(a)  If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount at maturity of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to the Company, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the Trustee in its exercise of any trust or power.

(b)  The Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its

consequences, including any related payment default that resulted from such acceleration).

(c)  The Indenture provides that if a Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to each Holder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Note, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of Holders. In addition, the Company is required to deliver to the Trustee, within 120 days after the end of each Fiscal Year, an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. The Company is also required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which with the giving of notice or the lapse of time would become an Event of Default, its status and what action the Company is taking or proposes to take with respect thereto (provided that, solely with respect to an Event of Default arising from certain events of bankruptcy or insolvency, no such status or description of action is required).

6.                                      Amendment and Modification.

7.                                      No Impairment of Obligation to Pay or Right to Convert.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Note as provided in the Indenture.

8.                                      Transfer and Exchange.

When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the requirements of the Indenture are met. To permit

registration of transfers and exchanges, the Company will execute and the Trustee will authenticate Notes at the Registrar’s request.

9.                                      No Service Charge.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment by the Holder of a sum sufficient to pay all taxes, assessments or other governmental charges in connection therewith.

10.                               Treatment as Owner.

The registered holder of a Note will be treated as the owner of it for all purposes.

11.                               Payment of Interest.

For Notes in definitive form, interest on such Notes will be payable (i) to holders holding an aggregate principal amount of notes of $1.0 million or less, by check mailed to the holders of those Notes and (ii) to holders holding an aggregate principal amount of notes more than $1.0 million, either by check mailed to each holder or, upon application by a holder to the registrar not later than the relevant record date, by wire transfer in immediately available funds to that holder’s account, which application shall remain in effect until the holder notifies, in writing, the registrar to the contrary.

Each Holder by accepting a Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes.

13.                               Governing Law.

THE INDENTURE AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
