(a) The Issuer may, at its 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. Any Note Registrar appointed in accordance with this Section 2.02(a) may at any time resign by giving at least 30 days’ advance written notice of resignation to the Indenture Trustee, the Servicer and the Issuer. The Issuer 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.

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 Issuer, 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 will 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 B-5 or Exhibit B-6 and a certificate from the prospective Transferee substantially in the form attached hereto as Exhibit B-3 or Exhibit B-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 Issuer, 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 B-1, or (ii) an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Issuer, 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 B-1 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 Issuer 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 or 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 B-2 certifying that such Transferee is not a U.S. Person (as defined under Regulation S). 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 Issuer 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.

Neither the Issuer, the Indenture Trustee nor the Note Registrar shall be obligated to register or qualify any Class of Notes under the Securities Act or any other 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 does hereby agree to, indemnify the Obligors, 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 Plan or to any Person who is directly or indirectly purchasing or holding 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 by the prospective Transferee would result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation of any applicable Similar Laws. 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, except in each such case, in accordance with the following provisions of this Section 2.02(c). Any attempted or purported transfer of a Note in violation of this Section 2.02(c) will 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 will constitute a Definitive Note, unless it has received from the prospective Transferee a certification that either:

(i) such prospective Transferee is not a Plan and is not directly or indirectly purchasing or holding such interest in such Note on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan; or

(ii) such acquisition and holding by such Transferee of such Notes will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation of any applicable Similar Laws.

It is hereby acknowledged that either of the forms of certification attached hereto as Exhibits B-3 and B-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 will constitute a Definitive Note) shall obtain from its prospective Transferee a certification that either:

(i) such prospective Transferee is not a Plan and is not directly or indirectly acquiring or holding 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 B-1 and B-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 and Series 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 and Series 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 are 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 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.

(j) The Note Registrar shall provide to each of the other parties hereto, upon reasonable written request and at the expense of the requesting party, an updated copy of the Note Register.

Section 2.03 Book-Entry Notes.

(a) Each Class and Series 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), shall not be entitled to Definitive Notes in respect of such ownership interests. Notes of each Class and Series of Notes initially sold in reliance on Rule 144A shall be represented by the Rule 144A Global Note for such Class and Series, which shall be deposited with DTC Custodian for the Depositary and registered in the name of Cede & Co. as nominee of the Depositary. Notes of each Class and Series of Notes initially sold in offshore transactions in reliance on Regulation S shall be represented by the Regulation S Global Note for such Class and Series, 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 Issuer, 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 will thereafter be issued as Definitive Notes to applicable Note Owners or their nominees, rather than to DTC or its nominee, only (i) if the Issuer advises 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 Issuer is 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 will 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 and Series 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) and Series 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 Issuer, 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 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 the 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 of like Note Principal Balance 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 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.

Section 2.05 Persons Deemed Owners. Prior to due presentment for registration of transfer, the Issuer, 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 for the purpose of receiving payments pursuant to Article V and for all other purposes whatsoever, and neither the Issuer, the Servicer, 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, 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 Notes Issuable in Series.

The Notes of the Issuer may be issued in one or more Series. There shall be established in one or more Series Supplements, prior to the issuance of Notes of any Series:

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

(ii) any limit upon the aggregate principal balance of the Notes 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 Series pursuant to Section 2.04 or 2.06);

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

(iv) the rate or rates at which the Notes 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 (in each to the extent such items are not specified herein or if specified herein to the extent such items are modified by such Series Supplement); and

(v) any other terms of such Series (which terms shall not be inconsistent with the provisions of this Indenture except to the extent that such Series Supplement also constitutes an amendment of this Indenture pursuant to Article XIII).

The Notes of a Series may have more than one settlement or issue date. The Notes of each Series will be assigned to one or more Classes and shall satisfy the requirements of Section 2.12(b) as of the date of issuance.

Section 2.08 Principal Amortization. Prior to the Anticipated Repayment Date for a Series, unless an Amortization Period commences or as otherwise provided in Section 7.06, no principal shall be required to be paid with respect to such Series. During an Amortization Period or after an Event of Default, all Excess Cash Flow shall be applied as set forth in Section 5.01(b).

Section 2.09 Prepayments.

(a) The Issuer may not optionally prepay the Notes in whole or in part except as expressly set forth in this Indenture. Prior to the end of the Prepayment Lockout Period of a Series, the Issuer may not prepay the Notes of such Series in whole or in part unless such prepayment on the Notes of such Series is (A) made on any Payment Date (i) in order to cure a breach of a representation or warranty or other default with respect to a particular Tower Site or (ii) in accordance with Section 7.06, in connection with the casualty and condemnation events with respect to a Tower Site described in such Section and (B) accompanied by the applicable Prepayment Consideration. From and after the end of the Prepayment Lockout Period of a Series, the Issuer may optionally prepay the Notes of such Series in whole or in part; provided that such prepayment is accompanied by the applicable Prepayment Consideration if such prepayment occurs more than six (6) months prior to the Anticipated Repayment Date of such Series and, if such prepayment occurs on any day other than a Payment Date, is accompanied by payment of interest that would have accrued on the amount prepaid through the last day of the then current Interest Accrual Period.

(b) In connection with each disposition of a Tower Site as contemplated in Section 7.31, the Issuer shall prepay the Notes in an amount equal to the Release Price for such disposed Tower Site (and pay the current obligations of the Indenture Trustee and the Servicer, along with the Indenture Trustee Fee, Servicing Fee and Other Servicing Fees, in each case to the extent sufficient funds have not been deposited in the Collection Account for distribution on the applicable Payment Date) together with the applicable Prepayment Consideration if such prepayment of any Class of Notes of a Series occurs more than six (6) months prior to the Anticipated Repayment Date for such Series. Any funds remaining in the Liquidated Tower Replacement Account that are required to be applied to prepay the Notes shall be applied, first, to pay the Servicer and the Indenture Trustee all amounts then due to each of them hereunder and 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), and second, to prepay the Notes with the applicable Prepayment Consideration, if any.

(c) Partial optional or mandatory prepayments made in conformity with the provisions of this Section 2.09 will be applied to the Classes of all Notes of all Series in direct alphabetical order; provided that optional prepayments (other than those funded by application of amounts on deposit in the Cash Trap Reserve Sub-Account) may be directed by the Issuer to be applied to the Notes of a particular Series in such alphabetical order.

Section 2.10 Post-ARD Additional Interest. Additional interest (“Post-ARD Additional Interest”) shall begin to accrue with respect to a Note of a Series from and after the Anticipated Repayment Date for such Series on the Note Principal Balance thereof at a per annum rate (each, a “Post-ARD Additional Interest Rate”) equal to the rate determined by the Servicer to be the greater of (i) 5% per annum and (ii) the amount, if any, by which the sum of the following exceeds the Note Rate for such Note: (A) the yield to maturity (adjusted to a “mortgage equivalent basis” pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the Anticipated Repayment Date for such Note of the United States Treasury Security having a term closest to ten (10) years plus (B) 5%, plus (C) the Post-ARD Note Spread applicable to such Note. The Servicer shall provide written notice to the Indenture Trustee of the Post-ARD Additional Interest Rate. The Post-ARD Additional Interest accrued for any Class of Notes will not be payable until the aggregate Class Principal Balance of all Classes of Notes has been reduced to zero, and the Value Reduction Amount Interest Restoration Amount has been reduced to, or is equal to, zero, and until such time, the Post-ARD Additional Interest will be deferred and added to any Post-ARD Additional Interest previously deferred and remaining unpaid (the “Deferred Post-ARD Additional Interest”). Deferred Post-ARD Additional Interest will not bear interest.

Section 2.11 Defeasance.

(a) At any time prior to the Payment Date that is six (6) months prior to the Anticipated Repayment Date of any outstanding Series (such Payment Date, the “Defeasance Payment Date”) , the Issuer may obtain the release from all covenants of this Indenture relating to ownership and operation of the Tower Sites by delivering United States government securities that provide for payments which replicate the required payments on all of the Notes then outstanding and the Indenture Trustee Fee and Workout Fees, if any, through the Defeasance Payment Date for each Series of Notes (including payment in full of the principal of the Notes on the related Defeasance Payment Date); provided, that (i) no Event of Default has occurred and is continuing and (ii) the Issuer shall pay or deliver on the date of such defeasance (the “Defeasance Date”) (a) all interest accrued and unpaid on the Outstanding Class Principal Balance of each Class of Notes to but not including the Defeasance Date (and if the Defeasance Date is not a Payment Date, the interest that would have accrued to but not including the next Payment Date), (b) all other sums then due under each Class of Notes and all other Transaction Documents executed in connection therewith, including any costs incurred in connection with such defeasance, and (c) U.S. government securities providing for payments equal to the Scheduled Defeasance Payments. In addition, the Issuer shall deliver to the Servicer on behalf of the Indenture Trustee (1) a security agreement granting the Indenture Trustee a first priority perfected security interest on the U.S. government securities so delivered by the Issuer, (2) an Opinion of Counsel as to the enforceability and perfection of such security interest, (3) a confirmation by an Independent certified public accounting firm that the U.S. government securities so delivered are sufficient to pay all interest due from time to time after the Defeasance

Date (or if the Defeasance Date is not a Payment Date, due after the next Payment Date) and all principal due upon maturity for each Class of Notes, and all Indenture Trustee Fee and Workout Fees, if any, and (4) a Rating Agency Confirmation. The Issuer, pursuant to the security agreement described above, shall authorize and direct that the payments received from the U.S. government securities shall be made directly to the Indenture Trustee and applied to satisfy the obligations of the Issuer under the Notes and the other Transaction Documents.

(b) If the Asset Entities will continue to own any material assets other than the U.S. government securities delivered in connection with the defeasance, the Issuer shall establish or designate a special-purpose bankruptcy-remote successor entity acceptable to the Indenture Trustee, with respect to which (i) a substantive non-consolidation Opinion of Counsel reasonably satisfactory to the Indenture Trustee has been delivered to the Indenture Trustee and to transfer to that entity the pledged U.S. government securities and (ii) an Opinion of Counsel reasonably satisfactory to the Indenture Trustee has been delivered to the Indenture Trustee that the Issuer will not be required to register as an investment company under the Investment Company Act. The new entity shall assume the obligations of the Issuer under the Notes being defeased and the security agreement and the Obligors and the Guarantor shall be relieved of their obligations in respect thereof under the Transaction Documents. The Issuer shall pay Ten Dollars ($10) to such new entity as consideration for assuming such obligations.

Section 2.12 New Tower Sites; Additional Notes.

After repayment of all of the Obligations, all funds held as Reserves will be promptly returned to, or as directed by, the Issuer.

(b) Funding at Closing. The Issuer 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 Initial Closing Date (or on any subsequent Closing Date) may occur by deduction from the amount of proceeds of the issuance of the Notes on such Closing Date that otherwise would be disbursed to the Issuer, followed by deposit of the same into the applicable Sub-Account or Accounts of the Collection Account in accordance with the Cash Management Agreement on such Closing Date.

If at any time the Servicer (solely in reliance upon a written request received from the Manager) reasonably determines that the amount in the Impositions and Insurance Reserve Sub-Account will not be sufficient to pay the Impositions and Insurance Premiums when due, the Indenture Trustee shall (at the direction of the Servicer) increase the monthly deposits by the amount that the Servicer has determined (in reliance on the Manager’s written request) is sufficient to make up the deficiency and, in such instance, the Issuer shall deposit with the Collection Account Bank within ten (10) Business Days of a written demand by the Indenture Trustee, for credit to the Impositions and Insurance Reserve Sub-Account, a sum of money which the Servicer has determined (in reliance on the Manager’s written request), together with such monthly deposits, will 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 Asset Entities and the Tower Sites) at least ten (10) Business Days prior to the date initially due. The Asset Entities will 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 (5) 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 Obligors 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 the Imposition and Insurance Premiums directly, (y) disburse to the Obligors from such Reserve an amount sufficient to pay the Imposition and Insurance Premiums or (z) reimburse the Obligors for items previously paid by the Obligors.

Pursuant to this Indenture and the Cash Management Agreement, the Indenture Trustee shall deposit into a Sub-Account (the “Expense Reserve Sub-Account”) from Collections available for such purpose under Article V on each Business Day during each Collection Period, an amount such that the amount on deposit in the Expense Reserve Sub-Account as of the last day of such Collection Period will equal the amount of the Servicing Fee, the Indenture Trustee Fee and Other Servicing Fees due on the Payment Date following the last day of such Collection Period (the “Expense Reserve”), as directed by the Servicer, and such Expense Reserve shall be held, allocated and disbursed in accordance with the terms and conditions of the Cash Management Agreement.

Section 4.06 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 Collections available for such purpose under Article V (except as otherwise expressly provided below) shall be deposited with the Indenture Trustee and held in a Sub-Account of the Collection 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”). On the first Payment Date to occur on or after the commencement of an Amortization Period, or on any Payment Date at the direction of the Issuer, the Indenture Trustee will apply all funds on deposit in the Cash Trap Reserve Sub-Account to reimbursement of the Indenture Trustee and the Servicer 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), and the remaining amount thereof shall be deposited in the Debt Service Sub-Account and applied to payment of the Notes on such Payment Date (including any required Yield Maintenance) in accordance with Section 5.01(b).

This Indenture is, and each of the other Transaction Documents to which such Obligor is a party, when executed and delivered by such Obligor will be, the legally valid and binding obligation of such Obligor, enforceable against it, in accordance with its respective terms, subject to bankruptcy, insolvency, moratorium, reorganization and other similar laws affecting creditor’s rights.

Section 6.03 Financial Statements. All Financial Statements which have been furnished by or on behalf of the Obligors to the Indenture Trustee pursuant to this Indenture present fairly in all material respects the financial condition of the Persons covered thereby.

Section 6.04 Indebtedness and Contingent Obligations. As of the Closing Date, the Obligors shall have no outstanding Indebtedness or Contingent Obligations other than the Obligations and other Permitted Indebtedness.

Section 6.05 Title to the Tower Sites; Perfection and Priority. Each of the Asset Entities has good and marketable fee simple title (or, in the case of the Ground Lease Sites, leasehold title) to the Tower Sites purported to be owned in fee or leased under Ground Leases by it, free and clear of all Liens except for Permitted Encumbrances. Each of the Asset Entities owns all personal property on its Tower Sites (other than the Managed Sites and personal property which is owned by tenants of such Tower Site or is leased by the Asset Entities as permitted hereunder), subject only to Permitted Encumbrances. The Deeds of Trust will create (i) a valid, perfected first lien on the real property interests of the Asset Entities in and to the Mortgaged Sites and (ii) perfected first priority security interests in and to, and perfected collateral assignments of, all personalty in connection therewith (including the Rents and the Tenant Leases), in each case to the extent that such liens and security interests may be perfected by filing or recording such Deed of Trust or a financing statement under the UCC, in each case subject only to Permitted Encumbrances. Except as set forth on Schedule 6.05, (i) there are no proceedings in condemnation or eminent domain affecting any of the Tower Sites, and to the actual Knowledge of the Asset Entities, none is threatened; (ii) no Person has any option or other right to purchase all or any portion of any interest owned by the Asset Entities with respect to the Tower Sites; and (iii) there are no mechanic’s, materialman’s or other similar liens or claims which have been filed for work, labor or materials affecting the Tower Sites which are or will be liens prior to, or equal or coordinate with, the lien of the applicable Deed of Trust the effect of which is reasonably likely to have a Material Adverse Effect. The Permitted Encumbrances, in the aggregate, do not materially interfere with the benefits of the security intended to be provided by the Deeds of Trust and this Indenture, materially and adversely affect the value of the Tower Sites taken as a whole, impair the use or operations of the Tower Sites or impair the Obligors’ 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, except to the extent failure to so comply would not, in the aggregate, be reasonably likely to have a Material Adverse Effect. To the Obligors’ Knowledge, all permits, licenses and certificates for the lawful use, occupancy and operation of each component of each of the Tower Sites 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 or maintain any such permits, licenses or certificates would not, in the aggregate, be reasonably likely to have a Material Adverse Effect. To the Obligors’ Knowledge, no legal proceedings are pending or threatened with respect to the zoning of any Tower Site except to the extent the same would not, in the aggregate, be reasonably likely to have a Material Adverse Effect.

Section 6.07 Tenant Leases; Agreements.

The Obligors have made available, and will deliver upon request, to the Indenture Trustee (i) true and complete copies (in all material respects) of all Material Tenant Leases or, in the case of Tenant Leases not included in such Material Tenant Leases, Master Lease Agreements accompanied by a form of Tenant Lease and a summary of encompassed Tenant Leases and (ii) a list of all Material Agreements affecting the operation and management of the Tower Sites, and such Tenant Leases and list of Material Agreements have not been modified or amended except pursuant to amendments or modifications delivered to the Indenture Trustee. Except for the rights of the Manager pursuant to the Management Agreement, and the fee owners of Managed Sites, no Person has any right or obligation to manage any of the Tower Sites on behalf of the Asset Entities or to receive compensation in connection with such management. Except for the parties to any leasing brokerage agreement that has been delivered to the Indenture Trustee, no Person has any right or obligation to lease or solicit tenants for the Tower Sites, or (except for cooperating outside brokers) to receive compensation in connection with such leasing.

(b) Rent Roll, Disclosure. A true and correct copy of the Rent Roll has been delivered to Indenture Trustee. Except as specified in the Rent Roll, or as otherwise disclosed to the Indenture Trustee in the estoppel certificates delivered to Indenture Trustee on or before the Closing Date, to the Issuer’s and the Asset Entities’ Knowledge, (i) the Tenant Leases are in full force and effect; (ii) the Asset Entities have not given any notice of default to any Tenant under any Tenant Lease which remains uncured; (iii) no Tenant has any set off, claim or defense to the enforcement of any Tenant Lease; (iv) no Tenant is materially in default in the performance of any other obligation under its Tenant Lease; and (v) there are no rent concessions (whether in form of cash contributions, work agreements, assumption of an existing Tenant’s other obligations, or otherwise) or extensions of time whatsoever not reflected in such Rent Roll, except to the extent that the failure of the representations set forth in items (i) through (iv) to be true with respect to Tenant Leases (other than Material Tenant Leases) is not reasonably likely to have a Material Adverse Effect. To the Obligors’ Knowledge, each of the Tenant Leases is valid and binding on the parties thereto in accordance with its terms.

(c) Management Agreement. The Issuer has delivered to the Indenture Trustee a true and complete copy of the Management Agreement as in effect on the Closing Date, and such Management Agreement has not been modified or amended except pursuant to amendments or modifications delivered to the Indenture Trustee. The Management Agreement is in full force and effect and no default by any of the parties thereto exists thereunder.

Section 6.08 Litigation; Adverse Facts. There are no judgments outstanding against the Obligors, or affecting any of the Tower Sites or any property of the Obligors, nor to the Obligors’ Knowledge is there any action, charge, claim, demand, suit, proceeding, petition,

governmental investigation or arbitration now pending or threatened against the Obligors, respectively, or any of the Tower Sites that could reasonably be expected to result in a Material Adverse Effect.

Section 6.09 Payment of Taxes. All material federal, state and local tax returns and reports of the Issuer and each Asset Entity 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 6.10 Performance of Agreements. To the Issuer’s Knowledge, neither the Issuer nor the Asset Entities are in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in any Contractual Obligation of any such Persons 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 6.11 Governmental Regulation. The Obligors are not subject to regulation under the Federal Power Act or the Investment Company Act.

Section 6.12 Employee Benefit Plans. Except as set forth on Schedule 6.12, the Obligors do not maintain or contribute to, or have any obligation under, any Employee Benefit Plans which could reasonably be expected to result in a Material Adverse Effect.

Section 6.13 Solvency. The Obligors (a) have not entered into any Transaction Document with the actual intent to hinder, delay, or defraud any creditor and (b) 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 Obligors’ assets taken as a whole exceed and will, immediately following the issuance of any Notes, exceed the Obligors’ total liabilities, including, without limitation, subordinated, unliquidated, disputed and Contingent Obligations. The fair saleable value of the Obligors’ assets taken as a whole is and will, immediately following the issuance of any Notes, be greater than the Obligors’ probable liabilities, including the maximum amount of its Contingent Obligations on its debts as such debts become absolute and matured. The Obligors’ assets taken as a whole do not and, immediately following the issuance of any Notes will not, constitute unreasonably small capital to carry out its business as conducted or as proposed to be conducted. The Obligors do not intend to, and do not believe that they will, 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 Obligors and the amounts to be payable on or in respect of obligations of the Obligors).

Section 6.14 Use of Proceeds and Margin Security. No portion of the proceeds from the issuance of the Notes shall be used by the Issuer or any Person in any manner that might cause the borrowing or the application of such proceeds to violate Regulation T, Regulation U or Regulation X or any other regulation of the Board of Governors of the Federal Reserve System.

Section 6.15 Insurance. Set forth on Schedule 6.15 is a description of all policies of insurance for the Asset Entities that are in effect as of the Closing Date.

(f) If such Ground Lease is in respect of a Mortgaged Site, such Ground Lease or a memorandum thereof or other instrument sufficient to permit recording of a deed of trust or similar security instrument has been recorded and such Ground Lease (or the applicable Estoppel) permits the interest of the lessee to be encumbered by this Indenture.

(g) Except for the Permitted Encumbrances, the Asset Entity’s interest in such Ground Lease is not subject to any Liens superior to, or of equal priority with, this Indenture unless a non-disturbance agreement has been obtained from the applicable holder of such Lien.

(ix) All Insurance Policies shall be in content (including, without limitation, endorsements or exclusions, if any), form, and amounts, and issued by companies,

reasonably satisfactory to the Servicer from time to time and shall name the Indenture Trustee and its successors and assignees as their interests may appear as an “additional insured” for each of the policies under this Section 7.05 and shall (except for worker’s compensation insurance) contain a waiver of subrogation clause reasonably acceptable to the Servicer. All Insurance Policies under Sections 7.05(i), (iv), (vi), and (vii) with respect to the Mortgaged Tower Sites shall contain a Non-Contributory Standard mortgagee clause and a mortgagee’s Loss Payable Endorsement (Form 438 BFU NS), or their equivalents (such endorsements shall entitle the Indenture Trustee to collect any and all proceeds payable under all such insurance, with the insurance company waiving any claim or defense against the Indenture Trustee for premium payment, deductible, self-insured retention or claims reporting provisions). All Insurance Policies shall provide that the coverage shall not be modified without thirty (30) days’ advance written notice to the Indenture Trustee and the Servicer and shall provide that no claims shall be paid thereunder to a Person other than the Indenture Trustee without ten (10) days’ advance written notice to the Indenture Trustee and the Servicer. The Issuer may obtain any insurance required by this Section 7.05 through blanket policies; provided, however, that such blanket policies shall separately set forth the amount of insurance in force (together with applicable deductibles, and per occurrence limits) with respect to the Tower Sites (which shall not be reduced by reason of events occurring on property other than the Tower Sites) and shall afford all the protections to the Indenture Trustee as are required under this Section 7.05. Except as may be expressly provided above, all policies of insurance required hereunder shall contain no annual aggregate limit of liability, other than with respect to liability insurance. If a blanket policy is issued, a certified copy of said policy shall be furnished, together with a certificate indicating that the Indenture Trustee is an additional insured (and, if applicable, loss payee) under such policy in the designated amount. The Issuer will deliver duplicate originals of all Insurance Policies, premium prepaid for a period of one (1) year, to the Indenture Trustee, Servicer and, in case of Insurance Policies about to expire, the Issuer will deliver duplicate originals of replacement policies satisfying the requirements hereof to the Indenture Trustee and the Servicer prior to the date of expiration; provided, however, if such replacement policy is not yet available, the Issuer shall provide the Indenture Trustee and the Servicer with an insurance certificate executed by the insurer or its authorized agent evidencing that the insurance required hereunder is being maintained under such policy, which certificate shall be acceptable to the Indenture Trustee and the Servicer on an interim basis until the duplicate original of the policy is available. An insurance company shall not be satisfactory unless such insurance company (a) is licensed or authorized to issue insurance in the state where the applicable Tower Site is located and (b) has 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 Issuer shall obtain and deliver to the Servicer a Rating 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 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 by ▇▇▇▇▇’▇ (if applicable) set forth above and all carriers in such syndicate have a claims-paying ability rating by ▇▇▇▇▇’▇ of not less than “B2” (to the extent rated by ▇▇▇▇▇’▇). The Issuer shall furnish 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 Issuer concurrent in form or contributing in the event of loss with the Insurance Policies. Losses shall be payable to the Indenture Trustee notwithstanding (1) any act, failure to act or negligence of the Obligors or their agents or employees, the Indenture Trustee or any other insured party which might, absent such agreement, result in a forfeiture or all or part of such insurance payment, other than the willful 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. 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 furnished to it by the Issuer 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. The property insurance described in this Section 7.05 shall include “underground hazards” coverage; “time element” coverage by which the Indenture Trustee shall be assured payment of all amounts due under the Notes, this Indenture and the other Transaction Documents; “extra expense” (i.e., soft costs), clean-up, transit and ordinary payroll coverage; and “expediting expense” coverage to facilitate rapid repair or restoration of the Tower Sites. The Insurance Policies shall not contain any deductible in excess of $250,000.

Section 7.06 Operation and Maintenance of the Tower Sites; Casualty; Condemnation.

(a) The Issuer shall cause the Asset Entities to maintain or cause to be maintained in good repair, working order and condition all material property necessary for use in the business of each Asset Entity, including the applicable Tower Sites, and to make or cause to be made all appropriate repairs, renewals and replacements thereof except to the extent the failure to do so would not reasonably be expected to have a Material Adverse Effect. All work required or permitted under this Indenture shall be performed in a workmanlike manner and in compliance with all applicable laws except to the extent the failure to do so would not reasonably be expected to have a Material Adverse Effect.

(b) (i) In the event of casualty or loss at any of the Tower Sites, the Issuer shall give prompt written notice, and in any event within three (3) Business Days of obtaining Knowledge thereof, of any such casualty or loss exceeding $250,000, or which is not covered by insurance, 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 Issuer hereby authorizes and empowers the Servicer as attorney-in-fact for the Asset Entities (jointly with the Asset Entities 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 Impositions and Insurance Reserve Sub-Account pending the Asset Entities’ 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 7.06 shall require the Indenture Trustee or the Servicer to incur any expense or take any action hereunder. The Issuer further authorizes the Indenture Trustee, at the Servicer’s option and direction, with respect to proceeds in excess of $1,000,000 (a) to hold the balance of such proceeds to be made available to the Asset Entities for the cost of Restoration of any of the Tower Sites or (b) unless prohibited by Section 7.06(c), to apply such Insurance Proceeds to payment of the Obligations whether or not then due.

(ii) The Issuer shall promptly give the Indenture Trustee and the Servicer 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 to deliver to the Indenture Trustee and the Servicer copies of any and all material papers served in connection with such proceedings. Each of the Obligors hereby irrevocably appoints the Servicer as the attorney-in-fact for such Asset Entities (jointly with the Asset Entities 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 Impositions and Insurance Reserve Sub-Account pending the Asset Entities’ 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 Issuer shall cause the Asset Entities to cause the Condemnation Proceeds in excess of $1,000,000 which are payable to the Asset Entities 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 Asset Entities 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) the Asset Entities 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 (c) the Asset Entities promptly commence and diligently prosecute such reconstruction or repair to completion in accordance with all applicable laws. Subject to the terms hereof, each of the Asset Entities authorizes the Servicer and the Indenture Trustee to apply such Condemnation Proceeds, after the deduction of the Indenture Trustee and the Servicer’s reasonable expenses incurred in the collection of such Condemnation Proceeds, at the Servicer’s option and direction, to restoration or repair of the Tower Sites or to payment of the Obligations, whether or not then due. Application of any Condemnation Proceeds to payment of the Obligations pursuant to the foregoing sentence shall be made with the required Yield Maintenance. The Indenture Trustee shall not exercise the option to apply such Condemnation Proceeds to payment of the

Obligations; provided that 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) have been satisfied with respect to such condemnation awards or damages.

(c) The Indenture Trustee shall not exercise the Indenture Trustee’s 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 will be sufficient funds to complete the Restoration of the Tower Site to at least substantially the condition it was in immediately prior to such casualty (excluding replacement of obsolete Assets which are not required in connection with operating the applicable Tower Site) and in compliance with applicable laws (the “Pre-Existing Condition”) and to timely make all payments due under the Transaction Documents during the Restoration of the affected Tower Site; and (iii) the Servicer determines that the Restoration of the affected Tower Site to the Pre-Existing Condition will be completed not later than six (6) months prior to the latest Anticipated Repayment Date of any Notes then Outstanding. If the Servicer elects 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 Cash Management Agreement. Notwithstanding the foregoing to the contrary, the Issuer may, in its reasonable discretion, and within thirty (30) days of receipt of such Loss Proceeds, elect not to restore or replace a Tower Site, in which event all Loss Proceeds held in the Impositions and Insurance Reserve Sub-Account, after reimbursing any amounts due to the Servicer and the Indenture Trustee, shall be applied to payment of the Obligations on the Payment Date immediately following such election with the required Yield Maintenance in alphabetical order.

(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 Yield Maintenance and shall not extend or postpone the due dates of the monthly payments due under the Notes or otherwise under the Transaction Documents, or change the amounts of such payments. If the Servicer elects to apply all of such insurance or Condemnation Proceeds toward the repayment of the Obligations in accordance with Section 2.09, the Issuer shall be entitled to obtain from the Indenture Trustee a release (without representation or warranty) of the applicable Tower Site from the Lien of the Deed of Trust relating to such Tower Site (in which event the Issuer shall not be obligated to restore the applicable property pursuant to Section 7.06(b)). 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 Asset Entity 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 Issuer, 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 Asset Entities 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 will be paid in full out of the retainage.

Section 7.07 Inspection; Investigation. The Issuer shall permit, and shall cause each Asset Entity to 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 party’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 such Obligor’s 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 Obligor, 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 (3) Business Days prior to visiting or inspecting any Tower Site or such Obligor’s offices.

Section 7.08 Compliance with Laws and Obligations. The Issuer and the Asset Entities will (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 Obligor, 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 except to the extent the failure to so observe, comply or fulfill such could not reasonably be expected to have a Material Adverse Effect.

Section 7.09 Further Assurances. The Issuer shall and shall cause each Asset Entity to, 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. The Obligors shall file or cause to be filed all documents (including, without limitation, all financing statements) required to be filed by the terms of this Indenture and any applicable Series Supplement in accordance with and within the time periods provided for in this Indenture and in each applicable Series Supplement.

Section 7.10 Performance of Agreements; Termination of Ground Lease Sites, Easement Sites and Site Management Agreements. The Issuer shall and shall cause each Asset Entity to 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, Tenant Leases, Ground Leases, Easements and Site Management Agreements and (iii) all other agreements entered into or assumed by such Person in connection with the Tower Sites, and will 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 clause (ii) or (iii) of this Section 7.10 would not reasonably be expected to have a Material Adverse Effect. Notwithstanding the foregoing to the contrary, the Issuer and the Asset Entities shall be permitted to terminate or sell (including by assignment) (i) the ground lease with respect to any Ground Lease Site, (ii) the easement with respect to any Easement Site and (iii) the Site Management Agreement with respect to any Managed Site in each case the termination or sale of which the Asset Entities reasonably deem necessary in accordance with prudent business practices; provided, that (i) the Issuer shall provide written notice to the Servicer and the Indenture Trustee of such determination not later than thirty (30) days prior to such termination or sale, (ii) together with such notice the Issuer shall provide supporting information reasonably acceptable to the Servicer that immediately following such termination or sale the DSCR will be equal to or greater than the DSCR immediately prior to such termination or sale and (iii) if (1) the aggregate Allocated Note Amount with respect to (x) each such Tower Site for which termination or sale has occurred under this Section 7.10 and (y) the Tower Site for which a termination or sale is proposed, is greater than 5% of the Initial Class Principal Balance of all Classes of Notes, or (2) if after giving effect to the proposed termination or sale, the Tenant Quality Tests would not be satisfied, the Issuer has delivered a Rating Agency Confirmation and during a Special Servicing Period, the Servicer consents to such termination or sale.

Section 7.11 Advance Rents; New Tenant 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 Obligors, at the request of the Indenture Trustee or the Servicer’s request, shall furnish the Indenture Trustee or Servicer, as applicable, with executed copies of all Tenant Leases entered into after the Initial Closing Date. Each such new Tenant Lease other than (x) a Tenant Lease relating to the addition of new Tower Sites pursuant to an existing Master Agreement, (y) new Tenant Leases in the form of existing Tenant Leases with the same tenants or (z) a Governmental Tenant Lease shall specifically provide that such Tenant Lease (i) is subordinate to the Deeds of Trust; provided that the Indenture Trustee agrees not to disturb the applicable Tenant’s possession for so long as such Tenant is not in default under the terms of the applicable lease (as evidenced by an agreement substantially in the form of Exhibit D (an “SNDA”); (ii) that such Tenant attorns to the Indenture Trustee; (iii) that the attornment of such Tenant shall not be terminated by foreclosure; and (iv) that in no event shall the Indenture Trustee, as holder of the Deeds of Trust or as successor landlord, be liable to such 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 to the related Tower Site. On the Initial 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 (in the form of Exhibit E) enabling the Manager (on behalf of the Indenture Trustee) to execute SNDAs as attorney-in-fact of the Indenture Trustee and the Servicer (with the appropriate information completed therein) without any material changes being made to the form thereof.

Section 7.12 Management Agreement.

(a) The Issuer shall, and shall cause the Asset Entities as applicable to, (i) perform and observe all of the material terms, covenants and conditions of the Management Agreement on the part of each Asset Entity to be performed and observed, (ii) promptly notify the Indenture Trustee and the Servicer of any notice to any of the Asset Entities of any material default under the Management Agreement of which it is aware, and (iii) prior to termination of the Manager in accordance with the terms of the Management Agreement, to renew the Management Agreement prior to each expiration date thereunder in accordance with its terms. If any of the Asset Entities shall default in the performance or observance of any material term, covenant or condition of the Management Agreement on the part of the Asset Entities 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 Asset Entities from any of their obligations hereunder or under the Management Agreement, the Issuer grants the Indenture Trustee or the Servicer on its behalf the right, upon prior written notice to the Asset Entities, 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 Asset Entities to be performed or observed; provided, however, that neither the Indenture Trustee nor the Servicer will be under any obligation to pay such sums or perform such acts.

(b) The Issuer shall not permit the Asset Entities to surrender, terminate, cancel, or modify (other than non-material changes), the Management Agreement, or enter into any other Management Agreement with any new Manager (other than an Acceptable Manager), or consent to the assignment by the Manager of its interest under the Management Agreement, in each case without delivery of Rating Agency Confirmations from each of the Rating Agencies and written consent of the Servicer. If at any time the Servicer consents to the appointment of a new Manager, or if an Acceptable Manager shall become the Manager, such new Manager, or the Acceptable Manager, as the case may be, then the Issuer shall cause the Asset Entities to, as a condition of the Servicer’s consent, 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 delivered on the Initial Closing Date.

(c) The Servicer shall have the right to require that the Manager be replaced with a Person chosen by the Issuer (or, if an Event of Default has occurred and is then continuing, the Indenture Trustee) and reasonably acceptable to the Servicer, upon the earliest to occur of any one or more of the following events: (i) the declaration of an Event of Default, (ii) the DSCR falls to less than 1.10x as of the end of any calendar quarter and the Servicer reasonably determines that such decline in the DSCR is primarily attributable to acts or omissions of the Manager rather than factors affecting the Asset Entities’ industry generally, (iii) the Manager has engaged in fraud, gross negligence or willful misconduct in connection with its performance under the Management Agreement or (iv) default on the part of the Manager in the performance of its obligations under the Management Agreement, and, with respect to the events specified in clauses (iii) and (iv) such event could reasonably be expected to have a Material Adverse Effect and remains unremedied for 30 days after the Manager receives written notice thereof from the Servicer (provided, however, if such default is reasonably susceptible of cure, but not within such 30-day period, then the Manager may be permitted up to an additional 60 days to cure such default provided that the Manager diligently and continuously pursues such cure).

The Indenture Trustee and the Servicer are each permitted to utilize and in good faith rely upon the advice of the Manager (or to, 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) utilize 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 and substitutions; and confirmation of compliance by the Issuers with the provisions hereunder and under the other Transaction Documents and neither the Indenture Trustee nor the Servicer shall have any liability with respect thereto.

Section 7.13 Maintenance of Office or Agency by Issuer.

(a) The Issuer shall maintain an office, agency or address where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange, and where notices and demands to or upon the Issuer in respect of the Notes, this Indenture and any Indenture Supplement may be served. The Issuer will 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 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 hereby appoints the Indenture Trustee to receive all such presentations, surrenders, notices, and demands on behalf of the Issuer. The Issuer hereby appoints the Corporate Trust Office as its agency for such purposes.

(b) The Issuer 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. The Issuer will give prompt written notice to the Indenture Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 7.15 Estoppel Certificates.

(a) Within ten (10) Business Days following a request by the Indenture Trustee or the Servicer, the Issuer shall provide to the Indenture Trustee and the Servicer a duly acknowledged written statement (upon which the Indenture Trustee and the Servicer may rely) confirming (i) the amount of the outstanding principal balance of the Notes, (ii) the terms of payment and maturity date of the Notes, (iii) the date to which interest has been paid, (iv) whether any offsets or defenses exist against the Obligations, and if any such offsets or defenses are alleged to exist, the nature thereof shall be set forth in detail and (v) that this Indenture, the

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 Issuer shall not, and shall not permit the Asset Entities to, create, incur, assume, guarantee, or otherwise become or remain directly or indirectly liable with respect to any Indebtedness except for the following (collectively, “Permitted Indebtedness”):

(a) The Obligations;

(b) (i) Unsecured trade payables not evidenced by a note and arising out of purchases of goods or services in the ordinary course of business and (ii) Indebtedness incurred in the financing of equipment or other personal property used at any Tower Site in the ordinary course of business; provided, however, (A) such trade payables are payable not later than ninety (90) days after the original invoice date and are not overdue by more than thirty (30) days and (B) the aggregate amount of such trade payables and Indebtedness relating to financing of equipment and personal property or otherwise referred to in clauses (i) and (ii) above outstanding does not, at any time, exceed $1,500,000 in the aggregate for all the Asset Entities.

In no event shall any Indebtedness other than the Obligations be secured, in whole or in part, by the Collateral or other Assets or any portion thereof or interest therein and any proceeds of any of the foregoing.

Section 7.17 No Liens. Neither the Issuer nor the Asset Entities shall create, incur, assume or permit to exist any Lien on or with respect to the Tower Sites or any other Collateral except Permitted Encumbrances.

Section 7.20 Bankruptcy, Receivers, Similar Matters. An Obligor shall not apply for, consent to, or aid, solicit, support, or otherwise act, cooperate or collude to cause the appointment of or taking possession by, a receiver, trustee or other custodian for all or a substantial part of the assets of any other Obligor. As used in this Indenture, an “Involuntary Obligor Bankruptcy” shall mean any involuntary case under the Bankruptcy Code or any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, in which any Obligor is a debtor or any portion of the Assets is property of the estate therein. An Obligor 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 Obligor Bankruptcy. In any Involuntary Obligor Bankruptcy, the other Obligors shall not, without the prior written consent of the Indenture Trustee and the Servicer, consent to the entry of any order, file any motion, or support any motion (irrespective of the subject of the motion), and such Obligors shall not file or support any plan of reorganization. In any Involuntary Obligor Bankruptcy the other Obligors shall do all things reasonably requested by the Indenture Trustee and the Servicer to assist the Indenture Trustee and the Servicer in obtaining such relief as the Indenture Trustee and the Servicer shall seek, and shall in all events vote as directed by the Indenture Trustee. Without limitation of the foregoing, each such Obligor shall do all things reasonably requested by the Indenture Trustee to support any motion for relief from stay or plan of reorganization proposed or supported by the Indenture Trustee.

(b) Compliance with ERISA. Except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, the Issuer shall not, and shall not permit the Asset Entities 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 any Employee Benefit Plan which establishment or amendment could result in liability to the Obligors or any ERISA Affiliate or increase the benefits obligation of the Obligors; provided that if the Issuer is in default of this covenant under subsection (i), the Issuer shall be deemed not to be in default if such default results solely because (x) any portion of the Notes have been, or will be, funded with plan assets of any Plan and (y) the purchase or holding of such portion of the Notes by such Plan constitutes a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation of applicable Similar Law.

The Issuer hereby appoints 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 Debt Service Sub-Account to be made on behalf of the Issuer by the Paying Agent, and no amounts so withdrawn from the Debt Service Sub-Account for payments of the Notes and other Obligations shall be paid over to the Issuer. All such payments shall be made based on the information set forth in the Servicing Report.

(c) 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 on an Issuer Request; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), 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 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. The Indenture Trustee shall also adopt and employ, at the expense and direction of the Issuer, 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 7.23 Ground Leases.

(a) Modification. Except as provided in this Section 7.23, the Issuer shall not, and shall not permit the Asset Entities to, 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 Asset Entities shall be permitted, without the Servicer’s consent, to:

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

(ii) terminate or sell (including by way of assignment) any Ground Lease which the Issuer reasonably deems necessary in accordance with prudent business practices subject to the provisions of Section 7.10; 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 Issuer shall have provided the Servicer with at least ten (10) days’ 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 Issuer shall have provided the Servicer with a copy of the Amended Ground Lease certified by the Issuer as being complete and correct, together with an Estoppel from the applicable Ground Lessor;

(B) on or prior to execution and delivery of the Amended Ground Lease, the Issuer shall have provided the Servicer with a Phase I environmental assessment report and, if any such Phase I environmental assessment report reveals any condition that in the Servicer’s reasonable judgment so warrants, a Phase II environmental assessment report, which in either case concludes that the subject property does not contain any Hazardous Materials (except in quantities that do not violate applicable Environmental Laws) and is not in violation of any applicable Environmental Laws;

(C) if the Ground Lease being replaced is with respect to a Mortgaged Site, simultaneously with the execution and delivery of the Amended Ground Lease, the Indenture Trustee and the Servicer shall have received (i) an Amended Deed of Trust executed and delivered by a duly authorized officer of the applicable Asset Entity encumbering the property included under the Amended Ground Lease, (ii) an endorsement to (or replacement of) the existing Title Policy covering such Mortgaged Site and (iii) a Survey with respect thereto (unless the general survey exception in the Title Policy for such Mortgaged Site is eliminated without a Survey); and

(D) the Issuer 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.

(b) Performance of Ground Leases. The Issuer shall cause the Asset Entities to 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 permit the Asset Entities to cause or suffer to occur any material breach or default in any of such obligations. The Issuer shall cause the Asset Entities to exercise any option to renew or extend any Ground Lease; provided that an Asset Entity may elect not to exercise any such option if, and to the same extent that such Asset Entity would be entitled to terminate or sell such Ground Lease pursuant to Section 7.23(a). If the Asset Entity does intend to exercise such option, the Issuer shall give the Servicer thirty (30) days prior written notice thereof. If any Asset Entity fails to renew a Ground Lease which is required to be renewed pursuant to this Section 7.23(b), such Asset Entity hereby grants to each of the Indenture Trustee and the Servicer a power of attorney to renew such Ground Lease on behalf of such Asset Entity.

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

(d) Servicer’s Right to Cure. Each Obligor agrees that 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 Obligors question or deny such assertion), then, subject to (i) the terms and conditions of the applicable Ground Lease and (ii) the Asset Entities’ right to terminate or sell Ground Leases in accordance with Section 7.23(a), the Servicer, upon five (5) Business Days’ prior written notice to the Issuer, unless 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 the Servicer deems reasonably necessary, including, without limitation, (i) performance or attempted performance of the applicable Asset Entity’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 Lease Site for any or all of such purposes. Upon the Indenture Trustee’s or the Servicer’s request, the 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 Issuer shall pay to the Indenture Trustee or the Servicer, as applicable, within five (5) 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, together with interest thereon from the date of expenditure at the rate provided for Servicing Advances in the Servicing Agreement.

(e) Legal Action. The Obligors shall not commence any action or proceeding against any Ground Lessor or affecting or potentially affecting any Ground Lease or the Asset Entities’ 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 Issuer shall notify the Indenture Trustee and the Servicer immediately if any action or proceeding shall be commenced between any Ground Lessor and such Asset Entity, or affecting or potentially affecting any Ground Lease or such Asset Entity’s or the Indenture Trustee and the Servicer’s interest therein (including, without limitation, any case commenced by or against any Ground Lessor under the Bankruptcy Code). Each Obligor hereby grants the Indenture Trustee and the Servicer the option, exercisable upon notice from the Indenture Trustee or the Servicer to the Issuer, to participate in any such action or proceeding with counsel of the Indenture Trustee or the Servicer’s choice. Each Obligor 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 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 applicable Asset Entity shall not elect to treat the Ground Lease as terminated but, rather, shall elect to remain in possession of the applicable Ground Lease Site and the leasehold estate under such Ground Lease. The lien of the Deed of Trust covering any such Mortgaged Site does and shall encumber and attach to all of the Asset Entity’s rights and remedies at any time arising under or pursuant to Section 365 of the Bankruptcy Code, including without limitation, all of such Asset Entity’s rights to remain in possession of such Tower Site and the leasehold estate.

(ii) Each Asset Entity acknowledges and agrees that in any case commenced by or against such Asset Entity under the Bankruptcy Code, the Indenture Trustee by reason of the liens and rights granted under the Deed of Trust covering a Mortgaged Site shall have a substantial and material interest in the treatment and preservation of such Asset Entity’s rights and obligations under the related Ground Lease, and such Asset Entity agrees to, in any such bankruptcy case, provide to the Indenture Trustee immediate and continuous reasonably adequate protection of such interests. Such Asset Entity 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 Asset Entity’s 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 Lease Site.

(B) Such Asset Entity shall serve the Indenture Trustee and Servicer with copies of all notices, pleadings and other documents relating to or affecting the Ground Lease or the applicable Ground Lease Site. Such Asset Entity (i) will contemporaneously serve on the Indenture Trustee and Servicer any notice, pleading or document served by such Asset Entity on any other party in the bankruptcy case, and (ii) any notice, pleading or document served upon or received by such Asset Entity from any other party in the bankruptcy case to be served by such Asset Entity on the Indenture Trustee and Servicer promptly upon receipt by such Asset Entity.

(C) Upon written request of the Indenture Trustee or the Servicer, such Asset Entity will assume the Ground Lease, and take such steps as are necessary to preserve such Asset Entity’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 Section 365(d) of the Bankruptcy Code to the extent it is applicable.

(g) If the Asset Entity or the applicable Ground Lessor seek to reject any Ground Lease or have the Ground Lease deemed rejected, then prior to the hearing on such rejection such Asset Entity will give the Indenture Trustee and the Servicer, subject to applicable law, 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 (which shall be at the Servicer’s direction) so elect to assume and assign the Ground Lease, such Asset Entity will, 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 such Asset Entity agrees that 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.

Such Asset Entity agrees to join with and support any request by the Indenture Trustee to grant and approve the foregoing 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 Asset Entity hereby appoints the Indenture Trustee as its attorney in fact to act on behalf of such Asset Entity 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 shall be present, unconditional, irrevocable, durable and coupled with an interest.

Section 7.24 Easements.

(a) Modification. Except as provided in this Section 7.24, the Issuer shall not, and shall not permit the Asset Entities to, modify or amend any material substantive or economic terms of, or, subject to the terms herein, 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 and Servicer’s prior written consent shall be null and void and of no force or effect.

(A) the Issuer shall have provided the Servicer with at least ten (10) day’s prior written notice of the execution of the Amended Easement, together with a summary of the economic terms thereof, and, following execution and delivery of the Amended Easement, the Issuer shall have provided the Servicer with a copy of the Amended Easement certified by Issuer as being true, accurate and complete;

(B) on or prior to execution and delivery of the Amended Easement, the Issuer shall have caused the applicable Asset Entity to provide the Servicer with a Phase I environmental assessment report and, if any such Phase I environmental assessment report reveals any condition that in the Servicer’s reasonable judgment so warrants, a Phase II environmental assessment report, which in either case concludes that the subject property does not contain any Hazardous Materials (except for quantities that do not violate applicable Environmental Laws) and is not in violation of any applicable Environmental Laws;

(C) if the Easement being replaced is with respect to a Mortgaged Site, simultaneously with the execution and delivery of the Amended Easement, the Indenture Trustee and the Servicer shall have received (i) an Amended Deed of Trust executed and delivered by a duly authorized officer of the applicable Asset Entity encumbering the property included under the Amended Easement, (ii) an endorsement to (or replacement of) the existing Title Policy covering such Mortgaged Site and (iii) a Survey with respect thereto (unless the general survey exception in the Title Policy for such Mortgaged Site is eliminated without a Survey); and

(D) the Issuer shall pay or reimburse the Indenture Trustee for all reasonable costs and expenses incurred by the Indenture Trustee and 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.

(b) Performance of Easements. The Issuer shall cause the Asset Entities to fully perform as and when due each and all of their obligations under each Easement in accordance with the terms of such Easement, and shall not permit the Asset Entities to, cause or suffer to occur any material breach or default in any of such obligations. The Issuer shall cause the Asset Entities to exercise any option to renew or extend any Easement; provided that an Asset Entity may elect not to exercise any such option if, and to the same extent that such the Asset Entity would be entitled to terminate or sell such Easement pursuant to Section 7.24(a). If the Asset Entity does intend to exercise such option, the Issuer shall give the Servicer thirty (30) days prior written notice thereof. If any Asset Entity fails to renew an Easement which is required to be renewed pursuant to this Section 7.24(b), such Asset Entity hereby grants to each of the Indenture Trustee and the Servicer a power of attorney to renew such Easement on behalf of such Asset Entity.

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

(d) The Indenture Trustee’s and Servicer’s Right to Cure. Each Obligor agrees that if any Easement Default shall occur and be continuing, or if any fee owner asserts that an Easement Default has occurred (whether or not the Obligors question or deny such assertion), then, subject to (i) the terms and conditions of the applicable Easement, and (ii) the Asset Entities’ right to terminate or sell Easements in accordance with Section 7.24(a), the Servicer, upon five (5) Business Days prior written notice to the Issuer, unless the Servicer reasonably determines that a shorter period (or no period) of notice is necessary to protect the

Indenture Trustee’s interest in the Easement, may (but shall not be obligated to) take any action that the Servicer deems reasonably necessary, including, without limitation, (i) performance or attempted performance of the applicable Asset Entity’s obligations under the applicable Easement, (ii) curing or attempting to cure any actual or purported Easement Default, (iii) mitigating or attempting to mitigate any damages or consequences of the same and (iv) entry upon the applicable Easement Site for any or all of such purposes. Upon the Indenture Trustee’s or the Servicer’s request, the Issuer shall submit satisfactory evidence of payment or performance of any of its obligations under each Easement. 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 Issuer shall pay to the Indenture Trustee or the Servicer, as applicable, within five (5) 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, together with interest thereon from the date of expenditure at the rate provided for Servicing Advances in the Servicing Agreement.

Section 7.25 Managed Sites.

(a) Modification. Except as provided in this Section 7.25, the Issuer shall not, and shall not permit the Asset Entities to, modify or amend any material substantive or economic terms of, or, subject to the terms herein, terminate or surrender any Site Management Agreement, 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 Site Management Agreement without the Indenture Trustee and Servicer’s prior written consent shall be null and void and of no force or effect. Notwithstanding the foregoing to the contrary, the Asset Entities shall be, without the Indenture Trustee and Servicer’s consent, to:

(i) extend the terms of the Site Management Agreement on commercially reasonable substantive and economic terms;

(ii) terminate or sell (including by way of assignment) any Site Management Agreement which the Issuer reasonably deems necessary in accordance with prudent business practices subject to the provisions of Section 7.10; and

(b) Performance of Site Management Agreements. The Issuer shall cause the Asset Entities to fully perform as and when due each and all of their obligations under each Site Management Agreement in accordance with the terms of such Site Management Agreement, and shall not permit the Asset Entities to, cause or suffer to occur any material breach or default in any of such obligations.

Section 7.31 Disposition of Tower Sites; Reinvestment of Disposition Proceeds. The Asset Entities will not dispose or otherwise transfer Tower Sites except as expressly permitted in this Section 7.31. Prior to the second (2nd) anniversary of the Initial Closing Date, the Asset Entities will not dispose of any Tower Sites except: (i) the Asset Entities may in each period of 12 months commencing with the Initial Closing Date, dispose of Tower Sites having an aggregate Allocated Note Amount less than or equal to $5,000,000, and (ii) may dispose of a Tower Site if required in the Manager’s reasonable judgment, in order to cure a breach of a representation, warranty or other default with respect to such Tower Site. From and after the second (2nd) anniversary of the Initial Closing Date the Asset Entities may dispose of Tower Sites at any time; provided that (i) during a Special Servicing Period, no Tower Site dispositions may be made without the Servicer’s consent and (ii) if, after giving effect to any proposed disposition of a Tower Site, the Tenant Quality Tests would not be satisfied, the Issuer shall have delivered to the Indenture Trustee a Rating Agency Confirmation with respect thereto. In connection with each disposition of a Tower Site, the Issuer shall prepay the Notes in accordance with Section 2.09(b) in an amount equal to the Release Price, together with the applicable Prepayment Consideration if the prepayment of any Class of any Series of Notes occurs more than six (6) months prior to the Anticipated Repayment Date for such Class of such Series of Notes, provided that in any 12-month period dispositions of Tower Sites having an aggregate Allocated Note Amount of up to $5,000,000 may be made without any prepayment if (1) the proceeds from the disposition of such Tower Sites is an amount equal to or greater than 125% of the Allocated Note Amount of such Tower Sites, (2) the Issuer delivers a notice to the Servicer that the net cash proceeds of such disposition will be deposited into an account with the Indenture Trustee (the “Liquidated Tower Replacement Account”) and within six (6) months will be used by an Asset Entity to acquire Tower Sites and (3) the pro forma Debt Service Coverage Ratio following the disposition is not less than the Debt Service Coverage Ratio immediately prior thereto after giving pro forma effect to the receipt of proceeds in connection with such disposition. Funds deposited in the Liquidated Tower Replacement Account may be used by the Asset Entities to acquire Tower Sites, provided that the Tower Sites so acquired meet the requirements described in clauses (ii) through (vi) of Section 7.32, as if the acquired Tower Sites were Replacement Tower Sites. Any funds remaining in the Liquidated Tower Replacement Account on the Payment Date falling more than six months after the date of initial deposit will be withdrawn by the Indenture Trustee on such Payment Date and applied to prepay the Notes pursuant to Section 2.09(b). The rights set forth in this Section 7.31 shall be in addition to the rights related to substitutions of Tower Sites set forth in Section 7.32. Prior to the first such disposition of Tower Sites, the Issuer will open the Liquidated Tower Replacement Account with the Indenture Trustee.

are subject to a Ground Lease, such Ground Lease has a term, including all available extensions thereof, of not less than 15 years from the date of substitution, (x) the weighted average Remaining Term of the Tenant Leases for the replacement Tower Sites is equal to or longer than the weighted average Remaining Term of the Tenant Leases on the replaced Tower Sites, (y) the Maintenance Capital Expenditures for the Replacement Tower Sites are not materially greater than the Maintenance Capital Expenditures for the replaced Tower Sites, in each case unless Rating Agency Confirmation is obtained, and (z) if during a Special Servicing Period, the Servicer consents to such substitution, (iii) after the substitution the DSCR shall be at least equal to the DSCR as of the date immediately preceding the substitution, (iv) the Indenture Trustee and the Servicer will have received such legal opinions as may be reasonably requested, (v) the Issuer shall, or shall have caused the applicable Asset Entity to, have reimbursed the Indenture Trustee and the Servicer for all third party out-of-pocket costs and expenses incurred by the Indenture Trustee and the Servicer in relation to such substitution, (vi) the Issuer shall, or shall have caused the applicable Asset Entity to, have delivered a Phase I environment assessment report, and if any Phase I environmental assessment report conducted pursuant to the immediately preceding clause reveals any condition that in the Servicer’s reasonable judgment so warrants, a Phase II environmental assessment report, to the Indenture Trustee and the Servicer, and such report or reports do not disclose any material violation of applicable Environmental Laws and (vii) if any such Replacement Tower Site is a Mortgaged Site, a Deed of Trust, a Title Policy and a Survey with respect thereto (unless the general survey exception in the Title Policy for such Mortgaged Site is eliminated without a Survey with respect thereto). Additionally, the Asset Entities may convert any Ground Leased Site or an Easement Site to an Owned Fee Site or any Managed Site to an Owned Fee Site at any time; provided that such conversion complies with clauses (ii)(z) and (iii) through (vii) of this Section 7.32. No such conversion will be counted towards the 5% limitation described in clause (i) above.

Section 7.33 Environmental Remediation. Each Asset Entity agrees to commence, within 30 days (or such shorter period as may be required by law) after written demand by the Indenture Trustee or the Servicer and diligently prosecute to completion any Remedial Work of any kind required by it under applicable Environmental Laws. If an Asset Entity fails to promptly commence and diligently pursue to completion any Remedial Work, the Servicer may (but will not be obligated to), upon 30 days prior notice to the Issuer of its intention to do so, cause such Remedial Work to be performed. If requested by the Servicer in connection with any Remedial Work with respect to any Tower Site that is projected to cost in excess of $500,000, the applicable Asset Entity agrees to cause such Remedial Work to be performed by licensed contractors and under the supervision of a consulting engineer, each approved in advance by the Servicer, such approval to not be unreasonably withheld. The Obligors agree to pay or reimburse the Servicer for all expenses reasonably incurred by the Servicer in connection with (a) monitoring, reviewing or performing such Remedial Work, (b) investigating potential environmental claims against the Asset Entities or (c) participating in any legal or administrative proceeding concerning any applicable Environmental Law will be required to be paid or reimbursed by the Asset Entities.

(d) Any amounts recovered from the Tower Sites, the Assets, Tenant Leases or any Collateral and the proceeds from any of the foregoing for the Notes and other Obligations after an Event of Default may be applied by the Indenture Trustee 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 in its sole discretion shall determine; provided, however, that any such payments on the Notes will be made in accordance with the priorities set forth in Article V of this Indenture.

(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.

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 Asset Entities, the Issuer, 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 shall cure any Event of Default hereunder.

Such notice shall set forth the process established by the Indenture Trustee for selecting a Controlling Class Representative. No appointment of any Person as a Controlling Class Representative shall be effective until such Person provides the Indenture Trustee with written confirmation of its acceptance of such appointment, that it will keep confidential all information received by it as Controlling Class Representative hereunder or otherwise with respect to the Notes, the Assets and/or the Servicing Agreement, 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 Servicing Agreement may deal (including their names, titles, work addresses and facsimile numbers). No Affiliate of the Issuer may act as Controlling Class Representative.

(b) Within ten (10) Business Days (or as soon thereafter as practicable if the Controlling Class consists of Book-Entry Notes) of any change in the identity of the Controlling Class 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, of the Controlling Class and the Servicer a notice setting forth the identity of the new Controlling Class 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) of the Controlling Class, 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 such 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 Class Representative or any of the Noteholders (or, if applicable, Note Owners) of the Controlling Class. In addition to the foregoing, within two (2) Business Days of the selection, resignation or removal of a Controlling Class Representative, the Indenture Trustee shall notify the parties to this Indenture of such event.

(c) A Controlling Class 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) of the Controlling Class. The Noteholders (or, in the case of Book-Entry Notes, the Note Owners) of the Controlling Class whose Notes represent more than 50% of the Outstanding Class Principal Balance of the Controlling Class shall be entitled to remove any existing Controlling Class Representative by giving written notice to the Indenture Trustee and to such existing Controlling Class Representative.

(d) Once a Controlling Class Representative has been selected pursuant to this Section 10.05, each of the parties to the Servicing Agreement and each Noteholder (or Note Owner, if applicable) shall be entitled to rely on such selection unless a majority of the Noteholders (or, in the case of Book-Entry Notes, the Note Owners) of the Controlling Class, by Class Principal Balance, or such Controlling Class Representative, as applicable, shall have notified the Indenture Trustee and each other party to the Servicing Agreement and each Noteholder (or, in the case of Book-Entry Notes, Note Owner) of the Controlling Class, in writing, of the resignation or removal of such Controlling Class Representative.

(e) Any and all expenses of the Controlling Class Representative shall be borne 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 Notes of the Controlling Class, pro rata according to their respective Percentage Interests in such Class. Notwithstanding the foregoing, if a claim is made against the Controlling Class Representative by an Obligor with respect to the Servicing Agreement or the Notes, the Controlling Class 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 Class Representative had acted in good faith, without gross negligence or willful 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 Class Representative) the Servicer on behalf of the Indenture Trustee shall, subject to the Servicing Agreement, assume the defense of any such claim against the Controlling Class Representative.

Section 10.06 Certain Rights and Powers of the Controlling Class 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 Asset Entities, the Controlling Class 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 Class Representative has objected in writing within ten (10) Business Days of having been notified thereof and having been provided with information with respect thereto reasonably requested no later than the fifth (5th) Business Day after notice thereof (provided, that if such written objection has not been received by the Servicer within such ten (10) Business Day period, then the Controlling Class Representative’s approval will be deemed to have been given).

If the Controlling Class Representative affirmatively approves or is deemed to have approved in writing such a request, the Servicer will implement the action for which approval was sought. If the Controlling Class Representative disapproves of such a request

within the ten (10) Business Day period referred to in the preceding paragraph, the Servicer must (unless it withdraws the request) revise the request and deliver to the Controlling Class Representative a revised request promptly and in any event within thirty (30) days after such disapproval. The Servicer will 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 Class Representative to disapprove a request within ten (10) Business Days after its receipt thereof and (y) (1) the passage of sixty (60) days following the Servicer’s delivery of its initial request to the Controlling Class 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 Class 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 Class Representative and, if any Controlling Class 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 Class 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 other Section of the Servicing Agreement, 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, or the Indenture Trustee, to any material claim, suit or liability, or (C) materially expand the scope of the Servicer’s responsibilities under the Servicing Agreement. In addition, the Controlling Class 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 Issuer or any of the Asset Entities (including by way of foreclosure on the equity interests of the Issuer or the direct or indirect equity interests of Asset Entities) 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 Class 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 Servicing Agreement, or for errors in judgment; provided, however, that the Controlling Class Representative shall not be protected against any liability which would otherwise be imposed by reason of willful misfeasance, gross negligence or reckless disregard of obligations or duties under the Servicing Agreement. Each Noteholder and Note Owner acknowledges and agrees, by its acceptance of its Notes or interest therein, that the Controlling Class 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 Class Representative may act solely in the interests of the Noteholders and Note Owners of the Controlling Class, that the Controlling Class Representative does not have any duties to the Noteholders and Note Owners of any Class of Notes other than the Controlling Class, that the Controlling Class Representative may take actions that favor the interests of the Noteholders and Note Owners of the Controlling Class over the interests of the Noteholders and Note Owners of one or more other Classes of Notes, that the

100

Controlling Class Representative will not be deemed to have been grossly negligent or reckless, or to have acted in bad faith or engaged in willful misfeasance by reason of its having acted solely in the interests of the Controlling Class and that the Controlling Class Representative shall have no liability whatsoever for having so acted, and no Noteholder may take any action whatsoever against the Controlling Class 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 Issuer covenant that if there is an Event of Default described in Section 10.01(a), the Issuer 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 its agents and counsel and other amounts due and owing to the Indenture Trustee pursuant to Section 11.05.

(b) Subject to the provisions of Section 10.02 and Section 15.16, in case the Issuer 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 Issuer or other obligor upon such Notes and collect in the manner provided by law out of the property of the Issuer or other obligor upon such Notes wherever situated, the monies adjudged or decreed to be payable.

(c) Subject to the provisions of Section 15.16, 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 Issuer 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 been appointed for or taken possession of the Issuer or their property or such other obligor, or in case of any other comparable judicial Proceedings relative to the Issuer or other obligor upon the Notes, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, irrespective of whether the Outstanding Class Principal Balance shall then be due and payable as therein

101

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 Issuer, 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.

(f) Subject to the provisions of Section 15.16, 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

102

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 15.16):

(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 Issuer 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;

(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 Issuer, 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

(vi) demand, collect, take possession of, receive, settle, compromise, adjust, ▇▇▇ 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

103

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 Issuer and the Noteholders that there be at all times sufficient funds for the payment of all Outstanding 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 Issuer’s 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 15.16, 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 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 sixty (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 sixty (60) day period by Noteholders representing more than 50% of the Outstanding Class Principal Balance of all Classes of Notes.

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 15.16.

104

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.

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,

105

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 Indenture Trustee, the filing by any party litigant (other than the 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 the 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 the 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 Issuer covenants (to the extent that it may lawfully do so) that it 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 Issuer (to the extent that it may lawfully do so) hereby expressly waives 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 Issuer 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 Issuer.

Section 10.19 Waiver. The Issuer hereby expressly waives, 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 Issuer acknowledges and agrees that ten (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 Issuer within the meaning of the UCC.

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. 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 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. 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 Issuer, the Asset Entities, Global Tower, LLC, the Servicer, 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. The Indenture Trustee shall not be responsible for recomputing, recalculating or verifying any information provided by the Servicer or Manager pertaining to any report, distribution statement or officer’s certificate.

(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 willful 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

107

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 or the direction of Noteholders entitled to at least 25% (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.

(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 or Servicer Termination Event unless either (1) a Responsible Officer shall have actual knowledge of such Event of Default or Servicer Termination Event (as defined in the Servicing Agreement) or (2) written notice of such Event of Default or Servicer Termination Event 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 or Servicer Termination Event.

(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, the protections, immunities and indemnities afforded to that Person in its capacity as Indenture Trustee hereunder shall also be afforded to such Person in its capacity as Note Registrar, as the case may be.

(ix) If the same Person is acting in as 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.

(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 Issuer.

109

(ii) the Indenture Trustee may consult with counsel and any written 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 reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby satisfactory to the Indenture Trustee, in its reasonable 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) 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 reasonably 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;

110

(vi) except as contemplated by Section 11.06, the Indenture Trustee shall not be required to give any bond or surety in respect of the execution of the trusts created hereby or the powers granted hereunder;

(vii) the Indenture Trustee may execute any of the trusts or powers vested in it by this Indenture or any Indenture Supplement and may perform any its duties hereunder, either directly or by or through agents, attorneys, or custodians, and the Indenture Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney, or custodian appointed by the Indenture Trustee with due care; provided, that the use of agents, attorneys, or custodians shall not be deemed to relieve the Indenture Trustee of any of its duties and obligations hereunder (except as expressly set forth herein);

(viii) the Indenture Trustee shall not be responsible for any act or omission of the Servicer (unless, in the case of the Indenture Trustee, it is acting as Servicer); and

(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.

(x) the rights, protections, immunities and indemnities afforded to the Indenture Trustee pursuant to this Indenture shall also be afforded to the Indenture Trustee under the other Transaction Documents.

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 Issuer’s use of the proceeds from the Notes, or responsible for any statement of the Issuer 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.

111

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 Collection 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 Fee earned in respect of the Notes through the end of the then most recently ended Interest Accrual Period as compensation for all services rendered by the Indenture Trustee, respectively, hereunder. The Indenture Trustee Fee shall accrue during each Interest Accrual Period at a rate of 0.009% per annum on the Outstanding Principal Balance of all the Notes as of the Payment Date that coincided with or immediately follows the first day of such Interest Accrual Period (or, in the case of the initial Collection Period, on a principal balance equal to $250,000,000). The Indenture Trustee Fee shall be calculated on a 30/360 Basis.

(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 Collection 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 will 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 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 any expense that constitutes (1) allocable overhead, such as costs for office space, office equipment, supplies and related expenses, employee salaries and related expenses and similar internal costs and expenses, (2) any loss, liability, damage, claim or expense specifically required to be borne thereby pursuant to the terms of this Indenture or (3) any loss, liability, damage, claim or expense incurred by reason of any breach on the part of the Indenture Trustee of any of its representations, warranties or covenants contained herein or any willful misfeasance, bad faith or negligence in the performance of, or reckless disregard of, such Person’s obligations and duties hereunder. Without limiting the foregoing, the Issuer agrees 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 Collection Account. The Indenture Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Indenture Trustee to so notify the Issuer shall not relieve the Issuer of its 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 Issuer under this Section 11.05.

112

(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 Asset Entity (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 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 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 ▇▇▇▇▇’▇ and a short-term unsecured debt rating of no less than “F-1” from Fitch and “P-1” from ▇▇▇▇▇’▇ (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 Indenture Trustee may have normal banking and trust relationships with the Asset Entities, 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 Issuer and the Asset Entities 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 sixty (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 Issuer shall use its 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

113

copy of such instrument shall be delivered to the other parties to this Indenture, the Servicer and to the Noteholders by the Issuer. If no successor indenture trustee shall have been so appointed and have accepted appointment within thirty (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 Issuer 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 Indenture Trustee’s continuing to act in such capacity would (as confirmed in writing to the Issuer by any Rating Agency) result in the qualification, downgrade or withdrawal of the rating then assigned to any Class of Notes rated by such Rating Agency (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), then the Issuer, 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 Issuer.

(c) The holders of Notes entitled to at least 51% 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 Issuer, 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 Indenture Trustee within thirty (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 Issuer, 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

114

rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as 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 Issuer, 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.

(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 indenture trustee hereunder to the Issuer, 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 all or substantially all of 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

115

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.

(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.

(d) Any separate trustee or co-trustee may, at any time, constitute the Indenture Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture or any Indenture Supplement on its behalf and in its name. 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 Issuer, the Initial Purchasers, the Servicer, the Controlling Class 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 Corporate Trust Office.

(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 Issuer, the Rating Agencies, and the Controlling Class 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) this Indenture, and any applicable Indenture Supplements and any amendments and exhibits hereto or thereto; (ii) the Servicing Agreement, each sub-servicing agreement delivered to the Indenture Trustee since the Closing Date and any amendments and exhibits or thereto; (iii) all Indenture Trustee Reports actually

116

delivered or otherwise made available to Noteholders pursuant to Section 11.11(d) since the Closing Date; and (iv) any other information in the possession of the Indenture Trustee that may be necessary to satisfy the requirements of subsection (d)(4)(i) of Rule 144A under the Securities Act. 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) this Indenture and any Indenture Supplement, as amended from time to time; (iv) all Indenture Trustee Reports; and (v) the most recent audited consolidated financial statements of the Issuer, the Asset Entities and GTP Issuer Holdco, LLC; provided, that the Requesting Party furnish to the Indenture Trustee a written certification substantially in the form attached hereto as Exhibit F as to the effect that (x) in the case of a Noteholder, such Person or entity will keep such information confidential (except that any Noteholder may provide any such information obtained by it to any other person or entity that holds or is contemplating the purchase of any Note or interest therein; provided that such other person or entity 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 or entity is a beneficial owner of Notes held in book-entry form and will keep such information confidential (except that such Note Owner may provide such information to any other Person or entity that holds or is contemplating the purchase of any Note or interest therein; provided that such other person or entity 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 or entity 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 will otherwise keep such information confidential.

(d) Based on information provided in the Servicer’s monthly reports (based 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 (“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 will be available to the Note Owners only to the extent that it can be obtained through DTC and the DTC Participants. The manner in which notices and other communications are conveyed by DTC to DTC Participants, and by DTC Participants to the Note Owners, will 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) The Indenture Trustee shall not be liable for providing or disseminating information in accordance with the terms of this Indenture.

119

provided, however, the amendment of the Indenture or any Indenture Supplement will be prohibited unless (i) the Indenture Trustee shall first have received a certificate of an Executive Officer of the Issuer to the effect that such Indenture Supplement does not adversely affect in any material respect the interests of any Noteholder, or (unless the Servicer has consented to such amendment) diminish any rights or remedies or increase any liabilities or obligations of the Servicer hereunder, under the Servicing Agreement or any other Transaction Document, (ii) a Rating Agency Confirmation shall have been received with respect to such amendment and (iii) the Indenture Trustee shall have received an Opinion of Counsel (which opinion may contain similar assumptions and qualifications as are contained in the opinion of counsel with respect to the tax treatment of the Notes delivered on the Initial Closing Date) to the effect that such amendment will not (x) cause any of the Notes to be deemed to have been exchanged for a new debt instrument pursuant to Treasury Regulations §1.1001-3, (y) cause the Issuer to be taxable as other than a partnership or disregarded entity for U.S. federal income tax purposes or (z) cause any of the Notes to be characterized as other than indebtedness for federal income tax purposes.

In addition without the consent of the Noteholders, the Indenture Trustee, when authorized by an Issuer Order, at any time and from time to time, may enter into any amendment (or provide its consent to any amendment) of any other Transaction Document in accordance with the terms of such Transaction Document; provided that either (x) (i) the Indenture Trustee shall first have received a certificate of an Executive Officer of the Issuer to the effect that such amendment does not adversely affect in any material respect the interests of any Noteholder or (unless the Servicer has consented to such amendment) diminish any rights or remedies or increase any liabilities or obligations of the Servicer hereunder, under the Servicing Agreement or any other Transaction Document and (ii) a Rating Agency Confirmation shall have been received with respect to such amendment or (y) the Indenture Trustee shall have received the consent of the Noteholders as and to the same extent such consent would be required for an Indenture Supplement pursuant to Section 13.02 and the consent of the Servicer if the effect of any such amendment would be to diminish any rights or remedies or increase any liabilities or obligations of the Servicer under the Servicing Agreement or any other Transaction Document; provided that any consent by the Indenture Trustee required by the provisions of Section 9(j)(ii) of the limited liability company operating agreement of the Issuer or of the Guarantor shall require the prior direction of Noteholders representing more than 50% of the Voting Rights of all Notes voting as a single class.

Section 13.02 Indenture Supplements with Consent of Noteholders. The Issuer and the Indenture Trustee, when authorized by an Issuer Order, with a prior direction of Noteholders representing more than 50% of the Voting Rights of each Class of Notes adversely affected thereby and without prior notice to any other Noteholder, also may amend, supplement or modify this Indenture, any Indenture Supplement or the Notes or waive compliance by the Issuer with any provision of this Indenture, any Indenture Supplement or the Notes; provided, however, that no such amendment, modification, supplement or waiver may, without the consent of the Holder of each Note affected thereby (including any tax consequences) and with respect to clause (viii) below, without the consent of the Servicer:

(i) change the Anticipated Repayment Date applicable to the Series or the Rated Final Payment Date applicable to the Series;

120

(ii) reduce the amounts required to be paid on the Notes on any Payment Date, the Anticipated Repayment Date or the Rated Final Payment Date;

(x) permit the creation of any lien ranking prior to or on parity with the lien of the Noteholders with respect to the Collateral or, except as otherwise permitted or contemplated in this Indenture or any Indenture Supplement terminate the lien of the Noteholders on such Collateral or deprive the Noteholders of the security afforded by such.

In determining whether a proposed amendment would adversely affect any Class of Notes, the Indenture Trustee may rely conclusively on a certificate of an Executive Officer of the Issuer.

It shall not be necessary for any Act of the Noteholders under this Section 13.02 to approve the particular form of any proposed indenture supplement, but it shall be sufficient if such Act shall approve the substance thereof.

Notwithstanding anything to the contrary in this Section 13.02, an Indenture Supplement entered into for the purpose of issuing Additional Notes the issuance of which complies with the terms of the Indenture shall not require the consent of any Noteholder.

Promptly after the execution by the Issuer and the Indenture Trustee of any indenture supplement pursuant to this Section 13.02, the Indenture Trustee shall mail to the

121

Holders of the Notes and the Servicer a copy of such indenture supplement. Any failure of the Indenture Trustee to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such indenture supplement.

Section 13.03 Execution of Indenture Supplements. In executing, or permitting the additional trusts created by, any indenture supplement permitted by this Article XIII or the modification thereby of the trusts created by this Indenture, the Indenture Trustee shall be entitled to receive, and, subject to Section 11.02, shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such indenture supplement is authorized or permitted by this Indenture and that all conditions precedent to the execution and delivery of such indenture supplement have been satisfied. The Indenture Trustee may, but shall not be obligated to (and with respect to the Servicer shall not, except as permitted by the Servicing Agreement), enter into any such indenture supplement that affects the Indenture Trustee’s (or with respect to the Servicer, the Servicer’s) own rights, duties, liabilities or immunities under this Indenture or otherwise.

Section 13.04 Effect of Indenture Supplement. Upon the execution of any indenture supplement pursuant to the provisions hereof, this Indenture shall be and shall be deemed to be modified and amended in accordance therewith with respect to the Notes affected thereby, and the respective rights, limitations of rights, obligations, duties, liabilities and immunities under this Indenture of the Indenture Trustee, the Servicer, the Issuer and the Holders of the Notes shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such indenture supplement shall be and be deemed to be part of the terms and conditions of this Indenture and any Indenture Supplement for any and all purposes.

Section 13.05 Reference in Notes to Indenture Supplements. Notes authenticated and delivered after the execution of any indenture supplement pursuant to this Article XIII may bear a notation in form approved by the Indenture Trustee as to any matter provided for in such indenture supplement. If the Issuer shall so determine, new Notes so modified as to conform, in the opinion of the Issuer, to any such indenture supplement may be prepared and executed by the Issuer and authenticated and delivered by the Indenture Trustee in exchange for Outstanding Notes.

124

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, Asset Entity, 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 15.02 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 Issuer 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 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 Issuer, stating that the information with respect to such factual matters is in the possession of the Issuer, unless such officer or officers of the Issuer 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 Issuer and/or the Asset Entities shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer’s and/or the Asset Entities’ 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 Issuer and/or the Asset Entities to have such application granted or to the sufficiency of

125

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 15.03 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, where it is hereby expressly required, to the Issuer. 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 and the Issuer, if made in the manner provided in this Section 15.03.

(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 Issuer shall solicit from Noteholders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its 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 Issuer shall have no obligation to do so. Any such record date shall be fixed at the Issuer’s discretion. If not set by the Issuer 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 thirty (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 Issuer in reliance thereon, whether or not notation of such action is made upon such Note.

126

(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 15.04 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 Issuer 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

(ii) the Issuer 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 addressed to: GTP Towers Issuer, LLC, ▇▇▇ ▇▇▇▇ ▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇ ▇. ▇▇▇▇▇ or at any other address previously furnished in writing to the Indenture Trustee and the Servicer by the Issuer. The Issuer 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 Issuer, GTP Issuer Holdco, LLC, or the Asset Entities 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 Issuer and/or the Asset Entities or the Indenture Trustee shall be in writing, personally delivered, faxed, mailed by certified mail, or e-mailed to the following addresses: (i) in the case of Fitch, Inc., to ▇▇▇▇.▇▇▇▇@▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇ (ii) ▇▇▇▇▇’▇ Investors Service, Inc., 7 World Trade Center, at ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ – 24^th Floor, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Monitoring Group.

127

Section 15.05 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.

(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 15.06 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.

All covenants and agreements in this Indenture, any Indenture Supplement and the Notes by the Obligors 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 15.09 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 15.11 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 15.12 Governing Law. THIS INDENTURE AND EACH INDENTURE SUPPLEMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. EACH OBLIGOR IRREVOCABLY SUBMITS 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 15.13 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.

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 covenants and agrees that neither it nor the Indenture Trustee on behalf of such Noteholder will at any time institute against the Issuer and/or the Asset Entities or the Guarantor, or join in any institution against the Issuer and/or the Asset Entities 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 15.17 Extinguishment of Obligations. Notwithstanding anything to the contrary in this Indenture or any Indenture Supplement, all obligations of the Issuer hereunder or under any Indenture Supplement shall be deemed to be extinguished in the event that, at any time, the Issuer, the Guarantor and the Asset Entities have no assets (which shall include claims that may be asserted by the Issuer, the Guarantor and the Asset Entities with respect to contractual obligations of third parties to the Issuer, the Guarantor and the Asset Entities but which shall not include the proceeds of the issue of their shares in respect of the Closing Date). No further claims may be brought against any of the Issuer’s 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 15.18 Inspection. The Issuer agrees that, with reasonable prior notice, Issuer and the Asset Entities will permit any representative of the Indenture Trustee or the Servicer, during the Issuer’s and Asset Entities’ normal business hours, to examine all the books of account, records, reports and other papers of the Issuer and the Asset Entities, to make copies and extracts therefrom, to cause such books to be audited by Independent certified public accountants, and that the Issuer and the Asset Entities will 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.

Nothing contained in this Indenture or any other Transaction Document shall prohibit Holdings or any subsidiary or Affiliate of Holdings (other than the Guarantor or an Obligor) from owning and managing wireless communications towers that are not Tower Sites and are consequently not included as Collateral (such sites, “Excluded Tower Sites”). If Excluded Tower Sites are acquired after the Initial Closing Date by Holdings or a non-Asset Entity subsidiary or non-Obligor subsidiary and such entity proposes to enter into a lease of the related site space with a party that is also a Tenant under a Tenant Lease, such new lease will be separate from and independent of any Tenant Lease between such party and an Asset Entity.

Section 15.20 Waiver of Immunities. To the extent that the Issuer has 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 Issuer hereby irrevocably waives 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.

130

Section 15.21 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 Issuer (other than the Collateral) or against the Indenture Trustee, the Servicer or any Agents or Affiliates thereof.

Section 15.22 Indenture Trustee’s Duties and Obligations Limited. The duties and obligations of Indenture Trustee, in its various capacities hereunder and under any Indenture Supplement, shall be limited to those expressly provided for in 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 15.23 Appointment of Servicer. The Issuer hereby consents to the appointment of Midland Loan Services, Inc. to act as Servicer.

Section 15.24 Agreed Upon Tax Treatment. By purchasing the Notes, each Holder will agree to treat the Notes as debt for all United States tax purposes.

Section 15.25 Existing Security Interests. For purposes of clarity, the security interests granted to the Indenture Trustee under the Existing Indenture are hereby confirmed and deemed to continue uninterrupted under this Indenture; provided that, the Parent Guarantee, the Subsidiary Guarantee, the Security Agreement and the Pledge Agreement (as such terms are defined in the Existing Indenture) will terminate on the Initial Closing Date. The parties hereto authorize and direct the Indenture Trustee to enter into the Global Assignment and Acceptance Agreement in order that the Indenture Trustee for the benefit of the Noteholders under this Indenture shall purchase all the right, title and interest in the advances made by the financial institutions under the Existing Indenture and that such advances shall be deemed to be and shall be converted into the Notes under this Indenture. The acquisition of such advances shall be funded by the Issuer with the net proceeds of the issuance of the Notes hereunder, together with other proceeds otherwise available to the Issuer. By accepting the Notes hereunder, the Noteholders shall be deemed to have agreed to the terms and conditions of the Global Assignment and Acceptance Agreement.

Section 15.26 Tax Forms. The Holder by its acceptance of its Note, agrees that it shall timely furnish the Issuer or its agents any U.S. federal income tax form or certification (such as IRS Form W-8BEN (Certification of Foreign Status of as Beneficial Owner), Form W-8IMY (Certification of Foreign Intermediary Status), IRS Form W-9 (Request for Taxpayer Identification Number and Certification), or IRS Form W-8ECI (Certification of Foreign Person’s Claim for Exemption from Withholding on Income Effectively Connected with Conduct of a U.S. Trade or Business) or any successors to such IRS forms) that the Issuer or its

131

agents may reasonably request and shall update or replace such form or certification in accordance with its terms or its subsequent amendments. It agrees to provide any certification or information that is reasonably requested by the Issuer or its agents (a) to permit the Issuer to make payments to it without, or at a reduced rate of, withholding, (b) to enable the Issuer to qualify for a reduced rate of withholding in any jurisdiction from or through which the Issuer receives payments on its assets, or (c) to determine and/or satisfy its duties and liabilities with respect to any taxes or other charges that it may be required to pay, deduct or withhold from payments in respect of the Notes or the holder of such Notes under any present or future law or regulation by any jurisdiction or taxing authority therein or to comply with any reporting or other requirements under any law or regulation.

ARTICLE XVI

GUARANTEES

Section 16.01 Guarantees. Each Asset Entity hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Indenture Trustee and the Servicer and their respective successors and assigns (a) the full and punctual payment of principal of and interest on the Notes when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Issuer and the other Asset Entities under this Indenture and the Notes and each other Transaction Document and (b) the full and punctual performance within applicable grace periods of all other obligations of the Issuer and the other Asset Entities under this Indenture and the Notes and all other Transaction Documents (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).

Each Asset Entity waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Asset Entity waives notice of any default under the Notes or the other Guaranteed Obligations. The obligations of each Asset Entity hereunder shall not be affected by (a) the failure of any Holder or the Indenture Trustee or the Servicer to assert any claim or demand or to enforce any right or remedy under the Transaction Documents against any other Obligor or any other Person or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other Transaction Document; (d) the release of any security held by any Holder or the Indenture Trustee for the Obligations or any of them; or (e) the failure of any Holder or the Indenture Trustee or the Servicer to exercise any right or remedy against any other guarantor of the Guaranteed Obligations.

Each Asset Entity further agrees that its guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Indenture Trustee or the Servicer to any security held for payment of the Guaranteed Obligations.

Except as expressly set forth herein, the obligations of each Asset Entity hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not

132

be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Asset Entity herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Indenture Trustee or the Servicer to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Asset Entity or would otherwise operate as a discharge of such Asset Entity as a matter of law or equity.

Each Asset Entity further agrees that its guaranty herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Indenture Trustee or the Servicer upon the bankruptcy or reorganization of the Issuer or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Indenture Trustee or the Servicer has at law or in equity against any Asset Entity by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Asset Entity hereby promises to and will, upon receipt of written demand by the Indenture Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee or the Servicer, as the case may be, an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Obligations and (iii) all other monetary Guaranteed Obligations of the Issuer to the Holders and the Indenture Trustee and the Servicer.

Each Asset Entity also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Indenture Trustee or the Servicer in enforcing any rights under this Section.

Notwithstanding any payment made by any Asset Entity hereunder, such Asset Entity shall not be entitled to be subrogated to any of the rights of the Indenture Trustee against the Obligors or any collateral security or guarantee or right of offset held by the Indenture Trustee for the payment of the Obligations, nor shall the Asset Entity seek or be entitled to seek any contribution or reimbursement from the Obligors in respect of payments made by the Asset Entity hereunder, until the Obligations are paid in full. If any amount shall be paid to an Asset Entity on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Asset Entity in trust for the Indenture Trustee, segregated from other funds of such Asset Entity, and shall, forthwith upon receipt by such Asset Entity, be turned over to the Indenture Trustee in the exact form received by such Asset Entity (duly indorsed by such Asset Entity to the Indenture Trustee, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Indenture Trustee may determine.

133

Section 16.02 Limitation on Liability. Any term or provision of this Indenture to the contrary, the maximum, aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Asset Entity shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Asset Entity, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 16.03 Successors and Assigns. Subject to Section 16.06, this Article XVI shall be binding upon each Asset Entity and its successors and assigns and shall inure to the benefit of the successors and assigns of the Indenture Trustee, the Servicer and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Indenture Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 16.04 No Waiver. Neither a failure nor a delay on the part of either the Indenture Trustee, the Servicer or the Holders in exercising any right, power or privilege under this Article XVI shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Indenture Trustee, the Servicer and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article XVI at law, in equity, by statute or otherwise.

Section 16.05 Modification. No modification, amendment or waiver of any provision of this Article XVI, nor the consent to any departure by any Asset Entity therefrom, shall in any event be effective unless the same shall be in writing and signed by the Indenture Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Asset Entity in any case shall entitle such Asset Entity to any other or further notice or demand in the same, similar or other circumstances.

Section 16.06 Release of Asset Entity. Upon the sale or other disposition (including by way of consolidation or merger) of an Asset Entity that is permitted hereunder (each case other than to the Issuer or another Asset Entity), such Asset Entity shall be deemed released from all obligations under this Article XVI without any further action required on the part of the Indenture Trustee or any Holder. At the request of the Issuer, the Indenture Trustee shall execute and deliver an appropriate instrument evidencing such release.
