and Citibank, N.A. dated as of June 9, 2005, as amended on February 1, 2010, and as further amended, supplemented or otherwise modified from time to time; provided that any amendment, supplement or modification adverse in any material
respect to the Company or any Restricted Subsidiary shall be permitted under the terms of the Credit Facilities, (ii) the accounts receivable discount sales program solely with respect to the accounts receivable of “the Buyer” (as
identified therein as of the date of this Indenture) established pursuant to the Supplier Agreement between Ducommun Aerostructures New York, Inc. and Citibank, N.A. dated as of November 20, 2009, as further amended, supplemented or otherwise
modified from time to time; provided that any amendment, supplement or modification adverse in any material respect to the Company or any Restricted Subsidiary shall be permitted under the terms of the Credit Facilities, (iii) the accounts

discount sales program permitted under the terms of the Credit Facilities or with terms and pursuant to an agreement in substance substantially similar to those set forth in clauses (i) through (iv) and established in the good faith
business judgment of the Company, in each case as such agreements may be amended, supplemented or otherwise modified from time to time; provided that any amendment, supplement or modification adverse in any material respect to the Company or any
Restricted Subsidiary shall be permitted under the terms of the Credit Facilities. 
 “Additional Assets” means:


  
 1 








 (1) any property, plant, equipment or other long-term tangible or intangible asset used or

Subsidiary described in clause (2) or (3) above is primarily engaged in a Related Business. 
 “Additional
Securities” means Securities issued under this Indenture after the Issue Date and in compliance with Sections 2.13 and 4.03, it being understood that any Securities issued in exchange for or replacement of any Initial Security issued on the
Issue Date shall not be an Additional Security, including any such Securities issued pursuant to a Registration Rights Agreement.

purposes of this definition, “control” when used with respect to any Person means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or
otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. For purposes of Sections 4.04, 4.06 and 4.07 only, “Affiliate” shall also mean any beneficial owner of Capital Stock

Affiliate of any such beneficial owner pursuant to the first sentence hereof. 
 “Applicable Premium” means, with
respect to a Security at any redemption date, as determined by the Company or an agent thereof, the greater of (i) 1.0% of the then outstanding principal amount of such Security at such time and (ii) the excess, if any, of (A) the
present value at such redemption date of (1) the redemption price of such Security on July 15, 2015 (such redemption price being described in the table in the second paragraph of section 5 of the Securities, exclusive of any accrued
interest), plus (2) all required remaining scheduled interest payments due on such Security through July 15, 2015 (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as
of such redemption date plus 50 basis points, over (B) the then outstanding principal amount of such Security on such redemption date. 
 “Asset Disposition” means any sale, lease, transfer or other disposition (or series of related sales, leases, transfers or dispositions) by the Company or any Restricted Subsidiary,
including any disposition by means of a merger, consolidation or similar transaction (each referred to for the purposes of this definition as a “disposition”), of: 

  
 2 








 (1) any shares of Capital Stock of a Restricted Subsidiary (other than directors’
qualifying shares or shares required by applicable law to be held by a Person other than the Company or a Restricted Subsidiary); 
 (2) all or substantially all the assets of any division or line of business of the Company or any Restricted Subsidiary; or 
 (3) any other assets of the Company or any Restricted Subsidiary outside of the ordinary course of business of the Company or such Restricted Subsidiary;

of like property pursuant to Section 1031 of the Code for use in a Related Business; (H) a disposition of assets that are worn-out, obsolete or damaged or no longer used or useful in the business of the Company or any Restricted
Subsidiary, as the case may be, in the ordinary course of business; (I) the licensing or sublicensing of intellectual property or other general intangibles and licenses, sublicenses, leases or subleases of other property in the ordinary course
of business which, in each case, does not materially interfere with the business of the Company and its Restricted Subsidiaries; (J) the disposition of any property or other assets of the Company or any of its Restricted Subsidiaries by reason
of theft, loss, physical destruction or damage, taking or similar event; (K) any surrender or waiver of contract rights or the settlement, release, recovery on or surrender of contract, tort or other claims of any kind; and
(L) foreclosures on assets subject to Liens otherwise permitted to be Incurred by the Company or any of its Restricted Subsidiaries under this Indenture.

annually) of the total obligations of the lessee for rental payments during the remaining term of the lease included in such Sale/Leaseback Transaction (including any period for which such lease has been extended); provided,
however, that if such Sale/Leaseback Transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capital Lease Obligation”. 

“Average Life” means, as of the date of determination, with respect to any Indebtedness, the quotient obtained by dividing
(1) the sum of the products of the numbers of years from the date of determination to the dates of each successive scheduled principal payment of or redemption or similar payment with respect to such Indebtedness multiplied by the amount of
such payment by (2) the sum of all such payments.

thereof duly authorized to act on behalf of such Board. 
 “Business Day” means each day which is not a Legal Holiday.

 “Capital Lease Obligation” means an obligation that is required to be classified and accounted for as a capital

shall be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such lease may be terminated by the lessee without payment of a penalty. For purposes of Section 4.12, a Capital Lease
Obligation will be deemed to be secured by a Lien on the property being leased. 
 “Capital Stock” of any Person means
any and all shares, interests (including partnership interests), rights to purchase, warrants, options, participations or other equivalents of or interests in (however designated) equity of such Person, including any Preferred Stock, but excluding
any debt securities convertible into or exchangeable for such equity. 
 “Captive Insurance Entity” means any Person
(other than an individual) created solely for the purpose of purchasing or providing, or facilitating the provision of, insurance for products liability, workers compensation, property damage, professional indemnity, employee benefits,
employer’s liability and motor and medical expenses, in each case, to the extent that such insurance may be so purchased, provided, or facilitated in accordance with applicable requirements of law. 

“Change of Control” means the occurrence of any of the following events: 

(1) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial
owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that for purposes of this clause (1) such person shall be deemed to have “beneficial ownership” of all shares that any such person has the right to
acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 35% of the total voting power (measured by voting power rather than number of shares) of the Voting Stock of the Company
(including, without limitation, pursuant to a merger or consolidation); 
 (2) individuals who on the Issue Date constituted the
Board of Directors (together with any new directors whose election or appointment by such Board of Directors or whose nomination for election by the shareholders of the Company was approved by a vote of a majority of the directors of the Company
then still in office who were either directors on the Issue Date or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors then in office; 

(3) the adoption of a plan relating to the liquidation or dissolution of the Company; or 

  
 4 








 (4) the merger or consolidation of the Company with or into another Person or the merger of
another Person with or into the Company, or the sale of all or substantially all the assets of the Company (determined on a consolidated basis) to another Person other than a transaction following which (A) in the case of a merger or
consolidation transaction, holders of securities that represented 100% of the Voting Stock of the Company immediately prior to such transaction (or other securities into which such securities are converted as part of such merger or consolidation
transaction) own directly or indirectly at least a majority of the voting power of the Voting Stock of the surviving Person in such merger or consolidation transaction immediately after such transaction and (B) in the case of a sale of assets
transaction, each transferee is or becomes an obligor in respect of the Securities and a Subsidiary of the transferor of such assets. 
 “Code” means the Internal Revenue Code of 1986, as amended. 

“Company” means the party named as such in this Indenture until a successor replaces it and, thereafter, means the successor
and, for purposes of any provision contained herein and required by the TIA, each other obligor on the Securities. 

“Consolidated Coverage Ratio” as of any date of determination means the ratio of 

(a) the aggregate amount of EBITDA for the period ending as of the most recent four consecutive fiscal quarters for which internal
financial statements are available prior to the date of such determination to 
 (b) Consolidated Interest Expense for such four
fiscal quarters; 
 provided, however, that: 
 (1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that remains outstanding or if the transaction giving rise to the need to calculate the
Consolidated Coverage Ratio is an Incurrence of Indebtedness, or both, EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness (including the application of the net
proceeds therefrom) as if such Indebtedness had been Incurred on the first day of such period; 
 (2) if the Company or any
Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged (in each case other than
Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and has not been replaced) on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, EBITDA and
Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary has not earned the interest income actually
earned during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness; 
 (3) if since the beginning of such period the Company or any Restricted Subsidiary shall have made any Asset Disposition, EBITDA for such period shall be reduced by an amount equal to EBITDA (if positive)
directly attributable to the assets which are the subject of such Asset Disposition for such period, or increased by an amount equal to EBITDA (if negative), directly attributable thereto for such period and Consolidated Interest Expense for such
period 

  
 5 








 
shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or
otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense
for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale); 

(4) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment
in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or an acquisition of all of the Capital Stock of a Person or assets, including any acquisition of assets occurring in connection with a transaction requiring a
calculation to be made hereunder, which constitutes all or substantially all of an operating unit or product line of a business or all or substantially all of the assets of the acquired Person, EBITDA and Consolidated Interest Expense for such
period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period; 

(5) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the
Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by
the Company or a Restricted Subsidiary during such period, EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition occurred on the
first day of such period; 
 (6) if since the beginning of such period any Person was designated as an Unrestricted Subsidiary
or redesignated as, or otherwise became, a Restricted Subsidiary, EBITDA and Consolidated Interest Expense shall be calculated on a pro forma basis as if such event had occurred on the first day of such period; and 

(7) if, since the beginning of such period, the Company has classified any of its businesses as discontinued operations, EBITDA and

For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto
and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Company (and
shall include any applicable Pro Forma Cost Savings). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of
determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement has a remaining term in excess of 12 months). If any Indebtedness is
Incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four fiscal quarters subject to the pro forma
calculation to the extent that such Indebtedness was Incurred solely for working capital purposes.

rights, duties or obligations of the Trustee). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibits A and B thereto are part of the terms of this Indenture. 

SECTION 2.02 Execution and Authentication. An Officer shall sign the Securities for the Company by manual or facsimile signature.


  
 29 









 If an Officer whose signature is on a Security no longer holds that office at the time the

includes any additional paying agent. 
 The Company shall enter into an appropriate agency agreement with any Registrar, Paying
Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address
of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned Subsidiary

shall

hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Securities and shall notify the Trustee of
any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee. 

SECTION 2.05 Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five 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 Securityholders. 
 SECTION 2.06 Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security
is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture are met. When Securities are presented to the Registrar or a
co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Securities. Holders will be required to pay all taxes due on transfer. The Company will not be required to transfer or exchange any
Security selected for redemption. Also, the Company will not be required to transfer or exchange any Security for a period of 15 days before a selection of Securities to be redeemed. 

SECTION 2.07 Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims
that the Security has been lost, destroyed or wrongfully taken, the Company, if it determines that the requirements of Section 8-405 of the Uniform Commercial Code are met, shall issue and the Trustee shall authenticate a replacement Security
if the Holder satisfies the requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect itself and in the judgment of the Company to protect
the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge such Holder for their reasonable out-of-pocket expenses in
replacing a Security pursuant to this Section 2.07. 
 Every replacement Security is an additional Obligation of the
Company. 
 SECTION 2.08 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by
the Trustee except for those canceled by it, those delivered to it for cancellation or exchange and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Security (subject to the provisions of Section 2.10). 

  
 31 









 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless
the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser. 

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money
sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.09 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee
shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. 
 SECTION 2.10 Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered
to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of such cancellation to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.10.

 SECTION 2.11 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall
pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Securityholders on a subsequent special record date. The Company
shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Securityholder a notice that states the special record date, the payment date and the amount
of defaulted interest to be paid. 
 SECTION 2.12 CUSIP Numbers. The Company in issuing the Securities may use
“CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers. 

  
 32 









 SECTION 2.13 Issuance of Additional Securities. After the Issue Date, the Company
shall be entitled, subject to its compliance with Section 4.03, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the
date of issuance, first interest payment date and issue price. All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture. 

With respect to any Additional Securities, the Company shall set forth in either (i) a resolution of the Board of Directors and an
Officers’ Certificate or (ii) a supplemental indenture, in each case a copy or copies of which shall be delivered to the Trustee, the following information: 
 (1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.03 that the Company is relying on to issue
such Additional Securities; 
 (2) the issue price, the issue date and the CUSIP number of such Additional Securities;
provided, however, that no Additional Securities may be issued unless such Additional Securities are fungible with the Initial Securities for U.S. federal income tax purposes; and 

(3) whether such Additional Securities shall be Initial Securities or shall be issued in the form of Exchange Securities as set forth in
Exhibit B to the Appendix. 
 ARTICLE 3 
 REDEMPTION 
 SECTION 3.01 Notices to Trustee. If the Company elects to
redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the Trustee in writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption will
occur. 
 The Company shall give each notice to the Trustee provided for in this Section at least 35 days before the
redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions in this
Indenture. 
 SECTION 3.02 Selection of Securities to Be Redeemed. If fewer than all the Securities are to be redeemed,
the Trustee shall select the Securities for redemption on a pro rata basis to the extent practicable, or to the extent not so practicable, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate
(but subject to the requirement that any remaining Securities be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof), unless otherwise required by law or applicable securities exchange or depositary requirements.
The Trustee shall make the selection from outstanding Securities not previously called for redemption. Securities with principal amounts of $2,000 or less shall be redeemed in whole and not in part. The Trustee may select for redemption portions of
the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in minimum denominations of $2,000 principal amount and 

  
 33 









 
integral multiples of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee
shall notify the Company promptly of the Securities or portions of Securities to be redeemed. 
 SECTION 3.03 Notice of
Redemption. At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered
address; provided, however, 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 Securities or a satisfaction and discharge of this Indenture.
Notices of redemption may not be conditional. 
 The notice shall identify the Securities to be redeemed and shall state:

 (1) the redemption date; 
 (2) the redemption price; 
 (3) the name and address of the Paying Agent;

 (4) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price;

 (5) if fewer than all the outstanding Securities are to be redeemed, the identification and principal amounts of the
particular Securities to be redeemed; 
 (6) that, unless the Company defaults in making such redemption payment or the Paying
Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date; and 

(7) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the
Securities. 
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at
the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section 3.03 no later than 10 Business Days prior to the date that notice is to be mailed to the Holders (unless the Trustee
consents to a shorter period). 
 SECTION 3.04 Effect of Notice of Redemption. Once notice of redemption is mailed in
accordance with Section 3.03, Securities called for redemption become due and payable on the redemption date and at the redemption price plus accrued and unpaid interest to the redemption date. Upon surrender to the Paying Agent, such
Securities called for redemption shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related
interest payment date). Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 

  
 34 









 SECTION 3.05 Deposit of Redemption Price. Prior to the redemption date, the Company
shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date
other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation. 
 SECTION 3.06 Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s
expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. 
 SECTION 3.07
Mandatory Redemption. The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Securities. 
 ARTICLE 4 
 COVENANTS 

SECTION 4.01 Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates
and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on or before 10:00 a.m. New York City time on such date the Trustee or the Paying Agent holds in accordance with
this Indenture money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture.

 The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay
interest on overdue installments of interest at the same rate to the extent lawful. 
 SECTION 4.02 SEC Reports. Whether
or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act the Company shall file with the SEC (subject to the next sentence) and provide the Trustee and Holders with such annual reports and other
reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, such reports to be so filed and provided at the times specified for the filings of such reports under such Sections
(including any grace period or extension permitted by the SEC), and containing all the information, audit reports and exhibits required for such reports. The Company will be deemed to have furnished the Trustee and such Holders with such reports if
it has filed such reports with the SEC (and such reports are publicly available), or, if applicable, it complies with the last sentence of this paragraph. If, at any time, the Company is not subject to the periodic reporting requirements of the
Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the preceding sentence with the SEC within the time periods required unless the SEC will not accept such a filing. The Company agrees that it will
not take any action for the purpose of causing the SEC not to accept such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Company will post the reports specified in the preceding sentence on its
website within the time periods that would apply if the Company were required to file those reports with the SEC. 

  
 35 









 At any time that any of the Company’s Subsidiaries are Unrestricted Subsidiaries, then
the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of
operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company. 
 In addition, the Company will furnish to the Holders and to prospective investors, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act so long as the Securities are not freely transferable under the Securities Act. The Company also shall comply with the other provisions of TIA § 314(a). 

SECTION 4.03 Limitation on Indebtedness. 
 (a) The Company will not, and will not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company and the Subsidiary Guarantors
shall be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto on a pro forma basis, the Consolidated Coverage Ratio exceeds 2.0 to 1. 

(b) Notwithstanding the foregoing paragraph (a), the Company and the Restricted Subsidiaries will be entitled to Incur any
or all of the following Indebtedness:

Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) as of any date of Incurrence (after giving pro forma effect to the application of the proceeds of such Incurrence) (with letters of credit
being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed $250.0 million to be reduced on a dollar-for-dollar basis by the aggregate amount of all Net
Available Cash applied by the Company or any Subsidiary Guarantor to repay Indebtedness under Credit Facilities pursuant to Section 4.06; 
 (2) Indebtedness of the Company owed to and held by any Restricted Subsidiary or Indebtedness of a Restricted Subsidiary owed to and held by the Company or any Restricted Subsidiary; provided,
however, that (A) any subsequent issuance or transfer of any Capital Stock that results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of any such Indebtedness (other than to the
Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the obligor thereon; (B) if the Company is the obligor on such Indebtedness, such Indebtedness is and expressly subordinated
to the prior payment in full in cash of all obligations with respect to the Securities; and (C) if a Subsidiary Guarantor is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of
all obligations of such obligor with respect to its Subsidiary Guarantee;

series of related transactions pursuant to which such Subsidiary became a Subsidiary or was acquired by the Company); provided, however, that on the date of such acquisition and after giving pro forma effect thereto, either
(i) the Company would have been able to Incur at least $1.00 of additional Indebtedness pursuant to Section 4.03(a) or (ii) the Consolidated Coverage Ratio of the Company would be greater than the Consolidated Coverage Ratio of the
Company immediately prior to the date of such acquisition; 
 (6) Refinancing Indebtedness in respect of

Restricted Subsidiary of the Company to the extent that the Guaranteed Indebtedness was permitted to be Incurred by another provision of this Section 4.03; provided that if the Indebtedness being Guaranteed is subordinated to or pari
passu with the Securities or the Subsidiary Guarantees, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; 

  
 37 









 (11) Indebtedness Incurred by Foreign Restricted Subsidiaries in an
aggregate principal amount (including all Refinancing Indebtedness Incurred to Refinance any Indebtedness Incurred pursuant to this clause (11)) which, when taken together with all other Indebtedness Incurred pursuant to this clause
(11) and outstanding on the date of such Incurrence, does not exceed $10.0 million; 
 (12) Indebtedness
consisting of customary indemnification, adjustment of purchase price, earn-out or similar obligations of the Company or any Restricted Subsidiary, in each case Incurred in connection with the acquisition or disposition of any assets in accordance

Obligations. 

  
 38 









 (d) For purposes of determining compliance with this Section 4.03:
(1) Indebtedness under Credit Facilities outstanding on the date on which Securities are first issued and authenticated under this Indenture will initially be deemed to have been Incurred on such date in reliance on the exception provided by
Section 4.03(b)(1); and (2) in the event that an item of Indebtedness meets the criteria of more than one of the categories of Indebtedness described in clauses (1) through (16) of Section 4.03(b), or is entitled to be

covenant. 
 (e) For purposes of determining compliance with any restriction on the Incurrence of Indebtedness
where the Indebtedness Incurred is denominated in a currency other than the U.S. dollar, the amount of such Indebtedness will be the U.S. Dollar Equivalent determined on the date of the Incurrence of such Indebtedness; provided,
however, that if any such Indebtedness denominated in a different currency is subject to a Currency Agreement with respect to U.S. dollars covering all principal, premium, if any, and interest payable on such Indebtedness, the amount of such
Indebtedness expressed in U.S. dollars will be as provided in such Currency Agreement. The principal amount of any Refinancing Indebtedness Incurred in the same currency as the foreign currency denominated Indebtedness being Refinanced will be the
U.S. Dollar Equivalent of the Indebtedness Refinanced, except to the extent that such U.S. Dollar Equivalent was determined based on a Currency Agreement, in which case the Refinancing Indebtedness will be determined in accordance with the
preceding sentence. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded solely as a
result of fluctuations in exchange rates or currency values. 
 SECTION 4.04 Limitation on Restricted Payments.

the amount of any cash, or the fair value of any other property, distributed by the Company or a Restricted Subsidiary upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the Net Cash
Proceeds received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding Net Cash Proceeds from sales to a Subsidiary of the Company or to an employee stock ownership plan or to a trust established by the Company
or any of its Subsidiaries for the benefit of their employees); plus

Net Income), in each case received by the Company or any Restricted Subsidiary, and the amount of any cancellation of any guarantee or other contingent obligation constituting an Investment (other than a Permitted Investment), and (ii) to the
extent such Person is an Unrestricted Subsidiary, the portion (proportionate to the Company’s equity interest in such Subsidiary) of the fair market value of the net assets of such Unrestricted Subsidiary at the time such Unrestricted
Subsidiary is designated a Restricted Subsidiary. 
 (b) The provisions of Section 4.04(a) shall not
prohibit: 
 (1) any Restricted Payment made out of the Net Cash Proceeds of the substantially concurrent sale
of, or made by exchange for, Capital Stock of the Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock ownership plan or to a trust established by the Company or any
of its Subsidiaries for the benefit of their employees) or a substantially concurrent cash capital contribution received by the Company from its shareholders; provided, however, that (A) such Restricted Payment shall be
excluded in future calculations of the amount of Restricted Payments and (B) the Net Cash Proceeds from such sale or such cash capital contribution (to the extent so used for such Restricted Payment) shall be excluded from the calculation
of amounts under Section 4.04(a)(3)(B);

any of its Subsidiaries from employees, former employees, directors or former directors of the Company or any of its Subsidiaries (or permitted transferees of such employees, former employees, directors or former directors), pursuant to the terms of
the agreements (including employment agreements) or plans (or amendments thereto) approved by the Board of Directors under which such individuals purchase or sell or are granted the option to purchase or sell, shares of such Capital Stock;

validly tendered and not withdrawn in connection with such Change of Control Offer; provided further, however, that such payments, purchases, redemptions, defeasances or other acquisitions or retirements shall be included in the
calculation of the amount of Restricted Payments; 
 (10) so long as no Default has occurred and is continuing or

all or any portion of the funds or credit support utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company) and outstanding
on such date; 
 (3) any encumbrance or restriction pursuant to an agreement effecting a Refinancing of
Indebtedness Incurred pursuant to an agreement referred to in Section 4.05(1) or this clause (3) or contained in any amendment to an agreement referred to in Section 4.05(1) or this clause (3); provided, however, that
the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such refinancing agreement or amendment are not materially less favorable taken as a whole to the Holders than encumbrances and restrictions with respect
to such Restricted Subsidiary contained in such predecessor agreements as determined by the Company in good faith; 
 (4) any encumbrance or restriction existing under or by reason of provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements,
sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into with the approval of the Company’s Board of Directors if the assets
subject to any such agreement are greater than $1.0 million in the aggregate, which limitation is applicable only to the assets that are the subject of such agreements;

(11) restrictions set forth in agreements governing Indebtedness permitted to be incurred pursuant to Section 4.03(a)
so long as such encumbrances or restrictions are not materially more restrictive, taken as a whole, than those restrictions imposed by this Indenture;

 SECTION 4.06 Limitation on Sales of Assets and Subsidiary Stock. 
 (a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless: 

(1) the Company or such Restricted Subsidiary receives consideration at the time of such Asset Disposition at least equal
to the fair market value (including as to the value of all non-cash consideration) of the shares and assets subject to such Asset Disposition, as determined in good faith by the Company and, if such Asset Disposition involves consideration in excess
of $5.0 million, as evidenced by a resolution of the Board of Directors; 
 (2) at least 75% of the consideration
thereof received by the Company or such Restricted Subsidiary is in the form of cash, Temporary Cash Investments or cash equivalents; and 
 (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be): 

  
 44 









 (A) to prepay, repay, redeem or purchase Indebtedness of the Company or a
Subsidiary Guarantor pursuant to a Credit Facility that is secured by a Lien (in each case other than Indebtedness owed to the Company or an Affiliate of the Company) within one year from the later of the date of such Asset Disposition or the
receipt of such Net Available Cash; 
 (B) to acquire or construct Additional Assets in each case within one
year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash (or to enter into a binding commitment to so acquire or construct Additional Assets so long as such acquisition of construction is effected within
180 days after the date of such commitment); and 
 (C) to make an offer to the Holders (and to holders of other
Senior Indebtedness of the Company or of a Subsidiary Guarantor designated by the Company) to purchase Securities (and such other Senior Indebtedness) pursuant to and subject to the conditions contained in this Indenture; 

provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to clause (A) or
(C) above, the Company or such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or
purchased. 
 Notwithstanding the foregoing provisions of this Section 4.06, the Company and the Restricted Subsidiaries
will not be required to apply any Net Available Cash in accordance with this Section 4.06 except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this
Section 4.06 exceeds $15.0 million. Pending application of Net Available Cash pursuant to this Section 4.06, such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit
Indebtedness. 
 (b) For the purposes of this Section 4.06, the following are deemed to be cash equivalents:

 (1) the assumption of Indebtedness of the Company or of a Subsidiary Guarantor (other than obligations in
respect of Disqualified Stock of the Company) or any Restricted Subsidiary (other than obligations in respect of Disqualified Stock or Preferred Stock of a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary
from all liability on such Indebtedness in connection with such Asset Disposition; and 
 (2) securities received
by the Company or any Restricted Subsidiary from the transferee that are promptly converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion. 

  
 45 









 (c) In the event of an Asset Disposition that requires an offer to purchase
Securities (and other Senior Indebtedness of the Company or of a Subsidiary Guarantor) pursuant to Section 4.06(a)(3)(C) above, the Company shall purchase Securities tendered pursuant to an offer by the Company for the Securities (and
such other Senior Indebtedness) (the “Offer”) at a purchase price of 100% (or at a greater price, in the case of the Securities, in the discretion of the Company) of their principal amount (or, in the event such other Senior
Indebtedness was issued with original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Senior Indebtedness, such lesser price, if any, as may be provided for by
the terms of such Senior Indebtedness) in accordance with the procedures (including prorating in the event of oversubscription) set forth in this Section 4.06; provided that the procedures for making an offer to holders of
other Senior Indebtedness will be as provided for by the terms of such other Senior Indebtedness. If the aggregate purchase price of the Indebtedness tendered pursuant to the Offer exceeds the Net Available Cash allotted to their purchase, the
Company will select the Indebtedness to be purchased on a pro rata basis but in round denominations, which in the case of the Securities will be denominations of $2,000 principal amount or $1,000 multiples in excess thereof. The Company shall not be
required to make such an Offer pursuant to this Section 4.06 unless the Net Available Cash available therefor (after application of such proceeds as provided in clauses (a)(3)(A) and (a)(3)(B) of this Section 4.06 and after
giving effect to any purchases of Securities by the Company made in the open market or otherwise occurring after the date of such Asset Disposition), together with the aggregate Net Available Cash from all previous Asset Dispositions not applied in
accordance with this covenant, exceeds $15.0 million (with any lesser amount being carried forward for purposes of determining whether such an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon
completion of such an Offer, Net Available Cash will be deemed to be reduced by the aggregate amount of such Offer. If any Net Available Cash remains after the completion of any such Offer, the Company may use such Net Available Cash for any purpose
not otherwise prohibited by this Indenture. 
 (d)(1) Promptly, and in any event within 10 days after the Company
becomes obligated to make an Offer, the Company shall deliver to the Trustee and send, by first-class mail to each Holder, a written notice stating that the Holder may elect to have its Securities purchased by the Company either in whole or in part
(subject to prorating as described in Section 4.06(c) in the event the Offer is oversubscribed) in denominations of $2,000 principal amount or $1,000 multiples in excess thereof, at the applicable purchase price. The notice shall
specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such information concerning the business of the Company which the Company in good faith believes
will enable such Holders to make an informed decision (which at a minimum will include (or will incorporate and describe how electronic copies thereof may be accessed) (A) the most recently filed Annual Report on Form 10-K (including audited
consolidated financial statements) of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form 8-K of the Company filed subsequent to such Quarterly Report, other than Current Reports
describing Asset Dispositions otherwise described in the offering materials (or corresponding successor reports), (B) a description of material developments in the Company’s business subsequent to the date of the latest of such Reports,
and (C) if material, appropriate pro forma financial information) and all instructions and materials necessary to tender Securities pursuant to the Offer, together with the information contained in clause (3). 

  
 46 









 (2) Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided above, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to any other Senior Indebtedness
included in the Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (C) the compliance of such allocation with the provisions of Section 4.06(a) and (c).
On such date, the Company shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) in Temporary Cash Investments, maturing on the last Business
Day prior to the Purchase Date or on the Purchase Date if funds are immediately available by open of business, an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section. If the Offer includes other
Senior Indebtedness, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements satisfactory to the Trustee. Upon the expiration of the period for which the Offer remains open (the “Offer
Period”), the Company shall deliver to the Trustee for cancellation the Securities or portions thereof which have been properly tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment
(or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the Securities delivered by the Company to the Trustee is less than the Offer Amount applicable
to the Securities, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with this Section 4.06. 

(3) Holders electing to have a Security purchased shall be required to surrender the Security, with an appropriate form
duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business
Day prior to the Purchase Date, a telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its
election to have such Security purchased. Holders whose Securities are purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered. 

(4) At the time the Company delivers Securities to the Trustee which are to be accepted for purchase, the Company shall
also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section. A Security shall be deemed to have been accepted for purchase at the time the
Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder. 
 (e) The
Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.06. To
the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.06, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 4.06 by virtue of its compliance with such securities laws or regulations. 

  
 47 









 SECTION 4.07 Limitation on Affiliate Transactions. 

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any
transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company (an “Affiliate
Transaction”) unless: 
 (1) the terms of the Affiliate Transaction are no less favorable to the
Company or such Restricted Subsidiary than those that could be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate; 

(2) if such Affiliate Transaction involves an amount in excess of $10.0 million, the terms of the Affiliate Transaction
are set forth in writing and a majority of the non-employee directors of the Company disinterested with respect to such Affiliate Transaction have determined in good faith that the criteria set forth in clause (1) are satisfied and have
approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and 
 (3) if
such Affiliate Transaction involves an amount in excess of $20.0 million, the Board of Directors shall also have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial
standpoint, to the Company and its Restricted Subsidiaries or is not less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was
not an Affiliate. 
 (b) The provisions of Section 4.07(a) shall not prohibit: 

(1) any Investment (including a Permitted Investment) or other Restricted Payment, in each case permitted to be made
pursuant to Section 4.04; 
 (2) any issuance of securities, or other payments, awards or grants in cash,
securities or otherwise pursuant to, or the funding of, employment arrangements, stock options, severance agreements, bonus plans, stock based compensation, employee benefit plans, incentive plans and stock ownership plans approved by the Board of
Directors; 
 (3) loans or advances to employees in the ordinary course of business in accordance with the past
practices of the Company or its Restricted Subsidiaries, but in any event not to exceed $1.0 million in the aggregate outstanding at any one time; 
 (4) the payment of reasonable fees and reimbursements of expenses to directors of the Company and its Restricted Subsidiaries who are not employees of the Company or its Restricted Subsidiaries;


  
 48 









 (5) any transaction with a Restricted Subsidiary or joint venture or similar
entity which would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar entity; 

(6) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company; and 

(7) indemnities of officers, directors and employees of the Company or any Restricted Subsidiaries permitted or required

 SECTION 4.09
Limitation on Sale/Leaseback Transactions. The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property unless: 

(1) the Company or such Restricted Subsidiary would be entitled to (A) Incur Indebtedness in an amount equal to the
Attributable Debt with respect to such Sale/Leaseback Transaction pursuant to Section 4.03 and (B) create a Lien on such property securing such Attributable Debt without equally and ratably securing the Securities pursuant to the covenant
described under Section 4.12; 
 (2) the net proceeds received by the Company or any Restricted Subsidiary
in connection with such Sale/ Leaseback Transaction are at least equal to the fair market value (as determined by the Board of Directors) of such property; and 
 (3) the company applies the proceeds of such transaction in compliance with Section 4.06. 
 SECTION 4.10 Change of Control. 
 (a) Upon the occurrence of
a Change of Control, each Holder shall have the right to require that the Company repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Securities at a purchase price in cash equal to
101 % of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant
interest payment date), in accordance with the terms contemplated in Section 4.10(b). 

  
 49 









 (b) Within 30 days following any Change of Control, the Company shall mail a

the Trustee or the Company receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for
purchase by the Holder and a statement that such Holder is withdrawing his election to have such Security purchased. 
 (d) On the purchase date, all Securities purchased by the Company under this Section shall be delivered by the Company to the Trustee for cancellation, and the Company shall pay the purchase price
plus accrued and unpaid interest, if any, to the Holders entitled thereto.

 However, a Default under clause (4) shall not constitute an Event of Default until the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Securities notify the
Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”.

 The Company shall deliver to the Trustee, within 10 days after becoming aware thereof, written notice in the form of an
Officers’ Certificate of any Event of Default under clauses (3), (5), (8) or (9) and any Default under clause (4), its status and what action the Company is taking or proposes to take with respect thereto. 

  
 54 









 SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default
specified in Section 6.01(6) or (7) with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the outstanding Securities by notice
to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 6.01(6) or (7) with respect to the Company occurs and is continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration
or other act on the part of the Trustee or any Securityholders. The Holders of a majority in aggregate principal amount of the outstanding Securities by notice to the Trustee may rescind any such acceleration with respect to the Securities and its
consequences if (a) the rescission would not conflict with any judgment or decree, (b) all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration
and (c) the Company has paid all other amounts due under this Indenture, including all amounts under Section 7.07. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

SECTION 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder 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. No remedy is exclusive of any other remedy. All available remedies are
cumulative. 
 SECTION 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the
Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences except (a) a Default or Event of Default in the payment of the principal of or interest on a Security, (b) a Default or Event of
Default arising from the failure to redeem or purchase any Security when required pursuant to this Indenture or (c) a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of
each Securityholder affected. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right. 

SECTION 6.05 Control by Majority. The Holders of a majority in aggregate principal amount of the outstanding Securities may direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this
Indenture or is unduly prejudicial to the rights of any other Holder of a Security or that would expose the Trustee to personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that
is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.


  
 55 









 SECTION 6.06 Limitation on Suits. The Trustee shall be under no obligation to
exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense.
Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when due, no Securityholder may pursue any remedy with respect to this Indenture or the Securities 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 outstanding Securities have requested the Trustee to
pursue the remedy; 
 (3) such Holders have offered the Trustee security or indemnity satisfactory to the Trustee
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 outstanding Securities have not given the Trustee a direction inconsistent with the request within such 60-day period. 
 A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. 

SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder. 
 SECTION 6.08 Collection Suit by Trustee. If an
Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together
with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07. 
 SECTION
6.09 Trustee May File Proofs of Claim. The Trustee may 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 and the Securityholders allowed in any judicial
proceedings relative to the Company or any Subsidiary Guarantor, its creditors or its property, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, 

  
 56 









 
disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 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 Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of
the claim of any Holder in any such proceeding. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 

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 for all amounts due under Section 7.07; 

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Securities for principal 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 Securityholders pursuant to this Section. At least 15 days before
such record date, the Company shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid. 
 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 for any action taken or omitted by it as Trustee,
a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, 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 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in principal amount of the Securities. 
 SECTION 6.12 Waiver of Stay or Extension Laws. The
Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force,
which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted. 

  
 57 









 ARTICLE 7 
 TRUSTEE 
 SECTION 7.01 Duties of Trustee. 

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

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

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and
no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the
absence of bad faith 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, in the case of any such certificate or opinion, which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the same to determine whether or not they conform to the
requirements of this Indenture. 
 (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act or its own wilful misconduct, except that: 
 (1) this paragraph shall
not be construed to limit the effect of paragraph (b) of this Section; 
 (2) the Trustee shall not be
liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(3) the Trustee shall 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. 
 (4) No provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of
such funds or adequate indemnity against such risk or liability is not satisfactorily assured to it. 
 (d) The
Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. 
 (e) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

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

  
 58 









 SECTION 7.02 Rights of Trustee. Except as otherwise provided in Section 7.01:

 (a) The Trustee may rely on and shall be protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or 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 shall not be liable for any action it takes or omits to take in the absence of bad faith on its part in reliance on the Officers’ Certificate or Opinion of
Counsel. 
 (c) The Trustee may execute any of the trusts or powers hereunder or act through agents or attorneys
and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care. 

(d) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to
this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

 (e) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this
Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such
request or direction. 
 (f) The Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney.

 (g) Absent receipt of a notice of additional interest as described in paragraph 1 of the Securities, the
Trustee shall be entitled to assume that no additional interest is payable on the immediately succeeding interest payment date. 

SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11. 

  
 59 









 SECTION 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and
makes no representation as to the validity or adequacy of this Indenture, the recitals contained herein or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible
for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s 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 shall mail to each Securityholder notice of the Default or Event of Default within 90 days after it occurs, or, if later, after a Trust Officer of the Trustee has knowledge of such Default or Event of Default, in any case unless such Default
or Event of Default shall have been cured or waived. Except in the case of a Default or Event of Default in payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption provisions of such Security, if
any), the Trustee may withhold the notice and shall be protected in withholding such notice if and so long as a committee of its Trust Officers determines that withholding notice is not opposed to the interests of Securityholders. 

SECTION 7.06 Reports by Trustee to Holders. As promptly as reasonably practicable after each May 15 beginning with the
May 15 following the date of this Indenture the Trustee shall mail to each Securityholder a brief report dated as of May 15 that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). 

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on
which the Securities are listed. The Company agrees to notify promptly the Trustee in writing whenever the Securities become listed on any stock exchange and of any delisting thereof. 

SECTION 7.07 Compensation and Indemnity. The Company shall pay to the Trustee from time to time compensation for its services as
the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all
reasonable expenses, disbursements and advances incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances
of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee for, and hold it harmless against, any and all loss, liability or expense (including attorneys’ fees) incurred by it arising out of or
in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any
of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company
shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee
through the Trustee’s own willful misconduct or negligence. 

  
 60 









 To secure the Company’s payment obligations in this Section, the Trustee shall have a
lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities. 

The Company’s payment obligations pursuant to this Section shall survive the discharge of this Indenture. When the Trustee
incurs expenses after the occurrence of a Default specified in Section 6.01(6) or (7) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law. 

SECTION 7.08 Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in
aggregate principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10; 
 (2) the Trustee is
adjudged bankrupt or insolvent; 
 (3) a receiver or other public officer takes charge of the Trustee or its property; or

 (4) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns, is removed by the Company or by the Holders of a majority in aggregate principal amount of the Securities and
such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to
the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice
of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in aggregate principal amount of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

 Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under
Section 7.07 shall continue for the benefit of the retiring Trustee. 

  
 61 









 SECTION 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

 In case at the time such successor or successors to the Trustee by merger, conversion or consolidation shall succeed to the
trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 

SECTION 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with 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
Company. The Trustee shall comply with 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. 
 ARTICLE 8 
 DISCHARGE OF INDENTURE; DEFEASANCE 
 SECTION 8.01 Discharge of Liability on
Securities; Defeasance. 
 (a) When (1) the Company delivers to the Trustee all outstanding Securities
(other than Securities replaced pursuant to Section 2.07) for cancellation or (2) all outstanding Securities have become due and payable, whether at maturity or on a redemption date as a result of the mailing of a notice of redemption
pursuant to Article 3 hereof or (3) all outstanding Securities shall become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee and, in the case of clauses
(2) and (3) of this Section 8.01, the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Securities, including interest thereon to maturity or such redemption date
(other than Securities replaced pursuant to Section 2.07), and if in any case the Company pays all other sums payable under this Indenture by the Company, then this Indenture shall, subject to Section 8.01(c), cease to be of further
effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company. 

  
 62 









 (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (1) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (2) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.12, the operation
of Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7) and 6.01(8) (but, in the case of Sections 6.01(6) and (7), with respect only to Significant Subsidiaries and Subsidiary Guarantors) and the requirement of the Company to comply with
Section 5.01(a)(3) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. 

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default
with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(4), 6.01(5), 6.01(6), 6.01(7) and 6.01(8) (but, in the case of
Sections 6.01(6) and (7), with respect only to Significant Subsidiaries and Subsidiary Guarantors) or because of the failure of the Company to comply with Section 5.01(a)(3). If the Company exercises its legal defeasance option or its
covenant defeasance option, each Subsidiary Guarantor shall be released from all of its obligations with respect to its Subsidiary Guarantee. 
 Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. 

(c) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05,
2.06, 2.07, 2.08, 7.07 and 7.08 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive. 

SECTION 8.02 Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only
if: 
 (1) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for
the payment of principal of and interest on the Securities to maturity or redemption, as the case may be; 
 (2)
the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government
Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be; 

(3) 90 days pass after the deposit is made and during the 90-day period no Default specified in Sections 6.01(7) or
(8) with respect to the Company occurs which is continuing at the end of the period; 

  
 63 









 (4) the deposit does not constitute a default under any other material
agreement (other than this Indenture) binding on the Company (other than that resulting with respect to the Securities from any borrowing of funds to be applied to make the deposit required to effect such legal defeasance or covenant defeasance and
any similar and simultaneous deposit relating to such Securities, and the granting of Liens in connection therewith); 
 (5) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Securities over the other
creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; 
 (6) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by,
the Internal Revenue Service a ruling, or (B) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that,
the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such 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 defeasance had not occurred; 
 (7) in the case of the covenant defeasance option, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the Securityholders 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; and 
 (8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as
contemplated by this Article 8 have been complied with. 
 Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3. 
 SECTION 8.03
Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the
Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities. 
 SECTION
8.04 Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon written request any excess money or securities held by them at any time. 

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held
by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors. 

  
 64 









 SECTION 8.05 Indemnity for Government Obligations. The Company shall pay and shall
indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 

SECTION 8.06 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in
accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this
Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in
accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. 
 ARTICLE 9 
 AMENDMENTS 

SECTION 9.01 Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the
Securities without notice to or consent of any Securityholder:

inconsistency; 
 (2) to provide for the assumption by a successor Person of the obligations of the Company or
any Subsidiary Guarantor under this Indenture;

 65 









 (8) to conform the text of this Indenture, the Securities or the Subsidiary
Guarantees to any provision of the section of the Offering Circular entitled “Description of the Notes” to the extent that such provision in such section of the Offering Circular was intended to be a substantially verbatim recitation of a
provision of this Indenture, the Securities or the Subsidiary Guarantees, such intention to be evidenced by an Officers’ Certificate of the Company delivered to the Trustee; 

(9) to provide for the issuance of Additional Securities in accordance with the limitations set forth in this Indenture as
of the date of this Indenture; 
 (10) to evidence and provide for the acceptance of the appointment of a
successor Trustee; or 
 (11) to make any amendment to the provisions of this Indenture relating to the form,
authentication, exchange, transfer and legending of Securities; provided, however, that (a) compliance with this Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or any
other applicable securities law and (b) such amendment does not materially affect the rights of Holders to transfer Securities; 
 After an amendment under this Section 9.01 becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The failure to give such notice to all
Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section. 
 SECTION
9.02 With Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities without notice to any Securityholder but with the written consent of the Holders of at least a majority in
aggregate principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities) and any past Default or noncompliance with any provision of this Indenture may also be
waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. However, without the consent of each Holder of an outstanding Security affected thereby, an amendment or waiver may not:

 (1) reduce the amount of Securities whose Holders must consent to an amendment or waiver; 

(2) reduce the rate of or extend the time for payment of interest on any Security; 

(3) reduce the principal of or change the Stated Maturity of any Security; 

(4) change the provisions applicable to the redemption of any Security as described in Article 3 hereof or in Sections 5
and 6 of the Securities; 
 (5) make any Security payable in money other than that stated in the Security;


  
 66 









 (6) impair the right of any Holder to receive payment of principal of and
interest on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities; 

(7) make any changes to Section 6.04 or to clauses (1) through (10) of this Section 9.02; 

(8) make any change in the ranking or priority of any Security that would adversely affect the Holders; 

(9) make any change in, or release other than in accordance with this Indenture, any Subsidiary Guarantee that would
adversely affect the Securityholders; or 
 (10) make any other change in this Section 9.02. 

The consent of the Holders of the Securities is not necessary under this Section 9.02 to approve the particular form of any proposed
amendment. It shall be sufficient if such consent approves the substance of the proposed amendment. 
 After an amendment under
this Section becomes effective, the Company shall mail to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an
amendment under this Section. 
 SECTION 9.03 Compliance with Trust Indenture Act. Every amendment to this Indenture or
the Securities shall comply with the TIA as then in effect. 
 SECTION 9.04 Revocation and Effect of Consents and
Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if
notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the
Trustee. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders
entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be
Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date. 

  
 67 









 SECTION 9.05 Notation on or Exchange of Securities. If an amendment changes the terms
of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or
the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect
the validity of such amendment. 
 SECTION 9.06 Trustee To Sign Amendments. The Trustee shall sign any amendment
authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing any amendment the Trustee shall be entitled
to receive indemnity reasonably satisfactory to it and to receive, and shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

 SECTION 9.07 Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly,
pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such
consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. 

ARTICLE 10 

SUBSIDIARY GUARANTEES 
 SECTION 10.01 Guarantees. Each Subsidiary Guarantor hereby unconditionally and irrevocably Guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns
(a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the
Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed
Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will
remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation. 
 Each Subsidiary
Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities
or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or
any other Person (including any Subsidiary Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any
of the terms or provisions of this Indenture, the Securities or any other agreement; (4) the 

  
 68 









 
release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against
any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such Subsidiary Guarantor. 
 Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives
any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations. 
 Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for
any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or
unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder
or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification thereof, by any default, failure or delay, willful or otherwise, in the performance of
the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary
Guarantor as a matter of law or equity. 
 Each Subsidiary Guarantor further agrees that except as expressly set forth in
Sections 8.01(b), 10.02 and 10.06 its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must
otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
 In
furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on
any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall,
upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest
on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee. 

Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand,
(i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and 

  
 69 









 
(ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall
forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section. 
 Each Subsidiary Guarantor
also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section. 

SECTION 10.02 Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum
aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 
 SECTION 10.03 Successors and Assigns. This Article 10 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of
the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be
vested in such transferee or assignee, all subject to the terms and conditions of this Indenture. 
 SECTION 10.04 No
Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude
any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may
have under this Article 10 at law, in equity, by statute or otherwise. 
 SECTION 10.05 Modification. No modification,
amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the
same, similar or other circumstances. 
 SECTION 10.06 Release of Subsidiary Guarantor. A Subsidiary Guarantor will be
released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.07): 
 (1) upon the sale (including any sale pursuant to any exercise of remedies by a holder of Indebtedness of the Company or of such Subsidiary Guarantor) or other disposition (including by way of
consolidation or merger) of a Subsidiary Guarantor; 

  
 70 









 (2) upon the sale or disposition of all or substantially all the assets of
such Subsidiary Guarantor; 
 (3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary
in accordance with the terms of this Indenture; 
 (4) at such time as such Subsidiary Guarantor does not have
any Obligations outstanding that required such Subsidiary Guarantor to enter into a Guarantee Agreement pursuant to Section 4.11, and the Company provides an Officers’ Certificate to the Trustee certifying that no such Indebtedness is
outstanding and that the Company elects to have such Subsidiary Guarantor released; or 
 (5) upon defeasance of
the Securities or discharge of this Indenture pursuant to Article 8; 
 provided, however, that in the case of clauses
(1) and (2) above, (i) such sale or other disposition is made to a Person other than the Company or a Subsidiary of the Company, (ii) such sale or disposition is otherwise permitted by this Indenture and (iii) the Company
provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.06. At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing
such release. 
 SECTION 10.07 Contribution. Each Subsidiary Guarantor that makes a payment under its Subsidiary
Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment
based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

 2. The Securities 
 2.1 (a) Form and Dating. The Initial Securities will be offered and sold by the Company pursuant to a Purchase Agreement. The Initial Securities will be resold initially only to (i) QIBs
in reliance on Rule 144A under the Securities Act (“Rule 144A”) and (ii) Persons other than U.S. Persons (as defined in Regulation S) in reliance on Regulation S under the Securities Act (“Regulation S”).
Initial Securities may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S, subject to the restrictions on transfer set forth herein. Initial Securities initially resold pursuant to Rule 144A shall be
issued initially in the form of one or more permanent global Securities in fully registered form (collectively, the “Rule 144A Global Security”), and Initial Securities initially resold pursuant to Regulation S shall be issued
initially in the form of one or more global securities in fully registered form (collectively, the “Regulation S Global Security”), in each case without interest coupons and with the global securities legend and the applicable restricted
securities legend set forth in Exhibit A hereto, which shall be deposited on behalf of the purchasers of the Initial Securities represented thereby with the Securities Custodian and registered in the name of the Depository or a nominee of the
Depository, duly executed by the Company and authenticated by the Trustee as provided in this Indenture. Through the Distribution Compliance Period, beneficial interests in the Regulation S Global Security may be held only through the Euroclear
System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) (as indirect participants in DTC), unless transferred to a person that takes delivery through a Rule 144A Global Security in accordance with the certification
requirements described below. 
 Prior to and after the expiration of the Distribution Compliance Period, beneficial interests
in the Regulation S Global Securities may be exchanged for beneficial interests in the Rule 144A Global Securities only if: 

(1) such exchange occurs in connection with a transfer of the Initial Securities pursuant to Rule 144A; and 

(2) the transferor first delivers to the Trustee a written certificate (in the form set forth on the reverse of the Security) to the
effect that the Initial Securities are being transferred to a Person: 
 (a) who the transferor reasonably
believes to be a qualified institutional buyer within the meaning of Rule 144A; 
 (b) purchasing for its own
account or the account of a qualified institutional buyer in a transaction meeting the requirements of Rule 144A; and 
 (c) in accordance with all applicable securities laws of the states of the United States and other jurisdictions. 
 Beneficial interests in a Rule 144A Global Note may be transferred to a Person who takes delivery in the form of an interest in the Regulation S Global Note, whether before or after the expiration of the
Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form set forth on the reverse of the Security) to the effect that 

  
 3 








 
such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available) and that, if such transfer occurs prior to the expiration of the Distribution Compliance
Period, the interest transferred will be held immediately thereafter through Euroclear or Clearstream. 
 The aggregate
principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter provided. 

(b) Book-Entry Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the
Depository. 
 The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate and
deliver initially one or more Global Securities that (a) shall be registered in the name of the Depository for such Global Security or Global Securities or the nominee of such Depository and (b) shall be delivered by the Trustee to such
Depository or pursuant to such Depository’s instructions or held by the Trustee as custodian for the Depository. 
 Members
of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee as the custodian of the Depository or
under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its
Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Security. 
 (c) Definitive Securities. Except as provided in this Section 2.1 or Section 2.3 or 2.4, owners of beneficial interests in Global Securities shall not be entitled to receive physical
delivery of Definitive Securities. 
 2.2 Authentication 

The Trustee shall authenticate and deliver: (1) on the Issue Date, an aggregate principal amount of $200,000,000 9.750% Senior Notes
due 2018, (2) any Additional Securities for an original issue in an aggregate principal amount specified in the written order of the Company pursuant to Section 2.02 of this Indenture and (3) Exchange Securities or Private Exchange
Securities for issue only in a Registered Exchange Offer or a Private Exchange, respectively, pursuant to a Registration Rights Agreement, for a like principal amount of Initial Securities, in each case upon a written order of the Company signed by
an Officer of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of any issuance of Additional Securities pursuant to
Section 2.13 of this Indenture, shall certify that such issuance is in compliance with Section 4.03 of this Indenture.

 (x) to register the transfer of such Definitive Securities; or 

(y) to exchange such Definitive Securities for an equal principal amount of Definitive Securities of other authorized denominations,

 the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such
transaction are met; provided, however, that the Definitive Securities surrendered for transfer or exchange: 

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the
Registrar, duly executed by the Holder thereof or its attorney duly authorized in writing; and 
 (ii) if such Definitive
Securities are required to bear a restricted securities legend, they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A),
(B) or (C) below, and are accompanied by the following additional information and documents, as applicable: 
 (A) if
such Definitive Securities are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or 

(B) if such Definitive Securities are being transferred to the Company, a certification to that effect; or 

(C) if such Definitive Securities are being transferred (x) pursuant to an exemption from registration in accordance with
Rule 144A, Regulation S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (i) a certification to that effect (in the form set forth on the reverse of the
Security) and (ii) if the Company so requests, an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in Section 2.3(e)(i). 

(b) Restrictions on Transfer of a Definitive Security for a Beneficial Interest in a Global Security. A Definitive Security may
not be exchanged for a beneficial interest in a Rule 144A Global Security or a Regulation S Global Security except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Definitive Security, duly endorsed or
accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: 
 (i) certification, in
the form set forth on the reverse of the Security, that such Definitive Security is either (A) being transferred in accordance with Rule 144A or (B) is being transferred in accordance with Rule 903 or Rule 904 under Regulation S; and


  
 5 








 (ii) written instructions directing the Trustee to make, or to direct the Securities
Custodian to make, an adjustment on its books and records with respect to such Rule 144A Global Security (in the case of a transfer pursuant to clause (b)(i)(A)) or Regulation S Global Security (in the case of a transfer pursuant to clause
(b)(i)(B)) to reflect an increase in the aggregate principal amount of the Securities represented by the Rule 144A Global Security or Regulation S Global Security, as applicable, such instructions to contain information regarding the
Depository account to be credited with such increase, then the Trustee shall cancel such Definitive Security and cause, or direct the Securities Custodian to cause, in accordance with the standing instructions and procedures existing between the
Depository and the Securities Custodian, the aggregate principal amount of Securities represented by the Rule 144A Global Security or Regulation S Global Security, as applicable, to be increased by the aggregate principal amount of the
Definitive Security to be exchanged and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Rule 144A Global Security or Regulation S Global Security, as applicable,
equal to the principal amount of the Definitive Security so canceled. If no Rule 144A Global Securities or Regulation S Global Securities, as applicable, are then outstanding, the Company shall issue and the Trustee shall authenticate, upon a
written order of the Company signed by an Officer of the Company, a new Rule 144A Global Security or Regulation S Global Security, as applicable, in the appropriate principal amount. 

(c) Transfer and Exchange of Global Securities. 
 (i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depository, in accordance with this Indenture (including applicable restrictions on
transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor of a beneficial interest in a Global Security shall deliver to the Registrar a written order given in accordance with the Depository’s
procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Security. The Registrar shall, in accordance with such instructions, instruct the Depository to credit to
the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer the beneficial interest in the Global Security being transferred. 

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global
Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so
transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred. 

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security
may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository. 

  
 6 








 (iv) In the event that a Global Security is exchanged for Definitive Securities pursuant to
Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such
procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Securities intended to ensure that such transfers comply with Rule 144A,
Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company. 
 (d) Legend. 
 (i) Except as permitted by the following paragraphs (ii),
(iii) and (iv), each Security certificate evidencing the Global Securities (and all Securities issued in exchange therefor or in substitution thereof), in the case of Securities offered otherwise than in reliance on Regulation S, shall bear a
legend in substantially the following form: 
 THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT
FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION
THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE ISSUER THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE
TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II)
OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (IV) PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (V) TO AN ACCREDITED INVESTOR WITHIN THE MEANING OF RULE 501(A)(1), (2), (3), (4) OR (7) OF REGULATION D UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH
(V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED
TO IN (A) ABOVE. 

  
 7 








 Each certificate evidencing a Security offered in reliance on Regulation S shall, in lieu of
the foregoing, bear a legend in substantially the following form: 
 THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN
A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT
PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT. 

Each Definitive Security shall also bear the following additional legend: 

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR SUCH CERTIFICATES AND OTHER INFORMATION AS MAY BE REQUIRED BY
THE INDENTURE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS. 
 (ii) Upon any sale or transfer of a
Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer
Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such
sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security). 
 (iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial
Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such
Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case
without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Private Exchange
Security or directions to transfer such Holder’s interest in the Global Security, as applicable. 

  
 8 








 (iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial
Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial
Securities, and Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit A hereto will be available to Holders that exchange such Initial Securities in such Registered
Exchange Offer. 
 (v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements
pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange
Securities in global form with the global securities legend and the applicable restricted securities legend set forth in Exhibit A hereto will be available to Holders that exchange such Initial Securities in such Private Exchange. 

(e) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been
exchanged for Definitive Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial
interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records
of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction. 

(f) No Obligation of the Trustee. 
 (i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the
records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the
Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under
the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only
through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any
beneficial owners. 

  
 9 








 (ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial
owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof. 
 2.4 Definitive Securities

 (a) A Global Security deposited with the Depository or with the Trustee as Securities Custodian for the Depository pursuant
to Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 hereof and (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a “clearing
agency” registered under the Exchange Act and, in either case, a successor Depository is not appointed by the Company within 90 days of such notice, or (ii) an Event of Default has occurred and is continuing and the Depository requests the
Company to issue Definitive Securities or (iii) the Company, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under this Indenture. 

(b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by
the Depository to the Trustee located at its corporate trust office, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global
Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered only in minimum
denominations of $ 2,000 principal amount and any integral multiples of $1,000 in excess thereof and registered in such names as the Depository shall direct. Any Definitive Security delivered in exchange for an interest in the Transfer Restricted
Security shall, except as otherwise provided by Section 2.3(e) hereof, bear the applicable restricted securities legend and definitive note legend set forth in Exhibit A hereto. 

(c) Subject to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Security shall be entitled to grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Company shall promptly make
available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons.

 [FORM OF REVERSE SIDE OF INITIAL SECURITY] 

9.750% Senior Note due 2018 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

 

	 	1.	Interest 

 Ducommun
Incorporated, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at
the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.50% per annum
(increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which
any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. Not less than 15 days (or such other shorter period of time acceptable to the Trustee) prior to each interest payment date, the
Company shall deliver notice to the Trustee of any Registration Default, the rate of any additional interest and the amount of any additional interest payable on such interest payment date. The Company will pay interest semiannually on July 15
and January 15 of each year, commencing January 15, 2012. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 28, 2011. Interest will be computed
on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.00% per annum, and it will pay interest on overdue installments of interest at the same rate to
the extent lawful. 
  

	 	2.	Method of Payment 

 The
Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the July 1 or January 1 immediately preceding the interest payment date even
if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States
that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately
available funds to the accounts specified by the Depository. The Company will make all payments in respect of a Definitive Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof;
provided, however, that payments on a Definitive Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 

  
 5 









	 	3.	Paying Agent and Registrar 


Initially, Wilmington Trust FSB (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar. 

 

	 	4.	Indenture 

 The Company
issued the Securities under an Indenture dated as of June 28, 2011 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb), as amended (the “Act”), as in effect on the date of the Indenture. Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. To the extent any provision of the Securities conflict
with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 
 The Securities
are general unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities
issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that
limit the ability of the Company and its Subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; issue or sell capital stock of Subsidiaries; engage in transactions
with affiliates; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of Subsidiaries; and consolidate, merge or transfer all or substantially all of its assets and the assets of its Subsidiaries. These covenants are

	 	13.	Amendment, Waiver 


Subject to certain exceptions set forth in the Indenture (a) the Indenture and the Securities may be amended with the written consent
of the Holders of at least a majority in aggregate principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal
amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee shall be entitled to amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect

Under the Indenture, Events of Default include (a) a default in the payment of interest, if any, on the Securities when due,
continued for 30 days; (b) a default in the payment of principal of, or premium, if any, on, any Security when due at its Stated Maturity, upon optional redemption, upon required purchase, upon declaration of acceleration or otherwise;
(c) the failure by the Company to comply with its obligations under Section 5.01 of the Indenture; (d) the failure by the Company or any Subsidiary Guarantor to comply for 60 days (or 90 days in the case of Section 4.02 of the
Indenture) after notice with its other agreements contained in the Indenture; (e) Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable grace period after final maturity or is
accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25.0 million; (f) certain events of bankruptcy, insolvency or reorganization of the Company, a Subsidiary Guarantor
or any Significant Subsidiary; (g) any judgment or decree for the payment of money in excess of $25.0 million (net of any amounts insured by a solvent third party that has not disclaimed coverage) is entered against the Company, a Subsidiary
Guarantor or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following such judgment and is not discharged, waived or stayed; and (h) any Subsidiary Guarantee ceases to be in full force and effect (other than
in accordance with the terms of such Subsidiary Guarantee and the Indenture) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee. If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and
payable immediately upon the occurrence of such Events of Default. 
 Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in aggregate
principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it
determines that withholding notice is not opposed to the interest of the Holders.

	 	15.	Trustee Dealings with the Company 

 Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and
collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

 

	 	16.	No Recourse Against Others 


A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Securities. 
  

	 	17.	Authentication

Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed

 9.750%
Senior Note due 2018 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below
unless otherwise indicated. 
  

	 	1.	Interest 

 Ducommun
Incorporated, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at
the rate per annum shown above[; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.50% per annum
(increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which
any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. Not less than 15 days (or such other shorter period of time acceptable to the Trustee) prior to each interest payment date, the
Company shall deliver notice to the Trustee of any Registration Default, the rate of any additional interest and the amount of any additional interest payable on such interest payment date.]4 The Company will pay interest semiannually on July 15 and January 15 of each year, commencing
January 15, 2012. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 28, 2011. Interest will be computed on the basis of a 360-day year of twelve
30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.00% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful. 

 

	 	2.	Method of Payment 

 The
Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the July 1 or January 1 immediately preceding the interest payment date even
if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States
that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately
available funds to the accounts specified by the Depository. The Company will make all payments in respect of a Definitive Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof;
provided, however, that payments on a Definitive Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a

bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days
immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  

	 	3.	Paying Agent and Registrar

issued the Securities under an Indenture dated as of June 28, 2011 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb), as amended (the “Act”), as amended, as in effect on the date of the Indenture. Terms defined in the Indenture and
not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. To the extent any provision of the
Securities conflict with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all
purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its Subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments;
issue or sell capital stock of Subsidiaries; engage in transactions with affiliates; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of Subsidiaries; and consolidate, merge or transfer all or substantially all

to accrue on the Securities or portions thereof called for redemption on the applicable redemption date.

foregoing, the Company may at any time and from time to time purchase Securities in the open market or otherwise.

 The Securities are in registered form without coupons in denominations of $2,000 principal amount and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Securities in
accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not
register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection
of Securities to be redeemed or 15 days before an interest payment date. 
  

	 	10.	Persons Deemed Owners 


The registered Holder of this Security may be treated as the owner of it for all purposes. 

 

	 	11.	Unclaimed Money 

 If money
for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders
entitled to the money must look only to the Company and not to the Trustee or Paying Agent for payment. 
  

	 	12.	Discharge and Defeasance 


Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities
and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 

 

	 	13.	Amendment, Waiver 


Subject to certain exceptions set forth in the Indenture (a) the Indenture and the Securities may be amended with the written consent
of the Holders of at least a majority in aggregate principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal
amount outstanding of the Securities. Subject to certain exceptions set forth in the 

  
 7 








 
Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities, including
Subsidiary Guarantees, or to secure the Securities, or to add to the covenants of, or surrender rights and powers conferred on, the Company or the Subsidiary Guarantors, or to comply with any requirement of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that would provide additional rights or benefits to the Holders or that does not adversely affect the rights of any Securityholder, or to provide for the issuance of Additional Securities in accordance
with the limitations set forth in the Indenture, or to evidence and provide for the acceptance of the appointment of a successor trustee, or to make amendments to provisions of the Indenture relating to the form, authentication, transfer and
legending of the Securities, or to conform the text of the Indenture, the Securities of the Subsidiary Guarantees to any provision in the section of the Offering Circular entitled “Description of the Notes” to the extent that such
provision in such section was intended to be a verbatim recitation of a provision of the Indenture, the Securities or the Subsidiary Guarantees. 
  

	 	14.	Defaults and Remedies 


Under the Indenture, Events of Default include (a) a default in the payment of interest, if any, on the Securities when due,
continued for 30 days; (b) a default in the payment of principal of, or premium, if any, on, any Security when due at its Stated Maturity, upon optional redemption, upon required purchase, upon declaration of acceleration or otherwise;
(c) the failure by the Company to comply with its obligations under Section 5.01 of the Indenture; (d) the failure by the Company or any Subsidiary Guarantor to comply for 60 days (or 90 days in the case of Section 4.02 of the
Indenture) after notice with its other agreements contained in the Indenture; (e) Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable grace period after final maturity or is
accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25.0 million; (f) certain events of bankruptcy, insolvency or reorganization of the Company, a Subsidiary Guarantor
or any Significant Subsidiary; (g) any judgment or decree for the payment of money in excess of $25.0 million (net of any amounts insured by a solvent third party that has not disclaimed coverage) is entered against the Company, a Subsidiary
Guarantor or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following such judgment and is not discharged, waived or stayed; and (h) any Subsidiary Guarantee ceases to be in full force and effect (other than
in accordance with the terms of such Subsidiary Guarantee and the Indenture) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee. If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and
payable immediately upon the occurrence of such Events of Default. 
 Securityholders may not enforce the Indenture or the
Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in


  
 8 








 
aggregate principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a
Default in payment of principal or interest) if it determines that withholding notice is not opposed to the interest of the Holders. 
  

	 	15.	Trustee Dealings with the Company 

 Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and
collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

 

	 	16.	No Recourse Against Others 


A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Securities. 
  

	 	17.	Authentication 

 This
Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.
