GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION

NUMBER ON SUBSTITUTE FORM W-9

Guidelines for Determining the Proper Identification Number to Give the Payer. The taxpayer identification number for an individual is the individual’s Social Security number. Social Security numbers have nine digits separated by two hyphens: e.g., 000-00-0000. The taxpayer identification number for an entity is the entity’s Employer Identification number. Employer Identification numbers have nine digits separated by only one hyphen: e.g., 00-0000000. The table below will help determine the number to give the payer.

1.      An individual’s account	The individual
2.      Two or more individuals (joint account)	The actual owner of the account or, if combined funds, the first individual on the account(1)

5.      Sole proprietorship or single-owner LLC owned by an individual	The owner(3)
For this type of account:	Give the EMPLOYER IDENTIFICATION number of—
6.      Single-owner LLC account not owned by an individual	The owner
7.      A valid trust, estate or pension trust	The legal entity (Do not furnish the identifying number of the personal representative or trustee unless the legal entity itself is not designated in the account title.)(4)
8.      Corporate account or LLC electing corporate status on form 8832 account	The corporation

(3) You must show the name of the individual. The name of the business or the “doing business as” name may also be entered. Either the Social Security number or the Employer Identification number may be used.

Section References Are To The Internal Revenue Code.

Obtaining a Number

If you do not have a taxpayer identification number or you do not know your number, obtain Form SS-5, Application for a Social Security Number Card, or Form SS-4, Application for Employer Identification Number, at the local office of the Social Security Administration or the Internal Revenue Service (the “IRS”) and apply for a number.

To complete the Substitute Form W-9, if you do not have a taxpayer identification number, write “Applied For” in the space for the taxpayer identification number in Part 1, sign and date the Form, and give it to the requester. If the requester does not receive your taxpayer identification number within 60 days, backup withholding, if applicable, will begin and will continue until you furnish your taxpayer identification number to the requester.

Payees Exempt from Backup Withholding

For certain payees, exemptions from backup withholding apply and no information reporting is required. For interest, all payees listed below are exempt except item (9). For broker transactions, payees listed in (1) through (13) and a person registered under the Investment Advisers Act of 1940 who regularly acts as a broker are exempt.

(1) A corporation.

(2) An organization exempt from tax under section 501(a), or an individual retirement plan (“IRA”), or a custodial account under 403(b)(7), if the account satisfies the requirements of section 401(f)(2).

(4) A State, the District of Columbia, a possession of the United States, or any of its political subdivisions or instrumentalities.

Payments that are not subject to information reporting are also not subject to backup withholding. For details see sections 6041, 6041A(a), 6042, 6044, 6045, 6049, 6050A and 6050N, and the regulations under those sections.

Exempt payees described above should provide a Substitute Form W-9 to avoid possible erroneous backup withholding. ENTER YOUR TAXPAYER IDENTIFICATION NUMBER. WRITE “EXEMPT” ON THE FACE OF THE FORM, SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.

Privacy Act Notice

Section 6109 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, mortgage interest you paid, the acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA. 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. The IRS may also disclose this information to other countries under a tax treaty, or to federal and state agencies to enforce federal non-tax criminal laws and to combat terrorism.

You must provide your taxpayer identification number whether or not you are required to file a tax return. Payers must generally withhold (currently at a rate of 28%) on 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 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 backup withholding, you are subject to a $500 penalty.

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