Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Declaration of Trust.

For the purpose of this notice, the “Redemption Price” shall mean a Pro Rata amount for which the Trust Preferred Securities will be redeemed, which amount will be the lesser of:

(i) the redemption price paid by the Partnership (including premium, if any, payable under the Partnership Agreement) to redeem, in whole or in part, the Partnership Preferred Securities held by the Trust plus an amount equal to accrued and unpaid Distributions (if any, without duplication) on such Trust Securities through their date of redemption;

AND

(ii) the amount received by the Trust in respect of the Partnership Preferred Securities so redeemed.

Holders of the Trust Preferred Securities will be paid the Redemption Price upon presentation and surrender of their Trust Preferred Securities for redemption at the following addresses:

On the Redemption Date, (i) the Redemption Price will become due and payable on the Trust Preferred Securities, (ii) unless the Company defaults in making payment of the Redemption Price, Distributions on the Trust Preferred Securities shall cease to accrue on and after the Redemption Date and (iii) the only remaining right of the Holder with respect to the Trust Preferred Securities will be to receive payment of the Redemption Price upon surrender to the Property Trustee.

Pursuant to Section 8.03(b) of the Declaration of Trust, this notice shall be irrevocable.

IMPORTANT TAX INFORMATION

Under current United States federal income tax law, backup withholding, at a rate of 24%, generally may apply to the payment of gross redemption proceeds, unless (i) in the case of a holder that is a beneficial owner of Trust Preferred Securities and that is a United States person (as determined for U.S. federal income tax purposes), the applicable withholding agent has received a properly completed IRS Form W-9 setting forth the holder’s taxpayer identification number, or (ii) the holder otherwise establishes an exemption. A holder that is a beneficial owner of Trust Preferred Securities and that is not a United States person (as determined for U.S. federal income tax purposes) generally may establish an exemption from backup withholding by providing to the applicable withholding agent the applicable IRS Form W-8, upon which it certifies its foreign status. IRS forms may be obtained from the IRS website, www.irs.gov. Holders should consult their tax advisors about these rules and any other reporting obligations that may apply to the ownership or disposition of Trust Preferred Securities.
