The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided 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 and that reliance may be placed only on the other identification

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of their obligation to maintain an office or agency for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates Wilmington Trust, National Association, 246 Goose Lane, Suite 105, Guilford, Connecticut 06347, Attention: W.R. Grace & Co.-Conn. Administrator, as one such office or agency of the Company in accordance with Section 2.03.

Section 6.01    Events of Default.

Except where otherwise indicated by the context or where the term is otherwise defined for a specific purpose, the term “Event of Default” as used in this Indenture with respect to Notes of any series shall mean one of the following described events unless it is either inapplicable to a particular series or it is specifically deleted or modified in a supplemental indenture:

(5)    a default resulting in acceleration of Indebtedness of the Company or any Restricted Subsidiaries other than intercompany Indebtedness of at least $75 million in aggregate principal amount, which acceleration has not been rescinded or annulled after 30 days’ notice thereof;

(7)    the Company or any of its Significant Subsidiaries pursuant to or within the meaning of Bankruptcy Law:

(a)    commences a voluntary case,

(b)    consents to the entry of an order for relief against it in an involuntary case,

Section 6.02    Acceleration.

In the case of an Event of Default arising from clause (7) or (8) of Section 6.01 with respect to the Company, all outstanding Notes shall become due and payable immediately without further action or notice. If any other Event of Default with respect to the Notes of any series occurs and is continuing, the Trustee by notice to the Company or the Holders of at least 25% in principal amount of the then outstanding Notes of any series by notice to the Company and the Trustee may declare the Notes of such series to be due and payable immediately. The Holders of a majority in aggregate principal amount of the Notes of any series then outstanding by written notice to the Trustee may on behalf of all of the Holders of such series rescind an acceleration and its consequences with respect to such series of Notes if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except non-payment of principal, interest or premium that has become due solely because of the acceleration) have been cured or waived.

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 even if it 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 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 Existing Defaults.

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes of any series by notice to the Trustee may on behalf of the Holders of all of the Notes of such series waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes of such series (including in connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes of such series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 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 impair any right consequent thereon.

Section 6.05    Control by Majority.

Holders of a majority in principal amount of the then outstanding Notes of any series may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it, in each case with respect to such series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. The Trustee may take any other action which it deems proper that is not inconsistent with any such directive. 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 Holder unless such Holder shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

Section 6.06    Limitation on Suits.

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

(a)    the Holder gives to the Trustee written notice of a continuing Event of Default with respect to the series of Notes held by such Holder;

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

(c)    such Holder 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 of such series do not give the Trustee a direction inconsistent with the request.

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

Section 6.07    Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest on any Note, on or after the respective due dates expressed in such 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(1) or (2) 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, 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 Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), their creditors or their 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 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. 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 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, 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 or property pursuant to this Article VI, it shall pay out the money or property in the following order:

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

Second: to Holders for amounts due and unpaid on the Notes for principal, premium, 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, 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 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 expenses, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes of any series.

Section 7.01    Duties of Trustee.

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

(2)    Except during the continuance of an Event of Default with respect to any series of Notes:

The Trustee need not investigate any fact or matter stated in the document.

(2)    Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both.

Section 7.05    Notice of Defaults.

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee shall mail (or deliver electronically) to Holders a notice of the Default or Event of Default within 90 days after the Trustee acquires knowledge thereof. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders.

Section 7.06    Reports by Trustee to Holders.

By September 15th of each year, and for so long as any Notes remain outstanding, the Trustee shall mail to Holders 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). The Trustee also shall comply with TIA § 313(b)(2). The Trustee shall also transmit by mail or deliver electronically all reports as required by TIA § 313(c).

A copy of each report at the time of its sending to Holders shall be sent to the Company and filed with the SEC 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 or delisted on any stock exchange.

Section 7.07    Compensation and Indemnity.

The Company shall pay to the Trustee from time to time compensation as agreed upon in writing for its acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Company and the Parent Guarantor shall, jointly and severally, indemnify the Trustee and any predecessor trustee against any and all losses, liabilities, claims, damages or expenses (including reasonable legal fees and expenses) including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, damage, claim, liability or expense determined to have been caused by its own gross negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity of which a Responsible Officer has received written notice. Failure by the Trustee to so notify the Company shall not relieve the Company of their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee 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 their consent, which consent shall not be unreasonably withheld.

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

To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except such money or property held in trust by the Trustee to pay the principal of and interest on any Notes. Such Lien shall survive the resignation or removal of the Trustee and 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(7) or (8) occurs, the expenses and the compensation for the services (including the fees 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 the 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 7.08.

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 a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

(a)    the Trustee fails to comply with Section 7.10;

(b)    the Trustee is adjudged as bankrupt or as insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(c)    a custodian or public officer takes charge of the Trustee or its property; or

(d)    the Trustee becomes incapable of acting.

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 at least 10% in principal amount of the then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder 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. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and 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 shall continue for the benefit of the retiring Trustee.

Section 7.09    Successor Trustee by Merger, etc.

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 of such series, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and (b) 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 such instruments reasonably requested by the Company acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(d)    the Legal Defeasance provisions of this Indenture;

Subject to compliance with this Article VIII, the Company may exercise their option under this Section 8.02 notwithstanding the prior exercise of their option under Section 8.03.

Section 8.03    Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04, be released from their obligations under the covenants contained in Article V with respect to the outstanding Notes of such series on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes of such series 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 of such series, 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, 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 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, Sections 6.01(3) through 6.01(5) shall not constitute Events of Default.

Section 8.04    Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance pursuant to Section 8.02 or Covenant Defeasance pursuant to Section 8.03, the following conditions must be met:

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

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

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

(b)    since the date such Notes were first issued, 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 of the outstanding Notes 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 reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes 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 (other than resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing)):

(5)    such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;

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

(7)    the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

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,

(a)    have become due and payable or

(b)    will become due and payable on the maturity date within one year, by their terms or 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 8.05    Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 in respect of the outstanding Notes shall be held in trust 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 (including the Company acting as Paying Agent) as the Trustee may determine, to Holders of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but 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 non-callable Government Securities deposited pursuant to Section 8.04 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 VIII 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 non-callable Government Securities held by it as provided in Section 8.04 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 8.04(1)), 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 8.06    Repayment to Company.

Subject to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on their 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, 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, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company.

Section 8.07    Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Notes, shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of their obligations, the Company shall be subrogated to the rights of Holders to receive such payment from the money held by the Trustee or Paying Agent.

Section 9.01    Without Consent of Holders of Notes.

Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Notes of any series without the consent of any Holder of a Note of such series to:

(2)    provide for the assumption by a successor corporation of the obligations of the Company;

(9)    comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA;

(10)    conform this Indenture, as amended and supplemented, or the Notes, as amended or supplemented, to the description and terms of such Notes in the offering memorandum, prospectus supplement or other offering document applicable to such Notes at the time of the initial sale thereof;

(11)    supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Notes so long as any such action shall not adversely affect the interests of any holder of such series of Notes or any other series of debt securities issued thereunder;

(12)    prohibit the authentication and delivery of additional series of Notes;

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

(14)    establishing the form or terms of other debt securities issued under this Indenture and coupons of any series of such other debt securities pursuant to this Indenture and to change the procedures for transferring and exchanging such other debt securities so long as such change does not adversely affect the holders of any outstanding debt securities, including the Notes (except as required by applicable securities laws);

(15)    make any change to this Indenture that does not adversely affect the rights of any Holder of any series of debt securities, including the Notes;

(16)    secure any series of debt securities, including the Notes;

(17)    evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to one or more series of Notes and to add to or change any of the provisions of this Indenture as shall be necessary for or to facilitate the administration of the trusts hereunder by more than one Trustee;

(18)    comply with the merger and consolidation provisions pursuant to this Indenture;

(19)    in the case of subordinated debt securities, making any change to the provisions of this Indenture or any supplemental indenture relating to subordination that would limit or terminate the benefits available to any holder of Senior Indebtedness under such provisions (but only if each such holder of Senior Indebtedness under such provisions consents to such change);

(20)    evidence the release of any guarantor pursuant to the terms of this Indenture; or

(21)    provide for the form of Note for any series of Notes.

Upon the request of the Company, and upon receipt by the Trustee an Officers’ Certificate and an Opinion of Counsel pursuant to Section 9.06, 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 9.02    With Consent of Holders of Notes.

Except as provided below in this Section 9.02, this Indenture or the Notes of any series may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes of each series affected (including, without limitation, consents obtained in connection with a purchase of, or a tender offer or exchange offer for, Notes) and, subject to Sections 6.04 and 6.07, any existing Default or compliance with any provision of this Indenture or the Notes of any series may be waived, including by way of amendment, with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes of each series affected (including, without limitation, consents obtained in connection with a purchase of, or a tender offer or exchange offer for, Notes). Section 2.08 shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.

Upon the request of the Company and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of such Notes as aforesaid, and upon receipt by the Trustee of an Officers’ Certificate and an Opinion of Counsel pursuant to Section 9.06, the Trustee shall join with the Company in the execution of any amended or supplemental indenture unless such amended or supplemental indenture 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.

It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail or deliver electronically to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send 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, the Holders of a majority in aggregate principal amount of the outstanding Notes of each affected series may waive compliance in a particular instance by the Company with any provision of this Indenture or such Notes. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1)    extend the maturity of any payment of principal of or any installment of interest on any Notes of such series;

(2)    reduce the principal amount of any Note of such series, or the interest, including additional interest, thereon, or any premium payable on any Note of such series upon redemption thereof;

(3)    change our obligation to pay additional amounts;

(4)    change any place of payment where, or the currency in which, any Note of such series or any premium or interest is denominated as payable;

(5)    change the ranking of the Notes of such series;

(6)    impair the right to sue for the enforcement of any payment on or with respect to any Note of such series; or

(7)    reduce the percentage in principal amount of outstanding Notes of such series required to consent to any supplemental indenture, any waiver of compliance with provisions of this Indenture or specific defaults and their consequences provided for in this Indenture, or otherwise modify the sections in this Indenture relating to these consents.

Section 9.03    Compliance with Trust Indenture Act.

[Reserved].

Section 9.04    Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent thereto by a Holder is a continuing consent by the Holder 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 or subsequent Holder 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 9.05    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, 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 9.06    Trustee to Sign Amendments, etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.01) shall be fully protected in relying upon, in addition to the documents required by Section 11.04, an Officers’ Certificate and an Opinion of Counsel, in each case from the Company, stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

Section 10.01    Guarantee.

(a)    Parent Guarantor and to the extent applicable, each other Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees, as a primary obligor and not merely as a surety, to each Holder and to the Trustee (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption

or otherwise, of all obligations of the Company under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal of, premium, if any, or interest on in respect of the Notes and all other monetary obligations of the Company under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from any Guarantor, and that each Guarantor shall remain bound under this Article X notwithstanding any extension or renewal of any Guaranteed Obligation.

(b)    Parent Guarantor and to the extent applicable, each other Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee 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 or otherwise; (ii) any extension or renewal of this Indenture, the Notes or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (v) any change in the ownership of each Guarantor, except as provided in Section 10.02(b) or Section 10.02(c). Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed.

(c)    Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such Guarantor.

(d)    Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(e)    The Note Guarantee of each Guarantor is, to the extent and in the manner set forth in Article X, equal in right of payment to all existing and future pari passu Indebtedness, senior in right of payment to all existing and future subordinated Indebtedness of the Company and subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all secured Indebtedness of the relevant Guarantor and is made subject to such provisions of this Indenture.

(f)    Except as expressly set forth in Sections 8.02, 10.02 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, 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 Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any holder or the Trustee 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 any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

(g)    Each Guarantor agrees that its Note Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each Guarantor further agrees that its Guarantee 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 or interest

on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(h)    In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor 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 or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Company to Holders and the Trustee.

(i)    Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article VI, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Parent Guarantor for the purposes of this Section 10.01.

(j)    Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any holder in enforcing any rights under this Section 10.01.

(k)    Upon request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

(l)    The foregoing is subject to any limitations required by applicable law.

Section 10.02    Limitation on Liability.

(f)    Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by each Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(g)    A Guarantee by any Guarantor including any Subsidiary Guarantor that executes a supplemental indenture in accordance with Section 10.06 and provides a guarantee shall automatically terminate and be of no further force or effect and such Guarantor shall be deemed to be released from all obligations under this Article 10 upon:

(i)    upon the sale or other disposition (including by way of consolidation or merger), in one transaction or a series of related transactions, of at least a majority of the total voting power of the Capital Stock or other interests of such guarantor (other than to the Company or any of its Domestic Subsidiaries), as permitted under the indenture;

(ii)    upon the sale or disposition of all or substantially all the assets of such Guarantor (other than to the Company or any of its Domestic Subsidiaries), as permitted hereunder;

(iii)    or if at any time when no Default has occurred and is continuing with respect to the series of Notes with respect to which the Guarantee is being released, such Guarantor no longer guarantees (or which

Guarantee is being simultaneously released or will be immediately released after the release of the Guarantor) the Senior Indebtedness of the company under the Credit Agreement.

(iv)    the release or discharge of the guarantee of any other Indebtedness which resulted in the obligation to guarantee the Notes; and

(v)    the Company’s exercise of its legal defeasance option or covenant defeasance option under Article VIII or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture.

Section 10.03    Successors and Assigns.

Subject to Section 10.02 and this Indentures, this Article X shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 10.04    No Waiver.

Neither a failure nor a delay on the part of either the Trustee or Holders in exercising any right, power or privilege under this Article X shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article X at law, in equity, by statute or otherwise.

Section 10.05    Modification.

No modification, amendment or waiver of any provision of this Article X, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle any Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 10.06    Execution of Supplemental Indenture for Future Guarantors.

Each Subsidiary and other Person which is required to become a Guarantor of any series of Notes pursuant to the terms of this Indenture (as supplemented by the supplemental indenture with respect to such Notes) shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit E hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article X and shall guarantee the Notes. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a valid and binding obligation of such guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

Section 10.07    Non-Impairment.

The failure to endorse a Guarantee on any Note shall not affect or impair the validity thereof.

Section 11.01    Trust Indenture Act Controls.
