Exhibit 99.7
                                                                    ------------

                            IMPORTANT TAX INFORMATION

         Under United States federal income tax law, dividend payments and other
distributions that may be made by the Company on shares of Common Stock issued
upon the exercise of Rights may be subject to backup withholding and each Rights
holder who exercises Rights should provide the Company with such Rights holder's
correct Taxpayer Identification Number ("TIN") on Substitute Form W-9 below. If
such Rights holder is an individual, the TIN is his or her Social Security
Number ("SSN"). If the Company is not provided with the correct TIN in
connection with such payments, the Rights holder may be subject to a $50.00
penalty imposed by the Internal Revenue Service (the "IRS").

         Exempt Rights holders (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. In general, in order for a foreign individual to qualify
as an exempt recipient, such Rights holder must submit a statement, signed under
the penalties of perjury, attesting to that individual's exempt status. Such
statements can be obtained from the Company. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.

         If backup withholding applies, the Company will be required to withhold
31% of any such payments made to the Rights holder. Backup withholding is not an
additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained.

Purpose of Substitute Form W-9
- ------------------------------

         A person who is required to file an information return with the IRS
must get your TIN to report, for example, income paid to you. Use Form W-9 to
give your correct TIN to the payer (the person requesting your TIN) and, when
applicable, (1) to certify that the TIN you are using is correct (or that you
are waiting for a number to be issued), (2) to certify that you are not subject
to backup withholding or (3) to claim exemption from backup withholding if you
are an exempt payee. To prevent backup withholding, a Rights holder is required
to notify the Company of such Rights holder's correct TIN by completing the form
below certifying that the TIN provided on Substitute Form W- 9 is correct (or
that such Rights holder is awaiting a TIN).

NOTE: If a payer gives you a form other than a Form W-9 to request your TIN, you
must use the payer's form if it is substantially similar to Form W-9.

What Is Backup Withholding?
- ---------------------------

         Persons making certain payments to you must withhold and pay to the IRS
31% of such payments under certain conditions. This is called "backup
withholding." Payments that may be subject to backup withholding include
interest, dividends, broker and barter exchange transactions, rents, royalties,
non-employee pay, and certain payments from fishing boat operators. Real estate
transactions are not subject to backup withholding. If you give the payer your
correct TIN, make proper certifications, and report all your taxable interest
and dividends on your tax return, payments you receive will not be subject to
backup withholding. Payments you receive WILL be subject to backup withholding
if:


1.   you do not furnish your TIN to the payer, or
2.   the IRS tells the payer that you furnished an incorrect TIN, or
3.   the IRS tells you that you are subject to backup withholding because you
     did not report all your interest and dividends on your tax return (for
     reportable interest and dividends only), or
4.   you did not certify to the payer that you are not subject to backup
     withholding under 3 above (for reportable interest and dividend accounts
     opened after 1983 only), or
5.   you did not certify your TIN when required. See the chart below for
     details.

Certain payees and payments are exempt from backup withholding and information
reporting. See below.


What Number to Give the Company?
- --------------------------------

         Each Rights holder is required to give the Company the SSN or Employer
Identification Number ("EIN") of the record owner of the Rights. If the Rights
are in more than one name or are not in the name of the actual owner, consult
the enclosed Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9 for additional guidelines on which number to report.
