All Notes shall be dated the date of their authentication.

SECTION 2.02. Registration of Transfer and Exchange of Notes. (a) The Issuers may, at their own expense, appoint any Person with appropriate experience as a securities registrar to act as Note Registrar hereunder; provided that in the absence of any other Person appointed in accordance herewith acting as Note Registrar, the Indenture Trustee agrees to act in such capacity in accordance with the terms hereof. The Note Registrar shall be subject to the same standards of care, limitations on liability and rights to indemnity as the Indenture Trustee, and the provisions of Sections 11.01, 11.02, 11.03, 11.04, 11.05(b), and 11.05(c) shall apply to the Note Registrar to the same extent

that they apply to the Indenture Trustee and the same rights of recovery.

The Issuers may at any time terminate the agency of any Note Registrar appointed in accordance with this Section 2.02(a) by giving written notice of termination to such Note Registrar, with a copy to the Servicer and the Indenture Trustee.

At all times during the term of this Indenture, there shall be maintained at the office of the Note Registrar a Note Register in which, subject to such reasonable regulations as the Note Registrar may prescribe, the Note Registrar shall provide for the registration of Notes and of transfers and exchanges of Notes as herein provided. The Issuers, the Servicer and the Indenture Trustee shall have the right to inspect the Note Register or to obtain a copy thereof at all reasonable times, and to rely conclusively upon a certificate of the Note Registrar as to the information set forth in the Note Register.

Upon written request of any Noteholder of record made for purposes of communicating with other Noteholders with respect to their rights under the Indenture (which request must be accompanied by a copy of the communication that the Noteholder proposes to transmit), the Note Registrar, within 30 days after the receipt of such request, must afford the requesting Noteholder access during normal business hours to, or deliver to the requesting Noteholder a copy of, the most recent list of Noteholders held by the Note Registrar. Every Noteholder, by receiving such access, agrees with the Note Registrar and the Indenture Trustee that neither the Note Registrar nor the Indenture Trustee shall be held accountable in any way by reason of the disclosure of any information as to the names and addresses of any Noteholder, regardless of the source from which such information was derived.

(b) No transfer, sale, pledge or other disposition of any Note or interest therein shall be made unless that transfer, sale, pledge or other disposition is exempt from the registration and/or qualification requirements of the Securities Act and any applicable state securities laws, or is otherwise made in accordance with the Securities Act and such state securities laws.

If a transfer of any Note that constitutes a Definitive Note is to be made without registration under the Securities Act (other than in connection with the initial issuance of the Notes or a transfer of a Book-Entry Note to a successor Depositary as contemplated by Section 2.03(c)), then the Note Registrar shall refuse to register such transfer unless it receives (and, upon receipt, may conclusively rely upon) either: (i) a certificate from the Noteholder desiring to effect such transfer substantially in the form attached hereto as Exhibit C-5 or Exhibit C-6 and a certificate from the prospective Transferee substantially in the form attached hereto as Exhibit C-3 or Exhibit C-4; or (ii) an Opinion of Counsel satisfactory to the Note Registrar to the effect that such transfer may be made without registration under the Securities Act (which Opinion of Counsel shall not be an expense of the Issuers, the Servicer, the Indenture Trustee or the Note Registrar in their respective capacities as such), together with the written certification(s) as to the facts surrounding such transfer from the Noteholder desiring to effect such transfer and/or such Noteholder’s prospective Transferee on which such Opinion of Counsel is based.

If a transfer of any interest in a Rule 144A Global Note is to be made without registration under the Securities Act (other than in connection with the initial issuance of the Book-Entry Notes), then the Note Owner desiring to effect such transfer shall be required to obtain either (i) a certificate from such Note Owner’s prospective Transferee substantially in the form attached as Exhibit C-1 hereto, or (ii) an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Issuers, the Servicer, the Indenture Trustee or the Note Registrar in their respective capacities as such), to the effect that such transfer may be made without registration under the Securities Act. Except as provided in the following two paragraphs, no interest in a Rule 144A Global Note for any Class of Book-Entry Notes shall be transferred to any Person who takes delivery other than in the form of an interest in such Rule 144A Global Note. If any Transferee of an interest in a Rule 144A Global Note for any Class of Book-Entry Notes does not, in connection with the subject Transfer, deliver to the Transferor the Opinion of Counsel or the certification described in the second preceding sentence, then such Transferee shall be deemed to have represented and warranted that all the certifications set forth in Exhibit C-1 hereto are, with respect to the subject Transfer, true and correct.

Notwithstanding the preceding paragraph, any interest in a Rule 144A Global Note for a Class of Book-Entry Notes may be transferred (without delivery of any certificate or Opinion of Counsel described in clauses (i) and (ii) of the first sentence of the preceding paragraph) by any Person designated in writing by the Issuers to any Person who takes delivery in the form of a beneficial interest in a Regulation S Global Note for such Class of Notes upon delivery to the Note Registrar of such written orders and instructions as are required under the Applicable Procedures of the Depositary, Clearstream and Euroclear to direct the Indenture Trustee to debit the account of a DTC Participant by a denomination of interests in such Rule 144A Global Note, and credit the account of a DTC Participant by a denomination of interests in such Regulation S Global Note, that is equal to the denomination of beneficial interests in the Class of Notes to be transferred. Upon delivery to the Note Registrar of such orders and instructions, the Indenture Trustee, subject to and in accordance with the Applicable Procedures of the Depositary, shall reduce the denomination of the Rule 144A Global Note in respect of the applicable Class of Notes and increase the denomination of the Regulation S Global Note for such Class by the denomination of the beneficial interest in such Class specified in such orders and instructions.

Also notwithstanding the foregoing, any interest in a Rule 144A Global Note with respect to any Class of Book-Entry Notes may be transferred by any Note Owner holding such interest to any Institutional Accredited Investor (other than a Qualified Institutional Buyer) that takes delivery in the form of a Definitive Note of the same Class as such Rule 144A Global Note upon delivery to the Note Registrar and the Indenture Trustee of (i) such certifications and/or opinions as are contemplated by the second paragraph of this Section 2.02(b) and (ii) such written orders and instructions as are required under the Applicable Procedures of the Depositary to direct the Indenture Trustee to debit the account of a DTC Participant by the denomination of the transferred

interests in such Rule 144A Global Note. Upon delivery to the Note Registrar of the certifications and/or opinions contemplated by the second paragraph of this Section 2.02(b), the Indenture Trustee, subject to and in accordance with the Applicable Procedures of the Depositary, shall reduce the denomination of the subject Rule 144A Global Note by the denomination of the transferred interests in such Rule 144A Global Note, and shall cause a Definitive Note of the same Class as such Rule 144A Global Note, and in a denomination equal to the reduction in the denomination of such Rule 144A Global Note, to be executed, authenticated and delivered in accordance with this Indenture to the applicable Transferee.

Except as provided in the next paragraph, no beneficial interest in a Regulation S Global Note for any Class of Book-Entry Notes shall be transferred to any Person who takes delivery other than in the form of a beneficial interest in such Regulation S Global Note. On and prior to the Release Date, a Note Owner desiring to effect any such Transfer shall be required to obtain from such Note Owner’s prospective Transferee a written certification substantially in the form set forth in Exhibit C-2 hereto certifying that such Transferee is not a U.S. Person. On or prior to the Release Date, beneficial interests in the Regulation S Global Note for each Class of Book-Entry Notes may be held only through Euroclear or Clearstream. The Regulation S Global Note for each Class of Book-Entry Notes shall be deposited with the Indenture Trustee as custodian for the Depositary and registered in the name of Cede & Co. as nominee of the Depositary.

Notwithstanding the preceding paragraph, after the Release Date, any interest in a Regulation S Global Note for a Class of Book-Entry Notes may be transferred to any Person designated in writing by the Issuers to any Person who takes delivery in the form of a beneficial interest in the Rule 144A Global Note for such Class of Notes upon delivery to the Note Registrar of such written orders and instructions as are required under the Applicable Procedures of the Depositary, Clearstream and Euroclear to direct the Indenture Trustee to debit the account of a DTC Participant by a denomination of interests in such Regulation S Global Note, and credit the account of a DTC Participant by a denomination of interests in such Rule 144A Global Note, that is equal to the denomination of beneficial interests in the Class of Notes to be transferred. Upon delivery to the Note Registrar of such orders and instructions, the Indenture Trustee, subject to and in accordance with the Applicable Procedures of the Depositary, shall reduce the denomination of the Regulation S Global Note in respect of the applicable Class of Notes and increase the denomination of the Rule 144A Global Notes for such Class by the denomination of the beneficial interest in such Class specified in such orders and instructions.

None of the Issuers, the Guarantor, the Indenture Trustee or the Note Registrar shall be obligated to register or qualify any Class of Notes under the Securities Act or any other applicable state securities law or to take any action not otherwise required under this Indenture to permit the transfer of any Note or interest therein without registration or qualification. Any Noteholder or Note Owner desiring to effect a transfer, sale, pledge or other disposition of any Note or interest therein shall, and, by its acceptance of its Notes or interest therein, does hereby agree to, indemnify the Issuers,

the Initial Purchasers, the Indenture Trustee, the Manager, the Servicer and the Note Registrar against any liability that may result if such transfer, sale, pledge or other disposition is not exempt from the registration and/or qualification requirements of the Securities Act and any applicable state securities laws or is not made in accordance with such Federal and state laws.

(c) No transfer of any Note or interest therein shall be made (A) to any retirement plan or other employee benefit plan (as defined in Section 3(31) of ERISA), including individual retirement accounts and annuities, Keogh plans and collective investment funds, insurance company separate accounts and certain insurance company general accounts in which such plans, accounts or arrangements are invested, that is subject to Title I of ERISA, or Section 4975 of the Code or any plan, individual retirement account or other arrangement that is subject to any Federal, state or local law or Non-U.S. law that is substantially similar to Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) (each, a “Plan”), or (B) to any Person who is directly or indirectly acquiring such Note or such interest therein on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan, if the acquisition and holding of such Note or interest therein described in clauses (A) or (B) by the prospective Transferee would result in a violation of Section 406 of ERISA or Section 4975 of the Code or would result in a civil penalty under ERISA or in the imposition of an excise tax under Section 4975 of the Code or is otherwise in violation of any Similar Law. No transfer of any Note shall be made to any Plan or to any Person who is directly or indirectly acquiring such Note on behalf of, as fiduciary of, as trustee of, or with the assets of, a Plan, unless the purchase and holding of such Note or interest therein by such Plan or Person are exempt from the prohibited transaction restrictions of ERISA and the Code or any Similar Law pursuant to one or more prohibited transaction statutory or administrative exemptions. Any attempted or purported transfer of a Note in violation of this Section 2.02(c) shall be null and void and vest no rights in any purported Transferee.

The Note Registrar shall refuse to register the transfer of a Note that constitutes a Definitive Note or a transfer of an interest in a Book-Entry Note that following such purported transfer shall constitute a Definitive Note, unless it has received from the prospective Transferee either:

(i) a certification or deemed representation, as applicable, to the effect that such prospective Transferee is not a Plan and is not directly or indirectly acquiring such Note on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan; or

(ii) a certification or deemed representation, as applicable, that such transfer and holding by such Transferee are exempt from the prohibited transaction restrictions of ERISA and the Code or materially similar provisions under similar law pursuant to one or more prohibited transaction statutory or administrative exemptions.

It is hereby acknowledged that either of the forms of certification attached hereto as Exhibits C-3 and C-4 is acceptable for purposes of clauses (i) and (ii) of the preceding sentence.

The Note Owner desiring to effect a transfer of an interest in a Book-Entry Note (other than a transfer of an interest in a Book-Entry Note that following such purported transfer shall constitute a Definitive Note) shall obtain from its prospective Transferee either:

(i) a certification or deemed representation, as applicable, to the effect that such prospective Transferee is not a Plan and is not directly or indirectly acquiring such interest in such Note on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan; or

It is hereby acknowledged that either of the forms of certification attached hereto as Exhibits C-1 and C-2 is acceptable for purposes of clauses (i) and (ii) of the preceding sentence.

(d) If a Person is acquiring a Note as a fiduciary or agent for one or more accounts, such Person shall be required to deliver to the Note Registrar a certification to the effect that, and such other evidence as may be reasonably required by the Note Registrar to confirm that, it has (i) sole investment discretion with respect to each such account and (ii) full power to make the applicable foregoing acknowledgments, representations, warranties, certifications and/or agreements with respect to each such account as set forth in subsections (b), (c) and/or (d), as appropriate, of this Section 2.02.

(e) Subject to the preceding provisions of this Section 2.02, upon surrender for registration of transfer of any Note at the offices of the Note Registrar maintained for such purpose, one or more new Notes of authorized denominations of the same Class evidencing a like aggregate Percentage Interest shall be executed, authenticated and delivered, in the name of the designated transferee or transferees, in accordance with Section 2.01(b).

(f) At the option of any Noteholder, its Notes may be exchanged for other Notes of authorized denominations of the same Class evidencing a like aggregate Percentage Interest, upon surrender of the Notes to be exchanged at the offices of the Note Registrar maintained for such purpose. Whenever any Notes are so surrendered for exchange, the Notes which the Noteholder making the exchange is entitled to receive shall be executed, authenticated and delivered in accordance with Section 2.01(b).

(g) Every Note presented or surrendered for transfer or exchange shall (if so required by the Note Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Note Registrar duly executed by, the Noteholder thereof or his attorney duly authorized in writing.

(h) No service charge shall be imposed for any transfer or exchange of Notes, but the Indenture Trustee or the Note Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Notes.

(i) All Notes surrendered for transfer and exchange shall be physically canceled by the Note Registrar, and the Note Registrar shall dispose of such canceled Notes in accordance with its standard procedures.

SECTION 2.03. Book-Entry Notes. (a) Each Class of Notes shall initially be issued as one or more Notes registered in the name of the Depositary or its nominee and, except as provided in Section 2.03(c), transfer of such Notes may not be registered by the Note Registrar unless such transfer is to a successor Depositary that agrees to hold such Notes for the respective Note Owners with Ownership Interests therein. Such Note Owners shall hold and, subject to Sections 2.02(b) and 2.02(c), transfer their respective ownership interests in and to such Notes through the book-entry facilities of the Depositary and, except as provided in Section 2.03(c) below, shall not be entitled to Definitive Notes in respect of such ownership interests. Notes of each Class of Notes initially sold in reliance on Rule 144A shall be represented by the Rule 144A Global Note for such Class, which shall be deposited with the Indenture Trustee as custodian for the Depositary and registered in the name of Cede & Co. as nominee of the Depositary. Notes of each Class of Notes initially sold in offshore transactions in reliance on Regulation S shall be represented by the Regulation S Global Note for such Class, which shall be deposited with the Indenture Trustee as custodian for the Depositary. All transfers by Note Owners of their respective ownership interests in the Book-Entry Notes shall be made in accordance with the procedures established by the DTC Participant or brokerage firm representing each such Note Owner. Each DTC Participant shall only transfer the ownership interests in the Book-Entry Notes of Note Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depositary’s normal procedures.

(b) The Issuers, the Servicer, the Indenture Trustee and the Note Registrar shall for all purposes, including the making of payments due on the Book-Entry Notes, deal with the Depositary as the authorized representative of the Note Owners with respect to such Notes for the purposes of exercising the rights of Noteholders hereunder. The rights of Note Owners with respect to the Book-Entry Notes shall be limited to those established by law and agreements between such Note Owners and the DTC Participants and indirect participating brokerage firms representing such Note Owners. Multiple requests and directions from, and votes of, the Depositary as holder of the Book-Entry Notes with respect to any particular matter shall not be deemed inconsistent if they are made with respect to different Note Owners. The Indenture Trustee may establish a reasonable record date in connection with solicitations of consents from or voting by Noteholders and shall give notice to the Depositary of such record date.

(c) Notes initially issued in book-entry form shall thereafter be issued as Definitive Notes to applicable Note Owners or their nominees, rather than to DTC or its nominee, only (i) if the Issuers advise the Indenture Trustee in writing that DTC is no longer willing or able to properly discharge its responsibilities as Depositary with respect to such Notes and the Issuers are unable to locate a qualified successor or (ii) in connection with the transfer by a Note Owner of an interest in a Global Note to an Institutional Accredited Investor that is not a Qualified Institutional Buyer. Upon the occurrence of the event described in clause (i) of the preceding sentence, the Indenture Trustee shall be required to notify, in accordance with DTC’s procedures, all DTC Participants (as identified in a listing of DTC Participant accounts to which each Class of Book-Entry Notes is credited) through DTC of the availability of such Definitive Notes. Upon surrender to the Note Registrar of any Class of Book-Entry Notes (or any portion of any Class thereof) by the Depositary, accompanied by re-registration instructions from the Depositary for registration of transfer, Definitive Notes in respect of such Class (or portion thereof) shall be executed and authenticated in accordance with Section 2.01(b) and delivered to the Note Owners identified in such instructions. None of the Issuers, the Servicer, the Indenture Trustee or the Note Registrar shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Notes for purposes of evidencing ownership of any Book-Entry Notes, the registered holders of such Definitive Notes shall be recognized as Noteholders hereunder and, accordingly, shall be entitled directly to receive payments on, to exercise Voting Rights with respect to, and to transfer and exchange such Definitive Notes.

SECTION 2.04. Mutilated, Destroyed, Lost or Stolen Notes. If (i) any mutilated Note is surrendered to the Note Registrar, or the Note Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the Issuers, the Indenture Trustee and the Note Registrar such security or indemnity as may be reasonably required by them to hold each of them harmless, then, in the absence of actual notice to a Responsible Officer of the Issuers, Indenture Trustee or the Note Registrar that such Note has been acquired by a bona fide purchaser, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note of the same Class and Series and like Percentage Interest shall be executed, authenticated and delivered in accordance with Section 2.01(b). Upon the issuance of any new Note under this Section 2.04, the Issuers, the Indenture Trustee and the Note Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Indenture Trustee and the Note Registrar) connected therewith. Any replacement Note issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership such Note, as if originally issued, whether or not the lost, stolen or destroyed Note shall be found at any time. In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Note, pay such Note.

The provisions of this Section 2.04 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.05. Persons Deemed Owners. Prior to due presentment for registration of transfer, the Issuers, the Servicer, the Indenture Trustee and any agent of any of them may treat the Person in whose name any Note is registered as the owner of such Note on the Note Registrar for the purpose of receiving payments pursuant to Section 5.01 and for all other purposes whatsoever, and none of the Issuers, the Servicer, the Indenture Trustee, the Note Registrar or any agent of any of them shall be affected by notice to the contrary.

SECTION 2.06. Certification by Note Owners. (a) Each Note Owner is hereby deemed, by virtue of its acquisition of an ownership interest in the Book-Entry Notes, to agree to comply with the transfer requirements of Section 2.02(c).

(b) To the extent that under the terms of this Indenture, it is necessary to determine whether any Person is a Note Owner, the Indenture Trustee shall make such determination based on a certificate of such Person in such form as shall be reasonably acceptable to the Indenture Trustee and shall specify the Class, Series and Note Principal Balance of the Book-Entry Note beneficially owned; provided, however, that none of the Indenture Trustee or the Note Registrar shall knowingly recognize such Person as a Note Owner if such Person, to the actual knowledge of a Responsible Officer of the Indenture Trustee or the Note Registrar, as the case may be, acquired its ownership interest in a Book-Entry Note in violation of Section 2.02(c), or if such Person’s certification that it is a Note Owner is in direct conflict with information known by, or made known to, a Responsible Officer of the Indenture Trustee or the Note Registrar, with respect to the identity of a Note Owner. The Indenture Trustee and the Note Registrar shall each exercise its reasonable discretion in making any determination under this Section 2.06(b) and shall afford any Person providing information with respect to its Note Ownership of any Book-Entry Note an opportunity to resolve any discrepancies between the information provided and any other information available to the Indenture Trustee or the Note Registrar, as the case may be. If any request would require the Indenture Trustee to determine the Beneficial Owner of any Note, the Indenture Trustee may condition its making such a determination on the payment by the applicable Person of any and all costs and expenses incurred or reasonably anticipated to be incurred by the Indenture Trustee in connection with such request or determination.

SECTION 2.07. Issuable in Series. The Notes may be issued in one or more Series and one or more Classes of such Series. There shall be established in one or more Indenture Supplements, prior to the issuance of Notes of any Class of any Series,

(i) the title of the Notes of such Class of such Series (which shall distinguish the Notes of such Class of such Series from all other Notes);

(ii) any limit upon the aggregate principal balance of the Notes of such Class of such Series that may be authenticated and delivered under this Indenture (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes of such Class of such Series pursuant to Section 2.04 or 2.06);

(iii) the date or dates on which the principal of the Notes of such Class of such Series is payable;

(iv) the rate or rates at which the Notes of such Class of such Series shall bear interest, if any, or the method by which such rate shall be determined, the date or dates from which such interest shall accrue, the interest payment dates on which such interest shall be payable and the record dates for the determination of Holders to whom interest is payable; and

(v) any other terms of such Class of such Series.

SECTION 2.08. Cancellation. The Issuers at any time may deliver Notes to the Indenture Trustee for cancellation. The Note Registrar and the Paying Agent shall forward to the Indenture Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Indenture Trustee shall cancel all Notes surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy such canceled Notes (subject to the record retention requirement of the Exchange Act) and deliver a certificate of such destruction to the Issuers, unless the Issuers otherwise direct. Except as set forth in Section 2.11, the Issuers may not issue new Notes to replace Notes that it has paid or delivered to the Indenture Trustee for cancellation.

(b) In connection with each disposition of a Tower Site or Owned Fee Tower Site, as the case may be, permitted by Section 7.32 or 7.34, the Issuers shall prepay the Notes in an amount equal to the Release Price for such disposed Tower Site or Owned Fee Tower Site, as the case may be, together with (1) accrued and unpaid interest, if any, to the prepayment date and (2) the applicable Prepayment Consideration if such prepayment of any Class of Notes occurs more

than six months prior to the Applicable Maturity Date of the Notes being prepaid; provided that the Issuers shall not dispose of a Tower Site unless either (1) after giving pro forma effect to the receipt of proceeds in connection such disposition, (A) the DSCR shall be greater than 1.30 and (B) following such disposition at least 78% of the Operating Revenues of the Tower Sites that remain following such disposition consists of wireless voice or data revenues; or (2) Rating Agency Confirmation is obtained with respect to the Notes from each Rating Agency. Such prepayments first will be allocated or distributed pursuant to Section 5.01, items first through seventh, and then be applied to reduce the Class Principal Balance of the Class A Notes on a pro rata basis until the Class Principal Balance of the Class A Notes is reduced to zero, and then to reduce the Class Principal Balance of any Notes having a later alphabetical designation than the Class A Notes, sequentially in alphabetical order, until the Class Principal Balance of each such Class of Notes is, in turn, reduced to zero.

SECTION 2.10. Defeasance. (a) At any time prior to the Payment Date that is six months prior to the Applicable Maturity Date of the Class of Notes having the latest maturity, the Issuers may (upon 30 days’ written notice to the Indenture Trustee) obtain the release from all covenants under this Indenture relating to ownership and operation of the Tower Sites by defeasing all of the Notes then outstanding with U.S. government securities that provide for payments which replicate the required payments

The new entity shall assume the obligations of the Issuers under the Notes, the security agreement and the Transaction Documents and the Issuers shall be relieved of their obligations thereunder. The Issuers shall pay $10 to such new entity as consideration for assuming such obligations of the Issuers.

Without limiting the foregoing, upon and at all times after the occurrence and during the continuance of an Event of Default, the Indenture Trustee at the written direction of the Servicer (in its sole and absolute discretion, but subject to the Servicing Standard) may use the Reserves (or any portion thereof) for any purpose, including, but not limited to any combination of the following: for (i) payment against of the Obligations including the Prepayment Consideration (if any) applicable upon such payment in such order as the Servicer may determine in its sole discretion; provided, however, that such application of funds shall not cure or be deemed to cure any default; and provided, further, that any payments on the Notes shall be made in accordance with the priorities set forth in Section 5.01; (ii) reimbursement of the Indenture Trustee and Servicer for any actual losses or expenses (including, without limitation, reasonable legal fees) suffered or incurred as a result of such Event of Default; (iii) payment for the work or obligation for which such Reserves were reserved or were required to be reserved; and (iv) application of the Reserves in connection with the exercise of any and all rights and remedies available to the Servicer acting on behalf of the Indenture Trustee at law or in equity or under this Indenture or pursuant to any of the other Transaction Documents.

SECTION 4.02. Funds Deposited with Indenture Trustee. (a) Permitted Investments; Return of Reserves to Issuers. Except only as expressly provided otherwise herein, all funds of the Issuers which are deposited with Central Account Bank as Reserves hereunder shall be held by Central Account Bank in one or more Permitted Investments at the direction of the Issuers in accordance with the Cash Management Agreement. After repayment of all of the Obligations, all funds held as Reserves shall be promptly returned to, or as directed by, the Issuers.

(b) Funding at Closing. The Issuers shall deposit with the Indenture Trustee the amounts necessary to fund each of the Reserves as set forth below. Deposits into the Reserves on the Closing Date may occur by deduction from the amount of proceeds of the issuance of the Notes that otherwise would be disbursed to the Issuers, followed by deposit of the same into the applicable Sub-Account or Accounts of the Central Account in accordance with the Cash Management Agreement on the Closing Date. Notwithstanding such deductions, the Notes shall be deemed for all purposes to be fully paid for on the Closing Date.

SECTION 4.03. Impositions and Insurance Reserve. On the Closing Date, the Issuers shall deposit with the Central Account Bank $650,000 in the Impositions and Insurance Reserve Sub-Account and, pursuant to this Indenture and the Cash Management Agreement, the Indenture Trustee shall deposit in the Impositions and Insurance Reserve Sub-Account, on each Payment Date commencing on the Payment Date in September 15, 2009, 1/12th of the annual charges (as reasonably estimated by the Servicer based on advice from the Manager) for all Impositions and all Insurance Premiums (provided that any amounts in respect of blanket policies shall include only that portion of Insurance Premiums allocated to the coverage provided for the Tower Sites) payable with respect to the Tower Sites hereunder (said funds, together with any interest thereon and additions thereto, the “Impositions and Insurance Reserve”). The

initial amount of the monthly deposit to be made to the Impositions and Insurance Reserve from and after the date hereof is $650,000. If at any time the Manager reasonably determines that the amount in the Impositions and Insurance Reserve Sub-Account shall not be sufficient to pay the Impositions and Insurance Premiums when due, the Indenture Trustee shall increase the monthly deposits by the amount that the Manager estimates is sufficient to make up the deficiency and, in such instance, the Issuers shall deposit with the Central Account Bank within 10 Business Days of a written demand by the Indenture Trustee, to be added to and included within such Reserve, a sum of money which the Servicer has determined (in reliance on the Manager’s written request), together with such monthly deposits, shall be sufficient to make the payment of each such charge (but, with respect to blanket policies, only that portion of the Insurance Premiums allocated to the coverage provided for the Issuers and the Tower Sites) at least 10 Business Days prior to the date initially due. The Issuers shall provide the Indenture Trustee (with copies delivered simultaneously to the Servicer) with bills or a statement of amounts due for the next calendar month which shall be accompanied by an Officer’s Certificate and such other documents as may be reasonably required to establish the amounts required to be paid in the following calendar month at least five days prior to the date on which each payment shall first become subject to penalty or interest if not paid, or if paid, copies of paid bills. So long as (i) no Event of Default has occurred and is continuing, (ii) the Issuers have provided the Indenture Trustee and the Servicer with the foregoing materials in a timely manner, and (iii) sufficient funds are held by the Indenture Trustee for the payment of the Impositions and Insurance Premiums relating to the Tower Sites, as applicable, the Indenture Trustee shall, at the Manager’s election and written direction, with written notice simultaneously delivered to the Servicer, (x) pay said items, (y) disburse to the Issuers or the Manager from such Reserve an amount sufficient to pay said items, or (z) reimburse the Issuers for items previously paid by the Issuers or the Manager, as applicable. Interest shall accrue in favor of the Issuers on funds in the Impositions and Insurance Reserve.

SECTION 4.04. Advance Rents Reserve. On the Closing Date, the Issuers shall deposit with the Central Account Bank $2,970,000 and, pursuant to the Cash Management Agreement, the Issuers shall instruct the Indenture Trustee to deposit, (i) the Annual Advance Rents Reserve Deposit, (ii) the Semi-Annual Advance Rents Reserve Deposit and (iii) the Quarterly Advance Rents Reserve Deposit (with the amounts deposited pursuant to clauses (i), (ii) and (iii) subject to adjustment based on the late payments made by Tenants), into a Sub-Account of the Central Account (said Sub-Account, the “Advance Rents Reserve Sub-Account”, and said funds, the “Advance Rents Reserve”) for deposit of such Advance Rents Reserve Deposit. Such Advance Rents Reserve Deposit shall be held, allocated and disbursed in accordance with the terms and conditions of the Cash Management Agreement.

SECTION 4.05. Cash Trap Reserve. If a Cash Trap Condition shall occur, then, from and after the date that it is determined that a Cash Trap Condition has occurred (which shall be based upon the financial reporting required to be delivered pursuant to Section 7.02(a)(iv)) and for so long as such Cash Trap Condition continues to exist, all Excess Cash Flow (except as otherwise expressly provided below) shall be deposited with the Indenture Trustee and held in a Sub-Account of the Central Account

(the “Cash Trap Reserve Sub-Account”) in accordance with the terms of the Cash Management Agreement and this Indenture (said funds, together with any interest thereon, the “Cash Trap Reserve”). Following the occurrence and during the continuation (which shall be based upon the financial reporting required to be delivered pursuant to Section 7.02(a)(iv)) of an Early Amortization Event or an Event of Default, the Indenture Trustee shall apply all funds deposited in the Cash Trap Reserve Sub-Account from time to time on any Payment Date to payment of the Outstanding principal on each Class of Notes on a pro rata basis within each such Class on such Payment Date (including any required Prepayment Consideration). Any such ratable repayment will be applied first to reduce the Class Principal Balance of the Class A Notes until the Class Principal Balance of the Class A Notes is reduced to zero and then to reduce the Class Principal Balance of any Notes having a later alphabetical designation than the Class A Notes, sequentially in alphabetical order, until the Class Principal Balance of each such Class of Notes is, in turn, reduced to zero. For such purposes, the Class A-1 Notes shall be deemed to have the same alphabetical designation as the Class A-2 Notes and shall be pari passu with the Class A-2 Notes. If a Cash Trap Condition ceases to exist (which shall be based upon the financial reporting required to be delivered pursuant to Section 7.02(a)(iv)) and no Event of Default has occurred and is continuing, any funds then on deposit in the Cash Trap Reserve Sub-Account shall be released to the Issuer Entity. The existence of a Cash Trap Condition or an Early Amortization Event and the calculation of DSCR shall be determined by the Servicer in its reasonable good faith determination, which may be based solely upon the Financial Statements received by the Servicer.

and, in the case of each such Holder, shall be made by wire transfer of immediately available funds to the account thereof, if such Holder shall have provided the Indenture Trustee with wiring instructions no later than five Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent Payment Dates), and otherwise shall be made by check mailed to the address of such Holder as it appears in the Note Register. The final payment on each Note shall be made in a like manner, but only upon presentation and surrender of such Note at the offices of the Note Registrar or such other location specified in the notice to Noteholders of such final payment.

Each DTC Participant shall be responsible for making such payment to the related Note Owners that it represents and to each indirect participating brokerage firm for which it acts as agent. Each such indirect participating brokerage firm shall be responsible for disbursing funds to the related Note Owners that it represents.

The Issuers shall perform their respective obligations under the Letters of Representations among the Issuers and the initial Depositary.

(e) The rights of the Noteholders to receive payments from the proceeds of the Collateral in respect of their Notes, and all rights and interests of the Noteholders in and to such payments, shall be as set forth in this Indenture. Neither the Holders of any Class of Notes nor any party hereto shall in any way be responsible or liable to the Holders of any other Class of Notes in respect of amounts previously paid on the Notes in accordance with this Indenture.

(f) Except as otherwise provided herein, whenever the Indenture Trustee receives written notice that the final payment with respect to any Class of any Series of Notes shall be made on the next Payment Date, the Indenture Trustee shall, as promptly as possible thereafter, mail to each Holder of such Class of such Series of Notes of record on such date and the Servicer a notice to the effect that:

(i) the Indenture Trustee expects that the final payment with respect to such Class of such Series of Notes shall be made on such Payment Date but only upon presentation and surrender of such Notes at the office of the Note Registrar or at such other location therein specified, and

(ii) no interest shall accrue on such Notes from and after the end of the Interest Accrual Period for such Payment Date.

Any funds not paid to any Holder or Holders of Notes of such Class on such Payment Date because of the failure of such Holder or Holders to tender their Notes shall, on such date, be set aside and credited to, and shall be held uninvested in trust for, the account or accounts of the appropriate non-tendering Holder or Holders. If any Notes

as to which notice has been given pursuant to this Section 5.01(f) shall not have been surrendered for cancellation within six months after the time specified in such notice, the Indenture Trustee shall mail a second notice to the remaining non-tendering Noteholders to surrender their Notes for cancellation in order to receive the final payment with respect thereto. If within one year after the second notice all such Notes shall not have been surrendered for cancellation, then the Indenture Trustee, directly or through an agent, shall take such steps to contact the remaining non-tendering Noteholders concerning the surrender of their Notes as it shall deem appropriate. The costs and expenses of holding such funds in trust and of contacting such Noteholders following the first anniversary of the delivery of such second notice to the non-tendering Noteholders shall be paid out of such funds. No interest shall accrue or be payable to any former Holder on any amount held in trust pursuant to this paragraph. If any Notes as to which notice has been given pursuant to this Section 5.01(f), shall not have been surrendered for cancellation by the second anniversary of the delivery of the second notice, then, subject to applicable escheat laws, the Indenture Trustee shall distribute to the Issuer Entity all unclaimed funds.

(g) Notwithstanding any other provision of this Indenture, the Indenture Trustee shall comply with all Federal withholding requirements respecting payments to Noteholders of interest or original issue discount that the Indenture Trustee reasonably believes are applicable under the Code. The consent of Noteholders shall not be required for such withholding. If the Indenture Trustee does withhold any amount from payments or advances of interest or original issue discount to any Noteholder pursuant to Federal withholding requirements, the Indenture Trustee shall indicate the amount withheld to such Noteholder. Any amount so withheld by the Indenture Trustee shall be treated as a payment made to the Noteholders for all purposes of this Indenture.

(g) The Permitted Encumbrances, in the aggregate, do not materially interfere with the benefits of the security intended to be provided by this Indenture, materially and adversely affect the value of any of the Collateral taken as a whole, impair the use or operations of the Tower Sites or impair the Issuers’ ability to pay their respective obligations in a timely manner.

SECTION 6.06. Zoning; Compliance with Laws. The Tower Sites and the use thereof comply with all applicable zoning, subdivision and land use laws, regulations and ordinances, all applicable health, fire, building codes, parking laws and all other laws, statutes, codes, ordinances, rules and regulations applicable to the Tower Sites, or any of them, including without limitation, the Americans with Disabilities Act, except to the extent failure to so comply would not, in the aggregate, be reasonably likely to have a Material Adverse Effect. All permits, licenses and certificates for the lawful use, occupancy and operation of each component of each of the Tower Sites given as Collateral hereunder in the manner in which it is currently being used, occupied and operated have been obtained and are current and in full force and effect, except to the extent failure to obtain any such permits, licenses or certificates would not, in the aggregate, be reasonably likely to have a Material Adverse Effect. To the Issuers’ Knowledge, (i) no legal proceedings are pending or threatened with respect to the zoning of any Tower Site and (ii) neither the zoning nor any other right to construct, use or operate any Tower Site is in any way dependent upon or related to any real estate other than such Tower Site, except to the extent same would not, in the aggregate, be reasonably likely to have a Material Adverse Effect.

To the Issuers’ Knowledge, each of the Leases is valid and binding on the parties thereto in accordance with its terms.

(c) Management Agreement.

The Issuers have no knowledge of any latent or patent structural or other material defect or deficiency in the Tower Sites, and all necessary utilities are fully connected to the Improvements and are fully operational, are sufficient to meet the reasonable needs of each of the Tower Sites as now used or presently contemplated to be used, and no other utility facilities or repairs are necessary to meet the reasonable needs of each of the Tower Sites as now used or presently contemplated except in each case where such failure, in the aggregate, is not reasonably likely to have a Material Adverse Effect. To the Issuers’ Knowledge, none of the Improvements create encroachments over, across or upon the Tower Sites’ boundary lines, rights of way or easements, and no building or other improvements on adjoining land create such an encroachment, which could reasonably be expected to have a Material Adverse Effect. Access has been insured for all Ground Leased Tower Sites and the Issuers have access to each of the Owned Tower Sites except to the extent that failure to have such access would not be reasonably likely to have a Material Adverse Effect.

SECTION 6.09. Litigation; Adverse Facts. Except as set forth on Schedule 6.09, there are no judgments outstanding against any Issuer Party, or affecting any of the Tower Sites or any property of any Issuer Party, nor to the Issuer Party’s Knowledge is there any action, charge, claim, demand, suit, proceeding, petition, governmental investigation or arbitration now pending or threatened against any Issuer Party or any of the Tower Sites that could reasonably be expected to result in a Material Adverse Effect.

SECTION 6.10. Taxes. All material Federal, state and local tax returns and reports of the Issuers required to be filed have been timely filed (or each such Person has timely filed for an extension and the applicable extension has not expired), and all

taxes, assessments, fees and other governmental charges (including any payments in lieu of taxes) upon such Persons and upon its properties, assets, income and franchises which are due and payable have been paid except to the extent same are being contested in accordance with Section 7.04(b) and except to the extent the effect of which is not reasonably likely to have a Material Adverse Effect.

SECTION 6.11. Adverse Contracts. Except for the Transaction Documents, the Issuers are not parties to or bound by, nor is any property of such Person subject to or bound by, any contract or other agreement which restricts such Person’s ability to conduct its business in the ordinary course as currently conducted that, either individually or in the aggregate, has a Material Adverse Effect or could reasonably be expected to have a Material Adverse Effect.

SECTION 6.12. Performance of Agreements. To the Issuers’ Knowledge, no Issuer is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any Contractual Obligation of any such Issuer which could reasonably be expected to have a Material Adverse Effect, and no condition exists that, with the giving of notice or the lapse of time or both, would constitute such a default which could reasonably be expected to have a Material Adverse Effect.

SECTION 6.13. Governmental Regulation. No Issuer Party is subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act or the Investment Company Act of 1940 or to any Federal or state statute or regulation limiting its ability to incur indebtedness for borrowed money.

SECTION 6.14. Employee Benefit Plans. Except as set forth on Schedule 6.14, no Issuer Party maintains or contributes to, or has any obligation (including a Contingent Obligation) under, any Employee Benefit Plans.

SECTION 6.15. Broker’s Fees. No broker’s or finder’s fee, commission or similar compensation shall be payable by or pursuant to any contract or other obligation of the Issuers with respect to the issuance of the Notes or any of the other transactions contemplated hereby or by any of the Transaction Documents.

SECTION 6.16. Solvency. The Issuer Parties (a) have not entered into any Transaction Document with the actual intent to hinder, delay, or defraud any creditor and (b) have received reasonably equivalent value in exchange for their obligations under the Transaction Documents. After giving effect to the issuance of the Notes, the fair saleable value of the each Issuer Party’s assets exceed and shall, immediately following the issuance of the Notes, exceed such Issuer’s total liabilities, including, without limitation, subordinated, unliquidated, disputed and Contingent Obligations. The fair saleable value of each Issuer Party’s assets is and shall, immediately following the issuance of the Notes, be greater than such Issuer Party’s probable liabilities, including the maximum amount of its Contingent Obligations on its debts as such debts become absolute and matured. Each of the Issuer Party’s assets do not and, immediately following the issuance of the Notes shall not, constitute unreasonably small capital to

carry out its business as conducted or as proposed to be conducted. The Issuer Parties do not intend to, and do not believe that they shall, incur Indebtedness and liabilities (including Contingent Obligations and other commitments) beyond their ability to pay such Indebtedness and liabilities as they mature (taking into account the timing and amounts of cash to be received by the Issuers and the amounts to be payable on or in respect of obligations of the Issuer Parties).

No later than the date the Issuers are required to provide the reports under clauses (i) through (ix) above to the Indenture Trustee and the Servicer, either (i) the Issuers may post such reports on the website of an Issuer (or the website of the Crown International) and maintain such posting so long as any Notes remain outstanding or (ii) Crown International may file or furnish such reports on its Form 10-K, 10-Q or 8-K, as the case may be, on EDGAR.

arbitration at any time pending against or affecting the Issuers or the Tower Sites which, in each case, if adversely determined could reasonably be expected to have a Material Adverse Effect, the Issuers shall give notice thereof to the Indenture Trustee and the Servicer and, upon request from the Servicer or the Indenture Trustee, provide such other information as may be reasonably available to them to enable the Indenture Trustee and its counsel and the Servicer and its counsel to evaluate such matter.

SECTION 7.04. Payment of Impositions and Claims. (a) Except for those matters being contested pursuant to clause (b) below, the Issuers shall pay (i) all Impositions; (ii) all material claims (including claims for labor, services, materials and supplies) for sums that have become due and payable and that by law have or may become a Lien upon any of its properties or assets (hereinafter referred to as the “Claims”); and (iii) all Federal, state and local income taxes, sales taxes, excise taxes and all other taxes and assessments of the Issuers on their business, income or assets (other than de minimus taxes and assessments); in each instance before any penalty or fine is incurred with respect thereto.

(b) The Issuers shall not be required to pay, discharge or remove any Imposition or Claim relating to a Tower Site so long as the Issuers contest in good faith such Imposition, Claim or the validity, applicability or amount thereof by an appropriate negotiation, mediation, arbitration or legal proceeding which operates to prevent the collection of such amounts and the sale of the applicable Tower Site or any portion thereof, so long as: (i) no Event of Default shall have occurred and be continuing, (ii) prior to the date on which such Imposition or Claim would otherwise have become delinquent, the Issuers shall have given the Indenture Trustee and the Servicer prior written notice of their intent to contest said Imposition or Claim and shall have deposited with the Indenture Trustee (or with a court of competent jurisdiction or other appropriate body reasonably approved by the Servicer) such additional amounts as are necessary to keep on deposit at all times, an amount by way of cash (or other form reasonably satisfactory to the Servicer), equal to (after giving effect to any Reserves then held by the Indenture Trustee for the item then subject to contest) at least 125% of the total of (x) the balance of such Imposition or Claim then remaining unpaid, and (y) all interest, penalties, costs and charges accrued or accumulated thereon; (iii) no risk of sale, forfeiture or loss of any interest in the applicable Tower Site or any part thereof arises, in the Servicer’s reasonable judgment, during the pendency of such contest; (iv) such contest does not, in the Servicer’s reasonable determination, have a Material Adverse Effect; and (v) such contest is based on bona fide, material, and reasonable claims or defenses. Any such contest shall be prosecuted with due diligence, and the Issuers shall promptly pay the amount of such Imposition or Claim as finally determined, together with all interest and penalties payable in connection therewith. The Indenture Trustee (at the sole direction of the Servicer) shall have full power and authority, but no obligation, to apply any amount deposited with the Indenture Trustee to the payment of any unpaid Imposition or Claim to prevent the sale or forfeiture of the applicable Tower Site for non-payment thereof, if the Servicer reasonably believes that such sale or forfeiture is threatened.

SECTION 7.05. Maintenance of Insurance. The Issuers shall continuously maintain the following described policies of insurance, subject to commercially reasonable policy exclusions and deductibles, without cost to the Indenture Trustee or the Servicer (the “Insurance Policies”):

(i) Property insurance against loss and damage by all risks of physical loss or damage, subject to standard policy exclusions, and other risks covered by the so-called extended coverage endorsement covering the Improvements (other than building foundations and footings) and personal property on each of the Tower Sites owned by any of the Issuers, with coverage for business income loss during the period of restoration, in amounts not less than the full insurable replacement cost of all Improvements (less building foundations and footings) and personal property on the Tower Sites owned by any Issuer;

(ii) Commercial general liability insurance, including death, bodily injury and broad form property damage coverage with a combined single limit in an amount not less than $1,000,000 per occurrence and $2,000,000 in the aggregate for any policy year;

(iii) If any of the Tower Sites (other than the Managed Tower Sites) are in an area (1) prone to earthquakes, as determined by the Manager, or (2) located in whole or in part in a Federally designated “special flood hazard area”, insurance covering such risks with respect to the Improvements (other than building foundations and footings) and personal property owned by any Issuer on such Tower Site in an amount equal to 100% of the full insurable replacement cost of all Improvements (less building foundations and footings) and personal property on such Tower Site owned by any Issuer with a maximum permissible deductible of $25,000 per occurrence and $10,000,000 in the aggregate;

(iv) An umbrella excess liability policy with a limit of not less than $25,000,000 over the underlying primary commercial general liability and automobile liability coverage described in Section 7.05(ii) above;

(v) During any period of construction, repair or restoration conducted by or on behalf of any Issuer on any Tower Site, builders “all risk” insurance in an amount equal to not less than the full insurable replacement cost of the applicable construction project;

(vi) Worker’s compensation insurance in statutory amounts, if any, at all times;

(vii) Such other insurance as may from time to time be reasonably required by the Servicer and which is then customarily required by institutional lenders for securitized loans secured by similar properties similarly situated, against other insurable hazards, including, but not limited to, malicious mischief, vandalism, windstorm, due regard to be given to the size and type of the Tower Site, Improvements, fixtures and equipment and their location, construction and use. Additionally, the Issuers shall carry such insurance coverage as the Indenture Trustee or the Servicer may from time to time require if the failure to carry such insurance would result in a downgrade, qualification or withdrawal of any Class of Notes.

All Insurance Policies shall be in content (including, without limitation, endorsements or exclusions, if any) and form reasonably satisfactory to the Servicer from time to time and, to the extent permissible, shall name the Indenture Trustee and its successors and assignees as their interests may appear as an “additional loss payee” for each of the first party property policies required by this Section 7.05 and shall contain a waiver of subrogation clause reasonably acceptable to the Servicer. Indenture Trustee and its successors and assignees will be added as an “additional insured” on all liability insurance policies required by this Section 7.05. All Insurance Policies required by this Section 7.05 shall provide that the coverage shall not be modified without 30 days’ advance written notice to the Indenture Trustee and the Servicer, and under all first party property claims the Indenture Trustee’s interest in the property will have priority in payments made by the insurer. The Issuers may obtain any insurance required by this Section through blanket policies; provided, however, that such blanket policies shall afford all the protections to the Indenture Trustee as are required under this Section 7.05.

The Issuers shall on the Closing Date and thereafter, within 120 days following the end of each calendar year, deliver to the Indenture Trustee and the Servicer valid evidence of property insurance in the form of ACORD form 28, Evidence of Insurance, or a comparable certificate of insurance affirming: the issuance of the policies of insurance required by this Indenture, that the insurance coverage meets all of the requirements set forth in this Indenture and that the required policies are in full force and effect. An insurance company shall (a) be licensed or authorized to issue insurance in the State where the applicable Tower Site is located and (b) have a claims paying ability rating by the Rating Agencies of “A” (or its equivalent). Notwithstanding the foregoing, a carrier which does not meet the foregoing ratings requirement shall nevertheless be deemed acceptable hereunder provided that such carrier is reasonably acceptable to the Servicer and the Issuers shall obtain and deliver to the Servicer a Rating Agency Confirmation with respect to such carrier from each of the Rating Agencies. If any insurance coverage required under this Section 7.05 is maintained by a syndicate of insurers, the preceding ratings requirements shall be deemed satisfied (without any required Rating Agency Confirmation) as long as at least 75% of the coverage (if there are four or fewer members of the syndicate) or at least 60% of the coverage (if there are five or more members of the syndicate) is maintained with carriers meeting the claims-paying ability ratings requirements set forth above and all carriers in such syndicate have a claims-paying ability rating by Moody’s of not less than “Baa2” (to the extent rated by Moody’s) and by Fitch of not less than “BBB” (to the extent rated by Fitch). The Issuers shall furnish to the Indenture Trustee and the Servicer receipts for the payment of premiums on such Insurance Policies or other evidence of such payment reasonably satisfactory to the Servicer in the event that such premiums have not been paid by the Manager or the Indenture Trustee pursuant to this Indenture. The requirements of this Section 7.05 shall apply to any separate policies of insurance taken out by the Issuers concurrent in form or contributing in the event of loss with the Insurance Policies. First party property losses shall be payable to the Indenture Trustee notwithstanding (1) any act, failure to act or negligence of the Issuers or their agents or employees, the Indenture Trustee or any other insured party which might, absent such agreement, result in a forfeiture of all or part of such insurance payment, other than the wilful misconduct of the Indenture Trustee knowingly in violation of the conditions of such policy, (2) the occupation or use of the Tower Sites or any part thereof for purposes more hazardous than permitted by the terms of such policy, (3) any foreclosure or other action or proceeding taken pursuant to this Indenture or (4) any change in title to or ownership of the Tower Sites or any part thereof following the date on which such loss occurred.

For purposes of determining whether the required insurance coverage is being maintained hereunder, each of the Indenture Trustee and Servicer shall be entitled to rely solely on a certification thereof (including in the form of ACORD form 28, Evidence of Insurance) furnished to it by the Issuer Entity or the Manager, without any obligation to investigate the accuracy or completeness of any information set forth therein, and shall have no liability with respect thereto.

SECTION 7.06. Operation and Maintenance of the Tower Sites; Casualty; Condemnation. (a) The Issuers shall maintain or cause to be maintained in good repair, working order and condition all material property necessary for use in the business of

each Issuer, including the applicable Tower Site, and shall make or cause to be made all appropriate repairs, renewals and replacements thereof. All work required or permitted under this Indenture shall be performed in a workmanlike manner and in compliance with all applicable laws.

(b) (i) In the event of casualty or loss at any of the Tower Sites, the Issuers shall give prompt written notice, and in any event within three Business Days, of any such casualty or loss exceeding $250,000, or which is not covered by insurance (subject to applicable deductibles), to the insurance carrier (if applicable), to the Indenture Trustee and the Servicer and to promptly commence and diligently prosecute to completion, in accordance with the terms hereof, the repair and restoration of the Tower Site at least substantially to the Pre-Existing Condition (a “Restoration”). The Issuers hereby authorize and empower the Servicer as attorney-in-fact for the Issuers (jointly with the Issuers unless an Event of Default has occurred and is continuing), or any of them, with respect to Insurance Proceeds in excess of $1,000,000 to make proof of loss, to adjust and compromise any claim under Insurance Policies, to appear in and prosecute any action arising from such Insurance Policies, to collect and receive Insurance Proceeds (to be held in the Loss Proceeds Reserve Sub-Account pending the Issuers’ determination with respect to Restoration of the affected Tower Site as set forth in Section 7.06(c)), and to deduct therefrom the Indenture Trustee’s and the Servicer’s expenses incurred in the collection of such proceeds; provided, however, that nothing contained in this Section shall require the Indenture Trustee or the Servicer to incur any expense or take any action hereunder. The Issuer Entity further authorizes the Indenture Trustee, at the Servicer’s option and direction, with respect to Insurance Proceeds in excess of $1,000,000 (a) to hold the balance of such proceeds to be made available to the Issuers for the cost of Restoration of any of the Tower Sites or (b) subject to Section 7.06(c), to apply such Insurance Proceeds to payment of the Obligations whether or not then due; provided, however, that any such prepayments first shall be allocated or distributed pursuant to Section 5.01(a), items first through seventh, and then be applied to reduce the Class Principal Balance of the Class A Notes on a pro rata basis until the Class Principal Balance of the Class A Notes is reduced to zero, and then to reduce the Class Principal Balance of any Notes having a later alphabetical designation than the Class A Notes, sequentially in alphabetical order, until the Class Principal Balance of each such Class of Notes is, in turn, reduced to zero. Application of any Insurance Proceeds to payment of the Obligations pursuant to the foregoing sentence shall be made with the required Prepayment Consideration.

(ii) The Issuers shall promptly, and in any event within three Business Days, give the Indenture Trustee written notice of any known actual or threatened commencement of any condemnation or eminent domain proceeding affecting the Tower Sites or any portion thereof and, upon the request of the Indenture Trustee or the Servicer, shall deliver to the Indenture Trustee and the Servicer copies of any and all papers served in connection with such proceedings. The Servicer is hereby irrevocably appointed as the attorney-in-fact for the Issuers (jointly with the Issuers unless an Event of Default has occurred and is continuing), or any of

them, with respect to Condemnation Proceeds in excess of $1,000,000 to collect, receive and retain any Condemnation Proceeds (to be held in the Loss Proceeds Reserve Sub-Account pending the Issuers’ determination with respect to Restoration of the affected Tower Site as set forth in Section 7.06(c)) and to make any compromise or settlement in connection with such proceeding. In accordance with the terms hereof, the Issuers shall cause the Condemnation Proceeds in excess of $1,000,000 which are payable to the Issuers, to be paid directly to the Indenture Trustee. If the applicable Tower Site is sold following an Event of Default, through foreclosure or otherwise, prior to the receipt by the Indenture Trustee of Condemnation Proceeds, the Indenture Trustee shall have the right to receive said Condemnation Proceeds, or a portion thereof, sufficient to pay the Obligations. Notwithstanding the foregoing, the Issuers may prosecute any Condemnation Proceeding and settle or compromise and collect Condemnation Proceeds of not more than $1,000,000; provided that: (a) no Event of Default shall have occurred and be continuing, (b) in Servicer’s reasonable good faith judgment, such condemnation or taking does not and will not materially restrict access to the Tower Sites or otherwise have a Material Adverse Effect and the Tower Sites remaining after such condemnation or taking are capable of being restored to an economically viable whole of substantially the same type which existed prior to the condemnation or taking or in substantial compliance with all applicable laws, (c) the Issuers apply the Condemnation Proceeds to any reconstruction or repair of the Tower Site necessary or desirable as a result of such condemnation or taking, and (d) the Issuers promptly commence and diligently prosecute such reconstruction or repair to completion in accordance with all applicable laws. Except as provided for in the previous sentence, the Issuers authorize the Servicer and the Indenture Trustee to apply such Condemnation Proceeds, after the deduction of the Indenture Trustee’s and the Servicer’s reasonable expenses incurred in the collection of such Condemnation Proceeds, at the Servicer’s option and direction, (i) to restoration or repair of the Tower Sites or (ii) to payment on the Notes, whether or not then due (provided that the Indenture Trustee (at the direction of the Servicer) shall not exercise the option in this clause (ii) to apply such Condemnation Proceeds to payment of the Obligations if each of the conditions (as applicable) to the release of Loss Proceeds for restoration or repair of the Tower Sites under Section 7.06(c) below have been satisfied with respect to such condemnation awards or damages), with the balance, if any, to the Issuers; provided, however, that any such prepayments first shall be allocated or distributed pursuant to Section 5.01(a), items first through seventh, and then be applied to reduce the Class Principal Balance of the Class A Notes on a pro rata basis until the Class Principal Balance of the Class A Notes is reduced to zero, and then to reduce the Class Principal Balance of any Notes having a later alphabetical designation than the Class A Notes, sequentially in alphabetical order, until the Class Principal Balance of each such Class of Notes is, in turn, reduced to zero. Application of any Condemnation Proceeds to payment of the Obligations pursuant to the foregoing sentence shall be made with the required Prepayment Consideration.

(c) The Servicer will not direct the Indenture Trustee to exercise its option to apply Loss Proceeds to payment of the Obligations if all of the following conditions are met: (i) no Event of Default then exists; (ii) the Servicer reasonably determines that there shall be sufficient funds to complete the Restoration of the Tower Site to at least substantially to the condition it was in immediately prior to such casualty (excluding replacement of obsolete Collateral which is not required in connection with operating the applicable Tower Site) and in compliance with applicable laws (the “Pre-Existing Condition”); (iii) the Servicer reasonably determines that the Net Operating Income of the Tower Sites (including rental income or business interruption insurance) will be sufficient to pay principal and interest on the Notes, all Operating Expenses, and payments for Reserves; and (iv) the Servicer determines that the Restoration of the affected Tower Site to the Pre-Existing Condition will be completed not later than six months prior to the latest Applicable Maturity Date. If the Servicer elects to direct the Indenture Trustee to apply Loss Proceeds to payment of the Obligations, such application shall be made on the Payment Date immediately following such election in accordance with the terms of the Indenture. Notwithstanding the foregoing to the contrary, the Issuers may, in their reasonable discretion, and within 30 days of receipt of such Loss Proceeds, elect not to restore or replace a Tower Site, in which event all such Loss Proceeds held in the Loss Proceeds Reserve Sub-Account with respect to such Tower Site first shall be allocated or distributed pursuant to Section 5.01(a), items first through seventh, and then be applied to reduce the Class Principal Balance of the Class A Notes on a pro rata basis until the Class Principal Balance of the Class A Notes is reduced to zero, and then to reduce the Class Principal Balance of any Notes having a later alphabetical designation than the Class A Notes, sequentially in alphabetical order, until the Class Principal Balance of each such Class of Notes is, in turn, reduced to zero. Any such prepayment shall be made on the Payment Date immediately following such election and shall include the applicable Prepayment Consideration.

(d) The Indenture Trustee shall not be obligated to disburse Loss Proceeds more frequently than once every calendar month. If Loss Proceeds are applied to the payment of the Obligations, such application of Loss Proceeds to principal shall be with the applicable Prepayment Consideration and shall not extend or postpone the due dates of the monthly payments due under the Note or otherwise under the Transaction Documents, or change the amounts of such payments. Any amount of Loss Proceeds remaining in the Indenture Trustee’s possession after full and final payment and discharge of all Obligations shall be refunded to, or as directed by, the Issuers or otherwise paid in accordance with applicable law. If a Tower Site is sold at foreclosure or if the Indenture Trustee acquires title to a Tower Site, the Indenture Trustee shall have all of the right, title and interest of the applicable Issuer in and to any Loss Proceeds and unearned premiums on Insurance Policies.

(e) In no event shall the Indenture Trustee be obligated to make disbursements of Loss Proceeds in excess of an amount equal to the costs actually incurred from time to time for work in place as part of the Restoration, as certified

by the Issuers, less a retainage equal to the greater of (x) the actual retainage required pursuant to the permitted contract, or (y) 10% of such costs incurred until the Restoration has been completed. The retainage shall in no event be less than the amount actually held back by the Issuers from contractors, subcontractors and materialmen engaged in the Restoration. The retainage shall not be released until the Servicer is reasonably satisfied that the Restoration has been completed in accordance with the provisions of this Section 7.06 and that all approvals necessary for the re-occupancy and use of the Tower Site have been obtained from all appropriate Governmental Authorities, and the Servicer receives final Lien waivers and such other evidence reasonably satisfactory to the Servicer that the costs of the Restoration have been paid in full or shall be paid in full out of the retainage.

SECTION 7.07. Inspection; Investigation. Each Issuer shall permit any authorized representatives designated by the Indenture Trustee or the Servicer to visit and inspect during normal business hours its Tower Sites and its business, including its financial and accounting records, and to make copies and take extracts therefrom and to discuss its affairs, finances and business with its officers and independent public accountants (with such Issuer’s representative(s) present), at such reasonable times during normal business hours and as often as may be reasonably requested, provided that same is conducted in such a manner as to not unreasonably interfere with the Issuers’ business. In addition, such authorized representatives of the Indenture Trustee and Servicer shall also have the right to conduct site investigations of the Tower Sites with respect to environmental matters; provided, however, that no subsurface investigations or other investigations that would reasonably be deemed to be intrusive shall be conducted without the prior written consent of the Issuer, such consent not to be unreasonably withheld. Unless an Event of Default has occurred and is continuing, the Indenture Trustee and Servicer shall provide advance written notice of at least three Business Days prior to visiting or inspecting any Tower Site or such Issuer’s offices.

SECTION 7.08. Compliance with Laws and Obligations. (a) The Issuers shall (A) comply with the requirements of all present and future applicable laws, rules, regulations and orders of any governmental authority in all jurisdictions in which it is now doing business or may hereafter be doing business, other than those laws, rules, regulations and orders the noncompliance with which collectively could not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect, (B) maintain all licenses and permits now held or hereafter acquired by any Issuer, the loss, suspension, or revocation of which, or failure to renew, in the aggregate could have a Material Adverse Effect and (C) perform, observe, comply and fulfill all of its material obligations, covenants and conditions contained in any Contractual Obligation unless contested by the Issuers in good faith in a manner substantially similar to Section 7.04.

(b) Except as otherwise expressly set forth in the Transaction Documents, the Issuer Parties shall not waive, amend, modify, supplement or terminate any such Transaction Documents or any provision thereof without the consent of the Noteholders representing more than 50% of the aggregate Outstanding Class Principal Balance of all Classes of Notes.

SECTION 7.09. Further Assurances. The Issuers shall, from time to time, execute and/or deliver such documents, instruments, agreements, financing statements, and perform such acts as the Indenture Trustee and/or the Servicer at any time may reasonably request to evidence, preserve and/or protect the Assets and Collateral at any time securing or intended to secure the Obligations and/or to better and more effectively carry out the purposes of this Indenture and the other Transaction Documents.

SECTION 7.10. Performance of Agreements. Each Issuer shall duly and punctually perform, observe and comply in all material respects with all of the terms, provisions, conditions, covenants and agreements on its part to be performed, observed and complied with (i) hereunder and under the other Transaction Documents to which it is a party, (ii) under all Material Agreements and Leases and (iii) all other agreements entered into or assumed by such Person in connection with the Tower Sites, and shall not suffer or permit any material default or event of default (giving effect to any applicable notice requirements and cure periods) to exist under any of the foregoing except where the failure to perform, observe or comply with any agreement referred to in this clause (iii) would not reasonably be expected to have a Material Adverse Effect. Notwithstanding the foregoing to the contrary, the Issuers shall be permitted to terminate any Tower Site Management Agreement which the Issuers reasonably deem necessary in accordance with prudent business practices, provided that (i) the Issuers provide written notice to the Indenture Trustee and the Servicer of such determination not later than thirty (30) days prior to such termination, (ii) together with such notice the Issuers provide a certificate reasonably acceptable to the Servicer certifying that (on a pro forma basis) for such termination the projected DSCR for the 12-month period following such termination will be equal to or greater than the projected DSCR during such 12-month period assuming such termination did not occur (for purposes of calculating the DSCR during such 12-month period, the Issuer may give pro forma effect to the prospective impact on any of the items included in the calculation of the DSCR, including the projected costs associated with compliance with applicable environmental laws, increases in property taxes, costs associated with the renewal or modification of such Tower Site Management Agreement, and such other factors related to such particular Tower Site Management Agreement which could reasonably be expected to impact the DSCR) and (iii) if (1) the aggregate Allocated Note Amount with respect to (x) each such Tower Site for which termination has occurred under this Section 7.10, Section 7.24(a), and Section 7.25(a), and (y) the Tower Site for which a termination is proposed, is greater than 5% of the aggregate Initial Class Principal Balance of all Classes of Notes, or (2) at least 78% of the Operating Revenues of the Tower Sites that remain following a proposed termination do not consist of wireless voice or data revenues, the Issuers have provided prior written notice to each Rating Agency.

SECTION 7.11. Leases. Any Rents which constitute Advance Rents Reserve Deposits shall be deposited into the Advance Rents Reserve Sub-Account to be applied in accordance with the Cash Management Agreement. The Issuers shall, at the Indenture Trustee’s or the Servicer’s request, furnish the Indenture Trustee or Servicer, as applicable, with executed copies of all Material Leases hereafter made. Each new Lease other than (x) the addition of new sites pursuant to existing master Leases, or (y) Governmental Leases shall specifically provide that such Lease (i) is subordinate to the

Indenture, provided that the Indenture Trustee agrees not to disturb the applicable Tenant’s possession for so long as Tenant is not in default under the terms of the applicable Lease (as evidenced by an agreement to that effect (each such agreement, a “Lease Estoppel”)); (ii) that the Tenant attorns to the Indenture Trustee; (iii) that the attornment of the Tenant shall not be terminated by foreclosure; and (iv) that in no event shall the Indenture Trustee, as successor landlord or as a direct or indirect successor owner of an Issuer, be liable to the Tenant for any act or omission of any prior landlord or for any liability or obligation of any prior landlord occurring prior to the date that the Indenture Trustee or any subsequent owner acquires title (whether directly or indirectly through ownership of an Issuer) to the Tower Site. On the Closing Date and at such other times as shall be required by applicable law (including upon replacement of the Manager), the Indenture Trustee shall execute a power of attorney enabling Manager (on behalf of the Indenture Trustee) to execute Lease Estoppels in a form reasonably satisfactory to the Indenture Trustee and the Servicer (with the appropriate information completed therein) without any material changes being made to the form.

SECTION 7.12. Management Agreement. (a) The Issuers shall cause the Manager to manage the Tower Sites in accordance with the Management Agreement. The Issuers shall (i) perform and observe all of the material terms, covenants and conditions of the Management Agreement on the part of each Issuer to be performed and observed and (ii) promptly notify the Indenture Trustee and the Servicer of any notice to any of the Issuers of any material default under the Management Agreement of which it is aware. If any of the Issuers shall default in the performance or observance of any material term, covenant or condition of the Management Agreement on the part of the Issuers to be performed or observed, then, without limiting the Indenture Trustee’s other rights or remedies under this Indenture or the other Transaction Documents, and without waiving or releasing the Issuers from any of their obligations hereunder or under the Management Agreement, the Issuers grant the Indenture Trustee or the Servicer on its behalf the right, upon prior written notice to the Issuers, to pay any sums and to perform any act as may be reasonably appropriate to cause such material conditions of the Management Agreement on the part of the Issuers to be performed or observed; provided, however, that neither the Indenture Trustee nor the Servicer shall be under any obligation to pay such sums or perform such acts.

(b) The Issuers shall not surrender, terminate, cancel, or modify (other than non-material changes), the Management Agreement, or enter into any other management agreement with any new Manager, or consent to the assignment by the Manager of its interest under the Management Agreement, in each case without delivery of prior written notice to each Rating Agency and written consent of the Servicer; provided, however, that written consent of the Servicer is not required to the extent an Acceptable Manager replaces the existing Manager under the existing Management Agreement (other than as modified by any non-material change). If the Servicer consents to the appointment of a new Manager, or if an Acceptable Manager becomes the Manager, such new Manager, or the Acceptable Manager, as the case may be, and the Issuers shall, or with respect to an Acceptable Manager, prior to commencement of its duties as Manager, execute a subordination of management agreement in substantially the form previously delivered by the Manager as of the Closing Date.

(d) The Indenture Trustee and the Servicer are each permitted to utilize and in good faith rely upon the advice of the Manager (or to utilize, at its own expense (except to the extent that a particular expense is expressly provided herein to be an Advance or an Additional Issuer Expense) other agents or attorneys), in performing certain of its obligations under this Indenture and the other Transaction Documents, including, without limitation, Tower Site management, operation, and maintenance; Tower Site dispositions, releases, terminations, additions, and substitutions; application of funds pursuant to Article V of this Indenture; and confirmation of compliance by the Issuer Parties with the provisions hereunder and under the other Transaction Documents; and neither the Indenture Trustee nor the Servicer shall have any liability with respect to utilizing and relying upon the Manager as described above.

The Issuer Entity shall give prompt written notice to the Indenture Trustee of the location, and any change in the location, of such office, agency or address; provided, however, that if the Issuer Entity does not furnish the Indenture Trustee with an address in The City of New York where Notes may be presented or surrendered for payment, such presentations, surrenders, notices, and demands may be made or served at the Corporate Trust Office, and the Issuer Entity hereby appoints the Indenture Trustee to receive all such presentations, surrenders, notices, and demands on behalf of the Issuers. The Issuer Entity hereby appoints the Corporate Trust Office as their agency for such purposes.

(b) The Issuer Entity may also from time to time designate one or more other offices or agencies where Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations.

Compliance by the Indenture Trustee with the requirements of this Section shall be for informational purposes only and shall not be deemed to be a waiver of any rights or remedies of the Indenture Trustee hereunder or under any other Transaction Document.

SECTION 7.16. Indebtedness. The Issuers shall not directly or indirectly create, incur, assume, guaranty, or otherwise become or remain directly or indirectly liable with respect to any Indebtedness except for the following (collectively, “Permitted Indebtedness”):

SECTION 7.20. Transactions with Related Persons. The Issuers shall not directly or indirectly enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property or the rendering of any service) with any Related Person of any of the Issuers or with any director, officer or employee of any Issuer, except transactions pursuant to the reasonable requirements of the business of the Issuers and upon fair and reasonable terms that are no less favorable to any of the Issuers than would be obtained in a comparable arm’s length transaction with a Person that is not a Related Person of any Issuer. The Issuers shall not make any payment or permit any payment to be made on behalf of the Issuers to any Related Person of any of the Issuers when or as to any time when any Event of Default shall exist except as may be permitted by the Indenture Trustee (solely at the discretion of the Servicer) pursuant to the terms of the Cash Management Agreement and this Indenture. Notwithstanding the foregoing, transfers of Tower Sites among the Issuers shall be permitted provided that appropriate amendments, if any, to the Transaction Documents are approved by and delivered to the Indenture Trustee and the Servicer in connection with such transfers as are necessary to continue the Indenture Trustee’s security interest in the Collateral.

The Issuer shall not file a

petition for, consent to the filing of a petition for, or aid, solicit, support, or otherwise act, cooperate or collude to cause the filing of a petition for an Involuntary Issuer Bankruptcy.

SECTION 7.22. ERISA. (a) No ERISA Plans. The Issuers shall not, and shall not permit the Guarantor to, establish any Employee Benefit Plan or Multiemployer Plan, or commence making contributions to (or become obligated to make contributions to) any Employee Benefit Plan or Multiemployer Plan.

(b) Compliance with ERISA. The Issuers shall not, and shall not permit the Guarantor to: (i) engage in any non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code; or (ii) except as may be necessary to comply with applicable laws, establish or amend (or have any liability, directly or indirectly, with respect to) any Employee Benefit Plan which establishment or amendment could result in liability to the Issuers, the Guarantor or any ERISA Affiliate or increase the benefits obligation of the Issuers or the Guarantor; provided that if the Issuers are in default of this covenant under subsection (i), the Issuers shall be deemed not the be in default if such default results solely because (x) any portion of the Notes have been, or shall be, funded with plan assets of any employee benefit plan that is subject to Title I of ERISA or any plan that is covered by Section 4975 of the Code and (y) notwithstanding the required representations and covenants to the contrary, the purchase or holding of such portion of the Notes by such employee benefit plan or plan constitutes a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.

(c) No Plan Assets. The Issuers shall not, and shall not permit the Guarantor to, at any time during the term of this Indenture become (1) an employee benefit plan defined in Section 3(3) of ERISA which is subject to ERISA, (2) a plan as defined in Section 4975(e)(1) of the Code which is subject to Section 4975 of the Code, (3) a “governmental plan” within the meaning of Section 3(32) of ERISA or (4) an entity any of whose underlying assets constitute (or be deemed to constitute) “plan assets” of any such employee benefit plan, plan or governmental plan for purposes of Title I of ERISA, Section 4975 of the Code or any state statutes applicable to the Issuers or the Guarantor regulating investments of governmental plans.

SECTION 7.23. Money for Payments to be Held in Trust. (a) The Paying Agent is hereby authorized to pay the principal of and interest on any Notes (as well as any other Obligation hereunder and under any other Transaction Document) on behalf of the Issuers and shall have an office or agency in The City of New York where Notes may be presented or surrendered for payment and where notices, designations or requests in respect for payments with respect to the Notes and any other Obligations due hereunder and under any other Transaction Document may be served. The Issuers hereby appoint the Indenture Trustee as the initial Paying Agent for amounts due on the Notes of each Series and the other Obligations.

(b) On each Payment Date (or such other dates as may be required or permitted hereunder) the Paying Agent shall cause all payments of amounts due and payable with respect to any Notes and other Obligations that are to be made from amounts withdrawn from the Central Account to be made on behalf of the Issuers by the Paying Agent, and no amounts so withdrawn from the Central Account for payments of the Notes and other Obligations shall be paid over to the Issuers.

(c) With respect to each Class of any Series, any Paying Agent other than the initial Paying Agent shall execute and deliver to the Indenture Trustee an instrument in which such Paying Agent shall agree with the Indenture Trustee (and if the Indenture Trustee acts as Paying Agent, it hereby so agrees) that such Paying Agent shall:

(i) hold all sums held by it for the payment of amounts due with respect to the Notes of such Class of such Series and all other Obligations in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in this Indenture and pay such sums to such Persons as provided in this Indenture;

(iv) immediately resign as a Paying Agent and forthwith pay to the Indenture Trustee all sums held by it in trust for the payment of the Notes of such Class of such Series and all other Obligations if at any time it ceases to meet the eligibility standards required to be met by a Paying Agent at the time of its appointment, in which case the Indenture Trustee shall reasonably promptly appoint a successor Paying Agent.

(d) Subject to applicable laws with respect to escheatment of funds, any money held by the Indenture Trustee or any Paying Agent in trust for the payment of any amount due with respect to any Note and remaining unclaimed for two years after such amount has become due and payable shall be discharged from such trust and be paid to the Issuer Entity on an Issuer Entity Request; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuers for payment thereof (but only to the extent of the amounts so paid to the Issuer Entity), and all liability of the Indenture Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that the Indenture Trustee or such Paying Agent, before being required to make any such repayment shall at the expense and direction of the Issuer Entity cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer Entity. The Indenture Trustee shall also adopt and employ, at the expense and direction of the Issuer Entity, any other reasonable means of notification of such repayment (including, but not limited to, mailing notice of such repayment to Holders whose right to or interest in monies due and payable but not claimed is determinable from the records of the Indenture Trustee or of any Paying Agent, at the last address of record for each such Holder).

SECTION 7.24. Ground Leases. (a) Modification. Except as provided in this Section 7.24, the Issuers shall not modify or amend any material substantive or economic terms of, or, subject to the terms hereof, terminate or surrender any Ground Lease, in each case without the prior written consent of the Servicer, which consent shall not be unreasonably withheld, conditioned or delayed. Any such attempted or purported material modification, amendment, or any surrender or termination of any Ground Lease without the Servicer’s prior written consent shall be null and void and of no force or effect. Notwithstanding the foregoing to the contrary, the Issuers may, without the Servicer’s consent:

(i) extend the terms of the Ground Leases on commercially reasonable substantive and economic terms;

(ii) terminate any Ground Lease which the Issuers reasonably deem necessary in accordance with prudent business practices; provided that (A) the Issuers provide written notice to the Indenture Trustee and the Servicer of such determination not later than 30 days prior to such termination, (B) together with such notice the Issuers provide a certificate reasonably acceptable to the Servicer certifying that (on a pro forma basis) for such termination the projected DSCR for the 12-month period following such termination will be equal to or greater than the projected DSCR during such 12-month period assuming such termination did not occur (for purposes of calculating the DSCR during such 12-month period, the Issuer may give pro forma effect to the prospective impact on any of the items included in the calculation of the DSCR, including the projected costs associated with compliance with applicable environmental laws, increases in property taxes, costs associated with the renewal or modification of such Ground Lease, and such

other factors related to such particular Ground Lease which could reasonably be expected to impact the DSCR) and (C) if (1) the aggregate Allocated Note Amount of (x) each such Tower Site for which a termination has occurred under this Section 7.24(a), Section 7.10, and Section 7.25(a) plus (y) the Tower Site for which a termination is proposed is greater than 5% of the aggregate Initial Class Principal Balance of all Classes of Notes, or (2) at least 78% of the Operating Revenues of the Tower Sites that remain following a proposed termination do not consist of wireless voice or data revenues, the Issuers shall have provided prior written notice to each Rating Agency; and

(iii) provided no Event of Default shall have occurred and is then continuing, increase the area of real property covered by a Ground Lease, and in connection therewith amend and restate the existing Ground Lease or replace the existing Ground Lease (either, an “Amended Ground Lease”), to include such additional real property, provided that such Ground Lease is on commercially reasonable substantive (including, by way of either an estoppel or as provided by the terms of the Amended Ground Lease, such lender protections as were available to the Indenture Trustee in the Ground Lease (or Estoppel delivered in connection therewith) being replaced with the Amended Ground Lease) and economic terms (taking into consideration the additional real property covered by the Amended Ground Lease), and subject to the following conditions:

(A) the Indenture Trustee and the Servicer shall have received at least ten (10) day’s prior written notice of the execution of the Amended Ground Lease, together with a summary of the economic terms thereof, and, following execution and delivery of the Amended Ground Lease, the Indenture Trustee and the Servicer shall have received a copy of the Amended Ground Lease certified by the applicable Issuer as being true, accurate and complete, together with an estoppel from the applicable Ground Lessor demonstrating that the Amended Ground Lease is in full force and effect;

(B) on or prior to execution and delivery of the Amended Ground Lease, the Indenture Trustee and the Servicer shall have received a database search environmental report from a consultant reasonably acceptable to the Servicer on the real property to be included under the Amended Ground Lease, together with a Phase I or Phase II environment assessment report (if any environmental database report search reveals any condition that in the Servicer’s reasonable judgment warrants such a report) which concludes that the subject property does not contain material amounts of any Hazardous Materials (except for cleaning and other products used in connection with the routine maintenance, operation or repair of the subject property or the operation thereof as a tower property in full compliance with Environmental Laws) and is not in material violation of any Environmental Laws;

(C) the Issuers shall pay or reimburse the Indenture Trustee and the Servicer for all reasonable costs and expenses incurred by the Indenture Trustee and the Servicer (including, without limitation, reasonable attorneys fees and disbursements) in connection with such Amended Ground Lease, and all recording charges, filing fees, taxes or other expenses (including, without limitation, mortgage and intangibles taxes and documentary stamp taxes) payable in connection therewith; and

(D) if the aggregate Allocated Note Amount of all Ground Leased Tower Sites for which an Amended Ground Lease has been executed exceeds 20% of the Initial Class Principal Balance of all Classes of Notes, the Issuers shall deliver a Rating Agency Confirmation from each Rating Agency to the Indenture Trustee.

(b) Performance of Ground Leases. The Issuers shall fully perform as and when due each and all of their obligations under each Ground Lease in accordance with the terms of such Ground Lease, and shall not cause or suffer to occur any material breach or default in any of such obligations. The Issuers shall exercise any option to renew or extend any Ground Lease and if the Issuers elect not to renew a Ground Lease (which shall only be permitted if the Issuers would be entitled to terminate such Ground Lease pursuant to clause (a) above) the Issuers shall give the Servicer and the Indenture Trustee 30 days’ prior written notice of the Issuers’ intention not to renew such Ground Lease. If the Issuers fail to renew a Ground Lease which is required to be renewed pursuant to this Section 7.24(b), the Indenture Trustee and/or the Servicer shall have the right to renew such Ground Lease on behalf of the Issuers. Notwithstanding that certain of the obligations of the Issuers under this Indenture may be similar or identical to certain of the obligations of the Issuers under the Ground Leases, all of the obligations of the Issuers under this Indenture are and shall be separate from and in addition to their obligations under the Ground Leases.

(c) Notice of Default. If any of the Issuers shall have or receive any written notice that any Ground Lease Default has occurred, then the Issuers promptly shall notify the Indenture Trustee and the Servicer in writing of the same and promptly deliver to the Indenture Trustee and the Servicer a true and complete copy of each such notice. Further, the Issuers shall provide such documents and information as the Indenture Trustee and the Servicer shall reasonably request concerning the Ground Lease Default.

(d) The Indenture Trustee’s and Servicer’s Right to Cure. If any Ground Lease Default shall occur and be continuing, or if any Ground Lessor asserts that a Ground Lease Default has occurred (whether or not the Issuers question or deny such assertion), then, subject to (i) the terms and conditions of the applicable Ground Lease and applicable law, and (ii) the Issuers’ right to terminate Ground Leases in accordance with Section 7.24(a) hereof, the Servicer, upon five Business Days’ prior written notice to the Issuers, unless the Indenture Trustee or the Servicer reasonably determines that a shorter period (or no period) of notice is necessary to

protect the Indenture Trustee’s interest in the Ground Lease, may (but shall not be obligated to) take any action that Servicer deems reasonably necessary to protect the Indenture Trustee’s interest in the Ground Lease, including, without limitation, (i) performance or attempted performance of the applicable Issuer’s obligations under the applicable Ground Lease, (ii) curing or attempting to cure any actual or purported Ground Lease Default, (iii) mitigating or attempting to mitigate any damages or consequences of the same and (iv) entry upon the applicable Ground Leased Tower Site for any or all of such purposes. Upon the Indenture Trustee’s or the Servicer’s request, each Issuer shall submit satisfactory evidence of payment or performance of any of its obligations under each Ground Lease. The Indenture Trustee or the Servicer may pay and expend such sums of money as the Indenture Trustee or the Servicer in its sole discretion deems necessary or desirable for any such purpose, and the Issuers shall pay to the Indenture Trustee or the Servicer, as applicable, within five Business Days of the written demand of the Indenture Trustee or the Servicer all such sums so paid or expended by the Indenture Trustee or the Servicer, as applicable, together with interest thereon from the date of expenditure at the then lowest Note Rate.

(e) Legal Action. The Issuers shall not commence any action or proceeding against any Ground Lessor or affecting or potentially affecting any Ground Lease or the Indenture Trustee and the Servicer’s interest therein, the effect of which could cause an event of default or termination of any such Ground Lease, without the prior written consent of the Indenture Trustee and the Servicer, which consent shall not be unreasonably withheld, conditioned or delayed. The Issuers promptly shall notify the Indenture Trustee and the Servicer if any action or proceeding shall be commenced between any Ground Lessor and an Issuer, or affecting or potentially affecting any Ground Lease or such Issuer’s or the Indenture Trustee’s and the Servicer’s interest therein (including, without limitation, any case commenced by or against any Ground Lessor under the Bankruptcy Code). The Issuers hereby grant the Indenture Trustee and the Servicer the option, exercisable upon notice from the Indenture Trustee or the Servicer to the applicable Issuer, to participate in any such action or proceeding with counsel of the Indenture Trustee’s or the Servicer’s choice. The Issuers shall cooperate with the Indenture Trustee and the Servicer, comply with the reasonable instructions of the Indenture Trustee and the Servicer, execute any and all powers, authorizations, consents or other documents reasonably required by the Indenture Trustee and the Servicer in connection therewith, and the Issuers shall not settle any such action or proceeding without the prior written consent of the Indenture Trustee and the Servicer, which consent shall not be unreasonably withheld, conditioned or delayed.

(f) Bankruptcy. (i) If any Ground Lessor shall reject any Ground Lease under or pursuant to Section 365 of the Bankruptcy Code, the Issuers shall not elect to treat the Ground Lease as terminated but shall elect to remain in possession of the applicable Ground Leased Tower Site and the leasehold estate under such Ground Lease.

(ii) The Issuers acknowledge and agree that in any case commenced by or against the Issuers under the Bankruptcy Code, the Indenture Trustee by reason of the liens and rights granted under the Transaction Documents shall have a substantial and material interest in the treatment and preservation of such Issuer’s rights and obligations under such Ground Lease, and that such Issuer shall, in any such bankruptcy case, provide to the Indenture Trustee immediate and continuous reasonably adequate protection of such interests. Each Issuer and the Indenture Trustee agree that such adequate protection shall include but shall not necessarily be limited to the following:

(A) The Indenture Trustee shall be deemed a party to the Ground Lease (but shall not have any obligations thereunder) for purposes of Section 365 of the Bankruptcy Code, and shall, provided that, prior to an Event of Default, no such action by the Indenture Trustee would adversely and materially affect the Issuers’ ability to prosecute, or defend, any such claims asserted therein, have standing to appear and act as a party in interest in relation to any matter arising out of or related to the Ground Lease or such Ground Leased Tower Site.

(B) The Issuers shall serve the Indenture Trustee and the Servicer with copies of all notices, pleadings and other documents relating to or affecting the Ground Lease or the applicable Ground Leased Tower Site. Any notice, pleading or document served by the Issuers on any other party in the bankruptcy case shall be contemporaneously served by such Issuer on the Indenture Trustee and the Servicer, and any notice, pleading or document served upon or received by such Issuer from any other party in the bankruptcy case shall be served by such Issuer on the Indenture Trustee and the Servicer promptly upon receipt by such Issuer.

(C) Upon written request of the Indenture Trustee (which shall be at the Servicer’s discretion), the Issuers shall assume the Ground Lease, and shall take such steps as are necessary to preserve such Issuer’s right to assume the Ground Lease, including without limitation using commercially reasonable efforts to obtain extensions of time to assume or reject the Ground Lease under Subsection 365(d) of the Bankruptcy Code to the extent it is applicable.

(g) If the Issuers or the applicable Ground Lessor seeks to reject any Ground Lease or have the Ground Lease deemed rejected, then prior to the hearing on such rejection the Indenture Trustee shall, subject to applicable law, be given no less than twenty (20) days’ notice and opportunity to elect in lieu of rejection to have the Ground Lease assumed and assigned to a nominee of the Indenture Trustee. If the Indenture Trustee shall so elect (which shall be at the Servicer’s direction) to assume and assign the Ground Lease, then the Issuers shall, subject to applicable law, continue any request to reject the Ground Lease until after the motion to assume and assign has been heard. If the Indenture Trustee shall not elect (which shall be at the Servicer’s direction) to assume and assign the Ground Lease, then the

Indenture Trustee may, subject to applicable law, obtain in connection with the rejection of the Ground Lease a determination that the applicable Ground Lessor, at the Indenture Trustee’s option (which shall be at the Servicer’s direction), shall (1) agree to terminate the Ground Lease and enter into a new lease with the Indenture Trustee on the same terms and conditions as the Ground Lease, for the Remaining Term of the Ground Lease, or (2) treat the Ground Lease as breached and provide the Indenture Trustee with the rights to cure defaults under the Ground Lease and to assume the rights and benefits of the Ground Lease.

Each Issuer shall join with and support any request by the Indenture Trustee to grant and approve the matters set forth in clause (g) as necessary for adequate protection of the Indenture Trustee’s interests. Notwithstanding the foregoing, the Indenture Trustee may seek additional terms and conditions, including such economic and monetary protections as it or the Servicer deems reasonably appropriate to adequately protect its interests, and any request for such additional terms or conditions shall not delay or limit the Indenture Trustee’s right to receive the specific elements of adequate protection set forth herein.

Each Issuer hereby appoints the Indenture Trustee as its attorney in fact to act on behalf of such Issuer in connection with all matters relating to or arising out of the assumption or rejection of any Ground Lease, in which the other party to the lease is a debtor in a case under the Bankruptcy Code. This grant of power of attorney is present, unconditional, irrevocable, durable and coupled with an interest.

SECTION 7.25. Easements. (a) Modification. Except as provided in this Section 7.25, the Issuers shall not modify or amend any material substantive or economic terms of, or, subject to the terms hereof, terminate or surrender any Easement, in each case without the prior written consent of the Indenture Trustee and the Servicer, which consent shall not be unreasonably withheld, conditioned or delayed. Any such attempted or purported material modification, amendment, or any surrender or termination of any Easement without the Indenture Trustee’s and the Servicer’s prior written consent shall be null and void and of no force or effect. Notwithstanding the foregoing to the contrary, the Issuers shall be permitted, without the Indenture Trustee’s and the Servicer’s consent, to:

(i) extend the terms of the Easement on commercially reasonable substantive and economic terms;

(ii) terminate any Easement which the Issuers reasonably deem necessary in accordance with prudent business practices; provided that (A) the Issuers provide written notice to the Indenture Trustee and the Servicer of such determination not later than thirty (30) days prior to such termination, (B) together with such notice the Issuers provide a certificate reasonably acceptable to the Servicer certifying that (on a pro forma basis) for such termination the projected DSCR for the 12-month period following such termination will be equal to or greater than the projected DSCR during such 12-month period assuming such termination did not occur (for purposes of calculating the DSCR during such

12-month period, the Issuer may give pro forma effect to the prospective impact on any of the items included in the calculation of the DSCR, including the projected costs associated with compliance with applicable environmental laws, increases in property taxes, costs associated with the renewal or modification of such Easement, and such other factors related to such particular Easement which could reasonably be expected to impact the DSCR) and (C) if (1) the aggregate Allocated Note Amount with respect to (x) each such Tower Site for which a termination has occurred under this Section 7.25(a), Section 7.10 and Section 7.24(a) and (y) the Tower Site for which a termination is proposed is greater than 5% of the aggregate Initial Class Principal Balance of all Classes of Notes, or (2) at least 78% of the Operating Revenues of the Tower Sites that remain following a proposed termination do not consist of wireless voice or data revenues, the Issuers shall have provided prior written notice to each Rating Agency.

(C) the Issuers shall pay or reimburse the Indenture Trustee and the Servicer for all reasonable costs and expenses incurred by the Indenture Trustee and the Servicer (including, without limitation, reasonable attorneys fees and disbursements) in connection with such Amended Easement, and all recording charges, filing fees, taxes or other expenses (including, without limitation, mortgage and intangibles taxes and documentary stamp taxes) payable in connection therewith; and

(D) if the aggregate Allocated Note Amount of all Tower Sites for which an Amended Easement has been executed exceeds 20% of the Initial Class Principal Balance of all Classes of Notes, the Issuers shall deliver a Rating Agency Confirmation from each Rating Agency to the Indenture Trustee and the Servicer.

(b) Performance of Easements. The Issuers shall fully perform as and when due each and all of its obligations under each Easement in accordance with the terms of such Easement, and shall not cause or suffer to occur any material breach or default in any of such obligations. Notwithstanding that certain of the obligations of the Issuers under this Indenture may be similar or identical to certain of the obligations of the Issuers under the Easements, all of the obligations of the Issuers under this Indenture are and shall be separate from and in addition to its obligations under the Easements.

(c) Notice of Default. If any of the Issuers shall have or receive any written notice that any Easement Default has occurred, then the Issuers promptly shall notify the Indenture Trustee and the Servicer in writing of the same and promptly deliver to the Indenture Trustee and the Servicer a true and complete copy of each such notice.

consequences of the same and (iv) entry upon the applicable Easement for any or all of such purposes.

If more than one of the foregoing paragraphs shall describe the same condition or event, then the Indenture Trustee shall have the right to select which paragraph or paragraphs shall apply. In any such case, the Indenture Trustee shall have the right (but not the obligation) to designate the paragraph or paragraphs which provide for nonwritten notice (or for no notice) or for a shorter time to cure (or for no time to cure).

SECTION 10.02. Acceleration and Remedies. (a) Upon the occurrence and during the continuance of any Event of Default, the Indenture Trustee may, and at the direction of the Noteholders representing more than 50% of the Voting Rights shall, declare all of the Notes immediately due and payable, by written notice in writing to the Issuers.

(ii) all Events of Default, other than the nonpayment of the principal of the Notes that has become due solely by such acceleration, have been cured or waived as provided in Section 10.15.

(c) Upon the occurrence and during the continuance of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge, all or any one or more of the rights, powers, privileges and other remedies available to the Indenture Trustee against the Issuers (or the Guarantor) under this Indenture or any of the other Transaction Documents, or at law or in equity, may be exercised by the Indenture Trustee at any time and from time to time, whether or not all or any of the Obligations shall be declared due and payable, and whether or not the Indenture Trustee shall have commenced any foreclosure proceeding or other action for the enforcement of its rights and remedies under any of the Transaction Documents with respect to the Tower Sites, the Assets, Leases or the Collateral and the proceeds from any of the foregoing. Any such actions taken by the Indenture Trustee shall be cumulative and concurrent and may be pursued independently, singly, successively, together or otherwise, at such time and in such order as the Indenture Trustee may determine in its sole discretion, to the fullest extent permitted by law, without impairing or otherwise affecting the other rights and remedies of the Indenture Trustee permitted by law, equity or contract or as set forth herein or in the other Transaction Documents.

102

the written direction of the Servicer, in its sole and absolute discretion, but subject to the Servicing Standard) toward the payment of any interest and/or principal of the Notes and/or any other amounts due under the Transaction Documents in such order, priority and proportions as the Indenture Trustee at the written direction of the Servicer (in its sole and absolute discretion, but subject to the Servicing Standard) shall determine; provided, however, that any such payments on the Notes and amounts due under the other Transaction Documents shall be made in accordance with the priorities set forth in Section 5.01.

(e) The rights and remedies set forth in this Section 10.02 are in addition to, and not in limitation of, any other right or remedy provided for in this Indenture or any other Transaction Document including, without limitation, the rights and remedies provided for in Section 10.08.

SECTION 10.03. Performance by Indenture Trustee. Upon the occurrence and during the continuance of an Event of Default, if any of the Issuers, the Guarantor or the Manager shall fail to perform, or cause to be performed, any material covenant, duty or agreement contained in any of the Transaction Documents (subject to applicable notice and cure periods), the Indenture Trustee may perform or attempt to perform such covenant, duty or agreement on behalf of such Issuer, the Guarantor or the Manager including making protective advances on behalf of any Issuers, or, in its sole discretion, causing the obligations of any of the Issuers to be satisfied with the proceeds of any Reserve. In such event, the Issuers shall, at the request of the Indenture Trustee, promptly pay to the Indenture Trustee, or reimburse, as applicable, any of the Reserves, any actual amount reasonably expended or disbursed by the Indenture Trustee in such performance or attempted performance, together with interest thereon (including reimbursement of any applicable Reserves), from the date of such expenditure or disbursement, until paid. Any amounts advanced or expended by the Indenture Trustee to perform or attempt to perform any such matter shall be added to and included within the Obligations and shall be secured by all of the Collateral securing the Notes. Notwithstanding the foregoing, it is expressly agreed that neither the Indenture Trustee nor the Servicer shall have any liability or responsibility for the performance of any obligation of the Issuers, the Guarantor or the Manager under this Indenture or any other Transaction Document, and it is further expressly agreed that no such performance by the Indenture Trustee or the Servicer shall cure any Event of Default hereunder.

SECTION 10.04. Evidence of Compliance. Promptly following request by the Indenture Trustee or the Servicer, the Issuers, the Guarantor or the Manager shall provide such documents and instruments as shall be reasonably satisfactory to the Indenture Trustee or the Servicer, as applicable, to evidence compliance with any material provision of the Transaction Documents applicable to such entities.

SECTION 10.05. Controlling Holders Representative. (a) The Noteholders (or, in the case of Book-Entry Notes, the Outstanding Note Owners) representing more than 50% of the Voting Rights of all Notes shall be entitled to select a representative (the “Controlling Holders Representative”) having the rights and powers specified in this Indenture and the other Transaction Documents (including those

103

specified in Section 10.06) or to replace an existing Controlling Holders Representative. Upon (i) the receipt by the Indenture Trustee of written requests for the selection of a Controlling Holders Representative from the Noteholders (or, in the case of Book-Entry Notes, the Note Owners) representing more than 50% of the Voting Rights of all Notes, (ii) the resignation or removal of the Person acting as Controlling Holders Representative, or (iii) the issuance of Additional Notes, the Indenture Trustee shall promptly notify the Issuers, Servicer and the Noteholders (and, in the case of Book-Entry Notes, to the extent actually known to a Responsible Officer of the Indenture Trustee or identified thereto by the Depositary, at the expense of the Noteholder or Note Owner requesting information with respect to clause (i) and clause (iii) above if the Depositary charges a fee for such identification, the Note Owners) that they may select a Controlling Holders Representative. Such notice shall set forth the process established by the Indenture Trustee for selecting a Controlling Holders Representative. No appointment of any Person as a Controlling Holders Representative shall be effective until such Person provides the Indenture Trustee with written confirmation of its acceptance of such appointment, written confirmation that it will keep confidential all information received by it as Controlling Holders Representative or otherwise with respect to the Notes, the Assets and/or the Transaction Documents, an address and facsimile number for the delivery of notices and other correspondence and a list of officers or employees of such Person with whom the parties to the Transaction Documents may deal (including their names, titles, work addresses and facsimile numbers). No Affiliate of the Issuers may act as Controlling Holders Representative.

(b) Within 10 Business Days (or as soon thereafter as practicable if the Controlling Holders consists of Book-Entry Notes) of any change in the identity of the Controlling Holders Representative of which a Responsible Officer of the Indenture Trustee has actual knowledge, the Indenture Trustee shall deliver to the Noteholders or Note Owners, as applicable, and the Servicer a notice setting forth the identity of the new Controlling Holders Representative and a list of each Noteholder (or, in the case of Book-Entry Notes, to the extent actually known to a Responsible Officer of the Indenture Trustee or identified thereto by the Depositary or the DTC Participants, each Note Owner), including, in each case, names and addresses. With respect to such information, the Indenture Trustee shall be entitled to rely conclusively on information provided to it by the Noteholders (or, in the case of Book-Entry Notes, subject to Section 2.06, by the Depositary or the Note Owners) of the Notes, and the Servicer shall be entitled to rely on such information provided by the Indenture Trustee with respect to any obligation or right hereunder that the Servicer may have to deliver information or otherwise communicate with the Controlling Holders Representative or any of the Noteholders (or, if applicable, Note Owners). In addition to the foregoing, within two Business Days of the selection, resignation or removal of a Controlling Holders Representative, the Indenture Trustee shall notify the parties to this Indenture of such event.

(c) A Controlling Holders Representative may at any time resign as such by giving written notice to the Indenture Trustee and to each Noteholder (or, in the case of Book-Entry Notes, each Note Owner). The Noteholders (or, in the case of Book-Entry Notes, the Note Owners) representing more than 50% of the Voting

104

Rights of all Notes shall be entitled to remove any existing Controlling Holders Representative by giving written notice to the Indenture Trustee and to such existing Controlling Holders Representative.

(d) Once a Controlling Holders Representative has been selected pursuant to this Section 10.05, each of the parties to the Transaction Documents and each Noteholder (or Note Owner, if applicable) shall be entitled to rely on such selection unless Noteholders (or, in the case of Book-Entry Notes, the Note Owners) representing more than 50% of the Voting Rights of all Notes, or such Controlling Holders Representative, as applicable, shall have notified the Indenture Trustee and each other party to the Transaction Documents and each Noteholder (or, in the case of Book-Entry Notes, Note Owner), in writing, of the resignation or removal of such Controlling Holders Representative.

(e) Any and all expenses of the Controlling Holders Representative shall be borne pro rata by the Noteholders (or, if applicable, the Note Owners) (with any costs incurred in connection therewith being deemed to be reimbursable Additional Issuer Expense) of all Notes. Notwithstanding the foregoing, if a claim is made against the Controlling Holders Representative by an Issuer with respect to the Transaction Documents or the Notes, the Controlling Holders Representative shall immediately notify the Indenture Trustee and the Servicer, whereupon (if the Servicer or the Indenture Trustee are also named parties to the same action and, in the sole judgment of the Servicer, (i) the Controlling Holders Representative had acted in good faith, without gross negligence or wilful misconduct, with regard to the particular matter at issue, and (ii) there is no potential for the Servicer or the Indenture Trustee to be an adverse party in such action as regards the Controlling Holders Representative) the Servicer on behalf of the Indenture Trustee shall, subject to the Transaction Documents, assume the defense of any such claim against the Controlling Holders Representative.

SECTION 10.06. Certain Rights and Powers of the Controlling Holders Representative. (a) At any time that the Servicer proposes to transfer the ownership of a Tower Site or the ownership of the direct or indirect equity interests of any of the Issuers, the Controlling Holders Representative shall be entitled to advise the Servicer with respect to such transfer, and notwithstanding anything in any other Section of this Indenture to the contrary, but in all cases subject to Section 10.06(b), the Servicer shall not be permitted to take such action if the Controlling Holders Representative has objected in writing within 10 Business Days of having been notified thereof and having been provided with information with respect thereto reasonably requested no later than the fifth Business Day after notice thereof (provided that if such written objection has not been received by the Servicer within such 10 Business Day period, then the Controlling Holders Representative’s approval shall be deemed to have been given).

If the Controlling Holders Representative affirmatively approves or is deemed to have approved in writing such a request, the Servicer shall implement the action for which approval was sought. If the Controlling Holders Representative disapproves of such a request within the 10 Business Day period referred to in the

105

preceding paragraph, the Servicer must (unless it withdraws the request) revise the request and deliver to the Controlling Holders Representative a revised request promptly and in any event within 30 days after such disapproval. The Servicer shall be required to implement the action for which approval was most recently requested (unless such request was withdrawn by the Servicer) upon the earlier of (x) the failure of the Controlling Holders Representative to disapprove a request within 10 Business Days after its receipt thereof and (y) (1) the passage of 60 days following the Servicer’s delivery of its initial request to the Controlling Holders Representative and (2) the determination by the Servicer in its reasonable good faith judgment that the failure to implement the most recently requested action would violate the Servicer’s obligation to act in accordance with the Servicing Standard.

(b) Notwithstanding anything herein to the contrary, (i) the Servicer shall not have any right or obligation to consult with or to seek and/or obtain consent or approval from any Controlling Holders Representative prior to acting, and provisions of the Servicing Agreement requiring such shall be of no effect, during the period prior to the initial selection of a Controlling Holders Representative and, if any Controlling Holders Representative resigns or is removed, during the period following such resignation or removal until a replacement is selected and (ii) no advice, direction or objection from or by the Controlling Holders Representative, as contemplated by Section 10.06(a), may (A) require or cause the Servicer to violate applicable law, the terms of the Notes or any Transaction Document, including the Servicer’s obligation to act in accordance with the Servicing Standard, (B) expose the Servicer or the Indenture Trustee, or any of their respective Affiliates, officers, directors, members, managers, employees, agents or partners, to any material claim, suit or liability, or (C) materially expand the scope of the Servicer’s responsibilities under the Servicing Agreement or this Indenture. In addition, the Controlling Holders Representative may not prevent the Servicer from transferring the ownership of a Tower Site or the ownership of any of the direct or indirect equity interests of the Issuers (including by way of foreclosure on the equity interests of the Issuers) if any Nonrecoverable Advance is outstanding and the Servicer determines in accordance with the Servicing Standard that such foreclosure would be in the best interest of the Noteholders (taken as a whole).

The Controlling Holders Representative shall not be liable to the Noteholders for any action taken, or for refraining from the taking of any action, in good faith pursuant to the Transaction Documents, or for errors in judgment; provided, however, that the Controlling Holders Representative shall not be protected against any liability which would otherwise be imposed by reason of wilful misfeasance, gross negligence or reckless disregard of obligations or duties under the Transaction Documents. Each Noteholder and Note Owner acknowledges and agrees, by its acceptance of its Notes or interest therein, that the Controlling Holders Representative may have special relationships and interests that conflict with those of Noteholders and Note Owners of one or more Classes of Notes, that the Controlling Holders Representative does not have any duties to the Noteholders and Note Owners of any Class of Notes, that the Controlling Holders Representative may take actions that favor the interests of the Noteholders and Note Owners of one or more Classes of Notes over

106

the interests of the Noteholders and Note Owners of a different Class of Notes, that the Controlling Holders Representative shall not be deemed to have been grossly negligent or reckless, or to have acted in bad faith or engaged in wilful misfeasance by reason of its having acted solely in the interests of one Class of Notes and that the Controlling Holders Representative shall have no liability whatsoever for having so acted, and no Noteholder may take any action whatsoever against the Controlling Holders Representative for having so acted or against any director, officer, employee, agent or principal thereof for having so acted.

SECTION 10.07. Collection of Indebtedness and Suits for Enforcement by Indenture Trustee. (a) Subject to the provisions of Section 10.02, the Issuers covenant that if there is an Event of Default described in Section 10.01(a), the Issuers shall pay to the Indenture Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on such Notes for the Outstanding Class Principal Balance of all Classes of Notes and interest, with interest upon the overdue principal and, to the extent payment at such rate of interest shall be legally enforceable, upon overdue installments of interest at the rate borne by the relevant Notes and in addition thereto all other Obligations, including, but not limited to, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and the Servicer and their respective agents and counsel and other amounts due and owing to the Indenture Trustee and the Servicer hereunder and under the Transaction Documents.

(b) Subject to the provisions of Section 10.02 and Section 16.16, in case the Issuers shall fail forthwith to pay such amounts upon such demand, the Indenture Trustee, in its own name and as trustee of an express trust, may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuers or other obligor upon such Notes and collect in the manner provided by law out of the property of the Issuers or other obligor upon such Notes wherever situated, the monies adjudged or decreed to be payable.

(c) Subject to the provisions of Section 16.16, if an Event of Default occurs and is continuing, the Indenture Trustee may, as more particularly provided in Section 10.08, in its discretion, proceed to protect and enforce its rights and the rights of the Noteholders, by such appropriate Proceedings as the Indenture Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or any Indenture Supplement or in aid of the exercise of any power granted in this Indenture or any Indenture Supplement, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or any Indenture Supplement or by law.

(d) In case there shall be pending, relative to the Issuers or any other obligor upon the Notes, proceedings under any applicable Federal, state or foreign bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have

107

been appointed for or taken possession of the Issuers or their property or such other obligor, or in case of any other comparable judicial Proceedings relative to the Issuers or other obligor upon the Notes, or to the creditors or property of the Issuers or such other obligor, the Indenture Trustee, irrespective of whether the Outstanding Class Principal Balance shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

(i) to file and prove a claim or claims for the whole amount of the principal and interest owing and unpaid in respect of Notes, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee (including any claim for reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and each predecessor indenture trustee, and their respective agents, attorneys and counsel, and all other amounts due and owing to the Indenture Trustee pursuant to Section 11.05 and all other amounts due and owing to the Servicer under the Servicing Agreement) and of the Noteholders allowed in such Proceedings;

(ii) unless prohibited by applicable law and regulations, to vote on behalf and at the direction of the Noteholders in any election of a trustee, a standby trustee or Person performing similar functions in any such Proceedings;

(iii) to collect and receive any monies or other property payable or deliverable on any such claims and to pay all amounts received with respect to the claims of the Noteholders and of the Indenture Trustee on their behalf; and

(iv) 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 Indenture Trustee or the Noteholders allowed in any judicial proceedings relative to the Issuers, their creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in any such Proceeding is hereby authorized by each of such Noteholders to make payments to the Indenture Trustee and, in the event that the Indenture Trustee shall consent to the making of payments directly to such Noteholders, to pay to the Indenture Trustee such amounts as shall be sufficient to cover reasonable compensation to the Indenture Trustee, each predecessor indenture trustee and their respective agents, attorneys and counsel, and all other amounts due and owing to the Indenture Trustee pursuant to Section 11.05 and all other amounts due and owing to the Servicer under the Servicing Agreement.

(e) Nothing contained in this Indenture or in any Indenture Supplement shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any such Noteholder in any such Proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person and be a member of a creditors’ or other similar committee.

108

(f) Subject to the provisions of Section 16.16, all rights of action and of asserting claims under this Indenture or in any Indenture Supplement, or under any of the Notes, may be enforced by the Indenture Trustee without the possession of the Notes or the production thereof in any trial or other Proceedings relative thereto, and any such action or Proceedings instituted by the Indenture Trustee may be brought in its own name and as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements, advances, amounts owed to and compensation of the Indenture Trustee, each predecessor indenture trustee and their respective agents and attorneys, shall be for the benefit of the Noteholders.

(g) In any Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this Indenture or any Indenture Supplement to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all the Noteholders, and it shall not be necessary to make any Noteholder a party to any such Proceedings.

SECTION 10.08. Remedies. If an Event of Default shall have occurred and be continuing, the Indenture Trustee may do one or more of the following (subject to Section 10.02, Section 10.09, and Section 16.16):

(i) institute Proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the Notes or under this Indenture, any Indenture Supplement or any other Transaction Document with respect thereto, whether by declaration or otherwise, enforce any judgment obtained and collect from the Issuers and any other obligor upon such Notes, this Indenture, any Indenture Supplement or any other Transaction Document monies adjudged due;

(ii) institute Proceedings from time to time for the complete or partial foreclosure of this Indenture or any Indenture Supplement with respect to the Trust Estate;

(iii) exercise any and all rights and remedies of a secured party under applicable law of any relevant jurisdiction or in equity and take any other appropriate action to protect and enforce the rights and remedies of the Indenture Trustee and the Noteholders;

(iv) sell the Trust Estate or any portion thereof or rights or interest therein, at one or more public or private sales called and conducted in any manner permitted by law;

(v) without notice to the Issuers, except as required by law and as otherwise provided in this Indenture, and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Collateral against the Obligations or any part thereof; and

109

(vi) demand, collect, take possession of, receive, settle, compromise, adjust, sue for, foreclose or realize upon the Collateral (or any portion thereof) as the Indenture Trustee may determine in its sole discretion.

SECTION 10.09. Optional Preservation of the Trust Estate. If the Notes have been declared to be due and payable under Section 10.02 following an Event of Default, and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may, but need not, with the consent of Noteholders representing more than 50% of the aggregate Outstanding Class Principal Balance, elect to maintain possession of the Trust Estate and apply proceeds as if there had been no declaration of acceleration. It is the desire of the Issuers and the Noteholders that there be at all times sufficient funds for the payment of all Obligations, including, but not limited to, the Outstanding Class Principal Balance of and interest on all Classes of Notes, and the Indenture Trustee shall take such desire into account when determining whether or not to maintain possession of the Trust Estate. In determining whether to maintain possession of the Trust Estate, the Indenture Trustee may, at the Issuers’ expense, but need not, obtain and shall be protected in relying upon an opinion of an Independent investment banking or accounting firm of international reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose.

SECTION 10.10. Limitation of Suits. Subject to the provisions of Section 16.16, no Noteholder shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture or any Indenture Supplement or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(a) such Holder has previously given written notice to the Indenture Trustee of a continuing Event of Default;

(b) Noteholders by an Affirmative Direction have, made written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as the Indenture Trustee hereunder;

(c) such Holder or Holders has offered to the Indenture Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in complying with such request;

(d) the Indenture Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute such Proceedings; and

(e) no direction inconsistent with such written request has been given to the Indenture Trustee during such 60 day period by Noteholders representing more than 50% of the Outstanding Class Principal Balance of all Classes of Notes.

110

It is understood and intended that no one or more Noteholders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Indenture or any Indenture Supplement to affect, disturb or prejudice the rights of any other Noteholders or to obtain or to seek to obtain priority or preference over any other Noteholders or to enforce any right under this Indenture or any Indenture Supplement, except in the manner provided in this Indenture.

In the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Noteholders, each representing less than a majority of the Outstanding Class Principal Balance of all Classes of Notes, the Indenture Trustee in its sole discretion may determine what action, if any, shall be taken, notwithstanding any other provisions of this Indenture or any Indenture Supplement. Notwithstanding any provision of this Section 10.10, the Indenture Trustee shall not take any action or permit any action to be taken that is inconsistent with Section 16.16.

SECTION 10.11. Unconditional Rights of Noteholders to Receive Principal and Interest. Notwithstanding any other provisions in this Indenture or any Indenture Supplement, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Note on or after the respective due dates thereof expressed in such Note or in this Indenture or any Indenture Supplement, and such right shall not be impaired without the consent of such Holder.

SECTION 10.12. Restoration of Rights and Remedies. If the Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture or any Indenture Supplement and such Proceeding has been discontinued or abandoned for any reason or has been determined adversely to the Indenture Trustee or to such Noteholder, then thereafter all rights and remedies of the Indenture Trustee and the Noteholders shall continue as though no such Proceeding had been instituted.

SECTION 10.13. Rights and Remedies Cumulative. Except as provided herein, no right or remedy conferred in this Indenture, in any Indenture Supplement or in any other Transaction Document upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder, in any Indenture Supplement or in any other Transaction Document or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, in any Indenture Supplement, or in any other Transaction Document or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 10.14. Delay or Omission Not a Waiver. No delay or omission of the Indenture Trustee or any Holder of any Note to exercise any right or remedy accruing upon any Default or Event of Default shall impair any such right or remedy or constitute a waiver of any such Default or Event of Default or any acquiescence therein. Every right and remedy given by this Article X or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

111

SECTION 10.15. Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Notes as provided in Section 10.02 as may be modified by any Indenture Supplement, Noteholders representing more than 50% of the Outstanding Class Principal Balance of all Classes of Notes may waive any past Default or Event of Default and its consequences except (i) a Default (a) in the payment of principal of or interest on any of the Notes or (b) in respect of a covenant or provision hereof that cannot be amended, supplemented or modified without the consent of each Noteholder and (ii) before any such waiver may be effective, the Indenture Trustee and the Servicer must receive any reimbursement then due or payable in respect of unreimbursed Advances (including Advance Interest thereon) or any other amounts then due to the Servicer or the Indenture Trustee hereunder or under the other Transaction Documents (including, but not limited to, outstanding Advances, Advance Interest, unpaid Additional Issuer Expenses, and all unpaid fees, expenses, and indemnification due to the Servicer and the Indenture Trustee hereunder and under the other Transaction Documents). Upon any such waiver, such Default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for every purpose of this Indenture or any Indenture Supplement; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

SECTION 10.16. Undertaking for Costs. All parties to this Indenture or any Indenture Supplement agree, and each Holder of any Note by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or any Indenture Supplement, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as the Indenture Trustee, the filing by any party litigant (other than an Issuer) in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees, against any party litigant (other than an Issuer) in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant (other than an Issuer); but the provisions of this Section 10.16 as may be modified by any Indenture Supplement shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of Noteholders, representing more than 10% of the Outstanding Class Principal Balance of all Classes of Notes or (c) any suit instituted by any Noteholder for the enforcement of the payment of the principal balance of any Note or interest on any Note on or after the respective due dates expressed in such Note and in this Indenture or any Indenture Supplement.

SECTION 10.17. Waiver of Stay or Extension Laws. The Issuers covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, or plead or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, any Indenture Supplement or any Transaction Document; and the Issuers (to the extent that they may lawfully do so)

112

hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not hinder, delay or impede the execution of any power granted in this Indenture to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 10.18. Action on Notes. The Indenture Trustee’s right to seek and recover judgment on the Notes or under this Indenture, any Indenture Supplement or any Transaction Document shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture, any Indenture Supplement or any Transaction Document. No rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuers or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the Assets of the Issuers.

SECTION 10.19. Waiver. The Issuers hereby expressly waive, to the fullest extent permitted by law, presentment, demand, protest or any notice of any kind in connection with this Indenture or the Collateral. The Issuers acknowledge and agree that 10 days’ prior written notice of the time and place of any public sale of the Collateral or any other intended disposition thereof shall be reasonable and sufficient notice to the Issuers within the meaning of the UCC.

ARTICLE XI

The Indenture Trustee

SECTION 11.01. Duties of Indenture Trustee. (a) The Indenture Trustee, prior to the occurrence of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge and after the curing or waiving of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. If an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge occurs and is continuing, the Indenture Trustee (or the Servicer on its behalf) shall exercise such of the rights and powers vested in it by this Indenture, any Indenture Supplement and any other Transaction Document, and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of its own affairs (provided that the Servicer shall act in accordance with the Servicing Standard). Any permissive right of the Indenture Trustee contained in this Indenture, any Indenture Supplement and any other Transaction Document shall not be construed as a duty. The Indenture Trustee shall be liable in accordance herewith only to the extent of the respective obligations specifically imposed upon and undertaken by the Indenture Trustee.

(b) Upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Indenture Trustee which are specifically required to be furnished pursuant to any provision of this Indenture, any Indenture Supplement and any other Transaction Document, the

113

Indenture Trustee shall examine them to determine whether they conform on their face to the requirements of this Indenture, any Indenture Supplement or any other Transaction Document (but need not confirm or investigate the accuracy or mathematical calculations or other facts stated therein). If any such instrument is found not to conform on its face to the requirements of this Indenture, any Indenture Supplement, or any other Transaction Document in a material manner, the Indenture Trustee shall take such action as it deems appropriate to have the instrument corrected. The Indenture Trustee shall not be responsible or liable for the accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument furnished by the Issuers, Crown International, the Manager, the Servicer, the Controlling Holders Representative, any actual or prospective Noteholder or Note Owner or any Rating Agency, and accepted by the Indenture Trustee in good faith, pursuant to this Indenture and any Indenture Supplement.

(c) No provision of this Indenture shall be construed to relieve the Indenture Trustee from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct; provided, however, that:

(i) Prior to the occurrence of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge, and after the curing or waiving of all Events of Default which may have occurred, the duties and obligations of the Indenture Trustee shall be determined solely by the express provisions of this Indenture, the Indenture Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture or any Indenture Supplement and no implied covenants or obligations shall be read into this Indenture or any Indenture Supplement against the Indenture Trustee.

(ii) In the absence of bad faith on the part of the Indenture Trustee, the Indenture Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Indenture Trustee and conforming to the requirements of this Indenture and any Indenture Supplement.

(iii) The Indenture Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Indenture Trustee unless it shall be proved that the Indenture Trustee was negligent in ascertaining the pertinent facts.

(iv) The Indenture Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by the Indenture Trustee, in good faith in accordance with this Indenture (including at the direction of the Servicer) or the direction of Noteholders entitled to more than 50% (or, as to any particular matter, any higher percentage as may be specifically provided for hereunder) of the Voting Rights relating to the time, method and place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred upon the Indenture Trustee, under this Indenture.

114

(v) The Indenture Trustee shall not be required to take notice or be deemed to have notice or be deemed to have notice or knowledge of any Event of Default unless either (1) a Responsible Officer shall have actual knowledge of such Event of Default or (2) written notice of such Event of Default referring to the Notes, this Indenture and any Indenture Supplement shall have been received by a Responsible Officer in accordance with the provisions of this Indenture and any Indenture Supplement. In the absence of receipt of such notice or actual knowledge, the Indenture Trustee may conclusively assume that there is no Event of Default.

(vi) Subject to the other provisions of this Indenture, and without limiting the generality of this Section 11.01, the Indenture Trustee shall not have any duty, except as expressly provided herein or in any Indenture Supplement, or in its capacity as successor servicer, (A) to cause any recording, filing, or depositing of this Indenture or any Indenture Supplement or any agreement referred to herein or therein or any financing statement or continuation statement evidencing a security interest, or to cause the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to or cause the maintenance of any insurance, (C) to confirm or verify the truth, accuracy or contents of any reports or certificates of the Issuers, Crown International, the Manager, the Servicer, the Controlling Holders Representative, any Noteholder or Note Owner or any Rating Agency, delivered to the Indenture Trustee pursuant to this Indenture reasonably believed by the Indenture Trustee to be genuine and to have been signed or presented by the proper party or parties (provided, however, that the Indenture Trustee may, in its discretion, make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Indenture Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuers personally or by agent or attorney), and (D) to see to the payment of any assessment or other governmental charge or any Lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Collateral other than from funds available in the Central Account (provided that such assessment, charge, Lien or encumbrance did not arise out of the Indenture Trustee’s wilful misfeasance, bad faith or gross negligence).

(vii) None of the provisions contained in this Indenture or any Indenture Supplement shall in any event require the Indenture Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Servicer under the Servicing Agreement except during such time, if any, as the Indenture Trustee shall be successor to, and be vested with the rights, duties, powers and privileges of, the Servicer in accordance with the terms of this Indenture and the Servicing Agreement.

(viii) For as long as the Person that serves as the Indenture Trustee hereunder also serves as Note Registrar or Paying Agent, the protections, immunities and indemnities afforded to that Person in its capacity as the Indenture Trustee hereunder shall also be afforded to such Person in its capacity as Note Registrar or Paying Agent, as the case may be.

115

(ix) If the same Person is acting in as the Indenture Trustee and Note Registrar, then any notices required to be given by such Person in one such capacity shall be deemed to have been timely given to itself in any other such capacity.

(d) The Indenture Trustee is hereby directed to execute and deliver the Deposit Account Control Agreement.

(e) The Indenture Trustee shall not be liable for interest on any money received by it except as the Indenture Trustee may agree in writing with the Issuers.

(f) Money held in trust by the Indenture Trustee need not be segregated from other funds except to the extent required by law, this Indenture or any Indenture Supplement.

(g) Every provision in this Indenture and any Indenture Supplement that in any way relates to the Indenture Trustee is subject to paragraphs (a) through (f) of this Section 11.01.

SECTION 11.02. Certain Matters Affecting the Indenture Trustee. Except as otherwise provided in Section 11.01:

(i) the Indenture Trustee may rely upon and shall be protected in acting or refraining from acting upon any resolution, Officers’ Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties;

(ii) the Indenture Trustee may consult with counsel and any advice or opinion of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance therewith;

(iii) the Indenture Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture or any Indenture Supplement or to make any investigation of matters arising hereunder or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Noteholders, unless such Noteholders shall have provided to the Indenture Trustee security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby satisfactory to the Indenture Trustee, in its sole discretion; the Indenture Trustee shall not be required to expend or risk its own funds (except to pay expenses that could reasonably be expected to be incurred in connection with the performance of its normal duties)

116

or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not assured to it; provided, however, that nothing contained herein shall relieve the Indenture Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge which has not been waived or cured, to exercise such of the rights and powers vested in it by this Indenture or any Indenture Supplement, and to use the same degree of care and skill in their exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs;

(iv) the Indenture Trustee shall not be personally liable for any action reasonably taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture on any Indenture Supplement;

(viii) the Indenture Trustee shall not be responsible for any act or omission of the Servicer or any act or failure to act taken by the Indenture Trustee at the written direction of the Servicer (unless, in the case of the Indenture Trustee, it is acting as Servicer); and

117

(ix) the Indenture Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance with any restriction on transfer imposed under Article II under this Indenture or under applicable law with respect to any transfer of any Note or any interest therein, other than to require delivery of the certification(s) and/or Opinions of Counsel described in said Article applicable with respect to changes in registration or record ownership of Notes in the Note Register and to examine the same to determine substantial compliance with the express requirements of this Indenture; and the Indenture Trustee and the Note Registrar shall have no liability for transfers, including transfers made through the book-entry facilities of the Depositary or between or among DTC Participants or Note Owners of the Notes, made in violation of applicable restrictions except for its failure to perform its express duties in connection with changes in registration or record ownership in the Note Register.

SECTION 11.03. Indenture Trustee’s Disclaimer. The Indenture Trustee (i) shall not be responsible for, and makes no representation, as to the validity or adequacy of this Indenture, any Indenture Supplement or the Notes and (ii) shall not be accountable for the Issuers’ use of the proceeds from the Notes, or responsible for any statement of the Issuers in this Indenture, any Indenture Supplement or in any document issued in connection with the sale of the Notes or in the Notes other than the Indenture Trustee’s certificate of authentication.

SECTION 11.04. Indenture Trustee May Own Notes. The Indenture Trustee (in its individual or any other capacity) or any of its respective Affiliates may become the owner or pledgee of Notes with (except as otherwise provided in the definition of “Noteholder”) the same rights it would have if it were not the Indenture Trustee or one of its Affiliates, as the case may be.

SECTION 11.05. Fees and Expenses of Indenture Trustee; Indemnification of and by the Indenture Trustee. (a) On each Payment Date, the Indenture Trustee shall withdraw from the Central Account, out of general collections on the Notes on deposit therein, prior to any payments to be made therefrom to Noteholders on such date, and pay to itself all Indenture Trustee Fees earned in respect of the Notes through the end of then most recently ended Collection Period as compensation for all services rendered by the Indenture Trustee, respectively, hereunder. The Indenture Trustee Fee shall accrue during each Collection Period at the rate per annum equal to 0.009% on the Outstanding Class Principal Balance of all Classes of Notes as of the end of the immediately preceding Collection Period (or, in the case of the initial Collection Period, on a principal balance equal to $250,000,000); provided that the Indenture Trustee Fee shall not be less than $8,500 for any year. The Indenture Trustee Fee shall be calculated on a 30/360 Basis.

118

(b) The Indenture Trustee and any of its Affiliates, directors, officers, employees or agents shall be entitled to be indemnified and held harmless out of the funds on deposit in the Central Account for and against any loss, liability, claim or expense (including costs and expenses of litigation, and of investigation, reasonable counsel’s fees, damages, judgments and amounts paid in settlement) arising out of, or incurred in connection with, this Indenture, the Notes (unless, in the case of the Indenture Trustee, it incurs any such expense or liability in the capacity of successor Servicer, in which case such expense or liability shall be reimbursable thereto in the same manner as it would be for any other Servicer in accordance with the Servicing Agreement), or any act or omission of the Indenture Trustee (including any act or failure to act taken at the written direction of the Servicer) relating to the exercise and performance of any of the rights and duties of the Indenture Trustee hereunder; provided, however, that none of the Indenture Trustee or any of the other above specified Persons shall be entitled to indemnification or reimbursement pursuant to this Section 11.05(b) for loss, liability, damage, claim or expense incurred by reason of any wilful misfeasance, bad faith or gross negligence in the performance of, or reckless disregard of, such Person’s obligations and duties hereunder. Without limiting the foregoing, the Issuers agree to indemnify and hold harmless the Indenture Trustee and its Affiliates from and against any liability (including for taxes, penalties or interest asserted by any taxing jurisdiction) arising from any failure to withhold taxes from amounts payable in respect of payments from the Central Account. The Indenture Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Indenture Trustee to so notify the Issuers shall not relieve the Issuers of their obligations hereunder. To the extent the Indenture Trustee (or the Servicer on its behalf) renders services or incurs expenses after an Event of Default specified in Section 10.01(f) or Section 10.01(g), the compensation for services and expenses incurred by it are intended to constitute expenses of administration under any applicable Federal, state or foreign bankruptcy, insolvency or other similar law now or hereafter in effect. The Indenture Trustee (for itself and on behalf of the Servicer) shall have a Lien on the Collateral, as governed by this Indenture, to secure the obligations of the Issuers under this Section 11.05.

(c) Notwithstanding anything in this Indenture to the contrary, in no event shall the Indenture Trustee be liable for special, indirect, or consequential damages of any kind whatsoever (including but not limited to lost profits), even if the Indenture Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(d) This Section 11.05 shall survive the termination of this Indenture or the resignation or removal of the Indenture Trustee as regards rights and obligations prior to such termination, resignation or removal.

SECTION 11.06. Eligibility Requirements for Indenture Trustee. The Indenture Trustee hereunder shall not be an Affiliate of the Servicer or any Issuer (unless the Indenture Trustee is a successor servicer) and shall at all times be a corporation, bank, trust company or association that: (i) is organized and doing business under the laws of the United States of America or any State thereof or the District of Columbia and authorized under such laws to exercise corporate trust powers; (ii) has a combined capital

119

and surplus of at least $100,000,000; and (iii) is subject to supervision or examination by Federal or state authority. If such corporation, bank, trust company or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation, bank, trust company or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In addition: (i) the Indenture Trustee shall at all times meet the requirements of Section 26(a)(1) of the Investment Company Act; and (ii) the Indenture Trustee may not have any affiliations or act in any other capacity with respect to the transactions contemplated hereby that would cause PTE 90-24 or PTE 93-31 (in each case as amended by PTE 2000-58 and PTE 2002-41) to be unavailable with respect to any Class of Notes that it would otherwise be available in respect of. Furthermore, the Indenture Trustee or its parent shall at all times maintain (or shall have caused to have been appointed a fiscal agent that at all times maintains) a long-term unsecured debt rating of no less than “A” from Fitch and “A2” from Moody’s and a short-term unsecured debt rating of no less than “F-1” from Fitch and “P-1” from Moody’s (or such lower rating with respect to which the Indenture Trustee shall have received Rating Agency Confirmation from the Rating Agencies assigning such rating). The corporation, bank, trust company or association serving as the Indenture Trustee may have normal banking and trust relationships with the Issuers, the Servicer and their respective Affiliates but, except to the extent permitted or required by the Servicing Agreement, shall not be an “Affiliate” (as such term is defined in Section III of PTE 2000-58) of the Servicer, any sub-servicer, either Initial Purchaser, the Issuers or any “Affiliate” (as such term is defined in Section III of PTE 2000-58) of any such Persons.

SECTION 11.07. Resignation and Removal of Indenture Trustee. (a) The Indenture Trustee may at any time resign and be discharged from its obligations and duties created hereunder with respect to one or more or all Series of Notes by giving not less that 60 days’ prior written notice thereof to the other parties to this Indenture, the Servicer and all of the Noteholders. Upon receiving such notice of resignation, the Issuers shall use their best efforts to promptly appoint a successor indenture trustee meeting the eligibility requirements of Section 11.06 by written instrument, in duplicate, which instrument shall be delivered to the resigning Indenture Trustee and to the successor indenture trustee. A copy of such instrument shall be delivered to the other parties to this Indenture, the Servicer and to the Noteholders by the Issuers. If no successor indenture trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Indenture Trustee may petition any court of competent jurisdiction for the appointment of a successor indenture trustee.

(b) If at any time the Indenture Trustee shall cease to be eligible in accordance with the provisions of Section 11.06 and shall fail to resign after written request therefor by the Issuers or the Servicer, or if at any time the Indenture Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Indenture Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Indenture Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or if the

120

Indenture Trustee’s continuing to act in such capacity would (as confirmed in writing to the Issuers by Fitch) result in the qualification, downgrade or withdrawal of the rating then assigned to any Class of Notes rated by Fitch (or the placing of such Class of Notes on negative credit watch or ratings outlook negative status in contemplation of any such action with respect thereto), notice shall be provided to Moody’s, and the Issuers, or the Noteholders entitled to more than 50% of the Voting Rights, may remove the Indenture Trustee and appoint a successor indenture trustee by written instrument, in duplicate, which instrument shall be delivered to the Indenture Trustee so removed and to the successor indenture trustee. A copy of such instrument shall be delivered to the other parties to this Indenture, the Servicer and the Noteholders by the Issuers.

(c) The holders of Notes entitled to more than 50% of the Voting Rights may at any time (with or without cause) remove the Indenture Trustee and appoint a successor indenture trustee by written instrument or instruments, in triplicate, signed by such holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Issuers, one complete set to the Indenture Trustee so removed, and one complete set to the successor indenture trustee so appointed. All expenses incurred by the Indenture Trustee in connection with its transfer of all documents relating to the Notes to a successor indenture trustee following the removal of the Indenture Trustee without cause pursuant to this Section 11.07(c) shall be reimbursed to the removed the Indenture Trustee within 30 days of demand therefor, such reimbursement to be made by the Noteholders that terminated the Indenture Trustee. A copy of such instrument shall be delivered to the other parties to this Indenture, the Servicer and the remaining Noteholders by the successor indenture trustee so appointed.

(d) Any resignation or removal of the Indenture Trustee and appointment of a successor indenture trustee pursuant to any of the provisions of this Section 11.07 shall not become effective until acceptance of appointment by the successor indenture trustee as provided in Section 11.08.

SECTION 11.08. Successor Indenture Trustee. (a) Any successor indenture trustee appointed as provided in Section 11.07 shall execute, acknowledge and deliver to the Issuers, the Servicer and its predecessor indenture trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor indenture trustee shall become effective and such successor indenture trustee, without any further act, deed or conveyance, shall become fully vested with all of the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as the Indenture Trustee herein. The predecessor indenture trustee shall deliver to the successor indenture trustee all documents relating to the Notes held by it hereunder, and the Issuers, the Servicer and the predecessor indenture trustee shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and certainly vest and confirm in the successor indenture trustee all such rights, powers, duties and obligations, and to enable the successor indenture trustee to perform its obligations hereunder.

121

(b) No successor indenture trustee shall accept appointment as provided in this Section 11.08 unless at the time of such acceptance such successor indenture trustee shall be eligible under the provisions of Section 11.06.

(c) Upon acceptance of appointment by a successor indenture trustee as provided in this Section 11.08, such successor indenture trustee shall mail notice of the succession of such the Indenture Trustee hereunder to the Issuers, the Servicer and the Noteholders.

SECTION 11.09. Merger or Consolidation of Indenture Trustee. Any entity into which the Indenture Trustee may be merged or converted or with which it may be consolidated or any entity resulting from any merger, conversion or consolidation to which the Indenture Trustee shall be a party, or any entity succeeding to the corporate trust business of the Indenture Trustee shall be the successor of the Indenture Trustee hereunder, provided, such entity shall be eligible under the provisions of Section 11.06, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 11.10. Appointment of Co-Indenture Trustee or Separate Indenture Trustee. (a) Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any of the Notes or property securing the same may at the time be located, the Indenture Trustee shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Indenture Trustee to act as co-indenture trustee or co-indenture trustees, jointly with the Indenture Trustee, or separate indenture trustee or separate indenture trustees, of the Notes, and to vest in such Person or Persons, in such capacity, such title to the Notes, or any part thereof, and, subject to the other provisions of this Section 11.10, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No co-indenture trustee or separate indenture trustee hereunder shall be required to meet the terms of eligibility as a successor indenture trustee under Section 11.06, and no notice to holders of Notes of the appointment of co-indenture trustee(s) or separate indenture trustee(s) shall be required under Section 11.08.

(b) In the case of any appointment of a co-indenture trustee or separate indenture trustee pursuant to this Section 11.10, all rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and exercised or performed by the Indenture Trustee and such separate indenture trustee or co-indenture trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Indenture Trustee hereunder or when acting as successor servicer under the Servicing Agreement), the Indenture Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed by such separate indenture trustee or co-indenture trustee solely at the direction of the Indenture Trustee.

122

(c) Any notice, request or other writing given to the Indenture Trustee shall be deemed to have been given to each of the then separate indenture trustees and co-indenture trustees, as effectively as if given to each of them. Every instrument appointing any separate indenture trustee or co-indenture trustee shall refer to this Indenture and the conditions of this Article XI. Each separate indenture trustee and co-indenture trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be provided therein, subject to all of the provisions of this Indenture and any Indenture Supplement, specifically including every provision of this Indenture and any Indenture Supplement relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Every such instrument shall be filed with the Indenture Trustee.

The Indenture Trustee shall not be responsible for any act or inaction of any such trustee or co-trustee. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

(e) The appointment of a co-trustee or separate trustee under this Section 11.10 shall not relieve the Indenture Trustee of its duties and responsibilities hereunder.

SECTION 11.11. Access to Certain Information. (a) The Indenture Trustee shall afford to the Issuers, the Initial Purchasers, the Servicer, the Controlling Holders Representative and each Rating Agency and any banking or insurance regulatory authority that may exercise authority over any Noteholder or Note Owner, access to any documentation regarding the Notes. Such access shall be afforded without charge but only upon reasonable prior written request and during normal business hours at the Corporate Trust Office of the Indenture Trustee.

(b) The Indenture Trustee shall maintain at its Corporate Trust Office and, upon reasonable prior written request and during normal business hours, shall make available, or cause to be made available, for review by the Issuers, the Rating Agencies, and the Controlling Holders Representative originals and/or copies of the following items (to the extent that such items were prepared by or delivered to the Indenture Trustee): (i) the Offering Memorandum and any other disclosure document relating to the Notes, in the form most recently provided to the Indenture Trustee by the Issuers or by any Person designated by the Issuers; (ii) this Indenture, and any applicable Indenture Supplements and any amendments and exhibits hereto or thereto; (iii) the Servicing Agreement, each sub-servicing agreement delivered to the Indenture Trustee since the Closing Date and any amendments and exhibits or thereto; (iv) all Indenture Trustee Reports actually delivered or otherwise made available to Noteholders pursuant to Section 11.11(d) since the Closing Date; and (v) any other information in the possession of the Indenture Trustee that may be

The Indenture Trustee shall provide, or cause to be provided, or make available copies of any and all of the foregoing items to any of the Persons set forth in the previous sentence promptly following request therefor by such Person; provided, however, that except in the case of the Rating Agencies, the Indenture Trustee shall be permitted to require payment of a sum sufficient to cover the reasonable costs and expenses of providing such copies.

(c) Upon reasonable advance notice and at the expense of any Noteholder, Note Owner or Person identified to the Indenture Trustee as a prospective transferee of a Note or an interest therein (a “Requesting Party”), the Indenture Trustee, subject to the succeeding paragraph, shall make available to such Requesting Party copies of (i) the form of Indenture; (ii) the form of Management Agreement; (iii) the Offering Memorandum as amended or supplemented from time to time; (iv) this Indenture and any Indenture Supplement, as amended from time to time; (v) all Indenture Trustee Reports; and (vi) the most recent audited consolidated Financial Statements of the Issuer Parties and Crown International; provided that the Requesting Party furnish to the Indenture Trustee a written certification substantially in the form attached hereto as Exhibit E as to the effect that (x) in the case of a Noteholder, such Person shall keep such information confidential (except that any Noteholder may provide any such information obtained by it to any other Person that holds or is contemplating the purchase of any Note or interest therein, provided that such other Person confirms to such Noteholder in writing such ownership interest or prospective ownership interest and agrees to keep such information confidential); (y) in the case of a Note Owner, such Person is a Beneficial Owner of Notes held in book-entry form and shall keep such information confidential (except that such Note Owner may provide such information to any other Person that holds or is contemplating the purchase of any Note or interest therein, provided that such other Person confirms to such Note Owner in writing such ownership interest or prospective ownership interest and agrees to keep such information confidential) and (z) in the case of a Person identified to the Indenture Trustee as a prospective transferee of a Note or an interest therein, such Person is a bona fide prospective purchaser of a Note or an interest therein, is requesting the information for use in evaluating a possible investment in Notes and shall otherwise keep such information confidential.

(d) Based solely on information provided in the Servicer’s monthly reports (based solely on information provided by the Manager) and delivered to the Indenture Trustee, the Indenture Trustee shall prepare and make available on each Payment Date to each Noteholder such report (collectively, an “Indenture Trustee Report”) and shall also make available an electronic file detailing information regarding the performance of the Tower Sites to the extent such information is delivered to the Indenture Trustee by the Servicer. Until such time as Definitive Notes are issued in respect of the Book-Entry Notes, the foregoing information shall be available to the Note Owners only to the extent that it can be obtained through DTC and the DTC Participants. However, any Note Owner that does not receive information through DTC or a DTC Participant may obtain such information from

124

the Indenture Trustee’s website; provided that the Note Owner furnish to the Indenture Trustee a written certification in the form attached hereto as Exhibit E to the effect that such Person is a Beneficial Owner of the Notes held in book-entry form and shall keep such information confidential. The manner in which notices and other communications are conveyed by DTC to DTC Participants, and by DTC Participants to the Note Owners, shall be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. The Servicer and the Indenture Trustee are required to recognize as Noteholders only those persons in whose names the Notes are registered on the books and records of the Note Registrar.

(e) Neither the Indenture Trustee nor the Servicer shall be liable for providing or disseminating the Indenture Trustee Report or other information to the extent in accordance with the terms of this Indenture.

Promptly after the execution by the Issuers and the Indenture Trustee of any indenture supplement pursuant to this Section 13.02, the Indenture Trustee shall mail to the Holders of the Notes and the Servicer a copy of such indenture supplement.

(c) All sums payable under this Guaranty shall be payable within five (5) days after demand therefor and without reduction for any offset, claim, counterclaim or defense.

SECTION 15.02. Unconditional Character of Obligations of Guarantor. (a) The obligations of Guarantor hereunder shall be irrevocable, absolute and unconditional, irrespective of the validity, regularity or enforceability, in whole or in part, of the Notes, the Indenture or the other Transaction Documents or any provision thereof, or the absence of any action to enforce the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any Issuer, Guarantor or any other Person or any action to enforce the same, any failure or delay in the enforcement of the obligations of the Issuers under the Notes, the Indenture or any other Transaction Documents or Guarantor under this Guaranty or the Pledge Agreement, or any setoff, counterclaim, and irrespective of any other circumstances which might otherwise limit recourse against Guarantor by the Indenture Trustee or constitute a legal or equitable discharge or defense of a guarantor or surety. The Indenture Trustee may enforce the obligations of Guarantor under this Guaranty by a proceeding at law, in equity or otherwise, independent of any foreclosure or similar proceeding under the Notes or any deficiency action against the Issuers or any other Person at any time, either before or after an action against the Issuer or any other Person. This Guaranty is a guaranty of payment and performance and not merely a guaranty of collection. Guarantor

130

waives diligence, notice of acceptance of this Guaranty, filing of claims with any court, any proceeding to enforce any provision of the Notes, the Indenture or any other Transaction Documents, against Guarantor, the Issuers or any other Person, any right to require a proceeding first against the Issuers or any other Person, or to exhaust any security for the performance of the Guaranteed Obligations or any other obligations of the Issuers or any other Person, or any protest, presentment, notice of default (except as may be expressly required under the Transaction Documents) or other notice or demand whatsoever, and Guarantor hereby covenants and agrees that it shall not be discharged of its obligations hereunder.

(b) The obligations of Guarantor under this Guaranty, and the rights of the Indenture Trustee to enforce the same by proceedings, whether by action at law, suit in equity or otherwise, shall not be in any way affected by any of the following:

(i) any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, receivership, conservatorship, winding up or other similar proceeding involving or affecting the Issuers, the Manager, the Collateral or any part thereof, Guarantor or any other Person;

(ii) any failure by the Indenture Trustee or any other Person, whether or not without fault on its part, to perform or comply with any of the terms of the Indenture, or any other Transaction Documents, or any document or instrument relating thereto;

(iii) the sale, transfer or conveyance of any Collateral or any interest therein to any Person, whether now or hereafter having or acquiring an interest in any Collateral;

(iv) the release of any Issuer or any other Person from the performance or observance of any of the agreements, covenants, terms or conditions contained in any of the Transaction Documents by operation of law or otherwise; or

(v) the release in whole or in part of any Collateral for any or all Guaranteed Obligations or for the Notes or any portion thereof.

(c) Except as otherwise specifically provided in this Guaranty, Guarantor hereby expressly and irrevocably waives all defenses in an action brought by the Indenture Trustee to enforce this Guaranty based on claims of waiver, release, surrender, alteration or compromise and all setoffs, reductions, or impairments, whether arising hereunder or otherwise.

(d) The Indenture Trustee may deal with the Issuers and Affiliates of the Issuers as freely as if this Guaranty did not exist and shall be entitled, among other things, to grant the Issuers or any other Person such extension or extensions of time to perform any act or acts as may be deemed advisable by the Indenture Trustee, at any time and from time to time, without terminating, affecting or impairing the validity of this Guaranty or the obligations of Guarantor hereunder.

131

(e) No compromise, alteration, amendment, modification, extension, renewal, release or other change of, or waiver, consent, delay, omission, failure to act or other action with respect to, any liability or obligation under or with respect to, or of any of the terms, covenants or conditions of, the Note, the Indenture or the other Transaction Documents or any amendment, modification or other change of any legal requirement, shall in any way alter, impair or affect any of the obligations of Guarantor hereunder, and Guarantor agrees that if any Transaction Documents are modified with the Indenture Trustee’s consent, the Guaranteed Obligations shall automatically be deemed modified to include such modifications.

(f) The Indenture Trustee may proceed to protect and enforce any or all of its rights under this Guaranty by suit in equity or action at law, whether for the specific performance of any covenants or agreements contained in this Guaranty or otherwise, or to take any action authorized or permitted under applicable law, and shall be entitled to require and enforce the performance of all acts and things required to be performed hereunder by Guarantor. Each and every remedy of the Indenture Trustee shall, to the extent permitted by law, be cumulative and shall be in addition to any other remedy given hereunder or now or hereafter existing at law or in equity.

(g) No waiver shall be deemed to have been made by the Indenture Trustee of any rights hereunder unless the same shall be in writing and signed by the Indenture Trustee, and any such waiver shall be a waiver only with respect to the specific matter involved and shall in no way impair the rights of the Indenture Trustee or the obligations of Guarantor to the Indenture Trustee in any other respect or at any other time.

(h) At the option of the Indenture Trustee, Guarantor may be joined in any action or proceeding commenced by the Indenture Trustee against the Issuers in connection with or based upon the Note, the Indenture or any other Transaction Documents and recovery may be had against Guarantor in such action or proceeding or in any independent action or proceeding against Guarantor to the extent of Guarantor’s liability hereunder, without any requirement that the Indenture Trustee first assert, prosecute or exhaust any remedy or claim against the Issuers or any other Person, or any security for the obligations of the Issuers or any other Person.

(i) Guarantor agrees that this Guaranty shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment is made by the Issuers or Guarantor to the Indenture Trustee and such payment is rescinded or must otherwise be returned by the Indenture Trustee (as determined by the Indenture Trustee in its sole and absolute discretion) upon insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, receivership, conservatorship, winding up or other similar proceeding involving or affecting any Issuer or Guarantor, all as though such payment had not been made.

132

(j) In the event that Guarantor shall advance or become obligated to pay any sums under this Guaranty or in connection with the Guaranteed Obligations or in the event that for any reason whatsoever any Issuer or any subsequent owner of the Collateral or any part thereof is now, or shall hereafter become, indebted to Guarantor, Guarantor agrees that (i) the amount of such sums and of such indebtedness and all interest thereon shall at all times be subordinate as to the Lien, the time of payment and in all other respects to all sums, including principal and interest and other amounts, at any time owed under the Indenture or other Transaction Documents, and (ii) Guarantor shall not be entitled to enforce or receive payment thereof until all principal, interest and other sums due pursuant to the Indenture or other Transaction Documents have been paid in full. Nothing herein contained is intended or shall be construed to give Guarantor any right of subrogation in or under the Transaction Documents or any right to participate in any way therein, or in the right, title or interest of the Indenture Trustee in or to any collateral for the Notes, notwithstanding any payments made by Guarantor under this Guaranty, until the actual and irrevocable receipt by the Indenture Trustee of payment in full of all principal, interest and other sums due with respect to the Notes or otherwise payable under the Indenture or other Transaction Documents. If any amount shall be paid to Guarantor on account of such subrogation rights at any time when any such sums due and owing to the Indenture Trustee or the Servicer shall not have been fully paid, such amount shall be paid by Guarantor to the Indenture Trustee or the Servicer, as applicable, for credit and application against such sums due and owing to the Indenture Trustee or the Servicer, as applicable. The foregoing shall not prohibit the Issuer from using the proceeds of the Notes for any permitted use under the Indenture, including, without limitation, the making of distributions to Guarantor.

(k) Guarantor’s obligations hereunder shall survive the exercise of any power of sale or similar proceeding involving any collateral for this Guaranty or the Notes and the exercise by the Indenture Trustee of any or all of its remedies pursuant to the Transaction Documents.

SECTION 15.03. Interest; Expenses. (a) If Guarantor fails to pay all or any sums due hereunder within five (5) days after demand therefor by the Indenture Trustee, the amount of such sums payable by Guarantor to the Indenture Trustee shall bear interest from the expiration of such five (5) day period until paid at the then lowest Note Rate in effect from time to time, and Guarantor shall be obligated to pay the same in addition to the Guaranteed Obligations.

(b) Guarantor hereby agrees to pay, in addition to the Guaranteed Obligations, all out-of-pocket costs, charges and expenses, including, without limitation, reasonable attorneys’ fees and disbursements, that may be incurred by the Indenture Trustee in enforcing the covenants, agreements, obligations and liabilities of Guarantor under this Guaranty.

SECTION 15.04. Other Guaranties; Singular and Plural; Joint and Several Liability. (a) The obligations of Guarantor hereunder are separate and distinct from, and in addition to, the obligations of Guarantor now or hereafter arising under the other guaranties pursuant to which Guarantor has guaranteed the payment and performance of certain other obligations of the Issuers described therein.

133

(b) If there is more than one entity comprising Guarantor, all references to Guarantor herein shall be to such Guarantor or any one or more of them. All obligations and liabilities of Guarantor hereunder are in addition to, not in lieu of and are independent of: (i) all obligations of the Issuers under any other Transaction Document, including the Notes and the Indenture; and (ii) any obligation of Guarantor under any other Transaction Document to which Guarantor is a party.

(d) If any of the Issuers acquires or creates another subsidiary after the date hereof, then such newly acquired or created subsidiary that was formed under the laws of the United States or any state thereof or the District of Columbia will guarantee the Notes as a Guarantor and execute a Indenture Supplement and deliver an Opinion of Counsel satisfactory to the Indenture Trustee and the Servicer within 30 Business Days of the date on which it was acquired or created and execute and/or deliver such documents, instruments, agreements, financing statements, and perform such acts as the Indenture Trustee and/or the Servicer at any time may reasonably request to evidence the inclusion of such subsidiaries in the Assets and Collateral securing or intended to secure the Obligations; provided that each such subsidiary (i) shall be a bankruptcy remote single purpose entity substantially similar to the Issuers and (ii) shall be subject to the covenants under this Indenture as and to the same extent as the Issuers.

SECTION 15.05. Successors and Assigns. This Guaranty shall be binding upon Guarantor, and Guarantor’s respective estate, heirs, personal representatives, successors and assigns, may not be assigned or delegated by Guarantor and shall inure to the benefit of the successor and assigns of the Indenture Trustee, the Noteholders and the other Secured Parties.

ARTICLE XVI

Miscellaneous

SECTION 16.01. Compliance Certificates and Opinions, etc. Upon any application or request by the Issuers to the Indenture Trustee or Servicer to take any action under any provision of this Indenture, any Indenture Supplement or any Transaction Document, the Issuers shall furnish to the Indenture Trustee and Servicer (i) an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Indenture, any Indenture Supplement, or any Transaction Document relating to the proposed action have been complied with, when reasonably requested by the Indenture Trustee or Servicer, (ii) an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, and (iii) if applicable, an

134

Independent Certificate from a firm of certified public accountants meeting the applicable requirements of this Section 16.01, except that, in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture, any Indenture Supplement or any Transaction Document, no additional certificate or opinion need be furnished.

Every certificate or opinion provided by or on behalf of the Issuers with respect to compliance with a condition or covenant provided for in this Indenture, or any Indenture Supplement or any other Transaction Document shall include:

(i) a statement that the Person making such certificate or opinion has read or has caused to be read such covenant or condition;

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

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

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

Nothing herein shall be deemed to require either the Indenture Trustee or the Servicer to confirm, represent or warrant the accuracy of (or to be liable or responsible for) any other Person’s information or report, including any communication from any Issuer, the Guarantor or the Manager. In connection with the performance of its obligations hereunder and under the other Transaction Documents, each of the Indenture Trustee and the Servicer shall be entitled to rely upon any written information or certification (without any obligation to investigate the accuracy or completeness of any information or certification set forth therein) or recommendation provided to it by the Manager, and neither the Indenture Trustee nor the Servicer shall have any liability with respect thereto.

SECTION 16.02. Form of Documents Delivered to Indenture Trustee. (a) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

(b) Any certificate or opinion of an Authorized Officer of the Issuers may be based, insofar as it relates to legal matters, upon a certificate or Opinion of Counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters

135

upon which such officer’s certificate or opinion is based are erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Issuers, stating that the information with respect to such factual matters is in the possession of the Issuers, unless such officer or officers of the Issuers or such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

(c) Where any Person is required to make, give or execute two or more applications, requests, comments, certificates, statements, opinions or other instruments under this Indenture, any Indenture Supplement or any other Transaction Document, they may, but need not, be consolidated and form one instrument.

(d) Whenever in this Indenture, any Indenture Supplement or any other Transaction Document, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuers shall deliver any document as a condition of the granting of such application, or as evidence of the Issuers’ compliance with any term hereof, in any Indenture Supplement or any other Transaction Document, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such certificate or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuers to have such application granted or to the sufficiency of such certificate or report. The foregoing shall not, however, be construed to affect the Indenture Trustee’s or Servicer’s right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Article XI.

SECTION 16.03. Acts of Noteholders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture or any Indenture Supplement to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by agents duly appointed in writing; and except as otherwise expressly provided in this Indenture or in any Indenture Supplement such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee and the Servicer, and, where it is hereby expressly required, to the Issuers. Such instrument or instruments (and the action embodied in this Indenture or in any Indenture Supplement and evidenced thereby) are sometimes referred to in this Indenture as the “Act” of the Noteholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture or any Indenture Supplement and (subject to Article XI) conclusive in favor of the Indenture Trustee, the Servicer and the Issuers, if made in the manner provided in this Section 16.03.

136

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner which the Indenture Trustee deems sufficient.

(c) The ownership, principal balance and serial numbers of the Notes, and the date of holding the same, shall be proved by the Note Register.

(d) If the Issuers shall solicit from Noteholders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuers may, at their option, fix in advance a record date for the determination of Noteholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuers shall have no obligation to do so. Any such record date shall be fixed at the Issuers’ discretion. If not set by the Issuers prior to the first solicitation of a Noteholder made by any Person in respect of any such matters referred to in the foregoing sentence, such record date shall be the date 30 days prior to such first solicitation of Noteholders. If such a record date is fixed, such request, demand, authorization, direction, notice, consent and waiver or other Act may be sought or given before or after the record date, but only the Noteholders of record at the close of business on such record date shall be deemed to be Noteholders for the purpose of determining whether Noteholders of the requisite proportion of the Notes Outstanding have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Notes Outstanding shall be computed as of such record date.

(e) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Indenture Trustee, the Servicer or the Issuers in reliance thereon, whether or not notation of such action is made upon such Note.

(f) Without limiting the foregoing, a Noteholder entitled hereunder or under any Indenture Supplement to take any action hereunder or thereunder with regard to any Note may do so with regard to all or any part of the principal balance of such Note or by one or more appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal balance of such Note.

SECTION 16.04. Notices; Copies of Notices and Other Information. (a) Any request, demand, authorization, direction, notice, consent, waiver or Act of Noteholders or other documents provided or permitted by this Indenture shall be in writing and if such request, demand, authorization, direction, notice, consent, waiver or Act of Noteholders is to be made upon, given or furnished to or filed with:

(i) the Indenture Trustee by any Noteholder or by the Issuers shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Indenture Trustee at its Corporate Trust Office; or

137

(ii) the Issuers by the Indenture Trustee, the Servicer, or by any Noteholder shall be sufficient for every purpose hereunder if in writing and mailed first-class, postage prepaid and by facsimile to the Issuer Entity addressed to: 1220 August Drive, Suite 500, Houston, Texas 77057 or at any other address previously furnished in writing to the Indenture Trustee and the Servicer by the Issuer Entity. The Issuers shall promptly transmit any notice received by them from the Noteholders to the Indenture Trustee and Servicer.

(b) Any notice to be given to the Indenture Trustee hereunder shall also be given to the Note Registrar and the Servicer in writing, personally delivered, faxed or mailed by certified mail and shall not be deemed given to the Indenture Trustee until also given to the Note Registrar and the Servicer; provided, however, that only one notice to the Indenture Trustee shall be necessary at any time that the Indenture Trustee is also the Note Registrar.

(c) Any notice, and copies of any reports, certificates, schedules, statements, documents or other information to be given to the Indenture Trustee by the Issuers or Crown International hereunder shall also be simultaneously given to the Servicer in writing, personally delivered, faxed or mailed by certified mail and shall not be deemed given to the Indenture Trustee until also given to the Servicer; provided, however, that only one notice or copy of such reports, certificates, schedules, or other information required to be given to the Indenture Trustee shall be necessary at any time that the Indenture Trustee is also the Servicer.

(d) Notices required to be given to the Rating Agencies by the Issuers or the Indenture Trustee shall be in writing, personally delivered, faxed or mailed by certified mail, to the following addresses: (i) Fitch, Inc., One State Street Plaza, New York, NY 10004, Attention: [•], (ii) Moody’s Investors Service, Inc., 7 World Trade Center, 250 Greenwich Street, New York, NY 10007, Attention: [•].

SECTION 16.05. Notices to Noteholders; Waiver. (a) Where this Indenture or any Indenture Supplement provides for notice to Noteholders of any event, such notice shall be sufficiently given (unless otherwise expressly provided in this Indenture or in any Indenture Supplement) if in writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at his address as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Noteholder shall affect the sufficiency of such notice with respect to other Noteholders, and any notice that is mailed in the manner provided in this Indenture shall conclusively be presumed to have been duly given.

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

138

(c) In case, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to Noteholders when such notice is required to be given pursuant to any provision of this Indenture or any Indenture Supplement, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

(d) Where this Indenture or any Indenture Supplement provides for notice to the Rating Agencies, failure to give such notice to the Rating Agencies shall not affect any other rights or obligations created hereunder or under any Indenture Supplement, and shall not under any circumstance constitute a Default or Event of Default.

SECTION 16.06. Payment and Notice Dates. All payments to be made and notices to be delivered pursuant to this Indenture, any Indenture Supplement or any other Transaction Document shall be made by the responsible party as of the dates set forth in this Indenture, in any Indenture Supplement or in any other Transaction Document.

SECTION 16.07. Effect of Headings and Table of Contents. The Article and Section headings in this Indenture or in any Indenture Supplement and the Table of Contents are for convenience only and shall not affect the construction hereof or thereof.

SECTION 16.08. Successors and Assigns. All covenants and agreements in this Indenture, any Indenture Supplement and the Notes by the Issuers and the Guarantor shall bind their successors and assigns, whether so expressed or not. All agreements of the Indenture Trustee in this Indenture and any Indenture Supplement shall bind its successors, co-trustees and agents.

SECTION 16.09. Severability. In case any provision in this Indenture or any Indenture Supplement or in the Notes of any Series 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 16.10. Benefits of Indenture. Subject to Section 13.01 and Section 13.02 and Article XI, nothing in this Indenture, any Indenture Supplement or in the Notes, express or implied, shall give to any Person, other than the parties hereto, the Servicer and their successors hereunder, the Noteholders and any other party secured hereunder or under any such Indenture Supplement, and any other Person with an ownership interest in any part of the Collateral and the Rating Agencies, any benefit or any legal or equitable right, remedy or claim under this Indenture or any Indenture Supplement.

139

SECTION 16.11. Legal Holiday. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any other provision of the Notes, this Indenture or any Indenture Supplement) payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and, except as otherwise expressly provided in this Indenture or in any such Indenture Supplement, no interest shall accrue for the period from and after any such nominal date.

SECTION 16.12. Governing Law. THIS INDENTURE AND EACH INDENTURE SUPPLEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO ANY OF ITS PRINCIPLES OF CONFLICTS OF LAWS WHICH WOULD INVOKE THE SUBSTANTIVE LAW OF A DIFFERENT JURISDICTION) AS TO ALL MATTERS, INCLUDING, WITHOUT LIMITATION, MATTERS OF VALIDITY, CONSTRUCTION, EFFECT, PERFORMANCE AND REMEDIES. THE ISSUERS IRREVOCABLY SUBMIT TO THE JURISDICTION OF ANY NEW YORK STATE COURT OR UNITED STATES FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR IN RELATION TO THIS INDENTURE OR EACH SUCH INDENTURE SUPPLEMENT.

SECTION 16.13. Counterparts. This Indenture and any Indenture Supplement may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such respective counterparts shall together constitute but one and the same instrument.

SECTION 16.14. Recording of Indenture. If this Indenture or any Indenture Supplement is subject to recording in any appropriate public recording offices, such recording is to be effected by the Issuers and at their expense.

SECTION 16.15. Corporate Obligation. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuers, the Guarantor or the Indenture Trustee, in each of their capacities hereunder or under any Indenture Supplement, on the Notes, under this Indenture or any Indenture Supplement or any certificate or other writing delivered in connection herewith, under any Indenture Supplement, against (i) the Indenture Trustee, the Paying Agent and the Note Registrar in its individual capacity, or (ii) any partner, owner, beneficiary, agent, officer, director, employee or agent of the Indenture Trustee in its individual capacity, any holder of equity in the Issuers, the Guarantor or the Indenture Trustee or in any successor or assign of the Indenture Trustee in its individual capacity, except as any such Person may have expressly agreed (it being understood that the Indenture Trustee has no such obligations in its individual capacity), and except that any such partner, owner or equity holder shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity.

SECTION 16.16. No Petition. The Indenture Trustee, by entering into this Indenture or any Indenture Supplement, and each Noteholder, by accepting a Note, and each Note Owner, by accepting an ownership interest in a Global Note, hereby

140

covenants and agrees that neither it nor the Indenture Trustee on behalf of such Noteholder shall at any time institute against the Issuers or the Guarantor, or join in any institution against the Issuers or the Guarantor of, any bankruptcy, reorganization, insolvency or similar proceedings, or other proceedings under any Federal, state or foreign bankruptcy or similar law in connection with any obligations relating to the Notes, this Indenture, any such Indenture Supplement or any of the Transaction Documents.

SECTION 16.17. Extinguishment of Obligations. Notwithstanding anything to the contrary in this Indenture or any Indenture Supplement, all obligations of the Issuers and the Guarantor hereunder or under any Indenture Supplement shall be deemed to be extinguished in the event that, at any time, the Issuers and the Guarantor have no assets (which shall include claims that may be asserted by the Issuers and the Guarantor with respect to contractual obligations of third parties to the Issuers and the Guarantor). No further claims may be brought against any of the Issuers’ directors or officers or against their shareholders or members, as the case may be, for any such obligations, except in the case of fraud or actions taken in bad faith by such Persons.

SECTION 16.18. Inspection. The Issuers agree that, with reasonable prior notice, the Issuers shall permit any representative of the Indenture Trustee or the Servicer, during the Issuers’ normal business hours, to examine all the books of account, records, reports and other papers of the Issuers, to make copies and extracts therefrom, to cause such books to be audited by independent certified public accountants (only at one or more locations outside of the United States), and that the Issuers shall discuss their affairs, finances and accounts with their officers, employees, and independent certified public accountants, all at such reasonable times and as often as may be reasonably requested.

SECTION 16.19. [Reserved].

SECTION 16.20. Waiver of Immunities. To the extent that the Issuers have or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to themselves or their property, the Issuers hereby irrevocably waive such immunity in respect of their obligations under this Indenture, any Indenture Supplement, the Notes and any other Transaction Document, to the extent permitted by law.

SECTION 16.21. Non-Recourse. The Noteholders shall not have at any time any recourse on the Notes or under this Indenture or any Indenture Supplement against the Issuers (other than the Collateral) or against the Indenture Trustee, the Servicer or any agents or Affiliates thereof (but not the Guarantor, which shall remain fully liable under the Guaranty).

SECTION 16.22. Indenture Trustee’s Duties and Obligations Limited. The duties and obligations of the Indenture Trustee, in its various capacities hereunder and under any Indenture Supplement, shall be limited to those expressly provided for in

141

their entirety in this Indenture (including any exhibits to this Indenture and to any Indenture Supplement). Any references in this Indenture and in any Indenture Supplement (and in the exhibits to this Indenture and to any Indenture Supplement) to duties or obligations of the Indenture Trustee, in its various capacities hereunder and under any such Indenture Supplement, that purport to arise pursuant to the provisions of any of the Transaction Documents or any such Indenture Supplement shall only be duties and obligations of the Indenture Trustee, or the Indenture Trustee in its other capacities, as applicable, if the Indenture Trustee is a signatory to any such Transaction Documents or any such Indenture Supplement. By its acquisition of the Notes, each Noteholder shall be deemed to have authorized and directed the Indenture Trustee to enter into the Transaction Documents to which the Indenture Trustee is a signatory.

SECTION 16.23. Appointment of Servicer. The Issuers hereby consent to the appointment of Midland Loan Services, Inc. to act as Servicer.

SECTION 16.24. Waiver of Trial Jury. EACH OF THE ISSUERS, THE GUARANTOR AND THE INDENTURE TRUSTEE IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.
