In the event that such notice of optional prepayment contains such a condition and such money is not so received, the prepayment shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of optional prepayment was given, that such money was not so received and such prepayment was not required to be made, and the Company shall promptly return to the Purchasers of the Notes to have been redeemed any of such Notes which had been surrendered for payment upon such redemption.

Section 9.3 Allocation of Partial Prepayments. In the case of each partial prepayment of a series of Notes pursuant to Section 9.2, the principal amount of the Notes of such series to be prepaid shall be allocated among all of the Notes of such series at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

Section 9.4 Maturity; Surrender, Etc. In the case of each optional prepayment of Notes of any series pursuant to this Section 9, the principal amount of each Note to be prepaid shall, subject to the satisfaction of the conditions to such prepayment, mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any from and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 9.5 Purchasers of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions (except to the extent necessary to reflect differences in interest rates and maturities of the Notes of different series). Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 25% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 5 Business Days from its receipt of such notice to accept such offer.

Section 9.6 Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 9.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such Maturity Date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

Section 9.7 Make-Whole Amount.

“Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 9.2.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor

22

publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 9.4.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 9.2.

Section 9.8 Change in Control / Sanctions Event.

(a) Notice of Change in Control. The Company will, within five (5) days after the occurrence of any Change in Control or Sanctions Event, give written notice (the “Change in Control Notice”) of such Change in Control or Sanctions Event to each holder of Notes. Such Change in Control Notice shall contain and constitute an offer to prepay the Notes as described in Section 9.8(b) hereof and shall be accompanied by the certificate described in Section 9.8(e).

(b) Offer to Prepay Notes. The offer to prepay Notes shall be an offer to prepay, in accordance with and subject to this Section 9.8, all, but not less than all, the Notes held by each holder on a date specified in such offer (the “Proposed Prepayment Date”). Such Proposed Prepayment Date shall be not less than 15 days and not more than 30 days after the date of such offer.

(c) Acceptance/Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 9.8 by causing a notice of such acceptance to be delivered to the Company not later than 15 days after receipt by such holder of the most recent offer of prepayment. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 9.8 shall be deemed to constitute a rejection of such offer by such holder.

23

(d) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 9.8 shall be at 100% of the principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment, but without Make-Whole Amount or other premium unless a Sanctions Event has occurred, in which case the Make Whole Amount shall be due and payable in connection with such prepayment. The prepayment shall be made on the Proposed Prepayment Date.

(e) Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 9.8 shall be accompanied by a certificate, executed by a Senior Financial Officer and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 9.8; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 9.8 have been fulfilled; and (vi) in reasonable detail, the nature and date or proposed date of the Change in Control.

Section 9.9 Prepayment in Connection with Sales of Assets. (a) If the Company wants to offer to prepay any series of Notes in connection with an Asset Disposition pursuant to Section 8.20, the Company will give written notice thereof to the holders of all outstanding Notes of such series, which notice shall (i) refer specifically to Section 9.9 and describe in reasonable detail the Asset Disposition giving rise to such offer to prepay the Notes, (ii) specify the principal amount of each Note being offered to be prepaid, (iii) specify a date not less than 30 days and not more than 60 days after the date of such notice (the “Disposition Prepayment Date”) and specify the Disposition Response Date (as defined below), and (iv) offer to prepay on the Disposition Prepayment Date the amount specified in (ii) above with respect to each Note together with interest accrued thereon to the Disposition Prepayment Date. Each Noteholder shall notify the Company of such Noteholder’s acceptance or rejection of such offer by giving written notice of such acceptance or rejection to the Company (provided, however, that any Noteholder who fails to so notify the Company shall be deemed to have rejected such offer) on a date at least 5 days prior to the Disposition Prepayment Date (such date 5 days prior to the Disposition Prepayment Date being the “Disposition Response Date”), and the Company shall prepay on the Disposition Prepayment Date the amount specified in (ii) above plus interest accrued thereon to the Disposition Prepayment Date, but without Make-Whole Amount or other premium, with respect to each Note of such series held by the Noteholders who have accepted such offer in accordance with this Section 9.9.

(b) Notwithstanding anything contained in this Section 9.9 to the contrary, if and so long as any Default or Event of Default shall have occurred and be continuing, any partial prepayment of the Notes pursuant to the provisions of Section 9.9(a) shall be allocated among all of the Notes of all series of Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof.

Section 10. Events of Default.

Section 11. Remedies On Default, Etc.

Section 11.1 Acceleration.

(a) If an Event of Default with respect to the Company described in Section 10(e) or (f) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any other Event of Default has occurred and is continuing, the Required Holders may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c) If any Event of Default described in Section 10(a) or (b) has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

(d) Upon any Notes becoming due and payable under this Section 11.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including interest accrued at the Default Rate) and (y) the Make-Whole Amount determined in respect of such principal amount shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances and does not constitute payment of unaccrued future interest.

Section 11.2 Other Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 11.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

27

Section 11.3 Rescission. At any time after any Notes have been declared due and payable pursuant to Section 11.1(b) or Section 11.1(c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of any Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 16, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 11.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

Section 11.4 No Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 14, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 11, including reasonable attorneys’ fees, expenses and disbursements.

28

the Company’s expense (except as provided below), one or more new Notes of the same series (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Schedule 1(a), Schedule 1(b) or Schedule 1(c), as applicable. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon.

Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 7.1. The transferee of any Note in accordance with Section 12.1 shall have all rights, benefits and obligations of the holders of such Note under the Note Documents as if such holder were an original signatory hereto without any further action being required under the Note Documents.

Section 12.3 Replacement of Notes. Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 17(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(b) in the case of mutilation, upon surrender and cancellation thereof, within ten Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

The Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, interest and all other amounts becoming due hereunder by the method and at the address specified for such purpose below such Purchaser’s name in Schedule B, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably

29

promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 12.2. The Company will afford the benefits of this Section 13.2 to any Institutional Investor that is the direct or indirect transferee in accordance with Section 12.1 of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 13.2.
