Section 6.02. Acceleration.

          (a) If any Event of Default (other than an Event of Default specified in clause (i) or (j) of Section 6.01 hereof) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes, by written notice to the Company (and, if such notice is given by such Holders, to the Trustee), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest on the Notes to be due and payable immediately. Upon such declaration of acceleration, such principal of, premium, if any, and accrued and unpaid interest and Liquidated Damages, if any, shall be immediately due and payable.

          (b) Notwithstanding the foregoing, if an Event of Default specified in clause (i) or (j) of Section 6.01 hereof occurs with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, the principal of, premium, if any, and accrued and unpaid interest and Liquidated Damages, if any, on the Notes then outstanding shall be due and payable immediately without further action or notice on the part of the Trustee or any Holder.

Section 6.03. Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

          The Trustee may maintain a proceeding to enforce its rights and to pursue its remedies under the Notes and this Indenture even if the Trustee does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults.

          At any time after declaration of acceleration, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, the Holders of at least a majority in principal amount of the outstanding Notes by written notice to the Company and to the Trustee, may waive all past Defaults, except a Default in the payment of principal of, premium, if any, or interest on any Note as specified in clause (a) or (b) of Section 6.01 or in respect of a covenant or provision of this Indenture which cannot be modified or amended without the consent of the Holder of each outstanding Note affected, and rescind and annul a declaration of acceleration and its consequences if:

     (a) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived; and

     (b) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

          Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

Section 6.05. Control by Majority.

          Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for enforcing any rights and exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may involve the Trustee in personal liability or that the Trustee determines in good faith may be unduly prejudicial to the rights of other Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received for Holders of Notes.

Section 6.06. Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if:

     (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default;

     (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

     (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

     (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

          A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07. Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Liquidated Damages, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08. Collection Suit by Trustee.

          If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount of principal of, premium and Liquidated Damages, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and 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.

Section 6.09. Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, and to secure the payment of same, the Trustee is hereby granted an interest security in, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained 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, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities.

          If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under Sections 6.09 and 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee, its agents or attorneys and the costs and expenses of collection;

     Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Liquidated Damages, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Liquidated Damages, if any and interest, respectively; and

     Third: to the Company or to such party as a court of competent jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and disbursements against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.06 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

Section 6.12. 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 determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company, Trustee and the Holders shall continue as though no such proceeding had been instituted, except that the rights of the Trustee to receive compensation, reimbursement of any of its expenses or indemnification from the Holders in connection with such proceeding in accordance with the terms of this Indenture or any separate agreement or understanding between the Trustees and the Holders shall not be affected by this Section 6.12.

Section 6.13. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. 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 6.14. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder 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. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 7.06. Reports by Trustee to Holders of the Notes.

          Within 60 days after each January 15 beginning with January 15, 2006, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).

          A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the Commission and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange.

Section 7.07. Compensation and Indemnity.

          The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as shall be agreed upon in writing by the Company and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a Trustee of an express trust.

-60-

liability or expense or a portion thereof may be attributable to the Trustee’s negligence or bad faith. An Indemnitee shall notify the Company promptly of any claim for which that Indemnitee may seek indemnity. Failure by the Indemnitee to so notify the Company shall not relieve the Company of its obligations hereunder. Subject to receipt of the consent of the party to be defended, which consent shall not be unreasonable withheld or delayed, the Company shall defend the claim and the Trustee shall cooperate in the defense. The Indemnitees may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld or delayed. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an Indemnitee through that Indemnitee’s own willful misconduct, negligence or bad faith.

          The obligations of the Company under this Section 7.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture.

          To secure the Company’s payment obligations in this Section, the Trustee shall have a Lien and is hereby granted a security interest prior in right of payment prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the fees, disbursements and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

          The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

Section 7.08. Replacement of Trustee.

          A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

          The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing.

Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

          If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

          If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. 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 Holders of the Notes. Subject to the Lien provided for in Section 7.07 hereof, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided, however, that all sums owing to the retiring Trustee hereunder shall have been paid and the property so transferred shall remain subject to the Lien provided for in Section 7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, etc.

          If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking corporation, the successor corporation or national banking corporation without any further act shall be the successor Trustee.

Section 7.10. Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate Trustee power, that is subject to supervision or examination by federal or state authorities, and that has (or the bank holding company of which it is an Affiliate has) a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition.

          This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusions set forth in TIA § 310(b)(1) are met.

Section 7.11. Preferential Collection of Claims Against Company.

          The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein.

Each Guarantor further, to the extent permitted by law, waives and relinquishes all claims, rights and remedies accorded by applicable law to guarantors and agrees not to assert or take advantage of any such claims, rights or remedies, including but not limited to: (i) any right to require any of the Trustee, the Holders or the Company (each, a “Benefited Party”), as a condition of payment or performance by such Guarantor, to (A) proceed against the Company, any other guarantor (including any other Guarantor) of the obligations under the Subsidiary Guarantees or any other person, (B) proceed against or exhaust any security held from the Company, any such other guarantor or any other person, (C) proceed against or have resort to any balance of any deposit account or credit on the books of any Benefited Party in favor of the Company or any other person, or (D) pursue any other remedy in the power of any Benefited Party whatsoever; (ii) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Company including any defense based on or arising out of the lack of validity or the unenforceability of the obligations under the Subsidiary Guarantees or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Company from any cause other than payment in full of the obligations under the Subsidiary Guarantees; (iii) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (iv) any defense based upon any Benefited Party’s errors or omissions in the administration of the obligations under the Subsidiary Guarantees, except behavior which amounts to bad faith; (v)(A) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of the Subsidiary Guarantees and any legal or equitable discharge of such Guarantor’s obligations hereunder, (B) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (C) any rights to set-offs, recoupments and counterclaims and (D) promptness, diligence and any requirement that any Benefited Party protect, secure, perfect or insure any security interest or lien or any

-63-

property subject thereto; (vi) notices, demands, presentations, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance of the Subsidiary Guarantees, notices of default under the Notes or any agreement or instrument related thereto, notices of any renewal, extension or modification of the obligations under the Subsidiary Guarantees or any agreement related thereto, and notices of any extension of credit to the Company and any right to consent to any thereof; (vii) to the extent permitted under applicable law, the benefits of any “One Action” rule and (viii) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms of the Subsidiary Guarantees. Except as set forth in Section 8.05, each Guarantor hereby covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in its Guarantee and this Indenture.

          (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, any Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

          (d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 6.02 hereof for the purposes of any Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of such obligations as provided in Section 6.02 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of any such Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the applicable Subsidiary Guarantee.

Section 8.02. Additional Guarantees.

          If any Restricted Subsidiary becomes obligated pursuant to Section 4.12 hereof, then the Company shall cause any such Restricted Subsidiary to, within ten Business Days of the date on which any such Restricted Subsidiary became so obligated, (a) execute and deliver to the Trustee a Supplemental Indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee, on a senior unsecured basis, all of the Company’s obligations under the Notes and this Indenture on the terms set forth herein and therein and (b) deliver to the Trustee an Opinion of Counsel that, subject to customary assumptions and exclusions, such supplemental indenture has been duly executed and delivered by such Restricted Subsidiary. Any Restricted Subsidiary that becomes a Guarantor shall remain a Guarantor unless (i) designated an Unrestricted Subsidiary by the Company in accordance with this Indenture; (ii) is otherwise released from its obligations as a Guarantor pursuant to Section 8.05 hereof; or (iii) the circumstances giving rise to the obligation to provide a guarantee under Section 4.12 no longer exist.

Section 8.03. Limitation on Guarantor Liability.

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under this Article 8 shall be limited to the

-64-

maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 8, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 8.04. Merger and Consolidation of Guarantors.

          Except as otherwise provided in Section 8.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving person) another person, other than the Company or another Guarantor unless:

     (a) immediately after giving effect to such transaction, no Default or Event of Default exists; and

     (b) either (i) the person acquiring the property in any such sale or disposition or the person formed by or surviving any such consolidation or merger, assumes all the obligations of that Guarantor under this Indenture and the Subsidiary Guarantee of such Guarantor pursuant to a supplemental indenture reasonably satisfactory to the Trustee, or (ii) in the case of a sale or other disposition of all or substantially all of the assets of such Guarantor’s assets, the Net Proceeds of such sale of other disposition are applied in accordance with Section 4.15.

          In case of any such sale or other disposition, consolidation, merger, sale or conveyance and upon the assumption by the successor person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor person thereupon may cause to be signed any or all of the Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

          Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) of this Section 8.04, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into an Company or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to an Company or another Guarantor.

Section 8.05. Release.

          (a) In the event of (i) a sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all to the Capital Stock of any Guarantor, in each case to a person that is not (either before or after giving effect to such transactions) a Subsidiary of the Company, so long as the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation Section 4.15 hereof, or (ii) a designation by the Company of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with Section 4.13, such Guarantor or, in the case of a

-65-

sale or other disposition of all or substantially all of the assets of such Guarantor, the corporation acquiring such property, will be released and relieved of any obligations under its Subsidiary Guarantee.

          (b) Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 4.07 hereof, or such designation was made in accordance with Section 4.13 hereof, as the case may be, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee.

          (c) Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 8.

ARTICLE 9.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 9.01. Option to Effect Legal Defeasance or Covenant Defeasance.

          The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 9.02 or 9.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 9.

Section 9.02. Legal Defeasance and Discharge.

          Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 9.05 hereof and the other Sections of this Indenture referred to in clauses (a) through (d) below, and to have satisfied all their other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

     (a) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due;

     (b) the Company’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments;

     (c) the rights, powers, trust, duties and immunities of the Trustee and the Company’s obligations in connection therewith; and

     (d) the Legal Defeasance provisions of this Article 9.

          Subject to compliance with this Article 9, the Company may exercise its option under this Section 9.02, notwithstanding the prior exercise of its option under Section 9.03 hereof.

Section 9.03. Covenant Defeasance.

          Upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from its obligations under the covenants contained in Sections 4.07 through 4.13 and 4.15 through 4.20 hereof, both inclusive, and Section 5.01(a)(iv) with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document, and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 9.01 hereof of the option applicable to this Section 9.03, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, Sections 6.01(e), 6.01(g) and 6.01(i) hereof shall not constitute Events of Default.

Section 9.04. Conditions to Legal or Covenant Defeasance.

          The following are the conditions precedent to the application of either Section 9.02 or 9.03 hereof to the outstanding Notes:

          In order to exercise either Legal Defeasance or Covenant Defeasance:

     (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants selected by the Company, to pay the principal of, and premium, if any, and interest on, the Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

     (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that:

     (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

     (b) since the date of this Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same

manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

     (3) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

     (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings);

     (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under this Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

     (6) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

     (7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and

     (8) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, assuming no intervening bankruptcy of the Company between the date of deposit and the 91st day following the date of deposit and that no Holder is an insider of the Company, after the 91st day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally.

          Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) above with respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

Section 9.05. Deposited Money and U.S. Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

     Subject to Section 9.06 hereof, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 9.05 only, the “Trustee”) pursuant to Section 9.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this

Indenture, to the payment, either directly or through any Paying Agent (other than the Company) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal or redemption price of, and Liquidated Damages, if any, interest on, the Notes, that such money need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 9.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

          Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or U.S. Government Securities held by it as provided in Section 9.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 9.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 9.06. Repayment to the Company.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal, redemption price or purchase price of, or Liquidated Damages, if any, or interest on any Note and remaining unclaimed for two years after such amount has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof as a general creditor, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, at the expense of the Company, may cause to be published once, in The New York Times and The Wall Street Journal (national editions), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days after the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 9.07. Reinstatement.

          If the Trustee or Paying Agent is unable to apply any United States dollars or U.S. Government Securities in accordance with Section 9.02 or 9.03 hereof, as the case may be, by reason of any order of judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Company under this Indenture, and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 or 9.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 9.02 or 9.03 hereof, as the case may be; provided, however, that, if the Company makes any payment with respect to any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 10.

AMENDMENT, SUPPLEMENT AND WAIVER

Section 10.01. Without Consent of Holders of Notes.

          Notwithstanding Section 10.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note:

     (a) to cure any ambiguity, defect or inconsistency;

     (b) to provide for uncertificated Notes in addition to or in place of certificated Notes;

     (c) to provide for the assumption of the Company’s obligations to the Holders of the Notes by a successor to the Company pursuant to Article 5 hereof;

     (d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note; or

     (e) to comply with requirements of the Commission in order to effect or maintain the qualification of this Indenture under the TIA.

          Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 10.02. With Consent of Holders of Notes.

          (a) Except as provided below in this Section 10.02, this Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting solely from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). However, without the consent of each Holder affected, an amendment or waiver under this Section 10.02 may not (with respect to any Notes held by a non-consenting Holder):

     (i) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

     (ii) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes, other than Sections 4.15 and 4.16;

     (iii) reduce the rate of or change the time for payment of interest on any Note;

     (iv) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration);

     (v) make any Note payable in money other than that stated in the Notes;

     (vi) make any change in the provisions of this Indenture relating to waivers of past Defaults, including Section 6.04, or the rights of holders of notes to receive payments of principal of, or interest or premium, if any, on, the Notes;

     (vii) waive a redemption payment with respect to any Note, other than a payment required under Section 4.15 or 4.16;

     (viii) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

     (ix) make any change in the preceding amendment and waiver provisions.

          (b) Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture.

          (c) It shall not be necessary for the consent of the Holders of Notes under this Section 10.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

          (d) After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes.

Section 10.03. Compliance with Trust Indenture Act.

          Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

Section 10.04. Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 10.05. Notation on or Exchange of Notes.

          The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, in accordance with Section 2.02 with respect to those Notes, authenticate new Notes that reflect the amendment, supplement or waiver.

          Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 10.06. Trustee to Sign Amendments, etc.

          The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 10 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 10.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 11.

SATISFACTION AND DISCHARGE

Section 11.01. Satisfaction and Discharge.

          This Indenture will be discharged and will cease to be of further effect (except as set forth below) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when:

     (1) either:

     (a) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed notes which have been replaced or paid as provided in Section 2.07 and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

     (b) all Notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) will become due and payable within one year, or are

to be called for redemption within one year, under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, and premium, if any, and interest on, the Notes to the date of deposit together with irrevocable instructions from the Company directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

     (2) the Company has paid all other sums payable under this Indenture by the Company; and

     (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the Company’s obligations in Sections 2.03, 2.04, 2.06, 2.07, 2.11, 7.07, 7.08, 12.02, 12.03 and 12.04, and the Trustee’s and Paying Agent’s obligations in Section 11.02 shall survive until the Notes are no longer outstanding. Thereafter, only the Company’s obligations in Section 7.07 shall survive.

Section 11.02. Application of Trust.

          All money deposited with the Trustee pursuant to Section 11.01 shall be held in trust and, at the written direction of the Company, be invested prior to maturity in U.S. Government Securities, and applied by the Trustee in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent as the Trustee may determine, to the persons entitled thereto, of the principal (and premium, if any) and interest for the payment of which money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

ARTICLE 12.

          The Company or the Trustee, by notice to the others may designate additional or different addresses for subsequent notices or communications.

          All notices and communications (other than those sent to Holders) shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt acknowledged, if telecopied; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

          Any notice or communication to a Holder shall be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar. Any notice or communication shall also be so mailed to any person described in TIA § 313(c), to the extent required by the TIA. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.

          Except for a notice to the Trustee, which is deemed given only when received, and except as otherwise provided in this Indenture, if a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

          If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

          Where this Indenture provides for notice in any manner, such notice may be waived in writing by the person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Section 12.03. Communication by Holders of Notes with Other Holders of Notes.

          Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Company, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).

Section 12.04. Certificate and Opinion as to Conditions Precedent.

          Upon any request or application by the Company to the Trustee to take any action under this Indenture, the Company shall furnish to the Trustee:

     (a) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.05 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

     (b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.05 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been satisfied.

Section 12.05. Statements Required in Certificate or Opinion.

          Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA § 314(a)(4)) shall comply with the provisions of TIA § 314(e) and shall include:

     (a) a statement that the person making such certificate or opinion has read such covenant or condition;

     (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

     (c) a statement that, in the opinion of such person, he or she has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been satisfied; and

     (d) a statement as to whether or not, in the opinion of such person, such condition or covenant has been satisfied.

Section 12.06. Rules by Trustee and Agents.

          The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

Section 12.07. No Personal Liability of Directors, Officers, Employees and Stockholders.

          No recourse for the payment of the principal of, premium, if any, or interest or Liquidated Damages, if any, on any of the Notes, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or of any Guarantor contained in this Indenture or in any of the Notes, or because of the creation of any Indebtedness represented thereby, shall be had against any incorporator or past, present or future director, officer, employee, controlling person or stockholder of the Company or of any Guarantor. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

Section 12.08. Governing Law.

          THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE AND THE NOTES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Section 12.09. No Adverse Interpretation of Other Agreements.

          This Indenture may not be used to interpret any other indenture, loan or debt agreement of the Company or its Subsidiaries or of any other person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

Section 12.10. Successors.

          All agreements of the Company in this Indenture and the Notes shall bind its successors. All agreements of the Trustee in this Indenture shall bind its successors.

Section 12.11. Severability.

          In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 12.12. Counterpart Originals.

          The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

Section 12.13. Table of Contents, Headings, etc.

          The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

          Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

          1. Interest. Grant Prideco, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 6 1/8% per annum until maturity and shall pay the Liquidated Damages, if any, payable pursuant to Section 4 of the Registration Rights Agreement referred to below. The Company shall pay interest and Liquidated Damages, if any, semi-annually on February 15 and August 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including July 27, 2005 ² ; provided, however, that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be February 15, 2006 ³ . The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in excess of the then applicable interest rate

on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if any (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of twelve 30-day months.

          2. Method of Payment. The Company shall pay principal, premium, if any, interest and Liquidated Damages, if any, on the Notes to the persons who are registered Holders of Notes at the close of business on February 1 or August 1 next preceding the interest payment date, even if such Notes are cancelled after such record date and on or before such interest payment date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes shall be payable by wire transfer of immediately available funds to the registered Holder of the relevant Global Note and, with respect to certificated Notes, by wire transfer of immediately available funds in accordance with instructions provided by the registered holders of certificated Notes or, if no such instructions are specified, by mailing a check to each such Holder’s registered address. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

          3. Paying Agent and Registrar. Initially, Wells Fargo Bank, N.A., the Trustee under the Indenture, shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

          4. Indenture. The Company issued the Notes under an Indenture dated as of July 27, 2005 (“Indenture”) among the Company, the Trustee and the Guarantors identified therein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. C. §§ 77aaa-77bbbb), as amended. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Company may issue Additional Notes under the Indenture subject to compliance with Section 4.09 thereof, unlimited in aggregate principal amount.

          5. Optional Redemption. The Company may redeem any or all of the Notes at any time on or after August 15, 2010, upon not less than 30 nor more than 60 days’ prior notice in amounts of $1,000 or an integral multiple thereof at the redemption prices (expressed as a percentage of the principal amount) set forth below, if redeemed during the 12-month period beginning August 15 of the years indicated below:

Year		Redemption Price
2010			103.063	%
2011			102.042	%
2012			101.021	%
2013 and thereafter			100.000	%

in each case together with accrued and unpaid interest and Liquidated Damages, if any, to the date of redemption.
