               GUIDELINES FOR REQUEST FOR TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9



WHAT NAME AND NUMBER TO GIVE THE PAYER

         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 ss. 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 payer, 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 ss.
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 payer.
