NUMBER AND CERTIFICATION ON SUBSTITUTE FORM W-9

What Name and Number to Give the Requester

Name

        If you are an individual, you must generally enter the name shown on your Social Security card. 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 enter in Part I of the form.

        Sole Proprietor—You must enter your individual name as shown on your Social Security card. You may enter your business, trade or "doing business as" name on the business name line.

        Limited Liability Company (LLC)—If you are a single-member LLC (including a foreign LLC with a domestic owner) that is disregarded as an entity separate from its owner under Treasury regulations § 301.7701-3, enter the owner's name. Enter the LLC's name on the business name line. A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.

        Other Entities—Enter the business name as shown on required federal income tax documents. This name should match the name shown on the charter or other legal document creating the entity. You may enter any business, trade or "doing business as" name on the business name line.

Taxpayer Identification Number (TIN)

        You must enter your taxpayer identification number in the appropriate box. 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). Enter it in the Social Security number box. If you do not have an individual taxpayer identification number, see How to Get a TIN below. If you are a sole proprietor and you have an employer identification number, you may enter either your Social Security number or employer identification number. However, using your employer identification number may result in unnecessary notices to the requester, and the IRS prefers that you use your Social Security number. If you are an LLC that is disregarded as an entity separate from its owner under Treasury regulations § 301.7701-3, and are owned by an individual, enter the owner's Social Security number. If the owner of a disregarded LLC is a corporation, partnership, etc., enter the owner's employer identification number. See the chart below for further clarification of name and TIN combinations.

        Social Security numbers (SSN's) have nine digits separated by two hyphens: i.e. 000-00-0000. Employer identification numbers (EIN's) have nine digits separated by only one hyphen: i.e. 00-0000000.

        The table below will help determine the number to give the requester.

How to Get a TIN

If you do not have a taxpayer identification number, apply for one immediately. To apply for a Social Security number, get Form SS-5, Application for a Social Security Number Card, from your local Social Security Administration office. Get Form W-7 to apply for an individual taxpayer identification number or Form SS-4, Application for Employer Identification Number, to apply for an employer identification number. You can get Forms W-7 and SS-4 from the IRS.

        If you do not have a taxpayer identification number, write "Applied For" in the space for the taxpayer identification number, sign and date the form (including the Certificate of Awaiting Taxpayer Identification Number), and give it to the requester. For interest and dividend payments and certain payments made with respect to readily tradable instruments, you will generally have 60 days to get a taxpayer identification number and give it to the requester before you are subject to backup withholding. Other payments are subject to backup withholding without regard to the 60-day rule, until you provide your taxpayer identification number.

Note: Writing "Applied For" means that you have already applied for a taxpayer identification number or that you intend to apply for one soon.

Note, however, that such a payment may be subject to backup withholding if the amount of interest paid during a taxable year in the course of the payor's trade or business is $600 or more, and you have not provided your correct taxpayer identification number or you have provided an incorrect taxpayer identification number to the payer.

If you are exempt from backup withholding, you should still complete and file Substitute Form W-9 to avoid possible erroneous backup withholding. Enter your correct taxpayer identification number in Part 1, write "Exempt" in Part 2, and sign and date the form and return it to the requester.

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

Privacy Act Notice.—Section 6109 of the Code requires you to give your correct taxpayer identification number to persons who must file information returns with the IRS to report interest, dividends and certain other income paid to you. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS may also 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. You must provide your taxpayer identification number whether or not you are required to file a tax return. Payers must generally withhold at the applicable rate on payments of taxable interest, dividends and certain other items to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1)

Failure to Furnish Taxpayer Identification Number.—If you fail to furnish your correct taxpayer identification number to a requester, you are subject to a penalty of $50.00 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 backup withholding, you are subject to a $500.00 penalty.

(3)

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