4. Transfer and Other Restrictions.

(a) At all times during the period commencing with the execution and delivery of this Agreement and expiring on the Expiration Date, Holder shall not, except in connection with the Merger, Transfer any of the Holder Notes or the Warrants, or enter into an agreement, commitment or other arrangement with respect thereto unless (i) Holder gives prior written notice to the Company of the name of the proposed transferee and (ii) the transferee agrees in writing to be subject to and bound by the terms of this Agreement and a copy of such written agreement is provided to the Company within two Business Days after such Transfer is consummated.

(b) Except as otherwise permitted by this Agreement or by order of a court of competent jurisdiction, Holder will not commit any act or enter into any agreement, commitment or other arrangement that could restrict or affect such Holder’s legal power, authority and right to convert any Holder Notes, to consent to the Merger under the Indenture (including, without limitation, any waivers and amendments thereto) or otherwise prevent or disable Holder from performing any of its obligations under this Agreement.

5. Payments to Holder.

(a) The Company and Holder each hereby agree that (i) the amount of the Conversion Obligation that Holder is entitled to receive under Section 4.5(a)(1) of the Indenture in respect of the conversion of the Holder Notes is an amount in cash for each $1,000 principal amount of the Holder Notes equal to (A) the Common Stock Merger Consideration (as defined in the Merger Agreement) multiplied by (B) the Conversion Rate (as defined in the Indenture) (which product as of the date hereof and based on the Common Stock Merger Consideration being $14.86 in cash per share of Common Stock and the Conversion Rate being 64.6517 shares of Common Stock for each $1,000 principal amount of the Notes, results in an amount of $960.72426 in cash for each $1,000 principal amount of the Holder Notes) (the “Conversion Obligation”), and (ii) the Holder is entitled to receive in cash the Make-Whole Premium as calculated under Section 5.2 of the Indenture in respect of the conversion of the Holder Notes (which as of the date hereof and based on the Common Stock Merger Consideration being $14.86 in cash per share of Common Stock, results in an amount of $144.10782 in cash for each $1,000 principal amount of the Holder Notes). Each of the Conversion Obligation and the Make-Whole Premium are subject to proportional increase or decrease, as the case may be, in the event of any increase or decrease of the Common Stock Merger Consideration.

(b) Notwithstanding Section 5.1(b) of the Indenture, Holder will be entitled to receive any accrued but unpaid interest upon conversion of the Holder Notes except as otherwise set forth in Section 5.1(c) of the Indenture.

(c) In consideration of Holder performing and complying with each of its agreements and obligations set forth in this Agreement, the Company agrees that in addition to the Conversion Obligation and the Make-Whole Premium, that the Company will also pay to Holder, at the

4

same time and place that the Conversion Obligation and Make-Whole Premium are paid, cash in an amount equal to $86.9565 for each $1,000 principal amount of the Holder Notes (the “Consent Premium”), provided, however, that one-third of the Consent Premium shall be paid to Holder within two Business Days after execution of this Agreement and shall be fully earned and non-refundable (the “Consent Consideration”). Holder acknowledges and agrees that it will not be entitled to receive any payments in respect of the Holder Notes in connection with the Proposed Transaction (including without limitation the Conversion Obligation, the Make-Whole Premium and, except as provided in the foregoing proviso, the Consent Premium) unless and until the Supplemental Indenture (as defined below) has been entered into by the Company and the Trustee and the Effective Time occurs. An equivalent amount of Conversion Obligation, Make-Whole Premium and Consent Premium per $1,000 principal amount of outstanding Notes (other than the Holder Notes) will also be offered to all of the other holders of Notes who convert their respective Notes in accordance with the terms and conditions of the Indenture in connection with, and as a result of, the Proposed Transaction.

(d) Upon receipt of all amounts due Holder under this Agreement and conditioned on the occurrence of the Effective Time, Holder agrees that it shall not be entitled to receive any amounts in respect of the Holder Notes (whether in respect of the principal of, or interest on, the Holder Notes or in respect of the Make Whole Premium or otherwise) other than the payments set forth in this Section 5.

(e) Holder understands and acknowledges that Parent, Merger Sub and the Company are entering into the Merger Agreement in reliance upon Holder’s execution and delivery of this Agreement and the agreements, covenants, representations and warranties of Holder contained herein.
