 INDENTURE 
  

INDENTURE dated as of September 30, 2004 among US LEC Corp., a Delaware corporation (the “Issuer”), the Guarantors (as defined
herein), if any, and U.S. Bank National Association, a national banking organization, as trustee (the “Trustee”). 
  
 Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders (as defined below) of the
Issuer’s Second Priority Senior Secured Floating Rate Notes due 2009: 
  
 ARTICLE I 
  
 DEFINITIONS AND
INCORPORATION BY REFERENCE 
  
 SECTION 1.1.
Definitions. 
  
 “Acquired Indebtedness”
means Indebtedness of a Person or any of its Subsidiaries existing at the time such Person becomes a Restricted Subsidiary of the Issuer or at the time it merges or consolidates with or into the Issuer or any of its Subsidiaries or assumed in
connection with the acquisition of assets from such Person and in each case not incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary of the Issuer or such acquisition,
merger or consolidation. 
  
 “Additional
Interest” means all additional interest then owing pursuant to Section 4 of the Registration Rights Agreement. 
  
 “Additional Notes” means Notes, in addition to the $150,000,000 aggregate principal amount of Series A Notes issued on the Issue Date (or
the Series B Notes issued in exchange for the Series A Notes issued on the Issue Date) (together, the “Initial Notes”), issued pursuant to Article II hereof and in compliance with Sections 4.9 and 4.12 hereof that include the
provisions of this Indenture but may have interest and other economic terms different from the Initial Notes. 
  
 “Affiliate” means, with respect to any specified Person, any other Person who directly or indirectly through one or more intermediaries
controls, or is controlled by, or is under common control with, such specified Person. The term “control” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a
Person, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative of the foregoing. A Person shall not be deemed an “Affiliate”
of the Issuer or any of its Restricted Subsidiaries solely as a result of such Person being a joint venture partner of the Issuer or any of its Subsidiaries. 
  
 “Agent” means any Registrar, Paying Agent or co-registrar. 
  
 “Asset Acquisition” means (1) an Investment by the Issuer or any Restricted Subsidiary of the Issuer in any
other Person pursuant to which such Person shall become a Restricted Subsidiary of the Issuer or any Restricted Subsidiary of the Issuer, or shall be merged with or into the Issuer or any Restricted Subsidiary of the Issuer, or (2) the acquisition
by the Issuer or any Restricted Subsidiary of the Issuer of the assets of any Person (other than a Restricted Subsidiary of the Issuer) which constitute all or substantially all of the assets of such Person or comprise any division or line of
business of such Person or any other properties or assets of such Person other than in the ordinary course of business. 







 “Asset Sale” means any direct or indirect sale, issuance, conveyance, transfer, lease
(other than operating leases entered into in the ordinary course of business), assignment or other transfer for value by the Issuer or any of its Restricted Subsidiaries (including any Sale and Leaseback Transaction but excluding any Lien granted in

 -28- 








 Notes for original issue on the Issue Date in the aggregate principal amount not to exceed $150.0 million and (ii)
subject to Section 4.9 hereof, Additional Notes. The Trustee, upon written order of the Issuer signed by two Officers of the Issuer, together with the other documents required by Sections 15.4 and 15.5 hereof, shall authenticate Series B Notes;
provided that such Series B Notes shall be issuable only upon the valid surrender for cancellation of Series A Notes of a like aggregate principal amount in accordance with the Exchange Offer or an exchange offer specified in any registration
rights agreement relating to the Additional Notes. Such written order of the Issuer shall specify the amount of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated. Any Additional Notes shall be part of
the same issue as the Notes being issued on the Issue Date and will vote on all matters as one class with the Notes being issued on the Issue Date, including, without limitation, waivers, amendments, redemptions, Change of Control Offers and Net
Proceeds Offers. For the purposes of this Indenture, except for Section 4.9 hereof, references to the Notes include Additional Notes, if any.

 SECTION 2.3. Registrar and Paying Agent. 
  
 The

York. At the option of the Issuer, payment of interest and Additional Interest may be paid at the Trustee’s corporate office or by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment
by wire transfer of immediately available funds will be required with respect to principal, Redemption Price and Purchase Price of, and interest and Additional Interest (if any) on, all Global Notes and all other Notes the Holders of which shall
have provided wire transfer instructions to the Trustee or the Paying Agent. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term
“Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer shall notify the Trustee in writing of the name and address of any Paying Agent not a party
to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar. The Depositary shall, by acceptance
of a Global Note, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by the Depositary (or its agent), and that ownership of a beneficial interest in the Note shall be
required to be reflected in a book entry.

appoints the Trustee to act as the Registrar and Paying Agent and to act as Note Custodian with respect to the Global Notes, until such time as the Trustee has resigned or a successor has been appointed. 
  
 SECTION 2.4. Paying Agents to Hold Money in Trust.

any, on the Notes, and shall notify the Trustee of any default by the Issuer in making any such payment. 
  

 -29- 








 While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The
Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any money disbursed. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer) shall have no further liability for the
money. If the Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the
Trustee shall serve as Paying Agent for the Notes. 
  
 SECTION 2.5. Holder Lists. 
  
 The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuer shall
furnish or cause the Registrar to furnish to the Trustee at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of the Holders of Notes, and the Issuer shall otherwise comply with TIA § 312(a).

authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
  
 Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency maintained by the Issuer pursuant to Section 4.2 hereof. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder
making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding. 
  
 All Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Issuer and the Registrar, and the Notes shall be duly executed by the Holder thereof or his attorney duly authorized in writing. Except as otherwise provided in this Indenture, and in addition to
the requirements set forth in the legend referred to in Section 2.6(h)(i) hereof, in connection with any transfer of Transfer Restricted Securities any request for transfer shall be accompanied by a certification to the Trustee relating to the
manner of such transfer substantially in the form of Exhibit D hereto.

Global Note or Regulation S Global Note, as the case may be, held on their behalf by the Depositary, or the Trustee as its custodian, or under the Rule 144A Global Note or Regulation S Global Note, as the case may be, and the Depositary may be
treated by the 
  

 -30- 








 Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of Rule 144A Global Note or
Regulation S Global Note, as the case may be, for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any Note. 
  
 Transfers of the Rule 144A Global Note and the Regulation S Global Note shall
be limited to transfers of such Rule 144A Global Note or Regulation S Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Beneficial interests in the Rule 144A Global Note and the Regulation S
Global Note may be transferred in accordance with the applicable rules and procedures of the Depositary and the provisions of this Section 2.6. The registration of transfer and exchange of beneficial interests in the Global Note, which does not
involve the issuance of a Certificated Note, shall be effected through the Depositary, in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. The Trustee shall have
no responsibility or liability for any act or omission of the Depositary. 
  
 At any time at the request of the beneficial holder of an interest in the Rule 144A Global Note or Permanent Regulation S Global Note to obtain a Certificated Note, such beneficial holder shall be entitled to obtain a
Certificated Note upon written request to the Trustee and the Note Custodian in accordance with the standing instructions and procedures existing between the Note Custodian and Depositary for the issuance thereof. Upon receipt of any such request,
the Trustee, or the Note Custodian at the direction of the Trustee, will cause, in accordance with the standing instructions and procedures existing between the Depositary and the Note Custodian, the aggregate principal amount of the Rule 144A
Global Note or Permanent Regulation S Global Note, as appropriate, to be reduced by the principal amount of the Certificated Note issued upon such request to such beneficial holder and, following such reduction, the Issuer will execute and the
Trustee will authenticate and deliver to such beneficial holder (or its nominee) a Certificated Note or Certificated Notes in the appropriate aggregate principal amount in the name of such beneficial holder (or its nominee) and bearing such
restrictive legends as may be required by this Indenture. 
  
 (c)

 (ii) if the proposed transferor is an Agent Member holding a beneficial interest in the Global Note, upon receipt by the Registrar of (x)
the documents, if any, required by clause (i) and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and a decrease in the principal
amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall execute, and the Trustee shall authenticate and deliver, one or more Certificated Notes of

writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who is a QIB within the meaning of Rule 144A and is aware that the sale to it is being made in reliance on Rule 144A; and 
  
 (ii) if the proposed transferee is an Agent Member, and the
Note to be transferred consists of Certificated Notes or an interest in the Regulation S Global Note, upon receipt by the Registrar of the documents referred to in clause (i) and instructions given in accordance with the Depositary’s and the
Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the Certificated Notes or the interest in
the Regulation S Global Note, as the case may be, to be transferred, and the Trustee shall cancel the Certificated Notes or decrease the amount of the Regulation S Global Note so transferred. 
  
 (e) Transfers of Interests in the Temporary Regulation S Global Note.
The following provisions shall apply with respect to the registration of any proposed transfer of interests in the Temporary Regulation S Global Note: 
  
 (i) the Registrar shall register the transfer of an interest in the Temporary Regulation S Global Note if (x) the proposed transferor has
delivered to the Registrar a certificate substantially in the form of Exhibit F stating, among other things, that the proposed transferee is a Foreign Person or (y) the proposed transferee is a QIB and the proposed transferor has checked the
box provided for on a certificate substantially in the form of Exhibit D(2) stating, or has otherwise advised the Issuer and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee
who is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A; and 
  
 (ii) if the proposed transferee is an Agent Member, upon receipt by the Registrar of the documents referred to in clause (i)(y) above and
instructions given in accordance with the Depositary’s and the Registrar’s procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Rule 144A Global Note in an amount equal to
the principal amount of the Temporary Regulation S Global Note to be transferred, and the Trustee, as Note Custodian, shall decrease the amount of the Temporary Regulation S Global Note. 
  
 (f) Transfers to Foreign Persons. The following provisions shall apply with respect to any transfer of a Transfer

 (ii) (a) if the proposed transferor is an Agent Member holding a beneficial interest in
the Rule 144A Global Note or the Note to be transferred consists of Certificated Notes, upon receipt by the Registrar of (x) the documents, if any, required by paragraph (i) and (y) instructions in accordance with the Depositary’s and the
Registrar’s procedures, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in the Rule 144A
Global Note or cancel the Certificated Notes, as the case may be, to be transferred, and (b) if the proposed transferee is an Agent Member, upon receipt by the Registrar of instructions given in accordance with the Depositary’s and the

Initially, the Rule 144A Global Note and the Regulation S Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Note Custodian for Cede & Co. 

 
 Certificated Notes issued in exchange for all or a part of a Global Note
pursuant to this Section 2.6 shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and
authentication, the Trustee shall deliver such Certificated Notes to the Persons in whose names such Certificated Notes are so registered. 
  
 Certificated Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the Rule 144A Global Note or the Permanent
Regulation S Global Note, as the case may be, if at any time the Depositary for the Notes notifies the Issuer that the Depositary is unwilling or unable to continue as Depositary for the Rule 144A Global Note or the Permanent Regulation S Global
Note, as the case may be, and a successor Depositary is not appointed by the Issuer within 90 days after delivery of such notice; the Issuer shall execute, and the Trustee shall, upon receipt of an authentication order in accordance with Section 2.2
hereof, authenticate and deliver such Certificated Notes in an aggregate principal amount equal to the principal amount of the Rule 144A Global Note or the Permanent Regulation S Global Note, as the case may be, in exchange for such Global Notes.

  
 (h) Legends. 
  
 (i) Except as permitted by the following paragraphs (ii) and
(iii), each Note certificate evidencing Global Notes and Certificated Notes (and all Notes issued in exchange therefor or substitution thereof) shall (x) be subject to the restrictions on transfer set forth in this Section 2.6 (including those set
forth in the legend below) unless such restrictions on transfer shall be waived by written consent of the Issuer, and the Holder of each Transfer Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such
restrictions on transfer, and (y) bear the legend set forth below (the “Private Placement Legend”): 
  
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS
AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED
INSTITUTIONAL 
  

 -33- 








 BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS NOT A U.S. PERSON AND IS
ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT OR (C) IT IS AN ACCREDITED INVESTOR (AS DEFINED IN RULE 501(a)(1), (2), (3), OR (7) UNDER THE SECURITIES ACT (AN “ACCREDITED
INVESTOR”), (2) AGREES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS BEHALF BY A U.S. BROKER-DEALER) TO THE TRUSTEE A
SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE FOR THIS SECURITY), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE
TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER SO REQUESTS), OR (G) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM
THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, IF THE PROPOSED TRANSFEREE IS AN ACCREDITED INVESTOR,
THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY
REGULATION S UNDER THE SECURITIES ACT. 
  
 (ii)
Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Note) pursuant to Rule 144 under the Securities Act or pursuant to an effective registration statement under the
Securities Act: 
  
 (a) in the case of any
Transfer Restricted Security that is a Certificated Note, the Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a Certificated Note that does not bear the legend set forth in (i) above and rescind any
restriction on the transfer of such Transfer Restricted Security; and 
  
 (b) in the case of any Transfer Restricted Security represented by a Global Note, such Transfer Restricted Security shall not be required to bear the legend set forth in (i) above, but shall continue to be subject to
the provisions of Section 2.6(b) hereof; 
  

 -34- 








 provided, however, that with respect to any request for an exchange of a Transfer
Restricted Security that is represented by a Global Note for a Certificated Note that does not bear the legend set forth in (i) above, which request is made in reliance upon Rule 144, the Holder thereof shall certify in writing to the Registrar that
such request is being made pursuant to Rule 144 (such certifications to be substantially in the form of Exhibit D(2) hereto). 
  
 (iii) Notwithstanding the foregoing, upon consummation of the Exchange Offer, the Issuer shall issue and, upon receipt of an
authentication order in accordance with Section 2.2 hereof, the Trustee shall authenticate Series B Notes in exchange for Series A Notes accepted for exchange in the Exchange Offer, which Series B Notes shall not bear the legend set forth in (i)
above, and the Registrar shall rescind any restriction on the transfer of such Series A Notes, in each case unless the Issuer has notified the Registrar in writing that the Holder of such Series A Notes is either (A) a broker-dealer, (B) a Person
participating in the distribution of the Series A Notes or (C) a Person who is an affiliate (as defined in Rule 144A) of the Issuer. 
  
 (iv) Each Global Note, whether or not a Transfer Restricted Security, shall also bear the following legend on the face thereof:

  
 THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE
INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE OF A DEPOSITARY OR A SUCCESSOR DEPOSITARY. THIS NOTE IS NOT EXCHANGEABLE FOR NOTES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS
NOMINEE EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER OF THIS SECURITY AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE
DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. 
  
 UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE
ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO
CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO.,
HAS AN INTEREST HEREIN. 
  
 (v) Any Global Note
may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Note Custodian, the Depositary or by the National Association of
Securities Dealers, Inc. in order for the Notes to be tradable on the PORTAL Market or as may be required 
  

 -35- 








 for the Notes to be tradable on any other market developed for trading of securities pursuant to Rule
144A or Regulation S under the Securities Act or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or
traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Notes are subject. 
  
 (i) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in Global Notes have been exchanged for Certificated
Notes, redeemed, repurchased or canceled, all Global Notes shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for Certificated Notes, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Notes shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or the Note
Custodian, at the direction of the Trustee, to reflect such reduction. In the event of any transfer of any beneficial interest between the Rule 144A Global Note and the Regulation S Global Note in accordance with the standing procedures and
instructions between the Depositary and the Note Custodian and the transfer restrictions set forth herein, the aggregate principal amount of each of the Rule 144A Global Note and the Regulation S Global Note shall be appropriately increased or
decreased, as the case may be, and an endorsement shall be made on each of the Rule 144A Global Note and the Regulation S Global Note by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction or increase.

  
 (j) General Provisions Relating to Transfers and Exchanges.

  
 (i) To permit registrations of transfers and
exchanges, the Issuer shall execute and the Trustee shall authenticate Certificated Notes and Global Notes at the Registrar’s request. 
  
 (ii) No service charge shall be made to a Holder for any registration of transfer, fee or exchange, but the Issuer may require payment of
a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.6 and 9.5 hereof).

  
 (iii) The Registrar shall not be required to
register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
  
 (iv) All Certificated Notes and Global Notes issued upon any registration of transfer or exchange of Certificated Notes or Global Notes
shall be the valid obligation of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Certificated Notes or Global Notes surrendered upon such registration of transfer or exchange. 
  
 (v) The Issuer shall not be required: 
  
 (a) to issue, to register the transfer of or to exchange
Notes during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of such mailing; or 
  

 -36- 








 (b) to register the transfer of or to exchange any Note so selected for redemption in
whole or in part, except the unredeemed portion of any Note being redeemed in part; or 
  
 (c) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 
  
 (vi) Prior to due presentment of the registration of a
transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of all payments with respect to such Notes, and neither the Trustee,
any Agent nor the Issuer shall be affected by notice to the contrary. 
  
 (vii) Each Holder of a Note agrees to indemnify the Issuer and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of
this Indenture and/or applicable United States federal or state securities law. 
  
 (viii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Notes) other than to
require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to
form with the express requirements hereto. 
  
 (ix) Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary. 
  
 (x) The Trustee shall authenticate Certificated Notes and Global Notes in accordance with the provisions of Section 2.2 hereof.

  
 SECTION 2.7. Replacement Notes.

  
 If any mutilated Note is surrendered to the Trustee or the
Issuer or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of an authentication order in accordance with Section 2.2 hereof, shall authenticate a
replacement Note if the Trustee’s requirements for replacement of Notes are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and
any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Trustee and the Issuer each may charge such Holder for their expenses in replacing such Note. 
  
 Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this
Indenture equally and proportionately with all other Notes duly issued hereunder. 
  
 SECTION 2.8. Outstanding Notes. 
  
 The Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those paid pursuant to Section 2.6 
  

 -37- 








 hereof, those reductions in the interest in a Global Note effected by the Trustee or the Note Custodian in accordance
with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note. 
  
 If a Note is replaced pursuant to Section 2.7 hereof, it shall cease to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser for value. 
  
 If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

  
 If the Paying Agent (other than the Issuer, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

  
 SECTION 2.9. Treasury Notes.

  
 In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, the Guarantors or by any Affiliate thereof shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee
shall be protected in conclusively relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. The Issuer agrees to notify the Trustee of the existence
of any such treasury Notes or Notes owned by the Issuer, any Guarantor or, to the knowledge of the Issuer, an Affiliate thereof. 
  
 SECTION 2.10. Temporary Notes. 
  
 Until Certificated Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an authentication order in accordance with
Section 2.2 hereof, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Certificated Notes, but may have such variations as the Issuer considers appropriate for temporary Notes and as shall be reasonably
acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Certificated Notes in exchange for temporary Notes. 
  
 Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. 
  
 SECTION 2.11. Cancellation. 
  
 The Issuer at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or Paying Agent, and no one else shall cancel
all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of all canceled Notes in accordance with the Trustee’s usual procedures. The Trustee shall maintain a record of all canceled
Notes. All canceled Notes shall be delivered to the Issuer if the Issuer so requests in writing. Subject to Section 2.7 hereof, the Issuer may not issue new Notes to replace Notes that have been paid or that have been delivered to the Trustee for
cancellation. 
  

 -38- 








 SECTION 2.12. Defaulted Interest. 
  
 If the Issuer defaults in a payment of interest on the Notes, the Issuer
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 Notes
and in Section 4.1 hereof. The Issuer shall promptly notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer 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 Issuer (or, upon the
written request of the Issuer, the Trustee in the name and at the expense of the Issuer) 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.

  
 SECTION 2.13. Persons Deemed Owners.

  
 Prior to due presentment of a Note for registration of
transfer and subject to Section 2.12 hereof, the Issuer, the Trustee, any Paying Agent, any co-registrar and any Registrar may deem and treat the person in whose name any Note shall be registered upon the register of Notes kept by the Registrar as
the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of the ownership or other writing thereon made by anyone other than the Issuer, any co-registrar or any Registrar) for the purpose of
receiving all payments with respect to such Note and for all other purposes, and none of the Issuer, the Trustee, any Paying Agent, any co-registrar or any Registrar shall be affected by any notice to the contrary. 
  
 SECTION 2.14. CUSIP Numbers. 
  
 The Issuer in issuing the Notes may use a “CUSIP” number, and if
so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed
in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee in writing of any change to the CUSIP numbers. 
  
 ARTICLE III 
  
 REDEMPTION AND REPURCHASE 
  
 SECTION 3.1. Notices to Trustee. 
  
 If the Issuer elects to redeem Notes pursuant to the provisions of Section 3.7 or 3.8 hereof, it shall furnish to the Trustee, at least 30 days but not
more than 60 days before the Redemption Date (unless a shorter notice period shall be satisfactory to the Trustee), an Officers’ Certificate setting forth the Section of this Indenture pursuant to which the redemption shall occur, the
Redemption Date, the principal amount of Notes to be redeemed and the Redemption Price. 
  
 If the Issuer is required to offer to repurchase Notes pursuant to the provisions of Section 4.10, 4.15 or 4.19 hereof, it shall notify the Trustee in writing, (i) in the case of a repurchase pursuant to Section 4.10
or 4.19, at least 30 days but not more than 45 days, or (ii) in the case of a repurchase pursuant to Section 4.15, at least 30 days but not more than 60 days before the Purchase Date, of the Section 
  

 -39- 








 of this Indenture pursuant to which the repurchase shall occur, the Purchase Date, the principal amount of Notes required
to be repurchased and the Purchase Price and shall furnish to the Trustee an Officers’ Certificate to the effect that (a) the Issuer is required to make or has made a Net Proceeds Offer or a Change of Control Offer or a Loss Proceeds Offer, as
the case may be, and (b) the conditions set forth in Section 4.10, 4.15 or 4.19 hereof, as the case may be, have been satisfied. 
  
 If the Registrar is not the Trustee, the Issuer shall, concurrently with each notice of redemption or repurchase, cause the Registrar to deliver to the
Trustee a certificate (upon which the Trustee may rely) setting forth the principal amounts of Notes held by each Holder. 
  
 SECTION 3.2. Selection of Notes. 
  
 Except as set forth below, if less than all of the Notes are to be redeemed, the Trustee shall select the Notes or portions thereof to be redeemed in
compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate. In the event of partial
redemption by lot, the particular Notes or portions thereof 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 Notes not
previously called for redemption. 
  
 If less than all of the
Notes tendered are to be repurchased pursuant to the provisions of Section 4.10 or 4.19 hereof, the Trustee shall select the Notes or portions thereof to be repurchased in compliance with Section 4.10 or 4.19 hereof. In the event of partial
repurchase by lot, the particular Notes or portions thereof to be repurchased shall be selected at the close of business of the last Business Day prior to the Purchase Date. If less than all of the Notes tendered are to be repurchased pursuant to
the provisions of Section 3.8 hereof, the Trustee shall select the Notes only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to DTC procedures). 
  
 The Trustee shall promptly notify the Issuer in writing of the Notes or
portions thereof selected for redemption or repurchase. Notes and portions thereof selected shall be in amounts of $1,000 or integral multiples of $1,000, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount
of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. No Notes of a principal amount of $1,000 or less shall be redeemed in part. 
  

SECTION 3.3. Notice of Optional or Special Redemption. 
  
 In the event Notes are to be redeemed pursuant to Section 3.7 or 3.8 hereof, at least 30 days but not more than 60 days
before the Redemption Date, the Issuer shall mail a notice of redemption to each Holder whose Notes are to be redeemed in whole or in part, with a copy to the Trustee. 
  
 The notice shall identify the Notes or portions thereof to be redeemed (including the CUSIP number, if any) and shall state:

  
 (a) the Redemption Date; 
  
 (b) the Redemption Price; 
  
 (c) if any Note is being redeemed in part, the portion of
the principal amount of such Note to be redeemed and that, after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued; 
  

 -40- 








 (d) the name and address of the Paying Agent; 
  
 (e) that Notes called for redemption must be surrendered to
the Paying Agent to collect the Redemption Price, Additional Interest, if any, and, unless the Redemption Date is after a record date and or before the succeeding interest payment date, accrued interest thereon to the Redemption Date; 
  
 (f) that, unless the Issuer defaults in making the
redemption payment, interest and any Additional Interest on Notes called for redemption will cease to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price,
any Additional Interest and, unless the Redemption Date is after a record date and on or before the succeeding interest payment date, accrued interest thereon to the Redemption Date upon surrender to the Paying Agent of the Notes redeemed;

  
 (g) if fewer than all the Notes are to be
redeemed, the identification of the particular Notes (or portions thereof) to be redeemed, as well as the aggregate principal amount of the Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial
redemption; 
  
 (h) the paragraph of the Notes
pursuant to which the Notes called for redemption are being redeemed; and 
  
 (i) 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 Notes and that reliance may be placed only on the other identification numbers
printed on the Notes. 
  
 At the Issuer’s request, the
Trustee shall give the notice of redemption in the Issuer’s name and at its expense; provided that the Issuer shall deliver to the Trustee, at least 35 days prior to the Redemption Date (unless a shorter period shall be satisfactory to
the Trustee), 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 3.4. Effect of Notice of Redemption.

  
 Once notice of redemption is mailed, Notes or portions
thereof called for redemption become due and payable on the Redemption Date at the Redemption Price. Upon surrender to any Paying Agent, such Notes or portions thereof shall be paid at the Redemption Price, plus Additional Interest, if any,
and accrued interest to the Redemption Date; provided, however, that installments of interest which are due and payable on or prior to the Redemption Date shall be payable to the Holders of such Notes, registered as such, at the close
of business on the relevant record date for the payment of such installment of interest. 
  
 SECTION 3.5. Deposit of Redemption Price. 
  
 On or before 10:00 a.m. Eastern Time on each Redemption Date, the Issuer shall irrevocably deposit with the Trustee or with
the Paying Agent money sufficient to pay the aggregate amount due on all Notes to be redeemed on that date, including without limitation any accrued and unpaid interest and Additional Interest, if any, to the Redemption Date. Upon written request by
the Issuer, the Trustee or the Paying Agent shall promptly return to the Issuer any money not required for that purpose. 
  

 -41- 








 Unless the Issuer defaults in making such payment, interest and any Additional Interest on the Notes to
be redeemed will cease to accrue on the applicable Redemption Date, whether or not such Notes are presented for payment. If any Note called for redemption shall not be so paid upon surrender because of the failure of the Issuer to comply with the
preceding paragraph, interest will be paid on the unpaid principal, from the applicable Redemption Date until such principal is paid, and on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in
Section 4.1 hereof. 
  
 SECTION 3.6. Notes
Redeemed in Part. 
  
 Upon surrender of a Note that is
redeemed in part, the Issuer shall issue and the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to portion of the Note surrendered that is not to be redeemed. 
  
 SECTION 3.7. Optional Redemption. 
  
 The Issuer may redeem any or all of the Notes at any time on or after
October 1, 2006 at the Redemption Prices set forth in the Notes (an “Optional Redemption”). Any redemption pursuant to this Section 3.7 shall be made pursuant to the provisions of Sections 3.1 through 3.6 hereof.

the Issuer has violated any provisions of Article IV or Article V hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such violation. 
  
 The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith (and in any event within five Business Days) upon the Issuer becoming aware of any Default or Event of Default an
Officers’ Certificate specifying such Default or Event of Default.

 (b) this Indenture, the Notes, the Guarantees and the Collateral Documents; 
  
 (c) a Credit Facility and the security agreements and other collateral documents relating thereto; 
  

 -50- 








 (d) any agreement or instrument governing Acquired Indebtedness, which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; 
  
 (e) agreements existing on the Issue Date to the extent and in the manner such encumbrances or restrictions

applicable Restricted Subsidiary in any material respect as determined by the Board of Directors of the Issuer in its reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in agreements referred
to in such clauses (b), (d), (e) and (f). 
  
 Nothing contained in
this Section 4.8 shall prevent the Issuer or any of its Restricted Subsidiaries from creating, incurring, assuming or suffering to exist any Liens otherwise permitted in Section 4.12 hereof. 
  
 SECTION 4.9. Limitation on Incurrence of Additional
Indebtedness. 
  
 (a) The Issuer will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively,
“incur”) any Indebtedness (other than Permitted Indebtedness); provided, however, that, if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of
any such Indebtedness, the Issuer or any of its Restricted Subsidiaries that is or, upon such incurrence, becomes a Guarantor may incur Indebtedness (including, without limitation, Acquired Indebtedness) and any Restricted Subsidiary of the Issuer
that is not or will not, upon such incurrence, become a Guarantor may incur Acquired Indebtedness, in each case if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Indebtedness to Cash Flow Ratio
of the Issuer would not have exceeded 4.5 to 1.0. 
  

 -51- 








 (b) The Issuer will not, and will not permit any Guarantor to, directly or indirectly, incur any
Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is expressly subordinated in right of payment to any other Indebtedness of the Issuer or such Guarantor, as the case may be, unless such Indebtedness is
also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the applicable Guarantee, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated
to such other Indebtedness of the Issuer or such Guarantor, as the case may be. For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Issuer or any Guarantor solely by
virtue of such Indebtedness being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into one or more intercreditor agreements giving one or more of such holders priority over the other holders in the collateral
held by them. 
  
 (c) In addition to the limitation imposed by
Section 4.09(a) hereof, any issuance of Additional Notes shall be subject to the further requirements set forth in Section 4.12 hereof and that the Issuer shall, at its sole cost and expense, have performed or caused to be performed all acts and
executed any and all documents (including, without limitation, the authorization of any financing statement and continuation statement) for filing under the provisions of the Uniform Commercial Code or under any other statute, rule or regulation of
any applicable federal, state or local jurisdiction, including any filings in local real estate land record offices that are necessary or reasonably requested by the Trustee in order to grant and confirm the validity, perfection and second priority
(subject to Permitted Liens) of the Liens in favor of the Trustee for the benefit of the Holders on such additional Collateral. 
  
 (d) Notwithstanding the foregoing or any other provision of this Indenture, the Issuer will not, and will not permit any of its Subsidiaries to, directly
or indirectly, incur any Indebtedness, the proceeds of which will be used, directly or indirectly, to redeem, repurchase or otherwise retire the Convertible Preferred Stock (or any replacement, refunding or renewal thereof) on or prior to October 1,
2009. 
  
 SECTION 4.10. Limitation on Asset
Sales. 
  
 (a) The Issuer will not, and will not permit any
of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
  
 (1) the Issuer or the applicable Restricted 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 sold or otherwise disposed of (as
determined in good faith by the Issuer’s Board of Directors); 
  
 (2) at least 75% of the consideration received by the Issuer or the Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash or Cash Equivalents and is received at the time of such
disposition (provided that (A) the amount of any liabilities of the Issuer or any such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or any Guarantee thereof) that are assumed by the transferee of
any such assets and (B) any securities or other obligations received by the Issuer or any such Restricted Subsidiary in exchange for any such assets (other than assets which constitute Collateral) that are converted into cash within 180 days after
the consummation of such Asset Sale (to the extent of the cash received) shall be deemed to be cash for purposes of this provision); 
  
 (3) if such Asset Sale involves the disposition of Collateral, subject to the Intercreditor Agreement, the Issuer or such Restricted
Subsidiary has complied with the provisions described in Article X hereof; 
  

 -52- 








 (4) if such Asset Sale involves the disposition of Collateral, subject to the
Intercreditor Agreement, the Net Cash Proceeds relating to such Asset Sale remaining after repayment (including a corresponding commitment reduction, if applicable) of any Indebtedness secured by a Permitted Lien on such asset (the
“Available Amount”) shall be paid directly by the purchaser of the Collateral to the Trustee for deposit into the Collateral Account for the benefit of the Trustee, and, to the extent required by the Collateral Documents, such
property shall be made subject to the Lien of the applicable Collateral Documents; and 
  
 (5) upon the consummation of an Asset Sale, the Issuer shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds
relating to such Asset Sale within 365 days of receipt thereof either: 
  
 (a) to prepay any Secured Indebtedness; 
  
 (b) to make an investment in properties and assets that replace the properties and assets that were the subject of such Asset Sale or in properties and assets (including Capital Stock) that will be used in the
business as existing on the Issue Date of the Issuer and its Restricted Subsidiaries or in businesses reasonably related thereto (“Replacement Assets”) or to make a Permitted Investment; provided that any Replacement Assets
acquired with any Net Cash Proceeds of an Asset Sale of Collateral shall be owned by the Issuer or a Guarantor and shall not be subject to any Liens other than Permitted Liens and the Issuer or such Guarantor, as the case may be, shall execute and
deliver to the Trustee such Collateral Documents or other instruments as shall be reasonably necessary to cause such property or assets to become subject to the Lien of the applicable Collateral Documents; and/or 
  
 (c) a combination of prepayment and investment permitted by
the foregoing clauses (5)(a) and (5)(b). 
  
 Clauses (1) and (2)
of Section 4.10(a) hereof need not be satisfied to the extent the Collateral to be released consists solely of Collateral with respect to which the required Lenders have given their consent and authorized the release of same or to the extent the
Collateral to be released is disposed of by the agent on behalf of the required Lenders in connection with the exercise of rights or remedies under a Credit Facility, in each case so long as the proceeds therefrom are applied in accordance with the
Intercreditor Agreement. 
  
 (b) On the 366th day after an Asset
Sale (a “Net Proceeds Offer Trigger Date”), such aggregate amount of Net Cash Proceeds which have not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (5)(a), (5)(b) and (5)(c) of Section
4.10(a) hereof (each, a “Net Proceeds Offer Amount”) shall be applied by the Issuer or such Restricted Subsidiary to make an offer to purchase (the “Net Proceeds Offer”) on a date (the “Net Proceeds Offer
Payment Date”) not less than 30 nor more than 45 days following the applicable Net Proceeds Offer Trigger Date, from all Holders on a pro rata basis, that amount of Notes equal to the Net Proceeds Offer Amount at a price equal to
100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the date of purchase; provided, however, that if at any time any non-cash consideration received by the Issuer or any
Restricted Subsidiary of the Issuer, as the case may be, in connection with any Asset Sale which does not involve Collateral is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash
consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.10. Pending application of the Net Cash Proceeds, the Net
Cash Proceeds from Asset Sales of Collateral shall be deposited in the Collateral Account. To the extent that the aggregate 
  

 -53- 








 amount of Notes tendered pursuant to a Net Proceeds Offer is less than the Net Proceeds Offer Amount, the Issuer may
apply any remaining Net Cash Proceeds to any purpose consistent with this Indenture and, following the consummation of each Net Proceeds Offer, the Net Proceeds Offer Amount shall be reset to zero. Notwithstanding anything to the contrary in the
foregoing, the Issuer may commence a Net Proceeds Offer prior to the expiration of 360 days after the occurrence of an Asset Sale. 
  
 (c) The Issuer may defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount that, when added to the Net Loss Proceeds
then accumulated, is equal to or in excess of $5.0 million (the “Total Offer Amount”) (at which time, the entire unutilized Total Offer Amount, and not just the amount in excess of $5.0 million, shall be applied as required pursuant
to the preceding paragraph). 
  
 (d) Notwithstanding Sections
4.10(a) and 4.10(b) hereof, the Issuer and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such Sections 4.10(a) and 4.10(b) hereof to the extent that: 
  
 (1) the consideration for such Asset Sale constitutes Replacement Assets;
and 
  
 (2) such Asset Sale is for fair market value; 

 
 provided that to the extent such Asset Sale consists of Collateral, the Replacement
Assets shall be owned by the Issuer or a Guarantor and shall not be subject to any Liens other than Permitted Liens and the Issuer or such Guarantor shall execute and deliver to the Trustee such Collateral Documents or other instruments as shall be
reasonably necessary to cause such property or assets to become subject to the Lien of the applicable Collateral Documents. 
  
 (e) In the event of the transfer of substantially all (but not all) of the property and assets of the Issuer and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 5.1 hereof, which transaction does not constitute a Change of Control, the successor corporation shall be deemed to have sold the properties and assets of the Issuer and its Restricted
Subsidiaries not so transferred for purposes of this Section 4.10, and shall comply with the provisions of this Section 4.10 with respect to such deemed sale as if it were an Asset Sale. In addition, the fair market value of such properties and
assets of the Issuer or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section 4.10. 
  
 (f) The Issuer 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 are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the “Asset Sale” provisions
of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the “Asset Sale” provisions of this Indenture by virtue thereof. 
  
 SECTION 4.11. Limitations on Transactions with
Affiliates. 
  
 (a) The Issuer will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of
any service) with, or for the benefit of, any of its Affiliates (each, an “Affiliate Transaction”), other than (x) Affiliate Transactions permitted under Section 4.11(c) hereof and (y) Affiliate Transactions on terms that are no
less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Issuer or such Restricted Subsidiary. 
  

 -54- 








 (b) All Affiliate Transactions (and each series of related Affiliate Transactions that are similar or
part of a common plan) involving aggregate payments or other property with a fair market value in excess of $2.5 million shall, prior to the consummation thereof, be approved by a majority of the disinterested members of the Board of Directors of
the Issuer or such Restricted Subsidiary, as the case may be, such approval to be evidenced by a Board Resolution stating that such disinterested members (or the disinterested member, if there is only one disinterested member) have determined that
such transaction complies with the foregoing provisions. If the Issuer or any Restricted Subsidiary of the Issuer enters into an Affiliate Transaction (or a series of related Affiliate Transactions that are similar or part of a common plan)
involving aggregate payments or other property with a fair market value in excess of $10.0 million, the Issuer or such Restricted Subsidiary, as the case may be, shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness
of such transaction or series of related transactions to the Issuer or the relevant Restricted Subsidiary, as the case may be, from a financial point of view, from an Independent Financial Advisor and file the same with the Trustee. 
  
 (c) The restrictions set forth Sections 4.11(a) and 4.11(b) hereof shall not
apply to: 
  
 (1) reasonable fees and
compensation paid to and indemnity provided on behalf of officers, directors, employees or consultants of the Issuer or any Restricted Subsidiary of the Issuer as determined in good faith by the Issuer’s Board of Directors or senior management;

  
 (2) transactions exclusively between or among
the Issuer and any of its Wholly Owned Restricted Subsidiaries or exclusively between or among such Wholly Owned Restricted Subsidiaries, provided, that such transactions are not otherwise prohibited by this Indenture; 
  
 (3) any agreement as in effect as of the Issue Date or any
amendment thereto or any transaction contemplated thereby (including pursuant to any amendment thereto) or any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders in any
material respect than the original agreement as in effect on the Issue Date; and 
  
 (4) Restricted Payments permitted by this Indenture. 
  
 SECTION 4.12. Limitation on Liens. 
  
 The Issuer will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or permit or suffer to exist any Liens of any kind against or upon any property or assets of the Issuer or any of its Restricted Subsidiaries, whether owned on the Issue Date or acquired after the Issue Date, or any proceeds therefrom,
or assign or otherwise convey any right to receive income or profits therefrom, in each case other than Permitted Liens, except that the Issuer and its Restricted Subsidiaries may incur Liens on property or assets that are not Collateral if (i) in
the case of any such Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes, the Notes are secured by a Lien on such property or assets that is senior in priority to such Liens and (ii) in the case of
all other such Liens, the Notes are equally and ratably secured. In the event that the Lien the existence of which gives rise to a Lien securing the Notes or a Guarantee pursuant to the foregoing exception ceases to exist, the Lien securing the
Notes or a Guarantee required by the foregoing exception shall automatically be released and the Trustee shall execute appropriate documentation as requested by the Issuer. 
  

 -55- 








 SECTION 4.13. Continued Existence. 
  
 Subject to Article V hereof, the Issuer shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its corporate or other existence and the corporate or other existence of each Guarantor in accordance with the organizational documents (as the same may be amended from time to time)
of the Issuer or such Guarantor and (ii) the material rights (charter and statutory), licenses and franchises of the Issuer or such Guarantor, except to the extent that the applicable Board of Directors determines in good faith that the preservation
of such right, license or franchise is no longer necessary or desirable in the conduct of the business of the Issuer and the Guarantors, taken as a whole. 
  
 SECTION 4.14. Insurance Matters. 
  
 (a) The Issuer shall provide or cause to be provided, for itself and each of its Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds that, in the reasonable, good faith opinion of the Issuer, are adequate and appropriate for the conduct of the business of the Issuer and its Restricted Subsidiaries in a prudent manner, with reputable insurers or
with the government of the United States of America or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Issuer, for corporations
similarly situated in the industry, unless the failure to provide such insurance (together with all other such failures) would not have a material adverse effect on the financial condition or results of operations of the Issuer and its Restricted
Subsidiaries, taken as a whole. 
  
 (b) The Issuer shall use its
commercially reasonable efforts, and shall cause each of its Restricted Subsidiaries to use its commercially reasonable efforts, subject to and in compliance with the provisions of Article X and the applicable Collateral Documents, to include in any
insurance policy maintained by the Company with respect to any Collateral that all losses payable thereunder shall be payable to the Trustee, as either loss payee or additional insured, as applicable. 
  
 SECTION 4.15. Offer to Repurchase upon Change of
Control. 
  
 Upon the occurrence of a Change of Control, each
Holder of Notes shall have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Notes (a “Change of Control Offer”) at a Purchase Price in cash equal
to 101% of the aggregate principal amount thereof, together with accrued and unpaid interest and Additional Interest, if any, thereon to the Purchase Date. The Change of Control Offer shall be made in compliance with the applicable procedures set
forth in Article III hereof and shall include all instructions and materials necessary to enable Holders to tender their Notes. 
  
 The Issuer will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control
Offer. 
  
 The Issuer 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 are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section
4.15 by virtue thereof. 
  

 -56- 








 SECTION 4.16. Guarantees of Restricted Subsidiaries. 
  
 Each Restricted Subsidiary of the Issuer (other than a Foreign Restricted
Subsidiary) shall execute and deliver to the Trustee a supplemental indenture pursuant to which such Restricted Subsidiary shall unconditionally guarantee on a senior basis all obligations of the Issuer under the Notes, and shall agree to be bound
by this Indenture and the Collateral Documents and, subject to the Intercreditor Agreement, pledge its assets as collateral for its Guarantee in accordance therewith. 
  
 SECTION 4.17. Conduct of Business. 
  
 The Issuer and its Restricted Subsidiaries will not engage in any businesses that are not the same, similar, ancillary or
reasonably related to the businesses in which the Issuer and its Restricted Subsidiaries are engaged on the Issue Date. 
  
 SECTION 4.18. Payments for Consent. 
  
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or
for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the
Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
  
 SECTION 4.19. Events of Loss. 
  
 (a) In the event of an Event of Loss with respect to any Collateral, the Issuer or the affected Subsidiary Guarantor, as the case may be, will apply the
Net Loss Proceeds from such Event of Loss, within 365 days after receipt, at its option: 
  
 (1) to the rebuilding, repair, replacement or construction of improvements to the affected property (the “Subject
Property”); 
  
 (2) to make capital
expenditures with respect to Collateral or to acquire properties or assets that will (a) constitute Collateral and (b) be used or useful in the Permitted Business of the Issuer or any of its Restricted Subsidiaries; provided that any
Collateral acquired with any Net Loss Proceeds shall be owned by the Issuer or a Guarantor and shall not be subject to any Liens other than Permitted Liens and the Issuer or such Guarantor, as the case may be, shall execute and deliver to the
Trustee such Collateral Documents or other instruments as shall be reasonably necessary to cause such property or assets to become subject to the Lien of the applicable Collateral Documents; and/or 
  
 (3) a combination of the uses permitted by the foregoing
clauses (1) and (2) above. 
  
 (b) On the 366th day after an Event
of Loss (a “Loss Proceeds Offer Trigger Date”), such aggregate amount of Net Loss Proceeds which have not been applied on or before such Loss Proceeds Offer Trigger Date as permitted in clauses (a)(1), (a)(2) and (a)(3) above (each
a “Loss Proceeds Offer Amount”) shall be applied by the Issuer or such Subsidiary Guarantor to make an offer to purchase (the “Loss Proceeds Offer”) on a date (the “Loss Proceeds Offer Payment
Date”) not less than 30 nor more than 45 days following the applicable Loss Proceeds Offer Trigger Date, from all Holders on a pro rata basis, that amount of Notes equal to the Loss Proceeds Offer Amount at a price equal to 100% of
the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to the 
  

 -57- 








 date of purchase. Pending application of the Net Loss Proceeds, the Net Loss Proceeds shall be deposited in the
Collateral Account. To the extent that the aggregate amount of Notes tendered pursuant to a Loss Proceeds Offer is less than the Loss Proceeds Offer Amount, the Issuer may apply any remaining Net Loss Proceeds to any purpose consistent with this
Indenture and, following the consummation of each Loss Proceeds Offer, the Loss Proceeds Offer Amount shall be reset to zero. Notwithstanding anything to the contrary in the foregoing, the Issuer may commence a Loss Proceeds Offer prior to the
expiration of 365 days after the occurrence of an Event of Loss. 
  
 (c) The Issuer may defer any Loss Proceeds Offer until there is an aggregate unutilized Total Offer Amount equal to or in excess of $5.0 million (at which time, the entire unutilized Total Offer Amount, and not just the amount in excess of
$5.0 million, shall be applied as required pursuant to the preceding paragraph). 
  
 (d) The Issuer 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 or regulations are applicable in connection with
the repurchase of the Notes pursuant to a Loss Proceeds Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with the provisions of this Indenture, the Issuer will comply with such securities laws and
regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

 In the event that the Issuer is required to pay Additional Interest (as defined in the applicable Registration Rights
Agreement) to Holders of Notes pursuant to the Registration Rights Agreement, the Issuer will provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than 5 days
prior to the proposed payment date for the Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Issuer on such payment date. The Trustee shall not at any time be under any duty
or responsibility to any Holder of Notes to determine the Additional Interest, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the
Additional Interest. 
  
 SECTION 4.21.
Limitation on Preferred Stock of Restricted Subsidiaries. 
  
 The Issuer will not permit any of its Restricted Subsidiaries to issue any Preferred Stock (other than to the Issuer or to a Wholly Owned Restricted Subsidiary of the Issuer) or permit any Person (other than the Issuer or a Wholly Owned

 (a) The Issuer will
not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary of the Issuer to sell,
assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Issuer’s assets (determined on a consolidated basis for the 
  

 -58- 








 Issuer and the Issuer’s Restricted Subsidiaries) whether as an entirety or substantially as an entirety to any
Person unless: 
  
 (1) either: 
  
 (a) the Issuer shall be the surviving or continuing
corporation or limited liability company; or 
  
 (b) the Person (if other than the Issuer) formed by such consolidation or into which the Issuer is merged or the Person that acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the
Issuer and its Restricted Subsidiaries substantially as an entirety (the “Surviving Entity”): 
  
 (x) shall be a corporation organized and validly existing under the laws of the United States or any state thereof or the District of
Columbia; and 
  
 (y) shall expressly assume, by
supplemental indenture (in form satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of and premium, if any, and interest on all of the Notes and the performance of every covenant of the
Notes, this Indenture and the Registration Rights Agreement on the part of the Issuer to be performed or observed, and shall cause such amendments, supplements or other instruments to be filed and recorded in such jurisdictions as may be required by
applicable law to preserve and protect the Lien on the Collateral owned by or transferred to the Surviving Entity, together with such financing statements as may be required to perfect any security interests in such Collateral which may be perfected
by the filing of a financing statement under the Uniform Commercial Code of the relevant states; 
  
 (2) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including giving effect
to any Indebtedness and Acquired Indebtedness incurred in connection with or in respect of such transaction), the Issuer or such Surviving Entity, as the case may be, shall be able to incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) in compliance with Section 4.9 hereof; 
  
 (3) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(b)(y) above (including, without limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred
and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing; and 
  
 (4) the Issuer or the Surviving Entity shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each

substantially all of the properties or assets of one or more Restricted Subsidiaries of the Issuer, the Capital Stock of which constitutes all or substantially all of the properties and assets of the Issuer, shall be deemed to be the transfer of all

connection with any transaction complying with the provisions of Section 4.10 hereof) will not, and the Issuer will not cause or permit any Guarantor to, consolidate with or merge with or into any Person other than the Issuer or any other Guarantor

any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any state thereof or the
District of Columbia; 
  
 (2) such entity assumes
by supplemental indenture all of the obligations of the Guarantor on the Guarantee, and shall cause such amendments, supplements or other instruments to be filed and recorded in such jurisdictions as may be required by applicable law to preserve and
protect the Lien on the Collateral owned by or transferred to the Surviving Entity, together with such financing statements as may be required to perfect any security interests in such Collateral which may be perfected by the filing of a financing

 Any merger or consolidation of a Guarantor with and into the Issuer (with the Issuer being the Surviving Entity) or another Guarantor that is a Wholly Owned Restricted Subsidiary of the Issuer need only comply with
Section 5.01(a)(4) hereof. The Collateral owned by such Guarantor or surviving Person, as the case may be, (a) shall be subject to a Lien in favor of the Trustee for the benefit of the Holders; and (b) shall not be subject to any Lien, other than
Permitted Liens. 
  
 SECTION 5.2. Successor
Corporation Substituted.

 ARTICLE VI 
  
 DEFAULTS AND REMEDIES 
  
 SECTION 6.1. Events of Default. 
  
 Each of the following constitutes an “Event of Default”: 
  
 (a) the failure to pay interest on any Notes when the same becomes due and payable and the default continues
for a period of 30 days; 
  
 (b) the failure to
pay the principal of any Notes, when such principal becomes due and payable, at maturity, upon redemption or otherwise (including, without limitation, the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer, a
Net Proceeds Offer or a Loss Proceeds Offer); 
  
 (c) a default in the observance or performance of any other covenant or agreement contained herein or in the Collateral Documents which default continues for a period of 30 days after the Issuer receives written notice specifying the
default (and demanding that such default be remedied and stating that such notice is a “Notice of Default”) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default
with respect to Section 5.1 hereof, which will constitute an Event of Default with such notice requirement but without such passage of time requirement); 
  
 (d) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the stated principal
amount of any Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer (other than a Foreign Restricted Subsidiary that is not a Significant Subsidiary), or the acceleration of the final stated maturity of any such Indebtedness (which
acceleration is not rescinded, annulled or otherwise cured within 20 days of receipt by the Issuer or such Restricted Subsidiary of notice of any such acceleration) if the aggregate principal amount of such Indebtedness, together with the principal
amount of any other such Indebtedness in default for failure to pay principal at final stated maturity or which has been accelerated (in each case with respect to which the 20-day period described above has elapsed), aggregates $5.0 million or more
at any time; 
  
 (e) one or more judgments (not
covered by insurance as to which the carrier has assumed the defense or acknowledged coverage) in an aggregate amount in excess of $5.0 million shall have been rendered against the Issuer or any Restricted Subsidiary of the Issuer (other than a
Foreign Restricted Subsidiary that is not a Significant Subsidiary) and such judgments remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable; 
  
 (f) the Issuer or any Significant Subsidiary of the Issuer:

  
 (i) commences a voluntary case under any
Bankruptcy Law, 
  

 -61-

 SECTION 6.2. Acceleration. 
  
 If an Event of Default (other than an Event of Default specified in Section 6.1(f) or 6.1(g) hereof with respect to the Issuer) shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding
Notes may declare the principal of and accrued and unpaid interest on all the Notes to be due and payable by notice in writing to the Issuer and the Trustee specifying the respective Event of Default and that it is a “notice of
acceleration” (an “Acceleration Notice”), and the same shall become immediately due and payable. 
  

 -62- 








 Notwithstanding the foregoing, if an Event of Default specified in Section 6.1(f) or 6.1(g) hereof occurs
and is continuing with respect to the Issuer, then all unpaid principal of and premium, if any, and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be due and payable without any declaration or act on
the part of the Trustee or any Holder. 
  
 The Holders of not less
than a majority in aggregate principal amount of the then outstanding Notes by written notice to the Issuer and the Trustee may, on behalf of the Holders of all of the Notes, rescind and cancel such declaration and its consequences: 
  
 (1) if the rescission would not conflict with any judgment
or decree; 
  
 (2) if all existing Events of
Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration; 
  
 (3) to the extent the payment of such interest is lawful, if interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid; 
  
 (4) if the Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and 
  
 (5) in the event of the cure or waiver of an Event of Default of the type described in Section 6.1(f) or
6.1(g) hereof, the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. 
  
 No such rescission shall affect any subsequent Default or impair any right consequent thereto. 
  
 SECTION 6.3. 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, interest or Additional Interest, if any, on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Collateral Documents. 
  
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the
proceeding, and any recovery or judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes. A
delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to
the extent permitted by law. 
  
 SECTION 6.4.
Waiver of Past Defaults. 
  
 The Holders of a majority in
principal amount of the Notes may waive any existing Default or Event of Default under this Indenture, and its consequences, except a default in the payment of the principal of or interest on any Notes. 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. 
  

 -63- 








 SECTION 6.5. Control by Majority. 
  
 Holders of a majority in aggregate principal amount of the then outstanding
Notes 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
applicable law or this Indenture that the Trustee reasonably determines may be prejudicial to the rights of other Holders of Notes or that may subject the Trustee to personal liability and shall be entitled to the benefit of Sections 7.1(c)(iii) and
7.1(e) hereof. 
  
 SECTION 6.6. Limitation on
Suits. 
  
 A Holder of a Note may pursue a remedy with
respect to this Indenture or the Notes only if: 
  
 (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 
  
 (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the
remedy; 
  
 (c) such Holder or Holders of Notes
offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; 
  
 (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the
provision of indemnity; and 
  
 (e) during such
60-day period, the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 
  
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note (it
being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to any such Holder). 
  
 SECTION 6.7. Rights of Holders of Notes to Receive Payment. 
  
 Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal of, or premium, if any, interest or Additional Interest, if any, on the Note, on or after the respective due dates thereon (including in connection with an offer to repurchase), 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 written consent of such Holder. 
  
 SECTION 6.8. Collection Suit by Trustee. 
  

If an Event of Default specified in Section 6.l(a) or 6.1(b) hereof occurs and is continuing, the Trustee, after issuance of an Acceleration Notice, is
authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue
principal and, to the extent lawful, interest and Additional Interest, if any, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expense, disbursements and advances
of the Trustee, its agents and counsel. 
  

 -64- 









	SECTION	6.9. 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 (including accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate) and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or
other property payable or deliverable on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7
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 7.7 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 Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 SECTION 6.10. Priorities. 
  
 If the Trustee collects any money pursuant to this Article VI, it shall pay
out the money in the following order, subject to the provisions of the Intercreditor Agreement: 
  
 First: to the Trustee, its agents and attorneys for amounts due under Section 7.7 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 Notes for amounts due and unpaid on the Notes for principal, Purchase Price, Redemption Price and Additional
Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, Purchase Price, Redemption Price and Additional Interest, if any, and interest, respectively;
and 
  
 Third: to the Issuer or to such
party as a court of competent jurisdiction shall direct. 
  
 The Trustee may fix a
special record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
  
 SECTION 6.11. Undertaking for Costs. 
  
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a
Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 TRUSTEE 
  
 SECTION 7.1. 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

financial liability except as expressly provided herein. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, pursuant to the provisions of this Indenture, including,
without limitation, Section 6.5 hereof unless such Holder shall have offered to the Trustee security and indemnity reasonably satisfactory to it against any loss, liability or expense which might be incurred by it in compliance with such request or
direction. 
  
 (g) The Trustee shall not be liable for interest on
any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
  
 SECTION 7.2. Rights of Trustee.

refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

 (g) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder. 
  


 -67- 








 (h) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss
or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

Certificate in the form of Exhibit I setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person
specified as so authorized in any such certificate previously delivered and not superseded. 
  
 SECTION 7.3. Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the
Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest within the meaning of the TIA it must eliminate such conflict within 90 days,
apply (subject to the consent of the Issuer) to the Commission 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 7.4. 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 Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’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 Notes or any other

 SECTION 7.5. Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within
90 days after it occurs. Except in the case of a Default in payment on any Note (including the failure to make a mandatory repurchase pursuant hereto), the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in
good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
  
 SECTION 7.6. Reports by Trustee to Holder of the Notes. 
  
 Within 60 days after each May 15 beginning May 15, 2005, and for so long as Notes remain outstanding, the Trustee shall mail
to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be
transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c). 
  
 A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Issuer and filed with the Commission and each stock
exchange on which the Notes are listed in accordance with TIA § 313(d). The Issuer shall promptly notify the Trustee when the Notes are listed on any stock exchange or delisted therefrom. 
  

 -68- 








 SECTION 7.7. Compensation, Reimbursement and Indemnity. 
  
 The Issuer shall pay to the Trustee from time to time such compensation for
its acceptance of this Indenture and the rendering by it of the services required hereunder as shall be agreed upon in writing by the Issuer and the Trustee. The Trustee’s compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuer shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by or on behalf of it in addition to the compensation for its services. Such expenses
shall include the reasonable compensation, disbursements and expenses of the Trustee’s attorneys, accountants, experts and such other professionals as the Trustee deems necessary, advisable or appropriate. 
  
 The Issuer shall indemnify the Trustee and any predecessor Trustee and their
agents against any and all losses, liabilities, claims, damages or expenses, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture and any Mortgage (including its duties under Section 9.6 hereof), including the costs and expenses of enforcing this Indenture, any Guarantee or any Mortgage against the Issuer or a Guarantor
(including this Section 7.7) and defending itself against or investigating any claim (whether asserted by the Issuer, any Guarantor, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder or under any Mortgage, except to the extent any such loss, liability or expense is caused by its own negligence, willful misconduct or bad faith. The Trustee shall notify the Issuer promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend any claim or threatened claim asserted against the Trustee, and the Trustee shall cooperate in the defense.
The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
  
 The obligations of the Issuer under this Section 7.7 shall survive the
resignation or removal of the Trustee, the satisfaction and discharge of this Indenture and the termination of this Indenture and the release of any Mortgage. 
  

To secure the Issuer’s payment obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal, Redemption Price or Purchase Price of or Additional Interest, if any, or interest on, particular Notes. Such Lien shall survive the resignation or removal of the Trustee, the
satisfaction and discharge of this Indenture and the termination of this Indenture. 
  
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(f) or 6.1(g) hereof occurs, the expenses and the compensation for the services (including the reasonable fees and
expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
  
 SECTION 7.8. 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 7.8.

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

 (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;

Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction, in the case of the Trustee, at the expense of the Issuer, for the appointment of a successor Trustee. 
  
 If the Trustee, after written request by any Holder of a Note who has been a
bona fide holder of a Note or Notes for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

  
 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. 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 Issuer shall mail a notice of its succession to Holder of the Notes. 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 7.7 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

  
 SECTION 7.9. Successor Trustee by Merger,
Etc. 
  
 If the Trustee consolidates, merges or converts
into, or transfers all or substantially all of its corporate trust business to, another corporation or national association that is eligible under Section 7.10 hereof, the successor corporation or national association without any further act shall

 ARTICLE VIII 
  
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE

  
 SECTION 8.1. Option to Effect Legal
Defeasance or Covenant Defeasance. 
  
 The Issuer 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 8.2 or 8.3 hereof applied to all outstanding Notes upon compliance with the conditions set forth below
in this Article VIII. 
  
 SECTION 8.2. Legal
Defeasance and Discharge. 
  
 Upon the Issuer’s exercise
under Section 8.1 hereof of the option applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from its obligations with respect to all
outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to the “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in clauses (a) through (d) below, and
to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which
shall survive until otherwise terminated or discharged hereunder: 
  
 (a) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due; 
  
 (b) the Issuer’s obligations with respect to the Notes concerning issuing temporary Notes, registration
of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments; 
  
 (c) the rights, powers, trust, duties and immunities of the Trustee and the Issuer’s obligations in connection therewith; and

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

 -71- 








 Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2,
notwithstanding the prior exercise of its option under Section 8.3 hereof. 
  
 SECTION 8.3. Covenant Defeasance. 
  
 Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from
its obligations under the covenants contained in Sections 3.9, 3.10, 4.5, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13 (except with respect to the corporate existence of the Issuer), 4.14, 4.15, 4.16, 4.17, 4.18, 4.19, 4.21 and 5.1(a)(2) hereof with
respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that
such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer 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 6.1 hereof, but, except as specified above the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the
Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(c), 6.1(d), 6.1(e), 6.1(f), 6.1(h) and 6.1(i) hereof shall not
constitute Events of Default. 
  
 SECTION 8.4.
Conditions to Legal or Covenant Defeasance. 
  
 The
following are the conditions precedent to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes: 
  
 In order to exercise either Legal Defeasance or Covenant Defeasance: 
  
 (1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in
U.S. dollars, non-callable U.S. government obligations, 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, if any, and
interest on the Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be; 
  
 (2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably
acceptable to the Trustee confirming that: 
  
 (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling; or 
  
 (b) since the date of this Indenture, there has been a change in the applicable federal income tax law, 
  
 in either case to the effect that, and based thereon such opinion of counsel
shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred; 
  

 -72- 








 (3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an
Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or an Event of
Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings); 
  
 (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which the Issuer or any
of its Subsidiaries are a party or by which the Issuer or any of its Subsidiaries is bound; 
  
 (6) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with
the intent of preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuer or others; 
  
 (7) the Issuer shall have delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and 
  
 (8) the Issuer shall have delivered to the Trustee an
Opinion of Counsel to the effect that: 
  
 (a)
either (x) the Issuer has assigned all its ownership interest in the trust funds to the Trustee or (y) the Trustee has a valid perfected security interest in the trust funds; and 
  
 (b) assuming no intervening bankruptcy of the Issuer between the date of deposit and the 91st day following
the date of deposit and that no Holder is an insider of the Issuer, after the 91st day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors’ rights generally. 
  
 Notwithstanding
the foregoing, the Opinion of Counsel required by clause (2) above with respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due
and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer. 
  

 -73- 








 SECTION 8.5. Deposited Money and U.S. Government Securities to Be Held in Trust;
Other Miscellaneous Provisions. 
  
 Subject to Section 8.6
hereof, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5 only, the “Trustee”) pursuant to Section 8.4
hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (other than the Issuer) as
the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal or Redemption Price of, and Additional Interest, if any, interest on, the Notes, that such money need not be segregated from
other funds except to the extent required by law. 
  
 The Issuer
shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
  
 Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the request of the
Issuer any money or U.S. Government Securities held by it as provided in Section 8.4 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 8.4(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 8.6. Repayment to the Issuer. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by
the Issuer, in trust for the payment of the principal, Redemption Price or Purchase Price of, or Additional Interest, if any, or interest on any Note and remaining unclaimed for two years after such amount has become due and payable shall be paid to
the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuer for payment thereof as a general creditor, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such
repayment, at the expense of the Issuer, may cause to be published once, in The New York Times and The Wall Street Journal (national editions), notice that such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days after the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. 
  
 SECTION 8.7. Reinstatement. 
  
 If the Trustee or Paying Agent is unable to apply any United States dollars or U.S. Government Securities in accordance with
Section 8.2 or 8.3 hereof, as the case may be, by reason of any order of judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer under this Indenture, and
the Notes and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2
or 8.3 hereof, as the case may be; provided, however, that, if the Issuer makes any payment with respect to any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such
Notes to receive such payment from the money held by the Trustee or Paying Agent. 
  

 -74- 








 ARTICLE IX 
  
 AMENDMENT, SUPPLEMENT AND WAIVER 
  
 SECTION 9.1. Without Consent of Holders of Notes. 
  
 Notwithstanding Section 9.2 hereof, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the
Notes, any Collateral Document or any other agreement or instrument entered into by it in connection with this Indenture, the Notes or the Collateral Documents without the consent of any Holder of a Note: 
  
 (a) to cure any ambiguity, defect or inconsistency so long
as such change does not, in the opinion of the Trustee (which opinion may be formulated in reliance on such evidence as the Trustee deems appropriate, including, without limitation, solely on an opinion of counsel), adversely affect the rights of
any of the Holders in any material respect; 
  
 (b) to provide for uncertificated notes in addition to or in place of certificated Notes; 
  
 (c) to provide for the assumption of the Issuer’s obligations to the Holders of the Notes in the case of a merger or consolidation or
sale of all or substantially all of the Issuer’s assets pursuant to Article V hereof; 
  
 (d) to comply with the requirements of the Commission in order to effect or maintain the qualification of this Indenture under the TIA;

  
 (e) to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Notes; or 
  
 (f) to enter into a supplemental indenture to provide for the issuance of Additional Notes. 
  
 Upon the request of the Issuer, accompanied by a resolution of the Board
(evidenced by an Officers’ Certificate) authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Issuer in the
execution of any amended or supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter
into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
  
 SECTION 9.2. With Consent of Holders of Notes. 
  
 Except as provided below in this Section 9.2, the Issuer (and, if applicable, the Guarantors) and the Trustee may amend or
supplement this Indenture, the Notes, the Collateral Documents and any other agreement or instrument entered into by them in connection with this Indenture, the Notes or the Collateral Documents with the consent of the Holders of at least a majority
in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a tender offer or exchange offer for the Notes), and, subject to Sections 6.2, 6.4 and 6.7 hereof, any existing Default or Event
of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for the Notes). 
  

 -75- 








 Without the consent of (a) each Holder affected, an amendment or waiver may not (with respect to any
Notes held by a non-consenting Holder): 
  
 (1)
reduce the principal amount of Notes whose Holders must consent to an amendment; 
  
 (2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any
Notes; 
  
 (3) reduce the principal of or change
or have the effect of changing the fixed maturity of any Notes, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor; 
  
 (4) make any Notes payable in money other than that stated in the Notes; 
  
 (5) make any change in provisions of this Indenture
protecting the right of each Holder to receive payment of principal of and interest on such Holder’s Note or Notes on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal
amount of Notes to waive Defaults or Events of Default; 
  
 (6) after the Issuer’s obligation to purchase Notes arises hereunder, amend, change or modify in any material respect the obligation of the Issuer to make and consummate a Change of Control Offer in the event of
a Change of Control, or make and consummate a Net Proceeds Offer with respect to any Asset Sale that has been consummated or make and consummate a Loss Proceeds Offer with respect to any Event of Loss that has occurred or, after such Change of
Control has occurred, such Asset Sale has been consummated, or such Event of Loss has occurred, as the case may be, modify any of the provisions or definitions with respect thereto; 
  
 (7) modify or change any provision of this Indenture (or any definitions herein) affecting the ranking of
the Notes or any Guarantee in a manner that adversely affects the Holders; or 
  
 (8) release any Guarantee of a Guarantor that is a Significant Subsidiary from any of its obligations under its Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; and

  
 (b) the Holders of at least 75% in principal amount of the
Notes then outstanding, no amendment may release from the Lien of this Indenture or the Notes and the Collateral Documents all or substantially all of the Collateral otherwise than in accordance with the terms of such documents. 
  
 Upon the written request of the Issuer accompanied by a resolution of its
Board (evidenced by an Officers’ Certificate) authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Issuer in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
  

 -76- 








 It shall not be necessary for the consent of the Holders of Notes under this Section 9.2 to approve the
particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice
briefly describing the amendment, supplement or waiver. Any failure of the Issuer 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.

  
 SECTION 9.3. Compliance with Trust
Indenture Act. 
  
 Every amendment or supplement to this
Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect. 
  
 SECTION 9.4. Revocation and Effect of Consents. 
  
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by
the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or
subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in
accordance with its terms and therefore binds every Holder. 
  
 SECTION 9.5. Notation on or Exchange of Notes. 
  
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver. 
  
 Failure to
make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
  
 SECTION 9.6. Trustee to Sign Amendment, Etc. 
  
 The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or
supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment or supplemental Indenture until its Board of Directors approves such amendment or supplemental indenture. In
executing any amended or supplemental indenture, the Trustee shall be provided with, in addition to the documents required by Sections 15.4 and 15.5 hereof, and, subject to Section 7.1 hereof, shall be fully protected in relying upon, an
Officers’ Certificate and an Opinion of Counsel stating that (i) the execution of such amended or supplemental indenture is authorized or permitted by this Indenture, (ii) no Event of Default shall occur as a result of the execution of the
amended or supplemental indenture which is the subject of such Officers’ Certificate or the delivery of such Opinion of Counsel and (iii) the amended or supplemental indenture complies with the terms of this Indenture.

property from the Lien of the Collateral Documents and relating to the substitution therefor of any property to be subjected to the Lien of the Collateral Documents. Any certificate or opinion required by TIA § 314(d) may be made by an Officer
of the Issuer, except in cases where TIA § 314(d) requires that such certificate or opinion be made by an independent person, which person shall be an independent engineer, appraiser or other expert selected by the Issuer. 
  
 SECTION 10.6. Specified Releases of Collateral.

 ARTICLE XI 
  
 GUARANTEE 
  

	SECTION	11.1. Unconditional Guarantee. 

  
 Each Guarantor hereby unconditionally guarantees (such guarantee to be referred to herein as a “Guarantee”), on a senior basis jointly
and severally, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, the Notes or the obligations of the Issuer hereunder or thereunder, that: (i) the principal of and interest on the
Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration or otherwise and interest on the overdue principal, if any, and interest on any interest, to the extent lawful, of the Notes
and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or
renewal of any Notes or of any such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by
acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 11.3 hereof. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment
against the Issuer, and action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court 
  

 -84- 








 in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer,
protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and in this Guarantee. If any Holder or the Trustee is
required by any court or otherwise to return to any Issuer, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by the Issuer or any Guarantor to the
Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of
the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the
purpose of this Guarantee. 
  
 In connection with any Guarantee
(whether issued on or after the Issue Date), the Issuer will use its best efforts to obtain all necessary governmental or regulatory approval relating to the authorization, execution, delivery or enforcement of such Guarantee. 
  

	SECTION	11.2. Severability. 

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

	SECTION	11.3. Limitation of Guarantor’s Liability. 

  
 Each Guarantor and by its acceptance hereof each Holder hereby confirms that it is the intention of all such parties that the guarantee by such Guarantor
pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the
foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the obligations of such Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities
of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to Section 11.5 hereof, result in the
obligations of such Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance. 
  

	SECTION	11.4. Release of Guarantor. 

  
 (a) The Guarantee and any obligations of a Guarantor under any Collateral Document to which it is a party and any Lien created by such Guarantor under any
such Collateral Documents will be automatically and unconditionally released without any action on the part of the Trustee or the Holders of the Notes: (1) in connection with any sale or other disposition of all or substantially all of the assets of
that Guarantor (including, without limitation, by way of merger or consolidation), if the Issuer applies the Net Cash Proceeds of that sale or other disposition in accordance with the applicable provisions of this Indenture; (2) upon any sale,
exchange or transfer, to any Person not an Affiliate of the Issuer, of all of the Issuer’s Capital Stock in such Restricted Subsidiary made in compliance with the Collateral Documents, and if the Issuer applies the Net Cash Proceeds of that
sale in accordance with the applicable provisions of this Indenture; (3) if the Issuer designates that Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture and such Restricted Subsidiary is released
from all guarantees, if any, by it of other Indebtedness of the Issuer or any Restricted Subsidiary; or (4) upon the payment in full of the Notes. 
  

 -85- 








 In addition, concurrently with any Legal Defeasance or Covenant Defeasance, the Guarantors shall be
released from all of their Obligations under their respective applicable Guarantees. 
  
 (b) The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Issuer accompanied by an Officers’ Certificate and Opinion of Counsel certifying as to the
compliance with this Section 11.4. 
  

	SECTION	11.5. Contribution. 

  
 In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a “Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount based on the Adjusted Net Assets (as
defined below) of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Issuer’s obligations with respect to the Securities or any other Guarantor’s
obligations with respect to the Guarantee. “Adjusted Net Assets” of such Guarantor at any date shall mean the lesser of the amount by which (x) the fair value of the property of such Guarantor exceeds the total amount of
liabilities, including, without limitation, contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date), but excluding liabilities under the Guarantee, of such Guarantor at such date
and (y) the present fair salable value of the assets of such Guarantor at such date exceeds the amount that will be required to pay the probable liability of such Guarantor on its debts (after giving effect to all other fixed and contingent
liabilities incurred or assumed on such date), excluding debt in respect of the Guarantee of such Guarantor, as they become absolute and matured. 
  

	SECTION	11.6. Waiver of Subrogation. 

  
 Until all Obligations are paid in full, each Guarantor hereby irrevocably waives any claims or other rights which it may now or hereafter acquire against
the Issuer that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under the Guarantee and this Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration,
indemnification, and any right to participate in any claim or remedy of any Holder against the Issuer, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to
take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the
preceding sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Holders, and shall, forthwith be paid to the
Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.6 is knowingly made in contemplation of such benefits. 
  

	SECTION	11.7. Execution of Guarantee. 

  
 To evidence their guarantee to the Holders set forth in this Article XI, the Guarantors hereby agree to execute the Guarantee in substantially the form
attached hereto as Exhibit C, which shall be endorsed on each Note ordered to be authenticated and delivered by the Trustee. Each Guarantor 
  

 -86- 








 hereby agrees that its Guarantee set forth in this Article XI shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Guarantee. Each such Guarantee shall be signed on behalf of each Guarantor by one of its authorized Officers prior to the authentication of the Note on which it is endorsed, and the delivery of such
Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of such Guarantee on behalf of such Guarantor. Such signatures upon the Guarantee may be by manual or facsimile signature of such officers and may be
imprinted or otherwise reproduced on the Guarantee, and in case any such officer who shall have signed the Guarantee shall cease to be such officer before the Note on which such Guarantee is endorsed shall have been authenticated and delivered by
the Trustee or disposed of by the Issuer, such Note nevertheless may be authenticated and delivered or disposed of as though the Person who signed the Guarantee had not ceased to be such officer of the Guarantor. 
  

	SECTION	11.8. Waiver of Stay, Extension or Usury Laws. 

  
 Each Guarantor covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive each such Guarantor from performing its Guarantee as contemplated herein, wherever enacted, now or at any time hereafter in
force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each such Guarantor hereby expressly waives all benefit or advantage of any such law, and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

payment and to apply such amount to the payment that is due. If the amounts so deposited by the Issuer and its Restricted Subsidiaries into the Collateral Account under this Section 13.4(a) prove insufficient to pay the amounts required to be
discharged by the Issuer, then, upon demand, the Issuer shall pay directly to the Trustee for deposit into the Collateral Account such additional amounts. In the event that the Notes become immediately due and payable upon maturity or acceleration,
or the Collateral becomes enforceable otherwise, the Trustee may apply all or any part of the sums held pursuant to this Section 13.4(a) to payment and performance of the Issuer’s obligations in accordance with this Indenture and the applicable

material Permits now or hereafter required by any Authority (including, without limitation, building ordinances and codes and zoning requirements) to operate or use and occupy the Mortgaged Properties for their intended uses, except in such cases
where the failure to maintain such Permits would not have a material adverse effect on the condition, use, operation or value of such Mortgaged Property. 
  

	SECTION	13.5. Environmental Matters. 

  
 (a) The Issuer shall ensure, and shall cause each of its Restricted Subsidiaries that owns a Mortgaged Property to ensure, that the condition of all
Mortgaged Property is in compliance in all material respects with Environmental Laws, except where the failure to be in such compliance will not result in a material adverse effect on the condition, use, operation or value of such Mortgaged
Property. 
  
 (b) The Issuer shall, and shall cause each of its
Restricted Subsidiaries that owns a Mortgaged Property to, diligently undertake any Remedial Action required under Environmental Laws in the event of (i) any violation of any Environmental Laws or (ii) any Release on any Mortgaged Property forming
part of the Collateral or owned by the Issuer or its Restricted Subsidiaries; provided, however, that the Issuer and such of its Restricted Subsidiaries shall have no obligations under this paragraph (b) to the extent any of them is
diligently prosecuting a defense or other legal challenge to any alleged liability or requirement for Remedial Action, or except where the failure to undertake the Remedial Action will not result in a material adverse effect on the condition, use,
operation or value of such Mortgaged Property. 
  
 (c) The Issuer
hereby undertakes, to the extent permitted by applicable law, to indemnify the Holders, as well as the Trustee, their officers, directors, employees, agents and shareholders, and agrees to hold each of them harmless from and against any and all

 (ii) any cost, liability or damage arising out of the

Subsidiaries to comply with any Environmental Laws.

satisfaction of the Issuer’s obligations under the Notes, and its release from all other obligations under this Indenture and the Collateral Documents. Notwithstanding the foregoing, the indemnity provided by the Issuer and its Restricted
Subsidiaries pursuant to this Section 13.5(e) shall not apply to any liabilities or costs caused by the negligence, willful misconduct or bad faith of the Trustee.
