase, before making a decision with respect to the Offer.

The Offer is not being made to (nor will tenders of Convertible Notes be accepted from or on behalf of) Holders of Convertible Notes in any jurisdiction in which the making or acceptance of the Offer would not be in compliance with the laws of such jurisdiction. However, the Company, in its sole discretion, may take such action as it may deem necessary to make or extend the Offer in any such jurisdiction, provided that we will comply with the requirements of Rule 13e-4(f)(8) promulgated under the Exchange Act.

If you hold your Convertible Notes through a broker dealer, commercial bank, trust company or other nominee, you should contact such nominee promptly and instruct it to tender Convertible Notes on your behalf. The instructions included with this Letter of Transmittal must be followed.

Holders who wish to tender their Convertible Notes using this Letter of Transmittal must complete the box below entitled “Method of Delivery” and complete the box below entitled “Description of Convertible Notes Tendered” and sign in the appropriate box below.

NONE OF THE COMPANY, ITS MANAGEMENT OR BOARD OF DIRECTORS, THE DEALER MANAGERS, THE DEPOSITARY, THE TRUSTEE OR THE INFORMATION AGENT MAKES ANY RECOMMENDATION TO ANY HOLDER OF CONVERTIBLE NOTES AS TO WHETHER TO TENDER ANY CONVERTIBLE NOTES. NONE OF THE COMPANY, ITS MANAGEMENT OR BOARD OF DIRECTORS, THE DEALER MANAGERS, THE DEPOSITARY, THE TRUSTEE OR THE INFORMATION AGENT HAS AUTHORIZED ANY PERSON TO GIVE ANY INFORMATION OR TO MAKE ANY REPRESENTATION IN CONNECTION WITH THE OFFER OTHER THAN THE INFORMATION AND REPRESENTATIONS CONTAINED IN THE OFFER TO PURCHASE OR IN THIS LETTER OF TRANSMITTAL. IF ANYONE MAKES ANY RECOMMENDATION OR REPRESENTATION OR GIVES ANY SUCH INFORMATION, YOU SHOULD NOT RELY UPON THAT RECOMMENDATION, REPRESENTATION OR INFORMATION AS HAVING BEEN AUTHORIZED BY THE COMPANY, THE DEALER MANAGERS, THE DEPOSITARY, THE TRUSTEE OR THE INFORMATION AGENT.

THE COMPANY IS NOT PROVIDING FOR PROCEDURES FOR TENDERS OF CONVERTIBLE NOTES TO BE MADE BY GUARANTEED DELIVERY. ACCORDINGLY, HOLDERS MUST ALLOW SUFFICIENT TIME FOR THE NECESSARY TENDER PROCEDURES TO BE COMPLETED DURING THE NORMAL BUSINESS HOURS OF DTC ON OR PRIOR TO THE EXPIRATION DATE. IF YOU HOLD YOUR CONVERTIBLE NOTES THROUGH A BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY OR OTHER NOMINEE, YOU SHOULD CONSIDER THAT SUCH ENTITY MAY REQUIRE YOU TO TAKE ACTION WITH RESPECT TO THE OFFER A NUMBER OF DAYS BEFORE THE EXPIRATION DATE IN ORDER FOR SUCH ENTITY TO TENDER CONVERTIBLE NOTES ON YOUR BEHALF ON OR PRIOR TO THE EXPIRATION DATE. TENDERS NOT COMPLETED PRIOR TO 12:00 MIDNIGHT, NEW YORK CITY TIME, ON THE EXPIRATION DATE WILL BE DISREGARDED AND OF NO EFFECT.

The names and addresses of the Holders should be printed exactly as they appear on a security position listing showing such participant as the owner of the Convertible Notes. No alternative, conditional or contingent tenders will be accepted.

If you do not wish to tender your Convertible Notes, you do not need to return this Letter of Transmittal or take any other action.

The undersigned understands that tenders of Convertible Notes pursuant to any of the procedures described in the Offer Documents and acceptance thereof by the Company will constitute a binding agreement between the undersigned and the Company upon the terms and subject to the conditions of the Offer, which agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or the Company to be necessary or desirable to complete the tender, sale, assignment, transfer and delivery of the Convertible Notes tendered thereby.

4. Special Payment and Special Delivery Instructions. Tendering Holders should indicate in the applicable box or boxes the name, address and account to which Convertible Notes not accepted for purchase or checks for payment of the purchase price for validly tendered and accepted Convertible Notes and any Accrued Interest that are to be issued in connection with the Offer are to be credited, issued or delivered, as applicable, if different from the name, address or account of the Holder signing this Letter of Transmittal. In the case checks are issued or Convertible Notes are credited to a different name, the taxpayer identification number or social security number (collectively, the “TIN”) of the person named must also be indicated and satisfactory evidence of the payment of transfer taxes or exemption therefrom must be submitted. If no instructions are given (a) checks for

payment of the purchase price and any Accrued Interest to be issued in connection with the Offer will be issued to and (b) Convertible Notes not tendered or not accepted for purchase will be credited back to, such DTC participant’s account. The Company has no obligation pursuant to the “Special Payment Instructions” box or “Special Delivery Instructions” box to transfer any Convertible Notes from the name of the Holder(s) thereof if the Company does not accept for purchase any of such Convertible Notes or if the Holder(s) does not present satisfactory evidence of payment of any taxes that may be payable as a consequence of the payment or delivery requested by the Holder(s) completing the “Special Payment Instructions” and/or “Special Delivery Instructions” boxes.

5. Important Tax Information. Each tendering Holder that is a United States person (a “U.S. Holder”) is required to provide the Depositary with the Holder’s correct taxpayer identification number (“TIN”) on Form W-9 (the “Form”), which is provided below, or must establish another basis for exemption from backup withholding. Generally, a U.S. Holder’s TIN will be such U.S. Holder’s social security or federal employer identification number. A U.S. Holder must cross out item (2) under Part 2 of the Form if such U.S. Holder is subject to backup withholding. The box under Part 3 of the Form should be checked if the tendering U.S. 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 under Part 3 of the Form is checked and the Depositary is not provided with a TIN, the Depositary will withhold the applicable backup withholding amount from all such payments with respect to the Notes to be purchased until a TIN is provided to the Depositary. If the U.S. Holder furnishes the Depositary with its TIN within 60 days after the date of the Form, the amounts retained during the 60-day period will be remitted to the U.S. Holder. If, however, the Depositary does not receive a TIN within 60 days of the Depositary’s receipt of the Form, the withheld amount will be remitted to the Internal Revenue Service (“IRS”). Exempt U.S. Holders should furnish their TIN, write “Exempt” on the face of the Form, and sign, date and return the Form to the Depositary.

See the enclosed “Guidelines for Certification of Taxpayer Identification Number on Form W-9” for further detailed instructions and information.

A Holder that is a foreign person, including a foreign entity, generally is exempt from backup withholding. In order to establish an exemption, a Holder that is a foreign person must submit to the Depositary an appropriate, properly completed IRS Form W-8 signed under penalties of perjury, certifying to that Holder’s foreign status. An appropriate IRS Form W-8 can be obtained from the Information Agent or directly from the IRS at its Internet site at http://www.irs.gov.

If backup withholding applies, the Depositary is required to withhold the applicable backup withholding amount from any payments made by the Company to the Holder or other payee. Backup withholding is not an additional U.S. federal income tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of U.S. federal income tax, a refund may be obtained from the IRS, provided the required information is timely furnished to the IRS.

Failure to provide the Depositary with a Holder’s correct TIN may subject the tendering Holder to a $50 fine imposed by the IRS, and payments made with respect to such Holder’s Convertible Notes purchased pursuant to the Offer may be subject to applicable federal income tax backup withholding. Failure to comply truthfully with the backup withholding requirements may result in the imposition of criminal and/or civil fines and penalties.

6. Transfer Taxes. The Company will pay all transfer taxes applicable to the purchase and transfer of Convertible Notes pursuant to the Offer except in the case of deliveries of certificates for Convertible Notes for principal amounts not tendered or not accepted for payment that are registered or issued in the name of any person other than the registered Holder of Convertible Notes tendered hereby. Except as provided in this Instruction 6, it will not be necessary for transfer stamps to be affixed to the certificates listed in this Letter of Transmittal.

7. Irregularities. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tendered Convertible Notes pursuant to any of the procedures described above and the form

and validity (including time of receipt of notices of withdrawal) of all documents will be determined by the Company. The Company reserves the absolute right to reject any or all tenders of any Convertible Notes determined by it not to be in proper form or if the acceptance of or payment for such Notes may, based on the advice of the Company’s counsel, be unlawful. The Company also reserves the absolute right, in its sole discretion, to waive or amend any condition to the Offer that it is legally permitted to waive or amend and waive any defect or irregularity in any tender with respect to Notes of any particular Holder, whether or not similar defects or irregularities are waived in the case of other Holders. In the event that a condition is waived with respect to any particular Holder, the same condition will be waived with respect to all Holders. None of the Company, the Depositary, the Trustee, the Dealer Managers, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or will incur any liability for failure to give any such notification. If the Company waives its right to reject a defective tender of Convertible Notes, the Holder will be entitled to the purchase price.

8. Waiver of Conditions. The Company expressly reserves the absolute right, in its sole discretion, to waive any of the conditions of the Offer in the case of any Convertible Notes tendered, in whole or in part, at any time and from time to time. If a condition is waived with respect to one tender, the same condition will be waived with respect to all tenders.

9. Requests for Assistance or Additional Copies. Questions and requests for assistance relating to the procedures for tendering Convertible Notes and requests for additional copies of the Offer to Purchase and this Letter of Transmittal may be directed to the Information Agent at the address and telephone numbers listed on the back cover of this Letter of Transmittal. Questions regarding the terms of the Offer may also be directed to the Dealer Managers at the addresses and telephone numbers listed on the back cover of this Letter of Transmittal.

Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and, when applicable, to:

1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued),

2. Certify that you are not subject to backup withholding, or

3. Claim exemption from backup withholding if you are a U.S. exempt payee. If applicable, you are also certifying that as a U.S. person, your allocable share of any partnership income from a U.S. trade or business is not subject to the withholding tax on foreign partners’ share of effectively connected income.

Note. If a requester gives you a form other than Form W-9 to request your TIN, you must use the requester’s form if it is substantially similar to this Form W-9.

Definition of a U.S. person. For federal tax purposes, you are considered a U.S. person if you are:

— An individual who is a U.S. citizen or U.S. resident alien,

— A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States,

— An estate (other than a foreign estate), or

— A domestic trust (as defined in Regulations section 301.7701-7).

Special rules for partnerships. Partnerships that conduct a trade or business in the United States are generally required to pay a withholding tax on any foreign partners’ share of income from such business. Further, in certain cases where a Form W-9 has not been received, a partnership is required to presume that a partner is a foreign person, and pay the withholding tax. Therefore, if you are a U.S. person that is a partner in a partnership conducting a trade or business in the United States, provide Form W-9 to the partnership to establish your U.S. status and avoid withholding on your share of partnership income.

The person who gives Form W-9 to the partnership for purposes of establishing its U.S. status and avoiding withholding on its allocable share of net income from the partnership conducting a trade or business in the United States is in the following cases:

— The U.S. owner of a disregarded entity and not the entity,

— The U.S. grantor or other owner of a grantor trust and not the trust, and

— The U.S. trust (other than a grantor trust) and not the beneficiaries of the trust.

Foreign person. If you are a foreign person, do not use Form W-9. Instead, use the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities).

Nonresident alien who becomes a resident alien.

Generally, only a nonresident alien individual may use the terms of a tax treaty to reduce or eliminate U.S. tax on certain types of income. However, most tax treaties contain a provision known as a “saving clause.” Exceptions specified in the saving clause may permit an exemption from tax to continue for certain types of income even after the payee has otherwise become a U.S. resident alien for tax purposes.

If you are a U.S. resident alien who is relying on an exception contained in the saving clause of a tax treaty to claim an exemption from U.S. tax on certain types of income, you must attach a statement to Form W-9 that specifies the following five items:

1. The treaty country. Generally, this must be the same treaty under which you claimed exemption from tax as a nonresident alien.

2. The treaty article addressing the income.

3. The article number (or location) in the tax treaty that contains the saving clause and its exceptions.

4. The type and amount of income that qualifies for the exemption from tax.

5. Sufficient facts to justify the exemption from tax under the terms of the treaty article.

Example. Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under U.S. law, this student will become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April 30, 1984) allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States. A Chinese student who qualifies for this exception (under paragraph 2 of the first protocol) and is relying on this exception to claim an exemption from tax on his or her scholarship or fellowship income would attach to Form W-9 a statement that includes the information described above to support that exemption.

If you are a nonresident alien or a foreign entity not subject to backup withholding, give the requester the appropriate completed Form W-8.

What is backup withholding? Persons making certain payments to you must under certain conditions withhold and pay to the IRS a percentage of such payments. This is called “backup withholding.” Payments that may be subject to backup withholding include interest, tax-exempt interest, dividends, broker and barter exchange transactions, rents, royalties, nonemployee pay, and certain payments from fishing boat operators. Real estate transactions are not subject to backup withholding.

You will not be subject to backup withholding on payments you receive if you give the requester your correct TIN, make the

proper certifications, and report all your taxable interest and dividends on your tax return.

Payments you receive will be subject to backup withholding if:

1. You do not furnish your TIN to the requester,

2. You do not certify your TIN when required (see the Part II instructions on page 3 for details),

3. The IRS tells the requester that you furnished an incorrect TIN,

4. The IRS tells you that you are subject to backup withholding because you did not report all your interest and dividends on your tax return (for reportable interest and dividends only), or

5. You do not certify to the requester that you are not subject to backup withholding under 4 above (for reportable interest and dividend accounts opened after 1983 only).

Certain payees and payments are exempt from backup withholding. See the instructions below and the separate Instructions for the Requester of Form W-9.

Also see Special rules for partnerships on page 1.

Updating Your Information

You must provide updated information to any person to whom you claimed to be an exempt payee if you are no longer an exempt payee and anticipate receiving reportable payments in the future from this person. For example, you may need to provide updated information if you are a C corporation that elects to be an S corporation, or if you no longer are tax exempt. In addition, you must furnish a new Form W-9 if the name or TIN changes for the account, for example, if the grantor of a grantor trust dies.

Penalties

Failure to furnish TIN. If you fail to furnish your correct TIN to a requester, 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.

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.

Criminal penalty for falsifying information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

Specific Instructions

Name

If you are an individual, you must generally enter the name shown on your income tax return. However, if you have changed your last name, for instance, due to marriage without informing the Social Security Administration of the name change, enter your first name, the last name shown on your social security card, and your new last name.

If the account is in joint names, list first, and then circle, the name of the person or entity whose number you entered in Part I of the form.

Sole proprietor. Enter your individual name as shown on your income tax return on the “Name” line. You may enter your business, trade, or “doing business as (DBA)” name on the “Business name/disregarded entity name” line.

Partnership, C Corporation, or S Corporation. Enter the entity’s name on the “Name” line and any business, trade, or “doing business as (DBA) name” on the “Business name/disregarded entity name” line.

Disregarded entity. Enter the owner’s name on the “Name” line. The name of the entity entered on the “Name” line should never be a disregarded entity. The name on the “Name” line must be the name shown on the income tax return on which the income will be reported. For example, if a foreign LLC that is treated as a disregarded entity for U.S. federal tax purposes has a domestic owner, the domestic owner’s name is required to be provided on the “Name” line. If the direct owner of the entity is also a disregarded entity, enter the first owner that is not disregarded for federal tax purposes. Enter the disregarded entity’s name on the “Business name/disregarded entity name” line. If the owner of the disregarded entity is a foreign person, you must complete an appropriate Form W-8.

Note. Check the appropriate box for the federal tax classification of the person whose name is entered on the “Name” line (Individual/sole proprietor, Partnership, C Corporation, S Corporation, Trust/estate).

Limited Liability Company (LLC). If the person identified on the “Name” line is an LLC, check the “Limited liability company” box only and enter the appropriate code for the tax classification in the space provided. If you are an LLC that is treated as a partnership for federal tax purposes, enter “P” for partnership. If you are an LLC that has filed a Form 8832 or a Form 2553 to be taxed as a corporation, enter “C” for C corporation or “S” for S corporation. If you are an LLC that is disregarded as an entity separate from its owner under Regulation section 301.7701-3 (except for employment and excise tax), do not check the LLC box unless the owner of the LLC (required to be identified on the “Name” line) is another LLC that is not disregarded for federal tax purposes. If the LLC is disregarded as an entity separate from its owner, enter the appropriate tax classification of the owner identified on the “Name” line.

Other entities. Enter your business name as shown on required federal tax documents on the “Name” line. This name should match the name shown on the charter or other legal document creating the entity. You may enter any business, trade, or DBA name on the “Business name/ disregarded entity name” line.

Exempt Payee

If you are exempt from backup withholding, enter your name as described above and check the appropriate box for your status, then check the “Exempt payee” box in the line following the “Business name/ disregarded entity name,” sign and date the form.

Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations are exempt from backup withholding for certain payments, such as interest and dividends.

Note. If you are exempt from backup withholding, you should still complete this form to avoid possible erroneous backup withholding.

The following payees are exempt from backup withholding:

1. An organization exempt from tax under section 501(a), any IRA, or a custodial account under section 403(b)(7) if the account satisfies the requirements of section 401(f)(2),

2. The United States or any of its agencies or instrumentalities,

3. A state, the District of Columbia, a possession of the United States, or any of their political subdivisions or instrumentalities,

4. A foreign government or any of its political subdivisions, agencies, or instrumentalities, or

5. An international organization or any of its agencies or instrumentalities.

Other payees that may be exempt from backup withholding include:

6. A corporation,

7. A foreign central bank of issue,

8. A dealer in securities or commodities required to register in the United States, the District of Columbia, or a possession of the United States,

9. A futures commission merchant registered with the Commodity Futures Trading Commission,

10. A real estate investment trust,

14. A middleman known in the investment community as a nominee or custodian, or

15. A trust exempt from tax under section 664 or described in section 4947.

The following chart shows types of payments that may be exempt from backup withholding. The chart applies to the exempt payees listed above, 1 through 15.


IF the payment is for...		THEN the payment is exempt for...
Interest and dividend payments		All exempt payees except for 9

¹	See Form 1099-MISC, Miscellaneous Income, and its instructions.

²	However, the following payments made to a corporation and reportable on Form 1099-MISC are not exempt from backup withholding: medical and health care payments, attorneys’ fees, gross proceeds paid to an attorney, and payments for services paid by a federal executive agency.

Part I. Taxpayer Identification Number (TIN)

Enter your TIN in the appropriate box. If you are a resident alien and you do not have and are not eligible to get an SSN, your TIN is your IRS individual taxpayer identification number (ITIN). Enter it in the social security number box. If you do not have an ITIN, see How to get a TIN below.

If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN. However, the IRS prefers that you use your SSN.

If you are a single-member LLC that is disregarded as an entity separate from its owner (see Limited Liability Company (LLC) on page 2), enter the owner’s SSN (or EIN, if the owner has one). Do not enter the disregarded entity’s EIN. If the LLC is classified as a corporation or partnership, enter the entity’s EIN.

Note. See the chart on page 4 for further clarification of name and TIN combinations.

How to get a TIN. If you do not have a TIN, apply for one immediately. To apply for an SSN, get Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at www.ssa.gov. You may also get this form by calling 1-800-772-1213. Use Form W-7, Application for IRS Individual Taxpayer Identification Number, to apply for an ITIN, or Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses and clicking on Employer Identification Number (EIN) under Starting a Business. You can get Forms W-7 and SS-4 from the IRS by visiting IRS.gov or by calling 1-800-TAX-FORM (1-800-829-3676).

If you are asked to complete Form W-9 but do not have a TIN, write “Applied For” in the space for the TIN, sign and date the

form, and give it to the requester. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.

Note. Entering “Applied For” means that you have already applied for a TIN or that you intend to apply for one soon.

Caution: A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.

Part II. Certification

To establish to the withholding agent that you are a U.S. person, or resident alien, sign Form W-9. You may be requested to sign by the withholding agent even if item 1, below, and items 4 and 5 on page 4 indicate otherwise.

For a joint account, only the person whose TIN is shown in Part I should sign (when required). In the case of a disregarded entity, the person identified on the “Name” line must sign. Exempt payees, see Exempt Payee on page 3.

Signature requirements. Complete the certification as indicated in items 1 through 3, below, and items 4 and 5 on page 4.

1. Interest, dividend, and barter exchange accounts opened before 1984 and broker accounts considered active during 1983. You must give your correct TIN, but you do not have to sign the certification.

2. Interest, dividend, broker, and barter exchange accounts opened after 1983 and broker accounts considered inactive during 1983. You must sign the certification or backup withholding will apply. If you are subject to backup withholding and you are merely providing your correct TIN to the requester, you must cross out item 2 in the certification before signing the form.

3. Real estate transactions. You must sign the certification. You may cross out item 2 of the certification.

4. Other payments. You must give your correct TIN, but you do not have to sign the certification unless you have been notified that you have previously given an incorrect TIN. “Other payments” include payments made in the course of the requester’s trade or business for rents, royalties, goods (other than bills for merchandise), medical and health care services (including payments to corporations), payments to a nonemployee for services, payments to certain fishing boat crew members and fishermen, and gross proceeds paid to attorneys (including payments to corporations).

5. Mortgage Interest paid by you, acquisition or abandonment of secured property, cancellation of debt, qualified tuition program payments (under section 529), IRA, Coverdell ESA, Archer MSA or HSA contributions or distributions, and pension distributions. You must give your correct TIN, but you do not have to sign the certification.

Secure Your Tax Records from Identity Theft

Identity theft occurs when someone uses your personal information such as your name, social security number (SSN), or other identifying information, without your permission, to commit fraud or other crimes. An identity thief may use your SSN to get a job or may file a tax return using your SSN to receive a refund.

To reduce your risk:

•

Protect your SSN,

•

Ensure your employer is protecting your SSN, and

•

Be careful when choosing a tax preparer.

If your tax records are affected by identity theft and you receive a notice from the IRS, respond right away to the name and phone number printed on the IRS notice or letter.

If your tax records are not currently affected by identity theft but you think you are at risk due to a lost or stolen purse or wallet, questionable credit card activity or credit report, contact the IRS Identity Theft Hotline at 1-800-908-4490 or submit Form 14039.

For more information, see Publication 4535, Identity Theft Prevention and Victim Assistance.

Victims of identity theft who are experiencing economic harm or a system problem, or are seeking help in resolving tax problems that have not been resolved through normal channels, may be eligible for Taxpayer Advocate Service (TAS) assistance. You can reach TAS by calling the TAS toll-free case intake line at 1-877-777-4778 or TTY/TDD 1-800-829-4059.

Protect yourself from suspicious emails or phishing schemes. Phishing is the creation and use of email and websites designed to mimic legitimate business emails and websites. The most common act is sending an email to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.

The IRS does not initiate contacts with taxpayers via emails. Also, the IRS does not request personal detailed information through email or ask taxpayers for the PIN numbers, passwords, or similar secret access information for their credit card, bank, or other financial accounts.

If you receive an unsolicited email claiming to be from the IRS, forward this message to phishing@irs.gov. You may also report misuse of the IRS name, logo, or other IRS property to the Treasury Inspector General for Tax Administration at 1-800-366-4484. You can forward suspicious emails to the Federal Trade Commission at: spam@uce.gov or contact them at www.ftc.gov/idtheft or 1-877-IDTHEFT (1-877-438-4338).

Visit IRS.gov to learn more about identity theft and how to reduce your risk.

Section 6109 of the Internal Revenue Code requires you to provide your correct TIN to persons (including federal agencies) who are required to file information returns with the IRS to report interest, dividends, or certain other income paid to you; mortgage interest you paid; the acquisition or abandonment of secured property; the cancellation of debt; or contributions you made to an IRA, Archer MSA, or HSA. The person collecting this form uses the information on the form to file information returns with the IRS, reporting the above information. Routine uses of this information include giving it to the Department of Justice for civil and criminal litigation and to cities, states, the District of Columbia, and U.S. possessions for use in administering their laws. The information also may be disclosed to other countries under a treaty, to federal and state agencies to enforce civil and criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. You must provide your TIN whether or not you are required to file a tax return. Under section 3406, payers must generally withhold a percentage of taxable interest, dividend, and certain other payments to a payee who does not give a TIN to the payer. Certain penalties may also apply for providing false or fraudulent information.
