Expiration Date

The Expiration Date is 5:00 p.m., New York City time, on Friday, June 29, 2007, unless extended.

INTEREST RATE ADJUSTMENT

The section of the Amended and Restated Consent Solicitation Statement titled “Interest Rate Adjustment” is hereby amended by deleting the following paragraph:

“Notwithstanding the foregoing, if at any time there is only one Rating Agency providing a rating of the Notes then any subsequent increase or decrease required by a change in the rating by the Rating Agency continuing to provide a rating shall be twice the percentage set forth above subject to the limitations set forth above. The failure of either Rating Agency to provide a rating of the Notes shall not result in an adjustment hereunder.”

and replacing such deleted language with the following paragraph:

“Notwithstanding the foregoing, if at any time there is only one Rating Agency providing a rating of the Notes then any subsequent increase or decrease required by a change in the rating by the Rating Agency continuing to provide a rating shall be twice the percentage set forth above subject to the limitations set forth above. The failure of either Rating Agency (but not both) to provide a rating of the Notes shall not result in an adjustment hereunder. If both Rating Agencies cease to provide a rating, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% above the Current Interest Rate.”
