sufficient in the judgment of both the Company and the Trustee, to protect the Company, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note, including reasonable fees and expenses of its counsel and of the Trustee and its counsel. In case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. Every replacement Note shall constitute an additional obligation of the Company, entitled to the benefits of this Indenture, subject to Section 2.08 .

Section 2.08. Outstanding Notes . Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Subject to the provisions of Section 2.09 , a Note does not cease to be outstanding because the Company or any of its Affiliates holds the Note.

If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07 .

If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal and interest due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

Section 2.09. Treasury Notes; When Notes Are Disregarded . In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Company or any of its Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or of such other obligor.

Section 2.10. Temporary Notes . Until definitive Notes are ready for delivery, the Company may prepare and execute and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Company in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate upon receipt of a written order of the Company pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes shall be entitled to the same benefits under this Indenture as definitive Notes.

Section 2.11. Cancellation . The Company at any time may deliver Notes previously authenticated hereunder which the Company has acquired in any lawful manner, to the Trustee for cancellation. The Registrar, Conversion Agent and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange, payment or conversion. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel all Notes surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07 , the Company may not issue new

-34-

Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11 . The Trustee shall dispose of all cancelled Notes in accordance with the Trustee’s customary procedures.

Section 2.12. CUSIP Numbers . A “ CUSIP ” number shall be printed on the Notes, and the Trustee shall use the CUSIP number in notices of redemption, purchase or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee of any change in the CUSIP number.

Section 2.13. Issuance of PIK Notes .

Conversion

Section 4.01. Conversion Right and Conversion Rate .

(a) Subject to and upon compliance with the provisions of this Article Four , at the option of the Holder thereof, any portion of the principal amount of any Note that is an integral multiple of $1,000 may be converted into fully paid and non-assessable shares of Common Stock at the Conversion Rate, determined as hereinafter provided, in effect at the time of conversion. The Holders may surrender Notes for conversion at the applicable Conversion Rate at any time after the Original Issue Date until the close of business on the Business Day immediately preceding the final maturity date of the Notes.

(b) All calculations under this Article Four shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be.

Section 4.02. Conversion Consideration .

(a) Upon surrendering any Notes for conversion, the Holder of such Notes shall receive, in respect of each $1,000 principal amount of Notes, shares of Common Stock at an initial conversion rate of 1,389.00 shares per $1,000 principal amount of Notes (the “ Conversion Rate ”), which is based upon an initial Conversion Price of $0.72 per share. The Conversion Rate (and Conversion Price) are subject to adjustment as provided in Section 4.05 .

(b) The Holders at the close of business on a Record Date will be entitled to receive the interest payment on those Notes on the corresponding Interest Payment Date notwithstanding the conversion of such Notes following that Record Date or the Company’s default in payment of the interest due on that Interest Payment Date. However, Notes surrendered for conversion during the period between the close of business on any Record Date and the close of business on the Business Day immediately preceding the applicable Interest Payment Date must be accompanied by payment of an amount equal to the interest payable on such Notes on that Interest Payment Date.

Notwithstanding the foregoing, if Notes are converted during the period between the close of business on any Record Date and the opening of business on the corresponding Interest Payment Date and the Company has specified a Change of Control Payment Date (as defined below) during such period or on such corresponding Interest Payment Date pursuant to the Change of Control redemption provisions described in Section 5.15 , the Holder who tenders such Notes for conversion shall receive the interest payable on such Interest Payment Date and need not include payment of the amount of such interest upon surrender of its Notes for conversion.

Except as provided above with respect to a voluntary conversion, the Company shall make no payment or allowance for unpaid interest, whether or not in arrears, on converted Notes or for dividends on the shares of Common Stock issued upon conversion.
