* 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.

(1) List first and circle the name of the person whose number you furnish. If only one person on a joint account has a social security number, that person’s number must be furnished.

(2) Circle the minor’s name and furnish the minor’s social security number.

(3) Show the individual name of the owner. If the owner does not have an employer identification number, furnish the owner’s social security number.

(4) List first and circle the name of the legal trust, estate or pension trust.

NOTE: If no name is circled when there is more than one name, the number will be considered to be that of the first name listed.

Obtaining a Number

If you do not have a taxpayer identification number (or “TIN”) or you do not know your number, obtain form SS-5, Application for a Social Security Number Card (for resident individuals), Form SS-4, Application for Employer Identification Number (for businesses and all other entities), Form W-7 for International Taxpayer Identification Number (for alien individuals required to file U.S. tax returns). You may obtain Form SS-5 from your local Social Security Administration Office and Forms SS-4 and W-7 from the IRS by calling 1-800-TAX-FORM (1-800-829-3676) or from the IRS’s Internet Web Site at www.irs.gov.

If you do not have a TIN and have applied for a number or intend to apply for a number in the near future, check the box provided in Part 2 on Substitute Form W-9, sign and date the form and the Certificate of Payee Awaiting Taxpayer Identification Number and return them to the Company. If such certificate is completed and you do not provide the TIN by the time of payment, the payee will withhold 28% of all payments made to you. Note: Writing “Applied For” means that you have already applied for a TIN OR that you intend to apply for one soon.
