Debenture in exchange for such Debenture a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Debenture, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Debenture held by such holder and having similar ranking to the Debenture, and satisfactory to the Required Holders and (ii) unless the Fundamental Transaction would result in a Change of Control and the Company complies with the provisions of Section 4(b), the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market (a “Public Successor Entity”). Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Debenture referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Debenture with the same effect as if such Successor Entity had been named as the Company herein. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the redemption of this Debenture.

               (b) Redemption Right. No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”). At any time during the period beginning after the Holder’s receipt of a Change of Control Notice and ending on the date of the consummation of such Change of Control (or, in the event a Change of Control Notice is not delivered at least ten (10) days prior to a Change of Control, at any time on or after the date which is ten (10) days prior to a Change of Control and ending ten (10) days after the consummation of such Change of Control), the Required Holders may require the Company to redeem all or any portion of the Debenture by delivering written notice thereof (“Change of Control Redemption Notice”) to the Company, which Change of Control Redemption Notice shall indicate the portion of the Debenture each Holder is electing to redeem. The portion of this Debenture subject to redemption pursuant to this Section 4 shall be redeemed by the Company at a price equal to the sum of the amount being redeemed together with accrued and unpaid Interest with respect to such amount and accrued and unpaid Late Charges with respect to such amount and Interest (the “Change of Control Redemption Price”).

          (5) COMPANY REDEMPTION. Prior to the Maturity Date, the Company may elect to pay to the Holder of this Debenture the Company Redemption Amount, subject to and in accordance with the terms of this Section 5, by redeeming the Principal, in whole or in part, in accordance with this Section 5 (a “Company Redemption”). On or prior to the date which is the sixth (6th) Trading Day prior to the Company Redemption (each, a “Company Redemption Notice Due Date”), the Company shall deliver written notice (each, a “Company Redemption Notice”), to the Holder which Company Redemption Notice shall state the amount of Principal which the Company elects to redeem pursuant to a Company Redemption (the “Company Redemption Amount”), together with accrued and unpaid Interest with respect to such Company Redemption Amount and accrued and unpaid Late Charges with respect to such Company Redemption Amount and Interest. Each Company Redemption Notice shall be

irrevocable. The Company shall redeem the applicable Company Redemption Amount of this Debenture pursuant to this Section 5 together with the corresponding Company Redemption Amounts of the Other Debentures pursuant to the corresponding provisions of the Other Debentures. If the Company elects a Company Redemption, then the Company Redemption Amount which is to be paid to the Holder on the applicable Company Redemption Date shall be redeemed by the Company on such Company Redemption Date, and the Company shall pay to the Holder on such Company Redemption Date, by wire transfer of immediately available funds, an amount in cash equal to the Company Redemption Amount.

          (6) NONCIRCUMVENTION. The Company and Parent hereby covenant and agree that neither the Company nor Parent will, by amendment of its Articles or Certificate (as applicable) of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Debenture, and will at all times in good faith carry out all of the provisions of this Debenture and take all action as may be required to protect the rights of the Holder of this Debenture.

          (7) HOLDER’S REDEMPTIONS.

               (a) Mechanics. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within five Business Days after the Company’s receipt of the Required Holders’ Event of Default Redemption Notice. If the Required Holders have submitted a Change of Control Redemption Notice in accordance with Section 4(b), the Company shall deliver the applicable Change of Control Redemption Price to the Holder concurrently with the consummation of such Change of Control if such notice is received prior to the consummation of such Change of Control (provided, that if the Change of Control is described in Section 1(c)), then the payment shall be made in accordance with Section 1(c) and within five (5) Business Days after the Company’s receipt of such notice otherwise. In the event of a redemption of less than all of the Principal of this Debenture, the Company shall promptly cause to be issued and delivered to the Holder a new Debenture (in accordance with Section 12(d)) representing the outstanding Principal which has not been redeemed.

               (b) Redemption by Other Holders. Any Event of Default Redemption Notice or Change of Control Redemption Notice for redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section 3(b), Section 4(b) or Section 8 is to be delivered to the Company by the Required Holders. If the Company receives any Event of Default Redemption Notice or Change of Control Redemption Notice and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice, then the Company shall redeem a pro rata amount from each holder of the Debentures (including the Holder) based on the principal amount of the Debentures submitted for redemption pursuant to such Event of Default Redemption Notice or Change of Control Redemption Notice received by the Company from the Required Holders.
