Upon request by a Holder of Definitive Debentures and such Holder's compliance with the provisions of this Section 2.06(e), the Registrar shall register the transfer or exchange of Definitive Debentures. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Registrar the Definitive Debentures duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder shall provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section 2.06(e). (i) RESTRICTED DEFINITIVE DEBENTURES TO RESTRICTED DEFINITIVE DEBENTURES. Any Restricted Definitive Debenture may be transferred to and registered in the name of Persons who take delivery thereof in the form of a Restricted Definitive Debenture if the Registrar receives the following: (A) if the transfer will be made pursuant to Rule 144A under the Securities Act, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; (B) if the transfer will be made pursuant to Rule 903 or Rule 904, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof; and (C) if the transfer will be made pursuant to any other exemption from the registration requirements of the Securities Act, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications, certificates and Opinion of Counsel required by item (3) thereof, if applicable. (ii) RESTRICTED DEFINITIVE DEBENTURES TO UNRESTRICTED DEFINITIVE DEBENTURES. Any Restricted Definitive Debenture may be exchanged by the 37 Holder thereof for an Unrestricted Definitive Debenture or transferred to a Person or Persons who take delivery thereof in the form of an Unrestricted Definitive Debenture if: (A) such exchange or transfer is effected pursuant to the Exchange Offer in accordance with the Registration Rights Agreement and the Holder, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable Letter of Transmittal that it is not (1) a Broker-Dealer, (2) a Person participating in the distribution of the Exchange Debentures or (3) a Person who is an affiliate (as defined in Rule 144) of the Company; (B) any such transfer is effected pursuant to the Shelf Registration Statement in accordance with the Registration Rights Agreement; (C) any such transfer is effected by a Broker-Dealer pursuant to the Exchange Offer Registration Statement in accordance with the Registration Rights Agreement; or (D) the Registrar receives the following: (1) if the Holder of such Restricted Definitive Debentures proposes to exchange such Debentures for an Unrestricted Definitive Debenture, a certificate from such Holder in the form of Exhibit C hereto, including the certifications in item (1)(d) thereof; or (2) if the Holder of such Restricted Definitive Debentures proposes to transfer such Debentures to a Person who shall take delivery thereof in the form of an Unrestricted Definitive Debenture, a certificate from such Holder in the form of Exhibit B hereto, including the certifications in item (4) thereof; and, in each such case set forth in this subparagraph (D), an Opinion of Counsel in form reasonably acceptable to the Registrar and the Company to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act. (iii) UNRESTRICTED DEFINITIVE DEBENTURES TO UNRESTRICTED DEFINITIVE DEBENTURES. A Holder of Unrestricted Definitive Debentures may transfer such Debentures to a Person who takes delivery thereof in the form of an Unrestricted Definitive Debenture. Upon receipt of a request to register such a transfer, the Registrar shall register the Unrestricted Definitive Debentures pursuant to the instructions from the Holder thereof. (f) EXCHANGE OFFER. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate (i) one or more Unrestricted Global Debentures in an aggregate principal amount equal to the sum of (A) the principal amount of the beneficial interests in the 38 Restricted Global Debentures tendered for acceptance by Persons that certify in the applicable Letters of Transmittal that (x) they are not Broker-Dealers, (y) they are not participating in a distribution of the Exchange Debentures and (z) they are not affiliates (as defined in Rule 144) of the Company, and accepted for exchange in the Exchange Offer and (B) the principal amount of Definitive Debentures exchanged or transferred for beneficial interests in Unrestricted Global Debentures in connection with the Exchange Offer pursuant to Section 2.06(d)(ii) and (ii) Definitive Debentures in an aggregate principal amount equal to the principal amount of the Restricted Definitive Debentures accepted for exchange in the Exchange Offer (other than Definitive Debentures described in clause (i)(B) immediately above). Concurrently with the issuance of such Debentures, the Trustee shall cause the aggregate principal amount of the applicable Restricted Global Debentures to be reduced accordingly, and the Company shall execute and, upon receipt of an Authentication Order pursuant to Section 2.02, the Trustee shall authenticate and deliver to the Persons designated by the Holders of Definitive Debentures so accepted Definitive Debentures in the appropriate principal amount. (g) LEGENDS. The following legends shall appear on the face of all Global Debentures and Definitive Debentures issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture. (i) PRIVATE PLACEMENT LEGEND. (A) Except as permitted by subparagraph (B) below, each Global Debenture and each Definitive Debenture (and all Debentures issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form: THIS DEBENTURE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS, EXCEPT AS SET FORTH IN THE NEXT SENTENCE.

To the extent required by the Depositary, each Global Debenture shall bear a legend in substantially the following form: 40 THIS GLOBAL DEBENTURE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS DEBENTURE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (II) THIS GLOBAL DEBENTURE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (III) THIS GLOBAL DEBENTURE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL DEBENTURE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER. (h) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL DEBENTURES. At such time as all beneficial interests in a particular Global Debenture have been exchanged for Definitive Debentures or a particular Global Debenture has been redeemed, repurchased or cancelled in whole and not in part, each such Global Debenture shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Debenture is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Debenture or for Definitive Debentures, the principal amount of Debentures represented by such Global Debenture shall be reduced accordingly and an endorsement shall be made on such Global Debenture by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Debenture, such other Global Debenture shall be increased accordingly and an endorsement shall be made on such Global Debenture by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. (i) GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES. (i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Debentures and Definitive Debentures upon receipt of an Authentication Order. (ii) No service charge shall be made to a holder of a beneficial interest in a Global Debenture or to a Holder of a Definitive Debenture for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection 41 therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 4.13 and 4.14 hereof). (iii) The Registrar shall not be required to register the transfer of or exchange any Debenture selected for redemption in whole or in part, except the unredeemed portion of any Debenture being redeemed in part. (iv) All Global Debentures and Definitive Debentures issued upon any registration of transfer or exchange of Global Debentures or Definitive Debentures shall be the valid obligations of the Company, evidencing the same Indebtedness, and entitled to the same benefits under this Indenture, as the Global Debentures or Definitive Debentures surrendered upon such registration of transfer or exchange. (v) The Company shall not be required (A) to issue, to register the transfer of or to exchange any Debentures during a period beginning at the opening of business 15 days before the day of any selection of Debentures for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Debenture so selected for redemption in whole or in part, except the unredeemed portion of any Debenture being redeemed in part or (C) to register the transfer of or to exchange a Debenture between a record date and the next succeeding interest payment date. (vi) Prior to due presentment for the registration of a transfer of any Debenture, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Debenture is registered as the absolute owner of such Debenture for the purpose of receiving payment of principal of and interest on such Debentures and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. (vii) The Trustee shall authenticate Global Debentures and Definitive Debentures in accordance with the provisions of Section 2.02 hereof. (viii) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. SECTION 2.07. REPLACEMENT DEBENTURES If any mutilated Debenture is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Debenture, the Company shall issue and the Trustee, upon receipt of an Authentication 42 Order, shall authenticate a replacement Debenture if the Trustee's requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Debenture is replaced. The Company may charge for its expenses in replacing a Debenture. Every replacement Debenture is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Debentures duly issued hereunder. SECTION 2.08. OUTSTANDING DEBENTURES The Debentures outstanding at any time are all the Debentures authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Debenture effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Debenture does not cease to be outstanding because the Company or an Affiliate of the Company holds the Debenture. If a Debenture is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Debenture is held by a bona fide purchaser. If the principal amount of any Debenture is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or the maturity date, money sufficient to pay Debentures payable on that date, then on and after that date such Debentures shall be deemed to be no longer outstanding and shall cease to accrue interest. SECTION 2.09. TREASURY DEBENTURES In determining whether the Holders of the required principal amount of Debentures have concurred in any direction, waiver or consent, Debentures owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Debentures that the Trustee knows are so owned shall be so disregarded. SECTION 2.10. TEMPORARY DEBENTURES Until certificates representing Debentures are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Debentures. Temporary Debentures shall be substantially in the 43 form of certificated Debentures but may have variations that the Company considers appropriate for temporary Debentures and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Debentures in exchange for temporary Debentures. Holders of temporary Debentures shall be entitled to all of the benefits of this Indenture. SECTION 2.11. CANCELLATION The Company at any time may deliver Debentures to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Debentures surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Debentures surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Debentures (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Debentures shall be delivered to the Company. The Company may not issue new Debentures to replace Debentures that it has paid or that have been delivered to the Trustee for cancellation. SECTION 2.12. DEFAULTED INTEREST If the Company defaults in a payment of interest on the Debentures, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Debentures and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Debenture and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date; PROVIDED that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 44 ARTICLE 3. REDEMPTION SECTION 3.01. NOTICES TO TRUSTEE If the Company elects to redeem Debentures pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 45 days (unless a shorter period is acceptable to the Trustee) but not more than 60 days before a redemption date, an Officers' Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Debentures to be redeemed and (iv) the redemption price. SECTION 3.02. SELECTION OF DEBENTURES TO BE REDEEMED If less than all of the Debentures are to be redeemed at any time, the Trustee shall select the Debentures to be redeemed among the Holders of the Debentures in compliance with the requirements of the principal national securities exchange, if any, on which the Debentures are listed or, if the Debentures are not so listed, on a PRO RATA basis, by lot or in accordance with any other method the Trustee considers fair and appropriate. In the event of partial redemption by lot, the particular Debentures to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Debentures not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Debentures selected for redemption and, in the case of any Debenture selected for partial redemption, the principal amount thereof to be redeemed. Debentures and portions of Debentures selected shall be in amounts of $1,000 or integral multiples of $1,000; except that if all of the Debentures of a Holder are to be redeemed, the entire outstanding amount of Debentures held by such Holder, even if not an integral multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Debentures called for redemption also apply to portions of Debentures called for redemption. SECTION 3.03. NOTICE OF REDEMPTION At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Debentures are to be redeemed at its registered address. 45 The notice shall identify the Debentures to be redeemed and shall state: (a) the redemption date; (b) the redemption price; (c) if any Debenture is being redeemed in part, the portion of the principal amount at maturity of such Debenture to be redeemed and that, after the redemption date upon surrender of such Debenture, a new Debenture or Debentures in principal amount at maturity equal to the unredeemed portion shall be issued upon cancellation of the original Debenture; (d) the name and address of the Paying Agent; (e) that Debentures called for redemption must be surrendered to the Paying Agent to collect the redemption price; (f) that, unless the Company defaults in making such redemption payment, interest on Debentures called for redemption ceases to accrue and Accreted Value ceases to increase on and after the redemption date; (g) the paragraph of the Debentures and/or Section of this Indenture pursuant to which the Debentures called for redemption are being redeemed; and (h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Debentures. At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION Once notice of redemption is mailed in accordance with Section 3.03 hereof, Debentures called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 46 SECTION 3.05. DEPOSIT OF REDEMPTION PRICE On the Business Day immediately prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent immediately available funds sufficient to pay the redemption price of and accrued interest on all Debentures to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Debentures to be redeemed. If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Debentures or the portions of Debentures called for redemption. If a Debenture is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Debenture was registered at the close of business on such record date. If any Debenture called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Debentures and in Section 4.01 hereof. SECTION 3.06. DEBENTURES REDEEMED IN PART Upon surrender of a Debenture that is redeemed in part, the Company shall issue and, upon receipt of an Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Company a new Debenture equal in principal amount to the unredeemed portion of the Debenture surrendered. SECTION 3.07. OPTIONAL REDEMPTION The Debentures will be redeemable, at the Company's option, in whole or in part, at any time or from time to time, on or after May 15, 2003 and prior to maturity, upon not less than 30 nor more than 60 days' prior notice mailed by first class mail to each Holder's last registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest and Liquidated Damages, if any, to the redemption date, if redeemed during the 12-month period commencing May 15, of the years set forth below: 47 YEAR PERCENTAGE 2003 . . . . . . . . . . . . . . . . . . . . . 106.563% 2004 . . . . . . . . . . . . . . . . . . . . . 104.375% 2005 . . . . . . . . . . . . . . . . . . . . . 102.188% 2006 and thereafter . . . . . . . . . . . . . . 100.000% In addition, at any time or from time to time on or prior to May 15, 2001, the Company may redeem up to 35% of the principal amount at maturity of the Debentures at a redemption price (expressed as a percentage of Accreted Value) of 113.125%, plus accrued and unpaid interest and Liquidated Damages, if any, to the redemption date with the Net Cash Proceeds of one or more Equity Offerings; PROVIDED that at least 65% of the aggregate principal amount at maturity of Debentures remains outstanding after the occurrence of each such redemption; and PROVIDED FURTHER, that such redemption occurs within 90 days of the date of the closing of such Equity Offering. SECTION 3.08. NO MANDATORY REDEMPTION The Company shall not be required to make mandatory redemption payments with respect to the Debentures. ARTICLE 4. COVENANTS SECTION 4.01. PAYMENT OF DEBENTURES The Company shall pay or cause to be paid the principal of, premium, if any, and interest on the Debentures on the dates and in the manner provided in the Debentures. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 12:00 noon Eastern time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. The Company shall pay all Liquidated Damages, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement. The Company's Obligations under the Debentures, this Indenture and the Registration Rights Agreement are referred to herein as the "Company Obligations." The Company shall pay interest (including Accrued Bankruptcy Interest in any proceeding under any Bankruptcy Law) on overdue principal at the then applicable interest rate on the Debentures to the extent lawful; it shall pay interest (including Accrued Bankruptcy Interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages (without regard to any applicable grace period) at the same rate to the extent lawful. 48 SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY The Company shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Debentures may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Debentures and this Indenture may be served. 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 or served at the Corporate Trust Office. The Company may also from time to time designate one or more other offices or agencies where the Debentures may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. 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 the Corporate Trust Office as one such office or agency of the Company in accordance with Section 2.03 hereof. SECTION 4.03. SEC REPORTS AND REPORTS TO HOLDERS Whether or not required by the rules and regulations of the SEC, so long as any Debentures are outstanding, beginning with the year ending December 31, 1998, the Company shall furnish to the Holders of Debentures and the Trustee (i) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report thereon by the Company's certified independent accountants and (ii) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports; PROVIDED that the foregoing shall not require the Company to furnish separate financial results of its Subsidiaries. In addition, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability (unless the SEC will not accept such a filing) and make such information available to securities analysts and prospective investors upon request. In addition, for so long as any Debentures remain outstanding, the Company shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 49 SECTION 4.04.

SECTION 4.05. TAXES The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment would not have a material adverse effect on the ability of the Company to satisfy its obligations under the Debentures and this Indenture. SECTION 4.06. STAY, EXTENSION AND USURY LAWS The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the 50 Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

(vii) the incurrence by the Company or any of its Subsidiaries of intercompany Indebtedness between or among the Company and any of its Subsidiaries or between or among any of its Subsidiaries; PROVIDED, HOWEVER, that (x) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Subsidiary of the Company and (y) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Subsidiary of the Company will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Subsidiary, as the case may be;

Indebtedness or Disqualified Stock of any Person which is outstanding at the time such Person becomes a Subsidiary of the Company (including upon designation of any subsidiary or other person as a Subsidiary) or is merged with or into or consolidated with the Company or a Subsidiary of the Company shall be deemed to have been incurred at the time such Person becomes a Subsidiary of the Company or is merged with or consolidated with the Company or a Subsidiary of the Company, as applicable.

The Board of Directors may designate any Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default or Event of Default. For purposes of making such determination, all outstanding Investments by the Company and its Subsidiaries (except to the extent repaid in cash or Cash Equivalents) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of this Section 4.09. All such outstanding Investments shall be deemed to constitute Investments in an amount equal to the greatest of (x) the net book value of such Investments at the time of such designation, (y) the fair market value of such Investments at the time of such designation and (z) the original fair market value of such Investments at the time they were made. Such designation shall only be permitted if such Restricted Payment would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 57 The amount of all Restricted Payments (other than cash or Cash Equivalents) shall be the fair market value (as and to the extent set forth in an Officers' Certificate delivered to the Trustee pursuant to the next sentence) on the date of the Restricted Payment of the asset(s) proposed to be transferred by the Company or such Subsidiary, as the case may be, pursuant to the Restricted Payment. Not later than five Business Days following the date of making any Restricted Payment in excess of $1,000,000, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section were computed, which calculations may be based upon the Company's latest available financial statements.

refundings, replacements or refinancings thereof, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more

on the Issue Date, (d) this Indenture and the 58 Debentures or any Indebtedness ranking on a PARI PASSU basis with the Debentures, provided such restrictions are no more restrictive, taken as a whole,

effect at the time of such acquisition (except to the extent such Acquired Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is

SECTION 4.11. LIMITATION ON LINES OF BUSINESS Neither the Company nor any of its Subsidiaries shall directly or indirectly engage to any substantial extent in any line or lines of business activity other 59 than that which, in the reasonable good faith judgment of the Board of Directors of the Company, is a Related Business.

In addition, none of the Acquisition Transactions shall be deemed to be Affiliate Transactions. SECTION 4.13. LIMITATION ON ASSET SALES The Company shall not, and shall not permit any of its Subsidiaries to, engage in an Asset Sale in excess of $1,000,000 unless (i) the Company (or the Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity Interests sold or otherwise disposed of, and in the case of a lease of assets, a lease providing for rent and other conditions which are no less favorable to the Company (or the Subsidiary, as the case may be) in any material respect than the then prevailing market conditions (in each case 60 as set forth in an Officers' Certificate delivered to the Trustee), (ii) at least 75% of the consideration therefor received by the Company or such Subsidiary is in the form of cash or Cash Equivalents; PROVIDED that the amount of (x) any liabilities (as shown on the Company's or such Subsidiary's most recent balance sheet or in the notes thereto, excluding contingent liabilities and trade payables) of the Company or any Subsidiary (other than liabilities that are by their terms subordinated to, or PARI PASSU with, the Debentures) that are assumed by the transferee of any such assets and (y) any notes or other obligations received by the Company or any such Subsidiary from such transferee that are promptly, but in no event more than 30 days after receipt, converted by the Company or such Subsidiary into cash (to the extent of the cash received), will be deemed to be cash for purposes of this provision and the receipt of such cash shall be treated as cash received from an Asset Sale for which such Debentures or obligations were received. The Company or any of its Subsidiaries may apply the Net Proceeds from each Asset Sale, at its option, within 415 days after the consummation of such Asset Sale, (a) to permanently reduce any Indebtedness (and in the case of any revolving indebtedness to correspondingly permanently reduce commitments with respect thereto) of the Company or a Subsidiary of the Company, or (b) for the acquisition of another business or the acquisition of other property or assets, in each case, in the same or a Related Business or (c) for any combination of the foregoing. Pending the final application of any such Net Proceeds, the Company may temporarily reduce Indebtedness of a Subsidiary of the Company or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $5,000,000, the Company will be required to make an offer to all Holders of Debentures (an "Asset Sale Offer") and to holders of other Indebtedness of the Company outstanding ranking on a PARI PASSU basis with the Debentures with provisions requiring the Company to make an offer (or otherwise redeem or prepay) with proceeds from the Asset Sales, PRO RATA in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Debentures and such other Indebtedness then outstanding, to purchase (or otherwise redeem or prepay) the maximum principal amount (or Accreted Value, as applicable) of Debentures and such other Indebtedness, if any, that may be purchased (or redeemed or prepaid) out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or Accreted Value, if the date of repurchase is prior to May 15, 2003) thereof plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of purchase, in accordance with the procedures set forth in this Section. If the aggregate principal amount (or Accreted Value, as applicable) of Debentures and such Indebtedness surrendered by Holders thereof exceeds the amount of Excess Proceeds, the 61 Trustee shall select the Debentures and such Indebtedness to be purchased on a PRO RATA basis. Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. The Asset Sale Offer will remain open for a period not to exceed 30 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the "Asset Sale Offer Period"). No later than five Business Days after the termination of the Asset Sale Offer Period (the "Asset Sale Purchase Date"), the Company will purchase the principal amount of Debentures required to be purchased pursuant to this covenant (the "Asset Sale Offer Amount") or, if less than the Asset Sale Offer Amount has been tendered, all Debentures tendered in response to the Asset Sale Offer. Payment for any Debentures so purchased will be made in the same manner as interest payments are made. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations were applicable in connection with the repurchase of the Debentures as a result of an Asset Sale Offer. To the extent the provisions of any such securities laws or regulations conflict with the provisions of this covenant, compliance by the Company with such laws, rules and regulations shall not in and of itself cause a breach of its obligations under this covenant. If the Asset Sale Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Debenture is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Debentures pursuant to the Asset Sale Offer. Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders to tender Debentures pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders.

ACCELERATION If an Event of Default (other than an Event of Default specified in clause (h) or (i) of Section 6.01 that occurs with respect to the Company) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount at maturity of the Debentures, then outstanding, by written notice to the Company (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of (if on or after May 15, 2003, or Accreted Value thereof if prior to May 15, 2003), premium, if any, and accrued interest (including Liquidated Damages) on the Debentures to be immediately due and payable. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest shall be immediately due and payable; PROVIDED that such acceleration shall automatically be rescinded and annulled without any further action required on the part of the Holders in the event that any and all Events of Default specified in the acceleration notice under this Indenture shall have been cured, waived or otherwise remedied as provided in this Indenture. In the event of a declaration of acceleration because an Event of Default set forth in clause (f) above has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the default triggering such Event of Default pursuant to clause (f) shall be remedied or cured by the Company or the relevant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto. If an Event of Default specified in clause (h) or (i) above occurs with respect to the Company, the principal of (if on or after May 15, 2003, or Accreted Value thereof if prior to May 15, 2003), premium, if any, and accrued interest on the Debentures then outstanding shall IPSO FACTO become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. SECTION 6.03. OTHER REMEDIES If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Debentures or to enforce the performance of any provision of the Debentures or this Indenture. 67 The Trustee may maintain a proceeding even if it does not possess any of the Debentures or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Debenture in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 6.04. WAIVER OF PAST DEFAULTS The Holders of at least a majority in principal amount at maturity of the outstanding Debentures by written notice to the Company and to the Trustee, may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Debentures that have become due solely by such declaration of acceleration, have been cured or waived and (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. SECTION 6.05. CONTROL BY MAJORITY Holders of at least a majority in aggregate principal amount at maturity of the then outstanding Debentures 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. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines in good faith may be unduly prejudicial to the rights of other Holders of Debentures not joining in the giving of such direction or that may involve the Trustee in personal liability and the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from Holders of the Debentures. SECTION 6.06. LIMITATION ON SUITS A Holder of a Debenture may pursue a remedy with respect to this Indenture or the Debentures only if: (a) the Holder of a Debenture gives to the Trustee written notice of a continuing Event of Default; 68 (b) the Holders of at least 25% in aggregate principal amount at maturity of the then outstanding Debentures make a written request to the Trustee to pursue the remedy; (c) such Holder of a Debenture or Holders of Debentures offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any costs, 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 at maturity of the then outstanding Debentures do not give the Trustee a direction inconsistent with the request. A Holder of a Debenture may not use this Indenture to prejudice the rights of another Holder of a Debenture or to obtain a preference or priority over another Holder of a Debenture. SECTION 6.07. RIGHTS OF HOLDERS OF DEBENTURES TO RECEIVE PAYMENT Notwithstanding any other provision of this Indenture, the right of any Holder of a Debenture to receive payment of the principal of, premium and Liquidated Damages, if any, and interest on the Debenture, on or after the respective due dates expressed in the Debenture (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. COLLECTION SUIT BY TRUSTEE If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Liquidated Damages, if any, and interest remaining unpaid on the Debentures 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. 69 SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Debentures allowed in any judicial proceedings relative to the Company (or any other obligor upon the Debentures), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, 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 Debentures or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. PRIORITIES If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; SECOND: to Holders of Debentures for amounts due and unpaid on the Debentures for principal and Liquidated Damages, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Debentures for principal, premium and Liquidated Damages, if any, and interest, respectively; and 70 THIRD: to the Company or to such party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders of Debentures 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, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Debenture pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount at maturity of the then outstanding Debentures. ARTICLE 7. TRUSTEE SECTION 7.01. DUTIES OF TRUSTEE (a) If an Event of Default has occurred and is continuing, the Trustee shall 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 man would exercise or use under the circumstances in the conduct of his own affairs.

However, the Trustee shall examine the certificates 71 and opinions to determine whether or not they conform to the requirements of this Indenture. (c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this paragraph (c) does not limit the effect of paragraph (b) of this Section; (ii) the Trustee shall not be liable for any error of judgment made in good faith by an Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to Sections 7.01 and 7.02. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. (g) Except with respect to Section 4.01 hereof, the Trustee shall have no duty to inquire as to the performance of the Company's covenants in Article 4 hereof.

INDIVIDUAL RIGHTS OF TRUSTEE The Trustee in its individual or any other capacity may become the owner or pledgee of Debentures and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. SECTION 7.04. TRUSTEE'S DISCLAIMER The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Debentures, it shall not be accountable for the Company's use of the proceeds from the Debentures or any money paid to the Company or upon the Company's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Debentures or any other document in connection with the sale of the Debentures or pursuant to this Indenture other than its certificate of authentication. SECTION 7.05. NOTICE OF DEFAULTS If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Debentures in the manner and to the extent provided by Section 313(c) of the TIA a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Debenture, the Trustee may withhold the notice if and so long as a committee of its Officers in good faith determines that withholding the notice is in the interests of the Holders of the Debentures. SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE DEBENTURES Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Debentures remain outstanding, the Trustee shall mail to the Holders of the Debentures a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). 74 A copy of each such report at the time of its mailing to the Holders of Debentures shall be mailed to the Company and filed with the SEC and each stock exchange on which the Debentures are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Debentures are listed on any stock exchange. SECTION 7.07. COMPENSATION AND INDEMNITY The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder.

Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company shall indemnify the Trustee against any and all losses, liabilities or expenses (including reasonable attorneys' fees) 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, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its 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 its consent, which consent shall not be unreasonably withheld.

To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Debentures on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Debentures. Such Lien shall survive the satisfaction and discharge of this Indenture. 75 When the Trustee incurs expenses or renders services after an Event of Default specified in Sections 6.01(h) or 6.01(i) hereof 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 Section 313(b)(2) to the extent applicable. SECTION 7.08. REPLACEMENT OF TRUSTEE A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Debentures of a majority in principal amount at maturity of the then outstanding Debentures 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 hereof; (b) the Trustee is adjudged a bankrupt or an 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. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount at maturity of the then outstanding Debentures 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 Debentures of at least 10% in principal amount at maturity of the then outstanding Debentures may petition any court of competent jurisdiction for the appointment of a successor Trustee. 76 If the Trustee, after written request by any Holder of a Debenture who has been a Holder of a Debenture for at least six months, fails to comply with Section 7.10, such Holder of a Debenture may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders of the Debentures. 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 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. SECTION 7.10. ELIGIBILITY; DISQUALIFICATION There shall at all times be a Trustee hereunder that is a corporation (or a member of a bank holding company) organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has (or the bank holding company of which it is a member has) a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b). SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 77 ARTICLE 8. LEGAL DEFEASANCE AND COVENANT DEFEASANCE SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Debentures upon compliance with the conditions set forth below in this Article 8. SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Debentures on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Debentures, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Debentures and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Debentures to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest and Liquidated Damages, if any, on such Debentures when such payments are due, (b) the Company's obligations with respect to such Debentures under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith and (d) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. SECTION 8.03. COVENANT DEFEASANCE Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, the Company be released from its obligations under Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13 and 4.14 hereof, in each case on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Debentures shall thereafter be deemed not "outstanding" for the 78 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 Debentures shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Debentures, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Debentures shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, (x) Sections 6.01(c) through 6.01(g) hereof shall not constitute Events of Default and (y) Sections 6.01(h) and 6.01(i) shall not constitute Events of Default as of the 91st day following the occurrence of Covenant Defeasance. SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Debentures: In order to exercise either Legal Defeasance or Covenant Defeasance: (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium and Liquidated Damages, if any, and interest on the outstanding Debentures on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Debentures are being defeased to maturity or to a particular redemption date; (b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Debentures will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be 79 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; (c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Debentures 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; (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Debentures pursuant to this Article 8 concurrently with such incurrence); (e) such Legal Defeasance or Covenant Defeasance shall 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 Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; (f) the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company; and (g) the Company shall have delivered to the Trustee an Officers' Certificate stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. Legal Defeasance and Covenant Defeasance shall be deemed to occur on the date of the deposit required under Section 8.04(a), so long as all of the other conditions set forth in Section 8.04 are satisfied as of such date. SECTION 8.05. DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS Subject to Section 8.06 hereof, 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 hereof in respect of the outstanding Debentures shall be held in trust and applied by the Trustee, in accordance with the provisions of such Debentures and this 80 Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Debentures 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 hereof or the principal and interest received in respect thereof. Anything in this Article 8 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 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. SECTION 8.06. REPAYMENT TO COMPANY Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, Liquidated Damages or interest on any Debenture and remaining unclaimed for two years after such principal, and premium, if any, Liquidated Damages, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Debenture shall thereafter, as a creditor, 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 will 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 81 hereof, 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 Debentures shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof 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 hereof, as the case may be; PROVIDED, HOWEVER, that, if the Company makes any payment of principal of, premium, if any, or interest on any Debenture following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Debentures to receive such payment from the money held by the Trustee or Paying Agent. ARTICLE 9. AMENDMENT, SUPPLEMENT AND WAIVER SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF DEBENTURES Notwithstanding Section 9.02 of this Indenture, the Company and the Trustee may amend or supplement this Indenture or the Debentures without the consent of any Holder of a Debenture: (a) to cure any ambiguity, defect or inconsistency; (b) to provide for uncertificated Debentures in addition to or in place of certificated Debentures; (c) to provide for the assumption of the Company's obligations to the Holders of the Debentures in the case of a merger or consolidation pursuant to Article 5 hereof; (d) to make any change that would provide any additional rights or benefits to the Holders of the Debentures or that does not adversely affect the legal rights hereunder of any Holder of the Debenture; (e) to comply with the provisions of the Depositary, Euroclear or Cedel or the Trustee with respect to the provisions of this Indenture or the Debentures relating to transfers and exchanges of Debentures or beneficial interests therein; or (f) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. 82 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that adversely affects its own rights, duties or immunities under this Indenture or otherwise. SECTION 9.02. WITH CONSENT OF HOLDERS OF DEBENTURES Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Sections 4.13 and 4.14 hereof), and the Debentures with the consent of the Holders of a majority in aggregate principal amount of the Debentures then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Debentures), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Debentures, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Debentures may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Debentures (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Debentures). In connection with any amendment, supplement or waiver under this Article 9, the Company may, but shall not be obligated to, offer to any Holder who consents to such amendment, supplement or waiver, or to all Holders, consideration for such Holder's consent to such amendment, supplement or waiver. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Debentures as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture adversely 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. 83 It shall not be necessary for the consent of the Holders of Debentures 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 becomes effective, the Company shall mail to the Holders of Debentures affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Debentures then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Debentures. However, without the consent of each Holder affected (it being understood that Sections 4.13 and 4.14 hereof may be amended in accordance with the first paragraph of this Section 9.02), an amendment or waiver may not (with respect to any Debentures held by a non-consenting Holder): (a) reduce the principal amount of Debentures whose Holders must consent to an amendment, supplement or waiver; (b) reduce the principal of or change the final stated maturity of any Debenture or alter or waive any of the provisions with respect to the redemption of the Debentures under Section 3.07; (c) reduce the rate of or change the time for payment of interest, including default interest, on any Debenture; (d) waive a past Default or past Event of Default in the payment of principal of or premium, if any, or interest on the Debentures (except a rescission of acceleration of the Debentures by the Holders of a majority in aggregate principal amount of the then outstanding Debentures and a waiver of the payment default that resulted from such acceleration); (e) make any Debenture payable in money other than that stated in the Debentures; (f) except as otherwise provided in this fifth paragraph of Section 9.02 (including clauses (a) through (g) hereof), make any change in the provisions of this Indenture, the Debentures relating to waivers of past Defaults or Events of Default or the rights of Holders of Debentures to receive payments of principal of, premium or Liquidated Damages, if any, or interest on the Debentures; or 84 (g) make any change in the foregoing amendment and waiver provisions. SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT Every amendment or supplement to this Indenture or the Debentures shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS Until an amendment, supplement or waiver becomes effective (as determined by the Company), a consent to it by a Holder of a Debenture is a continuing consent by the Holder of a Debenture and every subsequent Holder of a Debenture or portion of a Debenture that evidences the same Indebtedness as the consenting Holder's Debenture, even if notation of the consent is not made on any Debenture. However, any such Holder of a Debenture or subsequent Holder of a Debenture may revoke the consent as to its Debenture if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective (as determined by the Company). 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 DEBENTURES The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Debenture thereafter authenticated. The Company in exchange for all Debentures may issue and the Trustee shall authenticate new Debentures that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Debenture 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 entitled to receive indemnity reasonably satisfactory to it and to receive and (subject to Section 7.01) shall be fully protected in relying upon, an Officer's Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 85 ARTICLE 10. MISCELLANEOUS SECTION 10.01. TRUST INDENTURE ACT CONTROLS If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by the TIA, the imposed duties shall control.

SECTION 10.06. RULES BY TRUSTEE AND AGENTS The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions. SECTION 10.07. NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS No past, present or future director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any Obligations of the Company under the Debentures or this Indenture or for any claim based on, in respect of, or by reason of, such Obligations or their creation. Each Holder by accepting a Debenture waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Debentures. 88 SECTION 10.08.

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $5,000,000, the Company will be required to make an offer to all Holders of Debentures (an "Asset Sale Offer") and to holders of other Indebtedness of the Company outstanding ranking on a PARI PASSU basis with the Debentures with provisions requiring the Company to make an offer (or otherwise redeem or prepay) with proceeds from the Asset Sales, PRO RATA in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an original issue discount) of the Debentures and such other Indebtedness then outstanding, to purchase (or otherwise redeem or prepay) the maximum principal amount (or Accreted Value, as applicable) of Debentures and such other Indebtedness, if any, that may be purchased (or redeemed or prepaid) out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or Accreted Value, if the date of repurchase is prior to May 15, 2003) thereof plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of purchase, in accordance with the procedures set forth in the Indenture.

Upon completion of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. 8. DENOMINATIONS, TRANSFER, EXCHANGE.
