agreement, interest rate cap agreement or other financial agreement or arrangement with respect to exposure to interest rates applicable to such Indebtedness if such interest rate agreement has a remaining term in excess of twelve months).

 If any Indebtedness is Incurred under a revolving credit facility and is being given pro forma effect, the interest on such

delivered under this Indenture. 
 On the Issue Date, the Trustee shall, upon receipt of the Issuers’ order (an

(ii) Exchange Notes or private exchange notes for issue only in an Exchange Offer or a private exchange, respectively, pursuant to a Registration Rights Agreement, for a like principal amount of Initial Notes. Such Authentication Order shall

 The Issuers shall
require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or Additional
Interest, if any, or interest on the Notes, and will notify the Trustee, in writing, of any default by the Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to
the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than an Issuer or a Subsidiary) shall have no further liability for the money.
If an Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuers,
the Trustee shall serve as Paying Agent for the Notes.

restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including transfers between or among Depository participants or beneficial owners of interests in any Global
Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial
compliance as to form with the express requirements hereof. Neither the Trustee nor any of its agents shall have any responsibility for any actions taken or not taken by the Depository.

 (j) Automatic Exchange from Restricted Global Note to Unrestricted Global Note. At
the option of the Issuers and upon compliance with the following procedures, beneficial interests in a Restricted Global Note shall be exchanged for beneficial interests in an Unrestricted Global Note. In order to effect such exchange, the Issuers
shall provide written notice to the Trustee instructing the Trustee to (i) direct the Depositary to transfer the specified amount of the outstanding beneficial interests in a particular Restricted Global Note to an Unrestricted Global Note and
provide the Depositary with all such information as is necessary for the Depositary to appropriately credit and debit the relevant Holder accounts and (ii) provide prior written notice to all Holders of such exchange, which notice must include
the date such exchange is proposed to occur, the CUSIP number of the relevant Restricted Global Note and the CUSIP number of the Unrestricted Global Note into which such Holders’ beneficial interests will be exchanged. As a condition to any
such exchange pursuant to this Section 2.06(j), the Trustee shall be entitled to receive from the Issuers and rely upon conclusively without any liability, an Officers’ Certificate and an Opinion of Counsel, in form and in substance
reasonably satisfactory to the Trustee, to the effect that such transfer of beneficial interests to the Unrestricted Global Note shall be effected in compliance with the Securities Act and the terms and conditions of this Indenture. The Issuers may
request from Holders such information it reasonably determines is required in order to be able to deliver such Officers’ Certificate and Opinion of Counsel. Upon such exchange of beneficial interests pursuant to this Section 2.06(j), the
Registrar shall reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Note and the Unrestricted Global Note, respectively, equal to the
principal amount of beneficial interests transferred. Following any such transfer pursuant to this Section 2.06(j) of all of the beneficial interests in a Restricted Global Note, such Restricted Global Note shall be cancelled. 

Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuers shall
issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. An indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and
the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers and/or the Trustee may charge for their expenses in replacing a Note. 

Every replacement Note is a contractual obligation of the Issuers and shall be entitled to all of the benefits of this Indenture equally
and proportionately with all other Notes duly issued hereunder. 
 Section 2.08 Outstanding Notes. 

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it
for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09, a Note
does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note. 
 If a Note is replaced
pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 

  
 -48-









 If the principal amount of any Note is considered paid under Section 4.01, it ceases to
be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuers or a Subsidiary or an
Affiliate of any thereof) holds, on a Redemption Date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

 Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers, or by any Affiliate of the Issuers, shall be
considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so
owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with
respect to the Notes and that the pledgee is not the Issuers or any obligor upon the Notes or any Affiliate of the Issuers or of such other obligor. 
 Section 2.10 Temporary Notes. 
 Until certificates representing Notes
are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the
Issuers consider appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

 Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to
Holders, or beneficial holders, respectively, of Notes under this Indenture. 
 Section 2.11 Cancellation.

 The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to
the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall, at the written direction of the Issuers, cancel
all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of such cancelled Notes in accordance with its customary procedures. The Issuers may not issue new Notes to replace Notes that it
has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12 Defaulted Interest.

 If the Issuers default in a payment of interest or principal on the Notes, to the extent lawful, interest shall accrue on
such overdue principal and interest at a rate that is 2% higher than the then applicable interest rate. Such default interest shall be payable to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in
the Notes. The Issuers 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 Issuers 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 provided in this Section 2.12. The Trustee shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted interest. The Trustee shall promptly notify the Issuers of such special record date. At least 15 days before the special record date, the Issuers (or, upon the
written request of the Issuers, the Trustee in the name and at the expense of the Issuers) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice (which shall be prepared by the Issuers) at his or her address as it
appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid. 

  
 -49-









 Subject to the foregoing provisions of this Section 2.12 and for greater certainty,
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 2.13 CUSIP and ISIN Numbers. 
 The Issuers in issuing the Notes may use CUSIP and/or ISIN numbers (if then generally in use) and, if so, the Trustee shall use CUSIP and/or ISIN numbers in notices of redemption as a convenience to
Holders; provided, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption and that reliance may be placed only on the
other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers will as promptly as practicable notify the Trustee in writing of any change in the CUSIP or
ISIN numbers. 
 ARTICLE 3

accordance with the applicable procedures of DTC. In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than
60 days prior to the Redemption Date by the Registrar and Paying Agent from the outstanding Notes not previously called for redemption or purchase.

 Notes redeemed in part shall be redeemed only in integral multiples of $1,000, and no Notes
of $2,000 or less shall be redeemed in part, except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed.
Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 
 Section 3.03 Notice of Redemption. 
 The Issuers shall mail or cause
to be mailed by first-class mail notices of redemption at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address or otherwise in accordance with
the procedures of the Depository, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 14; provided that in connection with a Special
Mandatory Redemption pursuant to Section 3.09 hereof, the redemption notice may be mailed less than 30 days prior to the Redemption Date. Notices of redemption may not be conditional, provided that any notice delivered pursuant to
Section 3.07(c) may, at an Issuer’s discretion, be subject to completion of an Equity Offering provided further than any notice of redemption delivered pursuant to Section 3.09(f) shall be subject to completion of the AboveNet
Acquisition. 
 The notice shall identify the Notes to be redeemed (including CUSIP and/or ISIN numbers) and shall state:

 (a) the Redemption Date; 

(b) the redemption price (or manner of calculation if not then known); 

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed
and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent not redeemed will be issued in the name of
the Holder of the Notes upon cancellation of the original Note; 
 (d) the name and address of the Paying Agent;

 (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price

 At the Issuers’ request, the Trustee

mailed to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and a copy of the notice containing the information required
in the preceding paragraph. 

  
 -51-









 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable
on the Redemption Date at the redemption price. The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or
any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05, on and after the Redemption Date,
interest ceases to accrue on Notes or portions thereof called for redemption. 
 Section 3.05 Deposit of Redemption or
Purchase Price. 
 Prior to 10:00 a.m. (New York City time) on the redemption or purchase date, the Issuers shall
deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest (including Additional Interest, if any) on all Notes to be redeemed or purchased on that date. The Trustee
or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest on, all Notes to be
redeemed or purchased. 
 If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or
purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any
accrued and unpaid interest to the redemption or purchase date shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or purchase shall not be so paid upon
surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent
lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes. 
 Section 3.06 Notes Redeemed or Purchased in Part. 
 Upon surrender of
a Note that is redeemed or purchased in part, the Issuers shall issue and the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note
surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that,
notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officers’ Certificate is required for the Trustee to authenticate such new Note.

 Other than as described in Section 3.09, the Issuers are not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the
Issuers may be required to offer to purchase the Notes as described in Section 4.09 and Section 5.01. 

Section 3.09 Special Mandatory Redemption. 
 (a) In the event that any of the events in Section 3.09(b) below occur, then the Company shall be required to redeem all of the Notes (the “Special Mandatory
Redemption”) using the Escrowed Funds at a redemption price equal to the aggregate outstanding principal amount of the Notes and a special mandatory redemption fee of 1% of the aggregate outstanding principal amount of the
Notes, plus accrued and unpaid interest to, but not including, the redemption date (the “Special Mandatory Redemption Price”). 
 (b) The Company shall be required to make a Special Mandatory Redemption if: 
 (i) AboveNet Acquisition and the other conditions to the release of the Escrowed Funds set forth in the Escrow Agreement, including the Assumption, shall not have occurred by July 30, 2012

release of the Escrowed Funds set forth in the Escrow Agreement, including the Assumption, have not occurred on or prior to the date that is three Business Days prior to the Outside Date (as may be extended from time to time) or if an Escrow
Termination Notice has been delivered to the Escrow Agent, then the Company will cause a notice of a Special Mandatory Redemption to be delivered to each Holder of Notes, or to DTC in accordance with its procedure applicable to global notes, no

franchise or the existence (corporate or otherwise) of any such Restricted Subsidiary if the Board of Directors of the Company shall determine that the preservation thereof is no longer necessary or desirable in the conduct of the business of the
Company and its Restricted Subsidiaries as a whole and that the loss thereof could not reasonably be expected to have a material adverse effect on the ability of the Issuers to perform their obligations hereunder; and provided,
further, however, that the foregoing shall not prohibit a sale, transfer or conveyance of a Restricted Subsidiary or any of its assets in compliance with the terms of this Indenture.

 (B) any event that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary (except for any pledge of such Indebtedness constituting a Permitted Lien until
the pledgee commences actions to foreclose on such Indebtedness) will be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause
(6); 
 (7) the Guarantee by the Company or any Guarantor of Indebtedness of the Company or a Restricted
Subsidiary that was permitted to be Incurred by another provision of this Section 4.03;

Company or any other Restricted Subsidiary in any way other than Standard Securitization Undertakings. 
 (c) For purposes of
determining compliance with this Section 4.03, in the event that any proposed Indebtedness meets the criteria of more than one of the categories described in clauses (1) through (16) of Section 4.03(b), or is entitled to be
Incurred pursuant to Section 4.03(a), the Company will be permitted to classify, and may later reclassify, such item of Indebtedness or a part thereof in any manner that complies with this covenant. Notwithstanding the foregoing, Indebtedness
under the New Credit Facilities outstanding on the date of the Assumption, if any, will be deemed to have been Incurred on such date in reliance on the exception provided by Section 4.03(b)(1) and shall not be reclassified. 

(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 (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. 
 (e) The principal amount of any Indebtedness Incurred to
refinance other Indebtedness, if Incurred in a different currency from this 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. 
 (f) The accretion of original issue discount shall be deemed not to be an
Incurrence of Indebtedness. 

  
 -57-









 (g) The Company will not Incur any Indebtedness that is contractually subordinate in right
of payment to any other Indebtedness of the Company unless it is contractually subordinate in right of payment to the Notes at least to the same extent. The Company will not permit any co-issuer or any Guarantor to Incur any Indebtedness that is
contractually subordinate in right of payment to any other Indebtedness of any co-issuer or such Guarantor, as the case may be, unless it is contractually subordinate in right of payment to the Notes or such Guarantor’s Note Guarantee, as the
case may be, at least to the same extent. For purposes of this Indenture, no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuers or any Guarantor, as applicable, solely by reason
of any Liens or Guarantees arising or created in respect thereof. 
 Section 4.04 Limitation on Restricted Payments.

Subsidiary); 

  

	 	(iii)	call for redemption or make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, prior to the Stated Maturity
thereof, any Indebtedness that is subordinated in right of payment to the Notes or any Note Guarantee except (a) in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year
of the date of such payment, purchase, repurchase or other acquisition or (b) intercompany Indebtedness permitted to be Incurred pursuant to Section 4.03(b)(6); or 


 

	 	(iv)	make any Investment (other than a Permitted Investment) in any Person; unless, at the time of and after giving pro forma effect to such Restricted Payment:


 (1) no Default or Event of Default will have occurred and be continuing or would occur as a
consequence thereof; 
 (2) the Company could Incur at least $1.00 of additional Indebtedness pursuant to the
Consolidated Leverage Ratio test set forth in Section 4.03(a); and 
 (3) such Restricted Payment, together

 (A) the aggregate Consolidated Cash Flow accrued in the period beginning on
the first day of the quarter beginning on July 1, 2012, and ending on the last day of the most recent quarter for which internal financial statements are available prior to the date of such proposed Restricted Payment (or, if such Consolidated
Cash Flow for such period is a deficit, less 100% of such deficit), less (y) 1.5 times consolidated interest expense during such period; plus 
 (B) the aggregate net cash proceeds received by the Company after the date of the AboveNet Acquisition is consummated as a contribution to its common equity capital or from the issue or sale of Equity

to, or Indebtedness held by, a Subsidiary of the Company); plus 
 (C) with respect to Investments (other than
Permitted Investments) made by the Company and the Restricted Subsidiaries after the date of the AboveNet Acquisition is consummated, an amount equal to the net reduction in such Investments in any Person (except, in each case, to the extent any
such amount is included in the calculation of Consolidated Net Income), resulting from repayment to the Company or any Restricted Subsidiary of loans or advances or from the receipt of net cash proceeds from the sale of any such Investment, from the
release of any Guarantee (except to the extent any amounts are paid under such Guarantee) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, not to exceed, in each case, the amount of such Investments previously made by
the Company or any Restricted Subsidiary in such Person; plus 
 (D) $180 million. 

(b) The provisions of Section 4.04(a) shall not prohibit the following; provided that, in the case of clauses (7) and
(8) below only, no Default has occurred and is continuing or would be caused thereby:

(2) the payment of any dividend or other distribution by a Restricted Subsidiary to all the holders of its Equity
Interests on a pro rata basis; 
 (3) any Restricted Payment in exchange for, or out of the net cash proceeds of

proceeds that are utilized for such Restricted Payment will be excluded from Section 4.04(a)(iii)(b); 

  
 -59-

of, Permitted Refinancing Indebtedness; 
 (5) the repurchase of Capital Stock deemed to occur upon the exercise
of options or warrants to the extent that such Capital Stock represents all or a portion of the exercise price thereof and applicable withholding taxes, if any; 
 (6) the payment of cash in lieu of fractional Equity Interests pursuant to the exchange or conversion of any exchangeable or convertible securities; provided, that such payment shall not be for the
purpose of evading the limitations of this covenant (as determined by the Board of Directors of the Company in good faith);

agreement entered into in the ordinary course of business; or, prior to the Company’s initial public offering, a distribution or dividend, directly or indirectly, to any of the Company’s direct or indirect parent companies for the purpose
of enabling CII to effect a repurchase, redemption or other acquisition or retirement of the Equity Interests in CII from one or more of its equity investors that fail to comply with their funding commitments under the CII Limited Liability Company
Agreement; provided that the aggregate price paid, or distributed or paid out as a dividend under this clause (8) in any calendar year will not exceed $7.5 million (with unused amounts in any calendar year being carried over to succeeding
years) or, in the event any unused amounts of any previous year are being carried over, $15 million; 
 (9) the
declaration and payment of dividends on the Company’s Equity Interests (or a Restricted Payment to any direct or indirect parent to fund a payment of dividends on such entity’s Equity Interests), following the first public equity offering

loans to, the Parent in amounts required for the Parent to pay, in each case without duplication, (a) franchise taxes and other fees, taxes and expenses required to maintain their corporate existence; (b) foreign, federal, state and local
income taxes, to the extent such income taxes are (i) attributable to the income of the Company and its Restricted Subsidiaries and (ii) required to be paid by the Parent, and only for so long as the Company is treated as a pass-through
entity for U.S. federal income tax purposes; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that the Company and its Restricted Subsidiaries would be required to pay in respect of its foreign,
federal, state and local taxes for such fiscal year were the Company and its Restricted Subsidiaries to pay such taxes separately from any such parent entity; (c) customary salary, bonus and other benefits payable to officers and employees of
the Parent to the extent such salaries, bonuses and other benefits are attributable to the ownership or operation of the Company and its Restricted Subsidiaries; (d) general corporate operating and overhead costs and expenses of the Parent to

 (c) The amount of all Restricted Payments (other than cash) will be
the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued to or by the Company or such Subsidiary, as the case may be, pursuant to the Restricted Payment. 

Section 4.05 Limitation on Transactions with Affiliates. 

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly 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, make, amend, renew or extend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for
the benefit of, any of their Affiliates (each, an “Affiliate Transaction”), unless: 
  

	 	(1)	such Affiliate Transaction is on fair and reasonable terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have
been obtained in a comparable arm’s-length transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company or any Restricted Subsidiary; and 


 

	 	(2)	the Company delivers to the Trustee: 

  

	 	(a)	with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25 million, a Board Resolution
attached to an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant and that such Affiliate Transaction or series of related Affiliate Transactions has been
approved by a majority of the Disinterested Members; and 

  

	 	(b)	with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50 million, an opinion issued by

view. 


  
 -61-









 (b) The following items will be deemed not to be Affiliate Transactions and, therefore, will
not be subject to the provisions of Section 4.05(a): 
  

	 	(1)	transactions between or among the Company and/or its Restricted Subsidiaries; 


 

	 	(2)	Restricted Payments that are permitted under Section 4.04;

thereto or renewal or replacement thereof, as long as such agreement or arrangement, as so amended, modified, supplemented, renewed or replaced, taken as a whole, is not materially more disadvantageous to the Company and the Restricted Subsidiaries
than the agreement or arrangement in existence on the Issue Date as determined by the Disinterested Members of the Board of Directors of the Company evidenced by a Board Resolution; 


 

	 	(5)	payments by the Company (and any direct or indirect parent thereof) and its Subsidiaries pursuant to tax sharing agreements among the Company (and any such parent) and
its Subsidiaries on customary terms to the extent attributable to the ownership or operation of the Company and its Subsidiaries; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that the Company,
its Restricted Subsidiaries and its Unrestricted Subsidiaries (to the extent of amounts received from Unrestricted Subsidiaries) would be required to pay in respect of foreign, federal, state and local taxes for such fiscal year were the Company and
its Subsidiaries (to the extent described above) to pay such taxes separately from any such parent entity; 

  

	 	(6)	payment of reasonable and customary fees to, and reasonable and customary indemnification arrangements and similar payments on behalf of, directors of the Company or

Subsidiary with officers and employees of the Company or any Subsidiary thereof and the payment of compensation to officers and employees of the Company or any Subsidiary thereof (including amounts paid pursuant to employee benefit plans, employee
stock option or similar plans), so long as such agreement or payment have been approved by a majority of the Disinterested Members. 

 Section 4.06 Limitation on Liens. 
 The Company will not, and will not
permit any Restricted Subsidiary to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired. 

Section 4.07 Limitation on Sale of Assets. 
 (a) The Company will not, and will not permit any Restricted Subsidiary to, consummate an Asset Sale unless: 
  

	 	(1)	the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the
assets or Equity Interests issued or sold or otherwise disposed of; 


  
 -62-










	 	(2)	at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of: 


 

	 	(a)	Cash Equivalents (including any Cash Equivalents received from the conversion within 180 days of such Asset Sale of any securities, notes or other obligations received
in consideration of such Asset Sale); 

  

	 	(b)	Replacement Assets; 

  

	 	(c)	any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries 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 the greater of (x) 1.0% of total assets and (y) $10 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); or 

  

	 	(d)	any combination of the consideration specified in clauses (a) and (b); and 


 

	 	(3)	in the case of an Asset Sale of Collateral, all consideration from such Asset Sale that is not in the form of Cash Equivalents is pledged as Collateral to secure the
Notes concurrently with or promptly after the acquisition. 

 (b) Any Net Available Cash received by the Company
or any Restricted Subsidiary from any Asset Sale: 
  

	 	(1)	in the case of any Asset Sale of Collateral, (A) shall be reinvested within 360 days in Replacement Assets; provided that (x) to the extent the assets subject
to such Asset Sale were Collateral, such newly acquired assets shall also be Collateral and (y) the purchase of the Replacement Assets is consummated no later than (i) the 360th day after such Asset Sale or (ii) so long as a binding
agreement with respect to the purchase of Replacement Assets is entered into within 360 days after the Asset Sale, 90 days after the date of such binding agreement, or (B) shall otherwise be used to make an Offer to Purchase (as described
below) in accordance with the following paragraph; or 

  

	 	(2)	in the case of any Asset Sale of assets not constituting Collateral, may be applied (A) as provided in the immediately preceding clause (1) above or
(B) within 365 days of receipt of such Net Available Cash, to permanently reduce any Indebtedness constituting Indebtedness of a non-Guarantor Subsidiary or to permanently reduce any senior Indebtedness of the Issuers or any Guarantor (in each
case owing to a Person other than the Company or any Affiliate of the Company) (and, if the obligation repaid is revolving credit Indebtedness, to correspondingly reduce loan commitments with respect thereto). 


  
 -63-









 (c) The amount of such Net Available Cash required to be applied (or to be committed to be
applied) during such 365 day period as set forth in Section 4.07(b) and not applied (or committed to be applied) as so required by the end of such period shall constitute “Excess Proceeds.” If, as of the first day of any
calendar month, the aggregate amount of Excess Proceeds totals at least $50 million, the Company must commence, not later than the 15th Business Day of such month, and consummate an Offer to Purchase, from the Holders and all holders of other Pari
Passu Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase with the proceeds of sales of assets, the maximum principal amount of Notes and such other Pari Passu Debt that may be purchased out of
the Excess Proceeds; provided that the amount of Excess Proceeds required to be used to make an Offer to Purchase pursuant to this paragraph shall be reduced by any mandatory prepayments made under any Series of Pari Passu Debt in respect of such
Excess Proceeds (and which prepayments shall not be in excess of such Series pro rata share of such Excess Proceeds). The offer price in any such Offer to Purchase will be equal to 100% of the principal amount (or accreted value, if applicable) of
the Notes and such other Pari Passu Debt plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest
payment date, and will be payable in cash. To the extent that any Excess Proceeds remain after consummation of an Offer to Purchase pursuant to this Section 4.07, the Company may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture, and those Excess Proceeds shall no longer constitute “Excess Proceeds.” 
 (d) Except in
the case of an Asset Sale of Collateral, for the purposes of this Section 4.07, the following are deemed to be Cash Equivalents: the assumption of (i) Indebtedness of the Company (other than Disqualified Stock or Indebtedness that is by
its terms subordinated in right of payment to the Notes); (ii) Indebtedness of any Restricted Subsidiary (other than Indebtedness of a Guarantor that is by its terms subordinated in right of payment to the Notes or Disqualified Stock of any
Guarantor) or (iii) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities, Indebtedness that is by its
terms subordinated to the Notes or any Note Guarantee and liabilities to the extent owed to the Company or any Subsidiary of the Company) and, in each case, the full and unconditional release of the Company or such Restricted Subsidiary from all
liability on such Indebtedness in connection with such Asset Sale. 
 Section 4.08 Future Subsidiary Note
Guarantees. 
 (a) If the Company or any Restricted Subsidiary acquires or creates another Domestic Subsidiary on or after
the date of the Assumption, then that newly acquired or created Domestic Subsidiary must become a Guarantor and (i) execute a supplemental indenture, (ii) deliver an Opinion of Counsel to the Trustee, (iii) execute supplements to the
applicable Security Documents in order to grant a Lien in the Collateral owned by such entity to the same extent as that set forth in this Indenture and the Security Documents, in each case, within 30 days following such acquisition or creation and
(iv) take all actions required by the Security Documents to perfect such Lien, provided that the obligation of such Domestic Subsidiary shall be subject to its obtaining prior approval of any by State PUC if so required by applicable law.

 (b) The Company will not permit any Restricted Subsidiary, directly or indirectly, to Guarantee any Indebtedness of the
Issuers or any Guarantor unless such Restricted Subsidiary (a) is a Guarantor or (b) within ten days executes and delivers to the Trustee an Opinion of Counsel and a supplemental indenture providing for the Guarantee of the payment of the
Notes by such Restricted Subsidiary, which Guarantee will rank senior in right of payment to or equally in right of payment with such Subsidiary’s Guarantee of such other Indebtedness. 

Section 4.09 Purchase of Notes upon a Change of Control. 

(a) Unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding Notes as
described in Section 3.03, the Issuers must commence, within 30 days of the occurrence of a Change of Control, and consummate an Offer to Purchase for all Notes then outstanding, at a purchase price in cash equal to 101% of the aggregate
principal amount of the Notes repurchased, plus accrued and unpaid interest and Additional Interest, if any, thereon, to the date of repurchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the
relevant interest payment date. 

  
 -64-









 (b) The Issuers will not be required to make an Offer to Purchase upon a Change of Control
if a third party makes the Offer to Purchase in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to an Offer to Purchase made by the Issuers and purchases all Notes validly tendered
and not withdrawn under such Offer to Purchase. 
 Section 4.10 Limitation on Sale and Leaseback Transactions.

 The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction;
provided that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction with respect to assets or properties comprising Collateral if the aggregate amount of such assets or properties does not exceed $50,000,000 and
provided further that the Company or any Restricted Subsidiary may enter into a Sale and Leaseback Transaction with respect to assets or properties other than Collateral if: 

 

	 	(1)	the Company or such Restricted Subsidiary, as applicable, could have (a) Incurred Indebtedness in an amount equal to the Attributable Debt relating to such Sale
and Leaseback Transaction and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.06; 

  

	 	(2)	the gross cash proceeds of that Sale and Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of that Sale and
Leaseback Transaction; and 

  

	 	(3)	the transfer of assets in that Sale and Leaseback Transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with
Section 4.07. 

 Section 4.11 Limitation on Dividend and Other Payment Restrictions Affecting
Restricted Subsidiaries. 
 (a) The Company will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
  

	 	(1)	pay dividends or make any other distributions on its Capital Stock (or with respect to any other interest or participation in, or measured by, its profits) to the
Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a
restriction on the ability to make distributions on Capital Stock); 

  

	 	(2)	pay any liabilities owed to the Company or any Restricted Subsidiary; 

  

	 	(3)	make loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any
Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or 


 

	 	(4)	transfer any of its properties or assets to the Company or any Restricted Subsidiary. 


(b) Section 4.11(a) will not apply to encumbrances or restrictions:

(including the Unsecured Notes) or any other agreements in effect on the Issue Date and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings thereof; provided that the encumbrances
and restrictions in any such amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings, taken as a whole, are not, as determined by the Company in good faith, materially more restrictive
than those contained in, as the case may be, the New Credit Facilities or the Security Documents as in effect on the date of the Assumption or Existing Indebtedness or such other agreements as in effect on the Issue Date; 


 

	 	(2)	set forth in this Indenture, the Notes and the Note Guarantees;

	 	(4)	with respect to any Person or the property or assets of a Person acquired by the Company or any Restricted Subsidiary existing at the time of such acquisition and not
incurred in connection with or in contemplation of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so
acquired, and any amendments, modifications, restatements, renewals, extensions, supplements, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such amendments, modifications, restatements,
renewals, extensions, supplements, refundings, replacements or refinancings, taken as a whole, are not, as determined by the Company in good faith, materially more restrictive than those in effect on the date of the acquisition;


  

	 	(5)	that restrict in a customary manner the subletting, assignment or transfer of any property or asset that is a lease, license, conveyance or contract or similar property
or asset; 

  

	 	(6)	existing by virtue of any transfer of, agreement to transfer, option or right with respect to, or Lien on, any property or assets of the Company or any Restricted

property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary, as determined by the Company in good faith; 


 

	 	(8)	that restrict distributions or transfer by a Restricted Subsidiary if such restrictions exist under, by reason of or with respect to any agreement for the sale or other
disposition of all or substantially all of the Capital Stock of, or property and assets of, that Restricted Subsidiary and are pending such sale or other disposition; 


 

	 	(9)	on cash or other deposits or net worth, which encumbrances or restrictions are imposed by customers or suppliers or required by insurance, surety or bonding companies,
in each case, under contracts entered into in the ordinary course of business; 

  

	 	(10)	arising from customary provisions in joint venture agreements and other similar agreements entered into in the ordinary course of business and which the Board of
Directors of the Company determines in good faith will not adversely affect the Issuers’ ability to make payments of principal or interest on the Notes; 


  
 -66-










	 	(11)	arising from purchase money obligations Incurred in compliance with Section 4.03(b)(4) that impose restrictions of the nature described in Section 4.11(a)(4)
above on the assets acquired; and 

  

	 	(12)	existing under, by reason of, or with respect to Indebtedness of any Restricted Subsidiary that is a Foreign Subsidiary; provided that the Company’s Board of
Directors determines in good faith at the time such encumbrances or restrictions are created that they do not adversely affect the Issuers’ ability to make prepayments of principal or interest on the Notes. 


Section 4.12 Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary; provided that:

  

	 	(1)	any Guarantee by the Company or any Restricted Subsidiary of any Indebtedness of the Subsidiary being so designated will be deemed to be an Incurrence of Indebtedness
by the Company or such Restricted Subsidiary, as the case may be, at the time of such designation, and such Incurrence of Indebtedness would be permitted under Section 4.03; 


 

	 	(2)	the aggregate Fair Market Value of all outstanding Investments owned by the Company and the Restricted Subsidiaries in the Subsidiary being so designated (including any
Guarantee by the Company or any Restricted Subsidiary of any Indebtedness of such Subsidiary) will be deemed to be an Investment made as of the time of such designation and that such Investment would be permitted under Section 4.04;


  

	 	(3)	such Subsidiary does not hold any Capital Stock or Indebtedness of, or own or hold any Lien on any property or assets of, or have any Investment in, the Company or any
Restricted Subsidiary; 

  

	 	(4)	the Subsidiary being so designated: 

  

	 	(i)	is not party to any agreement, contract, arrangement or understanding with the Company or any Restricted Subsidiary unless the terms of any such agreement, contract,
arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Company; 


 

	 	(ii)	is a Person with respect to which neither the Company nor any Restricted Subsidiary has any direct or indirect obligation (i) to subscribe for additional Equity
Interests or (ii) to maintain or preserve such Person’s financial condition or to cause such Person to achieve any specified levels of operating results; and 


 

	 	(iii)	has not Guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Company or any Restricted Subsidiary, except to the extent
such Guarantee or credit support would be released upon such designation; and 


  
 -67-










	 	(5)	no Default or Event of Default would be in existence following such designation. 

 Any designation of a Restricted Subsidiary as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee the Board Resolution giving effect to such designation and an
Officers’ Certificate and an Opinion of Counsel certifying that such designation complied with the preceding conditions and was permitted by this Indenture. If, at any time, any Unrestricted Subsidiary (x) would fail to meet any of the
preceding requirements described in clause (4) above, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture, and any Indebtedness, Investments, or Liens on the property, of such Subsidiary will be deemed to be
Incurred or made by a Restricted Subsidiary as of such date, and if such Indebtedness, Investments or Liens are not permitted to be Incurred or made as of such date under this Indenture, the Issuers will be in default under this Indenture.

 (b) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that: 
  

	 	(1)	such designation will be deemed to be an Incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation will only be permitted if such Indebtedness is permitted under Section 4.03; 

  

	 	(2)	all outstanding Investments owned by such Unrestricted Subsidiary will be deemed to be made as of the time of such designation and such designation will only be
permitted if such Investments would be permitted under Section 4.04; 

  

	 	(3)	all Liens upon property or assets of such Unrestricted Subsidiary existing at the time of such designation would be permitted under Section 4.06; and


  

	 	(4)	no Default or Event of Default would be in existence following such designation. 

 Section 4.13 Business Activities. 
 The Company will not, and will not
permit any Restricted Subsidiary to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Company and the Restricted Subsidiaries taken as a whole. 

Section 4.14 Payments for Consent. 
 The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid to all Holders that may legally participate in the transaction, in the structure proposed
by the Company, and is paid to all such Holders of the Notes that consent, waive or agree to amend in the time frame and in the manner set forth in the solicitation documents relating to such consent, waiver or agreement. 

Section 4.15 Provision of Financial Information. 
 (a) The Issuers will (i) furnish to the Trustee, (ii) upon request, furnish to beneficial owners and prospective investors and (iii) prior to the consummation of the Exchange Offer, make
publicly available on its website, a copy of all of the information and reports referred to in clauses (1) and (2) below within the time periods specified in the Commission’s rules and regulations: 

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission
on Forms 10-Q and 10-K if the Issuers were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on
the annual financial statements by the Company’s certified independent accountants; and 

  
 -68-









 (2) all current reports that would be required to be filed with the
Commission on Form 8-K if the Issuers were required to file such reports. 
 (b) After consummation of the Exchange Offer
contemplated by the Registration Rights Agreement, whether or not required by the Commission, the Issuers will comply with the periodic reporting requirements of the Exchange Act and will file the reports specified in Section 4.15(a) with the
Commission within the time periods specified in Section 4.15(a) unless the Commission will not accept such a filing. The Issuers will not take any action for the purpose of causing the Commission not to accept any such filings. If,
notwithstanding the foregoing, the Commission will not accept any Issuers’ filings for any reason, such Issuer will deliver a copy of such reports to the Trustee and post the reports referred to in the preceding paragraph on its website within
the time periods that would apply if such Issuer were required to file those reports with the Commission. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such
shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to
rely exclusively on Officer’s Certificates). 
 (c) If the Company has designated as Unrestricted Subsidiaries any of its
Subsidiaries that is a Significant Subsidiary or that, when taken together with all other Unrestricted Subsidiaries, would be a Significant Subsidiary, then the quarterly and annual financial information required by this Section 4.15 will
include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial
condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries. 

(d) Notwithstanding the foregoing, if any parent of the Company becomes a Guarantor, the reports, information and other documents
required to be filed and provided as described above may be those of the parent, rather than those of the Company, so long as such filings would satisfy the Commission’s requirements. 

(e) So long as any Notes remain outstanding, the Issuers and Guarantor will furnish to the Holders and to prospective investors, upon
their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

Section 4.16 Statement by Officers as to Default. 
 (a) The Issuers will deliver to the Trustee, on or before a date not more than 90 days after the end of each fiscal year of the Issuers, an Officers’ Certificate, as to compliance herewith,
including whether or not, after a review of the activities of the Issuers during such year and of the Issuers and each Guarantor’s performance under this Indenture, to the best knowledge, based on such review, of the signers thereof, the
Issuers and each Guarantor have fulfilled all of their respective obligations and are in compliance with all conditions and covenants under this Indenture throughout such year, as the case may be, and, if there has been a Default specifying each
Default and the nature and status thereof and any actions being taken by the Issuers and the Guarantors with respect thereto. 

(b) When any Default or Event of Default has occurred and is continuing, the Issuers shall deliver to the Trustee by registered or
certified mail or facsimile transmission of an Officers’ Certificate specifying such Default or Event of Default, within five Business Days after becoming aware of the occurrence of such Default or Event of Default.

 Section 4.17 Maintenance of Insurance.

 (a) At all times, at its own expense, the Company shall cause to be carried and maintained by all the Grantors with reputable
insurers, insurance (including property insurance, liability insurance, business interruption insurance, and workers’ compensation insurance) of the kinds and in the amounts and with deductibles as are customarily maintained by prudent
businesses in similar circumstances, carrying on similar businesses or having comparable properties and reasonably acceptable to the Collateral Agent. 
 (b) The Collateral Agent shall be named as an additional insured and loss payee (as appropriate) with respect to all insurance maintained by the Grantors on the Collateral. Upon request of the Collateral
Agent, the Company shall furnish to the Collateral Agent such information relating to its property and property of the other Grantors and liability insurance carriers as may be reasonably requested from time to time. 

(c) No provision of this Section 4.17 shall impose on the Collateral Agent or the Trustee any duty or obligation to verify the
existence or adequacy of the insurance coverage maintained by the Company or the other Grantors, nor shall the Collateral Agent or the Trustee be responsible for any representations or warranties made by or on behalf of the Company to any insurance
company or underwriter. Any failure on the part of the Collateral Agent, the Trustee or the Holders to pursue or obtain the evidence of insurance required by this Section 4.17 from the Company or the other Grantors and/or failure of the
Collateral Agent, the Trustee or Holders to point out any non-compliance of such evidence of insurance shall not constitute a waiver of any of the insurance requirements in this Section 4.17. 

(d) During the existence and continuation of an Event of Default, all insurance proceeds or condemnation proceeds received by the Company
or any of its Subsidiaries in respect of any Collateral shall, if so directed by the Collateral Agent, be held in the Loan and Notes Collateral Account held by the Collateral Agent for the benefit of the Holders pending application of such proceeds
as permitted by this Indenture, the Intercreditor Agreement and the other Security Documents. 
 Section 4.18
Maintenance of Properties. 
 Each Issuer will, and will cause each of its Subsidiaries to, maintain or cause to be
maintained in the ordinary course of business in good repair, working order and condition, normal wear and tear and disposal of obsolete equipment excepted, all properties used or useful in its business (whether owned or held under lease), and from
time to time make or cause to be made all needed and appropriate repairs, renewals, replacements, additions, betterments, and improvements thereto, except where the failure to do so could not reasonably be expected to have a material adverse effect.

 Section 4.19 Suspension of Certain Covenants. 

(a) Following the first day of a Covenant Suspension and ending on a Reversion Date (such period a “Suspension Period”),
the Company and its Restricted Subsidiaries will not be subject to the provisions of the Suspended Covenants. 

  
 -70-









 (b) If at any time the Notes cease to have such Investment Grade Rating by either Rating
Agency or if a Default or Event of Default occurs and is continuing, then the Suspended Covenants will, from such date and thereafter be reinstated as if such covenants had never been suspended (the “Reversion Date”) and be
applicable pursuant to the terms of this Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of this Indenture), unless and until the Notes subsequently attain an Investment Grade
Rating from both Ratings Agencies and no Default or Event of Default is in existence (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Rating from both Ratings Agencies and
no Default or Event of Default is in existence); provided, however, that no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Notes or the Guarantees with respect to the Suspended Covenants based on,
and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising
prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. 

(c) On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to
one of the clauses (other than pursuant to Section 4.03(b)(2) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Indebtedness Incurred prior to the Suspension
Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to Section 4.03(b) such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is
classified as permitted under Section 4.03(b)(2). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 will be made as though the covenants described under
Section 4.04 had been in effect since the 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
Section 4.04(a) to the extent set forth in such covenant. 
 Section 4.20 Escrow of Funds. 

(a) Concurrently with the execution and delivery of this Indenture (i) the Company shall cause to be deposited in an escrow account
maintained with The Bank of New York Mellon Trust Company, N.A., as escrow agent (in such capacity, the “Escrow Agent”) (such account referred to as the “Escrow Account”) $762,916,666.67 (such amount referred to as
the “Initial Deposit”) and (ii) the Company, the Trustee and the Escrow Agent shall enter into an Escrow Agreement to be dated as of the Issue Date (the “Escrow Agreement”). The Initial Deposit shall be in an
amount sufficient to redeem in cash the entire aggregate principal amount of the Notes at a redemption price equal to 100% of the principal amount thereof and a special mandatory redemption fee of 1% of the aggregate principal amount of the
outstanding Notes, plus accrued and unpaid interest thereon to, but excluding, July 30, 2012. 
 (b) the Company agrees
that (i) the terms of the Escrow Agreement shall exclusively control the conditions under which and procedures pursuant to which the Escrowed Funds shall be released and (ii) it will not attempt to have the Escrowed Funds released from the
Escrow Account except in accordance with the Escrow Agreement. In the case of a conflict between the terms of this Indenture and the Escrow Agreement, the Escrow Agreement shall govern. 

Section 4.21 Activities Prior to the Escrow Release. 

Notwithstanding anything else to the contrary contained herein: 

  
 -71-









 (a) prior to the Assumption, Zayo Escrow Corporation’s primary activities shall be
limited to (i) issuing the Notes and the Unsecured Notes, (ii) to the extent permitted, issuing Capital Stock to, and receiving capital contributions from, Zayo Group, LLC or any of its Subsidiaries, (iii) performing its obligations
in respect of the Notes and the Unsecured Notes, this Indenture, the indenture governing the Unsecured Notes and the Escrow Agreement, (iv) granting Liens in favor of the Holders of the Notes and the Unsecured Notes, (v) consummating the
Assumption and redeeming the Notes and the Unsecured Notes, if applicable, and (vi) conducting such other activities as are necessary or appropriate to carry out the foregoing activities described above; 

(b) prior to the Assumption, Zayo Escrow Corporation shall not own, hold or otherwise have any interest in any assets other than the
Escrow Account, cash and Cash Equivalents; and 
 (c) prior to the Assumption, Zayo Escrow Corporation will not engage in any
business activity or enter into any transaction or agreement (including, without limitation, making any Restricted Payment, Incurring any Indebtedness other than the Notes and the Unsecured Notes, incurring any Liens except in favor of the holders
of the Notes and the Unsecured Notes, entering into any merger, consolidation or sale of all or substantially all of its assets or engaging in any transaction with its Affiliates) except as is necessary to effectuate the Assumption. 

Section 4.22 Covenant Compliance Prior to the Escrow Release. 

(a) To the extent Zayo Group, LLC or any Restricted Subsidiary has Incurred Indebtedness, made any Restricted Payments, consummated any
Asset Sale or otherwise taken any action or engaged in any activities during the period beginning on the Issue Date and ending on the date of the Assumption, such actions and activities will be treated and classified under this Indenture (including
but not limited to (i) impacting relevant baskets and (ii) determining whether a Default or Event of Default would have occurred) as if this Indenture and the covenants set forth therein had applied to the Company and the Restricted
Subsidiaries of the Company during such period; provided that no such Default or Event of Default will be deemed to have occurred if such Default or Event of Default no longer exists on the date of the Assumption. For purposes of the foregoing, all
Restricted Subsidiaries shall be deemed to be Restricted Subsidiaries for the period from the Issue Date through the date of the Assumption. 
 (b) Notwithstanding anything to the contrary herein, for all purposes of this Indenture, each transaction or event constituting part of the AboveNet Acquisition shall be deemed to have occurred and been
effective on the Issue Date as if it had occurred simultaneously with the issuance of the Notes issued on the Issue Date, but, for the avoidance of doubt, the payment of the acquisition consideration pursuant to the AboveNet Acquisition Agreement
shall not be deemed to be a Restricted Payment hereunder.

 (b) all Events of Default, other than the
non-payment of principal of, premium, if any, and interest on the Notes which have become due solely by such declaration of acceleration, have been cured or waived. 
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
 Section 6.03 Other Remedies. 
 If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture or any Security Document. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 

The Holders of not less than a majority in aggregate principal amount of the Notes outstanding may on behalf of the Holders of all
outstanding Notes waive any past Default under this Indenture and its consequences, except a Default in the payment of the principal of, premium, if any, or interest on any Note (which may only be waived with the consent of each Holder of Notes
affected). 
 Section 6.05 Control by Majority. 

Subject to the terms of the Intercreditor Agreement, the Security Documents and certain restrictions, the Holders of a majority in
principal amount of the then-outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Collateral Agent. However, the Trustee and the Collateral
Agent may refuse to follow any direction that conflicts with law, the Intercreditor Agreement, any other Security Document or this Indenture, that may involve the Trustee’s or the Collateral Agent’s personal liability, or that the Trustee
or the Collateral Agent determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction
received from Holders of Notes.

 Section 6.06 Limitation on Suits. 

A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: (1) the Holder gives the Trustee written
notice of a continuing Event of Default; (2) the Holders of at least 25% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer the Trustee indemnity
reasonably satisfactory to the Trustee against any costs, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and (5) during such 60-day period, the
Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 
 Notwithstanding the foregoing, in no event may any Holder enforce any Lien of the Collateral Agent pursuant to the Security Documents. 

Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if
any, and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer pursuant to Section 4.07 or a Change of Control Offer), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.08 Collection Suit by Trustee. 
 If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium, if any, and
Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and 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, its agents and counsel. 
 Section 6.09
Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or
remedy under this Indenture 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 proceedings or
any other proceedings, the Issuers, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies hereunder of the Trustee and the Holders shall continue as though
no such proceeding has been instituted. 
 Section 6.10 Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in
Section 2.07, 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. 

  
 -79-









 Section 6.11 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 6.12 Trustee May File
Proofs of Claim. 
 Subject to the Intercreditor Agreement, the Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the
Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes including the Guarantors), their creditors or their property and shall be entitled and empowered to participate as a member in any official
committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding. 
 Section 6.13 Priorities.

the Collateral Agent), it shall pay out the money in the following order:

Interest, if any, and interest, respectively; and 
 (iii) to the Issuers or to such party as a court of
competent jurisdiction shall direct, including a Guarantor, if applicable.

pursuant to this Section 6.13. 
 Section 6.14 Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.14 does not apply to a suit by the Trustee, a suit by

Section 7.01 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its
exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default: 

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need

correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein).

to examine the books, records and premises of the Issuers, personally or by agent or attorney at the sole cost of the Issuers and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The
Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent or
attorney appointed with due care.

(g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture. 

(h) 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. 

  
 -82-









 (i) 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.

Issuers’ obligation to pay Additional Interest no later than 15 days prior to the next Interest Payment Date, which notice shall set forth the amount of the Additional Interest to be paid by the Issuers. The Trustee shall not at any time

directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Trustee shall have received an incumbency certificate listing persons designated
to give such instructions or directions and containing specimen signatures of such designated persons. Such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Issuers elect to
give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed
controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or inconsistency
with a subsequent written instruction. The Issuers agree to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including the risk of the Trustee acting on unauthorized
instructions, and the risk or interception and misuse by third parties.

Trustee.

 Section 7.05 Notice of Defaults.

 If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice
of the Default within 90 days after it occurs. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so
long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. The Trustee shall not be deemed to know of any Default unless a Responsible Officer of the Trustee
has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee at the Corporate Trust Office of the Trustee. 
 Section 7.06 Reports by Trustee to Holders of the Notes. 
 Within
60 days after each November 15, beginning with the November 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such

and severally, shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and counsel.

hold the Trustee harmless against, any and all loss, damage, claims, liability or expense (including attorneys’ fees and expenses) incurred by it in connection with the acceptance or administration of this trust and the performance of its
duties hereunder (including the costs and expenses of enforcing this Indenture against the Issuers or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, the Issuers or any
Guarantor, or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder). The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Issuers shall not relieve the Issuers of its obligations hereunder. The Issuers and the Guarantors need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own
willful misconduct or gross negligence. 
 The obligations of the Issuers under this Section 7.07 shall survive the
satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or Section 6.01(9) occurs, the expenses and the compensation for the services
(including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Code. 
 The Trustee shall comply with the provisions of Trust Indenture Act Section 313(b)(2) to the extent applicable. As used in this Section 7.07, the term “Trustee” shall also include each
of the Paying Agent, Registrar, and Transfer Agent, as applicable.

retiring Trustee (at the Issuers’ expense), the Issuers or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

payment of the retiring Trustee’s fees and expenses (including the fees and expenses of its agents and counsel), the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided
all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07
shall continue for the benefit of the retiring Trustee.

federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such
Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 

(3) in the case of Covenant Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same

breach or violation of, or constitute a default under, any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 

(6) the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that, assuming no intervening
bankruptcy of any Issuers or any Guarantor between the date of deposit and the 91st day following the deposit and assuming that no Holder is an “insider” of any Issuer under applicable bankruptcy law, after the 91st day 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, including Section 547 of the United States Bankruptcy Code and
Section 15 of the New York Debtor and Creditor Law; 
 (7) the Issuers shall have delivered to the Trustee
an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding creditors of the

qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 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 Issuers or a Guarantor acting as Paying Agent), to the Holders of such Notes of all sums due and to become due thereon in respect
of principal, premium and Additional Interest, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 8.04 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 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon the written request of the Issuers any money or Government
Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered
under Section 8.04(2)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 Section 8.06 Repayment to the Issuers. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of,
premium and Additional Interest, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium and Additional Interest, if any, or interest has become due and payable shall be paid to the Issuers on their
request or (if then held by the Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuers as trustee thereof, shall thereupon cease. 
 Section 8.07 Reinstatement.

 If the Trustee or Paying Agent is unable to apply any U.S. dollars or Government Securities in accordance with
Section 8.04 or 8.05, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under this Indenture and
the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.04 or 8.05 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.04 or 8.05, as
the case may be; provided that, if the Issuers make any payment of principal of, premium and Additional Interest, if any, or interest on any Note following the reinstatement of their obligations, the Issuers shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

waiver, the Trustee shall receive and (subject to Section 7.01) shall be fully protected in conclusively relying upon, in addition to the documents required by Section 15.04, an Officers’ Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuers and any Guarantors party thereto,
enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, no Opinion of Counsel will be required for the Trustee to
execute any amendment or supplement adding a new Guarantor under this Indenture. 
 It shall not be necessary for the consent of

affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental
indenture or waiver.

GUARANTEES 

This Article 13 shall only be applicable after the date of the Assumption 

Section 13.01 Guarantee. 
 Subject to this Article 13, each of the Guarantors hereby, jointly and severally, guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors
and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that: (a) the principal of, interest, premium and Additional Interest, if any, on the Notes
shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or
the Trustee hereunder or thereunder shall be promptly 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 any of such other obligations,
that same shall be promptly 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. Failing payment when due of any amount so guaranteed or any
performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture. 

  
 -94-









 Each Guarantor also agrees to pay any and all costs and expenses (including reasonable
attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 13.01. 

If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and
effect. 
 Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect
of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors
for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantees. 

Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the
Issuers for liquidation or reorganization, should the Issuers become 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 Issuers’ 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 or Note Guarantees, 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. 

In case any provision of any Note 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. 
 Each payment to be made by a Guarantor in respect
of its Note Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 As used in
this Section 13.01, the term “Trustee” shall also include each of the Paying Agent, Registrar and Transfer Agent, as applicable.

 Section 13.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect
to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any
other Guarantor in respect of the obligations of such other Guarantor under this Article 13, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable
law. Each Guarantor that makes a payment under its Note Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s
pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP. 
 Section 13.03 [RESERVED]. 
 Section 13.04 Subrogation.

 Each Guarantor shall be subrogated to all rights of Holders of Notes against the Issuers in respect of any amounts paid by
any Guarantor pursuant to the provisions of Section 13.01; provided that, if an Event of Default has occurred and is continuing, no 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 Issuers under this Indenture or the Notes shall have been paid in full. 
 Section 13.05 Benefits Acknowledged. 
 Each Guarantor acknowledges
that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Note Guarantee are knowingly made in contemplation of such benefits.

 Section 13.06 Release of Guarantees. 
 A Note Guarantee of a Guarantor will be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect): 

(1) in connection with any sale or other disposition (including by merger or otherwise) of Capital Stock of the Guarantor
after which such Guarantor is no longer a Subsidiary of the Company, if the sale of all such Capital Stock of that Guarantor complies with the applicable provisions of this Indenture; 

(2) if the Company properly designates the Guarantor as an Unrestricted Subsidiary under this Indenture; 

(3) solely in the case of a Note Guarantee created pursuant to Section 4.08(b). upon the release or discharge of the
Guarantee that resulted in the creation of such Note Guarantee pursuant to that covenant, except a discharge or release by or as a result of payment under such Note Guarantee;

that complies with the provisions under Section 8.02, 8.03 or Section 14.01, respectively; or 
 (5)
upon payment in full of the aggregate principal amount of all Notes then outstanding and all other obligations under this Indenture and the Notes then due and owing. 
 Upon any occurrence giving rise to a release of a Note Guarantee as specified above, the Trustee will, at the written direction of the Company, execute any documents reasonably required in order to
evidence or effect such release, termination and discharge in respect of such Note Guarantee. Neither the Company nor any Guarantor will be required to make a notation on the Notes to reflect any Note Guarantee or any such release, termination or
discharge. Upon any release of a Guarantor from its Note Guarantee, such Guarantor shall also be released from its obligations under the Security Documents.

 SATISFACTION AND DISCHARGE 

Section 14.01 Satisfaction and Discharge. 
 This Indenture shall be discharged and shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Notes as is herein expressly provided) as to
all Notes issued hereunder, when: 
 (1) either: 

(a) all Notes that have been authenticated (except lost, stolen or destroyed Notes that have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuers) have been delivered to the Trustee for cancellation; or 

(b) all Notes that have not been delivered to the Trustee for cancellation (x) have become due and payable (by
reason of the mailing of a notice of redemption or otherwise), (y) will become due and payable at Stated Maturity within one year, or (z) are to be called for redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the Issuers’ names and at the Issuer’s expense, and in each such case the Issuers have 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 Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, without
consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Additional Interest, if any, and accrued interest to the Stated
Maturity or redemption date, as the case may be; 
 (2) no Default or Event of Default will have occurred and be
continuing on the date of such deposit or will occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which any Issuer or any Guarantor is a party or by
which any Issuer or any Guarantor is bound;

 Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee
pursuant to clause (1)(b) of this Section 14.01, the provisions of Section 14.02 and Section 8.06 shall survive. 
 Section 14.02 Application of Trust Money. 
 Subject to the provisions
of Section 8.06, all money or Government Securities deposited with the Trustee pursuant to Section 14.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either
directly or through any Paying Agent (including the Issuers acting as their own Paying Agent), to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money has been
deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. 
 If
the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 14.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 14.01;
provided that if the Issuers have made any payment of principal of, premium and Additional Interest, if any, or interest on any Notes because of the reinstatement of their obligations, the Issuers shall be subrogated to the rights of the

amount of the Notes, plus a special redemption fee of 1% of the aggregate principal amount of the Senior Secured Notes and the interest payable on the Notes to July 30, 2012. Funds held in the Escrow Account will be released in accordance with
the conditions set forth in the Escrow Agreement (the “Release Date”). If the Release Date does not occur on or prior to three Business Days prior to July 30, 2012 (or as such date may be extended from time to time pursuant to
the Escrow Agreement up to December 18, 2012),or if certain other events specified under the Escrow Agreement occur, the Issuer shall cause a notice of a special mandatory redemption to be delivered to DTC in accordance with the terms of the
Indenture. If such notice is delivered, subject to the terms of the Indenture, the amounts in the Escrow Account shall be used by the Issuer to redeem the Notes at a price equal to the principal amount of the Notes outstanding and a special

described in Section 6 above, the redemption notice may be mailed less than 30 days prior to the Redemption Date. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless
all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption. 
 8. OFFERS TO REPURCHASE. 
 (a) If a Change of Control occurs, each Holder of Notes
will have the right to require the Issuer to purchase all or any part (in integral multiples of $1,000 except that no purchase will be permitted that would result in a Note having a remaining principal amount of less than $2,000) of such
Holder’s Notes pursuant to a Change of Control offer. In the Change of Control offer, the Issuers will offer to purchase all of the Notes, at a purchase price in cash in an amount equal to 101% of the principal amount of such Notes, plus

any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, Additional Interest, if any, or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its
consequences under the Indenture except a continuing Default in payment of the principal of, premium, if any, Additional Interest, if any, or interest on, any of the Notes held by a non-consenting Holder. The Issuers and each Guarantor (to the
