             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 one hyphen: e.g., 00-0000000. The table below will
help determine the number to give the payer.

Obtaining a Number

If you do not 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 the local office of the
Social Security Administration or the Internal Revenue Service (the "IRS") and
apply for a number.

In some cases, individuals who become U.S. resident aliens for tax purposes, are
not eligible to obtain an SSN. This includes certain resident aliens who must
receive information returns but who cannot obtain an SSN. These individuals must
apply for an Individual Taxpayer Identification Number ("ITIN") on Form W-7,
Application for IRS Individual Taxpayer Identification Number, unless they have
an application pending for an SSN. Individuals who have an ITIN must provide it
on Form W-9.

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

The following is a list of payees that are or may be exempt from backup
withholding and for which no information reporting is required. For interest and
dividends, all listed payees 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.
Payments subject to reporting under sections 6041 and 6041A are generally exempt
from backup withholding only if made to payees described in items (1) through
(7), except that a corporation that provides medical and health care services or
bills and collects payments for such services is not exempt from backup
withholding or information reporting. Only payees described in items (1) through
(5) are exempt from backup withholding for barter exchange transactions,
patronage dividends and payments by certain fishing boat operators.

(1)  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).

(2)  The United States or any of its agencies or instrumentalities.

     Note: You may be subject to backup withholding if this interest is $600 or
     more and is paid in the course of the payer's trade or business and you
     have not provided your correct taxpayer identification number to the payer.

..    Payments of tax-exempt interest (including exempt interest dividends under
     section 852).

..    Payments described in section 6049(b)(5) to nonresident aliens.

6049, 6050A and 6050N and the regulations under such sections.

Exempt payees described above should file 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 Notices

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 of 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 qualified to file a tax return. Payers must generally withhold 30% 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.

Penalties

(1)  Penalty for Failure to Furnish Taxpayer Identification Number. If you fail
     to furnish your correct 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 $500 penalty.

(3)  Criminal Penalty for Falsifying Information

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