(5)    licenses and sublicenses by the Company or any of its Restricted Subsidiaries of software or intellectual property in the ordinary course of business;
(6)    any surrender or waiver of contract rights or settlement, release, recovery on or surrender of contract, tort or other claims in the ordinary course of business;

“Attributable Debt” in respect of a sale and leaseback transaction means, at the time of determination, the present value of the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale and leaseback transaction including any period for which such lease has been extended or may, at the option of the lessor, be extended. Such present value shall be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with GAAP; provided, however, that if such sale and leaseback transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby shall be determined in accordance with the definition of “Capital Lease Obligation.”
“Bankruptcy Law” means Title 11 of the United States Code, as amended, or any similar federal or state law for the relief of debtors.
“Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” shall be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning.
“Board of Directors” means:
(1)    with respect to a corporation, the board of directors of the corporation or any committee thereof duly authorized to act on behalf of such board;
(2)    with respect to a partnership, the Board of Directors of the general partner of the partnership;

“Broker-Dealer” means any broker or dealer, in either case, that is registered under the Exchange Act.
“Business Day” means any day other than a Legal Holiday.
“Capital Lease Obligation” means, at the time any determination is to be made, the amount of the liability in respect of a capital lease that would at that time be required to be capitalized on a balance sheet prepared in accordance with GAAP, and the Stated Maturity thereof shall be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such lease may be prepaid by the lessee without payment of a penalty. Notwithstanding the foregoing, any lease (whether entered into before or after the date of this Indenture) that would have been classified as an operating lease pursuant to GAAP as in effect on the date of this Indenture shall be deemed not to represent a Capital Lease Obligation.
“Capital Stock” means:
(1)    in the case of a corporation, corporate stock;
(2)    in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock;

(4)    any other interest or participation that confers on a Person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing Person, but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such debt securities include any right of participation with Capital Stock.
“Cash Equivalents” means:
(1)    United States dollars;
(2)    securities issued or directly and fully guaranteed or insured by the United States government or any agency or instrumentality of the United States government (provided that the full faith and credit of the United States is pledged in support of those securities) having maturities of not more than six months from the date of acquisition;
(3)    certificates of deposit and eurodollar time deposits with maturities of six months or less from the date of acquisition, bankers’ acceptances with maturities not exceeding six months and overnight bank deposits, in each case, with any lender party to the Credit Agreement or with any domestic commercial bank having capital and surplus in excess of $500.0 million and a Thomson Bank Watch Rating of “B” or better;

(6)    money market funds at least 95% of the assets of which constitute Cash Equivalents of the kinds described in clauses (1) through (5) of this definition;

(11)    any evidence of Indebtedness (including variable rate demand notes), maturing not more than one year after such time, issued by any State of the United States, by any county or municipality organized or incorporated under the laws of any State of the United States or by any agency or subdivision of any of the foregoing, in each case rated “A−” or better by S&P or rated “A3” or better by Moody’s;

(13)    any mutual funds or similar investment vehicles investing primarily in Investments of the types set forth in the foregoing clauses (1) through (12), provided that ratings requirements shall be applicable to the mutual fund rather than the underlying Investments, as follows: such mutual funds shall, in each case, have a rating of “A−” or better from S&P or a rating of “A3” from Moody’s, provided, however, that it is agreed that (i) any Investment which when made complies with the requirements of any of the foregoing clauses (7), (8), (9), (10), (11) or (12) may continue to be held notwithstanding that such Investment if made thereafter would not comply with such requirements; and (ii) no Investment otherwise permitted by clauses (12) or (13) shall be permitted to be made directly or indirectly through a mutual fund if, immediately before or after giving effect thereto, any Default shall have occurred and be continuing; and

The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

Section 2.02    Execution and Authentication.
At least one Officer must sign the Notes for the Company by manual or facsimile signature.
If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.
A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.
The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate (i) Initial Notes for original issue in an aggregate principal amount of $120,569,000, and (ii) if issued, any Additional Notes in an aggregate principal amount not to exceed the amount permitted by Section 4.09(b)(iii).

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium on, if any, or interest on, the Notes, and will notify the Trustee, in writing, of any default by the Company 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 Company 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 the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. If the Company or a Subsidiary acts as Paying Agent, upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.
Section 2.05    Holder Lists.
The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA §312(a).

(h)    Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for beneficial interests in another Global Note or Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(iv)    All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.
(v)    Neither the Trustee, the Registrar nor the Company will be required:

(x)    The Trustee shall have no responsibility or obligation to any Participant or Indirect Participant or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Participant or Indirect Participant or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Note).

Section 2.07    Replacement Notes.
If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, security or an indemnity satisfactory to the Trustee or the Company, as applicable, must be supplied by the Holder to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Holder must also provide the Trustee any other documents (including a lost note affidavit) that the Trustee may request.  The Company may charge for its expenses in replacing a Note.
If, after delivery of such new Note, a protected purchaser of the predecessor Note  presents for payment, transfer or exchange such replaced Note, the Company, the Trustee, any Agent and any authenticating agent shall be entitled to recover such new Note from the Person to whom it was delivered or any Person taking therefrom, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee, any Agent and any authenticating agent in connection therewith.
Every replacement Note is an additional obligation of the Company and will 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 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.
If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.
If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.
If the Paying Agent (other than the Company, 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 will be deemed to be no longer outstanding and will 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 Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee receives an Officers’ Certificate from the Company that such Notes are so owned will be so disregarded. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and the Trustee shall be entitled to accept and rely upon such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any determination.
Section 2.10    Temporary Notes.
Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company will prepare and the Trustee will, upon receipt of an Authentication Order, authenticate definitive Notes in exchange for temporary Notes.
Holders of temporary Notes will be entitled to all of the benefits of this Indenture.
Section 2.11    Cancellation.
The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes in its customary manner. Certification of the destruction of all canceled Notes will be delivered to the Company upon its written request therefor. The Company 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 Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will 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. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

The Company will promptly notify the Trustee in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.
Section 3.03    Notice of Redemption.
Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company will send or cause to be sent, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 hereof. Notice of any redemption, including, without limitation, upon an Equity Offering, may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.
The notice will identify the Notes to be redeemed and will state:
(i)    the redemption date;
(ii)    the redemption price;
(iii)    if any Note is being redeemed in part, the portion of the principal amount of such Note 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 will be issued upon cancellation of the original Note;
(iv)    the name and address of the Paying Agent for purposes of the redemption;
(v)    that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;
(vi)    that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;
(vii)    the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and
(viii)    that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.
At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.
Section 3.04    Effect of Notice of Redemption.
Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become due and payable on the redemption date at the redemption price, unless the redemption is subject to a condition precedent that is not satisfied or waived.
Section 3.05    Deposit of Redemption or Purchase Price.
At least one Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, and accrued interest on all Notes to be redeemed or purchased on that date and to pay any amounts owing to the Trustee and the Collateral Agent. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, accrued interest on all Notes to be redeemed or purchased and to pay any amounts owing to the Trustee and the Collateral Agent.
If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or accepted for purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest 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 is not so paid upon surrender for redemption or tendered for purchase because of the failure of the Company 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 not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.
Section 3.06    Notes Redeemed or Purchased in Part.

Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.
(d)    Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.
Section 3.08    Mandatory Redemption.
Except as set forth below under Sections 4.10 and 4.14 hereof, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of Holders of the Notes.
Section 3.09    Offer to Purchase by Application of Excess Proceeds.
In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified below.
The Asset Sale Offer shall be made to all Holders and all holders of Second Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets. The Asset Sale Offer shall remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Second Lien Debt (on a pro rata basis based on the principal amount of Notes and such other Second Lien Debt surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Second Lien Debt tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.
If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.
Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:
(iv)    that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;
(v)    the Offer Amount, the purchase price and the Purchase Date;
(vi)    that any Note not tendered or accepted for payment will continue to accrue interest;
(vii)    that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;
(viii)    that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;
(ix)    that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;
(x)    that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;
(xi)    that, if the aggregate principal amount of Notes and other Second Lien Debt surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other Second Lien Debt to be purchased on a pro rata basis based on the principal amount of Notes and such other Second Lien Debt surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and
(xii)    that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).
On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.
Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

The Company will not take any action for the purpose of causing the SEC not to accept any such filings.

(d)     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 Officers’ Certificates).


Section 4.04    Compliance Certificate.
(j)    The Company and each Guarantor (to the extent that such Guarantor is so required under the TIA) shall deliver to the Trustee, within 90 days after the end of each fiscal year (beginning with the fiscal year ending on December 31, 2016), an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture and the Security Documents, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and the Security Documents and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture or the Security Documents (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, premium on, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

Section 4.05    Taxes.
The Company will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.
Section 4.06    Stay, Extension and Usury Laws.
The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

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

(xi)    Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;
(xii)    Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;
(xiii)    provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements;
(xiv)    restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;
(xv)    any agreement or instrument relating to any property or assets acquired after the date of this Indenture, so long as such encumbrance or restriction relates only to the property or assets so acquired (plus improvements and accessions to, such property or proceeds or distributions thereof) and is not and was not created in anticipation of such acquisition; and
(xvi)    existing under, by reason of or with respect to provisions with respect to any Indebtedness incurred by a Restricted Subsidiary in compliance with Section 4.09 hereof, or any agreement pursuant to which such Indebtedness is issued, if the encumbrance or restriction is not materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined by the Board of Directors of the Company) and the Board of Directors of the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to pay interest or principal on the Notes.
Section 4.09    Incurrence of Indebtedness and Issuance of Preferred Stock.
(a)    The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.
(b)    The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):
(xvii)    the incurrence by the Company and any Guarantor of additional Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (i) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and any Guarantor thereunder) not to exceed $100.0 million less (x) the amount of Indebtedness incurred by Foreign Subsidiaries outstanding under clause (xxi) below, and (y) the amount of Indebtedness outstanding under clause (xix) below except to the extent subject to a Lien permitted by item (25) of the definition of “Permitted Liens,” and (z) the amount of Indebtedness outstanding under clause (xx) below;

(xx)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations (other than Deemed Capitalized Leases), mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries (whether through (a) the direct purchase of such assets or (b) the purchase of the Capital Stock of a Person owning such assets (but no other material assets) the result of which is that such Person becomes a Subsidiary of the Company or another Restricted Subsidiary) and related financing costs, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (iv), not to exceed $25.0 million at any time outstanding, and in each case at arms-length and on market terms (as determined by an Officer of the Company in such Officer’s reasonable discretion);
(xxi)    the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (ii), (iii), (iv), (v) or (xii) of this Section 4.09(b);
(xxii)    the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:
(A)    if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Guarantor; and

(xxiii)    the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that:
(A)    any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and
(B)    any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (vii);

(xxvi)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations and bankers’ acceptances in the ordinary course of business;
(xxvii)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

(xxxiii)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety, appeal, reimbursement and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company or any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case other than an obligation for borrowed money);
(xxxiv)    [Intentionally Omitted];
(xxxv)    letters of credit and/or bank guarantees issued in the ordinary course of business by a financial institution other than a lender or Affiliate of a lender under the Credit Agreement if the Company has reasonably determined that neither such lender or Affiliate is able to issue such letter of credit or bank guaranty, up to a maximum total for all such letters of credit at any one time outstanding of the lesser of (x) $10.0 million and (y) the difference between $110.0 million and the amount incurred and outstanding under clauses (i) and (xix) of this Section 4.09(b); 
(xxxvi)    the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness (excluding Priority Lien Debt and Indebtedness of the type described in clause (b)(iii)) or the issuance by the Company of additional Disqualified Stock in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (xx), not to exceed of the lesser of (x) $25.0 million and (y) the difference between $125.0 million and the amount incurred and outstanding under clauses (i) and (xx) of this Section 4.09(b);

(xxxviii)    the incurrence of Indebtedness secured on a pari passu or junior priority basis to the Notes, in an aggregate principal amount outstanding equal to the amount of Notes redeemed on or prior to the date of such incurrence.
Notwithstanding anything herein to the contrary, any Senior Indebtedness incurred to refinance, replace, defease or refund the Third Lien Notes after the date hereof shall have (i) except in the case of Additional Notes (which may have the same Stated Maturity date as the Notes), a maturity date at least 90 days after the Stated Maturity date of the Notes and (ii) a face amount not to exceed 55% of the face amount of such Third Lien Notes being refinanced, replaced, defeased or refunded. 
For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in Section 4.09(b)(i) through Section 4.09(b)(xxii) above, or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes are first issued and authenticated under this Indenture will be deemed to have been incurred on such date in reliance on the exception provided by Section 4.09(b)(i). The accrual of interest or preferred stock dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. 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 utilized, calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.
The amount of any Indebtedness outstanding as of any date will be:
		
	(1)
	the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;


		
	(2)
	the principal amount of the Indebtedness, in the case of any other Indebtedness; and


		
	(3)
	in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:


		
	(a)
	the Fair Market Value of such assets at the date of determination; and


		
	(b)
	the amount of the Indebtedness of the other Person. 


Section 4.10    Asset Sales.
(a)    The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:
(xxxix)    the Company or any of its Restricted Subsidiaries (as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and
(xl)    at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiaries (measured as of the date of the definitive agreement with respect to such Asset Sale) and all other Asset Sales since May 13, 2013 is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:
(A)    any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are forgiven or assumed by the transferee of any such assets pursuant to a customary novation or indemnity agreement that releases the Company or such Restricted Subsidiary or indemnifies against further liability;
(B)    any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;
(C)    any stock or assets of the kind referred to in Section 4.10(b)(ii) or (iv) hereof;
(D)    accounts receivable of a business retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale of such business, provided that such accounts receivable do not have a payment date greater than 90 days from the date of the invoices creating such accounts receivable and are not past due; and
(E)    Indebtedness (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or a Note Guarantee) of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale; provided that the Company and each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale;
provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of Sections 4.10(a)(i) and 4.10(a)(ii) above. Notwithstanding the preceding, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portions of the consideration received therefrom, determined in accordance with the preceding provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.
(b)    Within 365 days after the receipt of any Net Proceeds from an Asset Sale, other than a Sale of Collateral, the Company or one or more of its Restricted Subsidiaries may at its option apply cash in an amount equal to the amount of such Net Proceeds to any combination of the following:
(i)    to repay (or cash collateralize) (A) Priority Lien Obligations and, (B) to the extent required by the documents governing such Indebtedness, Indebtedness permitted to be incurred pursuant to Section 4.09(b)(iv) hereof, provided that such Indebtedness was incurred for the purpose of financing all or part of the purchase price or cost of the design, construction, installation or improvement of such assets;
(ii)    to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company;
(iii)    to make capital expenditures in the Permitted Business, including investments in multi-client data libraries; or
(iv)    to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.
The requirement of clause (ii) or (iv) of this Section 4.10(b) shall be deemed to be satisfied if a bona fide binding contract committing to make the investment referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within 180 days following the date such agreement is entered into. Pending the final application of any Net Proceeds, the Company (or any Restricted Subsidiary) may invest the Net Proceeds in any manner that is not prohibited by this Indenture.
(c)    Within 365 days after the receipt of any Net Proceeds from an Asset Sale that constitutes a Sale of Collateral, the Company (or the Restricted Subsidiary that owned those assets, as the case may be) may at its option apply cash in an amount equal to the amount of such Net Proceeds to any combination of the following: (1) to purchase or invest in other long-term assets that would constitute Collateral; (2) to repay (or cash collateralize) Priority Lien Obligations or (3) to make capital expenditures in the Permitted Business, including investments in multi-client data libraries in each case, comprising Collateral.
(d)    Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $15.0 million, within five days thereof, the Company will, to the extent permitted by the Intercreditor Agreement, make an Asset Sale Offer to all Holders of Notes and all holders of Second Lien Debt containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase, prepay or redeem the maximum principal amount of Notes and such other Second Lien Debt (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture.  If the aggregate principal amount of Notes and other Second Lien Debt tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes and such other Second Lien Debt to be purchased on a pro rata basis (except that any Notes represented by a note in global form will be selected by such method as DTC or its nominee or successor may require or a method that most nearly approximates pro rata selection unless otherwise required by law), based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.
(e)    The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 hereof or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance.
Section 4.11    Transactions with Affiliates.
(a)    The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $1.0 million, unless:
(v)    the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and
(vi)    the Company delivers to the Trustee:
(D)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this covenant; and
(E)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliated Transactions complies with this covenant and that such Affiliate Transaction or series of related Affiliated Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company.
(b)    The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:
(xii)    any employment agreement or arrangement, equity award, equity option or equity appreciation agreement or plan, employee benefit plan, officer or director indemnification agreement, severance agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances pursuant thereto;
(xiii)    transactions between or among the Company and/or its Restricted Subsidiaries (or an entity that becomes a Restricted Subsidiary as a result of such transactions);
(xiv)    transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;
(xv)    payment of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries;
(xvi)    any issuance, dividend or distribution of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of capital contributions from, Affiliates of the Company and the granting of registration rights and other customary rights in connection therewith;
(xvii)    Permitted Investments and Restricted Payments that do not violate Section 4.07 hereof;
(xviii)    payments to an Affiliate in respect of the Notes or any other Indebtedness of the Company or any Restricted Subsidiary on the same basis as concurrent payments made or offered to be made in respect thereof to non-Affiliates;
(xix)    any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal, advisory or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(i);
(xx)    loans or advances to employees in the ordinary course of business not to exceed $5.0 million in the aggregate at any one time outstanding;
(xxi)    transactions with Unrestricted Subsidiaries, joint ventures, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board of Directors or any Officer of the Company involved in or otherwise familiar with such transaction, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;
(xxii)    transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person;
(xxiii)    the existence of, and the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of, any written agreement to which the Company or any of its Restricted Subsidiaries is a party on the date of this Indenture, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any amendment, modification or supplement entered into after the date of this Indenture will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to the Holders of the Notes than the terms of the agreements in effect on the date of this Indenture (as conclusively evidenced by a resolution of the Board of Directors of the Company);
(xxiv)    transactions entered into by a Person prior to the time such Person becomes a Restricted Subsidiary or is merged or consolidated into the Company or a Restricted Subsidiary (provided that such transaction is not entered into in contemplation of such merger or consolidation);
(xxv)    dividends and distributions to the Company and its Restricted Subsidiaries by any Unrestricted Subsidiary or joint venture;
(xxvi)    any transaction where the only consideration paid by the Company or Restricted Subsidiary is Equity Interests of the Company (other than Disqualified Stock); and

Section 4.12    Liens.
The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness, Attributable Debt or trade payables on any asset now owned or hereafter acquired, except Permitted Liens.
Section 4.13    Corporate Existence.
Subject to Article 5 and Section 11.04 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect:
(i)    its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and
(ii)    the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.
Section 4.14    Offer to Repurchase Upon Change of Control.
(a)    Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within ten days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:
(i)    that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;
(ii)    the purchase price and the purchase date, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);
(iii)    that any Note not tendered will continue to accrue interest;
(iv)    that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;
(v)    that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;
(vi)    that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and
(vii)    that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.
The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.
(b)    Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company will, on the Change of Control Payment Date:
(i)    deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and
(ii)    deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.
The Paying Agent will promptly mail (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all of the Notes are then in global form, make such payment through the facilities of DTC), and the Trustee will, upon receipt of an Authentication Order, promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.
(c)    Notwithstanding anything to the contrary in this Section 4.14, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption has been given pursuant to Section 3.07 hereof, and all conditions precedent to such redemption have been satisfied or waived, unless and until there is a default in payment of the applicable redemption price or (3) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made.
(d)    Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made.
(e)    In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or any third party making such Change of Control Offer or Alternate Offer in lieu of the Company) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice to the Trustee and the Holders, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate Offer, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date). Any redemption pursuant to this Section 4.14(e) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.
Section 4.15    Additional Note Guarantees.
If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary (other than an Immaterial Subsidiary) or any other Restricted Subsidiary guarantees Indebtedness of the Company or any Domestic Subsidiary in excess of a De Minimis Guaranteed Amount, then such Subsidiary will become a Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel regarding the due authorization, execution and delivery of the related supplemental indenture and enforceability of the obligations of the Restricted Subsidiary as a Guarantor, within 30 business days of the date on which it was acquired or created or on which it Guaranteed such Indebtedness. The form of such supplemental indenture is attached as Exhibit F hereto.
Section 4.16    Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be either an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 hereof or represent a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.
Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. In the case of any designation by the Company of a Person as an Unrestricted Subsidiary on the first day that such Person is a Subsidiary of the Company in accordance with the provisions of this Indenture, such designation shall be deemed to have occurred for all purposes of this Indenture simultaneously with, and automatically upon, such Person becoming a Subsidiary. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (a) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period; and (b) no Default or Event of Default would be in existence following such designation.
Section 4.17    Covenant Suspension.
(a)    If on any date following the date of this Indenture (i) the Notes are rated Baa3 or better by Moody’s and BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Company, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” registered under Section 15E of the Exchange Act selected by the Company as a replacement agency) (“Investment Grade”) and (ii) no Default or Event of Default shall have occurred and be continuing (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), then, beginning on that day and subject to the provisions of the following paragraph, Sections 4.07, 4.08, 4.09, 4.10 (provided that those provisions relating to the Sale of Collateral and the application of the proceeds therefrom shall remain in full force and effect and shall not be suspended), 4.11, 4.16 and 5.01(iv)(A) hereof shall be suspended (collectively, the “Suspended Covenants”).
(b)    During any period that the Suspended Covenants have been suspended as a result of a Covenant Suspension Event, the Company’s Board of Directors may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.16 hereof or the second paragraph of the definition of Unrestricted Subsidiary.
(c)    Notwithstanding the foregoing, if on any subsequent date, the Notes cease to maintain Investment Grade ratings, the Suspended Covenants will be reinstituted as of and from the date of such rating decline (a “Reversion Date”). Calculations under the reinstated Section 4.07 will be made as if Section 4.07 had been in effect since the date of this Indenture except that no default will be deemed to have occurred solely by reason of a Restricted Payment made while Section 4.07 was suspended.
(d)    Upon the occurrence of a Covenant Suspension Event or a Reversion Date, the Company shall provide written notice to the Trustee, the Collateral Agent and the Holders, and file with the Trustee an Officers’ Certificate certifying that such suspension or reversion complied with the foregoing provisions.
(e)    The Trustee shall not be responsible or liable for monitoring the ratings of the Notes or otherwise confirming whether any covenants are suspended or reinstituted pursuant to the above.
Section 4.18    Further Assurances; Insurance.
(a)    The Company and each of the other Guarantors shall do or cause to be done all acts and things that may be necessary or desirable, or that the Collateral Agent, acting in accordance with the Intercreditor Agreement, from time to time may reasonably request, to assure and confirm that the Collateral Agent holds, for the benefit of the Second Lien Secured Parties, duly created and enforceable and perfected Second Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral after the Notes are issued), in each case, as contemplated by, and with the Lien priority required under, the Second Lien Documents.
(b)    If necessary or desirable or upon the request of the Collateral Agent or any Second Lien Representative, acting in accordance with the Intercreditor Agreement, at any time and from time to time, the Company and each of the other Guarantors shall promptly execute, acknowledge and deliver such security documents, instruments, certificates, notices and other documents, and take such other actions as shall be reasonably necessary or desirable to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Second Lien Documents for the benefit of the holders of Second Lien Obligations.
(c)    The Company and the other Guarantors will:
(i)    keep their properties adequately insured at all times by financially sound and reputable insurers;
(ii)    maintain such other insurance, to such extent and against such risks (and with such deductibles, retentions and exclusions), including fire and other risks insured against by extended coverage and coverage for acts of terrorism, as is customary with companies in the same or similar businesses operating in the same or similar locations, including public liability insurance against claims for personal injury or death or property damage occurring upon, in, about or in connection with the use of any properties owned, occupied or controlled by them;
(iii)    maintain such other insurance as may be required by law; and
(iv)    maintain such other insurance as may be required by the Security Documents.
(d)    Upon the request of the Collateral Agent, the Company and the other Guarantors shall furnish to the Collateral Agent full information as to their property and liability insurance carriers, certified as true and correct. Holders of Second Lien Obligations, as a class, shall be named as additional insureds, with a waiver of subrogation, on all insurance policies of the Company and the other Guarantors covering the Collateral and the Collateral Agent shall be named as loss payee, with 30 days’ notice of cancellation or material change, on all property and casualty insurance policies of the Company and the other Guarantors covering the Collateral.
Section 4.19    Impairment of Security Interest.
Except as permitted by the Intercreditor Agreement, the Company shall not, and shall not permit any of its Restricted Subsidiaries to, take or knowingly or negligently omit to take, any action which action or omission might or would have the result of materially impairing the security interest with respect to the Collateral for the benefit of the Trustee, the Collateral Agent and the other Second Lien Secured Parties, and the Company shall not, and shall not permit any of the Restricted Subsidiaries to, except as permitted under the terms of this Indenture, grant to any Person other than the Collateral Agent, for the benefit of itself, the Trustee and the other Second Lien Secured Parties and the other beneficiaries described in the Security Documents, any interest whatsoever in any of the Collateral.
Section 4.20    After-Acquired Property.
Promptly following the acquisition by the Company or any Guarantor of any After-Acquired Property, the Company or such Guarantor shall promptly execute and deliver such mortgages, deeds of trust, security instruments, financing statements and certificates and Opinions of Counsel as shall be reasonably necessary to vest in the Collateral Agent, for the benefit of the Second Lien Secured Parties, a perfected second priority security interest in such After-Acquired Property and to have such After-Acquired Property added to the Collateral and thereupon all provisions of the indenture relating to the Collateral shall be deemed to relate to such After-Acquired Property to the same extent and with the same force and effect.
Section 4.21    Limitation on Layered Indebtedness
Notwithstanding anything in this Indenture to the contrary, the Company shall not, and will not permit any Guarantor to incur any Indebtedness (including Permitted Debt) that is contractually subordinated either in right of payment or in respect of the grant or the application of proceeds of Collateral to any other Indebtedness of the Company or such Guarantor (including by way of “last out” tranches but excluding the customary waterfall payments among protective advances, swing line advances, advances and Hedging Obligations constituting the same tranche of Priority Lien Debt, such as those set forth in Section 11.5 of the Credit Agreement), unless such Indebtedness is also contractually subordinated in right of payment or in respect of the grant and the application of proceeds of Collateral, as the case may be, to the Notes and the applicable Guarantee on substantially identical terms. For the avoidance of doubt, the foregoing shall not prohibit any Permitted Refinancing of the Credit Agreement with other Priority Lien Debt.

(D)    is caused by a failure to pay principal of, premium on, if any, or interest, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or
(E)    results in the acceleration of such Indebtedness prior to its Stated Maturity,

(B)    except as permitted by this Indenture or the Intercreditor Agreement, any Second Lien purported to be granted under any security document on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $15.0 million ceases to be an enforceable and perfected second priority Lien, subject only to Permitted Prior Liens; or

(xiv)    except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee.
Section 6.02    Acceleration.
In the case of an Event of Default set forth in clause (viii) or (ix) of Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.
Upon any such declaration, the Notes shall become due and payable immediately.
The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal of, premium on, if any, or interest on the Notes that has become due solely because of the acceleration) have been cured or waived.
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 of, premium on, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.
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 a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.
Section 6.05    Control by Majority.
Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in liability or expense.
Section 6.06    Limitation on Suits.
Except to enforce the right to receive payment of principal, premium, if any, or interest, when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:
(xli)    such Holder has previously given the Trustee written notice that an Event of Default is continuing;
(xlii)    Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;
(xliii)    such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;
(xliv)    the Trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and
(xlv)    during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.
A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.
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 of, premium on, if any, or interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), 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; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.
Section 6.08    Collection Suit by Trustee and Collateral Agent.
If an Event of Default specified in Section 6.01(i) or (ii) hereof occurs and is continuing, the Trustee or the Collateral Agent is authorized to recover judgment (a) in its own name and (b)(i) in the case of the Trustee, as trustee of an express trust or (ii) in the case of the Collateral Agent, as collateral agent on behalf of the Holders, in each case against the Company for the whole amount of principal of, premium on, if any, and interest remaining unpaid on the Notes and, to the extent lawful, interest on overdue principal and 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, the Collateral Agent and their respective agents and counsel.
Section 6.09    Trustee May File Proofs of Claim.
The Trustee or the Collateral Agent 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 or the Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered 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 or the Collateral Agent, and in the event that the Trustee or the Collateral Agent shall consent to the making of such payments directly to the Holders, to pay to the Trustee or the Collateral Agent, as applicable, any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee or the Collateral Agent under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee or the Collateral Agent under Section 7.07 hereof 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 or the Collateral Agent 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 or the Collateral Agent to vote in respect of the claim of any Holder in any such proceeding.
Section 6.10    Priorities.
Subject to the Intercreditor Agreement, if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Collateral Agent, as the case may be, for any action taken or omitted by it as a Trustee or the Collateral Agent, 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, 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 6.11 does not apply to a suit by the Trustee or the Collateral Agent, as the case may be, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.
ARTICLE 7     
TRUSTEE
Section 7.01    Duties of Trustee.
(l)    If an Event of Default of which a Responsible Officer of the Trustee has actual knowledge or written notice has occurred and is continuing, the Trustee will 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.
(m)    Except during the continuance of an Event of Default of which a Responsible Officer of the Trustee has actual knowledge or written notice:
(i)    the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and
(ii)    the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will 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 any mathematical calculations or other facts stated therein).
(n)    The Trustee may not be relieved from liabilities for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, in each case as determined by a court of competent jurisdiction pursuant to a final and non-appealable decision, except that:
(i)    this paragraph does not limit the effect of paragraph (b) of this Section 7.01;
(ii)    the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved in a court of competent jurisdiction in a final and non-appealable decision that the Trustee was grossly negligent in ascertaining the pertinent facts; and
(iii)    the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it from the Company or a majority of Holders (or such other lower or greater amount required under the Note Documents) in accordance with the Note Documents.
(o)    Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to this Article 7.
(p)    No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.
(q)    The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.
Section 7.02    Rights of Trustee.
(a)    The Trustee may conclusively rely upon and shall be fully protected in acting upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document and may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein.
(b)    Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will 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. As to any fact or matter the manner of ascertainment of which is not specifically described herein, the Trustee shall be entitled to receive and may for all purposes hereof conclusively rely on a certificate, signed by an officer of any duly authorized Person, as to such fact or matter, and such certificate shall constitute full protection to the Trustee for any action taken or omitted to be taken by it in good faith in reliance thereon.  The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel will 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, custodian, nominees and agents and will not be responsible for the misconduct or negligence of, or for the supervision of, any attorneys, custodian, nominees or agent appointed with due care.
(d)    The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture or any other Note Document.
(e)    Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company.
(f)    The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture or any other Note Document at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.
(g)    The Trustee may request that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of Officers authorized at such time to take specified actions pursuant to the Note Documents and the Trustee shall be entitled to conclusively rely on such Officer’s Certificate until receipt of a superseding Officer’s Certificate.  
(h)    The Company shall provide prompt written notice to the Trustee of any change to its fiscal year (it being expressly understood that the failure to provide such notice to the Trustee shall not be deemed a Default or Event of Default under this Indenture).
(i)    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 of this Indenture.  For purposes of any determination as to whether a Responsible Officer of the Trustee shall be deemed to have actual knowledge of any of the foregoing events, the Trustee shall have no obligation to inquire into, or investigate as to, the occurrence of any such event.
(j)    The permissive or discretionary rights of the Trustee enumerated herein shall not be construed as duties.
(k)    The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.
(l)    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 (i) the Trustee in each of its capacities (including as an Agent) hereunder and under the Note Documents and (ii) the entity serving as the Trustee in each of its capacities hereunder and in each of its capacities as under any other Note Document or any related document whether or not specifically set forth therein, and each agent, custodian and other Person employed to act hereunder or thereunder.
(m)    The Trustee shall not be bound to make any investigation into (i) the performance or observance by the Company or any other Person of any of the covenants, agreements or other terms or conditions set forth in the Note Documents or in any related document, (ii) the occurrence of any default, or the validity, enforceability, effectiveness or genuineness of any Note Document, any related document or any other agreement, instrument or document, (iii) the creation, perfection or priority of any Lien purported to be created by this any Note Document or any related document, (iv) the value or the sufficiency of any Collateral or (v) the satisfaction of any condition set forth in any Note Document or any related document.
(n)    The Trustee shall not have any duty or responsibility in respect of (i) any recording, filing, or depositing of this Indenture, any other Note Document or any other agreement or instrument, monitoring or filing any financing statement or continuation statement evidencing a security interest, the maintenance of any such recording, filing or depositing or to any re-recording, re-filing or re-depositing of any thereof, or otherwise monitoring the perfection, continuation of perfection or the sufficiency or validity of any security interest in or related to the Collateral, (ii) the acquisition or maintenance of any insurance or (iii) the payment or discharge of any tax, assessment, or other governmental charge or any lien or encumbrance of any kind owing with respect to, assessed or levied against, any part of the Collateral.  The Trustee shall be authorized to, but shall in no event have any duty or responsibility to, file any financing or continuation statements or record any documents or instruments in any public office at any time or times or otherwise perfect or maintain any security interest in the Collateral.  
(o)    Each Holder, by its acceptance of a Note hereunder, represents that it has, independently and without reliance upon the Trustee or any other Person, and based on such documents and information as it has deemed appropriate, made its own investment decision in respect of the Notes.  Each Holder also represents that it will, independently and without reliance upon the Trustee or any other Person, and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under this Indenture and in connection with the Notes.  Except for notices, reports and other documents expressly required to be furnished to the Holders by the Trustee hereunder, the Trustee shall not have any duty or responsibility to provide any Holder with any other information concerning the Issuer, the servicer or any other parties to any related documents which may come into the possession of the Trustee or any of its officers, directors, employees, agents, representatives or attorneys-in-fact.
(p)    If the Trustee requests instructions from the Company or the Holders with respect to any action or omission in connection with any Note Document, the Trustee shall be entitled (without incurring any liability therefor) to refrain from taking such action and continue to refrain from acting unless and until the Trustee shall have received written instructions from the Company or the Holders, as applicable, with respect to such request.
(q)    In order to comply with laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering (“Applicable Law”), the Trustee is required to obtain, verify and record certain information relating to individuals and entities which maintain a business relationship with the Trustee.  Accordingly, each of the parties and each Holder agrees to provide to the Trustee upon its request from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee to comply with Applicable Law.
(r)    In no event shall the Trustee be liable for any failure or delay in the performance of its obligations under any Note Document or any related documents because of circumstances beyond the Trustee’s control, including, but not limited to, a failure, termination, or suspension of a clearing house, securities depositary, settlement system or central payment system in any applicable part of the world or acts of God, flood, war (whether declared or undeclared), civil or military disturbances or hostilities, nuclear or natural catastrophes, political unrest, explosion, severe weather or accident, earthquake, terrorism, fire, riot, labor disturbances, strikes or work stoppages for any reason, embargo, government action, including any laws, ordinances, regulations or the like (whether domestic, federal, state, county or municipal or foreign) which delay, restrict or prohibit the providing of the services contemplated by the Note Documents or any related documents, or the unavailability of communications or computer facilities, the failure of equipment or interruption of communications or computer facilities, or the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility, or any other causes beyond the Trustee’s control whether or not of the same class or kind as specified above.
(s)    The Trustee shall not be liable for failing to comply with its obligations under any Note Document in so far as the performance of such obligations is dependent upon the timely receipt of instructions and/or other information from any other person which are not received or not received by the time required.
(t)    The Trustee shall be fully justified in failing or refusing to take any action under any Note Document or any other related document if such action (A) would, in the reasonable opinion of the Trustee, in good faith (which may be based on the advice or opinion of counsel), be contrary to applicable law, any Note Document or any other related document, or (B) is not provided for in the Note Documents or any other related document.
(u)    The Trustee shall not be required to take any action under any Note Document or any related document if taking such action (A) would subject the Trustee to a tax in any jurisdiction where it is not then subject to a tax, or (B) would require the Trustee to qualify to do business in any jurisdiction where it is not then so qualified.
(v)    In no event shall the Trustee be liable for any special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.
Section 7.03    Individual Rights of Trustee.
The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.
Section 7.04    Trustee’s Disclaimer.
The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.
Section 7.05    Notice of Defaults.
If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall send to Holders of Notes, with a copy to the Collateral Agent, a notice of the Default or Event of Default within 90 days after it occurs or within 15 Business Days after it becomes actually known to a Responsible Officer of the Trustee, if later than 90 days after occurrence. Except in the case of a Default or Event of Default in payment of principal of, premium on, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders of the Notes.
Section 7.06    Reports by Trustee to Holders of the Notes.
(c)    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 will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA §313(a) (but if no event described in TIA §313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA §313(b)(2). The Trustee will also transmit by mail all reports as required by TIA §313(c).
(d)    A copy of each report at the time of its mailing to the Holders of Notes will be mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA §313(d). The Company will promptly notify the Trustee, in writing, when the Notes are listed on any stock exchange.
Section 7.07    Compensation and Indemnity.
(f)    The Company will pay to the Trustee and the Collateral Agent (and together with their respective officers, directors, employees, representatives, attorneys and agents, the “Indemnified Parties”, and each, an “Indemnified Party”) from time to time such compensation as agreed to in a separate fee agreement for its acceptance of this Indenture, the Security Documents and services hereunder and thereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse each Indemnified Party 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 will include, but are not limited to, costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders and the reasonable compensation, disbursements and expenses of each Indemnified Party’s agents and counsel.
(g)    The Company and the Guarantors will indemnify, defend and hold harmless, on a joint and several basis, each Indemnified Party against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture or the other Note Documents, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties under the Note Documents, except to the extent any such loss, liability or expense may be attributable to its gross negligence or willful misconduct as proven in a court of competent jurisdiction in a final and non-appealable decision. An Indemnified Party will notify the Company promptly of any claim for which it may seek indemnity. Failure by an Indemnified Party to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the subject Indemnified Party will cooperate in the defense. An Indemnified Party may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld and neither the Company nor any Guarantor may agree to any settlement without consent of the Indemnified Parties, which consent will not be unreasonably withheld.
(h)    The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture and the termination of the Note Documents or earlier resignation or removal of the Trustee.
(i)    To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, each Indemnified Party will have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as trustee, or the Collateral Agent, in its capacity as collateral agent, except, in the case of the Trustee, that held in trust to pay principal of, premium on, if any, or interest on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture or earlier resignation or removal of the Trustee.
(j)    When an Indemnified Party incurs expenses or renders services after an Event of Default specified in clause (vii) or (viii) of Section 6.01 hereof 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 Law.
(k)    The Trustee will comply with the provisions of TIA §313(b)(2) to the extent applicable. 
Section 7.08    Replacement of Trustee.
(c)    A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.
(d)    The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by providing 30 days’ notice to the Trustee and the Company in writing. The Company may remove the Trustee if:
(viii)    the Trustee fails to comply with Section 7.10 hereof;
(ix)    the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;
(x)    a custodian or public officer takes charge of the Trustee or its property; or
(xi)    the Trustee becomes incapable of acting.
(e)    If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.
(f)    If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.
(g)    If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.
(h)    A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will 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 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.
Section 7.09    Successor Trustee by Merger, etc.
If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.
Section 7.10    Eligibility; Disqualification.
There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition.
This Indenture will always have a Trustee who satisfies the requirements of TIA §310(a)(1), (2) and (5). The Trustee is subject to TIA §310(b).
Section 7.11    Preferential Collection of Claims Against Company.
The Trustee is subject to TIA §311(a), excluding any creditor relationship listed in TIA §311(b). A Trustee who has resigned or been removed shall be subject to TIA §311(a) to the extent indicated therein.
Section 7.12    Collateral Agent.
References to the Trustee in Sections 7.01(b) through (f) (“Duties of Trustee”), 7.02 (“Rights of Trustee”), 7.03 (“Individual Rights of Trustee”), 7.04 (“Trustee’s Disclaimer”), 7.07 (“Compensation and Indemnity”), 7.08 (“Replacement of Trustee”) and 7.09 (“Successor Trustee by Merger, etc.”) shall be read to apply to the Collateral Agent and the Security Documents, mutatis mutandis, in addition to this Indenture; provided that the Collateral Agent’s standard of care of gross negligence or willful misconduct shall not be affected or changed after the occurrence and during the continuation of an Event of Default. The privileges, rights, indemnities, immunities and exculpatory provisions contained in this Indenture, including the right to be indemnified, shall apply to the Collateral Agent, whether it is acting under this Indenture or the Security Documents, and shall be enforceable by the Collateral Agent.  Each Holder of Notes, by its acceptance of the Notes (a) consents to the terms of the Note Documents, (b) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Note Documents and (c) authorizes and instructs the Collateral Agent, on behalf of each Holder of Notes to enter into the Note Documents.
Section 7.13    Separate Trustees and Co-Trustees
(a)    Notwithstanding any other provisions hereof, at any time, for the purpose of meeting legal requirements applicable to it in the performance of its duties hereunder, the Trustee shall have the power to, and shall execute and deliver all instruments to, appoint one or more Persons to act as separate trustees or co-trustees hereunder, jointly with the Trustee, of any portion of the Collateral subject to this Indenture, and any such Persons shall be such separate trustee or co-trustee, with such powers and duties consistent with this Indenture as shall be specified in the instrument appointing such Person but without thereby releasing the Trustee from any of its duties hereunder.  If the Trustee shall request the Company to do so, the Company shall join with the Trustee in the execution of such instrument, but the Trustee shall have the power to make such appointment without making such request.  A separate trustee or co-trustee appointed pursuant to this Section 8.11 need not meet the eligibility requirements of Section 8.10.  No trustee hereunder shall be personally liable because of any act or omission of any other trustee hereunder and any appointed separate or co-trustee hereunder shall not be deemed an agent of the appointing trustee.
(b)    Every separate trustee and co-trustee shall, to the extent not prohibited by law, be subject to the following terms and conditions:
(iii)    the rights, powers, duties and obligations conferred or imposed upon such separate or co-trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate or co-trustee jointly, as shall be provided in the appointing instrument, except to the extent that under any law of any jurisdiction in which any particular act is to be performed any nonresident trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such separate trustee or co-trustee at the direction of the Trustee;
(iv)    all powers, duties, obligations and rights conferred upon the Trustee, in respect of the custody of all cash deposited hereunder shall be exercised solely by the Trustee; and
(v)    the Trustee may at any time by written instrument accept the resignation of or remove any such separate trustee or co-trustee, and, upon the request of the Trustee, the Company shall join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to make effective such resignation or removal, but the Trustee shall have the power to accept such resignation or to make such removal without making such request.  A successor to a separate trustee or co-trustee so resigning or removed may be appointed in the manner otherwise provided herein.
(c)    Such separate trustee or co-trustee, upon acceptance of such trust, shall be vested with the estates or property specified in such instruments, jointly with the Trustee, and the Trustee shall take such action as may be necessary to provide for (i) the appropriate interest in the Collateral to be vested in such separate trustee or co-trustee and (ii) the execution and delivery of any transfer documentation or bond powers that may be necessary to give effect to the transfer of the Lien hereof to the co-trustee. Any separate trustee or co-trustee may, at any time, by written instrument constitute the Trustee, its agent or attorney-in-fact with full power and authority, to the extent permitted by law, do all acts and things and exercise all discretion authorized or permitted by it, for and on behalf of it and in its name.  The Trustee shall not be responsible for any action or inaction of any separate trustee or co-trustee.  If any separate trustee or co-trustee shall be dissolved, become incapable of acting, resign, be removed or die, all the estates, property, rights, powers, trusts, duties and obligations of said separate trustee or co-trustee, so far as permitted by law, shall vest in and be exercised by the Trustee, without the appointment of a successor to said separate trustee or co-trustee, until the appointment of a successor to said separate trustee or co-trustee is necessary as provided in this Indenture.
(d)    Any notice, request or other writing, by or on behalf of any Holder, delivered to the Trustee shall be deemed to have been delivered to all separate trustees and co-trustees.
(e)    Although co-trustees may be jointly liable, no co-trustee or separate trustee shall be severally liable by reason of any act or omission of the Trustee or any other such trustee hereunder.
(f)    No appointment of a separate trustee or co-trustee pursuant to this Section 7.13 shall relieve the Trustee of any of its obligations, duties or responsibilities hereunder in any way or to any degree.
ARTICLE 8     
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
Section 8.01    Option to Effect Legal Defeasance or Covenant Defeasance.
The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.
Section 8.02    Legal Defeasance and Discharge.
Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, at the written request and sole expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:
(iv)    the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium on, if any, or interest on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;
(v)    the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;
(vi)    the rights, powers, trusts, duties, indemnities and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and
(vii)    this Article 8.
Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.
Section 8.03    Covenant Defeasance.
Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 hereof and clause (iv) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(iii), (iv), (v), (vi), (vii) and (x) hereof will not constitute Events of Default.
Section 8.04    Conditions to Legal or Covenant Defeasance.
In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:
(xlvi)    the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, premium on, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;
(xlvii)    in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee and the Collateral Agent an Opinion of Counsel confirming that:
(A)    the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or
(B)    since the date of this Indenture, there has been a change in the applicable 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;
(xlviii)    in the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel 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 amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;
(xlix)    no Default or Event of Default shall have occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);
(l)    such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound;
(li)    the Company must deliver to the Trustee an Officers’ Certificate stating that the 
 
deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and
(lii)    the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.
The Collateral will be released from the Lien securing the Notes and the other Note Documents, as provided in Section 10.04 hereof, upon a Legal Defeasance or Covenant Defeasance in accordance with the provisions described above.
Section 8.05    Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.
Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will 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 Company acting as Paying Agent), to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.
The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof 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.
Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof 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(i) hereof), 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 Company.
Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium on, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.
Section 8.07    Reinstatement.
If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, 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 Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium on, if any, or interest on, any Note following the reinstatement of its obligations, the Company will 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.
ARTICLE 9     
AMENDMENT, SUPPLEMENT AND WAIVER
Section 9.01    Without Consent of Holders of Notes.
Notwithstanding Section 9.02 of this Indenture, without the consent of any Holder of Notes, the Company, the Guarantors, the Trustee and the Collateral Agent, if applicable, may amend or supplement this Indenture, the Notes, the Note Guarantees or any other Note Documents:
(viii)    to cure any ambiguity, defect or inconsistency;
(ix)    to provide for uncertificated Notes in addition to or in place of certificated Notes;
(x)    to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of the Notes and Note Guarantees by a successor to the Company or such Guarantor pursuant to Article 5 or Article 10 hereof;
(xi)    to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder;
(xii)    to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;
(xiii)    to conform the text of this Indenture, the Notes, the Note Guarantees or the Security Documents to any provision of the “Description of The New Notes” section of the Offer to Exchange, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Notes, the Note Guarantees or the Security Documents, which intent shall be evidenced by an Officers’ Certificate to that effect;
(xiv)    to enter into additional or supplemental Security Documents;
(xv)    to make, complete or confirm any grant of Collateral permitted or required by this Indenture or any of the Security Documents or any release of Collateral that becomes effective as set forth in this Indenture or any of the Security Documents;
(xvi)    to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the date of this Indenture;
(xvii)    to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes; or
(xviii)    with respect to the Security Documents to amend this Indenture or any of the Security Documents, as provided in the Intercreditor Agreement.
Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amendment or supplemental indenture, and upon receipt by the Trustee and the Collateral Agent of the documents described in Section 9.06 hereof, the Trustee and the Collateral Agent will join with the Company and the Guarantors in the execution of any amendment or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but neither the Trustee nor the Collateral Agent will be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under the Note Documents or otherwise.
Section 9.02    With Consent of Holders of Notes.
Except as provided below in this Section 9.02, the Company, the Trustee and the Collateral Agent, if applicable, may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10, and 4.14 hereof), the Notes, the Note Guarantees or any other Note Documents with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.
Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amendment or supplemental indenture, and upon the filing with the Trustee and/or the Collateral Agent, as the case may be, of evidence satisfactory to the Trustee and/or the Collateral Agent, as the case may be, of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee and/or the Collateral Agent, as the case may be, of the documents described in Section 9.06 hereof, the Trustee and/or the Collateral Agent, as the case may be, will join with the Company and the Guarantors in the execution of such amendment or supplemental indenture unless such amendment or supplemental indenture directly affects the Trustee’s and/or the Collateral Agent, as the case may be, own rights, duties or immunities under this Indenture, the other Note Documents or otherwise, in which case the Trustee and/or the Collateral Agent, as the case may be, may in its discretion, but will not be obligated to, enter into such amendment or supplemental Indenture.
It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.
After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):
(xxviii)    reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;
(xxix)    reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption or repurchase of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.14 hereof);
(xxx)    reduce the rate of or change the time for payment of interest, including default interest, on any Note;
(xxxi)    waive a Default or Event of Default in the payment of principal of, premium on, if any, or interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);
(xxxii)    make any Note payable in money other than that stated in the Notes;
(xxxiii)    make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, if any, on, interest on the Notes (other than as permitted by clause (vii) below);
(xxxiv)    waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.14 hereof);
(xxxv)    release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or
(xxxvi)    make any change in the preceding amendment and waiver provisions.
In addition, any amendment to, or waiver of, the provisions of this Indenture or any security document that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 662/3% in aggregate principal amount of the Notes then outstanding.
Section 9.03    Trust Indenture Act.
Every amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the TIA as then in effect. 
Section 9.04    Revocation and Effect of Consents.
Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.
Section 9.05    Notation on or Exchange of Notes.
The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.
Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.
Section 9.06    Trustee to Sign Amendments, etc.
The Trustee will sign any amendment or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors of the Company approves it. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment 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 Company and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions.
ARTICLE 10

(viii)    stating that, in the opinion of such counsel, no such action is necessary to maintain such Lien and assignment.
(e)    The Company will comply with the provisions of TIA § 314.
Section 10.03    Release of Liens on Collateral.
The Collateral Agent’s Second Liens upon the Collateral will be released in any one or more of the circumstances set forth in the Intercreditor Agreement, and in any such event, each of the Trustee and Collateral Agent shall release the Collateral upon request from Priority Lien Collateral Agent or the Priority Lien Representative, and neither the Trustee nor Collateral Agent shall be liable for verifying whether such release is authorized or permitted pursuant to the Indenture and  each of the Trustee and the Collateral Agent may conclusively rely on such request, and incur no liability for any releases effected pursuant to such request.
Section 10.04    Release of Liens in Respect of Notes.
(l)    The Collateral Agent’s Second Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other Obligations under this Indenture, and the right of the Holders of the Notes and such Obligations to the benefits and proceeds of the Collateral Agent’s Second Liens on the Collateral shall terminate and be discharged:

(ii)    upon a Legal Defeasance or Covenant Defeasance of the Notes as set forth in Article 8 hereof;
(iii)    upon payment in full and discharge of all Notes outstanding under this Indenture and all Obligations that are outstanding, due and payable under this Indenture at the time the Notes are paid in full and discharged;

The Company will furnish to the Trustee and the Collateral Agent, prior to each proposed release of Collateral pursuant to the Security Documents:
(i)    all documents required by TIA §314(d);

The Trustee and the Collateral Agent may, to the extent permitted by Sections 7.01 and 7.02 hereof, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained in such documents and such Opinion of Counsel. Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in good faith in reliance upon any such Officers’ Certificate or Opinion of Counsel, and notwithstanding any term hereof or in any Note Document to the contrary, the Trustee and Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and until it receives such Officers’ Certificate and Opinion of Counsel.
Section 10.06    Certificates of the Trustee.
Neither the Trustee nor the Collateral Agent shall have any duty to confirm the legality, sufficiency, genuineness, accuracy, contents or validity of any documents (or any signature appearing therein). Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in good faith in reliance upon any documents delivered to them pursuant to Section 10.05 hereof, and notwithstanding any term hereof or in any Note Document to the contrary, neither the Trustee nor the Collateral Agent shall be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and until it receives such documents.
Section 10.07    Authorization of Actions to Be Taken Under the Security Documents.
Subject to the provisions of Section 7.01 and 7.02 hereof and to the terms of the Intercreditor Agreement, the Trustee and the Collateral Agent may, on behalf of the Holders of Notes,  take all actions to:
(iii)    enforce any of the terms of the Security Documents; and
(iv)    collect and receive any and all amounts payable in respect of the Obligations of the Company hereunder and under the Security Documents.
The Collateral Agent will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and proceedings to preserve or protect its interests and the interests of the Holders of Notes in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes, of the Collateral Agent or of the Trustee). Nothing in this Section 10.07 shall be considered to impose any such duty or obligation to act on the part of the Trustee or the Collateral Agent.
Notwithstanding the foregoing, the Collateral Agent or the Trustee may, at the expense of the Company, request the direction of the Holders of Notes with respect to any such actions and upon receipt of the written consent of Holders of at least a majority in aggregate principal amount of the then outstanding Notes, shall take such actions; provided that all actions so taken shall, at all times, be in conformity with the requirements of the Intercreditor Agreement.
Section 10.08    Authorization of Receipt of Funds by the Trustee Under the Security Documents.
Subject to the terms of the Intercreditor Agreement, proceeds in respect of the Collateral received by the Collateral Agent shall be passed on to the Trustee. The Trustee is authorized to receive any funds for the benefit of the Holders of Notes distributed under the Security Documents, and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.
Section 10.09    Collateral Agent.
(g)    Wilmington Savings Fund Society, FSB, is hereby appointed as Collateral Agent and shall be authorized to appoint co-Collateral Agents as necessary in its sole discretion. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions of this Indenture and the Security Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Security Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, the Company or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.
(h)    The Collateral Agent makes no representations as to, and shall not be responsible for the existence, genuineness, value, sufficiency or condition of any of the Collateral or as to the security afforded or intended to be afforded thereby, hereby or by any Security Document, or for the validity, perfection, priority or enforceability of the Liens or security interests in any of the Collateral created or intended to be created by any of the Security Documents, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder,  for the validity or sufficiency of the Collateral, any Security Documents or any agreement or assignment thereof contained in any provision thereof, for the validity of the title of the Company or any Guarantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral, all such responsibilities and obligations being responsibilities and obligations of the Company and the Guarantors. The Collateral Agent shall not have any responsibility for recording, registering, filing, re-recording, re-registering or refiling any supplemental indenture, financing statement, continuation statement, document, instrument or other notice in any public office at any time or times or to otherwise take any action to perfect or maintain the perfection of any security interest granted to it under the Security Documents or otherwise (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder or under any Security Document) and such responsibility shall be solely that of the Company.
(i)    The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication, document or conversation (including those by telephone or e-mail) believed by it to be genuine and correct and to have been signed, sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the Company or any Guarantor), independent accountants and other experts and advisors selected by the Collateral Agent. The Collateral Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper or document. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture or the Security Documents in accordance with a request, direction, instruction or consent of the Company, the Trustee or the Holders of a majority in aggregate principal amount of the then outstanding Notes.
This Article 10 and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof.  Each Holder of Notes, by its acceptance of the Notes (a) consents to the terms provided for in the Intercreditor Agreement, (b) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes and instructs the Trustee and the Collateral Agent, in each case, on behalf of each Holder of Notes to enter into the Intercreditor Agreement as Second Lien Representative and as Second Lien Collateral Agent (as such terms are defined in the Intercreditor Agreement), in each case, on behalf of such Holders of Notes.  In addition, each Holder of Notes authorizes and instructs the Trustee and the Collateral Agent to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder, to add additional Indebtedness as Second Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Second Lien Debt then outstanding.  The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company and certain of its Subsidiaries, and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.
ARTICLE 11     
NOTE GUARANTEES
Section 11.01    Guarantee.
(f)    Subject to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes, the Security Documents or the obligations of the Company hereunder or thereunder, that:
(v)    the principal of, premium, if any, on, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest on, the Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee and the Collateral Agent hereunder or thereunder or under any Security Document will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and
(vi)    in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will 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 will 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.
(g)    The Guarantors hereby agree that their obligations hereunder are 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 Company, 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 Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.
(h)    If any Holder, the Collateral Agent or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee, the Collateral Agent or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.
(i)    Each Guarantor agrees that it will 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, the Collateral Agent and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof 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 (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will 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 Guarantee.
Section 11.02    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 Bankruptcy Law, 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 such Guarantor will be limited to the maximum amount that 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 11, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.
Section 11.03    Execution and Delivery of Note Guarantee.
To evidence its Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.
Each Guarantor hereby agrees that its Note Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.
If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.
The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.
In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Domestic Subsidiary after the date of this Indenture, if required by Section 4.15 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 11, to the extent applicable.
Section 11.04    Guarantors May Consolidate, etc., on Certain Terms.
Except as otherwise provided in Section 11.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:
(iv)    immediately after giving effect to such transaction, no Default or Event of Default exists; and
(v)    either:
(A)    subject to Section 11.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under its Note Guarantee, this Indenture and the Security Documents on the terms set forth herein or therein, pursuant to a supplemental indenture and appropriate security documents in form and substance reasonably satisfactory to the Trustee; or
(B)    the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation, Section 4.10 hereof.
In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.
Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (ii)(A) and (B) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.
Section 11.05    Releases.
(a)    The Note Guarantee of a Guarantor will automatically be released:
(xxxvii)    In connection with any sale or other disposition of all or substantially all of the assets of that Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate the provisions described in Section 4.10 hereof;
(xxxviii)    in connection with any sale or other disposition of Capital Stock of that Guarantor by way of merger, consolidation or otherwise to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate the provisions described in Section 4.10 hereof and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;
(xxxix)    if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;
(xl)    upon legal defeasance, covenant defeasance or satisfaction and discharge of this Indenture as provided in Articles 8 and 12 hereof;
(xli)    upon the liquidation or dissolution of such Guarantor provided no Default or Event of Default has occurred or is continuing; or
(b)    if consent to such release has been given by an Act of Supermajority Debtholders.
(c)    Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 11.05 will remain liable for the full amount of principal of, premium on, if any, and interest on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.
ARTICLE 12     
SATISFACTION AND DISCHARGE
Section 12.01    Satisfaction and Discharge.
This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration, of transfer or exchange of the Notes and as otherwise provided in this Indenture), when:
(xlii)    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 been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or
(B)    all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, 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, if any, and interest to the date of maturity or redemption;
(xliii)    in respect of subclause (B) of clause (i) of this Section 12.01, no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);
(xliv)    the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and
(xlv)    the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be.
In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.
The Collateral will be released from the Lien securing the Notes and the other Note Documents, as provided in Section 10.04 hereof, upon a satisfaction and discharge in accordance with the provisions described above.
Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (B) of clause (i) of this Section 12.01, the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.
Section 12.02    Application of Trust Money.
Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof 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 Company acting as its own Paying Agent), to the Persons entitled thereto, of the principal, premium, 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 12.01 hereof 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 Company’s 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 12.01 hereof; provided that if the Company has made any payment of principal of, premium on, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.
(i)INTEREST.  ION Geophysical Corporation, a Delaware corporation (the “Company”), promises to pay or cause to be paid interest on the principal amount of this Note at 9.125% per annum from April 28, 2016 until maturity.  The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year, except that the interest payment otherwise payable on June 15, 2021 will be payable on December 15, 2021, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”).  Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that, if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be June 15, 2016. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1% higher than the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.
(ii)    METHOD OF PAYMENT.  The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the June 1 and December 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest.  The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Paying Agent and Registrar within the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium on, if any, and interest on all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent.  Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.
(iii)    PAYING AGENT AND REGISTRAR.  Initially, Wilmington Savings Fund Society, FSB, the Trustee under the Indenture, will act as Paying Agent and Registrar.  The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Notes.  The Company or any of its Subsidiaries may act as Paying Agent or Registrar.
(iv)    INDENTURE AND SECURITY DOCUMENTS.  The Company has issued the Notes under an Indenture dated as of April 28, 2016 (the “Indenture”) among the Company, the Guarantors and the Trustee and the Collateral Agent.  The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA.  The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms.  To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.  The Notes are secured obligations of the Company.  The Notes are secured by a  second priority Lien in and on all the Collateral pursuant to the Security Documents referred to in the Indenture.
