Common use of Certain U Clause in Contracts

Certain U. S. Shareholders (such as corporations and individual retirement accounts) are not subject to backup withholding but may be required to provide evidence of their exemption from backup withholding. Exempt U.S. Shareholders should enter the appropriate exempt payee code on IRS Form W-9. See the enclosed IRS Form W-9 for instructions. A U.S. Shareholder that is not a U.S. person and is not acting on behalf of a U.S. person should not complete IRS Form W-9. Instead, to establish an exemption from backup withholding, such U.S. Shareholder should properly complete and submit an IRS Form W-8BEN, W-8BEN-E, W-8IMY, W-8ECI, or W-8EXP, as applicable, attesting to such exempt status. An appropriate IRS Form W-8 may be obtained from the Transfer Agent or on the IRS website (w▇▇.▇▇▇.▇▇▇).
