SECTION 2.10.  Outstanding Notes . Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled, those delivered for cancellation and those described in this Section 2.10 as not outstanding.

The Registrar and the Paying Agent shall forward to the Trustee for cancellation any Notes surrendered to them for registration of transfer or exchange or payment.

The Company may not issue new Notes to replace Notes it has redeemed, paid or delivered to the Trustee for cancellation, which shall not prohibit the Company from issuing any Additional Notes, or any Exchange Notes in exchange for Initial Notes.

The Trustee shall provide to the Company a list of all Notes that have been cancelled from time to time as requested in writing by the Company.

The Company may pay the defaulted interest to the Persons who are Noteholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee which specified record date shall not be less than 10 days prior to the payment date for such defaulted interest and shall promptly mail or cause to be mailed to each Noteholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Person entitled to such defaulted interest as provided in this

SECTION 2.14.  CUSIP Numbers, etc . The Company in issuing the Notes may use “CUSIP” or “ISIN” numbers and/or other similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and/or “ISIN” numbers in notices of redemption or exchange as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or exchange and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP numbers and/or other similar numbers.

20

SECTION 2.15.  Issuance of Additional Notes . The Company shall be entitled to issue, from time to time, Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date or the Exchange Notes exchanged therefor (in each case, other than with respect to the date of issuance, issue price and amount of interest payable on the first payment date applicable thereto), as the case may be.

With respect to any Additional Notes, the Company shall set forth in a resolution of the Board of Directors and an Officer’s Certificate, a copy of each shall be delivered to the Trustee, the following information:

In such event, the Company shall provide the Trustee with the information required by this Section 3.3 at least 15 days (or such shorter period as shall be agreed to by the Trustee) prior the date on which notice is required to be sent to Holders. The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder

All money, if any, earned on funds held by the Paying Agent shall be remitted to the Company. In addition, the Paying Agent shall promptly return to the Company any money deposited with the Paying Agent or the Trustee by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest, if any, on, all Notes to be redeemed.

Unless the Company and the Guarantors default in the payment of such redemption price, interest on the Notes or portions of Notes to be redeemed shall cease to accrue on and after the applicable redemption date, subject to the satisfaction of any conditions to such redemption, whether or not such Notes are presented for payment.

the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (and premium, if any) and on any overdue interest, at the rate or rates prescribed therefor in such Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

(b) If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any of the Guarantors and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or the Guarantors.

(b) No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however , that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

Third: To the payment of the balance, if any, to the Company, the Guarantors or any other Person or Persons legally entitled thereto.

SECTION 6.7.  Limitation on Suits . No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the outstanding Notes, considered as one class, it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders), except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

SECTION 6.9.  Restoration of Rights and Remedies . If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any

34

determination in such proceeding, the Company, the Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.10.  Rights and Remedies Cumulative .

The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 6.11.  Delay or Omission Not Waiver . No delay or omission of the Trustee or of any Holder of any Notes to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.

(2) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each outstanding Note affected.

35

Upon any such waiver, such default shall cease to exist and be deemed not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 6.14.  Undertaking for Costs .

SECTION 7.1.  Duties of Trustee .

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

36

conforming to the requirements of this Indenture. However, in the case of any such Officer’s Certificates and Opinions of Counsel which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officer’s Certificates and Opinions of Counsel to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

SECTION 7.4.  Trustee’s Disclaimer . The Trustee shall not be responsible for and makes no representation as to the validity, adequacy or priority of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company or the Guarantors in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.

SECTION 7.5.  Notice of Defaults . If a Default or an Event of Default occurs with respect to the Notes and is continuing and if it is actually known to the Trustee, the Trustee shall mail to each Noteholder notice of the Default within 90 days after it is known to a Trust Officer or written notice of it is received by a Trust Officer of the Trustee. Except in the case of a Default in payment of principal of (and premium, if any) or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of Noteholders.

SECTION 7.6.  Compensation and Indemnity . The Company and each of the Guarantors, severally and jointly, covenant and agree to pay to the Trustee (and any predecessor Trustee) from time to time such compensation for its services as the Company, the Guarantors and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company or one of the Guarantors shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses (including attorneys’ fees and expenses), disbursements and advances incurred or made by it in accordance with the provisions of this Indenture, including costs of collection, in addition to such compensation for its services, except any such expense, disbursement or advance as may arise from its negligence, willful misconduct or bad faith. Such expenses shall include the

39

reasonable compensation and expenses, disbursements and advances of the Trustee’s agents and counsel. The Trustee shall provide the Company and the Guarantors reasonable notice of any material expenditure not in the ordinary course of business. The Company and each of the Guarantors, jointly and severally, shall indemnify each of the Trustee, its officers, directors, employees and any predecessor Trustees against any and all loss, damage, claim, liability or expense (including reasonable attorneys’ fees and expenses) (other than taxes applicable to the Trustee’s compensation hereunder) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee so to notify the Company and the Guarantors shall not relieve the Company and each of the Guarantors of its obligations hereunder, except to the extent that the Company or the Guarantors have been prejudiced by such failure. The Company and the Guarantors shall defend the claim and the Trustee shall cooperate, to the extent reasonable, in the defense of any such claim, and, if (in the opinion of counsel to the Trustee) the facts and/or issues surrounding the claim are reasonably likely to create a conflict with the Company or one of the Guarantors, the Company and the Guarantors shall pay the reasonable fees and expenses of separate counsel to the Trustee. Neither the Company nor the Guarantors need reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith. Neither the Company nor the Guarantors need pay for any settlement made without its consent, which consent shall not be unreasonably withheld or delayed.

To secure the Company’s and the Guarantors’ payment obligations in this Section 7.6, the Trustee (including any predecessor trustee) shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of (and premium, if any) and interest on particular Notes.

The Company’s and the Guarantors’ payment obligations pursuant to this Section 7.6 shall survive the satisfaction, discharge and termination of this Indenture, the resignation or removal of the Trustee and any discharge of this Indenture including any discharge under any bankruptcy law. In addition to and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after the occurrence of a Default specified in Section 6.1(5) or (6) with respect to the Company or the Guarantors, the expenses and the compensation for the services are intended to constitute expenses of administration under bankruptcy law.

SECTION 7.7.  Replacement of Trustee . The Trustee may resign at any time upon 30 days’ written notice to the Company. The Holders of a majority in principal amount of the Notes then outstanding, may remove the Trustee upon 30 days’ written notice to the Trustee and may appoint a successor Trustee, which successor Trustee shall be reasonably acceptable to the Company. The Company shall remove the Trustee if:

(i) the Trustee fails to comply with Section 7.9;

(ii) the Trustee is adjudged bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Trustee or its property; or

40

(iv) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Company shall pay all amounts due and owing to the Trustee under Section 7.6 of the Indenture. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Noteholders affected by such resignation or removal. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.6.

If a successor Trustee does not take office with respect to the Notes within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Notes may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.9, any Noteholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section 7.7, the Company’s and the Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee.

SECTION 7.8.  Successor Trustee by Merger . If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee; provided that such corporation shall be otherwise qualified and eligible under this Article VII and Section 310(a) of the Trust Indenture Act, without the execution or filing of any paper or any further act on the part of the parties hereto.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have.

41

SECTION 7.9.  Eligibility; Disqualification . The Trustee shall at all times satisfy the requirements of Section 310(a) of the Trust Indenture Act. The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the Trust Indenture Act; provided, however , that there shall be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company or the Guarantors are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met.

Nothing herein shall prevent the Trustee from filing with the SEC the application referred to in the second to last paragraph of Section 310(b) of the Trust Indenture Act.

SECTION 7.10.  Reports by Trustee .

(a) The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto. If required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within sixty days after each May 15 following the date of the initial issuance of Notes under this Indenture deliver to Holders a brief report, dated as of such May 15, which complies with the provisions of such Section 313(a). The Trustee also shall comply with Sections 313(b) and 313(c) of the Trust Indenture Act.

(b) A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange, if any, upon which the Notes are listed, with the Commission and with the Company. The Company will promptly notify the Trustee in writing when the Notes are listed on any stock exchange and of any delisting thereof.

SECTION 7.11.  Preferential Collection of Claims Against the Company . The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act.

Guarantees

SECTION 10.1.  Guarantees . Each of the Guarantors hereby fully, unconditionally and irrevocably guarantees to each Holder of the Notes and to the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of (and premium, if any) and interest on the Notes and all other obligations of the Company under this Indenture (all the foregoing being hereinafter collectively called the “ Obligations ”). Each of the Guarantors further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

Each of the Guarantors waives presentation to, demand of payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. Each of the Guarantors waives notice of any default under the Notes or the Obligations. The obligations of each of the Guarantors hereunder shall not be affected by: (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other person under this Indenture, the Notes or any other agreement

48

or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; or (e) any change in the ownership of the Company.

Each of the Guarantors further agrees that the Guarantees herein constitute guarantees of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

The obligations of each of the Guarantors hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each of the Guarantors herein shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of each of the Guarantors or would otherwise operate as a discharge of the Guarantors as a matter of law or equity.

Each of the Guarantors further agrees that the Guarantees herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of (and premium, if any) or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any of the Guarantors by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each of the Guarantors hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law).

Each of the Guarantors further agrees that, as between itself, on the one hand, and the Holders, on the other hand, (i) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of the Guarantees herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (ii) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of these Guarantees.

49

Each of the Guarantors also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 10.1.

SECTION 10.2.  No Subrogation . Notwithstanding any payment or payments made by the Guarantors hereunder, none of the Guarantors shall not be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Company or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any of the Guarantors seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders, by the Company on account of the Obligations are paid in full. If any amount shall be paid to any of the Guarantors on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Obligations.

SECTION 10.3.  Consideration . Each of the Guarantors has received, or shall receive, direct or indirect benefits from the making of the Guarantees.

The Company issued the Notes under an Indenture dated as of December 8, 2009 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “ Indenture ”), among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and, subject to the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “ Trust Indenture Act ”).

The notice of redemption shall specify, among other things, the redemption price and the aggregate principal amount of Notes to be redeemed.

“ Remaining Scheduled Payments ” means, with respect to each Note to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related Redemption Date but for the redemption.

“ Treasury Rate ” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Notes as described in Article III, the Company shall be required to make an offer (the “ Change of Control Offer ”) to each Holder of Notes to repurchase all or, at the Holder’s option, any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in the Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase (the “ Change of Control Payment ”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed to Holders of the Notes describing the transaction or transactions that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “ Change of Control Payment Date ”).

The Change of Control Offer may be accepted for less than the entire principal amount of this Note, but in that event the principal amount of this Note remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the Guarantor and the third party repurchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

At the time the Company delivers Notes to the Trustee which are to be accepted for repurchase, the Company shall also deliver an Officer’s Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms hereof.

Prior to any Change of Control Offer, the Company shall deliver to the Trustee an Officer’s Certificate stating that all conditions precedent contained herein to the right of the Company to make such offer have been complied with.

The Company and the Guarantors shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event.

Unless at least one Rating Agency is providing a rating for the Notes at the commencement of any Trigger Period, the Notes shall be deemed to have ceased to be rated Investment Grade during that Trigger Period.

The registered holder of this Note shall be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years after the date of payment of principal and interest, the Trustee or Paying Agent shall pay the money back to the Company at its request. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

Certain of the Company’s and the Guarantors’ obligations under the Indenture with respect to the Notes may be terminated if the Company or any of the Guarantors irrevocably deposits with the Trustee money or U.S. Government Obligations sufficient to pay and discharge the entire indebtedness on all such Notes, as provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the Company, the Parent Guarantor and the Trustee with the consent of the Holders of more than 50% in principal amount of the Notes at the time outstanding, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that, without the consent of the Holder of each Note affected thereby, no

A-9

such supplemental indenture shall, among other things: (i) reduce the principal amount of outstanding Notes whose Holders must consent to an amendment; (ii) reduce the rate of, change or have the effect of changing the time for payment of interest, including defaulted interest, on the Notes; (iii) reduce the principal of, change or have the effect of changing the fixed maturity of the Notes, or change the date on which the Notes may be subject to redemption or repurchase or reduce the redemption price or repurchase price therefor; (iv) make the Notes payable in currency other than that stated in the Notes or change the place of payment of the Notes from that stated in the Notes or in this Indenture; (v) make any change in provisions of this Indenture protecting the right of each Holder to receive payment of principal of (and premium, if any) and interest on the Notes on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders holding a majority in principal amount of the Notes to waive Defaults or Events of Default; (vi) make any change to or modify in any manner adverse to the Holders the terms and conditions of the obligations of the Guarantors under Article X of the Indenture; (vii) make any change to or modify the ranking of the Notes that would adversely affect the Holders; or (viii) make any change in these amendment and waiver provisions. The Indenture also permits the Company, the Parent Guarantor and the Trustee to enter into one or more supplemental indentures, without the consent of any Holders of the Notes, to, among other things: (i) to cure any ambiguity, defect or inconsistency; (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes; (iii) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act; (iv) to evidence and provide for the acceptance of appointment by a successor Trustee; (v) to conform the terms of this Indenture, the Notes and/or the Guarantees to any provision or other description of the Notes or Guarantees, as the case may be, contained in the Offering Memorandum for the Notes; (vi) to provide for the assumption by a successor corporation, partnership, trust or limited liability company of the Company’s or the Guarantors’ obligations under the Indenture and the Notes, in each case in compliance with the provisions thereof; (vii) to make any change that would provide any additional rights or benefits to the Holders (including to secure the Notes, add guarantees with respect thereto, transfer any property to or with the Trustee, add to the Company’s covenants for the benefit of the Holders, add any additional events of default for the Notes, or surrender any right or power conferred upon the Company or the Guarantors) or that does not adversely affect the legal rights hereunder of any Holder in any material respect; (viii) to provide for the issuance of the Exchange Notes, which shall have terms substantially identical in all material respects to the Initial Notes (except that the transfer restrictions contained in the Initial Notes shall be modified or eliminated, as appropriate, and there will be no registration rights), and which will be treated, together with any outstanding Initial Notes, as a single issue of securities; (ix) to provide for the issuance of any Additional Notes; (x) to comply with the rules of any applicable securities depository; (xi) change or eliminate any restrictions on the payment of principal (or premium, if any) on Notes in registered form; provided that any such action shall not adversely affect the interests of the Holders in any material respect; or (xii) supplement any provision of this Indenture as shall be necessary to permit or facilitate the defeasance and discharge of the Notes in accordance with the Indenture; provided that such action shall not adversely affect the interests of any of the Holders in any material respect.

The Indenture also contains provisions permitting the Holders of not less than a majority in principal amount of the outstanding Notes with respect to which any default under the Indenture shall have occurred and be continuing may, on behalf of the Holders of all Notes, waive such past default under the Indenture and its consequences, except a default (1) in the

A-10

payment of the principal of (or premium, if any) or interest on any Note, or (2) in respect of a covenant or provision hereof which under the Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected.

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes may declare all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency involving the Company or the Parent Guarantor are Events of Default which will result in the Notes being due and payable immediately upon the occurrence of such Events of Default.

Noteholders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives reasonable indemnity. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal (or premium, if any) or interest) if it in good faith determines that withholding notice is not opposed to their interest.

No recourse shall be had for the payment of the principal of or premium, if any, or the interest, if any, on this Note, or for any claim based thereon, or upon any obligation, covenant or agreement of the Company or any of the Guarantors in the Indenture, against any incorporator, limited partner, shareholder, trustee, director, officer or employee, as such, past, present of future, of the Company, of any of the Guarantors or of any successor entity to the Company or any of the Guarantors, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released and waived as a condition of, and as part of the consideration for, the issuance of this Note.

The Company issued the Notes under an Indenture dated as of December 8, 2009 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “ Indenture ”), among the Company, the Guarantors and the Trustee.

If notice has been given as provided in the Indenture and funds for the redemption of this Note or any part thereof called for redemption shall have been made available on the redemption date, this Note or such part thereof shall cease to bear interest on the redemption date referred to in such notice and the only right of the Holder shall be to receive payment of the redemption price. Notice of any optional redemption of any Notes shall be given to the Holder hereof (in accordance with the provisions of the Indenture), not more than 60 nor less than 30 days prior to the redemption date. The notice of redemption shall specify, among other things, the redemption price and the aggregate principal amount of Notes to be redeemed.

“ Remaining Scheduled Payments ” means, with respect to each Note to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related Redemption Date but for the redemption.

If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Notes as described in Article III, the Company shall be required to make an offer (the “ Change of Control Offer ”) to each Holder of Notes to repurchase all or, at the Holder’s option, any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth in the Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase (the “ Change of Control Payment ”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed to Holders of the Notes describing the transaction or transactions that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “ Change of Control Payment Date ”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

The Change of Control Offer may be accepted for less than the entire principal amount of this Note, but in that event the principal amount of this Note remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

B-6

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the Guarantor and the third party repurchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

At the time the Company delivers Notes to the Trustee which are to be accepted for repurchase, the Company shall also deliver an Officer’s Certificate stating that such Notes are to be accepted by the Company pursuant to and in accordance with the terms hereof.

Prior to any Change of Control Offer, the Company shall deliver to the Trustee an Officer’s Certificate stating that all conditions precedent contained herein to the right of the Company to make such offer have been complied with.

The Company and the Guarantors shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company and the Guarantors shall comply with those securities laws and regulations and shall not be deemed to have breached their obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

Unless at least one Rating Agency is providing a rating for the Notes at the commencement of any Trigger Period, the Notes shall be deemed to have ceased to be rated Investment Grade during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event shall be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“ Continuing Directors ” means, as of any date of determination, any member of the Parent Guarantor’s Board of Directors who (1) was a member of the Parent Guarantor’s Board of Directors on the Issue Date; or (2) was nominated for election, elected or appointed to the Parent Guarantor’s Board of Directors with the approval of a majority of the Continuing Directors who were members of the Parent Guarantor’s Board of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval by such directors of the Parent Guarantor’s proxy statement in which such member was named as a nominee for election as a director.)

The Notes are in fully registered form without coupons in denominations of principal amount of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) for a period beginning 15 days before the mailing of a notice of redemption of Notes to be redeemed and ending on the date of such mailing.

The registered holder of this Note shall be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years after the date of payment of principal and interest, the Trustee or Paying Agent shall pay the money back to the Company at its request. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

The Indenture permits, with certain exceptions as therein provided, the Company, the Parent Guarantor and the Trustee with the consent of the Holders of more than 50% in principal amount of the Notes at the time outstanding, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the Notes; provided, however, that, without the consent of the Holder of each Note affected thereby, no such supplemental indenture shall, among other things: (i) reduce the principal amount of outstanding Notes whose Holders must consent to an amendment; (ii) reduce the rate of, change

The Company and the Guarantors shall commence the Exchange Offer by mailing the related Prospectus, appropriate letters of transmittal and other accompanying documents to each Holder stating, in addition to such other disclosures as are required by applicable law, substantially the following:

6

As a condition to participating in the Exchange Offer, a Holder will be required to represent to the Company and the Guarantors that (i) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (ii) at the time of the commencement of the Exchange Offer it has no arrangement or understanding with any Person to participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the provisions of the Securities Act, (iii) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Company or the Guarantors and (iv) if such Holder is a broker-dealer that will receive Exchange Securities for its own account in exchange for Registrable Securities that were acquired as a result of market-making or other trading activities, then such Holder will deliver a Prospectus (or, to the extent permitted by law, make available a Prospectus to purchasers) in connection with any resale of such Exchange Securities.

The Company and the Guarantors shall use their commercially reasonable efforts to complete the Exchange Offer as provided above and shall comply with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff.

7

the Staff, (ii) the Exchange Offer is not for any other reason completed by December 8, 2010 or (iii) upon receipt of a written request (a “Shelf Request”) from any Initial Purchaser representing that it holds Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer, the Company and the Guarantors shall use their commercially reasonable efforts to cause to be filed as soon as practicable after such determination date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf Registration Statement become effective; provided , however , that no Holder (other than an Initial Purchaser) shall be entitled to have Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by the provisions of this Agreement that are applicable to such Holder.

The Company and the Guarantors further agree to supplement or amend the Shelf Registration Statement, the related Prospectus and any Free Writing Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Company or the Guarantors for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder or if reasonably requested by a Holder of Registrable Securities with respect to information relating to such Holder, and to use their commercially reasonable efforts to cause any such amendment to become effective, if required, and such Shelf Registration Statement, Prospectus or Free Writing Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Company and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or filed with the SEC. Such delivery requirement shall not apply with respect to any filing of a report or document under the Exchange Act, at any time following the effective date of the applicable Shelf Registration Statement, when such filing is made to satisfy the Parent Guarantor’s periodic disclosure obligations under Sections 13 and 15 of the Exchange Act.

Each Holder shall pay any underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of such Holder’s Registrable Securities pursuant to the Shelf Registration Statement.

(d) An Exchange Offer Registration Statement pursuant to Section 2(a) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become effective unless it has been declared effective by the SEC or is automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act.

In the event that either the Exchange Offer is not completed or the Shelf Registration Statement, if required pursuant to Section 2(b)(i) or 2(b)(ii) hereof, does not become effective on or prior to December 8, 2010 (the “Target Registration Date”), the interest rate on the Registrable Securities will be increased by 0.50% per annum until the Exchange Offer is completed or the Shelf Registration Statement, if required hereby, becomes effective. In the event that the Company or the Guarantors receive a Shelf Request pursuant to Section 2(b)(iii), and the Shelf Registration Statement required to be filed thereby does not become effective by the later of (x) December 8, 2010 or (y) 90 days after the delivery of such Shelf Request (such later date, the “Shelf Additional Interest Date”), then the interest rate on the Registrable Securities will be increased by 0.50% per annum until the Shelf Registration Statement becomes effective or the Securities become freely tradable under the Securities Act.

If the Shelf Registration Statement, if required hereby, has become effective and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more than 30 days (whether or not consecutive) during the period in which the Shelf Registration Statement is required to be kept effective in accordance with this Agreement, then the interest rate on the Registrable Securities will be increased by 0.50% per annum commencing on the 31 ^st day in such period and ending on such date that the Shelf Registration Statement has again become effective or the Prospectus again becomes usable.

(e) The Company and the Guarantors acknowledge and agree that in the event of any failure by the Company or the Guarantors to comply with their obligations under Section 2(a) and Section 2(b) hereof, the Initial Purchasers or any Holder shall be entitled to specific performance of the obligations of the Company and the Guarantor under Section 2(a) and Section 2(b) hereof as set forth in Section 6(a) hereof.

(vii) use their commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or, in the

11

case of a Shelf Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2), including by promptly filing an amendment to such Shelf Registration Statement on the proper form, and promptly notify each Holder of the withdrawal of any such order or such resolution;

(viii) in the case of a Shelf Registration, if not otherwise available on EDGAR, upon the written request of a Holder of Securities included within the coverage of the Shelf Registration, furnish to each Holder of Registrable Securities, without charge, at least one conformed copy of each Registration Statement and any post-effective amendment thereto (without any documents incorporated therein by reference or exhibits thereto, unless requested);

(x) in the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(a)(vi)(5) hereof, use their commercially reasonable efforts to prepare and file with the SEC a supplement or post-effective amendment to such Shelf Registration Statement or the related Prospectus or any Free Writing Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered (or, to the extent permitted by law, made available) to purchasers of the Registrable Securities, such Prospectus or Free Writing Prospectus, as the case may be, will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Company and the Guarantors shall notify the Holders of Registrable Securities to suspend use of the Prospectus or any Free Writing Prospectus as promptly as practicable after the occurrence of such an event, and such Holders hereby agree to suspend use of the Prospectus or any Free Writing Prospectus, as the case may be, until the Company and the Guarantors have amended or supplemented the Prospectus or the Free Writing Prospectus, as the case may be, to correct such misstatement or omission;

(xi) a reasonable time prior to the filing of any Registration Statement, any Prospectus, any Free Writing Prospectus, any amendment to a Registration Statement or amendment or supplement to a Prospectus or a Free Writing Prospectus or of any document that is to be incorporated by reference into a Registration Statement, a Prospectus or a Free Writing Prospectus after initial filing of a Registration Statement, provide copies of such document to the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement,

12

to the Holders of Registrable Securities and their counsel) and make such of the representatives of the Company and the Guarantors as shall be reasonably requested by the Initial Purchasers or their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities or their counsel) available for discussion of such document; and the Company and the Guarantors shall not, at any time after initial filing of a Registration Statement, use or file any Prospectus, any Free Writing Prospectus, any amendment of or supplement to a Registration Statement or a Prospectus or a Free Writing Prospectus, or any document that is to be incorporated by reference into a Registration Statement, a Prospectus or a Free Writing Prospectus, of which the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities and their counsel) shall not have previously been advised and furnished a copy or to which the Initial Purchasers or their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities or their counsel) shall reasonably object within five Business Days after the receipt thereof. Notwithstanding the foregoing provisions of this Section 3(a)(xi), in the case of any document or report filed by the Parent Guarantor in compliance with its periodic disclosure obligations under Sections 13 and 15 of the Exchange Act, such provisions shall apply to the extent practicable under the circumstances;

(xii) obtain a CUSIP number for all Exchange Securities or Registrable Securities, as the case may be, not later than the initial effective date of a Registration Statement;

(xiv) for a reasonable period prior to the filing of a Shelf Registration and prior to the execution of any underwriting or similar agreement, make available for inspection by counsel of the Holders of the Registrable Securities (an “Inspector”), any Underwriter participating in an Underwritten Offering pursuant to a Shelf Registration Statement, any attorneys and accountants reasonably designated by a majority of the Holders of Registrable Securities to be included in such Shelf Registration and any attorneys and accountants reasonably designated by the Underwriters, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and properties of the Parent Guarantor and its subsidiaries (including, without limitation, the Company and the Subsidiary Guarantor) reasonably requested by any such

13

person, and cause the respective officers, directors and employees of the Company and the Guarantors to supply all information reasonably requested by any such person in connection with a Shelf Registration Statement; provided that, if any such information is identified by the Company or the Guarantors as being confidential or proprietary, each Person receiving such information shall take such actions as are reasonably necessary to protect the confidentiality of such information to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of any Inspector, Holder or Underwriter, and the Company and the Guarantors shall be entitled to reasonably request that such persons sign a confidentiality agreement covering the receipt of such information;

(xv) if reasonably requested by any Holder of Registrable Securities covered by a Shelf Registration Statement, promptly include in a Prospectus supplement or post-effective amendment such information with respect to such Holder as such Holder reasonably requests in writing to be included therein and make all required filings of such Prospectus supplement or such post-effective amendment as soon as the Company has received notification of the matters to be so included in such filing; and

(xvi) in the case of a Shelf Registration, enter into such customary agreements and take all such other commercially reasonable actions in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities covered by the Shelf Registration Statement) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such connection, (1) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Registrable Securities with respect to the business of the Company and its subsidiaries and the Registration Statement, Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and confirm the same if and when requested, (2) obtain opinions of counsel to the Company and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters and their respective counsel) addressed to each selling Holder and Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings, (3) obtain “comfort” letters from the independent registered public accounting firm of the Company and the Guarantors (and, if necessary, any other independent registered public accounting firm of any subsidiary of the Company or the Guarantors, or of any business acquired by the Company or the Guarantors for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling Holder (to the extent permitted by applicable professional standards) and Underwriter of Registrable Securities, such letters to be in customary form and covering matters

14

of the type customarily covered in “comfort” letters in connection with shelf registrations, and (4) deliver such documents and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable Securities being sold or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued validity of the representations and warranties of the Company and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement.

(b) In the case of a Shelf Registration Statement, the Company may require each Holder of Registrable Securities to furnish to the Company such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Company and the Guarantors may from time to time reasonably request in writing. The Company shall be entitled, in its reasonable discretion, to exclude from such Shelf Registration Statement the Registrable Securities of any Holder who fails to furnish such information within a reasonable time (not to exceed 15 Business Days) after receiving such request.

(c) In the case of a Shelf Registration Statement, each Holder of Registrable Securities covered in such Shelf Registration Statement agrees that, upon receipt of any notice from the Company and the Guarantors of the happening of any event of the kind described in Section 3(a)(vi)(3) or 3(a)(vi)(5) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus and any Free Writing Prospectus contemplated by Section 3(a)(x) hereof and, if so directed by the Company and the Guarantors, such Holder will deliver to the Company and the Guarantors all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus and any Free Writing Prospectus covering such Registrable Securities that is current at the time of receipt of such notice.

(d) If the Company and the Guarantors shall give any notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Company and the Guarantors shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders of such Registrable Securities shall have received copies of the supplemented or amended Prospectus or any Free Writing Prospectus necessary to resume such dispositions. The Company and the Guarantors may give any such notice only twice during any 365-day period and any such suspensions shall not exceed 45 days for each suspension and there shall not be more than two suspensions in effect during any 365-day period. The Initial Purchasers, the Holders and any Participating Broker-Dealers shall keep confidential the cause of such notice for so long as such cause is not otherwise publicly known.

15

(e) The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a majority in principal amount of the Registrable Securities included in such offering and shall be reasonably acceptable to the Company.

No person may participate in any such Underwritten Offering unless such person completes and executes all questionnaires, powers of attorney, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

Notwithstanding anything to the contrary contained herein, (i) the Company and the Guarantors shall not be required to cooperate with any Underwritten Offering unless a request for the Underwritten Offering is made by Holders of at least 25% of the aggregate principal amount of Securities covered by a Shelf Registration Statement; (ii) the Company and the Guarantors shall not be obligated to cooperate with more than two Underwritten Offerings pursuant to this Agreement; and (iii) upon receipt of a request to prepare and file an amendment or supplement to a Shelf Registration Statement or prospectus in connection with any Underwritten Offering, the Company and the Guarantors may delay the filing of any such amendment or supplement as specified in Section 3(d) hereof; provided , however , that nothing in this clause (iii) shall limit the obligations of the Company and the Guarantors under Section 2.

4. Participation of Broker-Dealers in Exchange Offer . (a) The Staff has taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a “Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Securities.

The Company and the Guarantors understand that it is the Staff’s position that if the Prospectus contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers (or, to the extent permitted by law, made available to purchasers) to satisfy their prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities for

16

their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act.

(b) In light of the above, and notwithstanding the other provisions of this Agreement, the Company and the Guarantors agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 135 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d) of this Agreement, if requested by the Initial Purchasers or by one or more Participating Broker-Dealers), in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Company and the Guarantors further agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period in connection with the resales contemplated by this Section 4.

(c) The Initial Purchasers shall have no liability to the Company, the Guarantors or any Holder with respect to any request that they may make pursuant to Section 4(b) above.

5. Indemnification and Contribution . (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser and each Holder, their respective affiliates, directors and officers and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a material fact contained in any Prospectus, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser or information relating to any Holder furnished to the Company in writing through Banc of America and J.P. Morgan or any selling Holder, respectively, expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Company and the Guarantors, jointly and severally, will also indemnify the

17

Underwriters, if any, selling brokers, dealers and similar securities industry professionals participating in the distribution, their respective affiliates and each Person who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantors, the Initial Purchasers and the other selling Holders, their respective affiliates, the directors of the Company and the Guarantors, each officer of the Company and the Guarantors who signed the Registration Statement and each Person, if any, who controls the Company, the Guarantors, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in Section 5(a) above, but only with respect to any losses, claims, damages or liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Holder furnished to the Company in writing by such Holder expressly for use in any Registration Statement, any Prospectus and any Free Writing Prospectus.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any Person in respect of which indemnification may be sought pursuant to either Section 5(a) or 5(b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 5 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided , further , that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 5. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such

18

counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for any Initial Purchaser, its affiliates, directors and officers and any control Persons of such Initial Purchaser shall be designated in writing jointly by Banc of America and J.P. Morgan, (y) for any Holder, its directors and officers and any control Persons of such Holder shall be designated in writing by the Majority Holders and (z) in all other cases shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) If the indemnification provided for in Section 5(a) and 5(b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person

19

under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors from the offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Holders on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Guarantors on the one hand and the Holders on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company, the Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 5(d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in Section (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 5 are several and not joint.

(f) The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any

20

termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any Holder, their respective affiliates or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Company or the Guarantors or the officers or directors of or any Person controlling the Company or the Guarantors, (iii) acceptance of any of the Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement.

6. General .

(a) Specific Performance. The Company and the Guarantors acknowledge that there would be no adequate remedy at law if the Company or the Guarantors failed to perform any of their obligations in this Agreement (including, without limitation, their obligations under Section 2(a) and Section 2(b) hereof) and that any such failure may result in material irreparable injuries to the Initial Purchasers and the Holders from time to time of the Registrable Notes and that it will not be possible to measure damages for such injuries precisely, and, accordingly the Company and the Guarantors agree that the Initial Purchasers and such Holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Company and the Guarantors under this Agreement in accordance with the terms and conditions of this Agreement, in any U.S. federal or New York court located in the Borough of Manhattan, The City of New York.

(b) No Inconsistent Agreements. The Company and the Guarantors represent, warrant and agree that (i) the rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of any other outstanding securities issued or guaranteed by the Company or the Guarantors under any other agreement and (ii) none of the Company or the Guarantors has entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof.

(c) Amendments and Waivers.

If any transferee of any Holder shall acquire Registrable Securities in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof.

Each Holder shall be a third party beneficiary to the agreements made hereunder between the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder.

(i) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

This Agreement contains the entire agreement between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. The Company, the Guarantors and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, void or unenforceable provisions.
