 ARTICLE 7 
 COVENANTS 
 The Parties covenant
and agree as follows: 
  

	7.1	License Agreement 

 (a) Unless otherwise
agreed to in writing by the Parties, during the Term, Assignor shall not, with respect to the Acquired Royalty Payments (i) forgive, release, or compromise any amount owed or to become owing with respect to the Acquired Royalty Payments on or
after the Effective Date, (ii) modify, waive, cancel or otherwise relinquish any of the Acquired Royalty Payments under the License Agreement, or (iii) amend, restate or novate either the License Agreement or the Quencher Agreement in a
manner that could adversely affect, or diminish the value of, the Acquired Royalty Payments. 
 (b) During the Term, upon becoming aware of
any breach of the License Agreement arising with respect to the Acquired Royalty Payments, Assignor shall promptly notify Assignee in writing of such breach. 
 (c) During the Term and while any obligations remain outstanding under this Agreement, Assignor will not terminate, modify, or subcontract or otherwise delegate its obligations under the License Agreement without the
prior written consent of Assignee and will fulfill all of its supply obligations under the License Agreement. 
  

 - 13 - 

 (d) Assignor will promptly provide to the Assignee copies of all Reports delivered under the License
Agreement during the Term or after the Term to the extent the Reports relate to the Acquired Royalty Payments. 
 (e) Any royalty under any
of the Patents payable to Assignor arising from the sale of any Product which is a licensed product covered by both the License Agreement and the Quencher Agreement shall be a Royalty subject to, and shall be paid to Assignee under, the terms of
this Agreement. 
 (f) From time to time after the Effective Date, Assignee may change its nominee for purposes of the Authorization, and
upon request of Assignee, Assignor shall promptly execute and deliver to Assignee a new Authorization in respect of Assignee’s nominee as duly authorized agent. 
 (g) Epoch will not exercise its rights to inspect Licensee’s records relating to the Acquired Royalty Payments pursuant to the audit rights under Section 5.10 of the License Agreement without the prior
written consent of Assignee, which consent may be withheld in Assignee’s sole discretion. 
 (h) Assignee acknowledges that the License
Agreement may be terminated by the Licensee (other than by reason of an act or omission of Epoch which caused such termination) in accordance with Section 9.02(c) of the License Agreement, and that a termination of the License Agreement by
Licensee in accordance with such section would not in and of itself constitute a breach of this Section 8.1 or any other provision of this Agreement. Assignor covenants that in the event that the License Agreement is terminated by Licensee,
Assignor will use its commercially reasonable efforts to enter into a license agreement for the Products within the Field of Use for the Patents specified in the Licence Agreement or into a transaction to effect the exploitation for gain of those
rights (in either case a “Replacement Agreement”), and to effect an assignment to Assignee of the royalties or proceeds under that Replacement Agreement in order to achieve as closely as possible an economic result no worse to the
Assignee than if the License Agreement had not been terminated, and generally on terms and conditions that are acceptable to Assignee acting reasonably. Assignor shall consult with Assignee prior to entering into any Replacement Agreement and shall
keep Assignee informed as to the status of negotiations with respect to and completion of the Replacement Agreement. 
  

	7.2	Maintenance and Access to Records 

 Assignor
agrees that it will retain all books and records and any other documents, information and files relating to the Products generated by it or delivered to it by the Licensee during the Term and thereafter for such period as is required by Applicable
Law. So long as such books and records and such other documents, information and files are retained by Assignor, Assignee or its authorized representatives shall have reasonable access thereto during the Term and for a period of six months after the
end of the Term (the “Clean-Up Period”), provided that if at the end of the Clean-Up Period there is a bona fide dispute between the Parties with respect to any aspect of this Agreement, including as to whether or not
the Term or the Clean-Up Period has expired, then notwithstanding the expiry of the Clean-Up Period, this right shall continue. 
  

 - 14 - 

	7.3	Conduct of the Business 

 During the Term,
Assignor shall cause its business and other activities with respect to the Acquired Royalty Payments, the License Agreement, the Patents, the Products and the Know-How to be carried on in the ordinary course, consistent with past practice and shall
not take or permit to be taken any action that will have a material adverse effect on the Products. 
  

	7.4	True Sale 

 (a) Assignor and Assignee intend
and agree that the sale, assignment and transfer of the Acquired Royalty Payments under Section 2.1 (the “Assignment”) shall be, and is, a true sale by Assignor to Assignee that is absolute and irrevocable and that provides
Assignee with the full benefits of ownership of the Acquired Royalty Payments, and neither Assignor nor Assignee intends the transactions contemplated hereunder to be, or for any purpose to be characterized as, a loan from Assignee to Assignor.
Assignor waives any right to contest or otherwise assert that this Agreement is other than a true sale by Assignor to Assignee under Applicable Law, which waiver shall be enforceable against Assignor in any bankruptcy or insolvency proceeding
relating to Assignor. 
 (b) Assignor hereby consents to Assignee recording and filing, at any time during the Term, at Assignee’s sole
cost and expense, financing statements (and continuation statements with respect to such financing statements when applicable) meeting the requirements of Applicable Law in such manner and in such jurisdictions as are necessary or appropriate to
perfect the Assignment intended to be effected by this Agreement, including precautionary filings customary in true sale transactions. 
  

	7.5	Patent Obligations 

 (a) During the Term,
Assignor shall, at is own cost, in accordance with its standard procedures and with good practice, and subject to the rights of Licensee under the License Agreement, use its commercially reasonable efforts (including making payment of appropriate
fees to the USPTO) to, (i) prosecute and maintain in full force and effect each pending patent application worldwide included in the Patents, in particular, validate EP 0 819 133 in at least Great Britain, Germany, France, Spain and Italy by
April 2, 2008; (ii) maintain and keep in full force and effect any issued Patents in each of the countries worldwide in which Assignor has an issued patent, and (iii) maintain all Know-How relating to the Products in strict confidence
other than disclosure to Licensee in accordance with the License Agreement. Assignor shall provide notice to Assignee of all information relating to the prosecution and/or validity or enforceability of any patent or application in the Patents,
including all correspondence to and from the USPTO or any other patent office in which any patent application is pending or from which any patent has issued. If practicable, such notice to Assignee shall be in sufficient time to allow Assignee to
comment, or act pursuant to section (b) below, on matters which may have a material effect on the scope, validity, or enforceability of any of the Patents. 
  

 - 15 - 

 (b) Assignor shall not during the Term without the prior written consent of Assignee abandon any of the
Patents or Know-How, or sell, transfer, assign or otherwise dispose of the Patents or Know-How to any Person and shall not grant any licenses thereunder other than (i) the license in the License Agreement, (ii) the license in the Quencher
Agreement, and (iii) any license for use outside the Field of Use as defined in the License Agreement or the Quencher Agreement that does not and would not materially interfere with or impair the value of the Acquired Royalty Payments. Assignee
shall have, at its option, the right to have Assignor assign to Assignee all right, title and interest in any Patent that Assignor decides to abandon. 
 (c) Assignor hereby grants to Assignee an irrevocable power of attorney with power of substitution to act in the place and stead of Assignor in performing the actions specified in (a)(i) and (a)(ii) above. Such power
is acknowledged by Assignor to be coupled with an interest and shall be exercisable during the Term immediately upon Assignor’s breach of the covenant in (a)(i) or (a)(ii) above. Upon the expiry of the Clean-Up Period, this power shall
terminate, provided that if at the end of the Clean-Up Period there is a bona fide dispute between the Parties with respect to any aspect of this Agreement, including as to whether or not the Term or the Clean-Up Period has expired, then
notwithstanding the expiry of the Clean-Up Period, this right shall continue. 
  

	7.6	Certain Conduct 

 During the Term, without
the prior written consent of Assignee, which consent shall not be unreasonably withheld, Assignor shall not: (i) create or suffer to exist any Encumbrance other than the Security Interest on any of the Acquired Royalty Payments or the License
Agreement; (ii) amend or terminate the License Agreement or fail to perform and fulfill its obligations under the License Agreement in accordance with the terms thereof if such amendment, termination or failure to perform would have a material
adverse affect on any of the Acquired Royalty Payments; (iii) sell, transfer, assign or otherwise dispose of any interest in the Patents other than pursuant to a Permitted Encumbrance, or (iv) agree to do any of the foregoing. 

 

	7.7	Indemnities 

 (a) Assignor hereby indemnifies
and agrees to hold Assignee harmless from any damages suffered or incurred by Assignee from and after the Effective Date to the extent resulting from (i) any material breach of a representation or warranty of Assignor contained herein, or
(ii) the material breach by Assignor of any covenant contained in this Agreement or any of the Closing Documents, or (iii) any Encumbrance of any of the Acquired Royalty Payments or the License Agreement, other than any Encumbrance created
by Assignee or a Permitted Encumbrance. 
 (b) Assignor hereby indemnifies and agrees to hold Assignee harmless from any damages suffered or
incurred by Assignee from and after the Effective Date to the extent resulting from any breach of the License Agreement by a party thereto, other than (i) the failure of Licensee to pay the royalties owing thereunder where such failure to pay
is not related to, resulting from or in response to a breach of the License Agreement by Assignor or (ii) a breach of a covenant or representation by a party to the License Agreement related to or resulting from one or both of the
parties’ inability to market, commercialize or exploit the Patents. 
  

 - 16 - 

	7.8	Third Party Claims Procedure 

 The
indemnified party shall give notice (the “Indemnity Notice”) to the indemnifying party specifying the particulars of any Third Party claim within ten (10) days after it receives notification of the claim; provided, however,
that failure to give such notice within such time period shall not prejudice the rights of the indemnified party except to the extent that the failure to give such notice materially adversely affects the ability of the indemnifying party to
defend the claim or to cure the breach of the representation, warranty, covenant or obligation giving rise to the claim. Subject to the terms of this Section 7.8, the indemnifying party shall have sole control over the defense and settlement of
such claim. The indemnifying party may not settle or compromise the claim without the prior written consent of the indemnified party unless such settlement or compromise (i) involves no payment (whether by cash, securities or other instrument),
assignment, granting of a license or admission of fault or wrongdoing by the indemnified party and (ii) the indemnified party receives a comprehensive general release of all claims from the applicable third parties. The indemnified party shall
provide to the indemnifying party, in confidence, all files, books, records and other information in its possession or control which may be relevant to the defense of such claim. The indemnified party shall co-operate in all reasonable respects in
the defense of such claim but at the expense of the indemnifying party. If the indemnifying party fails to diligently defend such claim throughout the period that such claim exists, its right to defend the claim shall terminate and the indemnified
party may assume the defense of such claim at the sole expense of the indemnifying party. In such event, the indemnified party may compromise or settle such claim, without the consent of the indemnifying party. 
 ARTICLE 8 
 GENERAL 

  

	8.1	Confidentiality 

 During the Term and for
five years thereafter, each of the Parties and their respective Affiliates, shall not use, reveal or disclose to Third Parties (other than their respective financial institutions, counsel and advisors and then only on a confidential basis) any
information received from any other Party in connection with this Agreement (including any information or reports provided to Assignee or its Affiliates by Licensee, and including the terms of this Agreement), without first obtaining the written
consent of the disclosing or other Parties, except as may be otherwise provided herein. This confidentiality obligation shall not apply to information which (a) is or becomes a matter of public knowledge (other than as a result of a breach of
this Agreement), (b) is already in the possession of the receiving Party, (c) is disclosed to the receiving Party by a Third Party having the right to do so, or (d) is required by Applicable Law to be disclosed, including pursuant to
applicable securities laws provided that if Assignor is required to file this Agreement or any other Closing Document in any registry of repository accessible by the public, Assignor will use its commercially reasonable efforts to obtain
confidential treatment for commercially sensitive information from such documents and shall co-operate and consult with Assignee in that regard. The Parties shall take reasonable measures to assure that no unauthorized use or disclosure is made.

the exercise of any other right.

and any and all successors thereto, as trustee (in such capacity, the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”). 
 The Issuers, the Guarantors, the Trustee and the Collateral Agent agree as follows for the benefit of each other and for the equal and ratable benefit of
the Holders (as defined) of the Notes:

 “Acquired Debt” means,
with respect to any specified Person: 
 (1) Indebtedness of any other Person existing at the time such other Person is merged
with or into or became a Subsidiary of such specified Person (regardless of the form of the applicable transaction by which such Person became a Subsidiary) or expressly assumed in connection with the acquisition of assets from any such Person,
whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person or of such Indebtedness being incurred in connection with
the acquisition of assets; and 
 (2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person.

Registration Rights Agreement. 
 “Additional Notes” means Notes (other than the Initial Notes) issued after the Issue Date

case (i) any such expenditure made to restore, replace or rebuild property to the condition of such property immediately prior to any damage, loss, destruction or condemnation of such property, to the extent such expenditure is made with

 1 

 
expenditure constituting reinvestment of the Net Proceeds of any Asset Sale permitted by this Indenture and (iii) any Capital Expenditures made or
deemed to be made resulting from the acquisition of property or assets by any New Parent, the Company or any of their Restricted Subsidiaries the consideration for which acquisition was Equity Interests (other than Disqualified Stock) of any New
Parent, the Company or any of their Restricted Subsidiaries otherwise permitted by this Indenture.

specified Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any
Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise; provided that

 (b) the principal amount of the Note, if greater.

or other disposition of all or substantially all of the assets of either (a) any New Parent and its Restricted Subsidiaries taken as a whole or (b) the Company and its Restricted Subsidiaries taken as a whole will, in each case, be
governed by Section 4.10 hereof, and/or Section 5.01 hereof, and not by Section 4.11 hereof; and 
 (2) the
issuance or sale of Equity Interests in any of any New Parent’s or the Company’s Restricted Subsidiaries or the sale of Equity Interests in any of their Subsidiaries; provided that, for the avoidance of doubt, the sale of Equity
Interests of the Company (and any New Parent) will be governed by Section 4.10 and Article 5 of this Indenture and not by Section 4.11 of this Indenture.

equivalent to the Fair Market Value of the assets (together with any cash or Cash Equivalents) to be received by the Company or such Restricted Subsidiary. 
 “Attributable Debt” means, in respect of a sale and leaseback transaction, 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

after the passage of time. The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning.

right of participation with Capital Stock. 
 “Cash Equivalents” means: 
 (1) United States dollars;

$2.0 million in the aggregate at any one time; and 
 (7) money market funds at least 95% of the assets of which constitute
Cash Equivalents of the kinds set forth in clauses (1) through (7) of this definition.

Person other than a Permitted Holder becomes the Beneficial Owner, directly or indirectly, of more of the Voting Stock of any New Parent or the Company (measured by voting power rather than number of shares) than is at the time Beneficially Owned by
the Permitted Holders in the aggregate; or 
 (5) after an initial public offering of any New Parent or the Company, the first
day on which a majority of the members of the Board of Directors of such New Parent or the Company, as the case may be, are not Continuing Directors. 
 For the avoidance of doubt, a Change of Control will not be deemed to have occurred solely as a result of the formation of and the transfer of ownership of any Equity Interests of the Company or any New Parent to any
New Parent; provided that none of the events set forth in paragraphs (1) through (5) above has occurred. 
 “Clearstream” means Clearstream Banking, S.A.

thereafter means any such successor. 
 “Collateral Agreements” means, collectively, the Intercreditor Agreement, the

 “Consolidated Cash Flow” means, with respect to any specified Person for any period, the Consolidated Net Income of such Person for such
period plus, without duplication: 
 (1) an amount equal to any extraordinary loss plus any net loss realized by such
Person or any of its Restricted Subsidiaries in connection with an Asset Sale, to the extent such losses were deducted in computing such Consolidated Net Income; plus 
 (2) provision for taxes based on income or profits of such Person and its Restricted Subsidiaries for such period, to the extent that such
provision for taxes was deducted in computing such Consolidated Net Income; plus 
 (3) the Fixed Charges of such
Person and its Restricted Subsidiaries for such period, to the extent that such Fixed Charges were deducted in computing such Consolidated Net Income; plus 
 (4) depreciation, amortization (including amortization of intangibles but excluding amortization of prepaid cash expenses that were paid

period) of such Person and its Restricted Subsidiaries for such period to the extent that such depreciation, amortization and other non-cash expenses were deducted in computing such Consolidated Net Income; minus 
 (5) non-cash items increasing such Consolidated Net Income for such period, other than the accrual of revenue in the ordinary course of
business. 
 in each case, on a consolidated basis and determined in accordance with GAAP, it being understood that for any reference period that includes
time prior to the date of formation of the Company and the reorganization that results in the Guarantors on the Issue Date becoming Subsidiaries of the Company, such amounts shall be determined on a combined rather than a consolidated basis in
accordance with GAAP. 
  

 6 

 Notwithstanding the preceding, the provision for taxes based on the income or profits of, and the
depreciation, amortization and other non-cash expenses of, a Restricted Subsidiary of any New Parent or the Company will be added to Consolidated Net Income to compute Consolidated Cash Flow of such New Parent or the Company, as the case may be,

 ARTICLE 2 
 THE NOTES 
 Section 2.01 Form and Dating. 

 (a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto.
The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be issued in minimum denominations of $2,000 and integral multiples of
$1,000 in excess thereof. 
 The Issuers may issue Additional Notes from time to time after the Issue Date provided such issuance and
incurrence would then comply with Section 4.14. The Initial Notes and the Additional Notes shall be treated as a single class for all purposes under this Indenture, and unless the context otherwise requires, all references to the
“Notes” shall include the Initial Notes, any Additional Notes and any Exchange Notes. 
 The terms and provisions contained in the
Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.
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. 
 (b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and
the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule
of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding
Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a
Global Note to reflect the amount of any 

  

 26 

 
increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the
direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 (c)
Temporary Global Notes. Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby
with the Trustee, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Issuers and
authenticated by the Trustee as hereinafter provided. 
 Following the termination of the Restricted Period, beneficial interests in the
Regulation S Temporary Global Note will be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the Trustee’s authentication of the Regulation S Permanent Global
Note, the Trustee will cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided. 
 (d) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the
“General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global
Note that are held by Participants through Euroclear or Clearstream. 
 Section 2.02 Execution and Authentication. 
 At least one Officer of each Issuer must sign the Notes for the Issuers 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 Issuers signed by
an Officer of each Issuer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount
of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.  

The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

  

 27 

 Section 2.03 Registrar and Paying Agent. 
 The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and
an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more
additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The
Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Trustee will
initially act as Paying Agent and Registrar. The Issuers or any of their Subsidiaries may act as Paying Agent or Registrar, so long as no Event of Default is continuing. 
 The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. 
 The Issuers initially appoint the Trustee to act as Custodian with respect to the Global Notes. 
 Section 2.04 Paying Agent to Hold Money in Trust. 
 The Issuers 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, premium, if any, or interest on the Notes, and will notify the Trustee of
any default by the Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by
it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuers or a Subsidiary) will have no further liability for the money. If the Issuers 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. Upon any bankruptcy or reorganization proceedings relating to the Issuers, 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). If the Trustee is not the Registrar, the Issuers
will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and
addresses of the Holders of Notes and the Issuers shall otherwise comply with TIA § 312(a). 
 Section 2.06 Transfer and Exchange.

 (a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee
of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be
exchanged by the Company for Definitive Notes if: 
 (1) the Issuers deliver to the Trustee notice from the Depositary that it
is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within 90 days after the date of such
notice from the Depositary; 
  

 28 

 (2) the Issuers in their sole
discretion determine that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; provided that in no event shall the Regulation S Temporary Global Note
be exchanged by the Issuers for Definitive Notes prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or 
 (3) there has occurred and is

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

 35

or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such
transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.11 and 9.05 hereof). 
 (3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (4) 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 Issuers, 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. 
 (5) Neither the Registrar nor the Issuers will be required: 
 (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the
day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

 If any mutilated Note is surrendered to the Trustee or the Issuers and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers 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 Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of (i) the Trustee to protect the Trustee and (ii) the Issuers to protect the Issuers, the Trustee, any
Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those set forth 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 Issuers or an Affiliate of the Issuers holds the Note; however, Notes held by the Issuers or a Subsidiary of the Issuers shall not be deemed to be outstanding for purposes of Section 3.07(c)
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 Issuers, 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 Issuers or any Guarantor, or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Issuers 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 the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes.

 Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an
Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes. Without unreasonable delay, the
Issuers will prepare and the Trustee will authenticate (upon receipt of an Authentication Order) 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 Issuers
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 (subject to the record retention requirement of the Exchange Act). Certification of the cancellation of all canceled Notes
will be delivered to the Issuers. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation. 
  

 37 

 Section 2.12 Defaulted Interest; Additional Interest. 
 The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any, and
interest (without regard to any applicable grace period) from time to time on demand at the rate equal to 2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided as set forth in the Notes and consistent with Section 4.01 hereof. The Issuers 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 Issuers 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 Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will mail or cause to be sent to Holders a notice that states
the special record date, the related payment date and the amount of such interest to be paid. 
 The Issuers will pay Additional Interest, if
any, to Holders of Notes pursuant to the Registration Rights Agreement. 
 All reference to “interest” in this Indenture and the
Notes mean the initial interest rate borne by the Notes and any increases in that rate due to defaulted interest or Additional Interest, unless this Indenture states otherwise.

 (A) any liabilities, as shown on such New Parent’s or the Company’s most recent combined or consolidated balance sheet, of such
New Parent, the Company or any of

their Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee)

 (B) any securities, notes or other obligations received by such New Parent, the Company or any of their Restricted Subsidiaries from such
transferee that are contemporaneously, subject to ordinary settlement periods, converted by such New Parent, the Company or such Restricted Subsidiary, as the case may be, into cash, to the extent of the cash received in that conversion; and

 (C) any stock or assets of the kind referred to in clauses (2) or (4) of Section 4.11(b) hereof.

Subsidiary, as the case may be, shall apply such Net Proceeds:

 Pending the final application of any Net Proceeds, such New Parent, the Issuers or the applicable Restricted Subsidiary, as the case may be, may temporarily reduce revolving credit borrowings or otherwise invest the
Net Proceeds in any manner that is not prohibited by this Indenture. 
 (c) Any Net Proceeds from Asset Sales that are not applied or
invested as provided Section 4.11(b) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $5.0 million, the Issuers will, within five days thereof, make an Offer to Purchase Notes
pursuant to this Section 4.10 and Section 3.09 (an “Asset Sale Offer”) to all Holders of Notes pursuant to Section 3.09 hereof and all holders of other Indebtedness that is pari passu with the Notes containing
provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be
purchased 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 and Additional Interest, if any, to the date of purchase, 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 pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and the Issuers or such other agent will select for such other pari passu Indebtedness to be purchased on a pro
rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
  

 48 

 (d) Any New Parent will not, the Issuers will not and none of them will permit their Restricted
Subsidiaries to, enter into or suffer to exist any agreement (other than any agreement governing Credit Facilities for Indebtedness permitted to be incurred pursuant to clause (1) of Section 4.14(b)) that would place any restriction of any
kind (other than pursuant to law or regulation) on the ability of the Issuers to make an Asset Sale Offer.

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.

this Section 4.11 by virtue of such compliance. 
 Section 4.12 Excess Cash Flow Offer. 
 (a) If any New Parent and its Restricted Subsidiaries or the Company and its Restricted Subsidiaries has Excess Cash Flow for any fiscal year commencing
with the fiscal year ending December 31, 2008, each Holder will have the right to require the Issuers to repurchase all or any part of that Holder’s Notes (in minimum amounts of $2,000 and integral multiples of $1,000) at a purchase price
in cash equal to 101% of the principal amount of the Notes repurchased, plus any accrued and unpaid interest and Additional Interest, if any, to the date of purchase (subject to the rights of Holders of Notes on the relevant Record Date to receive
interest due on the relevant Interest Payment Date that is on or prior to the date of repurchase), with 50% of Excess Cash Flow of such New Parent and its Restricted Subsidiaries or the Company and its Restricted Subsidiaries, in each case, on a
consolidated basis for such fiscal year (less the amount of any open market purchases and any redemptions of Notes pursuant to this Indenture made during such fiscal year). 
 (b) Within 90 days after the end of any fiscal year, commencing with the fiscal year ending December 31, 2008, the Issuers will send a notice to
each Holder and the Trustee describing the offer to repurchase Notes with Excess Cash Flow (the “Excess Cash Flow Offer”) and offering to purchase Notes on the date specified in the notice, which date will be no earlier than 30 days
and no later than 60 days from the date such notice is sent. The Issuers will be required to purchase Notes validly tendered in response to an Excess Cash Flow Offer in accordance with the procedures set forth in this Section 4.12 and
Section 3.09 and such notice. The Issuers will not be required to make an Excess Cash Flow Offer if the Excess Cash Flow for such relevant fiscal year is less than $5.0 million. With respect to each Excess Cash Flow Offer, the Issuers shall be
entitled to reduce the applicable amount of the Excess Cash Flow Offer (the “Excess Cash Flow Offer Amount”) with respect thereto by the aggregate repurchase price of any Notes theretofore repurchased by the Issuers in the open
market or redeemed by the Issuers pursuant to this Indenture (to the extent such amount has not previously reduced any Excess Cash Flow Offer Amount). If the aggregate principal amount of Notes tendered pursuant to an Excess Cash Flow Offer exceeds
the Excess Cash Flow Offer Amount, the Trustee will select the Notes to be accepted for purchase on a pro rata basis. If the aggregate repurchase price of Notes tendered pursuant to an Excess Cash Flow Offer is less than the applicable Excess Cash
Flow Offer Amount, the Issuers may, subject to the other provisions of this Indenture, use any such Excess Cash Flow for any purpose not otherwise prohibited by this Indenture.

except a payment of interest or principal at the Stated Maturity thereof; or 
 (4) make any Restricted Investment 

(all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted
Payments”), 
 unless, at the time of and after giving effect to such Restricted Payment: 
 (1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; 

(2) any such New Parent or the Company, as the case may be, would, at the time of such Restricted Payment and after giving pro forma
effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in
Section 4.14(a) hereof; and 
 (3) such Restricted Payment, together with the aggregate amount of all other Restricted
Payments made by such New Parent, the Company and their Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2) through (10) of paragraph (b) of this Section 4.13), is less than the
sum, without duplication, of: 
 (A) 50% of the Consolidated Net Income of such New Parent or the Company, as the case may be,
for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing after the Issue Date to the end of such New Parent’s or the Company’s, as the case may be, most recently ended fiscal quarter for
which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus 
  

 50 

 (B) subject to Section 4.14(b)(2), 100% of the aggregate net cash proceeds received
by such New Parent or the Company, as the case may be, since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of such New Parent or the Company (other than Disqualified Stock), as the case
may be, or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of such New Parent or the Company, as the case may be, that have been converted into or exchanged for such Equity

 (C) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for
cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment; plus 
 (D) to the extent that any Unrestricted Subsidiary of such New Parent or the Company designated as such after the Issue Date is
redesignated as a Restricted Subsidiary after the Issue Date, the lesser of (i) the Fair Market Value of such New Parent’s or the Company’s Investment in such Subsidiary, as the case may be, as of the date of such redesignation or
(ii) such Fair Market Value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary after the Issue Date; plus 
 (E) 50% of any dividends received by such New Parent, the Company or any of their Restricted Subsidiaries, as the case may be, after the
Issue Date from an Unrestricted Subsidiary of such New Parent or the Company, to the extent that such dividends were not otherwise included in the Consolidated Net Income of such New Parent or the Company, as the case may be, for such period.

 (b) So long as no Default has occurred and is continuing or would be caused thereby (provided that with respect to clause (9) below,
the no Default limitation is not required), the preceding provisions will not prohibit: 
 (1) the payment of any dividend or
distribution or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or distribution or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the
dividend, distribution or redemption payment would have complied with the provisions of this Indenture; 
 (2) the making of
any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of any such New Parent or the Company, as the case may be) of, Equity Interests of such New Parent or the
Company (other than Disqualified Stock), as the case may be, or from the substantially concurrent contribution of common equity capital to such New Parent or the Company, as the case may be; provided that the amount of any such net cash
proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(B) of paragraph (a) of this Section 4.13; 
 (3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of such New Parent, the Company or any Guarantor that is contractually subordinated to the Notes or to any Note
Guarantee with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness; 
  

 51 

 (4) the repurchase, redemption or other acquisition or retirement for value of any Equity
Interests of such New Parent, the Company or any of their Restricted Subsidiaries held by any current or former officer, director or employee of such New Parent, the Company or any of their Restricted Subsidiaries, as the case may be, pursuant to an
agreement approved by the Board of Directors of such New Parent or the Company, as the case may be; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $500,000 in any
twelve-month period; 
 (5) the repurchase of Equity Interests deemed to occur upon the exercise of stock options to the
extent such Equity Interests represent a portion of the exercise price of those stock options or the repurchase of stock appreciation rights by way of cashless exercise or in connection with the satisfaction of withholding tax obligations;

 (6) the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of
Disqualified Stock of such New Parent, the Company or any of their Restricted Subsidiaries issued after the Issue Date in accordance with the Fixed Charge Coverage Ratio test set forth in Section 4.14(a) hereof; 
 (7) in connection with an acquisition by such New Parent, the Company or any of their Restricted Subsidiaries, the return to such New
Parent, the Company or any of their Restricted Subsidiaries, as the case may be, of Equity Interests of such New Parent, the Company or such Restricted Subsidiary constituting a portion of the purchase price consideration in settlement of
indemnification claims;

securities proposed to be transferred or issued by such New Parent, the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued
by this covenant will be determined by the Board of Directors of such New Parent or the Company, whichever entity is then the ultimate parent company, whose resolution with respect thereto will be delivered to the Trustee. Such Board of
Directors’ determination must be based upon an opinion or appraisal issued by a reputable accounting, appraisal or investment banking firm if the Fair Market Value exceeds $5.0 million. 
 Section 4.14 Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) Any New Parent will not, the Company will not and neither of them will permit any of their 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 any such New Parent or the Company will not issue any Disqualified Stock and neither of them
will permit any of their Restricted Subsidiaries to issue any shares 

  

 52 

 
of preferred stock; provided, however, that such New Parent or the Company, whichever entity is then the ultimate parent 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 such New Parent’s or the Company’s, as the case may
be, 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 2.5 to 1 until December 31, 2009 and 3.0 to 1 thereafter, in each case, 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 4.14(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
 (1) the incurrence by such New Parent, the Company and any Guarantor of additional Indebtedness and letters of credit under any Credit
Facility (A) in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum stated amount thereof of the Company and its Restricted
Subsidiaries thereunder) not to exceed $20.0 million, less the aggregate amount of all Net Proceeds of Asset Sales applied by any such New Parent, the Company or any of their Restricted Subsidiaries since the Issue Date to repay any term
Indebtedness under a Credit Facility or to repay any revolving credit Indebtedness under a Credit Facility and in each case, effect a corresponding commitment reduction thereunder pursuant to Section 4.11 hereof; 
 (2) (A) the incurrence by any such New Parent, the Company and their Restricted Subsidiaries of Existing Indebtedness and
(B) encumbrances or restrictions existing under agreements existing on the Issue Date as in effect on that date; 
 (3)
the incurrence by any such New Parent, the Company and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees to be issued on the Issue Date and the Exchange Notes and the related Note Guarantees to be issued
pursuant to the Registration Rights Agreement; 
 (4) the incurrence by any such New Parent, the Company or any of their
Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, 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 any such New Parent, the Company or any of their Restricted Subsidiaries, as the case may be, 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 (4), not to exceed $10.0 million at any time outstanding; 
 (5) the incurrence by any such New Parent, the Company or any of their 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 4.14(a)
hereof or clauses (2), (3), (4), (5) or (12) of this Section 4.14(b); 
  

 53 

 (6) the incurrence by any such New Parent, the Company or any of their Restricted
Subsidiaries of intercompany Indebtedness between or among such New Parent, the Company and any of their Restricted Subsidiaries; provided, however, that: 
 (A) if such New Parent, the Company or any Guarantor is the obligor on such Indebtedness and the payee is not such New Parent, the Company
or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes and the Note Guarantees; and 
 (B) any (i) subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other
than such New Parent, the Company or any of their Restricted Subsidiaries, or (ii) sale or other transfer of any such Indebtedness to a Person that is not any of such New Parent, the Company or any of their Restricted Subsidiaries, will be
deemed, in each case, to constitute an incurrence of such Indebtedness by such New Parent, the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
 (7) the issuance by any such New Parent’s or the Company’s Restricted Subsidiaries to such New Parent, the Company or to any of
their Restricted Subsidiaries of shares of preferred stock; provided, however, that any (A) subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than such New Parent,
the Company or such Restricted Subsidiary, or (B) sale or other transfer of any such preferred stock to a Person that is not any of such New Parent, the Company or such Restricted Subsidiary, 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 (7); 
 (8) the
incurrence by any such New Parent, the Company or any of their Restricted Subsidiaries of Hedging Obligations in the ordinary course of business; 
 (9) the guarantee by any such New Parent, the Company or any of the Guarantors of Indebtedness of such New Parent, the Company or any of their Restricted Subsidiaries, as the case may be, that was permitted to be
incurred by another provision of this Section 4.14; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable,
to the same extent as the Indebtedness guaranteed; 
 (10) the incurrence by any such New Parent, the Company or any of their
Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, bids, performance and surety bonds in the ordinary course of business, including Note Guarantees or
obligations of such New Parent, the Company or such Restricted Subsidiary, as the case may be, with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for an obligation for money borrowed);

 (11) the incurrence by any such New Parent, the Company or any of their 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; and 
 (12) the incurrence by any such New Parent, the Company or any of the Guarantors of additional Indebtedness in an aggregate principal
amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, 

  

 54 

 
refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (12), not to exceed $5.0 million at any one time
outstanding after giving pro forma effect to such incurrence and the application of the proceeds therefrom. 
 Any New Parent and the Issuers
will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of such New Parent, the Issuers or such Guarantor unless such
Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in
right of payment to any other Indebtedness of the Issuers solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 
 For purposes of determining compliance with this Section 4.14, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt set forth in clauses
(1) through (12) of Section 4.14(b), or is entitled to be incurred pursuant to Section 4.14(a), any such New Parent or the Company, as the case may be, will be permitted to classify such item of Indebtedness on the date of its
incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.14, and such item of Indebtedness will be treated as having been incurred pursuant to such category. Indebtedness
under Credit Facilities outstanding on the Issue Date and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.
The accrual of interest, the accretion or amortization of original issue discount, if applicable, 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 Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance
of Disqualified Stock for purposes of this Section 4.14; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of such New Parent or the Company, as the case may be, as
accrued. Notwithstanding any other provision of this Section 4.14, the maximum amount of Indebtedness that any such New Parent, the Company or any Restricted Subsidiary may incur pursuant to this covenant 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 4.15 Limitation on Capital Expenditures. 
 Any New Parent will not, the Company will not and neither of
them will permit any of their Restricted Subsidiaries to make or commit to make any Capital Expenditure, except Adjusted Capital 

  

 55 

 
Expenditures not exceeding the amount set forth below for such period, provided that the amount of Adjusted Capital Expenditures permitted in any fiscal year
may increase beyond the amount set forth below by the sum of the amounts contained in the second clause (3) in Section 4.13(a) provided that any such increase in Adjusted Capital Expenditures made with such amount will be excluded from the
sum of the amounts in such clause (3) in Section 4.13(a)(3):

permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital Stock to any such New Parent, the Company or any of their Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or

will not apply to encumbrances or restrictions existing under or by reason of: 
 (1) agreements governing Existing
Indebtedness and any Credit Facilities as in effect on the Issue Date or permitted by Section 4.14(b)(1) and any amendments, restatements, modifications, renewals, supplements, extensions, refundings, replacements or refinancings of those
agreements; provided that the amendments, restatements, modifications, renewals, supplements, extensions, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other
payment restrictions than those contained in those agreements on the Issue Date; 
 (2) this Indenture, the Notes and the Note
Guarantees; 
 (3) applicable law, rule, regulation or order; 
 (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by any such New Parent, the Company or any of their
Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred or issued in connection with or in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this
Indenture to be incurred; 
 (5) customary non-assignment provisions in leases, contracts and licenses entered into in the
ordinary course of business, including by reason of customary provisions restricting the transfer of copyrighted or patented materials consistent with industry practice; 
 (6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose
restrictions on the property purchased or leased of the nature set forth in clause (3) of the preceding paragraph; 
 (7)
any agreement for the sale or other disposition of a Restricted Subsidiary or assets that restricts distributions by that Restricted Subsidiary pending the sale or other disposition; 
  

 57 

 (8) 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;

 (11)
restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business; and

 Section 4.18 Transactions with Affiliates. 
 (a) Any New Parent will not, the Company will not and neither of them will permit any of their 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 such New Parent or the Company, as the case may be (each, an
“Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to
such New Parent, the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by such New Parent, the Company or such Restricted Subsidiary, as the case may be, with an unrelated Person or,
if there is no such comparable transaction, on terms that are fair and reasonable to such New Parent, the Company or such Restricted Subsidiary and reflect an arms’-length negotiation as determined by the Independent Directors; 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $500,000, whether or not subject to the following clause (2)(B) of this
Section 4.18, a resolution of the Board of Directors of such New Parent or the Company, whichever is then the ultimate parent company, set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this
covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of such Board of Directors who are Independent Directors; and 
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$2.5 million, an opinion as to the fairness to such New Parent, the Company or such Restricted Subsidiary, as the case may be, of such Affiliate Transaction from a financial point of view issued by a reputable accounting, appraisal or investment
banking firm. 
  

 58 

 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be
subject to the provisions of Section 4.18(a): 
 (1) any employment agreement, employee benefit plan, officer or director
indemnification agreement or any similar arrangement entered into by any such New Parent, the Company or any of their Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto; 
 (2) transactions between or among any such New Parent, the Company and/or their Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of any such New Parent or the
Company solely because such New Parent or the Company, as the case may be, owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 
 (4) payment of reasonable directors’ fees to Persons who are not employees of any such New Parent or the Company, whichever entity is
then the ultimate parent company; 
 (5) any issuance of Equity Interests (other than Disqualified Stock) of any such New
Parent or the Company, whichever entity is then the ultimate parent company, to Affiliates of such New Parent or the Company; 
 (6) Restricted Payments that do not violate the provisions of Section 4.13 hereof;

interfere with or impede the rights granted to Holders under the Registration Rights Agreement; 
 (9) Permitted Tax
Distributions; 
 (10) Permitted Affiliate Leases; and 
 (11) Permitted Affiliate Store Transactions. 
 Section 4.19 Business Activities. 
 The Company will not, and will not permit any of its Restricted Subsidiaries

 59 

 Section 4.20 Additional Guarantees. 
 If any New Parent, the Company or any of their Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the Issue Date that is not
declared by the Board of Directors of such New Parent or the Company, whichever entity is then the ultimate parent company, to be an Unrestricted Subsidiary, then such New Parent or the Company, whichever entity is then the ultimate parent company,
will (1) cause that newly acquired or created Domestic Subsidiary to (a) execute a supplemental indenture pursuant to which it becomes a Guarantor and (b) execute an amendment to the Registration Rights Agreement pursuant to which it
becomes subject to the obligations of a Guarantor thereunder, and (2) deliver an Opinion of Counsel and Officers’ Certificate satisfactory to the trustee, in each case within 10 business days of the date on which such Domestic Subsidiary
was acquired or created; provided that any Domestic Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary. 
 Section 4.21 Designation of Restricted and Unrestricted Subsidiaries. 
 (a) The Board of Directors of any New Parent or the Company, whichever entity is then the ultimate parent 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 such New Parent, the Company and their Restricted Subsidiaries in the Subsidiary
designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.13(a) hereof or under one or more clauses of the definition of
“Permitted Investments,” as determined by such New Parent or the Company, as the case may be. 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.” As of the Issue Date, all Subsidiaries of the Company will be Restricted Subsidiaries. 
 (b) 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 and will be deemed as of the date of such failure to be
a Restricted Subsidiary for purposes of this Indenture. In that event, any Indebtedness of such Subsidiary will be deemed to be incurred by such Restricted Subsidiary of any such New Parent or the Company as of such date and, if such Indebtedness is
not permitted to be incurred as of such date under Section 4.14, such New Parent, the Company or both of them, as the case may be, will be in Default of such covenant. 
 (c) The Board of Directors of a New Parent or the Company, whichever entity is then the ultimate parent company, may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary of such New Parent or the Company, as the case may be; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of such New Parent or
the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.14 hereof, calculated on a pro forma basis as if such
designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation. 
 (d) Any change in the designation of a Subsidiary of a New Parent or the Company as an Unrestricted Subsidiary or as a Restricted Subsidiary, as the case
may be, will be evidenced by such New Parent or the Company, whichever entity is then the ultimate parent company, to the Trustee by filing with the Trustee a certified copy of a resolution of its Board of Directors giving effect to such designation
and an Officers’ Certificate certifying that such designation complied with and was permitted by this Section 4.21.

 Section 4.22 Payments for Consent. 
 No New Parent, the Company or any of their Restricted Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that
consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.23 Impairment of Security Interest. 
 Subject to any Intercreditor Agreement, no New Parent, Issuer or

required by the Collateral Agreements or this Indenture. No New Parent, Issuer or any of their Restricted Subsidiaries will enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem,
defease or otherwise acquire or retire any Indebtedness of any Person, other than as permitted by this Indenture and the Collateral Agreements (including any Intercreditor Agreement). Any New Parent and the Issuers shall and they shall cause each
Guarantor to, at their sole cost and expense, execute and deliver all such agreements and instruments and take all further action as the Collateral Agent or the Trustee shall reasonably request to more fully or accurately describe the property
intended to be Collateral or the obligations intended to be secured by the Collateral Agreements. Any New Parent and the Issuers shall, and they shall cause each Guarantor to, at their sole cost and expense, file any such notice filings or other
agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Collateral Agreements. 
 Section 4.24 Real Estate Mortgages and Filings.

such property to be acquired by any such New Parent, the Company or a Domestic Subsidiary after the Issue Date with a purchase price in excess of $500,000 (within 90 days of the acquisition thereof), such New Parent or the Company, whichever entity
is then the ultimate parent company, shall deliver to the Collateral Agent (subject to the terms of the Intercreditor Agreement): 
 (1) fully executed counterparts of Mortgages, duly executed by such New Parent, the Company or the applicable Domestic Subsidiary, together with evidence of the completion (or satisfactory arrangements for the completion), of all recordings
and filings of such Mortgage as may be necessary to create a valid, perfected Lien, (subject to no liens other than Permitted Liens) against the properties purported to be covered thereby; 
 (2) mortgagee’s title insurance policies in favor of the Collateral Agent, as mortgagee for the ratable benefit of the Collateral
Agent, the Trustee and the Holders in an amount equal to 100% of the Fair Market Value of the Premises purported to be covered by the related Mortgage, insuring that title to such property is indefeasible and that the interests created by the
Mortgage constitute valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens together with typical endorsements, coinsurance and reinsurance and shall be accompanied by evidence of the payment in full of
all premiums thereon; 
  

 61 

 (3) with respect to each of the covered Premises, the most recent survey of such
Premises, together with either (i) an updated survey certification in favor of the Trustee and the Collateral Agent from the applicable surveyor stating that, based on a visual inspection of the property and the knowledge of the surveyor, there
has been no change in the facts depicted in the survey or (ii) an affidavit from such New Parent, the Company and the Guarantors, as the case may be, stating that there has been no change sufficient for the title insurance company to remove all
standard survey exceptions and issue the endorsements; 
 (4) an opinion from local counsel and special regulatory counsel in
each state where a Premises is located in form and substance reasonably satisfactory to the Collateral Agent and covering typical collateral matters, including without limitation, the enforceability of the relevant Mortgages; and 
 (5) an Officers’ Certificate by such 90th day certifying that all items in this Section 4.24 have been delivered. 
 Section 4.25 Disposal Well Mortgages and Filings 
 (a) With respect to any Disposal Well Assets owned by the Company or a Domestic Subsidiary on the Issue Date, or acquired by any New Parent, the Company or a Domestic Subsidiary after the Issue Date, subject to the immediately succeeding
paragraph, excluding in all cases Excluded Collateral: 
 (1) such New Parent or the Company, whichever entity is then the
ultimate parent company, shall deliver to the Collateral Agent, as mortgagee, fully executed counterparts of Mortgages or amendments and supplements to prior Mortgages, duly executed by such New Parent or the Company or the applicable Domestic
Subsidiary, as the case may be (together with evidence of the completion-or satisfactory arrangements for the completion-of all recordings and filings of such instruments), as may be necessary to create a valid, perfected Lien (subject to no Liens
other than Permitted Liens) on such Disposal Well Assets; and 
 (2) such New Parent or the Company, whichever entity is then
the ultimate parent company, shall deliver to the Collateral Agent an opinion from local counsel in each state where such Disposal Well Assets are located, covering typical matters, including without limitation, the enforceability of the relevant
Mortgage, as it may be supplemented or amended. 
 (b) Each such Mortgage, amendment or supplement shall be delivered by the Company promptly
after such Mortgage, amendment or supplement is entered into by the parties thereto, but in no event later than (1) 45 days either (a) after the acquisition of such Disposal Well Assets by any such New Parent, the Company or a Domestic
Subsidiary or (b) if such Disposal Well Assets were previously Excluded Collateral but have ceased to be Excluded Collateral, after such cessation or (2) the first business day of each fiscal quarter after such acquisition or cessation;
provided that if, prior to such date, such New Parent, the Company or a Domestic Subsidiary grants a Lien on such Disposal Well Assets to secure any applicable Credit Facility or any other Indebtedness secured by a first priority security
interest in the Collateral, such Mortgage, amendment or supplement must be delivered to the Collateral Agent at the same time as such grant to secure the first priority Liens. 
 (c) With respect to any Disposal Well Assets owned by the Company or a Domestic Subsidiary on, or acquired after the Issue Date that are situated on real
property for which the Company or any Domestic Subsidiary has not entered into a written lease or does not otherwise have a written leasehold interest therein, the Company shall, and shall cause any applicable Domestic Subsidiary to, use its
reasonable best efforts to (1) enter into such leases on commercially reasonable terms to permit the Collateral Agent to take a perfected security interest in such Disposal Well Assets and/or such leasehold interest, as the case may be, and
(2) perform the covenant set forth in subsection (a) of this Section 4.25. 
  

 62 

 Section 4.26 Leasehold Mortgages and Filings; landlord Waivers. 
 (a) Any New Parent, the Company and each of their Domestic Subsidiaries shall execute and file Mortgages with respect to such New Parent’s, the
Company’s and such Domestic Subsidiaries’ leasehold interests in the premises (the “Leased Premises”) leased by such New Parent or the Company or such Domestic Subsidiary, as the case may be, pursuant to written leases
that may be mortgaged by their terms or the terms of the landlord consents (collectively, the “Leases” and, individually, a “Lease”). 
 (b) Prior to or on the Issue Date or, if later, the effective date of any Lease, such New Parent, the Company and each such Domestic Subsidiary, as the case may be, shall provide to the Collateral Agent all of the
items set forth in clauses (2), (3) and (4) of Section 4.24 and shall use their commercially reasonable efforts to obtain an agreement executed by the lessor under the Lease, whereby such lessor consents to the Mortgage and waives or
subordinates its landlord Lien (whether granted by the instrument creating the leasehold estate or by applicable law), if any, and which shall be entered into by the Collateral Agent. 
 (c) Each of any New Parent, the Company and any Domestic Subsidiary that is a lessee of, or becomes a lessee of, real property, is, and will be, required
to use commercially reasonable efforts to deliver to the Collateral Agent a landlord waiver executed by the lessor of such real property; provided that if such lease is in existence on the Issue Date, such New Parent, the Company or the
Domestic Subsidiary that is the lessee thereunder shall have 90 days from the Issue Date to satisfy such requirement. 
 Section 4.27 Other
Collateral. 
 With respect to any assets or property (herein called “Other Collateral”) that is not Excluded Collateral
or addressed in or subject to Sections 4.24, 4.25 and 4.26 hereof or subject to the Collateral Agreements and is owned by the Company or a Domestic Subsidiary on the Issue Date or acquired by any New Parent, the Company or a Domestic Subsidiary, as
the case may be, after the Issue Date, such New Parent, the Company or such Domestic Subsidiary, as the case may be, will promptly grant Liens covering such Other Collateral to the Collateral Agent pursuant to a document or instrument on
commercially reasonable terms that contains provisions similar to those of the Security Agreement, if such Other Collateral is personal property, or provisions similar to those of the Mortgages set forth in Section 4.24 if such Other Collateral
is real property. 
 Section 4.28 Reports. 
 (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, any New Parent or the Company will furnish to the Trustee and the Holders of Notes or request the Trustee to
furnish to the Holders of Notes at the expense of the Issuers, within the time periods specified in the SEC’s rules and regulations: 
 (1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports, including a “Management’s Discussion and
Analysis of Financial Condition and Results of Operations” that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries, as the case may be; and 
 (2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

  

 63 

 in each case, within the time periods specified in the SEC’s rules and regulations, provided, that
(1) it is understood that the Company will furnish to the Holders of Notes an Annual Report on Form 10-K for the year ended December 31, 2007 by April 15, 2008, but such annual report need only include the financial statements, Notes
related thereto and a “Management’s Discussion and Analysis of Financial Condition and Results of Operation” in accordance with the rules and regulations of the SEC applicable to such report, in all material respects; and (2) if
a New Parent is formed, such New Parent may become the reporting company contemplated hereby, provided that such election would comply with the applicable rules and regulations of the SEC. 
 (b) All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each
annual report on Form 10-K of such New Parent or the Company, as applicable, will include a report on such New Parent’s or the Company’s consolidated financial statements by such New Parent’s or the Company’s certified
independent accountants. In addition, any such New Parent or the Company, whichever entity is then the ultimate parent company, will post the reports on its website within the time periods specified in the rules and regulations applicable to such
reports and, following the consummation of the exchange offer contemplated by the Registration Rights Agreement, such New Parent or the Company, whichever entity is then the ultimate parent company, will file a copy of each of the reports referred
to in clauses (1) and (2) above with the SEC for public availability within those time periods (unless the SEC will not accept such a filing). 
 (c) If, at any time after consummation of the exchange offer contemplated by the Registration Rights Agreement, any such New Parent or the Company, as the case may be, is no longer subject to the periodic reporting
requirements of the Exchange Act for any reason, such company will nevertheless continue filing the reports specified in the preceding paragraphs of this covenant with the SEC within the time periods specified above unless the SEC will not accept
such a filing. Neither any such New Parent nor the Company will take any action for the purpose of causing the SEC not to accept any such filings. 
 (d) Any such New Parent or the Company, as the case may be, will hold a quarterly conference call for the Holders of the Notes and securities analysts to discuss such financial information no later than ten Business Days after distribution
of such financial information. 
 (e) If any such New Parent or the Company, as the case may be, has designated any of its Subsidiaries as
Unrestricted Subsidiaries, then the quarterly and annual financial information required by paragraph (a) of this Section 4.28 will include a reasonably detailed presentation, either on the face of the financial statements or in the
footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of such New Parent or the Company, as the case may be, and their Restricted
Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of such New Parent or the Company, as the case may be. 
 (f) In addition, the Issuers and the Guarantors agree that, for so long as any Notes remain outstanding, if at any time they are not required or permitted to file with the SEC the reports required by this
Section 4.28, they will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Restricted Subsidiaries is or are merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale,
assignment, transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company or the applicable Restricted Subsidiaries), and
may exercise every right and power of the Company or Restricted Subsidiaries under this Indenture with the same effect as if such successor Person had been named as the Company or Restricted Subsidiaries herein; provided, however, that the
predecessor Company or Restricted Subsidiaries shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Company’s or the applicable Restricted Subsidiaries’
assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

 66 

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

 (8) any Collateral Agreement at any time for any reason shall cease to be in full force and effect in all material respects, or ceases to
give the Collateral Agent the Liens, rights, powers and privileges purported to be created thereby, superior to and prior to the rights of all third Persons other than the holders of Permitted Liens and subject to no other Liens except as expressly

 Section 6.02 Acceleration. 
 In the case of an Event of Default specified in clause
(9) or (10) of Section 6.01 hereof, with respect to any New Parent, the Company, any Restricted Subsidiary of such New Parent or the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of such New Parent
or 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. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by 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 except a continuing Default or Event of Default in the payment of principal, interest, premium or Additional Interest, if any. 
 Section 6.03 Other Remedies. 
 If an Event
of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes 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. 
 Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the
principal of, premium, if any, or interest on, the Notes (including in connection with an 

  

 68 

 
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. 
 Subject to Section 7.01(e), Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power, including with respect to the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee. The Trustee may
withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest, premium or
Additional Interest, if any. 
 Section 6.06 Limitation on Suits. 
 Subject to Section 7.01, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights
or powers under this Indenture at the request or direction of any Holders of Notes unless such Holders have offered to the Trustee an indemnity or security satisfactory to the Trustee against any loss, liability or expense. Except to enforce the
right to receive payment of principal, interest, premium, or Additional Interest, if any, when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

 (3) such Holders have offered the Trustee security or indemnity reasonably satisfactory to it against any loss, liability
or expense; 
 (4) the Trustee has not complied with such request within 60 days after the receipt of the request and the
offer of security or indemnity; and 
 (5) Holders of a majority in aggregate principal amount of the then outstanding Notes
have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 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, premium, if any, and 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 

  

 69 

 
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 or Collateral Agent. 
 If an Event of Default specified in Sections 6.01(1) or (2) hereof occurs and is
continuing, the Trustee or the Collateral Agent may recover judgment (a) in its own name and (b)(1) in the case of the Trustee, as trustee of an express trust or (2) in the case of the Collateral Agent, as collateral agent on behalf
of the Holders, in each case against the Issuers for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as
shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel. 
 Section 6.09 Trustee May File Proofs of Claim. 
 The Trustee shall be 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, or 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 shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, or their respective agents and counsel, and any other amounts due the Trustee or the Collateral Agent under the Collateral Agreements and Section 7.07
hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 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 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, as the case may be, to vote in respect of the claim of any Holder in any such proceeding.

 Section 6.10 Priorities. 
 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: 
 First: to the Trustee, the Collateral Agent, the Paying Agent and the Registrar for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all
advances made, by the Trustee or the Collateral Agent, as the case may be, and the costs and expenses of collection;

 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal,
premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 
 Third: to the Company or to such party as a court of competent jurisdiction shall direct. 
 The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
 Section 6.11 Undertaking for Costs. 
 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. 
 Section 6.12 Willful Event of Default. 
 In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Issuers with the intention of avoiding payment of the premium that the Issuers would have had to pay if the Issuers then had elected to redeem the Notes pursuant Sections 3.09, 4.10 or
4.11 hereof, an equivalent premium will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If an Event of Default occurs by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Issuers with the intention of avoiding the prohibition on redemption of the Notes prior to that date, then an additional premium specified in this Indenture will also become and be immediately due and payable to the
extent permitted by law upon the acceleration of the Notes. 
 ARTICLE 7 
 TRUSTEE 
 Section 7.01 Duties of Trustee. 
 (a) If an Event of Default 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. 
 (b) Except during the continuance of an Event of Default: 
 (1) 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 
  

 71 

 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the
truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and
opinions to determine whether or not they conform to the requirements of this Indenture. 
 (c) The Trustee may not be relieved from
liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1)
this paragraph does not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee will not be
liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) 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 pursuant to Section 6.05 hereof. 
 (d) Whether or not therein expressly so provided, every provision of this Indenture
that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01. 
 (e) 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 and powers under this Indenture or the Collateral Agreements at the request or direction
of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. 
 (f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers. 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 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. 
 (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. The Trustee may consult with counsel and the written 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 and agents and will not be responsible for the misconduct or negligence of any 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. 
 (e) Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Issuers will be sufficient if signed by an Officer of each of the Issuers. 
  

 72 

 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 Issuers or any Affiliate of
the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest 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, the Notes or the Collateral Agreements, and it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the
Issuers’ 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 known to the Trustee, the Trustee will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of,
premium, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

 Section 7.06 Reports by Trustee to Holders of the Notes. 
 (a) Within 60 days after each August 15 beginning with the August 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee will send 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 set forth 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) and § 313(b)(1). The Trustee will also transmit by mail all reports as required by TIA § 313(c). 
 (b) A copy of each report at the time of its sending to the Holders of Notes will be sent by the Trustee to the Issuers 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 Issuers will promptly notify the Trustee when the Notes are listed on any stock exchange. 
 Section 7.07 Compensation and Indemnity. 
 (a) The Issuers will pay to the Trustee, Collateral Agent, Paying
Agent and Registrar (each, an “Indemnified Party”) from time to time reasonable compensation for their acceptance of this Indenture and the Collateral Agreements 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 Issuers 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 the reasonable compensation, disbursements and expenses of the Indemnified Party’s agents and counsel. 
  

 73 

 (b) The Issuers and the Guarantors will indemnify the 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 Collateral Agreements, including the costs and expenses of enforcing this Indenture against the
Issuers and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any
of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Indemnified Party will notify the Issuers promptly of any claim for which it may
seek indemnity. Failure by the Indemnified Party to so notify the Issuers will not relieve the Issuers or any of the Guarantors of their obligations hereunder or under the Collateral Agreements. The Issuers or such Guarantor will defend the claim
and the Indemnified Party will cooperate in the defense. The Indemnified Party may have separate counsel and the Issuers will pay the reasonable fees and expenses of one such counsel. Neither the Issuers nor any Guarantor need pay for any settlement
made without its consent, which consent will not be unreasonably withheld. 
 (c) The obligations of the Issuers and the Guarantors under
this Section 7.07 will survive the satisfaction and discharge of this Indenture and the termination of the Collateral Agreements. 
 (d)
To secure the Issuers’ and the Guarantors’ payment obligations in this Section 7.07, each Indemnified Party will have a Lien prior to the Notes on all money, property or Collateral 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, premium, if any, and interest on particular Notes pursuant to Article 8 hereof. Such Lien will survive the
satisfaction and discharge of this Indenture. 
 (e) When an Indemnified Party incurs expenses or renders services after an Event of Default
specified in Section 6.01(9) or (10) 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. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 
 Section 7.08 Replacement of Trustee. 
 (a)
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. 
 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof; 
 (2) 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; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
  

 74 

 (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason,
the Issuers 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 Issuers. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Issuers, 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.

 (e) 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. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. 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
Issuers’ 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. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Issuer and the Holders of Notes. Any
such successor must nevertheless be eligible and qualified under the provisions of Section 7.10 hereof. 
 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); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any
indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Company are outstanding, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

 Section 7.11 Preferential Collection of Claims Against Issuers. 
 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. 
  

 75 

 Section 7.12 Trustee in Other Capacities; Collateral Agent and Paying Agent. 
 References to the Trustee in Sections 7.01(b), (d), (f), (g) and (h), 7.02, 7.03, 7.04, 7.07, and 7.08 shall be understood to include the Trustee
when acting in its other capacities under this Indenture, including, without limitation, as Paying Agent and Collateral Agent. Without limiting the foregoing, and for the avoidance of doubt, such Sections shall be read to apply to the Collateral
Agent and the Collateral Agreements, mutatis mutandis, in addition to this Indenture. The privileges, rights, indemnities, immunities and exculpatory provisions contained in this Indenture shall apply to the Trustee, whether it is acting
under this Indenture or the other Indenture Documents. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or
Covenant Defeasance. 
 The Issuers may at any time, at the option of the Board of Directors of a New Parent or the Company, whichever
entity is then the ultimate parent company, 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 Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers 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 in Section 8.04 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 8.06 hereof and the other Sections of this Indenture referred to in clauses
(1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the 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: 
 (1)
the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and interest, premium and Additional Interest, if any, on, such Notes when such payments are due from the trust referred in Section 8.05 hereof;

 (2) the Issuers’ Obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; 
 (3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuers’ and the Guarantors’ obligations in connection therewith; and 
 (4) 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. 
  

 76 

 Section 8.03 Covenant Defeasance. 
 Upon the Issuers’ 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 3.09, 4.08, 4.10 through and including 4.22 and 4.28 hereof; clause
(4) of Section 5.01 hereof and any Liens securing the Notes and the Note Guarantees shall be released 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. 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, the breach or non compliance with the covenants defeased pursuant to this Section 8.03 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: 
 (1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government
Securities, 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, and interest, premium and Additional Interest, if any, on,
the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption
date; 
 (2) in the case of Legal Defeasance, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably
acceptable to the Trustee confirming that (a) the Issuers have 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 will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
 (3) in the case of Covenant Defeasance, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  

 77 

 (4) no Default or Event of Default has occurred and is continuing on the date of such
deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness or the grant of Liens securing such Indebtedness, all or a portion of the proceeds of which will be used to defease the Notes pursuant to this Article 8
concurrently with such incurrence); 
 (5) 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) to which any New Parent, the Company or any of its Subsidiaries is a party or by which any New Parent, the Company or any of its
Subsidiaries is bound; 
 (6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit
was not made by the Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuers or others; 
 (7) the Issuers 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; and 
 (8) concurrently with
the satisfaction of the conditions set forth in this Section 8.04, any Liens securing the Notes or the Note Guarantees shall terminate and be released, and the Trustee, on demand and at the expense of the Issuers, shall execute proper
instruments acknowledging such release. 
 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 (i) held in trust,
(ii) at the written direction of the Issuers, such money may be invested, prior to maturity of the Notes, in Government Securities, and (iii) 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) as the Trustee may determine, 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(1) 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. 
  

 78 

 Section 8.06 Repayment to Company. 
 Subject to any unclaimed property law, 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, 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 or (if then held by the Company) will be
discharged from such trust; and the Holder of such Note will thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or
Government Securities, 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 or The Wall Street Journal, 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 Issuers’ 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 Issuers or any Guarantor make any payment of principal of, premium, 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 or Government Securities 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 hereof, without the consent of any Holder, the Issuers, the Guarantors, the Trustee and, if any amendment or supplement relates to any Collateral Agreement, the Collateral Agent, may amend or supplement

 (1) to cure any ambiguity, defect or
inconsistency;

 79 

 (4) to make any change that would provide any additional rights or benefits to the

 (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; 

(6) to conform the text of this Indenture, the Notes, or the Note Guarantees to any provision of the “Description of Notes”

 (7) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date
(including Section 4.14);

the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of,
or tender offer or exchange offer for, Notes), and any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Collateral Agreements 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, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Section 2.08 hereof shall
determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 
 Without the consent of each
Holder of Notes, an amendment, supplement or waiver may not: 
 (1) reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver;

repurchase payment with respect to any Note (other than a payment required by Sections 4.10 or 4.11 hereof); 
 (8) release
any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; 
 (9) release all or substantially all of the Collateral from the Liens created pursuant to the Collateral Agreements, except in accordance with this Indenture and the Collateral Agreements; or 
 (10) make any change in the preceding amendment and waiver provisions. 
 Section 9.03 Compliance with TIA. 
 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 or
subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation in accordance with Section 13.02 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. 
 The Company may, but shall not be
obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date. 
 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. 
  

 81 

 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. 
 Upon the request of the Issuers, accompanied by a resolution of the Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 or this Section 9.06
hereof, the Trustee shall join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture. 
 It shall
not be necessary for the consent of Holders of Notes under Sections 9.01 or 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.06 becomes effective, the Issuers shall send to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by the
Company with any provision of this Indenture of the Notes. 
 The Trustee will sign any amended 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. In executing any amended 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 amended or supplemental
indenture is authorized or permitted by this Indenture. 
 ARTICLE 10 
 SATISFACTION AND DISCHARGE 
 Section 10.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to all Notes and Note Guarantees issued hereunder and the Trustee, on demand
and at the expense of the Issuers, will execute proper instruments acknowledging satisfaction and discharge of this Indenture, when: 
 (1) either: 
 (a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been
replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Issuers, have been delivered to the Trustee for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the delivering of a
notice of redemption or otherwise or will become due and payable within one year and the Issuers 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 of cash in U.S. dollars and non-callable Government Securities, in 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, interest, premium and Additional Interest, if any, to the date of maturity or redemption; 
  

 82 

 (2) 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 or 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 an Issuer or any Guarantor is a party or by which an Issuer or any Guarantor is bound; 
 (3) the Issuers have or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 
 (4) the Issuers have 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 Issuers 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. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been
deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 10.01, the provisions of Sections 10.02 and 8.06 hereof will survive. In addition, nothing in this Section 10.01 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 10.02 Application
of Trust Money. 
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to
Section 10.01 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 Issuers acting as their own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and 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 10.01 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 Issuers’ and any Guarantor’s
obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 hereof; provided that if the Issuers have made any payment of principal of, premium, if any, or
interest on, any Notes because of the reinstatement of its obligations, the Issuers 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.

 GUARANTEES

 Section 11.01 Guarantee. 
 (a)
Subject to Section 11.02, each of the Guarantors hereby, jointly and severally, unconditionally guarantees on a senior secured basis to the extent, with respect to security, set forth in 

  

 83 

 
Article 12 and the Collateral Agreements, 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 Collateral Agreements or the obligations of the Issuers hereunder or thereunder, that: 
 (1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace
period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders, the Trustee and the Collateral
Agent hereunder or thereunder or under any Collateral Agreement will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, 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. 
 (b)
The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes, this Indenture or any Collateral Agreement, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first
against the Issuers, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder, the Collateral Agent or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian,
trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid by the Issuers or any Guarantor 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. 
 (d) 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 Guarantee. 
  

 84 

 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 Guarantee not constituting a fraudulent transfer or conveyance. 
 Section 11.03 Execution and Delivery of 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 signed by an
Officer of such Guarantor (by manual or facsimile signature) 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 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 Issue Date, if required by
Section 4.20 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.20 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, a Guarantor may not transfer, 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 a New Parent, the Company or another Guarantor, unless: 
 (1) immediately after giving effect to that
transaction, no Default or Event of Default exists; and 
 (2) either: 
  

 85 

 (a) subject to Section 11.05 hereof, the Person acquiring the property in any such
transfer, sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee and the Collateral Agreements pursuant to a supplemental
indenture and an amendment to the Registration Rights Agreement; or 
 (b) the Net Proceeds of such transfer, sale or other
disposition are applied in accordance with the applicable provisions of this Indenture; 
 provided, however, that the transfer, sale or other
disposition of all or substantially all of the assets of, or the consolidation or merger into another person, of a New Parent will be governed by Article 5 hereof and may be subject to 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 and satisfactory in form 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 Issuers 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 2(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 any Issuer, any New Parent 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 any
Issuer, any New Parent or another Guarantor. 
 Section 11.05 Releases. 
 The Note Guarantee of a Guarantor will be released: 
 (1) in connection with any transfer, sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after
giving effect to such transaction) a New Parent, an Issuer or a Restricted Subsidiary of a New Parent or an Issuer, if the transfer, sale or other disposition does not violate Section 4.11 hereof with respect to that Guarantor (other than any
New Parent) and Section 4.10 and Article 5 hereof with respect to any New Parent; 
 (2) in connection with any transfer,
sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) an Issuer or a Restricted Subsidiary of an Issuer, if the sale or other disposition does not
violate Section 4.11 hereof with respect to Guarantors (other than any New Parent) and Section 4.10 and Article 5 hereof with respect to any New Parent; 
 (3) if the Company designates that Guarantor to be an Unrestricted Subsidiary in accordance Section 4.21 hereof; 
  

 86 

 (4) upon Legal Defeasance or Satisfaction and Discharge of this Indenture in Accordance
with Articles 8 and 10 hereof; or 
 (5) as may be provided in any intercreditor agreement we enter into in connection with
any future Credit Facility. 
 Any Guarantor not released from its obligations under its Guarantee as provided in this Section 11.05
will, subject to Section 11.02, remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.

under the Note Guarantees when and as the same shall be due and payable, whether at Stated Maturity thereof, on an Interest Payment Date, by acceleration, purchase, repurchase, redemption or otherwise, and interest on the overdue principal of,

perfected (except as expressly provided herein or therein) security interests in and on all the Collateral, in favor of the Collateral Agent, superior to and prior to the rights of all third Persons, and subject to no other Liens, in each case,
except as expressly permitted herein or therein and shall warrant and defend the title to the Collateral against the claims of all persons whatsoever; 
 (3) shall warrant and defend the title to the Collateral against the claims of all persons, subject to any Intercreditor agreement and any Permitted Liens; and 
 (4) shall do or cause to be done, at their sole cost and expense, all such actions and things as may be necessary or proper, or as may be
required by the provisions of the Collateral Agreements, to assure and confirm to the Collateral Agent the security interests in the Collateral contemplated hereby and by the Collateral Agreements, as from time to time constituted, so as to render

 (1) appoints the Collateral Agent to act as its agent (and by its signature below, the Collateral Agent accepts such appointment); 
  

 87 

 (2) consents and agrees to the terms of each Collateral Agreement, as the same may be in
effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms, and authorizes and directs the Collateral Agent to enter into the Collateral Agreements and to perform its
obligations and exercise its rights thereunder in accordance therewith; and 
 (3) appoints and authorizes the Collateral
Agent and the Trustee to enter into an Intercreditor Agreement with a First Lien Collateral Agent and, as a result thereof acknowledges that any Lien on the Collateral will thereby and at that time become contractually subordinated to any Lien held
by a First Lien Collateral Agent pursuant to the terms of such Intercreditor Agreement as a Lien that shall be prior to any other Lien other than the Lien held by the First Lien Collateral Agent. 
 (c) This Article 12, the Security Agreement and the other Collateral Agreements (other than the Intercreditor Agreement) will be subject to the terms,
limitations and conditions set forth in any Intercreditor Agreement. 
 Section 12.02 Recording and Opinions.

 88 

 Section 12.03 Release of Collateral. 
 (a) The Collateral Agent shall not at any time release Collateral from the security interests created by the Collateral Agreements unless such release is
in accordance with the provisions of this Indenture and the applicable Collateral Agreements. 
 (b) The release of any Collateral from the

circumstances: 
 (1) to enable the Issuer (or a Guarantor) to consummate asset sales and dispositions permitted or not
prohibited under Section 4.11, in each case to a Person other than the Issuers, any New Parent or a Guarantor; provided that such Liens will not be released if such sale or disposition is prohibited by Article 5 or such release would
cause the Issuers to have to comply with section 4.10 and the Issuers are not in compliance therewith;

Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Trustee and the Holders in the Collateral (including the 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 thereunder
or be prejudicial to the interests of the Collateral Agent, the Holders or the Trustee). Notwithstanding the foregoing, the Collateral Agent may, at the expense of the Issuers, request the direction of the Holders with respect to any such actions

 [Back of Note] 
 11% Senior Secured Notes due 2015 
 Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated. 
 (1) INTEREST. Forbes Energy
Services LLC, a Delaware limited liability company and Forbes Energy Capital Inc., a Delaware corporation (collectively, the “Issuers”), promise to pay interest on the principal amount of this Note at a rate of 11% per annum,
from February 12, 2008 until maturity. The Issuers will pay interest semi-annually in arrears on February 15 and August 15 of each year, 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 there is no existing Default
in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof (each, a “Record Date”) 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 August 15, 2008. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal, premium, if any, and interest (without regard to any applicable grace period), from time to time on demand at a rate equal to 2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful. The Issuers
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 Issuers 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 Issuers (or, upon the written request of the Issuers, the Trustee in the
name and at the expense of the Issuers) 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 Issuers will pay Additional Interest, if any,
to Holders of Notes pursuant to the Registration Rights Agreement. Defaulted interest and Additional Interest, if any, will be paid on regular Interest Payment Dates in the same manner as other interest is paid on the Notes. All reference to
“interest” in this Note and the Indenture mean the initial interest rate borne by the Notes and any increases in that rate due to defaulted interest or Additional Interest (unless the Indenture states otherwise). Defaulted interest and
Additional Interest will be in addition to any other interest payable from time to time with respect to the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
 (2) METHOD OF PAYMENT. The Issuers will pay interest on the Notes
(except defaulted interest) to the Persons who are Holders at the close of business on February 1 or August 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 Issuers maintained for such purpose,
or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that (1) payment by wire transfer of immediately available funds will be
required with respect to principal of, interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuers or the Paying Agent and (2) such payment by check
may only be paid so long as no event of default under the Indenture is continuing. 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 

  

 A-4 

 
payment of public and private debts. The principal of the Notes shall be payable only upon surrender of any Note at the specified offices of the Paying
Agent. If the due date for payment of the principal in respect of any Note is not a Business Day at the place in which it is presented for payment, the Holder thereof shall not be entitled to payment of the amount due until the next succeeding
Business Day at such place. 
 (3) PAYING AGENT AND
REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to any
Holder. The Issuers or any of their Subsidiaries may act in any such capacity; provided no Event of Default is continuing. 
 (4) INDENTURE; REGISTRATION RIGHTS AGREEMENT AND COLLATERAL AGREEMENT. The Issuers issued the Notes under an
Indenture dated as of February 12, 2008 (the “Indenture”) among the Issuers, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939, as amended, which applies to the Indenture and is incorporated by reference therein. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act 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 Indenture does not limit the aggregate principal amount of Notes that may be issued
thereunder. Holders are entitled to the benefits of the Registration Rights Agreement and the Collateral Agreements. 
 (5)
RANKING. This Note shall constitute a senior obligation of the Issuers and the Obligations of the Issuers under the Indenture and this Note shall be secured pursuant to the Collateral Documents and will be
subject to the Intercreditor Agreement, if any. 
 (6) OPTIONAL REDEMPTION AND
PURCHASE. The Notes are subject to redemption and purchase as provided in Article III of the Indenture. 
 (7) MANDATORY REDEMPTION. The Issuers are not be required to make mandatory redemption or sinking fund payments with respect to the Notes. 
 (8) REPURCHASE AT THE OPTION OF
HOLDER. 
 (a) If there is a Change of Control, the Issuers will be required to make a
Change of Control Offer to each Holder to repurchase all or any part (equal to minimum amounts of $2,000 and integral multiples of $1,000) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the
“Change of Control Payment”). Within 10 days following any Change of Control or, at the Issuers’ option, prior to such Change of Control but after public announcement thereof, the Issuers will mail a notice to each Holder
setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (b) If the Issuers or a
Restricted Subsidiary of the Issuers consummates an Asset Sale, the Issuers in circumstances specified in the Indenture may be required to commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with
the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets an Asset Sale Offer pursuant to Section 

  

 A-5 

 
3.09 of the Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess
Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the
Indenture. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Issuers prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option
of Holder to Elect Purchase” attached to the Notes. 
 (c) If any New Parent and its Restricted Subsidiaries or the
Company and its Restricted Subsidiaries has Excess Cash Flow for any fiscal year commencing with the fiscal year ending December 31, 2008, each Holder will have the right to require the Issuers to repurchase all or any part of that
Holder’s Notes (in minimum amounts of $2,000 and integral multiples of $1,000) at a purchase price in cash equal to 101% of the principal amount of the Notes repurchased, plus any accrued and unpaid interest and Additional Interest, if any, to
the date of purchase (subject to the rights of Holders of Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date that is on or prior to the date of repurchase), with 50% of Excess Cash Flow of such New Parent
and its Restricted Subsidiaries or the Company and its Restricted Subsidiaries, in each case, on a consolidated basis for such fiscal year (less the amount of any open market purchases and any redemptions of Notes pursuant to the Indenture made
during such fiscal year). 
 (9) NOTICE OF REDEMPTION.
Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed 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 or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000,
unless all of the Notes held by a Holder are to be redeemed. 
 (10) DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Issuers need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (11) PERSONS DEEMED OWNERS. The Holder of a Note may be treated as its
owner for all purposes. Only Holders have rights under the Indenture and this Note. 
 (12) AMENDMENT,
SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a
majority in aggregate principal amount of the then outstanding Notes, voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture, 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, voting as a single class. Without the consent of any Holder of a Note, the Indenture, the Notes or the Note Guarantees may be amended or supplemented
to cure any ambiguity, defect or inconsistency and to effect certain other changes as set forth in the Indenture. 
  

 A-6 

 (13) DEFAULTS AND
REMEDIES. If any 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. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not
enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium, if any,) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by 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 the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Issuers are required to deliver to the Trustee annually
a statement regarding compliance with the Indenture, and the Issuers are required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
 (14) TRUSTEE DEALINGS WITH THE ISSUERS.
The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuers or their Affiliates, and may otherwise deal with the Issuers or their Affiliates, as if it were not the Trustee.

 (15) NO RECOURSE AGAINST OTHERS. No
director, officer, employee, incorporator or equity holder of any New Parent, the Company, Capital or any Guarantor, as such, will have any liability for any obligations of any New Parent, the Company, Capital or the Guarantors under the Notes, the
Indenture or the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. 
 (16) AUTHENTICATION. This Note will not be
valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
 (17)
ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

their control;
