 Section 2.03. Registrar, Paying Agent and Authenticating Agent; Paying Agent to Hold Money in
Trust. (a) The Company may appoint one or more Registrars and one or more Paying Agents, and the Trustee may appoint an Authenticating Agent, in which case each reference in the Indenture to the Trustee in respect of the
obligations of the Trustee to be performed by that Agent will be deemed to be references to the Agent. The Company may act as Registrar or (except for purposes of Article 8) Paying Agent. In each case the Company and the Trustee will enter
into an appropriate agreement with the Agent implementing the provisions of the Indenture relating to the obligations of the Trustee to be performed by the Agent and the related rights. The Company initially appoints the Trustee as Registrar
and Paying Agent. 
 (b) The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will
hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of and interest on the Notes and will promptly notify the Trustee of any default by the Company in making any such
payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment default, upon written request to a
Paying Agent, require the Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no further liability for the money so paid over to the Trustee. 

Section 2.04. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if a Holder claims that its Note has
been lost, destroyed or wrongfully taken, the Company will issue and the Trustee will authenticate a replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. Every replacement Note is an
additional obligation of the Company and entitled to the benefits of the Indenture. If required by the Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the
Company and the Trustee from any loss they may suffer if a Note is replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Note. In case the mutilated, lost, destroyed or wrongfully taken
Note has become or is about to become due and payable, the Company in its discretion may pay the Note instead of issuing a replacement Note. 

Section 2.05. Outstanding Notes. (a) Notes outstanding at any time are all Notes that have been authenticated by the
Trustee except for 
 (1) Notes cancelled by the Trustee or delivered to it for cancellation; 

(2) any Note which has been replaced pursuant to Section 2.04 unless and until the Trustee and the Company receive proof
satisfactory to them that the replaced Note is held by a bona fide purchaser; and 
 (3) on or after the
Stated Maturity or any redemption date or date for purchase of the Notes pursuant to an Offer to Purchase, those Notes payable or to be redeemed or purchased on that date for which the Trustee (or Paying Agent, other than the Company or an Affiliate
of the Company) holds money sufficient to pay all amounts due on such date. 

  
 19 








 (b) A Note does not cease to be outstanding because the Company or one of its Affiliates holds
the Note, provided that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given or taken any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Notes
owned by the Company or any Affiliate of the Company will be disregarded and deemed not to be outstanding, (it being understood that in determining whether the Trustee is protected in relying upon any such request, demand, authorization, direction,
notice, consent, waiver or other action, only Notes which the Trustee knows to be so owned will be so disregarded). Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of
the Trustee the pledgee’s right so to act with respect to such Notes and that the pledgee is not the Company or any Affiliate of the Company. 

Section 2.06. Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee will
authenticate temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have insertions, substitutions, omissions and other variations determined to be appropriate by the Officer executing the temporary
Notes, as evidenced by the execution of the temporary Notes. If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes
will be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for the purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender for cancellation of any
temporary Notes the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes will be entitled to the
same benefits under the Indenture as definitive Notes. 
 Section 2.07. Cancellation. The Company at any time may deliver
to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder
which the Company has not issued and sold. Any Registrar or the Paying Agent will forward to the Trustee any Notes surrendered to it for transfer, exchange or payment. The Trustee will cancel all Notes surrendered for transfer, exchange,
payment or cancellation and dispose of them in accordance with its normal procedures or the written instructions of the Company. Certification of the destruction of all cancelled Notes will be delivered to the Company. The Company may not
issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation. 

  
 20 








 Section 2.08. CUSIP and CINS Numbers. The Company in issuing the Notes may use
“CUSIP” and “CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders, the notice to state that no representation is made as
to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly notify the Trustee of any change in the CUSIP or CINS numbers. 

Section 2.09. Registration, Transfer and Exchange. (a) The Notes will be issued in registered form only, without coupons,
and the Company shall cause the Trustee to maintain a register (the “Register”) of the Notes, for registering the record ownership of the Notes by the Holders and transfers and exchanges of the Notes. 

(b) (1) Each Global Note will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the
Depositary thereof, will bear the DTC Legend. 
 (2) Each Global Note will be delivered to the Trustee as custodian for the
Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (1) as set forth in Section
2.09(b)(4) and (2) transfers of portions thereof in the form of Certificated Notes may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary
in accordance with customary procedures of the Depositary and in compliance with this Section. 
 (3) Agent Members will
have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of
such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global
Note through an Agent Member) to take any action which a Holder is entitled to take under the Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any security. 
 (4) If (x) the Depositary notifies the Company that it is unwilling
or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee has received a request from the
Depositary, the Trustee will promptly exchange each beneficial interest in the Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such
beneficial interest, as identified to the Trustee by the Depositary, and thereupon the Global Note will be deemed canceled. 

  
 21 








 (c) Each Certificated Note will be registered in the name of the holder thereof or its nominee.

 (d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest
therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange. The Trustee will promptly register any transfer or
exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that 

(x) no transfer or exchange will be effective until it is registered in such register and 

(y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Note for a period of 15 days
before a selection of Notes to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption
or purchase, that portion of any Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to
register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name
the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary. 

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration
of a transfer or exchange in accordance with this Section. 
 No service charge will be imposed in connection with any transfer or exchange
of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange
pursuant to subsection (b)(4)). 
 (e) (1) Global Note to Global Note. If a beneficial interest in a Global Note
is transferred or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or
exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a 

  
 22 








 
Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such
Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long
as it remains such an interest. 
 (2) Global Note to Certificated Note. If a beneficial interest in a Global
Note is transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated
Notes in authorized denominations having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as
applicable. 
 (3) Certificated Note to Global Note. If a Certificated Note is transferred or exchanged for a
beneficial interest in a Global Note, the Trustee will (x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (z) in the event that such
transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the
untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof. 
 (4)
Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new
Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case
of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more
Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

(c) Once notice of redemption is sent to the Holders, Notes called for redemption become due and payable at the redemption price on the
redemption date, and upon surrender of the Notes called for redemption, the Company shall redeem such Notes at the redemption price. Commencing on the redemption date, Notes redeemed will cease to accrue interest. Upon surrender of any Note

initially designates the office of U.S. Bank National Association, as such office or agency of the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address
of the Trustee set forth in Section 12.03. 
 The Company may also from time to time designate one or more other offices or agencies where
the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an
office or agency in the United States of America for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Subsidiaries taken as a whole.

Company and any of its Subsidiaries in respect of Sale and Leaseback Transactions (with the exception of such transactions which are

 Section 4.08. Limitation On Sale and Leaseback Transactions. The Company will not, and will not permit any of
its Subsidiaries to, enter into any Sale and Leaseback Transaction unless: 
 (1) the Sale and Leaseback Transaction is
solely with the Company or any of its Subsidiaries; 
 (2) the lease is for a period not in excess of 24 months, including

(5) the Attributable Debt of the Company and its Subsidiary in respect of such Sale and Leaseback Transaction and all other

duplication) of (x) Indebtedness secured by Liens then outstanding (not including any such Indebtedness secured by Liens described in clauses (1) through (9) of Section 4.06(a)) which do not equally and ratably secure the Notes (or secure Notes on a
basis that is prior to other Indebtedness secured thereby) and (y) Non-Guarantor Subsidiary Debt (with the exception of Non-Guarantor Subsidiary Debt which is described in clauses (1) through (6) of Section 4.07(a)), would not exceed an amount equal
to (x) 15% of Consolidated Net Tangible Assets less (y) the aggregate principal amount of the Initial Notes outstanding at such time and the amount of (i) any Indebtedness incurred to extend, renew, replace or refund such Initial Notes secured by
Liens pursuant to Section 4.06(a)(8), (ii) any Indebtedness incurred pursuant to Section 4.06(a)(8) to refinance Indebtedness

Additional Refinancing Amount). 
 Section 4.09. Limitation on Notes Collateral Asset Sales. (a) The Parent Guarantor
will not, and will not permit any Restricted Subsidiary to, make any Notes Collateral Asset Sale unless the following conditions are met: 

(1) The Notes Collateral Asset Sale is for at least fair market value (such fair market value to be determined on the date of
contractually agreeing to such asset sale), as determined in good faith by the Board of Directors. 
 (2) At least 75% of the
consideration consists of cash or Cash Equivalents or assets described in clause (3) below of the type constituting Notes Collateral received at closing; provided, however, the non-cash consideration received is pledged as Notes
Collateral under the Security Documents substantially simultaneously with such sale, in accordance with the requirements set forth in the Indenture. For purposes of this clause (2), (a) the assumption by the purchaser of Indebtedness or other
obligations (other than Subordinated Indebtedness) of the Company or a Guarantor pursuant to a customary novation agreement and (b) instruments or securities received from the purchaser that are promptly, but in any event within 90 days of the
closing, converted by the Company or a Guarantor to cash, to the extent of the cash actually so received, shall be considered cash received at closing). 

(3) Within 365 days after the receipt of any Net Cash Proceeds from a Notes Collateral Asset Sale, the Net Cash Proceeds may be
used (x) to acquire all or substantially all of the assets of a Permitted Business or a majority of the Voting Stock of another Person that thereupon becomes a Restricted Subsidiary engaged in a Permitted Business, (y) to make capital expenditures
or otherwise acquire long-term assets that are to be used in a Permitted Business; provided that any assets acquired pursuant to subclauses (x) or (y) of a type constituting Notes Collateral are pledged as Notes Collateral under the Security
Documents substantially simultaneously with such acquisition in accordance with the requirements of the Indenture, or (z) to repay Parity Lien Obligations; provided that if the Company shall so reduce Parity Lien Obligations pursuant to this
clause (3), the Company will equally and ratably reduce Obligations under the Notes as provided under Section 3.01 through open market purchases (provided that such purchases are at or above 100% of the principal amount thereof) and/or by making an
Offer to Purchase to all Holders of Notes at a purchase price equal to 100% of the principal amount thereof, plus accrued interest to but excluding the date of purchase. 

(4) The Net Cash Proceeds of a Notes Collateral Asset Sale not applied pursuant to clause (3) above within 365 days of the
Notes Collateral Asset Sale constitute “Excess Proceeds.” Excess Proceeds of less than $15.0 million will be carried forward and accumulated. When accumulated Excess Proceeds equals or exceeds such amount, the Parent Guarantor must,
within 30 days, make an Offer to Purchase Notes having a principal amount equal to 
  

	 	(A)	accumulated Excess Proceeds, multiplied by 

  

	 	(B)	a fraction (x) the numerator of which is equal to the outstanding principal amount of the Notes and (y) the denominator of which is equal to the outstanding principal amount of the Notes and all Parity Lien Obligations
similarly required to be repaid, redeemed or tendered for in connection with the Notes Collateral Asset Sale, 


  
 33 








 rounded down to the nearest $1,000. The purchase price for the Notes will be 100% of the
principal amount plus accrued interest to but excluding the date of purchase. If the Offer to Purchase is for less than all of the aggregate principal amount of the outstanding Notes and Notes in an aggregate principal amount in excess of the
purchase amount are tendered and not withdrawn pursuant to the offer, the Parent Guarantor will purchase Notes having an aggregate principal amount equal to the purchase amount on a pro rata basis, with adjustments so that only Notes in multiples of
$1,000 principal amount will be purchased; provided, that no Notes of $2,000 or less may be purchased in part. The Company may satisfy the foregoing obligations with respect to any Net Cash Proceeds from a Notes Collateral Asset Sale by
making a Notes Collateral Asset Sale Offer (an “Advance Offer”) with respect to all or a portion of any Net Cash Proceeds (the “Advance Portion”) prior to the expiration of the relevant 365 days or with respect to
Net Cash Proceeds of $15.0 million or less. Upon completion of the Offer to Purchase, Excess Proceeds will be reset at zero, and any Excess Proceeds remaining after consummation of the Offer to Purchase may be used for any purpose not otherwise
prohibited by the Indenture. Additionally, upon consummation or expiration of any Advance Offer, any remaining Net Cash Proceeds shall not be deemed Excess Proceeds and the Company may use such Net Cash Proceeds in any manner not prohibited by the
Indenture. 
 (b) The Company and the Subsidiary Guarantors shall deposit in a segregated cash collateral account (the “Collateral
Proceeds Account”): (1) cash proceeds from any sale, lease, transfer or other disposition (or series of related sales, leases, transfers or dispositions) of Notes Collateral having an aggregate fair market value of more than $5.0 million,
(2) any cash proceeds in excess of $5.0 million of any Notes Collateral taken by eminent domain, expropriation or other similar governmental taking and (3) cash proceeds in excess of $5.0 million of insurance upon any part of the Notes Collateral.
The Collateral Proceeds Account shall be established under the control of the Collateral Agent such that it will have a perfected security interest in the account for the benefit of the Trustee, the Holders and the holders of other Parity Lien
Obligations. Proceeds of the Collateral Proceeds Account may only be released to the Company or the applicable Guarantor for use as permitted by paragraphs (3) or (4) of Section 4.09(a). 

Section 4.10. Restriction on Activities of the Parent Guarantor. The Parent Guarantor (a) shall not engage in any
activities or hold any assets other than (i) the issuance of Capital Stock, (ii) holding 100% of the Capital Stock of the Company and debt securities of the Company that were held by the Parent Guarantor at the date of the Indenture and (iii) those
activities incidental to maintaining its status as a public company, and (b) will not incur any liabilities other than liabilities relating to its 

  
 34 








 
Guarantee of the Notes, its Guarantee of any other debt of the Company, any other Indebtedness it may incur and any other obligations or liabilities incidental to holding 100% of the Capital
Stock of the Company and its liabilities incidental to its status as a public company; provided, however, that for purposes of this covenant only, the term “liabilities” shall not include any liability for the declaration and
payment of dividends on any Capital Stock of the Parent Guarantor; and provided further that if the Parent Guarantor merges with or into the Company, this covenant shall no longer be applicable. 

Section 4.11. SEC Reports and Reports to Holders. (a) Whether or not the Company is then required to file reports with the
SEC, the Company shall file with the SEC all such reports and other information as it would be required to file with the SEC by Section 13(a) or 15(d) under the Exchange Act if it were subject thereto within the time periods specified by the
SEC’s rules and regulations. The Company shall supply the Trustee and each Holder who so requests or shall supply to the Trustee for forwarding to each such Holder, without cost to such Holder, copies of such reports and other information. The
Company shall be deemed to have complied with this Section 4.11 to the extent that the Parent Guarantor files all reports and other information required to be filed with the SEC by Section 13(a) or 15(d) under the Exchange Act relating to the Parent
Guarantor and its consolidated subsidiaries, including the Company. 
 (b) All obligors on the Notes will comply with Section 314(a) of the
Trust Indenture Act. 
 (c) Delivery of these reports and information to the Trustee is for informational purposes only and the
Trustee’s receipt of them will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which
the Trustee is entitled to rely exclusively on Officers’ Certificates). 
 Section 4.12. Repurchase of Notes Upon a Change of
Control. (a) The Company shall commence, not later than 30 days following a Change of Control Repurchase Event, and consummate an Offer to Purchase all Notes then outstanding at a purchase price equal to 101% of their principal
amount plus accrued interest to the Payment Date; provided, that the Company will not be obligated to make an Offer to Purchase upon the occurrence of a Change of Control Repurchase Event if a third party makes an offer to purchase the Notes
in the manner, at the times and price, and otherwise in compliance with the requirements of the Indenture applicable to an Offer to Purchase for a Change of Control Repurchase Event, and purchases all Notes validly tendered and not withdrawn in such
offer to purchase. 
 (b) Notwithstanding anything to the contrary in this Indenture, an Offer to Purchase made upon the occurrence of a
Change of Control Repurchase Event may be made in advance of a Change of Control, conditional upon such Change of Control Repurchase Event, if a definitive agreement is in place for the Change of Control at the time of making the Offer to Purchase
pursuant to the Change of Control Repurchase Event. 

  
 35 








 Section 4.13. Certificate to Trustee. (a) The Company will furnish to the
Trustee annually, on or before a date not more than 90 days after the end of its fiscal year (which, on the date hereof, is a calendar year), a brief certificate which certificate shall comply with the requirements of the Trust Indenture Act (but
which need not contain the statements required by Section 12.04) from its principal executive, financial or accounting officer certifying that (i) a review has been conducted of the activities of the Company, its Subsidiaries and the Parent
Guarantor and their respective performance under the Indenture and (ii) the Company and the Parent Guarantor have fulfilled all obligations under the Indenture (such compliance to be determined without regard to any period of grace or requirement of
notice provided under this Indenture) or specifying each such Default or Defaults and the nature and status thereof.

deliver to the Trustee, as soon as possible and in any event within 30 days after the Company becomes aware of the occurrence of a Default, an Officers’ Certificate setting forth the details of the Default, and the action which the Company
proposes to take with respect thereto. 
 Section 4.14. No Impairment of Security Interests. Neither the Company nor any of its
Restricted Subsidiaries will be permitted to take any action, or knowingly omit to take any action, which action or omission could reasonably be expected to have the result of materially impairing the security interest with respect to the Notes
Collateral for the benefit of the Trustee and the Noteholders. 
 ARTICLE 5

if such notice is given by the Holders), may declare 

  
 38 








 
the principal of, premium, if any, and accrued interest on the Notes to be immediately due and payable, and upon any such declaration of acceleration, such principal of, premium, if any, and
accrued interest shall be immediately due and payable. 
 (b) In the event of a declaration of acceleration because an Event of Default set
forth in clause (d) of Section 6.01 has occurred and is continuing, such declaration of acceleration shall be automatically rescinded and annulled if the event of default triggering such Event of Default pursuant to clause (d) of Section 6.01
shall be remedied or cured by the Parent Guarantor, the Company or the relevant Significant Subsidiary or waived by the holders of the relevant Indebtedness within 60 days after the declaration of acceleration with respect thereto.

nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived and (y) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction. 
 Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may
pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of and interest on the Notes or to enforce the performance of any provision of the Notes or the
Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. 

Section 6.04. Waiver of Past Defaults. Except as otherwise provided in Sections 6.02, 6.07 and 9.02, the Holders of a
majority in principal amount of the outstanding Notes may, by notice to the Trustee, waive all past Defaults and rescind and annul a declaration of acceleration and its consequences. Upon such waiver, the Default will cease to exist, and any
Event of Default arising therefrom will be deemed to have been cured for every purpose under this Indenture, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon. 

Section 6.05. Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes may
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or the
Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction and may take any other action it
deems proper that is not inconsistent with any such direction received from Holders of Notes. 

  
 39 








 Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with
respect to the Indenture or the Notes unless:

Default; 
 (2) the Holders of at least 25% in aggregate principal amount of outstanding Notes make a written request to the
Trustee to pursue the remedy; 
 (3) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against
any costs, liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of indemnity; and 
 (5) during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request. 
 A Holder may not use this
Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder. 
 Section 6.07. Rights
of Holders to Receive Payment. Notwithstanding anything to the contrary, the right of a Holder of a Note to receive payment of principal of, premium, if any or interest on such Note on or after the Stated Maturity thereof, or to
bring suit for the enforcement of any such payment on or after such respective dates, may not be impaired or affected without the consent of that Holder. 

Section 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal or interest specified in clause
(a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue
principal and overdue installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due the Trustee hereunder. 
 Section 6.09. Trustee May File
Proofs of Claim. The Trustee may file proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders allowed in any judicial proceedings relating to the Company or any Guarantor or their respective creditors or property, and is entitled
and empowered to collect, receive and distribute any money, securities or other property payable or deliverable upon conversion or exchange of the Notes or upon any such 

  
 40 








 
claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent
and counsel, and any other amounts due the Trustee hereunder. Nothing in the Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article (including any proceeds distributed to
it upon the exercise of any remedies under the Security Documents), it shall pay out the money in the following order: 

First: to the Trustee for all amounts due hereunder; 

Second: to Holders for amounts then due and unpaid for principal of and interest on the Notes, ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest; and 

Third: to the Company or as a court of competent jurisdiction may direct. 

The Trustee, upon written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section.

 Section 6.11. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted a proceeding to enforce
any right or remedy under this Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Company, any
Guarantors, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company, any Guarantors, the Trustee and the Holders will continue as though no
such proceeding had been instituted. 
 Section 6.12. Undertaking for Costs. In any suit for the enforcement of any right
or remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and
the court may assess reasonable costs, including reasonable attorneys fees, against any party litigant (other than the Trustee) 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 a Holder to enforce payment of principal of or interest on any Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the outstanding Notes. 

Section 6.13. Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders
under this Indenture is intended to be exclusive 

  
 41 








 
of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other right or remedy. 

Section 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or
remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

ARTICLE 7 
 THE
TRUSTEE 
 Section 7.01. General. (a) The duties and responsibilities of the Trustee are as provided by
the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee is subject to this Article.

 (b) Except during the continuance of an Event of Default, the Trustee need perform only those duties that are specifically set forth in
the Indenture and no others, and no implied covenants or obligations will be read into the Indenture against the Trustee. In case an Event of Default has occurred and is continuing, the Trustee shall exercise those rights and powers vested in
it by the 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. 

(c) No provision of the Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct. 
 Section 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act
Sections 315(a) through (d): 
 (1) In the absence of bad faith on its part, the Trustee may rely, and will be protected in
acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness 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, but, in the case of any document which is specifically required to be furnished to the Trustee
pursuant to any provision hereof, the Trustee shall examine the document to determine whether it conforms to the requirements of the Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated
therein). The Trustee, in its discretion, may make further inquiry or investigation into such facts or matters as it sees fit. 

  
 42 








 (2) Before the Trustee acts or refrains from acting, it may require an
Officers’ Certificate or an Opinion of Counsel conforming to Section 12.05 and the Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the certificate or opinion. 

(3) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any
agent appointed with due care. 
 (4) The Trustee will be under no obligation to exercise any of the rights or powers vested
in it by the Indenture at the request or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with
such request or direction. 
 (5) The Trustee will not be liable for any action it takes or omits to take in good faith that
it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the direction of the Holders in accordance with Section 6.05 relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under the Indenture. 

(6) The Trustee may consult with counsel, and the written advice of such counsel or any Opinion of Counsel will be full and
complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(7) No provision of the Indenture will require the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of its duties hereunder, or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it against any loss, liability or expense. 

(8) Any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an
Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company.

 (9) Prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all Events of Default,
the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, Officers’ Certificate, Opinion of Counsel, Board Resolution, statement, instrument, opinion, report, notice, request,
consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document unless requested in writing to do so by the Holders of not less than a majority in 

  
 43 








 
aggregate principal amount of the Notes then outstanding; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it
in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or
liabilities as a condition to proceeding. 
 Section 7.03. Individual Rights of Trustee. The Trustee, in its individual
or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the same with like rights. However,
the Trustee is subject to Trust Indenture Act Sections 310(b) and 311. For purposes of Trust Indenture Act Section 311(b)(4) and (6): 

(a) “cash transaction” means any transaction in which full payment for goods or securities sold is made
within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand; and 

(b) “self-liquidating paper” means any draft, bill of exchange, acceptance or obligation which is made,
drawn, negotiated or incurred for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the
goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the
creditor relationship arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation. 

Section 7.04. Trustee’s Disclaimer. The Trustee (i) makes no representation as to the validity or adequacy of the
Indenture or the Notes, (ii) is not accountable for the Company’s use or application of the proceeds from the Notes and (iii) is not responsible for any statement in the Notes other than its certificate of authentication. 

Section 7.05. Notice of Default. If any Default occurs and is continuing and is known to the Trustee, the Trustee will send
notice of the Default to each Holder within 90 days after it occurs, unless the Default has been cured; provided that, except in the case of a default in the payment of the principal of or interest on any Note, the Trustee may withhold the
notice if and so long as the board of directors, the executive committee or a trust committee of directors of the Trustee in good faith determines that withholding the notice is in the interest of the Holders. Notice to Holders under this
Section will be given in the manner and to the extent provided in Trust Indenture Act Section 313(c). 
 Section 7.06. Reports by Trustee
to Holders. Within 60 days after each May 15, beginning with May 15,         , the Trustee will mail to each Holder, as provided in Trust Indenture Act Section 313(c), a brief report dated as
of such May 15, if required by 

  
 44 








 
Trust Indenture Act Section 313(a), and file such reports with each stock exchange upon which its Notes are listed and with the Commission as required by Trust Indenture Act Section 313(d). 

Section 7.07. Compensation and Indemnity. (a) The Company will pay the Trustee compensation as agreed upon in writing for
its services. The compensation of the Trustee is not limited by any law on compensation of a Trustee of an express trust. The Company will reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances
incurred or made by the Trustee, including the reasonable compensation and expenses of the Trustee’s agents and counsel. 
 (b) The
Company will indemnify the Trustee for, and hold it harmless against, any loss or liability or expense incurred by it without negligence or bad faith on its part arising out of or in connection with the acceptance or administration of the Indenture
and its duties under the Indenture and the Notes, including the costs and expenses of defending itself against any claim or liability and of complying with any process served upon it or any of its officers in connection with the exercise or
performance of any of its powers or duties under the Indenture and the Notes. 
 (c) To secure the Company’s payment obligations in
this Section, the Trustee will have a lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as Trustee, except money or property held in trust to pay principal of, and interest on particular Notes. 

Section 7.08. Replacement of Trustee. (a) (1) The Trustee may resign at any time by written notice to the Company. 

(2) The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by written notice to the
Trustee. 
 (3) If the Trustee is no longer eligible under Section 7.10 or in the circumstances described in Trust Indenture
Act Section 310(b), any Holder that satisfies the requirements of Trust Indenture Act Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(4) The Company may remove the Trustee if: (i) the Trustee is no longer eligible under Section 7.10; (ii) the Trustee is
adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting. 

A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section. 
 (b) If the Trustee has been removed by the Holders, Holders of a majority in principal amount of
the Notes may appoint a successor Trustee with the consent of the Company. Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the 

  
 45 








 
office of Trustee for any reason, the Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its written acceptance within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

(c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the retiring Trustee and to the Company, (i) the
retiring Trustee will transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, (ii) the resignation or removal of the retiring Trustee will become effective, and (iii) the successor
Trustee will have all the rights, powers and duties of the Trustee under the Indenture. Upon request of any successor Trustee, the Company will execute any and all instruments for fully and vesting in and confirming to the successor Trustee all
such rights, powers and trusts. The Company will give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders, and include in the notice the name of the successor Trustee and the
address of its Corporate Trust Office. 
 (d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 will continue for the benefit of the retiring Trustee. 
 (e) The Trustee agrees to give the notices provided
for in, and otherwise comply with, Trust Indenture Act Section 310(b). 
 Section 7.09. Successor Trustee by Merger. If
the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee corporation or national
banking association without any further act will be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee in the Indenture. 

Section 7.10. Eligibility. The Indenture must always have a Trustee that satisfies the requirements of Trust Indenture Act
Section 310(a) and has a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition. 

Section 7.11. Money Held in Trust. The Trustee will not be liable for interest on any money received by it except as it may
agree with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law and except for money held in trust under Article 8. 

Section 7.12. Preferential Collection of Claims Against the Company. The Trustee shall comply with Section 311(a) of the
Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

or by which it is bound, and 
 (E) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of

and each Guarantor’s obligations under its Note Guarantee will terminate, provided the following conditions have been satisfied: 

(A) The Company has deposited with the Trustee, in trust, money and/or U.S. Government Obligations that through the payment of
interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient without consideration of any reinvestment of such principal and interest, as certified by the chief financial officer of the Company

federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case which must be based upon (and accompanied by a
copy of) a ruling of the Internal Revenue Service to the same effect unless there has been a change in applicable federal income tax law after the Issue Date such that a ruling is no longer required or (y) a ruling directed to the Trustee received
from the Internal Revenue Service to the same effect as the Opinion of Counsel described in clause (x), and 
 (2) an
Opinion of Counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940.

Section 8.03. Covenant Defeasance. The Company’s obligations set forth in Section 4.06 through Section 4.11
and Section 4.12, and clauses (c), (d), (e), (h) and (i) of Section 6.01 shall be deemed not to be Events of Default, provided the following conditions have been satisfied: 

(1) The Company has complied with clauses (A), (B)(2), (C), (D) and (E) of Section 8.02; and

In the event the Company exercises its option under Section 8.03 and the Notes are declared due and payable because of an occurrence of an
Event of Default, and the 

  
 49 








 
amount of money and/or U.S. Government Obligations on deposit with the Trustee is sufficient to pay amounts due on the Notes at the Stated Maturity but is not sufficient to pay amounts due on the
Notes at the time of the acceleration resulting from such Event of Default, the Company will remain liable for such payments and any Note Guarantees with respect to such payments will remain in effect. 

Except as specifically stated above, none of the Company’s obligations under the Indenture will be discharged. 

Section 8.04. Application of Trust Money. Subject to Section 8.05, the Trustee will hold in trust the money or U.S.
Government Obligations deposited with it pursuant to Section 8.01, 8.02 or 8.03, and apply the deposited money and the proceeds from deposited U.S. Government Obligations to the payment of principal of and interest on the Notes in accordance with

Company upon request any excess money held by the Trustee at any time and thereupon be relieved from all liability with respect to such money. The Trustee will pay to the Company upon request any money held for payment with respect to the Notes
that remains unclaimed for two years. After payment to the Company, Holders entitled to such money must look solely to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee with respect to
such money will cease. 
 Section 8.06. Reinstatement. If and for so long as the Trustee is unable to apply any money or
U.S. Government Obligations held in trust pursuant to Section 8.01, 8.02 or 8.03 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 the Indenture and the Notes will be reinstated as though no such deposit in trust had been made. If the Company makes any payment of principal of or interest on any Notes because of the reinstatement
of its obligations, it will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held in trust. 

ARTICLE 9 

AMENDMENTS, SUPPLEMENTS AND WAIVERS 

Section 9.01. Amendments Without Consent of Holders. (a) The Company and the Trustee may amend or supplement the Indenture,

the “Description of Notes” in the prospectus pursuant to which the Initial Notes were offered; or 
 (8) to
provide for any Guarantee of the Notes, to secure the Notes or any Guarantee of the Notes or to confirm and evidence the release, termination or discharge of any Guarantee of or Lien securing the Notes when such release, termination or discharge is
permitted by the Indenture. 
 (b) The Security Documents may be amended without any Holder’s consent to add additional secured
creditors holding other Parity Lien Obligations or Junior Lien Obligations so long as such Obligations (and the Liens securing them) are not prohibited by the Indenture. 

Section 9.02. Amendments with Consent of Holders. (a) Except as otherwise provided in Sections 6.02, 6.04 and 6.07 or
paragraph (b), the Company and the Trustee may modify, amend or waive the Indenture, the Notes or the Security Documents with the written consent of the Holders of not less than a majority in principal amount of the outstanding Notes. 

(b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder affected, an amendment or waiver may not 

(1) change the Stated Maturity of the principal of, or any installment of interest on, any Note, 

(2) reduce the principal amount of, or premium, if any, or interest on, any Note, 

(3) change the optional redemption dates or optional redemption prices of the Notes from that stated in Section 3.01,

 (4) change the place or currency of payment of principal of, or premium, if any, or interest on, any Note,

 (8) release any Guarantor from its Note Guarantee, except as provided in the Indenture,

waiver may release from the Lien of the Indenture and the Security Documents all or substantially all of the Notes Collateral.

of the requisite percentage in principal amount of the outstanding Notes. After an amendment, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the
amendment, supplement or waiver. The Company will send supplemental indentures to Holders upon request. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of
any such supplemental indenture or waiver. 

  
 52 








 Section 9.03. Effect of Consent. (a) After an amendment, supplement or waiver
becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement
or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder. 

(b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that
the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed terms. The Trustee may also place an appropriate notation on any Note thereafter
authenticated. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion. 

Section 9.04. Trustee’s Rights and Obligations. The Trustee is entitled to receive, and will be fully protected in
relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by the Indenture. If the Trustee has received such an Opinion of Counsel, it shall
sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights,
duties or immunities under the Indenture. 
 Section 9.05. Conformity with Trust Indenture Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. 
 ARTICLE 10 

GUARANTEES 

Section 10.01. The Guarantees. Subject to the provisions of this Article, each Guarantor hereby irrevocably and
unconditionally guarantees, jointly and severally, on a senior basis, the full and punctual payment (whether at Stated Maturity, upon redemption, purchase pursuant to an Offer to Purchase or acceleration, or otherwise) of the principal of, premium,
if any, and interest on, and all other amounts payable under, each Note, and the full and punctual payment of all other amounts payable by the Company under the Indenture. Upon failure by the Company to pay punctually any such amount, each

Indenture or any Note, by operation of law or otherwise; 

  
 53 








 (2) any modification or amendment of or supplement to the Indenture or any Note;

 (3) any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy,
reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in the Indenture or any Note; 

(4) the existence of any claim, set-off or other rights which each Guarantor may have
at any time against the Company, the Trustee or any other Person, whether in connection with the Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory
counterclaim; 
 (5) any invalidity or unenforceability relating to or against the Company for any reason of the Indenture
or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on any Note or any other amount payable by the Company under the Indenture; or 

(6) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other
circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Guarantor’s obligations hereunder. 

Section 10.03. Discharge; Reinstatement. Each Guarantor’s obligations hereunder will remain in full force and effect
until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under the Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or
any other amount payable by the Company under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guarantor’s obligations hereunder with
respect to such payment will be reinstated as though such payment had been due but not made at such time. 
 Section 10.04. Waiver by the
Guarantors. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company
or any other Person. 
 Section 10.05. Subrogation and Contribution. Upon making any payment with respect to any
obligation of the Company under this Article, the Guarantor making such payment will be subrogated to the rights of the payee against the Company with respect 

  
 54 








 
to such obligation, provided that such Guarantor may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any
other Guarantor, with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid. 

Section 10.06. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under the
Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Indenture are nonetheless payable by the Guarantors hereunder forthwith on
demand by the Trustee or the Holders. 
 Section 10.07. Limitation on Amount of Guarantee. Notwithstanding anything to
the contrary in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable
fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor
under its Note Guarantee are limited to the maximum amount that would not render the Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision
of state law. 
 Section 10.08. Execution and Delivery of Guarantee. The execution by each Guarantor of this Indenture,
and the execution by each future Subsidiary Guarantor of a supplemental indenture in the form of Exhibit B hereto, evidences the Note Guarantee of such Guarantor, whether or not the person signing as an officer of such Guarantor still holds
that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor. 

Section 10.09. Release of Guarantee. The Note Guarantee of a Subsidiary Guarantor will terminate upon 

(1) the release or discharge (other than a discharge through payment thereon) of the Indebtedness of such Subsidiary that
resulted in the obligation to Guarantee the Notes (except that this shall not apply to AK Tube LLC and AK Steel Properties, Inc., which shall only be released pursuant to this provision if such Guarantor has no outstanding Indebtedness other than
Indebtedness under Section 4.07(a)(1), (2), (3) or (5) or permitted under Section 4.07(b)); 
 (2) the disposition
of capital stock in compliance with this Indenture of such Subsidiary such that it is no longer a Subsidiary, 
 (3) upon
defeasance or satisfaction and discharge of the Notes, as provided in Article 8, 
 (4) if the Guarantee was not required by
the terms of the Indenture, at any time; provided that after giving effect to such release, the Company would be in compliance with Section 4.07. 

  
 55 








 Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of
Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Note Guarantee. 

ARTICLE 11 

SECURITY ARRANGEMENTS 

Section 11.01. Collateral Agent. (a) The Notes Collateral will be pledged pursuant to the Security Documents
to the Collateral Agent, on behalf of the holders of the Notes and all holders of future Parity Lien Obligations. Each Holder, by its acceptance of any Notes and the Note Guarantees, consents and agrees to the terms of the Security Documents as
the same may be in effect or as may be amended from time to time in accordance with their terms and authorizes and directs the Collateral Agent and the Trustee, as applicable, to become party to and perform their respective obligations and exercise
their respective rights under the Security Documents in accordance therewith, to bind the Holders on the terms set forth in the Security Documents, and to execute any and all documents, amendments, waivers, consents, releases or other instruments
required or authorized to be executed by it pursuant to the terms thereof. 
 (b) Subject in all respects to the terms of the Collateral
Trust Agreement and the other Security Documents, the Collateral Agent will hold (directly or through co-trustees or agents), and will be entitled to enforce on behalf of the Holders of Notes and the holders of all other Parity Lien Obligations, all
Liens on the Notes Collateral. 
 (c) The Collateral Agent is authorized and empowered to appoint one or more co-Collateral Agents as it
deems necessary or appropriate. 
 (d) In acting as Collateral Agent or Co-Collateral Agent, the Collateral Agent and each Co-Collateral
Agent may rely upon and enforce each and all of the rights, powers, immunities, indemnities and benefits of the Trustee under Article 7 hereof. 

(e) At all times when the Trustee is not itself the Collateral Agent, the Company will deliver to the Trustee copies of all Security Documents
delivered to the Collateral Agent and copies of all documents delivered to the Collateral Agent pursuant to this Indenture and the Security Documents. 

(f) The Collateral Agent may resign or may be removed in accordance with the provisions set forth in the Collateral Trust Agreement. 

(g) This Section 11.01 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the
Collateral Trust Agreement. 

  
 56 








 Section 11.02. Security. (a) In order to secure the Obligations of the Company
under this Indenture and the Notes, the Company and the Collateral Agent have entered into simultaneously with the execution of this Indenture each Security Document referred to in the last sentence of the definition thereof, in each case together
with evidence (which shall be delivered by the Company to the Trustee) that all other documents and instruments, including Uniform Commercial Code financing statements and all other actions required by law or the terms of the Security Documents to
be filed, registered or recorded to create the Liens intended to be created by the Security Documents and perfect such Liens to the extent required by the Security Documents, shall have been filed, registered or recorded or delivered to the
Collateral Agent for filing, registration or the recording concurrently with, or promptly following, the execution and delivery of each such Security Document. In the case of all real property, as to which a Mortgage is delivered, the Company shall
also deliver (the following, collectively, “Mortgage Deliverables”) (i) a policy or policies of lender’s title insurance in an amount equal to the lesser of (x) the fair market value of the real property subject to the Mortgage
and (y) the aggregate principal amount of the Notes and any Parity Lien Obligations, proportionally allocated to the real property subject to the Mortgage (which amount of title insurance the Company shall increase, if applicable, upon the issuance
of any Additional Notes or Parity Lien Obligations but in no event shall the Company be required to increase such amount in excess of the fair market value of such property), as is customarily determined for transactions of a similar nature, paid
for by the Company, issued by a nationally recognized title insurance company, insuring the Lien of each Mortgage as a valid first Lien on the mortgaged property described therein, free of any other Liens except Liens permitted by the terms of this
Indenture and the applicable Security Documents, together with coinsurance, reinsurance and such endorsements to such policy or policies as are customary, (ii) a survey of the property subject to any such Mortgage (such surveys, collectively, the
“Surveys”) certified to the Company, Collateral Agent and the title company, meeting minimum standard detail requirements for ALTA/ACSM Land Title Surveys by a land surveyor duly registered and licensed in the state in which such
real property is located, (iii) an Opinion of Counsel of the type specified in Section 11.02(b) with respect to any such Mortgage, (iv) evidence of insurance required to be maintained pursuant to the Mortgages and this Indenture, and (v) flood
hazard determination certificates and, if required, notices to the record owner of any improvements in a special flood hazard area, together with evidence of acceptable flood insurance coverage. With respect to any Mortgaged Premises (as
defined in the Collateral Trust Agreement) that, as of the date hereof, is covered by a Mortgage (as defined in the 2012 Indenture) (“Existing Mortgage”), an endorsement to the existing title insurance policy delivered pursuant to
Section 11.02 of the 2012 Indenture may be delivered in lieu of a new title insurance policy. Notwithstanding the foregoing, if the Company is unable to provide a Mortgage on any real property required to be so mortgaged hereunder or any applicable
Mortgage Deliverables on the Issue Date (the foregoing, collectively, the “Issue Date Mortgage Deliverables”), the Company need not provide such Issue Date Mortgage Deliverables on such date, but shall use commercially reasonable
efforts to do so as promptly as practicable and in any event within 180 days from such date. 

  
 57 








 (b) From and after the Issue Date, if (1) any real property, plant or equipment (other than
Excluded Property) is acquired by the Company or a Subsidiary Guarantor that is not automatically subject to a perfected security interest under the Security Documents, (2) any real property, plant or equipment which was Excluded Property ceases to
be Excluded Property, or (3) any Subsidiary becomes a Subsidiary Guarantor, then the Company or such Subsidiary Guarantor will, as soon as reasonably practical after such property’s acquisition or it no longer being Excluded Property or such
Subsidiary becoming a Guarantor, provide security over such property (or, in the case of a new Subsidiary Guarantor, provide security over all of its assets constituting Notes Collateral except Excluded Property) in favor of the Collateral Agent and
deliver any required supplement to the Security Agreement and any required Mortgages necessary to grant security interests in such property, and, in the case of real property, as to which a Mortgage is required to be delivered, Mortgage
Deliverables. Notwithstanding anything herein contained to the contrary, (i) in the case of the Issue Date Mortgage Deliverables, the real property secured by Mortgages and the amount of title insurance issued shall be the same as was so secured and
issued in connection with that certain Indenture dated as of November 20, 2012 (the “2012 Indenture”) among AK Steel Company, as Issuer, AK Steel Holding Company, U.S. Bank National Association, as Trustee and U.S. Bank National
Association, as Collateral Agent) and (ii) the Company shall be required to deliver a title insurance policy with respect to any real property acquired after the Issue Date only to the extent that the aggregate insured amount of all title insurance
then in effect is less than the then outstanding aggregate principal amount of the obligations then secured by the Mortgages so long as the Company certifies that (1) to its reasonable belief, the existing fair market value of collateral
insured by title insurance equals or exceeds the aggregate principal amount of the bonds then outstanding and (2) the aggregate amount of title insurance then in effect (i.e., exclusive of policies for real property no longer owned by the Company or
a Subsidiaries) equals or exceeds the aggregate principal amount of bonds then outstanding, provided further that as to this subsection (2), to the extent that the parties hereto reasonably determine that the cost of acquiring title insurance is not
proportionate to the benefit of such insurance (i.e. the value of the real property at issue significantly exceeds any shortfall between the then outstanding aggregate title insurance amount and the principal amount of the then outstanding bonds or
the title premium would be excessive relative to the benefits of such increased insurance), such new title insurance amounts shall not be required. Any security interest provided pursuant to this Section 11.02(b) that requires execution of new
Security Documents by a new Guarantor or of a new Mortgage shall be accompanied by such Opinions of Counsel as to the enforceability of such Security Documents and the validity and perfection of the Liens on such property as is customarily given by
counsel in the relevant jurisdiction, in form and substance customary for such jurisdiction and with customary qualifications and exceptions. 

(c) The Company and the Guarantors shall comply with all covenants and agreements contained in the Security Documents. 

(d) Each Holder, by accepting a Note, agrees to all of the terms and provisions of the Security Documents, as the same may be amended from
time to time pursuant to the provisions of this Indenture and the Security Documents. 

  
 58 








 (e) The Company and each Guarantor shall execute any and all further documents, financing
statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, fixture filings, modifications to or amendments and restatements of Mortgages and other documents and recordings
of Liens in stock registries), to the extent required under the Security Documents, to ensure that the Liens of the Security Documents on the Notes Collateral remain perfected with the priority set forth by the Security Documents, all at the
reasonable expense of the Company and Guarantors and provide to the Collateral Agent and the Trustee, from time to time upon reasonable request, evidence reasonably satisfactory to the Collateral Agent and the Trustee as to the perfection and
priority of the Liens created or intended to be created by the Security Documents. 
 (f) Upon request of the Collateral Agent at any time
after an Event of Default has occurred and is continuing, the Company will, and will cause the Subsidiary Guarantors to, (i) permit the Collateral Agent or any advisor, auditor, consultant, attorney or representative acting for the Collateral Agent,
upon reasonable notice to the Company and during normal business hours, to visit and inspect any of the property of the Company and the Subsidiary Guarantors, to review, make extracts from and copy the books and records of the Company and the
Subsidiary Guarantors relating to any such property, and to discuss any matter pertaining to any such property with the officers and employees of the Company and the Subsidiary Guarantors, and (ii) deliver to the Collateral Agent such reports,
including valuations, relating to any such property or any Lien thereon as the Collateral Agent may reasonably request. 
 (g) The Company
will bear and pay all reasonable, documented, out-of-pocket legal expenses, collateral audit and valuation costs, filing fees, insurance premiums and other reasonable costs associated with the performance of the obligations of the Company and the
Subsidiary Guarantors of the Company set forth in this Section 11.02 and also will pay, or promptly reimburse the Trustee and Collateral Agent for, all reasonable, documented, out-of-pocket costs and expenses incurred by the Trustee or Collateral
Agent in connection therewith, including all reasonable, documented, out-of-pocket fees and charges of any advisors, auditors, consultants, representatives or any one law firm (except to the extent local counsel may be reasonably required due to the
jurisdiction in which any part of the Notes Collateral is located) acting for the Trustee or for the Collateral Agent. 
 (h)
Notwithstanding the foregoing, the Company and any Subsidiary Guarantor shall not be required to provide Mortgages on real property (including improvements thereon) with a greater of book and fair market value of less than $10.0 million and
vehicles. 
 Section 11.03. Authorization of Actions to be Taken. (a) The Collateral Agent and the Trustee are authorized
and empowered to become party to the Security Documents and to receive on behalf of the Holders, any funds collected or distributed under the Security Documents to which the Collateral Agent or Trustee is a party and to make further distributions of
such funds to the Holders of Notes according to the provisions of this Indenture. 

  
 59 








 (b) Subject to the Collateral Trust Agreement and Article 7, unless inconsistent with applicable
law or the other Security Documents, the Collateral Agent is authorized and empowered if an Event of Default has occurred and is continuing to institute and maintain such suits and proceedings as are necessary to protect or enforce the Liens on the
Notes Collateral or the other rights under the Security Documents to which the Collateral Agent is a party. 
 Section 11.04.
Determinations Relating to Notes Collateral. Except for any consent, approval or action by the Collateral Agent in the ordinary course of the performance of the Collateral Agent’s duties under this Indenture or the Security
Documents, in the event (i) the Collateral Agent shall receive any written request from the Company, a Guarantor or the Trustee under any Security Document for consent or approval with respect to any matter or thing relating to any Notes Collateral
or the Company’s or such Guarantor’s obligations with respect thereto, (ii) there shall be due to or from the Trustee or the Collateral Agent under the provisions of any Security Document any material performance or the delivery of any
material instrument or (iii) the Collateral Agent shall become aware of any nonperformance by the Company or a Guarantor of any covenant or any breach of any representation or warranty of the Company or such Guarantor set forth in any Security
Document, then, in each such event, the Collateral Agent shall be entitled to hire experts, consultants, agents and attorneys to advise the Collateral Agent on the manner in which the Collateral Agent should respond to such request or render any
requested performance or respond to such nonperformance or breach. The Collateral Agent shall be fully protected in the taking of any action recommended or approved by any such expert, consultant, agent or attorney or agreed to by the Holders of a
majority in principal amount of the outstanding Notes. 
 Section 11.05. Release of Liens. (a) The Liens on the Notes
Collateral securing the Notes and the Note Guarantees will be automatically released: 
 (i) upon payment in full of
principal, interest and all other Obligations on the Notes or satisfaction and discharge of this Indenture or defeasance (including covenant defeasance of the Notes); 

(ii) [reserved]; 

(iii) upon release of a Note Guarantee (with respect to the Liens securing such Note Guarantee granted by such Subsidiary
Guarantor); 
 (iv) in connection with any disposition of Notes Collateral to any Person other than the Company or any
Subsidiary Guarantor (but excluding any transaction subject to Article 5 where the recipient becomes an obligor) that is permitted by this Indenture (with respect to the Lien on such Notes Collateral); 

(iv) in whole or in part, with the consent of the Holders of the requisite percentage of Notes in accordance with the
provisions of Article 9; and 
 (v) with respect to any portion of the Notes Collateral, if such portion becomes Excluded
Property. 

  
 60 








 Each of the releases described in clauses (i), (iii) and (iv) shall be effected by the Collateral
Agent without the consent of the Holders or any action on the part of the Trustee. Upon compliance by the Company with the conditions precedent required by this Indenture, the Trustee or the Collateral Agent shall promptly cause the applicable
Notes Collateral to be released and re-conveyed to the Company.
 The Trustee and the Collateral Agent will, promptly upon the request of
the Company, do all reasonable things, presently or in the future, to effect and evidence the release of the security interests and liens upon the satisfaction of the conditions for such release described herein. 

(b) At the request of the Company or the applicable Subsidiary Guarantor, as the case may be: 

(1) if any part of the Notes Collateral is subject to any Lien permitted under Section 4.06 that is senior to the Liens
securing the Notes Collateral as a matter of law, the Collateral Agent will be authorized to execute any document evidencing such subordination; and 

(2) if any part of the Notes Collateral is secured by a Lien of the type described in Section 4.06(a)(5), and the terms of the
Lien prohibit the existence of a junior Lien on the applicable property, the Collateral Agent will be authorized to release the Lien on such Notes Collateral and execute any document evidencing such release; provided, that immediately upon
the ineffectiveness, lapse or termination of any such restriction, the Company or the applicable Guarantor, as the case may be, will take all necessary actions in order to secure the Notes Collateral subject to such permitted Lien in the same manner
upon which it was secured prior to the imposition of such permitted Lien. 
 (c) Upon delivery to the Collateral Agent of an Officer’s
Certificate requesting execution of an instrument confirming the release of the Liens pursuant to Section 11.05(a), accompanied by: 

(1) an Opinion of Counsel confirming that such release is permitted by Section 11.05(a); 

(2) all instruments requested by the Company to effectuate or confirm such release; and 

(3) such other certificates and documents as the Collateral Agent may reasonably request to confirm the matters set forth in
Section 11.05(a), 
 the Collateral Agent is hereby authorized to, and shall, if such instruments and confirmation are reasonably satisfactory to the
Collateral Agent, promptly execute and deliver such instruments. 
 (d) All instruments effectuating or confirming any release of any Liens
will have the effect solely of releasing such Liens as to the Notes Collateral described therein, on customary terms and without any recourse, representation, warranty or liability whatsoever. 

  
 61 








 (e) The Company will bear and pay all reasonable costs and expenses associated with any release
or subordination of Liens pursuant to this Section 11.04, including all reasonable fees and disbursements of any attorneys or representatives acting for the Trustee or for the Collateral Agent. 

(f) Any release of Notes Collateral in accordance with the provisions of this Indenture and the Security Documents will not be deemed to
impair the security under this Indenture, and any engineer or appraiser may rely on this Section 11.05(f) in delivering a certificate requesting release so long as all other provisions of this Indenture and the Trust Indenture Act with respect to
such release have been complied with. 
 (g) At any time when a Default or Event of Default has occurred and is continuing and the maturity
of the Notes has been accelerated (whether by declaration or otherwise) and the Trustee (if not then the Collateral Agent) has delivered a notice of acceleration to the Collateral Agent, no release of Notes Collateral pursuant to the provisions of
this Indenture or the Security Documents will be effective as against the Holders. 
 Section 11.06. Filing, Recording and
Opinions. (a) The Company will comply with Section 314(d) of the Trust Indenture Act, relating to the release of property and to the substitution therefor of any property to be pledged as collateral for the Notes. Any
certificate or opinion required by Section 314(d) of the Trust Indenture Act may be made by an officer of the Company except in cases where Section 314(d) requires that such certificate or opinion be made by an independent engineer, appraiser or
other expert. Notwithstanding anything to the contrary herein, the Company and the Subsidiary Guarantors will not be required to comply with all or any portion of Section 314(d) of the Trust Indenture Act if they determine, in good faith based on
advice of outside counsel, that under the terms of that section and/or any interpretation or guidance as to the meaning thereof of the Commission and its staff, including “no action” letters or exemptive orders, all or any portion of
Section 314(d) of the Trust Indenture Act is inapplicable to the released Notes Collateral. 
 (b) If any Notes Collateral is released in
accordance with this Indenture or any Security Document at a time when the Trustee is not itself also the Collateral Agent and if the Company has delivered the certificates and documents required by the Security Documents and Section 11.05, the
Trustee will determine whether it has received all documentation required by Section 314(d) of the Trust Indenture Act in connection with such release and, based on such determination and the Opinion of Counsel delivered pursuant to Section 11.05,
will, upon request, deliver a certificate to the Collateral Agent setting forth such determination. 
 (c) The Company will deliver to the
Trustee within 120 days after the end of each fiscal year, the Opinion of Counsel required pursuant to Section 314(b)(2) of the Trust Indenture Act. 

  
 62 








 Section 11.07. Purchaser Protected. In no event shall any purchaser in good
faith of any property purported to be released hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for
the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article 11 to be sold be under any
obligation to ascertain or inquire into the authority of the Company or the applicable Guarantor to make any such sale or other transfer. 

Section 11.08. Powers Exercisable by Receiver or Trustee. In case the Notes Collateral shall be in the possession of a
receiver or trustee, lawfully appointed pursuant to the terms of this Indenture and the Collateral Trust Agreement and the other Security Documents, the powers conferred in this Article 11 upon the Company or a Guarantor with respect to the release,
sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Guarantor or of any officer or
officers thereof required by the provisions of this Article 11; and if the Trustee shall be in the possession of the Notes Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.
