Supplemental Indenture modifying the Indenture
to provide that, on and after the effective date of the Merger, the consideration due upon conversion of each $1,000 principal
amount of Notes shall be solely cash in an amount equal to the Conversion Rate (as may be increased pursuant to Section 10.07 of
the Indenture, as discussed below), multiplied by the consideration per share of Common Stock in the Merger, $14.00 per share.
While the Notes are not currently convertible,
if the Merger is completed, the Notes will become convertible from and after the effective date of the Merger until the date specified
in the Notice of Fundamental Change, Make-Whole Fundamental Change, Right to Convert and Supplemental Indenture to be provided
to the holders of the Notes following the completion of the Merger. The Conversion Rate in effect on the date of this Notice is
70.2790 shares of Common Stock per $1,000 principal amount of Notes, which equates to a Conversion Price of approximately $14.23
per share. The Merger, if completed, will constitute a Make-Whole Fundamental Change under the Indenture and, in accordance with
Section 10.07 of the Indenture, the Conversion Rate for conversions in connection with a Make-Whole Fundamental Change as described
in the Indenture will be increased by an amount determined by reference to the table in Section 10.07(d) of the Indenture. If the
Merger is not completed, no Make-Whole Fundamental Change will occur and the Notes will not become convertible.
In the event of any conflicting information
in this Notice and in the Indenture, the information in the Indenture will control. Noteholders should not assume that the information
in this Notice is accurate as of any date other than the date hereof.
