REQUEST FOR TAXPAYER IDENTIFICATION AND CERTIFICATION
Our records indicate that we do not have a certified Taxpayer Identification Number (TIN) on file. Without a certified TIN, we may be required by law to withhold 28% from any sale transaction that you request. Logon to www.melloninvestor.com/isd to certify your TIN, or contact us by phone to request a Substitute Form W-9.
If you are exempt from backup withholding, remember to indicate that when completing the certification.
