No remedy conferred in this Indenture upon the Trustee or any Holder of a Note is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to every other remedy conferred herein or now or hereafter existing at law or in equity or by statute or otherwise.

Anything to the contrary notwithstanding contained in this (S) 7.06, the parties to this Indenture and the Noteholders agree that the court may in its discretion require, 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 them, or either of them, as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided, however, that the provisions of this paragraph shall not apply to any suit instituted, directly or through an agent or agents, by the Trustee, to any suit instituted by any Noteholder or group of Noteholders holding in the aggregate at least 25% of the aggregate principal amount of the Notes Outstanding, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or interest or Yield-Maintenance Amount, if any, on its Notes at and after maturity of such principal or interest as expressed in such Notes. (S) 7.07. ACTION BY TRUSTEE WITHOUT POSSESSION OF NOTES. All rights of action under this Indenture or under any of the Notes enforceable by the Trustee may be enforced by the Trustee without the possession of any such Notes, or the production thereof on the trial or other proceedings relative thereto, and any such suit or proceedings instituted by the Trustee shall be brought in its own name as Trustee for the ratable benefit of the Holders of the Notes, subject to the provisions of this Indenture. (S) 7.08. FILING OF DOCUMENTS BY TRUSTEE; ATTORNEY-IN-FACT.

The Trustee is hereby irrevocably appointed (and the successive respective Holders of the Notes by taking and holding the same shall be conclusively deemed to have so appointed the Trustee) the true and lawful attorney-in-fact of the respective Holders of the Notes, with authority to make and file in the respective names of the Holders of the Notes, or on behalf of the Holders of the Notes as a class, subject to deduction from any such claims of the amounts of any claims filed by any of the Holders of the Notes, any proof of debt, amendment of proof of debt, claims, petition or other documents in any such proceedings and to receive payment of any sums becoming 41 distributable on account thereof, and to execute any other papers and documents and to do and perform any and all acts and things for and on behalf of such Holders of the Notes, as may be necessary or advisable in the opinion of the Trustee in order to have the respective claims of the Trustee and of the Holders of the Notes against the Company or its property allowed in any such proceeding, and to receive payment of or on account of such claims; provided, however, that nothing contained in this Indenture shall be deemed to give to the Trustee any right to accept or consent to any plan of reorganization or otherwise by action of any character in any such proceeding to waive or change in any way any right of any Noteholder. (S) 7.09. NO WAIVER. No delay or omission of the Trustee or of the Noteholders to exercise any right or power accruing upon any Event of Default shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or acquiescence therein; and every right and power given by this Article Seven to the Trustee may be exercised from time to time and as often as may be deemed expedient by the Trustee. (S) 7.10. NOTES DEEMED NOT OUTSTANDING.

(S) 7.12. REMEDIES SUBJECT TO APPLICABLE LAWS. All rights, remedies and powers provided by this Article Seven may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law in the premises, and all the provisions of this Article Seven are intended to be subject to all applicable mandatory provisions of law that may be controlling in the premises and to be limited to the extent necessary so that they will not render this Indenture invalid, unenforceable or not entitled to be recorded or filed under the provisions of any applicable law. ARTICLE EIGHT EVIDENCE OF RIGHTS OF NOTEHOLDERS Any demand, request, consent or other instrument which this Indenture may require or permit to be signed and executed by the Noteholders may be signed in any number of concurrent instruments of similar tenor and may be signed or executed by such Noteholders in person or by attorney appointed in writing. Proof of the execution of any such demand, request, consent or other instrument, or of a writing appointing any such attorney, or of the holding by any Person of the Notes, shall, subject to the provisions of (S) 10.02, be sufficient for any purpose of this Indenture if 42 the fact and date of the execution by any Person of such demand, request, consent or other instrument or writing and, in the case of an agent, fiduciary or representative, the authority of such person may be proved by the certificate of any notary public, or other officer authorized to take acknowledgments of deeds to be recorded in any state, that the person signing the same acknowledged to him the execution thereof, or by an affidavit of a witness of such execution. The Trustee may nevertheless in its discretion require other or further proof in cases where it deems other or further proof appropriate or desirable.

In default of such payment by the Company, the Trustee shall have a Lien therefor on any moneys held by the Trustee hereunder prior to any rights in such moneys of the Holders of the Notes.

(j) Subject to the provisions of (S) 10.02, the Trustee may, whenever it shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering any action hereunder, deem such matter to be conclusively proved and established by an Officers' Certificate delivered to it (unless other evidence in respect thereof is herein specifically prescribed), and such certificate shall be full warrant to the Trustee for any action taken or suffered by it under the provisions of this Indenture in reliance upon such certificate. 45 (S) 10.02. EXTENT OF TRUSTEE LIABILITY. None of the provisions of this Indenture shall be construed as relieving the Trustee from liability for its own grossly negligent action, grossly negligent failure to act, or wilful misconduct, except that anything in this Indenture contained to the contrary notwithstanding: (a) unless and until an Event of Default specified in (S) 7.01 hereof shall have occurred and be continuing, (i) the Trustee shall not be liable except for the performance of such duties as are specifically set out in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee, whose duties and obligations shall be determined solely by the express provisions of this Indenture; and (ii) the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, in the absence of bad faith on the part of the Trustee, upon certificates or opinions furnished to it pursuant to the express provisions of and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions, which, by the provisions of this Indenture, are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; (b) the Trustee shall not be personally liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts; and (c) the Trustee shall not be personally liable to any Holder of Notes or to any other Person with respect to any action taken or omitted to be taken by it in good faith, in accordance with the direction of the Required Holder(s) of the Notes of all series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred upon the Trustee by this Indenture. If an Event of Default specified in (S) 7.01 hereof shall have happened, then, so long as the same shall be continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and shall use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. Notwithstanding any provisions of this Indenture authorizing the Trustee conclusively to rely upon any resolutions, certificates, statements, opinions, reports, orders or other instruments, the Trustee may, but to the extent permitted by this (S) 10.02, need not, require any further evidence or make any further investigation as to the facts or matters stated therein which it may, in good faith, deem reasonable in the circumstances, and the Trustee shall, if requested in writing so to do by the 46 Required Holder(s) of the Notes of all series, require such further evidence or make such further investigation, provided, however, that, if the payment within a reasonable time to the Trustee of the cost, expenses and liabilities likely to be incurred by it in making such investigation is not reasonably assured to it under the terms of this Indenture, the Trustee may require reasonable indemnity against such expense or liability as a condition to so proceeding. If the Trustee shall determine or shall be requested, as aforesaid, to make such further investigation, it shall be entitled to examine the books, records and premises of the Company; and unless satisfied, with or without such investigation, of the truth and accuracy of the matters stated in such resolutions, certificates, statements, opinions, reports, orders or other instruments, the Trustee shall be under no obligation to grant any application or take or permit any action hereunder. The reasonable expense of every such examination shall be paid by the Company, or, if paid by the Trustee, shall be reimbursed by the Company, upon demand. (S) 10.03. NOTICE OF DEFAULTS. The Trustee shall provide written notice by mail to each Registered Owner of Notes of the happening of all Defaults and Events of Default known to the Trustee, within 10 days after the occurrence thereof; provided, that, except in the case of a Default resulting from the failure to make any payment of principal or of interest or Yield- Maintenance Amount, if any, on the Notes, the Trustee shall be protected in withholding such notice if and provided, however, that the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Noteholders. Nothing herein contained shall require the Trustee to give any notice of any Default or Event of Default which has been cured. (S) 10.04. CONFLICTING INTEREST OF TRUSTEE. The Trustee and any successor trustee shall comply at all times with Section 310 of the Trust Indenture Act; provided, that this (S) 10.04 shall not be effective unless and until this Indenture is qualified under the Trust Indenture Act. (S) 10.05. QUALIFICATIONS OF TRUSTEE; RESIGNATION. If the Trustee shall at any time cease to be a bank or trust company in good standing organized and doing business under the laws of the United States or of any State and having its principal office in The City of New York or Pittsburgh or in such other city as the Company and the Required Holder(s) of all series of Notes shall select and having a combined capital and surplus of not less than $350,000,000 which is authorized under the laws of the jurisdiction of incorporation to exercise corporate trust powers and is subject to supervision or examination by Federal or State authority, then the Trustee shall resign within thirty (30) days thereafter, such resignation to become effective upon the appointment of a successor trustee and such successor's acceptance of such appointment. If the Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, the combined capital and surplus of the Trustee shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. 47 If the Trustee shall fail or refuse to resign within said period, or if, after the provisions of (S) 10.04 shall have become effective, the Trustee has or shall acquire any conflicting interest of the character specified in Section 310 of the Trust Indenture Act and shall fail or refuse either to eliminate such conflicting interest or to resign within the period provided in respect of such resignation, then in either such event (i) the Trustee shall, within ten (10) days after the expiration of said period, transmit notice of such failure or refusal to the Noteholders in the manner and to the extent provided in Section 313(e) of the Trust Indenture Act; and (ii) any Noteholder, who has been the bona fide Holder of a Note for at least six months, may, subject to the provisions of (S) 7.11 hereof and upon obtaining consent from Holders of at least 25% of the aggregate principal amount of the Notes, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor, if such Trustee fails, after written request therefor by such Noteholder, to comply with the provisions of said (S) 10.04; provided, however, that no such petition may be made by reason of any failure to comply with the provisions of (S) 10.04 until the provisions thereof shall have become effective. (S) 10.06. RESIGNATION AND REMOVAL; SUCCESSOR TRUSTEE. The Trustee or any successor may resign and be discharged from the trust hereby created by giving notice thereof to the Company specifying the date when such resignation shall take effect, and by giving notice thereof by mail to the Registered Owners of all Notes. Except as otherwise required under the Trust Indenture Act with respect to a resignation which takes place at any time after this Indenture has been qualified under the Trust Indenture Act, such resignation shall take effect on the date specified in such notice unless previously a successor shall have been appointed as hereinafter provided, in which event such resignation shall take effect upon the appointment of such successor. The Trustee or any successor may be removed at any time by an instrument or instruments in writing delivered to the Trustee and to the Company, and a successor may be appointed by an instrument or instruments in writing delivered to such successor and to the Company, in either case signed by the Required Holder(s) of all series of Notes or by their duly authorized attorneys-in-fact; but the Company, by an instrument executed by order of the Board of Directors, shall appoint a successor to fill the vacancy until a successor shall be appointed by the Noteholders or a court of competent jurisdiction as herein authorized. Every successor to the Trustee so appointed by the Noteholders, by a court of competent jurisdiction or by the Company, shall be a bank or trust company in good standing organized and doing business under the laws of the United States or of any State and having its principal office in The City of New York or Pittsburgh or any other city as the Company and the Required Holder(s) of all series of Notes shall select, and having a combined capital and surplus of not less than $350,000,000, which is authorized under the laws of the jurisdiction of incorporation to exercise corporate trust powers and is subject to supervision or examination by a Federal or State authority. If such successor publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, the combined capital and surplus of such successor shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. 48 If in a proper case no appointment of a successor shall be made pursuant to the foregoing provisions of this Article Ten within six months after a vacancy shall have occurred, the Holder of any Note or the retiring Trustee may apply to any court of competent jurisdiction to appoint a successor. Said court may thereupon, after such notice, if any, as such court may deem proper and prescribe, appoint a successor. (S) 10.07. ACCEPTANCE BY SUCCESSOR TRUSTEE. Any successor to the Trustee appointed under any of the methods herein provided shall execute, acknowledge and deliver to its predecessor trustee, and to the Company, an instrument in writing accepting such appointment hereunder and thereupon such successor, without any further act, deed or conveyance, shall become fully vested with the rights, powers and trusts of its predecessor in the trust hereunder with like effect as if originally named as Trustee herein, as the case may be; but such predecessor shall, nevertheless, at the written request of the successor, execute and deliver an instrument transferring to the successor all the rights, powers and trusts of such predecessor hereunder and shall duly assign, transfer and deliver all property and moneys held by it to its successor. Should any instrument in writing from the Company be required by any successor for more fully and effectually vesting in and confirming to it or him all rights, powers and duties as trustee hereunder, the Company, upon the request of such successor, shall make, execute and deliver the same. The Company shall promptly give notice of the appointment of such successor by mail to the Registered Owners of all Notes. (S) 10.08. MERGER OR CONSOLIDATION. Any corporation into which the Trustee or any successor to it in the trust created by this Indenture may be merged, or with which it or any successor to it may be consolidated, or any corporation resulting from any merger or consolidation to which the Trustee or any successor to it shall be a party, shall be the successor of the Trustee under this Indenture without the execution or filing of any instruments or any further act on the part of any of the parties hereto. (S) 10.09. TRUSTEE AS CREDITOR. (a) If the Trustee in its individual capacity shall be, or shall become, a creditor, directly or indirectly, secured or unsecured, of the Company (other than in a relationship of the nature specified in paragraph (f) of this (S) 10.09) within four months prior to a default, as the term "DEFAULT" is defined in paragraph (e) of this (S) 10.09 or subsequent to such a default, then, unless and until such default shall be cured, the Trustee shall set apart and hold in a special account for the benefit of the Trustee individually, the Holders of Notes and the holders of any other indenture securities, as the term "OTHER INDENTURE SECURITIES" is defined in said paragraph (e): (i) an amount equal to any and all reductions in the amount due and owing upon any claim as such creditor in respect of principal or interest, effected after the beginning of such four months' period and valid as against the Company and its other creditors, except any such reduction resulting from the receipt or disposition of any property described in clause (ii) of this paragraph (a), or from the exercise of any right of set-off which the Trustee could have exercised, if any voluntary or involuntary case had been commenced in respect of the Company under the Federal bankruptcy laws, as now or hereafter constituted, or any other 49 applicable Federal or State bankruptcy, insolvency or other similar law upon the date of such default; and (ii) all property received by the Trustee in respect of any claim as such creditor, either as security therefor, or in satisfaction or composition thereof or otherwise, after the beginning of such four months' period, or an amount equal to the proceeds of any such property, if disposed of, subject, however, to the rights, if any, of the Company and its other creditors in such property or such proceeds. (b) Nothing contained in this (S) 10.09 shall affect the right of the Trustee: (i) to retain for its own account (A) payments made on account of any such claim by any Person (other than the Company) who is liable thereon, (B) the proceeds of the bona fide sale of any such claim by the Trustee to a third Person, and (C) distributions made in cash, securities or other property in respect of claims filed against the Company in bankruptcy or receivership or in proceedings for reorganization pursuant to the Federal bankruptcy laws, as now or hereafter constituted, or applicable State law; (ii) to realize, for its own account, upon any property held by it as security for any such claim, if such property was so held prior to the beginning of such four months' period; (iii) to realize, for its own account, but only to the extent of the claim hereinafter mentioned, upon any property held by it as security for any such claim, if such claim was created after the beginning of such four months' period and such property was received as security therefor simultaneously with the creation thereof, and if the Trustee shall sustain the burden of proving that at the time such property was so received the Trustee had no reasonable cause to believe that a default, as defined in paragraph (e) of this (S) 10.09, would occur within four months; or (iv) to receive payment on any claim referred to in clause (ii) or clause (iii) of this paragraph (b), against the release of any property held as security for such claim as provided in said clause (ii) or said clause (iii), as the case may be, to the extent of the fair value of such property. For the purposes of clauses (ii), (iii) and (iv) of this paragraph (b), property substituted after the beginning of such four months' period for property held as security at the time of such substitution shall, to the extent of the fair value of the property released, have the same status as the property released, and, to the extent that any claim referred to in any of such paragraphs is created in renewal of, or in substitution for, or for the purpose of repaying or refunding, any pre-existing claim of the Trustee as such creditor, such claim shall have the same status as such pre-existing claim. 50 (c) If the Trustee shall be required to account, as in this (S) 10.09 provided, the funds and property held in a special account pursuant to the provisions of this (S) 10.09 and the proceeds thereof shall be apportioned among the Trustee, the Holders of Notes and the holders of other indenture securities in such manner that the Trustee, the Holders of Notes and the holders of other indenture securities realize, as a result of payments from such special account and payments of dividends on claims filed against the Company in receivership or liquidation proceedings or any voluntary or involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or applicable state law, the same percentage of their respective claims, figured before crediting to the claim of the Trustee anything on account of the receipt by it from the Company of the funds and property in such special account, and before crediting to the respective claims of the Trustee, the Holders of Notes and the holders of other indenture securities, dividends on claims filed against the Company in receivership or liquidation proceedings or any voluntary or involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or applicable state law, but after crediting thereon receipts on account of the indebtedness represented by their respective claims from all sources other than from such dividends and from the funds and property so held in such special account. As used in this paragraph (c) with respect to any claim, the term "DIVIDENDS" shall include any distribution with respect to such claim in receivership or liquidation proceedings or any voluntary or involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or applicable state law, whether such distribution is made in cash, securities or other property, but shall not include any such distribution with respect to the secured portion, if any, of such claim. The court in which such receivership or liquidation proceeding or such voluntary or involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or applicable state law shall be pending shall have jurisdiction (i) to apportion among the Trustee, the Holders of Notes and holders of other indenture securities, in accordance with the provisions of this paragraph (c), the funds and property held in such special account and the proceeds thereof, or (ii) in lieu of such an apportionment thereof, in whole or in part, to give to the provisions of this paragraph (c) due consideration in determining the fairness of the distributions to be made to the Trustee, the Holders of Notes and the holders of other indenture securities with respect to their respective claims, in which event it shall not be necessary to liquidate or to appraise the value of any securities or other property held in such special account or as security for any such claim, or to make a specific allocation of such distributions as between the secured and unsecured portions of such claims, or otherwise to apply the provisions of this paragraph (c) as a mathematical formula. (d) In case the Trustee shall have resigned or been removed after the beginning of such four months' period, the Trustee shall be subject to the provisions of this (S) 10.09 as though such resignation or removal had not occurred. If the Trustee shall have resigned or been removed prior to the beginning of such four months' period, it shall be subject to the provisions of this (S) 10.09 if and only if the receipt of property or reduction of claim which would have given rise to the obligation to account, if the Trustee had continued as such trustee hereunder, occurred after the beginning of such four months' period and within four months after such resignation or removal. 51 (e) As used in this (S) 10.09, the term "DEFAULT" means any failure to make payment in full of principal of or interest on the Notes or an other indenture securities, when and as such principal or interest becomes due and payable; and the term "OTHER INDENTURE SECURITIES" means securities upon which the Company is an obligor (as the term "OBLIGOR" is defined in the Trust Indenture Act of 1939) outstanding under any other indenture which is qualified under the Trust Indenture Act of 1939 and under which the Trustee is also trustee and under which a default exists at the time of the apportionment of the funds and property held in said special account. (f) None of the foregoing provisions of this (S) 10.09 shall be applicable in respect of a creditor relationship arising from: (i) the ownership or acquisition of securities issued under any indenture, or any security or securities having a maturity of one year or more at the time of acquisition by the Trustee; (ii) disbursements made in the ordinary course of business in the capacity of trustee under an indenture, transfer agent, registrar, custodian, paying agent, fiscal agent or depositary, or other similar capacity; (iii) an indebtedness created as a result of services rendered or premises rented. or an indebtedness created as a result of goods or securities sold in a cash transaction, as defined in this paragraph (f); (iv) the ownership of stock or of other securities of a corporation organized under the provisions of Section 25(a) of the Federal Reserve Act, as amended, which is directly or indirectly a creditor of the Company; or (v) the acquisition, ownership, acceptance, or negotiation of any drafts, bills of exchange, acceptances or obligations which fall within the classification of self-liquidating paper, as the term "SELF-LIQUIDATING PAPER" is defined in this paragraph (f). The term "SECURITY" or "SECURITIES" as used in this paragraph (f) shall mean any note, stock, treasury stock, bond, debenture, evidence of indebtedness, certificate of interest or participation in any profit sharing agreement, collateral-trust certificate, preorganization certificate or subscription, transferable share, investment contract, voting trust certificate, certificate of deposit for a security, fractional undivided interest in oil, gas or other mineral rights, or, in general, any interest or instrument commonly known as a "SECURITY," or any certificate of interest or participation in, temporary or interim certificate for, receipt for, guarantee of, or warrant or right to subscribe to or purchase, any of the foregoing. 52 The term "CASH TRANSACTION" as used in paragraph (iii) of this paragraph (f) means any transaction in which full payment for goods or securities sold is made within seven days after the delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand. The term "SELF-LIQUIDATING PAPER" as used in paragraph (v) of this paragraph (f) means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company for the purpose of financing the purchase, processing, manufacture, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of or lien upon the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided that the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company arising from the making, drawing, negotiating or incurring of the draft bill of exchange, acceptance or obligation. In the event that any Person other than the Company shall at any time become an obligor upon any of the Notes, so long as such Person shall continue to be such obligor the provisions of this (S) 10.09, in addition to being applicable to the Trustee and the Company, shall be applicable to the Trustee and such obligor. (S) 10.10. REPORTING REQUIREMENTS. The Trustee and any successor trustee shall comply at all times with Section 313 of the Trust Indenture Act; provided, that this (S) 10.10 shall not be effective unless and until this Indenture is qualified under the Trust Indenture Act. (S) 10.11. PRESERVATION OF NOTEHOLDER INFORMATION. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders of Notes (i) contained in the most recent list furnished to it as provided in (S) 4.03 and (ii) otherwise received by it. The Trustee may (A) destroy any list furnished to it as provided in (S) 4.03 upon receipt of a new list so furnished, (B) destroy any other information received by it regarding the names and addresses of the Noteholders upon delivering to itself as Trustee, not earlier than 45 days after an interest payment date of the Notes, a list containing the names and addresses of the Holders of the Notes obtained from such information since the delivery of the next previous list, if any, and (C) destroy any list delivered to itself as Trustee which was compiled from information received by it upon the receipt of a new list so delivered. (b) Within five Business Days after receipt by the Trustee of a written application by any three or more Noteholders stating that the applicants desire to communicate with other Noteholders with respect to their rights under this Indenture or under the Notes, and accompanied by a copy of the form of proxy or other communication which such applicants propose to transmit, and by reasonable proof that each such applicant has owned a Note or Notes for a period of at least six months preceding such application, the Trustee shall, as its election. either (i) afford to such 53 applicants access to the information preserved at the time by the Trustee in accordance with the provisions of paragraph (a) of this (S) 10.11, or (ii) inform such applicants as to the approximate number of Noteholders whose names and addresses appear in the information preserved at the time by the Trustee in accordance with the provisions of paragraph (a) of this (S) 10.11, and as to the approximate cost of mailing to the Noteholders the form of proxy or other communication, if any, specified in such application. If the Trustee shall elect not to afford to such applicants access to such information, the Trustee shall, upon the written request of each applicant, mail to all Noteholders whose names and addresses appear in the information preserved at the time by the Trustee in accordance with the provisions of paragraph (a) of this (S) 10.11 copies of the form of proxy or other communication which is specified in such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and the payment, or provision for the payment, of the reasonable expenses of such mailing, unless within five days after such tender, the Trustee shall mail to such applicants, and file with the Securities and Exchange Commission, together with a copy of the material to be mailed, a written statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the Noteholders or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. In such event the applicant Noteholder shall be entitled to make application to the Securities and Exchange Commission for an order directing the Trustee to mail such material as aforesaid. If, after notice to the Trustee and hearing on the request so made by the applicant Noteholder, the Securities and Exchange Commission determines that the Trustee should be required to mail such material as aforesaid, the Trustee agrees to comply with such determination with reasonable promptness after such determination and the renewal of the aforesaid tender. The Trustee shall not be liable or accountable to the Company or to any Noteholder by reason of the disclosure of any such information as to the names and addresses of the Noteholders in accordance with the provisions of this (S) 10.11, regardless of the source from which such information was derived, nor by reason of the mailing of any material pursuant to request made under this (S) 10.11. Notwithstanding any provision contained herein to the contrary, the provisions of this (S) 10.11(b) shall not be effective unless and until this Indenture is qualified under the Trust Indenture Act of 1939. (S) 10.12. DEALINGS WITH COMPANY. The Trustee may acquire and hold Notes and otherwise deal with the Company in the same manner and to the same extent and with like effect as though it were not the Trustee hereunder; subject, however, to the provisions of (S) 10.04, (S) 10.09 and (S) 10.10, if such provisions are then in effect. (S) 10.13. COMPLIANCE WITH SEC RULES AND REGULATIONS. The Trustee may in good faith comply with any rule, regulation or order of the Securities and Exchange Commission made pursuant to the terms and provisions of the Trust Indenture Act of 1939 and shall be fully protected in so doing notwithstanding that such rule, regulation or order may thereafter be amended or rescinded or determined by judicial or other authority to be invalid for any reason, but nothing 54 herein contained shall require the Trustee to take any action or omit to take any action in accordance with such rule, regulation or order, except as in this Indenture otherwise required. ARTICLE ELEVEN SUPPLEMENTAL INDENTURES (S) 11.01. PERMITTED PURPOSES. In addition to any Supplemental Indenture otherwise authorized by this Indenture, the Company, when authorized by resolution of the Board of Directors and the Trustee, from time to time and at any time, subject to the conditions and restrictions in this Indenture contained, may enter into an Indenture or Indentures Supplemental hereto and which thereafter shall form a part hereof for any one or more or all of the following purposes: (a) to close this Indenture against, or to restrict, in addition to the limitations and restrictions herein contained, the authentication and delivery of Additional Notes hereunder by imposing additional conditions and restrictions to be thereafter observed, whether applicable in respect of all Notes authenticated and delivered and to be authenticated and delivered hereunder or in respect of one or more series thereof, or otherwise; (b) to add, to the covenants and agreements of the Company in this Indenture contained, other covenants and agreements thereafter to be observed and to surrender any right or power herein reserved to or conferred upon the Company although the freedom of action of the Company may be materially restricted thereby; (c) to make such provisions in regard to matters or questions arising under this Indenture as may be necessary or desirable and not inconsistent with this Indenture; (d) to modify any of the provisions of this Indenture or to relieve the Company from any of the obligations, conditions or restrictions herein contained, provided that, except as permitted by Article Twelve, no such modification shall be or become operative or effective which shall in any manner impair any of the rights of the Noteholders or of the Trustee while any Notes of any series established prior to the execution of such Supplemental Indenture shall remain Outstanding, and provided, further, that such Supplemental Indenture shall be specifically referred to in the text of all Notes of any series established after the execution of such Supplemental Indenture; and provided, also, that the Trustee may in its discretion decline to enter into any such Supplemental Indenture which in its opinion may not afford adequate protection to the Trustee when the same shall become operative; (e) to set forth the terms of any Additional Notes to be issued hereunder; 55 (f) to modify, amend or supplement this Indenture or any Supplemental Indenture hereto in such a manner as to permit the qualification thereof under the Trust Indenture Act of 1939 or any similar Federal statute hereafter in effect, except that nothing herein contained shall authorize the inclusion in any Supplemental Indenture hereto of the provision referred to in Section 316(a)(2) of said Trust Indenture Act of 1939 or any corresponding provision provided for in any similar Federal statute hereafter in effect; or (g) for any other purpose not inconsistent with the terms of this Indenture, or for the purpose of curing any ambiguity or curing, correcting or supplementing any defect or inconsistent provision contained in this Indenture or any Supplemental Indenture; and the Company hereby covenants that it will fully perform all the requirements of any such Supplemental Indentures which may be in effect from time to time; but no restriction or obligation imposed hereby or by any Supplemental Indenture upon the Company in respect to any of the Notes or series of Notes then Outstanding under this Indenture may, except as otherwise provided in this Indenture, be waived or modified by such Supplemental Indentures, or otherwise.

Every proxy shall be signed by the Noteholder himself or by his duly authorized attorney, as the case may be, and shall be witnessed, and its genuineness if questioned shall be established to the satisfaction of the Inspectors of Votes. All proxies and certificates presented at any meeting shall be delivered to the Inspectors of Votes and filed with the Trustee. Officers and nominees of the Company and of the Trustee may attend at any such meeting and take part therein, but shall not be entitled to vote thereat except to the extent that they may be Noteholders or may hold proxies of Noteholders. (S) 12.04. CHAIRMAN AND SECRETARY; INSPECTOR OF VOTES. Persons named by the Trustee, if represented at the meeting, shall act as temporary Chairman and Secretary, respectively, of the meeting, but if the Trustee shall not be represented or shall fail to nominate such persons or if any person so nominated shall not be present, then the Noteholders and proxies present shall by a majority vote, irrespective of the amount of their holdings, elect other persons from those present to fill such vacancy or vacancies. A permanent Chairman and a permanent Secretary of such meeting shall be elected from those present by the Noteholders and proxies entitled to vote by more than 50% of the aggregate principal amount of the Notes represented at the meeting. The Trustee, if represented at the meeting, shall appoint two Inspectors of Votes (the "INSPECTORS OF VOTES") who shall count all votes cast at such meeting, except votes on the election of a Chairman and Secretary as aforesaid, and who shall make and file with the Secretary of the meeting their verified written report in duplicate of all such votes to cast at said meeting. If the Trustee shall not be represented at the meeting or shall fail to nominate such Inspectors of Votes or if either Inspector of Votes fails to attend the meeting, the vacancy shall be filled by appointment by the temporary Chairman of the meeting. The Company shall deliver to the Inspectors of Votes, after their designation and prior to any vote of Noteholders which may be taken at such meeting upon any resolution providing for a modification or alteration of this Indenture or any Indenture Supplemental hereto or of the rights or obligations of the Company or of the Holders of the Notes, an Officers' Certificate stating the aggregate principal amount of Notes owned or held by, for the account of or for the benefit or interest of, the Company or any Affiliate of the Company (whether held in the treasury of the 58 Company or any such Affiliate or pledged to secure any indebtedness) and identifying such Notes by serial number or otherwise.

The Holders (or Persons entitled to vote the same) of not less than 51% of the aggregate principal amount of the Notes at the time Outstanding entitled to be voted at any such meeting must be present at such meeting in person or by proxy in order to constitute a quorum for the transaction of business, less than a quorum, however, having power to adjourn. If such meeting is adjourned by less than a quorum for more than seven days, notice thereof shall forthwith be mailed by the Trustee, if such meeting shall have been called by the Trustee, to the persons specified in (S) 12.02(a) and (S) 12.02(b). The failure to mail such notice as aforesaid shall in no case affect the validity of any action taken at any meeting held pursuant to such adjournment. (S) 12.06. MODIFICATIONS OF INDENTURE. Any modifications or alterations of this Indenture, of any Indenture Supplemental hereto, and of the rights and obligations of the Company and of the Holders of the Notes may be made at a meeting of Noteholders duly convened and held in accordance with the provisions of this Article Eleven, but only by a resolution duly adopted by the affirmative vote, in person or by proxy, of the Holders (or persons entitled to vote the same) of at least 51% of the aggregate principal amount of the 1997 Notes at the time Outstanding and the Required Holder(s) of each other series of Notes at the time Outstanding and in each case entitled to be voted upon any such modification or alteration when such meeting is held and approved by resolution of the Board of Directors as hereinafter specified; but no such modification or alteration shall be made, without the consent of the Holder of any Note Outstanding hereunder, which will (a) impair or affect the right of such Holder to receive payment of the principal of (and Yield-Maintenance Amount, if any) and interest on such Note or to institute suit for the enforcement of any such payment, or (b) reduce the percentage of the principal amount of Notes required for the authorization of any such modification or alteration; nor shall any modification or alteration be made which will affect the time, amount or allocation of any prepayments or redemption payments with respect to any of the 1997 Notes or any other series of Notes Outstanding hereunder without the affirmative vote, in person or by proxy, of all Holders of 1997 Notes at the time Outstanding or all Holders of such other series of Notes (or persons entitled to vote the same) at the time Outstanding, as applicable; nor shall any action permitted under this (S) 12.06 and taken at any meeting of the Noteholders affect the rights under this Indenture or under any Indenture Supplemental hereto of the Holders of the 1997 Notes or of one or more, but less than all, of the other series of Notes Outstanding hereunder, unless such action shall have received the affirmative vote, in person or by proxy, of the Holder(s) of not less than 51% in aggregate principal amount of 1997 Notes then outstanding (or persons entitled to vote the same), if so effected, and the Required Holder(s) (or persons entitled to vote the same) of the Notes at the time Outstanding of each other series so affected, in each case entitled to be voted upon any such action when such meeting is held. For all purposes of this Article Twelve, the Trustee shall be entitled to rely upon an opinion of Counsel with respect to the extent, if any, as to which any action taken at such meeting affects the rights under this Indenture or under any Indenture Supplemental hereto of any Holders of Notes then Outstanding. 59 (S) 12.07.

A true copy of any resolution adopted by such meeting shall be mailed by the Trustee to the Noteholders (but failure to mail copies of such resolution as aforesaid shall not affect the validity thereof). Proof of such publication and mailing by the affidavit or affidavits of some person or persons having knowledge of the facts shall be filed with the Trustee. No such Noteholders' resolution shall be binding unless approved by the Board of Directors as evidenced by a Certified Resolution filed with the Trustee, and any resolution of Noteholders so adopted and approved by the Board of Directors shall be deemed conclusively to be binding upon the Company, the Trustee and the Holders of all Notes, except as otherwise specifically provided in this Article Twelve; provided, that no such resolution of the Noteholders, or of the Board of Directors, shall in any manner be so construed as to change or modify any of the rights or obligations of the Trustee without its written assent thereto. Nothing in this Article Twelve contained shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Noteholders or of any right expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Noteholders under any of the provisions of this Indenture or of the Notes.

(S) 12.09. ENDORSEMENT OF NEW NOTES. Notes authenticated and delivered after the date of any Noteholders' meeting or consent may bear a notation, in form approved by the Trustee, as to the action taken and, in such case, upon demand of the Holder of any Note Outstanding at the date of any such meeting and presentation of such Holder's Note for the purpose at the principal corporate trust office of the Trustee, the Company shall cause suitable notation to be made on such Note by endorsement or otherwise as to any action taken at any meeting of Noteholders theretofore 60 held or in any consent theretofore given. If the Company or the Trustee shall so determine, new Notes so modified that they will, in the opinion of the Trustee and the Board of Directors, conform to such Noteholders' resolutions, shall be prepared, authenticated and delivered, and such new Notes shall be exchanged for Notes of the same series and maturity then Outstanding hereunder, upon demand of, and without cost to, the Holders thereof, upon surrender of such Notes. The Company or the Trustee may require Notes to be presented for notation or exchange as aforesaid if either shall see fit to do so. Instruments supplemental to this Indenture embodying any modification or alteration of his Indenture or of any Indenture Supplemental hereto, or of the rights and obligations of the Company or of the Holders of the Notes at any Noteholders' meeting approved by resolution of the Board of Directors as aforesaid, may be executed by the Trustee and the Company; and upon demand of the Trustee, or if so specified in any resolution adopted by any such Noteholders' meeting, shall be executed by the Company and the Trustee.
