(c) No transfer of any Note or interest therein shall be made (A) to any retirement plan or other employee benefit plan, including individual retirement accounts and annuities, Keogh plans and collective investment funds, insurance company separate accounts and certain insurance company general accounts in which such plans, accounts or arrangements are invested, that is subject to Section 406 of Title I of ERISA, or Section 4975 of the Code or any substantially similar provision of any federal, state, or local law (each, a “ Plan ”), or (B) to any Person who is directly or indirectly acquiring such Note or such interest therein on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan, if the acquisition and holding of such Note or interest therein by the prospective Transferee would result in a violation of Section 406 of ERISA or Section 4975 of the Code or would result in a civil penalty under ERISA or in the imposition of an excise tax under Section 4975 of the Code. No transfer of any Note shall be made to any Plan (which for purposes of this sentence shall include any employee benefit plan or other retirement arrangement subject to any federal, state or local law which is, to a material extent, similar to Section 406 of ERISA or Section 4975 of the Code) or to any person who is directly or indirectly acquiring such Note on behalf of, as fiduciary of, as trustee of, or with the assets of, a Plan, unless the purchase and holding of such note or interest therein by such Plan or person are exempt from the prohibited transaction restrictions of ERISA and the Code or materially similar provisions under similar law pursuant to one or more prohibited transaction statutory or administrative exemptions. Any attempted or purported transfer of a Note in violation of this Section 2.02(c) 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 either:

(i) a certification or deemed representation, as applicable, to the effect that such prospective Transferee is not a Plan and is not directly or indirectly acquiring such Note on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan (which shall include for purposes of this clause (i) any employee benefit plan or other retirement arrangement subject to any federal, state, or local law which is, to a material extent, similar to Section 406 of ERISA or Section 4975 of the Code); or

-38-

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

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

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

(i) a certification or deemed representation, as applicable, to the effect that such prospective Transferee is not a Plan and is not directly or indirectly acquiring such interest in such Note on behalf of, as fiduciary of, as trustee of, or with assets of, a Plan (which shall include for purposes of this clause (i) any employee benefit plan or other retirement arrangement subject to any federal, state or local law which is, to a material extent, similar to Section 406 of ERISA or Section 4975 of the Code); or

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

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

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

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

-39-

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

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

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

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

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

-40-

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

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

Section 2.04 Mutilated, Destroyed, Lost or Stolen Notes . If (i) any mutilated Note is surrendered to the Note Registrar, or the Note Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the 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 like Percentage Interest shall be executed, authenticated and delivered in accordance with Section 2.01(b). Upon the issuance of any new Note under this Section 2.04, the 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.

-41-

Section 2.05 Persons Deemed Owners . Prior to due presentment for registration of transfer, the Issuers, the Servicer, the Indenture Trustee and any agent of any of them may treat the Person in whose name any Note is registered as the owner of such Note for the purpose of receiving payments pursuant to Article V herein and for all other purposes whatsoever, and none of the Issuers, 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 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 Issuable in Series The Notes of the Issuers may be issued in one or more Series. There shall be established in one or more Indenture 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 all other Notes);

(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);

(v) any other terms of such Series (which terms shall not be inconsistent with the provisions of this Indenture).

All Notes of a particular Series may have more than one settlement or issue date, but will otherwise have identical terms. The Notes of each Series will be limited or non-recourse obligations of the Issuers, ranking pari passu with, and rated the same as, a Class of Notes, and will have the same or later Anticipated Repayment Date as a Class of Notes, previously issued under this Indenture, except in the case where the related Indenture Supplement provides otherwise.

Section 2.08 Principal Amortization . Prior to the Anticipated Repayment Date, unless an Amortization Period commences or as otherwise provided in Section 7.06, no principal shall be required to be paid with respect to any Class of Notes.

From and after the second (2nd) anniversary of the Closing Date, the Issuers may prepay the Notes in whole or in part on any Payment Date provided that such prepayment is accompanied by the applicable Prepayment Consideration if such prepayment occurs more than three (3) months prior to the Anticipated Repayment Date. All prepayments made in conformity with the provisions of this Section 2.09 will be applied at the Issuer Entity’s option either (y) with respect to all Classes of Notes of all Series, first to reduce the aggregate Class Principal Balance of the Class A-FX Notes and the Class A-FL Notes, pro rata based on the Note Principal Balance of each such Note, until the aggregate of the Class Principal Balance of the Class A-FX Notes and the Class A-FL Notes is reduced to zero, next to reduce the Class Principal Balance of the Class B Notes, pro rata based on the Note Principal Balance of each such Note, until the Class Principal Balance of the Class B Notes is reduced to zero, next to reduce the Class Principal Balance of the Class C Notes, pro rata based on the Note Principal Balance of each such Note, until the Class Principal Balance of the Class C Notes is reduced to zero, next to reduce the Class Principal Balance of the Class D Notes, pro rata based on the Note Principal Balance of each such Note, until the Class Principal Balance of the Class D Notes is reduced to

(b) In connection with each disposition of a Tower Site as contemplated in Section 7.32 herein, the Issuers 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 Fees and 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 occurs more than three (3) months prior to the Anticipated Repayment Date; provided , however , that the Issuers shall not be required to pay any Release Price (other than amounts then due and owing to the Indenture Trustee and Servicer hereunder and under the other Transaction Documents) or Prepayment Consideration in respect of a disposition or dispositions of Tower Sites by the Asset Entities, in any twelve (12) month period, having an aggregate Allocated Note Amount less than or equal to $20,000,000 provided that (1) the proceeds from such disposition or dispositions of such Tower Sites is an amount greater than or equal to 125% of the Allocated Note Amount of such Tower Sites, (2) the applicable Asset Entity delivers a notice that the net cash proceeds of any such disposition will be deposited into an account with the Indenture Trustee (the “ Liquidated Tower Replacement Account ”) and within 6 months will be used by an Asset Entity to acquire Tower Sites and (3) the DSCR following such disposition is greater than or equal to the DSCR immediately prior to such disposition after giving pro forma effect to the receipt of proceeds in connection therewith. 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 of clauses (ii) through (vii) of Section 7.33, as if the acquired Tower Sites were Replacement Tower Sites. Any funds remaining in the Liquidated Tower Replacement Account after six (6) months from the date of initial deposit shall be withdrawn by the Indenture Trustee and used, 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.

Section 2.10 Post-ARD Additional Interest . Additional interest (the “ Post-ARD Additional Interest ”) shall begin to accrue from and after the Anticipated Repayment Date on the Class Principal Balance of each Class of Notes 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) five percent (5%) and (ii) the amount, if any, by which the sum of the following exceeds the Note Rate for such Class of Fixed Rate Notes: (A) the yield to maturity (adjusted to a “mortgage equivalent basis” pursuant to the standards and practices of the Securities Industry Association) on the Anticipated Repayment Date of the United States Treasury Security having a term closest to ten (10) years plus (B) five percent (5%), plus (C) the Post-ARD Note Spread for such Class of Fixed Rate Notes.

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 three (3) months prior to the Anticipated Repayment Date, the Issuers may (upon thirty (30) days’ written notice to the Indenture Trustee) obtain the release from all covenants under this Indenture relating to ownership and operation of the Tower Sites by defeasing all of the Notes then outstanding with U.S. government securities that provide for payments which replicate the required payments on such Class of Notes (including interest on the Class A-FL of each Series Notes computed at, and determined in accordance with, the Class A-FX Note Rate for such Series) and the Indenture Trustee Fees and Workout Fees, if any, through the Anticipated Repayment Date (including payment in full of the principal of such Class of Notes on the Anticipated Repayment Date), provided , that (i) no Event of Default has occurred and is continuing and (ii) the Issuers 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 Issuers shall deliver to the Servicer on behalf of the Indenture Trustee, (1) a security agreement granting the Indenture Trustee a first priority perfected lien on the U.S. government securities so delivered by the Issuers, (2) an opinion of

-45-

counsel as to the enforceability and perfection of such lien, (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 (including interest on the Class A-FL Notes of each Series computed at, and determined on the same basis as, the Class A-FX Note Rate for such Series) and all principal due upon maturity for each Class of Notes, and all Indenture Trustee Fees and Workout Fees, if any, and (4) a Rating Agency Confirmation.

(d) On each Payment Date, based on the report by the Servicer showing the amount to be paid into the Floating Rate Account, the Indenture Trustee will apply the funds in the Floating Rate Account (i) to the payment of its obligations to the Swap Counterparty in accordance with the terms of the Swap Contract, to the payment of any Prepayment Consideration, or to the payment of a portion of any Post-ARD Additional Interest or Deferred Post-ARD Additional Interest as provided in Section 2.10 hereof, in each case then payable to the Swap Counterparty, or to the swap counterparty of any replacement swap contract, and (ii) to the Holders of the Class A-FL Notes as of the related Record Date in the following amounts, pro rata based on the Note Principal Balance of the Class A-FL Notes, (A) to the payment of up to an amount equal to all Accrued Note Interest in respect of the interest due to the Holders of the Class A-FL Notes on such Payment Date and, to the extent not previously paid, from all prior Payment Dates; (B) in the event of the termination of the Swap Contract and the failure of the Swap Counterparty to replace the Swap Contract, to the payment of the amounts remaining from any termination payments paid by the Swap Counterparty not otherwise used to offset the expense of entering into a replacement swap contract, (C) to the payment of all or a portion of any Post-ARD Additional Interest or Deferred Post-ARD Additional Interest as provided in Section 2.10 hereof, and (D) to the payment of any Prepayment Consideration, if the Swap Contract and any replacement swap contract has been terminated.

(f) The Indenture Trustee has no obligation to pay or cause to be paid to the Swap Counterparty any of the payments due under the Swap Contract except to the extent the amounts therefore are actually received by the Indenture Trustee and deposited into the Floating Rate Account.

Section 4.01 Security Interest in Reserves; Other Matters Pertaining to Reserves . (a) The Issuers hereby pledge, assign and grant to the Indenture Trustee a security interest in and to all of the Issuers’ right, title and interest in and to the Account Collateral, including the Reserves, as security for payment and performance of all of the Obligations hereunder and under the other Transaction Documents. The Reserves constitute Account Collateral and are subject to the security interest in favor of Indenture Trustee created herein and all provisions of this Indenture and the other Transaction Documents pertaining to Account Collateral.

The initial amount of the monthly deposit to be made to the Impositions and Insurance Reserve from and after the date hereof is $2,042,259 . 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 Issuers shall deposit with the Collection Account Bank within ten (10) Business Days of a written demand by Indenture Trustee, to be added to and included within such Reserve, a sum of money which the Servicer has determined (in reliance on the Manager’s written request), together with such monthly deposits, 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 Issuer Entity shall cause the Asset Entities to 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 Asset Entities have provided the Indenture Trustee and the Servicer with the foregoing materials in a timely manner, and (iii) sufficient funds are held by the Indenture Trustee for the payment of the Impositions and Insurance Premiums relating to the Tower Sites, as applicable, the Indenture Trustee shall, at the Manager’s election and written direction, with written notice simultaneously delivered to the Servicer, (x) pay said items, (y) disburse to the Asset Entities from such Reserve an amount sufficient to pay said items, or (z) reimburse the Asset Entities for items previously paid by the Asset Entities.

The Targeted Environmental Reserve Sub-Account Balance will increase in equal monthly installments so that on the date that is twelve (12) months from the Closing Date, the Targeted Environmental Reserve Sub-Account Balance will be $5,000,000. During the continuation of a Cash Trap Condition, the Targeted Environmental Reserve Sub-Account Balance will increase to $10,000,000, unless the Issuers provide to the Indenture Trustee an environmental insurance policy from a nationally recognized insurance company satisfactory to the Servicer providing for coverage in an amount that, together with monies held in the Environmental Remediation Reserve Sub-Account, is at least equal to the Targeted Environmental Reserve Sub-Account Balance. Funds in the Environmental Reserve Sub-Account may be withdrawn by the Servicer to pay the cost of environmental remediation services obtained by the Servicer, acting in accordance with the Servicing Standard, when the Asset Entities have failed to remediate environmental conditions at any of the Tower Sites.

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 Excess Cash Flow (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 ”). During the continuation of an Amortization Period, or on or after the Anticipated Repayment Date, the Indenture Trustee will apply all funds deposited in the Cash Trap Reserve Sub-Account on any Payment Date 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 to payment of the Outstanding principal on the Notes on such Payment Date (including any required Yield Maintenance). Any such repayment shall be applied first 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

-52-

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), second, to reduce the Class Principal Balance of the Class of Notes outstanding having the earliest alphabetical designation until the Class Principal Balance of such Class is reduced to zero, and then to reduce the Class Principal Balance of the Class of Notes outstanding having the second earliest alphabetical designation and so on until the Class Principal Balances of all Classes of Notes have been reduced to zero. For such purposes, the Class A-FL Notes will be deemed to have the same alphabetical designation as the Class A-FX Notes and will be pari passu with the Class A-FX Notes. Prior to the Anticipated Repayment Date, if a Cash Trap Condition ceases to exist and no Event of Default has occurred and is continuing, any funds then on deposit in the Cash Trap Reserve Sub-Account shall be released to the Issuer Entity. Prior to the Anticipated Repayment Date, if a Cash Trap Condition is continuing and the DSCR is greater than or equal to 1.75 to 1.0, and no Event of Default has occurred and is continuing, funds in the Cash Trap Reserve shall be released to the Issuer Entity to be used solely to meet the debt service requirements of Crown International and its subsidiaries (other than CC Towers Holding and its subsidiaries). The existence of a Cash Trap Condition shall be determined by the Servicer in its reasonable good faith determination which may be based solely upon the Financial Statements received by the Servicer. Notwithstanding any provision herein to the contrary, during the continuance of an Event of Default all funds on deposit in the Cash Trap Reserve and any subsequent Excess Cash Flow may be applied by the Indenture Trustee (solely at the direction and discretion of the Servicer) to payment of the Notes (including payment of Yield Maintenance, if any) or other Obligations as the Servicer may elect.

Section 7.05 Maintenance of Insurance . The Issuer Entity shall cause the Asset Entities to continuously maintain the following described policies of insurance without cost to the Indenture Trustee or the Servicer (the “ Insurance Policies ”):

(i) Property insurance against loss and damage by all risks of physical loss or damage and other risks covered by the so-called extended coverage endorsement covering the Improvements and personal property on each of the Tower Sites owned by any of the Asset Entities, in amounts not less than the full insurable replacement value of all Improvements (less building foundations and footings) and personal property from time to time on the Tower Sites and without sublimits, and bearing a replacement cost agreed-amount endorsement;

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

-73-

(iv) An umbrella excess liability policy with a limit of not less than Twenty-Five Million Dollars ($25,000,000) over any underlying primary commercial general liability and automobile liability;

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

(vi) Such other insurance as may from time to time be reasonably required by the Servicer and which is then customarily required by institutional lenders for securitized loans secured by similar properties similarly situated, against other insurable hazards, including, but not limited to, malicious mischief, vandalism, windstorm, due regard to be given to the size and type of the Tower Sites, Improvements, fixtures and equipment and their location, construction and use.

All Insurance Policies shall be in content (including, without limitation, endorsements or exclusions, if any) and, form reasonably satisfactory to the Servicer from time to time and, to the extent permissible, shall name the Indenture Trustee and its successors and assignees as their interests may appear as an “additional loss payee” for each of the liability, property and casualty policies under this Section 7.05 and shall contain a waiver of subrogation clause reasonably acceptable to the Servicer. 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 Asset Entities may obtain any insurance required by this Section 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. 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, flood, and earthquake insurance. The Issuer Entity shall on the Closing Date and thereafter, within 120 days following the end of each calendar year, deliver valid evidence of property insurance in the form of ACORD form 28, Evidence of Insurance, or a comparable certificate of insurance affirming: the issuance of the policies of insurance required by this Indenture, that the insurance coverage meets all of the requirements set forth in this Indenture and that the required policies are in full force and effect.

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 Entity shall cause the Asset Entities to obtain and deliver to the Servicer a Rating Agency Confirmation with respect to such carrier from each of the Rating Agencies. If any insurance coverage required under this Section 7.05 is maintained by a syndicate of insurers, the preceding ratings requirements shall be deemed satisfied (without any required Rating Agency Confirmation) as long as at least seventy-five percent (75%) of the coverage (if there are four or fewer members of the syndicate) or at least

-74-

sixty percent (60%) of the coverage (if there are five or more members of the syndicate) is maintained with carriers meeting the claims-paying ability ratings requirements set forth above and all carriers in such syndicate have a claims-paying ability rating by Moody’s of not less than “Baa2” (to the extent rated by Moody’s). The Issuer Entity shall cause the Asset Entities to 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 Asset Entities concurrent in form or contributing in the event of loss with the Insurance Policies. Losses in excess of $1,000,000 shall be payable to the Indenture Trustee notwithstanding (1) any act, failure to act or negligence of the Asset Entities 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 Entity or the Manager, without any obligation to investigate the accuracy or completeness of any information set forth therein, and shall have no liability with respect thereto.

Section 7.06 Operation and Maintenance of the Tower Sites; Casualty; Condemnation . (a) The Issuer Entity 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.

(b) (i) In the event of casualty or loss at any of the Tower Sites, the Issuer Entity shall cause the Asset Entities to give prompt written notice, and in any event within three (3) Business Days, 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 Entity 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 Insurance and Impositions 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

-75-

incurred in the collection of such proceeds; provided however, that nothing contained in this Section shall require the Indenture Trustee or the Servicer to incur any expense or take any action hereunder. The Issuer Entity further authorizes the Indenture Trustee, at the Servicer’s option and direction, with respect to 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) subject to Section 7.06(c), to apply such Insurance Proceeds to payment of the Obligations whether or not then due; provided , however , that any such payments on the Notes and other Obligations owed to the Indenture Trustee and the Servicer will be made in accordance with the provisions of Article V of this Indenture.

(ii) The Issuer Entity shall cause the Asset Entities to promptly, and in any event within three (3) Business Days, 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. The Issuer Entity hereby irrevocably appoints the Servicer as the 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 Condemnation Proceeds in excess of $1,000,000 to collect, receive and retain any Condemnation Proceeds (to be held in the Insurance and Impositions 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 Entity 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. Except as provided for in the previous sentence, the Issuer Entity authorizes the Servicer and the Indenture Trustee to apply such Condemnation Proceeds, after the deduction of the Indenture Trustee’s and the Servicer’s reasonable expenses incurred in the collection of such Condemnation Proceeds, at the Servicer’s option and direction, (i) to restoration or repair of the Tower Sites or (ii) to payment on the Notes, whether or not then due (provided that the Indenture Trustee shall not exercise the option in this clause (ii) to apply such Condemnation Proceeds to payment of the Obligations if each of the conditions (as applicable) to the release of Loss Proceeds for restoration or repair of the Tower Sites under Section 7.06(c) below have been satisfied with respect to such condemnation awards or damages), with the balance, if any, to the Asset Entities; provided , however , that any such payments on the Notes and other Obligations owed to the Indenture Trustee and the Servicer will be

-76-

made in accordance with the provisions of Article V of this Indenture. Application of any Condemnation Proceeds to payment of the Obligations pursuant to the foregoing sentence shall be made with the required Prepayment Consideration.

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 Indenture. Notwithstanding the foregoing to the contrary, the Asset Entities may, in their 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 such Loss Proceeds held in the Insurance and Impositions Reserve Sub-Account with respect to such Tower Site shall be applied to 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 due to the Servicer and the Indenture Trustee hereunder and under the other Transaction Documents, and any other amounts due and payable pursuant to Section 3.03 hereof), and second , prepayment of the Notes, including the applicable Prepayment Consideration on the Payment Date immediately following such election.

(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. Any amount of Loss Proceeds remaining in the Indenture Trustee’s possession after full and final payment and discharge of all Obligations shall be refunded to, or as directed by, the Asset Entities or otherwise paid in accordance with applicable law. If a Tower Site is sold at foreclosure or if the Indenture Trustee acquires title to a Tower Site, the Indenture Trustee shall have all of the right, title and interest of the applicable 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 Asset Entities, less a retainage equal to the greater of (x) the actual retainage required pursuant to the permitted contract, or (y) ten percent (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

-77-

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.

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 Asset Entity, 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 Asset Entity’s offices.

(f) Bankruptcy .

(i) If any Ground Lessor shall reject any Ground Lease under or pursuant to Section 365 of the Bankruptcy Code, the Issuer Entity shall not permit the applicable

-89-

Asset Entities to elect to treat the Ground Lease as terminated but, rather, shall cause such Asset Entities to elect to remain in possession of the applicable Ground Lease Tower Site and the leasehold estate under such Ground Lease.

(ii) The Issuer Entity acknowledges and agrees that in any case commenced by or against the Asset Entities under the Bankruptcy Code, the Indenture Trustee by reason of the liens and rights granted under the Transaction Documents shall have a substantial and material interest in the treatment and preservation of such Asset Entities’ rights and obligations under such Ground Leases, and to cause such Asset Entities to, in any such bankruptcy case, provide to the Indenture Trustee immediate and continuous reasonably adequate protection of such interests. The Issuer 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 Entities’ 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 Tower Site.

(B) The Issuer Entity shall cause the Asset Entities to 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 Tower Site. The Issuer Entity shall cause (i) each Asset Entity to 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 any 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, the Issuer Entity shall cause the Asset Entity to assume the Ground Lease, and to 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 Entities 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 the Issuer Entity shall cause the Asset Entities to 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, then the Issuer Entity shall cause the Asset Entities

-90-

to, subject to applicable law, continue any request to reject the Ground Lease until after the motion to assume and assign has been heard. If the Indenture Trustee shall not elect (which shall be at the Servicer’s direction) to assume and assign the Ground Lease, then the Issuer 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.

The Issuer Entity shall cause each Asset Entity 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.

The Issuer Entity shall cause each Asset Entity to appoint 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.

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 any of the Asset Entities may act as Controlling Class Representative.

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.

-107-

(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.

Notwithstanding the foregoing, if a claim is made against the Controlling Class Representative by an Asset Entity 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 (5 ^th ) 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

-108-

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 Entity or any of the Asset Entities (including by way of foreclosure on the equity interests of the Issuer Entity 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 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.

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.

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 .

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

-114-

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 an Issuer) in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees, against any party litigant (other than an Issuer) in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant (other than an Issuer); but the provisions of this Section 10.16 as may be modified by any Indenture Supplement shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of Noteholders, representing more than 10% of the Outstanding Class Principal Balance of all Classes of Notes or (c) any suit instituted by any Noteholder for the enforcement of the payment of the principal balance of any Note or interest on any Note on or after the respective due dates expressed in such Note and in this Indenture or any Indenture Supplement.

Section 10.17 Waiver of Stay or Extension Laws . The Issuers covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, or plead or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, any Indenture Supplement or any Transaction Document; and the Issuers (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not hinder, delay or impede the execution of any power granted in this Indenture to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

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

Section 10.19 Waiver . The Issuers hereby expressly waive, to the fullest extent permitted by law, presentment, demand, protest or any notice of any kind in connection with this Indenture or the Collateral. The Issuers acknowledge and agree that 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 Issuers within the meaning of the UCC.

Section 10.20 Enforcement of Swap Contract . Upon a Swap Default and the expiration of the applicable grace period under the Swap Contract, the Indenture Trustee, unless otherwise directed in writing by the holders of at least 25% of the Outstanding Class Principal Balance of the Class A-FL Notes, shall enforce its rights under the Swap Contract, as may be permitted by the terms thereof, on behalf of the Class A-FL Noteholders and shall use any termination payments received from the Swap Counterparty to enter into a replacement interest rate swap contract on substantially identical terms. The costs and expenses incurred by the

-115-

Indenture Trustee in connection with enforcing the rights of the Indenture Trustee under the Swap Contract will be reimbursable to the Indenture Trustee solely out of amounts on deposit in the Floating Rate Account, to the extent not reimbursed by the Swap Counterparty. If the costs attributable to entering into a replacement interest rate swap contract would exceed the net proceeds of the liquidation of the Swap Contract, the Indenture Trustee will not be required to enter into a replacement interest rate swap contract and any such proceeds will instead be distributed to the holders of the Class A-FL Notes.

In the absence of receipt of such notice or actual knowledge, the Indenture Trustee may conclusively assume that there is no Event of Default.

(vi) Subject to the other provisions of this Indenture, and without limiting the generality of this Section 11.01, the Indenture Trustee shall not have any duty, except as expressly provided herein or in any Indenture Supplement, or in its capacity as successor servicer, (A) to cause any recording, filing, or depositing of this Indenture or any Indenture Supplement or any agreement referred to herein or therein or any financing statement or continuation statement evidencing a security interest, or to cause the maintenance of any such recording or filing or depositing or to any rerecording, refiling or redepositing of any thereof, (B) to see to or cause the maintenance of any insurance, (C) to confirm or verify the truth, accuracy or contents of any reports or certificates of the Issuer Entity, the Asset Entities, Crown International, the Servicer, any Noteholder or Note Owner or any Rating Agency, delivered to the Indenture Trustee pursuant to this Indenture reasonably believed by the Indenture Trustee to be genuine and without error

-117-

(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.
