acquisition of assets that would have required an adjustment pursuant to clause (i),
(ii) or (iii) above if made by the Company or a Restricted Subsidiary during such
period, EBITDA and Indebtedness for such period will be calculated after giving pro
forma effect thereto as if such transaction occurred on the first day of such
period.

the pro forma calculations shall be (x) made in good faith by a responsible financial or accounting
officer of the Company (and may include, for the avoidance of doubt, cost savings and operating

Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by
a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in
such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation
referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro
forma basis shall be computed based upon the average daily balance of such Indebtedness during the
applicable period. Interest on Indebtedness that may optionally be determined at an interest rate

rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based
upon such optional rate chosen as the Issuer may designate.

under Section 1010 (a)(C)(1), the Net Income for such period of any Restricted Subsidiary
(other than any Subsidiary Guarantor) shall be excluded if the declaration or payment of
dividends or similar distributions by that Restricted Subsidiary of its Net Income is not at
the date of determination wholly permitted without any prior governmental approval (which
has not been obtained) or, directly or indirectly, by the operation of the terms of its
charter or any agreement, instrument, judgment, decree, order, statute, rule, or
governmental regulation applicable to such Restricted Subsidiary or its stockholders, unless
such restriction with respect to the payment of dividends or in similar distributions has
been legally waived; provided that Consolidated Net Income of the Company shall be increased

(or to the extent converted into cash) to the Issuer or a Restricted Subsidiary thereof in
respect of such period, to the extent not already included therein,

     (7) the effects of adjustments resulting from the application of purchase accounting in
relation to any acquisition, net of taxes, shall be excluded,

     (8) any net after-tax income (loss) from the early extinguishment of Indebtedness or
Hedging Obligations or other derivative instruments shall be excluded,

     (9) any impairment charge or asset write-off pursuant to Financial Accounting Standards
Board Statement No. 142 and No. 144 and the amortization of intangibles arising pursuant to
No. 141 shall be excluded,

     (10) the amount of any expense will be excluded to the extent a corresponding amount is
received in cash by the Issuer and the Restricted Subsidiaries from a Person other than the
Issuer or any Restricted Subsidiaries under any agreement providing for reimbursement of any
such expense, provided such reimbursement payment has not been included in determining
Consolidated Net Income (it being understood that if the amounts received in cash under any
such agreement in any period exceed the amount of expense in respect of such period, such
excess amounts received may be carried forward and applied against expense in future
periods); and

     (11) any non-cash compensation expense recorded from grants of stock appreciation or
similar rights, stock options or other rights to officers, directors or employees shall be
excluded.

Restricted Subsidiaries, any repayments of loans and advances which constitute Restricted
Investments by the Issuer or any Restricted Subsidiary, any sale of the stock of an Unrestricted

or covenant has been complied with.

     SECTION 103. Form of Documents Delivered to Trustee.

     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

-33-

 

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

          Any certificate or opinion of an officer of the Escrow Issuer, the Company or Finance Co, as
applicable, may be based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, 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 his certificate or opinion is based are erroneous. Any such certificate or opinion may be

of the Escrow Issuer, the Company or Finance Co, as applicable, unless such counsel knows, or in

with respect to such matters are erroneous.

          Where any Person is required to make, give or execute two or more applications, requests,
consents, certificates, statements, opinions or other instruments under this Indenture, they may,

          (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by agents
duly appointed in writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders 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 and conclusive in
favor of the Trustee and the Issuer, if made in the manner provided in this Section.

          (b) The fact and date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a notary public or
other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to him the execution thereof. Where such execution
is by a signer acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of authority. The fact and date of the execution
of any such instrument or writing, or the authority of the Person executing the same, may also be
proved in any other manner that the Trustee deems sufficient.

          (c) The principal amount and serial numbers of Notes held by any Person, and the date of
holding the same, shall be proved by the Note Register.

          (d) If the Issuer shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a
Board Resolution, fix in advance a record date for the determination of Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Issuer shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date
shall be the record date specified in or pursuant to such Board Resolution, which shall be a date
not earlier than the date 30 days prior to the first solicitation of Holders generally in
connection therewith and not later than the date such solicitation is completed. If such a record
date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act
may be given before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of Outstanding Notes have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Notes shall be computed as of such record date; provided that no such
authorization,

-34-

 

agreement or consent by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than eleven
months after the record date. Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and
the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor
or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the
Issuer or any Subsidiary Guarantor in reliance thereon, whether or not notation of such action is
made upon such Note.

          SECTION 105. Notices, Etc., to Trustee, Issuer, Any Subsidiary Guarantor and Agent.

          Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or furnished to, or
filed with,

     (1) the Trustee by any Holder or by the Issuer or any Subsidiary Guarantor shall be
sufficient for every purpose hereunder if made, given, furnished or filed in writing (which
may be via facsimile) to or
with the Trustee at Wilmington Trust FSB, Corporate Capital Markets, 50 South Sixth
Street, Suite 1290, Minneapolis, MN 55402-1544, Fax (612) 217-5651, Attention: Clearwater
Communications LLC Administrator, or

     (2) the Issuer or any Subsidiary Guarantor by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if made,
given, furnished or delivered in writing and mailed, first-class postage prepaid, or
delivered by recognized overnight courier, to the Issuer or such Subsidiary Guarantor
addressed to it at the address of its principal office specified in the first paragraph,
Attention: General Counsel, or at any other address previously furnished in writing to the
Trustee by the Issuer or such Subsidiary Guarantor.

          SECTION 106. Notice to Holders; Waiver.

          Where this Indenture provides for notice of any event to Holders by the Issuer or the Trustee,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as
it appears in 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 Holders is given by
mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to other Holders.
Notices given by publication shall be deemed given on the first date on which publication is made
and notices given by first-class mail, postage prepaid, shall be deemed given five calendar days
after mailing.

          In case by reason of the suspension of or irregularities in regular mail service or by reason
of any other cause, it shall be impracticable to mail notice of any event to Holders when such
notice is required to be given pursuant to any provision of this Indenture, then any manner of
giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient
giving of such notice for every purpose hereunder.

          Where this Indenture provides for notice in any manner, such notice may be waived in writing
by the 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 Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          SECTION 107. Effect of Headings and Table of Contents.

          The Article and Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

-35-

 

          SECTION 108. Successors and Assigns.

          All agreements of the Issuer in this Indenture and the Notes will bind its successors. All
agreements of the Trustee in this Indenture will bind its successors. All agreements of each
Subsidiary Guarantor in this Indenture will bind its successors, except as otherwise provided in
Section 1209 hereof. The provisions of Article Fourteen relating to the Collateral Agent shall
inure to the benefit of such Collateral Agent.

          SECTION 109. Separability Clause.

          In case any provision in this Indenture or in the Notes 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 110. Benefits of Indenture.

          Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other
than the parties hereto, any Paying Agent, any Notes Registrar and their successors hereunder, the
Holders and, with respect to any provisions hereof relating to the subordination of the Notes or the rights of
holders of Senior Indebtedness, the holders of Senior Indebtedness, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

          SECTION 111. Governing Law.

          This Indenture, the Notes and any Guarantee shall be governed by and construed in accordance
with the laws of the State of New York. This Indenture is subject to the provisions of the Trust
Indenture Act that are referred to herein or are otherwise required to be part of this Indenture
and shall, to the extent applicable, be governed by such provisions.

          SECTION 112. Communication by Holders of Notes with Other Holders of Notes.

          Holders may communicate pursuant to Trust Indenture Act Section 312(b) with other Holders with
respect to their rights under this Indenture or the Notes. The Issuer, the Trustee, the Notes
Registrar and anyone else shall have the protection of Trust Indenture Act Section 312(c).

          SECTION 113. Legal Holidays.

          In any case where any Interest Payment Date, Redemption Date or Stated Maturity or Maturity of
any Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture
or of the Notes) payment of principal (or premium, if any) or interest 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 Interest Payment Date, Redemption Date, or at the Stated Maturity or Maturity; provided that
no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date,
Stated Maturity or Maturity, as the case may be.

          SECTION 114. No Personal Liability of Directors, Officers, Employees and Stockholders.

          No director, officer, employee, incorporator or stockholder of the Issuer or any Subsidiary
Guarantor or any of their parent companies shall have any liability for any obligations of the
Issuer or the Subsidiary Guarantors under the Notes, the Guarantees or this Indenture or for any
claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by
accepting a Note and the related Guarantee waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes and the Guarantees. Such waiver
may not be effective to waive liabilities under the federal securities laws and it is the view of
the Commission that such a waiver is against public policy.

-36-

 

          SECTION 115. Trust Indenture Act Controls.

          If any provision of this Indenture limits, qualifies or conflicts with another provision which
is required to be included in this Indenture by the TIA, the provision required by the TIA shall
control. If any provision of this Indenture modifies or excludes any provision of the TIA that may
be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or excluded, as the case may be.

          SECTION 116. Counterparts.

          This Indenture may be executed in any number of counterparts, each of which shall be original;
but such counterparts shall together constitute but one and the same instrument.

          The parties hereto acknowledge that in accordance with Section 326 of the USA Patriot Act the
Trustee and Agents, like all financial institutions and in order to help fight the funding of
terrorism and money laundering, are required to obtain, verify, and record information that
identifies each person or legal entity that establishes a relationship or opens an account. The parties to this Indenture agree that they will
provide the Trustee and the Agents with such information as they may request in order to satisfy
the requirements of the USA Patriot Act.

          SECTION 118. Waiver of Jury Trial.

          THE ISSUER AND THE TRUSTEE HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR

Guarantors and the Trustee, by their execution and delivery of the supplemental indenture described

to be bound thereby. Any reference to a Subsidiary Guarantor herein shall be deemed to be a
reference thereto solely from and after the date of its execution and delivery of a supplemental
indenture hereto in the form of Exhibit D or Exhibit E hereto. However, to the extent any provision
of any Note conflicts with the express provisions of this Indenture, the provisions of this
Indenture shall govern and be controlling.

aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of outstanding Notes represented thereby may from time to time be
reduced or increased,
as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to
reflect the amount of any increase or decrease in the aggregate principal amount of outstanding
Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required by Section 312
hereof.

          The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions
Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and
“Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the

ARTICLE THREE

THE NOTES

          SECTION 301. Title and Terms.

          The aggregate principal amount of Notes which may be authenticated and issued under this
Indenture is not limited; provided, however, that any Additional Notes issued under this Indenture
are issued in accordance with Sections 303 and 1011 hereof, as part of the same series as the
Notes.

          The Notes shall be known and designated as the “12% Senior Secured Notes due 2015” of the
Issuer. The Stated Maturity of the Notes shall be December 1, 2015, and the Notes shall bear
interest at the rate of 12% per annum from December 9, 2009, or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, payable on June 1, 2010 and
semi-annually thereafter on June 1 and December 1 in each year and at said Stated Maturity, until
the principal thereof is paid or duly provided for and to the Person in whose name the Note (or any
predecessor Note) is registered at the close of business on the May 15 and November 15 (whether or
not a Business Day) immediately preceding such Interest Payment Date (each, a “Regular Record
Date”).

          The principal of (and premium, if any) and interest on the Notes shall be payable at the
office or agency of the Issuer maintained for such purpose or, at the option of the Issuer, payment
of interest may be made by check mailed or wire transfer to the Holders of the Notes at their
respective addresses set forth in the Note Register of Holders; provided that all payments of
principal, premium, if any, and interest, if any, with respect to Notes represented by one or more
Global Notes registered in the name of or held by Depositary or its nominee will be made by wire
transfer of immediately available funds to the accounts specified by the Holder or Holders thereof.
Until otherwise designated by the Issuer, the Issuer’s office or agency shall be the office of the
trustee maintained for such purpose.

          Holders shall have the right to require the Issuer to purchase its Notes, in whole or in part,
in the event of a Change in Control pursuant to Section 1017. The Notes shall be subject to
repurchase pursuant to an offer to purchase as provided in Section 1018.

-40-

 

          The Notes shall be redeemable as provided in Article Eleven.

          The due and punctual payment of principal of, premium, if any, and interest on the Notes
payable by the Issuer are irrevocably and unconditionally guaranteed, to the extent set forth
herein, by each of the Subsidiary Guarantors.

          SECTION 302. Denominations.

          The Notes shall be issuable only in registered form without coupons and only in minimum
denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

          SECTION 303. Execution, Authentication, Delivery and Dating.

          The Notes shall be executed on behalf of the Issuer by any two Officers of the Issuer. The
signature of any Officer on the Notes may be manual or facsimile signatures of the present or any
future such authorized officer and may be imprinted or otherwise reproduced on the Notes.

          Notes bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Issuer shall bind the Issuer, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and delivery of such Notes or
did not hold such offices at the date of such Notes.

          At any time and from time to time after the execution and delivery of this Indenture, the
Issuer may deliver Notes executed by the Issuer to the Trustee for authentication, together with an
Issuer Order for the authentication and delivery of such Notes, and the Trustee in accordance with
such Issuer Order shall authenticate and deliver such Notes.

          On the Issue Date, the Issuer shall deliver the Notes in the aggregate principal amount of
$920,000,000 executed by the Issuer to the Trustee for authentication, together with an Issuer
Order for the authentication and delivery of such Notes, directing the Trustee to authenticate the
Notes and certifying that all conditions precedent to the issuance of Notes contained herein have
been fully complied with, and the Trustee in accordance with such Issuer Order shall authenticate
and deliver such Notes. At any time and from time to time after the Issue Date, the Issuer may
deliver Additional Notes executed by the Issuer to the Trustee for authentication, together with an
Issuer Order for the authentication and delivery of such Additional Notes, directing the Trustee to
authenticate the Additional Notes and certifying that the issuance of such Additional Notes is in
compliance with Article Ten hereof and that all other conditions precedent to the issuance of Notes
contained herein have been fully complied with, and the Trustee in accordance with such Issuer
Order shall authenticate and deliver such Additional Notes. In each case, the Trustee shall
receive an Officers’ Certificate and an Opinion of Counsel of the Issuer that it may reasonably
require in connection with such authentication of Notes. Such order shall specify the amount of
Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

          Each Note shall be dated the date of its authentication.

          No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for
any purpose unless there appears on such Note a certificate of authentication substantially in the
form provided for herein duly executed by the Trustee by manual signature of an authorized officer,
and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such
Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this
Indenture.

          In case an Issuer or any Subsidiary Guarantor, pursuant to Article Eight, shall be
consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise
dispose of its properties and assets substantially as an entirety to any Person, and the successor
Person resulting from such consolidation, or surviving such merger, or into which the Issuer or
such Subsidiary Guarantor shall have been merged, or the Person which

-41-

 

shall have received a
conveyance, transfer, lease or other disposition as aforesaid, shall have executed a supplemental
indenture in the form of Exhibit D hereto with the Trustee pursuant to Article Eight, any
of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer,
lease or other disposition may, from time to time, at the request of the successor Person, be
exchanged for other Notes executed in the name of the successor Person with such changes in
phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes
surrendered for such exchange and of like principal amount; and the Trustee, upon Issuer Request of
the successor Person, shall authenticate and deliver Notes as specified in such request for the
purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new
name of a successor Person pursuant to this Section in exchange or substitution for or upon
registration of transfer of any Notes, such successor Person, at the option of the Holders but
without expense to them, shall provide for the exchange of all Notes at the time Outstanding for
Notes authenticated and delivered in such new name.

          SECTION 304. Temporary Notes.

          Pending the preparation of definitive Notes, the Issuer may execute, and upon Issuer Order the
Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of
the tenor of the definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers executing such Notes may
determine, as conclusively evidenced by their execution of such Notes.

          If temporary Notes are issued, the Issuer will cause definitive Notes to be prepared without
unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be
exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuer designated
for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Notes, the Issuer shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of definitive Notes of
authorized denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

          SECTION 305. Registration, Registration of Transfer and Exchange.

          The Issuer shall cause to be kept at the Corporate Trust Office of the Trustee a register (the
register maintained in such office and in any other office or agency designated pursuant to Section
1002 being herein sometimes referred to as the “Note Register”) in which, subject to such
reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes
and of transfers of Notes. The Note Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. At all reasonable times, the Note
Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as
note registrar (the “Note Registrar”) for the purpose of registering Notes and transfers of Notes
as herein provided.

          Upon surrender for registration of transfer of any Note at the office or agency of the Issuer
designated pursuant to Section 1002, the Issuer shall execute, and upon Issuer Order the Trustee
shall authenticate and deliver, in the name of the designated transferee or transferees, one or
more new Notes of any authorized denomination or denominations of a like aggregate principal
amount.

          At the option of the Holder, Notes may be exchanged for other Notes of any authorized
denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged
at such office or agency. Whenever any Notes are so surrendered for exchange, the Issuer shall
execute, and upon Issuer Order the Trustee shall authenticate and deliver, the Notes which the
Holder making the exchange is entitled to receive.

          All Notes issued upon any registration of transfer or exchange of Notes shall be the valid
obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Notes surrendered upon such registration of transfer or exchange.

-42-

 

          Every Note presented or surrendered for registration of transfer or for exchange shall (if so
required by the Issuer) be duly endorsed, or be accompanied by written instruments of transfer, in
form satisfactory to the Issuer, duly executed by the Holder thereof or his attorney duly
authorized in writing.

          No service charge shall be made for any registration of transfer or exchange or redemption of
Notes, but the Issuer may require payment of a sum sufficient to cover any taxes, fees or other
governmental charge that may be imposed in connection with any registration of transfer or exchange
of Notes, other than exchanges pursuant to Sections 303, 304, 906, 1017, 1018 or 1108 not involving
any transfer.

          SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes.

          If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Issuer and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is
delivered to the Issuer and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Issuer or the Trustee that such
Note has been acquired by a bona fide purchaser, the Issuer shall execute and upon Issuer Order the
Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any
such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a
number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Note has become or is about to become
due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such Note.

          Upon the issuance of any new Note under this Section, the Issuer 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 expenses (including the fees and expenses of the Trustee) connected
therewith.

          Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or
stolen Note shall constitute an original additional contractual obligation of the Issuer and each
Subsidiary Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any
time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Notes duly issued hereunder.

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

          SECTION 307. Payment of Interest; Interest Rights Preserved.

          Interest on any Note which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record Date for such
interest at the office or agency of the Issuer maintained for such purpose pursuant to Section
1002; provided, however, that, subject to Section 301 hereof, each installment of interest may at
the Issuer’s option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 308, to the address of such Person
as it appears in the Note Register or (ii) transfer to an account located in the United States
maintained by the payee.

          Any interest on any Note which is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record
Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful)
interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and
interest thereon herein collectively called “Defaulted Interest”) may be paid by the Issuer, at its
election in each case, as provided in clause (1) or (2) below:

     (1) The Issuer may elect to make payment of any Defaulted Interest to the Persons in
whose names the Notes (or their respective Predecessor Notes) are registered at the close of
business on a Special

-43-

 

Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment,
and at the same time the Issuer shall deposit with the Trustee an amount of money equal to
the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall
fix a Special Record Date for the payment of such Defaulted Interest which shall be not more
than 15 days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed payment.
The Trustee shall promptly notify the Issuer of such Special Record Date, and in the name
and at the expense of the Issuer, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be given in the manner provided
for in Section 106, not less than 10 days prior to such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been
so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or
their respective Predecessor Notes) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2).

     (2) The Issuer may make payment of any Defaulted Interest in any other lawful manner
not inconsistent with the requirements of any securities exchange on which the Notes may be
listed, and upon such notice as may be required by such exchange, if, after notice given by
the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of
payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Note delivered under this Indenture
upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

          SECTION 308. Persons Deemed Owners.

          Prior to the due presentment of a Note for registration of transfer, the Issuer, any
Subsidiary Guarantor, the Trustee and any agent of the Issuer or the Trustee may treat the Person
in whose name such Note is registered as the owner of such Note for the purpose of receiving
payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on
such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of
the Issuer, the Trustee or any agent of the Issuer or the Trustee shall be affected by notice to
the contrary.

          SECTION 309. Cancellation.

          All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled by it. The Issuer may at any time deliver to the Trustee for cancellation any Notes
previously authenticated and delivered hereunder which the Issuer may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Notes previously authenticated hereunder which the Issuer has not issued and sold,
and all Notes so delivered shall be promptly cancelled by the Trustee. If the Issuer shall so
acquire any of the Notes, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the same are
surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in
exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in
accordance with its customary procedures.

-44-

 

          SECTION 310. Computation of Interest.

          Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day
months.

          SECTION 311. [INTENTIONALLY DELETED].

          SECTION 312. Book-Entry and Transfer Provisions.

          (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred
except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary
to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be
exchanged by the Issuer for Definitive Notes if:

     (1) the Depositary (a) notifies the Issuer that it is unwilling or unable to continue
as depositary for the Global Notes or (b) has ceased to be a clearing agency registered
under the Exchange Act and, in either case, the Issuer fails to appoint a successor
depositary;

     (2) the Issuer, at its option, notify the Trustee in writing that it elects to cause
the issuance of the Definitive Notes; or

     (3) there has occurred and is continuing a Default or Event of Default with respect to
the Notes and the beneficial owner thereof has requested such exchange.

          Upon the occurrence of either of the events described in Section 312(a)(1) or (2), Definitive
Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes
also may be exchanged or replaced, in whole or in part, as provided in Sections 304 and 306 hereof.
Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Sections
304 or 306 hereof, shall be authenticated and delivered in the form of, and shall be, a Global
Note. A Global Note may not be exchanged for another Note other than as provided in this Section
312(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided
in Section 312(b) or (c) hereof.

          (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer
and exchange of beneficial interests in the Global Notes will be effected through the Depositary,
in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial
interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to
those set forth herein to the extent required by the Securities Act. Transfers of beneficial
interests in the Global Notes also will require compliance with either subparagraph (1) or (2)
below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

     (1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in
any Restricted Global Note may be transferred to Persons who take delivery thereof in the
form of a beneficial interest in the same Restricted Global Note in accordance with the
transfer restrictions set forth in the Private Placement Legend; provided, however, that
prior to the expiration of the Restricted Period, transfers of beneficial interests in the
Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a
U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted
Global Note may be transferred to Persons who take delivery thereof in the form of a
beneficial interest in an Unrestricted Global Note. No written orders or instructions shall
be required to be delivered to the Note Registrar to effect the transfers described in this
Section 312(b)(1).

     (2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In
connection with all transfers and exchanges of beneficial interests that are not subject to
Section 312(b)(1) above, the transferor of such beneficial interest must deliver to the Note
Registrar either:

-45-

 

     (A) both:

     (x) a written order from a Participant or an Indirect Participant given
to the Depositary in accordance with the Applicable Procedures directing the
Depositary to credit or cause to be credited a beneficial interest in
another Global Note in an amount equal to the beneficial interest to be
transferred or exchanged; and

     (y) instructions given in accordance with the Applicable Procedures
containing information regarding the Participant account to be credited with
such increase; or

     (B) both:

     (x) a written order from a Participant or an Indirect Participant given
to the Depositary in accordance with the Applicable Procedures directing the
Depositary to cause to be issued a Definitive Note in an amount equal to the
beneficial interest to be transferred or exchanged; and

     (y) instructions given by the Depositary to the Note Registrar
containing information regarding the Person in whose name such Definitive
Note shall be registered to effect the transfer or exchange referred to in
(A) above.

Upon satisfaction of all of the requirements for transfer or exchange of beneficial
interests in Global Notes contained in this Indenture and the Notes or otherwise applicable
under the Securities Act, the Trustee shall adjust the principal amount of the relevant
Global Note(s) pursuant to Section 312(g) hereof.

     (3) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial
interest in any Restricted Global Note may be transferred to a Person who takes delivery
thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the
requirements of Section 312(b)(2) above and:

     (A) if the transferee will take delivery in the form of a beneficial interest
in the 144A Global Note, then the transferor must deliver to the Note Registrar a
certificate in the form of Exhibit B hereto, including the certifications in item
(1) thereof; and

     (B) if the transferee will take delivery in the form of a beneficial interest
in) the Regulation S Global Note, then the transferor must deliver to the
Note Registrar a certificate in the form of Exhibit B hereto, including the
certifications in item (2) thereof.

     (4) Transfer and Exchange of Beneficial Interests in a Restricted Global Note for
Beneficial Interests in an Unrestricted Global Note. A beneficial interest in any
Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in
an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the
form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer
complies with the requirements of Section 312(b)(2) above and:

     (A) such transfer is effected pursuant to a shelf registration statement; or

     (B) the Note Registrar receives the following:

     (x) if the holder of such beneficial interest in a Restricted Global
Note proposes to exchange such beneficial interest for a beneficial interest
in an Unrestricted Global Note, a certificate from such holder in the form
of Exhibit C hereto, including the certifications in item (1)(a) thereof; or

-46-

 

     (y) if the holder of such beneficial interest in a Restricted Global
Note proposes to transfer such beneficial interest to a Person who shall
take delivery thereof in the form of a beneficial interest in an
Unrestricted Global Note, a certificate from such holder in the form of
Exhibit B hereto, including the certifications in item (4) thereof;

and, in each such case set forth in this subparagraph (B), if the Note Registrar so requests or if
the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the
Note Registrar to the effect that such exchange or transfer is in compliance with the Securities
Act and that the restrictions on transfer contained herein and in the Private Placement Legend are
no longer required in order to maintain compliance with the Securities Act.

If any such transfer is effected pursuant to subparagraph (A) or (B) above at a time when an
Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an
Issuer Order in accordance with Section 202 hereof, the Trustee shall authenticate one or more
Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount
of beneficial interests transferred pursuant to subparagraph (A) or (B) above.

          (c) Transfer or Exchange of Beneficial Interests for Definitive Notes. Beneficial
interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who
take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

     (1) Beneficial Interests in Restricted Global Notes to Restricted Definitive Notes. If
any holder of a beneficial interest in a Restricted Global Note proposes to exchange such
beneficial interest for a Restricted Definitive Note or to transfer such beneficial interest
to a Person who takes delivery thereof in the form of a Restricted Definitive Note, then,
upon receipt by the Note Registrar of the following documentation:

     (A) if the holder of such beneficial interest in a Restricted Global Note
proposes to exchange such beneficial interest for a Restricted Definitive Note, a
certificate from such holder in the form of Exhibit C hereto, including the
certifications in item (2)(a) thereof;

     (B) if such beneficial interest is being transferred to a QIB in accordance
with Rule 144A, a certificate to the effect set forth in Exhibit B hereto, including
the certifications in item (1) thereof;

     (C) if such beneficial interest is being transferred to a Non-U.S. Person in an
offshore transaction in accordance with Rule 903 or Rule 904, a certificate to the
effect set forth in Exhibit B hereto, including the certifications in item (2)
thereof;

     (D) if such beneficial interest is being transferred pursuant to an exemption
from the registration requirements of the Securities Act in accordance with Rule
144, a certificate to the effect set forth in Exhibit B hereto, including the

hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is

Definitive Notes surrendered upon such registration of transfer or exchange.

          (5) Neither the Note Registrar nor the Issuer will be required:

     (A) to issue, to register the transfer of or to exchange any Notes during a period

Holders; provided that any such notice may state that no representation is made as to the
correctness of such CUSIP numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or other identification
numbers printed on the Notes, and any such redemption or repurchase shall not be affected by any
defect in or omission of such numbers. The Issuer will promptly notify the Trustee in writing of
any change in the CUSIP numbers.

          SECTION 314. Issuance of Additional Notes.

has irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable

payable) or to the Stated Maturity or Redemption Date, as the case may be;

     (2) no Default or Event of Default (other than that resulting from borrowing funds to
be applied to make such deposit and the granting of Liens in connection therewith) with
respect to this Indenture or the Notes shall have occurred and be continuing on the date of
such deposit or shall occur as a result of such deposit and such deposit shall not result in

     (3) the Issuer has paid or caused to be paid all sums payable by it under this

provided, however, that a default under Section 501(3), (4), (8) or (9) will not constitute an
Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding
Notes notify the Company of the default and the Company does not cure such default within the time
specified in Section 501(3), (4), (8) or (9) after receipt of such notice.

          SECTION 502. Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default (other than an Event of Default specified in Section 501(7) above)
occurs and is continuing, then and in every such case the Trustee or the Holders of at least 25% in
principal amount of the Outstanding Notes issued under this Indenture may declare the principal,
premium, if any, interest and any other monetary obligations on all the Outstanding Notes to be due
and payable immediately, by a notice in writing to the Issuer (and to the Trustee if given by
Holders).

          Upon the effectiveness of such declaration, such principal and interest will be due and
payable immediately. Notwithstanding the foregoing, if an Event of Default specified in Section
501(7) above occurs and is continuing, then the principal amount of all Outstanding Notes shall
ipso facto become and be immediately due and payable without any notice, declaration or other act
on the part of the Trustee or any Holder.

          At any time after a declaration of acceleration has been made and before a judgment or decree
for payment of the money due has been obtained by the Trustee as hereinafter provided in this
Article, the Holders of a majority in aggregate principal amount of the Outstanding Notes, by
written notice to the Issuer and the Trustee, may rescind and annul such declaration and its
consequences if:

     (a) the Issuer has paid or deposited with the Trustee a sum sufficient to pay:

     (A) all overdue interest on all Outstanding Notes,

-55-

 

     (B) all unpaid principal of (and premium on) any Outstanding Notes which has
become due otherwise than by such declaration of acceleration, and interest on such
unpaid principal at the rate borne by the Notes,

     (C) to the extent that payment of such interest is lawful, interest on overdue
interest at the rate borne by the Notes, and

     (D) all sums paid or advanced by the Trustee or Collateral Agent hereunder and
the reasonable compensation, expenses, disbursements and advances of the Trustee or
Collateral Agent, its agents and counsel; and

     (b) Events of Default, other than the non-payment of amounts of principal of (or
premium, if any, on) or interest on Notes which have become due solely by such declaration
of acceleration, have been cured or waived as provided in Section 513, no such rescission
shall affect any subsequent default or impair any right consequent thereon.

          Notwithstanding the preceding paragraph, in the event of any Event of Default specified in
Section 501(5) above, such Event of Default and all consequences thereof (excluding any resulting
payment default) shall be annulled, waived and rescinded, automatically and without any action by
the Trustee or the Holders, if within 30 days after such Event of Default arose,

     (x) the Indebtedness or guarantee that is the basis for such Event of Default has been
discharged, or

     (y) the holders thereof have rescinded or waived the acceleration, notice or action (as
the case may be) giving rise to such Event of Default, or

     (z) if the default that is the basis for such Event of Default has been cured.

     SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Issuer covenants that if:

     (a) default is made in the payment of any installment of interest on any Note when such
interest becomes due and payable and such default continues for a period of 30 days, or

     (b) default is made in the payment of the principal of (or premium on) any Note at the
Maturity thereof,

the Issuer will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of
such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any)
and interest, and interest on any overdue principal (and premium, if any) and, to the extent that
payment of such interest shall be legally enforceable, upon any overdue installment of interest, at
the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee and the Collateral Agent, its agents and counsel.

          If the Issuer fails to pay such amounts forthwith upon such demand, the Trustee, in its own
name as trustee of an express trust, may institute a judicial proceeding for the collection of the
sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce
the same against the Issuer, any Subsidiary Guarantor or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by law out of the
property of the Issuer, any Subsidiary Guarantor or any other obligor upon the Notes, wherever
situated.

          If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders under this Indenture and the
Guarantees by such appropriate judicial proceedings as the Trustee shall deem necessary to protect
and enforce any such rights, including seeking recourse against any Subsidiary Guarantor, whether
for the specific enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy, including but without
limitation, seeking recourse against any Subsidiary Guarantor.

          SECTION 504. Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Issuer or any other obligor including any Subsidiary Guarantor, upon the Notes or the property of
the Issuer or of such other obligor or their creditors, and subject to the Intercreditor Agreement,
the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as
therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Issuer for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or otherwise,

     (i) to file and prove a claim for the whole amount of principal (and premium, if any)
and interest owing and unpaid in respect of the Notes and to file such other papers or
documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and

     (ii) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee or Collateral Agent, its agents and counsel, and any
other amounts due the Trustee or Collateral Agent under Section 607 or Section 1411, as applicable.

          Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

          SECTION 505. Trustee May Enforce Claims Without Possession of Notes.

          All rights of action and claims under this Indenture or the Notes may be prosecuted and
enforced by the Trustee without the possession of any of the Notes or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name and as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which
such judgment has been recovered.

          SECTION 506. Application of Money Collected.

          Subject to the terms of the Security Documents, any money or property collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal (or premium, if any)
or interest, upon presentation of the Notes and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

-57-

 

     FIRST: To the payment of all amounts due the Trustee under Section 607 and the
Collateral Agent under Section 1411;

     SECOND: To the payment of the amounts then due and unpaid for principal of
(and premium, if any) and interest on the Notes in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on such Notes for principal (and premium, if any)
and interest, respectively; and

     THIRD: The balance, if any, to the Issuer or any other obligor on the Notes,
as their interests may appear or as a court of competent jurisdiction may direct in writing;
provided that all sums due and owing to the Holders, the Collateral Agent and the Trustee
have been paid in full as required by this Indenture.

     SECTION 507. Limitation on Suits.

          No Holder of any Notes shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for
any other remedy hereunder, unless:

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

     (2) the Holders of not less than 25% in principal amount of the Outstanding Notes shall
have made written request to the Trustee to institute proceedings in respect of such Event
of Default in its own name as Trustee hereunder;

     (3) such Holder or Holders have offered to the Trustee indemnity reasonably
satisfactory to it against the costs, expenses and liabilities to be incurred in compliance
with such request;

     (4) the Trustee for 30 days after its receipt of such notice, request and offer of
indemnity has failed to institute any such proceeding; and

     (5) no direction inconsistent with such written request has been given to the Trustee
during such 30-day period by the Holders of a majority or more in principal amount of the
Outstanding Notes;

it being understood and intended that no one or more Holders shall have any right in any manner
whatever by virtue of, or by availing of, any provision of this Indenture or the Guarantees to
affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain
priority or preference over any other Holders or to enforce any right under this Indenture or the
Guarantees, except in the manner herein provided and for the equal and ratable benefit of all the
Holders (it being further understood that the Trustee does not have an affirmative duty to
ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

          SECTION 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

          Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the
right, which is absolute and unconditional, to receive payment, as provided herein (including, if
applicable, Article Eleven) and in such Note of the principal of (and premium, if any) and (subject
to Section 307) interest on such Note on the respective Stated Maturities expressed in such Note
(or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent of such Holder.

-58-

 

          SECTION 509. Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture or the Guarantees and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder, then and in every
such case, subject to any determination in such proceeding, the Issuer, any Subsidiary Guarantor,
any other obligor of the Notes, the Trustee and the Holders shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been instituted.

          SECTION 510. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Notes in the last paragraph of Section 306, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders 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 or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          SECTION 511. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any Note to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

          SECTION 512. Control by Holders.

          Subject to the terms of the Security Documents, the Holders of not less than a majority in
principal amount of the Outstanding Notes shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or Collateral Agent, or
exercising any trust or power conferred on the Trustee or Collateral Agent, provided that:

     (1) such direction shall not be in conflict with any rule of law or with this
Indenture,

     (2) subject to Section 315 of the Trust Indenture Act, the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such direction, and

     (3) the Trustee need not take any action which might involve it in personal liability
or be unjustly prejudicial to the Holders not consenting.

     (4) prior to taking any such action, the Trustee or Collateral Agent shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses and expenses
caused by taking or not taking such action.

          SECTION 513. Waiver of Past Defaults.

          Subject to Sections 508 and 902 and the last paragraph of Section 502, the Holders of not less
than a majority in principal amount of the Outstanding Notes may on behalf of the Holders of all
such Notes waive any past Default hereunder and its consequences, except a continuing Default or
Event of Default (1) in respect of the payment of interest on, premium, if any, or the principal of
any such Note held by a non-consenting Holder, or (2) in

-59-

 

respect of a covenant or provision hereof
which under Article Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Note affected.

          Upon any such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such
waiver shall extend to any subsequent or other Default or Event of Default or impair any right
consequent thereon.

          SECTION 514. Waiver of Stay or Extension Laws.

          The Issuer, the Subsidiary Guarantors and any other obligor on the Notes covenants (to the
extent that it may lawfully do so) that it will 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, which may affect the covenants or the performance
of this Indenture; and the Issuer, the Subsidiary Guarantors and any other obligor on the Notes (to
the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no
such law had been enacted.

ARTICLE SIX

THE TRUSTEE

     SECTION 601. Duties of the Trustee.

     (a) Except during the continuance of a Default or an Event of Default,

     (1) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

     (2) in the absence of bad faith or willful misconduct on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the opinions
expressed therein, upon certificates or opinions furnished to the Trustee and conforming to
the requirements of this Indenture; but in the case of any such certificates or opinions
specifically required by any provision hereof to be provided to it, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture, but not to verify the contents thereof.

          (b) In case an Event of Default has occurred and is continuing of which a Responsible Officer
of the Trustee has actual knowledge or of which written notice of such Default or Event of Default
shall have been given to the Trustee by the Issuer, any other obligor of the Notes or by any
Holder, the Trustee shall exercise such of the rights and powers vested in it by this Indenture,
and use the same degree of care and skill in their exercise, as a prudent Person would exercise or
use under the circumstances in the conduct of such Person’s own affairs.

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

     (1) this paragraph (c) shall not be construed to limit the effect of paragraph (a) of
this Section;

     (2) the Trustee shall not be liable for any error of judgment made in good faith by a
Responsible Officer, unless it shall be proved that the Trustee was negligent in
ascertaining the pertinent facts;

-60-

 

     (3) the Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the Holders of a majority in
aggregate principal amount of the Outstanding Notes relating to the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or exercising any
trust or power conferred upon the Trustee, under this Indenture; and

     (4) no provision of this Indenture shall require the Trustee to expend or risk its own
funds 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.

          (d) Whether or not therein expressly so provided, every provision of this Indenture relating
to the conduct or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

          SECTION 602. Notice of Defaults.

          Within 90 (ninety) days after the earlier of receipt from the Issuer of notice of the
occurrence of any Default or Event of Default hereunder or the date when such Default or Event of
Default becomes known to the
Trustee, the Trustee shall transmit, in the manner and to the extent provided in TIA Section
313(c), notice of such Default or Event of Default hereunder known to the Trustee, unless such
Default or Event of Default shall have been cured or waived; provided, however, that, except in the
case of a Default or Event of Default in the payment of the principal of (or premium, if any, on)
or interest on any Note, the Trustee shall be protected in withholding such notice if and so long
as a trust committee of Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interest of the Holders.

indebtedness or other paper or document (whether in original or facsimile form) believed by

     (2) any request or direction of the Issuer mentioned herein shall be sufficiently
evidenced by an Issuer Request or Issuer Order and any resolution of the Board of Directors

action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may,
in the absence of bad faith on its part, rely upon an Officers’ Certificate;

     (4) the Trustee may consult with counsel of its own selection and the advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith and in
reliance thereon;

     (5) the Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders pursuant to

indemnity satisfactory to it against the

-61-

 

costs, expenses, losses and liabilities which might
be incurred by it in compliance with such request or direction;

     (6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Issuer, personally or by agent or attorney at the expense
of the Issuer and shall incur no liability of any kind by reason of such inquiry or
investigation;

     (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder;

     (8) the Trustee shall not be liable for any action 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;

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

     (10) the Trustee may request that the Issuer deliver an Officers’ Certificate
substantially in the Form of Exhibit F hereto setting forth the names of individuals and/or
titles of officers authorized at such time to take specified actions pursuant to this
Indenture, which Officers’ Certificate may be signed by any person authorized to sign an
Officers’ Certificate, including any person specified as so authorized in any such
certificate previously delivered and not superseded;

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

     (12) the Trustee shall not be liable for the actions or omissions of the Escrow Issuer,
Company, Finance Co, the Subsidiary Guarantors, or any other Person and without limiting the
foregoing, the Trustee shall not be under any obligation to monitor, evaluate or verify
compliance by the Escrow Issuer, Company, Finance Co or the Subsidiary Guarantors with the
terms hereof or the Note Documents, or to verify or independently determine the accuracy of
information received by the Trustee from the Escrow Issuer, the Company, Finance Co or the
Subsidiary Guarantors (or from any selling institution, agent bank, trustee or similar
source) with respect to the Collateral or the Escrow Collateral, as the case may be;

     (13) any permissive right of the Trustee to take or refrain from taking actions
enumerated in this Indenture or the Note Documents shall not be construed as a duty;

     (14) the Trustee shall not be deemed to have notice or knowledge of any matter unless a
Trust Officer has actual knowledge thereof or unless written notice thereof is received by
the Trustee and Collateral Agent at the Corporate Trust Office and such notice references
the Notes generally, the Company or this Indenture. Whenever reference is made in this
Indenture to a Default or an Event of Default such reference shall, insofar as determining
any liability on the part of the Trustee is concerned, be construed to refer only to a
Default or an Event of Default of which the Trustee is deemed to have knowledge in
accordance with this paragraph; and

-62-

 

     (15) to the extent not inconsistent herewith, the rights, protections, immunities and
indemnities afforded to the Trustee pursuant to this Indenture also shall be afforded to the
Collateral Agent.

          The Trustee shall not be required to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the exercise of any of

or adequate indemnity against such risk or liability is not reasonably assured to it.

          SECTION 604. Trustee Not Responsible for Recitals or Issuance of Notes.

          The recitals contained herein and in the Notes, except for the Trustee’s certificates of
authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture, the Note Documents or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture the Note Documents,
authenticate the Notes and perform its obligations hereunder and that the statements made by it in
a “Statement of Eligibility” on Form T-1 supplied to the Issuer are true and accurate, subject to
the qualifications set forth therein. The Trustee shall not be accountable for the use or
application by the Issuer of Notes or the proceeds thereof.

          SECTION 605. May Hold Notes.

          The Trustee, any Paying Agent, any Note Registrar or any other agent of the Issuer or of the
Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and,
subject to TIA Sections 310(b) and 311, may otherwise deal with the Issuer with the same rights it
would have if it were not the Trustee, Paying Agent, Note Registrar or such other agent; provided,
however, that, if it acquires any conflicting interest, it must eliminate such conflict within 90
days, apply to the Commission for permission to continue or resign.

          SECTION 606. Money Held in Trust.

          Money held by the Trustee in trust hereunder need not be segregated from other funds except to

          SECTION 607. Compensation and Reimbursement.

          The Issuer agrees:

     (1) to pay to the Trustee from time to time such compensation as shall be agreed in
writing between the Issuer and the Trustee for all services rendered by it hereunder (which
compensation shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

     (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any provision of this Indenture or other Note Document (including
the reasonable compensation and the expenses and disbursements of its agents (which may
include the Existing Secured Notes Collateral Agent) and counsel), except any such expense,
disbursement or advance as shall be determined to have been caused by its own negligence (or
gross negligence in the case of the Collateral Agent) or willful misconduct; and

     (3) to indemnify the Trustee and any predecessor Trustee (and each of their officers,
directors, employees, counsel and agents (which may include the Existing Secured Notes
Collateral Agent)) for, and to hold it harmless against, any and all loss, liability, claim,
damage or expense, including taxes

-63-

 

(other than the taxes based on the income of the Trustee)
incurred without negligence (or gross negligence in the case of the Collateral Agent) or
willful misconduct on its part, arising out of or in connection with the acceptance or
administration of this trust and the performance of its duties under this Indenture and the
Note Documents including the costs and expenses of defending itself against any claim
regardless of whether the claim is asserted by the Issuer, a Subsidiary Guarantor, a Holder
or any other Person or liability in connection with the exercise or performance of any of
its powers or duties hereunder.

          The obligations of the Issuer under this Section to compensate the Trustee, to pay or
reimburse the Trustee for expenses, disbursements and advances and to indemnify and hold harmless
the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture and resignation or removal of the Trustee. As security for the
performance of such obligations of the Issuer, the Trustee shall have a Lien prior to the Notes
upon all property and funds held or collected by the Trustee as such, except funds held in trust
for the payment of principal of (and premium, if any) or interest on particular Notes.

          When the Trustee incurs expenses or renders services in connection with an Event of Default
specified in Section 501(6), the expenses (including the reasonable charges and expenses of its
counsel) of and the compensation for such services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or other similar law.

          The provisions of this Section shall survive the termination of this Indenture.

          SECTION 608. Corporate Trustee Required; Eligibility.

          There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee
under TIA Sections 310(a)(1), (2) and (5) and shall have a combined capital and surplus of at least
$50,000,000. If such corporation publishes reports of condition at least annually, pursuant to law
or to the requirements of Federal, State, territorial or District of Columbia supervising or
examining authority, then for the purposes of this Section, the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

          SECTION 609. Resignation and Removal; Appointment of Successor.

          (a) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 610.

          (b) The Trustee may resign at any time by giving written notice thereof to the Issuer. Upon
receiving such notice of resignation, the Issuer shall promptly appoint a successor trustee by
written instrument executed by authority of the Board of Directors, a copy of which shall be
delivered to the resigning Trustee and a copy to the successor trustee. If the instrument of
acceptance by a successor Trustee required by Section 610 shall not have been delivered to the
Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may
petition, at the expense of the Issuer, any court of competent jurisdiction for the appointment of
a successor Trustee.

          (c) The Trustee may be removed at any time by Act of the Holders of not less than a majority
in principal amount of the Outstanding Notes, delivered to the Trustee and to the Issuer. If the
instrument of acceptance by a successor Trustee required by Section 610 shall not have been

resigning Trustee may petition, at the expense of the Issuer, any court of competent jurisdiction
for the appointment of a successor Trustee.

-64-

 

          (d) If at any time:

     (1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after
written request therefor by the Issuer or by any Holder who has been a bona fide Holder of a
Note for at least six months, or

     (2) the Trustee shall cease to be eligible under Section 608 and shall fail to resign
after written request therefor by the Issuer or by any Holder who has been a bona fide
Holder of a Note for at least six months, or

     (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then, in any such case, (i) the
Issuer, by a Board Resolution, may remove the Trustee, or (ii) subject to TIA Section
315(e), any Holder who has been a bona fide Holder of a Note for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

          (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, the Issuer, by a Board Resolution, shall
promptly appoint a successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount of the Outstanding
Notes delivered to the Issuer and the retiring Trustee, the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment, become the successor Trustee and
supersede the successor Trustee appointed by the Issuer. If no successor Trustee shall have been
so appointed by the Issuer or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Note for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent jurisdiction
for the appointment of a successor Trustee.

          (f) The Issuer shall give notice of each resignation and each removal of the Trustee and each
appointment of a successor Trustee to the Holders in the manner provided for in Section 106. Each
notice shall include the name of the successor Trustee and the address of its Corporate Trust
Office.

          SECTION 610. Acceptance of Appointment by Successor.

          (a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the
Issuer and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee; but, on request of the Issuer or the successor Trustee,
such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all property and money held
by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Issuer shall
execute any and all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

          (b) Upon request of any such successor Trustee, the Issuer shall execute any and all

          SECTION 611. Merger, Conversion, Consolidation or Succession to Business.

          Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if such successor
Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have
been authenticated, any successor Trustee may authenticate such Notes either in the name of any
predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates
shall have the full force and effect which this Indenture provides for the certificate of
authentication of the Trustee shall have; provided, however, that the right to adopt the
certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of
any predecessor Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

          SECTION 612. Appointment of Authenticating Agent.

          At any time when any of the Notes remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents with respect to the Notes which shall be authorized to act on behalf
of the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment
to all Holders of Notes with respect to which such Authenticating Agent will serve, in the manner
provided for in Section 106. Notes so authenticated shall
be entitled to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by
an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such
instrument shall be promptly furnished to the Issuer. Wherever reference is made in this Indenture
to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of
authentication, such reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Issuer and shall at all times be a corporation organized and doing business under the laws of the
United States of America, any state thereof or the District of Columbia, authorized under such laws
to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000
and subject to supervision or examination by Federal or state authority. If such corporation
publishes reports of condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time an Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect specified in this Section.

          Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further act on the part of
the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Issuer. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Issuer. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Issuer and shall give
written notice of such appointment to all Holders of Notes, in the manner provided for in Section
106. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become

-66-

 

vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

          The Issuer agrees to pay to each Authenticating Agent from time to time such compensation for
its services under this Section as shall be agreed in writing between the Issuer and such
Authenticating Agent.

          If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in
addition to the Trustee’s certificate of authentication, an alternate certificate of authentication
in the following form:

          This is one of the Notes designated therein referred to in the within-mentioned Indenture.

ARTICLE TEN

COVENANTS

          SECTION 1001. Payment of Principal, Premium, if Any, and Interest.

          The Issuer covenants and agrees for the benefit of the Holders that it will duly and
punctually pay the principal of (and premium, if any) and interest on the Notes in accordance with
the terms of the Notes and this Indenture.

          SECTION 1002. Maintenance of Office or Agency.

          The Issuer will maintain an office or agency 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 and this Indenture may be served. The
designated office of the Trustee shall be such office or agency of the Issuer, unless the Issuer
shall designate and maintain some other office or agency for one or more of such purposes. The
Issuer will give prompt written notice to the Trustee of any change in the location of any such
office or agency. If at any time the Issuer shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee,
and the Issuer hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

          The Issuer may also from time to time designate one or more other offices or agencies where
the Notes may be presented or surrendered for any or all such purposes and may from time to time
rescind any such designation; provided, however, that no such designation or rescission shall in
any manner relieve the Issuer of its obligation to maintain an office or agency for such purposes.
The Issuer will give prompt written notice to the Trustee of any such designation or rescission and
any change in the location of any such other office or agency.

          SECTION 1003. Money for Notes Payments to Be Held in Trust.

          If the Issuer shall at any time act as its own Paying Agent, it will, on or before each due
date of the principal of (or premium, if any) or interest on any of the Notes, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of
(or premium, if any) or interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

          Whenever the Issuer shall have one or more Paying Agents for the Notes, it will, on or before
each due date of the principal of (or premium, if any) or interest on any Notes, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Issuer will promptly notify
the Trustee of such action or any failure so to act.

          The Issuer will cause each Paying Agent (other than the Trustee) to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will:

-75-

 

     (1) hold all sums held by it for the payment of the principal of (and premium, if any)
or interest on Notes in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as herein provided;

     (2) give the Trustee notice of any default by the Issuer (or any other obligor upon the
Notes) in the making of any payment of principal (and premium, if any) or interest; and

     (3) at any time during the continuance of any such default, upon the written request of
the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

          The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Issuer Order direct any Paying Agent to pay, to
the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the Issuer or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be
released from all further liability with respect to such sums.

          Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust
for the payment of the principal of (or premium, if any) or interest on any Note and remaining
unclaimed for two years after such principal, premium or interest has become due and payable shall
be paid to the Issuer on Issuer Request, or (if then held by the Issuer) shall be discharged from
such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look
only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Issuer as Trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being required to make any
such repayment, shall at the expense 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 will be repaid to the
Issuer.

          SECTION 1004. Corporate Existence.

          Subject to Article Eight, the Issuer will do or cause to be done all things necessary to
preserve and keep in full force and effect the corporate existence and that of each Restricted
Subsidiary and the corporate rights (charter and statutory) and franchises of the Issuer and each
Restricted Subsidiary; provided, however, that the Issuer shall not be required to preserve any
such right or franchise if management of the Issuer shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries as a
whole.

          SECTION 1005. Payment of Taxes and Other Claims.

          The Issuer will pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the
Issuer or any Subsidiary or upon the income, profits or property of the Issuer or any Subsidiary
and (b) all lawful claims for labor, materials and supplies, which, if unpaid, might by law become
a lien upon the property of the Issuer or any Subsidiary; provided, however, that the Issuer shall
not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in good faith by
appropriate proceedings and for which appropriate reserves, if necessary (in the good faith
judgment of management of the Issuer) are being maintained in accordance with GAAP.

          SECTION 1006. Maintenance of Properties.

          The Issuer will cause all properties owned by the Issuer or any Restricted Subsidiary or used
or held for use in the conduct of its business or the business of any Restricted Subsidiary to be

-76-

 

good condition, repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Issuer may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times; provided, however,
that nothing in this Section shall prevent the Issuer from discontinuing the maintenance of any of
such properties if such discontinuance is, in the judgment of management of the Issuer, desirable
in the conduct of its business or the business of any Restricted Subsidiary.

          SECTION 1007. Insurance.

          From and after the Escrow Release Date:

          (a) the Issuer will at all times keep all of its and the Company’s Subsidiaries properties

against loss or damage to the extent that property of similar character is usually so insured by
corporations similarly situated and owning like properties;

          (b) the Issuer and Subsidiary Guarantors (i) will cause any insurance policies covering any
Collateral to be endorsed or otherwise amended to include a customary lender’s loss payable
endorsement, in form and substance reasonably satisfactory to the Trustee, which endorsement shall
provide that, from and after the Escrow Release Date, if the insurance carrier shall have received
written notice from the Trustee of the occurrence of an Event of Default, the insurance carrier
shall pay all proceeds otherwise payable to the Issuer and the Subsidiary Guarantors under such
policies directly to the Trustee; (ii) will cause all such policies to provide that neither the
Issuer, the Trustee nor any other party shall be a coinsurer thereunder and to contain a
“Replacement Cost Endorsement,” without any deduction for depreciation, and such other provisions
as the Trustee may reasonably require from time to time to protect their interests; (iii) deliver
original or certified copies of all such policies to the Trustee; cause each such policy to provide
that it shall not be canceled, modified or not renewed (x) by reason of nonpayment of premium upon
not less than 10 days’ prior written notice thereof by the insurer to the Trustee (giving the
Trustee the right to cure defaults in the payment of premiums (at the expense of the Issuer)) or
(y) for any other reason upon not less than 30 days’ prior written notice thereof by the insurer to
the Trustee; and (iv) will deliver to the Trustee, prior to the cancellation, modification or
nonrenewal of any such policy of insurance, a draft copy of a renewal or replacement policy (or
other evidence of renewal of a policy previously delivered to the Trustee) and reasonably promptly
thereafter deliver a duplicate original copy of such policy together with evidence satisfactory to
the Trustee of payment of the premium therefor; and

          (c) the Issuer and the Subsidiary Guarantors will notify the Trustee promptly whenever any
separate insurance concurrent in form or contributing in the event of loss with that required to be
maintained under this covenant is taken out by the Issuer or any Subsidiary Guarantor, and promptly
deliver to the Trustee a duplicate original copy of such policy or policies.

          SECTION 1008. Statement by Officers as to Default.

          (a) The Issuer will deliver to the Trustee within 120 days after the end of each fiscal year,
an Officers’ Certificate stating that a review of the activities of the Issuer and the Restricted
Subsidiaries during the preceding fiscal year, has been made under the supervision of the signing
officers with a view to determining whether it has kept, observed, performed and fulfilled, and has
caused each of its Restricted Subsidiaries to keep, observe, perform and fulfill its obligations
under this Indenture and further stating, as to each such officer signing such certificate, that,
to the best of his or her knowledge, the Issuer during such preceding fiscal year, has kept,
observed, performed and fulfilled, and has caused each of its Restricted Subsidiaries to keep,
observe, perform and fulfill each and every such covenant contained in this Indenture and no
Default or Event of Default occurred during such fiscal year, and at the date of such certificate
there is no Default or Event of Default which has occurred and is continuing or, if such signers do
know of such Default or Event of Default, the certificate shall describe its status, with
particularity and that, to the best of his or her knowledge, no event has occurred and remains by
reason of which payments on the account of the principal of or interest, if any, on the Notes is
prohibited or if such event has

-77-

 

occurred, a description of the event and what action each is taking or proposes to take with
respect thereto. The Officers’ Certificate shall also notify the Trustee should the Issuer elect
to change the manner in which it fixes its fiscal year-end. For purposes of this Section 1008(a),
such compliance shall be determined without regard to any period of grace or requirement of notice
under this Indenture.

          (b) When any Default or Event of Default has occurred and is continuing under this Indenture,
the Issuer shall deliver to the Trustee by registered or certified mail or facsimile transmission

information relating to the Issuer by furnishing information relating to the Parent;
provided that, with respect to any audited or unaudited financial statements, the same is
accompanied by consolidating information that explains in reasonable detail the differences
between the financial information relating to the Parent, on the one hand, and the
information relating to the Issuer and the Restricted Subsidiaries on a stand-alone basis,
on the other hand.

     (c) If Parent or the Company has electronically filed with the Securities and Exchange
Commission’s Next-Generation EDGAR system (or any successor system), the reports described
in clause (a) above (including any consolidating information required by clause (b), unless
otherwise provided to the Trustee and the Holders), the Issuer shall be deemed to have
satisfied the foregoing requirements.

     (d) The Issuer shall also hold quarterly conference calls for the Holders of the Notes
to discuss financial information for the previous quarter. The conference call shall be
following the last day of each fiscal quarter of the Issuer and not later than ten business
days from the time that the Issuer distributes the financial information as described
Section 1009(a)(1) and (2), as applicable above. No fewer than two days prior to the
conference call, the Issuer shall issue a press release announcing the time and date of such
conference call and providing instructions for Holders, securities analysts and prospective
investors to obtain access to such call. For the avoidance of doubt, the Issuer may satisfy
the requirements of this paragraph by (i) combining the conference calls required above with

cash and/or Cash Equivalents) and (B) any proceeds received from an Unrestricted
Subsidiary on account of such Equity Interests or Indebtedness, provided, that, in
the case of clause (B), such proceeds will be excluded from EBITDA for purposes of
Section 1010(a)(C)(1) and (C)(5);

     (16) Investments in joint ventures; provided that the aggregate Restricted
Payments made pursuant to this clause (16) do not exceed 5.0% of the fair market
value of Spectrum Assets located in the United States; provided further that to the
extent any such Investment is made in the form of Spectrum Assets such Spectrum
Assets represent Non-Core Spectrum Assets; and provided, further, that such amount
shall be increased by an amount not to exceed (A) the cash proceeds received as a
dividend, distribution or otherwise from such joint ventures (it being understood
that the forgiveness of any debt by such joint venture will not be a Restricted
Payment hereunder) less (B) the amount of any Restricted Payments previously made
pursuant to this Section 1010(b)(16)(A);

     (17) distributions or payments of Receivables Fees; and

     (18) Investments in Unrestricted Subsidiaries having an aggregate fair market
value, when taken together with all other Investments made pursuant to this Section
1010(b)(18) that are at the time outstanding, without giving effect to the sale of
an Unrestricted Subsidiary to the extent the proceeds of such sale do not consist of
cash or Cash Equivalents, not to exceed $50.0 million at the time of such Investment
(with the fair market value of each Investment being measured at the time made and
without giving effect to subsequent changes in value);

provided however, that at the time of, and after giving effect to, any Restricted Payment
permitted under Sections 1010(b)(5), (6) and (10), no Default or Event of Default shall have
occurred and be continuing or would occur as a consequence thereof.

          For all purposes of this Indenture, Restricted Payments (and to the extent an
Investment, outstanding on the Escrow Release Date) made between the Existing Secured Notes
Issue Date and the

-85-

 

Escrow Release Date pursuant to any provision of Section 1010(b) of the
Existing Secured Notes Indenture shall be deemed to have been made pursuant to the
corresponding provision of Section 1010(b) of this Indenture.

     (c) The amount of all Restricted Payments (other than cash) will be the fair market
value (as determined by the Issuer) on the date of such Restricted Payment of the assets or
securities proposed to be paid, transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to such Restricted Payment.

     (d) The Issuer will not permit any Unrestricted Subsidiary to become a Restricted
Subsidiary except pursuant to the last sentence of the definition of “Unrestricted
Subsidiary” in Section 101 of this Indenture. For purposes of designating any Restricted
Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Issuer and its
Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will
be deemed to be Restricted Payments in an amount determined as set forth in the last
sentence of the definition of “Investment.” Such designation will be permitted only if a
Restricted Payment in such amount would be permitted at such time, whether pursuant to
Section 1010(a) or Section 1010(b)(9) or (10), or pursuant to the definition of “Permitted
Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. Unrestricted Subsidiaries shall not be subject to any of the restrictive
covenants set forth in this Indenture. Notwithstanding the foregoing, no Spectrum Entity
shall at any time pay a dividend or make any distribution to any entity that is not a
Spectrum Entity unless the proceeds of any such dividend or distribution is applied in its
entirety to repurchase Notes; provided that, any Spectrum Entity may pay a dividend or make
distributions to the Company so that the Company may make tax distributions pursuant to its
limited liability company agreement, so long as the Company uses the dividend or
distribution to pay such tax distributions at such time.

          SECTION 1011. Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock
and Preferred Stock.

          From and after the Escrow Release Date:

     (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly
or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or
indirectly liable, contingently or otherwise, (collectively, “incur” and collectively, an
“incurrence”) with respect to any Indebtedness (including Acquired Indebtedness) and the
Issuer shall not issue any shares of Disqualified Stock and shall not permit any Restricted
Subsidiary to issue any shares of Disqualified Stock or preferred stock; provided, however,
that the Issuer may incur Indebtedness (including Acquired Indebtedness) or issue shares of
Disqualified Stock, and any Subsidiary Guarantor (other than any Spectrum Entity) may incur
Indebtedness (including Acquired Indebtedness), issue shares of Disqualified Stock and issue
            shares of preferred stock, if the Consolidated Leverage Ratio of the Issuer and the
Restricted Subsidiaries at the time such additional Indebtedness is incurred or such
Disqualified Stock or preferred stock is issued would have been no greater than 6.50 to
1.00, determined on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Stock
or preferred stock had been issued, as the case may be, and the application of proceeds
therefrom had occurred at the beginning of the most recently ended four full fiscal quarters
for which internal financial statements are available.

     (b) The foregoing limitations shall not apply to:

(other than any Spectrum Entity), to finance the purchase, lease or improvement of property (real
or personal) or equipment (other than any Spectrum Assets) that is used or useful in
a Similar Business, whether through the direct purchase of assets or the Capital
Stock of any Person owning such assets, in an aggregate principal amount which, when
aggregated with the principal amount of all other Indebtedness, Disqualified Stock
and preferred stock then outstanding and incurred pursuant to this Section
1011(b)(3) and including all Refinancing Indebtedness incurred to refund, refinance
or replace any other Indebtedness, Disqualified Stock and preferred stock incurred
pursuant to this Section 1011(b)(3), does not exceed $300.0 million;

constituting reimbursement obligations with respect to letters of credit issued in
the ordinary course of business, including without limitation letters of credit in

however, that upon the drawing of such letters of credit or the incurrence of such
Indebtedness, such obligations are reimbursed within 30 days following such drawing
or incurrence;

     (5) Indebtedness arising from agreements of the Issuer or a Restricted
Subsidiary providing for and to the extent of (x) indemnification, adjustment of
purchase price or similar obligations, in each case, incurred or assumed in
connection with the disposition of any business, assets or a Subsidiary other than
guarantees of Indebtedness incurred by any Person acquiring all or any portion of
such business, assets or a Subsidiary for the purpose of financing such acquisition;
provided that the maximum assumable liability in respect of all such Indebtedness
shall at no time exceed the gross proceeds including noncash proceeds (the fair
market value of such noncash proceeds being measured at the time received and
without giving effect to any subsequent changes in value) actually received by the
Issuer and the Restricted Subsidiaries in connection with such disposition and (y)
working capital or other similar balance sheet related purchase price adjustments
incurred or assumed in connection with the acquisition of a Subsidiary;

     (6) Indebtedness of the Issuer to a Subsidiary Guarantor; provided that any
subsequent issuance or transfer of any Capital Stock or any other event which
results in any such Subsidiary Guarantor ceasing to be a Subsidiary Guarantor or any
other subsequent transfer of any such Indebtedness (except to the Issuer or another
Subsidiary Guarantor) shall be deemed, in each case to be an incurrence of such
Indebtedness not permitted by this Section 1011(b)(6);

     (7) Indebtedness of the Issuer or a Subsidiary Guarantor to a Restricted
Subsidiary that is not a Subsidiary Guarantor; provided that any such Indebtedness
is subordinated in right of payment to the Notes; provided further that any
subsequent issuance or transfer of any Capital Stock or any other event which
results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or
any other subsequent transfer of any such Indebtedness (except to the Issuer or
another Restricted Subsidiary) shall be deemed, in each case, to be an incurrence of
such Indebtedness not permitted by this Section 1011(b)(7);

subsequent

-87-

     (9) Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor
to the Issuer or a Restricted Subsidiary;

of any Capital Stock or any other event which results in any such Restricted
Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of
any such shares of preferred stock (except to the Issuer or another Restricted
Subsidiary) shall be deemed in each case to be an issuance of such shares of
preferred stock not permitted by this Section 1011(b)(10);

     (11) Hedging Obligations (excluding Hedging Obligations entered into for
speculative purposes) for the purpose of limiting:

     (A) interest rate risk with respect to any Indebtedness permitted to be

and contributed in cash to the Company after the Existing Secured Notes
Issue Date (but including any net cash proceeds from the New Equity

Notes Issue Date) plus (ii) 75% of the net cash proceeds from the New Equity
Investment in excess of such first $1.0 billion (whether received before or
after the Existing Secured Notes Issue Date) plus (iii) 50% of the net cash

(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness, Disqualified Stock or preferred stock had been
incurred and the application of proceeds therefrom had occurred at the
beginning of the most recently ended four fiscal quarters for which internal

     (ii) any guarantee by a Restricted Subsidiary of Indebtedness of the Issuer or
a Subsidiary Guarantor; provided that such guarantee is incurred in accordance with

stock including additional Indebtedness, Disqualified Stock or preferred stock
incurred to pay premiums, defeasance costs and fees in connection therewith (the

such Refinancing Indebtedness must be
Disqualified Stock or preferred stock, respectively; and

(iii) shall not include

     (x) Indebtedness, Disqualified Stock or preferred stock of a

provisions, in each case, that were customary in high yield subordination terms
prevailing in November 2009);

     (23) Indebtedness of the Issuer or any Subsidiary Guarantor (other than any

and liquidation preference of all other Indebtedness, Disqualified Stock and
preferred stock then outstanding and incurred pursuant to this clause (25), does not
at any one time outstanding exceed $50 million.

     (c) For purposes of determining compliance with this Section 1011, in the event that an
item of Indebtedness, Disqualified Stock or preferred stock meets the criteria of more than
one of the categories of permitted Indebtedness, Disqualified Stock or preferred stock
described in clauses (1) through (25) of this Section 1011(b) or is entitled to be incurred
pursuant to Section 1011(a), the Issuer shall, in its sole discretion, classify or
reclassify such item of Indebtedness in any manner that complies with this covenant and such
item of Indebtedness, Disqualified Stock or preferred stock shall be treated as having been
incurred pursuant to only one of such clauses of this Section 1011(b) or pursuant to Section
1011(a) hereof. Additionally, all or any portion of any item of Indebtedness may later be
reclassified as having been incurred pursuant to any category of permitted Indebtedness
described in clauses (1) through (25) above or pursuant to the first paragraph of this
covenant so long as such Indebtedness is permitted to be incurred pursuant to such provision
at the time of reclassification. Any Indebtedness, Disqualified Stock or preferred stock
incurred between the Existing Secured Notes Issue Date and the Escrow Release Date and
outstanding immediately after the Escrow Release Date shall be deemed to have been initially
incurred under the clause of this Section 1011 that corresponds to the clause of Section
1011 of the Existing Secured Notes Indenture that such Indebtedness, Disqualified Stock or
preferred stock is classified by the Issuer as having been incurred under at the time of the
Escrow Release Date for purposes of the Existing Secured

-91-

 

Notes Indenture; provided that the
Notes issued on the Issue Date and the related Guarantees shall be deemed to be incurred
under clause (b)(1) of this Section 1011. Accrual of interest, the accretion of accreted
value and the payment of interest in the form of additional Indebtedness, Disqualified Stock
or preferred stock shall not be deemed to be an incurrence of Indebtedness, Disqualified
Stock or preferred stock for purposes of this Section 1011.

     (d) For purposes of determining compliance with any U.S. dollar-denominated restriction
on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of
Indebtedness denominated in a foreign currency shall be calculated based on the relevant
currency exchange rate in effect on the date such Indebtedness was incurred, in the case of
term debt, or first committed, in the case of revolving credit debt; provided that if such
Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency,
and such refinancing would cause the applicable U.S. dollar -denominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the date of such
refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been
exceeded so long as the principal amount of such refinancing Indebtedness does not exceed
the principal amount of such Indebtedness being refinanced.

     The principal amount of any Indebtedness incurred to refinance other Indebtedness, if
incurred in a different currency from the Indebtedness being refinanced, shall be calculated
based on the currency exchange rate applicable to the currencies in which such respective
Indebtedness is denominated that is in effect on the date of such refinancing.

     (e) The Issuer shall not, and shall not permit any Subsidiary Guarantor to directly or
indirectly, incur any Indebtedness (including Acquired Indebtedness) that is subordinated or
junior in right of payment to any Indebtedness of the Issuer or such Subsidiary Guarantor,
as the case may be, unless such Indebtedness is expressly subordinated in right of payment
to the Notes or such Subsidiary Guarantor’s guarantee to the extent and in the same manner
in all material respects and taken as a whole as such Indebtedness is subordinated in right
of payment to other Indebtedness of the Issuer or such Subsidiary Guarantor as the case may
be.

     (f) (1) Unsecured Indebtedness shall not be treated as subordinated or junior to
secured Indebtedness merely because it is unsecured and (2) Senior Indebtedness shall not be
treated as subordinated or junior to any other Senior Indebtedness merely because it has a
junior priority with respect to the same collateral or is secured by different collateral.

          SECTION 1012. Limitation on Liens.

          From and after the Escrow Release Date, the Issuer shall not, and shall not permit any of its
Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become
effective any Lien that secures obligations under any Indebtedness or any related Guarantees (the
“Initial Lien”) of any kind upon any of their property or assets, now owned or hereafter acquired,
except:

     (1) in the case of Initial Liens on any Collateral owned by a Spectrum Entity, any
Initial Lien if such Initial Lien is of the type described under clauses (1), (2), (3), (4),
(7), (8), (9), (14), (16), (17), (18) (but only to the extent the original Lien being
refinanced is listed in this clause (1)), (19), (20), (21), (22), (24), (25), (26), (27),
(30) or (31) of the definition of “Permitted Liens” (Liens permitted by such clauses
“Permitted Spectrum Liens”); and

     (2) in the case of any other asset or property owned by the Company or a Restricted
Subsidiary (other than a Spectrum Entity), any Initial Lien if (i) in the case of any asset
that is not at the time Collateral the Notes are equally and ratably secured with (or on a
senior basis to, in the case such Initial Lien secures any Subordinated Indebtedness) the
obligations secured by such Initial Lien or (ii) such

-92-

 

Initial Lien is expressly junior in
ranking on Collateral relative to the Notes and guarantees pursuant to an Intercreditor
Agreement or such Initial Lien is a Permitted Lien,

          Any Lien created for the benefit of the Holders of the Notes pursuant to clause (2) of the
preceding paragraph shall provide by its terms that such Lien shall be automatically and
unconditionally released and discharged upon the release and discharge of the Initial Lien which
release and discharge in the case of any sale of any such asset or property shall not affect any Lien
that the Existing Secured Notes Collateral Agent may have on the proceeds from such sale.

          SECTION 1013. Limitations on Transactions with Affiliates.

          From and after the Escrow Release Date:

     (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, make any
payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets
to, or purchase any property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of,
any Affiliate of the Issuer (each of the foregoing, an “Affiliate Transaction”) involving
aggregate payments or consideration in excess of $10.0 million, unless:

     (1) such Affiliate Transaction is on terms that are not materially less
favorable to the Issuer or the relevant Restricted Subsidiary than those that would
have been obtained in a comparable transaction by the Issuer or such Restricted
Subsidiary with an unrelated Person; and

     (2) the Issuer deliver to the Trustee (i) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate payments
or consideration in excess of $25.0 million, a resolution adopted by the majority of
the Board of Directors approving such Affiliate Transaction and set forth in an
Officers’ Certificate certifying that such Affiliate Transaction complies with
clause (1) above; and (ii) with respect to any Affiliate Transactions or series of
related Affiliate Transactions involving aggregate payments or consideration in
excess of $75.0 million, a letter from an Independent Financial Advisor stating that
such transaction is fair to the Issuer or such Restricted Subsidiary from a
financial point of view or meets the requirements of clause (a) of the preceding
paragraph.

          (b) The foregoing provisions shall not apply to the following:

     (1) transactions between or among the Issuer and/or any of the Restricted
Subsidiaries;

     (2) Restricted Payments permitted by Section 1010 and the definition of
“Permitted Investments”;

     (3) the payment of reasonable fees and compensation paid to, and indemnities
provided on behalf of, officers, directors, employees or consultants of the Issuer,
any of its direct or indirect parents or any Restricted Subsidiary;

     (4) transactions in which the Issuer or any Restricted Subsidiary, as the case
may be, delivers to the Trustee a letter from an Independent Financial Advisor

of equity;

     provided that this Section 1015(a) shall not be applicable to any guarantee of any

provisions of this Indenture,

     (B) the release or discharge of the guarantee by such Restricted Subsidiary
which resulted in the creation of such Guarantee, except a discharge or release by
or as a result of payment under such guarantee,

     (C) if such Subsidiary Guarantor is designated as an Unrestricted Subsidiary or

first ceases to be a Restricted Subsidiary, respectively; or

     (D) if the Issuer exercises its legal defeasance option or its covenant
defeasance option as described under Article Thirteen hereof or if its obligations

     SECTION 1016. Limitation on Activities of Finance Co and Spectrum Entities.

     From and after the Escrow Release Date:

     (a) Notwithstanding anything to the contrary herein, no Spectrum Entity that is a

the net proceeds of such Indebtedness are not retained by the Finance Co, and (3) activities
incidental thereto. Neither the Issuer nor any Restricted Subsidiary shall engage in any
transactions with the Finance Co in violation of the immediately preceding sentence.

     SECTION 1017. Change of Control.

          (a) From and after the Escrow Release Date, if a Change of Control occurs, the Issuer shall
make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of
Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest, if any, to but excluding the date of purchase, subject to the right

at the address specified in the notice prior to the close of business on the third business
day preceding the Change of Control Payment Date;

     (6) Holders shall be entitled to withdraw their tendered Notes and their election to

purchase of the Notes through the facilities of DTC, subject to its rules and regulations.

          (c) The Issuer shall not be required to make a Change of Control Offer following a Change of

otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of

any other securities laws and regulations thereunder to the extent such laws or regulations are
applicable in connection with the repurchase of the Notes pursuant to a Change of Control Offer.

provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached
its obligations described in this Indenture by virtue thereof.

of the Change of Control Offer on or as soon as practicable after the Change of Control Payment
Date.

     SECTION 1018. Asset Sales.

          (a) From and after the Escrow Release Date, the Issuer shall not, and shall not permit any
Restricted Subsidiary to, cause or make an Asset Sale of any assets that do not constitute Spectrum
Assets, unless:

     (1) the Issuer or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market value (as
determined in good faith by the Company) of the assets sold or otherwise disposed of;

     (2) at least 75% of the consideration therefor received by the Issuer or such
Restricted Subsidiary, as the case may be, is in the form of cash, Cash Equivalents or
Replacement Assets or a combination of the foregoing;

     (3) to the extent that any consideration received by the Issuer or a Restricted
Subsidiary in such Asset Sale constitutes securities or other assets that are of a type or
class that constitute Collateral, such securities or other assets, including the assets of
any Person that becomes a Subsidiary Guarantor as a

-99-

 

result of such transaction, are concurrently with their acquisition added to the Collateral securing the Notes in the manner
and to the extent required in this Indenture or any of the Security Documents; and

     (4) the Net Proceeds from any such Asset Sale of Collateral is paid directly by the
purchaser thereof to the Existing Secured Notes Collateral Agent to be held in trust in an
Asset Sale Proceeds Account for application in accordance with this Section 1018.

          Notwithstanding the foregoing provisions of the above paragraph, the Issuer and the Restricted
Subsidiaries shall not be required to cause any Net Proceeds to be held in an Asset Sale Proceeds
Account in accordance with Section 1018(a)(4) except to the extent the aggregate Net Proceeds from
all Asset Sales of Collateral which are not held in an Asset Sale Proceeds Account, or have not
been previously applied in accordance with the provisions of the following paragraphs relating to
the application of Net Proceeds from Asset Sales of Collateral, exceed $25.0 million.

          Within 365 days after the Issuer’s or a Restricted Subsidiary’s receipt of the Net Proceeds of
any Asset Sale covered by this Section 1018(a), the Issuer or such Restricted Subsidiary, at its
option, may apply the Net Proceeds from such Asset Sale:

     (1) to make one or more offers to the Holders of the Notes (and, at the option of the
Issuer, the holders of Other Pari Passu Lien Obligations) to purchase Notes (and such Other
Pari Passu Lien Obligations) pursuant to and subject to the conditions contained in this
Indenture (each, an “Asset Sale Offer”); provided, however, that if the Issuer or such
Restricted Subsidiary shall so reduce any Other Pari Passu Lien Obligations, the Issuer
shall make an offer to all Holders of Notes to purchase at a purchase price equal to 100% of
the principal amount thereof, plus accrued and unpaid interest and additional interest, if
any, the pro rata principal amount of the Notes, such offer to be conducted in accordance
with the procedures set forth below for an Asset Sale Offer but without any further
limitation in amount;

     (2) to an investment in (a) any one or more businesses; provided that such investment
in any business is in the form of the acquisition of Capital Stock such that it constitutes
a Restricted Subsidiary, (b) capital expenditures or (c) acquisitions of other assets, in
each of (a), (b) and (c), used or useful in a Similar Business;

     (3) to an investment in (a) any one or more businesses; provided that such investment
in any business is in the form of the acquisition of Capital Stock such that it constitutes
a Restricted Subsidiary, (b) properties or (c) other assets that, in each of (a), (b) and
(c), replace the businesses, properties and assets that are the subject of such Asset Sale;
or

     (4) to the extent such Net Proceeds are not from Asset Sales of Collateral, to
permanently reduce Indebtedness of a Restricted Subsidiary that is not a Subsidiary
Guarantor, other than Indebtedness owed to the Issuer, a Subsidiary Guarantor or another
Restricted Subsidiary.

          Pending the final application of any Net Proceeds from Asset Sales in accordance with clauses
(1) through (4) above that are not required to be held in an Asset Sale Proceeds Account, the
Issuer and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise apply such
Net Proceeds in any manner not prohibited by this Indenture. Any binding commitment to apply Net
Proceeds to invest in accordance with clauses (2) or (3) above shall be treated as a permitted
application of Net Proceeds so long as the Issuer or such Restricted Subsidiary enters into such
commitment with the good faith expectation that such Net Proceeds shall be applied to satisfy such
commitment within 180 days of such commitment; provided that if such commitment is later canceled
or terminated for any reason such Net Proceeds shall constitute “Excess Proceeds” (as defined
below). Any Net Proceeds from the Asset Sales covered by this clause (a) (together with any Net
Proceeds from Asset Sales covered by clause (a) of Section 1018 of the Existing Secured Notes
Indenture consummated before the Escrow Release Date) that are not invested or applied as provided
and within the time period described in the first sentence of the immediately preceding paragraph
(or the corresponding provision of the Existing Secured Notes Indenture, as the

-100-

 

case may be) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds
$50.0 million, the Issuer shall, make an Asset Sale Offer to all Holders of the Notes, and, at the
Issuer’s option to the holders of any Other Pari Passu Lien Obligations, to purchase the maximum
principal amount of Notes and such Other Pari Passu Lien Obligations, that are $2,000 or an
integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at
an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the date fixed for the closing of such offer, in accordance with the
procedures set forth in this Indenture. The Issuer shall commence an Asset Sale Offer with respect
to Excess Proceeds within ten business days after the date that Excess Proceeds exceeds $50.0
million by mailing the notice required pursuant to the terms of this Indenture, with a copy to the
Trustee. To the extent that the aggregate amount of Notes and such Other Pari Passu Lien
Obligations tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer
may use any remaining Excess Proceeds (“Unutilized Excess Proceeds”) for any purpose not prohibited
by the terms of this Indenture. If the aggregate principal amount of Notes or the Other Pari Passu
Lien Obligations surrendered by such holders thereof exceeds the amount of Excess Proceeds, the
Trustee shall select the Notes and the applicable agent or Issuer shall select such Other Pari
Passu Lien Obligations to be purchased on a pro
rata basis based on the accreted value or principal amount of the Notes or such Other Pari
Passu Lien Obligations tendered. Upon completion of any such Asset Sale Offer, the amount of
Excess Proceeds shall be reset at zero. After the Issuer or any Restricted Subsidiary has applied
the Net Proceeds from any Asset Sale of any Collateral as provided in, and within the time periods
required by, this paragraph (a), any Unutilized Excess Proceeds shall be released by the Existing
Secured Notes Collateral Agent to the Issuer or such Restricted Subsidiary for use by the Issuer or
such Restricted Subsidiary for any purpose not prohibited by the terms of this Indenture.

          (b) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly consummate an Asset Sale of Spectrum Assets unless:

     (1) the Issuer or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market value (as
determined in good faith by the Company) of the assets sold or otherwise disposed of;

     (2) 100% of the consideration therefor received by the Issuer or such Restricted
Subsidiary, as the case may be, is in the form of cash, Cash Equivalents or Replacement
Assets or a combination of the foregoing; and

     (3) to the extent that any consideration received by the Issuer and the Restricted
Subsidiaries in such Asset Sale constitute Replacement Assets such Replacement Assets
including the assets of any Person that becomes a Subsidiary Guarantor as a result of such
transaction, are concurrently with their acquisition added to the Collateral securing the
Notes in the manner and to the extent required in this Indenture or any of the Security
Documents.

          Within five Business Days after any Asset Sale of Spectrum Assets, the Company may designate
pursuant to an Officers’ Certificate all or a portion of the Net Proceeds therefrom for
reinvestment in the form of Replacement Assets (such Net Proceeds, “Specified Net Proceeds”).
Within 365 days after the Issuer’s or a Restricted Subsidiary’s receipt of Specified Net Proceeds,
the Issuer or such Restricted Subsidiary may apply such Specified Net Proceeds to purchase
Re-placement Assets; provided that during such 365 day period for reinvestments in Replacement
Assets such Specified Net Proceeds which are not used to purchase Replacement Assets shall be held
in the Asset Sale Proceeds Account and are only permitted to be withdrawn from such Asset Sale
Proceeds Account, within such 365 day reinvestment period, to pay the purchase price of any
Replacement Assets.

          Within 180 days after the Issuer’s or a Restricted Subsidiary’s receipt of Net Proceeds from
an Asset Sale of Spectrum Assets that are not designated Specified Net Proceeds (“Non-Specified Net
Proceeds”), the Issuer or such Restricted Subsidiary, at its option, may apply up to 25% of the
Non-Specified Net Proceeds from such Asset Sale of Spectrum Assets:

-101-

 

     (1) to make an investment in (a) any one or more businesses; provided that such
investment in any business is in the form of the acquisition of Capital Stock of such
business such that it constitutes a Restricted Subsidiary, (b) capital expenditures or (c)
acquisitions of other assets, in each of (a), (b) and (c), used or useful in a Similar
Business; provided, further, that, to the extent such investment is of the type which would
constitute Collateral under the Security Documents, such investment is concurrently added to
the Collateral securing the Notes in the manner and to the extent required in this Indenture
or any of the Security Documents; and/or

     (2) to make an investment in (a) any one or more businesses; provided that such
investment in any business is in the form of the acquisition of Capital Stock of such
business such that it constitutes a Restricted Subsidiary, (b) properties or (c) other
assets that, in each of (a), (b) and (c), replace the businesses, properties and assets that
are the subject of such Asset Sale; provided, further, that, to the extent such investment
is of the type which would constitute Collateral under the Security Documents, such
investment is concurrently added to the Collateral securing the Notes in the manner and to
the extent required in this Indenture or any of the Security Documents.

          The remainder of the Non-Specified Net Proceeds from an Asset Sale of Spectrum Assets covered
by this Section 1018(b) may be applied, at the option of the Issuer or such Restricted Subsidiary,
to purchase Replacement Assets within 180 days after the receipt by the Issuer or such Restricted
Subsidiary of the Non-Specified Net Proceeds from such Asset Sale of Spectrum Assets; provided that
during such 180 day period for reinvestments in Replacement Assets any such remaining portion of
the Non-Specified Net Proceeds from an Asset Sale of Spectrum Assets which are not used to purchase
Replacement Assets shall be held in the Asset Sale Proceeds Account and are only permitted to be
withdrawn from such Asset Sale Proceeds Account, within such 180 day reinvestment period, to pay
the purchase price of any Replacement Assets.

          Any Net Proceeds from Asset Sales of Spectrum Assets covered by this Section 1018(b) (together
with any Net Proceeds from Asset Sales of Spectrum Assets covered by clause (b) of Section 1018 of
the Existing Secured Notes Indenture consummated before the Escrow Release Date) that are not
invested or applied as provided and within the time period described above (or the corresponding
provision of the Existing Secured Notes Indenture) shall be deemed to constitute “Excess Spectrum
Assets Proceeds.” The Issuer may use Net Proceeds from Asset Sales of Spectrum Assets covered by
this clause (b) at any time to, to and when the aggregate amount of Excess Spectrum Assets Proceeds
exceeds $50.0 million the Issuer shall, make an offer to all Holders of the Notes, and, at the
Issuer’s option, to the holders of any Other Pari Passu Lien Obligations (a “Spectrum Assets Asset
Sale Offer”), to purchase the maximum principal amount of Notes and such Other Pari Passu Lien
Obligations, that is $2,000 or an integral multiple of $1,000 in excess thereof that may be
purchased out of the Excess Spectrum Assets Proceeds at an offer price in cash in an amount equal
to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date
fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture.
The Issuer shall commence a Spectrum Assets Asset Sale Offer with respect to Excess Spectrum
Assets Proceeds within ten business days after the date that Excess Spectrum Assets Proceeds
exceeds $50.0 million by mailing the notice required pursuant to the terms of this Indenture, with
a copy to the Trustee. To the extent that the aggregate amount of Notes and such Other Pari Passu
Lien Obligations tendered pursuant to a Spectrum Assets Asset Sale Offer is less than the Excess
Spectrum Assets Proceeds, the Issuer may use any remaining Excess Spectrum Assets Proceeds (which
shall also constitute “Unutilized Spectrum Assets Excess Proceeds”) for any purpose not prohibited
by the terms of this Indenture. If the aggregate principal amount of Notes or the Other Pari Passu
Lien Obligations surrendered by such holders thereof exceeds the amount of Excess Spectrum Assets
Proceeds, the Trustee shall select the Notes and the applicable agent or Issuer shall select such
Other Pari Passu Lien Obligations to be purchased on a pro rata basis based on the accreted value
or principal amount of the Notes or such Other Pari Passu Lien Obligations tendered. Upon
completion of any such Spectrum Assets Asset Sale Offer, the amount of Excess Spectrum Assets
Proceeds shall be reset at zero. After the Issuer or any Restricted Subsidiary has applied the Net
Proceeds from any Asset Sale of Spectrum Assets as provided in, and within the time periods
required by, this paragraph (b), any Unutilized Spectrum Assets Excess Proceeds shall be released
by the Collateral Agent to the Issuer or such Restricted Subsidiary for use by the Issuer or such
Restricted Subsidiary for any purpose not prohibited by this Indenture.

          (c) For purposes of Section 1018(a) and (b), (i) any liabilities (other than Other Pari Passu
Lien Obligations and Indebtedness the repayment of which would constitute a Restricted Payment) (as
shown on the Issuer’s, or such Restricted Subsidiary’s, most recent balance sheet or in the Notes
thereto) of the Issuer or any Restricted Subsidiary that are assumed by the transferee of any such
assets and for which the Issuer and all Restricted Subsidiaries have been validly released by all
creditors in writing; and (ii) any securities or other obligations received by the Issuer, a
Subsidiary Guarantor or such Restricted Subsidiary from such transferee that are converted by the
Issuer or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or
Cash Equivalents received) within 180 days following the closing of such Asset Sale shall be deemed
to be cash or Cash Equivalents.

          (d) In addition for purposes of Section 1018(a),
any Designated Noncash Consideration received
by the Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate fair market
value, taken together with all other Designated Noncash Consideration received pursuant to this
clause (c) that is at that time outstanding, not to exceed $200.0 million, with the fair market
value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in
value, shall be deemed to be cash or Cash Equivalents.

          (e) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws or regulations are
applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer or
Spectrum Assets Asset Sale Offer. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Indenture, the Issuer shall comply with the
applicable securities laws and regulations and shall not be deemed to have breached its obligations
described in this Indenture by virtue thereof.

     SECTION 1019. [INTENTIONALLY DELETED].

     SECTION 1020. Further Assurances and After-Acquired Property.

          From and after the Escrow Release Date and the Assumption, with respect to Collateral, and
from and after the Issue Date and until the Escrow Release Date with respect to Escrow Collateral:

          (a) To the extent required under this Indenture or any of the Security Documents, the Issuer
and the Subsidiary Guarantors shall execute any and all further documents, financing statements,
agreements and instruments, and take all further action that may be required under applicable law,
or that the Collateral Agent may reasonably request, in order to grant, preserve, protect and
perfect the validity and priority of the security interests and Liens created or intended to be
created by the Security Documents in the Collateral. In addition, to the extent required under
this Indenture or any of the Security Documents, from time to time, the Issuer shall promptly
secure the obligations under this Indenture, Security Documents and Intercreditor Agreement by
pledging or creating, or causing to be pledged or created, perfected security interests and Liens
with respect to the Collateral perfected to the extent required by the Security Documents. Such
security interests and Liens shall be created under the Security Documents and other security
agreements and other instruments and documents in form and substance reasonably satisfactory to the
Trustee, and the Issuer shall deliver or cause to be delivered to Trustee all such instruments and
documents (including certificates, legal opinions, title insurance policies and lien searches) as
the Trustee shall reasonably request to evidence compliance with this covenant. The Issuer agrees
to provide such evidence as the Trustee shall reasonably request as to the perfection (to the
extent required by the Security Documents) and priority status of each such security interest and
Lien.

          (b) In furtherance of the foregoing, promptly following the acquisition by the Issuer or any
Subsidiary Guarantor of any After-Acquired Property, to the extent such After-Acquired Property is
of the type which would constitute Collateral under the Security Documents, the Issuer or
such Subsidiary Guarantor shall execute and deliver such deeds of trust, security instruments,
financing statements and certificates and opinions of counsel as shall be reasonably necessary to
cause such After-Acquired Property to be made subject to the Lien under the Security Documents in
the manner and to the extent required by this Indenture or any of the Security Documents

-103-

 

and shall take all necessary action so that such Lien is perfected to the extent required by the Security
Documents to vest in the Existing Secured Notes Collateral Agent a perfected security
interest in such After-Acquired Property and to have such After-Acquired Property added to the
Collateral and thereupon all provisions of this Indenture and the Security Documents relating to
the Collateral shall be deemed to relate to such After-Acquired Property to the same extent and
with the same force and effect.

          SECTION 1021. Information Regarding Collateral.

          (a) The Issuer shall furnish to the Collateral Agent and the Existing Secured Notes Collateral
Agent, with respect to the Issuer or any Subsidiary Guarantor (from and after the Issue Date in
case of the Issuer and from and after the Assumption in the case of any Subsidiary Guarantor),
promptly (and in any event within 30 days of such change) written notice of any change in such
Person’s (i) name, (ii) jurisdiction of organization or formation, (iii) identity or corporate
structure or (iv) Organizational Identification Number. The Issuer and the Subsidiary Guarantors
shall agree not to effect or permit any change referred to in the preceding sentence unless all
filings have been made under the Uniform Commercial Code or otherwise that are required in the Security
Documents or Escrow Agreement in order for the Collateral (including Escrow Collateral prior to the
Escrow Release Date) to be made subject to the Lien of the Existing Secured Notes Collateral Agent
under the Security Documents or the Trustee under the Escrow Agreement in the manner and to the
extent required by this Indenture or any of the Security Documents and shall take all necessary
action so that such Lien is perfected with the same priority as immediately prior to such change to
the extent required by the Security Documents. The Issuer also agrees promptly to notify the
Collateral Agent and the Existing Secured Notes Collateral Agent if any material portion of the
Collateral is damaged, destroyed or condemned.

          (b) Each year, within 120 days after the end of the preceding fiscal year, the Issuer shall
deliver to the Trustee a certificate of a financial officer setting forth the information required
pursuant to the schedules required by the Security Documents or confirming that there has been no
change in such information since the date of the prior annual financial statements.

     SECTION 1022. Impairment of Security Interest.

          Upon the consummation of the Assumption, subject to the rights of the holders of Permitted
Liens, the Company shall not, and shall not permit any of its Restricted Subsidiaries to, take or
knowingly or negligently omit to take, any action which action or omission would reasonably be
expected to have the result of materially impairing the security interest with respect to the
Collateral for the benefit of Secured Parties, subject to limited exceptions. The Company shall
not amend, modify or supplement, or permit or consent to any amendment, modification or supplement
of, the Security Documents in any way that would be adverse to the Holders of the Notes in any
material respect, except as permitted by Article Nine or Fourteen, the Security Documents or the
Intercreditor Agreement.

     SECTION 1023. Limitation on Lines of Business.

          From and after the Escrow Release Date, the Issuer shall not, and shall not permit any
Restricted Subsidiary to, engage in any business other than a Similar Business.

     SECTION 1024. Future Subsidiary Guarantors.

          From and after the Escrow Release Date, the Issuer shall cause each Spectrum Entity that is a
wholly-owned Domestic Subsidiary that is formed or acquired following the Escrow Release Date to
execute and deliver to the Trustee a supplemental indenture pursuant to which such domestic
wholly-owned Restricted Subsidiary will unconditionally Guarantee, on a joint and several basis,
the full and prompt payment of the principal of, premium, if any, and interest in respect of the
Notes on a senior secured basis and all other obligations under this Indenture.

-104-

 

          Each Restricted Subsidiary that becomes a Subsidiary Guarantor on or after the Escrow Release
Date shall also become a party to the applicable Security Documents and shall as promptly as
practicable execute and deliver such security instruments, financing statements and certificates
and opinions of counsel (to the extent, and substantially in the form, delivered on the Escrow
Release Date (but no greater scope)) as may be necessary to vest in the Existing Secured Notes
Collateral Agent a first-priority security interest (subject to Permitted Liens or Permitted
Spectrum Liens in the case of Spectrum Assets) in the manner and to the extent set forth in the
Security Documents and this Indenture in properties and assets of the type constituting Collateral
as security for the Notes or the Guarantees, and thereupon all provisions of this Indenture
relating to the Collateral shall be deemed to relate to such properties and assets to the same
extent and with the same force and effect.

     SECTION 1025. Suspension of Certain Covenants.

          (a) During any period of time following the Escrow Release Date that: (i) the Notes have
Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is
continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii)
being collectively referred to as a “Covenant Suspension Event”), the Issuer and the Restricted
Subsidiaries shall not be subject to 1010, 1011, 1013, 1014, 1015, 1016, 1024 hereof, and clause
(4) of Section 801 hereof (the “Suspended Covenants”).

          (b) In the event that the Issuer and the Restricted Subsidiaries are not subject to the
Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and
on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their
Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade
Rating then the Issuer and the Restricted Subsidiaries shall thereafter again be subject to the
Suspended Covenants under this Indenture. The period of time between the Covenant Suspension
Event and the Reversion Date is referred to herein as the “Suspension Period”.

          (c) On each Reversion Date, all Indebtedness incurred, or Disqualified Stock or preferred
stock issued, during the Suspension Period will be classified as having been incurred or issued
pursuant to Section 1011(a) or one of the clauses set forth in Section 1011(b) (to the extent
such Indebtedness or Disqualified Stock or preferred stock would be permitted to be incurred or
issued thereunder as of the Reversion Date and after giving effect to Indebtedness incurred or
issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such
Indebtedness or Disqualified Stock or preferred stock would not be so permitted to be incurred or
issued pursuant to the Section 1011(a) or Section 1011(b), such Indebtedness or Disqualified
Stock or preferred stock will be deemed to have been outstanding on the Existing Secured Notes
Issue Date, so that it is classified as permitted under Section 1011(b)(2). Calculations made
after the Reversion Date of the amount available to be made as Restricted Payments under Section
1010 will be made as though Section 1010 had been in effect since the Existing Secured Notes
Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the
Suspension Period will reduce the amount available to be made as Restricted Payments under the
Section 1010(b). As described above, however, no Default or Event of Default will be deemed to
have occurred as a result of the Reversion Date occurring on the basis of any actions taken or
the continuance of any circumstances resulting from actions taken or the performance of
obligations under agreements entered into by the Issuer or any of the Restricted Subsidiaries
during the Suspension Period (other than agreements to take actions after the Reversion Date that
would not be permitted outside of the Suspension Period entered into in contemplation of the
Reversion Date). For purposes of Section 1018, on the Reversion Date, the unutilized Excess
Proceeds and the Excess Spectrum Asset Proceeds amounts will be reset to zero.

          (d) During the Suspension Period no Restricted Subsidiary may be designated as an
Unrestricted Subsidiary.

          (e) The Issuer shall deliver promptly to the Trustee an Officer’s Certificate notifying it
of any Covenant Suspension Event or Reversion Date, under this Section 1025.

     SECTION 1026. Activities of Escrow Issuer Prior to the Assumption.

          Prior to the Assumption, the Escrow Issuer’s activities are restricted to issuing the Notes,
issuing Capital Stock to, and receiving capital contributions from, the Company, performing its
obligations in respect of the Notes under this Indenture and the Escrow Agreement, and consummating
the Assumption and redeeming the Redemption Amount of Notes on the Conditions Precedent Date, if
applicable, and conducting such other activities as are necessary or appropriate to carry out the
activities described above. Prior to the Assumption, the Escrow Issuer shall not issue any debt
other than the Notes, own, hold or otherwise have any interest in any assets other than the Escrow
Account and cash or Cash Equivalents.

     SECTION 1027. Escrow of Gross Proceeds

          (a) Concurrently with the closing of the offering of the Notes, the Escrow Issuer, the
Company, the Trustee and the Escrow Agent shall enter into the Escrow Agreement and in connection
therewith the Initial Purchaser will deposit the gross proceeds (such gross proceeds reflecting the principal
amount net of original issue discount) of the offering into an Escrow Account, which will include
an amount sufficient to yield the aggregate Escrow Redemption Price on the Conditions Precedent
Date for $380 million aggregate principal amount of the Notes (the “Redemption Amount”). The Escrow
Issuer will grant the Trustee, for the benefit of the Holders, a first priority security interest
in the Escrow Account and all deposits therein to secure the Obligations under the Notes pending
disbursement as described below.

          (b) Certain funds held in the Escrow Account will be released to the Issuer in accordance with
the Escrow Agreement upon delivery by the Escrow Issuer to the Escrow Agent and the Trustee of an
Officers’ Certificate certifying that, prior to or concurrently with the release of funds from the
Escrow Account (clauses (1) through (3) below, collectively, the “Escrow Conditions”):

     (1) (i) the Company shall designate the Notes and Guarantees as “Other Pari Passu Lien
Obligations” in accordance with Section 7.19 of the Security Agreement (the “Other Pari
Passu Lien Obligations Certificate”) and (ii) the Collateral Agent shall execute an “Other
Pari Passu Lien Secured Party Consent” (as defined in the Security Agreement, the
“Consent Agreement”) whereby it shall become party to the Security Agreement as an
Authorized Representative and whereby the Existing Secured Notes Collateral Agent shall hold
the Collateral for the benefit of the Trustee, the Collateral Agent, the Holders and other
Secured Parties, and the Notes will be secured on a first priority basis, subject to
Permitted Liens, by Liens on the Collateral;

     (2) the Assumption will be consummated; and

     (3) the Second Investment Closing has been consummated.

          (c) The date upon which the funds are to be released from the Escrow Account in accordance
with Section 1027(b) and the Escrow Agreement shall be herein referred to as the “Escrow Release
Date.”

the portion of the principal amount thereof that has been or is to be purchased or redeemed.

          A new Note in principal amount equal to the unpurchased or unredeemed portion of any Note

          Notice of redemption shall be given in the manner provided for in Section 106 not less than 30

each such Note, or the portion thereof, to be redeemed, and that interest thereon will cease
to accrue on and after said date,

the Issuer or, at the Issuer’s request, by the Trustee in the name and at the expense of the
Issuer.

          SECTION 1106. Deposit of Redemption Price.

          Prior to any Redemption Date, the Issuer shall deposit with the Trustee or with a Paying Agent
(or, if the Issuer are acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money sufficient to pay the Redemption Price of, and accrued interest,
if any, on, all the Notes which are to be redeemed on that date.

          SECTION 1107. Notes Payable on Redemption Date.

          Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein specified (together with
accrued interest, if any, to the Redemption Date)(except as provided in Section 1101(e)), and from
and after such date (unless the Issuer shall default in the payment of the Redemption Price and
accrued interest) such Notes shall cease to bear interest. Upon surrender of any such Note for
redemption in accordance with said notice, such Note shall be paid by the Issuer at the Redemption
Price, together with accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the
close of business on the relevant Record Dates according to their terms and the provisions of

          SECTION 1108. Notes Redeemed in Part.

          Any Note which is to be redeemed only in part (pursuant to the provisions of this Article)
shall be surrendered at the office or agency of the Issuer maintained for such purpose pursuant to
Section 1002 (with, if the Issuer or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the
Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuer shall execute,
and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a
new Note or Notes, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the principal of the Note
so surrendered.

          SECTION 1109. Special Mandatory Redemption. 

          In the event that upon the earlier of (x) the date on which the Issuer determines in its sole
discretion that the Escrow Conditions cannot be satisfied and (y) June 9, 2010 (the date in clause
(x) or (y), the “Conditions Precedent Date”), the officer’s certificate attached to the Escrow
Agreement as Exhibit A and required to be delivered to the Escrow Agent and the Trustee for release
of funds from the Escrow Account remains undelivered, the Issuer will be required to redeem the
Redemption Amount of Notes on the Conditions Precedent Date at the Escrow Redemption Price and the
Assumption shall be consummated with respect to the remaining
$540 million in aggregate principal amount of Notes. In accordance with the provisions of the Escrow Agreement, funds will be released
from the Escrow Account to pay certain amounts to the Escrow Agent, pay the initial purchaser’s
Deferred Discount (as defined in the Escrow Agreement) and make the redemption, and any remaining funds
held in the Escrow Account will be released to the Company in connection with the Assumption. If
Notes are to be redeemed in accordance with this Section 1109, the Trustee shall select the Notes
to be redeemed on a pro rata basis based on the principal amount of Notes outstanding. If Notes are
redeemed in accordance with this Section 1109 and the Company and Finance Co default in their
obligation to assume the remaining $540 million in aggregate principal

-109-

 

 amount of Notes, such Notes
shall become immediately due and payable, in which case none of the funds in the Escrow Account
will be released to the Issuer and certain of such funds will instead be used by the Trustee to
satisfy the Obligations under the Notes and the Indenture in accordance with the Escrow Agreement.

          The selection of the Redemption Amount of Notes for redemption on the Conditions Precedent
Date shall be made by the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which such Notes are listed, or, if such Notes are not so listed,
on a pro rata basis or by lot or such similar method in accordance with the procedures of DTC.

ARTICLE TWELVE

GUARANTEES

          SECTION 1201. Guarantees.

          On the Escrow Release Date, each of the Issuer’s direct and indirect Restricted Subsidiaries
that are Domestic Subsidiaries on the Escrow Release Date that guarantee the Existing Secured Notes
shall, by execution of a supplemental indenture on the Escrow Release Date, become a Subsidiary
Guarantor. Each Subsidiary Guarantor hereby jointly and severally, unconditionally and irrevocably
guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each
Holder of a Note authenticated and delivered by the Trustee, and to the Trustee on behalf of such
Holder, that: (a) the principal of (and premium, if any) and interest on the Notes will be paid in
full when due, whether at Stated Maturity, by acceleration or otherwise (including, without
limitation, the amount that would become due but for the operation of the automatic stay under
Section 362(a) of the Bankruptcy Law), together with interest on the overdue principal, if any, and
interest on any overdue interest, to the extent lawful, and all other obligations of the Issuer to
the Holders, Collateral Agent or the Trustee hereunder or thereunder will be paid in full or
performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of
time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in
full when due or performed in accordance with the terms of the extension or renewal, whether at
Stated Maturity, by acceleration or otherwise, subject, however, in the case of clauses (a) and (b)
above, to the limitation described in Section 1205 hereof.

          Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, any release of any other Subsidiary Guarantor, the recovery of any
judgment against the Issuer, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor.

          Each Subsidiary Guarantor hereby waives (to the extent permitted by law) the benefits of
diligence, presentment, demand for payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer
or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of
such Subsidiary Guarantor shall not be discharged as to any Note except by complete performance of
the obligations contained in such Note, this Indenture and such Guarantee. Each Subsidiary
Guarantor acknowledges that the Guarantee is a guarantee of payment and not of collection. Each of
the Subsidiary Guarantors hereby agrees that, in the event of a default in payment of principal (or
premium, if any) or interest on such Note, whether at its Stated Maturity, by acceleration,
purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the
Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly
against each of the Subsidiary Guarantors to enforce such Subsidiary Guarantor’s Guarantee without first proceeding against the Issuer or any other Subsidiary
Guarantor. Each Subsidiary Guarantor agrees that if, after the occurrence and during the
continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable
law from exercising their respective rights to accelerate the Maturity of the Notes, to collect
interest on the Notes, or to enforce or exercise any other right or remedy with respect to the
Notes, such Subsidiary Guarantor shall pay to the Trustee for the account of the Holder, upon demand

-110-

 

therefor, the amount that would otherwise have been due and payable had such rights and
remedies been permitted to be exercised by the Trustee or any of the Holders.

          If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or
any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in
relation to either the Issuer or any Subsidiary Guarantor, any amount paid by any of them to the
Trustee or such Holder, the Guarantee of each of the Subsidiary Guarantors, to the extent
theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor
further agrees that, as between each Subsidiary Guarantor, on the one hand, and the Holders and the
Trustee on the other hand, (x) subject to this Article Twelve, the Maturity of the obligations
guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of the
Guarantee of such Subsidiary Guarantor notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event
of any acceleration of such obligation as provided in Article Five hereof, such obligations
(whether or not due and payable) shall forthwith become due and payable by each Subsidiary
Guarantor for the purpose of the Guarantee of such Subsidiary Guarantor.

          Each Guarantee shall remain in full force and effect and continue to be effective should any
petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer
becomes insolvent or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Issuer’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if
at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or
reduced in amount, or must otherwise be restored or returned by any obligee on the Notes, whether
as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or
performance had not been made. In the event that any payment or any part thereof, is rescinded,
reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be
reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

          SECTION 1202. Severability.

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

          SECTION 1203. Restricted Subsidiaries.

          The Issuer shall cause any Restricted Subsidiary required to guarantee payment of the Notes
pursuant to the terms and provisions of Section 1015 or the first sentence of Section 1201 to (i)
execute and deliver to the Trustee any amendment or supplement to this Indenture in accordance with
the provisions of Article Nine or Section 1027(b)(2) of this Indenture pursuant to which such
Restricted Subsidiary shall guarantee all of the obligations on the Notes, whether for principal,
premium, if any, interest (including interest accruing after the filing of, or which would have
accrued but for the filing of, a petition by or against the Issuer under Bankruptcy Law, whether or
not such interest is allowed as a claim after such filing in any proceeding under such law) and
other amounts due in connection therewith (including any fees, expenses and indemnities), on a
senior secured basis, (ii) deliver to such Trustee an Opinion of Counsel reasonably satisfactory to
such Trustee to the effect that such amendment or supplement has been duly executed and delivered
by such Restricted Subsidiary and is in compliance with the terms of this Indenture and (iii)
execute and deliver a supplement or such comparable documentation to become a grantor to the
Security Agreement and the other Security Documents and to take all actions to cause the Lien
created by the Security Documents to be duly perfected to the extent required by such agreement.
Upon the execution of any such amendment or supplement, the obligations of the Subsidiary
Guarantors and any such Restricted Subsidiary under their respective Guarantees shall become joint
and several and each reference to the “Subsidiary Guarantor” in this Indenture shall, subject to Section 1208, be deemed to refer to all Subsidiary Guarantors,
including such Restricted Subsidiary. Such Guarantee shall be released in accordance with Section
803 and Section 1015(b).

-111-

 

          SECTION 1204. Ranking of Guarantee.

          The Guarantee issued by any Subsidiary Guarantor shall be a senior obligation of such
Subsidiary Guarantor and will be secured by a first-priority lien on the Collateral owned by such
Subsidiary Guarantor. The Guarantees shall (a) rank equally in right of payment with all existing
and future Senior Indebtedness of the Subsidiary Guarantor, (b) be senior in right of payment to
all existing and future Subordinated Indebtedness of each Subsidiary Guarantor, and (c) be
structurally subordinated to Indebtedness and other liabilities of Subsidiaries of such Subsidiary
Guarantor that do not Guarantee the Notes.

          SECTION 1205. Limitation of Subsidiary Guarantors’ Liability.

          Each Subsidiary Guarantor and by its acceptance hereof each Holder confirms that it is the
intention of all such parties that the guarantee by each such Subsidiary Guarantor pursuant to its
Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law,
the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal
or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To
effectuate the foregoing intention, the Holders and each such Subsidiary Guarantor hereby
irrevocably agree that the obligations of such Subsidiary Guarantor under its Guarantee shall be
limited to the maximum amount that will not, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of
such other Subsidiary Guarantor under its Guarantee or pursuant to this Section 1205, result in the
obligations of such Subsidiary Guarantor under its Guarantee constituting such fraudulent transfer
or conveyance.

          SECTION 1206. Contribution.

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

          SECTION 1207. Subrogation.

          Each Subsidiary Guarantor shall be subrogated to all rights of Holders against the Issuer in
respect of any amounts paid by any Subsidiary Guarantor pursuant to the provisions of Section 1201;
provided, however, that, if an Event of Default has occurred and is continuing, no Subsidiary
Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such
right of subrogation until all amounts then due and payable by the Issuer under this Indenture or
the Notes shall have been paid in full.

-112-

 

          SECTION 1208. Reinstatement.

          Each Subsidiary Guarantor hereby agrees (and each Person who becomes a Subsidiary Guarantor
shall agree) that the Guarantee provided for in Section 1201 shall continue to be effective or be
reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or
interest thereon is rescinded or must otherwise be restored by a Holder to the Issuer upon the
bankruptcy or insolvency of the Issuer or any Subsidiary Guarantor.

          SECTION 1209. Release of a Subsidiary Guarantor.

          Concurrently with the discharge of the Notes under Section 401, the Legal Defeasance of the
Notes under Section 1302 hereof, or the Covenant Defeasance of the Notes under Section 1303 hereof,
the Subsidiary Guarantors shall be released from all their obligations under their Guarantees under
this Article Twelve. Any Subsidiary Guarantor shall be released from all its obligations under its Guarantee in
accordance with Section 803 and Section 1015(b).

          SECTION 1210. Benefits Acknowledged.

          Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by this Indenture and from its guarantee and waivers
pursuant to its Guarantees under this Article Twelve.

ARTICLE THIRTEEN

DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 1301. Issuer’s Option to Effect Legal Defeasance or Covenant Defeasance.

          The Issuer may, at its option by Board Resolution, at any time, with respect to the Notes,
elect to have either Section 1302 or Section 1303 be applied to all Outstanding Notes upon
compliance with the conditions set forth below in this Article Thirteen.

          SECTION 1302. Legal Defeasance and Discharge.

          Upon the Issuer’s exercise under Section 1301 of the option applicable to this Section 1302,
the Issuer and the Subsidiary Guarantors shall be deemed to have been discharged from its
respective obligations with respect to all Outstanding Notes on the date the conditions set forth
in Section 1304 are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal
Defeasance means that the Issuer and the Subsidiary Guarantors shall be deemed to have paid and
discharged the entire indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be “Outstanding” only for the purposes of Section 1305 and the other Sections of this
Indenture referred to in (A) and (B) below, and to have satisfied all its other obligations under
such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense
of the Issuer, shall execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder: (A) the rights of Holders
of Outstanding Notes to receive payments in respect of the principal of (and premium, if any, on)
and interest on such Notes when such payments are due, solely out of the trust described in Section
1304, (B) the Issuer’s obligations with respect to such Notes under Sections 304, 305, 306, 1002
and 1003, (C) the rights, powers, trusts, duties, indemnities and immunities of the Trustee and
Collateral Agent hereunder, and the obligations of the Issuer’s and the Subsidiary Guarantors’
obligations in connection therewith and (D) this Article Thirteen. Subject to compliance with this
Article Thirteen, the Issuer may exercise its option under this Section 1302 notwithstanding the
prior exercise of its option under Section 1303 with respect to the Notes.

-113-

 

          SECTION 1303. Covenant Defeasance.

          Upon the Issuer’s exercise under Section 1301 of the option applicable to this Section 1303,
the Issuer and the Subsidiary Guarantors shall be released from its respective obligations under
any covenant contained in Sections 801, 802 and in Sections 1005, 1006, 1007, 1009 through 1022
with respect to the Outstanding Notes on and after the date the conditions set forth below are
satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not to be
“Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders
(and the consequences of any thereof) in connection with such covenants, but shall continue to be
deemed “Outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance
means that, with respect to the Outstanding Notes, the Issuer or any Subsidiary Guarantor, as
applicable, may omit to comply with and shall have no liability in respect of any term, condition
or limitation set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Sections 501(3), 501(4), 501(5) and 501(7) and,
with respect to only any Significant Subsidiary and not the Issuer, Section 501(6), but, except as specified
above, the remainder of this Indenture and such Notes shall be unaffected thereby.

          SECTION 1304. Conditions to Legal Defeasance or Covenant Defeasance.

          The following shall be the conditions to application of either Section 1302 or Section 1303 to
the Outstanding Notes:

     (1) The Issuer shall irrevocably have deposited or caused to be deposited with the
Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to
comply with the provisions of this Article Thirteen applicable to it) as trust funds in
trust for the purpose of making the following payments, specifically pledged as security
for, and dedicated solely to the benefit of the Holders of such Notes; (A) cash in U.S.
dollars, or (B) non-callable Government Securities, or (C) a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee, to
pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee)
to pay and discharge, the principal of (and premium, if any) and interest on the Outstanding
Notes on the Stated Maturity (or Redemption Date, if applicable) of such principal (and
premium, if any or, interest due on the Notes; provided that the Trustee shall have been
irrevocably instructed to apply such cash or the proceeds of such Government Securities to
said payments with respect to the Notes. Before such a deposit, the Issuer may give to the
Trustee, in accordance with Section 1103 hereof, a notice of its election to redeem all of
the Outstanding Notes at a future date in accordance with Article Eleven hereof, which
notice shall be irrevocable. Such irrevocable redemption notice, if given, shall be given
effect in applying the foregoing;

     (2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an
Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that, subject to customary assumptions and exclusions,

     (A) the Issuer has received from, or there has been published by, the United
States Internal Revenue Service a ruling, or

     (B) since the issuance of the Notes, there has been a change in the applicable
U.S. Federal income tax law, in either case to the effect that, and based thereon
such Opinion of Counsel in the United States shall confirm that, subject to
customary assumptions and exclusions, the Holders of the Outstanding Notes will not
recognize income, gain or loss for U.S. Federal income tax purposes as a result of
such Legal Defeasance and will be subject to U.S. Federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance had not occurred;

-114-

 

     (3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee
an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming
that, subject to customary assumptions and exclusions, the Holders of the Outstanding Notes
will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of
such Covenant Defeasance and will be subject to U.S. Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred;

     (4) no Default or Event of Default (other than that resulting from borrowing funds to
be applied to make such deposit and the granting of Liens in connection therewith) shall
have occurred and be continuing on the date of such deposit;

     (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default (other than that resulting from borrowing funds to be
applied to make such deposit) under any other material agreement or instrument (other than this Indenture) to
which, the Issuer or any Subsidiary Guarantor is a party or by which the Issuer or any
Subsidiary Guarantor is bound;

     (6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect
that, as of the date of such opinion and subject to customary assumptions and exclusions
following the deposit, the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally
under any applicable U.S. Federal or state law;

     (7) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating
that the deposit was not made by the Issuer with the intent of defeating, hindering,
delaying or defrauding any creditors of the Issuer or any Subsidiary Guarantor or others;
and

     (8) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel in the United States (which Opinion of Counsel may be subject to
customary assumptions and exclusions) each stating that all conditions precedent provided
for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have
been complied with.

          SECTION 1305. Deposited Money and Government Securities to Be Held in Trust; Other
Miscellaneous Provisions.

          Subject to the provisions of the last paragraph of Section 1003, all cash and Government
Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee, collectively for purposes of this Section 1305, the “Trustee”) pursuant to Section 1304 in
respect of the Outstanding Notes shall be held in trust and applied by the Trustee, in accordance
with the provisions of such Notes and this Indenture, to the payment, either directly or through
any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due thereon in respect of
principal (and premium, if any) and interest, but such money or Government Securities need not be
segregated from other funds except to the extent required by law.

          The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the Government Securities deposited pursuant to Section 1304 or the principal
and interest received in respect thereof other than any such tax, fee or other charge which by law
is for the account of the Holders of the Outstanding Notes.

          Anything in this Article Thirteen to the contrary notwithstanding, the Trustee shall deliver
or pay to the Issuer from time to time upon Issuer Request any money or Government Securities held
by it as provided in Section 1304 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be deposited to effect
an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this
Article.

-115-

 

          SECTION 1306. Reinstatement.

          If the Trustee or any Paying Agent is unable to apply any money or Government Securities in
accordance with Section 1305 by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s and
each Subsidiary Guarantor’s obligations under this Indenture and the Outstanding Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the
case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or
Government Securities in accordance with Section 1305; provided, however, that if the Issuer makes
any payment of principal of (or premium, if any) or interest on any Note following the
reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or Government Securities held by the Trustee or
Paying Agent.

ARTICLE FOURTEEN

SECURITY

          SECTION 1401. Collateral and Security Documents.

          From and after the Escrow Release Date, the due and punctual payment of the principal of and
interest on the Notes when and as the same shall be due and payable, whether on an Interest Payment
Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the
overdue principal of and interest on the Notes and performance of all other obligations of the
Issuer and the Subsidiary Guarantors to the Holders, the Trustee or the Collateral Agent under this
Indenture, the Notes and the Security Documents and Other Pari Passu Lien Obligations, according to
the terms hereunder or thereunder, shall be secured as provided in the Security Documents, which
define the terms of the Liens that secure the obligations. Each of the Trustee and the Issuer
hereby acknowledges and agrees that the Existing Secured Notes Collateral Agent shall hold the
Collateral in trust for the benefit of the Secured Parties, in each case pursuant to the terms of
the Security Documents. Each Holder, by accepting a Note, consents and agrees to the terms of the
Security Documents (including the provisions providing for the possession, use, release and
foreclosure of Collateral) as the same may be in effect or may be amended from time to time in
accordance with their terms and this Indenture, and authorizes and directs the Collateral Agent to
enter into the Security Agreement by the execution and delivery of the Consent Agreement and to
perform its obligations as an Authorized Representative and exercises its rights thereunder in
accordance therewith or in accordance with Section 1410(b) and to appoint the Existing Secured
Notes Collateral Agent as agent on its behalf and on behalf of all other Secured Parties and to
exercise such powers under the Security Agreement as are delegated to the Existing Secured Notes
Collateral Agent by the terms thereof; provided, however, that if any of the provisions of the
Security Documents limit, qualify or conflict with the duties imposed by the provisions of the TIA,
the TIA shall control. The Issuer shall deliver to the Collateral Agent copies of all documents
pursuant to the Security Documents, and will do or cause to be done all such acts and things as may
be reasonably required by the next sentence of this Section 1401, to assure and confirm to the
Collateral Agent the security interest in the Collateral contemplated hereby, by the Security
Documents or any part thereof, as from time to time constituted, so as to render the same available
for the security and benefit of this Indenture and of the Notes secured hereby, according to the
intent and purposes herein expressed. The Issuer shall, and shall cause the Subsidiaries of the
Issuer to, use its commercially reasonable efforts to take any and all actions reasonably required
to cause the Security Documents to create and maintain, as security for the Obligations and Other
Pari Passu Lien Obligations, a valid and enforceable perfected (to the extent required by the
Security Documents) Lien and security interest in and on all of the Collateral, in favor of the
Existing Secured Notes Collateral Agent for the benefit of the Secured Parties. The Issuer shall,
and shall cause the Subsidiary Guarantors of the Issuer to, and each Subsidiary Guarantor shall,
make all filings (including filings of continuation statements and amendments to financing
statements that may be necessary to continue the effectiveness of such financing statements) and
take all other actions as are necessary or required by the Security Documents to maintain (at the
sole cost and expense of the Issuer and the Subsidiary Guarantors) the security interest created by
the Security Documents in the Collateral (other than with respect to any Collateral the security
interest in which is not required to be perfected under the Security Documents) as a perfected
security interest and subject only to Permitted Liens.

-116-

 

          SECTION 1402. Recordings and Opinions.

          (a) To the extent applicable, the Issuer will cause TIA § 313(b), relating to reports, to be
complied with. The Issuer shall not be required to comply with TIA § 314.

          (b) Any release of Collateral permitted by Section 1403 hereof will be deemed not to impair
the Liens under this Indenture, the Security Agreement and the other Security Documents in
contravention thereof.

          SECTION 1403. Release of Collateral.

          On the Escrow Release Date, the Escrow Issuer shall be released from all of its obligations
and the Liens on the Escrow Account and the Escrow Collateral shall be released. From and after the
Escrow Release Date, subject to Sections 1402(b) and 1404 hereof, the Liens on the Collateral securing the Notes
will automatically and without the need for any further action by any Person be released:

     (1) in whole or in part, as applicable, as to all or any portion of property subject to
such Liens which has been taken by eminent domain, condemnation or other similar
circumstances;

     (2) in whole upon:

     (A) satisfaction and discharge of this Indenture as set forth below under
Article Four; or

     (B) a legal defeasance or covenant defeasance of this Indenture as described
above under Article Thirteen;

     (3) in part, as to any property that (a) is sold, transferred or otherwise disposed of
by the Issuer or any Subsidiary Guarantor (other than to the Issuer or another Subsidiary
Guarantor) in a transaction not prohibited by this Indenture at the time of such sale,
transfer or disposition or (b) is owned or at any time acquired by a Subsidiary Guarantor
that has been released from its Subsidiary Guarantee in accordance with this Indenture,
concurrently with the release of such Subsidiary Guarantee in each case as certified by an
Officer’s Certificate;

     (4) in part, as to any Collateral of a Restricted Subsidiary that is designated as an
Unrestricted Subsidiary in a transaction or other circumstance that complies with the
provisions of this Indenture and other relevant provisions of any other Secured Debt
Documents, at the time such Restricted Subsidiary is designated as an Unrestricted
Subsidiary; and

     (5) in part, in accordance with the applicable provisions of the Security Documents.

          SECTION 1404. [INTENTIONALLY DELETED]

          SECTION 1405. Suits to Protect the Collateral.

          Subject to the provisions of Article Six hereof and the Security Documents, the Trustee, in
its capacity as Collateral Agent, in its sole discretion and without the consent of the Holders, on
behalf of the Holders, may, and upon direction of a majority of Holders shall, direct the Existing
Secured Notes Collateral Agent to take all actions it deems necessary or appropriate in order to:

          (a) enforce any of the terms of the Security Documents; and

          (b) collect and receive any and all amounts payable in respect of the obligations
hereunder.

-117-

 

          Subject to the provisions of the Security Documents, the Trustee shall have power to institute
and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of
the Collateral by any acts which may be unlawful or in violation of any of the Security Documents
or this Indenture, and such suits and proceedings as the Trustee, in its sole discretion, may deem
expedient to preserve or protect its interests and the interests of the Holders in the Collateral
(including power to institute and maintain suits or proceedings to restrain the enforcement of or
compliance with any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the Lien on the Collateral or be prejudicial to the interests of the
Holders or the Trustee). Nothing in this Section 1405 shall be considered to impose any such duty
or obligation to act on the part of the Trustee. For the avoidance of doubt, neither the Trustee
nor the Collateral Agent will be authorized or permitted to direct the Existing Secured Notes
Collateral Agent under the Security Agreement unless it is also the Applicable Authorized
Representative.

          SECTION 1406. Authorization of Receipt of Funds by the Trustee Under the Security
Documents.

          Subject to the provisions of an Intercreditor Agreement, the Trustee is authorized to receive
any funds for the benefit of the Holders distributed under the Security Documents, and to make
further distributions of such funds to the Holders according to the provisions of this Indenture.

          SECTION 1407. Purchase Protected.

          In no event shall any purchaser in good faith of any property purported to be released
hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the
release or to inquire as to the satisfaction of any conditions required by the provisions hereof
for the exercise of such authority or to see to the application of any consideration given by such
purchaser or other transferee; nor shall any purchaser or other transferee of any property or
rights permitted by this Article Fourteen to be sold be under any obligation to ascertain or
inquire into the authority of the Issuer or the applicable Subsidiary Guarantor to make any such
sale or other transfer.

          SECTION 1408. Powers Exercisable by Receiver or Trustee.

          In case the Collateral shall be in the possession of a receiver or trustee, lawfully
appointed, the powers conferred in this Article Fourteen upon the Issuer or a Subsidiary Guarantor
with respect to the release, sale or other disposition of such property may be exercised by such
receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the
equivalent of any similar instrument of the Issuer or a Subsidiary Guarantor or of any officer or
officers thereof required by the provisions of this Article Fourteen; and if the Trustee shall be
in the possession of the Collateral under any provision of this Indenture, then such powers may be
exercised by the Trustee.

          SECTION 1409. Release upon Termination of the Issuer’s Obligations.

          In the event that the Issuer delivers to the Trustee, in form and substance reasonably
acceptable to it, an Officers’ Certificate certifying that (i) payment in full of the principal of,
together with accrued and unpaid interest (including additional interest, if any) on, the Notes and
all other Obligations under this Indenture, the Guarantees and the Security Documents that are due
and payable at or prior to the time such principal, together with accrued and unpaid interest, are
paid or (ii) the Issuer shall have exercised its Legal Defeasance option or its Covenant Defeasance
option, in each case in compliance with the provisions of Article Thirteen, the Trustee shall
deliver to the Issuer and the Collateral Agent a notice stating that the Trustee, on behalf of the
Holders, disclaims and gives up any and all rights it has in or to the Collateral (other than with
respect to funds held by the Trustee pursuant to Article Thirteen), and any rights it has under the
Security Documents, and upon receipt by the Collateral Agent of such notice, the Collateral Agent
shall be deemed not to hold a Lien in the Collateral on behalf of the Trustee and shall do or cause
to be done all acts reasonably necessary to release such Lien as soon as is reasonably practicable.

          SECTION 1410. Collateral Agent.

          (a) The Trustee and each of the Holders by acceptance of the Notes hereby designates and
appoints the Collateral Agent as its agent under this Indenture, the Security Agreement and the
Security Documents and the Trustee and each of the Holders by acceptance of the Notes hereby
irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions
of this Indenture, the Security Agreement and the Security Documents and to exercise such powers
and perform such duties as are expressly delegated to the Collateral Agent by the terms of this
Indenture, the Security Agreement and the Security Documents, together with such powers as are
reasonably incidental thereto including the exercise of any rights as an Authorized Representative,
if any, under the Security Agreement. The Collateral Agent agrees to act as such on the express
conditions contained in this Section 1410. The provisions of this Section 1410 are solely for the
benefit of the Collateral Agent and none of the Trustee, any of the Holders nor the Issuer or any
of the Subsidiary Guarantors shall have any rights as a third party beneficiary of any of the
provisions contained herein other than as expressly provided in Section 1403. Notwithstanding
any provision to the contrary contained elsewhere in this Indenture, the Security Agreement
and the Security Documents, the Collateral Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall the Collateral Agent have or be deemed to have
any fiduciary relationship with the Trustee, any Holder or the Issuer or any Subsidiary Guarantor,
and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be
read into this Indenture, the Security Agreement and the Security Documents or otherwise exist
against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use
of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under agency doctrine of
any applicable law. Instead, such term is used merely as a matter of market custom, and is
intended to create or reflect only an administrative relationship between independent contracting
parties. Except as expressly otherwise provided in this Indenture, the Collateral Agent shall have
and may use its sole discretion with respect to exercising or refraining from exercising any
discretionary rights or taking or refraining from taking any actions which the Collateral Agent is
expressly entitled to take or assert under this Indenture, the Security Agreement and the Security
Documents, including the exercise of remedies pursuant to Article Five, and any action so taken or
not taken shall be deemed consented to by the Trustee and the Holders.

          (b) The Collateral Agent may execute any of its duties under this Indenture or the Security
Documents by or through agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be
responsible for the negligence or misconduct of any agent, employee or attorney-in-fact that it
selects as long as such selection was made with due care.

          (c) None of the Collateral Agent or any of its agents or employees shall (i) be liable for any
action taken or omitted to be taken by any of them under or in connection with this Indenture or
the transactions contemplated hereby (except for its own gross negligence or willful misconduct) or
under or in connection with the Security Agreement or any Security Document or the transactions
contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be
responsible in any manner to the Trustee or any Holder or any other Person for any recital,
statement, representation, warranty, covenant or agreement made by the Issuer or any Subsidiary
Guarantor, contained in this or any Indenture, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Collateral Agent under or in connection
with, this or any other Indenture, the Security Agreement or the Security Documents, or the
validity, effectiveness, genuineness, enforceability or sufficiency of this or any other Indenture,
the Security Agreement or the Security Documents, or for any failure of the Issuer or any
Subsidiary Guarantor or any other party to this Indenture, the Security Agreement or the Security
Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any
of its agents or employees shall be under any obligation to the Trustee or any Holder or any other
Person to ascertain or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this or any other Indenture, the Security Agreement or the Security
Documents or to inspect the properties, books or records of the Issuer or any Subsidiary Guarantor.

          (d) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying,
upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile,
telex or telephone message,

-119-

 

statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon
advice and statements of legal counsel (including, without limitation, counsel to the Issuer or any
Subsidiary Guarantor), independent accountants and other experts and advisors selected by the
Collateral Agent. The Collateral Agent shall be fully justified in failing or refusing to take any
action under this Indenture or any other indenture or the Security Documents unless it shall first
receive such advice or concurrence of the Trustee as it deems appropriate and, if it so requests,
it shall first be indemnified to its satisfaction by the Holders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take any such action. The
Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting,
under this Indenture or any other indenture or the Security Documents in accordance with a request
or consent of the Trustee and such request and any action taken or failure to act pursuant thereto
shall be binding upon all of the Holders or any other Person.

          (e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of
any Default or Event of Default, unless the Collateral Agent shall have received written notice
from the Trustee or the Issuer referring to this Indenture, describing such Default or Event of Default and
stating that such notice is a “notice of default.” The Collateral Agent shall take such action
with respect to such Default or Event of Default as may be requested by the Trustee in accordance
with Article Five (subject to Section 1410); provided, however, that unless and until the
Collateral Agent has received any such request, the Collateral Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable.

          (f) Wilmington Trust FSB and its Affiliates (and any successor Collateral Agent and its
Affiliates) may make loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust, financial advisory,
underwriting, or other business with the Issuer and the Subsidiary Guarantors as though it was not
the Collateral Agent hereunder and without notice to or consent of the Trustee. The Trustee and
the Holders acknowledge that, pursuant to such activities, Wilmington Trust FSB or its Affiliates
(and any successor Collateral Agent and its Affiliates) may receive information regarding the
Issuer and the Subsidiary Guarantors (including information that may be subject to confidentiality
obligations in favor of the Issuer and the Subsidiary Guarantors) and acknowledge that the
Collateral Agent shall not be under any obligation to provide such information to the Trustee or
the Holders. Nothing herein shall impose or imply any obligation on the part of Wilmington Trust
FSB (or any successor Collateral Agent) to advance funds.

          (g) The Collateral Agent may resign at any time upon thirty (30) days prior written notice to
the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor
agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this
Indenture, the Issuer (or, during a continuing Event of Default, the Trustee at the direction of
the majority of the Holders), shall appoint a successor Collateral Agent. If no successor
collateral agent is appointed prior to the intended effective date of the resignation of the
Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after
consulting with the Trustee acting at the direction of the majority of the Holders, subject to the
consent of the Issuer (which shall not be unreasonably withheld and which shall not be required
during a continuing Event of Default), a successor collateral agent. If no successor collateral
agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty
(30) days after the intended effective date of resignation (as stated in the notice of resignation)
the Collateral Agent shall be entitled to petition at the expense of the Issuer a court of
competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor
collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers
and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such
successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as
the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation
hereunder, the provisions of this Section 1410 (and Section 1411) shall continue to inure to its
benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be
released from liability as to any actions taken or omitted to be taken by it while it was the
Collateral Agent under this Indenture.

          (h) The Trustee shall initially act as Collateral Agent and shall be authorized to appoint
co-Collateral Agents as necessary in its sole discretion. Except as otherwise explicitly provided
herein or in the

-120-

 

Security Documents, neither the Collateral Agent nor any of its officers,
directors, employees or agents shall be liable for failure to demand, collect or realize upon any
of the Collateral or for any delay in doing so or shall be under any obligation to sell or
otherwise dispose of any Collateral upon the request of any other Person or to take any other
action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be
accountable only for amounts that it actually receives as a result of the exercise of such powers,
and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be
responsible for any act or failure to act hereunder, except for its own willful misconduct, gross
negligence or bad faith.

          (i) The Trustee, as such and as Collateral Agent, is authorized and directed to (i) enter into
the Security Agreement (through the execution of the Consent Agreement by the Authorized
Representative of the Collateral Agent) and the Security Documents, (ii) enter into an
Intercreditor Agreement, (iii) bind the Holders on the terms as set forth in the Security
Agreement, and the Security Documents and the Intercreditor Agreement and (iv) perform and observe
its obligations under the Security Agreement and the Security Documents and the Intercreditor
Agreement.

          (j) The Trustee agrees that it shall not (and shall not be obliged to), and shall not instruct
the Collateral Agent to, unless specifically requested to do so by a majority of the Holders, take
or cause to be taken any action to enforce its rights under this Indenture or against the Issuer
and the Subsidiary Guarantors, including the commencement of any legal or equitable proceedings, to
foreclose any Lien on, or otherwise enforce any security interest in, any of the Collateral.

          If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or
otherwise, any proceeds of Collateral or any payments with respect to the Obligations arising
under, or relating to, this Indenture, except for any such proceeds or payments received by the
Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from
the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article
Five, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such
endorsements as may be required to negotiate the same to the Collateral Agent.

          (k) Should the Trustee obtain possession of any such Collateral, upon request from the Issuer,
the Trustee shall notify the Collateral Agent thereof, and, promptly upon the Collateral Agent’s
request therefor, shall deliver such Collateral to the Collateral Agent or otherwise deal with such
Collateral in accordance with the Collateral Agent’s instructions.

          (l) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the
Holders or any other Person to assure that the Collateral exists or is owned by the Issuer and the
Subsidiary Guarantors or is cared for, protected or insured or has been encumbered, or that the
Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected,
protected, maintained or enforced or are entitled to any particular priority, or to determine
whether all of the grantor’s property constituting collateral intended to be subject to the Lien
and security interest of the Security Documents has been properly and completely listed or
delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof
or title thereto, or to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers
granted or available to the Collateral Agent pursuant to this Indenture or any Security Document,
it being understood and agreed that in respect of the Collateral, or any act, omission or event
related thereto, the Collateral Agent may act in any manner it may deem appropriate, in its sole
discretion given the Collateral Agent’s own interest in the Collateral, and that the Collateral
Agent shall have no other duty or liability whatsoever to the Trustee or any Holder or any other
Person as to any of the foregoing.

          (m) No provision of this Indenture, the Security Agreement or any Security Document shall
require the Collateral Agent (or the Trustee) to expend or risk its own funds or otherwise incur
any financial liability in the performance of any of its duties hereunder or thereunder or to take
or omit to take any action hereunder or thereunder or take any action at the request or direction
of Holders (or the Trustee in the case of the Collateral Agent) if it shall have reasonable grounds
for believing that repayment of such funds is not assured to it.

-121-

 

          (n) The Collateral Agent (i) shall not be liable for any action it takes or omits to take in
good faith which it reasonably believes to be authorized or within its rights or powers, or for any
error of judgment made in good faith by a Responsible Officer, unless it is proved that the
Collateral Agent was grossly negligent in ascertaining the pertinent facts, (ii) shall not be
liable for interest on any money received by it except as the Collateral Agent may agree in writing
with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other
funds except to the extent required by law), and (iii) may consult with counsel of its selection
and the advice or opinion of such counsel as to matters of law shall be full and complete
authorization and protection from liability in respect of any action taken, omitted or suffered by
it in good faith and in accordance with the advice or opinion of such counsel. The grant of
permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

          (o) Notwithstanding anything to the contrary herein, the obligations of the Issuer and
Subsidiary Guarantors owing to the Collateral Agent shall remain in full force and effect and all
of the Collateral Agent’s rights, protections, indemnities and immunities granted hereunder shall
survive the satisfaction and discharge of this Indenture so long as the Security Agreement to which the Collateral Agent is a
party remains effective and outstanding.

          (p) Notwithstanding anything to the contrary, the Collateral Agent’s sole responsibility is to
execute and deliver the Consent Agreement, to act as an Authorized Representative under the
Security Agreement and to exercise such rights and powers if it becomes the Applicable Authorized
Representative under the Security Agreement in directing the Existing Secured Notes Collateral
Agent in accordance with the Security Documents in each case at the direction of the Trustee and/or
Holders in accordance with the terms of this Indenture.

          SECTION 1411. Compensation and Indemnification.

          The Collateral Agent shall be entitled to the compensation, reimbursement of expenses,
disbursements and advances, and indemnification set forth in Section 607 (with the references to
the Trustee therein being deemed to refer to the Collateral Agent).

          SECTION 1412. Security Agreement and Other Security Documents.

          Upon the consummation of the Assumption, the Collateral Agent is hereby directed and
authorized to execute and deliver the Consent Agreement; provided that the Collateral Agent may
request and be fully protected in relying upon an Officers’ Certificate certifying that each of
clauses (i) and (ii) of the Consent Agreement are true and correct as of the date hereof. It is
hereby expressly acknowledged and agreed that, in doing so, the Trustee and the Collateral Agent
are not responsible for the terms or contents of such agreements, or for the validity or
enforceability thereof, or the sufficiency thereof for any purpose. Whether or not so expressly
stated therein, in entering into, or taking (or forbearing from) any action under or pursuant to
the Security Agreement, any other Security Documents or any Intercreditor Agreement, the Trustee
and Collateral Agent each shall have all of the rights, immunities, indemnities and other
protections granted to it under this Indenture (in addition to those that may be granted to it
under the terms of such other agreement or agreements).

[REVERSE SIDE OF NOTE]

CLEARWIRE ESCROW CORPORATION

12% Senior Secured Note due 2015

1. Principal and Interest; Subordination.

          Prior to the consummation of the Assumption (as defined in the Indenture), the references in
this Note to the “Issuer” refers to Clearwire Escrow Corporation, a Delaware corporation. After
the consummation of the Assumption, the references in this Note to the “Issuer” refers only to
Clearwire Communications LLC (the “Company”) and Clearwire Finance, Inc. (“Finance Co”).

          The Issuer will pay the principal of this Note on December 1, 2015.

          The Issuer promises to pay interest on the principal amount of this Note on each Interest
Payment Date, as set forth below, at the rate of 12% per annum (subject to adjustment as provided
below).

          Interest will be payable semi-annually (to the Holders of record of the Notes (or any
Predecessor Notes)) at the close of business on June 1 or December 1 immediately preceding the
Interest Payment Date) on each Interest Payment Date, commencing June 1, 2010.

          Interest on this Note will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from June 1, 2010; provided that, if there is no existing default
in the payment of interest and if this Note is authenticated between a Regular Record Date referred
to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve
30-day months.

          The Issuer shall pay interest on overdue principal and premium, if any, and interest on
overdue installments of interest, to the extent lawful, at a rate per annum equal to the rate of
interest applicable to the Notes.

2. Method of Payment.

          The Issuer will pay interest (except defaulted interest) on the principal amount of the Notes
on each June 1 and December 1 to the Persons who are Holders (as reflected in the Note Register at
the close of business on May 15 and June 15 immediately preceding the Interest Payment Date), in
each case, even if the Note is cancelled on registration of transfer or registration of exchange
after such Regular Record Date; provided that, with respect to the payment of principal, the Issuer
will make payment to the Holder that surrenders this Note to any Paying Agent on or after December
1, 2015.

          The Issuer will pay principal (premium, if any) and interest in money of the United States
that at the time of payment is legal tender for payment of public and private debts. However, the
Issuer may pay principal (premium, if any) and interest by its check payable in such money. The
Issuer may pay interest on the Notes either (a) by mailing a check for such interest to a Holder’s
registered address (as reflected in the Note Register) or (b) by wire transfer to an account
located in the United States maintained by the payee. If a payment date is a date other than a
Business Day at a place of payment, payment may be made at that place on the next succeeding day
that is a Business Day and no interest shall accrue for the intervening period.

A-4

 

3. Paying Agent and Note Registrar.

          Initially, the Trustee will act as Paying Agent and Note Registrar. The Issuer may change any
Paying Agent or Note Registrar upon written notice thereto. The Issuer, any Subsidiary or any
Affiliate of any of them may act as Paying Agent, Note Registrar or co-registrar.

4. Indenture; Limitations.

          The Issuer issued the Notes under an Indenture dated as of December 9, 2009 (the “Indenture”),
among the Issuer, the Subsidiary Guarantors and Wilmington Trust FSB, as trustee (the “Trustee”)
and collateral agent (the “Collateral Agent”). Capitalized terms herein are used as defined in the
Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are
subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act
for a statement of all such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the terms of the
Indenture shall control.

          The Notes are senior secured obligations of the Issuer. The Indenture does not limit the
aggregate principal amount of the Notes.

5. Redemption.

          Optional Redemption. Except as described below, the Notes are not redeemable at the
Issuer’s option until December 1, 2012. From and after December 1, 2012, the Issuer may redeem the
Notes, in whole or in part, upon not less than 30 nor more than 60 days’ prior notice by first
class mail, postage prepaid, with a copy to the Trustee, to each Holder of Notes to the address of
such Holder appearing in the Note Register at the Redemption Prices (expressed as percentages of
principal amount) set forth below, plus accrued and unpaid interest thereon, if any, to but
excluding the applicable redemption date, subject to the right of Holders of record on the relevant
Record Date to receive interest due on the relevant Interest Payment Date, if redeemed during the
twelve-month period beginning on December 1 of each of the years indicated below:

	 	 	 	 	 
	Year	 	Percentage	 
	2012
	 	 	106.000	%
	2013
	 	 	103.000	%
	2014 and thereafter
	 	 	100.000	%

          In addition, prior to December 1, 2012, the Issuer may, at its option, redeem up to 35% of the
aggregate principal amount of Notes issued under the Indenture at a redemption price equal to
112.000% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if

     THIS ESCROW AND SECURITY AGREEMENT is entered into on December 9, 2009 (as amended, modified
or supplemented from time to time in accordance with the Indenture described below, this
“Agreement”), by and between, Wilmington Trust FSB in its capacities as escrow agent,
depositary bank and securities intermediary (collectively in such capacities, the “Escrow
Agent”), and in its capacity as trustee under the Indenture described below (in such capacity,
the “Trustee”), Clearwire Escrow Corporation, a Delaware corporation (the
“Grantor”), and Clearwire Communications LLC, a Delaware limited liability company (the
“Company”), solely with respect to Sections 1.1(c), 1.7(d) and 3.2 of this Agreement.

RECITALS

     Pursuant to that certain indenture (as amended, supplemented or modified from time to time,
the “Indenture”) dated as of December 9, 2009, by and among the Grantor and the Trustee,
the Grantor will issue $920,000,000 in aggregate principal amount of its 12% Senior Secured Notes
due 2015 (the “Notes”). The Notes are being issued in a private placement (the
“Offering”) pursuant to that certain purchase agreement dated as of November 24, 2009 (the
“Purchase Agreement”), by and among the Grantor, the Company, Clearwire Finance, Inc.
(“Finance Co”), the Subsidiaries of the Company party thereto (the “Future Subsidiary
Guarantors”) and J.P. Morgan Securities Inc. (the “Initial Purchaser”). In accordance
with Section 3.3(e) hereof, capitalized terms that are used but not defined herein have the
meanings assigned to them in the Indenture.

     WHEREAS, concurrently with the closing of the sale of the Notes, the Initial Purchaser, on
behalf of the Grantor, will deposit into the Escrow Account (as defined below), as hereinafter
provided, the gross proceeds from the Offering;

     WHEREAS upon satisfaction of the Escrow Conditions (as defined below), the Company and Finance
Co will become obligated to assume the rights and obligations under all of the Notes and the
Indenture, as the successor obligors under the Notes, on the Escrow Release Date (as defined in the
Indenture). If the Escrow Conditions are not satisfied, the Company and Finance Co will become
obligated to assume the rights and obligations under $540.0 million aggregate principal amount (the
“Automatic Assumption Amount”) of the Notes and the Indenture, as the successor obligors
under such Notes and consummate the redemption described in Section 1109 of the Indenture, in each
case, on the Escrow Release Date. Each of the aforementioned assumptions of rights and obligations
by the Company and Finance Co is referred to as the “Assumption”. The Assumption will be effected
by the execution and delivery of a supplemental indenture by the Grantor, the Company, Finance Co
and the Future Subsidiary Guarantors pursuant to which the Company and Finance Co will become party
to the Indenture and assume all obligations of the Grantor therein and under all of the Notes or
the Automatic Assumption Amount of the Notes, as applicable (the “Assumed Notes”), and the
Future Subsidiary Guarantors will become party to the Indenture and guarantee all obligations of
Company and Finance Co under the Assumed Notes (the “Guarantees”). In connection with the
Assumption, (i) the Company shall designate the Assumed Notes and Guarantees as “Other Pari Passu
Lien Obligations” in accordance with Section 7.19 of the collateral agreement (the “Security
Agreement”) dated November 24, 2009, among the Company, Finance Co, the Future Subsidiary
Guarantors and Wilmington Trust FSB, as collateral agent for the benefit of itself, holders of 12%
Senior Secured Notes due 2015 issued by the Company and Finance Co (the “Existing Secured
Notes”) and the trustee under the indenture governing the Existing Secured Notes and (ii) the
Collateral Agent shall execute a consent agreement whereby it shall become party to the Security
Agreement and the other Security Documents for its benefit, the benefit of the Trustee and Holders
of the Assumed Notes and the Guarantees and the Assumed Notes will be secured on a first priority
basis, subject to certain Permitted Liens (as defined in the Indenture), by liens on the Collateral
(as defined in the Security Agreement).

 

 

     WHEREAS, the “Escrow Release Date” will be the earliest to occur of (x) the consummation of
the Second Investment Closing (as defined in the Offering Memorandum), (y) the date on which the
Grantor determines in its sole discretion that the Second Investment Closing cannot occur and (z)
June 9, 2010. Whereas, on the Escrow Release Date, (i) if the Escrow Conditions are satisfied, the
Assumption and related steps described above will occur with respect to all of the Notes and (ii)
if the Escrow Conditions are not satisfied, (a) the Assumption and related steps described above
will occur with respect to solely the Automatic Assumption Amount of Notes and (b) the Grantor will
redeem $380,000,000 aggregate principal amount of Notes at a redemption price equal to
$372,191,000, plus interest accrued on $372,191,000 from the date hereof to, but excluding, the
Escrow Release Date, calculated using a rate of 12.5% per annum, in accordance with the terms of
Section 1109 of the Indenture (the “Escrow Redemption Price”).

     WHEREAS,
as security for its obligations under the Notes and the Indenture,
the Grantor desires to grant  to the Trustee, for the benefit of the holders of the Notes, a first priority security
interest in and lien upon the Escrow Collateral (as defined herein) on the terms and conditions set
forth herein; and

     WHEREAS, the parties have entered into this Agreement in order to set forth the conditions
upon which, and the manner in which, funds will be held in and disbursed from the Escrow Account
(as defined herein) and released from the security interest and lien described above.

     The Grantor, the Trustee and the Escrow Agent hereby agree that, in consideration of the
mutual promises and covenants contained herein, the Escrow Agent will hold in escrow and will
distribute Escrow Property in accordance with and subject to the following:

1. INSTRUCTIONS

1.1. Escrow Property.

       The funds to be deposited with the Escrow Agent will be as follows:

	(a)	 	Concurrently with the execution and delivery hereof and the issuance of the Notes, as
provided in the Purchase Agreement, the Initial Purchaser will deposit with the Escrow Agent

which amount represents the gross proceeds from the Offering (which is net of “original issue
discount” in connection with the offering of the Notes, but includes a deferred discount of
$16,100,000 (the “Deferred Discount”) payable to the Initial Purchaser on the Release
Date).
	 
	(b)	 	The Escrow Agent will accept the Initial Deposit and will hold such funds, all investments
thereof, any Distributions (as hereinafter defined) and the proceeds of the foregoing in a
Securities Account created by the Escrow Agent prior to or concurrently with the issuance of
the Notes. Such Securities Account will have account number 095173-001 and shall be
maintained by the Escrow Agent in the name of the Trustee (such account, together with any
other account maintained by the Escrow Agent hereunder, the “Escrow Account”) for
disbursement in accordance with the provisions hereof. The Trustee will be the entitlement
holder and customer of the Escrow Agent with respect to the Escrow Account. The Grantor will
not have any access to the Escrow Account or funds, investments or other assets credited
thereto, other than the limited contractual right to receive the Escrow Property under the
circumstances specified in Section 1.4 hereof. The Initial Deposit, the Escrow Account and all
funds, securities or other property now or hereafter credited to the Escrow Account, all
investments of any of the

-2-

 

	 	 	foregoing, plus all interest, dividends and other distributions and payments on any of the
foregoing (collectively the “Distributions”) received or receivable by the Escrow
Agent, less any property and/or funds distributed or paid in accordance with this Agreement,
together with all proceeds of any of the foregoing are collectively referred to herein as
“Escrow Property.”
	 
	(c)	 	If the Escrow Property is to be released pursuant to Section 1.4(d) and the aggregate amount
of Escrow Property is not sufficient to satisfy all amounts payable under clauses (i) through
(iv) thereof, then the Company shall deposit with the Trustee the amount required to satisfy
(together with the Escrow Property) all amounts payable under such clauses.

1.2. Grantor’s Limited Rights in Escrow Property; Security Interest.

	(a)	 	It is the intention of the parties hereto that this Agreement create a true escrow, and the
Grantor have no ownership of, or rights in, the Escrow Account or the Escrow Property other
than the limited contractual right to receive the Escrow Property under the circumstances
specified in Section 1.4 hereof.
	 
	(b)	 	If, notwithstanding the intention of the parties set forth in
Section 1.2(a) hereof, the Grantor is determined  to have any
interest in any Escrow Property, as security for the due and punctual payment when due of all amounts that may be payable from
time to time under the Indenture and the Notes, now or hereafter arising, the Grantor hereby
pledges and grants to the Trustee, for the benefit of the Secured Parties, a continuing first
priority (subject to liens of  the Escrow Agent) security interest in all of the Grantor’s
right, title and interest, to and under the following whether now or hereafter existing or
acquired (collectively, the “Escrow Collateral”): (i) the Escrow Account, and all
Financial Assets and other property from time to time placed or deposited in, or delivered to
the Escrow Agent for placement or deposit in the Escrow Account, including, without
limitation, all Escrow Property; (ii) all Security Entitlements from time to time credited to
the Escrow Account; (iii) all claims and rights of whatever nature which the Grantor may now
have or hereafter acquire against any third party(ies) in respect of any of the Escrow
Collateral described in this Section 1.2 (including any claims or rights in respect of any
Security Entitlements credited to an account of the Escrow Agent maintained at The Depository
Trust Company or any other clearing corporation) or any other Securities Intermediary; (iv)
all rights which the Grantor may now have or hereafter acquire against the Escrow Agent in
respect of its holding and managing all or any part of the Escrow Collateral; and (v) all
proceeds (as such term is defined in Section 9-102(a) of the UCC) of any of the foregoing.
The Escrow Agent hereby acknowledges the Trustee’s security interest as set forth in this
Section 1.2. The Grantor shall take all actions and shall direct the Trustee in writing to
take all actions reasonably necessary on its part to ensure (i) the continuance of a security
interest in the Escrow Collateral in favor of the Trustee for its benefit and for the benefit
of the Secured Parties in order to secure all the Obligations under the Indenture and the
Notes and (ii) that such security interest is at all times a perfected first priority (subject
to liens of the Escrow Agent) security interest. The Grantor shall not grant or cause or
permit any other person to obtain a security interest, encumbrance, lien or other claim,
direct or indirect, in the Grantor’s right, title or interest in the Escrow Collateral other
than the Escrow Agent’s lien arising by operation of law and the rights of set-off pursuant to
Section 1.7(d) hereof. The Grantor represents and warrants that the security interest of the
Trustee in the Escrow Collateral pursuant to this Agreement and, to the extent that the
Grantor has rights therein, the Escrow Collateral, will, after execution and delivery of this
Agreement by all parties hereto, at all times be valid, perfected and enforceable (subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors’ rights generally and subject to general principles of equity, regardless of whether
considered in a proceeding in equity or at law) as a first priority
(subject to liens of the Escrow Agent) security interest by the
Trustee against the Grantor and all third parties in accordance with the terms of this
Agreement.

-3-

 

	(c)	 	The parties hereto acknowledge and agree that: (i) the Escrow Account will be treated as a
“Securities Account,” (ii) the Escrow Property will be treated as “Financial Assets,” (iii)
this Agreement governs the Escrow Account and provides rules governing the priority among
possible “Entitlement Orders” received by the Escrow Agent as “Securities Intermediary” from
the Grantor, the Trustee and any other persons entitled to give “Entitlement Orders” with
respect to such Financial Assets and (iv) the “Securities Intermediary’s Jurisdiction” is the
State of New York. The Escrow Agent represents and warrants that the Escrow Agent is a
“Securities Intermediary” with respect to the Escrow Account and the “Financial Assets”
credited to the Escrow Account. Except as specifically provided herein, the terms of the UCC,
will apply to this Agreement, and all terms quoted in this clause (c) and clause (e) will have
the meanings assigned to them by Article 8 of the UCC.
	 
	(d)	 	The Escrow Agent hereby agrees that all property delivered to the Escrow Agent for crediting
to the Escrow Account will be promptly credited to the Escrow Account by the Escrow Agent.
The Escrow Agent represents and warrants that it has not entered into, and agrees that it will
not enter into, any control agreement or any other agreement relating to the Escrow Account
with any other third party without the prior written consent of the Grantor, the Trustee and
the Initial Purchaser, except for this Escrow Agreement.
	 
	(e)	 	Each of the parties hereto acknowledge and agree that the Escrow Account will be under the
control (within the meanings of Sections 8-106, 9-106 and 9-104 of the UCC) of the Trustee
and, notwithstanding any other provision of this Agreement, the Escrow Agent will comply with
all “Entitlement Orders” and instructions given by the Trustee with respect to the Escrow
Account or Escrow Property without further consent of the Grantor or any other person. Except
as expressly set forth in Section 1.3 hereof, the Grantor shall have no right to give any
Entitlement Orders or instructions.
	 
	(f)	 	The Grantor agrees to take all steps reasonably necessary to maintain the security interest
created by this Agreement as a perfected first-priority security interest including causing
UCC financing statements describing the Escrow Collateral to be promptly filed in the State of
Delaware. Without limiting the foregoing, the Grantor agrees to take all steps reasonably
requested by the Trustee in connection with the perfection of the Trustee’s security interest
in the Escrow Collateral pursuant to this Agreement and, without limiting the generality of
the foregoing, the Grantor hereby authorizes the Trustee and the Initial Purchaser on behalf
of the Trustee to file one or more UCC financing statements that reasonably describe the
collateral in such jurisdictions and filing offices and containing such description of
collateral as the Trustee, or the Initial Purchaser on behalf of the Trustee, may determine is
reasonably necessary in order to perfect the security interest granted herein; provided, that
the foregoing authorization shall not impose any obligation of the Grantor to maintain the
security interest as provided herein on the Trustee or the Initial Purchaser. The Grantor
represents and warrants that as of the date hereof it is duly formed and validly existing as a
corporation under the laws of the state of Delaware and is not organized under the laws of any
other jurisdiction, and the Grantor hereby agrees that, prior to the termination of this
Agreement, it will not change its name or jurisdiction of organization without giving the
Trustee and the Initial Purchaser not less than 10 days’ prior written notice thereof.
	 
	(g)	 	Upon the release of any Escrow Collateral pursuant to Section 1.4 hereof, the security
interest of the Trustee for the benefit of the Secured Parties will automatically terminate
with respect to any such Escrow Collateral released without any further action and such
released Escrow Collateral will be delivered to the recipient free and clear of any and all
liens, claims or encumbrances of any person, including, without limitation, the Escrow Agent,
the Trustee and the holders of the Notes. The Trustee will take all steps necessary to
terminate any financing statements and will

-4-

 

	 	 	execute such other documents without recourse, representation or warranty of any kind as the
Grantor may reasonably request in writing to evidence or confirm the termination of the
security interest in such released Escrow Collateral.
	 
	(h)	 	Upon the occurrence of an Event of Default under the Indenture and for so long as such Event
of Default continues, the Grantor hereby appoints the Trustee as its attorney-in-fact with
full power of substitution to do any act which the Grantor is obligated hereunder to do, and
the Trustee may, but shall not be required to, exercise such rights as the Grantor might
exercise with respect to the Escrow Collateral and take any action in the Grantor’s name to
protect the Trustee’s security interest and lien granted hereunder. In addition to the rights
provided under this Section 1.2, upon the occurrence of an Event of Default under the
Indenture and for so long as such Event of Default continues, the Trustee may, but shall not
be required to, exercise in respect of the Escrow Collateral, in addition to other rights and
remedies provided for herein or otherwise available to it, all other rights and remedies of
secured parties under the UCC or other applicable law. The Trustee may also upon obtaining
possession of the Escrow Collateral as set forth herein, without notice to the Grantor except
as specified below, sell the Escrow Collateral or any part thereof in one or more parcels at
public or private sale, at any exchange, broker’s board or at any of the Trustee’s offices or
elsewhere, for cash, on credit or for future delivery, and upon such other terms as the
Trustee may deem commercially reasonable. The Grantor agrees that, to the extent notice of
sale shall be required by law, at least ten days’ notice to the Grantor of the time and place
of any public sale or the time after which any private sale is to be made shall constitute
reasonable notification. The Trustee shall not be obligated to make any sale regardless of
notice of sale having been given. The Trustee may adjourn any public or private sale from
time to time by announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.

1.3. Investment of Escrow Property.

	(a)	 	Upon written directions from the Grantor, the Escrow Agent will invest or reinvest the Escrow
Property, without distinction between principal and income, in cash and Cash
Equivalents. The Escrow Agent will credit all such cash and investments to the Escrow Account
and hereby agrees to treat any such investment as a “Financial Asset” within the meaning of
Section 8-102(a)(9) of the UCC.
	 
	(b)	 	The Escrow Agent will have no liability for any investment losses, fees, taxes or other
charges arising from or related to any such investment, reinvestment or liquidation of an
investment other than in accordance with Section 2.1 hereof.

manager or adviser in respect of any selection of investments hereunder. It is understood and

in accordance with Section 1.4 hereof. The Escrow Agent shall have no right to set off

or any obligations owed to the Escrow Agent (or its one legal counsel) hereunder.
	 
	(e)	 	The obligations of the Grantor contained in this Section 1.7 will survive the termination of

2. TERMS AND CONDITIONS

2.1. Rights, Duties and Immunities of Escrow Agent.

	(a)	 	Scope of duties. The duties, responsibilities and obligations of the Escrow Agent
will be limited to those expressly set forth herein and no duties, responsibilities or
obligations will be inferred or implied. The Escrow Agent will not be required to inquire as
to the performance or observation of any obligation, term or condition under any other
agreement or arrangement to which the Grantor is a party, even though reference thereto may be
made herein. The Escrow Agent will not be required to comply with any direction or
instruction (other than those contained herein or delivered in accordance with this Agreement)
from the Grantor or any entity acting on its behalf. The Escrow Agent will not be required
to, and will not, expend or risk any of its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder.
	 
	(b)	 	Limitation on liability. The Escrow Agent will not be liable for any action taken or
omitted or for any loss or injury resulting from its actions or its performance or lack of
performance of its duties hereunder in the absence of gross negligence, willful misconduct or
bad faith. In no event will the Escrow Agent be liable (i) for any consequential, punitive or
special damages, regardless of the form of action and whether or not any such damages were
foreseeable and contemplated, (ii) for the acts or omissions of its nominees, correspondents,
designees, subagents or subcustodians, so long as the same are selected with due care, (iii)
for an amount in excess of the value of the Escrow Property, (iv) for the investment or
reinvestment of any cash held by it hereunder in accordance with the terms hereof, including
without limitation any liability for any delays (not resulting from its gross negligence,
willful misconduct or bad faith) in the investment, reinvestment or liquidation of the Escrow
Property, or any loss of interest or income incident to any such delay or (v) for any release
of Escrow Property, if such release is made in accordance with Section 1.4 or the written
directions of the Grantor, the Initial Purchaser and the Trustee.
	 
	(c)	 	Further limitation on liability. The Escrow Agent will not incur any liability for
not performing any act or fulfilling any duty, obligation or responsibility hereunder by
reason of any occurrence beyond the control of the Escrow Agent (including but not limited to
any act or provision of any present or future law or regulation or governmental authority, any
act of God or war, or the unavailability of the Federal Reserve Bank wire or telex or other
wire or communication facility).
	 
	(d)	 	Right to consult counsel. The Escrow Agent may consult with legal counsel of its own
choosing, at the expense of the Grantor in accordance with Section 1.7 hereof, as to any
matter relating to this Agreement and the advice of such counsel or any opinion of counsel
shall be full and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon.
	 
	(e)	 	Collection. All funds and other property deposited into the Escrow Account or
otherwise collected for deposit therein will be subject to the Escrow Agent’s usual collection
practices or terms regarding items received by the Escrow Agent for deposit or collection.
The Escrow Agent will not be required, or have any duty, to notify any Person of any payment
or maturity under the terms of any instrument deposited hereunder, or to take any legal action
to enforce payment of

-10-

 

	 	 	any check, note or security deposited hereunder or to exercise any right or privilege that
may be afforded to the holder of any such security.
	 
	(f)	 	Statements. The Escrow Agent will make available to the Grantor, the Trustee and the
Initial Purchaser monthly statements identifying transactions, transfers or holdings of Escrow
Property, and each such statement will be deemed to be correct and final upon receipt thereof
by the Grantor unless the Escrow Agent is notified in writing to the contrary within 45
Business Days of the date of such statement.
	 
	(g)	 	Disclaimer with respect to Escrow Property. The Escrow Agent will not be responsible
in any respect for the form, execution, validity, value or genuineness of documents or
securities deposited into escrow or held hereunder, or for any description therein, or for the
identity, authority or rights of persons executing or delivering or purporting to execute or
deliver any such document, security or endorsement. The Escrow Agent makes no representation
as to the validity, value, genuineness or the collectability of any security or other document
or instrument held by or delivered to it. The Escrow Agent will not be called upon to advise
any party as to the wisdom in selling or retaining or taking or refraining from any action
with respect to any securities or other property deposited hereunder.
	 
	(h)	 	Ambiguity or uncertainty. In the event of any ambiguity or uncertainty hereunder or
in any notice, instruction or other communication received by the Escrow Agent hereunder, the
Escrow Agent may, in its sole discretion, refrain from taking any action other than retaining
possession of the Escrow Property, unless the Escrow Agent receives written instructions,
signed by each of the Grantor, the Trustee and the Initial Purchaser which eliminates such
ambiguity or uncertainty.
	 
	(i)	 	Conflicting claims. In the event of any dispute between or conflicting claims by or
among the Grantor and/or any other person or entity with respect to any Escrow Property, the
Escrow Agent will be entitled, in its sole discretion, to refuse to comply with any and all
claims, demands or instructions with respect to such Escrow Property so long as such dispute
or conflict continues, and the Escrow Agent will not be or become liable in any way to the
Grantor for failure or refusal to comply with such conflicting claims, demands or
instructions. The Escrow Agent will be entitled to refuse to act until, in its sole
discretion, either (i) such conflicting or adverse claims or demands have been determined by a
final order, judgment or decree of a court of competent jurisdiction, which order, judgment or
decree is not subject to appeal, or settled by agreement between the conflicting parties as
evidenced in a writing satisfactory to the Escrow Agent or (ii) the Escrow Agent has received
security or an indemnity satisfactory to it sufficient to hold it harmless from and against
any and all Losses (as defined in Section 2.2 hereof) which it may incur by reason of so
acting. The Escrow Agent may, in addition, elect, in its sole discretion, to commence an
interpleader action or seek other judicial relief or orders as it may deem, in its sole
discretion, necessary. The reasonable out-of-pocket costs and expenses (including reasonable
attorneys’ fees and expenses of one counsel) incurred in connection with such proceeding will
be paid by, and will be solely an obligation of, the Grantor.
	 
	(j)	 	Compliance with judicial orders. If at any time the Escrow Agent is served with any
judicial or administrative order, judgment, decree, writ or other form of judicial or
administrative process that in any way affects Escrow Property, including but not limited to
orders of attachment or garnishment or other forms of levies or injunctions or stays relating
to the transfer of Escrow Property (an “Order”), the Escrow Agent is authorized to
comply therewith in any manner as it or its legal counsel of its own choosing deems necessary;
and if the Escrow Agent complies with any such Order, the Escrow Agent will not be liable to
any of the parties hereto or to any other

-11-

 

	 	 	person or entity even though such Order may be subsequently modified or vacated or otherwise
determined to have been without legal force or effect.
	 
	(k)	 	Right to rely on communications. The Escrow Agent will be entitled to conclusively
rely upon any order, judgment, certification, demand, instruction, notice, instrument or other
writing delivered to it hereunder without being required to determine the authenticity or the
correctness of any fact stated therein or the propriety or validity or the service thereof.
The Escrow Agent may act in conclusive reliance upon any instrument or signature believed by
it in good faith to be genuine and may assume that any person purporting to give receipt or
advice to make any statement or execute any document in connection with the provisions hereof
has been duly authorized to do so. When the Escrow Agent acts on any information,
instructions, communications (including, but not limited to, communications with respect to
the delivery of securities or the wire transfer of funds) sent by facsimile, email or other
form of electronic or data transmission, the Escrow Agent, absent gross negligence, willful
misconduct or bad faith, will not be responsible or liable in the event such communication is
not an authorized or authentic communication of the Grantor or the Trustee, as the case may
be, or is not in the form the Grantor or the Trustee sent or intended to send (whether due to
fraud, distortion or otherwise). The Grantor will indemnify the Escrow Agent against any
loss, liability, claim or expense (including reasonable legal fees and expenses of one legal
counsel) it may incur as a result of acting in accordance with any such communication, except
to the extent arising from the Escrow Agent’s gross negligence, willful misconduct or bad
faith.
	 
	(l)	 	Right to request instruction. At any time the Escrow Agent may request an
instruction in writing from the Grantor and the Trustee and may, at its own option, include in
such request the course of action it proposes to take and the date on which it proposes to
act, regarding any matter arising in connection with its duties and obligations hereunder.
The Escrow Agent will not be liable for acting in accordance with such a proposal on or after
the date specified therein; provided that (i) the specified date will be at least five
(5) Business Days after each of the Grantor and the Trustee receives the Escrow Agent’s
request for instructions and its proposed course of action and (ii) prior to so acting, the
Escrow Agent has not received the written instructions requested.
	 
	(m)	 	Liability for Taxes. Except as otherwise set forth herein, the Escrow Agent does not
have any interest in the Escrow Property deposited hereunder but is serving as escrow holder
only and having only possession thereof and nothing herein shall require the Escrow Agent to
pay any taxes. The Grantor will pay or reimburse the Escrow Agent upon request for any
transfer taxes or other taxes relating to the Escrow Property incurred in connection herewith
and will indemnify and hold harmless the Escrow Agent with respect to any amounts that it pays
in the way of such taxes, in each case to the reasonable satisfaction of the Escrow Agent.
Any payments of income from the Escrow Account will be subject to withholding regulations then
in force with respect to United States taxes. The parties hereto will provide the Escrow
Agent with appropriate W-9 forms for tax I.D. number certifications, or W-8 forms for
non-resident alien certifications, as requested. It is understood that the Escrow Agent will
be responsible for income reporting only with respect to income earned on investment of funds
which are a part of the Escrow Property and is not responsible for any other reporting. The
provisions of this Section 2.1(n) will survive the termination of this Agreement or the
earlier resignation or removal of the Escrow Agent.

2.2. Indemnity.

          The Grantor will be liable for and will reimburse and indemnify the Escrow Agent and hold the
Escrow Agent harmless from and against any and all claims, actual losses, liabilities, reasonable
costs, damages or expenses (including reasonable attorneys’ fees and expenses of one legal counsel)

-12-

 

(collectively, “Losses”) arising from or in connection with or related to this
Agreement or being the Escrow Agent hereunder (including but not limited to Losses incurred by the
Escrow Agent in connection with its successful defense, of any claim of gross negligence or willful
misconduct on its part); provided, however, that nothing contained herein will
require the Escrow Agent to be indemnified for Losses caused by its gross negligence, willful
misconduct or bad faith.

          The provisions of this Section 2.2 will survive the termination of this Agreement or the
earlier resignation or removal of the Escrow Agent.

2.3. Removal of Escrow Agent.

	(a)	 	The Grantor may, with notice to the Trustee, remove the Escrow Agent at any time by giving to
the Escrow Agent 15 days’ prior notice in writing signed by the Grantor. The Escrow Agent may
resign at any time by giving to the Grantor and the Trustee 15 days’ prior written notice
thereof.
	 
	(b)	 	Within 5 Business Days after giving the foregoing notice of removal to the Escrow Agent or
receiving the foregoing notice of resignation from the Escrow Agent, the Grantor will appoint
a successor escrow agent. The Grantor will cause any successor escrow agent to assume the
obligations of the Escrow Agent hereunder or to enter into such other escrow and security
agreement as may be acceptable to the Trustee in its sole discretion. If a successor escrow
agent has not accepted such appointment by the end of such 5-Business Day period or such
successor escrow agent has not become so bound, the Escrow Agent may, in its sole discretion,
deliver the Escrow Property to the Trustee at the address provided herein or may apply to a
court of competent jurisdiction for the appointment of a successor escrow agent or for other
appropriate relief. The reasonable out-of-pocket costs and expenses (including reasonable
attorneys’ fees and expenses of one legal counsel) incurred by the Escrow Agent in connection
with such proceeding will be paid by, and be deemed to be solely an obligation of, the
Grantor.
	 
	(c)	 	Upon receipt of the identity of the successor escrow agent, the Escrow Agent will either
deliver the Escrow Property then held hereunder to the successor escrow agent, less the Escrow
Agent’s fees, costs and expenses or other obligations owed to the Escrow Agent, or hold such
Escrow Property (or any portion thereof), pending distribution, until all such fees, costs and
expenses or other obligations owing to the Escrow Agent are paid. Upon delivery of the Escrow
Property to the successor escrow agent, the Escrow Agent will have no further duties,
responsibilities or obligations hereunder.

2.4. Termination.

          This Agreement will automatically terminate upon the distribution of all Escrow Property from
the Escrow Account in accordance with the provisions of Section 1.4 hereof. Section 1.7 hereof,
the provisions of these Terms and Conditions and the Miscellaneous provisions below will survive
termination of this Agreement and/or the resignation or removal of the Escrow Agent.
